Introduction: Several lunar highland meteorites were found in the Dhofar region of Oman. Here we report the first data on the petrography and mineralogy of four new lunar stones, Dhofar 304, 305, 306 and 307. Dh-304 was found close to Dh-025 and 301, whereas Dh-305, 306 and 307 were recovered nearby Dh-081, 280, 302 and 303. The new meteorites are moderately weathered, impact-melt breccias. No ...

The safety and clinical utility of repeated administrations of 111In-ZCE 025 were evaluated in 25 patients who have undergone colorectal carcinoma resection. Fifteen patients were clinically and radiologically free of recurrences and asymptomatic while 10 had rising CEA and/or symptoms. We repeatedly imaged the patients following intravenous administrations of 40 mg ZCE 025, every 4 to 6 mo. Si...

OBJECTIVE To analyse the outcomes of laparoscopic versus open repair for perforated peptic ulcers (PPU). METHODS All patients undergoing PPU repair between January 2002 and March 2012 were included in the study. Demographic characteristics, operation time, complications, and length of hospital stay were evaluated. RESULTS Two hundred and twelve patients (median age, 49 years) were included,...

Frequent itemset mining was initially proposed and has been studied extensively in the context of association rule mining. In recent years, several studies have also extended its application to the transaction (or document) classification and clustering. However, most of the frequent-itemset based clustering algorithms need to first mine a large intermediate set of frequent itemsets in order to...

We reviewed 47 prospective studies of recurrence of pulmonary tuberculosis (TB) after cure to assess the influence of human immunodeficiency virus (HIV) infection and rifampin treatment. Multivariate regression revealed that the recurrence rate for HIV-uninfected persons increased with decreasing duration of therapy: it was 1.4 cases per 100 person-years for recipients of >or=7 months of rifamp...
