the  present study was aimed  at comparing the ability of three crop plants for phytoremediation of zinc (zn) and nickel (zn) from soils. a factorial (3×2×3) experiment based on rcbd was  used to compare the treatments,  and was repeated three times. the first factor was crop type (wheat, clover and rapeseed), the second factor was heavy metal types (zinc (zn) and nickel (ni)) and the third fac...

objectives: fluoride therapy is important for control and prevention of dental caries. laser irradiation can increase fluoride uptake especially when combined with topical fluoride application. the objective of this study was to compare the effects of co 2 and diode lasers on enamel fluoride uptake in primary teeth. materials and methods: forty human primary molars were randomly assigned to fou...

the interaction between sodium and calcium, magnesium and calcium and the combined effect of sodium, magnesium and calcium was observed on the growth and ion uptake of hippophae rhamnoides l. the results demonstrated that an addition of sodium with calcium, (set a, na 2.5 + ca 5 mm) showed prominent increase in fresh weight of roots and shoots. the dry weight (average) of roots decreased and th...

background: phytoremediation is one of the methods used to remove contaminants and while being simple, cheap and efficient, does not cause environmental deterioration. the aims of this study were phytoremediation of soil contaminated by cd, the simultaneous survey of the influence of different electrical conductivity values, and comparison of two soil amendments including sludge and municipal c...

Unilateral condylar hyperplasia is the main cause of mandibular asymmetry. Radionuclide bone scanning is a useful procedure for functional evaluation of temporomandibular joint. In this study, 39 patients with normal bone scan and no facial asymmetry were studied. All patients were below 22 years of age. Normal condylar uptake was determined in this group of patients. Right & left condyla...

the objective of this study was to evaluate the effect of process conditions and different pretreatments including ultrasound, microwave and osmotic dehydration on mass transfer and oil uptake during deep fat frying of potato slices. ultrasound pretreatment was performed at frequency of 40 khz for 10 and 30 minutes, microwave pretreatment was conducted at 5 w/g power and osmotic dehydration pre...

the aim of this study was the better assessment of the relationship of pulsing treatment of gibberellic acid as an anti-senescence agent and holding in sucrose as a carbohydrate supply resource on improving some qualitative and physiological attributes of cut rose flower cv. velvet. hence, an experiment involving the pulsing treatment with gibberllic acid (ga3) at 0, 20, 40 and 60 mg l-1, for 2...

objective(s): iodine-123 metaiodobenzylguanidine (123i-mibg) myocardial scintigraphy has been used to evaluate cardiac sympathetic denervation in lewy body disease (lbd), including parkinson’s disease (pd) and dementia with lewy bodies (dlb). the heart-tomediastinum ratio (h/m) in pd and dlb is significantly lower than that in parkinson’s plus syndromes and alzheimer’s disease. although this ra...

the present study is aimed at assessing the ability of   pseudomonas sp. an29 to uptake hg2+ from the metal contaminated environment. the minimum inhibitory concentration (mics) of hg   2+ was 500 μg/ml. pseudomonas   sp. an29 could tolerate pb   2+ (600 g/ml), cu2+ (200 g/ml), cd2+ (50 g/ml), zn2+ (50 g/ml), ni2+ (550 g/ml) and cr   6+ (150 g/ml). the isolate showed typical g...

background: premature ejaculation (pe) is the most common sexual disorder in men and studies reported prevalence up to 30% (1, 2). pe is not a life-threatening medical condition but it influences the quality of life (qol). objectives the aim of this study was to compare the efficiency, and safety of alpha blocker drugs in the treatment of patients with premature ejaculation (pe). additionally w...
