How Alcohol Affects Blood Pressure: A Detailed Insight
Conclusion In this guide, we’ve explored the complex relationship between alcohol and blood pressure. We’ve seen that alcohol, whether consumed moderately, heavily, or in a binge pattern, can impact blood pressure. We also delved into the biological mechanisms at play, the role of various drinking patterns, and the sobering revelations of recent research. While the pleasure of a drink might be fleeting, its effects on our body, particularly on our blood pressure, can be long-lasting. The key takeaway? Moderation. Even a small reduction in alcohol intake can have significant health benefits, partic...

In this study, we investigated the effect of NXP032 on neurovascular stabilization through the changes of PECAM-1, PDGFR-β, ZO-1, laminin, and glial cells involved in maintaining the integrity of the blood-brain barrier (BBB) in aged mice. NXP032 was orally administered daily for 8 weeks. Compared to young mice and NXP032-treated mice, 20-month-old mice displayed cognitive impairments in Y-maze and passive avoidance tests. NXP032 treatment contributed to reducing the BBB damage by attenuating the fragmentation of microvessels and reducing PDGFR-β, ZO-1, and laminin expression, thereby mitigating astrocytes and microglia ...

The Gut Microbiome Differs in Characteristic Ways in Patients with Precancerous Colon Polyps
The gut microbiome changes with age, the relative abundance of microbial populations shifting in ways that appear connected to chronic inflammation and dysfunction of the intestinal epithelium and intestinal barrier function. Cancer of the colon is an important cause of human mortality, and there is some hope that finding ways to prevent or reverse gut microbiome aging, such as via fecal microbiota transplant from young individuals, will go some way to minimizing colon cancer incidence. Colorectal cancer is the second leading cause of cancer-related death in the U.S., and rates of colorectal cancer are rising amon...

Why poor diets are contributing to a surge in colorectal cancer cases among young people
An alarming trend has emerged in my medical practice in recent years: I’m seeing more and more young adults with colorectal cancer. When I began practicing as a family physician 21 years ago, I never saw patients in their 40s and 50s with the disease, much less ones in their 30s. Now, I diagnose two Read more… Why poor diets are contributing to a surge in colorectal cancer cases among young people originally appeared in KevinMD.com. (Source: Kevin, M.D. - Medical Weblog)

Conclusions Implanted Hair Follicle Cells Produce Remodeling of Scar Tissue Assessment of Somatic Mosaicism as a Biomarker of Aging The Gut Microbiome of Centenarians https://www.fightaging.org/archives/2023/01/the-gut-microbiome-of-centenarians/ The state of the gut microbiome is arguably as influential on health as exercise. Various microbial species present in the gut produce beneficial metabolites, such as butyrate, or harmful metabolites, such as isoamylamine, or can provoke chronic inflammation in a variety of ways. An individual can have a better or worse microbiome, assessing these and other...

In conclusion, the PAAIs examined (i.e. mTOR loss of function, Ghrhr loss of function, intermittent fasting-based version of dietary restriction) often influenced age-sensitive traits in a direct way and not by slowing age-dependent change. Previous studies often failed to include young animals subjected to PAAI to account for age-independent PAAI effects. However, any study not accounting for such age-independent intervention effects will be prone to overestimate the extent to which an intervention delays the effects of aging on the phenotypes studied. This can result in a considerable bias of our view on how modifiable a...

In this study researchers added new insight, showing that high-intensity aerobic exercise, which derives its energy from sugar, can reduce the risk of metastatic cancer by as much as 72%. If so far the general message to the public has been 'be active, be healthy', now researchers can explain how aerobic activity can maximize the prevention of the most aggressive and metastatic types of cancer. The study combined an animal model in which mice were trained under a strict exercise regimen, with data from healthy human volunteers examined before and after running. The human data, obtained from an epidemiological study ...

In this study, we show that TXNIP is vital for the cell fate choice when cells are challenged by various stress signals. Furthermore, prolonged IGF1 treatment leads to the establishment of a premature senescence phenotype characterized by a unique senescence network signature. Combined IGF1/TXNIP-induced premature senescence can be associated with a typical secretory inflammatory phenotype that is mediated by STAT3/IL-1A signaling. Finally, these mechanistic insights might help with the understanding of basic aspects of IGF1-related pathologies in the clinical setting. Investigating the Ability of Type 2 Diabetes...

They are analogous to macrophages in the rest of the body, but undertake additional duties relating to the function of neurons and in brain tissue. Microglia become overly active and inflamm...

In conclusion, this first examination of the effects of age and the ageing process on the small intestinal microbiome demonstrates that the duodenal microbiome changes with increasing age, with significant decreases in duodenal microbial diversity due to increased prevalence of phylum Proteobacteria, particularly coliforms and anaerobic taxa. Given the key roles of small intestinal microbes in nutrient absorption and host metabolism, these changes may be clinically relevant for human health during the ageing process.

Naked Mole Rats Exhibit Minimal Cardiac Aging
This study demonstrates that unlike mice that exhibit pronounced declines in body composition and cardiac function commencing shortly after sexual maturity, NMRs can maintain tissue homeostasis throughout their four-decade long maximum lifespan. Furthermore, NMRs do not show any signs of diastolic dysfunction or cardiac hypertrophy and maintain similar functional cardiac reserve capacity at advanced age to that exhibited when young adults, at the prime of life. Collectively, these data reveal that the naked mole-rat provides a proof-of-concept that age-related declines in body composition and cardiac function are not inevi...

In this study, we used accelerometer measurements (1) to examine the association of physical activity and mortality in a population-based sample of US adults and (2) to estimate the number of deaths prevented annually with modest increases in moderate-to-vigorous physical activity (MVPA) intensity. This analysis included 4,840 participants. Increasing MVPA by 10, 20, or 30 minutes per day was associated with a 6.9%, 13.0%, and 16.9% decrease in the number of deaths per year, respectively. We estimated that approximately 110,000 deaths per year could be prevented if US adults aged 40 to 85 years or older increased th...

In conclusion, mitophagy pathways play an important role in maintaining physiological homeostasis, are involved in the mechanisms of aging and neurodegenerative disorders, and represent promising targets for the development of potential therapeutic agents aimed at regulating mitochondria quality control in neurons and glial cells. A significant number of molecules that induce or inhibit mitophagy are currently under consideration, which may be useful for testing hypotheses or developing drugs for the treatment of neurodegenerative diseases. The validation of promising drugs in animal and cell models, including neurons and ...

In conclusion, this study examined how age and the process of aging are associated with changes in the microbiome of the small intestine, using validated sampling and processing techniques. The most significant differences are higher relative abundance of the phylum Proteobacteria and decreased relative abundance of Bacteroidetes in older subjects when compared to the youngest group. The higher relative abundance of Proteobacteria appeared to affect other duodenal microbial taxa, leading to decreased microbial diversity and increased relative abundance of coliforms and of anaerobic bacteria. The small intestine is vital to...
