[Development and validation of a nutritional knowledge questionnaire among 9- to 15-year-olds].

Improving nutritional knowledge is a frequent goal in nutritional education programs. However, there is a lack of valid instruments to assess nutritional knowledge in children. Questionnaires on nutritional knowledge are usually related to a specific curriculum or program, and their development or validation process is rarely available.

Comparative effects of sesame seed lignan and flaxseed lignan in reducing the growth of human breast tumors (MCF-7) at high levels of circulating estrogen in athymic mice.

Flaxseed (FS) has a breast tumor-reducing effect, possibly because of its high content of secoisolariciresinol diglucoside (SDG) lignan. Sesame seed (SS) is rich in the lignan sesamin (SES) but is non-protective. Both lignans are metabolized to estrogen-like enterodiol and enterolactone.

Health effects of mixed fruit and vegetable concentrates: a systematic review of the clinical interventions.

Diets rich in fruits and vegetables (FV) have been associated with a reduced risk of chronic disease, including cardiovascular disease. Unfortunately, public health campaigns to increase FV intake have had limited success. A number of mixed concentrated FV products have been studied, which may help certain individuals improve nutrient status.

Repeated, intermittent exposures to diisopropylfluorophosphate in rats: protracted effects on cholinergic markers, nerve growth factor-related proteins, and cognitive function.

Organophosphates (OPs) pose a constant threat to human health due to their widespread use as pesticides and their potential employment in military and terrorist attacks. The acute toxicity of OPs has been extensively studied; however, the consequences of prolonged or repeated exposure to levels of OPs that produce no overt signs of acute toxicity (i.e.

Flaxseed oil reduces the growth of human breast tumors (MCF-7) at high levels of circulating estrogen.

Flaxseed (FS) has been shown to attenuate mammary tumorigenesis, possibly due to its high α-linolenic acid (ALA)-rich oil (FSO) content. This study determined the effect of FSO on the growth of estrogen receptor-positive human breast tumors (MCF-7) in ovariectomized athymic mice at high premenopausal-like estrogen (E2) levels. Mice with established MCF-7 tumors were fed basal diet (control) or basal diet supplemented with FSO (40 g/kg) for 8 wks.
