Influence of Pyruvic Acid and UV Radiation on the Morphology of Silica-carbonate Crystalline Biomorphs

Crystals, 2019
In this work we report the effect of introducing pyruvic acid (PA) in the growing process of silica-carbonate biomorphs. Gas-diffusion and single-phase methods were performed, and different concentrations of pyruvic acid were tested.

Gas-Phase Photolysis of Pyruvic Acid: The Effect of Pressure on Reaction Rates and Products.

Journal of Physical Chemistry A, 2016
In this work, we investigate the impact of pressure and oxygen on the kinetics of and products from the gas-phase photolysis of pyruvic acid. The results reveal a decrease in the photolysis quantum yield as pressure of air or nitrogen is increased, a ...

Experiments on the carboxylase of pea roots [PDF]

, 1941
It is known that vitamin B1 is a growth factor for numerous bacteria and fungi including the yeasts (see the summary in Koser and Saunders (1938)). It has also been demonstrated that vitamin B1 is essential for the growth of the isolated roots of higher ...

Biocatalysis as Useful Tool in Asymmetric Synthesis: An Assessment of Recently Granted Patents (2014–2019) [PDF]

, 2019
The broad interdisciplinary nature of biocatalysis fosters innovation, as different technical fields are interconnected and synergized. A way to depict that innovation is by conducting a survey on patent activities.

Oral Administration of Trichosanthes Kirilowii Fruit Extract Ameliorates Airway Inflammation and Suppresses Th2 Cell Activities in Ovalbumin‐Sensitized Mice

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Trichosanthes kirilowii is a plant used in traditional Chinese medicine. Its fruits, seeds, and roots can all be used medicinally. The fruit of T. kirilowii has a moistening effect on the lung for arresting cough. However, there is no scientific research to prove that the fruit of T. kirilowii can improve asthma. Herein, we evaluated whether T.

Krebs Cycle Intermediates Protective against Oxidative Stress by Modulating the Level of Reactive Oxygen Species in Neuronal HT22 Cells

Antioxidants, 2017
Krebs cycle intermediates (KCIs) are reported to function as energy substrates in mitochondria and to exert antioxidants effects on the brain. The present study was designed to identify which KCIs are effective neuroprotective compounds against oxidative

Immunometabolism is a key factor for the persistent spontaneous elite control of HIV-1 infection [PDF]

, 2019
Approximately 25% of elite controllers (ECs) lose their virological control by mechanisms that are only partially known. Recently, immunovirological and proteomic factors have been associated to the loss of spontaneous control. Our aim was to perform a

Contrasting functional responses of benthic and hyporheic stream biofilms to light availability and macronutrient stoichiometry

Limnology and Oceanography, EarlyView.
Abstract Nutrient dynamics in headwater streams are governed by benthic and hyporheic biofilms, with carbon (C) : nitrogen (N) : phosphorus (P) ratios driving the heterotrophic microbial biofilm development through nutrient limitation. Furthermore, heterotrophic responses to changes in C : N : P ratios are probably modulated by autotrophic responses to

Radial multi‐echo bSSFP and IDEAL chemical shift separation in k‐space for high‐speed 3D hyperpolarized 13C metabolic MRI

Magnetic Resonance in Medicine, EarlyView.
Purpose Hyperpolarized (HP) carbon‐13 (13C) MRSI provides real‐time information about metabolic processes but lacks high temporal and spatial resolution. This study introduces a multi‐echo–balanced steady‐state free precession (ME‐bSSFP) method with a 3D radial readout trajectory in a spiral phyllotaxis pattern as a method for non‐Cartesian HP 13C MRSI

Effects of HMG CoA reductase (HMGCR) deficiency on skeletal muscle development

The FEBS Journal, EarlyView.
Three skeletal muscle diseases are linked to HMGCR, a key enzyme in cholesterol synthesis. These diseases include a muscular dystrophy associated with pathogenic variants in the HMGCR gene, statin‐associated myopathy, and autoimmune anti‐HMGCR myopathy.
