    Four cultures of Sporulating yeast strains: Kluyveromyces bulgaricusSG 120, Saccharomyces bayanusPS8, Saccharomyces uvarum PS22and Saccharomyces sp. A7. The strains were isolated from spoiled canned apple, pasteurized beer and canned apple pieces respectively. The 4cultures of yeast was used. They were tested for their ability to produce ascospores. Techniques for inducing sporulation were used. A 48 hrs. culture suspension for each yeast was prepared. Adequate 1ml was inoculated into screw capped disposable test tubes containing 10 mls. Y M broth consisting of tested levels of 250, 500 1000 ppm of Sorbic, Propionic and Benzoic acids. Culture growth was measured each hour using a Nephelometer. The results showed that Sorbic cid inhibited the growth of yeast SG 120 at the three levels tested. It delayed the growth of strains PS22, PS 8 and A7 at higher levels of 500 and 1000 ppm. Both propionic and benzoic acid failed to inhibit the growth of the four strains SG120, PS8, PS22 and A7 at the three levels

    Purpose: To study the possible mitigating effect of erdosteine (ERD) against methotrexate (MTX)-induced liver toxicity.Methods: Male albino Sprague-Dawley rats were randomly assigned to four groups of 8 rats each, viz, vehicle control, MTX (20 mg/kg i.p.), MTX (20 mg/kg i.p.) + ERD (300 mg/kg) and ERD (300 mg/kg) groups. Serum levels of alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were determined by enzymatic colorimetric commercial kits while Hepatic tissue content of malondialdehyde (MDA), reduced glutathione (GSH), SOD and catalase (CAT) were also evaluated. In addition, measurement of the inflammatory cytokine, TNF-α, as well as histopathological  examination and histochemical assessment were carried out.Results: The results indicate that, compared to the control group, MTX group showed a remarkable elevation in oxidative stress as indicated by significantly lower levels of SOD, CAT and reduced glutathione, and increased tissue malondialdehyde (p < 0.05). MTX group exhibited significantly higher blood activities of ALT, AST and TNF-α, reflective of hepatocyte damage and inflammation (p < 0.05). In MTX group, significant hepatic degenerative changes were detected on histological examination, while marked apoptotic alternations were observed following  immunohistochemical analysis of caspase-3 expression, when compared to control group. However, administration of ERD to rats ameliorated thechanges in these parameters (p < 0.05).Conclusion: Treatment with ERD in rats produced alleviation in hepatic oxidative stress, apoptosis, inflammation, and histological damage, when compared to MTX group. This study is the first to demonstrate the potentially protective effect of ERD-pretreatment against hepatotoxicity associated with MTX.

Background A global epidemic of obesity has been documented, particularly among African countries. While central obesity and overweight have been reported for many countries, very limited information exists about the prevalence of these health problems in Sudan, and these data are nonexistent for Eastern Sudan. The present study aimed to determine the prevalence of obesity and central obesity, as well as the factors associated with both, among adults in Gadarif, Eastern Sudan. Methods A cross-sectional study was conducted in Gadarif, Eastern Sudan, during the period of January through May 2018. Sociodemographic and health characteristics data were collected through a questionnaire. Body mass index (BMI) and waist circumference (WC) were measured using the standard methods. Both descriptive and inferential statics were applied to analyze the data. Results A total of 594 adults participated in the study; 70.4% of them were female. The mean (standard deviation) age was 44.98 (16.64) years. Of the 594 enrolled participants, 33.7%, 7.4%, 26.8%, and 32.2% were normal weight, underweight, overweight, and obese, respectively. The prevalence of central obesity was (67.8%). Approximately, one-third of the participants (29.29%) were obese and had central obesity. In the multinomial regression, being married was the main risk factor associated with overweight, and older age, female sex, being married and hypertension were significantly associated with obesity. In the binary regression, the main risk factors associated with central obesity were female sex and being married. Conclusion The prevalence rates of both obesity and central obesity among the study participants were high. Older age and hypertension were only associated with obesity. Obesity and central obesity were significantly associated with female sex and being married. This study provided valuable baseline information to develop appropriate strategies for the prevention and control of obesity in Eastern Sudan

