Functionality of Enynic and also Allenic Orthoesters by way of Defluoromethoxylation of 2-Trifluoromethyl-1,3-enynes.
Cluster 2 showed scores below the mean in both math scores, whereas cluster 3 exhibited performances above the mean in both math scores. No math differences were found between cluster 1 and 3. The data yield evidence that the association between CEF and math achievement depends on the specific math skill and test type. The results underline the importance of differentiating between CEF components and specific math abilities. Implications for future research on the associations between mathematics, ADHD and CEF are discussed.Background Maternal stress during pregnancy can influence the trajectory of fetal development, shaping offspring physiology and health in enduring ways. Some research implicates fetal programming of the hypothalamic-pituitary-adrenocortical (HPA) axis as a mediator of these effects. The present study is the first to examine child hair cortisol concentration (HCC) and maternal stress during pregnancy in a diverse, low-income sample. Methods The sample consisted of 77 healthy, low-income (M annual income $13,321), mother-children pairs (M child age = 3.81 years, SD = 0.43). The children were 57 % girls, 43 % boys. Mothers were 65 % Latina/Hispanic, 28 % Non-Hispanic White, 7% Black/African American. Maternal prenatal stress was measured with the Perceived Stress Scale administered by interview in the second and third trimesters, and again approximately four years later when child hair samples for assaying HCC were collected. Results On average maternal perceived stress increased significantly across pregnancy, then returned to lower levels 4 years after birth. Regression analysis revealed that child HCC was not significantly predicted by maternal perceived stress at either single prenatal time point. Exploratory analysis revealed evidence of a relation between increases in maternal prenatal stress from second to third trimester and child HCC four years later (r = .37, p = .04). Conclusions These results suggest that measures of prenatal maternal stress at any one time point may not be predictive of offspring long-term HPA output in low-income child samples, but that increases in stress levels across pregnancy may provide important information undetected by individual time point measures.This cross-sectional study aims to investigate awakening cortisol indicators and to explore their association with stress perception, advanced glycation end products (AGEs), depression and anxiety in parents of children with chronic conditions. We included five parental groups according to children's diagnoses Down syndrome (DS; N = 31), autistic spectrum disorder (ASD; N = 29), cerebral palsy (CP; N = 15), diabetes mellitus type 1 (DMT1; N = 38), and a control group of heathy children (CG; N = 33). Salivary cortisol and AGEs were measured, alongside with psychological indices. Partial correlation and multiple linear regression were used in the analysis to identify parental characteristics associated with total awakening cortisol output (area under the curve with respect to the ground, AUCG), cortisol awakening response (area under the curve with respect to the increase, AUCI), perceived stress, and health outcomes (AGEs, depression and anxiety). There was no difference between groups for AUCG, while DS and DMT1 groups showed reduced AUCI (β = -0.241, p = 0.040; β = -0.249, p = 0.028, respectively), and ASD parents had a borderline insignificant result (β = -0.205, p = 0.081). Non-smokers had higher AUCG, and parental sedentary activity and sleep duration were associated with AUCI. AUCG was positively associated with AGEs (β = 0.218, p = 0.013), anxiety (β = 0.207, p = 0.004), and with depression (β = 0.156, p = 0.034), unlike the AUCI. DS parental group showed lower general stress perception (β = -0.260, p = 0.005). Parents of children with DMT1 had more pronounced depressive symptoms (β = 0.183, p = 0.039), while CP parents had a borderline insignificant result for depression (β = 0.143, p = 0.058). Based on these results, parents of children with chronic conditions have altered awaking cortisol response and are under increased risk of adverse health consequences.Platycodonis Radix, the root of Platycodon grandiflorum (Jacq.) A. DC., is a well-known edible herbal medicine. It is a common vegetable used for the preparation of side dish, kimchi, dessert, and tea. Besides, it has been used to treat respiratory disease including cough, excessive phlegm, and sore throat for a long history. In the past decades, the bioactive components and the pharmacological activities of Platycodonis Radix have been widely investigated. Thereinto, platycodins, the oleanane-type triterpenoid saponins were demonstrated to be the main bioactive components in Platycodonis Radix, and more than 70 platycodins have been identified up to date. This paper mainly reviewed the phytochemistry, pharmacological activities (apophlegmatic, anti-tussive, anti-inflammatory, anti-cancer, anti-obesity, anti-diabetic, immunomodulatory, cardiovascular protective, and hepatoprotective activities, etc.), toxicology and pharmacokinetics of platycodins isolated from Platycodonis Radix, aiming to promote further investigation on therapeutic potential of these platycodins.Black and green tea are popular owing to their unique flavors and health benefits. However, these teas can be contaminated with anthraquinones, which are associated with health risks in humans. Levels of 9,10-anthraquinone were determined at each step of the manufacturing process for green and black tea using gas chromatography-tandem mass spectrometry. For green tea, anthraquinone was present beginning at the withering process and increased in concentration until the first drying step. Additionally, for black tea, the first drying step resulted in a significant increase in anthraquinone content, whereas the concentration decreased during the final drying step. For black tea, anthraquinone was also detected during withering, although the concentration continued to increase throughout the entire procedure, particularly during drying. Selleckchem GS-9973 Therefore, it can be suggested that the presence of anthraquinone in these teas was influenced by the smoke emitted by the wood fires used to drive the processing machinery.
