Heat‐evolved coral photosymbionts exhibit dampened stress responses across distinct physiological contexts

New Phytologist, EarlyView.
Summary Experimental evolution under elevated temperatures has generated heat‐evolved (HE) strains of Symbiodiniaceae that enhance coral bleaching tolerance. However, the biomolecular mechanisms underlying this resilience remain poorly understood. We conducted a laboratory heat‐stress experiment and applied synchrotron‐based Fourier transform infrared (

Beyond Deterministic Fetal Programming: Intrauterine Exposures and the Multifactorial Origins of Adiposity

Obesity Reviews, EarlyView.
ABSTRACT Excess adiposity is not a recently developed problem but has existed since at least the upper Paleolithic, allowing evolutionary selection pressures to adapt the physiology of the pregnant woman and the feto‐placental unit for maternal and fetal protection.

The CaM1‐CBP60b‐MYB77 Transcriptional Cascade Regulates K+ Homeostasis and Salt Tolerance in Barley

Plant Biotechnology Journal, EarlyView.
ABSTRACT Soil salinity is a major abiotic stress that threatens global crop productivity. Calcium (Ca2+) is a pivotal second messenger in plant stress signalling, but how Ca2+ sensors such as calmodulin (CaM) transcriptionally control ion homeostasis and salt tolerance remains largely understood in crops.

Engineered surface strategies to manage dental implant‐related infections

Periodontology 2000, EarlyView.
Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.

Surface Modification with Micro-arc Oxidation

2019
Micro-arc oxidation (MAO) is one of the methods of surface modification of metal substrates and is a relatively simple procedure. The MAO surface is suitable for biomaterials because of its rough complex geometry and the ability to incorporate various ions.

Ceramic oxide coating formed on beryllium by micro-arc oxidation

Corrosion Science, 2017
Abstract Beryllium was oxidized at a current density of 10 mA cm −2 in a 0.5 M Na 2 CO 3 (pH = 11.2) electrolyte to understand the micro-arc oxidation (MAO) process. Different oxidation stages were investigated by analysing the voltage–time responses and coating morphology.

Formation and bioactivity of HA nanorods on micro-arc oxidized zirconium

Materials Science and Engineering: C, 2014
A microporous and CaO partially stabilized zirconia (Ca-PSZ) coating covered with hydroxyapatite (HA) nanorods is fabricated on Zr substrate by a hybrid approach of micro-arc oxidation (MAO) and hydrothermal treatment (HT). The effect of P ions in HT solution on the density and morphology of HA was investigated; the hydrophilicity and apatite-forming ...

Bioactivity and osteoblast response of the micro‐arc oxidized zirconia films

Journal of Biomedical Materials Research Part A, 2008
AbstractZirconia films containing Ca and P were prepared by micro‐arc oxidation (MAO) of zirconium. The microstructure, in vitro bioactivity, and primary osteoblast response of the films were investigated as a function of the applied voltages in the range of 400–500 V.

Synthesis of bioactive ceramic on the titanium substrate by micro‐arc oxidation

Journal of Biomedical Materials Research Part A, 2008
AbstractBioactive ceramic films on titanium substrate are prepared successfully by micro‐arc oxidation in electrolyte solution containing NaOH only. The coatings are prepared by micro‐arc oxidation at various applied current densities (200–400 mA/cm2) and in NaOH electrolyte with different concentrations. The XRD shows that they are composed of rutile,
