The prevalence of hypertension in Nigeria is 28.9%. In Nigeria, analytical studies to determine risk factors and potential biomarkers of hypertension are lacking. This study was conducted to determine lifestyle, anthropometric, socio-demographic, and biochemical risk factors associated with hypertension in Lagos, Nigeria. Method This case–control study was conducted among 410 participants, aged 18–65 years. A well-structured questionnaire was used to collect data from cases and controls. Anthropometric and blood pressure measurements were taken. Blood samples were also collected for biochemical analysis. Logistic regression analysis was used to determine risk factors associated with hypertension. Data obtained were analyzed using SPSS version 25.0. P-value less than 0.05 was considered statistically significant. Result In total, 205 hypertensive cases and 205 normotensive controls were recruited. The mean ± SD age of the participants was 39.25 ± 11.49 years. Overall, 180 (44%) of participants were female.

Likewise, chromosomal instability, describes an oxidative DNA damage that can be accelerated by chronic hyperglycemia. This work investigates the extent and contribution of diabetes oxidation/stress on protein carbonylation and chromosomal instability among 120 type 2 diabetics (60 with vascular complications and 60 without any vascular complications) and 50 apparently healthy control subjects. Anthropometric data and fasting venous blood specimen was collected from each participant for glyceamic control, antioxidants, protein oxidation, oxidative DNA damage parameters and chromosomal aberration assay using standard methods. Results: Diabetics without vascular complications shows a significant (p = 0.0000) difference in all measured parameters except 8-OHdG (p = 0.0764) as compared to control subjects. However, diabetics with vascular complications show significant (p = 0.0000) difference of all measured parameters than those without vascular complications. Conclusion: Our study findings indicate an increased formation of protein carbonyl contents, and chromosomal aberration in diabetics especially among those with vascular complications, likewise, diabetes with vascular complications is associated with increased DM disease activity. Thus, protein oxidative biomarker can serve as a therapeutic tool in the management of diabetes cases while increased chromosomal aberration may indicate an increased risk for cancer among diabetics.","PeriodicalId":7611,"journal":{"name":"Alexandria Journal of Medicine","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20905068.2021.1935123","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46070716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

FA that can be used in many industries, medical and anatomical facilities, mainly cadaver-based gross anatomy laboratories, represent a risk to occupational health of professionals and students. The majority of FA exposures occur through inhalation, dermal, and eye contact. FA-induced effects are attributed to site-specific and dose-dependent health impairments in many organs and organ systems. Much progress has been reported on FA-induced health impairments in respiratory tract, but a comprehensive study in different organ systems and the reverse effects of some novel antioxidants is still lacking. This review explores the cytotoxic effects of FA and its role as key signaling molecule, site specific and or dose dependent effects of FA in nasal cavity, carcinogenic effects of FA exposure in nasopharynx, effects of FA in lung macrophage functions and development of pulmonary fibrosis, dose dependent reproductive and genetic effects of FA, neurotoxic effects of FA and potential risk of FA in some beauty salons and cosmetic products. In addition, this study shows the counteracting beneficial role of melatonin, Nigella sativa, rose oils, caffeic acid phenethyl ester (CAPE), vitamin E, and proanthocyanidins (PAs) against FA induced tissue damage.Methods: A comprehensive literature search highlighting the health impairments of FA and counteracting beneficial effects of promising antioxidants was conducted using PubMed, Google Scholar, and Medline Cochrane, to assemble relevant publications from open access international journals published only in English.Results: The search generated 411 articles of which 70 full research articles fulfilled the inclusion criteria and included in the review. The results of this study confirmed relentless toxic effects of FA exposure on various organs of human and other animals. Multiple findings also stated the efficacy of promising antioxidants against FA-induced tissue damage in animal models.Conclusion: Occupational exposure to FA is most likely due to inattention towards its side effects and lack of appropriate air filtering equipment or unmonitored concentration of FA in the working air. Therefore, re-evaluating the concentration of FA, proper ventilation, and assessment of working practices is highly recommended. Proper monitoring is also needed to improve compliance and protection of FA-based reproductive complications in females. Despite complete prevention is not viable, exposed personnel must be aware of FA-induced health effects and require assessing risks and acquiring practical measures in their working environment.","PeriodicalId":7611,"journal":{"name":"Alexandria Journal of Medicine","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20905068.2021.1926172","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44075787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Worries have increased concerning the harmful effects of their radio-frequency electromagnetic radiation. Liver X receptors (LXRs) are ligand-dependent transcription factors that have important roles in lipid metabolism and inflammation, plus several recently emerging roles. Whether it is useful to overcome the hazardous effects of cell phone radiation needs to be clarified. So, this study aimed to investigate the effect of LXRs activation on testicular changes in rats exposed to electromagnetic radiation. Methods: Thirty adult male Wistar rats were subdivided into control group, experimental group: exposed to cell phone electromagnetic radiation, and treated group: as experimental group and received LXRs agonist T0901317. Serum testosterone (T), Follicle-Stimulating Hormone (FSH), and Luteinizing Hormone (LH), testicular tissue malondialdehyde (MDA) and superoxide dismutase (SOD), and gene expressions of inflammatory and apoptotic markers were assessed. Seminal analysis and testicular histological examination were performed. Results: LXRs activation in rats exposed to cell phone radiation improved the decreased testicular and gonadotrophic hormones, semen quality parameters, tissue SOD, and anti-apoptotic gene expression as well as the elevated tissue MDA, apoptotic and inflammatory gene expressions, and the testicular histological changes induced by exposure to electromagnetic radiation. Conclusion: Exposure to cell phone radiation leads to harmful effects on spermatogenesis and LXRs activation could improve these effects via antioxidant, anti-inflammatory properties in addition to its endocrinal action.","PeriodicalId":7611,"journal":{"name":"Alexandria Journal of Medicine","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20905068.2021.1884333","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49281075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Prospective study for 40 patients presented to Alexandria Main University hospital with unilateral cleft lip deformity between March 2019 and October 2020. Twenty patients with unilateral cleft lip deformity were repaired by Fisher anatomical subunit approximation technique, while the other twenty were repaired by Millard rotational-advancement technique. The postoperative photographs of the patients were captured and processed in computer photogrammetry software through which anthropometric parameters including (lip height, lip width, vermilion height, and alar base width) were compared between the normal side and the repaired side. In this software, each anthropometric parameter length on the normal side is taken as a control with a fixed value of (1) then the same parameter on the repaired side was measured as a ratio of this value to avoid bias. Comparison between both groups for assessment of the quality of cleft lip repair was also done based on Steffensen grading criteria. Results: Comparison between both techniques in unilateral cleft lip repair showed that there was no significant difference between them in the anthropometric measurements. While the comparison between the two groups using Steffensen grading criteria showed that Fisher’s technique surpassed Millard’s technique.

Among dialysis patients, conflicting data exist concerning the relationship between hepatitis C virus (HCV) infection and OS. We studied the relationship between 25Vit.D level, HCV infection, and plasma 8 iso-prostaglandin F2 α (8-ISO-PGF2α) as an OS marker in an Egyptian hemodialysis (HD) cohort. Methods One hundred and twenty ESRD patients on HD were initially recruited to the study but only 88 patients have met the inclusion and none of the exclusion criteria. Midweek predialysis session blood samples were collected for the measurement of 25(OH) Vit.D, plasma 8-ISO-PGF2α, high sensitivity C – reactive protein (hs-CRP), and intact parathyroid hormone (intact PTH). Patients were stratified into two groups according to the presence or absence of serum antibodies against HCV and their plasma 8-ISO-PGF2α were compared.
