The Correlation of Built Environment on Hypertension, and Weight Status amongst Adolescence in Saudi Arabia.
The prevalence of hypertension is becoming more common in children and adolescents than ever before. Thus, the aim of this study was to evaluate the associations between the built environment on physical activity, sedentary behaviour, waist circumference, and health amongst adolescents in Saudi Arabia. A systolic and diastolic blood pressure, resting heart rate and waist circumference of 380 boys and girls aged between 15-19 years old (male = 199 and females = 181) were measured. The International physical activity Questionnaire Short Form was used to assess the physical activity levels and time spent sitting. The statistical analysis conducted were means and standard deviation, 2-way and 3-way of variance (ANOVA), Bonferroni post hoc tests, Chi-squared distribution and Pearson's correlations. Among males, 16.75% were classified as hypertensive, 12.69% as pre-hypertensive, and 70.56% as normal whereas, females, 23.20% were classified as hypertensive, 12.15% as pre-hypertensive and 64.64% as normal. There were significant differences (F1,379 = 16.50, p 0.001) between males and females waist circumference. Pearson's correlation also revealed significant positive relationships in sedentary time (r = 0.123, p 0.016), WC (r = 0.104, p 0.043), and systolic blood pressure (r = 0.110, p 0.032). The results revealed that systolic and diastolic blood pressure are significantly related to multiple measures of weight status, and sedentary behaviour. The results also highlight that active youth had lower resting heart rate compared to inactive peers. The present findings provide a foundation of knowledge for future research and highlight the major need for research and policy interventions, to address the concerning health habits of Al-Ahsa youth and broader Kingdom of Saudi Arabia
The Impact of Environment on Physical Activity Levels and Obesity among Saudi Arabia Youth: Comparison of Urban; Rural Farm and Rural Desert Geographical Locations
Background: The inactive lifestyle is becoming prevalent in many developed and developing countries including Saudi Arabia. Thus, the aim of this study was to evaluate the impact of neighborhoods’ characteristics on physical activity (PA) levels and body mass index (BMI) in Saudi adolescents.
Methods: The anthropometric measurement of 380 secondary-school (boys = 199; girls = 181) from different geographical locations such as urban, rural farm and rural desert was taken using the Seca digital scales for weight and Seca portable measure for height. The BMI was calculated using the formula kg/m2 followed by participants wearing piezoelectric, New-Lifestyles NL-2000 PA Monitor, and completing the international physical activity short form questionnaire.
Results: The findings indicated, an average boys recorded 9180 steps per day compared to girls 5580 and the univariate ANOVA revealed a significant difference between genders steps per day in three geographical areas (F1,334 = 70.01, p < 0.001). The BMI results demonstrated that participant from rural farm had lower BMI (mean = 21.01 kg/m2) compared to urban location (mean = 24.12 kg/m2) and rural desert youth (mean = 25.58 kg/m2) indicating significant differences in BMI status in geographical locations (F2,379 = 16.40, p < 0.001).
Conclusion: The inactivity and obesity prevalence are prevalent amongst demographic groups in Al-Ahsa. Therefore, future policies and interventions could target this populations especially the rural desert youth in which the health risk could be higher

The volume of hydrogen gas involving was followed also in presence and absence of (PDA) in the corrosive solution .Accelerating enhanced by adding (NaCl , NaBr , NaI ) was also investigated
Evaluation of performance-based earthquake engineering in Yemen
Building codes follow a common concept in designing buildings to achieve an acceptable seismic performance. The objective underlying the concept is to ensure that the buildings should be able to resist minor earthquake without damage, resist moderate earthquake with some non-structural damage, and resist major earthquakes without collapse, but some structural as well as non-structural damage. This study aims to evaluate the performance-based seismic to come up with necessary recommendations for both future practices, essential review, and restoration of existing structures in Yemen. To do this real case studies incorporated, and nonlinear pushover analysis is carried out. The analysis results presented and then assessed to find out the conformity with the required performance. The structural sections assumed at the beginning of the design, then the design repeated many times to achieve the selected performance criteria (the plastic hinge properties and the maximum displacement)
Factors associated with HbA1c levels in poorly controlled type 2 diabetic patients in North-East Malaysia
Objective: A study was conducted at all the health centres in Kelantan in North-East Malaysia to determine the common factors associated with poor controlled of type 2 diabetic patients.
Design: A cross-sectional study
Materials and Methods: A total of 208 patients with poor diabetic control (HbA1c levels of more than 6.5%) were selected by stratified random sampling from all health centres in Kelantan. Socio-demographic data, physical examination, and fasting blood were taken from the patients to determine the related associated factors using multiple linear regression.
