Roman lamps discovered at Histria, in the Acropolis Centre‐South Sector (2013 and 2015)

open access: yesMateriale și Cercetări Arheologice, 2016
Even if it represents an important ceramic category, given the quantity of material discovered during archaeological excavations, as well as the chronological information they offer, lamps have not drawn enough the attention of the specialists.

Protocol for quantifying miRNA trafficking across the endosomal membrane

open access: yesFEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

Identification and characterisation of calcitonin receptor isoforms expressed in glioblastoma derived glioma stem and U‐87 MG cells

open access: yesFEBS Open Bio, EarlyView.
Glioblastoma cells express calcitonin receptor variants (CT receptor isoforms) that may help them survive stress. Using qPCR, transcript‐specific long‐read nanopore sequencing, immunofluorescence co‐localisation and comparative sequence analysis, this study identifies a novel alternatively spliced CALCR transcript that encodes the CTb receptor isoform ...

Language Contact and Semantic Development in Late Medieval English

open access: yes
The multilingual context of medieval Britain has been a focus of historical linguistic scholarship for some time, but Middle English has often been examined in isolation. This book analyzes a large dataset of English vocabulary from the late Middle Ages,

Comparative assessment of crystallographic and cryo‐EM models in the Protein Data Bank

open access: yesFEBS Open Bio, EarlyView.
Raw data obtained by X‐ray crystallography or cryo‐EM result in experimental maps, ultimately fitted by atomic models. Although the physical principles are different, the final results can be viewed, compared, and evaluated in the same way. With cryogenic electron microscopy (cryo‐EM) on track to surpass X‐ray crystallography as the preferred method ...

Epigraphic Evidence from the Dakhleh Oasis in the Late Period [PDF]

open access: yes, 2012
Until the 1990s, no information existed on the history of the Dakhleh Oasis during the Late Period. There were, in fact, some archaeological remains from this period that had come to light in the cemetery of 'Ain Tirghi, together with dated skeletal ...

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

open access: yesFEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Effects of dietary oyster peptide supplement on litter performance, immunological response of sows and growth performance of piglets

open access: yesFrontiers in Veterinary Science
IntroductionAnimal breeding and reproduction techniques has led to an increase in the number of offspring of sows. However, weak piglets and low survival rate of piglets occurs frequently.

BCG vaccination potentiates oxidative phosphorylation in neonatal myeloid‐derived suppressor cells

open access: yesFEBS Open Bio, EarlyView.
BCG vaccination enhances oxidative phosphorylation in neonatal MDSCs, impairing their immunosuppressive function. It upregulates electron transport chain genes and mitochondrial activity, increasing ATP and oxygen consumption. Pharmacological OXPHOS inhibition partially restores suppressive capacity, confirming causality.

Characterisation of seven longer period eclipsing binary systems

open access: yes
We report a joint analysis of TESS photometry and minerva-Australis spectroscopic observations for seven long-period eclipsing binary systems with F- and early-G-type dwarf primaries: TIC 37606218, TIC 73723286, TIC 172462064, TIC 220567625, TIC ...
