BACKGROUND Peanut allergy is a life-threatening condition; there is currently no cure. While whole allergen extracts are used for specific immunotherapy for many allergies, they can cause severe reactions and even fatalities in peanut allergy. OBJECTIVE To identify short, HLA-degenerate CD4(+) T cell epitope-based peptides of the major peanut allergen Ara h 1 that target allergen-specific T c...

BACKGROUND Oral immunotherapy (OIT) has shown promise in inducing desensitization for food allergy. However, there are safety concerns regarding the frequency and severity of adverse events during food OIT. OBJECTIVE To evaluate the effect of Ketotifen premedication on adverse reactions during peanut OIT. METHODS A randomized single blind placebo controlled pilot study was performed. Peanut...

Kesmala, T., Jogloy, S., Wongkaew, S., Akkasang, C., and Patanothai, A. Evaluation of ten peanut genotypes for resistance to Peanut bud necrosis virus (PBNV) Songklanakarin J. Sci. Technol., 2006, 28(3) : 459-467 Reactions of peanut genotypes to Peanut bud necrosis virus (PBNV) under sap-inoculation and natural field conditions may be different. Ten peanut genotypes (KK 60-3, KKU 72-1, KKU 72-2...

Peanut is still a major oilseed and staple crop in Senegal. It is, however, prone to contamination by aflatoxins, a major public health concern. This work was conducted to assess aflatoxin contamination risk linked with consumption of peanut-based dietary products and the influence of different cooking processes on aflatoxin fate. A survey made in the markets of Thies (Senegal) showed that the ...

Recent recurrence of Salmonella contamination of peanut butter has become a serious food safety concern for consumers. A study was conducted to identify storage periods and temperature conditions of peanut butter in domestic kitchens and to determine the effects of those storage periods and conditions on survival of Salmonella and Escherichia coli O157:h7. Surveys assessed consumer storage peri...

Whey protein oxygen-barrier coatings on peanuts are not effective, due to incomplete peanut-surface coverage, as well as some cracking and flaking of the coating. Addition of sorbitan laurate (Span 20) in the whey protein coating solution up to the critical micelle concentration (cmc) of 0.05% (w/w) significantly improved coating coverage to 88% of the peanut surface. Increasing the Span 20 con...

Peanut seeds are rich in arginine, an amino acid that has several positive effects on human health. Establishing the genetic variability of arginine content in peanut will be useful for breeding programs that have high arginine as one of their goals. The objective of this study was to evaluate the variation of arginine content, pods/plant, seeds/pod, seed weight, and yield in Valencia peanut ge...

BACKGROUND Peanut allergy is increasing in prevalence due to unknown factors. A growing body of clinical evidence suggests sensitization to peanut occurs through the skin, supported by findings in mouse models. There is a need to identify environmental factors that promote epicutaneous sensitization to peanut. Triclosan is an antimicrobial found in household products that has been associated wi...

studies suggest that children who start solid foods early are at risk for developing food allergies. herein, we evaluated the effects of the introduction of peanuts to the diets of children on emerging peanut allergies. children with allergic rhinitis and asthma were enrolled in the present study and evaluated in four stages. in the first stage, a clinical history was completed for all particip...

Seasonal fluctuations in field populations of Meloidogyne incognita, Pratylenchus zeae, P. brachyurus, Criconemoides ornatus, Trichodorus christiei, and Helicotylenchus dihystera on monocultured corn, cotton, peanut, and soybean were determined monthly for 4 yr. Population densities of M. incognita were greater in corn and cotton plots than in peanut and soybean plots from July until January. T...
