Prediction of the maximum oxygen consumption (VO) for young Saudi females using exercise parameters.

Background: Maximum oxygen consumption (VO), an essential indicator of integrated function of the cardiovascular, respiratory, and muscular systems, is an excellent predictor of all-cause morbidity and mortality. Direct measurement is a sophisticated procedure which for some individuals is difficult to perform. The use of international formulae leads to overestimation or underestimation of values.

Therefore, we aim to investigate the molecular mechanisms of Ns-induced cardiac hypertrophy, compare it with that induced by exercise training, and explore any possible synergistic effect of these two interventions.

Method: Twenty adult Wistar male rats were divided into control (C), Ns-fed (N.

Assessment of baroreceptor reflex sensitivity in young obese Saudi males at rest and in response to physiological challenges.

Unlabelled: Autonomic imbalance in overweight/obese persons could lead to an increased risk of cardiovascular complications including hypertension and arrhythmias. Baroreceptor reflex sensitivity is a sensitive indicator to detect an altered sympathovagal balance in overweight/obese individuals. This study investigated the effects of overweight/obesity on baroreceptor sensitivity in young Saudi males at rest and in response to physiological challenges.

Effects of α Deletion and Sickle-Cell Trait on Ventilatory and Hemodynamic Responses to Maximum Exercise in Young Saudi Females.

Introduction: Hemoglobinopathies are common disorders in Saudi Arabia and have an impact on the general health of the affected individuals. The current study aimed to find out the effects of the presence of α 3.7 kb rightward deletion or sickle-cell trait (SCT) on ventilatory and hemodynamic parameters of maximum exercise testing in young Saudi women.

Prevalence of Migraine and its Relationship with Psychological Stress and Sleep Quality in Female University Students in Saudi Arabia.

Purpose: This study aimed to determine the prevalence of migraine in young female adults and to identify if a relationship exists between psychological stress or poor sleep quality and migraine.

Materials And Methods: This case control study was carried out at Imam Abdulrahman Bin Faisal University (IAU), Dammam, KSA from March 2019 to March 2020 on 1,990 female students (17- to 26-years-old). The study tools were Migraine Screening Questionnaire (MS-Q), International Headache Society (IHS) Criteria for Migraine, K10 Psychological Distress Instrument (K10) and Pittsburgh Sleep Quality Index (PSQI).

Effects of Mobile Use on Subjective Sleep Quality.

Purpose: The objective of this study was to find out the association between mobile use and physiological parameters of poor sleep quality. It also aimed to find out the prevalence of mobile-related sleep risk factors (MRSRF) and their effects on sleep in mobile users.

Materials And Methods: This cross-sectional study was conducted on 1925 students (aged 17-23yrs) from multiple Colleges of Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia.

Protective Association of Single Nucleotide Polymorphisms rs1861868-FTO and rs7975232-VDR and Obesity in Saudi Females.

Background: Obesity is a major health threat worldwide. It predisposes individuals to diabetes, cardiovascular complications, and cancer. Genetic and environmental factors are responsible for the increasing incidence of obesity.

State-of-the-art tools unveil potent drug targets amongst clinically approved drugs to inhibit helicase in SARS-CoV-2.

Introduction: The extreme health and economic problems in the world due to the SARS-CoV-2 infection have led to an urgent need to identify potential drug targets for treating coronavirus disease 2019 (COVID-19). The present state-of-the-art tool-based screening was targeted to identify drug targets among clinically approved drugs by uncovering SARS-CoV-2 helicase inhibitors through molecular docking analysis.

Material And Methods: Helicase is a vital viral replication enzyme, which unwinds nucleic acids and separates the double-stranded nucleic acids into single-stranded nucleic acids.

Comparing levels of psychological stress and its inducing factors among medical students.

Objective: This study aimed to determine and compare degrees of psychological stress and inducing factors thereof among first to fifth year medical students (MS).

Methods: This cross-sectional study was conducted on 468 female MS. We used the Kessler 10 Psychological Distress Inventory consisting of questions on a range of stress-inducing factors.

Validity of maximal oxygen consumption prediction equations in young Saudi females.

To determine the applicability of Jones, Hansen, and Wasserman predictive equations for maximal oxygen consumption (VO2max) in Saudi females.  Methods: This cross-sectional study was conducted at Imam Abdulrahman Bin Faisal University, Dammam, Kingdom of Saudi Arabia, between March and May 2017. Maximal oxygen consumption was measured directly through the COSMED system for cardiopulmonary exercise testing in 102 girls with normal body mass index (19-25 years old).

Functional DNA variations associated with Saudi female with low VO: a pilot microarray study.

The study aims to explore the genetic predispositions and molecular pathways of low cardiorespiratory fitness (VO) in young Saudi females ( = 70). Young females were grouped based on the level of VO according to the specification of the physical fitness specialist certification as low VO (< 28.9; = 19) and high VO (> 33; = 14) and genotyped for 243345 putative functional exonic variants.