    Abstract Objective: Optimum management of patient needs is the most important step for the restoration of form and function. Maxillomandibular fixation is one of the treatment modalities used very frequently in maxillofacial surgery. This study aims to determine the mean change in weight in patients undergoing Maxillomandibular Fixation. Methods: This observational cross-sectional study was conducted at the Department of Oral and Maxillofacial Surgery Foundation University Medical College from 27th April 2018 to 22nd January 2019. This study included patients male and female, who presented with maxillofacial trauma, orthognathic surgery and procedures in which MMF ( Maxillomandibular fixation ) was indicated were included in this study. Pre-operative weight was measured in kilograms with an analogue weight machine and designated as W1. Patients were advised to a liquid diet and kept on follow-up. After four weeks of MMF again weight of the patient was measured and designated as W2. Follow-up was done through the patient's contact number. Results: In this study, the mean weight of patients preoperatively was 59.46±12.23 Kg. The postoperative mean weight of patients was 57.81±11.58 Kg. A decrease of 1.65 Kg was seen in the patient’s weight postoperatively.  No significant difference was seen for weight change in patients postoperatively with age, gender, educational status, occupational status, socioeconomic status and an indication of MMF. Conclusion: Results of this study showed weight loss in patients who underwent maxillomandibular fixation. This factor should be considered during the perioperative period to prevent postoperative complications, postoperative weight loss, and malnutrition of patients undergoing maxillomandibular surgery and reflect the need for guidance on diet postoperatively, mainly directed to frequency of feeding and high protein liquid diet and nutritional supplements.

    Background: Anti-Vascular Endothelial Growth Factor (Anti-VEGF) therapy serves to decrease central retinal thickness in eyes affected with diabetic macular edema (DME). The Retinal Nerve Fiber Layer (RNFL) forms the basis of the optic nerve. Objectives: Our study is concerned with studying the effects of Anti-VEGF injections in patients with DME on RNFL thickness. Patients and methods: This was a prospective cohort interventional study conducted at South Valley University Hospital, Ophthalmology department outpatient clinic. It included 50 diabetic patients with diabetic macular edema whose RNFL thickness was measured before the anti-VEGF injections and again after the completion of the three injections treatment course using spectral domain optical coherence tomography (SD-OCT). Results: This study included 50 eyes from 50 patients. 35 (70%) of them were females and 15 (30%) of them were males. 26 patients (52%) had their right eye injected, and 24 patient (48%) had their left eye injected. The superior quadrant of the RNFL showed a mean increase of 1.2 microns (SD = 38.4, 95% Confidence Interval CI = -9.7:12.1, p value = 0.829). The inferior quadrant showed a mean increase of 7.5 microns (SD = 35.6, 95% CI = -2.6:17.6, p value = 0.144). The nasal quadrant showed a mean increase of 8.3 microns (SD = 23, 95% CI = 1.8:14.9, p value = 0.014). The temporal quadrant showed a mean increase of 4.1 microns (SD = 33.2, 95% CI = -5.3:13.6, p value = 0.386). Conclusion: There is no statistically significant correlation between intra-vitreal injections of anti-VEGF and the RNFL thickness

    Background: The presence of defects in native umbilical in adults and its use as laparoscopic first entry site is poorly documented. It would likely be a safer method than the Veress needle and direct trocar insertion. This work aimed to report the prevalence and size of native umbilical defects, and their relationship with gender, age and body mass index. Methods: In 160 consecutive laparoscopic operations, a trans-umbilical incision was made and a defect at its base was looked for. When found, the defect was measured and used as the first port entry site. Relationships of presence of native defects and their sizes in relation to gender, age and BMI were analyzed. Results: The prevalence of a native defect in this series was 90%. Its presence had no relation with gender, age or BMI. Its size, however, positively correlated with age and BMI. No complications were related to the defect’s use for first laparoscopic entry site. Conclusion: A native umbilical defect is present in 90% of adults. Whenever present, it is recommended for use as the first port entry site by an open technique. This method is simple and safe and avoids unnecessarily inducing another defect.
