Recent Longevity News for the week ending 3/16/22 What Is the Healthiest Salt for You? - Medscape, 2/28/22 - "Potassium chloride substitution in staple foods such as bread and bread products have serious and potentially fatal consequences for people who need to restrict dietary potassium. Improved food labeling is required for consumers to avoid excessive consumption" - Note: It's true that people on some medications can retain too much potassium but in most people they don't get enough potassium. I feel that nearly everyone should be using Lite salt and not even have regular salt in their household. There was a study about a couple of months ago that said that you potassium should be in the upper third of normal. 4.5 to 5.0. See Morton Salt Lite Salt, 11 oz, 2 pk at Amazon.com.
Eating protein from a greater variety of sources may lower risk of high blood pressure - Science Daily, 3/10/22 - "Participants were given a protein "variety score" based on the number of different sources of protein eaten out of 8 reported: whole grains, refined grains, processed red meat, unprocessed red meat, poultry, fish, egg and legumes. One point was given for each source of protein, with a maximum variety score of 8. The researchers then evaluated the association for new onset hypertension in relation to the protein variety score ... Compared to participants with the lowest variety score for protein intake (less than 2), those with the highest variety score (4 or higher) had a 66% lower risk of developing high blood pressure." High Fructose Intake May Trigger Fatty Liver Disease - Medscape, 3/7/22 - "A high intake of fructose may increase the risk of nonalcoholic fatty liver disease, in which too much fat is stored in liver cells ... Researchers found that consuming a high-fructose diet for long periods can lead to a deterioration of the layer of cells that creates the intestinal barrier that prevents bacteria and toxins from leaking into the bloodstream and affecting the liver ... Fatty liver disease can lead to liver inflammation and liver damage, resulting in nonalcoholic steatohepatitis, a more aggressive disease that in turn can progress to scarring of the liver (cirrhosis), liver cancer, and liver failure ... Severe fatty liver disease and liver tumors from the gut barrier deterioration created by excessive fructose intake can be prevented with medications" Dietary Fiber Tied to Lower Dementia Risk - Medscape, 3/7/22 - "Investigators administered a dietary survey to 3700 healthy adults at midlife and then followed them for up to 20 years. They found that participants who consumed the most fiber had approximately a 25% lower risk of developing dementia in later life ... This study showed that people with a high intake of dietary fiber, especially soluble fiber, have a lower risk of dementia ... Brain-gut interaction has recently received attention for its potential involvement in the development of dementia ... A diet high in soluble fiber attenuates neuroinflammation in mouse models. Other animal studies have suggested that insoluble fiber might also have a beneficial effect on the microbiome"
More alcohol, less brain: Association begins with an average of just one drink a day - Science Daily, 3/4/22 - "Researchers analyzed data from more than 36,000 adults that found a link between drinking and reduced brain volume that begins at an average consumption level of less than one alcohol unit a day -- the equivalent of about half a beer -- and rises with each additional drink" In my last three newsletters I’ve been pointing out how people prefer BS over the truth and that that’s where the money is. This CNN 3/3/22 segment says the exact same thing. Look at Fox News, Trump, the 64-year-old U.K. nurse with a Ph.D., Dr. John Campbell, who looks like he’s 85 who puts out misinterpretations and lies praising ivermectin and downplaying vaccines and gets millions of views on YouTube every day, etc. CNN claims people just want to believe in miracles. They’re being too kind, they’re gullible.
More on how BS sells. 700,000 views in 22 hours. Same for people like Tucker Carlson, Sean Hannity, Trump, Fox News in general, etc. Dr. Campbell even comes across as deranged yet just like Trump, people love him. He has to be the biggest snake oil salesman in history. I just don't get it but that's were the big money is. Garry IQ of 190 Kasparov might have the answer. In layman terms, he thinks it's deterioration of the mind from poor life style such as drinking, smoking, poor diet, etc. That said, would I do it over again and become rich selling lies? Nope.
