OBJECTIVE The aim of this work was to explore the extent to which social, cognitive, emotional and physical aspects influence participation after a traumatic brain injury (TBI). DESIGN/SUBJECTS An explorative study of the patient perspective of participation 4 years after TBI. The cohort consisted of all patients (age range 18-65 years), presenting in 1999-2000, admitted to the hospital (n = ...

Transient evoked otoacoustic emissions (TEOAEs) were recorded in 30 normal-hearing subjects to nonlinear clicks while continuous contralateral broadband noise (CBBN) was presented at 40, 50, 60, and 70 dB HL. Thirty subjects between 20 and 79 years were divided system-atically into six-decade age groups, five subjects per group. All subjects in each group had hearing thresholds of 20 dB HL or b...

The aim of the present study was to investigate the impact of an oral glucose load on circulating insulin and glucose levels and arterial function in healthy non-diabetic subjects. Thirty-nine non-obese, healthy subjects (24 female, 15 male), aged 21.0+/-1.8 years of age, were randomly assigned to undergo either an OGTT (oral glucose tolerance test; 75 g of glucose) or administration of a place...

The aim of this study was to investigate the thyroid hormones (T3, T4) and its regulatory hormone (TSH) levels in obese women with sedentary life style. The studied population consists of 180 female subjects of age group 20-45 years. The subjects were divided into three categories on the basis of body mass index: normal weight subjects (n= 60) overweight subjects (n=60) and obese subjects (n=60...

Background: Synthetic biology is an interdisciplinary branch of biology and engineering. As synthetic biology develops into a promising science and engineering field, we need to clarify the purpose and nature of this science in terms of security, ethics and the recognition of the benefits of potential risks. The aim of this study was to evaluate the researchers’ attitudes toward synthetic biolo...

Background Levels of serum gonadotropins have direct effects on testicular functions and spermatogenesis. Assessment of levels of serum gonadotropins from fathered subjects and infertile patients indicates wide range diversity. In this study, we tried to find out whether the levels of seminal FSH and LH affect the parameters of seminal fluid analysis (SFA) and if there is any correlation betwee...

BACKGROUND Epidemiological studies have raised awareness of the problem of undiagnosed kidney disease and suggest that early identification and treatment will reduce the global burden of patients requiring dialysis. However, there are insufficient data on how to identify subjects who are at risk for developing overt kidney disease in a human immunodeficiency virus (HIV) population. METHODS A ...

BACKGROUND Our purpose in this study was to clarify whether differences in subject group attributes could affect data acquisition in proton magnetic resonance spectroscopy ((1)H-MRS). METHODS Subjects without diabetes mellitus (DM) were divided into two groups (group A, in their 20s; group B, 30-60 years old). Subjects with DM formed group C (30-60 years old). The numbers of subjects were 19,...
