Abstract
Insufficient physical activity is considered a strong risk factor associated with non-communicable diseases. This study aimed to assess the impact of COVID-19 on physical (in)activity behavior in 10 Arab countries before and during the lockdown. A cross-sectional study using a validated online survey was launched originally in 38 different countries. The Eastern Mediterranean regional data related to the 10 Arabic countries that participated in the survey were selected for analysis in this study. A total of 12,433 participants were included in this analysis. The mean age of the participants was 30.3 (SD, 11.7) years. Descriptive and regression analyses were conducted to examine the associations between physical activity levels and the participants' sociodemographic characteristics, watching TV, screen time, and computer usage. Physical activity levels decreased significantly during the lockdown. Participants' country of origin, gender, and education were associated with physical activity before and during the lockdown (p < 0.050). Older age, watching TV, and using computers had a negative effect on physical activity before and during the lockdown (p < 0.050). Strategies to improve physical activity and minimize sedentary behavior should be implemented, as well as to reduce unhealthy levels of inactive time, especially during times of crisis. Further research on the influence of a lack of physical activity on overall health status, as well as on the COVID-19 disease effect is recommended.

Abstract
Objective: Cardiovascular disease (CVD) is the leading cause of disability and death in many countries. Together with CVD, Type 2 diabetes mellitus (T2DM) accounts for more than 80% of all premature non-communicable disease deaths. The protective effect of the Mediterranean diet (MedDiet) on CVD and its risk factors, including T2DM, has been a constant topic of interest. Notwithstanding, despite the large body of evidence, scientists are concerned about the challenges and difficulties of the application of MedDiet. This review aims to explore the motivations and challenges for using MedDiet in patients with CVD and T2DM. Design: An electronic search was conducted for articles about MedDiet published in PubMed, ScienceDirect, Scopus, and Web of Science up to December 2021, particularly on CVD and T2DM patients. From a total of 1536 studies, the final eligible set of 108 studies was selected. Study selection involved three iterations of filtering. Results: Motivation to apply MedDiet was driven by the importance of studying the entire food pattern rather than just one nutrient, the health benefits, and the distinct characteristics of MedDiet. Challenges of the application of MedDiet include lacking universal definition and scoring of MedDiet. Influences of nutritional transition that promote shifting of traditional diets to Westernized diets further complicate the adherence of MedDiet. The challenges also cover the research aspects, including ambiguous and inconsistent findings, the inexistence of positive results, limited evidence, and generalization in previous studies. The review revealed that most of the studies recommended that future studies are needed in terms of health benefits, describing the potential benefits of MedDiet, identifying the barriers, and mainly discussing the effect of MedDiet in different populations. Conclusions: In general, there is consistent and strong evidence that MedDiet is associated inversely with CVD risk factors and directly with glycemic control. MedDiet is the subject of active and diverse research despite the existing challenges. This review informs the health benefits conferred by this centuries-old dietary pattern and highlights MedDiet could possibly be revolutionary, practical, and non-invasive approach for the prevention and treatment CVD and T2DM.

Abstract
Vitamin or mineral supplementation is considered to be the most commonly used medical treatment for autism spectrum disorder (ASD), in addition to other interventions such as neurological and psychological interventions. There is not much evidence of therapeutic efficacy between vitamin and mineral supplementation and improvements in ASD. However, several researchers have noted that patients with ASD have various metabolic and nutritional abnormalities including issues with sulfation, methylation, glutathione redox imbalances, oxidative stress, and mitochondrial dysfunction. There is some evidence that vitamin and mineral supplementation may support these basic physiologic processes. Recently, the nutritional status of ASD patients has been gaining focus in this particular area. Pointing out the nutritional status as a potential etiological factor for attention/communication disorders, more importance has been given to this particular point. Moreover, autistic specific considerations like the feature and behavior of ASD might be increased or at least fall in the higher risk due to the sub-optimal nutritional status.

