Anharmonic transitions in nearly dry l-cysteine I [PDF]

Journal of Physics: Condensed Matter, 2012
Two special dynamical transitions of universal character have been recently observed in macromolecules at $T_{D}\sim 180 - 220$ K and $T^{*}\sim 100$ K. Despite their relevance, a complete understanding of the nature of these transitions and their consequences for the bio-activity of the macromolecule is still lacking.

Evaluate the Therapeutic Effect of Allicin (L-cysteine) on Clinical Presentation and Prognosis in Patients with COVID-19

European Journal of Translational Myology, 2021
The antiviral effectiveness of allicin (L-cysteine) has been shown by numerous studies in both levels of clinical and animals. The aim of this study was to evaluate the therapeutic effect of allicin (L-cysteine) on clinical presentation and prognosis. In

Cystinuria and cystinosis are usually related to L-cystine: is this really the case for cystinosis? A physicochemical investigation at micrometre and nanometre scale

Comptes Rendus. Chimie, 2021
Medical literature indicates clearly that cystinuria and cystinosis, two severe genetic pathologies, are related to the presence of abnormal L-cystine deposits.

Characteristic Changes in Korean Native Cattle Spermatozoa Frozen-Thawed with L-Cysteine and/or Catalase

Journal of Animal Reproduction and Biotechnology, 2014
The objective of this study was to evaluate the characteristics of Korean Native Cattle sperm frozen-thawed with L-cysteine and/or catalase. The semen from bulls was collected by the artificial vagina method, and Triladyl containing 20% egg-yolk and/or L-

Enhanced L-cysteine production by overexpressing potential L-cysteine exporter genes in an L-cysteine-producing recombinant strain of Corynebacterium glutamicum [PDF]

Bioscience, Biotechnology, and Biochemistry, 2019
ABSTRACT We identified L-cysteine exporter candidates of Corynebacterium glutamicum and investigated the effect of overexpression of the potential L-cysteine exporter genes on L-cysteine production in a recombinant strain of C. glutamicum. Overexpression of NCgl2566 and NCgl0580 resulted in enhanced L-cysteine production in an L-cysteine-

Slow-release L-cysteine capsule prevents gastric mucosa exposure to carcinogenic acetaldehyde : results of a randomised single-blinded, cross-over study of Helicobacter-associated atrophic gastritis [PDF]

, 2016
Introduction: Helicobacter-induced atrophic gastritis with a hypochlorhydric milieu is a risk factor for gastric cancer. Microbes colonising acid-free stomach oxidise ethanol to acetaldehyde, a recognised group 1 carcinogen.

Induction of Glutathione Synthesis Provides Cardioprotection Regulating NO, AMPK and PPARa Signaling in Ischemic Rat Hearts

Life, 2021
Glutathione (GSH) is essential for antioxidant defence, and its depletion is associated with tissue damage during cardiac ischemia-reperfusion (I/R). GSH is synthesized by the glutamate-cysteine ligase enzyme (GCL) from L-cysteine, which alternatively ...

Enhancement of thioredoxin/glutaredoxin-mediated L-cysteine synthesis from S-sulfocysteine increases L-cysteine production in Escherichia coli

Microbial Cell Factories, 2012
Background Escherichia coli has two L-cysteine biosynthetic pathways; one is synthesized from O-acetyl L-serine (OAS) and sulfate by L-cysteine synthase (CysK), and another is produced via S-sulfocysteine (SSC) from OAS and thiosulfate by SSC synthase ...

Biomineralized CdS quantum dot nanocrystals: optimizing synthesis conditions and improving functional properties by surface modification [PDF]

, 2016
An engineered strain of Stenotrophomonas maltophilia (SMCD1) is capable of the direct extracellular biomineralization of CdS quantum dot nanocrystals from buffered aqueous solution of cadmium acetate and l-cysteine without the addition of a chemically ...
