Temperature, as a powerful variable in conventional LC is discussed from a fundamental point of view and illustrated with applications from the author's laboratory. Emphasis is given to the influence of temperature on speed, selectivity, efficiency, detectability, and mobile phase composition (green chromatography). The problems accompanying the use of elevated temperature and temperature programming in LC are reviewed and solutions are described. The available stationary phases for high temperature operation are summarized and a brief overview of recent applications reported in the literature is given.

African swine fever (ASF) has widely spread around the world in the last 100 years since its discovery. The African swine fever virus (ASFV) particles are made of more than 150 proteins, with the p17 protein encoded by the D117L gene serving as one of the major capsid proteins and playing a crucial role in the virus's morphogenesis and immune evasion. Thus, monoclonal antibody (mAb) targeting p17 is important for the research and detection of ASFV infection.

Purpose: To evaluate the effectiveness and safety of an upgraded integrated vacuum suction catheter in semi-rigid ureteroscopic laser lithotripsy (VC-URSL) compared to traditional methods for treating impacted upper ureteral stones.
Patients And Methods: This prospective, randomized controlled trial was conducted from September 2022 to March 2024 at a single center, enrolling 95 patients aged 18 to 70 years with a single radiopaque impacted upper ureteral stone. Participants were randomized into two groups: the VC-URSL group used an integrated vacuum suction catheter featuring a stainless steel stabilizing tube and a narrowed distal end to prevent obstruction, while the T-URSL group underwent standard ureteroscopic lithotripsy without vacuum assistance.

Purpose: Mucormycosis is a rare but emerging and life-threatening infection caused by environmental mold, with a mortality rate of 30-70% despite progress in management. A better understanding could improve its management.
Method: We conducted a single-center retrospective study of all cases of mucormycosis observed over a decade at the University Hospital of Caen.

Pertussis remains a significant public health concern despite effective vaccines due to diagnostic challenges and symptom overlap with other respiratory infections. This study assesses the prevalence of using advanced polymerase chain reaction (PCR) testing and examines the clinical outcomes over a one-month follow-up. We conducted a cross-sectional study at the University Hospital of Larissa, Greece, from April to June 2024, collecting 532 nasopharyngeal swabs from patients with respiratory symptoms.

Porcine circovirus type 2 (PCV2) is an important swine pathogen that has caused considerable economic losses in the global swine industry. During our surveillance of pigs in Shandong, China, from 2018 to 2020, we found that the PCV2 infection rate was 7.89% (86/1090).