Abstract
Background: Colorectal cancer (CRC) represents a heterogeneous group of diseases characterized by uncontrolled growth and spread of abnormal cells in the body. CRC vary on the basis of both the biologic features of the disease and its associated lifestyle characteristics. The risk of CRC increases with several modifiable factors including obesity, physical inactivity, a diet high in red or processed meat, heavy alcohol consumption, and possibly inadequate intake of fruits and vegetables. We aimed to establish a baseline data for dietary and lifestyle characteristics of Omani adults diagnosed with CRC. Methods: A Case control study conducted at Sultan Qaboos University Hospital, a referral hospital for CRC patients in Oman, and included 279 subjects (109 diagnosed CRC cases and 170 matched controls). All study subjects were recruited on volunteer basis and personally interviewed for preset questions related to sociodemographic data, anthropometric assessment, dietary intake and physical activity. Results: There was no significant difference between cases and controls regarding smoking, alcohol intake, physical activity and dietary fiber intake. However the enrolled cases were more overweight (OR =3.27. 95% CI: 1.91, 7.27), and, had a higher caloric (p =0.001) and macronutrient intake (carbohydrate: p = 0.001; protein: p = 0.017; saturated fat: P = 0.034) than the controls. In addition, the dietary pattern of the cases was characterized by a trend towards low vegetables and fruits intake. Conclusion: CRC maybe prevented through dietary management of high risk groups. This primary prevention approach will ultimately reduce the burden of CRC in Oman.

Abstract
Purpose Literature emerging from Western countries has reported increased levels of serum oxidative stress markers among polycystic ovarian syndrome (PCOS) women. In the Arab region, there is limited research about the association between oxidative stress and PCOS. This study aimed to compare sociodemographic and clinical characteristics, sex hormones, and oxidative stress indices between PCOS women and non-PCOS women and to investigate the correlation between oxidative stress biomarkers and sex hormones. Methods This hospital-based case-control study was conducted among reproductive-aged women. The study included 51 women diagnosed with PCOS (as per Rotterdam 2003 criteria) and 45 control women who were not diagnosed with PCOS. Serum samples were collected to measure the mean levels of the following sex hormones: total testosterone, dehydroepiandrosterone sulfate, estradiol and progesterone, as well as to measure biomarkers of oxidative stress including glutathione peroxidase (GPx), glutathione reductase (GR), glutathione (GSH), and total antioxidant capacity (TAC). Results PCOS women exhibited clinical characteristics including irregular menses, hirsutism, and acne compared to the control group (P≤0.05). Significant differences were observed in the waist-hip ratio of PCOS women compared to controls (P=0.004). GPx and GR activity levels appeared to be higher among PCOS women compared to controls; however, no statistically significant differences were observed between the two groups (P>0.05). PCOS women had lower GSH and TAC levels compared to controls with a statistically significant difference observed for GSH levels (P=0.006). Correlation analysis showed a significant negative correlation between estradiol and TAC in the total sample (r=-0.284, P=0.005). Conclusion This study provides supportive evidence that oxidative stress might play a role in the pathogenesis of PCOS and, hence, oxidative stress parameters could be suggested as diagnostic markers for early diagnosis of high-risk groups. Also, the study provides supportive evidence that obesity and sex hormones, particularly estradiol, in PCOS may contribute to enhanced oxidative stress.

Abstract
Purpose Previous studies in Euro-American populations have shown that women with polycystic ovarian syndrome (PCOS) have increased levels of “psychological burden”. While PCOS has been reported in Arab countries such as Oman, there is a dearth of studies of the occurrence of psychological burden among PCOS women in the Arab region. This study aimed to compare sociodemographic and clinical characteristics of PCOS women diagnosed with non-PCOS women and prevalence of severity of depression, anxiety and stress and to explore the association between PCOS and indices of psychological disturbances after adjusting for potential confounding factors. Patients and methods This hospital-based case–control study was conducted among women aged 16–49 years. The study included 52 women diagnosed with PCOS (as per Rotterdam 2003 criteria) and 60 control who were PCOS-free. The presence of psychological burden – depression, anxiety and stress – was quantified using Depression, Anxiety and Stress Scale-21 (DASS-21). Results The crude odds ratios (ORs) generated by logistic regression models indicated an increased risk of depression, anxiety and stress among women with PCOS compared to controls. The adjusted OR also indicated an increased risk of depression (OR =1.10; 95% confidence interval [CI] 0.50, 2.43), anxiety (OR =1.09; 95% CI 0.47, 2.52) and stress (OR =1.45; 95% CI 0.68, 3.12), However, no statistical differences were observed along the three psychological distresses (p>0.05) between the two study groups. Conclusion The study indicates that the presence of PCOS is associated with an increased risk of psychological burden. If this study will withstand further scrutiny, meeting psychological needs of such population would need to be contemplated.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is caused by fat accumulation and is associated with oxidative stress. In this study, we investigated the potential protective effect of pomegranate (Punica granatum L.) peel extract (PPE) against oxidative stress in the liver of rats with NAFLD. Sprague-Dawley rats were fed a high fat diet (HFD), 20% corn oil, or palm oil for 8 weeks in the presence or absence of PPE. The control group was fed a basal diet. The progression of NAFLD was evaluated histologically and by measuring liver enzymes (alanine transaminase and aspartate transaminase), serum lipids (triglycerides and total cholesterol), and oxidative stress markers. The HFD feeding increased the body weight and caused NAFLD, liver steatosis, hyperlipidemia, oxidative stress, and elevated liver enzymes. Administration of PPE ameliorated the hepatic morphology, reduced body weight, improved liver enzymes, and inhibited lipogenesis. Furthermore, PPE enhanced the cellular redox status in the liver tissue of rats with NAFLD. Our findings suggest that PPE could improve HFD-induced NAFLD via abolishment of hepatic oxidative damage and hyperlipidemia. PPE might be considered as a potential lead material in the treatment of NAFLD and obesity through the modulation of lipid metabolism.

