Article Synopsis
- The study investigates if baseball pitchers have enough elbow varus strength to relieve stress on the ulnar collateral ligament (UCL) during pitching, focusing on how valgus loads affect the medial elbow compartment.
- Researchers measured the peak elbow varus moment during different pitch types (fastball, slider, curveball, and changeup) in 14 professional and 8 collegiate pitchers using an electromagnetic tracking device and an isokinetic dynamometer.
- Results showed that many pitchers did not possess sufficient varus strength to fully unload the UCL during certain pitch types, indicating that while muscular support can help, valgus loading on the UCL appears to be an inherent challenge in baseball pitching.
The present work investigates the long-term effects of continuous low dose-rate (20 mGy/day to total doses of 1-8 Gy) gamma-ray exposure on the hematopoietic cells of specific pathogen-free C3H/HeN mice. Peripheral white blood cell (WBC) counts decreased on days 206, 471, and 486, with no significant changes in red blood cell (RBC) and platelet (PLT) counts. The number of colony forming units (CFU-S and CFU-GM) in the bone marrow and spleen from irradiated mice decreased with increasing total dose on day-12 and day-7.

EHV-1 also causes lethal encephalitis in small laboratory animals such as mice and hamsters experimentally. EHV-1 ORF76 is a homolog of HSV-1 US9, which is a herpesvirus kinase.

The two antennas have differing amounts of bacteriochlorophyll (BChl) ; however, their significance in spectral tuning remains elusive. Here, we report a high-precision evaluation of the physicochemical factors contributing to the variation in absorption maxima between LH1 and LH2, namely, BChl structural distortion, protein electrostatic interaction, excitonic coupling, and charge transfer (CT) effects, as derived from detailed spectral calculations using an extended version of the exciton model, in the model purple bacterium .

- - The study compared mitochondrial morphology and gene expression in liver samples from patients with biliary atresia (BA), infantile cholestasis (IC), and normal liver (NL) to determine their prognostic indicators.
- - Results showed that levels of heat shock protein 60 (HSP60) were significantly lower in BA and IC compared to NL, suggesting a correlation between HSP60 levels and liver health post-surgery (portoenterostomy).
- - Transmission electron microscopy revealed that BA patients had more mitochondrial abnormalities compared to IC and NL, indicating that mitochondrial dysfunction might contribute to the disease's severity and potential outcomes following treatment.
