background: leishmaniasis is a worldwide disease prevalent in tropical and sub tropical coun­tries. many attempts have been made and different strategies have been approached to develop a potent vaccine against leishmania . dna immunisation is a method, which is shown to be effec­tive in leishmania vaccination. leishmania soluble antigen (sla) has also recently been used leishmania vaccination....

abstract various resistances to salinity are due to plants genetically variations, and selection on the basis of one factor will not be a suitable criterion in measurement of resistance to salinity, therefore in choosing resistant varieties, it is necessary to notice to a set of resistant indexes to salinity, creating changes in physiology, anatomy and morphology of plant species. this research...

oxalate soluble pectin (osp) is related to fruit firmness with respect to the chelation of calcium ions with carboxyl groups of adjacent polyuronide chains. this study was carried out to explore the effect of time of fruit harvest, foliar spray with cacl2 during growing season on osp, polygalacturonase activity (pga), fruit firmness and the effects on fruit shelf life, quality and internal ...

kaolin-based film as surround wp® was applied to ‘galaxy’ apple trees to evaluate its effects on postharvest fruit quality. following harvest, the surround wp® on the fruit skin was either wiped off, or left unwiped, then, the fruits from these treatments along with fruits from non-surround wp®-treated trees as the control were stored at 6°c for 100 days. surround wp® film application reduced w...

this study was carried out to investigate impacts of myrobalan rootstock and blackthorn interstem on fruit growth, physico-chemical features and bioactive compounds of two apricot cultivars (‘harcot’ and ‘roksana’) in 2010 and 2011. fruits of both cultivars on myrobalan and/or blackthorn grew with a classic double sigmoid curve from full bloom time to harvest. during growth and development peri...

in our previous work, the effect of use of a water soluble cdi/nhs system as nontoxic cross-linking agent on fabrication of gelatin nanoparticles was investigated. in this research, the effect of variation in some synthetic parameters of gelatin nanoparticles cross-linked by cdi/nhs system such as type of gelatin and formulation of cross- linking agent on their size and distribution was examine...

purpose of this study was to investigate the effect of the presence of the water soluble polymers viz hpmc, pvp and peg 6000 on aqueous solubility and complexation abilities of felodipine with or without presence of β-cyclodextrin (βcd) and hpβcd by phase solubility studies. the data revealed the initial increase in drug solubility followed by plateau in the presence of relatively low polymer c...

BACKGROUND Leishmania-tuberculosis co-infection is not uncommon in clinical practice in East Africa, but little is known about the epidemiology of this problem at population level. A cross-sectional household survey was carried out in an active visceral leishmaniasis (VL) focus in Eastern Sudan in February 2002. METHODS All inhabitants of Marbata village in Atbara River Area, Gedarif State, w...

Molecular methods such as PCR have become attractive tools for diagnosis of cutaneous leishmaniasis (CL), both for their high sensitivity and for their specificity. However, their practical use in routine diagnosis is limited due to the infrastructural requirements and the lack of any standardization. Recently, a simplified and standardized PCR format for molecular detection of Leishmania was d...

The positivities of two methods for the diagnosis of localised cutaneous leishmaniasis (CL) were estimated in 280 patients enrolled in a clinical trial. The trial was conducted in an endemic area of Leishmania (Viannia) braziliensis and trial participants were patients with skin ulcers and positive leishmanin skin tests. Patients underwent aspirative skin punctures of the ulcerated lesions and ...
