Chiral crystalline sponges (CCSs) are a recent class of chiral porous metal complexes potential in chiral recognition. Here we report the fabrication of polysiloxane OV-1701 incorporated CCS-3S (PSO/CCS-3S) coated capillary column as a novel stationary phase for gas chromatographic separation of diverse race-mates. CCS-3S with the chiral ligand of (S)-mandelic was selected as the model CCS. With the aid of polysiloxane OV-1701, PSO/CCS-3S coated capillary column gave improved resolution, broader enantiomers separation scope and much larger McReynolds constants than CCS-3S coated capillary column. Many racemates that cannot be separated on CCS-3S coated capillary column were well resolved on PSO/CCS-3S coated capillary column. The PSO/CCS-3S coated capillary column also gave wide linear range, low limit of detection, good repeatability and reproducibility, and fine inertness and anti-column bleeding properties for the separation of enantiomers. In addition, the PSO/CCS-3S coated capillary column presented better resolution for the studied racemates than commercial beta-cyclodextrin based Cyclosil B (30 m long x0.32 mm i.d. x 0.25 mu m film thickness), beta-DEX 225 (30 m long x0.25 mm i.d. x 0.25 mu m film thickness) and amino acid based Chirasil L-Val (25 m long x0.25 mm i.d. x 0.12 mu m film thickness) capillary columns. These results indicate the great potential of PSO/CCS-3S coated capillary column in separation of enantiomers. (C) 2019 Elsevier B.V. All rights reserved.

Background: To perform a morphologic classification based on the results of bone augmentation after a distraction osteogenesis. Material and Methods: Thirty-four (34) patients (24 women and 10 men; mean age, 47.1 years (SD=9.5); age range, 23 to 62 years) underwent a total of 42 alveolar ridge distractions before the placement of a total of 89 dental implants. Ridge bone morphology was evaluated as the main ordinal variable. Chi-squared, Kruskal-Wallis and ANOVA one-way test were used. Results: Category I (30.95%): consisted of wide alveolar rim and no bone defects Category II (28.57%): wide alveolar rim, lateral bone surface concavity. Category III (23.81%): narrow alveolar rim, lateral bone surface concavity. Category IV (2.38%): distraction transport segment forming a bridge, without bone formed beneath and requiring guided bone regeneration. Category V (9.52%): return of the transport segment to its initial position due to the reverse rotation of the distractor screw. Category VI (4.76%): distraction transport segment completely lost. Subcategory D (28.57%), consisted of lingual deviation of the distraction axis, occurring in any of the categories I to IV. More men (76.9%) presented with category I (p<0.001). The use of the chisel resulted mainly in categories I and II (69.4%) (p<0.001). GBR was only required in 23.1% of the cases in Category I (p=0.011). The bone height achieved decreases as the category increases, due to the accompanying osteogenic limitations (p<0.001). The implants placed in category I were longer 11.5 +/- 0.9 mm (CI95% 10.9-11.9 mm) compared to those placed in category III with a length of 10.4 +/- 1.5 mm (CI95% 9.5-11.4 mm) (p=0.035). Conclusions: The alveolar ridge after distraction osteogenesis could be divided into six morphologic categories which provide a useful basis for decision-making regarding implant placement.

Our main aims were to assess haemoglobin (Hb) concentrations from preoperative assessment to discharge from hospital, and to review which patients had blood transfusions and compliance with national transfusion guidelines. We studied a consecutive series of 131 patients between October 2016 and September 2017 who had either neck dissection or resection and free microvascular tissue transfer. Half the patients had soft tissue free flaps (n=65), 26% had composite free flaps (n = 34), and 24% neck dissection only (n =32). Using the WHO definition of anaemia, 4% (1/28) of patients who had neck dissections and 19% (16/85) of those who had free flaps were anaemic preoperatively. The median (IQR) Hb at discharge was 131 (119-144) g/L for patients who had neck dissections, 103 (95-114) g/L for those who had soft free flaps, and 95 (90-104) g/L for those who had composite free flaps. No patients who had neck dissection were given a red blood cell (RBC) transfusion, whereas they were given to 26/99 (26%) of those who had free flaps. Hb concentrations were checked after each unit in 31/39 transfusions (79%). Concentrations for those who had free flaps fell by about 30 g/L from admission to operation, and only four patients were given tranexamic acid peroperatively. Postoperatively Hb remained at similar concentrations until discharge, with 23/98 (24%) given iron orally on discharge. In terms of compliance with blood transfusion guidelines there was a notable absence of the use of tranexamic acid and of iron intravenously. An increase in their use could potentially reduce the number of blood transfusions required and the postoperative incidence of anaemia, and have a favourable effect on outcomes such as complications, fatigue, and overall quality of life.

