Abstract Ephyrae are produced through the strobilation of polyps in general life cycle Aurelia coerulea . However, it has been reported that planulae can also metamorphose directly into ephyrae, without passing polyp stage. There is a mixture ephyrae developed from (planula-strobilated ephyrae) and (polyp-strobilated ephyra population. effect planula-strobilated on population yet to be determin...

Two new phenols, 2(S)-2',7-dihydroxy-5,8-dimethoxyflavanone and (S)-2-(4-hydroxyphenyl)-6-methyl-2,3-dihydro-4H-pyran-4-one, were isolated from the ethanol extract of Scutellaria barbata. Their structures were elucidated on the basis of spectroscopic analysis.

The hydro-distilled essential oil from dried aerial parts of one of widespread Iranian skullcaps, Scutellaria pinnatifida A. Hamilt. sap. alpina (Bornm.) Rech. grown in Khorassan province was analyzed by GC and GC/MS. Thirty components were characterized ing 93.8% of the total components detected. The major components of the oil were germacrene-D (39.7%) and beta-caryophyllene (15.0%).

The spontaneous abortion rate in the general population is about 10%. In some women treated with drug regimens for ovulation induction with or without modern assisted reproductive technology (IVF/ICSI etc.) the rate of pregnancy failure is high. Special attention should be directed towards women with recurrent abortion after spontaneous or stimulated cycles without or combined with methods of A...

BACKGROUND Protease inhibitors, particularly ritonavir, causes significant gastrointestinal disturbances such as nausea, even at low doses. This ritonavir-induced nausea could be related to its oxidative stress in the gut. Alleviation of drug-induced nausea is important in effectively increasing patients' compliance and improving their quality of life. Conventional anti-emetic drugs can only pa...

The phylogenetic structure of genus Micromonospora within actinomycetes was examined by analysing the gyrB sequences of 15 validly described species and four subspecies. All but one of the Micromonospora strains formed a tight cluster, as had previously been demonstrated by a 16S rDNA-based phylogenetic analysis. However, the intrageneric relationships deduced from the gyrB-based phylogeny were...
