Saturating bioactive glass with silver sustains the metal’s antimicrobial properties and reduces biofilm formation, researchers at the University of Birmingham, U.K., found. Their study, published in Biofilm, demonstrated that specific preparation, storage and application techniques minimize the transformation of silver ions to silver chloride that typically reduces silver’s healing properties over time.
The Institute for Drug Research has patented pyrrolidine antiviral compounds acting as 3C-like proteinase (3CLpro; Mpro; nsp5) (SARS-CoV-2; COVID-19 virus) inhibitors.
Having caused over 6.2 million deaths globally ongoing, the COVID-19 pandemic since 2020 continues to pose a serious public health challenge. While the SARS-CoV-2 receptors angiotensin-converting enzyme 2 (ACE2) and transmembrane protease serine 2 play requisite roles in permitting the initial infection, up to 10 proviral host factors have also been determined to play crucial roles in controlling the viral replication, but most are not pharmacologically targetable.
Acinetobacter baumannii is commonly isolated from organ fluids of infected patients. Given that A. baumannii is inherently resistant to multiple antibiotics, new categorical antibiotics are needed that target a narrow, not broad, spectrum of bacteria.
A new study has shown that a uterine bacterium is one cause of endometriosis and that preventing the infection could prevent development of the pathology, in which tissue similar to the lining of the uterus grows in the abdominal cavity.
Two new polio vaccine candidates designed to prevent the emergence of vaccine-derived virulent polioviruses have been shown to induce immune responses in mice, raising the possibility of eradicating the virus. For that to happen, the transmission of all poliovirus serotypes must be blocked. However, the vaccine used to control polio prevents disease but does not stop transmission, enabling the virus to mutate and regain virulence.
La Crosse virus (LACV) is one of the most common causes of arboviral encephalitis in children, which causes CNS damage owing to infection in children, but not adults. LACV pathology indicates significant breakdown of the blood-brain barrier, which is strengthened during developmental transition from child to adult.
For Jeff Galvin, the CEO and founder of newly launched Addimmune Inc., HIV is not a condition that’s in the rearview mirror. It needs a functional cure to save lives, make people healthier and save money that need not have been spent. People wonder why it’s worth bothering to cure HIV, Galvin told BioWorld, when they are taking their medications every day and they are feeling pretty close to normal. But it’s not close for Galvin, who noted that there are side effects from taking the pills that can cause headaches, fatigue, nausea and diarrhea.
