    No full text
    A high resolution continuous wave (CW) spectrometer based on difference frequency generation (DFG) in a 2 cm long AgGaS2 crystal pumped by two stabilized single frequency CW dye / Ti:Sapphire lasers is reported. Infrared generation is achieved from 3 to 9 µm making use of 90° Type I phase matching. The performance of the DFG laser spectrometer has been evaluated using a portion of the V2 band of NH3 near 1177 cm-1

    International audienceIntroduction. Practical training of the surgery resident is based on the companionship currently hampered in particular by the increase of the number of residents in training. We created a teaching tool to promote learning and validation of a technique of classic urologic surgery, inguinal orchidopexy. The objective is to evaluate the applicability and the relevance of this tool. Material and methods. The tool is a technical evaluation sheet made from reference documentation. The trainers evaluated the residents at 3 times of the semester (hetero-evaluation at 0, 3 and 6 months). Residents evaluated themselves monthly on the same items. Results. Three trainers and 6 residents in surgery participated in the study between May and November 2013. The initial evaluation confirmed that the theoretical knowledge was acquired prior to the practical learning. The level of residents was very uneven at the beginning of the study but not at the end of the semester. The monthly evaluations gave a progressive and significant increase of notes. The notes of the intermediate and final hetero-evaluations rose gradually and they were always superior to those previous self-assessments (P< 0.05). The tool was considered simple and useful for the participants. Conclusion. This tool is applicable and relevant to the technical teaching of inguinal orchidopexy in this population. A larger study would be helpful to confirm it. This type of tool could be applied to the simple and common surgery techniques to enrich the educational tools used in the training.

    ABSTRACT Objective: The prevalence of antimicrobial resistance among clinical pathogens is reviewed and its clinical impact on management is increased. Continued surveillance of resistance rates among clinical pathogens is needed to ensure that appropriate recommendations can be made for treatment of infected patients. Since, vancomycin-resistant enterococci (VRE) and methicillin-resistant Staphylococcus aureus (MRSA) are the most important bacteria isolated in this case. Further studies addressing the clinical and bacteriological outcomes of patients infected with a resistant pathogen are needed. The leaves of Globularia eriocephala Pomel (family Globulariaceae) named &quot;Tasselgha&quot; are widely used in North region of Algeria as a folk medicine. Chloroform, ethyl acetate and hydromethanol extracts of Globularia alypum and essential oil were tested against some clinical pathogens bacteria. Methods used: Antibacterial activities were tested against bacteria isolated from surgery in perioperative period using disc-diffusion method and MIC was determined. The compound of essential oils was confirmed using chromatography techniques. Results: The hydromethanolic extract of Globularia eriocephala leaves demonstrated antimicrobial activity against Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae and inactivity against Proteus vulgaris and Escherichia coli. Antibacterial activities were observed in ethyl acetate and hydromethanolic extracts of Globularia eriocephala leaves. The MIC values of the compound against Staphylococcus aureus (75.0mg/ml), Pseudomonas aeruginosa (63.5mg/ml) and Klebsiella pneumonia (62.0 mg/ml). The combination of Chloroform extract and essential oils exerted wielded a synergistic effect for the inhibition against the growth of the Gram-negative and Grampositive bacteria when the MICs were applied. Conclusion: Ethyl acetate extract showed promising antibacterial activity against bacterial responsible of nosocomial infection, and the essential oil compounds showed at all a moderate activity against these bacteria. These results suggested Globularia eriocephala could be a potential source of antibacterial agents. Further investigations are in progress to determine the active constituent(s) for their application in medical research
