PURPOSE To correlate histopathologic findings from biopsy specimens with their corresponding location within enhancing areas, non-enhancing areas and necrotic areas on contrast enhanced T1-weighted MRI scans (cT1). MATERIALS AND METHODS In 37 patients with newly diagnosed glioblastoma who underwent stereotactic biopsy, we obtained a correlation of 561 1mm3 biopsy specimens with their correspo...

Introduction:  Laser  interstitial  thermotherapy  (LITT)  is  an  internal  ablation  therapy  method  consisting of a percutaneous or intraoperative insertion of laser fibers directly into the liver tumor with  maximum diameter of 5 cm. In this treatment method, there isn’t any general information about the  relationship  between  increasing  the  exposure  power,  coagulation  and  carboniza...

Deep burns of the calvarium due to high-voltage electrical current present serious therapeutic challenges in the healing. In this study, as an alternative approach to the treatment of burned skull, negative pressure dressing is used to facilitate separation of the necrotic bones from healthy margins of the cranium, and to encourage rapid granulation tissue formation after trephination of the bo...

The hypoxic tumor microenvironment is associated with malignant progression and poor treatment response. The glucose transporter Glut-1 is a prognostic factor and putative hypoxia marker. So far, studies of Glut-1 in cancer have utilized conventional immunohistochemical analysis in a series of individual biopsy or surgical specimens. Tissue microarrays, however, provide a rapid, inexpensive mea...

The dissolving effect of the endodontic medicaments calcium hydroxide (Ca(OH)2) and sodium hypochlorite (NaOCl) on necrotic tissue was studied. Pieces of necrotic porcine muscular tissue were placed in either a 0.5% NaOCI solution (Dakin's solution), Ca(OH)2 mixed with water, or a NaOCI solution following pretreatment in Ca(OH)2 for various time intervals. The tissue pieces placed in 0.5% NaOCl...

Regenerative endodontics is a new concept for the management of permanent immature teeth with necrotic pulps. This procedure enables to replace damaged dentine and pulp-dentin complex within root structure healthy tissue. Firstly, elimination clinical symptoms infection then, thickening canal walls continuing maturation finally filled host’s own vital tissue are main goals regenerative endodont...

BACKGROUND Preoperative uterine artery embolization has been shown to help reduce blood loss, with few complications. Most reports indicated that uterine artery embolization is safe for uterine fibrosis; the occurrence of hyperkalemia and acute kidney failure as complications of preoperative uterine artery embolization has not been reported previously. Here we report the occurrence of hyperkale...

BACKGROUND AND PURPOSE MR perfusion-weighted imaging (PWI) has been extensively used to quantify cerebral perfusion deficits after the onset of focal ischemia. The present study tested whether a relative measure of cerebral blood flow such as is obtained with PWI is sufficient to predict irreversible tissue damage following focal cerebral ischemia and reperfusion in the rat suture model. METH...
