A 10-year-old Caucasian boy was referred for evaluation of an acute eruption that had developed over the past 8 days. The began in right popliteal fossa, and then coalesced spread along side his body. fever up to 38°C joint pain were reported 3 days before appearance skin lesions. Physical examination showed erythematous edematous macules papules on hemibody (Figure). left did not show any Labo...

the inheritance of cold resistance was evaluated at the germination stage in crosses between seven rice genotypes as half diallel. analysis of variance indicated that there were highly significant differences among the genotypes, general combining ability (gca) and specific combining ability (sca) for percentage of reduction in radicle length (rl), percentage of reduction in plumule length (pl)...

in sustainable agriculture, using of resistant plants is one of the best methods for integrated pest management. resistance of 140 rice promising lines against striped stem borer was evaluated in two planting date in the field under natural infections in sari agricultural science and natural resources university during 2008-2009. this study carried out as a factorial experiment in randomized co...

the cytoplasmic male sterile (cms) lines that are used in production of hybrid seeds in three-line system often get contaminated with their maintainer lines. using such impure cms lines in rice hybrid seed production lead to un-uniformity and yield loss in hybrid rice. laborious and time consuming phenotypic evaluations are used for elimination of off-type plants in cms multiplication farms. th...

The Oryza sativa L. F8 population derived from a cross between salt tolerance cv. Ahlemi Tarom and salt sensitive cv. Neda was used in the study. Germinated seeds floated on water for 3 d, and after were transferred to float on Yoshida's nutrient solution for 11 d. two weeks after sowing, the seedling was transferred to nutrient solution containing 51.19 mM NaCl (electrical conductivity 6 dSm-1...

Since 1980, when the idea of drug-delivery was proposed, various drug-carriers have been developed, including DNA, proteins, liposomes and several other polymer cages, consisting of many well established natural and synthetic nano-particles. All these drug-carriers can self-assemble in the body and can be manipulated for safer delivery into target tissues. By definition, nano-scale drug deliver...

A new and simple method has been developed for the preparation of -methylene cyclopentenones and presently provides the most convenient route to sarkomycin. The work has, in addition, led to a better understanding of the vinylogous Dieckmann condensation, the course of Michael addition to -methylene cyclopentenones and the behavior of cyclopentenoid endocyclic and exocyclic dienolates towards e...