Abstract
We are currently witnessing a dramatic change in lifestyle and food choices that is accompanied with an increase in the rate of morbidity and mortality from cardiovascular diseases (CVD). Although studies have reported an association of CVD with hyperhomocysteinemia-mediated oxidative stress, the biochemical basis is not known. This case-control study was aimed to evaluate the nutritional and biochemical status of B-vitamins in relation to hyperhomocysteinemia and oxidative stress in newly diagnosed cardiac patients. The retrospective dietary intake of the study subjects (cases and controls) was estimated using a semi-quantitative food frequency questionnaire, and fasting blood samples were drawn to assess their serum levels of B-vitamins (folate, vitamins B6 and B12), homocysteine (HCY), and oxidative stress indices such as glutathione (GSH), total antioxidant capacity (TAC), malondialdehyde (MDA), and nitrites and nitrates (NN). It was observed that the cases had a lower dietary intake of B-vitamins as compared to their matched control subjects as well as to the corresponding recommended dietary allowances. Biochemical analysis of cases, as compared to controls, indicated depletion of GSH, impairment of TAC, and an elevation in the serum levels of HCY, MDA, and NN. These results suggest that lower status (dietary intake and serum levels) of B-vitamins is involved in the etiology of hyperhomocysteinemia and oxidative stress, the typical risk factors for CVD.

Abstract
Particulate air pollution (PAP) exposure is associated with increased morbidity and mortality, particularly in patients with renal disease. However, there are only a few studies on the interaction between PAP and renal injury, and none on agents that may ameliorate it. We studied the interaction between cisplatin (CP) nephrotoxicity and a single exposure to diesel exhaust particle (DEP) in rats 24 h before sacrifice, and assessed the effect of co-treatment with the active ingredient in Nigella Sativa seed oil, thymoquinone (TQ) thereon. Rats were injected intraperitoneally with CP (6 mg/kg) and four days later, they were exposed intratracheally to DEP (0.5 mg/kg), and were sacrificed 24 h later. Oral TQ (20 mg/kg) was given daily throughout the experimental period. CP alone caused several physiological, biochemical, and histopathological changes that included reduced growth and creatinine clearance, and raised plasma neutrophil gelatinase-associated lipocalin (NGAL), interleukin 6 (IL-6) and C-reactive protein (CRP), creatinine and urea concentrations, and urinary N-acetyl-b-D-glucosaminidase (NAG) activities. It adversely affected several indices of oxidative damage in the kidneys, and induced renal tubular necrosis. Most of these actions were significantly potentiated in rats given both CP and DEP. TQ significantly abrogated many of the effects of CP and DEP, given alone and in combination. These results provide experimental evidence that subjects with renal diseases can be at higher risk from PAP, and that TQ, pending further pharmacological and toxicological studies, can be considered a useful agent in patients with renal diseases and exposed to PAP.

Abstract
Chrysin (5, 7- dihydroxyflavone) is a flavonoid with several pharmacological properties that include antioxidant, anti-inflammatory and antiapoptotic activities. in this work, we investigated some effects of three graded oral doses of chrysin (10, 50 and 250 mg/kg) on kidney structure and function in rats with experimental chronic renal disease (CKD) induced by adenine (0.25% w/w in feed for 35 days), which is known to involve inflammation and oxidative stress. Using several indices in plasma, urine and kidney homogenates, adenine was found to impair kidney function as it lowered creatinine clearance and increased plasma concentrations of creatinine, urea, neutrophil gelatinase-associated lipocalin and N-Acetyl-beta-D-glucosaminidase activity. Furthermore, it raised plasma concentrations of the uremic toxin indoxyl sulfate, some inflammatory cytokines and urinary albumin concentration. Renal morphology was severely damaged and histopathological markers of inflammation and fibrosis were especially increased. In renal homogenates, antioxidant indices, including superoxide dismutase and catalase activities, total antioxidant capacity and reduced glutathione were all adversely affected. Most of these adenine – induced actions were moderately and dose -dependently mitigated by chrysin, especially at the highest dose. Chrysin did not cause any overt adverse effect on the treated rats. The results suggest that different doses of chrysin produce variable salutary effects against adenine-induced CKD in rats, and that, pending further pharmacological and toxicological studies, its usability as a possible ameliorative agent in human CKD should be considered.

