nses to uncertainty, and the dynamic relationship among these elements. Our framework illustrates the different aspects of knowledge as a source of uncertainty and how to distinguish between those aspects. Our framework highlights the complexity of sources of uncertainty, especially when including uncertainty arising from relationships and systems. These sources can occur in combination. Our framework is also novel in how it describes the impact of influencers such as personal characteristics, experience, and affect on perceptions of and responses to uncertainty. This framework can be used by educators and curricula developers to help understand and teach about clinical uncertainty.Photoimmunotherapy (PIT) has shown enormous potential in not only eliminating primary tumors, but also inhibiting abscopal tumor growth. However, the efficacy of PIT is greatly limited by tumor hypoxia, which causes the attenuation of phototherapeutic efficacy and is a feature of the immunosuppressive tumor microenvironment (TME). In this study, one type of brand-new artificial metalloprotein nanoanalogues is developed via reasonable integration of a "phototherapy-enzymatic" RuO2 and a model antigen, ovalbumin (OVA) for enhanced PIT of cancers, namely, RuO2 -hybridized OVA nanoanalogues (RuO2 @OVA NAs). The RuO2 @OVA NAs exhibit remarkable photothermal/photodynamic capabilities under the near-infrared light irradiation. More importantly, the photoacoustic imaging and immunofluorescence staining confirm that RuO2 @OVA NAs can remarkably alleviate hypoxia via in situ catalysis of hydrogen peroxide overexpressed in the TME to produce oxygen (O2 ). This ushers a prospect of concurrently enhancing photodynamic therapy and reversing the immunosuppressive TME. Also, OVA, as a supplement to the immune stimulation induced by phototherapy, can activate immune responses. Finally, further combination with the cytotoxic T-lymphocyte-associated protein 4 checkpoint blockade is reported to effectively eliminate the primary tumor and inhibit distant tumor growth via the abscopal effect of antitumor immune responses, prolonging the survival.
The physiotherapy profession did not escape the effects of racially based segregatory practises. While numerous strategies and initiatives have been employed to redress the inequities of the past, the extent of demographic transformation within the physiotherapy profession in South Africa remains uncertain. Transformation is defined in this article as an intentional change aimed at addressing inequalities and the ultimate goal is for population group and gender profiles of higher education graduates to be representative of the national epidemiological profile. This paper describes the demographic patterns of Health Professions Council of South Africa (HPCSA) registered physiotherapists from 1938 to 2018.

A retrospective record review of the HPCSA database from 1938 until 2018 was performed. De-identified data were extracted, coded and analyzed for descriptive purposes. Z-tests were used for analysis of proportion differences, along with P-values and 95% confidence intervals for interpretation.

In 2018, pt for local context.
There has been a steady transformation of the South African physiotherapy graduates composition regarding population categories and gender. However, it is clear that much more than selection criteria is needed to transform the profession in a way that is nationally representative, remain actively accountable for transformation and apt for local context.The present era accentuate the use of alternative medicines as drugs extracted from several plant parts. These herbal medicines otherwise called ethnomedicines are now the source of many imperative drugs in this contemporary world. Furthermore with ever rising oral problems by luxurious lifestyle in this modern society, there is a soaring need for use of potent medicinal plants like horse radish (Moringa oleifera Lam.) against various oral ailments. Therefore, use of herbal medicines in reducing the adverse effects of various conventional allopathic medicines and harmful side effects of conventional antibiotics has emerged as an evolved technique in pharmaceutical science. The present review emphasizes the antipathogenic potentiality of M. oleifera along with their known therapeutic properties through biologically active compounds (phytoconstituents) and ethnomedicinal uses. Various ethno-pharmacological studies of the plant parts with their nutritional value and multifarious medicinal uses including oral health care are being quoted in present review. This review will foster future research on phytoconstituent analysis, bioefficacy assessment for oral micro flora and ethno-pharmaceutical importance of M. oleifera in the field of medical science with special reference to dentistry. Consequently, this innovative ethnomedicinal approach for oral health care may supplement the modern medicine through its potent phytoconstituents.
To elucidate the differences in autonomic dysfunction between dementia with Lewy bodies (DLB) and Alzheimer's disease using a simple and convenient method, we investigated the heart rate response to orthostatic challenge.

