The human granulocyte alloantigen NB1, recently clustered as CD177, is heterogenously expressed on neutrophils of 88-97% of healthy individuals. Since its molecular nature has remained unknown, we isolated NB1 glycoprotein from granulocyte lysate by immunoaffinity chromatography. MALDI-TOF mass spectrometry identified a 50,556 Da glycoprotein which was reduced to 43,069 Da after removal of N-linked carbohydrates. Following N-terminal amino acid sequencing and NB1-specific primer construction, rapid amplification of cDNA ends PCR yielded a 1,614-bp cDNA for NB1. COS-7 cells transfected with the cDNA expressed immunoreactive NB1 glycoprotein. A 1,311-bp sequence was identified to be the entire coding region. The 5' and 3' untranslated regions consist of 27 bp and 276 bp, respectively. The open reading frame codes for 437 amino acids of which the first 21 form the signal peptide. The remaining 416 residues form a N-terminal extracellular protein with two cysteine-rich domains, three N-linked glycosylation sites and short transmembrane and cytoplasmic segments including a glycosyl-phosphatidylinositol attachment (omega) site. Database searches revealed homology to Ly-6 (uPAR) domain, suggesting that NB1 belongs to urokinase plasminogen activator receptor/CD59/Ly-6 snake toxin superfamily. 相似文献

Purpose
We sought to evaluate prevalence, age-adjusted distribution, and impact of single and multiple high- and low-risk human papillomavirus (HPV) subtypes and their associations with cervical lesions.Methods
Data were extracted from 11,224 women who underwent routine screening of HPV genotyping and liquid-based cytology co-testing. Fifteen high-risk (HR) and six low-risk (LR) HPV types were genotyped.Results
Overall HPV prevalence was 10.7 %, and young women (under 21 years old) harbored highest HPV infection rate (40.38 %). The rate declined in old women 9.49 % (age 30–49) and 6.89 % (age 50 and above). Normal cytology had lowest HPV (5.66 %) compared to low-grade (60.49 %), high-grade (71.96 %) squamous intraepithelial lesions (LSIL and HSIL) and squamous cell carcinoma SCC (86.9 %). LR HPV subtypes were absent in SCC and were consistently lower than HR HPV in LSIL (6.74 vs. 33.54 %) and HSIL (2.12 vs. 51.32 %). Multiple HPV infection was more frequent in young women under 30 years old (10 %) than older women (2 %) and in LSIL (20.2 %), HSIL (18.5 %) than SCC (4.4 %). HR HPV 52, 16, 18, and 58 were the most frequent subtypes in normal, LSIL, and HSIL. Greater or equal proportion of HPV 16, 18, 45, and 52 was found in SCC compared to normal cytology (SCC/normal ratios 4.8, 1.2, 1.6, and 1.7). While important in LSIL and HSIL, HPV58 was not detected in SCC.Conclusion
Taken together, identification of these HPV types, especially HPV 16, 18, 45, and 52, and their associated cervical lesions may improve cervical cancer preventive strategies in Indonesia.53.

The present study was performed to compare the bioavailability of two perindopril erbumine (CAS 107133-36-8) 4 mg tablet formulations (test formulation and reference formulation). This study was a randomized, single-blind, two-period, two-sequence cross-over study which included 20 healthy adult male and female subjects under fasting conditions. In this study, one subject withdrew from the study and one reserve subject did not appear at both periods. The pharmacokinetic parameters were assessed based on the concentrations of perindopril (CAS 82834-16-0) and perindoprilat (CAS 95153-31-4) because perindopril has litte pharmacologic activity until hydrolized in the liver into its active metabolite, perindoprilat. The blood samples from 18 subjects were analyzed for plasma concentrations of perindopril and perindoprilat. In each of the two study periods (separated by a washout of three weeks) a single dose of test or reference drug was administered. Plasma concentrations of the drug were determined by LC-MS/MS method. The pharmacokinetic parameters assessed in this study were area under the plasma concentration-time curve from time zero to 192 h (AUC), area under the plasma concentration-time curve from time zero to infinity (AUCinf), the peak plasma concentration of the drug (Cmax time needed to achieve the peak plasma concentration (tmax), and the elimination half-life (t(1/2)). The geometric mean ratios (90% CI) of the test drug/reference drug for perindopril and perindoprilat were 106.59% (92.97-122.20%) and 100.56% (94.11-107.46%) for AUC,, 106.64% (93.39-121.77%) and 100.88% (95.30-106.80%) for AUCinfo, and 101.23% (87.39-117.27%) and 99.30% (90.42-109.05%) for Cmax, respectively. The 90% confidence intervals calculated for AUCt and Cmax of perindopril and perindoprilat were within the standard bioequivalence range (80-125% for AUC and Cmax). It was concluded that the two perindopril erbumine tablets (test and reference drug) were bioequivalent in terms of the rate and extent of absorption. 相似文献

