PROBLEM: Prostate cancer is one of the most common complex diseases with high leading cause of death in men. Identifications of prostate cancer associated genes and biomarkers are thus essential as they can gain insights into the mechanisms underlying disease progression and advancing for early diagnosis and developing effective therapies.', 'In this study, we presented an integrative analysis of gene expression profiling and protein interaction network at a systematic level to reveal candidate disease-associated genes and biomarkers for prostate cancer progression. At first, we reconstructed the human prostate cancer protein-protein interaction network (HPC-PPIN) and the network was then integrated with the prostate cancer gene expression data to identify modules related to different phases in prostate cancer. At last, the candidate module biomarkers were validated by its predictive ability of prostate cancer progression.', 'Different phases-specific modules were identified for prostate cancer. Among these modules, transcription Androgen Receptor (AR) nuclear signaling and Epidermal Growth Factor Receptor (EGFR) signalling pathway were shown to be the pathway targets for prostate cancer progression. The identified candidate disease-associated genes showed better predictive ability of prostate cancer progression than those of published biomarkers. In context of functional enrichment analysis, interestingly candidate disease-associated genes were enriched in the nucleus and different functions were encoded for potential transcription factors, for examples key players as AR, Myc, ESR1 and hidden player as Sp1 which was considered as a potential novel biomarker for prostate cancer.

SOLUTION: Does integrative analysis reveal disease-associated genes and biomarkers for prostate cancer progression?

PROBLEM: Unintentional injuries are the leading cause of death in children, and falls are the most common type of unintentional injury in the US. The incidence of falls from windows, a common cause of death in urban areas, has not been described outside major cities such as New York and Chicago, and rates in urban and suburban areas have not been compared.', 'To estimate the incidence and identify the population at risk for falls from windows among children in Hamilton County, Ohio.', "Retrospective case series identified using Cincinnati Children's Hospital Medical Center (CHMC) Trauma Registry.", 'Hamilton County, Ohio, which has urban and nonurban areas.', 'Children less than 15 years old residing in Hamilton County, Ohio, presenting to CHMC in Cincinnati, Ohio, after a fall from a window between January 1, 1991, and December 31, 1997.', 'Annual incidence by age, race, gender, and residence of those who fell from windows.', 'Over the 7-year study period, 86 (6.3%) of 1,363 falls were from windows. The mortality rate for falls from windows was 4.7%, compared to 0.07% for all other falls presenting to CHMC (P<.0001). Children 0-4 years old had a higher rate of falls than children aged 5-14 (14.6/100,000 vs. 2.0/100,000) (P<.0001). Males were twice as likely to fall as females (P<.016), and black children were three times more likely to fall than non-black children (P<.002). The incidence of falls in the city of Cincinnati was four times that of the non-urban area (P<.0002).

SOLUTION: Does childhood injuries and deaths due to fall from windows?

PROBLEM: This experimental study was undertaken to determine whether pretreatment with statins would enhance myocardial protection and minimize ischemic injury during revascularization of acutely ischemic myocardium.', 'In 20 pigs the second and third diagonal arteries were occluded for 90 minutes, followed by 45 minutes of blood cardioplegic arrest and 180 minutes of reperfusion. Ten pigs received atorvastatin (40 mg orally every day) for 21 days before surgical intervention; 10 others received no statins. Ischemic damage was assessed on the basis of the need for cardioversions for ventricular arrhythmias, regional wall-motion scores (4 = normal to -1 = dyskinesia) were determined by means of 2-dimensional echocardiography, endothelial function was assessed on the basis of bradykinin-induced coronary artery relaxation, and infarct size was calculated by determining the area of necrosis to the area of risk by means of histochemical staining. Results are given as means +/- SE.', 'Statin-treated animals required fewer cardioversions (0.11 +/- 0.01 vs 2.87 +/- 0.20, P =.0001), had improved wall-motion scores (2.81 +/- 0.10 vs 1.52 +/- 0.08, P =.01), had lower infarct size (21% +/- 2% vs 41% +/- 2%, P =.0001), and had more complete coronary artery relaxation (34% +/- 5% vs 8% +/- 4%, P =.01). Total serum cholesterol levels were similar between the groups (62 +/- 5 mg/dL for statin-treated animals vs 68 +/- 5 mg/dL for non-statin-treated animals, P =.30).

SOLUTION:
Does pretreatment with statins enhance myocardial protection during coronary revascularization?