Ninety-seven people participated in this cross-sectional study, and data from 26 DLB patients, 29 Alzheimer's disease patients, and 25 healthy elderly individuals were analysed. Participants underwent postural changes, including 5 min in a supine position, 1 min in a sitting position, and 3 min in an orthostatic position. Their heart rates were continuously recorded. Two heart rate variables were analysed as main outcomes (i) the difference between heart rate in the sitting position and the peak heart rate within 15 s of orthostasis, defined as the 'early heart rate increase'; and (ii) the difference between the peak heart rate and the negative peak heart rate after this, defined as 'early heart rate recovery.' An early heart rate increase has been considered to reflect parasympathetic aDLB. Electrocardiogram is a convenient, non-invasive method that might be useful as a subsidiary marker for DLB diagnosis and differentiation from Alzheimer's disease.A bifunctional oxygen evolution reaction (OER) mechanism, in which the energetically demanding step of the attack of hydroxide on a metal oxo unit is facilitated by a hydrogen atom transfer to a second site, has the potential to circumvent the scaling relationship. However, the bifunctional mechanism has hitherto only been supported by theoretical computations. Here we describe an operando Raman spectroscopic and electrokinetic study of two highly active OER catalysts, FeOOH-NiOOH and NiFe layered double hydroxide (LDH). The data support two distinct mechanisms for the two catalysts FeOOH-NiOOH operates by a bifunctional mechanism where the rate-determining O-O bond forming step is the OH- attack on a Fe=O coupled with a hydrogen atom transfer to a NiIII -O site, whereas NiFe LDH operates by a conventional mechanism of four consecutive proton-coupled electron transfer steps. The experimental validation of the bifunctional mechanism enhances the understanding of OER catalysts.Materials with tunable long persistent luminescence (LPL) properties have wide applications in security signs, anti-counterfeiting, data encrypting, and other fields. However, the majority of reported tunable LPL materials are pure organic molecules or polymers. #link# Herein, a series of metal-organic coordination polymers displaying color-tunable LPL were synthesized by the self-assembly of HTzPTpy ligand with different cadmium halides (X=Cl, Br, and I). In the solid state, their LPL emission colors can be tuned by the time-evolution, as well as excitation and temperature variation, realizing multi-mode dynamic color tuning from green to yellow or green to red, and are the first such examples in single-component coordination polymer materials. Single-crystal X-ray diffraction analysis and theoretical calculations reveal that the modification of LPL is due to the balanced action from single molecule and aggregate triplet excited states caused by an external heavy-atom effect. The results show that the rational introduction of different halide anions into coordination polymers can realize multi-color LPL.
This study aimed to investigate whether an increased proton pump inhibitor (PPI) dose enhanced the efficacy of Helicobacter pylori (H.pylori) eradication and determine the appropriate cutoff intragastric pH value that could predict H.pylori eradication with bismuth-based quadruple therapy.

A total of 207 H.pylori infected, treatment naive patients were enrolled in this prospective, open-label, randomized controlled trial. Patients were randomly allocated into Eso40-group (esomeprazole 40mg bid) and Eso20-group (esomeprazole 20mg bid), and their CYP2C19 genotyping status was assessed. The 24-h intragastric pH monitoring on day 7 was performed, and percentage of time gastric pH≥3, ≥4, ≥5, and ≥6 (pH holding time ratios; HTRs) were measured. H.pylori eradication was evaluated using
C-urea breath test.

No significant difference in the eradication rates was observed between two groups. The median 24-h intragastric pH value was not significant different between two groups but the Eso40 Group had a significn.
Bismuth-based quadruple therapy resulted in high H. link2 pylori eradication rates either in PPI standard or double doses. Double dose of esomeprazole is associated with better intragastric acid suppression. link3 A median 24-h intragastric pH of 5.7 could be appropriate cutoff value for predicting the successful H. pylori eradication.The Pediatric Preclinical Testing Program (PPTP) previously reported the activity of the EZH2 inhibitor tazemetostat (EPZ6438) against xenograft models of rhabdoid tumors. Here, we determined whether an inhibitor of EZH2 enhanced the effect of standard of care chemotherapeutic agents irinotecan, vincristine, and cyclophosphamide. EPZ011989 significantly prolonged time to event in all the six rhabdoid models studied but did not induce tumor regression. The addition of EPZ011989 to standard of care agents significantly improved time to event in at least one model for each of the agents studied, although this effect was observed in only a minority of the combination testing experiments.The molecular processes that accompany dynamic mechanical response to large deformations at high strain rate (≈1000 s-1 or higher) underlie the early stages of damage in materials, but understanding of material response in this regime is typically limited to macroscopic constitutive equations. Here, spiropyran mechanophores are embedded in very short, stress-bearing strands in silicone elastomers, and their mechanochromic response to uniaxial compression is explored in a Split Hopkinson Pressure (or Kolsky) Bar. At WithaferinA of 1000 s-1 , the onset of mechanochromism occurs at lower strains, but higher stresses, than in the same materials under quasi-static loading. Similar to quasi-static loading, however, a negligible effect of mechanophore structure on the critical strain for colorimetric onset is observed. The results suggest that nonequilibrium, inhomogeneous local tension distributions in the elastomers lead to greater stress in individual strands than at the same strains under equilibrium loading, but that within the regions of force concentration, mechanochromic onset is determined primarily by a limiting local strain threshold.
