With the growing number of children and young people with complex care needs or life-limiting conditions, alternative routes for nutrition have been established (such as gastrostomy feeding). The conditions of children and young people who require such feeding are diverse but could relate to problems with swallowing (dysphagia), digestive disorders or neurological/muscular disorders. However, the use of a blended diet as an alternative to prescribed formula feeds for children fed via a gastrostomy is a contentious issue for clinicians and researchers...

Herbivores emit plant-associated volatile organic compounds (VOCs) after feeding on plants. These plant-associated VOCs can be used by parasitoids to locate their hosts. It is hypothesized that certain compounds play key roles in the attractiveness of host-associated odor blends. The larval parasitoid, Microplitis croceipes (Hymenoptera: Braconidae) and its herbivore host, Heliothis virescens (Lepidoptera: Noctuidae), a major pest of cotton plant were used as model species to identify key compounds mediating attraction of parasitoids to hosts...

A blenderized tube feeding (BTF) is a mixture of food and liquid that is pureed and administered through a feeding tube. This method of providing nourishment has been used for millenniums. In fact, it could be viewed as the original form of nutrition support. However, over time, the role of BTF has changed. Initially, it was the only method of nourishing a patient who could not sustain himself or herself on oral feeds. With the development of commercial formulas in the mid-20th century, the usage of this feeding modality declined drastically due to the nutrition precision, ease, and sterility of commercial formulas...

Epilachna vigintioctopunctata Fabr. (Coleoptera: Coccinellidae) and Aulacophora foveicollis Lucas (Coleoptera: Chrysomelidae) are important pests of Solena amplexicaulis (Lam.) Gandhi (Cucurbitaceae), commonly known as creeping cucumber. The profiles of volatile organic compounds from undamaged plants, plants after 48 hr continuous feeding of adult females of either E. vigintioctopunctata or A. foveicollis, by adults of both species, and after mechanical damaging were identified and quantified by GC-MS and GC-FID analyses...

Due to concerns related primarily to allergic response and malabsorption, enteral nutrition therapy has traditionally relied on the use of elemental formulas in children with intestinal failure (IF). Blended food diets via a gastrostomy tube have been reported to improve feeding tolerance in pediatric populations receiving long-term enteral nutrition therapy. Complex macronutrients have been shown to stimulate intestinal adaptation in animal models. We report on our experience in children with IF who had an overall improvement in stool output when transitioned from an elemental formula to a tube feeding formula with real food ingredients (TFRF)...

BACKGROUND: Enteral tube misconnections resulting in enteral nutrition being provided into the wrong port or tube has been increasingly reported, prompting the development of new international design standards for medical device tubing connectors. METHODS: Four sample enteral feeds with varying viscosity were placed into a syringe with either the current feeding connector or a prototype ENFit connector. The force (N) required to compress the syringe was gathered through a dynamic mechanical analyzer (RSA G2 Solids Analyzer; TA Instruments)...

BACKGROUND: Families of children requiring nutrition support may be interested in providing blenderized food by gastrostomy tube (BFGT). Some registered dietitians (RDs) recommend partial or full BFGT for children with tube feeding intolerance who are unresponsive to standard interventions. There is little published information on the safety and efficacy of BFGT feeding. The purpose of this survey was to elicit experiences of pediatric RDs with BFGT in clinical practices. METHODS: A survey instrument was distributed to members of the Pediatric Nutrition Practice Group to report experiences of BFGT in clinical practice...

A blended diet for enteral nutrition is defined as home-made everyday food blended to a smooth 'single cream' consistency. At present, blended food is not recommended as a first choice. However, the wishes of parents who prefer to use blended food for their child need to be respected, and hospice policy for Children's Hospice South West is to replicate home conditions as far as possible. Therefore guidelines have been created for use of a blended diet. However, benefits in physical and emotional health need to be balanced against risks of tube blockage, contamination and digestive upsets...

Human skin emanations attract hungry female mosquitoes toward their host for blood feeding. In this study, we report the flight orientation and electroantennogram response of Aedes albopictus females to certain unsaturated acids and alcohols found in human skin. In the Y-tube olfactometer, odors of lactic acid and 2-methyl-3-pentanol attracted 54-65% of Ae. albopictus females at all doses in a dose-dependent manner. However, at the highest dose (10(-2) g), the acids repelled 40-45% females. Attractancy (ca...

BACKGROUND: The gastric accumulation of enteral formulas in tube-fed patients leads to an increased risk of vomiting and regurgitation. Gastric secretion-induced coagulation of proteins in enteral formulas might lead to gastric accumulation of solid protein particles that further increase the risk of upper digestive intolerance. This study used magnetic resonance imaging to noninvasively assess the half-emptying time (t50) of enteral formulas differing in protein composition. METHODS: Three isocaloric (450 kcal) and isovolumetric (300 mL) enteral formulas, 1 with a noncoagulating P4 protein blend and 2 with coagulating casein-dominant protein blends, were compared in a double-blind, randomized, 3-way crossover study in 21 healthy volunteers...

