Aims: Cardiac resynchronization therapy (CRT) reduces the incidence of sudden cardiac death and the use of appropriate implantable cardioverter-defibrillator (ICD) therapies (AICDTs); however, this antiarrhythmic effect is only observed in certain groups of patients. To gain insight into the effects of CRT on ventricular arrhythmia (VA) burden, we compared the incidence of AICDT use in four groups of patients: patients with ischaemic cardiomyopathy vs. non-ischaemic dilated cardiomyopathy (NIDC) and patients implanted with an ICD vs...

Targeted expression of gene technique is an important therapeutic strategy for lung cancer. MicroRNA-7 has been well documented as a promising tumor suppressor but never been test in specific gene-promoter-targeted expression in cancer gene therapy. Here, we first evaluated the efficacy of miR-7 expression operated by the promoter of TTF-1, a lineage-specific oncogene in lung cancer, in vitro using an eukaryotic vector of TTF-1-promoter-operated expression of miR-7 (termed as p-T-miR-7). Interestingly, using a nude mice model, the growth and metastasis of human lung cancer cells in vivo were significantly reduced in remote hypodermic injection of the p-T-miR-7 group, accompanied by increased expression of miR-7 and reduced transduction of the Akt and Erk pathway in situ...

Active ulcerative colitis is associated with significant morbidity and impairment to quality of life. Adalimumab is a welcome addition to the therapeutic armamentarium for clinicians treating patients with moderate-severe ulcerative colitis refractory to conventional therapies, an indication with few prior treatment options. It offers the convenience of self-injection and is most appropriate for outpatients with moderate disease activity. Areas covered: This review briefly summarizes data from well-designed clinical trials and observational real-life studies that demonstrate the safety and efficacy of adalimumab in UC...

Near-infrared (NIR) light-responsive hydrogels are important for biomedical applications such as remotely controlled release, but the NIR agents previously used have been largely limited to heavy-metal inorganic materials such as gold nanoparticles. In this article, we report a new type of NIR photothermal responsive hydrogels, which could undergo structural changes in response to NIR light for biomedical applications in drug delivery and controlled release. The hydrogels synthesized by integrating a narrow bandgap semiconductor polymer poly(diketopyrrolopyrrole-alt-3,4-ethylenedioxythiophene) (PDPPEDOT) with polymerization of N-isopropylacrylamide (NIPAM) show rapid and reversible mechanical shrinkage upon NIR light irradiation and can serve as carriers for anticancer drug loading and spatial/temporal control of drug release...

Compared to traditional hyperthermia methods, gold nanoparticles (Au NPs) successfully achieve site-specific incremental temperature in deep tissues. By virtue of near-infrared (NIR) laser-mediated photothermal treatment, Au NPs have been widely explored in clinical and preclinical applications, including cancer therapy and tissue engineering. In this issue of ACS Nano, Suzuki, Ciofani, and colleagues demonstrate how gold nanoshells can remotely activate striated muscle cells via inducing myotube contraction and modulating related gene expression by mild heat stimulation under NIR irradiation...

The treatment of congestive heart failure is an expensive undertaking with much of this cost occurring as a result of hospitalization. It is not surprising that many remote monitoring strategies have been developed to help patients maintain clinical stability by avoiding congestion. Most of these have failed. It seems very unlikely that these failures were the result of any one underlying false assumption but rather from the fact that heart failure is a progressive, deadly disease and that human behavior is hard to modify...

BACKGROUND AND AIM: The increasing number of coronary artery bypass grafting (CABG) is associated with a need for active introduction of methods improving immediate and long-term results of these interventions. Results of a number of studies conducted during recent years allow to consider high dose statin therapy one of such methods. In this article we present results of rosuvastatin administration to patients with ischemic heart disease (IHD) prior to surgery. METHODS: Rosuvastatin (40 mg/day) was given for 4 weeks before CABG to patients who had previously taken simvastatin (20 mg/day)...

Management of glioblastoma multiforme remains a challenging problem despite recent advances in targeted therapies. Timely assessment of therapeutic agents is hindered by the lack of standard quantitative imaging protocols for determining targeted response. Clinical response assessment for brain tumors is determined by volumetric changes assessed at 10 weeks post-treatment initiation. Further, current clinical criteria fail to use advanced quantitative imaging approaches, such as diffusion and perfusion magnetic resonance imaging...
