Salt accumulations in aquifers significantly affect and transform the conjunctive use of surface water groundwater supporting irrigated agriculture. accumulates under many semi-arid lands where pumping has lowered levels enough to prevent drainage saline from basin. This paper provides new insights into optimal management pumping, recharge, water, cropping patterns with salinity hydrologic vari...

BACKGROUND The renal distal nephron plays an important role in the maintenance of sodium balance, extra cellular volume and blood pressure. The degree of water transport, via aquaporin2 water channels (AQP2), and sodium transport, via epithelial sodium channels (ENaC) in renal collecting duct principal cells are reflected by the level of urinary excretion of AQP2 (u-AQP2) and the γ-fraction of ...

Vast areas of Western Siberia (about 40%) are occupied by saline soils. Solonetzic agricultural lands mainly used for growing perennial grasses - phytomeliorants. To increase the yield fodder crops on solonetz lands, specialists Siberian Research Institute Fodder Crops in 80s last century developed phytomeliorative crop rotations. The article considers effect grassing rotations with a mixture b...

Quantifying landscape pattern and its change are essential for the monitoring and assessment of environmental consequences of urban area. This paper aims to analyze spatiotemporal patterns of urban landscape changes in Kathmandu Valley, Nepal by combining remote sensing, GIS and landscape metrics. Multi-temporal satellite images from high resolution (CORONA, SPIN and IKONOS) to moderate resolut...

Warm renal ischemia performed during partial nephrectomy has been found to be associated with kidney disease. Since endogenous ouabain (EO) is a neuro-endocrine hormone involved in renal damage, we evaluated the role of EO in renal ischemia-reperfusion injury (IRI). We measured plasma and renal EO variations and markers of glomerular and tubular damage (nephrin, KIM-1, Kidney-Injury-Molecule-1,...

Broxaterol, a new selective beta 2-agonist, has been shown to exert inotropic effects on both fresh and fatigued canine diaphragm. We evaluated the effect of broxaterol on the activation and force output of the respiratory muscles in patients with chronic obstructive pulmonary disease (COPD). We studied 9 patients with moderate to severe COPD. Each patient was infused with saline and Broxaterol...

Gully erosion is one of the most significant erosion types. This type of erosion is one of the most important sources of sediment in different regions of the world. Gullies often have different dimensions and complex characteristics and these characteristics may affect the distribution of vegetation. Topographic characteristics of gullies provide complex ecosystem for vegetation establishment. ...

The present study aimed to investigate the effects of miR-338 on morphine tolerance through the targeting of CXC chemokine receptor-4 (CXCR4) in a rat model of bone cancer pain (BCP). Sprague-Dawley (SD) rats were obtained and divided into model saline (n=10), model morphine (n=50), normal saline (n=10) and normal morphine (healthy rats, n=10) groups. After BCP rat model establishment, the rema...

The occurrence of palygorskite and its formation conditions in soils and sediments were studied along a transect covering granitic hilly lands to marly hilly lands in southern Mashhad. Based on formation conditions, amount and morphology, three kinds of palygorskite including high-amount palygorskite with long fibers in gypsiferous marl and basal part of deep loess deposits with high salinity, ...
