Varenicline is a synthetic chemical substance produced from the alkaloid cytisine, used for smoking treatment, which acts as a partial agonist for α4β2 and α3β4 nicotinic cholinergic receptors and as a total agonist for α7 receptor. While there are studies regarding varenicline's non-smoking-related effects, as in treatment for drug dependence, there are no studies in the literature evaluating the long-term toxicity of varenicline through a physiological approach. Thus, the aim of this study was to evaluate possible toxicity through hematological, biochemical and anatomopathological parameters of prolonged exposure (30 days) to varenicline in rats...

Glioma is the most common malignant brain tumor in adults and represents one of the most aggressive and life‑threatening types of cancer in humans. Increasing studies have revealed that microRNAs are abnormally expressed in various types of human cancer, and have oncogenic or tumor suppressive roles, which depend primarily on the type of cancer. The present study aimed to investigate the expression level and effects of microRNA‑186 (miR‑186) on glioma, and its underlying molecular mechanism. Reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) analysis was performed to detect the expression of miR‑186 in glioma tissues and cell lines...

T cell‑associated inflammation, particularly type 2 inflammation, has an important role in asthma pathogenesis, which is suppressed by regulatory T cells (Tregs). Proviral integration site for Moloney murine leukemia virus 2 (PIM2), a member off the serine/threonine kinase family, promotes the growth and survival of T cells and influences the function of Treg cells. However, whether PIM2 affects asthma pathogenesis remains unclear. Peripheral blood mononuclear cells and Treg cells from asthmatic and healthy subjects were obtained, and the expression level of PIM2 was measured by reverse transcription‑quantitative polymerase chain reaction and immunocytochemistry...

Transparent non-volatile memory devices are desirable for realizing visually-clear integrated systems for information storage. Optical transparency provides advantages in applications such as smart glass electronic devices and wearable electronics. However, achieving high transparency limits the choice of active layers as well as the electrodes; thereby, constraining device processing and performance. Here, we demonstrate bilayer transparent memory cells using room temperature deposited amorphous strontium titanate as the functional material and indium tin oxide electrodes...

Using the difference of the polarization transmission spectra of elliptical nanohole arrays (ENAs), the figure of merit (FOM) of the sensor performance of ENA can be significantly improved, and is inversely proportional to the measurement resolution. By optimizing the aspect ratio of the elliptical holes, Ag thickness, substrate-effect, and adhesive layer, the sensitivity, FOM, and relative sensitivity of the ENA can be improved to be 775 nm RIU(-1), 705 RIU(-1), and 70.23%, respectively, with an excellent linear dependence on the change of refractive index...

BACKGROUND: Hundreds of drug products are currently marketed in the United States without approval from the FDA. The 2006 Unapproved Drugs Initiative (UDI) requires manufacturers to remove these drug products from the market or obtain FDA approval by demonstrating evidence of safety and efficacy. Once the FDA acts against an unapproved drug, fewer manufacturers remain in the market, potentially enabling drug price increases and greater susceptibility to drug shortages. There is a need for systematic study of the UDI's effect on prices and shortages of all targeted drugs...

BACKGROUND: As a result of global concern about rising drug costs, many U.S. payers and European agencies such as the National Health Service have partnered with pharmaceutical companies in performance-based risk-sharing arrangements (PBRSAs) by which manufacturers share financial risk with health care purchasing entities and authorities. However, PBRSAs present many administrative and legal challenges that have minimized successful contract experiences in the United States. OBJECTIVE: To (a) identify drug and disease characteristics and contract components that contribute to successful PBRSA experiences and the primary barriers to PBRSA execution and (b) explore solutions to facilitate contract negotiation and execution...
