Human colon organoid differentiation from induced pluripotent stem cells using an improved method
FEBS Letters, Volume 599, Issue 6, Page 912-924, March 2025.We compared established protocols to differentiate induced pluripotent stem cells into colon organoids and found that activation of bone morphogenetic protein 2 signaling induced gene expression of colon‐specific markers. Adenovirus‐mediated transduction of the transcription factors HOXD13 or SATB2 further enhanced colonic gene expression, suggesting ...

Investigating the spectral age problem with powerful radio galaxies [PDF]
, 2019 The 'spectral age problem' is our systematic inability to reconcile the maximum cooling time of radiating electrons in the lobes of a radio galaxy with its age as modelled by the dynamical evolution of the lobes. While there are known uncertainties in the models that produce both age estimates, `spectral' ages are commonly underestimated relative to ...

Coupled Hydro-Mechanical Aging Of Short Flax Fiber Reinforced Composites [PDF]
Polymer Degradation and Stability, Elsevier, 2016, 130, pp.300 -
306, 2018 One of the challenges in the widespread use of biocomposites for engineering applications is the influence of environmental conditions on their mechanical properties, particularly for a combination of aging factors such as temperature, moisture, and mechanical stresses.

Journal of Autism and Developmental Disorders, 2016 Clinical initiatives have aimed to reduce the age at ASD diagnosis in the UK. This study investigated whether the median age at diagnosis in childhood has reduced in recent years, and identified the factors associated with earlier diagnosis in the UK ...

FEBS Letters, Volume 599, Issue 7, Page 1055-1074, April 2025.Hermansky‐Pudlak syndrome type 1 (HPS‐1) is a rare, autosomal recessive disorder with poorly understood renal involvement. Urinary extracellular vesicle (uEV) proteomics and a novel Hps1 mouse model reveal mitochondrial abnormalities and lipid accumulation in HPS‐1 kidney proximal tubule cells. Serum ApoA1 correlates with kidney function in our patient

Introduction and reconciliation of the ROS and aging paradoxes [PDF]
arXiv, 2017 This paper suggests that aging is influenced synthetically by pro-aging factors such as ROS and anti-aging factors such as protective responses. The anti-aging effect may be side effects of retrograde responses motivated against adverse circumstances. ROS may be more closely correlated with metabolism rather than aging.

The Relationship between Accretion Disc Age and Stellar Age and its Consequences for Proto-Stellar Discs [PDF]
, 2011 We show that for young stars which are still accreting and for which measurements of stellar age, disc mass and accretion rate are available, nominal disc age (Disc Age = Disc Mass / Accretion Rate) is approximately equal to the stellar age, at least within the considerable observational scatter.

FEBS Letters, Volume 599, Issue 7, Page 1075-1085, April 2025.We describe a novel set of Epac‐based FRET‐FLIM biosensors with improved fully cytosolic distribution, achieved without compromising the state‐of‐the‐art performance of our original designs, for detecting cAMP dynamics in real time in live cells with high precision and reliability.

Detection of risk factors for obesity in early childhood with quantile regression methods for longitudinal data [PDF]
, 2008 This article compares and discusses three different statistical methods for investigating risk factors for overweight and obesity in early childhood by means of the LISA study, a recent German birth cohort study with 3097 children.
