Atypical hemolytic uremic syndrome (aHUS) is a rare complement-mediated disease that manifests as the triad of thrombotic microangiopathy. We identified two aHUS patients with neither anti-complement factor H (CFH) antibodies nor causative variants of seven aHUS-related genes (CFH, CFI, CFB, C3, MCP, THBD, and DGKE); however, their plasma showed increased levels of hemolysis by hemolytic assay, which strongly suggests CFH-related abnormalities. Using a copy number variation (CNV) analysis of the CFH/CFHR gene cluster, we identified CFH-CFHR1 hybrid genes in these patients. We verified the absence of aHUS-related abnormal CNVs of the CFH gene in control genomes of 2036 individuals in the general population, which suggests that pathogenicity is related to these hybrid genes. Our study emphasizes that, for patients suspected of having aHUS, it is important to perform an integrated analysis based on a clinical examination, functional analysis, and detailed genetic investigation.

The family , encompassing the genus and related taxa, comprises diverse Gram-negative, aerobic, rod-shaped bacteria found in varied habitats, including air, soil, water and glaciers. Recent genomic-based taxonomic revisions have reclassified some species into new genera, such as and , due to polyphyletic relationships within the family . Certain species are known for forming biofilms or functioning as aerobic anoxygenic phototrophic bacteria, traits that enhance resilience in extreme environments like the cryosphere.

Unlabelled: Fungal degradation of cellulose facilitates the sustainable harnessing of biosphere energy and carbon cycling. is one of the basidiomycetes with the largest number of hydrolytic enzymes in its genome. The mycelium of degrades cellulose through the production of substantial amounts of cellulase, enabling the absorption of carbon sources and nutrients essential for fruiting body development.

Asthma is a chronic inflammatory respiratory disease influenced by genetic and environmental factors. Emerging evidence suggests that microplastics and nanoplastics (NPs) pose significant health risks. When inhaled, these tiny particles can accumulate in the lungs, triggering inflammation, oxidative stress, and other disruptions in pulmonary function.

Musculoskeletal disorders, including bone fractures, osteoarthritis, and muscle injuries, represent a leading cause of global disability, revealing the urgency for advanced therapeutic solutions. However, current therapies face limitations including donor-site morbidity, immune rejection, and inadequate mimicry of dynamic tissue repair processes. DNA-based hydrogels emerge as transformative platforms for musculoskeletal reconstruction, with their sequence programmability, dynamic adaptability, and biocompatibility to balance structural support and biological functions.

Many species from the genus are causative agents of the bacterial zoonosis brucellosis. Until recently, it was generally believed that these bacteria exhibit strict host specificity; however, recent findings suggest otherwise. is an atypical species, no threat to humans, with a broad host spectrum, primarily found in wildlife and rodents, and is the only species isolated from soil, aquatic environments, and frogs, suggesting its environmental persistence and adaptability to diverse ecological niches.
