The essential oils obtained by hydrodistillation of the unripe and ripe fruits of Alpinia mutica Roxb. and Alpinia latilabris Ridl. were analysed by capillary GC and GC-MS. The oils were principally monoterpenic in nature. The unripe and ripe fruit oils of A. mutica were characterized by camphor (21.0% and 15.8%), camphene (16.6% and 10.2%), β-pinene (8.6% and 13.5%), and trans,trans-farnesol (...
The methanol and fractionated extracts (hexane, ethyl acetate and water) of Alpinia mutica (Zingiberaceae) rhizomes were investigated for their cytotoxic effect against six human carcinoma cell lines, namely KB, MCF7, A549, Caski, HCT116, HT29 and non-human fibroblast cell line (MRC 5) using an in vitro cytotoxicity assay. The ethyl acetate extract possessed high inhibitory effect against KB, M...
Ten compounds isolated from Alpinia mutica Roxb., Curcuma xanthorrhiza Roxb. and Kaempferia rotunda Linn. (Family: Zingiberaceae) were investigated for their platelet-activating factor (PAF) antagonistic activities on rabbit platelets using 3H-PAF as a ligand. Among them, four compounds showed significant inhibitory effects. Alpinetin and 5,6-dehydrokawain isolated from A. mutica exhibited IC50...
This article documents the addition of 92 microsatellite marker loci to the Molecular Ecology Resources Database. Loci were developed for the following species: Anopheles minimus, An. sinensis, An. dirus, Calephelis mutica, Lutjanus kasmira, Murella muralis and Orchestia montagui. These loci were cross-tested on the following species: Calephelis arizonensi, Calephelis borealis, Calephelis nemes...
The evolution of sex determination remains one of the most fascinating enigmas in biology. Transitions between genotypic sex determination (GSD) and temperature-dependent sex determination (TSD) have occurred multiple times during vertebrate evolution, however, the molecular basis and consequences of these transitions in closely related taxa remain unresolved. Here I address a critical question...
Characterizing the molecular network underlying temperature-dependent (TSD) and genotypic (GSD) sex determination, including patterns across closely related taxa, is crucial to elucidate the still enigmatic evolution of sex determining mechanisms in vertebrates. Here we examined the expression of an important gene for sexual differentiation common to both systems, Sf1, at male- and female-produ...
The following seven species of southern African Salticidae, known only from type specimens or one sex, and last described in the early 20th century, are redescribed: Baryphas ahenus Simon, 1902, Brancus muticus Simon, 1902, Euophrys quadrispinosa Lawrence, 1927, Evarcha natalica Simon, 1902, Mogrus macrocephalus Lawrence, 1927, Thyene damarensis Lawrence, 1927 and Thyene bilineata Lawrence, 192...
