To evaluate the effects of grinding and polishing on surface characteristics of monolithic zirconia fabricated by two different manufacturing processes.
Two types of monolithic zirconia specimens, self-glazed zirconia (SZ) and conventional zirconia (CZ), were fabricated by wet deposition and dry milling, respectively. The specimens were randomly assigned into 4 groups (n = 10) as-sintered, ground, polished with a special zirconia polishing kit, and polished with a general-purpose ceramic polishing kit. Surface morphology and roughness (R
) were characterized, followed by one-way ANOVA analysis (α = 0.05).
The as-sintered SZ exhibited a smooth surface with obvious different morphologies compared with the as-sintered CZ (R
0.26 ± 0.05 μm versus 0.33 ± 0.10 μm). R
of the ground SZ was significantly higher than that of the as-sintered SZ (p < 0.001) and the ground CZ (p = 0.011). For both SZ and CZ, R
decreased significantly after polishing (p < 0.001), and there was no significant difference between the two groups with different polishing kits (SZ- p = 0.144; CZ- p = 0.322). Surface morphologies of SZ and CZ became similar after grinding and polishing.
Monolithic zirconia SZ fabricated by wet deposition exhibited a smooth surface with specific patterns compared to the dry milled CZ. Grinding significantly changed the surface morphology of SZ and increased surface roughness of both zirconia specimens, which can be improved by polishing without being influenced by polishing kit selection.

Pyoderma gangrenosum (PG) is a rare inflammatory skin condition characterized by painful, irregularly shaped skin ulcers mainly affecting the lower extremities. PG rarely affects the head and neck, making the diagnosis of this condition even more challenging. A high index of suspicion is paramount in the diagnosis of PG, especially after surgical procedures.
We describe a clinical case of a patient with initially undiagnosed PG of the scalp who underwent surgical excision and full thickness skin graft with subsequent graft necrosis as initial clue for the diagnosis.
Twenty months after initial presentation, this patient healed with a multimodal medical approach of immunosuppressive therapy and wound care.
Prompt recognition of PG by physicians assessing any surgical wounds is vital in reducing misdiagnosis and improving patient outcomes.

This exploratory study investigates if intra-articular injected gold microparticles in knee osteoarthritis (KOA) reduce immunomodulatory-based pain via proteomic changes in the synovial fluid (SF) and serum.
Thirty patients with moderate KOA were included. Intraarticular injections with 20mg gold microparticles (72.000 particles, 20-40µm in diameter) using the patient's synovial fluid (SF) as carrier were performed. Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) subscores for pain, stiffness, and function were assessed at inclusion, 8weeks and 2years The PainDetect questionnaire, pain pressure threshold (PPT), temporal summation (TS), and conditioned pain modulation (CPM), and pain diary were assessed at inclusion and 8weeks. Proteome analysis was performed on SF and blood samples before and after 8weeks of treatment.
A decrease in WOMAC scores (pain (p=0.0001), stiffness (p=0.0088), activity (p=0.0001)), PainDetect (p=0.0002) and increase in PPT (p=0.001) and CPM (p=0.021) and atreatment of inflammation and pain.
This study indicates that intra-articular gold may provide advantages in clinical practice for managing knee osteoarthritic pain. C25140 The use of intraarticular gold can add new knowledge to the treatment of inflammation and pain.
The purpose of this study was to investigate the lived experience of parenting or caring for a person with a disability receiving services under the National Disability Insurance Scheme in rural Australia.
Qualitative study guided by the phenomenology of practice.
Rural areas of New South Wales (MM 3-7).
Participants were 5 parents and one carer of people receiving National Disability Insurance Scheme services who resided in rural New South Wales.
Participants engaged in a semi-structured interview about their lived experiences caring for someone accessing services under the National Disability Insurance Scheme in rural New South Wales. Interviews were audio-recorded, transcribed verbatim and analysed thematically.
