Drinking more than eight alcoholic drinks per week is linked to a higher risk of brain lesions called hyaline arteriolosclerosis, which are linked to memory and thinking problems. The corresponding study was published in Neurology. "Heavy alcohol consumption is a major global health concern linked to increased health problems and death. We looked at how alcohol affects the brain as people get older. Our research shows that heavy alcohol consumption is damaging to the brain, which can [...]

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder in which neurons in the central nervous system that help control muscle movement start to die. This causes muscles to weaken, and eventually waste away. Movements like walking and talking degenerate first, but in most cases, other functions like breathing are eventually affected and the disorder gets worse. The disease is fatal to most people who are diagnosed within about five years of diagnosis. though some people survive for [...]

Two new research studies are addressing the rising threat of fungal infections, which can be very difficult to treat. One study has examined the cell walls of fungi to look for weaknesses, while another, unrelated paper identified a fungal gene that promotes virulence, and could be an excellent drug target. Reporting in The Journal of Physical Chemistry Letters, scientists used techniques called wide- and small-angle neutron scattering diffraction and spectroscopy to look at lipids, or fats [...]

Asthma is a very common respiratory disorder that can be life-threatening in extreme cases. Scientists have now developed a bread that contains a very specific type of brewer's yeast that aims to prevent the development of asthma. This strain of brewer's yeast, called Saccharomyces cerevisiae UFMG A-905, has been shown to have probiotic properties that were able to relieve the symptoms of asthma in a mouse model. Now, the researchers are aiming to test this bread in human clinical [...]

Climate change is raising temperatures around the world, and mosquitoes are on the move. As their territories expand, these pests are brining diseases like dengue with them, and cases of the viral illness are on the rise in many places. There are also newly emerging viruses to contend with, like the pandemic virus SARS-CoV-2 or the less pervasive but still threatening Zika virus, which has caused major outbreaks in several countries and is still considered a [...]

New research has shown that SARS-CoV-2, the virus that causes COVID-19, can infect liver cells, which are also known as hepatocytes. The hepatocyte infection triggers glucose production, which leads to a condition called hyperglycemia that is similar to diabetes, in patients who are have been hospitalized. This occurs even when the patient's blood glucose levels are normal poor to their hospital admission. The findings have been reported in the Proceedings of the National Academy of [...]

Sand flies transmit over 20 species of infectious Leishmania parasites, which infect host macrophages and other immune cells. Various factors can have an influence on whether or not infections are asymptomatic. Various forms of leishmaniasis can occur and lead to a wide variety of symptoms, such as sores. Leishmania parasites are known as 'master manipulators' of their hosts, and they have many different ways to evade the host immune response and promote parasite [...]

How much of an impact can cannabis exposure have on newborn babies? This is what a recent study published in the British Journal of Pharmacology hopes to address as they examine how cannabis use can lead to complications with newborn babies, specifically pertaining to symptoms that could lead to infant death syndrome. “Cannabis and derivatives have been legalized or decriminalized in several countries, and their consumption has increased,” said Dr. Luis Gustavo Patrone, who is [...]
