An Ecological Correlation Study of Late Age-Related Macular Degeneration and the Complement Factor H Y402H Polymorphism

open access: yes, 2009
PURPOSE: To investigate whether variation in the distribution of the risk allele frequency of the Y402H single-nucleotide polymorphism (SNP) across various ethnicities and geographic regions reflects differences in the prevalence of late age-related ...

Glissile Interphase Boundaries Enable Collective Phase Switching in Epitaxial Polar Oxides

open access: yesAdvanced Functional Materials, EarlyView.
A triple point is identified in the phase diagram of low‐symmetry epitaxial BiFeO3 thin film along with an extended regime of phase competition associated with a flattened energy landscape. The electromechanical response is shown to be governed by correlated interphase‐boundary motion, including scale‐free avalanche dynamics characteristic of systems ...

Molecular genetic studies on Brassica napus L. [PDF]

open access: yes, 1991
The feasibility of using two different methods of assaying for DNA polymer phisms has been assessed. They were Restriction fragment length polymorphisms (RFLPs) as revealed by a range of characterised Brassica cDNA sequences and Random amplified ...

Bio‐Inspired Synthesis of Macroporous Single Crystal Particles as Scattering Agents

open access: yesAdvanced Functional Materials, EarlyView.
A general strategy is presented that delivers unique, single‐crystal microparticles that combine submicron macroporosity and uniform particle shapes. A bioinspired approach is used to occlude three distinct types of additives – polystyrene microspheres, polymer vesicles and amino acids – within calcite single crystals, and subsequent thermal annealing ...

Genetic Polymorphism

open access: yes, 2017
The human DNA is exposed to a number of changes, these changes are frequently carried out in one or few nucleotides called mutations, which can be caused by errors in the mechanisms of DNA replication and repair as well as by environmental factors; and these mutations can have deleterious effects and cause disease.

Chitin‐Derived Carbon‐Metal Functional Materials

open access: yesAdvanced Functional Materials, EarlyView.
Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.

High‐Throughput Discovery of Quantum Frustrated Materials

open access: yesAdvanced Functional Materials, EarlyView.
Physics‐guided discovery of frustrated kagome and triangular magnets. ABSTRACT Geometrical frustration provides a fertile platform for realizing exotic quantum phases such as spin liquids, yet, the predictive identification of frustrated magnets remains limited.

Influência de combinações genéticas nos níveis de HDL-c em uma população do sul do Brasil Influencia de combinaciones genéticas en los niveles de HDL-c en una población del sur del Brasil Influence of genetic combinations on HDL-C levels in a Southern Brazilian population

open access: yesArquivos Brasileiros de Cardiologia, 2010
FUNDAMENTO: Baixos níveis de HDL-c são importantes preditores de doença coronariana, a primeira causa de morte no mundo todo. Muitos fatores afetam os níveis de HDL-c, tais como os polimorfismos de genes que codificam proteínas-chave para a via de ...