Results: The levels of HbA1c in the poorly controlled diabetic patients were significantly associated with fasting blood glucose (b=0.236, 95%CI=0.189,0.283), educational level (primary education: b=-0.965, 95%CI=-1.550,-0.380; secondary and tertiary education: b=-0.625, 95%CI=-1.228,-0.021), marital status (b=0.933, 95%CI=0.426,1.440) and patients receiving their care in health centres with Family Medicine Specialist (b=-0.495, 95%CI=-0.913,-0.076).
Conclusion: Fasting blood glucose and being married were associated with higher levels of HbA1c, while having had formal education and receiving diabetic care in health centres with Family Medicine Specialist were associated with lower levels of HbA1c in poorly controlled type 2 diabetic patients in Kelantan
EFFECT OF HERBICIDES ON GROWTH, GRAIN YIELD AND QUALITY OF BARLEY
This experiment was aimed to study the effect of   herbicide (lintur @180 g.ha-1 + Axial @1.5 L.ha-1, Navigator @ 1.25 L.ha-1 and the control treatment) in the companion weeds. Besides, grain yield and its components of three cultivars of barley (IPA 99, Buhooth 256, Aldebaran). The experiment was carried out according to RCBD, within split plot arrangement using three replicates. The cultivars represented the Main-plots, while herbicides and control treatments represented the sub-plots. The second included a laboratory experiment with four replicates of 50 seeds per replicate to study some grain quality characteristics resulting from the first field experiment. The results were showed the superiority of the Buhooth 256 cultivar in number of spikes, weight of 1000 grains, and the grain yield with an average of 495.10 spike.m-2, 22.23 g, and 1.46 ton.ha-1, respectively. Buhooth 256 also recorded the best results in increasing the percentage of weed control, reducing weed dry weight, and increasing the inhibition ratio. The same cultivar exceeded in most characteristics of grain quality. The treatment of herbicides (lintur + Axial) exceeded by achieving the highest average number of spikes of (471.60 spike.m-2), and the highest number of grains per spike with (51.77 grain.spike-1). Coupled with the weight of 1000 grains (21.47 g), and the highest grain yield (1.53 ton.ha-1)
Change in hematologic indices over time in pediatric inflammatory bowel disease treated with azathioprine
Azathioprine leads to changes in mean corpuscular volume (MCV) and white blood cell (WBC) indices reflecting efficacy or toxicity. Understanding the interactions between bone marrow stem cells and azathioprine could highlight abnormal response patterns as forerunners for hematologic malig-nancies. This study gives a statistical description of factors influencing the relationship between MCV and WBC in children with inflammatory bowel disease treated with azathioprine. We found that leukopenia preceded macro¬cytosis. Macrocytosis is therefore not a good predictor of leukopenia. Further studies will be necessary to determine the subgroup of patients at increased risk of malignancies based on bone marrow response
Anxiolytic, Antidepressant-Like Proprieties and Impact on the Memory of the Hydro-Ethanolic Extract of Origanum majorana L. on Mice
Marjoram (Origanum majorana L.) infusion has been used as folk medicine against depression and anxiety. However, no studies have been carried out yet to prove those activities scientifically. In this study, the anxiolytic, antidepressant-like effects, and memory impact of the hydro-ethanolic extracts of marjoram were evaluated in mice. The hydro-ethanolic extracts (250 and 500 mg/kg) were evaluated for their central nervous effect using six different behavioral tests such as light–dark box (LDB) and open field (OF) for anxiety, forced swim test (FST), and tail suspension test (TST) for depression, and object recognition test (ORT), Morris water maze (MWM) for the impact on memory. The experiments were realized on days 1, 7, 14, and 21 of treatments and compared with bromazepam for anxiety (1 mg/kg) and paroxetine for depression (11.5 mg/kg). The phytochemical screening was performed by HPLC, and the acute and sub-acute toxicities were performed following OCED guidelines (N°423 and 407) with biochemical parameters evaluation and histopathological analysis. Oral administration of marjoram hydro-ethanolic extract induced significant anxiolytic and antidepressant-like effects without memory impairment, increasing the exploration and time spent in the light area in the LDB test in a similar way to that of bromazepam. In the FST and TST, the extract was as effective as paroxetine (11.5 mg/kg, p.o.) in reducing immobility. The phytochemical screening showed the presence of ferulic acid, naringin, hydroxytyrosol, geraniol, and quercetin. This study approves the traditional use of this plant and encourages further investigation on its bioactive compounds
