Triclad flatworms are well studied for their regenerative properties, yet little is known about their embryonic development. We here describe the embryonic development of the triclad Schmidtea polychroa, using histological and... more
The purpose of this work was to evaluate the in vitro virulence of three isolates of Metarhizium anisopliae var. anisopliae to eggs and larvae of the tick Boophilus microplus. The fungus tested was isolated from engorged females of B.... more
Aqueous leaf extract of Ricinus communis L (Euphorbiaceae), a cultivated plant in tropical countries, showed excellent insecticidal activity against Callosobruchus chinensis L (Coleoptera: Bruchidae). We have isolated and tested... more
Two fractions showing proteolytic enzymes have been obtained from the latex of Synadenium grantii Hook, ‘f’, using gel-filtration and anion-exchange chromatographic techniques. Both these proteases have the same molecular mass of 76±2 kDa... more
Presenting in her late twenties, this case report examines a G6P2 patient at 11-weeks gestation that was diagnosed with a blighted ovum, as well as the subsequent outcome and methods of additional management. A blighted ovum refers to a... more
Background, aim and scope The biocide triclosan (TCS) is commonly used in personal care, acrylic, plastic, and textiles products. TCS has been detected in surface water in several countries, and its ecological impact is largely unknown.... more
The present investigation demonstrates establishment of United Nations Environment Programme (UNEP) priority Persistent Organic Pollutants (POPs) using high-resolution gas chromatography–high-resolution mass spectrometry. Particularly,... more
Avian egg shape is generally explained as an adaptation to life history, yet we currently lack a global synthesis of how egg-shape differences arise and evolve. Here, we apply morphometric, mechanistic, and macroevolutionary analyses to... more
This article first examines the events occurring in male and female genital tracts, which prepare human sperm to encounter the egg. Central is a glycoprotein, gp20, homologous to the leukocyte antigen CD52. This protein is secreted in the... more
The specificity of early sperm-zona interactions in vitro was studied using gametes from the mouse, rabbit, pig, and human. Mouse epididymal spermatozoa, capacitated in vitro, bound to the zonae of intact mouse oocytes and zona fragments... more
