Clinical course of pediatric large vascular anomalies located in the extremities.

Objective: Difficulties encountered in the diagnosis and treatment of vascular anomalies located in the extremities of the children. The most common vascular lesions are hemangiomas and venous malformations. The complex malformations, such as, Klippel-Trenaunay Syndrome are much less commonly encountered lesions.

Chitosan-co-Hyaluronic acid porous cryogels and their application in tissue engineering.

In this work, the usability of chitosan-co-hyaluronic acid cryogels as a tissue-engineering scaffold was investigated. Chitosan-co-hyaluronic acid cryogels were synthesized at subzero temperature. Cryogels which were composed of various compositions of chitosan and hyaluronic acid (0, 10, 20, 30 and 50wt% hyaluronic acid) was prepared.

Zwitterionic phosphorylcholine grafted chitosan nanofiber: Preparation, characterization and in-vitro cell adhesion behavior.

In this study, zwitterionic phosphorylcholine grafted electrospun chitosan fiber was accomplished in three steps: (1) Azide groups on the chitosan were regioselectively replaced with hydroxyl side group and then the product was electrospun. (2) Chitosan based macroinitiator was prepared using an azide-alkyne click reaction from azide-functionalized electrospun chitosan fiber. (3) Poly(2-methacryloyloxyethyl phosphorylcholine) (MPC) was grafted onto the electrospun chitosan fiber by atom transfer radical polymerization (ATRP) in order to enhance cellular viability and proliferation of 3T3, ECV and Saos.

Immobilization of α-amylase onto poly(glycidyl methacrylate) grafted electrospun fibers by ATRP.

In this study, novel α-amylase immobilized poly(vinyl alcohol) (PVA) nanofibers were prepared. The PVA nanofiber surfaces were functionalized with 2-bromoisobutyryl bromide (BiBBr) and followed by surface initiated atom transfer radical polymerization (SI-ATRP) of glycidyl methacrylate (GMA). The morphology of the poly(glycidyl methacrylate) (PGMA) grafted PVA nanofibers was characterized by scanning electron microscopy (SEM).

Bilateral multiple tumor-like endobronchial tuberculosis, diagnosed with bronchoscopic examination.

Endobronchial tuberculosis is defined as tuberculosis infection of tracheobronchial tree and it is not seen often in adult population. In the absence of parenchymal disease endobronchial tuberculosis is less well-recognized and can lead to difficulties in diagnosis. Our aim is to introduce a rare form of tuberculosis that is important because of high probability of developing severe bronchostenosis during its course.

Evaluation of a single-channel portable monitor for the diagnosis of obstructive sleep apnea.

Study Objective: To validate the ApneaLINK (AL) as an accurate tool for determining the presence of obstructive sleep apnea (OSA) in an at-risk sleep clinic population in a home test environment.

Methods: Consecutive participants referred with the suspicion of OSA were evaluated in the home with the AL portable monitor (AL Home), followed by simultaneous data collection with diagnostic polysomnography (PSG) and AL in the sleep laboratory (AL Lab). Prevalence, sensitivity, specificity, and ROC curves were calculated for PSG vs.

[Vocal cord functions in patients with asthma attack].

This study was planned to evaluate vocal cord functions and to establish underlying vocal cord dysfunctions (VCD) in patients with asthma attack. All patients admitted to emergency service of our hospital with asthma attack between February 01, 2007 and June 01, 2007 were included in the evaluation. After the evaluation, all patients regarded to have asthma attacks based on GINA 2006 guide were enrolled in the study.

Evaluation of the relationship between heart type fatty acid binding protein levels and the risk of cardiac damage in patients with obstructive sleep apnea syndrome.

The aim of this study was to establish cardiac damage related to nocturnal ischemia using heart type fatty acid binding protein (h-fabp), which reaches detectable levels in plasma after being released from myocytes in case of ischemia in obstructive sleep apnea syndrome (OSAS) patients without coronary artery disease (CAD). Fifty patients diagnosed with OSAS in our sleep laboratory with polysomnographic analysis (PSG), who did not have any previous history of cardiac disease and in whom CAD was ruled out with myocardium perfusion scintigraphy, were included in the study. Control group comprised 19 volunteers without history of cardiac disease and risk factors in whom OSAS was excluded with PSG analysis.
