Alteration of Immune Function and Gut Microbiome Composition in Carassius auratus Challenged With Rahnella aquatilis.

Rahnella aquatilis as an emerging pathogen can cause bacterial enteritis in cyprinid fish such as crucian carp Carassius auratus. Currently, the characterisation of immune function and gut microbiome composition in C. auratus orally challenged by R.

Transition of iPB-1 with low molecular weight crystallized from solutions.

The dimension or entanglement of polymer chains is crucial to chain dynamics, and the polymer chains can be diluted and disentangled in a solution by reducing the interaction with each other. This letter addresses the role of solution concentration in the crystal transition of isotactic polybutene-1 (iPB-1) with low molecular weight crystallized from solution. It turned out that the transition of iPB-1 obtained from the higher concentration of the solution is faster than that obtained from the lower one.

Form II to form I transition in solution-crystallized isotactic polybutene-1.

Different polymer chains in a solution or melt have different conformations with corresponding entropy at each moment, which would be confined after crystallization. Equilibrium concept-based conformation or conformational entropy depends on chain dynamics, which is related to the effect of energy on conformational changes in polymer chains. Herein, an isotactic polybutene-1 (iPB-1) crystal was crystallized from solution by adding a precipitant at various temperatures.

Multi-omics analysis of miRNA-mediated intestinal microflora changes in crucian carp infected with .

Infection by an emerging bacterial pathogen caused enteritis and septicemia in fish. However, the molecular pathogenesis of enteritis induced by infection and its interacting mechanism of the intestinal microflora associated with microRNA (miRNA) immune regulation in crucian carp are still unclear. In this study, intraperitoneally injected with KCL-5 was used as an experimental animal model, and the intestinal pathological changes, microflora, and differentially expressed miRNAs (DEMs) were investigated by multi-omics analysis.

Artificial light affects foraging behavior of a synanthropic bat.

Artificial light at night has been considered an emerging threat to global biodiversity. However, the impacts of artificial light on foraging behavior in most wild animals remain largely unclear. Here, we aimed to assess whether artificial light affects foraging behavior in Asian parti-colored bats (Vespertilio sinensis).

Applying T-classifier, binary classifiers, upon high-throughput TCR sequencing output to identify cytomegalovirus exposure history.

With the continuous development of information technology and the running speed of computers, the development of informatization has led to the generation of increasingly more medical data. Solving unmet needs such as employing the constantly developing artificial intelligence technology to medical data and providing support for the medical industry is a hot research topic. Cytomegalovirus (CMV) is a kind of virus that exists widely in nature with strict species specificity, and the infection rate among Chinese adults is more than 95%.

Multiomics analysis revealed miRNAs as potential regulators of the immune response in gills to infection.

The gill of fish is an important immune organ for pathogen defense, but its microRNA (miRNA) expression and regulatory mechanism remain unclear. In this study, we report on the histopathological and immunohistochemical features of the gills of the crucian carp challenged with . Small RNA libraries of the gills were constructed and sequenced on the Illumina HiSeq 2000 platform.

Hyper-excitability of corticothalamic PT neurons in mPFC promotes irritability in the mouse model of Alzheimer's disease.

Neuropsychiatric symptoms in patients with Alzheimer's disease (AD) are presented as early as the mild cognitive impairment (MCI) stage. However, it remains unclear whether separate neuronal populations encode distinct aspects of the neuropsychiatric symptoms and drive them differently. Here, we report that pyramidal tract (PT) neurons projecting to the thalamus, but not to the pons or medulla, in the medial prefrontal cortex (mPFC) of the mouse model of AD show increased excitability, which is associated with increased irritability and aggressivity.
