    Abstract Abstract Background Glucose-6-phosphate dehydrogenase (G6PD) deficiency, an X-linked disorder that is more common in males, is the most prevalent blood enzyme deficiency, affecting 5% of the population worldwide. Its prevalence in Saudi Arabia varies greatly from one region to another (4.7% to 12%), and no related data are available for the country’s Al-Qassim region. Methods This was a retrospective medical record-based study. Eligible patients were those who visited Dr. Sulaiman Al-Habib Hospital in Al-Qassim, Saudi Arabia, between June 2021 and November 2022, and underwent the test for G6PD enzyme deficiency. The study sample consisted of (n = 313) randomly selected Saudi patients. G6PD enzyme activity was evaluated using spectrophotometry. Results The prevalence of G6PD deficiency was 2.9%. The proportion of male patients (100%) was significantly higher than that of female patients. 88.9% of patients with G6PD deficiency experienced episodes of acute hemolysis and reported a history of favism, whereas 77.8% of the patients had a family history of favism. Conclusion The prevalence of G6PD deficiency was low in Al-Qassim region of Saudi Arabia.

    Abstract The current study was designed to explore the effect of fermented camel milk, plant sterols and their combination on the blood levels of sd-LDL and atherogenicity in rats fed on high-fat-cholesterol diets (HFC). Forty male Wistar rats were distributed into five groups: Normal control (NC), Positive control (PC, HFC), plant sterol (PS, HFC containing 1% (w/w) β-sitosterol:Stigmasterols; 9:1), FM (HFC containing 4% (w/w) lyophilized fermented camel milk), and PSFM (HFC containing 1% (w/w) plant sterols +4% (w/w) lyophilized fermented camel milk). Antioxidant activity showed that β-sitosterol had the highest radical scavenging activity, followed by fermented camel milk and stigmasterol (p < 0.05). Feeding rats on HFC for 8 weeks resulted in a significant (p < 0.05) increase in blood lipids of PC group compared with NC group. Administration of PS, FM, and PSFM resulted in a significant reduction in atherogenic index (50, 24.5, and 41.5 %, p < 0.05), and sd-LDL levels (73, 45, and 59%, p < 0.05), respectively. Only the FM group showed a significant reduction in triglycerides levels of rats. Administration of PS, FM and PSFM decreased serum MDA levels significantly by 58.7, 45.4, and 69% (p < 0.05), and increased total antioxidant capacity by 35.9, 84.8, and 38.3% (p < 0.05), respectively. This is the first report to the best of our knowledge that shows fermented camel milk enriched with plant sterol could reduce atherogenesis and cardiovascular diseases activity via inhibition of the status of small dense LDL and oxidative stress.

    Abstract Abstract Abnormal post-transcriptional modulations in inflammatory genes by microRNAs (miRNAs) play a crucial role in human disorders including arthritis. In this study, we determined the effect of hsa-miR-125b-5p on interleukin (IL)-1β induced inflammatory genes in human osteoarthritic (OA) chondrocytes. Bioinformatics algorithms showed 3′untranslated region (3′UTR) of TRAF6 mRNA (NM_004620.3) has perfectly matched ‘seed-sequence’ for hsa-miR-125b-5p. Treatment of cells with IL-1β up-regulates TRAF6 mRNA and down-regulates hsa-miR-125b-5p expression. This negative correlation between TRAF6 and hsa-miR-125b-5p was verified by transfection with miR-125b mimic (pre-miR-125b). Moreover, transfection with miR-125b mimic caused marked inhibition of IL-1β-induced phosphorylation of p38-MAPK, JNK-MAPKs and ERK-MAPKs and also suppressed the nuclear levels of NF-κBp50, NF-κBp65 and inhibited the activation of IκBα. Furthermore, transfected chondrocytes with miR-125b mimic in the presence of IL-1β also showed marked inhibition in the secretion of several proinflammatory cytokines, chemokines and growth factors including IL-6, IL-8, INF-γ, TGF-β1, IGFBP-1 and PGDF-BB. Importantly, this transfection also significantly inhibited IL-1β- induced MMP-13 expression/production. In short, this study concludes that hsa-miR-125b-5p acts as a negative co-regulator of inflammatory genes including MMP-13 via targeting TRAF6/MAPKs/NF-κB pathway in human OA chondrocytes.

    Abstract Background: The Coronavirus disease 2019 (COVID-19) has now been declared a global public health disaster with no currently available vaccine. This study was undertaken to analyse the effect of meteorological parameters such as temperature, humidity, and wind speed on the spread of ongoing COVID-19 in Saudi Arabia. Methods: The COVID-19 dashboard for five major cities of Saudi Arabia - Riyadh, Makah, Jeddah, Medina and Dammam was used for data collection. The data on weather were collected from the Weather Underground Company (IBM business GA, USA, 2020). The data were analysed by Spearman's rank correlations using JASP statistical software in two main sections. In the first section the data on COVID-19 from cities were combined to analyse the overall picture of COVID-19 and in the second section, different meteorological parameters such as temperature, humidity and wind speed were analysed. Results: Novel data revealed interesting facts on the spreading of COVID-19 in Saudi Arabia, the data showed that the number of COVID-19 positive cases increases due to the decrease of temperature or humidity, whereas an average decrease in the wind speed was also found to be associated with an elevation of the number of positive cases. Conclusions: This study determined the impact meteorological factors on the infectivity rate of COVID-19. An inverse association was found between the meteorological parameters with the spreading of COIVD-19. Therefore, this study directs the health authorities to implement specific measures against the spreading of this global pandemic based on weather patterns.

