Formulas based on protein hydrolysates or free amino acids are used to manage food allergies in infants and young children. Three formula categories are available: Products containing partially hydrolyzed proteins which show some decrease in clinical reactivity but are not recommended for food-allergic infants, formulas based on extensively hydrolyzed proteins that are useful in clinical manage...

Self-reported or explicit loneliness and social support have been inconsistently associated with cardiovascular reactivity (CVR) to stress. The present study aimed to adapt an implicit measure of loneliness, and use it alongside the measures of explicit loneliness and social support, to investigate their correlations with CVR to laboratory stress. Twenty-five female volunteers aged between 18 a...

Introduction: Cerebrovascular reactivity (CVR), defined as a change in cerebral blood flow in response to a vasoactive stimulus, reflects the vasodilatory reserve capacity of cerebral vessels. CVR impairment has shown to be an important prognostic marker of several diseases including stroke. Several techniques have used to measure CVR but the lack of appropriate reproducible stimuli and noninva...

The reactions of chars (or “carbons”) with oxidizing gases are among the most important of industrial reactions. Basic to utilization of any solid fuel, and important in processes ranging from activated carbon production to steel-making, they have been extensively studied for more than a century, e.g., 1,2. It is a tribute to the complexity of the processes involved that they have not yet yield...

We present a new scheme for sensing biomolecules by combining an enzyme hydrogel with a photonic crystal hydrogel layer that responds to ionic strength and pH changes. We demonstrate this unique combination by successfully detecting acetylcholine (ACh) and acetylcholinesterase (AChE) inhibitors. Specifically, the sandwich assembly is composed of layers of photonic crystals and a polyacrylamide ...

Distribution of lactate dehydrogenase (LDH) and succinic dehydrogenase (SDH) in the ovary of mice treated with two chronic doses of sodium fluoride (NaF), for five days, in drinking water. LDH histochemical reactivity was observed following Hess et al., (1958) technique and SDH histochemical reactivity was obtained using the method of Nachlas et al., (1957). A decreasing trend of enzyme reactiv...

Dissolved organic matter (DOM) in 6 water samples collected from 4 surface waters were fractionated using some or all of 5 physicochemical separation processes (activated carbon and XAD-8 batch adsorption, alum coagulation, ultrafiltration (UF), and XAD-8 column fractionation). Activated carbon, XAD-8 batch adsorption and alum coagulation processes fractionated DOM by preferentially removing hi...

relationship to proportion of regulatory T cells. Methods: Forty-five patients with history of systemic symptoms of allergy to Hymenoptera venom were included. Basophil reactivity before the treatment and after one year of allergen immunotherapy (AIT) was measured by CD63 expression, CD203c marker used for basophil identification. Cells were stimulated by aqueous solution of allergen in concent...

The influence of sympathetic nervous activity on cerebral circulation and cerebrovascular CO2 reactivity was investigated by an ƒ¿-adrenergic blockade with phenoxybenzamine (PBZ). Cerebral oxygen and carbon dioxide tension (BrPO2, BrPCO2) and arterial blood pressure were continuously recorded before, during and after intracarotid infusion of 5 mg/kg of PBZ. The effects of 5% CO2 inhalation were...

The primary goal of this pilot feasibility study was to examine the effects of Mindfulness-Oriented Recovery Enhancement (MORE), a behavioral treatment grounded in dual-process models derived from cognitive science, on frontostriatal reward processes among cigarette smokers. Healthy adult (N = 13; mean (SD) age 49 ± 12.2) smokers provided informed consent to participate in a 10-week study testi...
