The effects of irradiation (0, 1.8, and 4.5 kGy) on the quality of frozen corn and peas were investigated during a 12month period of postirradiation storage at -18 degrees C. Irradiation of frozen corn and peas caused a reduction in ascorbic acid content of both vegetables and a loss of texture in peas but had no significant effects on instrumental color parameters (L*, a*, and b*), carotenoid ...

Primiparous (n = 9) and multiparous (n = 18) Holstein cows averaging 584 +/- 15 kg of body weight (mean +/- SE) were allotted at 2 wk postpartum to nine groups (3 primiparous and 6 multiparous) of 3 cows each to determine the effects of pea extrusion on ruminal degradability and milk production. Cows were fed a total mixed diet based on timothy silage and concentrate for ad libitum intake. The ...

The aim of the present study was to cross-culturally adapt and validate the Spanish version of the Performance Enhancement Attitude Scale (PEAS). A cross-sectional multi-sample survey with 17 independent datasets was carried out. Cross-cultural adaptation of the PEAS into Spanish was conducted through forward/backward translations, consensus panels and comparative analyses of known-groups to es...

Crop traits can alter economically important interactions between plants, pests, and biological control agents. For example, a reduced waxy bloom on the surface of pea plants alters interactions between pea aphids and their natural enemies. In this study, we assess whether the effect of wax reduction extends beyond the 2 or 3 arthropod species closely associated with the plants and into the str...

The effects of dehulling and micronization (infrared heating) on the nutritive value of three cultivars (Impala, Radley, and Sirius) of peas (Pisum sativum) varying in coat color for broiler chickens were studied. Dehulling increased (P < or = 0.05) protein and starch contents and decreased (P < or = 0.05) fiber content of peas. Also, the concentrations of most amino acids slightly increased (P...

This study determined the bioavailability of selenium (Se) from yellow peas and oats harvested from the high-Se soil of South Dakota, United States. The Se concentrations were 13.5 ± 0.2 and 2.5 ± 0.1 mg/kg (dry weight) for peas and oats, respectively. Male weanling Sprague-Dawley rats were depleted of Se by feeding them a 30% Torula yeast-based diet (4.1 μg Se/kg) for 56 days, and then they we...

A novel computer tool (peas@tees), designed to assess habitual physical activity levels in children aged 9 and 10 years, was evaluated. Study 1 investigated agreement between peas@tees and accelerometry in 157 children. Bland-Altman limits of agreement (LOA) revealed peas@tees underestimated physical activity levels compared with accelerometry (bias -21 min; 95% LOA -146-105). Study 2 investiga...

Evidence suggests that the estuarine dinoflagellates, Pfiesteria piscicida Steidinger & Burkholder and P. shumwayae Glasgow & Burkholder, members of the toxic Pfiesteria complex (TPC), may release one or more toxins that kill fish and adversely affect human health. In the current study we investigated the potential for undiagnosed cases of possible estuary-associated syndrome (PEAS), as termed ...

Brenes, A., Rotter, B. A., Marquardt, R. R. and Guenter, W. 1993. The nutritional value of raw, autoclaved and dehulled peas (Piszrz sativum L.) in chicken diets as affected by enzyme supplementation. Can. J. Anim. Sci. 73: 605 614. The effects ofadded crude enzyme preparations, autoclaving and dehulling on the nutritional value of diets containing a low-tannin (Trapper) and high-tannin (Maple)...

Biodegradable poly(ester amide) (PEA) biomaterials derived from α-amino acids, diols, and diacids are promising materials for biomedical applications such as tissue engineering and drug delivery because of their optimized properties and susceptibility for either hydrolytic or enzymatic degradation. The objective of this work was to synthesize and characterize biodegradable PEAs based on the α-a...
