Food hoarding plays an important role in the energetic repertoire of a variety of mammalian species. Both food hoarding and food intake have been examined in rodents using several energetic challenges including food deprivation, treatment with metabolic fuel blockers, and enhancement of fuel storage. In the present experiment, we examined food hoarding by female jirds (Meriones shawi), a desert...

Cold-acclimation of rats (3 weeks, 4 degrees C) had no effect on basal rates of glucose production or utilization. Under euglycaemic-clamp conditions, in which the circulating insulin concentration was increased by approx. 50 microunits/ml, cold-acclimated rats showed a greater increase in glucose utilization and a greater suppression of endogenous glucose production. Tissue sites of glucose ut...

Two persons with severe intellectual disabilities and two persons with profound intellectual disabilities were repeatedly presented with five different pairs of food items. The five pairs of items represented different degrees of preference, from highest to lowest. Happiness indices were monitored from the time that a pair of items was presented until a choice was made. Surprisingly, participan...

OBJECTIVE To examine the association between dietary patterns and obesity indices (BMI, WC, WHR) among Tehranian adults in a 6-year follow-up study. METHODS Within frame of a cohort study in Tehran (mean follow up 6.6+/-0.9 years), 141 adults were recruited with: two 24 hour dietary recalls at the beginning, as well as obesity indices at the beginning and end of the study period. Dietary inta...

AIM In this study, we conducted a dietary assessment of the subjects and investigated the relationship of energy, nutrients and food intake to the indices of masticatory ability and masticatory behavior for identifying the differences in their association with dietary patterns. METHODS The subjects were 61 5-y-old children, of whom 45 were included in the final analysis. Occlusal force was me...

The increasing need for food can be met through an increase in crop productivity and reduction in pest associated losses. Recombinant DNA technology has created new avenues for genetic enhancement of crops through the development of transgenic plants with resistance to insects. Bacillus thuringiensis (Bt) genes have been widely used as candidate genes for genetic transformation of crop plants f...

Background: Knowledge regarding distribution and determinants of household food insecurity focusing on vulnerable groups is utmost important for ensuring food security, which is every nation prime agenda. This study was conducted to determine the prevalence and determinants of household food insecurity among the tribal population of Purulia, West Bengal. Methods: A cross-sectional study was car...

BACKGROUND Food security is a multi-dimensional phenomenon. The objective of this study was to identify and prioritize major indices for determining food insecurity in Iran. METHODS Descriptive study using the Delphi method was conducted through an email-delivered questionnaire. Forty-three senior experts at national or provincial level were selected based on their work experience and educati...

The goal of any clustering algorithm is to find the optimal clustering solution with the optimal number of clusters. In order to evaluate a clustering solution, a number of validity indices are used during or at the end of a clustering process. They can be internal, external or relative. In this paper, we provide two main contributions: First, we present an experimental study comparing the majo...

desertification could be traced back to one or many factors. thus, to cope with such a phenomenon, there exists a need for a profound understanding of the processes and the causes. the study area of the current paper is the extent of shahrekord’s marghzar as an important case amongst the important ones of the province. in order to evaluate the roots of desertification in the area, the iranian m...
