Kinds of Asian Terms modified by Asian Selected AbstractsASIANS IN AMERICA'S SUBURBS: PATTERNS AND CONSEQUENCES OF SETTLEMENT§GEOGRAPHICAL REVIEW, Issue 2 2005EMILY SKOP ABSTRACT. In an effort to provide a more complex and multifaceted understanding of the process of spatial assimilation, this article explores alternative paths in understanding racial/ ethnic minority residential patterns. It scrutinizes patterns of contemporary Asian Indian and Chinese settlement in two metropolitan areas: Austin, Texas and Phoenix, Arizona. Though not particularly evolved in terms of their Asian immigrant settlement or dynamics, Austin and Phoenix represent the growing number of newly emergent Asian centers throughout the nation that have developed with the rapid rise of immigration from these two countries in the past several decades. The analysis utilizes records from the 2000 census to document and map Asian Indian and Chinese settlement within each metropolitan area and to investigate whether-and to what degree-each group is clustered or dispersed. The article then raises important questions about the consequences of concentration and dispersal for the incorporation of Asian Indian and Chinese residents. [source] Female Gender and the Risk of Rupture of Congenital Aneurysmal Fistula in AdultsCONGENITAL HEART DISEASE, Issue 1 2008Salah A.M. Said MD ABSTRACT Aims., To delineate the risk factors for rupture of congenital aneurysmal fistulas in adult patients. Methods., We conducted a literature search of the Medline database using Pubmed search interface to identify reports dealing with rupture of congenital aneurysmal fistulas in an adult population. The search included the English and non-English languages between 1963 and 2005. Results., Fourteen adult patients (12 females) with serious and life-threatening complications secondary to aneurysmal fistulas were reported. Mean age was 62.9 years. The ethnic origins of these 14 patients were 9 Asian and 5 Caucasian. Most patients have had no other cardiac malformations. Five patients had a history of hypertension. One patient was asymptomatic. In 13 symptomatic patients, the clinical presentation was cardiac tamponade, pericardial effusion, syncope, heart failure, chest pain, dyspnea, fatigue, distal thromboembolic events with infarction, shock, and/or sudden death. Aneurysmal fistulas were identified in 10 patients; of these 6 were of the saccular type. Rupture occurred in 9 patients (8 females and 1 male). Eleven patients were treated surgically with 1 late death. Two male subjects experienced sudden unexpected cardiac death. Conclusion., Rupture of congenital aneurysmal fistulas occurred more often in females. Identified risk factors for rupture, hemopericardium, tamponade, and death were among others saccular aneurysm, Asian ethnic race, origin of the aneurysmal fistulas from the left coronary artery and a history of hypertension may play a role. In this article, we present a literature review of congenital aneurysmal fistulas associated with or without rupture and a case report of a woman with unruptured aneurysmal fistula. [source] Genetic Identification of Pelagic Shark Body Parts for Conservation and Trade MonitoringCONSERVATION BIOLOGY, Issue 4 2002Mahmood Shivji Difficulties with the identification of many commonly fished sharks and their body parts has resulted in a global dearth of catch and trade information, making reliable assessment of exploitation effects and conservation needs for individual species nearly impossible. We developed and tested a highly streamlined molecular genetic approach based on species-specific, polymerase-chain-reaction primers in an eight-primer multiplex format to discriminate simultaneously between body parts from six shark species common in worldwide pelagic fisheries. The species-specific primers are based on DNA sequence differences among species in the nuclear ribosomal internal transcribed spacer 2 locus. The primers and multiplex format accurately and sensitively distinguished samples from each of three lamnid ( Isurus oxyrinchus, Isurus paucus, and Lamna nasus) and three carcharhinid ( Prionace glauca, Carcharhinus obscurus, and Carcharhinus falciformis) species from all but one other shark species encountered in the North Atlantic fishery. Furthermore, the three lamnid primers were robust enough in their discriminatory power to be useful for species diagnosis on a global scale. Preliminary testing of dried fins from Asian and Mediterranean commercial markets suggests that our genetic approach will be useful for determining the species of origin of detached fins, thus allowing the monitoring of trade in shark fins for conservation assessment. Our approach will also facilitate detection of products from protected and other at-risk shark species and may prove useful as a model for development of the high-throughput, genetic, species-diagnosis methods typically required in conservation and management contexts. Resumen: La conservación y manejo de tiburones fundamentado a nivel de especie es una necesidad imperativa debido a la creciente demanda de aletas de tiburón y el reconocimiento de que las especies individuales de tiburones responden de manera distinta a la explotación. Las dificultades para la identificación de muchos tiburones capturados comúnmente, así como de partes de su cuerpo, han resultado en una escasez global de información sobre capturas y comercialización, haciendo casi imposible el poder realizar evaluaciones de los efectos de la explotación y de las necesidades de conservación. Desarrollamos y evaluamos un método altamente estilizado de genética molecular basado en detonadores de la reacción en cadena de la polimerasa, especie-específicos, en un formato múltiple de ocho detonadores para discriminar simultáneamente entre las partes del cuerpo de seis especies de tiburones provenientes de pesquerías pelágicas mundiales comunes. Los detonadores especie-específicos están basados en diferencias en las secuencias de ADN entre especies del locus espaciador 2 nuclear, ribosomal, transcrito. Los detonadores y el formato múltiple distinguen muestras con precisión y sensitividad de cada uno de los tres lámnidos ( Isurus