Protein glycation: An old villain is shedding secrets.

Protein glycation: An old villain is shedding secrets. Comb Chem High Throughput Screen. 2019 Jul 03;: Authors: Lushington GH, Barnes AC Abstract The glycation of proteins is a non-physiological post-translational incorporation of carbohydrates onto the free amines or guanidines of proteins and some lipids. Although the existence of glycated proteins has been known for forty years, a full understanding of their pathogenic nature has been slow in accruing. In recent years, however, glycation has gained wide-spread acceptance as a contributing factor in numerous metabolic, autoimmune and neurological disorders, tying together several confounding aspects of disease etiology. From diabetes, arthritis and lupus, to multiple sclerosis, amyotrophic lateral sclerosis, Alzheimer's and Parkinson's diseases, an emerging glycation / inflammation paradigm now offers significant new insight into a physiologically important toxicological phenomenon. It exposes novel drug targets and treatment options, and may even lay foundations for long-awaited breakthroughs. This 'current frontier' article briefly profiles current knowledge regarding the underlying causes of glycation, the structural biology implications of such modifications and their pathological consequences. Although several emerging therapeutic strategies for addressing glycation pathologies are introduced, the primary purpose of this mini-review is to raise awareness of the challenges and opportunities inheren...

Patients interested in testing themselves at home for sleep apnea now have a few more options. Earlier this year Itamar Medical Ltd. introduced its third-generation WatchPAT home sleep apnea test (HSAT), the WatchPAT 300, and in June 2019, it debuted WatchPAT ONE, which the company calls the first and only disposable HSAT in the market. This month Blue Shield of California (BSC) and the Blue Cross Blue Shield Federal Employee Plan (BCBS FEP) included WatchPAT as a covered HSAT, Itamar reported in a news release. It added that changes in the U.S. Centers for Medicare &Medicaid Services (CMS) 2020 Fee Schedule are expect...

The human genome has been proposed to contribute to interpersonal variability in the way we respond to nutritional intake. However, personalized diets solely based on gene-nutrient interactions have not lived up to their expectations to date. Advances in microbiome research have indicated that a science-based generation of a personalized diet based on a combination of clinical and microbial features may constitute a promising new approach enabling accurate prediction of dietary responses. In addition, scientific advances in our understanding of defined dietary components and their effects on human physiology led to the inc...

It affects several organ systems, including the pulmonary and cardiac systems. Furthermore, it induces pulmonary and cardiac changes that can result in right and/or left heart failure.Areas covered: In this review, authors provide an overv...

In general, increased physical activity—primarily leisure time activity or moderate or vigorous physical activity—is associated with a 1–40% lower risk of hip and all fractures. The primary...

ConclusionsHOMA-IR can further stratify diabetes risk in AA adults beyond obesity, identifying non-obese high-risk and lower-risk obese individuals. However, diabetes risk should still be carefully monitored in obese populations despite insulin sensitivity.

In this study, we show that calorie restriction is protective against age-related increases in senescence and microglia activation and pro-inflammatory cytokine expression in an animal model of aging. Further, these protective effects mitigated age-related decline in neuroblast and neuronal production, and enhanced olfactory memory performance, a behavioral index of neurogenesis in the SVZ. Our results support the concept that calorie restriction might be an effective anti-aging intervention in the context of healthy brain aging. Greater Modest Activity in Late Life Correlates with Lower Incidence of Dementia ...
