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.

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.

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. Recommanded Product: 95-11-4.

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. Application In Synthesis of 5-Norbornene-2-carbonitrile.

Bioaccessibility of trace elements (Li, Be, Ti, Ga, Cu, Ag, Hg, Cd, Cs, Pt, Tl, Pb, As, Cr, Co, Ni, V, Se, Sn and Sb) and major elements (Rb, Ba, Al, Fe, Zn, Si, Ca, Mg, Mn, Mo, Sr, P and K) in tea infusions has been assessed using an in vitro dialyzability protocol. Gastric simulation (using pepsin solution) and intestinal simulation (using pancreatin and bile salts) were used to perform the in vitro digestion. ICP-MS, ICP-OES and FAES were used for elements determination in digested tea leaves, their infusions and the dialyzate fractions from tea infusions. Microwaves assisted acid digestion was used for the total element determination in tea leaves, while tea infusions were prepared by brewing tea leaves for 5 min in boiling water. The LODs for elements determined in tea leaves were in the range of 0.11-656 ng g(-1) and 0.02-145.6 mu g g(-1) for trace and major elements, respectively. For elements’ determination in tea infusions, the LODs were ranged between 0.23 and 399.9 ng L-1 for trace elements and 0.2-1248 mu g L-1 for major elements. The LODs for the elements in the dialyzable fraction varied from 0.018 to 142 mu g L-1. The accuracy of the total element determination was evaluated using certified reference materials (Tea Leaves INCT-TL-1 and Rye Grass). The analytical recoveries were also assessed for analyzed elements in digested tea leaves (95-114%) and their infusions (92-115%), showing good recoveries. Among the studied elements, K was the most abundant element in tea leaves and tea infusions in almost all samples, followed by Ca, Mg, and P. Zn, Cs, and K showed the highest dialyzability percentages up to 84%, 76%, and 54%, respectively, followed by Si and Ca and K that show moderate to high dialyzability percentages. The accuracy of the dialysis process was evaluated using a mass-balance study.
