Background: In many clinical situations, knowledge of central venous pressure (CVP) is important.  Measurement of CVP is not always possible. Objective: To determine if intraocular pressure (IOP) can be used as an estimate for CVP. Methods: IOP and CVP were measured concurrently in 30 candidates of coronary artery bypass graft surgery.  Those with carotid artery or jugular venous diseases as we...

osmotic dehydration under discontinuous reduced pressure is one of the new methods of preparation fruits and vegetable processing with in view of good health. processing of foods at high temperatures used to cook them can cause the formation of carcinogenic substances like acrylamide, and this risk remains even if the trans-fat is removed. the low temperatures employed in this method resulted i...

introduction: finding the probable governing pattern of peep and cvp changes is an area of interest for in-charge physicians and researchers. therefore, the present study was designed with the aim of evaluating the relationship between the mentioned pressures. methods: in this quasi-experimental study, patients under mechanical ventilation were evaluated with the aim of assessing the effect of ...

introduction: to study the effects of exercise, how important it is to choose a posture? we aimed to characterize the possible impact of different body positions on cardiovascular parameters during and after sustained isometric handgrip (ihg) exercise. materials and methods: cross sectional study was carried out in 33 young adult males (mean age: 19.21±1.083 years). we recorded blood pressure (...

conclusions it seems that severe pah aggravates the rv function more severely. results significant tricuspid regurgitation was more prevalent in the pah group than in the ps group (61% vs. 18.5%; p < 0.001). the abnormalities in the rv myocardial performance index, rv areas, and rv fractional area change were significantly more robust in the pah group (all ps < 0.05) despite the higher net rv s...

purpose: to evaluate the effect of trans-scleral cyclophotocoagulation (tscpc) in reducing intraocular pressure in eyes with history of pars plana vitrectomy with or without intraocular silicone oil and refractory to medical treatment. methods: medical records of 35 eyes of 35 patients who underwent tscpc for medically uncontrolled glaucoma after pars plana vitrectomy for retinal pathology were...

background: irradiation of water by uv has been considered as an attractive alternative for disinfection because its low- im pact, pathogen killing capacity shows tremendous promise for meeting today’s drinking water regulatory requirements. this study has been performed with the objective of utilizing medium pressure lamp in the preliminary stage of municipal wa ter treatment, namely prior to ...

background crocus sativus l. (saffron), which belongs to the iridaceae family, is widely cultivated in iran. cardiovascular effects of saffron has been established in some studies but the effects of chronic administration of saffron (c. sativus) stigma aqueous extract on blood pressure has not been investigated. objectives in this study the effects of saffron (c. sativus) stigma aqueous extract...
