Bone induction by porous glass ceramic made from Bioglass (45S5).

Abstract: Porous glass ceramic, which was prepared from Bioglass® powder (45S5, U.S. Biomaterials) by foaming with diluted H2O2 solution and sintering at 1000 °C for 2 h, was implanted as cylinders (5 mm in diameter and 6 mm in length) in thigh muscles of dogs for 3 months. Histological observation was made on thin un-decalcified sections. Bone formation was histologically found in pores of all implants (X16) retrieved from 16 dogs. The bone tissue was also identified with backscattered scanning electron microscopy observation (BSE) and energy dispersive X-ray microanalysis (EDX). This is the first report of bone induction in soft tissues of animals by glass ceramic that has long been recognized as a bioactive (osteoconductive) biomaterial. The present results justify the impetus to investigate the osteoinductivity of calcium phosphate-based biomaterials, to study the mechanism of bone induction (osteoinduction) by calcium phosphate-based biomaterials, to develop osteoinductive calcium phosphate-based biomaterials, and to examine the relation between osteoinduction and osteoconduction. © 2001 John Wiley & Sons, Inc.

Co-MOF nanosheet array: A high-performance electrochemical sensor for non-enzymatic glucose detection

Abstract: It is important to construct and develop non-noble-metal nanoarray architecture for sensitive and selective detection of glucose In this paper, we testify the hydrothermal synthesis of Co-MOF nanosheet array on nickel foam from aqueous Co2+ and terephthalic acid The resulting Co-MOF array on Ni foam (Co-MOF/NF) exhibits strong activity for glucose oxidation electrocatalysis in alkaline media As a promising enzymatic-free sensing, the speedy amperometric response of

Implementation strategies for emergency medical services within stroke systems of care: a policy statement from the American Heart Association/American Stroke Association Expert Panel on Emergency Medical Services Systems and the Stroke Council.

Abstract: Stroke remains the third leading cause of death and a leading cause of long-term disability among Americans, despite advances in stroke prevention, diagnosis, treatment, and rehabilitation Approximately 700 000 individuals suffer a new or recurrent stroke each year1 Advances over the past decade in acute stroke care, including the introduction of fibrinolytic and other short-term therapies, have highlighted the critical roles of emergency medical services (EMS) agencies and emergency medical services systems (EMSS) in optimizing stroke care2–7 In this context, the term “EMS” refers to the full scope of prehospital services necessary for the acute care of patients with stroke, including 9-1-1 activation and dispatch, emergency medical response, triage and stabilization in the field, and transport by ground or air ambulance to a hospital or between facilities The term “EMSS” refers to the delivery systems for EMS that may be organized on a local, regional, statewide, or nationwide basis8 EMSS involves the organization of public and private resources for the delivery of emergency medical care These systems include the community, emergency medical and healthcare personnel, public safety agencies, emergency facilities, and critical care units The dissemination of public information and education, provision of professional training, and development of disaster planning and standardized record keeping also are key elements of EMSS Additionally, EMSS must address issues related to communication, transportation, access to care, patient transfer, mutual aid (the sharing of resources across EMSS), and system review and evaluation9 The successful integration of one (and often multiple) EMSS is critical to ensuring the effectiveness of a stroke system of care The American Stroke Association (ASA), a division of the American Heart Association (AHA), is dedicated to improving stroke prevention, treatment, and rehabilitation through research, education, advocacy, and the development of scientifically based standards and guidelines In 2004, the …

The psychological distress and coping styles in the early stages of the 2019 coronavirus disease (COVID-19) epidemic in the general mainland Chinese population: A web-based survey.

Abstract: As the epidemic outbreak of 2019 coronavirus disease (COVID-19), general population may experience psychological distress. Evidence has suggested that negative coping styles may be related to subsequent mental illness. Therefore, we investigate the general population's psychological distress and coping styles in the early stages of the COVID-19 outbreak. A cross-sectional battery of surveys was conducted from February 1-4, 2020. The Kessler 6 psychological distress scale, the simplified coping style questionnaire and a general information questionnaire were administered on-line to a convenience sample of 1599 in China. A multiple linear regression analysis was performed to identify the influence factors of psychological distress. General population's psychological distress were significant differences based on age, marriage, epidemic contact characteristics, concern with media reports, and perceived impacts of the epidemic outbreak (all p <0.001) except gender (p = 0.316). The population with younger age (F = 102.04), unmarried (t = 15.28), with history of visiting Wuhan in the past month (t = -40.86), with history of epidemics occurring in the community (t = -10.25), more concern with media reports (F = 21.84), perceived more impacts of the epidemic outbreak (changes over living situations, F = 331.71; emotional control, F = 1863.07; epidemic-related dreams, F = 1642.78) and negative coping style (t = 37.41) had higher level of psychological distress. Multivariate analysis found that marriage, epidemic contact characteristics, perceived impacts of the epidemic and coping style were the influence factors of psychological distress (all p <0.001). Epidemic of COVID-19 caused high level of psychological distress. The general mainland Chinese population with unmarried, history of visiting Wuhan in the past month, perceived more impacts of the epidemic and negative coping style had higher level of psychological distress in the early stages of COVID-19 epidemic. Psychological interventions should be implemented early, especially for those general population with such characteristics.