oxyrinchus, Isurus paucus y Lamna nasus) y tres especies de carcarínidos ( Prionace glauca, Carcharhinus obscurus y Carcharhinus falciformis) especies todas encontradas en las pesquerías de Norteamérica, excepto una. Mas aún, los detonadores de los tres lamnidos fueron lo suficientemente robustos en su poder discriminante como para ser usados para el diagnóstico de especies a escala mundial. Las pruebas preliminares de aletas secas de los mercados comerciales de Asia y el Mediterráneo sugieren que nuestro método genético puede ser útil para determinar la especie de origen de las aletas separadas, permitiendo así usar el monitoreo de las aletas de tiburón para evaluaciones de conservación. Nuestro método también podría facilitar la detección de productos provenientes de especies protegidas o en riesgo y podría resultar útil como un modelo para el desarrollo de métodos genéticos de alto rendimiento para el diagnóstico de especies, métodos típicamente requeridos en los contextos de conservación y manejo. [source] Ethnic variations in facial skin neurosensitivity assessed by capsaicin detection thresholdsCONTACT DERMATITIS, Issue 6 2009Roland Jourdain Background: Ethnic variations in sensitive skin have not been thoroughly explored and remain controversial. Objective: To objectively assess ethnic variations in facial skin neurosensitivity through individual detection thresholds of topically applied capsaicin. Patients/Methods: The single-blind, controlled study was performed in 144 women from three ethnicities: Asian, African, and Caucasian. Five solutions with increasing capsaicin concentration were successively applied to one side of nasolabial folds, while the other side simultaneously received the vehicle as control. The test was discontinued when the volunteer reported on the capsaicin side a sensation whatever its nature. Otherwise the experimenter continued the test, using the next solution with higher capsaicin content and so on, until the subject experienced a sensation on the capsaicin side. Results: Each ethnic group was divided into six sub-groups according to the level of sensitivity to capsaicin, i.e. from detection of the lowest concentration up to no detection of the highest concentration, 100-fold higher. Asian women tended to have higher capsaicin detection thresholds than Caucasians, but lower thresholds than Africans. Nevertheless, the distribution did not greatly differ between the three ethnicities. Conclusions: The capsaicin skin neurosensitivity test is painless and the changes across individuals of different ethnic backgrounds appear minimal. [source] Optimal Board Monitoring in Family-owned Companies: Evidence from AsiaCORPORATE GOVERNANCE, Issue 1 2010En-Te Chen ABSTRACT Manuscript Type: Empirical Research Question/Issue: We propose that high levels of monitoring are not always in the best interests of minority shareholders. In family-owned companies the optimal level of board monitoring required by minority shareholders is expected to be lower than that of other companies. This is because the relative benefits and costs of monitoring are different in family-owned companies. Research Findings/Insights: At moderate levels of board monitoring, we find concave relationships between board monitoring variables and firm performance for family-owned companies but not for other companies. The optimal level of board monitoring for our sample of Asian family-owned companies equates to board independence of 38 per cent, separation of the chairman and CEO positions, and establishment of audit and remuneration committees. Additional testing shows that the optimal level of board monitoring is sensitive to the magnitude of the agency conflict between the family group and minority shareholders and the presence of substitute monitoring. Theoretical/Academic Implications: This study shows that the effect of additional monitoring on agency costs and firm performance differs across firms with different ownership structures. Practitioner/Policy Implications: For policymakers, the results show that more monitoring is not always in the best interests of minority shareholders. Therefore, it may be inappropriate for regulators to advise all companies to follow the same set of corporate governance guidelines. However, our results also indicate that the board governance practices of family-owned companies are still well below the identified optimal levels. [source] Growth, Poverty Reduction and Development Assistance in Asia: Options and ProspectsDEVELOPMENT POLICY REVIEW, Issue 2006John Farrington This article examines a number of policy challenges and dilemmas arising from the pattern of growth and poverty reduction in Asia, central to which is the fact that growth and poverty reduction have been more rapid in Asia than in any other region in the last decade, and yet Asia still contains the majority of the world's poor. The article examines the record of achievement, possible future trends including emerging patterns of inequality, and likely future priorities for poverty-reduction policies. It assesses the role of official development assistance and suggests how it may evolve in future, in part linked with responses to a number of challenges shared between Asian and OECD countries, including energy supply, environmental issues including climate change, and financial stability. [source] The prevalence of depressive symptoms in a white European and South Asian population with impaired glucose regulation and screen-detected Type 2 diabetes mellitus: a comparison of two screening toolsDIABETIC MEDICINE, Issue 8 2010N. Aujla Diabet. Med. 27, 896,905 (2010) Abstract Aims, To compare the identification of prevalent depressive symptoms by the World Health Organization-5 Wellbeing Index (WHO-5) and Centre for Epidemiological Studies Depression Scale (CES-D) for South Asian and white European people, male and female, attending a diabetes screening programme, and to explore the adequacy of the screening tools for this population. An additional aim was to further explore associations of depressive symptoms with impaired glucose regulation (IGR) and Type 2 diabetes mellitus (Type2 DM). Methods, Eight hundred and sixty-four white