Objective
To identify factors that may contribute to poor sensitivity of anal cytology in contrast to the sensitivity of anoscopy in heterosexual women.Methods
We analyzed 324 patients with biopsy confirmed diagnosis of genital intraepithelial neoplasia (either vulva, vaginal, or cervical) from 2006 to 2011 who underwent both anal cytology and anoscopy. Cytology, anoscopy, and biopsy results were recorded. Biopsy specimens underwent independent analysis for quality of specimen. Also, biopsy specimens were analyzed for characteristics that may contribute to correlation, or lack thereof, between anal cytology and anoscopic directed biopsy.Results
133 (41%) patients had abnormal anoscopy and underwent directed biopsy. 120 patients with normal anal cytology had anoscopy directed biopsies, resulting in 58 cases of AIN (sensitivity 9.4%; 0.039-0.199). This cohort was noted to have extensive keratosis covering the entire dysplastic anal lesion. 18 patients yielded abnormal anal cytology. Of these patients, 13 had anoscopic directed biopsies revealing 6 with AIN and absent keratosis (specificity 88.6%; 0.78-0.95). The κ statistic for anal cytology and anoscopy was − 0.0213 (95% CI = − 0.128-0.086).Conclusion
Keratosis reduces the sensitivity of anal cytology. Furthermore, anal cytology poorly correlates with anoscopy in the detection of AIN (κ statistic = − 0.0213). 相似文献56.

BACKGROUND: To evaluate the diagnostic value of alpha-1-acid glycoprotein (AAG) and the combination with alpha-fetoprotein (AFP) in hepatocellular carcinoma (HCC) patients. METHODS: AAG was measured in serum of 65 HCC patients and 54 chronic liver diseases (CLD) patients by using proteomic approach. Sensitivity and specificity of AAG and its combination with AFP were determined and compared with AFP alone for the diagnosis of HCC. RESULTS: The expression concentration of AAG was significantly higher in HCC patients than chronic liver disease with sensitivity (77%) and accuracy (83%). Receiver operating characteristic analysis yielded the following AUC: AFP 0.750 (CI 95% 0.663-0.837), AAG 0.907 (CI 95% 0.855-0.960) and AFP+AAG 0.943 (CI 95% 0.897-0.988). At a specificity of 90%, the combination of AFP+AAG had sensitivity 89% and accuracy 90%, which was higher than sensitivity (52.3%) and accuracy (70%) when using AFP alone. CONCLUSION: The combination of AAG and AFP shows high sensitivity and improves the accuracy of HCC diagnosis. 相似文献

Platelet polymorphisms in thrombotic disorders. 总被引:7,自引:0,他引:7

Plaque rupture and/or endothelial damage lead to exposure of von Willebrand factor (VWF) and collagen which facilitate the adhesion of circulating platelets via glycoprotein (GP) GPIb-IX-V and integrin alpha2 beta1, respectively, to the damaged vessel wall. This process activates the platelets and leads to a conformational change of a second integrin alphaIIb beta3 that facilitates fibrinogen binding and platelet aggregation. Thrombin generated at the blood-plaque interface converts fibrinogen to fibrin, which stabilizes thrombus growth. Therefore, any genetic differences that might alter surface expression or activity of these receptors could influence the risk for adverse outcome as a result of the hemostatic process. In the last five years, there has been a rapid accumulation of literature concerning the relationship between genetic variations in platelet glycoproteins and risk for coronary heart disease. In this study, we have presented a comprehensive review of the impact of platelet receptor polymorphisms and thrombotic risk. 相似文献
