Functional Role of in the Reproduction of (Hemiptera: Miridae).

Jakovlev (Hemiptera: Miridae) is an omnivorous agricultural pest that has severe economic impacts on a diverse range of agricultural crops. Although the targeted disruption of reproductive development among insects has been proposed as a novel control strategy for pest species, the current understanding of the physiology and molecular mechanisms of reproduction is very limited. In this study, we isolated a putative () gene that is highly expressed in the fat body and ovaries of sexually mature females.

Diet, Sports, and Psychological Stress as Modulators of Breast Cancer Risk: Focus on Methylation.

DNA methylation is influenced by environmental factors and contributes to adverse modification of cancer risk and clinicopathological features. A case-control study (402 newly diagnosed cases, 470 controls) was conducted to evaluate the effect of environmental factors and methylation in peripheral blood leukocyte (PBL) DNA on the risk of breast cancer. A case-only study (373 cases) was designed to evaluate the effects of environmental factors on methylation in tumor tissue and the relationship of methylation with clinicopathological features.

An anti-HBV anthraquinone from aciduric fungus Penicillium sp. OUCMDZ-4736 under low pH stress.

To obtain new bioactive natural products, the effect of acidic stress on the metabolites of an aciduric fungus was investigated. This fungus, Penicillium sp. OUCMDZ-4736, which was isolated from the sediment around roots of mangrove (Acanthus ilicifolius), produced different compounds and higher yields under pH 2.

Photodecolorization of Rhodamine B on tungsten-doped TiO2/activated carbon under visible-light irradiation.

Tungsten-doped TiO(2)/activated carbon catalysts have been prepared by a supercritical-pretreatment-assisted sol-gel process. The structural features of the photocatalysts have been investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV/Vis diffuse-reflectance spectroscopy (DRS), electron dispersive X-ray (EDX), photoluminescence spectroscopy, and Brunauer-Emmett-Teller (BET) analysis. The results revealed that a W-TiO(2) layer was coated on the AC surface, and had higher surface area and smaller crystallite size than TiO(2)/AC obtained by a similar route.

2-(4-Bromo-phen-yl)-N-(2-methoxy-phen-yl)acetamide.

In the title compound, C(15)H(14)BrNO(2), the 4-bromo-phenyl fragment makes a dihedral angle of 76.55 (17)° with the acetamide unit and the dihedral angle between the two benzene rings is 50.88 (14)°.

Bis[1,1-dimethylbiguanide(1-)-kappa2N2,N5]copper(II) monohydrate.

The crystal structure of the title compound, [Cu(C(4)H(10)N(5))(2)].H(2)O, contains two independent copper N,N-dimethylbiguanide complex units, each with square-planar coordination of the Cu atom by four N atoms. The two complexes have different symmetry, with one Cu atom lying on an inversion centre and the other on a twofold rotation axis.
