Macrolactin A (McA) is a secondary metabolite produced by Bacillus species. It has been known for its antimicrobial properties since the late 1980s, although the exact mechanism of its antibacterial activity remains unknown. In this study, we have found that McA is an inhibitor of protein synthesis in bacteria.

Fermented milk products (FMP) have been consumed by humans for millennia and the health benefits are no longer to be demonstrated. Although the manufacturing procedure have been industrialized, FMPs are still produced traditionally in many parts of the world with variable manufacturing procedures and unknown sanitary conditions. In this study, we aimed at comparing the physico-chemical properties of industrial and traditional FMPs from France and Mali as well as their microbial diversity.

The current work focuses on the creation of novel derivatives of the quinazolinone ring system, with various substituted thiophene, thienopyrimidine, and thienopyridine scaffolds 3a,b-11. Employing the standard MTT assay, every target compound's antiproliferative efficacy was evaluated in comparison with doxorubicin against both normal WI-38 cells and various cancer cell lines. Derivatives 6, 8a, and 8b demonstrated the most potent activity, alongside their safety profiles against WI-38.

Analyzing the chemical composition of different kinds of acrylic cement is necessary to understand their properties and suitability for curing bone defects. Conducting various chemical tests can give valuable insight into the composition, viscosity, and performance characteristics of each kind of cement, Therefore, our study aimed to find safety standards and the effectiveness of these products for medical applications. The polymeric characterization was determined by Nuclear Magnetic Resonance (H-NMR) spectroscopy and Fourier-transform infrared spectroscopy (FTIR).

Tenofovir alafenamide (TAF) is currently administered orally to patients for treatment of chronic hepatitis B virus infection and as a part of a combination therapy for human immunodeficiency virus (HIV) infection. A long-acting delivery system could provide several advantages as a formulation strategy for this drug including improved patient adherence, convenience, more consistent drug levels and potentially fewer side effects. To date, the vast majority of polymer-based long-acting delivery systems have been prepared from poly(lactide--glycolide) [1].
