Dihydropyrimidine enzyme activity and its effect on chemotherapy toxicity: importance of genetic testing.

Purpose: Patients with partial or complete DPD deficiency have decreased capacity to degrade fluorouracil and are at risk of developing toxicity, which can be even life-threatening.

Case: A 43-year-old man with moderately differentiated rectal adenocarcinoma on capecitabine presented to the emergency department with complaints of nausea, vomiting, diarrhea, weakness, and lower abdominal pain for several days. Laboratory findings include grade 4 neutropenia (ANC 10) and thrombocytopenia (platelets 36,000).

Histone deacetylase 6 inhibition prevents hypercholesterolemia-induced erectile dysfunction independent of changes in markers of autophagy.

Background: Erectile dysfunction is a condition with a rapidly increasing prevalence globally with a strong correlation to the increase in obesity and cardiovascular disease rates.

Aim: The aim of the current study is to investigate the potential role of tubacin, a histone deacetylase 6 (HDAC6) inhibitor, in restoring erectile function in a hypercholesterolemia-induced endothelial dysfunction model.

Methods: Thirty-nine male C57Bl/6 J mice were divided into 3 groups.

Tracking the Ghosts of the Himalayas: Snow Leopard Conservation Insights From Satellite Collar Data.

This study presents the first movement analysis of snow leopards () using satellite telemetry data, focusing on the northeastern Himalayas of Nepal. By examining GPS-based satellite collar data between 2013 and 2017 from five collared snow leopards (effectively three individuals), the research uncovered distinct movement patterns, activity budgeting and home range utilisation from one adult male and two sub adult females. Hidden Markov models (HMMs) revealed three behavioural states based on the movement patterns-slow (indicative of resting), moderate and fast (associated with travelling) and demonstrated that the time of day influenced their behavioural state.

Small Molecule with Big Impact: Metarrestin Targets the Perinucleolar Compartment in Cancer Metastasis.

Metarrestin (ML246) is a first-in-class pyrrole-pyrimidine-derived small molecule that selectively targets the perinucleolar compartment (PNC). PNC is a distinct subnuclear structure predominantly found in solid tumor cells. The occurrence of PNC demonstrates a positive correlation with malignancy, serving as an indicator of tumor aggressiveness, progression, and metastasis.

Robot Assisted Cholecystectomy Using the BORNS Simphoni System.

Background And Objective: Robotic cholecystectomy has technical advantages of 3D visualization, enhanced instrument maneuverability, and increased precision. Less chance of conversion to open and biliary spillage. This study explores the utilization of the BORNS Simphoni Robotic System for robotic cholecystectomy.
