METHODS Twenty-one, male New Zealand white rabbits were randomly divided into 3 groups of 7 rabbits each: group 1 (control), group 2 (SAH only), group 3 (SAH + NAC treatment). NAC (150 mg/kg, single dose, IP) was administered just before SAH and(More)

The major focus is on haptic feedback devices allowing the operator to touch virtual and remote objects. The paper presents selected hardware developments and application studies in the haptic research area carried out at the(More)
Common variable immunodeficiency (CVID) is a heterogenous group of predominantly antibody-deficiency disorders that make up the greatest proportion of patients with symptomatic primary hypogammaglobulinemia. The rare coincidence of amyloidosis and hypogammaglobulinemia has been reported previously. Contrary to the usual insidious, slowly progressive disease(More)
Thioredoxin (Trx) is a redox active protein that regulates several physiological and biochemical functions, such as growth, apoptosis and cellular defense. The function of Trx itself is regulated by thioredoxin reductase (TrxR). Studies performed in a variety of human primary tumors have shown that thioredoxin reductase 1 (TrxR1) is overexpressed in tumoral(More)
Common variable immunodeficiency is the most common symptomatic primary immune deficiency characterized by hypogammaglobulinemia, recurrent infections, and increased risk of autoimmune disease and malignancy. Secondary amyloidosis develops from chronic inflammatory conditions. The co-existence of CVID (especially in patients with bronchiectasis) and(More)
Clinical examination is very important in the practice of medicine. In patients presenting with a supraclavicular mass, a number of diseases including cancer should be ruled out. Two patients who presented with a bulky left supraclavicular mass were evaluated. Their medical history revealed complaints attributed to lower urinary tract infection. We(More)
