Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC) experiments were performed to study their thermal properties. A statistically significant increase in flexural strength was found in the 0.5, 0.75 and 1% composite groups after 6 h ball-milling, relative to the control, with the 6 h ball milling mixed specimens, presenting the highest flexural strength values. The brittle fracture type was common to all groups. An obvious improvement of the mechanical properties and a slight improvement in the thermal stability of the composite materials values were also observed as β-CPP content was increased, while Tg values were statistically not-affected.

To investigate the effect of blue light photoactivated riboflavin modified universal adhesives on dentin collagen biodegradation resistance, dentin apparent elastic modulus, and resin-dentin bond strength with interfacial morphology.

Dentin slabs were treated with 0.1% riboflavin-5-phosphate modified (powder added slowly while shaking and then sonicated to enhance the dispersion process) Universal Adhesive Scotch Bond and Zipbond™ along with control (non-modified) and experimental adhesives, photoactivated with blue light for 20s. Hydroxyproline (HYP) release was assessed after 1-week storage. Elastic-modulus testing was evaluated using universal testing machine at 24h. Resin-dentin interfacial morphology was assessed with scanning electron-microscope, after 6-month storage. 0.1% rhodamine dye was added into each adhesive and analyzed using CLSM. Detection of free amino groups was carried out using ninhydrin and considered directly proportional to optical absorbance. Collagen molecular confirmation was def being lowest for control UA Scotch bond adhesive specimens and increasing in Amides, proline, and CH

intensities in 0.1%RF modified adhesive specimens. All 0.1%RF application groups showed statistically significant (p<0.05) less levels of HYP released compared to controls. Dentin E

of riboflavin application was significantly (p<0.05) more as compared to control groups.

Blue light photoactivated 0.1% riboflavin modified adhesives improved the biochemical and biomechanical properties of demineralized dentin as well as the long-term resin-dentin interfacial integrity and bond strength of universal adhesive to dentin.

The Global Matrix of report card grades on physical activity serves as a public health awareness tool by summarising the status of child and youth physical activity prevalence and action. The objectives were to (1) provide a detailed examination of the evidence informing the 'School' and 'Community and Environment' indicators across all participating European Global Matrix 3.0 countries; (2) explore the comparability of the grades for these two indicators across Europe; (3) detail any limitations or issues with the methods used to assign grades; and (4) provide suggestions on how future grading of the indicators could be improved.

A comparative review of published methods on the grading of Global Matrix 3.0 indicators across European countries.

Key documents relating to the European countries involved in the 2018 Global Matrix 3.0 were collated and a template used to extract data for both the 'School' and 'Community and Environment' indicators.

Seventeen of the 20 European Report Card countries (85%) ntries, where possible. Such action will ultimately make the Global Matrix a more robust and useful tool for the future.

The 12-item Chinese Health Questionnaire (CHQ-12) has been widely used for screening mental disorders. This study aims to examine the internal consistency and factor structure of CHQ-12 and its suitability for use in the elderly Chinese population.

This is a cross-sectional study.

A total of 8526 elderly people aged ≥60 years from 11 cities in Shanxi Province were selected for participation in this study by stratified random cluster sampling. Cronbach's alpha was employed to assess internal consistency. An exploratory factor analysis (EFA) was performed to explore the underlying factor structure of the CHQ-12 in the elderly. A confirmatory factor analysis (CFA) was then conducted to test and compare the goodness-of-fit between possible factor structure obtained from the EFA and the unidimensional structure, which was originally recommended.

The Cronbach's alpha for CHQ-12 was 0.838. The EFA extracted three factors, which explained 55.985% of the total variance of the data. The CFA of the three-factor ects of mental health somatic symptoms, anxiety and worry, and depression/poor family relationship.

To prospectively study the prevalence of photoparoxysmal response (PPR) and its determinants in epilepsy patients.

Consecutive patients, older than 2 years, undergoing EEG from January 2016 to December 2019 were prospectively studied for the presence of PPR. Patients with emergent EEG and those with only sleep record were excluded. Intermittent photic stimulation was performed as per standard techniques with frequencies from 1-30 Hz.

Of the 1893 subjects included, 1492 (78%) patients had epilepsy while 401 (22%) had other diagnoses. In epilepsy group, 1028 (68.7%) had focal epilepsy, 343 (21.6%) had generalized epilepsy, while (9.7%) patients had unclassified epilepsy. Overall, 36 (2.2%) patients with epilepsy had PPR. The mean age of these patients was 19.5 ± 9.4 years and 75% were females. DL-Alanine compound library chemical PPR was noted in 5 (0.5%) patients with focal epilepsy and 31 (9%) patients with generalized epilepsies [p < 0.0001; Odds ratio 20.3 (95% CI, 7.8 - 52.7)]. PPR was noted in 1.5% of treated and 18% of untreated patients with genetic generalized epilepsy (n = 145) and 22% of untreated patients with juvenile myoclonic epilepsy (n = 86). Patients with untreated epilepsy had 17 times higher odds of having PPR [p < 0.0001; Odds ratio 17.6 (95% CI, 4.1 - 75.6)].

Underlying epilepsy syndrome and treatment status are the two most important determinants of PPR. Variability in these two factors is largely responsible for the variable reported prevalence of PPR.