European (40,75 years old) and 290 South Asian people (25,75 years old) underwent an oral glucose tolerance test (OGTT), detailed history and anthropometric measurements and completed the WHO-5 and CES-D. Depressive symptoms were defined by a WHO-5 score , 13, and CES-D score , 16. Results, Unadjusted prevalence of depressive symptoms with the WHO-5, for people with Type2 DM was 42.3% (47.4% in white European; 28.6% in South Asian) and for IGR 30.7% (26% in white European; 45.8% in South Asian). With the CES-D, the prevalence in Type2 DM was 27.2% (25.4% in white European; 31.8% in South Asian) and for IGR 30.7% (27.8% in white European; 40.7% in South Asian). Statistically significant differences in the prevalence of depressive symptoms for sex or ethnicity were not identified. Odds ratios adjusted for age, sex and ethnicity showed no significant association of depression with Type2 DM or IGR, with either WHO-5 or CES-D. Agreement was moderate (, = 0.48, 95% confidence intervals 0.42,0.54), and reduced when identifying depressive symptoms in people with Type2 DM. For this group, a WHO-5 cut-point of , 10 was optimal. Conclusions, Depressive symptoms, identified by WHO-5 or CES-D, were not significantly more prevalent in people with Type2 DM or IGR. The WHO-5 and CES-D differed in their identification of depressive symptoms in people with Type2 DM, though discrepancies between sex and ethnicity were not identified. [source] Validation of an algorithm combining haemoglobin A1c and fasting plasma glucose for diagnosis of diabetes mellitus in UK and Australian populationsDIABETIC MEDICINE, Issue 2 2009S. E. Manley Abstract Aim, To determine whether glycated haemoglobin (HbA1c) can be used in combination with fasting plasma glucose (FPG) for the diagnosis of diabetes in patients with impaired fasting glucose (IFG) and in a broader spectrum of patients. Methods, An algorithm was derived from oral glucose tolerance test (OGTT) capillary samples in 500 consecutive UK patients with IFG by World Health Organization criteria. It was validated in a further 500 UK patients and, with venous specimens, in 1175 unselected Australian patients. Results, The derivation cohort was aged 61 years (50,69 years) (median IQ range) with 52% male and 12% South Asian. Diabetes Control and Complications Trial-aligned HbA1c was 6.2% (5.8,6.6%) (reference interval < 6.0%) and FPG 6.7 mmol/l (6.3,7.2 mmol/l). FPG was in the diabetes range in 36% of patients, with an OGTT identifying a further 12% with diabetes. The derived algorithm, (HbA1c , 6.0% with FPG < 7.0 mmol/l) identified those patients requiring an OGTT to diagnose diabetes. When applied to the UK validation cohort, sensitivity was 97% and specificity 100%. The algorithm was equally effective in the unselected group, aged 59 years (49,68 years) and 54% male, with sensitivity 93% and specificity 100%. HbA1c was 6.0% (5.6,6.6%) and FPG 6.0 mmol/l (5.3,6.8 mmol/l), with 26% having IFG. Use of the algorithm would reduce the number of OGTTs performed in the UK validation cohort by 33% and by 66% in the Australian patients studied. Conclusions, Use of this algorithm would simplify procedures for diagnosis of diabetes and could also be used for monitoring pre-diabetes. Validation is now required in other populations and patient groups. [source] Changing aspirin use in patients with Type 2 diabetes in the UKPDSDIABETIC MEDICINE, Issue 12 2004C. A. Cull Abstract Aims To examine the proportion of UK Prospective Diabetes Study (UKPDS) patients with Type 2 diabetes taking aspirin regularly for the primary and secondary prevention of cardiovascular disease (CVD) before and after publication of the 1997 American Diabetes Association (ADA) Clinical Practice Recommendations and the 1998 Joint British Recommendations on the Prevention of Coronary Disease in Clinical Practice. Methods UKPDS annual review data from 1996/7 (n = 3190) and 2000/1 (n = 2467) were used to determine the prevalence of patients taking aspirin regularly in relation to known CVD risk factors and pre-existing CVD. Results Patients taking aspirin regularly were more often male than female (24 vs. 20%, P = 0.0033), older (66 ± 8 vs. 62 ± 9 years, P < 0.0001) and less often Afro-Caribbean than White Caucasian or Indian Asian (11 vs. 23 vs. 22%, respectively, P < 0.0001). Between 1996/7 and 2000/1 aspirin use in patients without pre-existing CVD increased from 17 to 31% (P < 0.0001) and for those with pre-existing CVD from 76 to 82% (P = 0.032). Conclusion The majority of patients with pre-existing CVD were taking aspirin regularly. Although aspirin use in those without pre-existing CVD approximately doubled after publication of the ADA and Joint British Recommendations, less than two-thirds of these high-risk patients were being treated according to guidelines. This may relate to a lack of convincing evidence for primary CVD prevention or failure to adhere to guidelines. It may be that more trial data is needed to convince clinicians of the value of aspirin therapy in Type 2 diabetes. [source] Differing aspects of insulin resistance in diabetes complications: the shape of things to come.DIABETIC MEDICINE, Issue 12 2002RD Lawrence lecture 2000 Abstract The anticipated global epidemic of diabetes, largely as a consequence of increased rates of obesity, will particularly impact on people of South Asian and African Caribbean descent, two populations at elevated risk of insulin resistance. This article contrasts the consequent heightened risk of heart disease on the one hand in South Asians, and the paradoxical protection from heart disease in African Caribbeans on the other. Protection from the hypertriglyceridaemic effects of insulin resistance is likely to account for much of the African Caribbean paradox, although the mechanisms remain unclear. The growing evidence that insulin resistance is commonly observed in people with Type 1 diabetes, as well as those with Type 2 diabetes, and that features of insulin resistance may play a crucial role in the development of microvascular, as well as macrovascular complications, is also discussed. This indicates novel targets for the prevention and treatment of diabetes complications. Diabet.

