Copper(i) as a reducing agent for the synthesis of bimetallic PtCu catalytic nanoparticles.

This work investigates the potential utilization of Cu(i) as a reducing agent for the transformation of the platinum salt KPtCl, resulting in the production of stable nanoparticles. The synthesized nanoparticles exhibit a bimetallic composition, incorporating copper within their final structure. This approach offers a convenient and accessible methodology for the production of bimetallic nanostructures.

Umbilical cord cyst presenting as an omphalocele at 15 weeks' gestation. A case report.

A small, cystic structure was identified on a routine ultrasound scan performed for dating at 15 weeks' gestation. Originally it was thought to be an omphalocele, but further examination confirmed its origin in the cord several centimeters distal to the fetus. Close scrutiny of ultrasonograms is important since technical capabilities permit high-resolution scans during early gestation.

Antenatal diagnosis of epignathus with neonatal survival. A case report.

Antenatal diagnosis was made of bilobed epignathus arising from the fetal palate. The fetus survived. Antenatal recognition of this malformation allows adequate preparation of the neonatal and surgical teams to ensure optimal fetal survival.

Late disappearance of fetal choroid plexus cyst: case report and review of the literature.

Ultrasound diagnosis of a lateral ventricle choroid plexus cyst was made in a 20-week gestational age fetus. The cyst remained visible until the 34th week, after which it spontaneously resolved. Persistence of such cysts beyond 23 weeks has been suggested as a poor prognostic sign by some investigators.
