Homocysteine and Cardiovascular Risk Factors in Overweight or Obese Children and Adolescents

Introduction: Among the extrinsic factors, homocysteine (Hy) stands out, which is an intermediate amino acid of the intracellular metabolism of methionine involved in the process of cellular oxidation, which promotes the installation of atheromatous plaques and, therefore, is considered as an emerging cardiovascular risk factor. Objective: To evaluate the plasma homocysteine levels (Hy) in overweight or obese children and adolescents and their relation with cardiovascular risk factors. Methods: A cross-sectional study was conducted from July 2011 to May 2012 with overweight or obesity children and adolescents aged 2 to 18 years followed at the Center for Childhood Obesity (IOC), Campina Grande-PB. A structured form was used to record demographic, socioeconomic and clinics variables and the patients underwent laboratory tests to define their lipid and glucose profiles and measurement of plasma Hy levels. Results: The study evaluated a total of 165 children and adolescents with mean age of 12.5 (±2.5) years;the majority were female (57.0%). Regarding the lipid profile, there was more individuals with low HDL cholesterol (88.5%). Plasma Hy levels were high in 24.2% of the sample. The mean Hy levels ranged from 4.3 to 18.9 μmol/L, being higher in males, obese adolescents and also in patients with high insulin levels and resistance. Conclusions: The results shown in this study emphasize the importance of detecting and controlling the plasma Hy levels as an independent cardiovascular risk factor, and the need for further studies to evaluate the clinical and biological factors related to alterations in its metabolism.

Background： Beef cattle breeding programs in Brazil have placed greater emphasis on the genomic study of reproductive traits of males and females due to their economic importance. In this study, genome-wide associations were assessed for scrotal circumference at 210 d of age, scrotal circumference at 420 d of age, age at first calving, and age at second calving, in Canchim beef cattle. data quality control was conducted resulting in 672,778 SNPs and 392 ***： Associated SNPs were observed for scrotal circumference at 420 d of age（435 SNPs）, followed by scrotal circumference at 210 d of age（12 SNPs）, age at first calving（six SNPs）, and age at second calving（four SNPs）. We investigated whether significant SNPs were within genic or surrounding regions. Biological processes of genes were associated with immune system, multicellular organismal process, response to stimulus, apoptotic process, cellular component organization or biogenesis, biological adhesion, and ***： Few associations were observed for scrotal circumference at 210 d of age, age at first calving, and age at second calving, reinforcing their polygenic inheritance and the complexity of understanding the genetic architecture of reproductive traits. Finding many associations for scrotal circumference at 420 d of age in various regions of the Canchim genome also reveals the difficulty of targeting specific candidate genes that could act on fertility; nonetheless,the high linkage disequilibrium between loci herein estimated could aid to overcome this issue. Therefore, al relevant information about genomic regions influencing reproductive traits may contribute to target candidate genes for further investigation of causal mutations and aid in future genomic studies in Canchim cattle to improve the breeding program.

在环保法规和消费者意识的推动下,生物基涂料市场正在迅速发展壮大,但仍有一些障碍需要克服。Clariant、Spolchemie和IVM Chemicals等公司的行业专家分享了他们对此的见解。Markets and Markets公司认为,2022年生物基涂料市场价值为105亿欧元,预计将以9.5%的复合年增长率增长,到2027年达到166亿欧元(见图1)。该市场发展迅速,但制造商仍认为需求疲软。据Spolchemie公司的Kamila Vítek Derynková估计,生物基涂料的市场份额不到10%。在树脂行业中,生物基产品的比例“可能占5%左右,甚至更低,但预计未来几年中会取得进一步增长——这主要是由于环境友好和用户友好解决方案重要性的日益上升”。
