Behaviours and psychological symptoms of childhood dementia: two cases of psychosocial interventions.

Childhood dementias are a group of rare, fatal neurodegenerative disorders, characterised by global cognitive decline, loss of previously acquired developmental skills and behaviours and psychological symptoms of dementia (BPSD). Batten disease, or neuronal ceroid lipofuscinosis, and Sanfilippo syndrome, or mucopolysaccharidosis type III, are two of the more common forms of childhood dementia disorders worldwide. While psychosocial interventions are the best available therapeutic approach for BPSD management in adult-onset dementia, there is very limited literature or clinical experience in the context of childhood dementia.

O-PTIR spectroscopy for characterizing active pharmaceutical ingredient specific particle size distributions of nasal spray suspension products.

Evaluation of the particle size distribution (PSD) of active pharmaceutical ingredients (APIs) in nasal suspension products is challenging due to the presence of both API and excipients. To characterize these intricate formulations, it is essential to have sophisticated analytical methods that offer high spatial resolution and the ability to chemically pinpoint and map out the presence of API particles. However, such advanced techniques have not been documented for nasal formulations yet.

Extracellular vesicles as the next-generation modulators of pharmacokinetics and pharmacodynamics of medications and their potential as adjuvant therapeutics.

Background And Main Body: Pharmacokinetics (PK) and pharmacodynamics (PD) are central concepts to guide the dosage and administration of drug therapies and are essential to consider for both healthcare professionals and researchers in therapeutic planning and drug discovery. PK/PD properties of a drug significantly influence variability in response to treatment, including therapeutic failure or excessive medication-related harm. Furthermore, suboptimal PK properties constitute a significant barrier to further development for some candidate treatments in drug discovery.

Discovery of novel 2-substituted 2, 3-dihydroquinazolin-4(1H)-one derivatives as tubulin polymerization inhibitors for anticancer therapy: The in vitro and in vivo biological evaluation.

A series of novel 2-substituted 2, 3-dihydroquinazolin-4(1H)-one derivatives were designed, synthesized and estimated for their in vitro antiproliferative activities against HepG2, U251, PANC-1, A549 and A375 cell lines. Among them, compound 32 was the most promising candidate, and displayed strong broad-spectrum anticancer activity. The mechanism studies revealed that compound 32 inhibited tubulin polymerization in vitro, disrupted cell microtubule networks, arrested the cell cycle at G2/M phase, and induced apoptosis by up-regulating the expression of cleaved PARP-1 and caspase-3.
