Persistent proatlantal artery type 1 is one of the four anastomotic vessels between the carotid and vertebrobasilar arterial systems. Persistence of this embryonic anastomosis is extremely rare. We present such a case with bilateral persistent proatlantal arteries that arose from internal carotid arteries, entered the skull via the foramen magnum and united with the horizontal portions of vertebral arteries. We also mention its embryology, potential clinical implications, and differentiating features ...

Background: Generalized aggressive periodontitis is described as a clinical entity affecting both deciduous and permanent dentition with extensive alveolar bone loss, mobility, and exfoliation of all or many teeth. Controversy exists on dental implant use to restore missing dentition in younger patients. Methods: This case report presents a patient diagnosed with aggressive periodontitis who has lost all but 4 of her teeth. Her personal and functional desires led us to include implant therapy in ...

To report our results from a study of the endovascular treatment of flow restricting chronic atherosclerotic or catheter-induced segmental iliac artery dissections with bare stents.Thirty symptomatic patients with 32 lesions, including chronic atherosclerotic (n = 21) and catheter-induced (n = 11) segmental arterial dissections, were treated with primary stenting. The common iliac artery was involved in 19 lesions and the external iliac artery in the remaining 13. Two patients had two lesions in the same ...

Tramadol is a weak opioid agonist and an inhibitor of the reuptake of noradrenaline and serotonin. This study was undertaken to assess a possible pharmacological interaction of ondansetron, a serotonin-3 (5-hydroxytryptamine-3, 5-HT3) antagonist, and tramadol in an animal model for acute pain. Sixty-three male albino mice were randomly given saline, tramadol (10, 20, and 40 mg kg(-1)), ondansetron (1, 2, and 4 mg kg(-1)), or ondansetron (1, 2, and 4 mg kg(-1)) and tramadol (20 mg kg(-1), given 10 min ...

Vascular access device fragment embolization is a relatively rare but potentially serious complication. The purpose of this study was to report our experience with endovascular retrieval of embolized vascular access device fragments by interventional radiological means.Ten patients with a vascular access device fragment embolism were treated between 2004 and 2010. Attempted retrieval from the vascular bed was performed for five port catheter fragments, two temporary catheter fragments and three ...

Postoperative nausea and vomiting (PONV) are common and potentially distressing adverse events (AEs) associated with surgery and anesthesia. In patients undergoing laparoscopic cholecystectomy (LC) without antiemetic prophylaxis, the incidence of PONV can be as high as 72%.The aim of this study was to investigate the prophylactic antiemetic effects of ondansetron and granisetron in patients undergoing LC when these agents are administered before the end of surgery.Patients classified by the American ...

Most imaging techniques used for the evaluation of obstructive epiphora, such as DS DCG, rely on undesired ionizing radiation. We evaluated the efficacy of topical contrast-enhanced MR DCG in comparison with DS DCG in patients with obstructive epiphora who underwent balloon DCG or stent placement.Thirty-six LDSs of 21 patients treated with balloon DCG (n = 11) or stent placement (n = 11) were examined with MR DCG and DS DCG. Contralateral LDSs (n = 14) were also evaluated in patients with unilateral disease. ...

Introduction The knowledge of anatomic variations of the cerebral arterial circulation may be important to decide on the safest surgical or endovascular treatment method. Variations in the middle cerebral artery (MCA) territory seems to be less frequent than the other intracranial arteries. During the embryonic stage the primitive MCA is hypothesized to be made up of arterial twigs and these twigs will generate the definitive MCA at the end of the development stage. As in our cases, an early interruption ...

Coronary artery fistulae are very rare congenital anomalies which constitute 0.2–0.4% of all congenital heart diseases. The right chambers of the heart are the most frequent communication site of the coronary fistulae and may cause hemodynamic impairment in the coronary circulation. The fistulae arise frequently from right coronary and left anterior descending arteries. Fistulae from left circumflex artery are very rare. We report a case in which transcatheter embolization was performed with 3-mm ...

This article presents a review of the interventional radiological procedures in the lacrimal drainage system. Balloon dacryocystoplasty and nasolacrimal polyurethane stent placement are the main fluoroscopically guided interventions for the treatment of epiphora by recanalizing the obstructed LDS. These procedures can also be used for dacryolith removal and lacrimal sac abscess treatment.

The aim of this work was to determine the seasonal changes in the activities of selected biomarkers in Capoeta umbla (Heckel, 1843) caught from Uzuncayir Dam Lake (Tunceli, Turkey) and to evaluate the effects of environmental factors on these activities. Fish were sampled on seasonal basis, and superoxide dismutase, catalase, glutathione peroxidase activities and levels of glutathione and malondialdehyde in gills were determined. Significant variations of oxidative stress biomarkers were observed ...

An enzyme electrode for the specific determination of catechol was developed by using catechol oxidase (EC 1.10.3.1) from eggplant (Solanum melangena L.) in combination with a dissolved oxygen probe. Optimization studies of the prepared catechol oxidase enzyme electrode established a phosphate buffer 50 mM at pH 7.0 and 35°C to provide the optimum conditions for affirmative electrode response. The enzyme electrode response depended linearly on a catechol concentration range of 5•10(-7)-30•10(-5) M ...

A multi-lingual translation system must take fundamental differences between the characteristics of different alphabets such as Latin, Cyrillic, Chinese, Korean, and Arabic into account. The system presented in this paper can extract text from real-world images with appropriate heuristics for these alphabets, as well as de-skew, binarize, recognize, and translate ...
