The aim of this study is to evaluate analytical methods such as ELISA and OPKA that measure the activity of vaccine-induced pneumococcal antibodies. After validation of ELISA and OPKA, pneumococcal antibodies were measured by ELISA and OPKA in paired samples before and after immunization (pneumococcal PS vaccine) in children, adults and elderly.
detection of anti-ds DNA in patients with rheumatic diseases by two methodes : immunofluorescence & ELISA
in this resarch we will use ELISA Technique to estimate Human Transcriptional Activator(MYB) Expression .compare it by Immmunohistochemistry analysis of MYB Expression in the malignant and benign salivary gland tumor
CDC recommends universal HIV testing in all adults, at least once during life, to reduce the pool of infected patients unaware of their status. Routine universal HIV testing can use "classical" ELISA tests from serum, or rapid tests, ideally from finger-stick whole blood (FSB), which have shown close predictive values from classical tests. The investigators will compare the acceptability and feasibility of the two methods.
To determine the ability of the Cimmunology process to lead to in vitro antibody production, the ability of the ELISA assays to detect any of those antibodies, and to establish the relationship between the ELISA results and the clinical / pathological status of the patient. The statistical significance of the CAAb test results will be determined.
The ALPCO Calprotectin ELISA is an in vitro diagnostic test intended to quantitatively measure concentrations of fecal calprotectin in human stool samples. Calprotectin is a protein biomarker of mucosal inflammation. Measurement of calprotectin can aid in the diagnosis of Inflammatory Bowel Diseases (IBD), specifically Crohn's Disease (CD) and Ulcerative Colitis (UC), as well as aid in the differentiation of IBD from Irritable Bowel Syndrome (IBS) when used in conjunction with ...
To improve upon the non-invasive detection of BCa by further validating a multiplex ELISA assay directed at a BCa-associated diagnostic signature in voided urine samples of patients with microscopic hematuria.
To improve upon the non-invasive detection of BCa by further validating a multiplex ELISA assay directed at a BCa-associated diagnostic signature in voided urine samples of patients with gross hematuria.
In children, it remains quite difficult even in developed countries, to prove a diagnosis of Tuberculosis (TB). New means for diagnosis of this disease are currently being researched. One candidate test is Lipoarabinomannan ELISA from Urine, which has shown good sensitivity of up to 80% in adults. Our study aims to evaluate this test in the diagnosis of children with TB.
The investigators aim to assess the overall accuracy of D-dimer values and FXIII activation peptide (FXIII-AP), using a newly developed ELISA test, to exclude CVT in patients with clinical suspicion of CVT.
Pityriasis alba (PA) is a common, benign skin disorder occurring predominantly in children and adolescents. It is characterized by ill-defined hypopigmented macules and patches, round or oval in shape. They are most commonly located on the face (especially the cheeks), arms, and upper trunk; and they are more noticeable in people with darker skin types. Sun exposure accentuates the lesions. Patients and their parents are often anxious about the cosmetic appearance of the lesion...
Voided urinary cytology (VUC) is the most widely used urine-based assay for detecting bladder cancer (BCa); however, it fails to detect approximately 50% of low-grade or early stage BCa when it is most curable. Furthermore, the detection rate of VUC for recurrent BCa is not much better. Because of this severe limitation, all patients who are under surveillance to monitor for recurrent BCa must undergo an invasive examination of the urinary bladder, where a miniature camera is i...
The purpose of this study is to assess: - TBE antibody persistence 24, 34, 46 and 58 months (as applicable) after the first booster TBE vaccination with FSME-IMMUN 0.5ml given in Study 223, by means of ELISA (IMMUNOZYM FSME IgG) and Neutralization test (NT), - TBE antibody response to a second booster vaccination with FSME-IMMUN 0.5ml in the present study, by means of ELISA and NT, - Safety of FSME-IMMUN 0.5ml after the second booster vaccinatio...
- To demonstrate the tests' performance when compared to the detection of PJI using the Musculoskeletal Infection Society (MSIS) criteria-based definition of PJI for diagnosing PJI.1 This criteria-based definition of PJI places emphasis on culture techniques that identify pathogens, but also provides for minor criteria that can be used to diagnose PJI; - To calculate the tests' clinical sensitivity, clinical specificity, positive predictive v...
The study is designed to measure serum and salivary CYFRA21-1 levels using enzyme linked immunosorbent assay (ELISA) in patients with oral malignancy, oral potentially malignant lesions, and control subjects to evaluate the potential of CYFRA21-1 as a diagnostic marker for malignant transformation in potentially malignant oral mucosal lesions.
This prospective, randomized, open label study will enroll patients with neovascular AMD who are naïve to anti-VEGF therapy or have not received intravitreal anti-VEGF therapy for the previous 3 months. Patients will be randomized in two treatment arms for 3 months: - Study arm 1: Three monthly injections of 0.5mg Ranibizumab - Study arm 2: Three monthly injections of 0.5mg Conbercept Blood sample (plasma/serum) will be collected at baseline (pre-dose), 3h post-in...
Randomised study comparing two pneumococcal vaccination strategies in HIV-infected adults with moderate immunossupression (CD4 between 200 and 500 cells/uL and viral load under 5logs), one with conjugated heptavalent vaccine(Prevenar, Wyeth-Lederle) followed by polysaccharide vaccine 4 weeks after (Aventis-Pasteur), and two with one dose of polysaccharide vaccine. Determination of secondary effects related to both vaccines and determination of antibody concentration (ELISA) and...
Eighty-eight pregnant women and their newborns were enrolled in a cross-sectional study. Maternal serum 25-OHD was measured by ELISA
In a equivalence analysis, we determined whether IL-6 can be assessed using a new densitometric point-of-care (POC) assay (turn-around -time: 20 minutes).IL-6 measurements were compared to test results obtained with conventional ELISA analysis
One striking observation is that a large portion of the inter-person variation in serum 25-hydroxyvitamin D (25(OH)D) levels is unexplained. In vitro and in vivo studies indicate vitamin D synthesizing and metabolizing enzymes are Mg-dependent. Magnesium (Mg) supplementation substantially reversed the resistance to vitamin D treatment in patients with magnesium-dependent vitamin-D-resistant rickets. We reported in 2013 from observational studies conducted in the general US popu...
For a long time, culture was the only way to detect Campylobacter. It appears that rapid immunochromatographic tests (ICT) have detected more positive cases compared to culture, ELISA and molecular tests. The aim of our study is to evaluate the specificity of the ICT which are really interesting tools to use since they allow a diagnosis in about 15 min, in comparison to different methods of detection even serology.
Evaluating the additional value of Macrophage Migration Inhibitory factor (MIF) in cardiovascular diseases when assessed in clinical routine.
The purpose of the study is to determine vitamin D (VD) levels and upper respiratory tract infections (URTI) morbidity among elite athletes engaged in water sports in Uzbekistan. Serum levels of 25(OH) VD and TNF-α, IFN-γ, IL-4 and IL-6 will be detected by ELISA technique among elite athletes and control population in spring and autumn.
vitamin D may have multiple functions, one of them is modulating reproductive processes and the reproductive role of vitamin D is highlighted by expression of the vitamin D receptors in testis, male reproductive tract and sperms
This case-control study was conducted on 90 patients who were equally divided into two groups. Group 1 included 45 patients with HCV-related chronic liver disease without clinical or radiological evidence of HCC (control group), and Group 2 included 45 patients diagnosed to have HCC by Triphasic abdominal CT (patient group). Serum AFP and GP73 were measured using ELISA technique
