salinity is one of the major environmental stresses that limit plant growth and productivity. glasswort (salicornia herbacea l.) is one of the native halophytic plants of iran that widely spread in salt areas. the purpose of this study was to determine the physiological and growth responses of s. herbacea to salinity stress. plastic pods (15 cm diameter, 20 cm height) with the silica sand bed w...

objective: gut–brain axis (gba) is very important in creation and modulation of gastrointestinal problems. aloe vera gel has gastroprotective properties. the purpose of this study was to evaluate the effect of aqueous extract of aloe vera leaves on the gastric acid secretion and brain and intestinal water content following acetic acid gastric ulcer induction. materials and methods: gastric ulce...

One of the major challenges of overwintering in the mosquito, Culex pipiens, is prevention of dehydration. In this study, we compare the water balance requirements of nondiapausing and diapausing adult females of C. pipiens. Although their percentage water content is lower, diapausing females contain both higher initial and dry masses than nondiapausing individuals. Both nondiapausing and diapa...

water deficit is an important factor limiting crop production worldwide. drought stress can be managed by improving the availability of soil moisture conserved and selecting drought tolerant genotypes. several physiological indices including stomatal conductance (kl), relative water content (rwc), leaf temperature (tl) and crop temperature stability (cts) along with yield, its components and se...

Mollisols of Santa Fe have different tilth and load support capacity. Despite the importance of these attributes to achieve a sustainable crop production, few information is available. The objectives of this study are i) to assess soil physical indicators related to plant growth and to soil mechanical behavior; and ii) to establish relationships to estimate the impact of soil loading on the soi...

Ground water is highly important source of drinking water in Egypt. Some provinces suffer from high content of iron and manganese in ground water which threat human health. Different processes, such as electrochemical (EC), photo (UV), and combined photo-electrochemical (CPE) methods were used to attain both metals content to the level in accordance to reports of World Health Organization (WHO)...

The effect of ethanol-water media on the synthesis of Ag/TiO2 nanocomposite was investigated with 0.05, 0.1 and 0.5 (wt.%) of Ag content. Ethanol was used as hole-scavenger enhancing the photodecomposition of Ag+ ions under illumination of near-UV light. The nanocomposites were further calcined to 300˚C and 400˚C under controlled atmosphere. The synthesized nanocomposites were tested for photoc...

wilson’s disease (wd) or hepato-lenticular degeneration is a rare autosomal-recessive disorder. a prevalence rate of 30 cases per million and a birth incidence rate of one per 30,000 to 40,000 are often quoted. in 40 to 50% of individuals with wd, hepatic dysfunction is the initial clinical manifestation. with the exception of liver transplantation, treatment of wd is only palliative and intend...
