Characterisation of 17th-18th centuries damask and gilt leathers by ATR-FTIR

Conservar Património, 2018
In this paper it is presented the characterisation of tannins used in the vegetable tanning of two types of European historic and decorative leathers from Portuguese collections, damask leathers and gilt leathers, dated from the 17th and 18th centuries ...

Disseminating “hidden” scientific collections: the medium and large-sized terrestrial mammals at the Museo di Anatomia Comparata “Giovanni Battista Grassi”, Roma, Italy [PDF]

Biodiversity Data Journal
The dissemination of specimen data in scientific collections is a crucial step in making them available to the scientific community. However, even today, especially in some countries, little or nothing is known about the contents of the naturalistic ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Gemme romane in Italia settentrionale. Collezioni, studi, rinvenimenti: una ricognizione

Pallas, 2010
In Northern Italy, numerous «historic» collections are known, gathered by XVIth-XIXth century collectors: they hold antique or «after the antique» gems bought in various places; they have a high cultural value but porvide no indication of their origin ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Sustaining Cultural Heritage at UNH [PDF]

, 2015
Building a new road? A cell phone tower? A pipeline? A new government building? Building anything with federal funds or on federal property requires that one must conduct a review of the impact of the project on tangible cultural resources, which ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Type specimens of Mollusca described by Col. George Montagu in the Royal Albert Memorial Museum & Art Gallery, Exeter and The Natural History Museum, London

Zoosystematics and Evolution, 2017
A complete list of new molluscan taxa introduced by Col. George Montagu (1753–1815) is presented. The available type material of these taxa are itemised and illustrated.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