Abstract
The present study was conducted to assess the status of vitamin C among healthy young adults in relation to serum antioxidant parameters [glutathione (GSH), thiols, and total antioxidant capacity, (TAC)], and oxidative stress markers [malondialdehyde (MDA), and nitrites plus nitrates (NN)]. A prospective study included 200 young adults, and their dietary intake was assessed by using food diaries. Fasting plasma vitamin C, serum levels of GSH, thiols, TAC, MDA, and NN were measured using biochemical assays. It was observed that 38% of the enrolled subjects, n=76, had an adequate dietary intake of vitamin C (ADI group). Meanwhile, 62%, n=124, had a low dietary intake of vitamin C (LDI group) as compared to the recommended dietary allowances. The fasting plasma level of vitamin C was significantly higher in the ADI group as compared to the LDI group. Oxidative stress in the sera of the LDI group was evidenced by depletion of GSH, low thiols levels, impairment of TAC, an elevation of MDA, and increased NN. In the ADI group, positive correlations were found between plasma vitamin C and serum antioxidant parameters (GSH, thiols, and TAC). Meanwhile, the plasma vitamin C was negatively correlated with serum MDA and NN levels. This study reveals a significant increase of oxidative stress status and reduced antioxidant capacity in sera from healthy young adults with low intake of the dietary antioxidant, vitamin C.

Abstract
BACKGROUND/AIMS Water-pipe smoking (WPS) is popular in the Middle East and is starting to gain popularity in several Western countries as well. It is widely and erroneously perceived to be less harmful than other forms of tobacco use. The reproductive adverse effects of cigarette smoking have been studied before with conflicting results, but data on the possible adverse reproductive effects of WPS are lacking. Here, we assessed the effects of nose-only exposure to mainstream WPS generated by commercially available honey-flavored "moasel" tobacco in mice. METHODS The duration of the session was 30 min/day for one month. Control mice were exposed to air. Twenty-four h after the last exposure, mice were killed and the testes and plasma removed for analysis. In testicular homogenates total protein, alkaline phosphatase activity, several indices of oxidative damage and Vascular Endothelial Growth Factor Receptor 2 (VEGFR2) were quantified. The plasma concentrations of leptin, testosterone, estrogen and luteinizing hormone (LH) were also measured. Histological analysis of testes and lungs was also conducted. RESULTS WPS caused statistically significant decreases in the plasma concentrations of leptin, testosterone, and LH, and in the concentrations of total protein and the antioxidant indices measured. A statistically non-significant decrease in VEGFR2 protein in the WPS--exposed mice compared to the control mice was also found. The body and testicular weights of mice exposed to WPS, as well as their testicular alkaline phosphatase activity and light microscopic histology, and plasma estrogen concentration were all not significantly affected by WPS. CONCLUSION Further studies on the functional implications of these findings in mice exposed to WPS for longer durations are warranted.

Abstract
The elderly population is increasing worldwide and it has been suggested that senior citizens will continue to constitute the bulk of the population in many countries. Nutritional status of senior citizens are adversely affected by their frailty, chronic condition and declining cognitive functioning. Conversely, malnourished elderly further deteriorate their frailty, chronic disease and cognitive functioning. The aim of this review article is to recognize the importance of nutritional assessment of elderly population particularly those with cognitive impairment. First part is to highlight characteristic cognitive impairment among senior citizens and the second one highlight t he background in which malnutrition is a factor that leads to increased risk of morbidity and mortality in the elderly. This review also highlight salgorithms for safeguarding nutritional status among senior citizen and focuses on importance of nutritional screening, assessment and early intervention for safeguarding further deterioration of elderly who are likely to prone to cognitive impairment.

