The Relationship between Primary Students’ Acquisition Levels of SPS and their Attitudes towards Science and Success

Araştırmanın amacı, ilköğretim yedinci sınıf öğrencilerinin fen ve teknoloji dersinde bilimsel süreç becerileri (BSB) kazanımlarını belirlemek, ayrıca öğrencilerin BSB ile akademik başarıları ve Fene yönelik tutumları arasında bir ilişki olup olmadığını saptamaktır. Bu amaç doğrultusunda araştırmacı tarafından, öğrencilere yönelik “Bilimsel Süreç Becerileri Testi” (BSBT) hazırlanmış ve uygulanmıştır. Öğrencilerin fen ve teknoloji dersine karşı ilgilerini ölçmek için, “Fen Bilgisi Dersine Yönelik Tutum Ölçeği” (FTDYTÖ) uygulanmıştır. Araştırmanın çalışma grubunu, 2007-2008 öğretim yılında Kocaeli ilinde öğrenim gören 828 ilköğretim yedinci sınıf öğrencisi oluşturmaktadır. Araştırma sonuçlarına göre; öğrencilerin BSB’nin orta düzeyde olduğu, BSB düzeyleri ile Fene yönelik tutumları ve akademik başarıları arasında pozitif ve anlamlı bir ilişki olduğu belirlenmiştir.The aim of this research is to determine the 7th grade students’ acquisition of science process skills (SPS) in science and technology courses. It is also aimed to determine whether there exists a relationship between their (SPS) and their attitudes towards science and academic success. For this purpose, a Science Process Skills Test (SPST) was developed and administered to students by the researcher. An Attitude towards Science Scale (ATSS) was administered to measure the interests of students towards science and technology courses. The sample consisted of 828 7th grade primary school students who were selected from 21 schools randomly in the province of Kocaeli. It was found that students’ have a medium level of SPS, and a positive and significant relationship between students’ level of SPS and their attitudes towards science and academic success

«Un raro caso di linfoma della trachea con stenosi severa»

Primary malignant lymphoma of the trachea is rare and its underlying mechanism remains unknown. Primary tracheal tumors are also very rare causes of airway obstructions. This case report features a 60 year-old woman who presented with the complaint of dyspnea. A mass narrowing the tracheal lumen posteriorly in the subglottic area and mediastinal lymphadenopathy was detected by computed tomography scan and a rijit bronchoscopy was performed. This showed polypoid, variable-sized, irregular nodules causing narrowing of the tracheal lumen over a 3 cm segment in the middle part of the trachea and a mass protruding into the tracheal lumen from the posterior part of the proximal trachea. Multiple biopsy was carried out from the nodules and the airway obstruction was treated with Argon Plasma Coagulation (APC). After removal of the debris, tracheal lumen patency was obtained. The histopathology examination revealed a small lymphocytic primary non-Hodgkin’s lymphoma of the trachea. To our knowledge, this is the first case of small lymphocytic primary tracheal lymphoma in the literature. © Mattioli 1885

Evaluation of multidrug resistance-1 gene C>T polymorphism frequency in patients with asthma

OBJECTIVES:Asthma is a chronic inflammatory lung disease characterized by bronchial hyperresponsiveness and airflow obstruction. Genetic and oxidative stress factors, in addition to pulmonary and systemic inflammatory processes, play a pivotal role in the pathogenesis of asthma. The products of the multidrug resistance-1 gene protect lung tissue from oxidative stress. Here, we aimed to evaluate the association between the multidrug resistance-1 gene C>T polymorphism and asthma with regard to oxidative stress-related parameters of asthmatic patients.METHODS:Forty-five patients with asthma and 27 healthy age-matched controls were included in this study. Blood samples were collected in tubes with ethylenediaminetetraacetic acid. DNA was extracted from the blood samples. The multidrug resistance-1 gene polymorphism was detected by polymerase chain reaction and a subsequent enzyme digestion technique. The serum levels of total oxidant status and total antioxidant status were determined by the colorimetric measurement method.RESULTS:The heterozygous polymorphic genotype was the most frequent in both groups. A significant difference in the multidrug resistance-1 genotype frequencies between groups indicated an association of asthma with the TT genotype. A significant difference between groups was found for wild type homozygous participants and carriers of polymorphic allele participants. The frequency of the T allele was significantly higher in asthmatic patients. The increase in the oxidative stress index parameter was significant in the asthma group compared with the control group.CONCLUSIONS:The multidrug resistance-1 gene C/T polymorphism may be an underlying genetic risk factor for the development of asthma via oxidant-antioxidant imbalance, leading to increased oxidative stress
