abstract various mathematical water uptake models have been introduced for plants response to combined drought and salinity stress. the reduction functions are classified as additive, multiplicative and conceptual models. in this study six different macroscopic reduction functions, namely; van genuchten (additive and multiplicative), dirksen et al., van dam et al, skaggs et al and homaee were e...

Background: Recently, it has been revealed that tyrosine kinase inhibitors (TKIs) act through inducing both oxidative and endoplasmic reticulum (ER) stress in chronic myeloid leukemia cells. However, ER stress signaling triggers both apoptotic and survival processes within cells. Nevertheless, mechanisms by which TKIs avoid the pro-survival effects are not clear. The aim of this study was to ev...

Stress conditioning (e.g., thermal, shear, and tensile stress) of bone cells has been shown to enhance healing. However, prior studies have not investigated whether combined stress could synergistically promote bone regeneration. This study explored the impact of combined thermal and tensile stress on the induction of heat shock proteins (HSPs) and bone-related proteins by a murine preosteoblas...

Water deÞcit and shade stress in weed-infested crops could alter plant growth and biochemistry and feeding and oviposition by the beet armyworm, Spodoptera exiguaHübner. Palmer amaranthpigweed,Amaranthus palmeriS.Wats.,was grownunder 25%of fullwatering(waterdeÞcit), 30% of full light (shade), or combined stress. All treatments decreased plant height andweight. Shade and combined stresses decrea...

There is currently limited knowledge on the role of hormones in plants responses to combinations of abiotic and pathogen stress factors. This study focused on the response of tomato near-isogenic lines (NILs) that carry the Ol-1, ol-2, and Ol-4 loci, conferring resistance to tomato powdery mildew (PM) caused by Oidium neolycopersici, to combined PM and salt stress. These NILs were crossed with ...