DEVANEY Abstract This paper reports on the prevalence of drug use in Asia and the Pacific. It is based on the report "Situational analysis of illicit drug issues and responses in Asia and the Pacific", commissioned by the Australian National Council on Drugs Asia Pacific Drug Issues Committee. Review of existing estimates of the prevalence of people who use illicit drugs from published and unpublished literature and information from key informants and regional institutions was undertaken for the period 1998-2004. Estimates of the prevalence of people who use illicit drugs were conducted for 12 Asian and six Pacific Island countries. The estimated prevalence of those using illicit drugs ranges from less than 0.01% to 4.6%. Countries with estimated prevalence rates higher than 2% are Cambodia, Hong Kong, Philippines, Thailand, Indonesia, Laos and Malaysia. China, Myanmar and Vietnam have estimated prevalence rates ranging between less than 0.01% and 2%. Data to estimate prevalence rates was not available for Pacific Island countries and Brunei. Estimates of the prevalence of drug use are critical to policy development, planning responses and measuring the coverage of programs. However, reliable estimates of the numbers of people using illicit drugs are rare in Asia, particularly the Pacific. [source] From imitation to invention: creating commodities in eighteenth-century BritainECONOMIC HISTORY REVIEW, Issue 1 2002Maxine Berg This article presents the history of new goods in the eighteenth century as a part of the broader history of invention and industrialization. It focuses on product innovation in manufactured commodities as this engages with economic, technological and cultural theories. Recent theories of consumer demand are applied to the invention of commodities in the eighteenth century; special attention is given to the process of imitation in product innovation. The theoretical framework for imitation can be found in evolutionary theories of memetic transmission, in archaeological theories of skeuomorphous, and in eighteenth-century theories of taste and aesthetics. Inventors, projectors, economic policy makers, and commercial and economic writers of the period dwelt upon the invention of new British products. The emulative, imitative context for their invention made British consumer goods the distinctive modern alternatives to earlier Asian and European luxuries. [source] Sexual orientation, substance use behaviors and substance dependence in the United StatesADDICTION, Issue 8 2009Sean Esteban McCabe ABSTRACT Aims To assess past-year prevalence rates of substance use behaviors and substance dependence across three major dimensions of sexual orientation (identity, attraction and behavior) in a large national sample of adult women and men in the United States. Design Data were collected from structured diagnostic face-to-face interviews using the Alcohol Use Disorder and Associated Disabilities Interview Schedule DSM-IV version IV (AUDADIS-IV). Setting Prevalence estimates were based on data collected from the 2004,2005 (wave 2) National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Participants A large national sample of 34 653 adults aged 20 years and older: 52% female, 71% white, 12% Hispanic, 11% African American, 4% Asian and 2% Native American. Findings Approximately 2% of the population self-identified as lesbian, gay or bisexual; 4% reported at least one life-time same-sex sexual partner and 6% reported same-sex sexual attraction. Although non-heterosexual orientation was generally associated with a higher risk of substance use and substance dependence, the majority of sexual minority respondents did not report substance use or meet criteria for DSM-IV substance dependence. There was considerable variation in substance use outcomes across sexual orientation dimensions; these variations were more pronounced among women than among men. Conclusions Results support previous research findings of heightened risk of substance use and substance dependence among some sexual minority groups and point to the need for research that examines the reasons for such differences. Results also highlight important gender differences and question previous findings indicating uniformly higher risk for substance dependence among sexual minorities. Risks appear to vary based on gender and how sexual orientation is defined. Findings have implications for more effective prevention and intervention efforts that target subgroups at greatest risk. [source] Genetic and expression analysis of all non-synonymous single nucleotide polymorphisms in the human deoxyribonuclease I-like 1 and 2 genesELECTROPHORESIS, Issue 12 2010Misuzu Ueki Abstract Members of the human DNase I family, DNase I-like 1 and 2 (DNases 1L1 and 1L2), with physiological role(s) other than those of DNase I, possess three and one non-synonymous SNPs in the genes, respectively. However, only limited population data are available, and the effect of these SNPs on the catalytic activity of the enzyme remains unknown. Genotyping of all the non-synonymous