Characterization of the MgO/GaSe0.5S0.5 heterojunction designed for visible light communications
In this study an optoelectronic design is reported and characterized. The device is made of p-type MgO solved in sodium silicate binder and n-type GaSe0.5S0.5 heterojunction. It is described by means of X-ray diffraction, optical absorption and reflection in the incident light wavelength range of 190–1100nm and by means of dark and 406nm laser excited current (I)–voltage (V) characteristics. The optical reflectance was also measured as a function of angle of incidence of light in the range of 35–80°. The structural analysis revealed no change in the existing phases of the device composers. In addition, it was observ...

List-Kratochvil We investigate the structural, electrical and optical properties of transparent electrodes, consisting of Al-doped ZnO (AZO) and ultrathin Au layers, sputtered on polyethylene terephthalate (PET). These electrodes are relevant for optoelectronic devices and thin film photovoltaics. When deposited on AZO, Au films as thin as 3nm form electrically conductive, meandering structures, whereas uniform Au films are obtai...

Adherence to analgesics for cancer pain: A comparative study of African Americans and Whites using an electronic monitoring device
Despite well-documented disparities in cancer pain outcomes among African Americans, surprisingly little research exists on adherence to analgesia for cancer pain in this group. We compared analgesic adherence for cancer-related pain over a 3-month period between African Americans and Whites using Medication Event Monitoring System [MEMS]. Patients (n=207) were recruited from outpatient medical oncology clinics of an academic medical center in Philadelphia [>18 years of age, diagnosed with solid tumors or multiple myeloma, with cancer-related pain, and at least one prescription of oral around-the-clock analgesic (ATC)]. (S...

Long Term Outcome of The Management of Chronic Neuropathic Pain – A Prospective Observational Study
This prospective observational cohort study addressed the long term clinical effectiveness of the management of chronic neuropathic non-cancer pain at seven Canadian tertiary pain centres. Patients were treated according to standard guidelines and followed at 3, 6, 12, 18 and 24 months. Standard outcome measures for pain, mood, quality of life and overall treatment satisfaction were administered with the primary outcome measure designated as the composite of 30% reduction in average pain intensity and one point drop in the mean Interference Scale Score (0-10) of the Brief Pain Inventory at 12 months relative to baseline.

Preparation and characterization of electrosprayed daidzein–loaded PHBV microspheres
In this study, daidzein–loaded poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) microspheres were prepared using electrospraying. The obtained microspheres had uniform surface morphology, and narrow particle size distribution with mean particle size of 4.8μm. Daidzein was determined to be in amorphous state in the PHBV microspheres by differential scanning calorimetry analysis. Encapsulated daidzein was released with a low initial burst release (7.6% at 1h) followed by a sustained release over a period of ~3 days. The developed PHBV microspheres with daidzein delivery function have potential applications in the treat...

Symptoms of depression are associated with opioid use regardless of pain severity and physical functioning among treatment-seeking chronic pain patients
This study investigated the association between opioid use, pain, and depression in patients evaluated at a university-based outpatient pain clinic. Of the 2,104 new patients included, 55.89% reported current opioid use and demonstrated a worse phenotypic profile (e.g. higher pain severity, worse physical functioning) compared to non-opioid users. Additionally, more opioid users reported symptoms suggestive of depression than those not taking opioids (43.6% vs. (Source: The Journal of Pain)

Carbon nanotubes enhance intercalated disc assembly in cardiac myocytes via the β1-integrin-mediated signaling pathway.
Abstract Carbon nanotubes (CNTs) offer a new paradigm for constructing functional cardiac patches and repairing myocardial infarction (MI). However, little is known about how CNTs enhance the mechanical integrity and electrophysiological function of cardiac myocytes. To address this issue, we investigated the regularity and precise mechanism of the influence of CNTs on the assembly of intercalated disc (IDs). Here, single walled CNTs incorporated into collagen substrates were utilized as growth supports for neonatal cardiomyocytes, which enhanced cardiomyocyte adhesion and maturation. Furthermore, through the use o...

Does the adhesive strategy influence the post-operative sensitivity in adult patients with posterior resin composite restorations?
The demand for esthetic restorations, the increased fear of amalgam toxicity [1,2] and the environmental problems [3,4] associated with mercury have increasingly led universities to teach resin composite for restorations of posterior cavities in many countries [5–8]. (Source: Dental Materials)

The Lateral Prefrontal Cortex Mediates the Hyperalgesic Effects of Negative Cognitions in Chronic Pain Patients
Although high levels of negative affect and cognitions have been associated with greater pain sensitivity in chronic pain conditions, the neural mechanisms mediating the hyperalgesic effect of psychological factors in patients with pain disorders are largely unknown. In this cross-sectional study, we hypothesized that 1) catastrophizing modulates brain responses to pain anticipation and 2) anticipatory brain activity mediates the hyperalgesic effect of different levels of catastrophizing in fibromyalgia (FM) patients.

Functional liposomes in the cancer-targeted drug delivery
Cancer is considered as one of the most severe health problems and is currently the third most common cause of death in the world after heart and infectious diseases. Novel therapies are constantly being discovered, developed and trialed. Many of the current anticancer agents exhibit non-ideal pharmaceutical and pharmacological properties and are distributed non-specifically throughout the body. This results in death of the both normal healthy and malignant cells and substantially leads to accruing a variety of serious toxic side effects. Therefore, the efficient systemic therapy of cancer is almost impossible due to harmf...
