A Possible Protective Effect of IgA Against Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2) in Bronchoalveolar Lavage in COVID-19 Patients Admitted to Intensive Care Unit.

SARS-CoV-2 infection induces a humoral immune response, producing virus-specific antibodies such as IgM, IgG, and IgA. IgA antibodies are present at mucosal sites, protecting against respiratory and other mucosal infections, including SARS-CoV-2, by neutralizing viruses or impeding attachment to epithelial cells. Since SARS-CoV-2 spreads through the nasopharynx, the specific IgAs of SARS-CoV-2 are produced quickly after infection, effectively contributing to virus neutralization.

Development of Biodegradable and Recyclable FRLM Composites Incorporating Cork Aggregates for Sustainable Construction Practices.

Reducing energy consumption in the building sector has driven the search for more sustainable construction methods. This study explores the potential of cork-modified mortars reinforced with basalt fabric, focusing on optimizing both mechanical and hygroscopic properties. Six mortar mixtures were produced using a breathable structural mortar made from pure natural hydraulic lime, incorporating varying percentages (0-3%) of cork granules () as lightweight aggregates.

The impact of lactose intolerance diagnosis: costs, timing, and quality-of-life.

Lactose intolerance (LI) is a very common condition but, despite many efforts of the Italian National Health Service to reduce diagnostic delay of chronic disorders and provide prompt treatments, its early diagnosis remains an unmet need. In addition, the COVID-19 pandemic has exacerbated this problem, due to the conversion of many public health services to COVID centers. This study aims to analyze the diagnostic journey of patients suffering from LI, taking into account the duration of the process, associated costs, and impact on quality of life.

WaSPred: A reliable AI-based water solubility predictor for small molecules.

A rapid and reliable evaluation of the aqueous solubility of small molecules is a hot topic for the scientific community and represents a field of particular interest in drug discovery. In fact, aqueous solubility significantly impacts various aspects that collectively influence a drug's overall pharmacokinetics, including absorption, distribution and metabolism. For this reason, in silico approaches that provide fast and cost-effective solubility predictions, can serve as invaluable tools in the early stages of drug development.
