چکیده
Accepted for publication 26 March 1991 Abstract The oesophageal acid clearance time was evaluated in 10 healthy volunteers of 'small' boluses of 0 5 and 1 ml and 'minute' boluses of 0-05 and 0*1 ml 0.1 N HCI, as well as 0-1 and 1 ml 0*01 and 0.001 N HCI. Swallow rate was normalised at q 60 seconds. For 0.1 ml 0.1 N HCI, acid clearance time was also measured for swallow intervals of q 30 and 120 seconds. Acid clearance time to restore pH to 4 0 was significantly longer (p<001) for the 05 and

,Different variations of Aplysia have been appealing options in medical and pharmaceutical researches for years. Persian Gulf’s sea hare—Aplysia dactylomela—is a species native to Persian Gulf and can be evaluated in various areas. In this research, carried out in 2019 in Persian Gulf University’s Research Centre, the antibacterial potential of the ink of this species has been measured against ...
متن کاملMesoscale blood cell sedimentation for processing millilitre sample volumes.
We demonstrate the efficient separation of blood cells from millilitre volumes of whole blood in minutes using a simple gravity sedimentation device. Blood cell and plasma separation is often the initial step in clinical diagnostics, and reliable separation techniques have remained a major obstacle for the success of point-of-care or remote diagnostics. Unlike plasma collection devices that rel...
متن کاملThe toxicity of metals used in orthopaedic prostheses. An experimental study using cultured human synovial fibroblasts.
Some of the component metals of the alloys used for total joint prostheses are toxic and dissolve in the body fluids. It is important to establish how toxic these metals are and to assess the risk of localised tissue necrosis around the prostheses. This has been investigated by incubating primary monolayer cultures of human synovial fibroblasts with various preparations of metals for periods up...
متن کاملThe use of sensitivity discs in the identification of Campylobacter species.
Filter paper discs were impregnated with a solution containing 20 mg of triphenyltetrazolium chloride per millilitre, and used in the typing of catalase-positive Campylobacter species. Also used were filter paper discs impregnated with cephalothin at 30 micrograms/ml, 60 micrograms/ml and 3 mg/ml and nalidixic acid at the same concentrations, as well as commercially available discs containing 3...
متن کاملAutomatic determination of cobalt at the submicrogram per millilitre level using a flowthrough spectrophotometric sensor.
A flowthrough spectrophotometric sensor for the determination of cobalt at the nanogram per millilitre level using pyridoxal 4-phenylthiosemicarbazone as reagent and integrated preconcentration and detection in the flow cell is proposed. The method is highly selective for cobalt(II); it features detection and determination limits of 0.02 and 0.06 mug ml(-1) respectively, and a linear range of a...
