Reactive oxygen species act as signaling molecules to control root hair initiation and tip growth

open access: yesNew Phytologist, Volume 247, Issue 5, Page 2042-2048, September 2025.
Summary Root hairs (RHs) increase the surface area of roots, facilitating nutrient and water uptake and plant anchorage. RHs form from root epidermal cells and elongate by polar tip growth. Reactive oxygen species (ROS) have recently been implicated as important signals that drive RH formation and elongation using both genetic and imaging approaches ...

Updated insights into the molecular pathogenesis of canine atopic dermatitis

open access: yesVeterinary Dermatology, Volume 36, Issue 4, Page 375-384, August 2025.
Abstract Atopic dermatitis (AD) is a common and chronic inflammatory skin disease with frequent relapses. The genomics revolution has greatly contributed and revolutionised our knowledge of human AD; understanding the molecular skin fingerprint of AD and associated pathogenic immune pathways has led to preclinical assessments of several novel ...

Cutaneous epitheliotropic T‐cell lymphoma in a sugar glider (Petaurus breviceps)

open access: yesVeterinary Dermatology, Volume 36, Issue 2, Page 218-221, April 2025.
A 3‐year‐old male sugar glider presented with pruritus and alopecia primarily affecting the back and neck regions. Dermatologic diagnostics ruled out common causes. Skin biopsies revealed cutaneous epitheliotropic T‐cell lymphoma, a rare condition in sugar gliders. Despite treatment, the glider's condition worsened, leading to death.

Analysis of the immunomodulatory properties of mycobacterium cell wall fraction on the cytokine production of peripheral blood mononuclear cells of healthy dogs

open access: yesVeterinary Dermatology, Volume 35, Issue 6, Page 595-604, December 2024.
Background – Mycobacterium cell wall fraction (MCWF) is derived from nonpathogenic Mycobacterium phlei and is used as an immunomodulatory compound in clinical practice, yet its mode‐of‐action requires further research. Objective – To evaluate the host response to MCWF in canine peripheral blood mononuclear cells (PBMCs) by using enzyme‐linked ...

Local lobbying in single‐party authoritarian systems: Do institutions matter?

open access: yesReview of Policy Research, Volume 41, Issue 6, Page 921-940, November 2024.
Abstract Lobbying, and its role in the policy process, has been extensively studied in democratic states, but much less is known about similar practices in authoritarian political systems. Although a few studies have identified lobbying in China, most have focused on big businesses and national policy making, and some have argued that it is unaffected ...
