Optimization of a headspace SPME GC–MS methodology for the analysis of processed almond beverages.
Optimization of a headspace–solid phase microextraction (HS-SPME) technique for analyzing the volatile profile of almond beverages was performed. An ultra-high temperature (UHT)-treated almond beverage prepared at the pilot plant was used as a model for this kind of vegetable beverage. For the analysis a 2-mL almond beverage, aliquot was used in the presence of salt […]
Evaluation of a Self-Administered Computerized Cognitive Battery in an Older Population
Objective: To assess the utility of the Cogstate self-administered computerized neuropsychological battery in a large population of older men. Methods: We invited 7,167 men (mean age: 75 years) from the Health Professionals Follow-up Study, a prospective cohort of male health professionals. We considered individual Cogstate scores and composite scores measuring psychomotor speed and attention, learning […]
Randomized Trial of Peanut Consumption in Infants at Risk for Peanut Allergy
BACKGROUND. The prevalence of peanut allergy among children in Western countries has doubled in the past 10 years, and peanut allergy is becoming apparent in Africa and Asia. We evaluated strategies of peanut consumption and avoidance to determine which strategy is most effective in preventing the development of peanut allergy in infants at high risk for […]
Prevalence of Peanut, Tree Nut, Sesame, and Seafood Allergy in Mexican Adults.
OBJECTIVE: To identify the prevalence of perceived and probable allergic reactions to peanuts, tree nuts, sesame seed, or seafood and its association with the personal history of allergic disease. METHODS: A cross-sectional study was performed in four cities of the metropolitan area of Guadalajara, located in western Mexico. Through sampling by gender and age, 1,126 […]
Effectiveness of superheated steam for inactivation of Escherichia coli O157:H7, Salmonella Typhimurium, Salmonella Enteritidis phage type 30, and Listeria monocytogenes on almonds and pistachios.
This study was undertaken to evaluate the effectiveness of superheated steam (SHS) on the inactivation of Escherichia coli O157:H7, Salmonella Typhimurium, Salmonella Enteritidis phage type (PT) 30 and Listeria monocytogenes on almonds and in-shell pistachios and to determine the effect of superheated steam heating on quality by measuring color and texture changes. Almonds and in-shell […]

Pine nut is a nutrient-rich food with a beneficial impact on human health. The many bioactive constituents of pine nut interact synergistically to affect human physiology in a favorable way. However, pine nut can trigger dangerous allergic reactions. Severe anaphylactic reactions to pine nut accounted for most of the 45 cases reported in the scientific […]
Date (Phoenix dactylifera) Polyphenolics and Other Bioactive Compounds: A Traditional Islamic Remedy's Potential in Prevention of Cell Damage, Cancer Therapeutics and Beyond.
This review analyzes current studies of the therapeutic effects of Phoenix dactylifera, or date palm fruit, on the physiologic system. Specifically, we sought to summarize the effects of its application in preventing cell damage, improving cancer therapeutics and reducing damage caused by conventional chemotherapy. Phoenix dactylifera exhibits potent anti-oxidative properties both in vitro and in […]
Cor a 14 is the superior serological marker for hazelnut allergy in children, independent of concomitant peanut allergy.
BACKGROUND: Hazelnut is the most frequent cause of tree-nut allergy, but up to half of all children with hazelnut allergy additionally suffers from peanut allergy. Our aim was to identify diagnostic values of the most promising serological markers (Cor a 9 and Cor a 14) and to address the influence of concomitant peanut allergy and […]
COR a 14- Specific IgE Predicts symptomatic hazelnut allergy in children.
The self-reported prevalence of tree nut allergy in children has been increasing in the past decade (1). Hazelnuts are in particularly widespread use and this makes them difficult to avoid completely. It is therefore important to correctly diagnose hazelnut allergy to avoid any unjustified diet. The aim of the present study was to assess the […]
A review of oral food challenges in children presenting to a single tertiary centre with perceived or true food allergies.
INTRODUCTION: The prevalence of perceived food allergies exceeds that of true food allergies. Unnecessary food avoidance may increase parental and patient anxiety, reduce quality of life and increase the risk of nutritional deficiency. An oral food challenge (OFC) can provide an objective measure regarding the presence or absence of food allergies in a child. This […]
