Article Synopsis
- A new bacterial phylum has been identified from hot spring metagenomes and public genomic data, falling under a specific superphylum.
- The phylum includes one class and five orders, primarily consisting of facultative anaerobes.
- One of its orders uses hydrogen for carbon fixation via the Calvin Benson Bassham cycle, highlighting its importance in the carbon cycle and its evolution influenced by horizontal gene transfer.
Candidate bacterial phylum CSP1-3 has not been cultivated and is poorly understood. Here, we analyzed 112 CSP1-3 metagenome-assembled genomes and showed they are likely facultative anaerobes, with 3 of 5 families encoding autotrophy through the reductive glycine pathway (RGP), Wood-Ljungdahl pathway (WLP) or Calvin-Benson-Bassham (CBB), with hydrogen or sulfide as electron donors. Chemoautotrophic enrichments from hot spring sediments and fluorescence hybridization revealed enrichment of six CSP1-3 genera, and both transcribed genes and DNA-stable isotope probing were consistent with proposed chemoautotrophic metabolisms.

- The study analyzes clinical features in juvenile systemic lupus erythematosus (J-SLE) to better classify its patient subgroups through cluster analysis.
- A total of 404 patients were examined, leading to the identification of four distinct clinical phenotypes, each exhibiting different symptoms and disease severities.
- The findings suggest a need for tailored therapies, highlighting the importance of including low-dose aspirin in treatment plans, while further research is necessary to confirm these phenotype patterns.
Objective: To assess the changes in blood vessel stiffness and digital pulse wave amplitude because of flowmediated dilatation, and to explore how these two variables change when endothelial dysfunction is experimentally induced.
Methods: The experimental study was conducted at the departments of physiology at the College of Medicine, Mustansiriyah University, and the College of Medicine, Al-Iraqia University, Baghdad, Iraq, from October 14, 2021, to May 31, 2022, and comprised healthy young males who were subjected to the flow-mediated dilatation technique on the left brachial artery. Pulse transit time and the amplitude of the digital pulse wave were measured during reactive hyperaemia for 2.
The development of innovative methods for concealing critical data in multimedia files has exploded in information security in recent years. Cryptography and steganography cannot be used alone to protect data; rather, they can be combined and used in a single system. Audio steganography is among the most important information security techniques.