Athletes Face Twice the Odds for A-Fib - WebMD, 7/13/21 - "Overall, athletes had about a 2.5 times higher risk of a-fib than non-athletes. But when the researchers focused on participants without heart disease risk factors (such as type 2 diabetes and high blood pressure), they found that athletes had nearly four times the risk of a-fib compared to non-athletes" Note: I’ve probably out-jogged and out-swam the average athlete by a factor of 4 so my odds of afib should be about 10 times higher than the average non-athlete. I've got premature ventricular contractions (PVCs) which is an electrical problem in the lower chamber of the heart vs. afib which is the upper chamber. Here's my store along with two stories of old athletes like me with the same problem:
Abstracts from this week: Sodium-glucose co-transporter 2 inhibitor therapy: use in chronic kidney disease and adjunctive sodium restriction - Intern Med J 2022 Mar 7 - "Hence, blood pressure (BP) reduction is a vital component of CKD management. Sodium-glucose co-transporter 2 (SGLT2) inhibitors are a relatively novel class of medications developed to treat T2DM by inducing glycosuria and hence, lowering glycaemia. Additionally, SGLT2 inhibitors are antihypertensive, renoprotective and cardioprotective, even in individuals without T2DM, making them promising therapeutic agents for CKD, regardless of aetiology" - See empagliflozin at ihouseepharmacy. The effect of an mRNA vaccine against COVID-19 on endothelial function and arterial stiffness - Hypertens Res 2022 Mar 10 - "Our study shows that the mRNA vaccine causes a prominent increase in inflammatory markers, especially after the 2nd dose, and a transient deterioration of endothelial function at 24 h that returns to baseline at 48 h" Long-Term Cannabis Use and Cognitive Reserves and Hippocampal Volume in Midlife - Am J Psychiatry 2022 Mar 8 - "Long-term cannabis users showed IQ decline from childhood to midlife (mean=-5.5 IQ points), poorer learning and processing speed relative to their childhood IQ, and informant-reported memory and attention problems ...

Severe drug interactions have also been reported in both animals and humans when combined with other medications" - See Ginkgo biloba at Amazon.com. CD38 inhibitor 78c increases mice lifespan and healthspan in a model of chronological aging - Aging Cell 2022 Mar 8 - "Nicotinamide adenine dinucleotide (NAD) levels decline during aging, contributing to physical and metabolic dysfunction. The NADase CD38 plays a key role in age-related NAD decline. Whether the inhibition of CD38 increases lifespan is not known. Here, we show that the CD38 inhibitor 78c increases lifespan and healthspan of naturally aged mice. In addition to a 10% increase in median survival, 78c improved exercise performance, endurance, and metabolic function in mice. The effects of 78c were different between sexes. Our study is the first to investigate the effect of CD38 inhibition in naturally aged animals" - See nicotinamide adenine dinucleotide at Amazon.com.

Diosmin, a citrus fruit-derived phlebotonic bioflavonoid protects rats from chronic kidney disease-induced loss of bone mass and strength without deteriorating the renal function - Food Funct 2022 Feb 21 - "Kidney Disease Improving Global Outcomes (KDIGO) 2017 Clinical Practice Guideline has recommended treatment decisions for patients with chronic kidney disease (CKD) with osteoporosis and/or high risk of fracture. Bisphosphonates, the first-line anti-osteoporosis drugs have the concern of worsening kidney functions. Moreover, despite impaired bone formation in CKD patients, teriparatide, the formation-stimulating drug is not recommended. Thus, there is an urgent need for safe and effective treatment of osteoporosis in CKD patients ... Fibroblast growth factor-23 and parathyroid hormone were increased in CKD and diosmin suppressed both. CKD reduced bone mass and deteriorated the microarchitecture of trabecular bones, and diosmin maintained both to control levels. Bone formation and strength were impaired in the CKD and diosmin maintained these levels to control levels. Nanoindentation of bone showed that diosmin significantly increased tissue hardness over the control. Diosmetin, the metabolic surrogate of diosmin had comparable pharmacokinetic profiles between the control and CKD groups. Furthermore, diosmetin (50 mg kg-1) protected against CKD-induced bone loss. These data suggest that diosmin and its metabolic surrogate, diosmetin protect against CKD-induced osteopenia. Since diosmin has no renal adverse effect and protected bone mass and strength in CKD rats, we propose assessing its anti-osteoporosis effect in CKD patients" - See diosmin at Amazon.com. Impact of high-intensity interval training with or without l-citrulline on physical performance, skeletal muscle, and adipose tissue in obese older adults - J Cachexia Sarcopenia Muscle 2022 Mar 7 - "Aging is associated with a progressive decline in skeletal muscle mass and strength as well as an increase in adiposity. These changes may have devastating impact on the quality of life of older adults ... High-intensity interval training is effective in improving functional capacities, lean mass, muscle power, and waist circumference in obese older adults. HIIT also increases markers of mitochondrial biogenesis, mitochondrial fusion, and mitophagy. Importantly, adding CIT to HIIT results in a greater increase in muscle strength and a significant decrease in fat mass. The present study therefore positions HIIT combined with CIT as an effective intervention to improve the health status of obese older adults" - See l-citrulline at Amazon.com. Ginsenoside compound K inhibits obesity-induced