Life forms of Amazonian palms in relation to forest structure and dynamics [PDF]

open access: yes, 1986
Two Amazonian terra firme forests present contrasting structures and palm compositions : one is characterized by tall and broadtrunked trees up to 50 m in height and 2.5 m in DBH, and by tall arborescent palms ; the other by more modest-sized trees up to

Palmitoylation‐Mediated Ubiquitination of SRPK1 Regulates Ferroptosis in High‐Fat‐Induced Erectile Dysfunction

open access: yesAdvanced Science, EarlyView.
Elevated exogenous palmitic acid promotes the S‐palmitoylation of SRPK1 in endothelial cells, a dynamic process governed by ZDHHC24 and APT1. This post‐translational modification strengthens the interaction between SRPK1 and the E3 ubiquitin ligase MIB1, thereby facilitating the proteasomal degradation of SRPK1.

Autocrine Netrin‐1 Signaling in Hepatic Stellate Cells Drives Liver Fibrosis and Diet‐Induced Metabolic Dysfunction‐Associated Steatohepatitis in Mice

open access: yesAdvanced Science, EarlyView.
Netrin‐1 expression is upregulated in hepatic stellate cells (HSCs) during metabolic dysfunction–associated steatohepatitis and injury‐mediated liver fibrosis. Secreted Netrin‐1 establishes an autocrine positive feedback loop by binding to UNC5B receptors on HSCs.

Anatomical modifications of Butia capitata propagated under colored shade nets

open access: yesAnais da Academia Brasileira de Ciências, 2018
The jelly palm plant [Butia capitata (Martius) Beccari] is a native palm of the Cerrado biome used for many purposes in northern Minas Gerais State, Brazil. Dormancy is common in palm seeds, resulting in slow and uneven germination that may take years to

Advanced Human Immune Cell‐Organoid Co‐Cultures for Functional Testing of Cancer Nanovaccines

open access: yesAdvanced Science, EarlyView.
Pancreatic ductal adenocarcinoma remains difficult to treat. We establish an organoid–immune co‐culture using patient‐derived organoids and matched T‐cells to assess cancer vaccines. A mesothelin‐targeted nanovaccine activates antigen‐specific T‐cells, increases IFN‐γ, and targets MSLN+ organoids.

Bio‐Based Wax Interfaces for Droplet Energy Harvesting at Fluoropolymer‐Like Output Levels

open access: yesAdvanced Science, EarlyView.
Replacing unsustainable fluorinated polymers in droplet‐based energy harvesters is usually limited by low power outputs, but carefully selected bio‐based polymers are capable of creating fluoropolymer‐like voltage outputs. Abstract Droplet impact and rebound on solid surfaces has emerged as a promising method for energy harvesting, typically ...

Frugivoría y dispersión de semillas de la palma Oenocarpus bataua (Arecaceae) en un bosque de los Andes colombianos Frugivory and seed dispersal Oenocarpus bataua palm (Arecaceae) in a forest from the Colombian Andes

open access: yesRevista de Biología Tropical, 2012
En zonas bajas tropicales, en bosques continuos y relativamente poco intervenidos, los frutos de la palma Oenocarpus bataua Mart., son consumidos por diversas especies de vertebrados, sin embargo, no hay estudios de dispersión de más largo plazo con esta

Palms are unique: clade‐level pattern of the leaf-height-seed strategy scheme

open access: yesFrontiers in Plant Science
IntroductionThe leaf-height-seed (LHS) plant ecology strategy scheme posits that functional traits such as leaf size, stem height and seed mass play a key role in life history of plants.
