Early Differentiation Signatures in Human Induced Pluripotent Stem Cells Determined by Non-Targeted Metabolomics Analysis

open access: yesMetabolites, 2023
Human induced pluripotent stem cells (hiPSCs) possess immense potential as a valuable source for the generation of a wide variety of human cells, yet monitoring the early cell differentiation towards a specific lineage remains challenging. In this study,

Pyruvate-Associated Acid Resistance in Bacteria [PDF]

open access: yesApplied and Environmental Microbiology, 2014
ABSTRACT Glucose confers acid resistance on exponentially growing bacteria by repressing formation of the cyclic AMP (cAMP)-cAMP receptor protein (CRP) complex and consequently activating acid resistance genes. Therefore, in a glucose-rich growth environment, bacteria are capable of resisting acidic stresses due to low levels of cAMP-CRP ...

Advancing design strategies in smart stimulus‐responsive liposomes for drug release and nanomedicine

open access: yesBMEMat, EarlyView.
Schematic illustration of stimulus‐responsive liposomes designed for controlled drug release and nanomedicine. The innermost circle represents different liposomal structures, including unilamellar, multilamellar, and multivesicular liposomes. The middle layer illustrates the responsive phospholipid components.

Identification of differential metabolites in liquid diet fermented with Bacillus subtilis using gas chromatography time of flight mass spectrometry

open access: yesAnimal Nutrition, 2016
Growth and health responses of pigs fed fermented liquid diet are not always consistent and causes for this issue are still not very clear. Metabolites produced at different fermentation time points should be one of the most important contributors ...

Rehabilitation Improves Mitochondrial Energetics in Progressive Multiple Sclerosis: The Significant Role of Robot-Assisted Gait Training and of the Personalized Intensity

open access: yesDiagnostics, 2020
Abnormal levels of pyruvate and lactate were reported in multiple sclerosis (MS). We studied the response of markers of mitochondrial function to rehabilitation in relation to type, intensity and endurance performance in severely disabled MS patients ...

Isoprene photooxidation : new insights into the production of acids and organic nitrates [PDF]

open access: yes, 2009
We describe a nearly explicit chemical mechanism for isoprene photooxidation guided by chamber studies that include time-resolved observation of an extensive suite of volatile compounds.

Astrocytes and neurons communicate via a monocarboxylic acid shuttle [PDF]

open access: yes, 2020
Since formulation of the Astrocyte-Neuron Lactate Shuttle (ANLS) hypothesis in 1994, the hypothesis has provoked criticism and debate. Our review does not criticise, but rather integrates experimental data characterizing proton-linked monocarboxylate ...

Nutritional Content, Phytochemical Composition, and Physicochemical Properties of Different Quinoa (Chenopodium quinoa Willd.) Seed Varieties

open access: yesCereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Quinoa (Chenopodium quinoa Willd.) is a pseudocereal with documented benefits for human health. The macronutrient composition and phytochemical content of the grain are known to vary depending on the variety and the growing location.

Resistance imparted by vitamin C, vitamin e and vitamin B12 to the acute hepatic glycogen change in rats caused by noise. [PDF]

open access: yes, 2006
The effects of vitamin C, vitamin E and vitamin B12 on the noise-induced acute change in hepatic glycogen content in rats were investigated. The exposure of rats to 95 dB and 110 dB of noise acutely reduced their hepatic glycogens.
