Tailoring catalysis at the atomic level: trends and breakthroughs in single atom catalysts for organic transformation reactions.

The utilization of precise materials in heterogeneous catalysis will provide various new possibilities for developing superior catalysts to tackle worldwide energy and environmental issues. In recent years, single atom catalysts (SACs) with excellent atom utilization and isolated active sites have progressed dramatically as a thriving sector of catalysis research. Additionally, SACs bridge the gap between homogeneous and heterogeneous catalysts and overcome the limitations of both categories.

Venous Thromboembolism (VTE) Prophylaxis After Abdominoplasty and Liposuction: A Review of the Literature.

Background: The aim of this review article was to study recent articles and summarise the guidelines, indications, risks and benefits of using VTE prophylaxis in patients undergoing abdominoplasty and liposuction.

Methods: A search of PubMed was performed using selected keywords related to the topic. Based on the inclusion and exclusion criteria, a total of 25 articles were included in the review.

Association between gamma glutamyl transferase and insulin resistance markers in healthy obese children.

Objective: To study the relationship of gamma glutamyl transferase (GGT) with insulin resistance markers [fasting insulin and Homeostasis Model Assessment of-insulin resistance (HOMA-IR)] and to assess the role of GGT as a determinant of insulin resistance in healthy obese children.

Material And Methods: Fifty healthy obese children (boys and girls with mean age 9.2 +/- 0.