Abstract
To investigate the effect of gamma-aminobutyric acid (GABA) on acute renal injury (ARI), we used here a rat model of acute tubular necrosis induced by the anticancer drug cisplatin (CP). GABA was given orally (100 or 500 mg/kg/day for ten consecutive days), and on the 6th day, some of the treated rats were also injected intraperitoneally with either saline or CP (6 mg/kg). Four days after CP treatment, urine was collected from all rats, which were then anaesthetized for blood pressure and renal blood flow monitoring. This was followed by intravenous injection of norepinephrine for the assessment of renal vasoconstrictor responses. Thereafter, blood and kidneys were collected for measurement of several functional, biochemical and structural parameters. GABA treatment (at 500 but not 100 mg/kg) significantly mitigated all the measured physiological and biochemical indices. Sections from saline- and GABA-treated rats showed apparently normal proximal tubules. However, kidneys of CP-treated rats had a moderate degree of necrosis. This was markedly lessened when CP was given simultaneously with GABA (500 mg/kg). The concentration of platinum in the cortical tissues was not significantly altered by GABA treatment. The results suggested that GABA can ameliorate CP nephrotoxicity in rats. Pending further pharmacological and toxicological studies, GABA may be considered a potentially useful nephroprotective agent in CP-induced ARI.

Abstract
Aluminum (Al) is an environmental toxin that induces oxidative stress in neuronal cells. Mushroom cultivar extract (MCE) acted as a potent antioxidant agent and protects against cellular oxidative stress in human cultured neuronal cells. This study aimed to investigate the neuroprotective effect of MCE against Al-induced neurotoxicity in rat brain. Forty Sprague-Dawley rats were divided into 4 groups (10 rats per group), control group, MCE-fed group, Al-administered group and MCE/Al-treated group. Animals were continuously fed ad-libitum their specific diets for 4 weeks. At the end of the experiment, all rats were sacrificed and the brain tissues were homogenized and examined for biochemical measurements of neurocellular oxidative stress indices [glutathione (GSH), Total Antioxidant Capacity (TAC), antioxidant enzymes and oxidized dichlorofluorescein (DCF)]. Al-administration caused inhibition of antioxidant enzymes and a significant decrease in GSH and TAC levels, meanwhile it positively increased cellular oxidized DCF level, as well as Al concentration in brain tissues. Feeding animals with MCE had completely offset the Al-induced oxidative stress and significantly restrict the Al accumulation in brain tissues of Al-administered rats. The results obtained suggest that MCE acted as a potent dietary antioxidant and protects against Al-mediated neurotoxicity, by abrogating neuronal oxidative stress.

Abstract
Genetic, nutrition, and environmental factors have each been implicated as sources of risk for autism. Oxidative stress, including low plasma levels of the antioxidant glutathione, has been reported by numerous autism studies, which can disrupt methylation-dependent epigenetic regulation of gene expression with neurodevelopmental consequences. We investigated the status of redox and methylation metabolites, as well as the level of protein homocysteinylation and hair mercury levels, in autistic and neurotypical control Omani children, who were previously shown to exhibit significant nutritional deficiencies in serum folate and vitamin B12. The serum level of glutathione in autistic subjects was significantly below control levels, while levels of homocysteine and S-adenosylhomocysteine were elevated, indicative of oxidative stress and decreased methionine synthase activity. Autistic males had lower glutathione and higher homocysteine levels than females, while homocysteinylation of serum proteins was increased in autistic males but not females. Mercury levels were markedly elevated in the hair of autistic subjects vs. control subjects, consistent with the importance of glutathione for its elimination. Thus, autism in Oman is associated with decreased antioxidant resources and decreased methylation capacity, in conjunction with elevated hair levels of mercury.

Abstract
Background Azoxymethane (AOM) is a potent carcinogenic agent commonly used to induce colon cancer in rats; the cytotoxicity of AOM is considered to mediate oxidative stress. This study investigated the chemopreventive effect of three natural extracts [pomegranate peel extract (PomPE), papaya peel extract (PapPE) and seaweed extract (SE)] against AOM-induced oxidative stress and carcinogenesis in rat colon. Methods Eighty Sprague–Dawley rats (aged 4 weeks) were randomly divided into 8 groups (10 rats/group). Control group was fed a basal diet; AOM-treated group was fed a basal diet and received AOM intraperitonial injections for two weeks at a dose of 15 mg/kg bodyweight, whereas the other six groups were received oral supplementation of PomPE, PapPE or SE, in the presence or absence of AOM injection. All animals were continuously fed ad-libitum until aged 16 weeks, then all rats were sacrificed and the colon tissues were examined microscopically for pathological changes and aberrant crypt foci (ACF) development, genotoxicity (induced micronuclei (MN) cells enumeration), and glutathione and lipid peroxidation. Results Our results showed that AOM-induced ACF development and pathological changes in the colonic mucosal tissues, increased bone marrow MN cells and oxidative stress (glutathione depletion, lipid peroxidation) in rat colonic cells. The concomitant treatment of AOM with PomPE, PapPE or SE significantly ameliorated the cytotoxic effects of AOM. Conclusions The results of this study provide in-vivo evidence that PomPE, PapPE and SE reduced the AOM-induced colon cancer in rats, through their potent anti-oxidant activities.

