A Review of Presently Popular Approaches for the Construction of Therapies to Slow or Reverse Aging
In conclusion, there are many anti-aging strategies in development, some of which have shown considerable promise for slowing down aging or delaying the onset of age-related diseases. From multiple pre-clinical studies, it appears that upregulation of autophagy through autophagy enhancers, elimination of senescent cells using senolytics, transfusion of plasma from young blood, neurogenesis and BDNF enhancement through specific drugs are promising approaches to sustain normal health during aging and also to postpone age-related diseases. However, these approaches will require critical assessment in clinical trials to determ...

In this study, senescent cell distribution and quantity in vastus lateralis muscle were examined in young human adults after a single bout of resistance exercise. To determine the effects of dietary protein availability around exercise on senescent cell quantity and macrophage infiltration of skeletal muscle, two isocaloric protein supplements (14% and 44% in calorie) were ingested before and immediately after an acute bout of resistance exercise, in a counter-balanced crossover fashion. An additional parallel trial was conducted to compare the outcome of muscle mass increment under the same dietary conditions after 12 wee...

aka Tropical Travel Trouble 008
Peer Reviewer Dr McBride ID physician, Wisconsin
TB affects 1/3rd of the population and one patient dies every 20 seconds from TB. Without treatment 50% of pulmonary TB patients will be dead in 5 years. In low to middle income countries both TB and HIV can be ubiquitous, poor compliance can lead to drug resistance and malnourished infants are highly susceptible. TB can be very complex and this post will hopefully give you the backbone to TB m...

Exploring the Utility of Decellularized Muscle Grafts in Animal Models
In this open access paper, researchers explore the utility of decellularized muscle grafts to repair severe injury. Decellularization is the process by which a donor tissue is cleared of cells, leaving behind the extracellular matrix. This intricate structure includes capillary networks and chemical cues to guide cells, line items that the research community has yet to reliably recreate when building tissue from scratch. Over the past decade, researchers have demonstrated the ability to repopulate decellularized tissue with patient-derived cells, a capacity that in principle allows for the production of patient-matched don...

Chondroitin and melanoma: How worried should you be?
Follow me on Twitter @RobShmerling
Chondroitin sulfate is among the most popular supplements in the world. It’s often taken in combination with glucosamine for joint disease — some take it for prevention, others to treat pain.
And yet, evidence that it actually works at all is limited at best. One review of the evidence suggested that of the few studies of chondroitin that were positive, nearly all were funded by makers of the supplement. Despite this, millions of people take it, many of my patients swear by it, and the lack of evidence doesn’t seem to be much of a concern to them. A frequent comment I hear is: “We...

In conclusion, most experimental data on immune changes with aging show a decline in many immune parameters when compared to young healthy subjects. The bulk of these changes is termed immunosenescence. Immunosenescence has been considered for some time as detrimental because it often leads to subclinical accumulation of pro-inflammatory factors and inflammaging. Together, immunosenescence and inflammaging are suggested to stand at the origin of most of the diseases of the elderly, such as infections, cancer, autoimmune disorders, and chronic inflammatory diseases. However, an increasing number of gerontologists have chall...

A Few Recent Advances in Tissue Engineering and Regenerative Medicine
The tissue engineering and regenerative medicine communities are too large and energetic to do more than sample their output, or note the most interesting advances that stand out from the pack. The publicity materials I'll point out here are a recent selection of items that caught my eye as they went past. Dozens more, each of which would have merited worldwide attention ten or fifteen years ago, drift by with little comment every year. The state of the art is progressing rapidly towards both the ability to build complex tissues from a cell sample, such as patient-matched organs for transplantation, and the ability to cont...

This study cohort is a healthy subset of the EpiPath cohort, excluding all participants with acute or chronic diseases. With a mediation analysis we examined whether CMV titers may account for immunosenescence observed in ELA.
In this study, we have shown that ELA is associated with higher levels of T cell senescence in healthy participants. Not only did we find a higher number of senescent cells (CD57+), these cells also expressed higher levels of CD57, a cell surface marker for senescence, and were more cytotoxic in ELA compared to controls. Control participants with high CMV titers showed a higher number of senes...

In this study, we demonstrate that irrespective of the derivation of CD8+ CD45RA+CD27- T cells, these primed cells exhibit a unique highly inflammatory secretory profile characteristic of the SASP, and we also provide evidence that ADAM28 can be used as a functional marker of senescence in CD8+ T cells. Furthermore, we show that the secretory phenotype in CD8+ CD45RA+CD27- T cells is controlled through p38 MAPK signalling, which contributes to age-associated inflammation.

In this study, we have shown that the lipid chaperones FABP4/FABP5 are critical intermediate factors in the deterioration of metabolic systems during aging. Consistent with their roles in chronic inflammation and insulin resistance in young prediabetic mice, we found that FABPs promote the deterioration of glucose homeostasis; metabolic tissue pathologies, particularly in white and brown adipose tissue and liver; and local and systemic inflammation associated with aging. A systematic approach, including lipidomics and pathway-focused transcript analysis, revealed that calorie restriction (CR) and Fabp4/5 deficiency result ...

Genetically Modified Skin Graft Works as Built-In Glucose Meter
Easy to use finger prick glucometers have helped diabetics to manage their disease and continuous glucose monitors that stay on the body for days at a time have made it even easier. Still, these will seem like technology from centuries past compared to the genetically engineered and grafted blood glucose sensor developed at the University of Chicago.
To achieve this, the team used the CRISPR technique to modify skin stem cells so that they incorporate a special gene from E. coli bacteria. This gene produces glucose/galactose-binding protein (GGBP), and as the name implies, it attaches itself to sugar.
In order to actually...

Baby Foreskin Is Being Used To Make Vaccines
Conclusion
Vaccine companies have regularly used blood and body parts from killed cows, dogs, worms, mice, chickens, human babies, monkeys, guinea pigs, rabbits, hamsters, rats, etc., to make these vaccines, so using foreskin from newborn babies may not surprise some. For many, it is appalling. [28]
Circumcisions fuel multi-billion dollar industries. If you see neonatal foreskin for sale, which is very easy to find on the internet, remember that these newborn children didn’t consent to being circumcised and they didn’t consent for their foreskin to be sold, used for research purposes, or to be injected into the people ...

Caring for your own wounds: Lessons from the burn unit
“Someone call for a body bag.”
These were words that I didn’t expect to hear on my final day of burn surgery at large metropolitan hospital. We had just planned on a routine burn excision and skin grafting. Our patient, Faith, was a seven-year-old girl with third-degree burns to 85 percent of her body from a house fire. We had been caring for her in the ICU for the past three weeks. She was doing well, with extubation planned in a few days. Her ten-year-old brother had also been in the house fire, with third-degree burns to 65 percent of his body. He, too, was still on the ventilator and sedated. Their father, who ha...

This study developed the first procedure for the removal of epithelium from the lung airway with the full preservation of vascular epithelium, which could be applied in vivo to treat diseases of lung epithelium. Whole lung scaffolds with an intact vascular network may also allow for recellularization using patient-specific cells and bioengineering of chimeric lungs for transplantation. In addition to the clinical potential, lung scaffolds lacking an intact epithelial layer but with functional vascular and interstitial compartments may also serve as a valuable physiological model for investigating (i) lung development, (ii)...
