Chromosomal Gains and Losses in Uveal Melanomas Detected by Comparative Genomic Hybridization [PDF]

open access: yes, 1994
Eleven uveal melanomas were analyzed using comparative genomic hybridization (CGH). The most abundant genetic changes were loss of chromosome 3, overrepresentation of 6p, loss of 6q, and multiplication of 8q.

Engineering Iridium–Ruthenium Dual‐Atomic Active Sites on Redox‐Active Covalent Organic Frameworks for Boosted Overall Water Splitting

open access: yesSmall, EarlyView.
Atomically dispersed IrRu dual‐atomic sites are anchored on donor‐acceptor‐based redox‐active COF for overall water electrolysis, and the active sites separation mechanism induced by giant multifunctional active‐site synergistic enhancement (MASE) effect was explored by the operando spectroscopy and DFT calculations.

Patologie rare dell'orecchio [PDF]

open access: yes, 2012
After fifty years of experience, mostly spent in ENT surgery at the University of Palermo, I have pleasure in presenting this Atlas of rare diseases of the ear, including clinical cases observed and documented during this long period from 1958 to ...

Record‐Low Compressibility in [N(C2H5)3CH3]FeCl4 Expands Phase Engineering Horizons in Hybrid Molecular Ferroelectrics

open access: yesSmall, EarlyView.
High‐pressure studies of the lead‐free hybrid organic–inorganic ferroelectric [N(C2H5)3CH3]FeCl4 demonstrate record low compressibility, establishing it as the least compressible molecular ferroelectric known. In situ diamond anvil cell experiments identify halide selection and inorganic sublattice tuning as key compressibility controls, advancing ...

Simultaneous Formation of Arsenic Nitride Chalcogenides As3NS3 and As3NSe3 and Arsenic–Chalcogen Zintl Anions by Ammonothermal Reactions

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Mn, As, and S or Se react in liquid NH3 to the Zintl ions (As4S6)2– and (As2Se6)2–. Simultaneously, the arsenic nitride chalcogenides As3NS3 and As3NSe3 are formed. Their isotypic structures contain planar trigonal NAs3 groups connected via chalcogen bridges to 1D‐strands forming channels that can host solvent molecules.

BaYaka forager and Bantu fisher‐farmer adolescent engagement with intensifying market integration in the Republic of the Congo Participation des adolescents BaYaka chasseurs‐cueilleurs et Bantous pêcheurs‐agriculteurs à l'intégration croissante au marché en République du Congo

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
A substantial body of anthropological research has investigated how subsistence communities engage with market‐based economies. In this study, we contribute to this body of work by examining adolescent orientations towards intensifying market integration in the Congo Basin.

What can lithics tell us about hominin technology's ‘primordial soup’? An origin of stone knapping via the emulation of Mother Nature

open access: yesArchaeometry, EarlyView.
Abstract The use of stone hammers to produce sharp stone flakes—knapping—is thought to represent a significant stage in hominin technological evolution because it facilitated the exploitation of novel resources, including meat obtained from medium‐to‐large‐sized vertebrates. The invention of knapping may have occurred via an additive (i.e., cumulative)

The Phenotypic and Genotypic Features of ADAMTSL4‐Related Ocular Disease

open access: yesClinical Genetics, EarlyView.
ADAMTSL4‐related ocular disease tends to present at a younger age and be associated with higher myopia than other forms of ectopia lentis (such as FBN1). A previously reported 20‐bp deletion (c.767_786del) was highly prevalent in this cohort (23/32), and all ectopia lentis et pupillae cases carried this variant. ABSTRACT Pathogenic variants in ADAMTSL4

Why Can\u27t Doctors Spell? [PDF]

open access: yes, 1993
The illegibility of doctors\u27 handwriting has spawned innumerable jokes. Jottings that seem illegible and unintelligible may actually be technical terms that mimic commoner words.
