Summary: The aim of this study was to find a bacteria isolate that is tolerant to cadmium (Cd2+) and has the ability to remediate contaminated soil from a KNO3 processing unit. Out of 19 isolates, one isolate, identified as Enterobacter hormaechei SFC3 through molecular characterization, showed superior tolerance to Cd2+ compared to others. The identified strain contained 55% GC content and 45% AT content. The wild and acridine orange mutated E. hormaechei SFC3 exhibited excellent resistance to Cd2+ up to a concentration of 1500 μg mL(-1). Furthermore, both the wild and mutated strains showed significant Cd2+ remediation capability. The findings suggest that E. hormaechei SFC3 is a promising candidate for microbial remediation of Cd2+ contamination.

Summary: The study demonstrates that Brucein D (BD) inhibits Akt-driven signaling events in multiple myeloma (MM) cells, leading to decreased cell viability and proliferation. BD induces apoptosis and reduces the expression of antiapoptotic proteins in MM cells. Additionally, BD reverses the activation of kinases, including Akt, and regulates chemoresistance through the modulation of Akt phosphorylation.

Summary: Material modification with low surface energy can achieve lower surface free energy on micro-and nano-rough structures, which is crucial for developing superhydrophobic surfaces. In this study, attapulgite (APT) was modified with alkylamine, alkylammonium salt, and stearic acid, and the interaction between low surface materials and attapulgite was explained. The results showed that the hydrophobicity of APT was significantly modified by the modifiers, and the surface free energy of the composites first decreased and then increased with increasing molecular number of low surface energy monomers.

Summary: The main aim of this study was to prepare a drug-drug coamorphous system to improve the physiochemical properties, solubility and stability of Apremilast and Indomethacin. Various solid-state characterization techniques were used to characterize the prepared system. Molecular level interactions were studied using molecular modeling and ATR-FTIR and 1H NMR. Solubility and dissolution studies showed the benefits of the coamorphous system. The system was found to be stable for a period of five months. Permeation study also demonstrated improved flux for both drugs compared to their crystalline forms. The coamorphous system showed anti-psoriatic and anti-melanogenic activity based on molecular docking results. Overall, the developed CAM-based supersaturated system exhibited improved physicochemical properties and physical stability.
