Elicitor effects on reactive oxygen species in liquid cultures of Penicillium chrysogenum [PDF]

, 2004
Activity of reactive oxygen species (ROS) was investigated in liquid cultures of Penicillium chrysogenum P2 supplemented with carbohydrates. Oligosaccharides lowered the ROS activity in all samples. The greatest effect occurred when oligosaccharides were

Granzymes in health and diseases: the good, the bad and the ugly

Frontiers in Immunology
Granzymes are a family of serine proteases, composed of five human members: GA, B, H, M and K. They were first discovered in the 1980s within cytotoxic granules released during NK cell- and T cell-mediated killing.

A long-term "memory" of HIF induction in response to chronic mild decreased oxygen after oxygen normalization [PDF]

, 2007
Background Endothelial dysfunction (ED) is functionally characterized by decreased vasorelaxation, increased thrombosis, increased inflammation, and altered angiogenic potential, has been intimately associated with the progression and severity of ...

Carbon nanotubes induce inflammation but decrease the production of reactive oxygen species in lung [PDF]

, 2010
With the rapid spread of carbon nanotubes (CNTs) applications, the respiratory toxicity of these compounds has attracted the attention of many scientists. Several studies have reported that after lung administration, CNTs could induce granuloma, fibrosis,

Oxygen Radicals and Reactive Oxygen Species in Reproduction

Experimental Biology and Medicine, 1991
Free radicals and reactive oxygen species play a number of significant and diverse roles in reproductive biology. In common with other biological systems, mechanisms have evolved to minimize the damaging effects that these highly reactive molecules can have on reproductive integrity.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Reactive Oxygen Species

, 2021
AbstractToday, many factors such as advancing technology, environmental pollution,radiation, contaminated water, pesticides, heavy metals, stress and oxygen metabolismin living cells inevitably cause the formation of free radicals in the human body.Free radicals are very reactive forms of oxygen that destroy the cells of the organism.This calls for ...
