The host suitability to Ditylenchus destructor of seven common weed species in peanut (Arachis hypogaea) fields in South Africa was determined. Based on the number of nematodes per root unit, white goosefoot (Chenopodium album), feathertop chloris (Chloris virgata), purple nutsedge (Cyperus rotundus), jimson weed (Datura stramonium), goose grass (Eleusine indica), khaki weed (Tagetes minuta), a...

Water and reusable medical device surfaces can be contaminated by natural toxins such as ricin either accidentally or intentionally. This report focuses on the removal of peanut lectin (PL), a ricin surrogate, from water and reusable medical devices and materials. An ELISA assay was used to determine if commercially available water filters could remove peanut lectin from water, and if commercia...

BACKGROUND There are no published data on peanut sensitization in Egypt and the problem of peanut allergy seems underestimated. We sought to screen for peanut sensitization in a group of atopic Egyptian children in relation to their phenotypic manifestations. METHODS We consecutively enrolled 100 allergic children; 2-10 years old (mean 6.5 yr). The study measurements included clinical evaluat...

Peanut protein and its hydrolysate were compared with a view to their use as food additives. The effects of pH, temperature and protein concentration on some of their key physicochemical properties were investigated. Compared with peanut protein, peanut peptides exhibited a significantly higher solubility and significantly lower turbidity at pH values 2-12 and temperature between 30 and 80°C. P...

Peanut allergy is a life-threatening, IgE-mediated allergic disease. In developed countries, the prevalence rate of peanut allergy in school-aged children is reported to be in excess of 1% and continues to rise, representing a major public health concern. Peanut allergy is diagnosed on the basis of a relevant clinical history combined with results of skin-prick testing and/or peanut-specific Ig...

BACKGROUND A diagnosis of peanut allergy has a major impact on an individual's quality of life. Exposure to even small amounts of peanut can trigger serious reactions. Common cleaning agents can easily remove peanut allergen from surfaces such as table tops. Parents of children with peanut allergy frequently ask if peanut allergen can persist on surfaces if they have not been cleaned. OBJECTI...

BACKGROUND Prenatal factors may contribute to the development of peanut allergy. We evaluated the risk of childhood peanut allergy in association with pregnancy exposure to Rh immune globulin, folic acid and ingestion of peanut-containing foods. METHODS We conducted a web-based case-control survey using the Anaphylaxis Canada Registry, a pre-existing database of persons with a history of anap...

BACKGROUND In children, a diagnosis of peanut allergy causes concern about accidental exposure because even small amounts of peanut protein could trigger an allergic reaction. Contamination of toys, books or other items by peanut butter in areas where individuals have eaten may occur in hospital waiting rooms and cafeterias. It is not known if hospital cleaning wipes are effective in removing p...

Peanut allergy is an increasing global health problem, which affects 1--3% of children in Western countries. The prevalence may have tripled in the last 15 years, which constitutes approximately 100,000 new cases annually in the USA and Canada.1--3 The most recent evidence, challenging the current guidelines, highlights the benefits of early introduction of peanuts, rather than avoidance, durin...

The model system between peanut yield and agronomy characteristics which is nonlinear, irreversible and dissipative. The objective in the study was the peanut cultivated in the different ecological regions in Shandong province, aimed to establish the new non-nonlinear model based on Self-Organizing Maps (SOM) to improve the cultivation information of peanut growth process. In the article, apply...
