1Height-to-diameter ratios with temporal and dendro/morphometric variables for Brazilian pine in south Brazil显示文摘Height-to-diameter ratios(HD)are an important measure of the stability,density and competition of forest stands.It refl ects the vertical growth of the trees,the vulnerability of the forest canopy structure and infl uences volumetric production.HD ratios vary according to tree size,availability of resources for growth,stand density and species composition.Data were taken from 210 trees and a regression technique of generalized linear models for the HD ratio applicable for forest structure conservation was developed.The objective of this study was to model the HD ratios of dominant and co-dominant trees of Araucaria angustifolia according to morphometric,dendrometric,annual diameter increment,stand density,and age variables in three sites in southern Brazil.The results show that the HD ratio decreases with increasing age,crown area and basal area,and increases with stand density and annual diameter increment.Accuracy of the developed equations was demonstrated by the values of deviation,Bayesian and Akaike criteria.The results are of interest to forest managers since they make decisions about silvicultural operations.Growth continuity and forest production indicate that any intervention should be directed at younger trees of smaller sizes,and that one of the main management factors for stand stability and growth is the formation of the stand and its capture of light.Andre Felipe Hess Myrcia Minatti Emanuel Arnoni Costa Luis Paulo Baldissera Schorr Gabriel Teixeira da Rosa Isadora de Arruda Souza Geedre Adriano Borsoi Veraldo Liesenberg Thiago Floriani Stepka Roberta Abatti 2021Journal of Forestry Research2021,32,1:2

82-aminoethyl Dihydrogen Phosphate as a Modulator of Proliferative and Apoptotic Effects in Breast Cancer Cell Lines显示文摘Background: Breast cancer is a type of cancer that affects more women throughout the world, in developing anddeveloped countries. 2-AEH2P is a phospholipid analog of cellular membrane, which makes it different from existing molecules fortheir absorption, stability and display anti-inflammatory, anti-proliferative and pro-apoptotic properties. Methods: MCF-7 humanbreast adenocarcinoma cells were treated with 2-AEH2P. The viability and adhesion cells were evaluated by MTT assay. Cell cyclephases, apoptosis, markers and mitochondrial potential were assessed by flow cytometry. Morphological ultrastructural analyzeswere performed by laser confocal microscopy. Results: MCF-7 Tumor cells acquired round shapes, lost cytoplasmic expansions,formed clusters in suspension and decreased significantly viability. There were changes in the morphology, membrane fragmentationand loss of cytoplasmic projection. The obtained concentrations for IC50% were 37.2;25.8;1.8 mM for periods of 24, 48 and 72 h,respectively. Changes in the distribution of cell population phases of the cell cycle showed an increase in fragmented DNA and anincrease in the G2/M phase. The expression β-gal showed proliferative reduction induced by 2-AEH2P. Laser confocal microscopyshowed changes in the mitochondrial membrane and alteration in distribution. Proliferative index of MCF-7 tumor cells treated with2-AEH2P decreased significantly when compared to fibroblast normal cells. The compound 2-AEH2P is a phospholipid withantiproliferative potential and apoptosis modulator.Manuela Garcia Laveli da Silva Laertty Garcia de Sousa Cabral Monique Gonçalves Alves Thais deOliveira Conceição Henrique Hesse Rosa Andrea Nogueira Laiso Daniel da Conceição Rabelo Durvanei Augusto Maria 2021Journal of Pharmacy and Pharmacology2021,9,3:1
