UNLABELLED RNA interference (RNAi) is a potent and specific mechanism for regulating gene expression. Harnessing RNAi to silence genes involved in disease holds promise for the development of a new class of therapeutics. Delivery is key to realizing the potential of RNAi, and lipid nanoparticles (LNP) have proved effective in delivery of siRNAs to the liver(More)
Vulnerability to cavitation is a key variable defining the limits to drought resistance in woody plants (Kursar et al., 2009). This trait is typically assessed by a vulnerability curve, which can be generated by a range of methods, including dehydration (Sperry et al., 1988), air injection (Cochard et al., 1992), and centrifugation (Alder et al., 1997).(More)
Protein kinases play a crucial role in the intracellular signaling pathways involved in inflammation and cell proliferation. Advances in our understanding of these metabolic pathways and of the role played by intracellular signaling in the pathogenesis of psoriasis have led to research in this area and the development of a new class of drugs for the(More)
Clinical experience increasingly suggests that molecular prescreening and biomarker enrichment strategies in phase I trials with targeted therapies will improve the outcomes of patients with cancer. In keeping with the exigencies of a personalized oncology program, tumors from patients with advanced chemorefractory colorectal cancer were analyzed for(More)
Chronic renal failure patients are prone to soft tissue calcifications. A phenomenon of acute ischemic skin necrosis and dermohypodermic arteriolar medial calcification has been described recently in patients with chronic renal failure and secondary hyperparathyroidism (HPT). This phenomenon, termed calciphylaxis, occurs in response to certain factors, the(More)
Many human tumors of epithelial origin contain cells overexpressing the epidermal growth factor (EGF) receptor, and there is convincing evidence that cancer cell growth is correlated with the loss of the normal regulation of the EGF receptor signal transduction pathway. Some cancers are clearly dependent on activation of the EGF receptor for their(More)
PURPOSE Previous studies have highlighted the importance of an appropriate human epidermal growth factor receptor 2 (HER2) evaluation for the proper identification of patients eligible for treatment with anti-HER2 targeted therapies. Today, the relationship remains unclear between the level of HER2 amplification and the outcome of HER2-positive gastric(More)
Increased levels of epidermal growth factor receptor (EGFR) have been shown on squamous cell carcinomas. Recently, we described a squamous cell carcinoma (MH-85) derived from the oral cavity which was associated with several paraneoplastic syndromes including hypercalcemia and cachexia. This tumor induced the same paraneoplastic syndromes in nude mice(More)
BACKGROUND There are few data on the prevalence of obesity in the general psoriasis population and on the real impact of obesity on the management of psoriasis patients in the clinical setting. OBJECTIVES To evaluate the prevalence of overweight and obesity in patients with moderate-to-severe psoriasis compared to the general population and to assess the(More)
Psoriasis, a chronic multifactorial inflammatory disease that develops in genetically predisposed individuals, affects approximately 1.5% of the Spanish population. This disease has a negative impact on patients' quality of life, and long-term therapy is often required to control the symptoms. In addition to the classical systemic treatments (methotrexate,(More)
