The effect of hand fine motor skills on peritoneal dialysis-related peritonitis.

Introduction: We aimed to evaluate the relationship between the hand fine motor skills of peritoneal dialysis (PD) practitioners and PD-related peritonitis.

Methods: This multicenter prospective observational study was conducted with 120 incident PD patients. Patients were divided into two groups who had PD-related peritonitis within the first year as Group 1, and those who did not as Group 2.

Faradaic effects in electrochemically gated graphene sensors in the presence of redox active molecules.

Field-effect transistors (FETs) based on graphene are promising devices for the direct sensing of a range of analytes in solution. We show here that the presence of redox active molecules in the analyte solution leads to the occurrence of heterogeneous electron transfer with graphene generating a Faradaic current (electron transfer) in a FET configuration resulting in shifts of the Dirac point. Such a shift occurs if the Faradaic current is significantly high, e.

Binding Kinetics of Methylene Blue on Monolayer Graphene Investigated by Multiparameter Surface Plasmon Resonance.

In this paper, we study the interaction of a small dye molecule, namely, methylene blue (MB) with graphene surfaces using surface plasmon resonance (SPR). We show that by utilizing all of the parameters of the SPR angular dip and exploiting the fact that MB absorbs light at the operating wavelength, it is possible to detect the binding of small molecules that would otherwise not give a significant signal. The binding of MB to unmodified graphene is found to be stronger than that for gold.

Synthesis and organic solar cell performance of BODIPY and coumarin functionalized SWCNTs or graphene oxide nanomaterials.

The synthesis and characterization of new hybrid materials based on reduced graphene oxide (rGO) or single walled carbon nanotubes (SWCNTs) covalently functionalized by 4,4'-difluoro-8-(4-propynyloxy)-phenyl-1,3,5,7-tetramethyl-4-bora-3a,4a-diaza-s-indacene (BODIPY) (2) or 7-(prop-2-yn-1-yloxy)-3-(3',4',5'-trimethoxyphenyl)-coumarin (4) as light harvesting groups have been described. The organic solar cell performances of these novel nanomaterials in P3HT:PCBM blends were investigated. These covalently bonded hybrid materials (reduced graphene oxide:BODIPY (GB), reduced graphene oxide:Coumarin (GC), SWCNTs:BODIPY (CB) and SWCNTs:Coumarin (CC)) were prepared by an azide-alkyne Huisgen cycloaddition (click) reaction between the azide bearing SWCNTs or rGO and terminal ethynyl functionalized BODIPY (2) or coumarin (4) derivatives.

Discrimination of urinary tract infection pathogens by means of their growth profiles using surface enhanced Raman scattering.

Urinary tract infection (UTI) is a widespread infection and affects millions of people around the globe. The gold standard for identification of microorganisms causing infection is urine culture. However, current methods require at least 24 h for the results.

The dissection of reinforced endotracheal tube internal wall causing intraoperative airway obstruction under general anesthesia. Case report.

Endotracheal intubation is performed to establish a secure airway. However, this carries its risks and obstruction of an endotracheal tube (ETT) is a potentially life-threatening event. We report two cases with an obstruction of the resterilized, single use, spiral, reinforced endotracheal tubes by dissection of the internal wall.

Lifestyle behaviors and early diagnosis practices of cancer patients.

Background: The aim was to determine the lifestyle behaviors and the practices for early diagnosis of cancer of cancer patients.

Materials And Methods: A descriptive cross-sectional design was used for this study. The sample consisted of 222 patients with a diagnosis of cancer (non-random sample method).

Intraoperative infusion of dexmedetomidine reduces perioperative analgesic requirements.

Purpose: This prospective, randomized, double-blind study was designed to assess whether intraoperative infusion of dexmedetomidine provides effective postoperative analgesia. Postoperative pain scores and morphine consumption were compared in a treated group and a placebo group, both of which received patient-controlled morphine after total abdominal hysterectomy.

Methods: Fifty women were randomly assigned to two groups.

Epidural neostigmine produces analgesia but also sedation in women after cesarean delivery.

Background: Intrathecal neostigmine produces analgesia but also nausea, limiting its utility. In contrast, epidural administration of neostigmine has been suggested to produce postoperative analgesia without nausea in nonpregnant patients. The purpose of this study was to examine the dose range for efficacy and side effects of epidural neostigmine in women at cesarean delivery receiving combined spinal-epidural anesthesia.
