9% in the baseline phase. However, government and private medical colleges, as well as government and private hospitals across India, were part of recruitment of respiratory patients for this survey. Conclusions It is feasible to conduct a large multisite study to assess respiratory disease burden. Challenges include low response rate and logistic issues.OBJECTIVE Given current clinical interest in vagus nerve stimulation (VNS), there are surprisingly few studies characterizing the anatomy of the vagus nerve in large animal models as it pertains to on-and off-target engagement of local fibers. We sought to address this gap by evaluating vagal anatomy in the pig, whose vagus nerve organization and size approximates the human vagus nerve. APPROACH Here we combined microdissection, histology, and immunohistochemistry to provide data on key features across the cervical vagus nerve in a swine model, and compare our results to other animal models (mouse, rat, dog, non-human primate) and humans. MAIN RESULTS In a swine model we quantified the nerve diameter, number and diameter of fascicles, and distance of fascicles from the epineural surface where stimulating electrodes are placed. We also characterized the relative locations of the superior and recurrent laryngeal branches of the vagus nerve that have been implicated in therapy limiting side effects with common elarities and differences across species.

Results of the previous drug repurposing by virtual screening of DrugBank revealed the anticholinergic drug cycrimine as a possible inhibitor of the influenza virus infection. METHODS In this study we examined the potential antiviral activity of cycrimine in vitro. selleck RESULTS The experimental results showed the anti-influenza activity of cycrimine against two different influenza A subtypes in cell culture. CONCLUSIONS The findings of this study suggest cycrimine as the potential therapeutic agent for influenza.P-glycoprotein (P-gp) and βIII-tubulin overexpression-mediated drug resistance leads to clinical therapy failure for paclitaxel. However, the development of paclitaxel-resistance reversal agents has not had much success. In this study, EM-E-11-4, a lathyrane-type diterpenoid extracted from Euphorbia micractina, demonstrated good anti-MDR (multidrug resistance) activity in paclitaxel-resistant tumor cells overexpressing either P-gp or βIII-tubulin. EM-E-11-4 was able to recover the effects of paclitaxel in inducing arrest at G2/M phase and apoptosis in both A549/Tax (P-gp overexpression) and Hela/βIII (βIII-tubulin overexpression) cells, respectively, at a non-cytotoxic dose. EM-E-11-4 could enable Flutax-1 and Rhodamine 123 be accumulated intracellularly at an accelerating rate in A549/Tax cells by inhibiting the activity of P-gp ATPase, rather than affecting the expression of P-gp. In addition, it also strengthened the effects of paclitaxel in promoting tubulin polymerization and the binding of paclitaxel to microtubules in vitro. It inhibited the expression of βIII-tubulin in Hela/βIII cells in a dose-dependent manner while not exerting influence on the other β-tubulin subtypes. As far as we know, this is the first study to report that a small molecule natural product could specifically inhibit the expression of βIII-tubulin. These results suggest EM-E-11-4 may serve as a promising MDR reversal agent, particularly for patients bearing tumors with high expression of P-gp and βIII-tubulin.The measurement performance of 13 biochemistry parameters (CEA, CA 19-9, amylase, lipase, sodium, potassium, chloride, creatinine, glucose, protein, albumin, LDH, triglycerides) was tested in a panel of biological fluids other than blood and urine (peritoneal, pleural, pancreatic fluids ...). Our protocol, based on a risk analysis, allowed us to justify our choices and compare the performance obtained with those of the serum or plasma matrix already validated. Thus, the coefficients of variation obtained in body fluids are comparable. The assessment of accuracy (spiking and dilution tests) shows the absence of bias, which is consistent with the absence of matrix effect. The linearity studied by dilution tests shows that the upper limits of the measurement interval communicated by the supplier are applicable to body fluids. The absence of contamination and stability have been also confirmed. All analytes are stable for 3 days at room temperature, 7 days between 2 and 8̊C, and 6 months at -20̊C; except LDH and lipase. For most analytes, at least one interference (hemolysis, icterus, lipemia) was found. Finally, a bibliographical study, confronted with the experience of prescribers, led us to define optimal thresholds to help interpret patients' results. In conclusion, this work has allowed us to validate analytical methods for body fluids testing after relying on their comparability to the blood matrix. We have also been able to adapt our practices and finally be accredited according to the standard NF IN ISO 15189.Serum proteins and urinary proteins electrophoresis are useful biological tests. They are often prescribed for the screening of monoclonal gammopathys and also during follow-up for treatment response. This test can be accredited according to standard NF ISO 15189 since laboratories use analysers and adapted reagents, but there are numerous protocols for the method validation. This paper present the results of a survey proposed in 2019 to biologists by CNBH and SFBC. The aim of this survey is to give biologists a choice among several protocols that have been positively evaluated by COFRAC.This is a prospective study realized at the level of the hematology department and blood transfusion center of the University Hospital Center (CHU) of Dr Ben Badis of Constantine and spread out over a period of one year (from January 1st to December 31st). The work focused on the analytical processes mastery of the NFS needs a compulsory step concerning technical and organizational laboratory skills respecting the ISO 15189 laws going through a mastery of support processes (humain resourses, informatics, materials, documents, management) indispensable for the good function of analytic proceedings, a performance evaluation of the hematology analyzer Advia (2120 I and II and 560) and quality control management (intern, extern). The analytic performance evaluation of Advia gives reliable results reproductible and stable for use of the routine automatisation good inter-machine correlation and laboratory performance in terms of the quality extern evaluation with military hospital laboratory.
