We present two cases wherein vitiligo developed after the onset of halo formation involving congenital melanocytic nevi to emphasize the possibility of this finding as a potential albeit unusual presentation of vitiligo.

Purpose: Improving drug solubility is crucial in formulating poorly water-soluble drugs, especially for oral administration. The incorporation of drugs into mesoporous silica nanoparticles (MSN) is widely used in the pharmaceutical industry to improve physical stability and solubility. Therefore, this study aimed to elucidate the mechanism of poorly water-soluble drugs within MSN, as well as evaluate the impact on the dissolution and physical stability.

α-Halo borides are generally constructed Matteson homologation, and the synthesis of both fluorinated and functionalized ambiphilic boronates is challenging and has received inadequate attention. Herein, we describe the -methyliminodiacetyl boronate [B(MIDA)]-directed halogenation of alkenes a complementary sequence involving fluoroalkyl radical addition followed by guided radical-to-metal oxidative addition and C-X reductive elimination. The alkali cation and functional groups in B(MIDA) enable coulombic interaction and weak attraction with halogens, which could weaken the Pd-X bond and assist in C-X bond formation and is verified by DFT calculations.

Chaperone-mediated autophagy (CMA) is a selective autophagic pathway responsible for degrading cytoplasmic proteins within lysosomes. Monitoring CMA flux is essential for understanding its functions and molecular mechanisms but remains technically complex and challenging. In this study, we developed a pH-resistant probe, KFERQ-Gamillus, by screening various green fluorescent proteins.

Background: Caustic substances can inflict severe damage on tissues upon contact. Knowledge about skin damage caused by sodium hypochlorite is quite limited, with only a few reports available in the literature.
Case Report: A 79-year-old female with severe cognitive decline presented with multiple skin ulcerations that were covered by a blackish-greyish eschar and surrounded by a purple erythematous halo.

Antipsychotic medications are used to treat a psychological condition called 'Schizophrenia'. However, its long-term administration causes irregular involuntary motor movements, targeting the orofacial regions. Glycyrrhizic acid (GA) is a naturally occurring triterpene saponin glycoside obtained from the roots of the Glycyrrhiza glabra (liquorice) plant and well known for its antioxidant, antiapoptotic and neuroprotective abilities.
