A Population Study Correlates Air Pollution with Faster Cognitive Aging
https://www.fightaging.org/archives/2024/04/a-population-study-correlates-air-pollution-with-faster-cognitive-aging/
A number of large epidemiological studies provide evidence for long-term exposure to greater levels of air pollution to accelerate the onset and progression of age-related disease. A few of these manage to control for the tendency for wealthier people to avoid living in areas with higher particulate air pollution, ...

The Supreme Court must consider science, not pseudo-science, in public health rulings
Measles is on the rise in more than a dozen states, an alarming surge for a vaccine-preventable disease eliminated in the United States nearly 25 years ago. Meanwhile, young women exposed to relentless unscientific deception by social media algorithms are abandoning hormonal contraception in favor of significantly less effective methods that result in more unwanted

Mesenchymal Stem Cell Therapy Produces Thymus Regrowth in Old Non-Human Primates
Thymocytes generated in the bone marrow migrate to the thymus, near the heart, where they mature into T cells of the adaptive immune system. Unfortunately, the thymus atrophies with age. Most people have little active thymus tissue left by the time they are in their 50s. Absent a robust supply of new T cells, the adaptive immune system becomes ever more made up of malfunctioning, senescent, and other problematic cells, lacking the naive T cells needed to respond to new threats. Regeneration of the thymus is thus an important goal. There are some indications that the thymus is more plastic than thought, given that mild calo...

In this study, we tested a stem cell secretome product, which contains extracellular vesicles and growth factors, cytoskeletal remodeling factors, and immunomodulatory factors. We examined the effects of 4 weeks of 2×/week unilateral intramuscular secretome injections (quadriceps) in ambulatory aged male C57BL/6 mice (22-24 months) compared to saline-injected aged-matched controls.
Secretome delivery substantially increased whole-body lean mass and decreased fat mass, corresponding to higher myofiber cross-sectional area and smaller adipocyte size, respectively. Secretome-treated mice also had greater whole-bod...

An Urgent Call to Raise Awareness of Heart Disease in Women
By KELLY CARROLL
There is a dire need to raise awareness about heart disease in women. It is the number one killer of American women, and key data points reveal a lack of cognizance among doctors and women.
An assessment of primary care physicians published in 2019 revealed that only 22% felt extremely well prepared to evaluate cardiovascular disease risks in female patients. A 2019 survey of American women showed that just 44% recognized heart disease as the number one cause of death in women. Ten years earlier, in 2009, the same survey found that 65% of American women recognized heart disease as the leading cause o...

Costco Weight-Loss Program: Omission of Critical Data Puts Patients at (Financial) Risk
This week, the world learned that Costco Wholesale would start selling Novo Nordisk ' s newest, but vastly overpriced GLP-1 inhibitor medicine known generically as semaglutide (sold under the brand names Ozempic and Rybelsus for Type 2 diabetes, and under the brand name of Wegovy for weight-loss for those with obesity without Type 2 diabetes). We learned of the Costco GLP-1 initiative from a press release from Costco ' s strategic partner known as Sesamehttps://sesamecare.com/ which is the entity which will connect patients with its network of thousands of outpatient healthcare providers nationwide who are more than w...

This study supports the proposed model that aging-related loss of colonic crypt epithelial cell AMP gene expression can promote increased relative abundances of Gn inflammaging-associated bacteria and gene expression markers of colonic inflammaging. These data may support new targets for aging-related therapies based on intestinal genes and microbiomes.

Predicting the Order of Arrival of the First Rejuvenation Therapies
It has been going on eight years since I last speculated on the order of arrival of the first rejuvenation therapies. Tempus fugit, and time for an updated version! Eight years is a long enough span of time for the first of those rejuvenation therapies to now exist, albeit in a prototypical form, arguably proven in principle but not concretely. The world progresses but my biases remain much the same: the first rejuvenation therapies to work well enough to merit the name will be based on the SENS vision, that aging is at root caused by a few classes of accumulated cell and tissue damage, and biotechnologies that either repa...

Increased Dietary Leucine Activates mTOR Signaling in Macrophages, Accelerating Atherosclerosis
https://www.fightaging.org/archives/2024/02/increased-dietary-leucine-activates-mtor-signaling-in-macrophages-accelerating-atherosclerosis/
Leucine is an essential amino acid, only obtained from the diet rather than synthesized by our cells. Leucine supplementation has been proposed as a way to slow the loss of muscle mass with age, as leucine processing becomes dysregulated with aging in a way...

What is Known of the Contribution of Cellular Senescence to Osteoporosis
The vast majority of senescent cells are produced when somatic cells reach the Hayflick limit to cell division, their telomeres shortened to a point at which they either self-destruct or enter the senescent state. Damage due to mutation or cytotoxic compounds can also induce senescence, as can the regenerative processes following injury. Senescent cells cease replication, become larger, and change their behavior in many other ways. Senescent cells secrete a pro-growth, pro-inflammatory mix of signals, the senescence-associated secretory phenotype (SASP), that attracts the attention of immune cells capable of destroying sen...

Amie Fornah Sankoh Achieves a Scientific Dream
Credit: LinkedIn.
“I wanted to give up so many times. Although I tried to remain positive, I never thought I’d be able to finish my Ph.D. But I made it, and I’m extremely proud of myself,” says Amie Fornah Sankoh, Ph.D., a research scientist with Dow Chemical Company who received NIGMS support as a graduate student.
Human and Plant Communication
Dr. Sankoh has loved science and mathematics since she was just a child growing up in Sierra Leone. When she was 3 years old, Dr. Sankoh became deaf from a childhood disease. Math, unlike other subjects, is very visual, which played a part in her interest in it. “...

Digital Health, Menopause, And The $150 Billion Ignorance
The idea of this story came from personal experience. During the past year, I have spent countless hours and a bucketload of money trying to figure out what the heck is wrong with my health. I was feeling worse and worse, having various symptoms, totally inexplicable with my impeccable test results. During this journey, not a single doctor asked or suggested that my symptoms may come from entering perimenopause – the stage of life of women preceding menopause.
I am 47 years old, and as I have learned since then, extremely average in starting to have perimenopause symptoms at the age of 47. Also very average ...

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...
