How to perform an excellent radiology board examination: a web-based checklist.

Background: Board exams are now considered as means of quality procedures that aim to keep the professional knowledge and skills of the physicians at the highest level. In addition, for an assessment to be scientifically valid, it has to be done within defined standards. Although there are different sources in this field, there is a need for a resource that details the steps required for the examinations to be performed perfectly, brings descriptions of the reasons for the procedure and associates the steps with assessment standards.

The evaluation of early stage oxidative status in streptozotocin induced diabetes in rats.

Early-stage diabetes can be defined as the stages before absolute insulin deficiency in patients. In this study, the early stage oxidative effect of streptozotocin(STZ) induced diabetes mellitus was evaluated. 28 male adult Sprague-Dawley rats were divided into four groups; control group and 7th, 14th, 21st days diabetic groups.

Calcium Fructoborate Prevents Skin Cancer Development in Balb-c Mice.

Tumor microenvironment, genetic, and non-genetic factors are responsible for the atypical metabolic feature of cancer cells. Aberrant activity of PI3K/Akt pathway, increased glycolytic flux, and decreased intracellular pH gradient are the leading causes of this feature. Calcium Fructoborate (CaFB), a sugar-borate ester, has major benefits for human health.

PRECLINICAL STUDENTS' VIEWS ON MEDICAL ETHICS EDUCATION: A FOCUS GROUP STUDY IN TURKEY.

Aim: We aimed to receive the opinions of the preclinical medical students on medical ethics education, and to present some suggestions for the education program.

Methods: Focus group discussions were held with third-grade medical students. The analyses were implemented using Creswell's six-step qualitative data analysis.

Exposure of Students to Emotional and Physical Violence in the School Environment.

Introduction: While peer abuse or physical violence in school is emphasized more, the physical and emotional violence caused by school staff has been emphasized less. The purpose of this study was to investigate the variables related to emotional and physical violence that students are exposed to in the school environment.

Methods: This cross-sectional and descriptive study was conducted by applying a questionnaire to 434 fifth-grade students receiving education in the primary schools in Konak district of Izmir province.

A multicenter study: how do medical students perceive clinical learning climate?

Background: The relationship between students and instructors is of crucial importance for the development of a positive learning climate. Learning climate is a multifaceted concept, and its measurement is a complicated process. The aim of this cross-sectional study was to determine medical students' perceptions about the clinical learning climate and to investigate differences in their perceptions in terms of various variables.

Sexual attitudes, behaviour changes and opinions of interns in Izmir, Turkey.

Objectives: To evaluate sexual attitudes, behaviour and opinions of students at the end of their medical education studies in Izmir, Turkey, and compare findings with the results of the study carried out when they were first-year students.

Methods: A cross-sectional and longitudinal study, with data collected via a questionnaire.

Results: 'Friends' were most often mentioned as the source of their personal sexual information by students on both occasions.

An example of program evaluation project in undergraduate medical education.

Revisions to existing program evaluation approaches of the Dokuz Eylul University School of Medicine (DEUSM) were made by the Medical Education Department in June 2005. After considering several evaluation models, a mixed evaluation model was developed to meet institutional needs. The general program evaluation plan was structured as areas of inquiry under the three main program evaluation questions: what are the effects of the educational program on students and graduates, what are the effects of the educational program on trainers, and is the educational program being implemented as planned.

Sexual attitudes and risk-taking behaviors of high school students in Turkey.

Background: The risk of sexually transmitted diseases is high but opportunities of sexual education for adolescents are limited in Turkey. The aim of this study was to evaluate sexual attitudes and behaviors and to determine the predictors of sexual initiation among adolescents.

Methods: A questionnaire designed by the researchers was administered to 861 senior year high school students in their classrooms.

Effects of febrile and afebrile seizures on oxidant state in children.

No comparative studies have addressed the oxidant and antioxidant states of blood and cerebrospinal fluid. To reveal this differential state, the study was designed to identify the seizure type with the worse prognosis by determining erythrocyte arginase and erythrocyte catalase, plasma and cerebrospinal fluid malondialdehyde, and plasma and cerebrospinal fluid nitric oxide levels. Study groups were classified as febrile (group 1, n = 21), afebrile (group 2, n = 21), and control (group 3, n = 41, subdivided as 3a, febris positive, convulsion negative, and 3b, febris negative, convulsion negative).

Sexual behaviours and contraception among university students in Turkey.

The aim of this study was to evaluate the sexual attitudes and behaviours of university students. An anonymous questionnaire was administered to 550 final-year university students aged 20-25 years in Izmir, Turkey. Male students opposed premarital sexual intercourse for both genders more than female students did.

Perceptions of first and third year medical students on self-study and reporting processes of problem-based learning.

Background: The objective of this study is to investigate the perceptions of first and third year medical students on self-study and reporting processes of Problem-based Learning (PBL) sessions and their usage of learning resources.

Methods: The questionnaire applied to the students consisted of; questions about students' perceptions on searching and preparing phases of the self-study process, the breadth and depth of discussion during reporting phase and the usage of learning resources.

Results: First-year students spent more time for self-study and more highly rated the depth of discussion compared to third-year students.

Effects of dietary vitamin E and selenium on arginase activity in the liver, kidneys, and heart of rats treated with high doses of glucocorticoid.

The effects of dietary intake of vitamin E and selenium on arginase activity in the liver, kidneys, and heart of rats treated with high doses of prednisolone were investigated. Rats were divided into five groups. Groups 3, 4, and 5 received a daily supplement in their drinking water of vitamin E, Se, and a combination of vitamin E and Se, respectively, for 30 days.

Oxidative damage and antioxidant enzyme activities in experimental hypothyroidism.

Free radicals are now well known to damage cellular components. To investigate whether age and thyroid level affect peroxidation speed, we examined the levels of malondialdehyde and antioxidant enzyme activities in different age groups of hypothyroid rats. Hypothyroidism was induced in 30- and 60-day-old Wistar Albino rats by the i.

Comparison of pyruvate kinase variants from breast tumor and normal breast.

Background: Pyruvate kinase isozymes in human breast tumor tissue were compared in this study with normal human breast tissue. Two forms of pyruvate kinase present in normal and tumor human breast were purified by ammonium sulfate precipitation, dialysis, gel filtration, ion exchange, and affinity chromatography. Molecular weight of the native enzyme was determined.
