objective: hydrostatic pressure is crucial component of cell environment and fundamental physical quantity, also it is the main factor of both cell integrity and function. pressure variation disorder, beyond physiological limits, may lead to pathological states. in this study, we examined the effect of hydrostatic pressure on apoptosis induction, viability, morphology, adhesion potency to subst...

In this study, iron reduction and concomitant biomineralization of a deep-sea iron reducing bacterium (IRB), Shewanella piezotolerans WP3, were systematically examined at different hydrostatic pressures (0.1, 5, 20, and 50 MPa). Our results indicate that bacterial iron reduction and induced biomineralization are influenced by hydrostatic pressure. Specifically, the iron reduction rate and exten...

Background. Intussusception is the most common cause of bowel obstruction in children under two years of age. The proximal part of the bowel and its mesentery (the intussusceptum) enter within that part immediately beneath it (the intussuscipiens). Being pulled by peristalsis the mesenterial vessels get compressed which result in ishaemia of the bowel wall. Most intussusceptions are ileocolic. ...

Barium enema hydrostatic reduction was carried out for eight patients with Intussusception over a six-month period There were five successes (62%) and three failures. There were no mortality or complications arising out of this procedure. The technique is discussed This procedure offers many advantagesover surgicalreduction. However, it is not a substitute for surgery which is still indicated i...

To provide guidelines for the choice of treatment of intussusception, 10 factors that are known to be related to the outcome of treatment were studied in a series of 146 children with intussusception. The length of history, vomiting, rectal bleeding, small bowel obstruction, ileoileocolic intussusception, and the presence of a leading point were all significantly related to failure of hydrostat...

BACKGROUND Reduction of intussusception under ultrasound guidance by saline has become popular in recent years. However, methods, duration of the procedure and causes of failure are not defined. In this study, we reviewed the patients who underwent ultrasound (US) guided saline reduction and compared them with those who were previously managed by operative intervention. METHODS Patients with ...

DESCRIPTION A 2-year-old previously well girl presented at the hospital with intermittent acute painful crying (colicky pain) that recurred at frequent intervals for some hours. Between these episodes, she was painless but refused to eat or drink. During palpation, a mass was suspected in the right hemiabdomen. The rectal examination was unremarkable, and no bloody diarrhoea was present. Abdomi...

The objective of this study was to identify ERK 1/2 involvement in the changes in compressive and tensile mechanical properties associated with hydrostatic pressure treatment of self-assembled cartilage constructs. In study 1, ERK 1/2 phosphorylation was detected by immunoblot, following application of hydrostatic pressure (1 h of static 10 MPa) applied at days 10-14 of self-assembly culture. I...