Abstract
Activated charcoal (AC) is a sorbent that has been shown to remove urinary toxins like urea and indoxyl sulfate. Here, the influence of AC on kidney function of rats with experimental chronic renal failure (CRF) is investigated. CRF was induced in rats by feeding adenine (0.75%) for four weeks. As an intervention, AC was added to the feed at concentrations of 10%, 15% or 20%. Adenine treatment impaired kidney function: it lowered creatinine clearance and increased plasma concentrations of creatinine, urea, neutrophil gelatinase-associated lipocalin and vanin-1. Furthermore, it raised plasma concentrations of the uremic toxins indoxyl sulfate, phosphate and uric acid. Renal morphology was severely damaged and histopathological markers of inflammation and fibrosis were especially increased. In renal homogenates, antioxidant indices, including superoxide dismutase and catalase activity, total antioxidant capacity and reduced glutathione were adversely affected. Most of these changes were significantly ameliorated by dietary administration of AC at a concentration of 20%, while effects induced by lower doses of dietary AC on adenine nephrotoxicity were not statistically significant. The results suggest that charcoal is a useful sorbent agent in dietary adenine-induced CRF in rats and that its usability as a nephroprotective agent in human kidney disease should be studied.

Abstract
OBJECTIVES This study aimed to investigate the lifestyle habits-physical activity (PA), eating habits (EH), and sleep duration (SD)-of Omani adolescents, and to examine gender differences in such variables. METHODS 802 Omani adolescents (442 females and 360 males), aged 15-18 years were randomly recruited. Anthropometric indices, PA level, and EH and SD were evaluated by the Arab Teenage Lifestyle questionnaire. A semi-quantitative food frequency questionnaire for dietary assessment was also administered. RESULTS The results showed that although the study subjects had a sedentary lifestyle (lack of PA, average of 6.7 hours sleep, and consumption of high calorie foods), they maintained a normal body mass (less than 25 Kg/m(2)). Males were more than twice as active as females. With respect to EH, there were few gender differences, except in dairy and meat consumption where 62.5% and 55.5% of males consumed more than 3 servings, respectively, compared to 18.78 % and 35.2% of females, respectively. In addition, waist/height ratio, height, reasons for being active, energy drinks, potato consumption, eating sweets, vigorous PA and breakfast EHs were statistically significant independent predictors for BMI, P <0.05 for both males and females. CONCLUSION This study revealed a high prevalence of sedentary behaviors and a low level of physical activity, especially among females. Unhealthy dietary habits were also widely found among both genders. There is an urgent need for more research as well as a national policy promoting active living and healthy eating and discouraging sedentary behaviour among Omani adolescents.

Abstract
A cross-sectional study was conducted to investigate whether caregiver's variations in socioeconomic status (SES) has direct bearing on challenges of nurturing children with autism spectrum disorder (ASD) in Oman. A cadre of caregivers (n = 150) from two types of SES (low-income and middle-high income) were compared based on four domains: (1) accessing and perception of remedial services, (2) utilization and perception of psychiatric services, (3) constraints for being a caregiver of children with ASD and (4) financial expenses of taking care of children with ASD. There is little indication that any particular SES fare well on these domains. Factors to mitigate such predicaments are therefore imperative in order to improve quality of life for caregivers among children with ASD.

Abstract
Particulate air pollution with particle diameters less than 2.5μm contribute to respiratory and extra-respiratory morbidity and mortality. We have recently reported the first in vivo experimental evidence that Diesel exhaust particles (DEP) in the lung aggravated the renal, pulmonary, and systemic effects of cisplatin (CP)-induced acute renal failure in rats. This in vitro study sought to determine whether and to what extent does DEP exposure exacerbate the effects of CP-induced oxidative stress in human embryonic kidney (HEK-293) cells, and to examine if these effects could be mitigated/prevented with curcumin (the yellow pigment isolated from turmeric). Cells viability, cysteine uptake and oxidative stress indices [glutathione (GSH), total antioxidant capacity (TAC), and the activities of antioxidant enzymes (catalase; glutathione peroxidase; superoxide dismutase)] were evaluated in all study groups. DEP aggravated the CP- induced HEK-293 cells toxicity, as evidenced by decreasing cell viability and by inducing oxidative stress (GSH depletion, TAC impairment, and antioxidant enzymes inhibition). DEP, but not CP, significantly reduced cysteine uptake. Curcumin prevented the observed DEP and CP-induced cellular insults. These findings suggest that DEP augmented the CP-induced toxicity in HEK-293 cells. Curcumin exhibited a strong potential for protection against DEP and CP-induced cytotoxicity.

