Plasma cytokine concentrations in workers exposed to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)

open access: yesFrontiers in Oncology, 2012
ObjectivesFew epidemiological studies have studied the effect of 2,3,7,8-tetrachlorodibenzo-p dioxin (TCDD) on blood cytokine levels. In this study we investigated changes in plasma levels of a large panel of cytokines, chemokines and growth factors ...

Transcranial Color‐Coded Duplex Sonography in Large‐Vessel Vasculitis Compatible With Takayasu Arteritis Presenting Intracranial Involvement and Vertebrobasilar Dolichoectasia: A Case Report

open access: yesJournal of Clinical Ultrasound, Volume 54, Issue 7, Page 1710-1716, September 2026.
This case illustrates sequential intracranial occlusions in large‐vessel vasculitis compatible with Takayasu arteritis preserving perfusion through robust collateral pathways. Transcranial color‐coded duplex sonography identified characteristic blunted flow patterns and focal turbulence, underscoring its value in detecting hemodynamic compromise beyond

Rethinking Senescence Hallmarks in the Brain: Lessons From Peripheral Tissues and Challenges in Defining Neuronal Senescence

open access: yesAging Cell, Volume 25, Issue 9, September 2026.
Neuronal senescence‐like states arise from convergent intrinsic and disease‐associated stressors and are linked to persistent dysfunction, SASP‐like signaling, and altered glial interactions. Because no single marker is definitive in post‐mitotic neurons, multimarker and context‐dependent frameworks are required to define their role in ...

A Review of the Effects of Freshwater Habitat Quality on Aquatic & Semi‐Aquatic Turtles

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
This literature review aims to provide a comprehensive review of the relationship between freshwater turtles and their aquatic environments. We also highlight areas which have been over‐ or under‐studied and offer recommendations for future research. ABSTRACT Freshwater turtles and terrapins require an aquatic habitat as part of their natural ecology ...

Climate‐Action Driven Emission Changes of Unintentional Persistent Organic Pollutants From Global Copper Industry

open access: yesGlobal Challenges, Volume 10, Issue 8, August 2026.
Climate action profoundly reshapes global copper production by increasing output and altering the production technology mix. These changes also raise emissions of unintentional persistent organic pollutants (UPOPs) from the copper industry, revealing a hidden pollution trade‐off that should be addressed alongside decarbonization.
