Background: Acid test meals may improve the accuracy of the C urea breath test (UBT). This has been attributed to changes in gastric emptying rather than to the effects of gastric pH on Helicobacter pylori urease. Aims: To determine whether enhancement of CO2 excretion in the UBT in H pylori infected volunteers by acidification of a test meal is due to a delay in gastric emptying. Methods: Urea...

BACKGROUND Vegetable consumption varies highly across households, based on household structure and socio-economic status, but little is known about the share of fresh vs. processed (e.g. frozen or canned) vegetables. Our aim was to compare the social and economic determinants of fresh and processed vegetable consumption. METHODS We reviewed detailed data on vegetable purchases for at-home con...

A generalized physicochemical model of the response of marine organisms’ calcifying fluids to CO2-induced ocean acidification is proposed. The model is based upon the hypothesis that some marine calcifiers induce calcification by elevating pH, and thus XA, of their calcifying fluid by removing protons (H ). The model is explored through two end-member scenarios: one in which a fixed number of H...

there are many potential risks to human health from heavy metal contamination of vegetables resulting from wastewater irrigated sites. this study was carried out to assess the concentration of chromium (cr) and the risk to human health by chromium through the intake of locally grown vegetables collected from wastewater irrigated agricultural fields. twenty-seven samples of 9 (nine) different ty...

the edible leafy vegetables contain nutritional ingredients that are necessary for human health and it is important that nutrients protection be monitored during processing and storage. the aim of this study was to study some organoleptic attributes of a very popular iranian meal named coco-sabzi, which was prepared with a mixture of edible grinded leafy vegetable pre-stored at different frozen...

the objective of this work was to study the responses of two baby lettuce (lactuca sativa l.) cultivars, namely, green paris island and red sanguine, to different nacl concentrations (0, 5, 10, and 20 mm). the study was conducted in a floating system and plants were harvested at the stage of 5-6 leaves, outside leaf 6-10 cm in length (25 and 31 days after sowing for green and red lettuce, respe...

Fruits and vegetables are universally promoted as healthy. The Dietary Guidelines for Americans 2010 recommend you make one-half of your plate fruits and vegetables. Myplate.gov also supports that one-half the plate should be fruits and vegetables. Fruits and vegetables include a diverse group of plant foods that vary greatly in content of energy and nutrients. Additionally, fruits and vegetabl...

We previously compared infant outcomes between a powdered human milk fortifier (P-HMF) vs. acidified liquid HMF (AL-HMF). A non-acidified liquid HMF (NAL-HMF) is now commercially available. The purpose of this study is to compare growth and outcomes of premature infants receiving P-HMF, AL-HMF or NAL-HMF. An Institutional Review Board (IRB) approved retrospective chart review compared infant ou...
