In this article, I employ a linear differentiated demand model to demonstrate the risks associated with using market shares as a proxy for diversion ratios when calculating the unilateral effects of a merger. In particular, when pro-rata market shares are not adjusted for recapture rates, the estimated diversion ratios are significantly higher than the true diversion ratios. As a result, the es...

Urinary diversion is performed on a regular basis in urological practice. Surgeons tend to underestimate the metabolic effects of any type of diversion. From the patient's perspective, diarrhea is the most bothersome complaint after urinary diversion. This might be accompanied by malabsorption syndromes, such as vitamin B12 deficiency. Electrolyte abnormalities can occur frequently such as hype...

The Nueces River is the primary source of freshwater inflow to Corpus Christi Bay and virtually the only source of freshwater inflow to the Nueces Delta. In association with reservoir development and operation within the Nueces Basin, the magnitude of freshwater inflow has been greatly reduced since 1958. Continually increasing salt concentrations in the soil and water have compromised the func...

a 57-year-old male with history of prostatectomy, cyctectomy, cecal urinary diversion for invasive prostate cancer and with a recent rise in psa level, was referred for bone scintigraphy to rule out osseous metastatic disease. an interesting finding was abnormal tracer accumulation throughout the large bowel, which was proved to be due to urinary diversion.

Several Emergency Medical Service (EMS) agencies across the US have demonstrated that the time spent by EDs on ambulance diversion can be reduced by implementing community-wide policies that restrict the duration and frequency of diversion episodes. However, the mechanisms through which these reductions materialize are not well understood. EDs can respond to such restrictions by improving their...

Brain aneurysms are abnormal ballooning of intracranial arteries which when left untreated may result in fatal outcome for the patients. Neurovascular stents have been used extensively in stent-assisted coiling treatment of aneurysms. Treatment with flow diverters (low porosity, fine-mesh stents) is used for complicated aneurysm geometries not amenable to coiling. Angiographic analysis with mat...

Urinary diversion after extirpative surgery of the bladder is done by various methods. Conduit urinary diversion is the most commonly practiced method of urinary diversion. It is relatively easy to perform and has a lower complication rate than other forms of diversion, e.g., orthotopic neobladder and continent cutaneous urinary diversion. Urolithiasis is a known and common complication of urin...

BACKGROUND/AIMS Diversion colitis is the inflammation of the excluded segment of the colon in patients undergoing ostomy. It has been suggested that a change in colonic flora may lead to colitis; however, direct evidence for this disease progression is lacking. The aim of this study was to evaluate the relationship between the severity of diversion colitis and the composition of colonic bacteri...
