AIM:To evaluate the feasibility and the outcome of endoscopic mucosal resection(EMR)for large colorectal tumors exceeding 4 cm(LCRT)undergoing piecemeal resection. METHODS:From January 2005 to April 2008,146 digestive tumors larger than 2 cm were removed with the EMR technique in our *** these,34 tumors were larger than 4 cm and piecemeal resection was carried out on 26 colorectal *** mean age of the patients was 71 *** mean follow-up duration was 12 mo. RESULTS:LCRTs were located in the rectum,left colon,transverse colon and right colon in 58%,15%, 4%and 23%of cases,*** were sessile tumors larger than 4 cm with a mean size of 4.9 cm (4-10 cm).According to the Paris classification,34%of the tumors were typeⅠs,58%typeⅡa,4%typeⅡb and 4%typeⅡ*** examination showed tubulous adenoma in 31%,tubulo-villous adenoma in 27%,villous adenoma in 42%,high-grade dysplasia in38%,in situ carcinoma in 19%of the cases and mucosal carcinoma(m2)in 8%of the *** two cases(7.7%)of procedural bleeding that occurred were managed endoscopically and one small perforation was treated with *** follow-up,recurrence of the tumor occurred in three patients(12%),three of whom received endoscopic treatment. CONCLUSION:EMR for tumors larger than 4 cm is a safe and effective procedure that could compete with endoscopic submucosal dissection,despite providing incomplete histological assessment.

The objective of this work research is the use of four-point measurements and so-called Van Der Pauw methods in measuring the resistivity of copper thin films widely used in the manufacture of planar components such as inductor and others. Aligned configuration and square configuration are commonly used to measure thin films resistivity before use. But differences in values between the two configurations according to frequency and thickness were observed according to the authors. Measurements with both configurations on the same thin films must make it possible to know measurements evolution as a function of frequency and thickness. The observation of measuring frequency ranges of each configuration and the minimum thicknesses to have solid copper resistivity are the main contributions of the paper. This electrical characterization is carried out on copper thin films deposited on alumina substrates (50 mm × 20 mm × 635 μm) using RF sputtering technique. Copper thin films with various thicknesses (3.3 μm, 3.6 μm and 5.2 μm) were characterized. Low-frequency electrical characterization of these thin films was performed by four-point measurement method and using an HP 4284A type LCRmeter over the frequency range of 20 Hz to 1 MHz. Van der Pauw’s method was used to calculate resistivity. These studies allowed us to know influence of measurement configurations and influence of parameters such as frequency and thickness of the copper thin films on resistivity.

The reclamation and disinfection of waters impacted by human activities（e.g., wastewater effluent discharges） are of growing interest for various applications but has been associated with the formation of toxic nitrogenous disinfection byproducts（N-DBPs）. Monochloramine used as an alternative disinfectant to chlorine can be an additional source of nitrogen in the formation of N-DBPs. Individual toxicity assays have been performed on many DBPs, but few studies have been conducted with complex mixtures such as wastewater effluents. In this work, we compared the cytotoxicity and genotoxicity of wastewater effluent organic matter（Ef OM） before and after chloramination. The toxicity of chloraminated Ef OM was significantly higher than the toxicity of raw Ef OM, and the more hydrophobic fraction（HPO）isolated on XAD-8 resin was more toxic than the fraction isolated on XAD-4 *** DBPs were also isolated on the XAD-8 resin. N-DBPs（i.e., haloacetonitriles or haloacetamides） were responsible for the majority of the cytotoxicity estimated from DBP concentrations measured in the XAD-8 and XAD-4 fractions（99.4% and 78.5%, respectively）.Measured DBPs accounted for minor proportions of total brominated and chlorinated products, which means that many unknown halogenated compounds were formed and can be responsible for a significant part of the toxicity. Other non-halogenated byproducts（e.g.,nitrosamines） may contribute to the toxicity of chloraminated effluents as well.

Background and Aim: Ecthyma gangrenosum (EG) is a rare necrotic skin infection caused by Pseudomonas aeruginosa occurring on healthy skin mainly, but not exclusively, in immunocompromised patients. We report the case of EG of unusual presentation in a 12-month-old infant. Case Presentation: This was a 12-month-old male infant who was referred from a peripheral structure for the treatment of facial swelling associated with fever. In his antenatal and intra nasal history, there was a notion of hospitalization for 15 days for early neonatal infection and a delay in psychomotor development. The admission examination showed the fair general condition, hyperthermia at 39°C, tachycardia at 136 beats/minute, and polypnea at 48 cycles/minute. The weight-for-height index with a z-score of 3DS was also found. The dermatological examination at the entrance found an extensive brownish inflammatory tense infiltrated plaque taking the mandibular, submental, retro-auricular occipital regions rapidly evolving towards necrosis, a significant swelling predominant on the upper right eyelid preventing the opening of the associated eyes to mouth ulceration. Biological abnormalities were predominantly neutrophilic leukocytosis, elevated CRP, and elevated muscle enzymes. Microbiological examination of skin samples had isolated Pseudomonas aeruginosa. He had received antibiotic therapy, and a necrosectomy under general anesthesia. The evolution was favorable and he was discharged from the hospital on D26 of hospitalization. Conclusion: This observation is rare due to its location, its early onset, and non-neutropenic background.

The White-breasted Thrasher (Ramphocinclus brachyurus) is the smallest passerine bird in the Mimids family. Ranked as “endangered” in the IUCN list, the demographic distribution of this species is spread unevenly across two islands in the Lesser Antilles. The Saint-Lucian subspecies, Ramphocinclus brachyurus sanctaeluciae, was estimated to number between 1200 and 1700 individuals, whereas the Martinique subspecies, Ramphocinclus brachyurus brachyurus, was estimated at between 200 and 400 individuals. As an endemic rare species with a high risk of extinction, the Martinique subspecies should be regarded as a conservation priority. The small size of the Martinique subspecies population, its restricted geographical range, and its narrow habitat tolerance make it quite difficult to study. The variability of morphological traits in this subspecies has not been biostatistically analyzed recently. In order to update knowledge and fill in any gaps, we have used the morphometric approach to study the morphological variability of the Martinique subspecies. The study site is a small peninsula located in the northeast of the island of Martiniqu
