This study explored the association between different cooking fuel types and the risk of cancer and all-cause mortality among seniors constructing Cox regression models. Data were obtained by linking waves of 6, 7, and 8 of the Chinese Longitudinal Healthy Longevity Survey, which included a total of 7,269 participants who were 65 years old and over. Cooking fuels were categorized as either biomass, fossil, or clean fuels. And the effects of switching cooking fuels on death risk were also investigated using Cox regression models. The results indicate that, compared with the users of clean fuels, individuals using bio...

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. Aging slowly...

In conclusion, this study confirms that innate immune training can be induced in aging healthy individuals as well as critically ill sepsis patients. We found that innate immune training can be induced regardless of age and there was no substantive difference in the immune trained phenotype as a function of age. We employed β-glucan as our immune training stimulus. The ability of glucan to induce the trained phenotype suggests that it may be possible to pharmacologically induce the immune trained phenotype in aging human immunocytes.

This study may have important implications for preventing cell senescence and aging-induced tendinopathy, as well as for the selection of novel therapeutic targets of chronic tendon diseases. Our results showed that the treatment of bleomycin, a DNA damaging agent, induced rat patellar TSC (PTSC) cellular senescence. The senescence was characterized by an increase in the senescence-associated β-galactosidase activity, as well as senescence-associated changes in cell morphology. On the other hand, rapamycin could extend lifespan in multiple species, including yeast, fruit flies, and mice, by decelerating DNA damage ...

The Functional and Molecular Effects of Doxycycline Treatment on Borrelia burgdorferi Phenotype
In this study, we aimed to identify gene expression patterns associated with the survival and re-growth of B. burgdorferi in the antibiotic environment. While a similar study in which RNASeq was applied to antibiotic treatment of B. burgdorferi was conducted (Feng et al., 2015), several important distinctions between that study and ours should be made. In that report by Feng et al, in vitro-cultured Bb were treated with either doxycycline or amoxicillin (50 μg/mL) for 6 days and then subjected to RNASeq, with comparison to the untreated control. Genes that were up-regulated by 2-fold or more were ascribed significan...

In conclusion, in the Framingham Heart Study population, in the last 30 years, disease duration in persons with dementia has decreased. However, age-adjusted mortality risk has slightly decreased after 1977-1983. Consequences of such trends on dementia prevalence should be investigated. Recent Research on the Benefits of Exercise in Later Life https://www.fightaging.org/archives/2018/04/recent-research-on-the-benefits-of-exercise-in-later-life/ A sizable body of work points to the ability of older individuals to continue to obtain benefits through regular physical activity, and particularly in the case ...

Stem Cells for Cell-Based Therapies
The world of stem cells We know the human body comprises many cell types (e.g., blood cells, skin cells, cervical cells), but we often forget to appreciate that all of these different cell types arose from a single cell—the fertilized egg. A host of sequential, awe-inspiring events occur between the fertilization of an egg and the formation of a new individual: Embryonic stem (ES) cells are also called totipotent cells. The first steps involve making more cells by simple cell division: one cell becomes two cells; two cells become four cells, etc. Each cell of early development is undifferentiated; that is, it is...
