Infective endocarditis is a serious heart disease that can affect native and prosthetic valves. Staphylococci and Streptococci are the etiological agents in almost 80% of cases. Human brucellosis is a multiple organ disease often transmitted via contaminated, unpasteurized goat milk and cheese. Brucella endocarditis is a rare complication associated with elevated morbidity and mortality rates; it can affect native or, even more rarely, prosthetic valves. In this report, we present the successful management of an infected aortic biological prosthesis in a man of 68 years.

While all native tRNAs undergo extensive post-transcriptional modifications as a mechanism to regulate gene expression, mapping these modifications remains challenging. The critical barrier is the difficulty of readthrough of modifications by reverse transcriptases (RTs). Here we use Induro-a new group-II intron-encoded RT-to map and quantify genome-wide tRNA modifications in Induro-tRNAseq.

Osteoarthritis affects approximately 500 million individuals globally, with severe cases often leading to osteochondral defects. Biomimetic collagen-hydroxyapatite scaffolds have been investigated for the treatment of osteochondral defects. However, achieving precise mimicry of the intricate composition, gradient nanostructure, and biological function of native tissue remains a formidable challenge.

Plant growth-promoting bacteria (PGPB) are considered an effective eco-friendly biostimulator. However, relatively few studies have examined how PGPB affect the native bacterial community of major crops. Thus, this study investigates the impact of a PGPB consortium, comprising Pseudomonas sp.

Bee population decline is associated with various stressors, including exposure to pollutants. Among these, titanium dioxide (TiO), an emerging nanoparticle (NP) pollutant, potentially affects living organisms, including bees. This study evaluates the impact of TiO NPs ingestion (1.

Due to its commercial availability and well-defined structure, the interaction between bovine protein β-lactoglobulin (βLG) and a wide variety of non-native ligands - including transition metal complexes - has been explored, but its application as an artificial metalloenzyme scaffold is limited. This protein is hypothesized to transport fatty acids and other nutrients during juvenile development, and it binds hydrophobic ligands inside a binding pocket constructed upon an 8-stranded β-barrel, called the 'calyx'. Herein, we compare the binding behavior of two rhenium(anthracene-bispyridine) ('Anth-py') tricarbonyl complexes, one with a 12‑carbon chain appended to the ligand scaffold ('Anth-py') to βLG.
