AIM OF THE STUDY To evaluate the diagnostic capacity of tele-cervicography for the detection of cervical neoplasia as an adjunctive test with Papanicolaou (Pap) smears. MATERIAL AND METHODS Pap smear and tele-cervicography were performed on each subject. Histologic results were obtained for all patients. RESULTS Of the 863 females who had a tele-cervigram, 252 (29.2%) had a positive result....

background: gliomas are the most common primary neoplasms of the central nervous system. relative cerebral blood volume (rcbv) could estimate high-grade gliomas computed with dynamic susceptibility contrast mr imaging which it is artificially lowered by contrast extravasation through a disrupted blood-brain barrier. objectives: our intent was to clarify the usefulness of diffusion-weighted magn...

BACKGROUND AND PURPOSE The usefulness of pharmacokinetic parameters for glioma grading has been reported based on the perfusion data from parts of entire-tumor volumes. However, the perfusion values may not reflect the entire-tumor characteristics. Our aim was to investigate the feasibility of glioma grading by using histogram analyses of pharmacokinetic parameters including the volume transfer...

UNLABELLED Measurement of nitroglycerine-induced vasodilation has been performed to differentiate endothelium-dependent vasodilation from endothelium-independent vasodilation as a control test for flow-mediated vasodilation (FMD). Recently, nitroglycerine-induced vasodilation per se has been reported to be a useful marker of the grade of atherosclerosis. The present study aimed to evaluate the ...

Estimation of ore reserves is one of the most critical aspects of mining geology. The accurate assessment of the tonnage and grade of run of mine may be the difference between a healthy profitable operation and an expensive early mine closure. The first step in ore reserve estimation is to determine the boundary of ore body or ore/waste contacts. This paper presents a specific mining applicatio...

this research was conducted at torogh agricultural research station in khorasan-e razavi province to determine the impact of irrigation cutoff at different growth stages and percentage of water use on the yield and water use efficiency (wue) of wheat cultivars using sprinkler irrigation. the study was done from 2006-2008. the experimental design was a randomized complete block design with a str...

PURPOSE The purpose of this study was to estimate the diagnostic accuracy of relative cerebral blood volume (rCBV) measurement in preoperative grading and differentiation of solitary intra-axial malignant brain tumors. METHODS Thirty-six low-grade glial tumors (LGGTs), 22 high-grade glial tumors (HGGTs), and 17 metastases (METs) were prospectively evaluated by MR imaging and standard dynamic ...

OBJECTIVE To evaluate the pattern of post-operative bile duct injuries and their subsequent endoscopic management. METHODS The prospective, non-randomised, cross-sectional study was conducted at the endoscopic suite of Surgical Unit-IV of the Civil Hospital, Karachi, over a period of three years. A total of 97 patients were included in the study. Post-procedure patients were followed up for r...

BACKGROUND Multi-step testing might enhance performance of the prostate cancer diagnostic pipeline. Using PSA >1 ng/ml for first-line risk stratification and the Stockholm 3 Model (S3M) blood-test >10% risk of Gleason Score > 7 prostate cancer to inform biopsy decisions has been suggested. We aimed to determine the effects of changing the PSA cutoff to perform reflex testing with S3M and the su...

We study the determination of liquidity provision in the single-name credit default swap (CDS) market as measured by the number of distinct dealers providing quotes. We find that liquidity is concentrated among large obligors and those near the investment-grade/speculative-grade cutoff. Consistent with endogenous liquidity provision by informed financial institutions, more liquidity is associat...
