Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

The Growth Curves with Non-Linear Models of in Mixed-Sex of Caucasian Pheasants (Phasianus Colchicus Colchicus) [PDF]

open access: yesBrazilian Journal of Poultry Science
The Caucasian pheasant (Phasianus colchicus colchicus) is a Phasianidae family poultry species that is an important animal-based protein source. This study aimed to estimate the growth traits of body weight (BW) in pheasants using Logistic (L), Gompertz (

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

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

open access: yesFEBS 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.

Mathematical modeling for digestible protein in animal feeds for tilapia

open access: yesRevista Brasileira de Zootecnia, 2012
The objective of this study was to formulate mathematical models to estimate digestible protein in some animal feeds for tilapia. Literature results of the proximate composition of crude protein, ether extract, and mineral matter, as well as digestible ...

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

open access: yesFEBS 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.

Parametrização das equações de Hargreaves & Samani e Angströn-Prescott para estimativa da radiação solar na região de Telêmaco Borba, estado do Paraná Parameterization of Hargreaves & Samani and Angstrom-Prescott equations to estimate solar radiation in the region of Telemaco Borba, Parana state, Brazil

open access: yesCiência Rural, 2013
A estimativa da radiação solar incidente (Rs) por equações matemáticas é útil quando não se dispõe de estações meteorológicas que a registrem. O objetivo do trabalho foi estimar, para os períodos anual, sazonal e mensal, o coeficiente empírico Krs da ...

A NOVEL METHODOLOGICAL APPROACH OF ESTIMATING URBAN POPULATION IN NIGERIA

open access: yesGeography, Environment, Sustainability, 2018
The primary source of population data in Nigeria is the census despite its inconsistency. Consequently, efforts made to estimate population from such census figures and sometimes vital registration system has proved inadequate because of diverse problems.

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS 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+.

Dynamic surface water fraction (DSWF): Global surface water fraction mapping at 10-meter spatial resolution with Sentinel-2 imagery in Google Earth Engine

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
Mapping surface water at high spatiotemporal resolution is critical for managing water resources and mitigating disasters. Current global surface water datasets are typically generated at a relatively coarse monthly temporal resolution and 30-meter ...
