Traumatic brain injury (TBI) is one of the main causes of mortality and morbidity worldwide. Despite extensive investigations over the past few decades, no effective therapies exist to improve the brain function in patients with TBI. Neural tissue engineering is an attractive therapeutic approach to restore the brain structure and function of damaged tissue. Bioactive motif of Stromal cell-deri...

مقدمه: در طول جنگ تحمیلی عراق علیه ایران، بارها از گاز خردل (سولفور موستارد) به عنوان سلاح شیمیایی علیه ایرانیان استفاده گردید. با گذشت سال‌های طولانی از مواجهه با گاز خردل افراد مواجهه یافته هنوز از عوارض دیررس مواجهه شامل مشکلات چشمی، پوستی و ریوی رنج می برند. (SDF-1α (Stromal-Derived Factor 1α  یا CXCL12، کموکاینی است که در مطالعات متعدد، نقش مهم آن در فرآیند رهاشدن سلول های پیش‌ساز و بنیادی...

Background: Restoring bonding composite to silver diamine fluoride (SDF)-treated enamel is challenging. This study investigates if phosphoric acid etch restores bond strength SDF-treated using universal adhesives. Methods: Twenty-four recently extracted permanent teeth were randomly divided into 4 (2 experimental (SDF) and 2 control (CTR)) groups: SDF+Water: SDF (1 min) then water rinse (15 mL)...

This paper describes our system for generating Chinese aspect expressions. In the system, the semantics of different aspects is characterized by specific temporal and conceptual features. The semantic applicability conditions of each individual aspect are theoretically represented by an aspect selection function (ASF). The generation is realized by evaluating implemented inquiries which formall...

objective: transplantation of mesenchymal stem cells (mscs) can promote functional recovery of the brain after hypoxic-ischemic brain damage (hibd). however, the mechanism regulating msc migration to a hypoxic-ischemic lesion is poorly understood. interaction between stromal cell-derived factor-1α (sdf-1α) and its cognate receptor cxc chemokine receptor 4 (cxcr4) is crucial for homing and migra...

Stromal derived factors, SDFs, are a loosely defined group of molecules that may be generated by stromal cells. Two of the stromal derived factors, SDF-1 and SDF-4 belong to the chemokine family. Other SDFs, such as SDF-2 and SDF-5 are not well defined and their biological functions are less known. Although SDF-1 and its receptor have been strongly indicated in the progression of various cancer...

conclusions these results showed that the administration of sdf-1a increases the number of proliferating cells in the injured area in the spinal cord and improves functional recovery. results significant improvements in locomotor function were detected in the sdf-1 group compared with the sci and vehicle groups (p < 0.05). the results showed that sdf-1 treatment increased proliferative cells at...

Semen analysis, sperm DNA fragmentation (SDF) and hypo-osmotic swelling test (HOST) are usually performed for the evaluation of sperm fertilizing ability. There are some debates over the necessity of SDF and HOST incorporation in male infertility work-up.Semen of 77 men was evaluated by SDF and HOST through three semen analyses. Sperm parameters were arranged into different categories: <5%, 5-1...

  U ntreated caries are common findings in low-income communities. Treatment of dental caries in young children is challenging and requires a high skill and high cost of dental anesthesia for control ling patients and thus, chemical methods for arresting dental caries have been proposed. Silver Diamine Fluoride (SDF) is a material that is used to control and to arrest dental caries , especially...
