AIMS To evaluate the interleukin-1 beta (IL-1 beta) levels in gingival crevicular fluid (GCF) and serum in either naturally occurring (N-O) or experimentally induced (E-I) plaque-associated gingivitis. MATERIAL AND METHODS Thirty-seven periodontally healthy subjects were evaluated in real life conditions (N-O gingivitis) as well as after 21 days of(More)
The teat is the main entrance for pathogens into the mammary gland. It also acts as a sensory, motor and primary defence organ. This latter function is important in preventing intramammary infections while efficiency in preventing new infections is determined by teat tissue integrity. Machine milking may evoke mechanical and circulatory impairment in teat(More)
The objective of the study was to characterize a low-cost and reliable working standard material for quality control of estrogen receptor (ER) determination with dextran-coated charcoal (DCC) and enzyme immunoassay (EIA) methods. Human fibromatous uterine lyophilized cytosol demonstrated good characteristics of stability and applicability for this purpose.(More)
BACKGROUND There is now much data that suggest a relationship between angiogenesis and breast cancer prognosis. Angiogenesis is a multistep process resulting from an ordered set of events and regulated by positive and negative modulators of microvessels growth and by the expression of various proteolytic enzymes. MATERIALS AND METHODS We prospectively(More)
OBJECTIVE To test the effect of ampicillin on amniotic interleukin-6 (IL-6) and prostaglandin E2 (PGE2) release. METHODS In an in vitro study, IL-6 and PGE2 release from amnion-like Wistar Institute Susan Hayflick cells was assayed under basal conditions, as well as after incubation with ampicillin. In an in vivo study, amniotic fluid IL-6 was assayed in(More)
BACKGROUND The aim of the present study is to investigate the levels of some of the cytokines which may be involved in the mechanisms leading to the impairment of placental perfusion and to the onset of uterine contractions in pregnancies with fetal genetic abnormalities compared with controls. METHODS The amniotic fluid and maternal plasma levels of(More)
OBJECTIVE To compare euploid and aneuploid pregnancies with respect to maternal serum and amniotic fluid (AF) levels of the components of the plasminogen system. METHODS The study population consisted of 123 single pregnancies at the 17th gestational week, 16 with minor chromosomal abnormalities, 15 aneuploid, and 92 euploid. RESULTS Both groups with(More)
Amniotic fluid endothelin-1 (ET-1) levels were measured in 38 euploid and in 15 aneuploid pregnancies in the 17th gestational week. Varying distribution of the peptide levels was found in the two groups, with higher values in the pathological cases. Should this finding be confirmed in maternal blood, ET-1 could represent a further analyte to be used in(More)
The serological tumor marker tissue polypeptide antigen (TPA) and the more recently identified tissue-specific polypeptide antigen (TPS) have been reported to be indicators of the proliferation rate of the tumor. In the present investigation we compared the cytosol level of the two markers with the proliferative activity of the tumor measured using the(More)
An excellent correlation between ligand binding assay (LBA) and enzyme immunoassay (EIA) for both oestrogen (ER) and progesterone (PR) receptors has been reported. Nevertheless, considering that the clinical value of any discrepancy between LBA and EIA probably varies with the receptor level, we undertook a collaborative study in which a single saturating(More)
