drought stress is the most important factor that reduces yield in crops including chickpea and causes some changes in seed composition. this study was performed in order to evaluate the effects of drought stress and starter nitrogen fertilizer on four cultivars of chickpea. experiment was performed in a split-factorial using randomized complete block design with three replications. drought stre...

hemiscorpius lepturus belonging to hemiscorpiidae family is the most venomous of all types of scorpion existing in south west of iran causing hemoglobinuria and dermal lesions by envenomation. we compare the hemolytic pattern upon time in different domestic animals upon time according to their different sphingomyelin contents. in addition other in vitro hematologic parameters, platelet lysis, c...

the major limitation in the application of bioactive molecule is their low permeation across plasma membrane. in 1988 it was discovered, that a natural polycationic protein, the trans-acting activator of transcription (tat) of the human immunodeficiency virus (hiv-1), passed very efficiently through cell membrane of cultured mammalian cells. tat became known as the first cell penetrating peptid...

Skeletal proteins of the red blood cell apparently play an important role in regulating membrane material properties of deformability and stability. However, the role of various intracellular constituents in regulating membrane properties has not been clearly defined. To determine whether Ca2+ and calmodulin might play a role in this regulation, we measured the membrane stability and deformabil...

In the proton exchange membrane fuel cell, (PEM) serves as both main conductor of protons and fuel-blocking membrane. Thus, high conductivity excellent stability are expected for PEMs at same time. According to chemical structure, this review divides PEM into three groups. Recently, high-performance has been made possible by controlling organic–inorganic hybrid composite membranes, nanofiber me...

Carnation (Dianthus caryophyllus L.) is one of the most important cut flowers in the world. Themajority of thecarnation cultivars are sensitive to ethylene which affected the physiological and biochemical postharvest characteristics of these flowers.Applying inhibitors of biosynthesis and action of ethylene is important factor to protect the display quality and extend postharvest life. In order...

background: gallium-66 (t1/2= 9.49 h) is an interesting radionuclide that has potential for positron emission tomography (pet) imaging of biological processes in intermediate to slow target tissue uptake. oxine has been labeled with this radioisotope in the form of [66ga]gallium chloride for its possible diagnostic properties. materials and methods: 66ga was produced in the 30 mev cyclotron (cy...

The objective of this study was to investigate the effect 1/f fluctuation wave on EEG α-α interval and stability cell membrane. We compared analyzed with different character signal slope in healthy men grey rabbits, studied Main outcome measures were gradient increased 142% by electromagnetic field 1.5 β value 135% sound impulse 1/f. After act, erythrocyte membrane osmotic resistance 34~38%. So...
