ABSTRACT
In this research, some plant seeds powder was evaluated to find their potential effect to rule diseases of food poisoning. Antimicrobial effect of five plant seeds was examined contra Bacillus cereus, Staphylococcus aureus, Escherichia coli, Klebsiella. pneumonia and Candida albicans by using well diffusion method. Antimicrobial activity studies revealed high potential activity of plant seeds powder of Nigella sativa L., cucurbita pepo, Sesamum radiatum, Trigonella foenum-graecum, Linum usitatissimum with variable efficiency contra tested microbial strains with concentration of 100 mg/ml, except Sesamum radiatum scored no effect. The T. foenum and N. sativa seed powder showed the largest inhibition zone (24-20 mm) contra K. pneumonia, followed by S. aureus (20-18 mm) and C. albicans (15mm) respectively. The five plant seeds powder exhibited bacteriostatic and bactericidal effects with MIC's 20 and MBC 40 mg/ml against K. pneumonia, and MIC's 40 and MBC 60 mg/ml against S. aureus. The results of this study indicated that plants seeds powder have promising antimicrobial activities and their potential applications in food process. It could be utilized as a natural medicinal alternative instead of chemical substance.
Nesta pesquisa, o pó de sementes de plantas foi avaliado para encontrar seu efeito potencial no controle de doenças de intoxicação alimentar. O efeito antimicrobiano de cinco sementes de plantas foi examinado contra Bacillus cereus, Staphylococcus aureus, Escherichia coli, Klebsiella pneumonia e Candida albicans usando o método de difusão bem. Estudos de atividade antimicrobiana revelaram alto potencial de atividade de sementes de plantas em pó de Nigella sativa L., Cucurbita pepo, Sesamum radiatum, Trigonella foenum-graecum, Linum usitatissimum com eficiência variável contra cepas microbianas testadas com concentração de 100 mg / ml, exceto Sesamum radiatum com pontuação não efeito. O pó de sementes de T. foenum e N. sativa apresentou a maior zona de inibição (24-20 mm) contra K. pneumonia, seguido por S. aureus (20-18 mm) e C. albicans (15 mm), respectivamente. O pó de cinco sementes de plantas exibiu efeitos bacteriostáticos e bactericidas com MIC's 20 e MBC 40 mg / ml contra K. pneumonia, enquanto MIC's 40 e MBC 60 mg / ml contra S. aureus. Os resultados deste estudo indicaram que os pós de sementes de plantas apresentam promissoras atividades antimicrobianas e suas potenciais aplicações em processos alimentícios. Ele poderia ser utilizado como alternativa medicinal natural em vez de substância química.

Medical trainees (i.e., students and residents) provide relevantly insightful perspectives pertaining to their 'medical education' at both undergraduate (i.e., medical school) and graduate (i.e., residency training) levels. Therefore, promoting related trainee-authored publications about such matters is critically important. However, unfortunately, not many medical trainees are able to voice their important education-related research findings in peer-reviewed journals. 'Journal-level' proposals to increase trainees' scientific scholarship are always warranted. Herein, medical journals are called to play an innovative pivotal role in further promoting the desired trend of trainee-authored publications. To that end, periodically throughout the year, mainstream (general or education-focused) medical journals are encouraged to facilitate supplements entirely dedicated to trainee-authored research contributions in the field of 'medical education'. The grounds, dynamics, challenges and benefits of this supplement-based approach are discussed.

Medical student journals (MSJs) refer to a cluster of entirely student-led periodicals that publish student-authored articles. A recent review showed that MSJs characteristically employ a student-friendly and feeble peer review process, which is largely associated with poor quality of published articles. Herein, as a graduate medical student, I call on peer medical students to make an informed decision in refraining from submitting their research work to MSJs for four primary reasons. These reasons, generally, include: 1) opaque peer-review process, 2) lack of MEDLINE® indexing, 3) absence of official journal impact factor scores, and 4) poor article visibility and exposure to scientific community. Furthermore, I encourage students to take advantage of the existing opportunities provided by the professional MEDLINE®-indexed journals in disseminating their research work. These opportunities include: 1) the absolute welcoming calls for student-authored contributions, and 2) the designated 'student contribution corners'. Lastly, I succinctly highlight the joint duties of medical schools, undergraduate research committees, institutional review boards and mentors in publishing the student-authored research work in the professional journals, rather than the MSJs.

BACKGROUND: Iatrogenic ureteric injury is a rare, yet serious operative complication in gynecologic procedures and associated with substantial morbidities such as prolonged hospitalization, additional financial-based ureter-related repairing procedures, impaired renal function, and compromised quality of life. Direct visual identification of ureters can be very challenging in managing patients with primary advanced or recurrent disseminated intraperitoneal gynecologic malignancies, who are referred to complex procedures such as cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). AIMS: To report our single-center experience (feasibility and morbidity) with prophylactic ureteric stents as a routine practice before CRS+HIPEC procedure in managing peritoneal carcinomatosis (PC) from gynecologic malignancies. METHODS: From June-2010 to March-2014, all patients with gynecologic-related PC, managed with CRS+HIPEC, and underwent prophylactic ureteric stents. The data were retrospectively abstracted and analyzed. RESULTS: Fifty-three patients were identified. Almost all PC cases were secondary/recurrence presentations (90.6 %) and originated from ovarian cancer (84.9 %). Optimal cytoreduction microscopic residual disease) was achieved in 35 patients (60 %). Average insertion time of ureteric stents was 8.9 ± 3.3 min. Fifty-two patients (98.1 %) received bilateral ureteric stents. Forty-nine patients (92.5 %) had their ureteric stents removed by the end of procedure. No patient experienced major peri-operative urinary tract-related complications. CONCLUSIONS: Prophylactic ureteric stents appeared to be feasible, potentially safe, and could reduce the risk of iatrogenic ureteric injuries without incurring an increase in urinary tract-related complications. Prophylactic ureteric stenting does not eliminate the necessity for competent anatomical knowledge, meticulous retroperitoneal dissection and direct intra-operative visualization of ureters.

The present study was undertaken to evaluate the effects of feeding the male mice with miso that was prepared with a mixture of microbial starters on the level of lipid peroxidation as a marker of oxidative stress, antioxidant power of hepatocytes, the enzymatic and non-enzymatic antioxidant. The starters that were used in the preparation of miso were Aspergillus oryzae and Pleurotus ostreaus or A. oryzae and Bacillus subtilis. The miso that was prepared with A. oryzae and Bacillus subtilis has more effect on suppressing the oxidative stress and enhancement of endogenous antioxidant of hepatocytes and renal tissue of mice.
