Autologous Micro-Fragmented Adipose Tissue as Stem Cell-Based Natural Scaffold for Cartilage Defect Repair.

This study demonstrates the efficacy of MFAT on cartilage repair in an animal model for the first time, and the utility of MFAT as a ready-to-use therapeutic alternative to traditional stem cell therapy. PMID: 31565996 [PubMed - as supplied by publisher]

Authors: Fernández-Pernas P, Barrachina L, Marquina M, Rodellar C, Arufe MC, Costa C Abstract Rheumatic diseases such as osteoarthritis (OA) are a major social and economic burden because of the population aging and the lack of curative solutions. An effective cell therapy may be the best treatment option for OA and other cartilage diseases. However, the main cellular strategy used to repair articular cartilage, the transplantation of autologous chondrocytes, is limited to a small number of patients with traumatic lesions. The use of joint replacement after years of disease progression proves the great medic...

This study was the first to demonstrate a causal relationship between glial senescence and neurodegeneration. In this study, accumulations of senescent astrocytes and microglia were found in tau-associated neurodegenerative disease model mice. Elimination of these senescent cells via a genetic approach can reduce tau deposition and prevent the degeneration of cortical and hippocampal neurons. Most recently, it was shown that clearance of senescent oligodendrocyte progenitor cells in AD model mice with senolytic agents could lessen the Aβ plaque load, reduce neuroinflammation, and ameliorate cognitive deficits. ...

In conclusion, metabolomics is a promising approach for the assessment of biological age and appears complementary to established epigenetic clocks. Sedentary Behavior Raises the Risk of Cancer Mortality https://www.fightaging.org/archives/2020/06/sedentary-behavior-raises-the-risk-of-cancer-mortality/ Living a sedentary lifestyle is known to be harmful to long term health, raising the risk of age-related disease and mortality. Researchers here show that a sedentary life specifically increases cancer mortality, and does so independently of other factors. This is one of many, many reasons to maintain a re...

In this study, we used markers to monitor the formation of SGs in Caenorhabditis elegans. We found that, in addition to acute heat stress, SG formation could also be triggered by dietary changes, such as starvation and dietary restriction (DR). We found that HSF-1 is required for the SG formation in response to acute heat shock and starvation but not DR, whereas the AMPK-eEF2K signaling is required for starvation and DR-induced SG formation but not heat shock. Moreover, our data suggest that this AMPK-eEF2K pathway-mediated SG formation is required for lifespan extension by DR, but dispensable for the longevity by reduced ...

This study provides direct evidence for the contribution of gut microbiota to the cognitive decline during normal aging and suggests that restoring microbiota homeostasis in the elderly may improve cognitive function. On Nutraceutical Senolytics https://www.fightaging.org/archives/2020/05/on-nutraceutical-senolytics/ Nutraceuticals are compounds derived from foods, usually plants. In principle one can find useful therapies in the natural world, taking the approach of identifying interesting molecules and refining them to a greater potency than naturally occurs in order to produce a usefully large therape...

In this study, we found that older nematodes have higher ROS levels. Interestingly, after hydrogen treatment, the ROS levels were significantly decreased, and hydrogen could significantly extend the lifespans of the N2, sod-3 and sod-5 mutant strains, by approximately 22.7%, 9.5%, and 8.7%, respectively. In addition, aging is regulated by a variety of pathways, such as the insulin signaling pathway, the rapamycin target signaling pathway, and the caloric restriction pathway. However, our results showed that the lifespans of the daf-2 and daf-16 strains, in which these pathways are upregulated, were not affected afte...

The objective is to start treating chronic diseases from the root and not the symptoms of the disease. As we are starting to enroll patients in "senolytics-clinical trials," it will be imperative to assess if senolysis efficiently targets the primary cause of disease or if it works best in combination with other drugs. Additional basic science research is required to address the fundamental role of senescent cells, especially in the established contexts of disease.

In conclusion, our study demonstrated that Nrf2 deficiency promoted the increasing trend of autophagy during aging in skeletal muscle. Nrf2 deficiency and increasing age may cause excessive autophagy in skeletal muscle, which can be a potential mechanism for the development of sarcopenia.

This study is par for the course, looking at Japanese Olympic participants. Interestingly, it hints at the upper end of the dose-response curve for physical activity, in that a longer career as a professional athlete may be detrimental in comparison to lesser degrees of exercise and training. From this large, retrospective cohort study targeting 3546 Japanese Olympic athletes, we observed significant lower mortality among Olympians compared with the Japanese general population. The overall standardised mortality ratio (SMR) was 0.29. The results were consistent with previous studies conducted in other non-Asian co...
