to evaluate the effects of local administration of the fetal brain extract (fbe) on the crushed peripheral nerve, 15 male wistar rats were used. the right sciatic nerve of 10 rats was locally underwent the tense compression for 30 seconds and then randomly divided into experimental and control (sham) groups. the remained rats were considered as intact animals. treatment was commenced weekly, by...

articular cartilage, the load-bearing tissue of the joint, has limited repair and regeneration ability. the scarcity of treatment modalities for large chondral defects has motivated researchers to engineer cartilage tissue constructs that can meet the functional demands of this tissue in vivo. cartilage tissue engineering requires 3 components: cells, scaffold, and environment. owning to their ...

background and aims. furcally-involved teeth present unique challenges to the success of periodontal therapy and influence treatment outcomes. this study aimed to assess to compare use of adm and connective tissue membrane in class ii furcation defect regeneration. materials and methods. 10 patient with 2 bilaterally class ii furcation defects in first and/or second maxilla or man-dibular molar...

objective: to assess the effect of combination of pulsed electromagnetic fields (pemf) with predatory stress on transected sciatic nerve regeneration in rats.  methods: in sham- operated group (sog) the nerve was manipulated and left intact. the 10-mm rat sciatic nerve gap was created in rats. in transected group (transected) nerve stumps were sutured to adjacent muscle and in vein graft group ...

introduction lentil is an important pulse crop in iran. lentil is a seed propagating, self-pollinating crop originating from near east. it is containing 27.5% -31.75% protein and it has high level of iron, calcium, phosphor, thiamin, niacin, and some unusual amino acid as hydroxyarnitin, hydroxyarginin and homo arginin. faostat reported that the world production of lentils was 4,975,621 metric ...

periwinkle (vinca minor l.) is an evergreen perennial herbaceous plant that belongs to the family apocynaceae. the aerial part of this plant contains certain alkaloids such as vincamine, isovincamine and vincine. the most important of these is vincamine that re-duces blood pressure and promotes memory and the ability for mental concentration. mi-cropropagation could be a good alternative for th...

Axon regeneration failure accounts for permanent functional deficits following CNS injury in adult mammals. However, the underlying mechanisms remain elusive. In analyzing axon regeneration in different mutant mouse lines, we discovered that deletion of suppressor of cytokine signaling 3 (SOCS3) in adult retinal ganglion cells (RGCs) promotes robust regeneration of injured optic nerve axons. Th...

The Effect of Caffeine and Ethanol on Flatworm Regeneration by Erica Leighanne Collins Flatworms, or planarian, have a high potential for regeneration and have been used as a model to investigate regeneration and stem cell biology for over a century. Chemicals, temperature, and seasonal factors can influence planarian regeneration. Caffeine and ethanol are two widely used drugs and their effect...

in temperate forests canopy gaps play an important role in driving stand dynamics. the purpose of this research was to compare soil characteristics in forest gaps with several size and its relation to beech regeneration density in lalis forest, chalous. in order to investigate factors, three gap sizes as small gap (200 m2), medium gap (400 m2), and large gap (600 m2) with three replicate were s...
