The success of many endosseous implants in orthopaedic and dental applications depends on the surface characteristics, as they affect osseous integration. Previous investigations indicated that a novel large-grit sand-blasted and acid-etched (SLA) titanium (denoted as SLAffinity-Ti) implant had better bone integration than that of a comparably shaped implant with a plasma-sprayed titanium surface. The purpose of the present investigation was to create a SLAffinity surface on pedicle screws and trauma screws and to compare it with the surfaces of a sand-blasted-only implant and commercial implants in terms of bone integration...

PURPOSE: To evaluate the effect of titanium (Ti) particles on oral epithelial cell homeostasis and the potential of dental implants to release Ti debris upon insertion. MATERIALS AND METHODS: Dental implants with varying surface treatments were employed to determine the feasibility of particle release during implant placement as well as the impact of free Ti debris on oral epithelial cells. Ti particles derived from implant surfaces were isolated and cultured in direct contact with normal oral epithelial cells for 48 hours...

Infection by Cryptosporidiumbaileyi causes respiratory cryptosporidiosis in red grouse Lagopuslagopusscotica. First diagnosed in 2010, it has since been detected across half of moors managed for grouse shooting in northern England. We hypothesised that contaminated grouse faeces within communal trays visited by grouse containing grit coated with flubendazole, provided to control Trichostrongylustenuis parasites of grouse, is a reservoir of infection. To establish the basis to this hypothesis, contents of 23 trays from a grouse moor were examined for Cryptosporidium oocysts...

HYPOTHESIS: It was the aim of this study to establish normative data regarding intended changes in cochlear implants (CI) receiver positioning by one surgeon over time. BACKGROUND: With the increasing number of CI patients, the probability of needing magnetic resonance imaging (MRI) increases. The accessibility of cerebral structures is limited by MRI artifacts caused by CI. New studies show a dependence of the visibility of intracranial structures by the MRI sequences and the position of the CI receiver itself...

Immune checkpoint blockade, exemplified by antibodies targeting the programmed death-1 (PD-1) receptor, can induce durable tumor regressions in some patients. To enhance the efficacy of existing immunotherapies, we screened for small molecules capable of increasing the activity of T cells suppressed by PD-1. Here, we show that short-term exposure to small molecule inhibitors of cyclin-dependent kinases 4 and 6 (CDK4/6) significantly enhances T cell activation, contributing to anti-tumor effects in vivo, due in part to de-repression of Nuclear Factor of Activated T cell (NFAT) family proteins and their target genes, critical regulators of T cell function...

Purpose: Delivery of swallowing therapy is faced with challenges regarding access to in-clinic services and adherence to prescribed home programs. Mobile health (mHealth) technologies are being developed at a rapid pace to address these difficulties. Whereas some benefits to using these modern tools for therapy are obvious (e.g., electronic reminders), other advantages are not as well understood. One example is the potential for mHealth devices and apps to enhance adherence to treatment regimens...

Objective: Self-control and grit have become two of the most important variables that explain success in different aspects of people's daily life (Duckworth and Gross, 2014). Self-control promotes delayed gratification and directly influences thoughts, emotions, and impulses. On the other hand, grit enhances the achievement of goals through perseverance even before extreme external circumstances. Since both constructs are related, examining them together is compelling, as long as the different nuances that characterize each are taken into account...

Most widely-used stress-induction procedures (such as the TSST and the Cold Pressor Test) require considerable effort and overhead in terms of preparation, logistics, and staff recruitment. Moreover, while known to reliably induce HPA axis activation, especially when combined with social self-threat, most conventional laboratory stressors cannot be flexibly adapted to elicit either a mainly autonomic or an additional endocrine stress response. Being a promising alternative approach, a new version of the isometric handgrip test enriched by a social-evaluative component was evaluated in the present study...

The design and application of a versatile and inexpensive experimental extension to NMR spectrometers is described that allows to carry out highly reproducible PHIP experiments directly in the NMR sample tube, i.e. under PASADENA condition, followed by the detection of the NMR spectra of hyperpolarized products with high spectral resolution. Employing this high resolution it is feasible to study kinetic processes in the solution with high accuracy. As a practical example the dissolution of hydrogen gas in the liquid and the PHIP kinetics during the hydrogenation reaction of Fmoc-O-propargyl-l-tyrosine in acetone-d6 are monitored...

OBJECTIVE: Maxillofacial prosthesis are supported by implants, require a retentive matrix to retain the suprastructure. The retentive matrix is made up of acrylic resin to which the silicone prostheses are anchored by micro-mechanical bond. The delamination of silicone away from the retentive matrix is a persisting problem in implant-supported maxillofacial prosthesis. AIM: This study aimed to evaluate the effect of laser etching on the shear bond strength (BS) between acrylic resin and maxillofacial silicone, after 24 h of fabrication and after 200 h of accelerated aging...

Baseline information on demographics and practices on semi-intensive free-range egg farms with an outdoor stocking density of ≤1500 hens/hectare in Australia is presented. Free-range egg production is changing the structure of the egg industry in Australia and a broad variety and tiers of free-range systems have emerged due to lack of concrete legislative standards on outdoor stocking densities in the past. Information was extracted from a pre-existing online free-range poultry survey dataset, consisting of a total of 79 questions related to nutrition, pasture management, welfare and health, animal housing, environmental impact and economics...

Other than cognitive ability, what competencies should schools promote in children? How are they organized, and to what extent do they predict consequential outcomes? Separate theoretical traditions have suggested interpersonal, intrapersonal, and intellectual dimensions, reflecting how children relate to other people, manage their own goals and impulses, and engage with ideas, respectively. However, very little work has examined character empirically. In the current investigation, we partnered with middle schools that had previously identified character strengths relevant in their communities...

In this research, carrot pulp was added to traditional snack made from corn-grit. As the biological activity of carotenoids in the body depends on their bioaccessibility, change in carotenoid bioaccessibility during extrusion processing was investigated. In addition, phenolic content, antioxidant activity, β-carotene and lutein contents were investigated before and after the extrusion process. Two different temperature profiles were used for extrusion process. In-vitro bioaccessibilities of β-carotene and lutein increased by extrusion, β-carotene at both temperature profiles while lutein only at higher temperature profile...
