abdominal wall hernias are common problems found in patients with cirrhosis because of persistently high intra-abdominal pressure. when abdominal hernias are neglected in such patients, they may become larger and could result in cosmetic problems and pressure effects that are also difficult to treat. we found a voluminous mass in the anterior abdominal wall of a 40-year-old patient with cirrhos...

background ziziphora tenuior l. known as kakuti in persian, is used in traditional medicine for fever, dysentery, uterus infection and as an analgesic. it is used also in the treatment of gastrointestinal disorders as carminative, or remedy of diarrhea or nausea. major components of plant essential oil including pulegone, isomenthone, thymol, menthone, and piperitone are suggested to be respons...

background valproic acid is widely used as an anticonvulsant and mood-stabilizing drug in the treatment of epilepsy. determination of serum valproic acid is required in epilepsy therapy for efficient control of seizures. objectives in the present study, the gas chromatography method was applied to determine serum valproic acid and resulting data were compared with those obtained by high perform...

this paper reviews the possible effects determined on polymeric food packaging films by the simultaneous application of pressure (p) and temperature (t) in high pressure pasteurization and sterilization treatments of packaged foodstuffs. both theoretical modeling and experimental issues are discussed. in fact reversible and irreversible effects that could occur in single film as well as in mult...

pressure refers to the feelings an athlete has about performing in a competitive situation. the primary aim of this study was to examine kinematic changes of tennis serves in increasing competitive pressure. 20 semi-professional right-handed male tennis players completed 120 serves under low (normal) and high competitive pressure phases. pressure checks (heart rate and perceived competitive sta...

Received: February 10, 2017 Revised: May 24, 2017 Accepted: June 02, 2017 Abstract: Background: The use of backpressure regulator valves is widespread in high-pressure processes both at laboratory and pilot plant scales, but being a single step for effluent depressurization, such valves may have some limitations at industrial scale. In an effort to improve the depressurization step, this work s...

Existing pneumatic artificial muscles generally rely on the use of either positive or negative pressure for actuation with each having their own advantages and disadvantages. Herein, a hyperbaric vacuum-based muscle (Hyper-VAM) making both pressures almost interchangeably is described. This done by placing actuator inside chamber which enables large deformations possible using pressure, forces ...
