In this experimental, effect of some of antifrost on morphology, anatomy content of selective almond cultivars flower buds of 3 late, medium and early flowering cultivars of almond in Pheranshahr region using factorial design base on complete block randomize with 3 replications was investigated. This region is considerate as cold temperate. Experimental trees were planted with 6×6 m in 2000. In...

The peripheral taste system likely maintains a specific relationship between ganglion cells that signal a particular taste quality and taste bud cells responsive to that quality. We have explored a measure of the receptoneural relationship in the mouse. By injecting single fungiform taste buds with lipophilic retrograde neuroanatomical markers, the number of labeled geniculate ganglion cells in...

Application of certain growth regulatinig substanices to the stein and leaves of plants often affects the rate of growth of the terminal and lateral buds. This effect has attracted the attention of many investigators, but up to now vegetative, rather than flower buds, have been studied (2, 3, 8). In general, the application of some of the growth regulating chemicals in relatively high concentra...

The aim is to optimize the isolation of biologically active birch and poplar complexes based on woodworking industry waste study their biological activity create cosmeceutical compositions that have cosmetic pharmaceutical effects.
 Materials methods. object research vegetative organs (buds shoots) (buds). In process work, experimental studies were carried out extraction separation natural...

alveolar echinococcosis (ae), which is caused by ingestion of eggs of the fox tapeworm echinococcus multilocularis , is the most potentially lethal parasitic infection because of its tendency to invade and proliferate in the liver and the difficulty in treatment. this article describes a case of alveolar echinococcosis found in ateles geoffroyi in mashhad, iran. the cysts were characterized as ...

The distribution of substance P (SP)- and calcitonin gene-related peptide (CGRP)-immunoreactive nerve fibers in the taste buds of the epiglottis and aryepiglottic folds was compared between normoxic control and chronically isocapnic hypoxic rats (10% O2 and 3-4% CO2 for 3 months). In the normoxic laryngeal taste buds, SP- and CGRP-immunoreactive fibers were detected within the taste buds, where...

To determine if cold acclimation of sugar maple (Acer saccharum Marsh.) is associated with specific changes in gene expression under natural hardening conditions, we compared bud and root translatable mRNAs of potted maple seedlings after cold acclimation under natural conditions and following spring dehardening. Cold-hardened roots and buds were sampled in January when tissues reached their ma...

The comparative ultrastructural studies of taste buds were made scanning electron microscopically in 15 different kinds of the vertebrtates, such as fish, frog, newt, lizard, snake, chicken, macaw, mouse, rat, guinea pig, rabbit, cat, monkey and human. There were no remarkable differences in the shapes and sizes of the taste pores on the surface ultrastructure of the taste buds among classes an...

Paper birch (Betula papyrifera Marsh.) and three trembling aspen clones (Populus tremuloides Michx.) were studied to determine if alterations in carbon gain in response to an elevated concentration of CO(2) ([CO(2)]) or O(3) ([O(3)]) or a combination of both affected bud size and carbohydrate composition in autumn, and early leaf development in the following spring. The trees were measured for ...
