Higher Complement C4 Gene Copy Number Constitutes a Shared Genetic Risk Factor for Giant Cell Arteritis and IgA Vasculitis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Low copy number (CN) of complement C4 isoforms and high CN of retroviral HERV‐K elements are known risk factors for many immune‐mediated inflammatory diseases (IMIDs), often showing sex‐biased effects. Here, we assessed whether CN variation within the C4 gene contributes to giant cell arteritis (GCA) and IgA vasculitis (IgAV), two complex ...

Scientific collaboration in data‐intensive research networks: PhD fellows' expectations and early experiences

open access: yesJournal of the Association for Information Science and Technology, EarlyView.
Abstract Collaboration has become important at all stages of research careers. In data‐intensive research fields such as wind energy, many PhD fellows are socialized to such collaboration in networks that train a cohort of PhD fellows. Based on interviews with 23 PhD fellows in four wind‐energy training networks, we investigate their expectations and ...

Synergetic Combination of Carbon Xerogels, Graphene Oxide and nano‐ZnO for Aqueous and Organic Supercapacitors

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
This work proposes the synthesis of carbon‐based nanostructured materials obtained using ZnO as both nanos‐ template and catalysts simultaneously. During the synthesis, GO was used as a stabiliser, preventing the collapse of the 3D structure and improving its properties in terms of capacitance and surface area.

Recessed Microelectrodes as a Platform to Investigate the Intrinsic Redox Process of Prussian Blue Analogs for Energy Storage Application

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
A microelectrochemical analytical tool is proposed for the accelerated evaluation of the intrinsic electrochemical performance of Prussian‐blue analogues as solid active materials in Na+‐based batteries. By confining the solid active material inside a recessed microelectrode, accelerated voltammetric and galvanostatic cycling at high C‐rate become ...

Real‐Time Biomass Estimation in High‐Density Yeast Fermentations Using Soft Sensor Modeling

open access: yesBiotechnology and Bioengineering, EarlyView.
Accurate biomass measurements, both offline and online, are essential to improve prediction and control in yeast fermentation. This study develops regression‐based predictive models to correlate offline measurements (Dry Cell Weight and OD600 from a spectrophotometer) with online OD860 probe signals to provide accurate real‐time biomass estimations and

Oocyte–cumulus cell interaction: a key factor in early embryo development

open access: yesBiological Reviews, EarlyView.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.
