We study the buckling of elastic spherical shells under osmotic pressure with the osmolyte concentration of the exterior solution as a control parameter. We compare our results for the bifurcation behavior with results for buckling under mechanical pressure control, that is, with an empty capsule interior. We find striking differences for the buckling states between osmotic and mechanical buckl...

Proline accumulation is involved in plant osmotic stress tolerance. Given that DNA methylation is related to almost all metabolic processes through regulation of gene expression, we suspected that this epigenetic modification and proline biosynthesis are probably related. To test this, we investigated whether osmotic stress-induced proline accumulation is associated with DNA methylation modific...

Environmental salinity presents a key barrier to dispersal for most aquatic organisms, and adaptation to alternate osmotic environments likely enables species diversification. Little is known of the functional basis for derived tolerance to environmental salinity. We integrate comparative physiology and functional genomics to explore the mechanistic underpinnings of evolved variation in osmotic...

Osmotic stress severely limits plant growth and agricultural productivity. We have used mutagenesis to identify plant genes that are required for osmotic stress tolerance in tomato. As a result, we have isolated a novel mutant in tomato (tos1) caused by a single recessive nuclear mutation that is hypersensitive to general osmotic stress. Growth measurements demonstrated that the tos1 mutant is ...

Ropinirole hydrochloride is indicated in Parkinson’s disease and Restless leg syndrome. In advanced Parkinson’s disease the usual dose of Ropinirole hydrochloride is 0.25 to 5 mg three to four times a day. Hence, an attempt was made to develop a once-a-day controlled release Osmotic drug delivery system. This may offer significant patient benefits by providing enhanced efficacy and reduced side...

BACKGROUND Yeast cells live in a highly fluctuating environment with respect to temperature, nutrients, and especially osmolarity. The Hog1 mitogen-activated protein kinase (MAPK) pathway is crucial for the adaption of yeast cells to external osmotic changes. METHODOLOGY/PRINCIPAL FINDINGS To better understand the osmo-adaption mechanism in the budding yeast Saccharomyces cerevisiae, we have ...

Oral immunization using whole inactivated influenza virus vaccine promises an efficient vaccination strategy. While oral vaccination was hampered by harsh gastric environment, a systematic understanding about vaccine destabilization mechanisms was not performed. Here, we investigated the separate and combined effects of temperature, retention time, pH, and osmotic stress on the stability of inf...

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...
