Impact of spinach thylakoid extract-induced 12-week high-intensity functional training on specific adipokines in obese males.

Background: Obesity presents multifarious etiopathologies with its management being a global challenge. This article presents the first ever report on the impact of spinach thylakoid extract-induced high-intensity functional training (HIFT) on obesity management via regulating the levels of novel adipokine, C1q/TNF-related Protein-12 (CTRP-12), furin, and Krüppel-like factor 15 (KLF-15).

Methods: Sixty-eight obese male subjects were randomly divided into four groups: control group (CG), supplement group (SG), training group (TG), and the combined training and supplement group (TSG).

Satiety: a gut-brain-relationship.

Many hormones act on the hypothalamus to control hunger and satiety through various pathways closely associated with several factors. When food is present in the gastro intestinal (GI) tract, enteroendocrine cells (EECs) emit satiety signals such as cholecystokinin (CCK), glucagon like peptide-1 (GLP-1) and peptide YY (PYY), which can then communicate with the vagus nerve to control food intake. More specifically, satiety has been shown to be particularly affected by the GLP-1 hormone and its receptor agonists that have lately been acknowledged as a promising way to reduce weight.

Electromyogram Power Spectrum and Cardiac Function Changes After Combined Aerobic Interval Training and Inspiratory Muscle Training in Chronic Heart Failure Patients.

Exercise intolerance and dyspnea are the major symptoms of patients with chronic heart failure (CHF) and are associated with a poor quality of life. In addition to impaired central hemodynamics, symptoms may be attributed to changes in peripheral skeletal muscles. This study aimed to evaluate the effects of aerobic interval training (AIT) combined with inspiratory muscle training (IMT) on cardiac and skeletal muscle function and on functional capacity and dyspnea in patients with CHF and inspiratory muscle weakness.

A randomized controlled trial of high-intensity interval training and inspiratory muscle training for chronic heart failure patients with inspiratory muscle weakness.

Objectives: Chronic heart failure is a major public health problem in which supervised exercise programs are recommended as part of non-pharmacological management. There are various reports of the success of high-intensity aerobic interval training (HI-AIT) and inspiratory muscle training (IMT) in the management of chronic heart failure patients. This study tested the hypothesis that the combination of HI-AIT and IMT could result in additional benefits over the IMT and the HI-AIT alone in terms of inspiratory muscle function, exercise capacity, and quality of life in patients with chronic heart failure and inspiratory muscle weakness.

Does the perigestational exposure to chlorpyrifos and/or high-fat diet affect respiratory parameters and diaphragmatic muscle contractility in young rats?

The perinatal period is characterized by developmental stages with high sensitivity to environmental factors. Among the risk factors, maternal High-Fat Diet (HFD) consumption and early-life pesticide exposure can induce metabolic disorders at adulthood. We established the effects of perigestational exposure to Chlorpyrifos (CPF) and/or HFD on respiratory parameters, sleep apnea and diaphragm contractility in adult rats.

Data on dysfunctional muscle contraction and genes contractile expression associated with chlorpyrifos exposure in slow twitch skeletal muscle.

Chlorpyrifos (CPF) is a toxic organophosphate commonly used worldwide. Its residues are being detected in different environmental matrixes and hence in the food chain. Repeated CPF exposure might pose health risk for the general population on long term.

Effect of Leishmaniasis on the Performance of Elementary School Students: A Case Study among Syrian Refugees in Some Bekaa (Lebanon) Area Schools.

Since the Syrian conflict started, Lebanon became a common destination receiving a huge number of Syrian refugees that are living in camps spread all over the country, with the largest concentration in the Bekaa Valley. Generous steps are being taken to increase the access to formal education, such as offering free public education and opening second shifts in the public schools in the afternoon. Yet barriers, such as child labor and health-related factors like the spreading of some communicable diseases, like , are keeping children out of classroom.

Impacts of prolonged chlorpyrifos exposure on locomotion and slow-and fast- twitch skeletal muscles contractility in rats.

Aim: Investigate the effect of dietary exposure to chlorpyrifos on locomotion and contraction of soleus and () involved in locomotion. Methods: Rats were fed diets containing 1 or 5 mg kg of chlorpyrifos for six weeks. Locomotion has been assessed weekly using beam walking and beam balance tests.

