Retrieval of patent ductus arteriosus device embolization using hybrid approach: a case report.

Background: Patent ductus arteriosus (PDA) is a congenital heart defect that requires closure to prevent complications like heart failure and pulmonary hypertension. Catheter-based closure using devices such as the Amplatzer duct occluder is the preferred method due to its minimally invasive nature. However, device embolization is a rare but recognized complication, particularly in small children or high-flow PDAs.

Giant right and left atrium: spectrum of rheumatic triple valve disease (double hit with double impact): a case report and review of the literature.

Background: Rheumatic heart disease (RHD) continues to pose a significant burden on global health, particularly in socioeconomically disadvantaged populations. We present the case of a 38-year-old woman with severe multivalvular RHD and giant atria, highlighting the challenges and complexities of managing this condition.

Case Presentation: The patient presented with progressively worsening dyspnoea, signs of right heart failure, and severe valvular abnormalities.

Copper-catalyzed -thiocyanation of aromatic amines.

A copper-catalyzed direct -Csp-H thiocyanation of free anilines has been developed. This method employs stable and non-toxic ammonium thiocyanate as a thiocyanation source, and -butyl hydroperoxide as the oxidant, enabling the synthesis of -thiocyanated anilines with good yields and broad substrate tolerance. Hitherto, no reports have been found in the literature for the -thiocyanation of aromatic amines, making this reaction an important breakthrough in synthetic organic chemistry.

Comparison of dosimetric analysis of organs at risk and target volumes for ovoids and cylinders in endometrial carcinoma.

Purpose: To compare dose volume parameters of target and organs at risk in vaginal vault brachytherapy using ovoids or cylinder in post-operative endometrial carcinoma.

Material And Methods: The study was done among 25 histologically proven post-operative endometrial carcinoma patients requiring vaginal brachytherapy. All patients underwent both cylinder and ovoids application alternatively on weekly basis.

The Recent Advances in Iron-Catalyzed C(sp )-H Functionalization.

The use of iron as a core metal in catalysis has become a research topic of interest over the last few decades. The reasons are clear. Iron is the most abundant transition metal on Earth's crust and it is widely distributed across the world.
