Scientists Reveal 51 Mutations Linked to Changes in ALS Risk
Publicado em 03 novembro 2024
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 [...]

Fighting Back Against Fungal Pathogens
Publicado em 13 setembro 2024Two 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 [...]ver notícia -
Can This 'Functional Bread' Prevent Asthma?
Publicado em 20 junho 2024Asthma 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 [...]ver notícia -
Previous Zika Infections Increase the Risk of Severe Dengue
Publicado em 08 fevereiro 2024Climate 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 [...]ver notícia -
SARS-CoV-2 Can Infect Liver Cells, Impairing Glucose Metabolism
Publicado em 20 julho 2023New 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 [...]ver notícia -
How a Parasite Manipulates a Host's Defenses to Stay Alive
Publicado em 23 maio 2023Sand 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 [...]ver notícia -
Establishing a Link Between Cannabinoids and Infant Respiratory Problems
Publicado em 01 maio 2023How 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 [...]ver notícia -
Exercise Preserves Physical Fitness During Aging: Scientists Are Beginning to Understand Why
Publicado em 06 janeiro 2023Regular exercise is known to have numerous health benefits for people who are aging. Exercise can help to improve strength, flexibility, and balance, which can, in turn, improve overall physical function. Many of the health problems that seem to come with age can be delayed by exercise. Though the cellular mechanisms underlying the relationship between exercise, fitness, and aging have historically been poorly understood, scientists are beginning to understand them. In a [...]ver notícia -
Promising Epigenetic Treatment for Depression Works After One Dose
Publicado em 05 janeiro 2021Researchers affiliated with the University of Sao Paulo in Brazil have used epigenetic modulators to reduce stress-induced damage to neuroplasticity, and thus resolve symptoms of depression in rats. Whereas conventional antidepressants need to be taken repeatedly before they take effect, their current interventions worked after one dosage. Stress is known to alter certain epigenetic markers associated with neuroplasticity in the brain. In particular, it increases DNA methylation, a [...]ver notícia
