This study reveals a potential treatment for human mitochondrial diseases. « Back to Top 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, ...

Ballooning an obstructed prosthetic Aortic valve : Can be a real tense procedure!
A 76-year-old woman with a history of double valve replacement (Aortic and mitral valves) for rheumatic heart disease, presented with acute dyspnea after a switch from Warfarin to LMWH before a planned bone marrow biopsy. The investigations revealed a stuck aortic prosthetic valve ,that showed a prohibitive gradient of more than 50 mmhg. Since, she refused further surgery, a rare and risky effort was made to balloon dilate the prosthetic valve leaflet, though it is not a standard approved modality. It was decided to dilate the supero-lateral orifice and the central orifices by simultaneous kissing balloon. The results w...

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...

In conclusion, HSV (but not CMV) infection may be indicative of doubled dementia risk. « Back to Top 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...

This study explored the association between different cooking fuel types and the risk of cancer and all-cause mortality among seniors constructing Cox regression models. Data were obtained by linking waves of 6, 7, and 8 of the Chinese Longitudinal Healthy Longevity Survey, which included a total of 7,269 participants who were 65 years old and over. Cooking fuels were categorized as either biomass, fossil, or clean fuels. And the effects of switching cooking fuels on death risk were also investigated using Cox regression models. The results indicate that, compared with the users of clean fuels, individuals using bio...

High-Throughput Testing of Hundreds of Anti-Cancer Drug Combinations
Researchers at ETH Zurich in Switzerland have developed a high-throughput screening method for anti-cancer drugs that they have called “pharmascopy”. To date, the researchers have tested the system with multiple myeloma samples, a cancer that has a poor prognosis and is difficult to treat because of drug resistance. In such cancers, finding the right drug or drug combination for a given patent is critical. The approach involves seeding the cancer cells into 384-well plates, and then placing different drugs or drug combinations into each well. After a 24 hour period of incubation, the cells can be labelled with ...

In conclusion, frailty progression accelerates in males with one LTCs and females with two LTCs or more. Health providers should be aware of planning a suitable intervention once the elderly have two or more health conditions. Plasma Transfer Lowers Epigenetic Age and Mortality in Rats https://www.fightaging.org/archives/2023/04/plasma-transfer-lowers-epigenetic-age-and-mortality-in-rats/ Plasma transfer from young to old individuals has produced mixed results in animals and little to no benefit in humans where assessed rigorously. These studies were driven by the hypothesis that young plasma contains m...

In this study, we develop a rFOXN1 fusion protein that contains the N-terminal of CCR9, FOXN1, and TAT. We show here that, when injected intravenously (i.v.) into aged mice, the rFOXN1 fusion protein can migrate into the thymus and enhance T cell generation in the thymus, resulting in increased number of peripheral T cells. Our results suggest that the rFOXN1 fusion protein has the potential to be used in preventing and treating T cell immunodeficiency in the older adult.

In conclusion, this study confirms that innate immune training can be induced in aging healthy individuals as well as critically ill sepsis patients. We found that innate immune training can be induced regardless of age and there was no substantive difference in the immune trained phenotype as a function of age. We employed β-glucan as our immune training stimulus. The ability of glucan to induce the trained phenotype suggests that it may be possible to pharmacologically induce the immune trained phenotype in aging human immunocytes.

In conclusion, we summarized here evidence for a novel therapeutic approach to exploit the incredible ability of mitochondria to engage multifaceted neuroprotective stress response triggered by partial complex I inhibition. This approach promises relief for multiple human conditions, and to promote healthy aging to delay the onset of neurogenerative diseases, AD in particular, where age is the greatest risk factor. There is a mounting body of evidence generated in model organisms and humans in support of the safety of chronic application of complex I inhibitors. However, a better understanding of the molecular mechanisms i...

Targeting Cellular Senescence as a Basis for Treating Osteoporosis
Senescent cells accumulate with age, causing tissue dysfunction throughout the body via their inflammatory secretions. One of those dysfunctions is the age-related imbalance in bone remodeling, favoring the osteoclasts that break down bone tissue at the expense of the osteoblasts that rebuild it. The result is osteoporosis, the characteristic loss of bone mass and resilience that takes place with age. It has been clear for some years now that clearing senescent cells in aged individuals is a potential basis for the treatment of osteoporosis, producing a reversal of the condition in animal models treated in this way. This o...

In this study, they found these drugs can kill senescent cells from cultures of human fat tissue. The tissue was donated by individuals with obesity who were known to have metabolic troubles. Without treatment, the human fat tissues induced metabolic problems in immune-deficient mice. After treatment with dasatinib and quercetin, the harmful effects of the fat tissue were almost eliminated. Targeting p21Cip1 highly expressing cells in adipose tissue alleviates insulin resistance in obesity Insulin resistance is a pathological state often associated with obesity, representing a major risk factor for type 2...
