Mechanisms of Nanoglass Ultrastability.

Added: 2016-02-10 07:00:00

The origin of the astonishing properties of recently discovered ultrastable nanoglasses is presently not well understood. Nanoglasses appear to exhibit density variations not common in bulk glasses and differ significantly in thermal, magnetic, biocompatible and mechanic properties from the bulk materials of the same composition. Here, we investigate a generic model system that permits modeling of...

This study demonstrates the feasibility of using quantitative real time PCR to measure genomic bacterial load in the nasopharynx of children with invasive meningococcal disease and shows that these loads are exceptionally high (median 6.6 x 10 (Range 1.2 x 10 to 1.1 x 10) genome copies of Neisseria meningitidis per swab).

After symptomatic human parechovirus (HPeV) infection in infants, the duration of (mostly asymptomatic) shedding in feces was 2-24 weeks (median 58 days). HPeV Ct-value could neither differentiate between symptomatic disease and asymptomatic shedding nor between severe and mild disease as high Ct-values (indicating low viral loads) were observed in HPeV3-infected children with severe disease.

Cytomegalovirus (CMV) causes significant morbidity and mortality in congenitally-infected children and immunocompromised hosts. Among healthy individuals, CMV is generally thought to cause mild, self-limited illness. CMV enterocolitis, in particular, is rarely considered among immunocompetent children presenting with diarrhea. We describe two cases of invasive CMV colitis in immunocompetent infant...

Isoniazid exposure causes dose-dependent pyridoxine deficiency. Recently, the recommended dosage of isoniazid in children was increased from 5(4-6) to 10(10-15) mg/kg/day. We aimed to analyze longitudinally pyridoxine levels in a cohort of previously healthy children and adolescents treated with isoniazid. Mild symptom-free pyridoxine deficiency was observed in 4/75(5.6%) and 3/40(7.5%) at baselin...

The effects of propylene carbonate (PC) content in CsPF6-containing electrolytes on the performances of graphite electrode in lithium half cells and in graphite||LiNi0.80Co0.15Al0.05O2 (NCA) full cells are investigated. It is found that the performance of graphite electrode is significantly affected by PC content in the CsPF6-containing electrolytes. An optimal PC content of 20% by weight in the s...

Several studies have found improved glycemic control with continuous subcutaneous insulin infusion compared with multiple daily insulin injections for patients with type 1 diabetes, albeit for a relatively short-period of follow-up. This prospective study presents for the first time the optimization of glycemic control with insulin pumps in a cohort of Greek patients with type 1 diabetes for a 3-y...

Wearable accelerometers can be used to objectively assess physical activity. However, the accuracy of this assessment depends on the underlying method used to process the time series data obtained from accelerometers. Several methods have been proposed that use this data to identify the type of physical activity and estimate its energy cost. Most of the newer methods employ some machine learning t...

The degenerate rearrangement in the 21-homododecahedryl cation (1) has been studied via density functional theory computations and Born-Oppenheimer Molecular Dynamics simulations. Compound 1 can be described as a highly fluxional hyperconjugated carbocation. Complete scrambling of 1 can be achieved by the combination of two unveiled barrierless processes. The first one is a "rotation" of one of th...

The magnetic properties of a nanoscale system are inextricably linked to its local environment. In ad-atoms on surfaces and inorganic layered structures the exchange interactions result from the relative lattice positions, layer thicknesses and other environmental parameters. Here, we report on a sample-dependent sign inversion of the magnetic exchange coupling between the three unpaired spins of ...

Early discussions about advance care planning (ACP) have been associated with improved patient and caregiver outcomes for patients with serious illness. Many patients with heart failure (HF) may benefit from more timely ACP, in part due to the unpredictable trajectory of the disease.

Immunohistochemistry has helped to make surgical pathology the "gold" standard for tumor diagnosis. However, given the numerous problems associated with the use of antibodies for the staining of cellular markers in paraffin-embedded tissues, there is a requirement for novel agents that have the advantages of antibodies, but with few of the disadvantages. Aptamers, which are chemical antibodies, ar...

The self-assembly of structures with 'addressable complexity' - where every component is distinct and is programmed to occupy a specific location within a target structure - is a promising route to engineer- ing materials with precisely defined morphologies. Because systems with many components are inherently complicated, one might assume that the chances of successful self-assembly are extraordin...

This study explored RN-BSN students' perceptions of practice differences between nurses prepared with an ADN and BSN. Five themes were identified in 20 students' discussion posts: "a nurse is a nurse" at the bedside, beyond the bedside, BSN wanted, digging deeper, and appraisal. Results illustrate the need for educators to assist nurses in translating the differentiated educational competencies to...

Multisite education research projects have many benefits as well as perceived barriers. In this article, we share our experiences with a multisite education research project and the barriers we overcame to reap the benefits. The outcome of our research resulted in increased rigor, role-modeling professional collaboration, and promotion of future multisite education studies. The strategies presente...

The need for clinicians trained in palliative care will increase as more Americans live with life-limiting illness. Although multiple studies have described the nature of palliative care education in prelicensure programs, there have been no similar studies of nurse practitioner programs. We surveyed 101 nurse practitioner programs. Most programs provide little instruction in palliative care; educ...

Glyphosate [N-(phosphonomethyl)glycine] has been described as the ideal herbicide because of its unique properties. There is some conflicting information concerning the structures and conformations involved in the protonation process of glyphosate. Protonation may influence the chemical and physical properties of glyphosate, modifying its structure and the chemical processes in which it is involve...

To evaluate bone healing after osteotomy by surgical drill (D) and piezoelectric ultrasound (U), Wistar rats were submitted to femoral osteotomy and submitted to histological analysis. After 60 h, slight (83.3%) and moderate (3.4%) inflammatory areas were frequent in the U defects whereas D group presented moderate (33.3%) and severe (16.6%) inflammatory infiltrate (P

The aim of the present study was to compare the efficacy of Nd:YAG laser and K3 rotary system in the non-surgical root canal retreatment.

Numerous studies have been published about the prosthetic rehabilitation of the postoncological maxillo-facial patient, but the guidelines that emerge lack a correlation between the anatomical classification of the treated site, which generally is preparatory upon surgery, and the type of prosthetic rehabilitation appropriate to the new anatomical and functional condition. With this correlation, i...

In the current study, the utility of lymph node ratio (LNR) was evaluated as an alternative method for predicting locoregional failure in patients with advanced head and neck cancer.

Myeloablative and hematopoietic stem cells transplantation therapy (HSCT) often acts as side-effect to oral mucositis (OM) with no effective treatment. This randomized-controlled trial analyzed the efficacy of palifermin, administered as a dose during HSCT therapy, as primary prophylaxis on pediatric patients with acute lymphoblastic leukemia (ALL).
