Numerous Bladder Stones.
An 83-year-old man with benign prostatic hyperplasia and several comorbid conditions presented with irremovable urethral Foley catheter. Plain abdominal X-ray revealed a bladder full of stones. The patient had bilateral hydronephrosis and elevated serum Creatinine level. Open vesicolithotomy was done and more than 720 stones in various shapes and sizes was removed. After removal of stone, Creat...
متن کاملMg2+ ions: do they bind to nucleobase nitrogens?
Given the many roles proposed for Mg2+ in nucleic acids, it is essential to accurately determine their binding modes. Here, we surveyed the PDB to classify Mg2+ inner-sphere binding patterns to nucleobase imine N1/N3/N7 atoms. Among those, purine N7 atoms are considered to be the best nucleobase binding sites for divalent metals. Further, Mg2+ coordination to N7 has been implied in several ribo...
متن کاملNowcasting with Numerous Candidate Predictors
The goal of nowcasting, or “predicting the present,” is to estimate up-to-date values for a time series whose actual observations are available only with a delay. Methods for this task leverage observations of correlated time series to estimate values of the target series. This paper introduces a nowcasting technique called FDR (false discovery reduction) that combines tractable variable select...
متن کاملNumerous Transitions of Sex Chromosomes in Diptera
Many species groups, including mammals and many insects, determine sex using heteromorphic sex chromosomes. Diptera flies, which include the model Drosophila melanogaster, generally have XY sex chromosomes and a conserved karyotype consisting of six chromosomal arms (five large rods and a small dot), but superficially similar karyotypes may conceal the true extent of sex chromosome variation. H...
متن کاملA Review of Numerous Parallel Multigrid Methods
Multigrid methods originated earlier this century, in the personnel computing era. Someone who needed to compute an approximation to the solution of a partial di erential equation during that era would ll a room with people. After using very simple mechanical calculators to compute parts of the approximation, these people would pass their parts to the other people in the room who needed them. E...
