Using immunohistochemistry with antisera raised against the glial fibrillary acidic protein (GFA), we have studied the appearance and distribution of GFA-like immunoreactivity in whole mounts of rodent iris and in sectioned cat and cow iris. In the adult rat iris, a dense plexus of GFA-positive fibers was seen in both the dilator plate and the sphincter. The fluorescent fibers formed large mean...

We present a rare case of traumatic lesion the tibial fibers sciatic nerve with spared peroneal fibers. A 33-year-old victim three month earlier stabbing attack came to our attention gait impairment and weakened left foot plantar flexion internal rotation supination. Based upon clinical signs neurophysiological investigations we suspected that injury had occurred. Ultrasound examination detecte...

AIM Perform a morphometric analysis of the myelinic fibers of the right hypoglossal nerve, in two age groups; to verify quantitative changes as a result of the aging process. STUDY DESIGN Anatomic. MATERIAL AND METHOD A 1 cm fragment of the right hypoglossal nerve was collected from 12 male corpses without any medical history of diseases such as: diabetes, alcoholism, and malignant neoplasi...

Automatic indexing is important for a digital library to provide digitized manuscripts of old document images and their electronic text. As an essential step in creating such a system, this paper discusses the issue of extracting headlines from old newspaper microfilms. Most research on document layout analysis has largely assumed relatively clean images. However microfilm images of old newspap...

Recently, more attentions have been focused on the exploration of hemicelluloses in the paper industry. In this work, xylan-grafted-polyacrylamide (xylan-g-PAM) biopolymers were synthesized by the graft copolymerization of xylan with acrylamide, and their interaction with fibers was also investigated to improve waste newspaper pulp properties with or without cationic fiber fines. The influences...

Resistance artery narrowing and stiffening are key elements in the pathogenesis of essential hypertension, but their origin is not completely understood. In mesenteric resistance arteries (MRA) from spontaneously hypertensive rats (SHR), we have shown that inward remodeling is associated with abnormal elastic fiber organization, leading to smaller fenestrae in the internal elastic lamina. Our c...

Abstract Using rhetorical figures in specialized languages like the language of newspaper headlines is common. The present study attempted to conduct a contrastive analysis of the English and Persian sport newspaper headlines related to the 2014 FIFA World Cup. Toward this end, a corpus consisting of 400 English and 400 Persian headlines published during 12th of June to 13th of July, 2014 was c...

The influence of caloric restriction (CR) initiated at 17 months of age was investigated on selected age-associated measures in skeletal muscle. Tissue from young (3-4 months) ad libitum-fed, old (30-32 months) restricted (35% and 50% CR, designated CR35 and CR50, respectively), and old ad libitum-fed rats (29 months) was studied. CR preserved fiber number and fiber type composition in the vast...
