Erythrocyte-associated apolipoprotein B and its relationship with clinical and subclinical atherosclerosis.

Background: Apolipoprotein (apo) B-containing lipoproteins are closely linked to atherogenesis. These lipoproteins are transported in plasma and are also associated with blood leucocytes. Our aim was to investigate whether apoB-containing lipoproteins are also present on the surface of erythrocytes and investigate the relationship with the presence of atherosclerosis in a cross-sectional study.

Success rate of nonsurgical endodontic treatment of nonvital teeth with variable periradicular lesions.

Introduction: Bacterial infection of tooth pulp can progress into periapical diseases. Root canal treatment has been established as the best treatment. In cases of failure, nonsurgical retreatment of teeth is preferred to surgical procedure and extraction.

Mannose binding lectin 2 haplotypes do not affect the progression of coronary atherosclerosis in men with proven coronary artery disease treated with pravastatin.

Objective: Mannose binding lectin (MBL) is one of the three initiators of complement activation. Polymorphisms of the MBL2 gene and its promoter, and especially haplotypes, determine MBL plasma levels. MBL deficiency has been associated with the development of atherosclerosis.

Retrospective dosimetry using synthesized nano-structure hydroxyapatite.

Micro and nano-structure hydroxyapatite samples were synthesized via several different methods. The samples were characterised utilising the Fourier transmission infra-red, scanning electron microscope and X-ray diffraction methods, to find out the structure most similar to human tooth enamel, and the best method was found. The electron paramagnetic resonance (EPR) signals of the gamma-irradiated samples were measured using an EPR spectrometer system.

Cell-mediated lipoprotein transport: a novel anti-atherogenic concept.

Lipoprotein transport is thought to occur in the plasma compartment of the blood, where lipoproteins are modulated by various enzymatic reactions. Subsequently, lipoproteins can migrate through the endothelial barrier to the subendothelial space or are taken up by the liver. The interaction between pro-atherogenic (apoB-containing) lipoproteins and blood cells (especially monocytes and macrophages) in the subendothelial space is well known.

Reliability of fixation preference for detecting amblyopia in strabismic patients.

Purpose: To evaluate the association between fixation preference (FP) and amblyopia in strabismic patients.

Methods: This study includes 50 patients with horizontal, vertical or mixed strabismus of at least 10 prism diopters. Best-corrected monocular visual acuity (VA) was measured using Snellen E-chart and the presence of amblyopia was determined accordingly; FP was evaluated and graded from 0 to 3.

Mannose binding lectin deficiency and triglyceride-rich lipoprotein metabolism in normolipidemic subjects.

Mannose binding lectin (MBL) is one of the three initiators of complement activation and is therefore closely linked to inflammation. MBL deficiency has been associated with the generation of atherosclerosis. Since atherosclerosis, the complement system and postprandial lipemia are linked to inflammation, we studied postprandial lipoprotein metabolism in MBL deficiency.

Four-year incidence of sick leave because of neck and shoulder pain and its association with work and lifestyle.

Study Design: Four-year prospective cohort study.

Objective: To find the incidence of sick leave because of neck and shoulder pain (NSP) in industrial workers, and its association with work and lifestyle risk factors.

Summary Of Background Data: Longitudinal studies to investigate NSP incidence and risk factors are rare, and even fewer have been conducted in middle- and low-income countries.

Comparison of different methods to investigate postprandial lipaemia.

Postprandial hyperlipidaemia has been associated with coronary artery disease (CAD). We investigated which of the generally used methods to test postprandial lipaemia differentiated best between patients with premature CAD (50+/-4 years, n=20) and healthy controls. Furthermore, the effects of rosuvastatin 40 mg/day on postprandial parameters were assessed.

The Prevalence of Pediculosis capitis in Primary School Students in Bahar, Hamadan Province, Iran.

Background: Head lice infestation caused by Pediculus humanus var capitis (Pediculus capitis) is a worldwide public health concern that affects mostly school aged children. This descriptive, analytical study was carried out in 2008 to determine the prevalence of pediculosis capitis and some risk factors among primary-school pupils in Bahar, Hamadan Province, Iran.

Methods: We selected 900 pupils (50% girls and 50% boys) from 18 primary schools by multistage, systematic random sampling.

Is psychotherapy a reliable alternative to pharmacotherapy to promote the mental health of infertile women? A randomized clinical trial.

Objective: Women with fertility problems experience a higher prevalence of negative emotions than women without fertility problems. The goal of this study was to compare the effects of psychological intervention with psychotropic medication on the mental health improvement of depressed infertile women.

Study Design: In a randomized controlled clinical trial, 89 depressed infertile women that they were recruited and divided into three groups in three groups: cognitive behavior therapy (CBT), antidepressant therapy, and a control group.

Novel aspects of postprandial lipemia in relation to atherosclerosis.

Postprandial hyperlipidemia is considered to be a substantial risk factor for atherosclerosis. Interestingly, this concept has never been supported by randomized clinical trials. The difficulty lies in the fact that most interventions aimed to reduce postprandial lipemia, will also affect LDL-C levels.

Occupational neck and shoulder pain among automobile manufacturing workers in Iran.

Background: Work-related musculoskeletal disorders (MSDs) of the upper extremities are a major problem globally, though most relevant studies have been reported from high income countries.

Aims And Methods: The prevalence of neck and shoulder pain and its association with work-related physical and psychosocial factors and life style was determined by a cross-sectional survey using the Nordic Musculoskeletal Questionnaire (NMQ) in the largest Iranian car manufacturing company, with more than 18,000 employees.

Results: A total of 14,384 (79.

Effect of psychosocial factors on low back pain in industrial workers.

Aim: To test the hypothesis that workplace psychosocial factors such as demand, control, support, job satisfaction and job appreciation can predict the future onset of disabling low back pain (LBP).

Methods: The present study involved a prospective cohort of 4500 Iranian industrial workers. Data were gathered by means of a self-reported questionnaire about LBP, as well as working life exposure, lifestyle factors, social exposures, co-morbidity, life events and psychosomatic complaints in 2004.

Leukocyte activation by triglyceride-rich lipoproteins.

Objective: Postprandial lipemia has been linked to atherosclerosis and inflammation. Because leukocyte activation is obligatory for atherogenesis, leukocyte activation by triglyceride-rich lipoproteins (TRLs) was investigated.

Methods And Results: The expression of CD11b and CD66b after incubation with glucose and native and artificial TRLs (NTRL and ATRL) in vivo and in vitro was evaluated by flowcytometry.

Reliability and validity study of Persian modified version of MUSIC (musculoskeletal intervention center) - Norrtalje questionnaire.

Background: Musculoskeletal disorders (MSDs) are a major health problem in the world. Self-reported questionnaires are a known method for estimating the prevalence of MSDs among the population. One of the studies concerning MSDs and their relation to work-related physical and psychosocial factors, as well as non-work-related factors, is the MUSIC-Norrtalje study in Sweden.

Postprandial inflammation and endothelial dysfuction.

Postprandial hyperlipidaemia is a common metabolic disturbance in atherosclerosis. During the postprandial phase, chylomicrons and their remnants can penetrate the intact endothelium and cause foam cell formation. These particles are highly atherogenic after modification.
