BACKGROUND Diagnosis of severe peanut allergy is difficult and delays in making an accurate diagnosis may place the patient at risk. Adults with a history of anaphylaxis must strictly avoid any contact with peanuts or products that may contain traces of peanuts. For these persons, conventional evaluations with skin prick testing (SPT) and IgE tests may not be sufficient to assess the risk of an...

BACKGROUND Peanut allergy is an important public health problem in western countries. However, the risk factors associated with this allergy remain uncertain. OBJECTIVE To determine whether the consumption of peanuts during pregnancy and breastfeeding is a risk factor for peanut allergy in infants. METHODS We enrolled 403 infants in a case-control study. The cases were infants aged 18 month...

To evaluate the effect of climate change on peanut production in Northern Iran on the basis of 2oC rise in temperature, a study was conducted using the SSM-Peanut. The simulation was done based on the long-term data obtained from synoptic stations in Guilan including Anzali, Astara, Kiashahr (Astaneh Ashrafieh), Lahijan, Rasht (Agriculture station), Rasht (Airport station), Roudsar and Talesh. ...

The physicochemical and sensory properties of peanut spreads fortified with soy flour were studied. Peanut spreads were replaced by whole soybean flour and soy nut flour at 0, 5, 15, 20 and 30% (w/w). All samples were analyzed for fat, protein, sugar, moisture content, adhesiveness, cohesiveness, hardness and sensory characteristics. Replacing peanut spread with soy flour had significant effect...

Peanut allergy is one of the commonest food hypersensitivities causing fatal or near-fatal reactions. There is, currently, no preventive treatment and the incidence of severe allergic reactions during peanut desensitisation has limited its clinical use. Anti-immunoglobulin E therapy has been shown to be effective in preventing peanut-induced reactions but it does not result in long-term toleran...

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...
