BACKGROUND Washing of platelets is an important procedure commonly used for experimental studies, e.g. in cardiovascular research. As a known phenomenon, responsiveness to adenosine diphosphate (ADP) is reduced in washed platelets, although underlying molecular mechanisms-potentially interfering with experimental results-have not been thoroughly studied. OBJECTIVES Since ADP mediates its effe...

Background: Raw or minimally processed vegetables can be important vehicles of food-borne parasites. The main purpose of the present study was to investigate the parasitic infections in raw vegetables from Kermanshah, Western Iran and their relation with season and washing procedures. Methods: From January to December 2013, raw vegetable samples were collected from Kermanshah, Western Iran. Th...

conclusions: vegetables are a new source of h. pylori and accurate washing of vegetables improves such contaminations. results: the results showed that 44 of 460 samples (9.56%) were positive for h. pylori using the culture method. the polymerase chain reaction technique showed that 50 of 460 samples (10.86%) were positive for h. pylori. un-washed leek, traditional salad, un-washed basil and un...

Yamashita and Butler [I] have shown that extraction of chloroplasts with a high concentration of Tris (0.8 M, pH 8.0) eliminates flow of electrons from water to nicotinamide adenine dinucleotide phosphate (NADP+)* or other Hill oxidants. They suggest that washing with Tris causes a block on the water side of the electron transport chain. Addition of electron donors such as reduced phenylene dia...

Irradiation of tris-washed chloroplasts with moderate intensities of red light caused a partial bleaching of chloroplast pigments and an inhibition of the hydroquinonesupported photoreduction of NADP. The presence of an electron donor for photosystem 2 (PS2) during the irradiation prevented the bleaching and inhibition. It is concluded that the strong oxidant produced by PS2 accumulates in tris...

The goal of medical device reprocessing is to ensure that a given device is ready for safe use on the next patient. Effective cleaning of devices is critical to achieving this goal. Device cleaning also has had an ancillary goal: rendering the device safe for handling with ungloved hands by sterile processing personnel. Such personnel are tasked with preparing the device for further reprocessin...
