Recent Longevity News for the week ending 9/15/21

Mediterranean Diet Tied to Less Severe Erectile Dysfunction - Medscape. 9/7/21 "The men with a higher Mediterranean diet score (> 29) had better erectile performance (SHIM scores > 14), as well as higher testosterone levels, higher coronary flow reserve, and less arterial stiffness than the other men"

Gut bacteria influence brain development - Science Daily, 9/3/21 - "The early development of the gut, the brain and the immune system are closely interrelated. Researchers refer to this as the gut-immune-brain axis. Bacteria in the gut cooperate with the immune system, which in turn monitors gut microbes and develops appropriate responses to them ... The microorganisms of the gut microbiome -- which is a vital collection of hundreds of species of bacteria, fungi, viruses and other microbes -- are in equilibrium in healthy people. However, especially in premature babies, whose immune system and microbiome have not been able to develop fully, shifts are quite likely to occur. These shifts may result in negative effects on the brain" - See probiotic supplements at Amazon.com and iHerb.

Sarcopenia Is Associated With Incident Alzheimer's Dementia, Mild Cognitive Impairment, and Cognitive Decline - Medscape, 9/3/21 - "More severe sarcopenia at baseline was associated with a higher risk of incident AD (hazard ratio [HR], 1.50 [95% confidence interval 1.20–1.86]; p < 0.001) and of MCI (1.21 [1.01–1.45]; 0.04) and a faster rate of cognitive decline" - Note:  Makes you wonder if supplements the help prevent sarcopenia such as leucine might also protect the noodle.

Antibiotics linked to increased risk of colon cancer - Science Daily, 9/1/21 - "women and men who took antibiotics for over six months ran a 17 per cent greater risk of developing cancer in the ascending colon, the first part of the colon to be reached by food after the small intestine, than those who were not prescribed any antibiotics. However, no increased risk was found for cancer in the descending colon. Nor was there an increased risk of rectal cancer in men taking antibiotics, while women taking antibiotics had a slightly reduced incidence of rectal cancer ... The increased risk of colon cancer was visible already five to ten years after taking antibiotics. Although the increase in risk was greatest for those taking most antibiotics, it was also possible to observe an admittedly small, but statistically significant, increase in the risk of cancer after a single course of antibiotics"

Moderna vaccine creates twice as many antibodies as Pfizer: research - Hill, 8/31/21 - "This research follows a preprint study released ahead of peer review earlier this month that suggested that the Moderna vaccine’s effectiveness dropped to 76 percent and the Pfizer shot’s effectiveness fell to 42 percent in July when the delta variant had taken hold in the U.S."

Immunomodulatory Effect of Withania somnifera (Ashwagandha) Extract—A Randomized, Double-Blind, Placebo Controlled Trial with an Open Label Extension on Healthy Participants - J Clin Med 2021 Aug 18 - "randomized placebo-controlled double-blinded study, subjects were allocated either 60 mg WS extract or placebo. It consists of a blinded 30-day period and an open-label extension study of another 30 days with crossover of only placebo to test. After the 30-day blinded study period, the WS test group reported significant increase (p < 0.05) in Ig's (IgA, IgM, IgG, IgG2, IgG3 and IgG4), Cytokines (IFN-γ, IL4), TBNK (CD45+, CD3+, CD4+, CD8+, CD19+, NK cells) whereas in the placebo group TBNK cells showed significant decrease (p < 0.05) and Ig's and cytokines showed no change (p > 0.05). In the extension period on day 60, the subjects on placebo who were crossed over to the WS test group showed significant increase (p < 0.05) in Ig's, cytokines and TBNK cells and the subjects who continued on the WS group showed a further significant improvement (p < 0.05) in Ig's, cytokines and TBNK cells. There were no adverse events reported in the study. WS extract significantly improved the immune profile of healthy subjects by modulating the innate and adaptive immune systems. Boosting the immune system of people at risk of infection and during widespread infections can be targeted with WS extract" - [Nutra USA] - See Ashwagandha at Amazon.com and iHerb.

