Impact of Race on the Outcomes of Retinoblastoma Treated With Primary Enucleation: A Global Study of 1426 Patients.
Clin Exp Ophthalmol
December 2024
King Hussein Cancer Center, Amman, Jordan.
Background: To evaluate the clinical presentation, pathological features and outcomes of retinoblastoma based on the race of origin in a global cohort of patients.
Methods: Retrospective collaborative study of 1426 patients who underwent primary enucleation for retinoblastoma.
Results: Patients were grouped into Caucasians (n = 231, 16%), Asians (n = 841, 59%), Hispanics (n = 226, 16%), Arabs (n = 96, 7%) and Others (Africans, African Americans, Indigenous Australians; n = 32, 2%) cohorts.
Orbital and suborbital temperature variability in the central Mediterranean across the Pliocene/Pleistocene transition.

A high-resolution record of central Mediterranean Sea Surface Temperatures (SSTs) based on the alkenone UK'37 index and planktic δ18O values for the surface-dweller G. ruber has been reconstructed across the Pliocene/Pleistocene transition at Monte San Nicola (Sicily), reference area for the GSSP (Global Boundary Stratotype Section and Point) of the Gelasian Stage. Spectral analyses indicate that the SST record is predominantly paced by a cyclicity in the ~47 kyr time domain, consistent with the obliquity driven glacial-interglacial variability that is expected to dominate in the interval of relevance.

HfO-based multi-bit ferroelectric memory combines non-volatility, speed, and energy efficiency, rendering it a promising technology for massive data storage and processing. However, some challenges remain, notably polarization variation, high operation voltage, and poor endurance performance. Here we show Hf ZrO (x = 0.

Many fluorophores display interesting features that make them useful biological labels and dyes, particularly in Cell Biology and Cytogenetics. Changes in the absorption-emission spectra (ortho- and metachromasia) are accounted among them. Acridine orange (AO) is one of such fluorochromes with an exemplary orthochromatic vs.

Castleman disease is a lymphadenopathy of unknown cause at a single site, which is designated as unicentric Castleman disease, or at multiple sites designated as multicentric Castleman disease. We present a patient who showed axillary reactive lymphoid hyperplasia, likely due to unicentric Castleman disease, and orbital extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) lymphoma in a six-year follow-up. A 76-year-old man had a painless left axillary mass for an unknown period and also left complete blepharoptosis with no other systemic symptoms.
