Understanding nitrate assimilation and its regulation in microalgae

Frontiers in Plant Science, 2015
Nitrate assimilation is a key process for nitrogen (N) acquisition in green microalgae. Among Chlorophyte algae, Chlamydomonas reinhardtii has resulted to be a good model system to unravel important facts of this process, and has provided important ...

Integrating Visible‐Light Photocatalysis and Enzymes for the Stereoselective Synthesis of Alcohols and Amines

Advanced Synthesis &Catalysis, EarlyView.
The integration between visible‐light photocatalysis and biocatalysis has the potential to greatly improve modern organic synthesis by combining the production of valuable synthetic intermediates under mild photochemical conditions with the high degree of stereoselectivity reached by enzymes. The review collects the recent efforts in the photoenzymatic

Emerging Therapeutic Strategies for Hearing Loss

Advanced Therapeutics, EarlyView.
Challenges still exist in treating hearing loss in cases of severe damage to hair cells or spiral ganglion neurons. Here, a schematic diagram of cochlear sensory hair cells and auditory nerves is presented. It is found that in normal Corti organs, hair cells have upright stereocilia at the top and auditory neurons at the base. Ototoxic drugs, noise, or

Microbial Reduction of Chromate in the presence of Nitrate by Three Nitrate Respiring Organisms.

Frontiers in Microbiology, 2012
A major challenge for the bioremediation of toxic metals is the co-occurrence of nitrate, as it can inhibit metal transformation. Geobacter metallireducens, Desulfovibrio desulfuricans, and Sulfurospirillum barnesii are three soil bacteria that can ...

Denitrification-derived nitric oxide modulates biofilm formation in Azospirillum brasilense [PDF]

, 2013
Azospirillum brasilense is a rhizobacterium that provides beneficial effects on plants when they colonize roots. The formation of complex bacterial communities known as biofilms begins with the interaction of planktonic cells with surfaces in response to

The roles of the nitrate reductase NarGHJI, the nitrite reductase NirBD and the response regulator GlnR in nitrate assimilation of Mycobacterium tuberculosis.

Microbiology, 2009
Mycobacterium tuberculosis can utilize various nutrients including nitrate as a source of nitrogen. Assimilation of nitrate requires the reduction of nitrate via nitrite to ammonium, which is then incorporated into metabolic pathways.

Bilirubin Targeting WNK1 to Alleviate NLRP3‐Mediated Neuroinflammation

Advanced Science, EarlyView.
At physiological concentrations, bilirubin binds to the kinase domain of WNK1, thereby augmenting its activity and facilitating the phosphorylation of downstream SPAK/OSR1. This phosphorylation inhibits KCC2 activity, leading to elevate intracellular chloride levels in neurons.

Synthesis of Silver Nanoparticles by a Bryophilous Rhizoctonia species

Nanomaterials and Nanotechnology, 2013
We demonstrate the synthesis of silver nanoparticles by a potentially benign species of bryophilous Rhizoctonia in two different media. The first medium supports fungal growth and the up‐regulation of nitrate reductase, while the second medium supports ...

Effect of Sodium Chloride on Nitrate, Ions Accumulation and Nitrate Reductase Activity in Two Rootstocks of Almond [PDF]

Zīst/shināsī-i Giyāhī-i Īrān, 2019
Limited data published about the effects of salinity on nitrogen assimilation of fruit trees such as almond. A greenhouse experiment was conducted to study the effect of sodium chloride (0, 75 and 150 mM NaCl) on nitrate reductase activity, accumulation ...
