Drying is one of the processes that present higher costs in food processing. Pre-treatments are often used to reduce drying time and consequently its cost. In the past years, our group has studied the use of ultrasonic pre-treatments to induce structural changes in the fruit tissue as to improve the effective water diffusivity during air-drying and consequently reduce air-drying time. This stud...

objectives: this study was done to assess the some factors which influence on fruit and vegetable consumption among iranian's elderly. methods and materials: this study was a cross sectional study which was done on 400 elderly people through a two stages sampling method. 10 elderly centers were selected from all of elderly centers in tehran. during second stage, a systematic random samplin...

Older male premutation carriers of the FMR1 gene are associated with the risk of developing a late-onset neurodegenerative disorder, fragile X-associated tremor/ataxia syndrome. Although previous postmortem and in vivo magnetic resonance imaging studies have indicated white matter pathology, the regional selectivity of abnormalities, as well as their relationship with molecular variables of the...

Pebrinedisease found to be highly virulent and harm the larval and cocoon characters of tropical tasar silkworm Antheraeamylitta Drury (Daba TV).Therefore an attempt has been made to evaluate the effect of 2% bleaching powder solution in controlling the pebrine disease attained through secondary contamination by studying larval and cocoon characters. In comparison with the healthy control (T1 b...

Ischemically damaged brain can be accompanied by secondary degeneration of associated axonal connections e.g. Wallerian degeneration. Diffusion tensor imaging (DTI) is widely used to investigate axonal injury but the cellular correlates of many of the degenerative changes remain speculative. We investigated the relationship of DTI of directly damaged cerebral cortex and secondary axonal degener...

We have investigated the properties of nerve cell precursors in hydra by analyzing the differentiation and proliferation capacity of interstitial cells in the peduncle of Hydra oligactis, which is a region of active nerve cell differentiation. Our results indicate that about 50% of the interstitial cells in the peduncle can grow rapidly and also give rise to nematocyte precursors when transplan...

BACKGROUND White matter (WM) and grey matter (GM) brain damage in multiple sclerosis (MS) is widespread, but the extent of cerebellar involvement and impact on disability needs to be clarified. OBJECTIVE This study aimed to assess cerebellar WM and GM atrophy and the degree of fibre coherence in the main cerebellar connections, and their contribution to disability in relapsing-remitting MS (R...

INTRODUCTION Many neurologic and psychiatric disorders are thought to be due to, or result in, developmental errors in neuronal cerebellar connectivity. In this connectivity analysis, we studied the developmental time-course of cerebellar peduncle pathways in pediatric and young adult subjects. METHODS A cohort of 80 subjects, newborns to young adults, was studied on a 3T MR system with 30 di...