Abstract
OBJECTIVE Adequate dietary intake is crucial for optimum training and performance of athletes. There is almost no available information related to dietary practices among Omani athletes, especially during the competition. This study aimed to assess the nutritional practices (nutritional knowledge, eating habits and daily nutrients intake) among Omani male handball athletes in Muscat city, Oman. METHODS This is a cross sectional study including 35 male handball athletes involved in serious training for no less than three years. Data collection was done through personal interviews using a study questionnaire which enlisted questions relating to socio-demographic information, anthropometric measurements and nutritional practices. All the study participants declared no intake of anabolic steroids. RESULTS The mean age of the study participants was 27 ± 3 years. Their anthropometric assessment revealed that their mean height was 166 ± 12 cm, mean weight was 75 ± 10 kg, and body mass index was 27 ± 3. Nutritional knowledge analysis revealed that 80% had no nutritional supervision by a nutritionist/dietitian. Their knowledge of nutritional requirements was only 23% correct for total energy intake, 63% for protein intake, 46% for carbohydrate intake, 11% for fat intake and 83% for water intake. Eating habits indicated that 55% had <3 meals/day, 51% had lunch as the principal meal, 51% always added extra salt to their food, 28% took protein supplements on a daily basis, and 51% used pre-competition glycogen load diet. However, none consumed vitamins or mineral supplements. The mean daily caloric intake was 3674 ± 265 kcal/day, which was roughly comprised of 596 ± 66 g carbohydrates, 147 ± 28 g of protein and 78 ± 20 g of total fat. CONCLUSION Professional nutritional supervision is needed in order to improve the nutritional knowledge and eating habits of Omani athletes, and therefore improve their athletic performance.

Abstract
OBJECTIVES Autism is a lifelong neurodevelopmental disorder of early childhood. Dietary supplementation of the ω-3 fatty acid (docosahexaenoic acid [DHA]) during prenatal and postnatal life is considered a protective dietary intervention strategy to minimize the risk for autism spectrum disorder (ASD). To our knowledge, no relevant studies have been conducted in the Middle East investigating the status of DHA among children with autism during early childhood. The aim of this study was to investigate the serum levels and dietary intake status of DHA among Omani children recently diagnosed with ASD. METHODS The present case-control study involved 80 Omani children (<5 y), 40 cases and 40 controls matched for age and sex. A semi-quantitative food frequency questionnaire was used to assess dietary intake of all the participants, while serum levels of DHA were measured using high-performance liquid chromatography. RESULTS Our results showed that children with ASD had lower dietary consumption of foodstuff containing DHA, as well as lower serum levels of DHA than controls. CONCLUSION The present finding from Oman supports the view of other studies that there are low serum levels of DHA among children with ASD.

Abstract
Toxic levels of heavy metals and low levels of essential minerals have been suggested to play a critical role in the pathogenesis of autism spectrum disorders (ASD). This study documents the levels of heavy metals and essential minerals in hair samples of children with ASD in Muscat, the urbanized capital of Oman, Muscat. The study included 27 children with ASD and 27 matched non-ASD controls. Parental interviews were held and dietary intake questionnaires completed in conjunction with the collection of hair samples. Analysis of heavy metals and essential minerals was carried out by inductively coupled plasma mass spectrometry. Chi-square analysis and non-parametric Fisher's exact tests were used to assess statistical significance. Children with ASD had significantly higher levels of all 11 analyzed heavy metals in their hair samples (P < 0.05), ranging from 150 to 365 % of control levels. ASD children also had significantly higher levels of essential minerals sulfur, sodium, magnesium, potassium, zinc, and iron, but lower levels of calcium and copper in their hair samples. This study corroborates data from previous studies in different parts of the world indicating the presence of elevated levels of heavy metals and selective depletion of essential minerals in the hair of children with ASD.

