BACKGROUND Bemisia tabaci (Genn.) (Hemiptera: Aleyrodidae) was observed to have completed its reproductive cycle from the egg to the adult on maize (Zea mays L.). Field and screenhouse studies were carried out to investigate the durability of this putative and unprecedented adaptation to a grass

Because of concern about psoralen-induced phototoxicity and photocarcinogenesis, we investigated the effects of dietary lipids in a mouse model in which 8-methoxypsoralen (8-MOP) and UVA (PUVA) therapy has been shown to be carcinogenic. SKH-Hr-1 hairless albino mice were fed diets containing either

Stimulation of cell-mediated immunity (CMI) by 2,4 dinitrochlorobenzene (DNCB) was reported to be effective in clinical regression of some carcinomas and precancerous lesions. This study investigated development of CMI in rat submaxillary salivary glands with dermal application of DNCB to provide a

We studied the effects of addition of physiological concentrations (0.5 mM) of fatty acids i.e., palmitic (16:0), stearic (18:0), oleic (18:1) and linoleic acid (18:2) on lipoprotein secretion by polarized Caco-2 cells. With saturated fatty acids, secreted lipoproteins were at IDL/LDL density, 1.009

The inhibitory effects of beta-carotene (BC) on preneoplastic lesions induced in male Wistar rats by the resistant hepatocyte model was investigated. Rats were divided into six groups. Initiation was performed in all animals by a single injection of diethylnitrosamine. During the selection/promotion

Omega-3 fatty acids, which are contained in fish oils and certain vegetable oils in contrast to corn oil or safflower oil rich in omega-6 fatty acids (linoteic acid), have been reported to reduce the carcinogenesis in several organs. In this study, the modifying effect of menhaden fish oil was

Dietary fats are known to influence the rate of formation of certain types of chemically-induced and spontaneous tumors. An earlier report indicated dietary fat also plays an important role in predisposition to ultraviolet light (UV)-carcinogenesis. Thus, an examination of the effects of dietary

To investigate the effect of various levels of corn oil and coconut oil on ultraviolet (UV) light-induced skin tumorigenesis and ornithine decarboxylase (ODC) activity, Sencar and SKH-1 mice were fed one of three 15% (weight) fat semipurified diets containing three ratios of corn oil to coconut oil:

Transgenic corn, Zea mays L., hybrids expressing insecticidal proteins from Bacillus thuringiensis (Bt) and non-Bt near isolines were sampled for injury from Helicoverpa zea (Boddie) in North and South Carolina from 2012 to 2017. A total of 7,260 ears were sampled, with an average kernel injury from

After greenhouse and outdoor microplot experiments, a critical density of two third instars per microplot for third instars of European chafer, Rhizotrogus (Amphimallon) majalis (Razoumowsky), in corn, Zea mays L., was derived. On average, the number of missing or damaged plants increased

The purpose of this study was to examine the dose response and time course relationships between PUVA (psoralen + UVA) depletion of skin glutathione (GSH) and the induction of inflammation. Dorsal skin fold thickness (DSFT), an index of cutaneous edema, was used as a noninvasive measure of

beta-Bromo-beta-nitrostyrene is a wide-spectrum biocide most frequently used as a fungicide to combat the formation of slime in paper and pulp mill operations. Toxicity studies were conducted by administering beta-bromo-beta-nitrostyrene (99% pure, trans isomer) to groups of 10 male and 10 female

Ice cream samples were made with a mix composition of 11% milk fat, 11% milk solids-not-fat, 13% sucrose, 3% corn syrup solids (36 dextrose equivalent), 0.28% stabilizer blend, or 0.10% emulsifier and vanilla extract. Mixes were high temperature short time pasteurized at 80 degrees C for 25 s,

Zea mays and Sorghum bicolor are important crops for animal and human nutrition worldwide. In the Central Highland Valley of Mexico, both crops are extremely important, and research is aimed toward increasing yield, disease resistance, and crop adaptation from 1,900- to 2,700-m elevation. In a

The effects of dietary lipid level, degree of saturation, and antioxidant supplements on ultraviolet-light (UV) carcinogenesis were studied in female albino hairless mice. Twelve groups of 42 animals each received a restricted, semipurified, isocaloric diet containing 4%, 12%, or 12% (60%
