Rates of Filtration and Ingestion of a Microalga by Philodina roseola (Rotifera: Bdelloidea)

open access: yesActa Biológica Colombiana, 2016
Rotifers play an important role in biogeochemical cycles and organic productivity of freshwater ecosystems due to their high metabolic rates. Information on filter feeding, their main process of energy acquisition, are relevant and still scarce for ...

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

open access: yesFEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

AAA+ protein unfoldases—the Moirai of the proteome

open access: yesFEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Cluster analysis of symptoms and assessment of caregiver reports in pediatric foreign bodies

open access: yesScientific Reports
Foreign body (FB) ingestion and aspiration are frequent causes of pediatric emergency room visits, with significant morbidity and mortality risks. This cross-sectional study analyzed 1,052 pediatric patients admitted for suspected FB events at a single ...

The effect of fructose and maltodextrin vs glucose and maltodextrin formulated sports beverages on mountain-bike race performance : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Sport and Exercise Science at Massey University, Wellington, New Zealand [PDF]

open access: yes, 2007
Background: Exogenous carbohydrate improves performance during prolonged high-intensity exercise. When ingested together, fructose and glucose polymers are oxidised at rates 1.5-1.7 higher than isocaloric glucose solutions.

Omnivory by the Small Cosmopolitan Hydromedusa Aglaura Hemistoma [PDF]

open access: yes, 2005
We investigated the feeding of the small hydromedusa, Aglaura hemistoma (bell diameter \u3c 4 mm), to determine if it occupies a trophic position similar to that of large medusae.
