background: human peripheral blood nk cells constitutively express cd56 and cd16 antigens. peripheral blood nk cells seem to be strongly related with decidual nk cells, and may reflect the decidual nk cell functional status. there are varied reports concerning the relationship between nk cell cytotoxicity in women with recurrent spontaneous abortion. objective: to study nk activity in women wit...

objective: stevioside is a natural non-caloric sweetener which has been reported to have anti-inflammatory activity.  the aim of  the present study was to examine in vitro and in vivo effects of  stevioside on rats  plasma levels of tumor necrosis factor- α (tnf-α),  interleukin-1β (il-1β), tnf-α and il-1β release from lipopolysaccharide(lps)-stimulated rat peripheral blood mononuclear cells (p...

conclusion in cases with critical atherosclerotic disease of anterior tibial artery, pta-based biphasic or triphasic retrograde collateral flow prevents ischemia, whereas monophasic support or no retrograde flow remains incapable. results in the patient group, 31 lower limb arteries, of total of 17 cases, were included. after compression maneuver, dpa in 11 cases (six right, five left) showed r...

from 1996 to 2002, fifty three patients with major beta-thalassemia received allogeneic peripheral blood stem cell trans plantation (pbsct). median age was 6 years .twenty two were class i, 17 class ii and 14 class iii. all of the donors were hla-identical. conditioning regimen for class i and ii patients consisted of cyclophosphamide (cy) 50 mg/kg/day for 4 days + busulfan (bu) 3.5 mg/kg for 4...

excessive scarring; paralleling the process in tendon reconstruction of the hand. inspired by the advantages of the two-stage technique in tendon grafting and with encouraging preliminary results, we aimed to investigate the two-stage nerve grafting technique as an alternative method of secondary nerve repair. methods:  thirty female rats (~200 g) were randomly distributed into two groups (n=15...

introduction: currently, neuroresearchers report that the median nerve shows severity-correlated intracarpal enlargement in idiopathic carpal tunnel syndrome (cts) as a most common peripheral neuropathic disorder. the purpose of this paper was to investigate ultrasonography morphological findings in patients with idiopathic cts and comparing some physical properties such as age, gender, bmi wit...

background: atherosclerosis of the peripheral arteries occurs in 12% of individuals at 65 years of age or older. at least 28% of these patients suffer from coronary heart diseases and 10% of them are afflicted with cerebrovascular diseases. to calculate the agreement between two diagnostic tests for peripheral arterial disease (pad), namely ankle brachial index (abi) and ultrasound duplex scann...

results stereoscopic displays of the nerves were obtained in all 24 elbows by vr, mip, and fiber tractography post-processing methods. the vr/mip post-processing methods were easier to perform compared to fiber tractography. there was no significant difference among the scores of fiber tracking and vr/mip reconstruction for single direction. the imaging quality scores of fiber tractography and ...
