Hexane, chloroform and ethyl acetate crude extracts of Atalantia monophylla leaf were studied for ovicidal activity against Helicoverpa armigera at 0.5. 1.0, 2.5 and 5.0% concentrations. The ovicidal activity of 67.10% was statistically significant noticed in hexane extract at 5.0% concentration. The least LC50 value of 2.60% was observed in hexane extract with significant Chi-square value at P...

Vinyl chloride (VC) was used as a propellant in a limited percentage of aerosol hairspray products in the United States from approximately 1967 to 1973. The question has arisen whether occupational exposures of hairdressers to VC-containing hairsprays in hair salons were sufficient to increase the risk for developing hepatic angiosarcoma (HAS). Transient two-zone and steady-state three-zone mod...

In August 1995 the development of a new bird repellent, Flight Control containing anthraquinone, was initiated. A series of laboratory formulation testing, cage and pen studies were conducted. The anthraquinone discrimination threshold (concentration at which birds could detect the test material) for starlings (Sturnus vulgaris) was 151 ppm in treated feeds. The model revealed that to achieve 9...

These studies evaluated the effects of inhaled vinyl chloride monomer (VCM) on mouse, rat and rabbit embryonal and fetal development. Groups of pregnant CF-1 mice, Sprague-Dawley rats and New Zealand white rabbits were exposed to 500 ppm VCM for 7 hr daily during the period of major organogenesis. Subsequently, other groups of mice were similarly exposed to 50 ppm VCM, and rats and rabbits were...

Abstract The detection of hydrogen sulfide (H 2 S) is essential because its toxicity and abundance in the environment. Hence, there an urgent requisite to develop a highly sensitive economical H S system. Herein, zinc phthalocyanine (ZnPc) thin film-based K + -exchanged optical waveguide (OWG) gas sensor was developed for by using spin coating. showed excellent sensing performance at room tempe...

Quinolactacide isolated from Penicillium citrinum F 1539 was synthesized and evaluated for its insecticidal activities. The key steps of the total synthesis were an acyl migration reaction of the enol ester intermediate and dehydrogenation of tetrahydroquinolactacide with manganese dioxide. The synthesized quinolactacide showed 100% and 42% mortality against the green peach aphid (Myzus persica...

Aims: Succulents are on the rising trend of popularity due to its compromising behaviour with watering and durability indoors, creating a peaceful healthy living condition. Thus it is need hour find suitable propagation method or use exogenous substances assist regenerating new plants.
 Study Design: The experiment was laid out in randomized block design (RBD) three replications.
 Pla...

We have demonstrated that genistein (GEN) stimulates growth of estrogen-dependent breast tumors in vivo. In this study, we evaluated whether dietary GEN can act in an additive manner with low circulating levels of 17beta-estradiol (E2). We developed an E2 delivery system using silastic implants that yield low circulating plasma E2 levels similar to those observed in postmenopausal women. We ins...

Three practical diets were formulated to contain 0, 500, or 1000 ppm genistein. The three diets were distributed for 1 year to groups of rainbow trout undergoing their first gametogenesis and until spawning. Growth performance of rainbow trout was not affected by dietary treatments. Plasma cholesterol levels were equivalent between groups. In males, a slight but constant induction of vitellogen...

Rimpang temu mangga (Curcuma Valeton Zijp) merupakan tanaman dari keluarga Zingiberaceae. Tanaman ini memiliki kandungan metabolit sekunder antara lain flavonoid, kurkumin, saponin, minyak atsiri, terpenoid dan polifenol. Flavonoid salah satu yang berperan dalam aktivitas antioksidan. Berdasarkan hal tersebut maka penelitian dilakukan untuk mengetahui antioksidan kadar flavonoid rimpang dengan ...
