Lianas reduce carbon accumulation and storage in tropical forests [PDF]

open access: yes, 2015
Tropical forests store vast quantities of carbon, account for a third of the carbon fixed by photosynthesis, and are a major sink in the global carbon cycle.

Temporal Trends in Janus Kinase Inhibitor (JAKi) Use Across Five European Countries: A DARWIN EU Network Study

open access: yesPharmacoepidemiology and Drug Safety, Volume 35, Issue 11, November 2026.
ABSTRACT Introduction Janus kinase inhibitors (JAKi) are increasingly used for autoimmune conditions despite existing safety concerns. This study aims to estimate the incidence of new JAKi use over time and characterise users in Europe to support future safety studies.

Assessing the Health Impacts of Contaminants on Green Turtles (Chelonia mydas) Along the Southern Coast of Brazil

open access: yesEnvironmental Toxicology, Volume 41, Issue 11, Page 1277-1288, November 2026.
ABSTRACT Chemical pollutants pose a significant threat to marine ecosystems. Among these contaminants are trace elements and polycyclic aromatic hydrocarbons (PAH). Green turtles can be employed to evaluate the oceans' health due to their coastal habitats and exposure to multiple threats.

Charting Cervical Spinal Cord Morphometry Across the Lifespan

open access: yesHuman Brain Mapping, Volume 47, Issue 15, October 15, 2026.
From large multi‐site lifespan data, we segment C1–C7 and derive morphometric measures (area, diameters, shape). Normative centile charts summarize population trajectories across age and sex and provide a practical scoring framework to quantify where an individual lies relative to expected variation.

Engineered Microvascular Model of the Blood–Brain–Tumor Barrier Reveals Endothelial Remodeling in Diffuse Midline Glioma

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 37, 9 October 2026.
We developed a patient‐derived, functional microfluidic model of the diffuse midline glioma (DMG) blood–brain–tumor barrier (BBTB) comprised of endothelial cells, astrocytes, pericytes, and tumor cells. The system forms perfusable microvasculature, reveals the BBTB retains vascular integrity, identifies DMG‐specific transcriptomic changes distinct from

Sex‐specific brain reserve and progression from mild cognitive impairment to Alzheimer's disease dementia

open access: yesAlzheimer's &Dementia, Volume 22, Issue 10, October 2026.
Abstract INTRODUCTION Sex differences exist in Alzheimer's disease (AD) treatment response, but the role of sex in disease development and progression remains unclear. METHODS We performed multimodal analyses of AD biomarker–positive individuals with mild cognitive impairment (MCI) and AD from the Alzheimer's Disease Neuroimaging Initiative (ADNI; MCI ...

Contribution of Lianas to Plant Area Index and Canopy Structure in A Panamanian Forest [PDF]

open access: yes, 2016
Lianas are an important component of tropical forests, where they reduce tree growth, fecundity, and survival. Competition for light from lianas may be intense; however, the amount of light that lianas intercept is poorly understood.

The Contribution of Lianas to Forest Ecology, Diversity, and Dynamics

open access: yes, 2015
Lianas are a common component of forests worldwide and they contribute to forest ecology, diversity, and dynamics. Lianas can have both positive and negative effects in forests.

Detection of the Hepatotoxins, Carboxyparquin and Parquin, in Cestrum, Sessea, and Vestia Species (Solanaceae)

open access: yesChemistry &Biodiversity, Volume 23, Issue 10, October 2026.
Several species within the tribe, Cestreae, are implicated in being hepatotoxic to livestock. Carboxyparquin and/or parquin are implicated as the toxic principles. Herbarium vouchers are useful resources to screen for the occurrence of these toxins in species of Cestrum, Sessea, and Vestia.
