Surgical options for Evans-Jensen type IV intertrochanteric femur fractures in the elderly over 65: a comparison between total hip arthroplasty and proximal femoral nail antirotation.

Background: Currently, there is no clear standard for the surgical options for Evans-Jensen Type IV intertrochanteric femur fractures in elderly patients over 65 years old. This study aims to retrospectively analyze and compare the early postoperative limb function and quality of life of patients treated with total hip arthroplasty (THA) and proximal femoral nail antirotation (PFNA) for this type of fracture. We hypothesize that there is no significant difference in complications and postoperative recovery between the two surgical methods.

Artificial intelligence-driven identification and mechanistic exploration of synergistic anti-breast cancer compound combinations from L.- Hand.-Mazz. herb pair.

Introduction: The L. (PVL) and Hand.-Mazz.

Influences of the second motion probing gradient -value and T2 relaxation time on magnetic resonance diffusion-derived 'vessel density' (DDVD) calculation: the examples of liver, spleen, and liver simple cyst.

Background: Magnetic resonance (MR) diffusion-derived 'vessel density' (DDVD) is calculated according to: DDVD = Sb0/ROI - S/ROI, where S and S refer to the tissue signal when -value is 0 or 2 s/mm. S and ROI can also be approximated by other low -values diffusion-weighted imaging (DWI). This study investigates the influence of the second motion probing gradient -value and T2 on DDVD calculations of the liver, spleen, and liver simple cyst.

Unveiling the Intratumor Microbiome in Liver Cancer: Current Insights and Prospective Applications.

The role of the gut microbiome in the development and progression of liver cancer has long been recognized. However, the presence of microbes in tumors that were previously considered sterile has only recently been discovered. The intratumor microbiome in liver cancer likely originates from various sources, including the gut, hematogenous spread from other mucosal locations, adjacent non-cancerous tissues, and co-metastasis with the tumor cells.

Dynamic changes in the gastrointestinal microbial communities of Gangba sheep and analysis of their functions in plant biomass degradation at high altitude.

Background: While Gangba sheep being well known for their unique flavour and nutritional value, harsh environmental factors negatively affect their growth and development, leading to poor productivity. The gastrointestinal tract microbiota plays an important role in host nutrient absorption and metabolism. The identification of dynamic changes in the gastrointestinal microbial communities and their functions is an important step towards improving animal production performance and health.
