We have reported that high-hydrostatic-pressure (HHP) technology is safe and useful for producing various kinds of decellularized tissue. However, the preparation of decellularized or inactivated skin using HHP has not been reported. The objective of this study was thus to prepare inactivated skin from human skin using HHP, and to explore the appropriate conditions of pressurization to inactiva...
pressurized injection operation means the pressurized injection of a liquid or solution into pore of a mass of soil or stone and/ or cavity between them and built structures. the injected mortar mustconstitute a soil and/ or jel- like matter inside the cavites, and/ or the operations of the injection must cause sedimentation of the solid matter suspending in these cavites. the primary purpose o...
introduction: nowadays, efficient use of scarce water resources is one of the government’s importantgoals for dealing sustainable development in the agricultural sector. in addition to optimal exploitation and using of surface and groundwater resources, choosing of efficient types of irrigation technologies is a very important factor in sustainable water resource management. this study tries to...
The hydrothermal synthesis of zeolites carried out in batch reactors takes a time so long (typically, on the order of days) that the crystallization of zeolites has long been believed to be very slow in nature. We herein present a synthetic process for ZSM-5, an industrially important zeolite, on the order of seconds in a continuous flow reactor using pressurized hot water as a heating medium. ...

Gokina, Natalia I., and George Osol. Temperature and protein kinase C modulate myofilament Ca21 sensitivity in pressurized rat cerebral arteries. Am. J. Physiol. 274 (Heart Circ. Physiol. 43): H1920–H1927, 1998.—The effects of pharmacological activation and inhibition of protein kinase C (PKC) and temperature on the relationship between cytoplasmic Ca21 and lumen diameter were studied in pressu...
زخم های فشاری، یکی از عوارض ناخواسته درمانی بوده و اکثراً با درک هوشیاری و مراقبت بموقع قابل پیشگیری است. امروزه زخم های فشاری یا زخم بستر یکی از مسائل بغرنج درمانی محسوب می شود و این مسئله تا حد زیادی مربوط به این واقعیت است که، تعداد بسیاری از بیماران سالخورده از بیماری های جدی و حاد جان سالم بدر برده ولی به علت سالخوردگی و پاتولوژی عوامل چندگانه بیشتر در معرض ابتلاء به زخم های بستر می باشند.
