Perfluoroisobutylene (PFIB) is produced as a main by-product in large quantities by the fluoropolymer industry. As a highly toxic compound, even the case of brief inhalation of PFIB can result in acute lung injury (ALI), pulmonary edema and even death. To test for any preventive or therapeutic effects of pyrrolidine dithiocarbamate (PDTC), a NF-kappaB activation inhibitor, against PFIB inhalati...

Field monitoring of volumetric soil water content (VWC) is critical for a variety of applications. Recently developed electronic soil water sensors provide a relatively inexpensive monitoring option. However, the calibration of these sensors is more sensitive to variations in soil properties than for time domain reflectometry (TDR), which is generally regarded as the best electronic means of VW...

OBJECTIVE Robust markers of subclinical perioperative lung injury are lacking. Extravascular lung water indexed to predicted body weight and pulmonary vascular permeability index are two promising early markers of lung edema. We aimed to evaluate whether extravascular lung water indexed to predicted body weight and pulmonary vascular permeability index would identify patients at risk for clinic...

to study the effect of salinity stress on some physiological attributes of four grape cultivars in vineyards of urmia in iran, an experiment was carried out as factorial arrangement in randomized complete block design with four replications. experimental factors included: grape cultivars qazel ozum, qareh shireh, tabrzeh and dizmari, and salt concentrations 0, 25, 50 and 100 mmol l-1 and locati...

The objective of the present study was to examine the relationship among extravascular pulmonary water, intracranial and cerebral perfusion pressure, hemodynamic parameters (eg, cardiac index, system vascular resistance index), and brain stem function during acute ischemic stroke. The subjects were 17 comatose patients with ischemic stroke who were admitted to an intensive care unit. The result...

throughout the present research, squash (cucurbita pepo) slices (0.4 cm thickness and 4 cm diameter) were blanched in a steam chamber for 4 min. following cooling to room temperature, the squash slices were dehydrated by use of a hotair dryer, under air temperature of 60°c up to moisture content of 0.1065 kg h2o per kg d.m. squash slices of specified weights were rehydrated by immersion in dist...

BACKGROUND Drinking mate has been associated with cancers of the esophagus, oropharynx, larynx, lung, kidney, and bladder. We conducted this study to determine whether drinking mate could lead to substantial exposure to polycyclic aromatic hydrocarbons (PAH), including known carcinogens, such as benzo[a]pyrene. METHODS The concentrations of 21 individual PAHs were measured in dry leaves of ei...

Objective: Physical exercise has different effects on oxidative stress. Oxidative stress influences TLR4 and NFkB gene expression. The purpose of this study was to investigate the effect of aerobic training and vitamin D on gene expression of TLR4 and NFkB in lung tissue of obese rats exposed to oxygenated water. Materials and Methods: In an experimental study, 30 obese male wistar rats were r...

Substantial progress has been made in understanding the role of the distal airway and alveolar epithelial barriers in regulating lung fluid balance. Molecular, cellular, and whole animal studies have demonstrated that reabsorption of fluid from the distal air spaces of the lung is driven by active sodium transport. Several different in vivo, in situ, and isolated lung preparations have been use...
