School size, student achievement, and the "power rating" of poverty: Substantive finding or statistical artifact?

open access: yesEducation Policy Analysis Archives, 2006
The proportion of variance in student achievement that is explained by student SES-"poverty's power rating," as some call it-tends to be lower among smaller schools than among larger schools.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Inferring Emotion from Facial Expressions in Social Contexts : A Role of Self-Construal?

open access: yesJournal of European Psychology Students, 2010
The study attempted to replicate the findings of Masuda and colleagues (2008), testing a modified hypothesis: when judging people’s emotions from facial expressions, interdependence-primed participants, in contrast to independence-primed participants ...

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

open access: yesMolecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Phenotypic and genotypic characterization of single circulating tumor cells in the follow‐up of high‐grade serous ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Single circulating tumor cells (sCTCs) from high‐grade serous ovarian cancer patients were enriched, imaged, and genomically profiled using WGA and NGS at different time points during treatment. sCTCs revealed enrichment of alterations in Chromosomes 2, 7, and 12 as well as persistent or emerging oncogenic CNAs, supporting sCTC identity.

Iron Storage in Friedreich’s Ataxia

open access: yesPediatric Neurology Briefs, 1999
To test the hypothesis that iron is increased in the cerebellum of patients with Friedreich’s ataxia (FA), a multigradient echo magnetic resonance sequence for the three-dimensional imaging of brain iron-induced contrast was used in 12 patients and 23 ...

Dammarenediol II enhances etoposide‐induced apoptosis by targeting O‐GlcNAc transferase and Akt/GSK3β/mTOR signaling in liver cancer

open access: yesMolecular Oncology, EarlyView.
Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...

Iodinated contrast-induced sialadenitis: a review of the literature and sonographic findings in a clinical case

open access: yesJournal of Ultrasonography, 2018
Swelling of the salivary glands, also known as iodide or iodine mumps, is a rare adverse reaction to administration of iodine, a component steadily present in current contrast media and in a variety of medications.

Effect of contrast on the perception of direction of a moving pattern [PDF]

open access: yes
A series of experiments examining the effect of contrast on the perception of moving plaids was performed to test the hypothesis that the human visual system determines the direction of a moving plaid in a two-staged process: decomposition into component

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...
