Histopathological evaluation of the effect of locally administered strontium on healing time in mandibular fractures: An experimental study.

Background: Mandibular fractures are the most common facial fractures. They can be treated by conservative techniques or by surgery. The authors hypothesized that the application of a single local dose of strontium chloride would accelerate the healing of subcondylar mandibular fractures, shorten the recovery time and prevent complications.

Chordoid Meningioma - A Case Report: Clinicopathological Features and Differential Diagnosis of an Uncommon Tumor.

Meningiomas are tumors that originate from the arachnoid cell and the majority are benign and grade I tumors according to World Health Organization. Chordoid meningioma is an uncommon variant of meningioma and corresponds to grade II tumor in the World Health Organization Classification of Tumors of the Nervous System 2007 because of its more aggressive behavior and increased likelihood of recurrence. A 75-year-old female was referred to the neurosurgery department complaining of headache, syncope, and seizure.

Higher Ki67 expression is associates with unfavorable prognostic factors and shorter survival in breast cancer.

Background: The prognostic value of the Ki67 expression level is yet unclear in breast cancer. The aim of this study was to investigate the association between Ki67 expression levels and prognostic factors such as grade, Her2 and hormone receptor expression status in breast cancers.

Materials And Methods: Clinical and pathological features of the patients with breast cancer were retreived from the hospital records.

The effect of topical minoxidil pretreatment on nonsurgical delay of rat cutaneous flaps: further studies.

Unlabelled: The purpose of this study was to determine the effectiveness of topically applied minoxidil in the pharmacological delay phenomenon and to demonstrate the comparable microscopic and macroscopic changes between minoxidil-pretreated flaps and surgically delayed flaps. A modified version of the McFarlane flap was used. Group 1 rats, in which a caudally based dorsal skin flap was raised and sutured back, were the control group.

Tularemia: potential role of cytopathology in differential diagnosis of cervical lymphadenitis: multicenter experience in 53 cases and literature review.

Tularemia is a zoonosis caused by Francisella tularensis. Tularemia outbreaks occurred in Central Anatolia during 2009 and 2011. We evaluated the clinical characteristics and cytomorphologies of fine needle aspirations (FNAs) from cervical lymph nodes in serologically confirmed tularemia cases.

Antitumoral effects of Allium sivasicum on breast cancer in vitro and in vivo.

This work aims to investigate the antiproliferative properties of Allium sivasicum (AS) on breast cancer. AS extracts were studied for cytotoxicity against the breast cancer cell lines. In vitro apoptosis studies of breast cancer cells were performed by annexin V staining in flow cytometry analyses.

Immunohistochemistry with apoptotic-antiapoptotic proteins (p53, p21, bax, bcl-2), c-kit, telomerase, and metallothionein as a diagnostic aid in benign, borderline, and malignant serous and mucinous ovarian tumors.

Background: In many tumors including ovarian cancer, cell proliferation and apoptosis are important in pathogenesis and there are many alterations in most of the genes related to the cell cycle. This study was designed to evaluate immunohistochemistry with apoptotic-antiapoptotic proteins (p53, p21, bax, and bcl-2), c-kit, telomerase, and metallothionein as a diagnostic aid in typing of benign, borderline, and malignant serous and mucinous ovarian tumors.

Methods: Total of 68 ovarian tumors, 25 benign [13 (19.

Canalicular adenoma of the palate.

Canalicular adenomas are uncommon, benign epithelial neoplasm of the salivary glands that usually involve the upper lip and the buccal mucosa of elderly people. Differential diagnosis of the canalicular adenoma versus adenocarcinoma is important because it may result in unjustified radiotherapy or extensive and aggressive surgery. Despite the benign nature of canalicular adenomas, complete surgical removal and a regular clinical follow-up are recommended.

Investigation of wound healing in rat lung tissues in the postpartum period.

To assess the wound healing capabilities of damaged lung tissue in the postpartum period, we investigated the parameters related to wound healing in a rat model of lung damage. Rats were divided into six groups: IA, IB, II, IIIA, IIIB and IV (n=7 in each group). Group IA included rats not in the postpartum period that were sacrificed on the third day after lung injury, group IB included rats not in the postpartum period that were sacrificed on the tenth day after lung injury, group II included rats not in the postpartum period that did not receive lung injury, group IIIA included rats in the postpartum period that were sacrificed on the third day after lung injury, group IIIB included rats in the postpartum period that were sacrificed on the tenth day after lung injury and group IV included rats in the postpartum period without lung injury.

Effect of topically applied minoxidil on the survival of rat dorsal skin flap.

Background: Flap necrosis still is a challenging problem in reconstructive surgery that results in irreversible tissue loss. This study evaluated the effect of topically applied minoxidil on angiogenesis and survival of a caudally based dorsal rat skin flap.

Methods: For this study, 24 male Wistar rats were randomly divided into three groups of eight each.

Antitumoral effects of Melissa officinalis on breast cancer in vitro and in vivo.

Background: There is a long standing interest in the identification of medicinal plants and derived natural products for developing cancer therapeutics. Here we investigated the antiproliferative properties of Melissa officinalis (MO) from Turkey on breast cancer.

Methods: MO extracts were studied for cytotoxicity against breast cancer cell lines (MCF-7, MDA-MB-468 and MDA-MB-231).

Primary malignant melanoma of the nasal cavity.

Primary malignant melanoma of the nose and paranasal sinus mucosa is a rare disease and seen in less than 1% among all melanomas. Malignant melanomas have 2 origins: cutaneous and mucosal. The mucosal form has a worse prognosis because of its aggressiveness compared with that of the cutaneous form.

Pulmonary toxicity of chronic exposure to tobacco and biomass smoke in rats.

Objective: The objective of this study was to examine the separate and combined effects of tobacco and biomass smoke exposure on pulmonary histopathology in rats.

Introduction: In addition to smoking, indoor pollution in developing countries contributes to the development of respiratory diseases.

Methods: Twenty-eight adult rats were divided into four groups as follows: control group (Group I, no exposure to tobacco or biomass smoke), exposed to tobacco smoke (Group II), exposed to biomass smoke (Group III), and combined exposure to tobacco and biomass smoke (Group IV).
