The influence of motivational climate on the physical activity adherence among junior high school students: The mediating effect of achievement goal orientation.

In this study, which was based on the theories of motivational climate and achievement goal orientation, an experimental intervention was conducted on 82 junior high school students using the Motivational Climate Scale (MCSYS), Task and Ego Orientation in Sport Questionnaire (TEOSQ), and Physical Activity Persistence Scale. The aim was to explore the influence of different motivational climates in physical education classes on the physical activity adherence among junior high school students and examine the mediating role of achievement goal orientation. The results revealed the following significant findings: Firstly, there was a noteworthy positive correlation between the physical activity adherence among junior high school students, the motivational climate, and achievement goal orientation.

The effect of intergenerational rearing on young children's self-control: The intervention effect of sports games.

Objective: To investigate the effect of different rearing arrangements on children's self-control and verify the promoting effect sports games might have on children's self-control in intergenerational rearing.

Methods: A total of 72 intergenerational rearing children and 66 non-intergenerational rearing children were included in Experiment 1, in which the delay-of-gratification task was used to examine the differences in self-control among children with different rearing arrangements. In experiment 2, 70 intergenerational rearing children were included as subjects, and sports games were used to improve their self-control.

The Influence of Mixed Teaching Mode on the Learning Effects of Psychology Students' Experiment Course in Higher Vocational Colleges.

In this paper, we are going to analyze the influence of mixed teaching mode on the teaching effect of psychology students' experiment courses in higher vocational colleges. To realize and verify these claims, 80 psychology students of grade 2020 in our school were selected for observation. Class 1 of the psychology major in our school was randomly selected as the observation group ( = 40) and Class 2 as the control group ( = 40).

Metabolic rate and substrate oxidation of young males with obesity at the different sleep stages.

Objective: Insufficient and poor-quality sleep among young adults is closely related to obesity and may impact metabolic processes. The mobilization and use of endogenous substrates during sleep, especially fat oxidation, is essential for energy metabolism. This study investigated whether there are differences in sleep structure, metabolic rate, substrate oxidation, and the respiratory quotient (RQ) between young males with normal weight and obesity according to sleep stages and overnight sleep.

Abnormal expression of FAK and paxillin correlates with oral cancer invasion and metastasis.

Globally, the tenth most common cancer is the oral squamous cell carcinoma (OSCC) and the treatment strategy for improving of OSCC patients survival rate still remains a challenging one. Aberrant regulation of cell to extracellular matrix protein interactions leads to progression of human cancers. The focal adhesion kinase (FAK) and its downstream target paxillin have been implicated in cancer growth, migration, invasion and metastasis of different cancers.

Resting Energy Expenditure, Fetal Biometric Parameters by Ultrasound, and Birthweight in Chinese Pregnant Women With Gestational Diabetes Mellitus.

Objectives: To explore the relationships between resting energy expenditure (REE) according to indirect calorimetry, fetal biometric parameters by ultrasound, and birthweight in gestational diabetes mellitus (GDM).

Methods: Sixty-five women with GDM and 60 in the control group were enrolled. The REE, birthweight, and fetal biometric parameters according to ultrasound, including biparietal diameter, head circumference, abdominal circumference (AC), and femur length, were measured.

Treadmill exercise ameliorates chronic REM sleep deprivation-induced anxiety-like behavior and cognitive impairment in C57BL/6J mice.

Various sleep disorders have deleterious effects on mental and cognitive performance. Exercise, as an alternative therapeutic strategy, exerts beneficial impacts on human health. In the present study, we aimed to evaluate the effects of 4 weeks treadmill exercise (4W-TE) on anxiety-like behavior and cognitive performance in mice exposed to 2 months REM sleep deprivation (2M-SD) (20 h per day).

Diagnosis of Compressed Nerve Root in Lumbar Disc Herniation Patients by Surface Electromyography.

Objective: To establish a logistic regression model using surface electromyography (SEMG) parameters for diagnosing the compressed nerve root at L or S level in patients with lumbar disc herniation (LDH).

Methods: This study recruited 24 patients with L nerve root compression and 23 patients with S nerve root compression caused by LDH from May 2014 to May 2016. SEMG signals from the bilateral tibialis anterior and lateral gastrocnemius were measured.

Algorithm to improve accuracy of energy expended in a room calorimeter.

The whole-room indirect calorimeter is considered as important equipment for human energy expenditure measurement, but noise reduction in the system remains a challenge. A selective filtering method (SFM) was designed to improve the accuracy of the computation of O consumption rate ([Formula: see text]) and CO production rate ([Formula: see text]), based on two facts: (1) the rapid changes of [Formula: see text], [Formula: see text] and respiratory quotient (RQ) in human should be accompanied by physical activity; (2) the oxygen consumption and the carbon dioxide production should not be negative because living humans do not generate oxygen, nor consume carbon dioxide. The performance of SFM was compared with the moving average method, the central difference method and the wavelet de-noising method.

Energetic Assessment of the Nonexercise Activities under Free-Living Conditions.

Nonexercise activities (NAs) are common types of physical activity in daily life and critical component in energy expenditure. However, energetic assessment of NA, particularly in free-living subjects, is a technical challenge. In this study, mechanical modeling and portable device were used to evaluate five common types of NA in daily life: sit to stand, lie to sit, bowing while standing, squat, and right leg over left.

[Mechanism of chloroquine in promoting sensitivity of chemotherapeutics in oral squamous cell carcinoma CAL-27 cell line to cisplatin].

Purpose: To study the role and mechanism of autophagy in chemotherapy of oral squamous cell carcinoma, and provide theoretical evidence to improve chemotherapeutic efficacy of oral squamous cell carcinoma patients.

Methods: The cell survival rate changes induced by cisplatin (DDP) and chloroquine (CQ) in CAL-27 cells were assayed by methyl thiazolyl tetrazolium method(MTT). The LC3-II expression level was detected by laser scanning confocal microscope; The apoptotic rate was determined by flow cytometry.

[Study of exercise heart rate variability based on correlation dimension].

This paper is mainly devoted to the relationship between the correlation dimension (CD) of exercise heart rate variability (EHRV) and the status of cardiovascular function. Hypertensive patients and healthy people were enrolled in two contrast groups. Dynamic electrocardiograph (ECG) in step exercise was recorded.

[Value of three-dimensional contrast-enhanced magnetic resonance angiography in the diagnosis of mesenteric arteriosclerosis].

Objective: To assess the clinical value of three-dimensional contrast-enhanced magnetic resonance angiography (3D-CE-MRA) in the diagnosis of mesenteric arteriosclerosis.

Methods: 3D-CE-MRA of the mesenteric arteries was performed in 21 patients with 23 healthy subjects as the control. After 3D image reconstruction and maxi intense projection, and the abnormalities of the mesenteric arteries were observed and analyzed.
