Impact of Virtual Reality Simulation on New Nurses' Assessment of Pediatric Respiratory Distress.

Background: Children often experience respiratory illnesses requiring bedside nurses skilled in recognizing respiratory decompensation. Historically, recognizing respiratory distress has relied on teaching during direct patient care. Virtual reality simulation may accelerate such recognition among novice nurses.

Ileocolonic Healing after Small Ileocecal Resection in Mice: NOD2 Deficiency Impairs Anastomotic Healing by Local Mechanisms.

Ileocecal resection (ICR) is frequently performed in Crohn's disease (CD). mutations are risk factors for CD. knockout (ko) mice show impaired anastomotic healing after extended ICR.

Dynamic contrast enhanced MRI of pulmonary adenocarcinomas for early risk stratification: higher contrast uptake associated with response and better prognosis.

Background: To explore the prognostic value of serial dynamic contrast-enhanced (DCE) MRI in patients with advanced pulmonary adenocarcinoma undergoing first-line therapy with either tyrosine-kinase inhibitors (TKI) or platinum-based chemotherapy (PBC).

Methods: Patients underwent baseline (day 0, n = 98), and post-therapeutic DCE MRI (PBC: day + 1, n = 52); TKI: day + 7, n = 46) at 1.5T.

In vitro pharmacological profile of PHA-022121, a small molecule bradykinin B receptor antagonist in clinical development.

PHA-022121 is a novel small molecule bradykinin B receptor antagonist, in clinical development for the treatment and prevention of hereditary angioedema attacks. The present study describes the in vitro pharmacological characteristics of PHA-022121 and its active metabolite, PHA-022484 (M2-D). In mammalian cell lines, PHA-022121 and PHA-022484 show high affinity for the recombinant human bradykinin B receptor with K values of 0.

Small-molecule inhibitors of the PDZ domain of Dishevelled proteins interrupt Wnt signalling.

Dishevelled (Dvl) proteins are important regulators of the Wnt signalling pathway, interacting through their PDZ domains with the Wnt receptor Frizzled. Blocking the Dvl PDZ-Frizzled interaction represents a potential approach for cancer treatment, which stimulated the identification of small-molecule inhibitors, among them the anti-inflammatory drug Sulindac and Ky-02327. Aiming to develop tighter binding compounds without side effects, we investigated structure-activity relationships of sulfonamides.
