This paper describes total determination of aflatoxins B1 and B2 in pistachio samples using corona discharge ion mobility spectrometry (IMS). A new injection port was designed to introduce liquid samples into the IMS. Using this port, the liquid solvent (methanol) containing standard aflatoxins or an extracted sample was directly introduced into the injection port. Calibration curves resulting ...

This work investigates arsenic mobility, bioavailability and toxicity in marine port sediments using chemical sequential extraction and laboratory toxicity tests. Sediment samples were collected from two different Mediterranean ports, one highly polluted with arsenic and other inorganic and organic pollutants (Estaque port (EST)), and the other one, less polluted, with a low arsenic content (Sa...

BACKGROUND Port systems are easy to implant on an in- or outpatient basis and provide reliable, long-lasting central venous access. They are used mainly for cancer patients. METHODS This article is based on a selective literature review, the guidelines of the German Society for Nutrition Medicine and of the European Society for Clinical Nutrition and Metabolism, and the recommendations of the...

background port site complications following elective surgery are rare and port site infections remain the most common short long term complications. objectives the study was conducted to analyze port site complications occurring in patients undergoing laparoscopic cholecystectomy for symptomatic cholelithiasis. patients and methods ninety patients undergoing laparoscopic cholecystectomy were r...

A twin six-port valve with two sample loops was installed between the autosampler and the nebuliser of a simultaneous inductively coupled plasma-atomic emission spectrometer. The valve was mounted close to the nebuliser inlet so that the time required for the sample to enter from the loop to the nebulizer was less than 0.5 s. The content of one loop was introduced to the nebulizer using a peris...

peripherally inserted venous ports fracture with embolization in patients who received chemotherapy is a serious and rare complication,and few cases have been reported in children. we report a successful endovascular technique using a snare for retrieving broken peripherally inserted venous ports in a child for chemotherapy. catheter fragments may cause complications such as cardiac perforation...

evidence acquisition a systematic literature searching of databases medline, embase, and google scholar was done from 1982 and updated in december 2015. search terms were “cholecystectomy”, “laparoscopic cholecystectomy”, “four port laparoscopic cholecystectomy”, “single-incision laparoscopic surgery”. context laparoscopic approach with its several techniques has become the standard method for ...

This paper examines the empirical relationship between maritime connectivity and port efficiency. To do so, a stochastic output distance function is employed which permits effect of on technical efficiency to be estimated for sample Spanish ports. Previous studies analysing have used country-level indices. In present study, port-level indices are first time this type analysis. A novel panel dat...
