we collected 60 adult males and 85 adult females of trapelus lessonae de filippi, 1863 in early may 2008 from central iranian plateau to study sexual dimorphism in morphological traits as well as female reproductive traits. size-related sexual dimorphism occurred in all the compared body dimensions. the largest female was 83.88 mm in snout-vent length, and the largest male was 73.12 mm. as well...

To study the role of the poly(A) tail length during the replication of poly(A)-containing plus-strand RNA virus, we have developed a simple reverse transcription polymerase chain reaction (RT-PCR)-based method that substantially improves the previously reported PAT [poly(A) test] assay. In contrast to the PAT assay, the new method is based on the enzymatic 3' elongation of mRNA with guanosine r...

BACKGROUND The study on phytochemical difference between red and black goji berry is limited. METHODS Antioxidant activities and phenolic profiles in terms of total phenol content, total flavonoid contents, condensed tannin content, monomeric anthocyanin content, and total carotenoid content of red goji berry (Lycium barbarum) and black goji berry (L. ruthenicum) were compared using colorimet...

To clarify genotoxic effects of occupational exposure to antineoplastic drugs in Japan, we examined DNA damage, assessed by the comet assay, in 121 female nurses and 46 female clerks working at three hospitals in the northeast of Japan. The comet assay is considered to be a sensitive and rapid method for DNA strand break detection in individual cells, and tail length and tail moment are used as...
