l-Amino Acid Production by a Immobilized Double-Racemase Hydantoinase Process: Improvement and Comparison with a Free Protein System [PDF]

, 2017
Protein immobilization is proving to be an environmentally friendly strategy for manufacturing biochemicals at high yields and low production costs. This work describes the optimization of the so-called “double-racemase hydantoinase process,” a system of

Single Test‐Based Diagnosis and Subtyping of Pulmonary Hypertension Caused by Fibrosing Mediastinitis Using Plasma Metabolic Analysis

Advanced Science, EarlyView.
Pulmonary hypertension caused by fibrosing mediastinitis has a five‐year survival rate of just 56%. Current diagnostic approaches are complex for patients with mobility limitations and can lead to misdiagnoses due to their nonspecific clinical features.

Defining the Biologically Plausible Taxonomic Domain of Applicability of an Adverse Outcome Pathway: A Case Study Linking Nicotinic Acetylcholine Receptor Activation to Colony Death

Environmental Toxicology and Chemistry, Volume 42, Issue 1, Page 71-87, January 2023., 2023
Abstract For the majority of developed adverse outcome pathways (AOPs), the taxonomic domain of applicability (tDOA) is typically narrowly defined with a single or a handful of species. Defining the tDOA of an AOP is critical for use in regulatory decision‐making, particularly when considering protection of untested species.

Incidental Polymorphism, Non-Isomorphic and Isomorphic Substitution in Calcium-Valine Coordination Polymers

Crystals, 2015
Five coordination polymers with the stoichiometry CaX2(valine)2(H2O)2 (X = Cl, Br) were obtained from the corresponding calcium halides and either racemic and enantiopure valine.

The AV1 Constrained Directional Enhancement Filter (CDEF) [PDF]

arXiv, 2016
This paper presents the constrained directional enhancement filter designed for the AV1 royalty-free video codec. The in-loop filter is based on a non-linear low-pass filter and is designed for vectorization efficiency. It takes into account the direction of edges and patterns being filtered.

Pass-back chain extension expands multimodular assembly line biosynthesis. [PDF]

, 2020
Modular nonribosomal peptide synthetase (NRPS) and polyketide synthase (PKS) enzymatic assembly lines are large and dynamic protein machines that generally effect a linear sequence of catalytic cycles.

Biallelic mutations in valyl-tRNA synthetase gene VARS are associated with a progressive neurodevelopmental epileptic encephalopathy. [PDF]

, 2019
Aminoacyl-tRNA synthetases (ARSs) function to transfer amino acids to cognate tRNA molecules, which are required for protein translation. To date, biallelic mutations in 31 ARS genes are known to cause recessive, early-onset severe multi-organ diseases ...

5-Valine-oxytocin and 1-Deamino-5-valine-oxytocin [PDF]

Journal of Biological Chemistry, 1966
Abstract The paper reports the syntheses of 5-valine-oxytocin and 1-deamino-5-valine-oxytocin, analogues of oxytocin and 1-deamino-oxytocin which contain a valine residue in place of the asparagine residue in position 5. On assay for biological activity, 5-valine-oxytocin was found to possess approximately 0.3 unit per mg of oxytocic activity and 0.1 ...

Enhancing Plastic Decomposition in Mealworms (Tenebrio molitor): The Role of Nutritional Amino Acids and Water

Advanced Energy and Sustainability Research, EarlyView.
The decomposition of single‐use plastics by selected insects is often sustained or enhanced through the addition of natural supplements or feeds. Herein, the rationale behind these choices is demonstrated by examining the effects of selected amino acids and water as enhancers in the biodegradation of polystyrene by mealworms.
