Researchers in Brazil have found microplastics in human brain tissue, a new study published on Monday in the American Medical Association's journal JAMA reveals . Microplastics pollution has emerged in recent years as a growing environmental and health concern. Tiny pieces of plastic measuring between 0.0055 and 0.025 millimeters (0.00021 to 0.00098 of an inch) in size were previously detected in various human tissues and in the bloodstream. Their presence in the brain, however, up until [...]

A recent study, based on autopsies, detected microplastics in the olfactory bulbs, the smell centers of the human brain. The study revealed that these tiny floating microplastics in the air entered the brain likely through breathing. The latest study published in Jama Network Open that analyzed the olfactory bulbs of 15 deceased individuals using micro-Fourier transform infrared spectroscopy found the presence of microplastics in the olfactory bulbs of 8 individuals. "The presence of [...]

Researchers in Germany and Brazil say that 8 out of 15 autopsied adults had microplastics detected within their brain's smell centers, the olfactory bulb.   The particles were likely breathed in over a lifetime, since tiny floating microplastics are ubiquitous in the air. Although microplastics have already been found in human lungs, intestines, liver, blood, testicles and even semen, it had long been thought that the body's protective blood-brain barrier might keep the [...]

A study led by Brazilian researchers has produced a detailed description of the morphology of the nerves in the liver and how they control production of glucose when the organism is under stress. This process is known as hepatic gluconeogenesis. It is a key metabolic function of the liver that helps maintain a normal blood sugar level, especially when fasting and at times of high energy needs.  An article on the study, which entailed experiments with mice, is published in the [...]

A study involving 92 socioeconomically vulnerable elderly women compared the efficacy of different low-cost community-based exercise programs to improve and/or maintain cardiovascular and functional parameters, such as waist circumference, blood pressure, and above all arterial stiffness, a risk factor for atherosclerosis. An article describing the results is published in the European Journal of Preventive Cardiology. The main conclusion is that high-intensity interval training (HIIT) [...]

A mouse study suggests so, but the link is far from established in humans. Research over the years has suggested intermittent fasting has the potential to improve our health and reduce the likelihood of developing cancer. So what should we make of a new study in mice suggesting fasting increases the risk of cancer? The @ohyilmaz lab led by Shinya Imada and @KhawaledSaleh demonstrates the benefits and downside of fasting. They’ve discovered that fasting helps intestinal stem cells [...]

A group of Brazilian researchers has found a potential target for novel therapeutic strategies to combat fungal infections – more specifically, those caused by Aspergillus fumigatus. An article reporting the discovery is published in the journal Communications Biology. This species and other Aspergillus fungi are responsible for complications such as invasive pulmonary aspergillosis (IPA), a potentially fatal infection that can only occur in patients with weakened immune systems, [...]

While previous studies have linked intermittent fasting to benefits such as reductions in weight and dementia risk, new research in mice points to a potential downside of periodic food abstinences: an increase in the risk of cancer. The discovery follows a previous study that found fasting in mice led to a boost in the regenerative capabilities of their intestinal stem cells, protecting against injury and inflammation. Now an international team of researchers have determined this increase [...]
