Light cone in a quantum spacetime

open access: yesPhysics Letters B, 2018
Noncommutative spacetimes are a proposed effective description of the low-energy regime of Quantum Gravity. Defining the microcausality relations of a scalar quantum field theory on the κ-Minkowski noncommutative spacetime allows us to define for the ...

Extended noncommutative Minkowski spacetimes and hybrid gauge symmetries

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
We study the Lie bialgebra structures that can be built on the one-dimensional central extension of the Poincaré and (A)dS algebras in (1 + 1) dimensions.

Physical constraints on quantum deformations of spacetime symmetries

open access: yesNuclear Physics B, 2018
In this work we study the deformations into Lie bialgebras of the three relativistic Lie algebras: de Sitter, Anti-de Sitter and Poincaré, which describe the symmetries of the three maximally symmetric spacetimes. These algebras represent the centerpiece

Association Analysis of Rare CNTN5 Variants With Autism Spectrum Disorder in a Japanese Population. [PDF]

open access: yesNeuropsychopharmacol Rep
We investigated the role of rare CNTN5 variants in ASD susceptibility by performing resequencing, genotyping, and association analysis in a Japanese population. Out of three identified CNTN5 rare putatively damaging variants, we found a nominally significant association between the I227 variant and ASD in 614 patients with ASD and 61 058 healthy ...

Proteomic diversification of spermatostyles among six species of whirligig beetles. [PDF]

open access: yesMol Reprod Dev
Whirligig beetle sperm travel cooperatively through the female reproductive tract attached to a spermatostyle, a poorly studied rod‐like structure. Proteome characterization revealed that spermatostyles are comprised of a restricted set of proteases and possess catalytic activity.

S‐adenosylmethionine and nicotinamide riboside therapy in Arts syndrome: A case report and literature review

open access: yesJIMD Reports, Volume 64, Issue 6, Page 417-423, November 2023., 2023
Abstract Phospho‐ribosyl‐pyrophosphate synthetase 1 (PRPS1) deficiency is secondary to loss of function variants in PRPS1. This enzyme generates phospho‐ribosyl‐pyrophosphate (PRPP), which is utilized in the synthesis of purines, nicotinamide adenine dinucleotide (NAD), and NAD phosphate (NADP), among other metabolic pathways.

Ready Biodegradability study and insights with ultra‐high‐performance liquid chromatograph coupled to a quadrupole time of flight of a Metformin‐based drug and of Metarecod, a natural substance‐based medical device

open access: yesJournal of Mass Spectrometry, Volume 58, Issue 10, October 2023., 2023
Abstract Drugs are indispensable products with incontrovertible benefits to human health and lifestyle. However, due to their overuse and improper disposal, unwanted residues of active pharmaceutical ingredients (APIs) have been found in different compartments of the environment and now are considered as contaminants of emerging concern (CECs ...

Contactin‐6‐deficient male mice exhibit the abnormal function of the accessory olfactory system and impaired reproductive behavior

open access: yesBrain and Behavior, Volume 13, Issue 4, April 2023., 2023
Abstract Introduction Contactin‐6 (CNTN6), also known as NB‐3, is a neural recognition molecule and a member of the contactin subgroup of the immunoglobulin superfamily. Gene encoding CNTN6 is expressed in many regions of the neural system, including the accessory olfactory bulb (AOB) in mice.

3q29 microduplication syndrome: New evidence for the refinement of the critical region

open access: yesMolecular Genetics &Genomic Medicine, Volume 11, Issue 4, April 2023., 2023
Pedigree for the family analysed in this study including the identified 3q29 microduplication variant. Abstract Background The 3q29 microduplication syndrome is a rare genomic disorder characterized by an extremely variable neurodevelopmental phenotype usually involving a genomic region ranging from 1.6 to 1.76 Mb.
