p13CMFA: Parsimonious 13C metabolic flux analysis
Deciphering the mechanisms of regulation of metabolic networks subjected to perturbations, including disease states and drug-induced stress, relies on tracing metabolic fluxes. One of the most informative data to predict ...
Evaluation of Hold-Up Volume Determination Methods and Markers in Hydrophilic Interaction Liquid Chromatograph
Common methods for hold-up time and volume determination in Reversed-Phase Liquid Chromatography (RPLC) have been tested for Hydrophilic Interaction Liquid Chromatography (HILIC). A zwitterionic ZIC-HILIC column has been ...
Brown adipose tissue bioenergetics: a new methodological approach
The rediscovery of brown adipose tissue (BAT) in humans and its capacity to oxidize fat and dissipate energy as heat has put the spotlight on its potential as a therapeutic target in the treatment of several metabolic ...
Neuroprotective effects of the multitarget agent AVCRI104P3 in brain of middle-aged mice
Molecular factors involved in neuroprotection are key in the design of novelmultitarget drugs in aging and neurodegeneration. AVCRI104P3 is a huprine derivative that exhibits potent inhibitory effects on human AChE, BuChE, ...
The secreted autotransporter toxin (Sat) does not act as a virulence factor in the probiotic Escherichia coli strain Nissle 1917
BACKGROUND: Escherichia coli Nissle 1917 (EcN) is a probiotic used in the treatment of intestinal diseases. Although it is considered safe, EcN is closely related to the uropathogenic E. coli strain CFT073 and contains ...
Prevalent sequences in the Human Genome Can Form Mini i-Motif Structures at Physiological pH
We report here the solution structure of several repetitive DNA sequences containing d(TCGTTCCGT) and related repeats. At physiological pH, these sequences fold into i-motif like quadruplexes in which every two repeats a ...
Metagenomics for the study of viruses in urban sewage as a tool for public health surveillance
The application of next-generation sequencing (NGS) techniques for the identification of viruses present in urban sewage has not been fully explored. This is partially due to a lack of reliable and sensitive protocols for ...
Genetics and Genomics of SOST: functional analysis of variants and genomic regulation in osteoblasts
SOST encodes the sclerostin protein, which acts as a key extracellular inhibitor of the canonical Wnt pathway in bone, playing a crucial role in skeletal development and bone homeostasis. The objective of this work was to ...
CAPTVRED: An automated pipeline for viral tracking and discovery from capture-based metagenomics samples.
Summary: Target Enrichment Sequencing or Capture-based metagenomics has emerged as an approach of interest for viral metagenomics in complex samples. However, these datasets are usually analyzed with standard downstream ...
Diurnal cortisol throughout pregnancy and its association with maternal depressive symptoms and birth outcomes
Background: Depression during pregnancy is a common complication that can negatively affect fetal health and birth outcomes. Cortisol is believed to be a key mediator of this association. Although pregnancy entails a natural ...
Evaluation of methods for the concentration and extraction of viruses from sewage in the context of metagenomic sequencing
Viral sewage metagenomics is a novel field of study used for surveillance, epidemiological studies, and evaluation of waste water treatment efficiency. In raw sewage human waste is mixed with household, industrial and ...
Pentafluorosulfanyl-containing Triclocarban Analogs with Potent Antimicrobial Activity
Concerns have been raised about the long-term accumulating effects of triclocarban, a polychlorinated diarylurea widely used as an antibacterial soap additive, in the environment and in human beings. Indeed, the Food and ...
Oleate Reverses Palmitate-induced Insulin Resistance and Inflammation in Skeletal Muscle Cells
Here we report that in skeletal muscle cells the contribution to insulin resistance and inflammation of two common dietary long-chain fatty acids depends on the channeling of these lipids to distinct cellular metabolic ...
Combined drug action of 2-phenylimidazo[2,1-b]benzothiazole derivatives on cancer cells according to their oncogenic molecular signatures
The development of targeted molecular therapies has provided remarkable advances into the treatment of human cancers. However, in most tumors the selective pressure triggered by anticancer agents encourages cancer cells ...
Induction of oxidative metabolism by the p38α/MK2 pathway
Adequate responses to environmental stresses are essential for cell survival. The regulation of cellular energetics that involves mitochondrial energy production and oxidative stress is central in the process of stress ...
Alternative access to functionalized 2,8-ethanonoradamantane derivatives
7a-(Methoxycarbonyl)-N-methyl-1,3a,5,6,7,7a-hexahydro-4H-1,4,6-(epiethane[1,1,2]triyl) indene-4,9-dicarboximide has been prepared through a modification of a previous synthetic sequence, in which the benzyloxymethyl hydroxyl ...
Elafibranor upregulates the EMT-inducer S100A4 via PPARbeta/delta
Elafibranor is a dual peroxisome proliferator-activated receptor (PPAR)α and β/δ agonist that has reached a phase III clinical trial for the treatment of metabolic dysfunction-associated steatotic liver disease (MASLD). ...
Can Förster Theory Describe Stereoselective Energy Transfer Dynamics in a Protein-Ligand Complex?
Förster resonance energy transfer (FRET) reactions involving ligands and aromatic amino acids can substantially impact the fluorescence properties of a protein-ligand complex, an impact intimately related to the corresponding ...
Enantioselective synthesis of lepadins A D from a phenylglycinol-derived hydroquinolone lactam
The marine alkaloids (-)-lepadins A-C and (+)-lepadin D, belonging to two diastereoisomeric series, were synthesized from an (R)-phenylglycinol-derived tricyclic lactam via a common cis-decahydroquinoline intermediate. ...
Enhancing hepatic fatty acid oxidation as a strategy for reversing metabolic disorders programmed by maternal undernutrition during gestation
Background/Aims: Moderate maternal calorie-restriction during gestation programmes offspring for a major propensity to develop metabolic alterations in adulthood. We aimed to assess whether increased hepatic fatty-acid ...
