Normal iron homeostasis is a finely balanced system that reflects iron absorption, loss and utilization. The body has no mechanism for the active excretion of iron, so body iron levels are controlled at the point of absorption in the small intestine. Disturbances in this equilibrium, such as those leading to enhanced a... |

INTRODUCTION |
To determine the significance of bladder trabeculations seen on preoperative cystoscopy prior to midurethral sling surgery with respect to lower urinary tract symptoms and sling outcomes. |
MATERIALS AND METHODS |
This retrospective study included women with preoperative cystoscopy who underwent midurethral slings for urinary incontinence from 2006-2009. Cystoscopic findings of bladder trabeculations, as well as pre and postoperative urinary symptoms were recorded. Patients with and without bladder trabeculations were compared w... |
RESULTS |
Of the 241 women included in the study, 14.9% had trabeculations on preoperative cystoscopy. At baseline, women with trabeculations were more likely to be older (64.8 years versus 57.8 years, p < 0.01), and have lower mean maximum cystometric capacity (341 mL +/- 136 versus 436 mL +/- 148, p < 0.01), compared to those ... |
CONCLUSIONS |
Preoperative cystoscopic bladder trabeculations are associated with significantly higher rate of midurethral sling failure. Trabeculations were not associated with pre or postoperative lower urinary tract symptoms.Protocols Wireless for Ad Hoc Wireless Networks : Classifications of Protocols and A review of Table Drive... |

We consider the problem of testing bipartiteness in the adjacency matrix model. The best known algorithm, due to Alon and Krivelevich, distinguishes between bipartite graphs and graphs that are /spl epsi/-far from bipartite using 0(1//spl epsi//sup 2/) queries. We show that this is optimal for non-adaptive algorithms, ... |

BACKGROUND |
It has been known that platelet activating factor receptors (PAFR) may mediate many acute pathological responses and that PAFR antagonist Ginkgolide B (GB) possesses multiple effects, but the actions of GB on PAFR affinity and mitochondrial respiration in the ischemic neuron were unclear until now. This study explored ... |
METHODS |
Thrombotic cerebral ischemia in tree shrews was induced by a photochemical reaction; changes in the regional cerebral blood flow (rCBF, using (99m)Tc tracer technique), the brain water content (specific gravimetric method), PAFR (3H-labelled PAF assay), the respiratory control rate (RCR), the phosphorus-oxygen (P/O) ra... |
RESULTS |
There were high affinity and low affinity sites for PAFR on the tree threws' brain cell membranes. The varying-affinity PAFR binding sites, the respiration state III, the state IV, RCR, the P/O ratio of the mitochondria, and the rCBF all decreased markedly (respectively, P < 0.01 and P < 0.05), but the water content in... |
CONCLUSIONS |
The activation of the PAFR may play an important role in the inhibition of the mitochondrial respiration and the induction of neuronal damage after cerebral thrombosis; however, GB possesses neuroprotective effects by improving mitochondrial metabolism.Generating a Test Strategy with Bayesian Networks and Common Sense |
