Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Cadherins are calcium-dependent cell-to-cell adhesion glycoproteins playing a critical role in the formation and maintenance of normal tissue architecture. In normal mammary gland, E-cadherin is expressed by luminal epithelial cells, while P-cadherin is restricted to myoepithelial cells. Changes in the expression of classical E- and P-cadherins have been observed in mammary lesions and related to mammary carcinogenesis. P-cadherin and E-cadherin expressions were studied in a series of feline normal mammary glands, hyperplastic/dysplastic lesions, benign and malignant tumours by immunohistochemistry and double-label immunofluorescence.', 'In normal tissue and in the majority of hyperplastic/dysplastic lesions and benign tumours, P-cadherin was restricted to myoepithelial cells, while 80% of the malignant tumours expressed P-cadherin in luminal epithelial cells. P-cadherin expression was significantly related to high histological grade of carcinomas (p <0.0001), tumour necrosis (p = 0.001), infiltrative growth (p = 0.0051), and presence of neoplastic emboli (p = 0.0401). Moreover, P-cadherin positive carcinomas had an eightfold likelihood of developing neoplastic emboli than negative tumours. Cadherins expression profile in high grade and in infiltrative tumours was similar, the majority expressing P-cadherin, regardless of E-cadherin expression status. The two cadherins were found to be co-expressed in carcinomas with aberrant P-cadherin expression and preserved E-cadherin.
Is aberrant P-cadherin expression associated to aggressive feline mammary carcinomas?

Diarrhea is the third leading infectious cause of death worldwide and is estimated to be responsible for approximately 2 million deaths a year. While many infectious causes of diarrhea have been established, approximately 40% of all diarrhea cases are of unknown etiology. In an effort to identify novel viruses that may be causal agents of diarrhea, we used high throughput mass sequencing to analyze stool samples collected from patients with acute diarrhea.', "Sequences with limited similarity to known picornaviruses were detected in a stool sample collected in Australia from a child with acute diarrhea. Using a combination of mass sequencing, RT-PCR, 5' RACE and 3' RACE, a 6383 bp fragment of the viral genome was sequenced. Phylogenetic analysis demonstrated that this virus was highly divergent from, but most closely related to, members of the genus Kobuvirus. We have tentatively named this novel virus klassevirus 1. We also detected klassevirus 1 by RT-PCR in a diarrhea specimen collected from a patient in St. Louis, United States as well as in untreated sewage collected in Barcelona, Spain.
Is klassevirus 1 , a previously undescribed member of the family Picornaviridae , globally widespread?

To evaluate the efficacy and safety of the combination of ICE (ifosfamide 1.5 g m(-2), carboplatin 100 mg m(-2) and etoposide 150 mg m(-2), days 1-4, q 28 days, G-CSF 5 microg kg(-1) starting from day 6) alone and in combination with regional hyperthermia (RHT) in soft tissue sarcoma (STS) refractory to previous standard doxorubicin-ifosfamide-based chemotherapy.', 'Twenty patients with advanced STS of different histological sub-types were treated with the ICE regimen with 13 patients receiving additional RHT. A median of four courses of ICE were administered with RHT on days 1 and 3 (60 min, T(max) 42 degrees C).', 'The objective response rate was 20%, with four partial responses (all treated with hyperthermia). In addition, two patients showed mixed responses and five patients stable disease. After a median follow-up time of 15 months, median time to progression was 6 months. Progression free rate estimates were 60% and 45% at 3 and 6 months, respectively. Median overall survival for all patients was 14.6 months.

Is ifosfamide , carboplatin and etoposide ( ICE ) as second-line regimen alone and in combination with regional hyperthermia active in chemo-pre-treated advanced soft tissue sarcoma of adults?
