Some human sera contain factors which induce in gonococci a resistance to killing by fresh human sera. Individuals with serum containing these factors might possibly be more prone to gonorrhoea. A survey of the sera of 50 female and 50 male patients with gonorrhoea for resistance-inducing capacity showed, however, that the proportions of positive sera (24% for women, 28% for men) were not signi...

An immunochromatographic test for the simultaneous detection of Babesia caballi- and B. equi-specific antibodies (BceICT) was developed using a recombinant B. caballi 48-kDa rhoptry protein (rBc48) and a recombinant truncated B. equi merozoite antigen 2 (rEMA-2t). An evaluation of the ability of the BceICT to detect antibodies in sera from uninfected horses and experimentally infected horses sh...

Reverse sequence screening for syphilis (RSSS) (screening with treponemal tests, followed by confirmation with nontreponemal tests) has been increasingly adopted. CDC recommends confirmation of discordant results (reactive EIA/CIA and nonreactive nontreponemal test) with Treponema pallidum particle agglutination assay (TP-PA). We characterized sera with discordant results from RSSS with Archite...

Objectives: To investigate the role of reactive oxygen species (ROS) in the development of the various patterns of systemic sclerosis (SSc) and the mechanisms of ROS production by endothelial cells and fibroblasts. Methods: Production of hydrogen peroxide (H2O2), nitric oxide (NO) and cellular proliferation were determined following incubation of endothelial cells and fibroblasts with 56 SSc an...

A monoclonal competitive radioimmunoassay (CompRIAm) which detects antibody to herpesvirus simiae (B virus) in monkey and human sera and antibody to SA8 virus in monkey sera but not antibody to herpes simplex virus in human sera is described. Of 232 serum samples from wild-caught cynomolgus monkeys, 117 serum samples were positive when tested by CompRIAm. The results were in close agreement (97...

INTRODUCTION AND OBJECTIVE Due to the nature of their work, foresters are exposed to many infectious pathogens from the wildlife reservoir. The primary aim of this study was to assess their contact with these pathogens. MATERIAL AND METHODS Sera and antibodies, mainly of IgG class against selected infectious factors, collected from a group of 216 employees of National Forests from eastern and...

OBJECTIVE To compare sera levels of CEA and CA19-9 and tissular expression of the CA19-9 and to correlate these with morphological features of the colorectal carcinoma. METHODS Forty five patients with colorectal carcinoma underwent surgical treatment following measurement of pre-operative levels of CA19-9 and CEA. Sera levels of CEA = 5.0ng/ml and CA19-9 = 37UI were deemed high values. Evalu...

Factors that influence the proliferation of marrow elements can be detected in sera. To determine the function and to compare the effect of these factors, cells were obtained from patients with normal and leukemic bone marrows. The effects of drug-induced stimulatory and inhibitory sera and leukemic pretreatment sera over time (0 to 6 days) on proliferation and granulocytic morphology of normal...

Sera (920) were tested to evaluate the use of heated versus unheated sera in the hemagglutination treponemal test for syphilis. The heated and unheated samples were tested on the same day with the hemagglutination treponemal test for syphilis kit according to the manufacturer's protocol. Agreement of results between the heated and unheated sera was 99.2%. The reading pattern of agglutination wa...

Son dönemlerde sera gazı emisyonundaki önemli artış göstermiş ve bundan dolayı çevre kirliliği sorunu küresel bir sorun haline gelmiştir. Sera emisyonunda en büyük payı ise karbondioksit emisyonu almaktadır. Bu çalışmanın amacı ABD’nin 2000M1-2021M11 döneminde sektörlere göre CO2 emisyon ile iklim politikası belirsizliği endeksi, enerji tüketimi ekonomik büyüme arasındaki ilişkiyi incelemektir....
