Background: General anesthesia (GA) for caesarean section (CS) has distinctive characteristics that may increase the risk of awareness during GA (AGA). Objectives: The aim of this study was to investigate the incidence of unintended awareness during GA (AGA) in CS. Materials & Methods: This cross-sectional descriptive study was performed in Alzahra Hospital in Rasht City, Iran. Eligible wo...

The aim of this study was to construct redox- and pH-responsive degradable manganese dioxide (MnO2) nanosheets for cancer theranostic application. The small MnO2 nanosheets were synthesized, and then functionalized by hyaluronic acid (HA), demonstrating excellent stability and tumor-targeting ability. Cisplatin (cis-diamminedichloroplatinum [CDDP]) was absorbed by the nanosheets through a physi...

MnO2 is considered one of the most promising pseudocapactive materials for high-performance supercapacitors given its high theoretical specific capacitance, low-cost, environmental benignity, and natural abundance. However, MnO2 electrodes often suffer from poor electronic and ionic conductivities, resulting in their limited performance in power density and cycling. Here we developed a "conduct...

Nanostructured transition-metal oxides can store high-density energy in fast surface redox reactions, but their poor conductivity causes remarkable reductions in the energy storage of most pseudocapacitors at high power delivery (fast charge/discharge rates). Here it is shown that electron-correlated oxide hybrid electrodes made of nanocrystalline vanadium sesquioxide and manganese dioxide with...

In this study, alkaline solid embeddable MnO2 is used as a reference sensor for concrete environments. The performance characteristics are evaluted in a saturated calcium hydroxide solution, a synthetic concrete pore solution and ordinary Portland cement (OPC) extracts which correspond to he concrete environments. The electrochemical stability of the MnO electrode is studied in the said concret...

Oxidized carbon nanosheets (OCNs), produced from black carbon nanospheres and used as a conductive additive in the supercapacitor electrodes of MnO2 nanorods, can significantly improve the charge-storage performance of the symmetric MnO2-nanorod supercapacitors with a maximum specific energy of 64 W h kg(-1) and power of 3870 W kg(-1). An optimum material composition of the supercapacitor elect...

introduction recently topical 3% diclofenac is commonly used to treat actinic keratosis (ak). it is proposed that it may also have a potential effect on hair growth. case presentation three male patients were visited in the dermatology department and received treatment with topical 3% diclofenac gel because of scalp ak. all patients also had concomitant androgenetic alopecia (aga). during the f...

Composite electrodes of polyaniline/MnO2-Multi walled carbon nanotube (PANI/MnO2-MWCNT), MnO2-MWCNT nanocomposites and MWCNT was produced by the in situ direct coating approach. The supercapacitor performance of the nanocomposites was studied by Fourier transform infrared (FT-IR) spectroscopy and scanning electron microscopy (SEM). The electrochemical properties of electrodes were also investig...

Large-area ultrafine MnO2 nanowire arrays (NWA) directly grew on a carbon fiber (CF, used as a substrate) by a simple electrochemical method, forming three-dimensional (3D) hierarchical heterostructures of a CF@MnO2 NWA composite. As an electrode for supercapacitors, the CF@MnO2 NWA composite exhibits excellent electrochemical performances including high specific capacitance (321.3 F g-1 at 100...

Background and objective: Psoriasis is chronic inflammatory skin disorder with a wide variety of clinical presentations. Presence of anti-gliadin antibody (AGA) has been reported in 16% of psoriatic patients. This study was designed to determine the frequency of the presence of AGA in psoriatic patients. Materials and Methods: After recording the demographic data and the severity of disease acc...
