Peri-implantitis is a severe inflammatory pathology that affects soit and hard tissues surrounding dental implants. Nowadays, only prevention is effective to contrast peri-implantitis, but, in recent years, there is the clinical evidence of the efficiency of a therapy based on the application of radio frequency electric current, reporting that 81% of the cases (66 implants, 46 patients) were successfully treated. The aim of this paper is to present the therapy mechanism, exploring the distribution of the electric currents in normal and pathologic tissues...

Recent innovations in sensing and Information and Communication Technology (ICT) have enabled researchers in animal behavior to collect an enormous amount of data. Consequently, the development of an automated system to substitute for some of the observations and analyses that are performed currently by expert researchers is becoming a crucial issue so that the vast amount of accumulated data can be processed efficiently. For this purpose, we introduce a process for the automated classification of the social interactive status of two mice in a square field on the basis of a Hidden Markov model (HMM)...

3D printing technology has revolutionized and gradually transformed manufacturing across a broad spectrum of industries, including healthcare. Nowhere is this more apparent than in orthopaedics with many surgeons already incorporating aspects of 3D modelling and virtual procedures into their routine clinical practice. As a more extreme application, patient-specific 3D printed titanium truss cages represent a novel approach for managing the challenge of segmental bone defects. This review illustrates the potential indications of this innovative technique using 3D printed titanium truss cages in conjunction with the Masquelet technique...

The human pathogen Clostridium difficile infection (CDI) is one of the most important healthcare-associated infections. The Wood-Ljungdahl pathway, which is responsible for Acetyl-CoA biosynthesis, is essential for the survival of the pathogen and is absent in humans. The key proteins and enzymes involved in the pathway are attractive targets for the treatment of CDI. Corrinoid iron-sulfur protein (CoFeSP) is a key protein and acts as a methyl transformer in the Wood-Ljungdahl pathway. In this study, CoFeSP from Clostridium difficile (CoFeSPCd) was cloned, expressed in E...

Equivalences of two classes of dynamic models for weakly stationary multivariate time series are discussed: dynamic factor models and autoregressive models. It is shown that exploratory dynamic factor models can be rotated, yielding an infinite set of equivalent solutions for any observed series. It also is shown that dynamic factor models with lagged factor loadings are not equivalent to the currently popular state-space models, and that restriction of attention to the latter type of models may yield invalid results...

The design of innovative combustion processes relies on a comprehensive understanding of biodiesel oxidation kinetics. The present study aims at unraveling the reaction mechanism involved in the epoxidation of a realistic biodiesel surrogate, methyl trans-3-hexenoate, by hydroperoxy radicals using a bottom-up theoretical kinetics methodology. The obtained rate constants are in good agreement with experimental data for alkenes epoxidation by HO2. The impact of temperature and pressure on epoxidation pathways involving H-bonded and non H-bonded conformers was assessed...

The Magnet Recognition Program for healthcare organizations promotes excellence in nursing services and professional practices. However, organizational and community characteristics that contribute to the adoption of Magnet status remain unexplained. Investigating organizational and community factors will help determine systematic structural and contextual dimensions of Magnet hospitals previously shown to be more cost-effective in comparison with non-Magnet hospitals. Using the baseline 2005 database of all Magnet hospitals in the United States, the authors selected a matched sample to determine key organizational and community characteristics associated with Magnet adoption while controlling for regional and local factors...

BACKGROUND: An existing model for fourth-degree laceration repair uses beef tongue with plastic or vinyl tubing. This modified model substitutes beef tripe for the anal mucosa and chicken leg muscles for the anal sphincter muscle analogs to create a realistic model. METHOD: Tripe is tunneled through the body of the trimmed beef tongue and sutured like an ostomy to simulate the anal canal. The tongue is incised toward the tripe "anal canal." Chicken leg muscles are tunneled from the incision out to the cut edges of the beef tongue to create anal sphincter muscle analogs...

BACKGROUND: Since the early 90s, patient navigation programs were introduced in the United States to address inequitable access to cancer care. Programs have since expanded internationally and in scope. The goals of patient navigation programs are to: a) link patients and families to primary care services, specialist care, and community-based health and social services (CBHSS); b) provide more holistic patient-centred care; and, c) identify and resolve patient barriers to care. This paper fills a gap in knowledge to reveal what is known about motivators and factors influencing implementation and maintenance of patient navigation programs in primary care that link patients to CBHSS...

Visceral leishmaniasis (VL) is an important neglected disease caused by a protozoan parasite, and represents a serious public health problem in many parts of the world. It is zoonotic in Europe and Latin America, where infected dogs constitute the main domestic reservoir for the parasite and play a key role in VL transmission to humans. In Brazil this disease is caused by the protozoan Leishmania infantum chagasi, and is transmitted by the sand fly Lutzomyia longipalpis. Despite programs aimed at eliminating infection sources, the disease continues to spread throughout the Country...

: Alzheimer's disease (AD) is characterized by the presence of parenchymal amyloid-β (Aβ) plaques, cerebral amyloid angiopathy (CAA) and neurofibrillary tangles. Currently there are no effective treatments for AD. Immunotherapeutic approaches under development are hampered by complications related to ineffectual clearance of CAA. Genome-wide association studies have demonstrated the importance of microglia in AD pathogenesis. Microglia are the primary innate immune cells of the brain...

Biomimetics applies principles and strategies abstracted from biological systems to engineering and technological design. With a huge potential for innovation, biomimetics could evolve into a key process in businesses. Yet challenges remain within the process of biomimetics, especially from the perspective of potential users. We work to clarify the understanding of the process of biomimetics. Therefore, we briefly summarize the terminology of biomimetics and bioinspiration. The implementation of biomimetics requires a stated process...