SNPs was performed in three ethnic groups including six different populations using the PCR-RFLP method newly developed. Asian and African groups including Japanese, Koreans, Ghanaians and Ovambos were typed as a single genotype at each SNP, but polymorphism at only SNP V122I in DNase 1L1 was found in Caucasian groups including Germans and Turks; thus a Caucasian-specific allele was identified. The DNase 1L1 and 1L2 genes show relatively low genetic diversity with regard to these non-synonymous SNPs. The level of activity derived from the V122I, Q170H and D227A substituted DNase 1L1 corresponding to SNPs was similar to that of the wild-type, whereas replacement of the Asp residue at position 197 in the DNase 1L2 protein with Ala, corresponding to SNP D197A, reduced its activity greatly. Thus, SNP V122I in DNase 1L1 exhibiting polymorphism exerts no effect on the catalytic activity, and furthermore SNP D197A in DNase 1L2, affecting its catalytic activity, shows no polymorphism. These findings permit us to postulate that the non-synonymous SNPs identified in the DNase 1L1 and 1L2 genes may exert no influence on the activity levels of DNases 1L1 and 1L2 in human populations. [source] Cannabis condemned: the proscription of Indian hempADDICTION, Issue 2 2003Robert Kendell ABSTRACT Aims To find out how cannabis came to be subject to international narcotics legislation. Method Examination of the records of the 1925 League of Nations' Second Opium Conference, of the 1894 Report of the Indian Hemp Drugs Commission and other contemporary documents. Findings Although cannabis (Indian hemp) was not on the agenda of the Second Opium Conference, a claim by the Egyptian delegation that it was as dangerous as opium, and should therefore be subject to the same international controls, was supported by several other countries. No formal evidence was produced and conference delegates had not been briefed about cannabis. The only objections came from Britain and other colonial powers. They did not dispute the claim that cannabis was comparable to opium, but they did want to avoid a commitment to eliminating its use in their Asian and African territories.

[source] Identification of Helicobacter pylori and the cagA genotype in gastric biopsies using highly sensitive real-time PCR as a new diagnostic toolFEMS IMMUNOLOGY & MEDICAL MICROBIOLOGY, Issue 3 2005Shiho Yamazaki Abstract The CagA protein is one of the virulence factors of Helicobacter pylori, and two major subtypes of CagA have been observed, the Western and East Asian type. CagA is injected from the bacteria into gastric epithelial cells, undergoes tyrosine phosphorylation, and binds to Src homology 2 domain-containing protein-tyrosine phosphatase SHP-2. The East Asian type CagA binds to SHP-2 more strongly than the Western type CagA. Here, we tried to distinguish the CagA type by highly sensitive real-time PCR with the objective of establishing a system to detect H. pylori and CagA subtypes from gastric biopsies. We designed primers and probe sets for Western or East Asian- cagA at Western-specific or East Asian-specific sequence regions, respectively, and H. pylori 16S rRNA. We could detect the H. pylori 16S rRNA gene, Western and East Asian- cagA gene from DNA of gastric biopsies. The sensitivity and specificity for H. pylori infection was 100% in this system. In Thai patients, 87.8% (36/41) were cagA -positive; 26.8% (11/41) were Western- cagA positive and 53.7% (22/41) were East Asian- cagA positive, while 7.3% (3/41) reacted with both types of cagA. These results suggest that this real-time PCR system provides a highly sensitive assessment of CagA type as a new diagnostic tool for the pathogenicity of H. pylori infection. [source] An evaluation of the potential influence of SST and currents on the oceanic migration of juvenile and immature chum salmon (Oncorhynchus keta) by a simulation modelFISHERIES OCEANOGRAPHY, Issue 1 2004Tomonori Azumaya Abstract Using a salmon migration model based on the assumption that swimming orientation is temperature dependent, we investigated the determining factors of the migration of juvenile and immature chum salmon (Oncorhynchus keta) in the North Pacific. We compared the predictions of the model with catch data of immature and juvenile chum salmon collected by Japanese research vessels from 1972 to 1999. The salmon migration model reproduced the observed distributions of immature chum salmon and indicates that passive transport by wind-driven and geostrophic currents plays an important role in the eastward migration of Asian salmon. These factors result in a non-symmetric distribution of Asian and North American chum salmon in the open ocean. The directional swimming component contributes to the northward migration in summer. The model results indicate that during the first winter Asian chum salmon swim northward against the southward wind-driven currents to stay in the western North Pacific. This suggests that Asian chum salmon require more energy to migrate than other stocks during the first winter of their ocean life.

