abstract: in this study the reliability of using response surface-neural network method to predict the osmotic dehydration properties of crookneck squash has been investigated. in order to carry out this project, the osmotic solution concentration, the osmotic solution temperature and immersion time were chosen as inputs and solid gain and water loss were selected as outputs of the designed net...

in this research, the effect of ultrasound-osmotic dehydration process in different conditions on the drying kinetics parameters of rhubarb was investigated. before dying process, rhubarb samples were placed in contact of ultrasound-osmotic pretreatment and then dried by convection hot air dryer equipped with circulated fan. the results showed that using osmotic pretreatment at 40% sucrose solu...

BACKGROUND The intervertebral disc (IVD) is a special tissue localized in the middle of vertebrae and it often experiences osmotic environment to accommodate applied mechanical forces. AIM Here we aim to confirm significant pathways associated with IVD osmotic regulation. MATERIALS AND METHODS Two different pathway analyses which are named component-based approach and protein-protein intera...

Environmental stresses specially drought, play an important role in decreasing plant growth, particularly during germination in dry and semi dry area. To considering the effect of drought stress caused by polyethylene glycol on germination and characteristics of 2 spices of Sesamum indicum, we had done factorial and complete accidental plot with 4 treatments and 3 times repetition. Experimental...

Assessing the tolerance of medicinal plants is important for planting them in drought areas. Arginine is a growth regulator and its role in plants’ tolerance to environmental stresses such as drought has been investigated. To evaluate the protective effects of arginine against osmotic stress induced by polyethylene glycol in ajwain (Trachyspermum ammi) seedlings, an experiment was conducted as ...

When third-stage larvae of Pseudoterranova decipiens maintained at 5 degrees C are placed in either 40% artificial sea water (ASW, iso-osmotic) or 15% ASW (hypo-osmotic) and weighed once at 0 h and again at 24 h, they neither lose nor gain weight, and the osmotic pressure (OP) of their pseudocoelomic fluid (PCF) remains unchanged. In contrast, when worms are weighed six additional times during ...

Osmotic stress associated with drought or salinity is a major factor that limits plant productivity. Protein kinases in the SNF1-related protein kinase 2 (SnRK2) family are activated by osmotic stress, suggesting that the kinases are involved in osmotic stress signaling. However, due to functional redundancy, their contribution to osmotic stress responses remained unclear. In this report, we co...

Cells of tomato (Lycopersicon esculentum) growing in suspension gradually depleted their culture medium and caused a steady decrease in its osmolality. When confronted with a sudden change in medium osmolality (a hypo-osmotic or hyperosmotic shock), respectively, these cells responded with volume changes and stress symptoms such as rapid extracellular alkalinization, efflux of K(+)-ions, and in...

Preparation and in vitro and in vivo evaluation of vinpocetine (VIN) elementary osmotic pump (EOP) formulations were investigated. A method for the preparation of VIN elementary osmotic pump tablet was obtained by adding organic acid additives to increase VIN solubility. VIN was used as the active pharmaceutical ingredient, lactose and mannitol as osmotic agent. Citric acid was used as increasi...
