Saliva/serum ghrelin, obestatin and homocysteine levels in patients with ischaemic heart disease.

Background: We aimed to compare ghrelin, obestatin, homocysteine (Hcy), vitamin B and folate levels in the serum and saliva of ischaemic heart disease patients.

Methods: Serum and saliva were collected from 33 ischaemic heart disease (IHD) patients and 28 age- and body mass index-matched healthy individuals. Levels of acylated and desacylated ghrelin, obestatin and Hcy were determined using the ELISA method.

Assessment of different folic acid supplementation doses for low-birth-weight infants.

Aim: The adequacy of 50 mcg folic acid supplementation given to low-birth-weight babies was investigated. The folate levels of the mothers and infants, and breastmilk, and the optimum dose for folic acid supplementation were also investigated.

Material And Methods: After obtaining blood from 141 low-birth-weight infants on the 1st day of life for serum and red cell folate levels, the infants were randomly allocated into three groups according to the folic acid supplement dose.

Maternal and neonatal outcomes in advanced maternal age: a retrospective cohort study.

Objectives: To describe the effect of extremely advanced maternal age (EAMA) on maternal/neonatal outcomes.

Methods: This was a case-control study in which 127 women ≥40 years at the time of delivery out of 2853 singleton hospital deliveries in Ondokuz Mayis University between 1 January 2008 and 31 August 2010 constituted the study group. One hundred and twenty-seven else were chosen randomly out of 2412, 21-35 years old women, via a computer system as controls.

Graphical modeling for item difficulty in medical faculty exams.

Background: There are different indexes used in the evaluation of exam results. One important index is the difficulty level of the item that is also used in this study to obtain control charts. This article offers some suggestions for the improvement of multiple-choice tests using item analysis statistics.

To Compare Time-Weighted Graphs to Evaluate the Inclination of the Acetabular Component of Patients Who Had Total Hip Replacement Surgery.

Time-weighted graphs are used to detect small shifts in statistical process control. The aim of this study is to evaluate the inclination of the acetabular component with CUmulative SUM (CUSUM) chart, Moving Average (MA) chart, and Exponentially Weighted Moving Average (EWMA) chart. The data were obtained directly from thirty patients who had undergone total hip replacement surgery at Ondokuz Mayis University, Faculty of Medicine.
