This study examined whether the local injection of the supernatant of activated PRP (saPRP) into the salivary gland (SG) could help prevent aging-induced SG dysfunction and explored the mechanisms responsible for the protective effects on the SG hypofunction.
Human salivary gland epithelial cells (hSGEC) were treated with saPRP or PRP after senescence through irradiation. The significant proliferation of hSGEC was observed in saPRP treated group compared to irradiation only group and irradiation + PRP group. Cellular senescence, apoptosis, and inflammation were significantly reduced in the saPRP group.

In this study, researchers show that mice lacking a functional ATF4 gene show little to no loss of grip strength and treadmill performance into late life; it is quite an impressive effect size. Assessments of muscle biochemistry do show age-related declines, but to a lesser degree than the controls. How ATF4 knockout functions to produce this outcome is an interesting question. The researchers point out a range of possible downstream and upstream targets that have been implicated in the regulation of muscle growth, but it will clearly require further work to identify the important mechanisms involved.

Reviewing the Aging of the Gut Microbiome
Researchers here take a high level tour of what is known of age-related changes in the gut microbiome and how they influence health. Accumulating evidence shows a loss of beneficial populations that generate useful metabolites such as butyrate, accompanied by an increase in harmful populations that can provoke chronic inflammation. This is a likely a meaningful contribution to the onset and development age-related conditions, making it a priority to develop ways to reset the balance of populations in the gut microbiome. The best of the available approaches, given the evidence to date, is fecal microbiota transplantation fr...

Point-Of-Care Biosensor to Detect Oral Cancer
Researchers at the University of Florida have created a point-of-care biosensor that can rapidly detect a biomarker for oral cancer. The device uses test strips, such as those used in blood glucose tests, to spot cell proliferation regulating inhibitor of protein phosphatase 2A (CIP2A), a protein biomarker that can reveal the presence of oral cancer. The device requires a liquid sample that is introduced to the end of the test strip, where it runs into channels that contain antibody-covered electrodes. The antibodies are specific for CIP2A, and antibody binding changes the electrical signal the electrodes produce, providin...

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.

In conclusion, in our prospective community-based study, aging-related biomarkers were associated with measures of subclinical atherosclerosis cross-sectionally and with all-cause mortality prospectively, supporting the concept that these biomarkers may reflect the aging process in community-dwelling adults.

The objective of this study is to quantify the overall and cancer type-specific risks of subsequent primary cancers (SPCs) among adult-onset cancer survivors by first primary cancer (FPC) types and sex. Among 1,537,101 survivors (mean age, 60.4 years; 48.8% women), 156,442 SPC cases and 88,818 SPC deaths occurred during 11,197,890 person-years of follow-up (mean, 7.3 years). Among men, the overall risk of developing any SPCs was statistically significantly higher for 18 of the 30 FPC types, and risk of dying from any SPCs was statistically significantly higher for 27 of 30 FPC types as compared with risks in the general po...

Cancer Survivors Exhibit Greater Risk of New Cancers and Higher Mortality Due to those Cancers

In conclusion, we found that regardless of the presence of multimorbidity, engaging in a healthier lifestyle was associated with up to 6.3 years longer life for men and 7.6 years for women; however, not all lifestyle risk factors equally correlated with life expectancy, with smoking being significantly worse than others.

In this study, we applied a well studied prediction model developed on data from five CpG sites, to increase the practicability of these tests.
We have determined the biological age of the heart, specifically of the right atrium (RA) and left atrium (LA), and of peripheral blood leucocytes, by measuring the mitotic telomere length (TL) and the non-mitotic epigenetic age (DNAmAge). We found that DNAmAge, of both atrial tissues (RA and LA), was younger in respect to the chronological age (-12 years). Furthermore, no significant difference existed between RA and LA, suggesting that, although anatomically diverse and ex...

In this study, by adenovirus-mediated delivery and inducible transgenic mouse models, we demonstrate the proliferation of both HCs and SCs by combined Notch1 and Myc activation in in vitro and in vivo inner ear adult mouse models. These proliferating mature SCs and HCs maintain their respective identities. Moreover, when presented with HC induction signals, reprogrammed adult SCs transdifferentiate into HC-like cells both in vitro and in vivo. Finally, our data suggest that regenerated HC-like cells likely possess functional transduction channels and are able to form connections with adult auditory neurons.

Precision Medicine and Public Health (from Precision Medicine and the Reinvention of Human Disease)
Excerpted fromPrecision Medicine and the Reinvention of Human DiseaseDespite having the most advanced healthcare technology on the planet, life expectancy in the United States is not particularly high. Citizens from most of the European countries and the highly industrialized Asian countries enjoy longer life expectancies than the United States. According to the World Health Organization, the United States ranks 31st among nations, trailing behind Greece, Chile, and Costa Rica, and barely edging out Cuba [42]. Similar rankings are reported by the US Central Intelligence Agency [43]. These findings lead us to infer that acc...

Offensive overselling of the #microbiome in breast cancer from the Cleveland Clinic
This study does not provide ANY proof of principle of this sort. You have not shown there are any pro-cancer bacteria. This is ridiculous and offensive. No wonder the news stories imply that this study is about preventing breast cancer. The press release from the Cleveland Clinic is deceptive. It makes claims about the work that are irresponsible, misleading, and potentially dangerous. The Cleveland Clinic should be ashamed.And thus the Cleveland Clinic is the winner of this edition of the Overselling the Microbiome Award.
