Appropriate management of raised intracranial pressure begins with stabilization of the patient and simultaneous assessment of the level of sensorium and the cause of raised intracranial pressure. Stabilization is initiated with securing the airway, ventilation and circulatory function. The identification of surgically remediable conditions is a priority. Emergent use of external ventricular dr...

This article describes the fabrication and use of microfluidic devices for investigating spatial orientation behaviors in nematode worms (Caenorhabditis elegans). Until now, spatial orientation has been studied in freely moving nematodes in which the frequency and nature of encounters with the gradient are uncontrolled experimental variables. In the new devices, the nematode is held in place by...

BACKGROUND Water transport in peritoneal dialysis (PD) patients occurs through the small pores and water channels, the latter allowing free water transport (FWT). The osmotic gradient is known to be one of the major determinants of water transport. The objective of the study was to analyse the relation between each transport route and the osmotic gradient. METHODS The 4-h standard peritoneal ...

Growth-chamber studies were conducted to examine the ability of seven vegetable crops-‘Blue Lake’ bean (Phaseolus vulgaris L.), ‘Detroit Dark Red’ beet (Beta vulgaris L.), ‘Burgundy’ okra (Abelmoschus esculentus (Moench), ‘Little Marvel’ pea (Pisum sativum L.), ‘California Wonder’ bell pepper (Capsicum annuum L.), ‘New Zealand’ spinach (Spinacia oleracea L.), and ‘Beefsteak’ tomato (Lycopersico...

The different leaf water parameters, Le., totalleaf water potential (\}Jt), leaf osmotic potential at full turgor ('P S100) leaf osmotic potential at zero turgor (\PSO), relative water content at zero turgor (RWCO) and relative dry weight of the leaf (RDW) were studied during four growth stages in five varieties of sweet sorghum under various soil moisture regimes. In all the varieties, severel...

Water defi cit in the soil leads to osmotic stress in plants. The type of stress affects plant water relations, osmolyte accumulation and oxidative stress balance. The present study aimed to investigate the effects of osmotic stress on the Croatian perennial species Fibigia triquetra (DC.) Boiss, adapted to a hot and dry habitat. Plants grown in culture conditions were subjected to isoosmotic c...

Osmotic drug delivery mechanism is well known in the field of oral controlled release systems. The release of drug from the osmotic drug delivery devices is based on the phenomenon of osmosis. An useful technology developed for osmotic delivery of drug is asymmetric membrane capsule (AMC), which is an economic and effective drug delivery device as compared to other existing technique of osmotic...

The changes in the osmotic resistance of red blood cells (RBC), due to various pathological conditions like exposure to heat, anemia as well as the effect of storage and anticoagulants have been investigated. The results have shown that exposure to a temperature of 50 degrees C makes the red blood cells fragile to osmotic pressures. Also, red blood cells from the patients suffering from anemia ...
