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

New 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 ...

Modulation of Cytokine and Cytokine Receptor/Antagonist by Treatment with Doxycycline and Tetracycline in Patients with Dengue Fever

Journal of Immunology Research, Volume 2011, Issue 1, 2011., 2011
Dengue virus infection can lead to dengue fever (DF) or dengue hemorrhagic fever (DHF). Disease severity has been linked to an increase in various cytokine levels. In this study, we evaluated the effectiveness of doxycycline and tetracycline to modulate serum levels of IL‐6, IL‐1B, and TNF and cytokine receptor/receptor antagonist TNF‐R1 and IL‐1RA in ...

Salivary/Serum Progesterone Ratio Differs Between Menstrual Cycle Phases but Not Between Populations: Implications for Health, Reproductive, and Behavioral Research

American Journal of Human Biology, Volume 37, Issue 7, July 2025.
Scatterplot of paired measurements of PFree‐SAL (y‐axis, log scale) versus PTotal‐VEN (x‐axis, log scale) for each of our 36 Bolivian study participants. Dotted diagonals represent lines of constant uptake fraction (UF = PFree‐SAL/PTotal‐VEN) from 0.2% to 100%. The solid red line represents the linear regression model for luteal phase pairs (red dots),

Claw growth rates in a subset of adult, indoor, domestic cats (Felis catus)

Veterinary Dermatology, Volume 36, Issue 3, Page 362-367, June 2025.
Background – Keratinised tissues, such as nails and claws, accumulate hormones over time; the claws' hormone concentrations are being explored as potential biomarkers. Timelines for hormone deposition can be established if claw growth rates are known. Hormone concentration within cat claws has been recently evaluated, yet the growth rates of cat claws ...
