Two new resveratrol trimer derivatives, named rheumlhasol A (1) and rheumlhasol B (2) were isolated from the methanolic extract of roots of Rheum lhasaense A. J. Li et P. K. Hsiao together with four known resveratrol dimer derivatives, including maximol A (3), gnetin C (4), ε-viniferin (5), and pallidol (6). The structures were determined by combined spectroscopic methods and by comparison of t...

The cotton plant (Gossypium hirsutum L.) has a very dynamic response to management and changes in the environment that often results in variable and unpredictable yields. Temperature plays a major role in the development of cotton yield. However, limited data are available describing the relationship between high temperature and cotton yield. In this study, it was hypothesized that there are nu...

onychomycosis is a nail disorder associated with aesthetic problems, discomfort, physical injury and loss of dexterity. the purpose of the present study was to isolate and identify the causative fungi of onychomycosis in 2402 patients in kermanshah province, western iran in 1994 to 2010.mycologic assessment was carried out by standard methods including either microscopic or cultural procedures....

Nine sources of resistance to Rotylenchulus reniformis in Gossypium (cotton) were tested by measuring population density (Pf) and root-length density 0 to 122 cm deep. A Pf in the plow layer less than the autumn sample treatment threshold used by consultants was considered the minimum criterion for acceptable resistance, regardless of population density at planting (Pi). Other criteria were amp...

In this study, steam explosion pretreatment was performed in cotton stalks, leading to 5-6 folds enhancements on biomass enzymatic saccharification distinctive in Gossypium barbadense and Gossypium hirsutum species. Sequential 1% H2SO4 pretreatment could further increase biomass digestibility of the steam-exploded stalks, and also cause the highest sugar-ethanol conversion rates probably by rel...

In resource-poor environments, adjustment in plant biomass allocation implies a complex interplay between environmental signals and plant development rather than a delay in plant development alone. To understand how environmental factors influence biomass allocation or the developing phenotype, it is necessary to distinguish the biomass allocations resulting from environmental gradients or onto...

A high density genetic map was constructed using F2 population derived from an interspecific cross of G. hirsutum × G. tomentosum. The map consisted of 3093 marker loci distributed across all the 26 chromosomes and covered 4365.3 cM of cotton genome with an average inter-marker distance of 1.48 cM. The maximum length of chromosome was 218.38 cM and the minimum was 122.09 cM with an average leng...

Demodex spp. was investigated in the 258 university students that participated in the study aimed to investigate Demodex spp. prevalence among university students in Elazig with the methods of cellophane band and standard superficial skin biopsy (SSSB). Of the students, 26 (10.07%) were established as Demodex spp. positive. Demodex spp. prevalence was observed as high among advanced age groups;...
