Do lugar de fala ao corpo como lugar de diálogo: raça e etnicidades numa perspectiva comunicacional / From the standpoint of speech to the body as locus of dialogue: race and ethnicities from a communicational perspective / Desde el locus social de quien habla al cuerpo como espacio de diálogo: raza y etnicidades en una perspectiva referente a la comunicación

"Eu sou um pessimista ativo, porque tenho fé". Assim Muniz Sodré se declara ao conceder à Reciis uma entrevista que trata sobre a questão de raça/etnicidades em articulação com os estudos da comunicação. O professor e pesquisador argumenta que a escravidão está enraizada na forma social brasileira, pois a abolição jurídico-política não foi suficiente para abolir os espíritos escravocratas. Mas que é preciso ter fé nas movimentações e contramovimentações sensíveis do corpo do outro, negro, o qual mobiliza as barreiras de imunidade racistas. Sodré entende que a expressão lugar de fala é uma reivindicação efêmera, pois acredita na virtude do corpo como um espaço de diálogo com outros lugares. Em relação aos estudos de comunicação e raça, argumenta que as pesquisas se restringem ainda às descrições das tecnologias da mídia, assim como as pesquisas de maneira geral, mas que esses estudos "têm um papel político forte: eles fazem emergir essa classe intelectual negra que estava submersa". Muniz Sodré é professor emérito da Universidade Federal do Rio de Janeiro.

Differences in survival by race/ethnicity among cutaneous melanoma patients in the United States over a period from 1982 to 2011

Background: Melanoma is an aggressive skin cancer with a high mortality rate. The incidence of melanoma has increased in recent years from 1:1500 in 1935 to 1:50 in 2011. The aim of this study is to investigate survival by race/ethnicity, taking site into account, among melanoma patients in the United States.Methods: This study is a secondary analysis of the Surveillance, Epidemiology, and End Results (SEER) Program. SEER collects data through a non-concurrent cohort study design. The sample size was 185219 participants. The chi-square test was used to examine the association between categorical variables. Kaplan-Meier survival analysis was used to estimate the overall survival curve and to estimate the survival curve per race/ethnicity. Collinearity was assessed using Pearson correlation. Cox proportional hazards regression was used to calculate the unadjusted and adjusted hazard ratios (HR).Results: Non-Hispanic White (NHW) and Other patients were older in age (70 years or older), while non-Hispanic Black (NHB) and Hispanic patients were younger (30-39 years). Melanoma in NHW patients was mostly located in trunk whereas melanoma for NHB, Hispanic and Other patients was mostly located in the lower limbs. For all races/ethnicities except for NHB, more individuals were diagnosed between 2002 and 2011. Patients with melanoma in upper limbs lived more frequently. Fewer women died (6.8%) compared to men (17.1%). Patients who were diagnosed between the ages of 30-39 were more likely to die. NHB had an adjusted HR of 3 (95% CI 2.7, 3.3) compared to NHW. The adjusted HR of lower limb was 1.6 (95% CI 1.5, 1,6) compared to the reference group (Head and Neck). The hazard for trunk and lower limb were about the same as the reference. Those who were 70 years or older had an adjusted HR of 2.2 (95% CI 2.0, 2.4). Women had an adjusted HR of 0.4 (95% CI 0.4, 0.5), and diagnosis during the decade 1982-1991 had an adjusted HR of 2.6 (95% CI 2.4, 2.7).Conclusions: NHB patients and patients of ages 30-39 years were more likely to die. The poorest survival was for diagnosis between 1982 and 1991. However, more individuals were diagnosed between 2002 and 2011. The lower limb had a worse prognosis with adjusted HR of 1.6 (95% CI 1.5, 1,6), and more men were diagnosed than women.