insulin resistance by regulation of macrophage recruitment and polarization via activating PPARγ - Food Funct 2022 Mar 8 - "The results showed that CK could dose-dependently reduce macrophage M1-type inflammatory factor expression in serum and adipose tissue, improve insulin resistance and glucose tolerance effectively, upregulate PPARγ expression and block TLR4/TRAF6/TAK1/NF-κB activation in obese mice. In addition, CK promoted the expression of IRS1/PI3K/AKT. Furthermore, our study showed that ginsenoside CK could improve insulin resistance by reducing inflammation through the PPARγ/NF-κB signaling pathway, which implies that ginsenoside CK may be an effective agent against obesity or early diabetes" - See ginseng at Amazon.com. Exploring the Mechanism of Astragalus propinquus Schischkin and Panax Notoginseng (A&P) Compounds in the Treatment of Renal Fibrosis and Chronic Kidney Disease Based on Integrated Network Analysis - Evid Based Complement Alternat Med 2022 Feb 27 - "Astragalus propinquus Schischkin and Panax notoginseng (A&P) has been widely used in clinical practice to treat chronic kidney disease (CKD) for many years and achieved a remarkable improvement of these outcomes ... What's more, the effect of A&P and potential genes was furthermore verified by using unilateral ureteral ligation (UUO) in rodent model. The results showed that the expression of HSF1 and RELA both at transcript and protein level was significantly upregulated in UUO model, but the expression was markedly reversed after A&P intervention. To further guide the interpretation of active ingredients from A&P on the effect of HSF1 and RELA, we performed a molecular docking assay and the results showed that active ingredients such as coptisine docked well into HSF1 and RELA. In total, these results suggest that A&P may improve RF in CKD by regulating HSF1 and RELA, which provides a basis for further understanding the mechanism of A&P in the treatment of RF and CKD" - See astragalus at Amazon.com and Panax ginseng at Amazon.com.

Effects of alpha lipoic acid on metabolic syndrome: A comprehensive review - Phytother Res 2022 Mar 2 - "Metabolic syndrome (MetS) is a multifactorial disease with medical conditions such as hypertension, diabetes, obesity, dyslipidemia, and insulin resistance. Alpha-lipoic acid (α-LA) possesses various pharmacological effects, including antidiabetic, antiobesity, hypotensive, and hypolipidemia actions. It exhibits reactive oxygen species scavenger properties against oxidation and age-related inflammation and refines MetS components. Also, α-LA activates the 5' adenosine monophosphate-activated protein kinase and inhibits the NFκb. It can decrease cholesterol biosynthesis, fatty acid β-oxidation, and vascular stiffness. α-LA decreases lipogenesis, cholesterol biosynthesis, low-density lipoprotein and very low-density lipoprotein levels, and atherosclerosis. Moreover, α-LA increases insulin secretion, glucose transport, and insulin sensitivity. These changes occur via PI3K/Akt activation. On the other hand, α-LA treats central obesity by increasing adiponectin levels and mitochondrial biogenesis and can reduce food intake mainly by SIRT1 stimulation" - See alpha lipoic acid at Amazon.com. Molecular Targets of Curcumin and Its Therapeutic Potential for Ovarian Cancer - Nutr Cancer 2022 Mar 10 - "Ovarian cancer is the fifth most common gynecological cancer in women globally. Conventional chemotherapy is the first therapeutic approach in the treatment of ovarian cancer, but its success is limited by severe side effects, transient response, and the high prevalence of relapse. Curcumin is a natural product found in the rhizome extract of Curcuma longa and has been extensively used over the last decades for its unique biological and medicinal properties, which include: having antioxidant, analgesic, anti-inflammation, and anti-tumor activities. Curcumin exerts its anticancer properties against ovarian cancer via multiple mechanisms: interfering with cellular interactions necessary for metastasis and recurrence of OC cells, increasing pro-apoptotic proteins as well as inducing or suppressing generation of different molecules such as cytokines, transcription factors, enzymes, protein kinases, and growth factors. Moreover, curcumin down-regulates various signaling pathways such as PI3K/Akt, Wnt/β-catenin, JAK/STAT3, and MEK/ERK1/2 axes, which at least in part have a role in inhibiting further tumor proliferation, growth, and angiogenesis" - See curcumin at Amazon.com. Curcumin regulates the homeostasis of Th17/Treg and improves the composition of gut microbiota in type 2 diabetic mice with colitis - Phytother Res 2022 Mar 2 - "Diabetes mellitus (DM) is one of the most common complications in patients with ulcerative colitis (UC). Curcumin has a wide range of bioactive and pharmacological properties and is commonly used as an adjunct to the treatment of UC and DM ... In this study, curcumin (100 mg/kg/day) significantly improved the symptoms of diabetes complicated by UC, with a lower insulin level, heavier weight, longer and lighter colons, fewer mucosal ulcers and less inflammatory cell infiltration. Moreover, compared to untreated DB mice with colitis, curcumin-treated mice showed weaker Th17 responses and stronger Treg responses. In addition, curcumin regulated the diversity and relative abundance of intestinal microbiota in mice with UC complicated by DM at the phylum, class, order, family and genus levels. Collectively, curcumin effectively alleviated colitis in mice with type 2 diabetes mellitus by restoring the homeostasis of Th17/Treg and improving the composition of the intestinal microbiota" - See curcumin at Amazon.com.

