identifying and selecting superior genotypes in native germplasm is one method for breeding fruit trees. five different ecotypes of jujube (ziziphus jujuba mill.) were collected from different regions of isfahan province, iran, for evaluation of their morphological and pomological traits during 2011-13. results showed that quantitative traits were more significant within ecotypes. ‘‘najafabad’ ...

Ganglion terminale (GT) in its essence displays gathering of pseudounipolar neurons, situated in impressio ganglion trigeminale of the pyramid. Peripheral tentacles of pseudounipolar cells take place in formation of first, second and third reception parts of the third branch of V cerebral nerve and central ones form receptive root entering into middle cerebellar peduncle.

This report describes the clinical and radiological findings of a 48-years-old man suffering from acute impairment of trigeminal sensibility in the left side of his face. This neurological focal symptom started within few weeks after an herpetic oral infection. Brain magnetic resonance imaging showed a single abnormal and ill-defined signal intensity in the left side of pons and middle cerebell...

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...

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...

Well-organized eating and grooming behaviors were elicited in cats by stimulation of a zone in the cerebellum that extended from the fastigial nucleus to the superior cerebellar peduncle. Behaviors appeared to result from the facilitation of specific sensorimotor mechanisms, rather than the induction of generalized "drive" states. The results emphasize the need for a broad view of cerebellar fu...

We applied a single-shot echo-planar axial diffusion tensor sequence with parallel imaging for tractography of the cervical cord. Placing a large region of interest on a reconstructed sagittal image, the cervical cord was depicted as a tract bundle showing color-encoded cephalocaudally. By setting one region of interest in the cerebral peduncle and another in the entire cord on source images, t...

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...

Normal human subjects and patients with lesions of the olivocerebellar system threw balls of clay at a visual target while wearing wedge prism spectacles. Normal subjects initially threw in the direction of prism-bent gaze, but with repeated throws adapted to hit the target. Patients with generalized cerebellar atrophy, inferior olive hypertrophy, or focal infarcts in the distribution of the po...
