Recent Longevity News for the week ending 2/1/23

CBD not shown to be safe enough for use in food or supplements, FDA says - Washington Post, 12623 - "I’m sure the FDA probably concluded that no matter which way they went, it would involve trying to fit a very big genie back into a very small bottle, and create a political firestorm" - Note: Who couldn't see that coming. React to the pot lobby then think about the consiquences later. For example, pot is a recipe for homelessness. It decreases motivation, can lower IQ by five points, increases susceptibility to schizophrenia, depression, and anxiety and it's a gate drug.

Τhe Endless Beauty of Metformin: Does It Also Protect from Skin Aging? A Narrative Review - Adv Ther 2023 Jan 30 - "Metformin has shown multiple effects beyond its widely known antidiabetic effect. Impressively, it has already been proposed as an anti-aging factor. However, the potentially protective role of metformin in skin aging, the most common manifestation of aging, is not well examined. Existing evidence based on experimental studies suggests a potential anti-aging effect on skin. Proposed molecular skin anti-aging mechanisms of metformin include mainly reduction of nuclear factor kappa B (NF-κB) (p65) activity. Moreover, metformin appears to inhibit ultraviolet B (UVB)-induced secretion of pro-inflammatory cytokines" - See metformin at ReliableRX.

Luteolin and Exercise Combination Therapy Ameliorates Amyloid-β1-42 Oligomers-Induced Cognitive Impairment in Alzheimer's Disease Mice by Mediating Neuroinflammation and Autophagy - J Alzheimers Dis 2023 Jan 25 - "Luteolin (100 mg/kg/d) combined with exercise could significantly improve the performance of AD model mice in novel object recognition test, and the improvement was greater than that of monotherapy. Further experiments showed that luteolin and exercise alone or in combination could reverse the increase of Aβ content, the activation of astrocytes and microglia, and the decrease of the level of autophagy in hippocampus and cortex in AD model induced by Aβ 1-42 oligomers. While the combination therapy involved more intact hippocampal and cortical areas, with greater degree of changes." - See luteolin products at Amazon.com.

Bifidobacterium longum supplementation improves age-related delays in fracture repair - Aging Cell 2023 Jan 27 - "Age-related delays in bone repair remains an important clinical issue that can prolong pain and suffering. It is now well established that inflammation increases with aging and that this exacerbated inflammatory response can influence skeletal regeneration. Recently, simple dietary supplementation with beneficial probiotic bacteria has been shown to influence fracture repair in young mice ... We found that B. longum supplementation accelerated bony callus formation which improved mechanical properties of the fractured limb. We attribute these pro-regenerative effects of B. longum to preservation of intestinal barrier, dampened systemic inflammation, and maintenance of the microbiota community structure. Moreover, B. longum attenuated many of the fracture-induced systemic pathologies. Our study provides evidence that targeting the gut microbiota using simple dietary approaches can improve fracture healing outcomes and minimize systemic pathologies in the context of aging." - See probiotic supplements at Amazon.com.

Blueberry treatment administered before and/or after lipopolysaccharide stimulation attenuates inflammation and oxidative stress in rat microglial cells - Nutr Neurosci 2023 Feb - "Microglia are key regulators of inflammation and oxidative stress (OS) in the CNS. Microglia activation can lead to chronic inflammation, OS, and neurodegeneration. Blueberries (BB) reduce inflammation and OS when administered to microglia before stressors such as lipopolysaccharide (LPS), but the therapeutic value of BBs administered after activation by stressors has not been examined ... Results suggest that BBs can target the downstream events of LPS-induced microglial activation and prevent stressor-induced neuroinflammation and OS. Furthermore, BBs may not need to be present prior to microglial activation for beneficial effects, suggesting that dietary interventions may be effective even after initiation of disease processes.Graphical Abstract. Cascade of inflammatory and OS-inducing events associated with self-propelling microglial activation by LPS and the effects of blueberry (0.5 mg/mL) administered before and/or after LPS on these processes (blue arrows). BB, blueberry; COX2, cyclooxygenase-2; IκB-ɑ, inhibitor kappa-B-ɑ; iNOS, inducible nitric oxide synthase; LPS, lipopolysaccharide; NF-κB, nuclear factor kappa-B; NO, nitric oxide; NOX2, NADPH oxidase; OS, oxidative stress; ROS, reactive oxygen species; TNFɑ, tumor necrosis factor-ɑ" - See blueberry extract at Amazon.com.

Effectiveness of a vitamin D regimen in deficient multiple myeloma patients and its effect on peripheral neuropathy - Support Care Cancer 2023 Jan 26 - "Peripheral neuropathy (PN) is common in multiple myeloma (MM) patients. More insight has been gained concerning the role of vitamin D in preventing PN. However, studies evaluating the effects of vitamin D3 supplementation on PN are lacking ... The use of substantially higher vitamin D3 doses than recommended in current guidelines resulted in a significant increase in vitamin D levels in MM patients. Furthermore, evaluation of PN showed a significant decrease in PN grading" - See vitamin D at Amazon.com.