Wan Jr. Rent-seeking; industrialization; Korea; regulatory reform Abstract. Before the reform in the 1960s, twin vicious circles perpetuated the shortages of foreign exchange and labor skill, and prevented the Korean economy from realizing its considerable growth potential. The breakthrough came when the Japanese labor shortage facilitated Korean exports, after economic normalization between the two countries. The reformed institutions reduced rent-seeking and refocused Korean managerial efforts to pioneering activities. The Korean takeoff scenario is a shared theme among all four Asian newly industrialized economies cited by Lucas (1988) as showcases. [source] Differences in the process of diabetic care between south Asian and white patients in inner-city practices in Nottingham, UKHEALTH & SOCIAL CARE IN THE COMMUNITY, Issue 3 2004Christopher David BM BS MRCGP Abstract The prevalence and complication rate of diabetes is higher amongst British south Asians when compared to the rest of the adult population. There is some evidence to suggest that there are differences in access to healthcare in the UK for different ethnic groups, but there has been little research examining differences in processes of care between ethnic groups and place of delivery of diabetic care. The present study was a retrospective, multi-practice audit exploring differences in the processes of diabetic care provided to white and south Asian patients. Data were obtained from eight practices located in deprived areas in Nottingham, UK. A review of the evidence-based protocols for the monitoring of diabetic care generated a list of process criteria to be measured. All primary care data sources were examined over a 12-month period by a single investigator. The data were analysed with respect to patient ethnicity and place of diabetic care after adjusting for confounders. Eight hundred and thirty-nine diabetic patients were included in the audit and 671 (80.0%) received a formal annual diabetic review. One hundred and five (12.5%) patients were classified as south Asian. They were significantly less likely to have their blood pressure [86% versus 89%, odds ratio (OR) = 0.62, 95% confidence interval (95% CI) = 0.54,0.72] or serum creatinine (67% versus 76%, OR = 0.41, 95% CI = 0.32,0.52) measured when compared to white patients. Patients receiving shared care from a hospital-based diabetic team were more likely to have a range of items of the annual review recorded. When examined by ethnicity, south Asians receiving shared care were again less likely than white patients to have their blood pressure and serum creatinine measured. There was also some evidence that they may be less likely to have their body mass index recorded and their feet examined. The findings of the present study showed that, although most diabetic patients received a formal annual clinical review, scope for improvement remained. Shared care of patients with a hospital-based team produced better results when processes of care were examined. However, this benefit did not apply equally to south Asian and white patients. Further studies are indicated to confirm these results, which may have wider implications for the planning and provision of diabetic care. [source] Molecular Epidemiology and Outcome of Helicobacter pylori Infection in Thailand: a Cultural Cross RoadsHELICOBACTER, Issue 5 2004Ratha-Korn Vilaichone ABSTRACT Background., Thailand is at the cultural cross roads between East and South Asia. It has been suggested that this is also the region where the predominant Helicobacter pylori (H. pylori) genotype changes from East Asian to South Asian. Methods., We compared the molecular epidemiology and outcome of H. pylori infections among different ethnic groups in Thailand (Thai, Thai-Chinese and Chinese). H. pylori isolates were genotyped by polymerase chain reaction based on cagA, cag right end junction and vacA genotypes. Results., Ninety-eight isolates from 38 ethnic Thai, 20 ethnic Chinese and 40 Thai-Chinese were categorized into East Asian (45%), South/Central Asian (26%), Western (1%) or mixed type (29%). The East Asian genotype was the most common among Chinese (85%) and Thai-Chinese (55%) (p < .01 compared to ethnic Thai). The ethnicity of the mother among mixed Thai-Chinese marriages predicted the genotype of the child's H. pylori (e.g. when the mother was Chinese, 84% had East Asian type vs. 29% when the mother was Thai) (p < .001). Gastric cancer was common among ethnic Chinese with East Asian genotype (e.g. all Chinese with gastric cancer or peptic ulcer disease had East Asian genotype, whereas only 40% of Chinese with gastritis had this genotype). Conclusions., Immigration, intermarriage and the variety of H. pylori genotypes in Thailand suggest that Thailand is an ideal site for epidemiological studies attempting to relate H. pylori genotypes and host factors to outcome. Our data also support the hypothesis that the primary caretaker of the children is most likely the source of the infection. [source] Long-term efficacy and safety of adefovir dipivoxil for the treatment of hepatitis B e antigen,positive chronic hepatitis B,HEPATOLOGY, Issue 3 2008Patrick Marcellin Treatment of 171 patients with hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) with adefovir dipivoxil (ADV) 10 mg over 48 weeks resulted in significant histological, virological, serological, and biochemical improvement compared with placebo. The long-term efficacy and safety of ADV in a subset of these patients was investigated for up to 5 years. Sixty-five patients given ADV 10 mg in year 1 elected to continue in a long-term safety and efficacy study (LTSES). At enrollment, the 65 LTSES patients were a median 34 years old, 83% male, 74% Asian, 23% Caucasian, median baseline serum hepatitis B virus (HBV) DNA 8.45 log10 copies/mL, and median baseline alanine aminotransferase (ALT) 2.0 × upper limit of normal. At 5 years on study, the median changes from baseline in serum HBV DNA and ALT for the 41 patients still on ADV were 4.05 log10 copies/mL and ,50 U/L, respectively. HBeAg loss and seroconversion were observed in 58% and 48% of patients by end of study, respectively. Fifteen patients had baseline and end of follow-up liver biopsies; improvements in necroinflammation and fibrosis were seen in 67% and 60% of these patients, respectively. Adefovir resistance mutations A181V or N236T developed in 13 LTSES patients; the first observation was at study week 195. There were no serious adverse events related to ADV. Conclusion: Treatment with ADV beyond 48 weeks was well tolerated and produced long-term virological, biochemical, serological, and histological improvement. (HEPATOLOGY 2008;48:750,758.)

