Simultaneous effects of high-speed circuit training (HSCT) and high-speed interval training (HSIT) on physical fitness and lung volumes of males after coronavirus disease.

Background: People who are quarantined after coronavirus disease experience immobility, obesity and changes in the cardiopulmonary system. We hypothesized that the concurrent use of high-speed circuit training (HSCT) and high-speed interval training (HSIT) can be used to improve physical fitness and respiratory functions.

Methodology: Physical education students (n = 65, 18-22 yrs.

Vitamin B supplementation improved memory impairment following nicotine withdrawal in adolescent male rats: The role of oxidative stress, inflammatory, BDNF, GFAP, and AChE activity.

The present study aimed to assess the potential effect of vitamin B (Vit B) on cognition impairment caused by nicotine (Nic) cessation in adolescent male rats. Adolescent male rats were categorized into two main groups as vehicle (normal saline, intraperitoneally), and Nic group in which received Nic (2 mg/kg) from 21 to 42 days of ages and then the Nic group were divided into three groups as withdrawal (the animals returned to regular diet without treatment), second and third groups received bupropion (20 mg/kg), and Vit B at three different doses including 0.5,1, and 1.

Physical exercise for a healthy pregnancy: the role of placentokines and exerkines.

Complications such as diabetes and preeclampsia can occur during pregnancy. Moderate-intensity exercise can prevent such complications by releasing placentokines and exerkines, such as apelin, adiponectin, leptin, irisin, and chemerin. Exercise and apelin increase thermogenesis and glucose uptake in pregnancy by activating AMPK, PI3K, PGC-1α, AKT1, UCP3, and sarcolipin.

Deep Learning for Size-Agnostic Inverse Design of Random-Network 3D Printed Mechanical Metamaterials.

Practical applications of mechanical metamaterials often involve solving inverse problems aimed at finding microarchitectures that give rise to certain properties. The limited resolution of additive manufacturing techniques often requires solving such inverse problems for specific specimen sizes. Moreover, the candidate microarchitectures should be resistant to fatigue and fracture.

Vitamin B reversed anxiety and depression induced by adolescent nicotine withdrawal through alteration the inflammatory, oxidative and serotoninergic profiles in male rats.

Background: The present study aims to assess the effect of vitamin B (Vit B) on depression-like behavior caused by nicotine (Nic) withdrawal, which is more likely due to the anxiogenic effect of Nic in adolescent male rats, through assessing behavioral and biochemical analysis.

Methods: Adolescent male rats were divided into vehicle (received normal saline), and experimental groups that received Nic (2 mg/kg, intraperitoneally (i.p.
