In the downstream processing of antibody-based therapeutics, ultrafiltration/diafiltration (UF/DF) is commonly applied for concentration and buffer exchange in the final formulation. For a given molecule, various factors such as membrane type, feed flux, and transmembrane pressure (TMP) can significantly influence the performance of UF/DF, impacting yield, buffer exchange efficiency, and product quality. Conventional membrane pore size selection is based on product molecular weight to ensure high retention.

Diazepam, a widely prescribed benzodiazepine, is frequently used for the management of alcohol withdrawal syndrome, anxiety, seizures, and muscle spasms. Its monitoring is critical due to its potential for abuse and the therapeutic importance of its metabolite nordiazepam. A sustainable and environmentally friendly high-performance liquid chromatography method was developed and validated for the quantification of diazepam and its active metabolite nordiazepam in human plasma samples.

Associative phase separation (complex coacervation) in liquid-liquid phase separation (LLPS) involves the separation of multiple substances into concentrated and dilute phases by electrostatic interactions. Simple phase separation (simple coacervation) occurs when the hydrophilicity and hydrophobicity of a single molecule change dramatically in response to a specific stimulus. Simple coacervation arises from the lower critical solution temperature (LCST)- and upper critical solution temperature (UCST)-type phase separations in aqueous media containing temperature-responsive polymers.

Participating in long-term protests against government actions can affect protesters' mental health and expose protesters to potentially morally injurious events (PMIEs), such as the betrayal by leaders they once trusted. This study aimed to shed light on the potential psychological buffers against the deleterious effects of exposure to PMIEs of betrayal among protesters and to examine the moderating role of belongingness in the relationships between protesters' exposure to PMIEs and stress, PTSD and depression levels. The study sample comprised 4036 Israeli protesters (= 54.