A 6-month, double-blind, placebo-controlled, randomized trial to evaluate the effect of Eurycoma longifolia (Tongkat Ali) and concurrent training on erectile function and testosterone levels in androgen deficiency of aging males (ADAM) - Maturitas 2021 Mar - "Androgen deficiency of aging males (ADAM) largely manifests as sexual symptoms. Erectile dysfunction is one of the most common symptoms of ADAM ... 6-month, randomized, double-blind, placebo-controlled four-arm clinical. 45 men (47.38 ± 5.03 years) were randomized into 4 groups (G1: control + placebo; G2: control + Eurycoma longifolia; G3: concurrent training + placebo; G4: concurrent training + Eurycoma longifolia). 22 received a 200 mg supplement of Eurycoma longifolia and 23 underwent the intervention with concurrent training, 3 times a week for 60 min at progressive intensity ... Erectile function demonstrated improvements in both interventions; however, the most significant results were obtained by men allocated to concurrent training + Eurycoma longifolia" - [Nutra USA] - See Tongkat at Amazon.com.

Exercise associated or not to the intake of Eurycoma longifolia improves strength and cardiorespiratory fitness in men with androgen deficiency - Comp Ther Clin Prac, Feb 21 - "This study aims to analyze the effects of a concurrent training (CT) associated with Eurycoma longifolia (EL) supplementation on the muscle strength, cardiorespiratory fitness, and symptomatology score of men with the androgen deficiency of aging male (ADAM). Forty-five subjects (47.6 ± 5.2 years) were included in the study. The randomized, double-blinded, placebo controlled clinical trial lasted for 6 months. Participants were randomized into four groups, control (C; n = 12); EL (n = 11); CT (n = 11); and CT + EL (n = 11). Along this period, the isokinetic peak torque of the knee extensors increased in the CT (14%) and CT + EL (17%) groups (p = 0.040; p = 0.006, respectively), while the isokinetic peak torque of knee flexion increased in the CT + EL group only (p < 0.05). For all participants, testosterone levels were correlated with isokinetic peak torque of knee extension (r = 0.517, p = 0.001) and flexion (r = 0.362, p = 0.028). Subjects of the CT (27.3%) and CT + EL (36.1%) groups decreased the symptomatology of ADAM (p = 0.005). This study demonstrated the benefits of CT and EL consumption as a non-pharmacological treatment for ADAM" - [Nutra USA] - See Tongkat at Amazon.com.

Rutin, a flavonoid derivative of many plants, has numerous pharmacological effects ... In conclusion, rutin suppresses androgen biosynthesis in Leydig cells through multiple mechanisms, thereby having benefits for the treatment of androgen-sensitive prostate cancer" - See rutin at Amazon.com and rutin at iHerb.com.

Rutin: A Flavonoid as an Effective Sensitizer for Anticancer Therapy; Insights into Multifaceted Mechanisms and Applicability for Combination Therapy - Evid Based Complement Alternat Med 2021 Aug 23 - "Rutin is demonstrated to inhibit the proliferation of breast, colon, lung, and prostate cancers and other tumors. Furthermore, rutin alone or in combination with other therapeutic agents has been shown to regulate several signalling pathways involving the Ras/Raf and PI3K/Akt, MAPK, and TGF-β2/Smad2/3Akt/PTEN, etc., which are related to the processes of carcinogenesis and induction of apoptosis. The combination of rutin with other chemotherapy drugs may benefit on prevention of tumor cells by decreasing drug resistance and chemotherapy side effects. Moreover, rutin induces apoptosis synergistically with the therapeutic agent. More in vivo and clinical data are however needed to evaluate the true potential of rutin as an anticancer agent as an adjuvant. The present review highlights the effects of rutin which can be a promising candidate in combination with other antitumor drugs or alone for cancer treatment in vitro. Also, rutin can lead to decrease in drug resistance and chemotherapeutic side effects" - See rutin at Amazon.com and rutin at iHerb.com.

