Development of Zoledronic Acid Containing Biomaterials for Enhanced Guided Bone Regeneration.

In recent years, biomaterial-based treatments, also called guided bone regeneration (GBR), which aim to establish a bone regeneration site and prevent the migration of gingival connective tissue and / or peripheral epithelium through the defective area during periodontal surgical procedures have come to the fore. In this report, we have developed a nanoparticle bearing thermosensitive in situ gel formulation of Pluronic F127 and poly(D,L-lactic acid) based membrane to reveal their utilization at GBR by in-vivo applications. In addition, the encouragement of the bone formation in defect area via inhibition of osteoclastic activity is intended by fabrication these biodegradable biomaterials at a lowered Zoledronic Acid (ZA) dose.

Guided bone regeneration by the development of alendronate sodium loaded in-situ gel and membrane formulations.

Biocompatible materials applied in guided bone regeneration are needed to prevent leakage caused by the invasion of peripheral epithelium. (2.1) The aim of this study is to develop a thermosensitive in situ gel system containing alendronate sodium loaded PLGA nanoparticles and alendronate sodium loaded membranes for guided bone regeneration.

Thyrotropinoma with Graves' disease detected by the fusion of indium-111 octreotide scintigraphy and pituitary magnetic resonance imaging.

Thyroid-stimulating hormone-secreting pituitary adenoma (TSHoma) is a rare benign endocrinological tumor which produces TSH in the pituitary gland. Herein, we presented a female patient having TSHoma with Graves' disease during and just after pregnancy that we found by indium-111 octreotide scintigraphy while investigating the patient for hyperthyroidism symptoms.

The critical role of spinal 5-HT7 receptors in opioid and non-opioid type stress-induced analgesia.

The opioid and non-opioid types of stress-induced analgesia have been well defined. One of the non-opioid type involve the endocannabinoid system. We previously reported that the spinal serotonin 7 receptor (5-HT7) blockers inhibit both morphine and cannabinoid-induced analgesia, thus we hypothesized that descending serotonergic pathways-spinal 5-HT7 receptor loop might contribute to stress-induced analgesia.

A new combination therapy in severe acute pancreatitis--hyperbaric oxygen plus 3-aminobenzamide: an experimental study.

Objectives: This study was designed to evaluate effects of hyperbaric oxygen (HBO) plus 3-aminobenzamide (3-AB) cotreatment on tissue oxidative stress parameters (TOSp), tissue histopathology scores (THSc), and bacterial translocations (Bact-Trans) in an experimental model of severe acute pancreatitis (AP).

Methods: Seventy-five Sprague-Dawley rats were randomized into 5 groups. Group 1 received sham.

Bilateral symmetrical subepidermal calcified nodules of the eyelids.

A subepidermal calcified nodule is an uncommon variant of calcinosis cutis and only a limited number of cases have been reported about the eyelid nodules in the literature. A 20-year-old male was referred to our department with symmetrical nodules on both upper eyelids enlarging over 3 years. Both nodules were removed by excisional biopsy.

Isolated relapse of a lymphoblastic leukemia T cell precursor in the epididymis.

A 41-year-old man who had otherwise asymptomatic right scrotal swelling presented to our urology clinic. He had been diagnosed with T cell precursor lymphoblastic leukemia/lymphoma 2 years previously. On examination, his right epididymis was enlarged.

Systemic cannabinoids produce CB₁-mediated antinociception by activation of descending serotonergic pathways that act upon spinal 5-HT(7) and 5-HT(2A) receptors.

Serotonin (5-HT) plays an important role in the descending control of pain. We evaluated the role of descending serotonergic pathways and spinal 5-HT₇ and 5-HT(2A) receptors in comparison to that of 5-HT(1A) and 5-HT₃ receptors in the antinociceptive effects of systemically administered cannabinoids. Antinociceptive effects were evaluated by radiant heat tail-flick and hot plate tests in Balb-C mice.

Prognostic value of GLUT-1 expression in ovarian surface epithelial tumors: a morphometric study.

Objective: To investigate the reported increase in the expression of the glucose transporter GLUT-1 in borderline and malignant ovarian epithelial tumors and its relationship to prognosis.

Study Design: In this study, areas in which immunohistochemical membranous staining with GLUT-1 were most evident were selected, and the proportions of GLUT-1 expression in 46 benign, 11 borderline and 42 malignant cases of ovarian epithelial tumors were determined quantitatively with a computer and Zeiss Vision KS 400 3.0 (Göttingen, Germany) for Windows (Microsoft, Redmond, Washington, U.
