Synthesis and Characterization of Rebondable Polyurethane Adhesives Relying on Thermo-Activated Transcarbamoylation.

Dynamic polymer networks combine the noteworthy (thermo)mechanical features of thermosets with the processability of thermoplastics. They rely on externally triggered bond exchange reactions, which induce topological rearrangements and, at a sufficiently high rate, a macroscopic reflow of the polymer network. Due to this controlled change in viscosity, dynamic polymers are repairable, malleable, and reprocessable.

Development of a Screening Platform for Optimizing Chemical Nanosensor Materials.

Chemical sensors, relying on changes in the electrical conductance of a gas-sensitive material due to the surrounding gas, typically react with multiple target gases and the resulting response is not specific for a certain analyte species. The purpose of this study was the development of a multi-sensor platform for systematic screening of gas-sensitive nanomaterials. We have developed a specific Si-based platform chip, which integrates a total of 16 sensor structures.

Adjusting surface coverage of Pt nanocatalyst decoration for selectivity control in CMOS-integrated SnO thin film gas sensors.

Smart gas-sensor devices are of crucial importance for emerging consumer electronics and Internet-of-Things (IoT) applications, in particular for indoor and outdoor air quality monitoring (, CO levels) or for detecting pollutants harmful for human health. Chemoresistive nanosensors based on metal-oxide semiconductors are among the most promising technologies due to their high sensitivity and suitability for scalable low-cost fabrication of miniaturised devices. However, poor selectivity between different target analytes restrains this technology from broader applicability.

Microscopy-based high-throughput assays enable multi-parametric analysis to assess adverse effects of nanomaterials in various cell lines.

Manufactured nanomaterials (MNMs) selected from a library of over 120 different MNMs with varied compositions, sizes, and surface coatings were tested by four different laboratories for toxicity by high-throughput/-content (HT/C) techniques. The selected particles comprise 14 MNMs composed of CeO, Ag, TiO, ZnO and SiO with different coatings and surface characteristics at varying concentrations. The MNMs were tested in different mammalian cell lines at concentrations between 0.

Rapid Prototyping of a High Sensitivity Graphene Based Glucose Sensor Strip.

A rapid prototyping of an inexpensive, disposable graphene and copper nanocomposite sensor strip using polymeric flexible substrate for highly sensitive and selective nonenzymatic glucose detection has been developed and tested for direct oxidization of glucose. The CuNPs were electrochemically deposited on to the graphene sheets to improve electron transfer rates and to enhance electrocatalytic activity toward glucose. The graphene based electrode with CuNPs demonstrated a high degree of sensitivity (1101.

Impact of an interprofessional oral health education program on health care professional and practice behaviors: a RE-AIM analysis.

Background: Early childhood caries is the most common chronic childhood condition and largely preventable. Access to oral health preventive services (OHPS) for children at risk for caries is suboptimal and could be expanded if they were provided by non-dental professionals. Many state Medicaid programs in the USA now reimburse non-dental professionals for OHPS but require that they receive oral health education (OHE) to be reimbursed.

Endocytosis of Fgf8 is a double-stage process and regulates spreading and signaling.

Tightly controlled concentration gradients of morphogens provide positional information and thus regulate tissue differentiation and morphogenesis in multicellular organisms. However, how such morphogenetic fields are formed and maintained remains debated. Here we show that fibroblast growth factor 8 (Fgf8) morphogen gradients in zebrafish embryos are established and maintained by two essential mechanisms.

Clinical support for the off-shift nurse and the graduate nurse: the clinical rock stars.

Turnover of medical-surgical nurses can be distressing and costly Establishment of the clinical resource specialist role can provide a valuable resource to off-shift RNs and have a positive impact on job satisfaction.

Long-term benefit of radon spa therapy in the rehabilitation of rheumatoid arthritis: a randomised, double-blinded trial.

This study investigates the effects of radon (plus CO2) baths on RA in contrast to artificial CO2 baths in RA rehabilitation using a double-blinded trial enrolling 134 randomised patients of an in-patient rehabilitative programme (further 73 consecutive non-randomised patients are not reported here). The outcomes were limitations in occupational context/daily living (main outcome), pain, medication and further quantities. These were measured before the start, after the end of treatment and quarterly in the year thereafter.

Prognostic value of the labour admission test and its effectiveness compared with auscultation only: a systematic review.

Objective: To assess the effectiveness of the labour admission test in preventing adverse outcomes, compared with auscultation only, and to assess the test's prognostic value in predicting adverse outcomes.

Design: Systematic review.

Setting: Labour wards in hospitals.

Long-term efficacy of radon spa therapy in rheumatoid arthritis--a randomized, sham-controlled study and follow-up.

