As a common disorder, acute kidney injury (AKI) is characterized by high mortality and morbidity, and current therapeutic options for AKI remain limited. Irisin, a muscle factor, plays an important role in metabolic disorders. However, the role of irisin in AKI is still unclear. To assess the effect of irisin on the course of AKI, we used an ischemia/reperfusion (I/R) C57BL/6 mouse model. Supplementation with irisin attenuated kidney injury induced by I/R, as shown by decreases in the levels of serum...

Complex transcatheter cardiac procedures, such as valve replacements, are often difficult to prepare for. Small anatomical differences can make big impacts on outcomes. Clinicians and researchers have been using models, both virtual and 3D printed, to improve procedural outcomes, design new devices, and to invent new therapeutic techniques. These models generally help professionals to understand nuances between patients, but they don’t reproduce the exact shapes and dynamics of moving tissues and...

Neuralink, one of Elon Musk’s newest ventures, was founded in 2016 but little has been known about the startup other than that it would somehow actualize Musk’s vision of a revolutionary implantable brain device. During a webcast last week, Musk and his team unveiled a bit more about what the company has been up to, including a live demo involving a trio of pigs. The Neuralink implant, known as the “Link,” is essentially a miniaturized version of a deep brain stimulator. It’s...

The majority of bacteria within the human body are lysogens, often harboring multiple bacteriophage sequences (prophages) within their genomes. While several different types of environmental stresses can trigger or induce prophages to enter into the lytic cycle, they have yet to be fully explored and understood in the human microbiota. In the laboratory, the most common induction method is the DNA damaging chemical Mitomycin C. Although pH has been listed in the literature as an induction method,...

Novel porcine circovirus type 3 (PCV3), first identified in the United States, has been detected in many other countries. Porcine circovirus is associated with postweaning multisystemic wasting syndrome, reproductive failure, congenital tremors, and other clinical symptoms. In this study, we established a double polymerase chain reaction assay for detecting both porcine circovirus type 2 (PCV2) and PCV3. This is the first study to detect and characterize the PCV3 genome in the Tianjin region of North...

Capuli (Prunus serotina subsp. capuli) is a tree species that is widely distributed in the northern Andes. In Prunus, fruit set and productivity appears to be limited by gametophytic self-incompatibility (GSI) which is controlled by the S-Locus. For the first time, this research reveals the molecular structure of the capuli S-RNase (a proxy for S-Locus diversity) and documents how S-Locus diversity influences GSI in the species. To this end, the capuli S-RNase gene was amplified and sequenced in...

Common or bread wheat (Triticum aestivum L.) is the most important cereal crop in the world, including Kazakhstan, where it is a major agricultural commodity. Fungal pathogens producing leaf, stem, and yellow (stripe) rusts of wheat may cause yield losses of up to 50–60%. One of the most effective methods for preventing these losses is to develop resistant cultivars with high yield potential. This goal can be achieved using complex breeding studies, including the identification of key genetic factors...

Many subclades within the large North American freshwater fish genus Etheostoma (Percidae) show brilliant male nuptial coloration during the spring spawning season. Traditionally, perceived differences in color were often used to diagnose closely related species. More recently, perceived differences in male nuptial color have prompted further investigation of potential biodiversity using genetic tools. However, cryptic diversity among Etheostoma darters renders male nuptial color as unreliable for...
