Diversity of the Obligate Gut Bacteria Indicates Host-Symbiont Coevolution at the Population Level in the Plataspid Stinkbug .

is an obligate gut bacterium in stinkbugs that belong to Plataspidae family (Hemiptera: Heteroptera). It is vertically transmitted to newborn nymphs through capsules laid on eggs by maternal stinkbugs. Previous research has established a pattern of strict cospeciation between Plataspidae stinkbugs and .

Precision and Robust Models on Healthcare Institution Federated Learning for Predicting HCC on Portal Venous CT Images.

Hepatocellular carcinoma (HCC), the most common type of liver cancer, poses significant challenges in detection and diagnosis. Medical imaging, especially computed tomography (CT), is pivotal in non-invasively identifying this disease, requiring substantial expertise for interpretation. This research introduces an innovative strategy that integrates two-dimensional (2D) and three-dimensional (3D) deep learning models within a federated learning (FL) framework for precise segmentation of liver and tumor regions in medical images.

Design, synthesis, and evaluation of VHL-based EZH2 degraders for breast cancer.

EZH2 (enhancer of zeste homolog 2) is one of the most important histone methyltransferases (HMTs), and overexpression of EZH2 can lead to proliferation, migration and angiogenesis of tumor cells. But most of EZH2 inhibitors are only effective against some hematologic malignancies and have poor efficacy against solid tumors. Here, we report the design, synthesis, and evaluation of highly potent proteolysis targeting chimeric (PROTACs) small molecules targeting EZH2.

Design, synthesis and biological evaluation of pyrimidine base hydroxamic acid derivatives as dual JMJD3 and HDAC inhibitors.

The Jumonji domain-containing protein demethylase 3 (JMJD3) and histone deacetylase (HADC) are related to various cancers and regard as antitumor targets for drug discovery. In this study, based on rational drug design strategy, we designed and synthesized a series of pyrimidine derivatives with hydroxamic acid as novel dual JMJD3 and HDAC inhibitors for synergistic cancer treatment. Compound A5b exhibited inhibitory potency against JMJD3 and HDAC1/6 simultaneously and favorable cytotoxicity against human cancer cells such as A549 and U937.

Decontamination of mustard sulfur and VX by sodium percarbonate complexed with 1-acetylguanidine as a novel activator.

The peroxide-based decontaminants had attracted great attention for degradation of chemical warfare agents (CWAs) because of their high performance, non-corrosive and environmental-friendly merits. Hydrogen peroxide can be activated by some organic activators to enhance the oxidation ability. In this work, a novel formula based on sodium percarbonate (SPC) complexed with 1-acetylguanidine (ACG) was investigated for decontamination of sulfur mustard (HD) and VX as CWAs.

Discovery of triazolo [1,5-a] pyridine derivatives as novel JAK1/2 inhibitors.

Small molecule JAK inhibitors have been demonstrated efficacy in rheumatoid arthritis, inflammatory bowel disease, and psoriasis with the approval of several drugs. Aiming to develop potent JAK1/2 inhibitors, two series of triazolo [1,5-a] pyridine derivatives were designed and synthesized by various strategies. The pharmacological results identified the optimized compounds J-4 and J-6, which exerted high potency against JAK1/2, and selectivity over JAK3 in enzyme assays.

Identification of new defective interfering RNA species associated with porcine reproductive and respiratory syndrome virus infection.

In the present study, seven new defective interfering (DI) RNA species of porcine reproductive and respiratory syndrome virus (PRRSV) were identified. RT-PCR, Northern blot and sequence analyses indicated that these DI RNA specie have deletions of 8513-9176 nucleotides located between Nsp1/Nsp2 and Nsp10. Compared with the previous DI RNAs of PRRSV reported, they have three distinct characteristics: much smaller deletion sizes; different nucleotide repeats (2-12nt) used in the junction sites and in-frame deletions.

Successful medical treatment of spinal epidural abscess.

Spinal epidural abscess is a rare but potentially fatal disease. A 67-year-old female suffered fever and painful swelling of the right knee and lower leg for one week. Both synovial fluid and blood cultures yielded methicillin-sensitive Staphylococcus aureus.
