AIM To explore the natural history of covert hepatic encephalopathy (CHE) in absence of medication intervention. METHODS Consecutive outpatient cirrhotic patients in a Chinese tertiary care hospital were enrolled and evaluated for CHE diagnosis. They were followed up for a mean of 11.2 ± 1.3 mo. Time to the first cirrhosis-related complications requiring hospitalization, including overt HE (O...

Deadlocks are a common error in programs with lock-based concurrency and are hard to avoid or even to detect. One way for deadlock prevention is to statically analyze the program code to spot sources of potential deadlocks. Often static approaches try to confirm that the lock-taking adheres to a given order, or, better, to infer that such an order exists. Such an order precludes situations of c...

The recall of CD8(+) T-cell memory established by infecting H-2(b) mice with an H1N1 influenza A virus provided a measure of protection against an extremely virulent H7N7 virus. The numbers of CD8(+) effector and memory T cells specific for the shared, immunodominant D(b)NP(366) epitope were greatly increased subsequent to the H7N7 challenge, and though lung titers remained as high as those in ...

There are two common types of solution methods for solving simple integrals: using integration constants or using limits of integration. We use the resources framework to model student solution methods. Preliminary results indicate both problematic and meaningful intersections of physical meaning and mathematical formalism when solving linked integrals. Students solving separable first order di...

assess duration of action, patients were challenged with allergen 16 hours after dosing. The percentage of eyes with zero itching in both studies was assessed at 3 minutes post allergen challenge. Results: The percentage of eyes with zero itch at the 3 minutes timepoint after the onset of action allergen challenge was 60.0% for OLO-treated eyes compared with 5.9% for vehicle-treated eyes (P , ....

BACKGROUND The purpose of this study was to acquire nationwide data on the management and outcome of laryngeal squamous cell carcinoma (SCC) in Finnish university hospitals over a 5-year posttreatment follow-up. METHODS All records of patients diagnosed and treated for primary laryngeal SCC during 2001 to 2005 were reviewed. RESULTS Three hundred sixty-six patients with laryngeal cancer wer...

BACKGROUND Salivary gland tumors (SGT) are one of the most complex human neoplasms, demonstrating variations in their clinicopathological profile related to racial and geographic differences. Few studies with large samples have been reported in Iran. We here investigated a large group of patients in southern Iran. MATERIALS AND METHODS In this retrospective study, all cases of primary epithel...
