In conclusion, the longevity-associated genotype of FLT1 may confer increased lifespan by protecting against mortality risk posed by hypertension. We suggest that FLT1 expression in individuals with longevity genotype boosts vascular endothelial resilience mechanisms to counteract hypertension-related stress in vital organs and tissues.

This study showed a negative relationship between the gaps and the number of senescence cells. Moreover, we found a similar reduction in 30-month-old naturally and 7-month-old D-gal-induced aging rats. Given these consistent data from different eukaryotic organisms, it suggests that the Youth-DNA-GAP is a marker of phenotype-related aging degree

In this study, we developed the first epigenetic clock for domesticated sheep (Ovis aries), which can predict chronological age with a median absolute error of 5.1 months. We have discovered that castrated male sheep have a decelerated aging rate compared to intact males, mediated at least in part by the removal of androgens.
Furthermore, we identified several androgen-sensitive CpG dinucleotides that become progressively hypomethylated with age in intact males, but remain stable in castrated males and females. Comparable sex-specific methylation differences in MKLN1 also exist in bat skin and a range of mouse tissu...

20 Medical Technology Advances: Medicine in the Future – Part II.
Nanorobots swimming in blood vessels, in silico clinical trials instead of experimenting with drugs on animals and people, remote brain surgeries with the help of 5G networks – the second part of our shortlist on some astonishing ideas and innovations that could give us a glimpse into the future of medicine is ready for you to digest. Here, we’re going beyond the first part with medical tricorders, the CRISPR/Cas-9 gene-editing method, and other futuristic medical technologies to watch for.

We examined 9293 individuals from the Copenhagen General Population Study using nuclear magnetic resonance spectroscopy measurements of total cholesterol, free- and esterified cholesterol, triglycerides, phospholipids, and particle concentration. Fourteen subclasses of decreasing size and their lipid constituents were analysed: six subclasses were very low-density lipoprotein (VLDL), one intermediate-density lipoprotein (IDL), three low-density lipoprotein (LDL), and four subclasses were high-density lipoprotein (HDL). Remnant lipoproteins were VLDL and IDL combined.
Mean nonfasting cholesterol concentration was 72â...

This study shows that mRNA levels of the aging related lamin A splice variant progerin, associated with premature aging in HGPS, were significantly upregulated in subjects with BMI ≥ 25 kg/m2. Moreover, our data revealed a significantly positive correlation of BMI with progerin mRNA. These data provide to our knowledge for the first-time evidence for a possible involvement of progerin in previously observed accelerated aging of overweight and obese individuals potentially limiting their longevity. Our results also showed that progerin mRNA was positively correlated with C-reactive protein (CRP). This might suggest an ass...

This study defines a new clinically relevant concept of T-cell senescence-mediated inflammatory responses in the pathophysiology of abnormal glucose homeostasis. We also found that T-cell senescence is associated with systemic inflammation and alters hepatic glucose homeostasis. The rational modulation of T-cell senescence would be a promising avenue for the treatment or prevention of diabetes.

In conclusion, reduction of LDL-C to less than 50 mg/dl seems safe and provides greater CV benefits compared with higher levels. Data for achieved LDL-C lower than 20-25 mg/dl is limited, although findings from the above mentioned studies are encouraging. However, further evaluation is needed for future studies and post-hoc analyses.

In this study, researchers put some numbers to the correlation, and improve on previous attempts to rule out wealth and other effects as significant contributing causes.
A study finds that a Chinese policy is unintentionally causing people in northern China to live 3.1 years less than people in the south, due to air pollution concentrations that are 46 percent higher. These findings imply that every additional 10 micrograms per cubic meter of particulate matter pollution reduces life expectancy by 0.6 years. The elevated mortality is entirely due to an increase in cardiorespiratory deaths, indicating that air poll...

In conclusion, we found that IS status was associated with a significant increase in Hannum DNA methylation, likely as a consequence of the accumulation of cardiovascular risk factors, and near signification with Horvath method. Patients with IS were biologically older than controls, a difference that was more obvious in young stroke. This could open up the possibility of useful new biomarker of stroke risk.

We examined the engraftment and differentiation of alkaline phosphatase-positive NSCs expanded from the postnatal subventricular zone (SVZ), 3 months after grafting into the intact young or aged rat hippocampus. Graft-derived cells engrafted robustly into both young and aged hippocampi. Although most graft-derived cells pervasively migrated into different hippocampal layers, the graft cores endured and contained graft-derived neurons.
The results demonstrate that advanced age of the host at the time of grafting has no major adverse effects on engraftment, migration, and differentiation of grafted subventricular zone...

Update: Baltimore, Safety in AF ablation, Podcasts, and some personal notes
On Baltimore:
Human beings rioting in the streets of an American city forced cancellation of an important cardiology meeting. This is a vivid example that doctors do not practice in a vacuum. We are connected to this world. Here in Louisville, just a few miles north, an HIV crisis runs amok because of IV drug use. Despair. Inequality. These are no small things. What bothers me most about our healthcare system is the waste. We burn money. If we stopped doing that, we would have more to do for the less fortunate. I make a call out to every day physicians to stop burning money. Medicine Can’t Ignore Baltimore and Fergus...
