Helioseismic Tests of Radiative Opacities [PDF]

open access: yes, 2002
During the past fifteen years, thousands of solar acoustic oscillation modes have been measured to remarkable precision, in many cases to within 0.01%.

The Role of Opacities in Stellar Pulsation [PDF]

open access: yes, 2018
We examine the role of opacities in stellar pulsation with reference to Cepheids and RR Lyraes, and examine the effect of augmented opacities on the theoretical pulsation light curves in key temperature ranges.

p190A/ARHGAP35 and p190B/ARHGAP5 proteins in endometrial cancer: a novel cancer‐relevant paralog interplay

open access: yesMolecular Oncology, EarlyView.
This study identifies ARHGAP5, in addition to the frequently mutated ARHGAP35, as significantly mutated in endometrial cancer. Mutations in both genes co‐occur and are associated with their correlated downregulation. Functional CRISPR studies show that both paralogs regulate similar pathways, including actin cytoskeleton organization.

68 Ga-PSMA-PET/CT for the evaluation of pulmonary metastases and opacities in patients with prostate cancer

open access: yesCancer Imaging, 2018
Background The purpose of this study was to investigate the imaging properties of pulmonary metastases and benign opacities in 68Ga-PSMA positron emission tomography (PET) in patients with prostate cancer (PC).

IGF2 knockout reduces but does not abolish osteosarcoma growth in vitro and in vivo

open access: yesFEBS Open Bio, EarlyView.
To test whether endogenous IGF2 promotes osteosarcoma growth, IGF2 was knocked out in Saos2 cells via CRISPR‐Cas9. KO cells showed reduced proliferation in vitro, and knockout xenografts in mice reached only ~25% of wild‐type tumor volume. Insulin‐like growth factor 2 (IGF2) is implicated in osteosarcoma, but direct functional evidence of its role is ...

Refractile superficial retinal crystals and chronic retinal detachment: Case report

open access: yesBMC Ophthalmology, 2006
Background Few previous reports have described the presence of retinal refractile opacities at the macular area in patients presenting with longstanding peripheral retinal detachment. The exact nature of these opacities is unknown.

Chest CT imaging features of COVID-19 pneumonia: First radiological insights from Porto, Portugal

open access: yesEuropean Journal of Radiology Open, 2020
Introduction: The outbreak of a highly infectious respiratory disease – COVID-19 - has spread globally and a novel type of coronavirus (SARS-CoV-2) was identified as its cause.

Comprehensive Assessment of Arterial, Tissue, and Venous Collaterals for Evaluating the Infarct Growth Rate: The Multimodal Collateral Score

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Collaterals are crucial factors that influence the infarct growth rate (IGR). We aimed to determine whether a comprehensive multimodal collateral score (MCS), incorporating collateral assessment at the arterial, tissue, and venous levels, is associated with functional independence and provides incremental prognostic value over ...

Demarcated Opacities as Predictors of Progression of the Molar Incisor Hypomineralisation: a Pilot Study

open access: yesActa Stomatologica Croatica, 2020
Objectives: Demarcated opacities (DO) on teeth affected by Molar Incisor Hypomineralisation (MIH) were observed to investigate if parameters of DO existence and the number of teeth affected could be used to predict the progression of disease.

The Relationship between IGM Lyα Opacity and Galaxy Density near the End of Reionization

open access: yesThe Astrophysical Journal, 2023
Observed scatter in the Ly α opacity of quasar sightlines at z < 6 has motivated measurements of the correlation between Ly α opacity and galaxy density, as models that predict this scatter make strong and sometimes opposite predictions for how they ...
