PURPOSE To investigate the effect of various riboflavin/ultraviolet light (UVA) crosslinking (CXL) protocols on corneal enzymatic resistance. METHODS A total of 66 enucleated porcine eyes, with the corneal epithelium removed, were divided into 6 groups. Group 1 remained untreated. Groups 2 to 6 received riboflavin/dextran for 30 minutes. Group 3 underwent standard CXL (SCXL) with 3 mW/cm(2) U...

BACKGROUND In order to avoid microaspiration and tracheal injury, the target for endotracheal tube cuff pressure is 20 to 30 cm H2O. OBJECTIVE To assess the effect of changes in body position on cuff pressure in adult patients. METHODS Twelve orally intubated and sedated patients received neuromuscular blockers and were positioned in a neutral starting position (backrest, head-of-bed elevat...

Background:  Wi-Fi allows electronic devices such as laptops to exchange data or connect to a network resource. The main goal of this study was to assess the bioeffects of short term exposure to 2.4 GHz microwave radiation emitted from a common Wi-Fi router on sperm quality. Materials and Methods: Male Wistar rats were divided into 7 groups; I, sham exposed 4 h/day for 7days at 30 cm from ...

plant litter is an important factor for soil conservation and sustainability that could modify soil chemical properties and increase the plant biomass production. the aim of this research was to compare plant litter chemical composition and its effects on soil properties in three species including hordeum bulbosum, poa bulbosa, bromus tectorum. first, soil samples were taken in the depth of 0-3...

Formation of atelectasis is one mechanism of impaired gas exchange during general anaesthesia. We have studied manoeuvres to re-expand such atelectasis in 16 consecutive, anaesthetized adults with healthy lungs. In group 1 (10 patients), the lungs were inflated stepwise to an airway pressure (Paw) of 10, 20, 30 and 40 cm H2O. In group 2 (six patients), three repeated inflations up to Paw = 30 c...

Introduction It is well-known that exposure to an enriched environment (EE) can induce plastic changes in the hippocampus and improves learning and memory in hippocampus-dependent tasks. The commonly used techniques in the previous studies on the effects of EE on brain include behavioral tests, electrophysiological recording, microdialysis and morphological evaluations of neurons and synapses. ...

An antimicrobial-surface kinetic test which maximizes probability of cell-to-surface contact has been developed. The measurement of rate of kill by a nonleaching antimicrobial surface is based on the number of surviving bacterial cells at specific times of exposure to various amounts of total treated surface area of test substrate. This method gives information for direct comparison of rate of ...