Objective: To quantify the efficacy of a series of baths containing natural radon and carbon dioxide (1.3 kBq/l, 1.6 g carbon dioxide/l on average) versus artificial carbon dioxide baths alone in patients with rheumatoid arthritis.

Profiles of four women. Health and human rights activists.

This article briefly profiles four women physicians working for health and human rights around the world. Dr. Ruchama Marton, an Israeli psychiatrist and activist for peace in the Middle East, is a founder of Physicians for Human Rights/Israel.

Health Care Linkage Project: improving access to care.

The primary objective of the Health Care Linkage Project, funded by a grant from the Chicago Community Trust, is to develop, implement, and evaluate a primary health care linkage network within the city of Chicago that creates formalized linkages between community health centers, the Chicago Department of Health clinics, and hospitals. Six linkage networks are currently operational, with an additional two sites phased in during 1991. The success of the pilot project has been demonstrated by hundreds of patients receiving primary care and ancillary services on a more timely basis, by greater coordination between the public and private sector, by cost-savings to both patients and providers through reducing inappropriate use of services, and by a variety of spin-off projects which have improved the quality and accessibility of services.

Ultrastructure of lipoma.

Eleven benign lipogenic tumors comprising ten ordinary lipomas and one fibroblastic lipoma were studied by light and electron microscopy. The former, which contained only a few inconspicuous septa, were composed of univacuolar mature adipocytes. No young forms of adipocytic differentiation were seen reflecting the slow growth of the ordinary lipomas.

Ultrastructural "fingerprint" in cryoprecipitate and glomerular deposits: a case report of systemic lupus erythematosus.

A 20 year old woman had lupus nephritis and cryoglobulinemia. The cryoglobulins isolated from the serum and a renal biopsy specimen were studied by means of immunofluorescence, immunochemistry, and electron microscopy. Ultrastructural "fingerprint" structures were observed both in the cryoprecipitate and in the glomerular deposits, as were IgG, IgM, and IgA.

Immunofluorescence of renal lesions in paraffin-embedded and fresh-frozen sections.

Immunofluorescent findings in formalin-fixed and paraffin-embedded sections of kidneys involved by various nephropathies compared favorably with those in fresh-frozen sections. In some cases, the findings in paraffin-embedded sections were complementary. Immunoreactivity with complement could not be demonstrated.

Syphilitic lymphadenitis: immunofluorescent identification of spirochetes from imprints.

We are reporting two cases of early syphilis with inguinal buboes which were surgically excised. Th clinical impression was lymphoma in one case and inguinal hernia in the other. The correct and specific diagnosis was quickly established by the application of fluorescent antibody technique to imprints of the enlarged lymph node.

Immunological observations following vasectomy.

Lymphocytotoxic antibodies (LCA) against panels of normal lymphocytes and leukemic B-cells were demonstrated in vasectomized men. Since vasectomy is known to induce antibody formation to spermatozoa, the demonstration of these lymphocytotoxic antibodies may be related to antigenic constituents of spermatozoa such as HLA or B-cell alloantigens. Long term follow-up is needed to clarify the clinical significance of these antibodies.

Immunoblastic sarcoma following Waldenström's macroglobulinemia.

Immunoblastic sarcoma has been observed in association with, or subsequent to, chronic immune stimulation, connective tissue disorders, and immunoblastic lymphadenopathy. A case of Waldenström's macroglobulinemia progressinng after a few years into immunoblastic sarcoma is reported. Splenectomy led to disappearance of hemolytic anemia and of pulmonary infiltrates, as well as to marked reduction of macroglobulins.

Spondylothoracic dysostosis: report of two cases and review of the literature.

Two Puerto Rican infants, offsprings of nonconsanguineous parents, died with spondylothoracic dysostosis as characterized by widespread anomalies of the spine (malformed vertebral bodies including hemivertebrae), deformity of the thorax, and fan-like configuration of the ribs. The disease was lethal in early life in the 18 cases previously reported. An autosomal-recessive inheritance has been described.

Brunnian adenoma (inverted papilloma) of the urinary bladder: report of a case.

An additional case of a benign polypoid tumor of the urinary bladder is reported, the first one observed at autopsy and the first in which photographic documentation of the gross appearance is presented. The lesion was first described as an adenomatoid polyp in 1927. We consider the subsequent (1963) designation of inverted papilloma misleading.

Enterovenous fistulization in Crohn's disease.

A case of Crohn's disease was complicated by enterovenous fistulization (ileum to superior mesenteric vein) with septic manifestations. The fistulization was diagnosed by the observation of gas in the liver and by the opacification of mesenteric veins following a barium meal.
