abstract lettuce is one of the best accumulators of heavy metals and nitrate between leafy vegetables. through this research, it was tried to decreased cadmium absorption with humic acid (ha) and studies the effect of ha on the accumulation and metabolism of nitrate. plants were grown in the peat/perlite and irrigated with hoagland solution with addition of cadmium (2 and 4 mg l -1) and ha (100...

OBJECTIVES A physiological adaptation to a sugar-rich meal is achieved by increased sugar uptake to match dietary load, resulting from a rapid transient translocation of the fructose/glucose GLUT2 transporter to the brush border membrane (BBM) of enterocytes. The aim of this study was to define the contributors and physiological mechanisms controlling intestinal sugar absorption, focusing on th...

The liver is a key organ that responsible for the metabolism of proteins, fats, and carbohydrates absorption storage micronutrients. Unfortunately, prevalence chronic diseases at various stages advancement in world population significant. Due to physiological function liver, its dysfunction can lead malnutrition sarcopenia, patient’s nutritional status an important prognostic factor. This revie...

Iron is an essential trace mineral that plays a number of important physiological roles in humans, including oxygen transport, energy metabolism, and neurotransmitter synthesis. Iron absorption by the proximal small bowel is a critical checkpoint in the maintenance of whole-body iron levels since, unlike most other essential nutrients, no regulated excretory systems exist for iron in humans. Ma...

salinity is one of the most important widespread abiotic stresses which causes toxic and nutritional effects as well as loss of water absorption ability by plants. plants respond to salinity with morphological changes. due to high susceptibility of chickpea to salt stress, some physiological and morphological responses occur following the stress in this plant. thus, different concentrations of ...

There are many changes to the body during pregnancy. Skin care in pregnancy is arguably one of lesser prioritised health topics discussed antenatal – yet it important and here we explore why. The skin covers external surface largest organ, acting as a protective barrier against environmental stressors.1 Other physiological functions include thermoregulation, sensation, water storage, homeostati...

normal 0 false false false en-us x-none ar-sa since its first discovery in an iranian male in 1961, zinc(zn) deficiency in humans is now known to be an important malnutrition problem world-wide. it is more prevalent in areas of high cereal and low animal food consumption. the diet may not necessarily be low in zinc, but its bio-availability plays a major role in its absorption. phytic acid is t...

the interaction between isatin-β-thiosemicarbazone (ibt) and calf thymus dna (ct-dna) was investigated in physiological buffer (ph 7.4) using neutral red (nr) dye as a spectral probe by uv–vis absorption and fluorescence spectroscopy, as well as viscosity measurements. the ibt is stabilized by intercalation in the dna ( k [ibt –dna] =1.03×105 m−1), and displaces the nr dye from the nr–dna comple...
