One hundred normal fingers were dissected and arthrographs obtained by injection of chromopaque-gelatin mixture, allowing comparison between the radiographic and macroscopic configuration of the synovial capsule. Synovial recesses protruding from each side of every metacarpo-phalangeal joint were found in relation to the collateral ligaments and corresponding exactly with the site of radiologic...

introduction: to recognize the myelinated nerve fibers of the external and extreme capsules in human brain. materials and methods: 10 adult and normal brains (20 hemispheres) from both sexes were studied using 15 mm serial secions in all three cardinal planes after fixation and processing. these sections were stained by klüver – barrera and heidenhin – woelcke methods. results: some fibers from...

PURPOSE To determine the presence of small lesions in the pyramidal tract in patients with amyotrophic lateral sclerosis (ALS) by using magnetization-transfer (MT) measurements and MR imaging. METHODS MT ratios (MTRs) were measured in the posterior limb of the internal capsule in nine patients with ALS and in nine healthy volunteers. RESULTS The mean value of MTRs (%) in patients with ALS w...

In the developing mammalian neocortex, the first postmitotic neurons form the "preplate" superficial to the neuroepithelium. The preplate is later split into a marginal zone (layer 1) and subplate by cortical plate neurons that form layers 2-6. Cortical efferent axons from layers 5 and 6 and cortical afferent axons from thalamus pass between cortex and subcortical structures through the interna...

background: klebseilla pneumoniae causes urinary tract infections, nosocomial pneumonia and intra-abdominal infections. capsular antigens are considered to be the ultimate virulence determinants. among 77 capsular serotypes of k. pneumoniae, serotypes k1 and k2 are the most virulent ones in humans. objectives: we designed a pcr method for detection of capsular serotypes k1 and k2 of k. pneumoni...

Introduction: Injury to the posterolateral corner (PLC) of knee often requires surgical reconstruction. There remains no consensus on treatment for PLC injury, and, therefore, it is imperative have a reproducible injury model improve general knowledge injuries. A novel cadaveric isolated proposed and evaluated using radiographic parameters as well gross dissection. Material methods: All protoco...

Three patients with sporadic amyotrophic lateral sclerosis (ALS) presented with a history of backward falls. Impaired postural reflexes and retropulsion accompanied clinical features of ALS. Hypokinesia, decreased arm swing, and a positive glabellar tap were noted in two of these three patients. Cognitive impairment, tremor, axial rigidity, sphincter dysfunction, nuchal dystonia, dysautonomia, ...

Phalaenopsis is an important genus of orchids that is grown for economical production of cut flower and potted plants. The objective of this study is the evaluation of correlation between morphological and physiological traits of self and cross-pollination of 5 varieties of Phalaenopsis orchid. Some morphological traits were measured: Capsule length (CL), capsule volume (CV), weight of seeds in...

We report an interesting case of a recurrent left lateral neck mass in a 6-year-old boy. When the tumor failed to disappear after a course of antibiotic therapy, it was excised. Histologic study revealed that the encapsulated mass contained a parathyroid gland embedded within a histologically normal thymus. The presence of thymic and parathyroid tissue within a single capsule supports the idea ...
