Antibodies can prevent bacterial surface proteins from entering host cells

Antibodies can prevent bacterial surface proteins from entering host cells

Using Bartonella henselae bacteria, scientists from Goethe University, Frankfurt University Hospital, the Paul Ehrlich Federal Institute for Vaccines and Biomedicine in Langen and the University of Oslo have shown for the first time that antibodies can prevent the formation of certain surface proteins of bacterial pathogens. entering host cells. The findings are important for the …

Advances in nasal antibiotic delivery

In a recent study published in Journal of Drug Delivery Science and Technologyresearchers reviewed advances and challenges in intranasal antibiotic delivery. Antibiotics are substances that act against bacteria to prevent or treat infectious diseases. The overuse of antibiotics is particularly contributing to increasing bacterial resistance. As a result, oral administration of antibiotics was prevalent and …

Researchers receive $9 million grant to study how 'jumping genes' affect Alzheimer's disease

Researchers receive $9 million grant to study how ‘jumping genes’ affect Alzheimer’s disease

Scientists have identified several gene mutations that cause or contribute to the onset of Alzheimer’s disease. But many scientists suspect that other DNA changes may help lead to Alzheimer’s-related brain cell damage and lead to symptoms of confusion and memory loss in patients. In particular, scientists want to understand how segments of DNA that jump …

Consuming green tea extract can lower blood sugar and improve gut health

Consuming green tea extract can lower blood sugar and improve gut health

New research in people with heart disease risk factors has shown that consuming green tea extract for four weeks can lower blood sugar and improve gut health by reducing inflammation and reducing “leaky gut.” The researchers said this is the first study to evaluate whether the health risks associated with a condition known as metabolic …

Bacterial infections cause sperm dysfunction through their outer membranous sacs

Infertility rates continue to rise worldwide and are currently estimated to affect up to 170 million people. Male factors contribute to at least half of infertility cases, including hormonal abnormalities, problems with sperm transport or entry into the fallopian tubes, impaired sperm production, and male reproductive tract infections (MRTIs). MRTIs are responsible for about 10% …

Improved nanoscale drills kill bacteria directly and revive existing antibiotics

Molecular machines that kill infectious bacteria have been designed to work with a more clinically useful light source of energy. The latest iterations of these synthetic nanoscale or molecular machinery (MM), developed by researchers at Rice University, are activated by visible light rather than ultraviolet (UV), as in earlier versions. Tests of burn-related bacterial infections …
