Higher Risk of Myocardial Infarction, Heart Failure, and Atrial Fibrillation Noted After Spinal Cord Injury
There are several factors which increase the risk of cardiovascular disease in survivors of spinal cord injury. They have a greater prevalence of obesity, dyslipidemia, metabolic syndrome and diabetes mellitus. Energy expenditure is lesser both due to lack of motor function and lack of opportunities to engage in physical activity. Autonomic dysfunction caused by spinal cord injury is associated with abnormalities in blood pressure, heart rate variability, arrhythmias and blunted cardiovascular response to exercise which can limit the capacity to perform physical activity [1]. A recent large study from Korea compared over 5...

Repeated Cycles of a Fasting-Mimicking Diet Reduce Measures of Biological Age
We report on the secondary outcome measures of the FMD-trial (NCT02158897) which are biomarkers associated with aging or age-related diseases, and metabolic syndrome, including visceral and hepatic fat, lymphoid/myeloid ratios, and blood markers, which were not investigated in the original report. We show that 3 FMD cycles in adult study participants are associated with reduced insulin resistance and other pre-diabetes markers, lower hepatic fat (as determined by magnetic resonance imaging), and increased lymphoid to myeloid ratio, an indicator of immune system age. Based on the Klemera-Doubal measure of biological a...

This study aimed to explore the metabolic mechanisms and potential biomarkers associated with declining HGS among older adults. We recruited 15 age- and environment-matched inpatients (age, 77-90 years) with low or normal HGS. Liquid chromatography-mass spectrometry (LC-MS) and 16S ribosomal DNA (rDNA) gene sequencing were performed to analyze the metabolome of serum and stool samples and the gut microbiome composition of stool samples. Spearman's correlation analysis was used to identify the potential serum and fecal metabolites associated with HGS. We assessed the levels of serum and fecal metabolites belonging to...

Why the Low Weight Group Exhibits Worse Outcomes in Some Epidemiological Studies
In this study, we first explored the association between WC, WHtR, and WWI change patterns and multimorbidity. WC and WHtR are considered to be important anthropometric indicators of abdominal obesity. Previous studies have suggested that WC and WHtR can reflect body fat percentage accurately and play an important role in predicting some chronic diseases, such as cardiovascular disease and metabolic syndrome. The pathway may explain that abdominal obesity significantly increased plasma triglycerides, low density lipoproteins, and very low density lipoproteins, which have been shown to increase the risk of adverse outcomes ...

Reviewing What is Known of the Mechanisms of Taurine Supplementation Relevant to Aging and Metabolism
Taurine is a semi-essential amino acid. Dietary taurine supplementation has been shown to modestly slow aging in mice, though as for all such interventions there is always the question of whether it will prove to be less useful in humans, and also whether these results in mice will be disproved by the much more rigorous Interventions Testing Program (ITP), once that group gets around to assessing taurine supplementation. Few of the numerous interventions thought to modestly slow aging in mice on the basis of earlier research actually held up once subjected to the ITP degree of experimental rigor. Speculatively, taur...

This study aimed to gather valuable insights from pharmaceutical experts and healthcare practitioners regarding the potential and challenges of translating senolytic drugs for treatment of vascular aging-related disorders. This study employed a qualitative approach by conducting in-depth interviews with healthcare practitioners and pharmaceutical experts. Participants were selected through purposeful sampling. Thematic analysis was used to identify themes from the interview transcripts. A total of six individuals were interviewed, with three being pharmaceutical experts and the remaining three healthcare practitioners. ...

Reviewing the Role of Insulin in Aging
The relationship between insulin metabolism and aging is one of the most studied areas of the field, with decades of researchers putting in time to deepen the understanding of the web of interactions surrounding insulin. Yet this has failed to lead to any practical outcome when it comes to slowing or reversing aging. Researchers now have an incrementally better idea as to why obesity, metabolic syndrome, and type 2 diabetes shorten life and worsen health, but that was well understood to be the case well prior to the advent of modern biotechnology. Experimental studies in animal models of aging such as nematodes, f...

A Study Reveals The Impact Of Childhood TV Habits On Adult Blood Pressure
Conclusion In sum, monitoring and managing screen time is not just about today’s habits but a long-term investment in a child’s future health, particularly their blood pressure levels. The data linking childhood TV viewing to adult health problems like high blood pressure underscores the urgency of this matter. However, understanding is just the first step. From here, we must translate this knowledge into action – through parental control, societal initiatives, healthier dietary habits, and increased physical activity. But we must also remember that screen time isn’t all bad – the conten...

In this study, we tested the hypothesis that periodontal disease (PD) as a source of infection alters inflammatory activation and Aβ phagocytosis by the microglial cells. Experimental PD was induced using ligatures in C57BL/6 mice for 1, 10, 20, and 30 days to assess the progression of PD. Animals without ligatures were used as controls. Ligature placement caused progressive periodontal disease and bone resorption that was already significant on day 1 post-ligation and continued to increase until day 30. The severity of periodontal disease increased the frequency of activated microglia in the brains on day 30 by 36...

Does true vegetarians carry less risk of developing CAD ?
Exclusive plant based diet protects heart and vasculature. Is it true ? “Yes it is.“ “No, It doesn’t.“ “Yes, a little bit” So, the answer is not stright-forward. Then as a scientist what should we do ? Do some good studies. Do we have it ? Ofcourse, we have far too many to confuse us. Which study showed vegetarians has less risk of CAD than non vegetarians? There have been several studies that have explored the association between vegetarian diets and the risk of coronary artery disease (CAD) compared to non-vegetarian diets. While not all studies show consist...

A Small Molecule to Reduce Mitochondrial Generation of Oxidative Stress
Researchers here report on an improved version of compounds known to reduce the generation of oxidizing molecules by mitochondria. Mitochondrial dysfunction can produce sustained oxidative stress that changes cell behavior for the worse, contributing to aspects of aging. That targeting antioxidants to the mitochondria or upregulating natural antioxidant molecules can produce some benefit to health suggests that the size of the contribution is meaningful. The details matter, however, and as cells use mild mitochondrial oxidative stress to trigger beneficial maintenance activities, with the metabolic response to exercise bei...