Toan Eight genotypes (A-H) of hepatitis B virus (HBV) have been identified. However, the impact of different genotypes on the clinical course of hepatitis B infection remains controversial. We investigated the frequency and clinical outcome of HBV genotypes and genotype mixtures in HBV-infected patients from Vietnam, Europe, and Africa. In addition, we analyzed the effects of genotype mixtures on alterations in in vitro viral replication. In Asian patients, seven genotypes (A-G) were detected, with A, C, and D predominating. In European and African patients, only genotypes A, C, D, and G were identified. Genotype mixtures were more frequently encountered in African than in Asian (P = .01) and European patients (P = .06). In Asian patients, the predominant genotype mixtures included A/C and C/D, compared to C/D in European and A/D in African patients. Genotype A was more frequent in asymptomatic compared with symptomatic patients (P < .0001). Genotype C was more frequent in patients with hepatocellular carcinoma (HCC; P = .02). Genotype mixtures were more frequently encountered in patients with chronic hepatitis in comparison to patients with acute hepatitis B (P = .015), liver cirrhosis (P = .013), and HCC (P = .002). Viral loads in patients infected with genotype mixtures were significantly higher in comparison to patients with a single genotype (P = .019). Genotype mixtures were also associated with increased in vitro HBV replication. In conclusion, infection with mixtures of HBV genotypes is frequent in Asia, Africa, and Europe. Differences in the replication-phenotype of single genotypes compared to genotype-mixtures suggest that co-infection with different HBV-genotypes is associated with altered pathogenesis and clinical outcome.

Nguyen ,-Fetoprotein (AFP) is frequently used as a diagnostic marker for hepatocellular carcinoma (HCC). Most available data concerning AFP come from studies of patients with chronic hepatitis B or other chronic liver diseases of mixed etiologies. Limited data concerning the diagnostic value of AFP for hepatitis C virus (HCV)-related HCC have to date come only from Asian and European studies, and results are conflicting. There may be significant differences in AFP levels depending on racial backgrounds and etiologies of primary liver disease. We conducted a multicenter, retrospective, case-control study of 163 HCC patients with HCV infection and 149 control patients with HCV-related cirrhosis. The positive likelihood ratios for AFP at 0 to 20, 21 to 50, 51 to 100, and 101 to 200 ng/mL were 0.46, 1.31, 1.15, and 6.90, respectively. No controls had AFP greater than 200 ng/mL. The sensitivity of AFP for the diagnosis of HCC in African Americans with HCV infection was lower than that of patients of all other ethnic groups combined (57.1% vs. 81.6% for AFP > 10 ng/mL, P = .02, and 42.9% vs. 66.0% for AFP > 20 ng/mL, P = .05). The area under the receiver operating characteristics curve was 0.81 for non-African Americans but only 0.56 for African Americans. In conclusion, AFP greater than 200 ng/mL can be used to confirm HCC in patients with HCV-related cirrhosis and a hepatic mass. However, AFP is insensitive for the diagnosis of HCC in African Americans. [source] Rethinking Kashmir's History from a Borderlands PerspectiveHISTORY COMPASS (ELECTRONIC), Issue 7 2010Chitralekha Zutshi Although borders haunt its historical and recent past as well as its contemporary political situation, Kashmir has rarely been theorized as a borderland. This article examines the perspective of borderlands as conceptualized in North American, Asian and African borderlands scholarship. It argues that the application of this perspective , in which borderlands are defined as middle grounds where imperial competition and negotiations among a variety of imperial and indigenous actors led to the production of distinct political cultures , to rethinking Kashmir's history has the potential to liberate the region from the imperatives of national borders that misread its history, while also reinvigorating South Asian borderlands scholarship. [source] Increased risk of early virological failure in non-European HIV-1-infected patients in a Dutch cohort on highly active antiretroviral therapyHIV MEDICINE, Issue 5 2005JB Van Den Berg Objective To compare early and late responses to highly active antiretroviral therapy (HAART) in European and non-European HIV-1 infected patients in a Dutch cohort. Methods We retrospectively analysed the response to HAART of 216 previously treatment-naive HIV-1-infected patients using the University Medical Centre Utrecht HIV database. African (n=51), Asian (n=7), and Central/South American (n=6) patients were classified as non-European, and others as European (n=152). Early failure was defined as a viral load that remained above 400 HIV-1 RNA copies/mL after 6 months of treatment with HAART. Late-phase failure was determined in patients who were successfully treated in the early phase and was defined as two consecutive viral load measurements above 400 copies/mL, a new AIDS-defining event or death. Results In the early phase, four of 152 (2.6%) European and eight of 64 (12.5%) non-European patients failed HAART. A significant increased risk of