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...

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;...

The present study aimed to 1) determine the colonization rates of medically important Trichosporon species on normal perigenital skin and 2) determine the isolation rates of Trichosporon spp. isolated from the urine and catheters of Brazilian patients hospitalized in the Intensive Care Unit (ICU). The overall colonization rate of Trichosporon spp. was 11.15% (112 isolates). The most common spec...

"Upper limits of normal" antistreptolysin O (ASO) and antideoxyribonuclease (ADN) B titers were determined on serum specimens from various age groups of pediatric patients with no history of a recent streptococcal infection and on healthy adult hospital employees. The upper limit of normal value is that level of antibody titer exceeded by no more than 15% of the total subjects in each age group...

Abstract A total of 4512 rhizobacteria were isolated at three stages of plant growth from Achillea ageratum colonizing a polluted site with an antimony concentration gradient. For 222 of these isolates auxin production (aux(+)) was verified in vitro. The percentage of aux(+) isolates increased with soil antimony concentration, as well as with plant growth stage. An amplified rDNA restriction an...

Achillea (Asteraceae) comprises 115 species, which are mainly distributed in Europe, Asia, and North Africa and as an introduced plant in the New World. The genus Achillea, generally called Bumadaran in Persian, is well known for medicinal properties such as anthelmintic, anti-inflammatory and anti-microbial effects.
