table grapes (vitis vinifera l. cv. shahroodi) were stored for 45 days under modified atmospher packaging (map) with four gas combination treatments including gc1 (control or air), gc2 (10%co2+5%o2), gc3 (10%co2+15%o2) and gc4 (10%co2 + 60%o2) using two types of polymeric films pp (polypropylene) and pe (polyethylene) at 1oc and 80-90% rh. measurements were carried out after each 15 days at 1oc...

introduction: the purpose of this study was to determine na-ca exchanger 2, 3 (ncx2, 3) protein level changes during 2, 5, 10, 15 days after induction of normobaric hyperoxia (ho) preconditioning. materials and methods: rats were divided in two experimental groups. the first group was exposed to 95% inspired ho for 4 h/day for 6 consecutive days (ho). the second group acted as control, and was ...

To increase understanding of persistent pulmonary hypertension, we examined chronic pulmonary effects of hypoxia at birth and their relationships with immunoreactive levels of the potent vasodilator, calcitonin gene-related peptide (CGRP). Rats were born in 10% hypobaric hypoxia, where they remained for 1-2 days, or in 15% hypoxia, where they remained for 21 days. All were then reared in normox...
