The predatory mite, Neoseiulus neoagrestis Khaustov and Döker (Acari: Phytoseiidae), recently described as new species for science, but seems to have a great potential be used in biological control. In this study, first step determine the optimum temperature (between three temperatures tested) its mass rearing, we studied characteristics life table parameters fed on Tyrophagus putrescentiae (Sc...
Immature development and reproductive life history of Delphastus catalinae (Horn) (Coleoptera: Coccinellidae) feeding on Bemisia tabaci biotype B (Gennadius) (Homoptera: Aleyrodidae) (= B. argentifolii Bellows and Perring) immatures was studied at three constant temperatures: 22, 26 and 30 degrees C. Lower developmental threshold temperatures (T0) were estimated at 9 and 9.9 degrees C, for male...

To investigate the possibility that mesenchyme can alter the neoplastic properties of an established carcinoma, small (0.5-mm cubes) pieces of the Dunning prostatic adenocarcinoma (DT) were grown in association with seminal vesicle mesenchyme (SVM) for 1 mo. Differentiated DT epithelial cells harvested from the resultant tissue recombinants (rSVM+DT) were recombined with fresh SVM to generate 2...
Possible effects of Chernobyl fallout on outcome of pregnancy in Finland were evaluated in a nationwide follow-up study. The outcomes were the rate of live births and stillbirths, pregnancy loss, and induced abortions by municipality.

BACKGROUND Parasitic infections are prevalent among pregnant women in sub-Saharan Africa. We investigated whether prenatal exposure to malaria and/or helminths affects the pattern of infant immune responses to standard vaccinations against Haemophilus influenzae (Hib), diphtheria (DT), hepatitis B (Hep B) and tetanus toxoid (TT). METHODS AND FINDINGS 450 Kenyan women were tested for malaria, ...
Objective: The aim of this study was to estimate the cheminformatics and qualitative structure-activity relationship (QSAR) of cinnamaldehyde and eugenol. The effects of cinnamaldehyde and eugenol on the viability, doubling time and adipogenic or osteogenic differentiations of human adipose-derived mesenchymal stem cells (hASCs) were also investigated. Materials and Methods: QSAR and toxicity ...
background: despite the large number of papers published on the efficiency of different exogenous gonadotropins, no confirmed protocol exists. therefore, the aim of the present study was to compare the efficacy of 4 exogenous gonadotropins in ivf/icsi cycles. methods: this study, performed from january 2014 to may 2014, recruited 160 women referred to ghadir mother and child hospital and dena h...
