RESUMO

<b>Background and Objective:</b> Ras cheese is one of the important dairy products that are consumed in great quantities. But this cheese is vulnerable to the growth of fungi during ripening and selling until consumption. Therefore, research aimed to detect fungi contaminating Ras cheese and try to resist them. <b>Materials and Methods:</b> The effect of various concentrations (0.25, 0.5, 1, 2 and 3%) of essential oils emulsions of clove (<i>Syzygium aromaticum</i>), thyme (<i>Thymus vulgaris</i>) and peppermint (<i>Mentha piperita</i>) severally on the mycelial growth of the isolated fungi as compared to the control sample was tested <i>in vitro.</i> <b>Results:</b> The results indicated that many fungal species belonging to the genera <i>Aspergillus</i>, <i>Mucor</i>, <i>Eurotium</i> and <i>Mortierella</i> were isolated from the infected Ras cheese. Ochratoxin A was found in two samples whereas recorded the highest level in sample number 1 (2.1 µg kg<sup>1</sup>). Aflatoxin M1 was found in few levels ranged between 0.012 and 0.360 µg kg<sup>1</sup>in cheese samples, while aflatoxin B1 and B2 weren't detected in all samples. Clove essential oil emulsion completely inhibited the growth of all tested fungi at the concentration of 0.5%, followed by thyme essential oil emulsion which inhibited the fungal growth of all fungi at the concentration of 1%, while peppermint essential oil emulsion was less effective. <b>Conclusion:</b> The research recommends that clove and thyme essential oils emulsions can be used to resist the fungi of Ras cheese. Also, suggests that more research could be done on these essential oils emulsions to produce safe foods free of fungi.

RESUMO

BACKGROUND: School feeding program (SFP) increases access to education and to better health. This study aims to evaluate the effects of SFP on physical growth, cognitive development, psychosocial behavior, and learning achievement of school children. METHODS: A quasi-experimental study was conducted. The intervention group included 903 pupils in the fifth grade receiving the school meal, while the control group included 886 pupils, matched for age and sex, without meal. The meal consisted of a pie made of flour fortified with vitamins A, B6, B12, C, thiamin, riboflavin, niacin, folate, calcium, iron, zinc, and phosphorus. Socioeconomic position, nutritional status, and dietary behavior were evaluated. Neuropsychological tests were done. Psychosocial behavior was rated and educational achievement was recorded. Post hoc and independent sample t tests were used to detect the association of the studied parameters with the intake of school snack. RESULTS: Children who took the meal had better scores on visual memory, auditory vigilance tests (9.71 ± 2.80 vs. 7.45 ± 3.25; 25.02 ± 3.36 vs. 10.82 ± 8.92, respectively, P < 0.001), the afternoon attention and working memory test (8.20 ± 2.21vs. 7.75 ± 3.05) (P < 0.001), but less score of externalizing behavior (P < 0.001) than the control group. No significant changes of children's nutritional status were detected between the two groups. School meal was the main predictor of visual memory and auditory vigilance (P < 0.001), and was the strongest predictor of academic achievements when combined with family size and meals' frequency (P < 0.001). CONCLUSION: School meal improves academic achievements of school children.

RESUMO

Varicocele is the most common abnormality identified in men being evaluated for subfertility. In this comprehensive review of the pathophysiology of varicocele, we will shed light on novel pathophysiological findings and their clinical implications that may direct future researches; we will shed light on the impact of transient scrotal hyperthermia and the roles of inflammation and differential protein expression and androgen expression in spermatozoa on inducing pathophysiological findings. Furthermore, we will clarify the linked processes contributing to the pathophysiology of varicocele and the impact of genetics on the induction of these processes. Spermatogenesis is a temperature-sensitive process, and heat stress of varicocele is considered the most plausible cause of impaired spermatogenesis. The three processes associated with the presence of varicocele - heat stress, excess reactive oxygen species, and increased apoptosis - appear to be linked; heat stress is associated with increased levels of reactive oxygen species and oxidative stress, which can induce apoptosis. The genetic role should not be overlooked as a contributing factor in the induction of heat stress, excess reactive oxygen species/oxidative stress, and apoptosis; this is evidenced by the association of varicocele with decreased expression of heat-shock proteins, higher polymorphism of glutathione S transferase and nitric oxide synthase genes, and increased BAX and decreased BCL2 genes and proteins. In this article, we will highlight the need of application of novel diagnostic techniques that can provide a precise pathophysiological diagnosis to guide potential specific innovative therapies. Innovative therapies can counteract the varicocele-induced stasis, suppress the degenerative effects of testicular hyperthermia, reduce the varicocele-induced apoptosis, and target the elevated-neutrophil products aiming at abrogating the testicular damage caused by the induced varicocele in rats/mice. In conclusion, on the basis of the novel scientific research, it may be possible to formulate new treatments and achieve the appropriate selection of patients who can benefit from these treatments.

RESUMO

The aim of the present study was to assess female sexual function in an obese group (250 women) and to compare it with a control group (100 women), among 25-35-year-old uncircumcised Egyptian women, using female sexual function index (FSFI) score. FSFI total score of ⩽ 26.55 was considered diagnostic of Female Sexual Dysfunction (FSD). The percentage of FSD in the obese group was 73.6% while it was 71% in the control group, which was statistically insignificant (P > 0.05). The difference between both groups regarding the total (FSFI) score was insignificant (P > 0.05), but arousal and satisfaction domains scores were significantly lower in the obese group. In the obese group, a strong negative correlation between body mass index and arousal, orgasm and the total FSFI score was found. Women with excessive obesity had the lowest total FSFI score. In the obese group, college graduates had the highest total scores and all domain scores of FSFI followed by high school graduates while the least educated women had the lowest scores and when these subgroups were compared, significant differences were found among them. We conclude that in uncircumcised 25-35-year-old Egyptian women, obesity is not a major detrimental factor for FSD, but it may affect some sexual domains such as arousal and satisfaction, although excessive obesity is associated with FSD. Also, educational and cultural factors may have an impact on perception of sex and pleasure.