Three themes emerged from the data analysis. 'More than a disability' described the absence of understanding of family and carer challenges when National Disability Insurance Scheme plans were designed and implemented. 'Fighting for funding and services' described that while the Nationamily member with a disability. The voices of parents and carers is a critical one, and it is essential that rural parents' and carers' needs are considered and supported in future planning of the National Disability Insurance Scheme.Workplaces have been identified as a priority setting for the delivery of wellness programs to address risk factors for overweight and obesity. Men in particular may benefit greatly from these types of programs as they are typically harder to engage in health promotion. A scoping review was performed to provide an overview of interventions that have been implemented within the workplace that target weight outcomes in men. A searched of six electronic databases (Medline, Embase, CINAHL, Scopus, Cochrane Database of Systematic Review, and Business Source Ultimate) was conducted from January 2010 to August 2020. Of the 2191 articles identified, 25 were included. The majority took place in North America or Europe (72%). Over half (n = 17, 68%) utilized both a nutrition and physical activity component. Thirteen of the 19 articles (68%) that reported weight as an outcome showed the program to be efficacious in reducing weight. Overall, only seven articles were solely focused on an all-male population. Workplace wellness programs targeting weight outcomes in men have been conducted to some extent, with majority being successful in reducing weight. However, there is a need for more randomized controlled trials (RCTs), long-term follow-up, and male-only programs.Nano-enabled, bio-based, functional materials are key for the transition to a sustainable society as they can be used, owing to both their performance and nontoxicity, to gradually replace existing nonrenewable engineering materials. Cellulose nanocrystals (CNCs), produced by acid hydrolysis of cellulosic biomass, have been shown to possess distinct self-assembly, optical, and electromechanical properties, and are anticipated to play an important role in the fabrication of photonic, optoelectronic, and functional hybrid materials. To facilitate CNCs' technological viability, a method suitable for industrial exploitation is developed to produce photonic films possessing long-range chirality on conductive, rigid, or flexible, substrates within a few minutes. The approach is based on electrophoretic deposition (EPD)-induced self-assembly of CNCs, where photonic films of any size can be produced by controlling CNC surface properties and EPD parameters. CNC film coloration can be determined by the CNC aqueous suspension characteristics, while their reflected intensity can be tuned by changing the duration and number of electrodeposition cycles. EPD-induced self-assembly of CNCs is compatible with in situ reduction of gold precursors without the need to use additional reducing agents (some of which are considered toxic), thereby allowing the preparation of hybrid photonic films with tunable plasmonic response in a one-pot process.Triphenylamine (TP) derivatives such as two-branch cationic vinylbenzimidazolium triphenylamine TP-2Bzim are promising turn-on fluorescent probes suitable for two-photon imaging, labelling mitochondria in live cells. Here, we designed two TP-2Bzim derivatives as bimodal probes suitable for X-ray fluorescence imaging. The conjugation of the TP core with a rhenium tricarbonyl moiety in the TP-RePyta probe altered the localisation in live cells from mitochondria to lysosomes. The introduction of bromine on the TP core generated the TP-Br probe retaining good photophysical properties and mitochondria labelling in live cells. The influence of calcium channels in the uptake of TP-Br was studied. Synchrotron Radiation X-ray Fluorescence (SXRF) imaging of bromine enabled the detection of TP-Br and suggested a negligible presence of the probe in an unbound state in the incubated cells, a crucial point in the development of these probes. This study paves the way towards the development of TP probes as specific organelle stainers suitable for SXRF imaging.Despite the availability of long-term follow-up data, the effect of pelvic osteotomy on the natural history of osteoarthritis is not yet fully understood, partly because there is untapped potential for radiographs to better describe osteoarthritis. Therefore, this study aimed to assess the distribution of subchondral bone mineral density (BMD) across the acetabulum in patients with hip dysplasia immediately (2 weeks) and 1 year after undergoing periacetabular osteotomy (PAO). To that end, we reviewed 40 hips from 33 patients with developmental dysplasia of the hip who underwent PAO between January 2016 and July 2019 at our institution. We measured subchondral BMD through the articular surface of the acetabulum using computed tomography osteoabsorptiometry, dividing the distribution map into nine segments. We then compared the subchondral BMD between 2 weeks and 1 year after PAO in each area. At 2 weeks after PAO, the high-density area tended to be localized particularly in the lateral part of the acetabulum, whereas 1 year after PAO, the high-density area moved to the central and lateral parts. The percentage ratios of the subchondral BMD for the central-posterior, lateral-central, and lateral-posterior areas relative to the central-central area were significantly decreased at 1 year after PAO, as compared to those at 2 weeks after PAO. These findings suggest that loading was altered by PAO to be more similar to physiological loading. A long follow-up observational study is warranted to confirm the association between early changes in subchondral BMD by PAO and joint degeneration.