Best mode of inspiratory muscle training in heart failure patients: a systematic review and meta-analysis.

Objectives The objective of this study was to evaluate the effects of inspiratory muscle training on inspiratory muscle strength, functional capacity and dyspnoea for patients with chronic heart failure, by summarising the published research on the effects of inspiratory muscle training. To identify the best mode of intervention in terms of: the load of maximal inspiratory pressure; the frequency of sessions; and the total duration of intervention. Methods A relevant literature research using the PubMed database, Cochrane and references of published studies, from 1998 to 2016, was conducted.

Impact of chronic exposure to the pesticide chlorpyrifos on respiratory parameters and sleep apnea in juvenile and adult rats.

The widely used organophosphorus pesticide chlorpyrifos (CPF) is often detected in food. CPF inhibits acetylcholinesterase and can modify muscle contractility and respiratory patterns. We studied the effects of chronic exposure to CPF on respiratory parameters and diaphragm contractility in 21- and 60-days old rats.

Hippocampal sharp wave/ripples during sleep for consolidation of associative memory.

The beneficial effect of sleep on memory has been well-established by extensive research on humans, but the neurophysiological mechanisms remain a matter of speculation. This study addresses the hypothesis that the fast oscillations known as ripples recorded in the CA1 region of the hippocampus during slow wave sleep (SWS) may provide a physiological substrate for long term memory consolidation. We trained rats in a spatial discrimination task to retrieve palatable reward in three fixed locations.

Sustained increase in hippocampal sharp-wave ripple activity during slow-wave sleep after learning.

High-frequency oscillations, known as sharp-wave/ripple (SPW-R) complexes occurring in hippocampus during slow-wave sleep (SWS), have been proposed to promote synaptic plasticity necessary for memory consolidation. We recorded sleep for 3 h after rats were trained on an odor-reward association task. Learning resulted in an increased number SPW-Rs during the first hour of post-learning SWS.

Sleep apnea is induced by a high-fat diet and reversed and prevented by metformin in non-obese rats.

Objective: We assessed the relationship between a high-fat (HF) diet and central apnea during rapid eye movement and non-rapid eye movement sleep stages by recording ventilatory parameters in 28 non-obese rats in which insulin resistance had been induced by an HF diet. We also studied whether metformin (an anti-hyperglycemic drug frequently used to treat insulin resistance) could reverse sleep apnea or prevent its occurrence in this experimental paradigm.

Research Methods And Procedures: Rats were fed with a standard diet (10 rats), an HF diet (8 rats), or an HF diet concomitantly with metformin treatment (10 rats).

Spontaneous motor activity in fat-fed, streptozotocin-treated rats: a nonobese model of type 2 diabetes.

We investigated the effects of diabetes on the spontaneous motor activities (SMA) of streptozotocin-treated rats fed a high-fat diet (HFD), a new nonobese model of type 2 diabetes. The daily changes in the duration of SMA were assessed via infrared cells, which detected all movements of rats that had been fed for 3 weeks with a standard or HFD and then injected with vehicle or 50 mg/kg of streptozotocin. Five to six days after streptozotocin injection, the daily body weight and the levels of duration of SMA of the diabetic rats were depressed, manifest by a substantial decline in the frequency of occurrence of nocturnal SMA episodes.

Effect of high-fat diet and metformin treatment on ventilation and sleep apnea in non-obese rats.

We investigated the effect of insulin resistance on ventilation and the incidence of sleep apnea in non-obese rats and determined whether metformin could change ventilation and occurrence of sleep apneas. Five groups of rats were studied: (1) standard chow; (2) high-fat groups, with 1 with metformin; (2) had type 2 diabetes induced by streptozotocin, with 1 with metformin. Compared to standard rats, ventilatory parameters remained unchanged in the high-fat fed diet as well as in diabetic rats.

Liver temperature during sleep.

Study Objective: The liver, like brown adipose tissue, is an important source of nonshivering thermogenesis. We tested the hypothesis that the thermal state of the liver is preserved during slow wave sleep but deteriorates during paradoxical sleep.

Methods: Twelve adult male Wistar rats were equipped with electrodes and thermistor probes--which measured cortical (Tco), interscapular brown adipose tissue (Tibat), and liver (Tl) temperatures--for thermal and sleep studies.
