to investigate the root anatomy and hydraulic conductivity of wheat cultivars, including shiraz, bahar, pishtaz, sistan, and yavaros, a series of controlled environment (growth chamber) experiments were hydroponically conducted at university college of dublin (ucd), ireland in 2010. bahar, pishtaz and sistan cultivars were employed as tolerant to drought and shiraz and yavaros as sensitive. twe...

abstract objective: diabetic peripheral neuropathy (dpn) is one of the most common complications of diabetes. beside the known factors such as hyperglycemia in the pathogenesis of this complication, other etiologies may play role in the pathogenesis of this complication. the aim of this study was the evaluation of the role of serum vitamin d and vitamin b12 levels in this process. material and ...

objective: peripheral arterial disease (pad) is a state characterized by atherosclerotic occlusive disease of lower extremities. diabetes is the main risk factor for pad. material and methods: to assess the prevalence of pad, a cross sectional study was performed on 352 diabetic patients who referred to yazd diabetes research center from 2007 to 2010. vascular assessment was done by measuring t...

PURPOSE To investigate retinotopic functional representation in the visual cortex of mild to moderate primary open-angle glaucoma (POAG) participants and age-matched normal volunteers using high-resolution retinotopic blood oxygenation level dependent (BOLD) functional magnetic resonance imaging (fMRI). METHODS fMRI was performed on 9 POAG participants (61±11 y old) and 9 age-matched controls...

The presence of gap junctions in stratified epithelia has now been extensively documented, but there have been few attempts to quantify them. In the present report, samples of hamster cheek pouch mucosa were processed for electron microscopy and electron micrographs from defined basal, spinous and granular layers were obtained. Using a combination of direct measurement and stereological interse...

The endodermis is a root cell layer common to higher plants and of fundamental importance for root function and nutrient uptake. The endodermis separates outer (peripheral) from inner (central) cell layers by virtue of its Casparian strips, precisely aligned bands of specialized wall material. Here we reveal that the membrane at the Casparian strip is a diffusional barrier between the central a...

Parallel pathways for visual information processing start at the first synapse of the retina, at the cone pedicle. At least eight different types of bipolar cells receive direct synaptic input from an individual cone. The present study explores whether enough synaptic sites are available at the cone pedicle to supply all these bipolar cells. Monkey retinae were optimally fixed for electron micr...

At present, a diffuse discharge plasma of air and other gases at atmospheric pressure is widely used for the surface treatment various materials. However, in many papers it stated that erosion damages occur on flat anodes (targets) as result action. The shape these depends mode. In this study, exposure uniformity was investigated by using nano- micro-sized carbon particles deposited copper anod...

Past attempts to grow human corneal epithelium in culture had limited success, with confluence rarely attained. This work is to determine whether different areas of human corneal epithelium grow better in tissue culture. We compared the extent, the mitotic rates, and morphology of outgrowths and histology of explants from central and peripheral human corneas in culture. Explants, 2 mm in diamet...

We have developed a monoclonal antibody (174H.64) which selectively recognizes antigens shared by the basal cells of mammalian stratified squamous epithelium and squamous cell carcinoma (SCC). Histopathological studies of the frozen tissue sections demonstrated selective binding of this antibody to SCCs of human, bovine, canine, feline, and murine origin. Tumors of other histological types did ...
