Lipid profile disturbances are highly prevalent in Japanese-Brazilians

Alta prevalência de diabetes em população nipo-brasileira de Bauru/SP foi previamente relatada. Visando a complementar a avaliação do risco cardiometabólico, este estudo analisou distúrbios no perfil lipídico de 1.330 nipo-brasileiros (46% homens) > 30 anos. Definiu-se hipercolesterolemia por níveis de colesterol total > 240 mg/dL; hipertrigliceridemia por valores > 150 mg/dL e HDL-colesterol baixo por valores < 40 mg/dL e < 50 mg/dL para homens e mulheres, respectivamente. A prevalência desses distúrbios foi comparada pelo qui-quadrado, estratificando-se por sexos e categorias glicêmicas. As médias dos lipídeos e lipoproteínas foram comparadas entre sexos pelo teste t de Student. A prevalência de hipertrigliceridemia foi de 66,0% (IC95%:63,5 - 68,5%), sendo mais comum em homens e aumentando com a piora da categoria glicêmica; a trigliceridemia média foi 235,7 &plusmn; 196,3 mg/dL. A prevalência de hipercolesterolemia foi 24,4% (IC95%:22,1 - 26,7%); HDL-C baixo foi observado em 43,0% (IC95%:39,4 - 46,6%] das mulheres e 17,5% (IC95%:14,5 - 20,5%) dos homens, porém a razão colesterol total/HDL-C foi menor em mulheres (4,23 &plusmn; 0,68 vs. 4,40 &plusmn; 0,73; p < 0,001). Em nipo-brasileiros, a hipertrigliceridemia é a anormalidade lipídica mais comum, em concordância com a elevada prevalência de diabetes. Os homens apresentaram pior perfil lipídico que as mulheres. Sugere-se que hábitos de vida ocidental possam estar deteriorando a saúde desses indivíduos.High prevalence of diabetes has been previously reported in Japanese-Brazilians. In an attempt to better estimate the cardiometabolic risk, this study evaluated lipid disorders in 1,330 Japanese-Brazilians (46% men) aged >30 years. Hypercholesterolemia was defined as serum cholesterol > 240 mg/dL, hypertriglyceridemia as values > 150 mg/dL and low-HDL-C as values <40 mg/dL and <50 mg/dl for men and women respectively. The prevalence of dyslipidemias was compared by the chi-square test between gender and glycemic category. Mean and Standard Deviation of lipids and lipoproteins were compared by the Student t-Test between gender. Hypertriglyceridemia was detected in 66.0% [95% CI: 63.5-68.5] of the population, being more common in men and increasing with deterioration of glucose metabolism. Mean level of triglycerides was 235.7&plusmn;196.3 mg/dL. The prevalence of hypercholesterolemia was 24.4% [95% CI: 22.1- 26.7]. Low HDL-C was observed in 17.5% [95% CI: 14.5-20.5] of men and 43.0% [95% CI: 39.4- 46.6] of women but total / HDL-cholesterol ratio was lower in women (4.23 &plusmn; 0.68 vs. 4.40 &plusmn; 0.73, p<0.001). In Japanese-Brazilians, hypertriglyceridemia is the commonest dyslipidemia, in agreement with the high prevalence of diabetes. Men showed a worse lipid profile than women; it was suggested that the Western diet and living habits could be deteriorating their health.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP

Stress modulation as a means to improve yeasts for lignocellulose bioconversion

The second-generation (2G) fermentation environment for lignocellulose conversion presents unique challenges to the fermentative organism that do not necessarily exist in other industrial fermentations. While extreme osmotic, heat, and nutrient starvation stresses are observed in sugar- and starch-based fermentation environments, additional pre-treatment-derived inhibitor stress, potentially exacerbated by stresses such as pH and product tolerance, exist in the 2G environment. Furthermore, in a consolidated bioprocessing (CBP) context, the organism is also challenged to secrete enzymes that may themselves lead to unfolded protein response and other stresses. This review will discuss responses of the yeast Saccharomyces cerevisiae to 2G-specific stresses and stress modulation strategies that can be followed to improve yeasts for this application. We also explore published –omics data and discuss relevant rational engineering, reverse engineering, and adaptation strategies, with the view of identifying genes or alleles that will make positive contributions to the overall robustness of 2G industrial strains