Plant diversity is known to affect success of host location by pest insects, but its effect on olfactory orientation of non-pest insect species has hardly been addressed. First, we tested in laboratory experiments the hypothesis that non-host plants, which increase odour complexity in habitats, affect the host location ability of herbivores and parasitoids. Furthermore, we recorded field data of plant diversity in addition to herbivore and parasitoid abundance at 77 grassland sites in three different regions in Germany in order to elucidate whether our laboratory results reflect the field situation...

Engineered grafts are still needed for small diameter blood vessels reconstruction. Ideal materials would prevent thrombosis and intimal hyperplasia by displaying hemocompatibility and mechanical properties close to those of native vessels. In this study, poly(vinyl alcohol) (PVA)/gelatin blends were investigated as a potential vascular support scaffold. We modified a chemically crosslinked PVA hydrogel by incorporation of gelatin to improve endothelial cell attachment with a single-step method. A series of crosslinked PVA/gelatin films with specific ratios set at 100:0, 99:1, 95:5, and 90:10 (w/w) were prepared and their mechanical properties were examined by uniaxial tensile testing...

The plant semiochemical cis-jasmone primes/induces plant resistance that deters herbivores and attracts natural enemies. We studied the induction of volatile organic compounds (VOCs) in winter wheat and spring barley after exposure of plants to three synthetic cis-jasmone doses (50 μl of 1, 100, and 1 × 10(4) ng μl(-1)) and durations of exposure (1, 3, and 6 h). Cereal leaf beetle, Oulema melanopus, adult behavioral responses were examined in a Y-tube olfactometer to cis-jasmone induced plant VOC bouquets and to two synthetic blends of VOCs (3 green leaf volatiles (GLVs); 4 terpenes + indole)...

Fatty acid (FA) profile is a critical factor in the nutritional properties of fats, but, stereochemistry may also play a fundamental role in the rate and extent to which FAs are absorbed and become available. To better understand this phenomenon, we evaluated the bioavailability of FAs in linseed-oil and palm-stearin blends compared to their interesterified mix, using a sn-1,3 stereospecific lipase, to determine if there was any difference in terms of FA availability when using this technology. Test meals were fed through an intragastric feeding tube on Sprague-Dawley male rats after 18 h fasting...

Herbivore-induced plant volatiles are important host finding cues for larval parasitoids, and similarly, insect oviposition might elicit the release of plant volatiles functioning as host finding cues for egg parasitoids. We hypothesized that egg parasitoids also might utilize HIPVs of emerging larvae to locate plants with host eggs. We, therefore, assessed the olfactory response of two egg parasitoids, a generalist, Trichogramma pretiosum (Tricogrammatidae), and a specialist, Telenomus remus (Scelionidae) to HIPVs...

We report large induction (>65(fold) increases) of volatile organic compounds (VOCs) emitted from a single leaf of the invasive weed mossy sorrel, Rumex confertus Willd. (Polygonaceae), by herbivory of the dock leaf beetle, Gastrophysa polygoni L. (Coleoptera: Chrysomelidae). The R. confertus VOC blend induced by G. polygoni herbivory included two green leaf volatiles ((Z)-3-hexenal, (Z)-3-hexen-1-yl acetate) and three terpenes (linalool, ß-caryophyllene, (E)-ß-farnesene). Uninjured leaves produced small constitutive amounts of the GLVs and barely detectable amounts of the terpenes...

BACKGROUND: There is currently a lack of clinical data on fibre requirements in UK children. Subsequently, the ideal fibre profile for enteral formulae designed to meet the requirements of older children is unknown. The present study aimed to investigate the effect of fibre supplementation on gastrointestinal function of children aged 7-12 years (or weight 21-45 kg) receiving an age-specific high-energy enteral feed. METHODS: In this double-blind randomised crossover study, 25 home enterally tube-fed children with a range of medical conditions (including cystic fibrosis, neurological conditions, liver transplant and bone marrow transplant) were given a 1...

Decompensated cicatrices stricture of upper alimentary canal is a complex disease clinically presenting a high mechanical blocking and leads to expressed abnormality of homeostasis, which requires its pathogenetic correction of urgency evidence. The greatest difficulty is correct protein-energy malnutrition and water-electrolyte metabolism. Prior to the imposition of stoma for feeding should begin immediately with standard parenteral nutrition solutions. In a subsequent it is nessesary to resort more physiologecal tube alimentasion...
