Enhancing Recovery Yield of Vegetable Oil Methyl Ester for Bioresin Production: A Comparison Study Using Acid Neutralization

ChemEngineering
Vegetable oil methyl ester has promising properties for bio-based resin production due to its higher degree of unsaturation. The initial low methyl ester yield from corn oil compared to soybean and canola oils requires further investigation of the ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Daniel Berthelot. Part II. Contribution to electrolytic solutions

Educación Química, 2018
Daniel Berthelot (1865-1927) used the electrical conductivity method to carry on fundamental research on the chemical equilibrium present in highly diluted electrolyte solutions, using the electrical conductivity method. In this way he was able to follow

TOXIN-ANTITOXIN REACTION WITHOUT NEUTRALIZATION [PDF]

Journal of Experimental Medicine, 1932
1. Collodion particles adsorb diphtheria or tetanus or botulinus toxins. These toxins are retained on the particles when washed but are at least in part released in the animal. 2. The adsorbed toxins are neutralized by adsorption of the corresponding antitoxins but are unaffected by other serums. 3.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

An Eco-Friendly Neutralization Process by Carbon Mineralization for Ca-Rich Alkaline Wastewater Generated from Concrete Sludge

Metals, 2017
Waste-concrete recycling processes using wet-based crushing methods inevitably generate a large amount of alkaline concrete sludge, as well as wastewater, which contains abundant Ca ions. The Ca-rich alkaline wastewater must then be neutralized for reuse

Inhibiting stearoyl‐CoA desaturase suppresses bone metastatic prostate cancer by modulating cellular stress, mTOR signaling, and DNA damage response

FEBS Letters, EarlyView.
Bone metastasis in prostate cancer (PCa) patients is a clinical hurdle due to the poor understanding of the supportive bone microenvironment. Here, we identify stearoyl‐CoA desaturase (SCD) as a tumor‐promoting enzyme and potential therapeutic target in bone metastatic PCa.

Assessment of the ability of SARS-CoV-2 strains of genetic variants B.1.1 and JN.1 to evade neutralizing antibodies from 2020 and 2023 convalescent patients

Инфекция и иммунитет
Introduction. The SARS-CoV-2 virus is a highly variable pathogen accounted for by random mutations leading to the emergence of new genetic variants. Natural selection of SARS-CoV-2 variants is, among other things, the result of population level immunity ...

Tuning the Supramolecular Structures of Metal-Free Porphyrin via Surfactant Assisted Self-Assembly to Enhance Photocatalytic Performance

Nanomaterials, 2019
Metal-free porphyrin with good planarity is beneficial to π−π stack interactions, which promotes electron coupling and the separation and transfer of photogenerated carriers.

Empirical modeling the ultrasound-assisted base-catalyzed sunflower oil methanolysis kinetics [PDF]

Chemical Industry and Chemical Engineering Quarterly, 2012
The ultrasound-assisted sunflower oil methanolysis catalyzed by KOH was studied to define a simple empirical kinetic model useful for reactor design without complex computation.
