Plant-based diets are best … or are they?
This study is also a reminder that the health impact of a particular intervention (such as diet) may not be easy to predict or explain. In most cases, the risk of stroke and heart disease tend to rise or fall together, but that wasn’t the case in this research.
Beware the study’s limitations
This study linking a vegetarian diet with a higher risk of hemorrhagic stroke has a number of important limitations that should temper the concerns of vegetarians.
The study was observational. That means it simply observed what happened among different people who followed different diets over time, without being able to account fo...

In this study, AT1-AAs were detected in the sera of patients with peripheral arterial disease (PAD) and the positive rate was 44.44% vs. 17.46% in non-PAD volunteers. In addition, analysis showed that AT1-AAs level was positively correlated with PAD. To reveal the causal relationship between AT1-AAs and vascular aging, an AT1-AAs-positive rat model was established by active immunization. The carotid pulse wave velocity was higher, and the aortic endothelium-dependent vasodilatation was attenuated significantly in the immunized rats. Morphological staining showed thickening of the aortic wall. Histological examination showe...

CDK5 as a Target to Reduce Cell Death Following Ischemic Stroke
In this study, we synthesized a membrane-permeable peptide (Tat-CDK5-CTM) that specifically disrupts the binding of CDK5 and NR2B and then leads to the degradation of CDK5 by a lysosome-mediated pathway.
We found that the administration of Tat-CDK5-CTM not only retards calcium overload and neuronal death in oxygen and glucose deprivation (OGD)-treated neurons but also reduced the infarction area and neuronal loss and improved the neurological functions in MCAO (middle cerebral artery occlusion) mice. The peptide-directed lysosomal degradation of CDK5 is a promising therapeutic intervention for stroke.

Gore CARDIOFORM ASD Cleared in Europe for Atrial Septal Defects
Gore won the European CE Mark for its GORE CARDIOFORM ASD Occluder, a device designed for percutaneous, transcatheter closure of ostium secundum atrial defects (ASDs). The occluder recently completed a clinical study involving 125 patients with ASD, ranging from 2 to 84 years of age, all of whom were successfully implanted with the GORE CARDIOFORM ASD and maintained closure six months later.
The device is made of two discs that make contact with the tissue walls on both sides of the opening and, when engaged, come together to block the passage of blood between the atria. It was recently approved by the FDA for ASD, as ...

A 40-Something male with a " Seizure, " Hypotension, and Bradycardia
This is by one of ouroutstanding 3rd year residents, Aaron Robinson, with some edits and comments by SmithEMS responded to a reported seizure in a 42 year old male. Per bystanders, he went down after some intense sporting activity, and had “shaking” type movement. He reports no personal or familial history of seizures.One of our EMS Fellows along with a Senior EM Resident were on duty that evening, and arrived on the scene with the Fire Department. When the physicians approached him, he was ashen, diaphoretic, and appeared in shock. Fire was able to obtain a BP of 60/palp and a pulse in the 40s. The physicians quickly ...

In conclusion, older adults exhibited decreased markers of UPR activation and reduced coordination with autophagy and SC-associated gene transcripts following a single bout of unaccustomed resistance exercise. In contrast, young adults demonstrated strong coordination between UPR genes and key regulatory gene transcripts associated with autophagy and SC differentiation in skeletal muscle post-exercise. Taken together, the present findings suggest a potential age-related impairment in the post-exercise transcriptional response that supports activation of the UPR and coordination with other exercise responsive pathways (i.e....

Conversion of Glial Cells into Neurons as an Approach to Regeneration in the Brain
The authors of today's research report on success in use of a gene therapy to convert glial cells into neurons in a living mouse brain, and thereby improve the normally limited recovery that takes place following brain injury, such as that caused by a stroke. A number of research groups are investigating this class of approach to enhance regeneration in the brain, an organ that has little capacity to repair itself. The capacity that does exist is generated by neural stem cells that, arguably, continue to produce new neurons at some pace throughout life. As for all stem cell populations, activity declines with age, however....

In this study, researchers studied 438,952 participants in the UK Biobank, who had a total of 24,980 major coronary events - defined as the first occurrence of non-fatal heart attack, ischaemic stroke, or death due to coronary heart disease. They used an approach called Mendelian randomisation, which uses naturally occurring genetic differences to randomly divide the participants into groups, mimicking the effects of running a clinical trial.
People with genes associated with lower blood pressure, lower LDL cholesterol, and a combination of both were put into different groups, and compared against those without thes...

Lower LDL Cholesterol and Blood Pressure Over a Lifetime Correlate with Greatly Reduced Risk of Cardiovascular Disease

Forever Healthy Foundation Begins Publishing Risk/Benefit Analyses of Potential Treatments for Aging
Very few of the presently available interventions for aging are forms of rejuvenation, and of these most are debatable or have small, unreliable effects. Beyond senolytic drugs to clear some fraction of senescent cells from aging tissues, an approach that is producing sizable, reliable effects in animal studies and that will soon enough become a major part of healthcare for the old, other present treatments can only be argued to be forms of rejuvenation. Either they are not addressing root cause damage, or their effect sizes are so marginal as to make it unclear as to whether anything interesting is taking place. Consider ...

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 72...

In this study, we identify a link between members of the genus Veillonella and exercise performance. We observed an increase in Veillonella relative abundance in marathon runners postmarathon and isolated a strain of Veillonella atypica from stool samples. Inoculation of this strain into mice significantly increased exhaustive treadmill run time.
Veillonella utilize lactate as their sole carbon source, which prompted us to perform a shotgun metagenomic analysis in a cohort of elite athletes, finding that every gene in a major pathway metabolizing lactate to propionate is at higher relative abundance postexercise. Us...

First Cryopreservation Following Use of Assisted Death Legislation in California
Simple human dignity and self-ownership demands the right to end one's own life on one's own terms, and to be able to help others achieve this goal where they are not capable of doing so themselves. Yet these acts remain forbidden to most people in most parts of the world. Painless, effective euthanasia requires medical assistance, and providing that service remains largely illegal. This state of affairs is slowly starting to change in the US, however, and so late last year the first cryopreservation following voluntary euthanasia took place.
Cryopreservation is the only presently available end of life option that o...
