Effects of High-Intensity Interval Training and Continuous Training on Exercise Capacity, Heart Rate Variability and Isolated Hearts in Diabetic Rats.

Background: High-intensity interval training (HIIT) has been suggested as an alternative for continuous training (CT) in people with diabetes mellitus (DM) due to its short duration and potential to improve adherence to exercise. However, data on its impact on heart rate variability (HRV) are scarce.

Objectives: To assess and compare the effects of HIIT and CT on exercise capacity, HRV and isolated hearts in diabetic rats.

Functional Effects of Hyperthyroidism on Cardiac Papillary Muscle in Rats.

Background: Hyperthyroidism is currently recognized to affect the cardiovascular system, leading to a series of molecular and functional changes. However, little is known about the functional influence of hyperthyroidism in the regulation of cytoplasmic calcium and on the sodium/calcium exchanger (NCX) in the cardiac muscle.

Objectives: To evaluate the functional changes in papillary muscles isolated from animals with induced hyperthyroidism.

[Reference curves for assessing the physical growth of male Wistar rats].

Introduction: Wistar rats are one of the most popular strains routinely used for research in the laboratory to serve as an important research tool, so it requires strict control of variables such as age, sex and body weight, and Thus to extrapolate the results to the human model.

Objective: To develop reference curves for assessing the physical growth of male Wistar rats according to chronological age and somatic maturation from a non-invasive.

Methodology: The subjects studied were 731 male Wistar rats transversely.

Ethyl 2-cyanoacrylate tissue adhesive in partial lobectomy in rats.

Objective: To determine the efficacy of ethyl 2-cyanoacrylate adhesive in repairing the lung parenchyma after partial lobectomy in rats, in terms of hemostasis/aerostasis, scarring, and surgical time.

Methods: The study involved 30 Wistar rats, randomly divided into five groups (one control group and four study groups). In the study groups, the lung parenchyma was repaired with either cyanoacrylate adhesive or surgical suture following resection of a small or large fragment (25% or 50%, respectively) of the left caudal lung lobe.
