Objective: To assess the change in relation of the peak quadriceps electromyographic signal to the peak torque produced during a train of 5 isokinetic knee extensions (from 90 degrees below horizontal at a constant speed of 60 degrees/s) at baseline, and at 4 and 8 weeks of pulmonary rehabilitation.
Design: In this prospective observational study, isokinetic contractions were recorded during the extensions from the knee bent at 90 degrees to the horizontal plane against graded resistance. Peak quadriceps torque signal (Tq) and peak electromyographic signal (Eq) were recorded by dynamometry and surface electrodes placed at designated locations over the muscle group, respectively.
U.S. military veterans have been heavily impacted by the opioid overdose crisis, with drug overdose mortality rates increasing by 53% from 2010-2019.

There is a lack of information on this pathology in our country regarding the treatment and evolution of patients who suffer it. The aim of this study was to evaluate the perioperative and oncological results in patients with advanced epithelial ovarian tumor.

- Leiomyomas of the urinary bladder are rare tumors that can be treated using various surgical methods depending on their size and location.
- A case study involving a 45-year-old woman with a 40-mm submucosal leiomyoma illustrates the effectiveness of a novel transvesical laparoscopic approach for excision.
- The procedure had no complications, and the patient remained asymptomatic after 60 months, supporting the feasibility of this technique for trained surgeons.
Partial cytochrome b DNA sequences for 62 Triatoma infestans were analyzed to determine the degree of genetic variation present in populations of this insect in the northwest region of Chuquisaca, Bolivia. A total of seven haplotypes were detected in the localities sampled. The phylogenetic relationship and population genetic structure of the haplotypes found in this region, indicate that there is greater variation in this relatively small region of Bolivia than what has been previously reported by studies using the same gene fragment, for more distant geographic areas of this country.
