Unusual direct immunofluorescence (DIF) pattern in pemphigus herpetiformis- A case report.

Pemphigus herpetiformis (PH) is an autoimmune intraepithelial bullous skin disorder. A 61-year-old female presented with history of multiple pruritic erosions, ulcers all over body, and diffuse loss of hair over scalp. Oral and genital mucosas were uninvolved.

Comparative evaluation of antimicrobial efficacy of glass ionomer cement added with propolis, chitosan, and chlorhexidine against and : An study.

Context: Glass ionomer cement (GIC) is known for its antimicrobial activity due to its low pH and fluoride release. The fluoride released has an inhibitory effect on a finite number of bacteria which leads to the risk of recurrent caries. Additives such as chlorhexidine (CHX) and triclosan have been tried to maximize the antibacterial activity of GIC.

Synthesis and characterization of silica@copper core-shell nanoparticles: application for conjugate addition reactions.

Silica@copper (SiO2@Cu) core-shell nanoparticles were synthesized and well characterized by XRD, TEM, AFM, XPS, UV/Vis, TGA-MS, and ICP-AES techniques. The synthesized SiO2@Cu core-shell nanoparticles were employed as catalysts for the conjugate addition of amines to alpha,beta-unsaturated compounds in water to obtain beta-amino carbonyl compounds in excellent yields in shorter reaction times. Furthermore, the catalyst works well for hetero-Michael addition reactions of heteroatom nucleophiles such as thiols to alpha,beta-unsaturated compounds.