Kidd Phenotypes in Multiple Ethnicities in Hospital Umum Sarawak, Malaysia

@#Introduction: Kidd blood group system is distributed differently within populations. In Malaysia, the prevalence of Kidd phenotypes have been reported but not in Hospital Umum Sarawak (HUS).We characterised Kidd phenotypes among regular blood donors in HUS. Methods: A cross-sectional study was done from 1st September 2015 to 10th September 2015. Blood samples were collected from 250 regular blood donors of different ethnicities in HUS. Samples were then investigated for Kidd blood group phenotypes by utilising Seraclon anti-Jka and anti-Jkb reagents employing the Diamed-ID gel card system. Results: Phenotype Jk(a+b+) was found in 110 out of 250 (44.0%) and phenotype Jk (a-b-) phenotype in seven out of 250 (2.8%) blood donors. Jk(a+b-) was detected in 60 out of 250 (24.0%) and Jk(a-b+) in 73 out of 250 (29.2%) donors. Kidd phenotype was detected in four ethnics; Chinese 50.8%, Malays 38.4%, Bidayuh 10.0% and Iban 0.8%. Jk(a-b-) phenotype was present only in the Malays; seven out of 250 (2.8%) but not found in other ethnicities. Conclusion: Jk(a+b+) is the most common Kidd phenotype found in regular blood donors in HUS in the four ethnicities studied. Only Malays exhibit the Jk(a-b-) phenotype which is a rare phenotype. The results of this study may serve as a preliminary database for Kidd blood group profile of regular blood donors in HUS.

The Mutation Analysis of Common Deafness Genes Using SNPscan Technology in Nonsyndromic Hearing Loss Patients of Minority Ethnicities in Qinghai Province / 听力学及言语疾病杂志

Objective This study aims to investigate the mutation spectrum and frequency of GJB2 , mtDNA12SrRNA,and SLC26A4 genes in Hui people,Tibetan,Tu nationality,and Mongolian patients with non-syndromic hearing loss in Qinghai province.Methods Peripheral blood samples were obtained from a total of 211 minority patients with nonsyndromic hearing loss in Qinghai province to extract genomic DNA.Three genes of GJB2,mitochondrialDNA12SrRNA,and SLC26A4 were screened for mutations in our study cohort using SNPscan technology.Results Among these 211 patients,5 Tu patients and 1 Mongolian patient were found to carry the ho-moplasmic mtDNAA1555G mutation.The GJB2 mutations detection rates were 11.38%,4.55%,5.88%,and 10%in Hui people,Tibetan,Tu nationality,and Mongolian patients,respectively.No statistically significant differences in the GJB2 mutations detection rates were found among all four ethnicities (P>0.05).c.235delC was the most prevalent mutation in both Tu patients and Mongolian patients.The allele frequency was 2.94% and 5%,respec-tively.While for Hui patients,c.299 300delAT was the most prevalent mutation with the allele frequency of 4.47%.The mutations detection rates of SLC26A4 were 6.5%,4.55%and 2.94%in Hui people,Tibetan,and Tu nationality patients,respectively.No statistically significant differences in the SLC26A4 mutations detection rates were found among all three ethnicities (P>0.05).c.235delC was the most prevalent mutation in Hui patients,the allele frequency was 2.44%.While for Tibetan patients,c.1226G>A was the most prevalent mutation with allele frequency of 2.27%.Conclusion A total of 10.9% of deaf patients have inherited hearing impairment caused by GJB2,SLC26A4,and mtDNAA1555G mutations.The mutation spectrum of GJB2 and SLC26A4 genes has the eth-nic specificity in nonsyndromic hearing loss patients of minority ethnicities in Qinghai province.

Research on Intracranial Atherosclerosis from the East and West: Why Are the Results Different? / 대한뇌졸중학회지

Intracranial atherosclerosis (ICAS) is a major cause of stroke worldwide and is more common in Asians than Caucasians. The study results from the East and West are generally similar, but notable differences exist. For example, studies from the East have reported that ICAS is associated with young age, whereas ICAS seems to be associated with old age in the West. Studies from the East have strongly suggested that mild ICAS associated with branch occlusion is one of the main causes of single subcortical infarction, whereas this aspect has not been considered in stroke classification systems developed in the West. While clopidogrel is commonly used in patients with large artery disease in the West, cilostazol has been more extensively studied and commonly used in ICAS patients in the East. A randomized controlled study from the West reported negative results regarding the efficacy of stenting in ICAS patients due largely to a relatively high rate of periprocedural adverse events, whereas research papers from the East have reported a relatively lower rate of complications. Studies to narrow these East-West gaps should be performed, including risk factor studies using homogenous ethnic populations, studies investigating appropriate classification systems, drug trials in different ethnic populations, and rigorous high standard randomized controlled studies on the efficacy of stenting in Eastern populations.

