In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Example Input: Context: Protein kinase D (PKD or PKD1) is a serine/threonine protein kinase that has been shown to play a role in a variety of cellular processes; however, the function of PKD1 in the skin has not been fully investigated. The balance between proliferation and differentiation processes in the predominant cells of the epidermis, the keratinocytes, is essential for normal skin function.', 'To investigate the effect of PKD1 deficiency on proliferation and differentiation of epidermal keratinocytes.', 'We utilized a floxed PKD1 mouse model such that infecting epidermal keratinocytes derived from these mice with an adenovirus expressing Cre-recombinase allowed us to determine the effect of PKD1 gene loss in vitro. Proliferation and differentiation were monitored using qRT-PCR, Western blot, transglutaminase activity assays, [3H]thymidine incorporation into DNA and cell cycle analysis.', 'A significant decrease in PKD1 mRNA and protein levels was achieved in adenoviral Cre-recombinase-infected cells. Deficiency of PKD1 resulted in significant increases in the mRNA and protein expression of various differentiation markers such as loricrin, involucrin, and keratin 10 either basally and/or upon stimulation of differentiation. PKD1-deficient keratinocytes also showed an increase in transglutaminase expression and activity, indicating an anti-differentiative role of PKD1. Furthermore, the PKD1-deficient keratinocytes exhibited decreased proliferation. However, PKD1 loss had no effect on stem cell marker expression.\Question: Does protein kinase D1 deficiency promote differentiation in epidermal keratinocytes?
Example Output: Cre-recombinase-mediated knockdown represents an additional approach demonstrating that PKD1 is an anti-differentiative, pro-proliferative signal in mouse keratinocytes.

Example Input: Context: To investigate patterns of detection and variables associated with early diagnosis of melanoma in a population at intermediate melanoma risk.', 'Survey.', 'Hospital and university centers belonging to the Italian Multidisciplinary Group on Melanoma.', 'Eight hundred sixteen patients who were consecutively diagnosed as having melanoma and treated at 11 participating centers.', "Relationship between patterns of detection and patient's and physician's delay with melanoma thickness, assessed by multivariate analysis.", "A statistically significant association with early diagnosis was found for female sex (odds ratio [OR] for a lesion >1 mm in thickness, 0.70; 95% confidence interval [CI], 0.50-0.97), higher educational level (OR, 0.44; 95% CI, 0.24-0.79), residence in northern and central Italy (compared with southern Italy) (OR, 0.44; 95% CI, 0.30-0.65 and OR, 0.24; 95% CI, 0.15-0.37, respectively), and the habit of performing a skin self-examination (OR, 0.65; 95% CI, 0.45-0.93). When adjusted for all the previously mentioned variables, only melanoma detection made by a dermatologist, maybe incidentally, was associated with a statistically significant additional effect on early diagnosis (OR, 0.45; 95% CI, 0.28-0.73). No significant effect of anatomical site (trunk compared with other sites: OR, 0.83; 95% CI, 0.59-1.17), presence of atypical nevi (OR, 0.78; 95% CI, 0.52-1.17), and patient's delay (>3 months compared with < or =3 months: OR, 1.12; 95% CI, 0.78-1.60) was found.\Question: Are dermatologist detection and skin self-examination associated with thinner melanomas : results from a survey of the Italian Multidisciplinary Group on Melanoma?
Example Output: Future melanoma early diagnosis strategies should adequately stress the role of skin self-examination among the adult population, and should recommend that dermatologists perform a total skin examination to identify suspect lesions (such an examination should also be performed during consultations for other reasons).

Example Input: Context: Extracorporeal membrane oxygenation (ECMO) support is often required in the management of perioperative congenital heart surgery (CHS) patients. However, 24-hour in-hospital congenital cardiac surgical coverage (24-CCSC) is not available at all institutions. The purpose of this study is to evaluate the effect of 24-CCSC on perioperative ECMO outcomes in CHS patients.', "An institutional review board approved, retrospective review of 128 perioperative CHS ECMO patients at a single, quaternary care children's hospital between January 2003 and December 2012 was performed. Primary endpoints evaluated were mortality in children supported with ECMO after undergoing cardiac surgery and ECMO-related morbidity after initiation of 24-CCSC with advanced congenital cardiac surgical fellows. Patients were divided into 2 groups based on whether 24-CCSC was absent (cohort 1: January 2003 to July 2007) or present (cohort 2: August 2007 to December 2012) at the time of ECMO management.", 'The surgical procedures performed were similar in both cohorts based on STAT Mortality Categories (5 Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery Congenital Heart Surgery Mortality Categories). The overall mortality rate in children supported with ECMO after undergoing cardiac surgery was 53%. This mortality was significantly reduced from 68% to 43% (p= 0.007) with24-CCSC. Multivariate logistic regression analysis revealed that 24-CCSC (p= 0.009) and lower STAT Mortality Category (p= 0.042) were independent predictors of operative survival. Cardiac arrhythmias (36% to 16%; p= 0.012) and pulmonary complications (32% to 8%; p < 0.001) were significantly reduced with 24-CCSC.\Question: Does twenty-four hour in-hospital congenital cardiac surgical coverage improve perioperative ECMO support outcomes?
Example Output:
The presence of 24-CCSC significantly decreased the rate of mortality in children supported with ECMO after undergoing cardiac surgery, as well as cardiac arrhythmias and pulmonary complications for perioperative CHS patients receiving ECMO support. This study demonstrates that CHS programs would benefit from 24-CCSC in the care of this critically ill patient population.