The focus of Cosmetics Europe’s programme on serious eye damage/eye irritation is on development of testing strategies and defined approaches for identification of ocular effects of chemicals in the context of OECD’s Guidance Document on an Integrated Approach on Testing and Assessment (IATA) for Serious Eye Damage and Eye Irritation. Cosmetics Europe created a comprehensive database of chemicals for which in vitro data are available with corresponding historical in vivo Draize eye data. This database allowed further exploration of the initially proposed strategies from the CON4EI project and to identify opportunities for refinement. The current analysis focused on the development of a defined approach, applicable to liquid non-surfactant chemicals, neat and in dilution, that can distinguish between the three UN GHS categories (Cat. 1, Cat. 2, and No Cat.). Combining the modified-protocol Short Time Exposure (STE) test method (OECD TG 491 with extension to highly volatile substances) with the Bovine Corneal Opacity and Permeability Laser Light-Based Opacitometer (BCOP LLBO) test method in a Bottom-Up approach identified 81.2% Cat. 1, 56.3% Cat. 2, and 85.3% No. Cat correctly, with an NPV of 96.7% and a PPV of 68.6%. Therefore, the performance of the defined approach was better than the standalone test methods.

Aims: To report the results of the first national Health Examination Survey (HES) on the prevalence of diabetes, its pharmacologic treatment and level of control, as well as pre -diabetes in Greece. Methods: Data were derived from the National Survey of Morbidity and Risk Factors (EMENO), in a randomly selected, representative sample of the adult Greek population. Sampling weights were applied to adjust for study design and post-stratification weights to match sample age/sex distribution to the population. Non-response was adjusted by inverse probability weighting. Weighted prevalence estimates are provided. Results: A total of 4393 persons with HbA1c and/or fasting plasma glucose measurements were included. Total diabetes prevalence was 11.9% (95% CI: 10.9-12.9), known diabetes 10.4% (9.5-11.4), and unknown 1.5% (1.1-1.9), with considerable increase in older age groups and no difference between genders. Pre-diabetes prevalence was 12.4% (11.4-13.6). The majority of persons with known diabetes were receiving metformin. Of those with known diabetes (and measured HbA1c), 70.9% were well controlled (HbA1c <7.0%). Conclusions: This first representative national HES showed high prevalence of diabetes in Greece, with low prevalence of unknown diabetes. Pre-diabetes prevalence is also substantial. These results will hopefully enable national authorities develop tailored and efficient strategies for disease prevention and management.

We report a dual-tasked methylation that is based on cooperative palladium/norbornene catalysis. Readily available (hetero)aryl halides (39 iodides and 4 bromides) and inexpensive MeOTs or trimethylphosphate are utilized as the substrates and methylating reagent, respectively. Six types of ipso terminations can modularly couple with this ortho C-H methylation to constitute a versatile methylation toolbox for preparing diversified methylated arenes. This toolbox features inexpensive methyl sources, excellent functional-group tolerance, simple reaction procedures, and scalability. Importantly, it can be uneventfully extended to isotope-labeled methylation by switching to the corresponding reagents CD3OTs or (CH3OTs)-C-13. Moreover, this toolbox can be applied to late-stage modification of biorelevant substrates with complete stereoretention. We believe these salient and practical features of our dual-tasked methylation toolbox will be welcomed by academic and industrial researchers.

Objective. To analyze the association between relative handgrip strength (RHGS) and fat mass (FM) after controlling for the potential effect of maturity status. Methodology. Both male and female children and adolescents aged >= 7.5 to <= 15.49 years were studied. RHGS was assessed using a hydraulic hand dynamometer. FM percentage was established using a dual-energy X-ray absorptiometry. Age and sex differences in RHGS levels between normal weight and obese participants were studied with an analysis of covariance. A covariate was years from peak height velocity (maturity status). The association between RHGS and FM levels was analyzed using a partial correlation and controlling for age at peak height velocity. Results. A total of 1685 students (731 girls and 954 boys) participated. Four age groups were established (7.5-9.4 years, 9.5-11.4 years, 11.5-13.4 years, and 13.5-15.4 years). RHGS increased with age in both males and females. FM values were high in all age groups. No differences were observed in groups 3 and 4 among girls or in group 4 among boys. Participants classified as normal weight showed a significantly higher RHGS than their obese peers. A negative association was noted between RHGS and FM. Conclusion. RHGS was shown to be negatively associated with FM after controlling for the effect of maturity status. Product Details of 95-11-4.
