Purpose Determine which posterior uveal melanoma (PUM) size classification with three categories has the best prognostic discrimination. Methods Single-institution study of 424 consecutive patients with PUM. The tumor's largest basal diameter (LBD), smallest basal diameter (SBD), and thickness (TH) were estimated by fundus mapping and ultrasonography. Tumors were assigned to "small," "medium,...
Bessenrodt and Ono initially found the strict log-subadditivity of partition function p(n), that is, $$p(a+b)< p(a)p(b)$$ for $$a,b>1$$ $$a+b>9$$ . Many other important statistics are proved to enjoy similar properties. Lovejoy introduced overpartition rank as an analog Dyson’s partitions from q-series perspective. Let $${\overline{N}}(a,c,n)$$ denote number overpartitions with congruent a modu...
In this paper, we consider the problem of two sided hypothesis testing for the parameter of coefficient of variation of an inverse Gaussian population. An approach used here is the modified signed log-likelihood ratio (MSLR) method which is the modification of traditional signed log-likelihood ratio test. Previous works show that this proposed method has third-order accuracy whereas the traditi...
PURPOSE To validate whether FAM70B, which was found in our micro-array profiling as a prognostic marker for cancer survival, could accurately predict prognosis in patients with muscle-invasive bladder cancer (MIBC). MATERIALS AND METHODS A total of 124 patients with MIBC were enrolled in this study. The FAM70B expression level was analyzed by real-time polymerase chain reaction by using RNA f...
PURPOSE Elevated serum concentration of fibrinogen and decreased serum concentration of albumin have been reported to be markers of elevated systemic inflammation. We attempted to investigate the prognostic influence of preoperative fibrinogen to albumin ratio (FAR) for breast cancer. METHODS Data from 793 consecutive primary breast cancer patients were retrospectively analyzed. Serum levels ...
BACKGROUND We sought to examine the effect of different conduits on the progression of atherosclerosis in previously revascularized coronary territories. METHODS Between 1995 and 2010, 4,960 patients were discharged alive after primary isolated coronary artery bypass grafting (CABG) with a left internal thoracic artery (LITA) conduit and additional conduits as needed: radial artery (RA) or sa...
Between 1966 and 2001, 1254 patients underwent excision of a bone tumour with endoprosthetic replacement. All patients who had radiotherapy were identified. Their clinical details were retrieved from their records. A total of 63 patients (5%) had received adjunctive radiotherapy, 29 pre-operatively and 34 post-operatively. The mean post-operative Musculoskeletal Tumor Society scores of irradiat...
test day milk records of a holstein dairy farm collected during years 2004 to 2006 on 142 cows in the 1st lactation vs. 140 cows in the 2nd lactation were used in this research. there were real milk yields of cows available in each part of lactation in this farm making it possible to compare functions based on the new criteria (squared error of estimation). five functions were compared to estim...