Vitamin D3 and deconvoluting a rash - JCI Insight 2023 Jan 24 - "Adverse drug reactions are unpredictable immunologic events presenting frequent challenges to clinical management. Systemically administered cholecalciferol (vitamin D3) has immunomodulatory properties. In this randomized, double-blinded, placebo-controlled interventional trial of healthy human adults, we investigated the clinical and molecular immunomodulatory effects of a single high dose of oral vitamin D3 on an experimentally induced chemical rash ... High-dose systemic cholecalciferol may be an effective treatment for severe reactions to topical chemotherapy. Our findings have broad implications for cholecalciferol as an antiinflammatory intervention against the development of exaggerated immune responses" - See vitamin D at Amazon.com.

Neuroprotective effects of melatonin-mediated mitophagy through nucleotide-binding oligomerization domain and leucine-rich repeat-containing protein X1 in neonatal hypoxic-ischemic brain damage - FASEB J 2023 Feb;37 - "Hypoxia-ischemia (HI) is a major cause of brain damage in neonates. Mitochondrial dysfunction acts as a hub for a broad spectrum of signaling events, culminating in cell death triggered by HI. A neuroprotective role of melatonin (MT) has been proposed, and mitophagy regulation seems to be important for cell survival ... This study aimed to clarify whether NLRX1 participates in the regulation of mitophagy during MT treatment for hypoxic-ischemic brain damage (HIBD) ... In summary, MT modulates mitophagy induction through NLRX1 and plays a protective role in HIBD, providing insight into potential therapeutic targets for MT to exert neuroprotection" - See melatonin at Amazon.com.

Associations of different isomeric forms of serum lycopene with cardiovascular-disease and all-cause mortality - Int J Vitam Nutr Res 2023 Jan 24 - "Among 7452 participants (aged 20-85 years, 46.7% male), 298 died from CVDs among the total 1213 deaths during a median follow-up of 10.7 years. Serum lycopene is a protective factor for all-cause and CVD mortality. In multivariable-adjusted models, the hazard ratio (with 95% confidence intervals) associated with Q4 compared to Q1 of serum total-lycopene, trans-lycopene and cis-lycopene was 0.49 (0.38,0.63), 0.49 (0.39,0.63) and 0.55 (0.43,0.70) for all-cause mortality (Ptrend<0.05), and was 0.53 (0.32,0.96), 0.48 (0.32,0.72) and 0.63 (0.41,0.97) for CVD mortality (Ptrend<0.05). The subgroup analyses showed that different isomeric forms of lycopene showed varied associations with CVD and all-cause mortality based on age, drinking status, history of hypertension and diabetes. Conclusions: Serum lycopene concentration was significantly associated with the risk of CVD and all-cause mortality. Cis-lycopene had a U-shaped relationship with mortality, while trans-lycopene had an inverse relationship with it" - See lycopene at Amazon.com.

Treatment with the senolytics dasatinib/quercetin reduces SARS-CoV-2-related mortality in mice - Aging Cell 2023 Jan 26 - "The enormous societal impact of the ongoing COVID-19 pandemic has been particularly harsh for some social groups, such as the elderly. Recently, it has been suggested that senescent cells could play a central role in pathogenesis by exacerbating the pro-inflammatory immune response against SARS-CoV-2. Therefore, the selective clearance of senescent cells by senolytic drugs may be useful as a therapy to ameliorate the symptoms of COVID-19 in some cases. Using the established COVID-19 murine model K18-hACE2, we demonstrated that a combination of the senolytics dasatinib and quercetin (D/Q) significantly reduced SARS-CoV-2-related mortality, delayed its onset, and reduced the number of other clinical symptoms. The increase in senescent markers that we detected in the lungs in response to SARS-CoV-2 may be related to the post-COVID-19 sequelae described to date. These results place senescent cells as central targets for the treatment of COVID-19, and make D/Q a new and promising therapeutic tool" - See quercetin at Amazon.com.

Quercetin ameliorates hepatic fat accumulation in high-fat diet-induced obese mice via PPARs - Food Funct 2023 Jan 24 - "As a natural pigment in food, quercetin possesses multiple biological activities and plays a crucial role in regulating metabolic syndrome. Herein, we aim to explore the potential mechanism of quercetin to ameliorate hepatic fat accumulation. In vivo experiments showed that quercetin significantly relieved inflammation response by decreasing the serum TNF-α and IL-6 levels and also improved high-fat diet-induced hepatic steatosis without other organ injuries. Quercetin can effectively reduce lipid aggregation and down-regulate the protein expression of PCK1 in HepG2 cells induced by oleic acid and palmitic acid, indicating that inhibiting gluconeogenesis leads to hepatic fat accumulation reduction. Furthermore, molecular docking results suggested that quercetin can bind to both PPARα and PPARγ, with an even more potent binding affinity than indeglitazar, a pan-agonist of PPARs. In conclusion, quercetin may regulate gluconeogenesis to ameliorate hepatic fat accumulation via targeting PPARα/γ" - See quercetin at Amazon.com.
