Caecilians are limbless amphibians that can be easily mistaken for snakes. Though caecilians are only distantly related to their reptilian cousins, researchers in a study appearing July 3 in the journal iScience describe specialized glands found along the teeth of the ringed caecilian (Siphonops annulatus), which have the same biological origin and possibly similar function to the venom glands of snakes. As such, caecilians may represent the oldest land-dwelling vertebrate animal with oral venom glands.
A new study published in The Journal of Physiology has shown that misfolded protein build-up in the gut could contribute to the development of Alzheimer's-like symptoms in mice. This could suggest a new treatment approach for Alzheimer's disease that would target the gut before symptoms of cognitive deficits appear in patients.
There is a considerable overlap between vascular and Alzheimer's disease (AD) risk factors. In addition, incident stroke approximately doubles the risk of developing AD. Oxidative stress is significantly involved in the pathogenesis of AD and suffers a dramatic increase in the setting of acute ischemic stroke, especially in cardioembolic stroke, followed by lacunar stroke, as shown in a previous study. Dampening this oxidative burst could delay the onset of subsequent dementia in stroke survivors.
In a new meta-study, experts from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have published ground-breaking findings on the effects of climate change for fish stock around the globe.
New research published today in The Journal of Physiology shows that 12 weeks of easy-to-administer passive stretching helps improve blood flow by making it easier for your arteries to dilate and decreasing their stiffness.
Eat a slab of steak and your resident gut bacteria get to work immediately to break it down. But new research shows that a metabolic byproduct, called TMAO, produced in the process can be harmful to the lining of arteries, making them age faster.
Toyohashi University of Technology has discovered that the difference in the ability to hear and distinguish English words including L and R, which are considered difficult for Japanese people, appears in pupillary responses. The research team conducted experiments to simultaneously measure the size of the pupil while playing English words in combinations such as "Light" and "Right", and clarified that it is possible to objectively estimate the ability to distinguish English words from the eyes.
The aim of this study was to compare the effects of 4-weeks of Traditional Resistance Training versus Plyometric Jump Training programs on the muscular fitness of sedentary and physically inactive participants.
Changes in blood platelets triggered by COVID-19 could contribute to the onset of heart attacks, strokes, and other serious complications in some patients who have the disease, according to University of Utah Health scientists. The researchers found that inflammatory proteins produced during infection significantly alter the function of platelets, making them "hyperactive" and more prone to form dangerous and potentially deadly blood clots.
Researchers from Osaka University developed a novel vaccine that removes senescent T cells from adipose tissues. They showed that vaccinated obese mice had improved glucose tolerance and insulin resistance without showing severe adverse events. These findings could help develop a novel therapeutic tool.
