(2001)[Abstract Not Available] -
A left pulmonary artery aneurysm secondary to pulmonary hypertension
(2001)We report a case of pulmonary trunk aneurysm extending into the left pulmonary artery due to pulmonary hypertension secondary to mitral valve disease. The mitral valve was replaced with a bileaflet mechanical prosthesis. ... -
Hip fracture-dislocation (Pipkin type IV) associated with an apparent traumatic aortic valve rupture. Case history
(2001)Traumatic aortic valve rupture with resultant aortic insufficiency is a rare complication of blunt trauma. Here reported is a case with a posterior fracture-dislocation of the hip (Pipkin type-IV) and an undisplaced sternum ... -
Coronary bypass surgery in octogenarians
(2001)OBJECTIVE: The age of the patients referred for coronary bypass surgery is getting older progressively. Early and late postoperative outcome of octogenarians were evaluated and compared with younger age group in this study. ... -
The involvement of nitric oxide in the analgesic effects of ketamine
(Pergamon-Elsevier Science Ltd, 2002)We investigated the contribution of NO-cyclic GMP (cGMP) pathway to the antinociceptive effects of ketamine in mice by using the nitric oxide synthase inhibitor nitro(g)-L-arginine methyl ester (L-NAME). Intraperitoneal ... -
Investigation of transfusion transmitted viruses in cases clinically suspected of posttransfusion hepatitis with undetermined ethiology
(Pergamon-Elsevier Science Ltd, 2002)Transfusion transmitted viruses (TTV) were investigated in cardiac surgery cases who were previously transfused with blood and/or blood products and were suspected of having posttransfusion hepatitis (PTH) based on the ... -
Does normoxemic cardiopulmonary bypass prevent myocardial reoxygenation injury in cyanotic children?
(W.B. Saunders Co Ltd, 2002)Objective: To evaluate whether the deleterious effect of cardiopulmonary bypass (CPB) can be prevented by controlling PaO2 in cyanotic children. Design: Prospective randomized clinical study. Setting: Single university ... -
Pedicular stress fracture in lumbar spine
(Elsevier Science Inc, 2002)The purpose of this article is to report two cases of pedicular stress fracture of the lumbar spine which is an uncommon cause of low back and leg pain. The relevant literature is reviewed and features of the cases that ... -
Cosmic ray intensity variation during a CME
(Pergamon-Elsevier Science Ltd, 2002)The June 6 2000 coronal mass ejection was an exceptional full halo which made it possible to measure cosmic ray (CR) decrease with a simple experimental set-up. Variation in the local secondary cosmic ray density has been ... -
Muscle metastasis as initial manifestation of epidermoid carcinoma of the lung
(Elsevier Science London, 2002)Typical sites of squamous cell carcinoma of lung metastases include liver brain bones pulmonary and adrenal glands. In advanced dissemination it can rarely involve the skeletal muscle. The patient in this case report was ... -
Comparison of the BBL-mycobacteria growth indicator tube method with culture in the diagnosis of tuberculosis and evaluation of the resistance patterns of isolated strains to four major drugs
(Karger, 2002)The BBL-mycobacteria growth indicator tube system (MGIT) is used for a rapid detection of the presence of mycobacteria. Our study aimed to compare MGIT with the Lowenstein-Jensen (LJ) reference method in clinical samples ... -
Spontaneous ureteral rupture: Is immediate surgical intervention always necessary? Presentation of four cases and review of the literature
(Mary Ann Liebert Inc Publ, 2002)Purpose: We report our experience with spontaneous ureteral rupture (SUR) managed conservatively. Case Reports: Data on three men and one woman 53 to 89 years old (mean age 73) with SUR were retrospectively evaluated. The ... -
Chelate extraction of transition metal ions by ethylene diamine diacetic acid with n-substituted octadecyl groups
(Taylor & Francis Inc, 2002)An organic-soluble chelating agent NN'-di-n-octadecyl ethylenediamine-NN'-diacetic acid (DOED) has been synthesized in two steps by (i) condensation of dibromoethane with 1-amino octadecane (octadecylamine) and (ii) ... -
Metalization of polymer beads via polymer-supported hydrazines as reducing agents
(John Wiley & Sons Inc, 2002)A new method for depositing metal onto a polymer surface has been developed in which the metal coating of polymer beads is performed with hydrazine functions as reducing agents on the surface of the polymer itself. In this ... -
Prospective evaluation of platelets prepared by single and random methods during 5 days of storage: aspects related to quality and quantity
(Pergamon-Elsevier Science Ltd, 2002)Platelets which have an important role in hemostatic mechanisms and which were prepared by single and random methods were investigated to measure quantity and aggregation response during 5 days of storage. The aggregation ... -