    Abstract Pomegranate, scientifically known as Punica granatum, has been a traditional medicinal remedy since ancient times. Research findings have shown that using pomegranate extracts can positively affect a variety of signaling pathways, including those involved in angiogenesis, inflammation, hyperproliferation, cellular transformation, the beginning stages of tumorigenesis, and lastly, a reduction in the final stages of metastasis and tumorigenesis. This is due to the fact that pomegranate extracts are rich in polyphenols, which are known to inhibit the activity of certain signaling pathways. In the United States, cancer is the second biggest cause of death after heart disease. The number of fatalities caused by cancer in the United States escalates yearly. Altering one's diet, getting involved in regular physical activity, and sustaining a healthy body weight are three easy steps an individual may follow to lower their cancer risk. Simply garnishing one's diet with vegetables and fruits has the potential to avert at least 20% of all cancer diagnoses and around 200,000 deaths caused by cancer each year. Vegetables, fruits, and other dietary constituents, such as minerals and phytochemicals, are currently being researched for their potential to prevent cancer. It is being done because they are safe, have minimal toxicity, possess antioxidant properties, and are universally accepted as dietary supplements. Ancient civilizations used the fruit of pomegranate (Punica granatum L.) to prevent and cure a number of diseases. The anti-tumorigenic, anti-inflammatory and anti-proliferative qualities of pomegranate have been shown in studies with the fruit, juice, extract, and oil of the pomegranate. Pomegranate has the capacity to affect several signaling pathways, which implies that it may have the potential to be employed not only as a chemopreventive agent but also as a chemotherapeutic drug. This article elaborates on some recent preclinical and clinical research which shows that pomegranate seems to have a role in the ...

    Abstract ABSTRACTThis study was carried out to evaluate the effects of dietary concentrate: forage (C: F) ratio on fat deposition, fatty acid composition, oxidative stability and mRNA expression levels of sirtuins genes associated with adipose tissue metabolism of subcutaneous fat in Black Tibetan sheep. Three diets with different C: F (HC: 70:30, IC:50:50 and LC: 30:70) were fed to fifteen weaned male lambs (2-month-old, 10.05 ± 0.96 Kg). The experiment lasted for 120 d. Five lambs from each group were randomly selected and slaughtered at the end of the experiment. The subcutaneous fat thicknesses increased with increasing concentrate level (P < 0.05). The concentration of polyunsaturated fatty acid (PUFA), C15:1 and C18:2n decreased by feeding the HC diet (P < 0.05). Both glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) activities significantly increased as dietary concentration levels decreased (P < 0.05). Additionally, SIRT1 and SIRT2 expression level was downregulated (P < 0.05) with increasing concentration supplementation (P < 0.05 and P < 0.05, respectively). In conclusion, the addition of 70% concentration supplementation is not recommended in Black Tibetan sheep, considering that no benefits were observed for nutrient utilization, oxidative stability or economic returns, while the supplementation of C: F at 50:50 proved to be suitable for finishing lambs.

    Abstract The current approach described the synthesis of a new series of indolylpyrrole derivatives through multicomponent reaction of α-cyano chalcones, appropriate aldehydes, and ammonium acetate in refluxed acetic acid. The chemical structures of the designed compounds were confirmed with spectroscopic data and elemental analysis and then tested for their in vitro cytotoxic activity by SRB assay method towards three cell lines involving human Prostate adenocarcinoma; metastatic cells (PC-3), human ovary adenocarcinoma (SKOV3) and human dukes' type B, colorectal adenocarcinoma (LS 174 T). Most significant activity provided with compounds 5c, 5h and, 5j against prostate cancer cells (PC-3) with IC50s of 3.30 ± 0.20, 3.60 ± 0.10, and 3.60 ± 0.90 µg/ml, respectively. In human ovarian carcinoma (SKOV3), the compounds 5a, and 5i have stronger cytotoxicity with IC50s of 1.20 ± 0.04, 1.90 ± 0.50 µg/ml, respectively than the standard doxorubicin (IC50 = 2.20 ± 0.02 µg/ml). On the other hand, only compound 5a has the ability to diminish the viability of LS174T cells in an active manner with IC50 2.80 ± 0.10 µg/ml. Consequently, this effort offers groundwork for additional examination of nominated indolylpyrroles as antiproliferative agents.

    Abstract ABSTRACTResveratrol (RVT) is well known for its chemo-preventive and therapeutic attributes against the various kinds of cancers such as breast, prostate, pancreatic, oral, brain, lung and liver. It has been found to inhibit glioblastoma cell growth, declining uPAR and its mediator ERK1/2, inhibiting the cell lines (EC-9706) growth and ADAM9 expression, up-regulating the lncRNAs and PPARγ, inhibition of MTA1 to modulate oncogenic miR-34a, miR-22 and miR-17, enhance the E-cadherin expression and decreased the expressions of Twist1 and vimentin, inhibiting ADAM9 expression, downregulation of ATP2A2 and ATP2A3 genes expressions in different breast cell lines, reduction in IL-6 and COX-2 expression, inhibition of Tax activity of LTR and HTLV-1 in SIRT1 deacetylase, suppression of epithelial-to-mesenchymal transition (EMT) and eEF1A expression and fracas interactions between TEAD and YAP and activation of Hippo/YAP signalling. Consequently, it can be suggested that RVT is a promising agent for treating aforementioned cancers due to its curing characteristics.
