A search for mid-IR bands of amino acids in the Perseus Molecular Cloud [PDF]

arXiv, 2021
Amino acids are building-blocks of proteins, basic constituents of all organisms and essential to life on Earth. They are present in carbonaceous chondrite meteorites and comets, but their origin is still unknown. Formation of amino acids in the interstellar medium is posible via specific gas-phase reactions in dark clouds, however sensitive ...

Efficient Generation of Megakaryocyte Progenitors and Platelets From HSPCs via JAK2/STAT3 Signaling

Advanced Science, EarlyView.
This research presents a novel strategy employing the VGM cocktail, which combines HES7 overexpression with HDAC inhibitor and GABA, to enhance platelet production from hematopoietic stem and progenitor cells by promoting megakaryocyte progenitor (MkP) generation.

Inhibitory gamma-aminobutyric acidergic neurons in the anterior cingulate cortex participate in the comorbidity of pain and emotion

Neural Regeneration Research
Pain is often comorbid with emotional disorders such as anxiety and depression. Hyperexcitability of the anterior cingulate cortex has been implicated in pain and pain-related negative emotions that arise from impairments in inhibitory gamma-aminobutyric

GABAergic signaling linked to autophagy enhances host protection against intracellular bacterial infections

Nature Communications, 2018
Gamma-aminobutyric acid (GABA) is a major inhibitory neurotransmitter in neuronal systems, but the potential role for such neurotransmitters on the immune system are emerging.

Temporal coding at the immature depolarizing GABAergic synapse

Frontiers in Cellular Neuroscience, 2010
In the developing hippocampus, GABA exerts depolarizing and excitatory actions and contributes to the generation of neuronal network driven Giant Depolarizing Potentials (GDPs).

Acid zeta function and ajoint acid zeta function [PDF]

arXiv, 2010
In this paper we set up the theory of acid zeta function and ajoint acid zeta function, based on the theory, we point out a reason to doubt the truth of the Riemann hypothesis and also as a consequence, we give out some new RH equivalences.

Wireless In Situ Catalytic Electron Signaling‐Mediated Transcriptomic Reprogramming for Neuron Regeneration via Adaptable Antennas

Advanced Science, EarlyView.
A wireless‐charging sustained oxygen release from conductive microgels (SOCO) served as an antenna and an on‐demand O2 release for nerve regeneration is developed. Introducing “electromagnetic messenger”, using external alternating magnetic field (AMF) to enhance catalytic oxygen release and electrical stimulation to promote the reconstruction of blood

Is Amino-Acid Homochirality Due To Asymmetric Photolysis In Space? [PDF]

arXiv, 1999
Amino acids occurring in proteins are, with rare exceptions, exclusively of the L-configuration. Among the many scenarios put forward to explain the origin of this chiral homogeneity (i.e., homochirality), one involves the asymmetric photolysis of amino acids present in space, triggered by circularly polarized UV radiation.

Benefit from Biomass Boiler Emissions to Increase Greenhouse CO2 Levels for Optimal Growth and Yield in Tomato, Cucumber, and Strawberry

Advanced Energy and Sustainability Research, EarlyView.
Using CO2‐rich polluting gases in greenhouse plant cultivation has proven to be a promising technique for stimulating plants while reducing emissions to the atmosphere. The use of an experimental biofilter proves to be effective in retaining most of the toxic particles. The alteration of physiological and metabolic parameters shows an adaptation of the

Are Strong Bronsted Acids Necessarily Strong Lewis Acids? [PDF]

arXiv, 2006
The Broensted and Lowry acid base theory is based on the capacity of proton donation or acceptance (in the presence or absence of a solvent) whereas the Lewis acid base theory is based on the propensity of electron pair acceptance or donation. We explore through DFT calculation the obvious question whether these two theories are in conformity with each
