A Nutrigenetic approach to examine the relationship between vitamin B12 status and cardio-metabolic traits in multiple ethnic groups – findings from the GeNuIne Collaboration
Low vitamin B12 concentrations have been shown to be risk factors for metabolic traits in numerous observational studies; however, the relationship has remained inconsistent. It is possible that certain genotypes jointly contribute to obesity and vitamin B12 deficiency, and these may be modulated by dietary factors. The main objective of this review article was to summarize the effect of gene-nutrient interactions on vitamin B12 concentrations and cardio-metabolic disease risk factors using population-based studies from different ethnic groups from the GeNuIne (Gene-Nutrient Interactions) Collaboration. Interactions between vitamin B12-related SNPs and protein energy intake (%) on waist circumference (Pinteration=0.002) and body fat percentage (Pinteraction=0.034), were observed in Sri Lankan and Indonesian populations, respectively. In the study in Brazilian adolescents, the metabolic and vitamin B12 related SNPs showed a significant interaction with carbohydrate and protein intakes on oxidised low density lipoprotein cholesterol and homocysteine concentrations, respectively. In the Asian Indian population, an association between obesity-related SNPs and vitamin B12 concentrations (P = 0.018) was observed. In summary, these studies in multiple ethnic groups show that the association between genetically low vitamin B12 concentrations and metabolic outcomes may be modified by dietary intake. Further studies utilising larger sample sizes are needed to confirm or refute our findings

Aldehydes: Magnificent acyl equivalents for direct acylation
From the viewpoint of meeting the current green chemistry challenges in chemical synthesis, there is a need to disseminate how the cocktail of acylation and activation can play a pivotal role in affording bioactive acylated products comprising substituted ketone motifs in fewer reaction steps, with higher atom-economy and improved selectivity. In recent years, a significant number of articles employing the title compounds "aldehydes"as magnificent acylation surrogates which are less toxic and widely applicable have been published. This review sheds light on the compounds use for selective acylation of arene, heteroarene and alkyl (sp3, sp2 and sp) C-H bonds by proficient utilization of the C-H activation strategy. Critical insights into selective acylation of diverse moieties for the synthesis of bioactive compounds are presented in this review that will enable academic and industrial researchers to understand the mechanistic aspects involved and fruitfully employ these strategies in designing novel molecules. © The Royal Society of Chemistry
New insights on low vitamin D plasma concentration as a potential cardiovascular risk factor
The role of Vitamin D hormone in human health and disease is still debated. Recently, growing attention has been paid to its putative role in cardiovascular system homeostasis with several studies that suggested a correlation between low vitamin D levels and increased cardiovascular risk. Several mechanisms are involved in the development of cardiovascular diseases: systemic inflammation, endothelial dysfunction, arterial hypertension and insulin resistance. In the present paper, we have revised the current literature supporting a role for vitamin D in the development of these pathogenetic processes. Finally, we have evaluated the current evidence linking vitamin D to atherosclerosis and its natural consequence, cardiovascular diseases
