Evergreened drugs or evergreened profits?

Journal of Evaluation in Clinical Practice, 2022
AbstractBackground: Branded drugs contribute disproportionately to high prescription drug spending. Pharmaceutical companies utilize patent extension “evergreening” techniques that contribute to high drug costs. Aims: This article describes various patent extension techniques and analyzes the tactic of combining generic drugs with branded drugs, using ...

Phylogenomic insights into the origin and evolutionary history of evergreen broadleaved forests in East Asia under Cenozoic climate change

Molecular Ecology, 2023
The evergreen versus deciduous leaf habit is an important functional trait for adaptation of forest trees and has been hypothesized to be related to the evolutionary processes of the component species under paleoclimatic change, and potentially reflected

A cost-benefit analysis of leaf carbon economy with consideration of seasonal changes in leaf traits for sympatric deciduous and evergreen congeners - implications for their coexistence.

New Phytologist, 2022
Deciduous and evergreen species, which have evolved repeatedly across different clades, can coexist in a given environment despite substantial differences in their leaf traits.

Evergreening

Journal of Financial Economics, 2023
We develop a simple model of concentrated lending where lenders have incentives for evergreening loans by offering better terms to firms that are close to default. We detect such lending behavior using loan-level supervisory data for the United States.

High ecosystem stability of evergreen broadleaf forests under severe droughts

Global Change Biology, 2019
Global increase in drought occurrences threatens the stability of terrestrial ecosystem functioning. Evergreen broadleaf forests (EBFs) keep leaves throughout the year, and therefore could experience higher drought risks than other biomes.

Effects of evergreen trees on landscape preference and perceived restorativeness across seasons

, 2020
Season is an important factor influencing preference and psychological restoration, especially in temperate regions. Evergreen plants can mediate landscape changes across seasons and increase greenness when deciduous trees are leafless. However, what are

Differential determinants of growth rates in subtropical evergreen and deciduous juvenile trees: Carbon gain, hydraulics and nutrient use efficiencies.

Tree Physiology, 2020
Growth rate varies across plant species and represents an important ecological strategy for competition, resource use and fitness. However, empirical studies often show a low predictability of functional traits to tree growth.

Canopy photosynthetic capacity drives contrasting age dynamics of resource use efficiencies between mature temperate evergreen and deciduous forests

Global Change Biology, 2020
Forest resource use efficiencies (RUEs) can vary with tree age, but the nature of these trends and their underlying mechanisms are not well understood. Understanding the age dynamics of forest RUEs and their drivers is vital for assessing the trade‐offs ...