virological failure in the early phase of treatment was observed for non-Europeans as compared to Europeans (odds ratio 4.6; 95% confidence interval 1.1,20.2). Low serum drug levels in the absence of resistant virus were often seen at the time of early failure. No difference in late-phase failure was observed between the two groups (adjusted hazard ratio 0.6; 95% confidence interval 0.3,1.2). Conclusions Non-European patients had a 4.6 times higher risk of virological failure than their European counterparts in the first 6 months of treatment with HAART. This failure seemed to be associated with low serum drug levels at the time of failure. However, if HAART was successful in the early phase, response rates in the late phase were similar for Europeans and non-Europeans. [source] Pyrosequencing for detection of mutations in the connexin 26 (GJB2) and mitochondrial 12S RNA (MTRNR1) genes associated with hereditary hearing loss,HUMAN MUTATION, Issue 4 2002Alessandro Ferraris Abstract Hereditary hearing loss (HHL) is one of the most common congenital disorders and is highly heterogeneous. Mutations in the connexin 26 (CX26) gene (GJB2) account for about 20% of all cases of childhood deafness, and approach 50% in documented recessive cases of non-syndromic hearing loss. In addition, a single mitochondrial DNA mutation, mt1555A>G, in the 12S rRNA gene (MTRNR1), is associated with familial cases of progressive deafness. Effective screening of populations for HHL necessitates rapid assessment of several of these potential mutation sites. Pyrosequencing links a DNA synthesis protocol for determining sequence to an enzyme cascade that generates light whenever pyrophosphate is released during primer strand elongation. We assessed the ability of Pyrosequencing to detect common mutations causing HHL. Detection of the most common CX26 mutations in individuals of Caucasian (35delG), Ashkenazi (167delT), and Asian (235delC, V37I) descent was confirmed by Pyrosequencing. A total of 41 different mutations in the CX26 gene and the mitochondrial mt1555A>G mutation were confirmed. Genotyping of up to six different adjacent mutations was achieved, including simultaneous detection of 35delG and 167delT. Accurate and reproducible results were achieved taking advantage of assay flexibility and experimental conditions easily optimized for a high degree of standardization and cost-effectiveness. The standardized sample preparation steps, including target amplification by PCR and preparation of single-stranded template combined with automated sequence reaction and automated genotype scoring, positions this approach as a potentially high throughput platform for SNP/mutation genotyping in a clinical laboratory setting.

[source] Metabolic differences between Asian and Caucasian patients on clozapine treatmentHUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 4 2007Mythily Subramaniam Abstract Objective To establish if there are ethnic differences in the various metabolic disturbances that are common with clozapine treatment. Method Forty subjects (20 Asians and 20 Caucasians) with a diagnosis of schizophrenia were recruited for the study. Clozapine blood levels as well as fasting blood glucose, lipid levels, and liver function tests were established. Other clinical parameters such as blood pressure and Body Mass Index (BMI) were recorded for each patient. Results The mean clozapine dose was significantly higher in the Caucasian subjects (432.5,±,194.7,mg) as compared to the Asian subjects (175.6,±,106.9,mg) (p,<,0.001) while the mean weight-corrected dose for Asian patients was lower (3.0,±,1.9 and 5.0,±,2.1,mg/kg, respectively, p,=,0.005). There were, however, no ethnic differences in the mean plasma clozapine concentration (415.3,±,185.8,ng/ml in Caucasians and 417.1,±,290.8,ng/ml in Asians). BMI were significantly higher in Caucasians, as were the number of subjects with hypertension; levels of hepatic enzymes were higher in the Asian group. Conclusions Not only are there pharmacokinetic differences between Asian and Caucasian patients receiving clozapine, but there may also be differential emergence of certain metabolic abnormalities like hypertension and weight gain in these two ethnic groups. However, the effects of life style including diet and exercise cannot be excluded. Copyright © 2007 John Wiley & Sons, Ltd. [source] Plumage-based phylogenetic analyses of the Merops bee-eatersIBIS, Issue 3 2004D. BRENT BURT I review previous systematic work on the family Meropidae and present phylogenetic hypotheses derived from my analyses of colour, pattern and shape variation in 30 plumage regions among species and subspecies in this family. Consistent patterns are seen across shallow portions of the trees. Uncertainty remains concerning the placement of several deep branches within this group's phylogeny. In particular, the phylogenetic placement of Meropogon forsteni and Merops breweri, M. ornatus, M. hirundineus and M. boehmi remains uncertain. The biogeographical patterns in the resultant trees are similar with either a Southeast Asian or African origin for the family, with most of the early diversification occurring in Africa, and with multiple independent subsequent invasions of non-African areas.
