The methanol extract of the whole plant of Vernonia cinerea (MEVC) was evaluated for its antipyretic potential on normal body temperature and yeast-induced pyrexia in rats. MEVC significantly reduced the normal body temperature at doses of 250 and 500 mg/kg body weight p.o. MEVC also lowered the elevated body temperature in the case of yeast-induced pyrexia in a dose dependent manner. The antipyretic effect of the extract at a dose of 500 mg/kg was identical to that of the standard drug paracetamol.

Juvenile Chinook Salmon (Oncorhynchus tshawytscha) populations have decreased substantially in the Sacramento-San Joaquin Delta (Delta) over the past decades, so considerably that two of the four genetically distinct runs are now listed in the Endangered Species Act. One factor responsible for this decline is the presence of contaminants in the Delta. Insecticides, used globally in agricultural, industrial, and household settings, have the potential to contaminate nearby aquatic systems through spray drift, runoff, and direct wastewater discharge.

Background: Intrahepatic and extrahepatic bile duct stones (BDSs) have a high rate of residual stones, a high risk of recurrence, and a high rate of reoperation. It is very important to take timely and effective surgical intervention for patients.
Aim: To analyze the efficacy, postoperative rehabilitation, and quality of life (QoL) of patients with intra- and extrahepatic BDSs treated with endoscopic retrograde cholangiopancreatography (ERCP) + endoscopic papillary balloon dilation (EPBD) + laparoscopic hepatectomy (LH).

Objectives: To evaluate the therapeutic effect of suraxavir marboxil (GP681, abbreviated as suraxavir) in adults with uncomplicated influenza.
Methods: We conducted a multi-center randomized, double-blind, placebo-controlled phase 2 trial in 18 Chinese centers. Participants had to be aged 18-65 years with positive influenza test, presenting with at least one influenza systemic and respiratory symptoms in at least moderate severity within 48 hours of onset.

This study investigated the single and combined effects of environmental heat stress and physical exercise on executive function (EF) performance, prefrontal cortex oxygenation, thermoregulatory responses and subjective perceptions. Sixteen subjects participated in four experimental sessions: two under moderate environmental conditions (23 °C), with and without physical exercise (R23, E23), and two under hot environmental conditions (35 °C), with and without physical exercise (R35, E35). In each session, participants completed EF tasks before and after 1 h of passive rest or 45 min of moderate-intensity cycling followed by 15 min of rest.
