Clinical profile and management of a Spanish single-center retrospective cohort of patients with post-chikungunya associated complications

open access: yesTravel Medicine and Infectious Disease
Background: This study aims to describe post-chikungunya complications chronically developed cases in returning travelers from some epidemic/endemic regions, and the variables that are associated with the progression of acute or subacute cases to the ...

Electrical Resistivity Structure and Helium Isotopes around Naruko Volcano, Northeastern Japan and Its Implication for the Distribution of Crustal Magma

open access: yesInternational Journal of Geophysics, 2010
The two-dimensional electrical resistivity structure beneath Naruko volcano was determined using magnetotelluric soundings. The resulting model shows that a prominent conductor exists through the middle crust to the uppermost mantle beneath the volcano ...

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.

Educational Isolation: A challenge for schools in England [PDF]

open access: yes, 2019
Educational isolation is complex, grounded in location, situated in access to resources and results in reduced agency for schools. 'Educational Isolation: a challenge for schools in England' aims to provide an understanding of this complexity through ...

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.

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+.

Tetracycline-Regulated Expression of VEGF-A in Beta Cells Induces Angiogenesis: Improvement of Engraftment following Transplantation

open access: yesCell Transplantation, 2006
Early revascularization of pancreatic islet cells after transplantation is crucial for engraftment, and it has been suggested that vascular endothelial growth factor-A (VEGF-A) plays a significant role in this process.

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

open access: yesFEBS 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.

Principals' Perceptions of Isolation and Contributing Factors: A Mixed Methods Analysis [PDF]

open access: yes
Principals’ perceived isolation has been empirically associated with factors such as lower self-efficacy, job dissatisfaction, and burnout and a strong predictor of a principal's intentions to leave the profession.

Near-Fault Earthquake Ground Motion and Seismic Isolation Design

open access: yes, 2023
Seismic isolation is one of the most reliable passive structural control techniques with adequately established standards for the earthquake protection of structures from earthquakes.