Vitamin B12, folate and homocysteine concentrations during pregnancy and early signs of atherosclerosis at school-age - Clin Nutr 2021 Aug 9 - "Circulating total B12, folate and homocysteine concentrations during fetal life seem to be associated with markers of subclinical atherosclerosis at school-age" - See B complex supplements at Amazon.com and iHerb.

Omega-3 fatty acid blood levels are inversely associated with cardiometabolic risk factors in HFpEF patients: the Aldo-DHF randomized controlled trial - Clin Res Cardiol 2021 Aug 28 - "Higher O3I was associated with a more favorable cardiometabolic risk profile and predictive of higher submaximal/maximal aerobic capacity and lower BMI/truncal adiposity in HFpEF patients. Omega-3 fatty acid blood levels are inversely associated with cardiometabolic risk factors in HFpEF patients. Higher O3I was associated with a more favorable cardiometabolic risk profile and aerobic capacity (left) but did not correlate with echocardiographic markers for left ventricular diastolic function or neurohumoral activation (right). An O3I-driven intervention trial might be warranted to answer the question whether O3-FA in therapeutic doses (with the target O3I 8-11%) impact on echocardiographic markers for left ventricular diastolic function and neurohumoral activation in patients with HFpEF" - See omega-3 supplements at Amazon.com and iHerb.

Luteolin combined with low-dose paclitaxel synergistically inhibits epithelial-mesenchymal transition and induces cell apoptosis on esophageal carcinoma in vitro and in vivo - Phytother Res 2021 Sep 7 - "Although paclitaxel is a promising frontline chemotherapy agent for various malignancies, the clinical applications have been restricted by side effects, drug resistance, and cancer metastasis. The combination of paclitaxel and other agents could be the promising strategies against malignant tumor, which enhances the antitumor effect through synergistic effects, reduces required drug concentrations, and also suppresses tumorigenesis in multiple ways. In this study, we found that luteolin, a natural flavonoid compound, combined with low-dose paclitaxel synergistically regulated the proliferation, migration, epithelial-mesenchymal transition (EMT), and apoptosis of esophageal cancer cells in vitro, as well as synergistically inhibited tumor growth without obvious toxicity in vivo. The molecular mechanism of inhibiting cell migration and EMT processes may be related to the inhibition of SIRT1, and the mechanism of apoptosis induction is associated with the reactive oxygen species (ROS)/c-Jun N-terminal kinase (JNK) pathway-mediated activation of mitochondrial apoptotic pathway" - See luteolin products at Amazon.com.

Anticancer effects of root and beet leaf extracts (Beta vulgaris L.) in cervical cancer cells (HeLa) - Phytother Res 2021 Sep 8 - "Cervical cancer is the fourth leading cause of cancer mortality in women worldwide.

Here, we demonstrate that beetroot and leaf extracts could be an efficient strategy against cervical cancer" - See beet root powder at Amazon.com.

The effects of lemon balm (Melissa officinalis L.) on depression and anxiety in clinical trials: A systematic review and meta-analysis - Phytother Res 2021 Aug 27 - "Based on meta-analysis results, lemon balm significantly improved mean anxiety and depression scores compared with the placebo (SMD: -0.98; 95% CI: -1.63 to -0.33; p = 0.003), (SMD: -0.47; 95% CI: -0.73 to -0.21; p = 0.0005) respectively, without serious side effects. Current evidence suggests that lemon balm may be effective in improving anxiety and depressive symptoms, particularly in the acute setting. Due to the high level of heterogeneity between studies, results should be interpreted with caution. The small number of clinical trials and differences between their methods were the limitations of the present study. Further high-quality studies are needed to firmly establish the clinical efficacy of the lemon balm" - See lemon balm at Amazon.com and iHerb.