Resveratrol Blunts Mitochondrial Loss in Slow and Mixed Skeletal Muscle Phenotypes of Non-Human Primates following a Long-Term High Fat/Sugar Diet - J Diet Suppl 2022 Mar 1 - "Mitochondrial biogenesis and destruction in skeletal muscle are coordinated by distinct signaling pathways that are influenced by internal and exogenous variables including, but not limited to, muscle phenotype, physical activity, dietary composition, or drug administration. Previously we found that long-term resveratrol administration (up to 480 mg/day) ameliorates the slow-to-fast phenotypic shift in soleus muscles and promotes the expression in slow myosin heavy chain in the mixed plantaris muscle of non-human primates consuming a high fat/sugar (HFS) diet ... Taken together, resveratrol appears to blunt mitochondrial losses with a high fat/sugar diet by tempering mito/autophagy rather than promoting mitochondrial biogenesis, suggesting that the quantity of daily resveratrol supplement ingested and/or its long-term consumption are important considerations" - See resveratrol products at Amazon.com. Phycocyanin ameliorates mouse colitis via phycocyanobilin-dependent antioxidant and anti-inflammatory protection of the intestinal epithelial barrier - Food Funct 2022 Mar 4 - "Phycocyanin, phycocyanobilin and a positive drug mesalazine were intragastrically administered to C57BL/6 mice daily for 7 days during and after 4-day DSS exposure. Clinical signs and colon histopathology revealed that phycocyanin and phycocyanobilin had an equivalent anti-colitis efficacy that was even superior to mesalazine. Based on biochemical analysis of colonic tight junction proteins, mucus compositions and goblet cells, and colonic and peripheral proinflammatory cytokines, phycocyanin and phycocyanobilin displayed equivalent intestinal epithelial barrier-protecting and anti-inflammatory potential that was evidently superior to that of mesalazine ... Overall, our results demonstrate the phycocyanobilin-dependent anti-colitis role of phycocyanin via antioxidant and anti-inflammatory mechanisms" - See phycocyanin at Amazon.com.
Enhanced co-culture and enrichment of human natural killer cells for the selective clearance of senescent cells - Aging (Albany NY) 2022 Mar 4 - "In the context of aging and age-associated diseases, Natural Killer (NK) cells have been revealed as a key cell type responsible for the immune clearance of senescent cells. Subsequently, NK cell-based therapies have emerged as promising alternatives to drug-based therapeutic interventions for the prevention and treatment of age-related disease and debility. Given the promise of NK cell-mediated immunotherapies as a safe and effective treatment strategy, we outline an improved method by which primary NK cells can be efficiently enriched from human peripheral blood across multiple donors (ages 20-42 years old), with a practical protocol that reliably enhances both CD56dim and CD56bright NK cells by 15-fold and 3-fold, respectively. Importantly, we show that our co-culture protocol can be used as an easily adaptable tool to assess highly efficient and selective killing of senescent cells by primary NK cells enriched via our method using longer co-culture durations and a low target to effector ratio, which may be more physiological than has been achieved in previous literature" Restorative effects of probiotics on memory impairment in sleep-deprived mice - Nutr Neurosci 2022 Mar 3 - "These findings demonstrate that Lpc-37 and the multi-strain may play a role in alleviating memory impairments and improve cognitive function in partially sleep-deprived mice" - See probiotic supplements at Amazon.com.
