Background: Transthyretin amyloid cardiomyopathy (ATTR-CM) commonly leads to heart failure but has traditionally been an exclusion criterion in randomized clinical trials (RCTs) of sodium-glucose cotransporter 2 inhibitors (SGLT2i); therefore, the effects of these drugs in this population remain undocumented. In light of recent studies, this meta-analysis aimed to investigate the effect of SGLT2i on the prognosis of patients with ATTR-CM.

Methods: A comprehensive search of Medline, Scopus, and the Cochrane Library was conducted up to November 17, 2024.

Department of Chemical and P. Engineering, Research and Innovation Centre on CO2 and H2 (RICH), Khalifa University, Abu Dhabi, United Arab Emirates.

A comprehensive optimization of known prokaryotic autotrophic carbon dioxide (CO) fixation pathways is presented that evaluates all their possible variants under different environmental conditions. This was achieved through a computational methodology recently developed that considers the trade-offs between energy efficiency (yield) and growth rate, allowing us to evaluate candidate metabolic modifications for microbial conversions. The results revealed the superior configurations in terms of both yield (efficiency) and rate (driving force).

This paper explores the electrical conductivity interphase of Ag/Epoxy composite using modified McLachlan theory and 3D finite element composite model through experimental verification. The model characteristic presents conductivity as a dynamic function influenced by particle content, particle electrical properties, electrical properties transition, and an exponent. This model was meticulously crafted, considering the intricate interplay between the polymer matrix and silver particles, the tunnelling distance between adjacent silver particles, and the interphase regions around particles.

Research and Enterprise, University of Cyberjaya, Persiaran Bestari, Cyber 11, 63000, Cyberjaya, Selangor, Malaysia.

As a promising candidate for tackling drug-resistant cancers, triptolide, a diterpenoid derived from the Chinese medicinal plant Tripterygium wilfordii, has been developed. This review summarizes potential antitumor activities, including the suppression of RNA polymerase II, the suppression of heat shock proteins (HSP70 and HSP90), and the blockade of NF-kB signalling. Triptolide is the first known compound to target cancer cells specifically but spare normal cells, and it has success in treating cancers that are difficult to treat, including pancreatic, breast, and lung cancers.