Abstract
BACKGROUND The anticancerdrug cisplatin (CP) causes nephrotoxicity through different mechanisms, including generation of free radicals. Ellagic acid (EA) is a polyphenolic antioxidant found in fruits and nuts. AIM This study aimed to investigate the ability of different doses of EA to ameliorate CP nephrotoxicity in rats. MATERIALS AND METHODS Animals were randomly divided into six groups and treated with saline; CP alone (6 mg/kg); two doses of EA, both alone (10 and 30 mg/kg) or with CP. RESULTS Treatment with CP alone reduced body weight, water intake, urine output, and renal total antioxidant and reduced glutathione (GSH) concentrations (p < 0.01). In addition, it increased relative kidney weight, plasma creatinine, and blood urea nitrogen (BUN) concentrations (p < 0.01). However, a dose of 30 mg/kg EA mitigated most of the CP-induced actions, but no effect was seen for the 10 mg/kg dose. Histopathologically, rats given CP+EA30 showed < 25% necrotic lesions in the renal cortical area compared with > 60% in rats treated with CP alone. Molecular analysis showed that clusterin (Clu) mRNA and protein were expressed in all treated groups, meanwhile kidney injury molecule-1 (Kim-1) mRNA and protein were only expressed in the CP and CP+EA treated rats. CONCLUSIONS EA (30 mg/kg) ameliorated most of the physiological, histological, and biochemical markers of CP nephrotoxicity. The molecular findings in this work did not completely tally with the conventional method used. The overexpression of the molecular markers may be related to the EA induced repair mechanism.

Abstract
Hydrogen peroxide is an oxidative stress agent that is associated with depletion of intracellular glutathione and inhibition of antioxidant enzymes in different cell lines. Consumption of antioxidant-rich foods reduces cellular oxidative stress and its related health problems. This study aimed to assess the antioxidant properties of mushroom, Agaricus bisporous cultivar extract, against hydrogen peroxide induced oxidative stress in cultured human hepatic (HepG2) and neuronal (SH-SY5Y) cells. In this study, hydrogen peroxide caused significant oxidative stress in HepG2 and SH-SY5Y cells as demonstrated by glutathione depletion, impairment of total antioxidant capacity and inhibition of antioxidant enzymes (glutathione peroxidase, catalase and superoxide dismutase). Agaricusbisporous extract ameliorated the observed hydrogen peroxide-induced oxidative cellular insult as indicated by restoring the activity of glutathione and the assayed antioxidant enzymes to control levels. The results suggest that mushroom extract as antioxidant properties and protects against the oxidative stress induced by hydrogen peroxide-in cultured human hepatic and neuronal cells.

Abstract
In a previous study, we demonstrated the ability of papaya epicarp extract (PEE) to protect against oxidative stress-induced insult in human SH-SY5Y neuronal cells in a mechanism that appeared to be by means of PEE potent antioxidant properties. To further understand this relationship, we examined the effect of PEE intervention on aluminum (Al)-induced cytotoxicity in SH-SY5Y cells. The results indicated that PEE was effective in protecting against Al-induced cell death in a dose-dependent manner. PEE restored the Al-induced inhibition of folate-dependent methionine synthase activity and the antioxidant enzymes (catalase, glutathione peroxidases and superoxide dismutase). PEE ameliorated the Al-induced impairment of intracellular glutathione and total antioxidant capacity. Together, these findings indicate that PEE supplementation can play a neuroprotective role in ameliorating the changes in redox status of SH-SY5Y cells exposed to Al, a well-known environmental toxin that is involved in the pathogenesis of neurodegenerative diseases and neurodevelopmental disorders.

Abstract
Autism spectrum disorder (ASD) is a neurodevelopmental disorder of early childhood, and an enumeration about its etiology and consequences is still limited. Oxidative stress-induced mechanisms are believed to be the major cause for ASD. In this study 19 autistic and 19 age-matched normal Omani children were recruited to analyze their degree of redox status and a prewritten consent was obtained. Blood was withdrawn from subjects in heparin-coated tube, and plasma was separated. Plasma oxidative stress indicators such as nitric oxide (NO), malondialdehyde (MDA), protein carbonyl, and lactate to pyruvate ratio were quantified using commercially available kits. A significant elevation was observed in the levels of NO, MDA, protein carbonyl, and lactate to pyruvate ratio in the plasma of Omani autistic children as compared to their age-matched controls. These oxidative stress markers are strongly associated with major cellular injury and manifest severe mitochondrial dysfunction in autistic pathology. Our results also suggest that oxidative stress might be involved in the pathogenesis of ASD, and these parameters could be considered as diagnostic markers to ensure the prevalence of ASD in Omani children. However, the oxidative stress-induced molecular mechanisms in ASD should be studied in detail.
