The effect of learning styles and study behavior on success of preclinical students in pharmacology.

Objectives: To evaluate the effect of learning styles and study behaviors on preclinical medical students' pharmacology exam scores in a non-Western setting.

Materials And Methods: Grasha-Reichmann Student Learning Study Scale and a modified Study Behavior Inventory were used to assess learning styles and study behaviors of preclinical medical students (n = 87). Logistic regression models were used to evaluate the independent effect of gender, age, learning style, and study behavior on pharmacology success.

Evaluation of lipid peroxidation and oxidative DNA damage in patients with periodontitis and hyperlipidemia.

Background: The purpose of this study is to determine the serum levels of malondialdehyde (MDA), as a lipid peroxidation marker, and 8-hydroxydeoxyguanosine (8-OHdG), as an oxidative DNA damage marker, in patients with chronic periodontitis (CP) and hyperlipidemia.

Methods: A total of 74 individuals were divided into four age- and sex-matched groups: 18 patients with hyperlipidemia and CP (HLp), 18 periodontally healthy patients with hyperlipidemia (HLh), 19 systemically healthy individuals with CP (Cp), and 19 systemically and periodontally healthy controls (Ch). Clinical periodontal parameters were measured, and serum lipids, MDA, and 8-OHdG levels were assessed in blood samples.

Acetylsalicylic acid and ascorbic acid combination improves cognition; via antioxidant effect or increased expression of NMDARs and nAChRs?

Chronic inflammation occurs systematically in the central nervous system during ageing, it has been shown that neuroinflammation plays an important role in the pathogenesis of many neurodegenerative disorders. Aspirin, a nonselective COX inhibitor, as well as ascorbic acid, has been purported to protect cerebral tissue. We investigated the effects of subchronic aspirin and ascorbic acid usage on spatial learning, oxidative stress and expressions of NR2A, NR2B, nAChRα7, α4 and β2.

Medical students' participation in and perception of unprofessional behaviors: comparison of preclinical and clinical phases.

We aimed to compare reported observations, participation in, and perceptions of unprofessional behaviors across preclinical and clinical medical students using a 23-item questionnaire that asked participants whether they witnessed or participated in the behavior and considered it unprofessional. Overall, 111 preclinical (year 3) and 104 clinical (year 4) students responded. For all of the behaviors, significant positive correlations were present between participation and affirmative perceptions.

Are there any remarkable effects of prenatal exposure to food colourings on neurobehaviour and learning process in rat offspring?

Objective: Artificial food colourings and additives (AFCAs) have long been discussed to have adverse effects on cognition and behaviour in children. In this study, our aim was to assess the probable side effects of prenatal exposure to colouring food additives on neurobehaviour and spatial learning process.

Methods: We administered 'no observable adverse effect levels' (NOAELs) of common used AFCAs as a mixture (erythrosine, Ponceau 4R, Allura Red AC, Sunset yellow FCF, tartrazine, Amaranth, Brilliant Blue, Azorubine and Indigotine) to female rats before and during gestation and tested their effects on spatial working memory and behaviour in their offspring.

Do learning approaches of medical students affect their satisfaction with problem-based learning?

The aim of this research was to determine the satisfaction of medical students with problem-based learning (PBL) and their approaches to learning to investigate the effect of learning approaches on their levels of satisfaction. The study group was composed of medical students from three different universities, which apply PBL at different levels in their curricula. The revised two-factor study process survey was applied to the study group to determine their approaches to learning as "deep" or "surface" learning.

Effects of maternally exposed coloring food additives on receptor expressions related to learning and memory in rats.

Exposure to artificial food colors and additives (AFCAs) has been implicated in the induction and severity of some childhood behavioral and learning disabilities. N-methyl-D-aspartate receptors (NMDARs) and nicotinic acetylcholine receptors (nACHRs) are thought to be effective in the learning and memory-generating process. In this study, we investigated the effects of intrauterine exposure to AFCAs on subunit concentrations of NMDARs and nAChRs isoforms in rats.

Examination of adhesion molecules, homocysteine and hs-CRP in patients with polygenic hypercholesterolemia and isolated hypertriglyceridemia.

Background: Increased levels of selectins, adhesion molecules, hs-CRP and homocysteine are considered important as indicators of atherosclerosis. There is a significant amount of evidence that high LDL-C levels are a risk factor for coronary artery disease, whereas the relevance of isolated triglycerides is controversial. The present study aims to compare the levels of homocysteine, hs-CRP, E-selectin, sP-selectin, VCAM-1, ICAM-1 in patients with isolated hypertriglyceridemia and polygenic hypercholesterolemia.

[Does the short-term mortality differ between men and women with first acute myocardial infarction?].

Objective: Women with myocardial infarction (MI) have been reported to have worse short-term prognosis than men. We aimed to compare men and women with first MI regarding 28 days survival, cardiovascular (CV) risk factors, clinical findings, and the treatment in the emergency setting.

Methods: One-hundred and seventy-five consecutive patients with first MI admitted to the emergency department of our hospital within one year were included in the study.
