Objective: To investigate the true incidence of Bacillus cereus(B. cereus) in food and children diarrhea cases. Methods: A total of 110 samples of various dairy products such as raw milk, long life pasteurized milk, yoghurt and infant powdered milk formulas, raw rice, and feces were examined for the presence of B. cereus by selective plating on mannitol-egg-yolk-polymyxin agar. Confirmation of B. cereus was carried out by biochemical tests and PCR. Identification of non-B. cereus isolates was carried out by 16 S r DNA sequencing. Antimicrobial susceptibility was done by disk diffusion ***: Overall 35 samples(31.8%, n = 110) yielded Bacillus-like growth. Of which 19 samples(54.28%) were positive for B. cereus. All isolates were positive for enterotoxin production. No psychrotolerant B. cereus strains were detected in all samples. All B. cereus isolates were resistant to penicillin G, but susceptible to vancomycin, erythromycin and clindamycin. Conclusions: The results of this study confirm the importance of including B. cereus in disease control and prevention programs, as well as in routine clinical and food quality control laboratories in both Saudi Arabia and Egypt.

This paper represents a review of the recent researches that investigate the behavior of the gas turbulent flow laden with solid particles. The significant parameters that influence the interactions between the both phases, such as particle size, loading ratio and the gas velocity, have been extensively reviewed. Those parameters are presented in dimensionless numbers in which the applicability of studying its effect in terms of all circumstances of the gas turbulent channel flow at different condition is possible. The represented results show that the turbulence degree is proportional to the particle size. It was found that at the most flow conditions even at low mass ratio, the particle shape, density and size significantly alter the turbulence characteristics. However, the results demonstrate that the particle Reynolds number is a vital sign: the turbulence field becomes weaker if particle Reynolds number is lower than the critical limit and vies verse. The gas velocity has a strong effect on the particles settling along the channel flow and as a result, the pressure drop will be affected.

Black bean aphid, Aphis fabae (Homoptera;Aphididae) is a serious pest causing crop loss. Plant-aphid interaction is a dynamic system subjected to continual variation and changes. Host plants induce various biochemical and physical defense mechanisms due to aphid feeding. Aphids can overcome plant defenses by enzymatic adaptations and sequestering secondary metabolites produced by the plant within their bodies as a defense against their enemies. Many strategies were developed and evolved by aphids in order to overcome plant defense barriers which allowed them to feed, grow and reproduce on their host plants. This study aimed to aid in better understanding of the effect of altering host plant on specialist and generalist aphid *** influence of plant defense on population development of Aphis fabae was also investigated. Analyses for insect enzymes were also demonstrated in addition to further biochemical studies on host plant defences. Generalists showed different ecological and enzymatic adaptations towards host plants than specialist Aphis fabae. The results were fully discussed in details.

Introduction: This study aimed to evaluate, discuss and illustrate the role of fetoscopy diagnostically and therapeutically. Material and Methods: This study was conducted in private center in under the supervision of the professors of Azhar University, Egypt from Dec-2012 to Mar-2017. Women with confirmed fetal congenital malformations, and willing to do fetoscopy were recruited. Fetoscopy was attempted in all cases to treat the underlying fetal conditions. Follow up was made until delivery. Results: Twenty patients with 22 fetuses were included in this study with different congenital anomalies. Therapeutic drainage or coagulation was made in all cases. In cases of lower urinary tract obstruction, fetoscopy confirmed pre-suspected urethral atresia and changed the diagnosis from complete PUV to urethral atresia in some cases. The procedure succeeded in all cases. However, the on-going success rate was 17 (77.3%) of fetuses. The overall number of live birth was 11 fetuses (50%). Overall, 15 (75%) of the 20 patients experienced some complication withpreterm labor the most prevalent 15 (75%). Conclusion: Fetoscopy can diagnose and differentiate between posterior urethral valve (PUV) and atresia, and manage well-selected cases of twin to twin transfusion syndrome (TTTS), and have a reasonable survival rate in lower urinary tract obstruction (LUTO).

Aim: We attempted to illustrate our experience of fetoscopic therapy in a tertial institute, whereby to highlight the present Egyptian situation regarding this issue. We described fetoscopic therapy undergone at Al-Hussein Hospital, Al-Azhar University, Cairo, Egypt, from Dec-2012 to Sep-2019. Presentation of cases: Sixteen women with 17 fetuses were included in the analysis of this study with a mean age of 25.31 ± 6.15 years;four with positive marriage to a near relevant, and eight were primigravida. The fetus of twelve women had lower urinary tract obstruction (LUTO), two fetal anemia, one hydrothorax, and one twin-to-twin transfusion syndrome (TTTS). The mean time for fetoscopy was gestational week 24.13 ± 3.77. We did therapeutic drainage to amniotic fluid in hydrothorax and LUTO, therapeutic septostomy to the TTTS case, and blood transfusion in cases of fetal anemia. During the operation, the procedure succeeded in 14 out of 16 women. Overall, nine of the 16 women experienced some complications;five with rupture of membranes, four with preterm labor, and three with intrauterine fetal death (IUFD). Conclusion: Fetoscopy can manage LUTO and well-selected cases of TTTS, hydrothorax, and fetal anemia. The procedure is promising. Fetoscopic therapy has just begun in Egypt, and this report may contribute to the future advance of fetoscopic therapy in Egypt.

AIM: To evaluate the efficacy and safety of botulinum toxin type A(BTX-A) in the management of patients with anismus. METHODS: An organized search of published literature was conducted using electronic databases including: Pub Med/MEDLINE, and Cochrane Central Register of Control ed Trials, also an internet-based search using "Google Scholar" service was conducted. Both comparative and observational studies were included. We excluded irrelevant articles, editorials, case reports, reviews, and meta-analyses. The studies that followed the patients less than 6 mo were excluded. Variables collected were demographic data of the patients, technique of BTX-A injection and number of sessions, short-term and longterm clinical improvement, post-injection changes in electromyography(EMG), defecography, manometry, and balloon expulsion test, and complications recorded after BTX-A ***: Seven studies comprising 189 patients were included in the review. The median age of the patients was 41.2 years and female-to-male ratio was 1.3:1. The median dose of BTX-A injected per procedure was 100 IU(range, 20-100 IU). Lateral injection was done in five trails and combined lateral and posterior injections in two trials. Three studies used endorectal ultrasonographyguided technique, one study used EMG-guided technique,whereas the remaining three studies used manual palpation with the index finger. The median percentage of patients who reported initial improvement of symptoms was 77.4%(range 37.5%-86.7%), this percentage declined to a median of 46%(range 25%-100%) at 4 mo after injection of BTX-A. Rates of improvement evaluated by balloon expulsion test, EMG, and defecography ranged between(37.5%-80%),(54%-86.7%), and(25%-86.6%), respectively. Fourteen(7.4%) patients developed complications after injection of BTX-A. Complication rates across the studies ranged from 0% to 22.6%. CONCLUSION: Initial satisfactory improvement of symptoms after BTX-A injection remarkably deteriorate
