Ecological Processes 2024年第1期 25-39页

Background Stone pine(Pinus pinea), a drought-resistant species, has significant socio-economic benefits and increasing interest for the establishment of productive plantations in several countries, especially in a climate change context. Monitoring hourly stem diameter variations contributes to the understanding of the tree-growth response to changes in environmental conditions and management. By monitoring the diameter expansion of tree stems, high-resolution band dendrometers were used to study the development of adult trees growing in a semi-arid coastal environment of central chile under fertilized and non-fertilized soil conditions through the span of a *** Short cycles(ctively), whereas long cycles(> 28 h) occurred at a higher frequency in fertilized trees(16 vs 6). Most of the circadian cycles were regular(24 ± 3 h). The longest cycle duration(59 h) was observed in fertilized trees during spring. In all seasons, each phase of the circadian cycle, especially during the stem diameter increment phase(P3, irreversible growth), started earlier in fertilized than in control trees. P3 duration was significantly longer in fertilized than in control trees in springtime. The maximum shrinkage(P1) was observed in summer for both treatments. Stem diameter increased faster in fer-tilized than in control trees throughout the year, with the highest accumulation occurring in spring and the lowest in autumn. The daily variability pattern showed lower growth under high temperature across *** This study highlights the importance of fertilization in enhancing stone pine diameter growth. This cultural practice should be further explored to contribute to the mitigation of climate change effects in semi-arid environments.

Evidence-Based complementary and Alternative Medicine Effects of capybara Oil on cardiac Remodeling of c57bl/6 Mice

Journal of Biosciences and Medicines 2024年第5期12卷 213-232页

cardiovascular diseases are the main cause of morbidity and mortality in the world, and obesity and the metabolic syndrome are risk factors for its development. One of the therapies to reduce cardiovascular risk is the use of polyunsaturated fatty acids. In Brazil, a source of such acid is the oil extracted from the fat of the capybara. The objective of this work is to study the effects of the capybara oil on lipid and glucose metabolism, as well as its effects on the adipose tissue and cardiac remodeling. We assessed the effects of capybara oil treatment on body mass, lipid and carbohydrate metabolism, systolic blood pressure, adipose tissue and cardiac remodeling, and performed an ultrastructural evaluation of the myocardium in c57Bl/6 mice treated with high-fat diet. Treatment with capybara oil reduced total cholesterol and triglyceride levels, systolic blood pressure, visceral and subcutaneous adipose tissue, and adipocyte diameter. In addition, cardiac remodeling was attenuated, preserving cardiomyocytes, increasing vascularization, reducing cardiomyocyte hypertrophy and the extracellular matrix, and preserving the morphological integrity of mitochondria. capybara oil has several beneficial effects on the cardiovascular and metabolic system, and further studies are needed to better understand its role in the prevention or treatment of cardiovascular diseases.

Background: The protective role of (poly)phenols against metabolic disorders has been extensively studied in adults but not in ***: To assess associations of dietary (poly)phenols and their subclasses with cardiometabolic health parameters in adolescents. Methods: A cross-sectional study was conducted in 944 individuals aged 11 to 14 years enrolled in the SI! Program for Secondary Schools trial (NcT03504059). (Poly)phenol intake was assessed using semi-quantitative food frequency questionnaires and the Phenol-Explorer database. The measured cardiometabolic parameters were waist circumference (Wc) age-sex z-score， blood pressure (BP) age-sex z-score， blood glucose (BG)， triglycerides (TG)， and high-density lipoprotein cholesterol (HDL-c). Multilevel mixed-effect linear regression models were applied to examine the association between (poly)phenol quintiles and cardiometabolic health ***: compared to the lowest quintile， adolescents in the highest quintile of total (poly)phenol intake had lower Wc z-scores (β=-0.09， 95%cI=-0.09;-0.08， P-for trend=0.002)， mean arterial pressure z-scores (β =-0.11， 95%cI=-0.12;-0.09， P-for trend=0.206)， and HDL-c (β=-1.52， 95%cI=-2.90;-0.14， P-for trend=0.108)， after multivariable adjustment. The Wc z-scores (β=-0.11， 95%cI=-0.19;-0.03， P-for trend=0.013) and HDL-c (β=-2.16， 95%cI=-3.78;-0.53， P-for trend=0.046) were lower in the highest quintile of flavonoid intake compared to the lowest quintile. The highest quintile of phenolic acid intake was associated with a lower Wc z-score (β=-0.14， 95%cI=-0.26;-0.02， P-for trend=0.011) and TG levels (β=-8.83， 95%cI=-12.37;-5.30， P-for trend cI= -3.103;-0.64， P-for trend cI= -4.95;-1.49， P-for trend=0.034)， and with higher HDL-c (β=2.328， 95%cI= 1.40;3.17， P-for trend=0.466) compared to the lowest quintile. conclusion: A higher intake of (poly)phenols， espe
