TL;DR: The results indicate cisplatin nephrotoxicity is characterized by activation of proinflammatory cytokines and chemokines and TNF-alpha appears to play a central role in the activation of this cytokine response and also in the pathogenesis of cisPlatin renal injury.
Abstract: The purpose of these studies was to examine the role of cytokines in the pathogenesis of cisplatin nephrotoxicity. Injection of mice with cisplatin (20 mg/kg) led to severe renal failure. The expression of cytokines, chemokines, and ICAM-1 in kidney was measured by ribonuclease protection assays and RT-PCR. We found significant upregulation of TNF-alpha, TGF-beta, RANTES, MIP-2, MCP-1, TCA3, IL-1beta, and ICAM-1 in kidneys from cisplatin-treated animals. In addition, serum, kidney, and urine levels of TNF-alpha measured by ELISA were increased by cisplatin. Inhibitors of TNF-alpha production (GM6001, pentoxifylline) and TNF-alpha Ab's reduced serum and kidney TNF-alpha protein levels and also blunted the cisplatin-induced increases in TNF-alpha, TGF-beta, RANTES, MIP-2, MCP-1, and IL-1beta, but not ICAM-1, mRNA. In addition, the TNF-alpha inhibitors also ameliorated cisplatin-induced renal dysfunction and reduced cisplatin-induced structural damage. Likewise, TNF-alpha-deficient mice were resistant to cisplatin nephrotoxicity. These results indicate cisplatin nephrotoxicity is characterized by activation of proinflammatory cytokines and chemokines. TNF-alpha appears to play a central role in the activation of this cytokine response and also in the pathogenesis of cisplatin renal injury.

TL;DR: A range of effective cognitive behavioural and pharmacological treatments for children and adults now exists; the challenges lie in optimum integration and dissemination of these treatments, and learning how to help the 30-40% of patients for whom treatment does not work as discussed by the authors.

TL;DR: Findings indicate that epithelial differentiation and tumor cell viability are associated, and that EMT regulators in "K-Ras-addicted" cancers represent candidate therapeutic targets.

TL;DR: The results presented here provide a molecular basis for the Abeta-induced cognitive deficits and, moreover, show that rapamycin, an FDA approved drug, improves learning and memory and reduces Abeta and Tau pathology.

TL;DR: Data indicate that the reinjection of thallium improves the detection of ischemic myocardium and that myocardial regions with improvedThallium uptake on reinjection imaging represent viable but jeopardized myocardia.
Abstract: Background. The identification of ischemic but viable myocardium by thallium exercise scintigraphy is often imprecise, since many of the perfusion defects that develop in ischemic myocardium during exercise do not "fill in" on subsequent redistribution images. We hypothesized that a second injection of thallium given after the redistribution images were taken might improve the detection of ischemic but viable myocardium. Methods. We studied 100 patients with coronary artery disease, using thallium exercise tomographic imaging and radionuclide angiography. Patients received 2 mCi of thallium intravenously during exercise, redistribution imaging was performed three to four hours later, and a second dose of 1 mCi of thallium was injected at rest immediately thereafter. The three sets of images (stress, redistribution, and reinjection) were then analyzed. Results. Ninety-two of the 100 patients had exercise-induced perfusion defects. Of the 260 abnormal myocardial regions identified by stress imaging...
