Chromosome-level genome assembly of a specialist walnut pest Atrijuglans aristata.

Gelechioidea represents the most diverse superfamily of tiny boring pests in Lepidoptera that pose a serious threat to agricultural and forestry economic crops. However, the lack of high-quality genome of highly specialized species makes it difficult to draw general conclusions about the mechanism of the close binding relationship between pests and crops. In this study, based on second- and third-generation sequencing reads, we constructed a chromosome-level genome for the Atrijuglans aristata, a specialized boring pest, that specifically harms the green husk of cultivated walnuts.

Spatial immune scoring system predicts hepatocellular carcinoma recurrence.

Given the high recurrence rates of hepatocellular carcinoma (HCC) post-resection, improved early identification of patients at high risk for post-resection recurrence would help to improve patient outcomes and prioritize healthcare resources. Here we observed a spatial and HCC recurrence-associated distribution of natural killer (NK) cells in the invasive front and tumour centre from 61 patients. Using extreme gradient boosting and inverse-variance weighting, we developed the tumour immune microenvironment spatial (TIMES) score based on the spatial expression patterns of five biomarkers (SPON2, ZFP36L2, ZFP36, VIM and HLA-DRB1) to predict HCC recurrence risk.

[Research progress on the role of mitochondrial complex I in the pathogenesis of Parkinson's disease].

Currently, the incidence of Parkinson's disease (PD) is on the rise. More and more evidences suggest that mitochondrial dysfunction plays a crucial role in the etiology of PD, and dysfunction of mitochondrial complex I (MCI) is one of the most critical factors leading to mitochondrial dysfunction. On one hand, MCI dysfunction stimulates dopaminergic neurons to produce reactive oxygen species (ROS).

Screening the human druggable genome identifies ABHD17B as an anti-fibrotic target in hepatic stellate cells.

Hepatic stellate cells (HSCs) are activated with chronic liver injury and transdifferentiate into myofibroblasts, which produce excessive extracellular matrices that form the fibrotic scar. While the progression of fibrosis is understood to be the cause of end-stage liver disease, there are no approved therapies directed at interfering with the activity of HSC myofibroblasts. Here, we perform a high-throughput small interfering RNA (siRNA) screen in primary human HSC myofibroblasts to identify gene products necessary for the fibrotic phenotype of HSCs.

In Vivo Quantification of Anterior and Posterior Chamber Volumes in Mice: Implications for Aqueous Humor Dynamics.

Purpose: Aqueous humor inflow rate, a key parameter influencing aqueous humor dynamics, is typically measured by fluorophotometry. Analyzing fluorophotometric data depends, inter alia, on the volume of aqueous humor in the anterior chamber but not the posterior chamber. Previous fluorophotometric studies of the aqueous inflow rate in mice have assumed the ratio of anterior:posterior volumes in mice to be similar to those in humans.
