ISFAR Criticizes New Alcohol Guidance Issued by Canadian Centre on Substance Use and Addiction But Fails to Reveal Its Conflicts of Interest with Big Alcohol
Earlier this year, the Canadian Centre on Substance Use and Addiction released anew guidance on alcohol use. The guidance was notable for concluding that there is a dose-response relationship between the amount of alcohol one consumes and one ' s risk of disease or injury and therefore, greater amounts of alcohol consumption are associated with poorer health outcomes. In particular, the guidance concluded that drinking no alcohol is safer than drinking a low or moderate amount of alcohol.The International Scientific Forum on Alcohol Research (ISFAR) has just published a stingingcritique of the new guidance. The critique es...

Fight Aging! Newsletter, February 20th 2023
In this study, researchers stimulate the ghrelin receptor using a suitable small molecule for much of the lifespan of mice, and observe the results. The overall extension of life span is a quarter of that produced by calorie restriction, and so we might draw some conclusions from that as to the relative importance of hunger in the benefits resulting from the practice of calorie restriction or fasting. Interestingly, the short term weight gains observed in mice given this ghrelin receptor agonist in the past don't appear in this long term study, in which the controls are the heaver animals. This is possibly because the rese...

Automated Mass Spec Technique to Detect Antidepressants
Scientists at Brown University have designed an automated liquid chromatography tandem mass spectrometry (LC-MS/MS) system that allows clinicians to rapidly and easily process patient samples to determine levels of antidepressant drugs in the body. Getting the correct dose of antidepressant drugs into the bloodstream is important to ensure efficacy and avoid side-effects. However, current assays to measure the levels of such drugs in the blood are cumbersome, require large blood samples, and involve multiple time-consuming steps, limiting their use by clinicians. This new system requires very small sample volumes, and empl...

A New Record for the Longest Lived Laboratory Rat, Resulting from Plasma Dilution
Many more life span studies are carried out in mice rather than rats, so it is not too surprising to see people pushing the record for longest lived rat. The longest lived mice are those in which growth hormone receptor signaling is inhibited, while the longest lived rats are the result of life-long calorie restriction. The group noted here is pursuing a strategy of processing the blood plasma from young animals and then introducing the processed plasma into old animals. A treatment starting in mid-life produced a modest gain in median life span in rats, while the one still surviving rat from the small study group has surp...

Request for Startups in the Rejuvenation Biotechnology Space, 2023 Edition
It is time once again for my once-yearly set of unsolicited thoughts on biotech startups that I'd like to see join those already working hard on the basis for human rejuvenation. The industry is growing rapidly, but patchily. Partial reprogramming has received enormous attention, as has the development of senolytics. Meanwhile, other important goals in rejuvenation research languish, or presently have only one or two companies involved in clinical translation of promising academic projects. Many plausible paths forward go undeveloped; there are just as many opportunities to make a real difference in the world as there were...

This study investigated whether taller Polish adults live longer than their shorter counterparts. Data on declared height were available from 848,860 individuals who died in the years 2004-2008 in Poland. To allow for the cohort effect, the Z-values were generated. Separately for both sexes, Pearson's r coefficients of correlation were calculated. Subsequently, one way ANOVA was performed.
The correlation between adult height and longevity was negative and statistically significant in both men and women. After eliminating the effects of secular trends in height, the correlation was very weak (r = -0.0044 in men and ...

Reviewing the Development of Senotherapeutics
Today's open access paper is a very readable tour of the present state of research and development of therapies targeting senescent cells, whether to destroy them or alter their function in favorable ways. In both cases the primary goal is to reduce the senescence-associated secretory phenotype (SASP), the pro-growth, pro-inflammatory signaling that contributes to degenerative aging as the number of senescent cells rises over the course of later life. It is hoped that clearance of senescent cells will produce a sizable positive impact for late life health, reducing chronic inflammation, slowing the onset of near all age-re...

In conclusion, our study reveals that aging enhances atherosclerosis via increased inflammation of visceral fat. Our study suggests that future therapies targeting the visceral fat may reduce atherosclerosis diseaseburden in the expanding older population.

Got Calcium?
Someone’s hand moving to scroll through this blog post is possible because of a mineral that both gives bones their strength and allows muscles to move: calcium. As the most abundant mineral in our bodies, it’s essential for lots of important functions. It’s found in many foods, medicines, and dietary supplements.
Calcium keeps your bones strong, allows your muscles to move, and is important for many other bodily functions. The element is found in foods, medicines, and the world around us. Credit: Compound Interest CC BY-NC-ND 4.0. Click to enlarge.

A Discussion of the Biochemistry of Cardiac Fibrosis
Fibrosis is a malfunction of tissue maintenance, in which excessive amounts of extracellular matrix structure are created, forming scar-like features that disrupt normal tissue function. Fibrosis is a feature of aging and can rise to the level of life-threatening issue in organs such as the lung, liver, kidneys, and heart. This is particularly the case because there are no truly effective therapies to treat fibrosis; it is an inexorable condition that leads towards organ failure. Progress towards the reversal of fibrosis has been slow, unfortunately, despite the comparatively recent discovery that senescent cells appear to...

Microneedle Bandage for Hemostatic Control
Scientists at Penn State have developed a microneedle bandage that can rapidly stop bleeding. Uncontrolled bleeding following a traumatic injury is a major cause of death in the young, and developing new medical technologies that can rapidly stop bleeding would be highly beneficial. This bandage contains an array of biodegradable and biocompatible microneedles made using a gelatin methacryloyl biomaterial. The device also contains silicate nanoplatelets that give it its hemostatic properties, and the needle structure increases the surface area for blood contact and helps to bind the bandage to the injured tissue.

Flexible Sensors Detect Heavy Metals in Sweat
Researchers at the University of São Paulo in Brazil, along with collaborators in Germany and Sweden, have developed a flexible sensor that can detect heavy metals in sweat, an easily obtainable bodily fluid. Heavy metals, such as lead or cadmium, can cause serious toxicity if they accumulate in the body, but detecting the concentration of such metals in biological samples requires expensive laboratory equipment and skilled staff. To address this, these researchers have created a flexible sensor that is easy to use and which can detect metals in sweat samples before transmitting the results to a smartphone. The technology...
