Anticancer, antimicrobial, insecticidal and molecular docking of sarcotrocheliol and cholesterol from the marine soft coral Sarcophyton Trocheliophorum.

The anticancer, antimicrobial, and insecticidal activities of sarcotrocheliol (1) and cholesterol (2) obtained from the soft coral Sarcophyton trocheliophorum (S. trocheliophorum) were intensively studied. According to this study, both compounds 1 and 2 showed potential cytotoxicity towards the human colorectal carcinomaHCT-116 (IC 10.

Surf Redfish-Based ZnO-NPs and Their Biological Activity with Reference to Their Non-Target Toxicity.

The marine environment is a rich source of bioactive compounds. Therefore, the sea cucumber was isolated from the Red Sea at the Al-Ain Al-Sokhna coast and it was identified as surf redfish (). The aqueous extract of the surf redfish was utilized as an ecofriendly, novel and sustainable approach to fabricate zinc oxide nanoparticles (ZnO-NPs).

Mosquitocidal Activity of the Methanolic Extract of and Its Isolated Compounds against , and Their Impact on the Non-Target Organism Zebrafish, .

In this study, the crude extract and its isolated compounds from the stem bark of Annickia chlorantha were tested for their larvicidal, developmental, and repellent activity against the mosquito vector, Culex pipiens, besides their toxicity to the non-target aquatic organism, the zebrafish (Danio rerio). The acute larvicidal activity of isolated compounds; namely, palmatine, jatrorrhizine, columbamine, β-sitosterol, and Annickia chlorantha methanolic extract (AC), was observed. Developmentally, the larval duration was significantly prolonged when palmatine and β-sitosterol were applied, whereas the pupal duration was significantly prolonged for almost all treatments except palmatine and jatrorrhizine, where it shortened from those in the control.

Impact of paternal transmission of gamma radiation on reproduction, oogenesis, and spermatogenesis of the housefly, L. (Diptera: Muscidae).

Purpose: This study aimed to investigate the impact of gamma radiation of males (resulted from irradiated pupae) crossed with unirradiated females on fecundity, egg hatchability, adult emergence, sex ratio, sterility, in addition to reproductive development at the level of oogenesis and spermatogenesis compared to unirradiated group.

Material And Methods: The housefly, pupae were exposed to three sublethal doses of 5, 10, and 15 Gy.

Results: Fecundity was severely reduced particularly in F2 (11.

Impact of gamma irradiation on the development and reproduction of Culex pipiens (Diptera; Culicidae).

Purpose: The aim was to evaluate the effects of irradiation of Culex pipiens irradiated as pupae on the larval and pupal mortality percentages, the larval and pupal duration, adult emergence percentages and ovarian development in comparison with the un-irradiated group.

Material And Methods: The mosquito, C. pipiens Linnaeus (L) was irradiated as pupae with three gamma doses 40, 60 and 80 Gy.

Toxicity of some plant extracts against vector of lymphatic filariasis, Culex pipiens.

Many insecticides are generally used as larvicides to control Culex pipiens, vector of lymphatic filariasis. This study was undertaken to evaluate the larvicidal activity of some potential larvicidal plants extracts against C. pipiens larvae.

Effects of midgut bacteria and two protease inhibitors on the transmission of Wuchereria bancrofti by the mosquito vector, Culex pipiens.

Laboratory investigations were carried out to study the effect of two protease inhibitors on the transmission of W. bancrofti filarial by Culex pipiens and to study the susceptibility interaction between filaria and protease inhibitors. The results obtained revealed that, infection rates were variable among untreated and treated symbiotic and aposymbiotic Cx.

Effects of midgut bacteria and two protease inhibitors on the reproductive potential and midgut enzymes of Culex pipiens infected with Wuchereria bancrofti.

Laboratory investigations were carried out to asses the effect of some proteases inhibitors on the reproductive potential of Culex pipiens females resulted from larvae treated with different protease inhibitors. The fecundity and engorgement of symbiotic and aposymbiotic C. pipiens females were significantly reduced.