Superoxide dismutase, catalase, glutathione peroxidase and gluthatione S-transferases M1 and T1 gene polymorphisms in three Brazilian population groups

Antioxidants such as superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX1) reduce the oxidation rates in the organism. Gluthatione S-transferases (GSTs) play a vital role in phase 2 of biotransformation of many substances. Variation in the expression of these enzymes suggests individual differences for the degree of antioxidant protection and geographical differences in the distribution of these variants. We described the distribution frequency of CAT (21A/T), SOD2 (Ala9Val), GPX1 (Pro198Leu), GSTM1 and GSTT1 polymorphisms in three Brazilian population groups: Kayabi Amerindians (n = 60), Kalunga Afro-descendants (n = 72), and an urban mixed population from Federal District (n = 162). Frequencies of the variants observed in Kalunga (18 percent to 58 percent) and Federal District (33 percent to 63 percent) were similar to those observed in Euro and Afro-descendants, while in Kayabi (3 percent to 68 percent), depending on the marker, frequencies were similar to the ones found in different ethnic groups. Except for SOD2 in all population groups studied here, and for GPX1 in Kalunga, the genotypic distributions were in accordance with Hardy-Weinberg Equilibrium. These data can clarify the contribution of different ethnicities in the formation of mixed populations, such as that of Brazil. Moreover, outcomes will be valuable resources for future functional studies and for genetic studies in specific populations. If these studies are designed to comprehensively explore the role of these genetic polymorphisms in the etiology of human diseases they may help to prevent inconsistent genotype-phenotype associations in pharmacogenetic studies.

Iranian human genome project: Overview of a research process among Iranian ethnicities.

The Human Genome Project (HGP) refers to the international scientific research program, formally begun in October 1990 and completed in 2003, mainly designated to discover all the human genes, analyzing the structure of human DNA and determining the location of all human genes and also making them accessible for further biological and medical investigations. With the appropriate rationale approach, a similar study has been held in Iran. The study of human genome among Iranian ethnicities (IHGP) has been attempted formally in 2000 through a detailed and fully programmed research among all the major ethnic groups by more than 1,900 samples from all over Iran based on the main demographical and anthropological findings and formally known criteria considered for the international HGP. This paper overviewed the process of the research in the terms of program goals, primary data collection, research designation and methodology and also practical aspects and primary findings of the Iranian genome project and its progress during a nearly 5-year period.

Haptoglobin gene subtypes in three Brazilian population groups of different ethnicities

Haptoglobin is a plasma hemoglobin-binding protein that limits iron loss during normal erythrocyte turnover and hemolysis, thereby preventing oxidative damage mediated by iron excess in the circulation. Haptoglobin polymorphism in humans, characterized by the Hp*1 and Hp*2 alleles, results in distinct phenotypes known as Hp1-1, Hp2-1 and Hp2-2, whose frequencies vary according to the ethnic origin of the population. The Hp*1 allele has two subtypes, Hp*1F and Hp*1S, that also vary in their frequencies among populations worldwide. In this work, we examined the distribution frequencies of haptoglobin subtypes in three Brazilian population groups of different ethnicities. The haptoglobin genotypes of Kayabi Amerindians (n = 56), Kalunga Afro-descendants (n = 70) and an urban population (n = 132) were determined by allele-specific PCR. The Hp*1F allele frequency was highest in Kalunga (29.3 percent) and lowest in Kayabi (2.6 percent). The Hp*1F/Hp*1S allele frequency ratios were 0.6, 1.0 and 0.26 for the Kayabi, Kalunga and urban populations, respectively. This variation was attributable largely to the Hp*1F allele. However, despite the large variation in Hp*1F frequencies, results of FST (0.0291) indicated slight genetic differentiation among subpopulations of the general Brazilian population studied here. This is the first Brazilian report of variations in the Hp *1F and Hp*1S frequencies among non-Amerindian Brazilians.
