Osteogenic effect of inflammatory macrophages loaded onto mineral bone substitute in subcutaneous implants [PDF]

Archives of Biological Sciences, 2015
We analyzed the influence of inflammatory macrophages on the osteogenic process in subcutaneous implants composed of mineral bone substitute. Thioglycollate-elicited peritoneal macrophages (TEPMs) were characterized as inflammatory.

A GmeIF2B5‐GmPRX4 Regulatory Axis Divergently Governs Drought‐Lignin and Salt‐Ion Homeostasis in Soybean

Plant Biotechnology Journal, EarlyView.
ABSTRACT Abiotic stresses severely constrain soybean productivity worldwide. Here we demonstrate that gmeif2b5 (eukaryotic initiation factors) mutants confer dual stress tolerance through coordinated mechanisms. Integrative RNA‐Seq and protein interaction analyses revealed that gmeif2b5 mutants increase lignin deposition to increase drought resilience ...

Superoxide and Hydrogen Peroxide Play Different Roles in the Nonhost Interaction of Barley and Wheat with Inappropriate formae speciales of Blumeria graminis

Molecular Plant-Microbe Interactions, 2004
Nonhost resistance of cereals to inappropriate formae speciales of Blumeria graminis is little understood. However, on the microscopic level, nonhost defense to B.

OsFeSOD3 Functions as an Enzymatic Component of the PEP Complex, Bifunctionally Regulating Chloroplastic ROS Metabolism and Chloroplast Biogenesis in Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Chloroplasts are essential organelles responsible for photosynthesis, providing energy and metabolic intermediates required for plant growth and productivity. Chloroplast development is highly sensitive to environmental stresses such as drought, and this sensitivity is closely associated with growth inhibition and yield reduction under stress ...

Leukocytes respiratory burst activity as indicator of innate immunity of pacu Piaractus mesopotamicus

Brazilian Journal of Biology
The present study evaluated the assay to quantify the respiratory burst activity of blood leukocytes of pacu as an indicator of the innate immune system, using the reduction of nitroblue tetrazolium (NBT) to formazan as a measure of the production of ...

The MdICE1/MdFAMA‐MdTYDC Transcriptional Module Confers Cold Tolerance by Regulating Dopamine Metabolism in Apple

Plant Biotechnology Journal, EarlyView.
ABSTRACT Low temperature is a critical abiotic stress that imposes major constraints on the sustainable development of the fruit tree industry. Although exogenous dopamine has been shown to enhance cold tolerance in plants, its molecular mechanisms in apple (Malus domestica) remain poorly understood.

OsMT2b Regulates Pollen Development and ROS Homeostasis in a Photoperiod‐Dependent Manner

Plant Biotechnology Journal, EarlyView.
ABSTRACT Reactive oxygen species (ROS) are signalling molecules that promote programmed cell death in animal and plant systems. However, their role in rice (Oryza sativa L.) anther development is unclear. In this study, we show that lower transcript levels of the metallothionein gene OsMT2b in japonica rice plants obtained by RNA interference (RNAi ...

Variant of X-Linked Chronic Granulomatous Disease Revealed by a Severe Burkholderia cepacia Invasive Infection in an Infant

Case Reports in Immunology, 2013
Chronic granulomatous disease (CGD) is a primary immunodeficiency characterized by increased susceptibility to bacteria and fungi since early in life, caused by mutations in any of the five genes coding for protein subunits in NADPH oxidase.

Stress Granule‐Associated ZmCTU2 Confers Thermotolerance in Maize via Coordinated Regulation of Proteostasis and ROS Homeostasis

Plant Biotechnology Journal, EarlyView.
ABSTRACT The escalating global temperatures and intensifying heat stress events pose significant threats to maize productivity worldwide. Uncovering key thermotolerance genes and their functional mechanisms is thus critical for developing climate‐resilient crops.
