Article Synopsis
- The review analyzes how different infections in pregnant women affect their health, the baby’s development, and the placenta.
- It discusses various types of infections (bacterial, viral, parasitic), their transmission, symptoms, and how they can be identified through placental examination.
- The importance of early diagnosis and treatment is highlighted, as many infections can show no symptoms, and the placenta's role in protecting against these infections is also explored.
In vivo retrievals of metallic orthopedic implants have shown selective dissolution of Ti-6Al-4V, where the vanadium-rich β phase preferentially corrodes from the surface. This damage, typically observed in crevices, is not directly caused by wear mechanics and the underlying electrochemical mechanism remains poorly understood. Previous studies show that fretting corrosion can cause negative potential drops, resulting in a decrease in surface oxide passivation resistance and the electrochemical generation of reactive oxygen species (ROS) at metallic surfaces.

CoCrMo mechanical properties and corrosion resistance are vital to the structural integrity of implants and dental appliances. The goal of this work is to assess the resistivity of AM cobalt chromium alloys by comparing them with traditional CoCrMo, regarding electrochemical properties resulting from microstructural and oxide film differences.
View Article and Find Full Text PDFAg and Au nanoparticles (NPs) were used as color indicators to determine the monomer/micelle adsorption on the NP surface. A simple methodology based on the color change of Ag/Au NPs upon interacting with surface-active molecules was developed. A contrasting color change occurred when NPs interact with the monomer/micelle.

Materials And Methods: A sub-analysis was performed using data from the LIBERTY trial (.gov identifier NCT01855412), a prospective, observational, core-laboratory adjudicated, multicenter study of endovascular intervention in 1204 patients.
