Sarcoptic mange, a disease caused by the burrowing mite Sarcoptes scabiei, is globally endemic and an emerging threat to wildlife. Although many studies have shown that wildlife diseases play key roles in biodiversity conservation, knowledge about sarcoptic mange is still insufficient. In this study, we aim to improve the understanding of the impacts of sarcoptic mange on wildlife populations, the mechanisms involved in its eco-epidemiology and the associated risks to public and ecosystem health by investigating mass death events in gorals and serows in the Qinling Mountains.

Here, we apply density functional theory to study the photophysical properties of a series of square planar Pt(ii) complexes in both monomeric and dimeric forms. We reveal that four monomeric Pt(ii) complexes are dominated by triplet ligand-to-ligand charge-transfer, and the lack of the triplet metal-to-ligand charge-transfer feature results in weak spin-orbit coupling (SOC), which leads to limited radiative rates; moreover, calculated nonradiative transition rates are one or two orders of magnitude higher than those radiative rates because a large amount of reorganization energy caused by the vibration of the bipyrazolate (bipz) ligand cannot be readily suppressed in the monomeric form.

Patient Concerns: We report a patient, who was admitted to our hospital for colonoscopy.
Diagnoses: Under a microscope, all the segments of the whole colon and the varicose veins showed multiple flaky spider-like telangiectasia changes.
Colon cancer is one of the most fatal cancers in the United States, and is characterized by the presence of chromosomal instability (CIN), causes of which are largely unclear. Emerging evidence indicates that abnormal spindle geometry and supernumerary centrosomes lead to CIN in cells. However, if and how spindle geometry defects and centrosomes amplification occur in colon cancer remains unknown.

Objective: To investigate the effects of Danshen Injection (DSI) on the proliferation of rheumatoid arthritis fibroblast-like synoviocytes (RA FLSs) cultured in RA patients' serum.
Methods: The RA FLSs harvested from RA patients' synovial fluid were primarily cultured by routines. The cells were cultured with 10% inactivated human serum (the healthy human serum and the RA patients' serum) for 24 h.
Med19 was a member of the Mediator complex which forms the bridge between transcriptional activators and RNA polymerase II. We aim to investigate the functional role of Med19 in the progression of human gastric carcinoma. The correlation between Med19 expression and clinicopathologic features in 60 gastric carcinoma specimens was analyzed by using immunohistochemistry.
