抗原变异可使得多种致病微生物易于逃避宿主免疫应答。表达在感染红细胞表面的恶性疟原虫红细胞表面蛋白1（PfPMP1）与感染红细胞、内皮细胞、树突状细胞以及胎盘的单个或多个受体作用，在黏附及免疫逃避中起关键的作用。每个单倍体基因组var基因家族编码约60种成员，通过启动转录不同的var基因变异体为抗原变异提供了分子基础。read more

TL;DR: Specific developments discussed include fast methods for density functional theory calculations, linear scaling evaluation of energies, NMR chemical shifts and electric properties, fast auxiliary basis function methods for correlated energies and gradients, equation-of-motion coupled cluster methods for ground and excited states, geminal wavefunctions, embedding methods and techniques for exploring potential energy surfaces.

The Transcriptional Landscape of the Yeast Genome Defined by RNA Sequencing
Ugrappa Nagalakshmi,Zhong Wang,Karl Waern,C. Shou,Debasish Raha,Mark Gerstein,Michael Snyder +6 more
TL;DR: A quantitative sequencing-based method is developed for mapping transcribed regions, in which complementary DNA fragments are subjected to high-throughput sequencing and mapped to the genome, and it is demonstrated that most (74.5%) of the nonrepetitive sequence of the yeast genome is transcribed.

A "Silent" Polymorphism in the MDR1 Gene Changes Substrate Specificity
Chava Kimchi-Sarfaty,Jung Mi Oh,In-Wha Kim,Zuben E. Sauna,Anna Maria Calcagno,Suresh V. Ambudkar,Michael M. Gottesman +6 more
TL;DR: It is hypothesized that the presence of a rare codon, marked by the synonymous polymorphism, affects the timing of cotranslational folding and insertion of P-gp into the membrane, thereby altering the structure of substrate and inhibitor interaction sites.

TL;DR: The iron cycle, in which iron-containing soil dust is transported from land through the atmosphere to the oceans, affecting ocean biogeochemistry and hence having feedback effects on climate and dust production, is reviewed.

TL;DR: DNA resequencing of the complement factor H gene within this haplotype revealed a common coding variant that significantly increases the risk for AMD with odds ratios between 2.45 and 5.57, which likely explains ∼43% of AMD in older adults.

TL;DR: This work shows that graphene's electronic structure is captured in its Raman spectrum that clearly evolves with the number of layers, and allows unambiguous, high-throughput, nondestructive identification of graphene layers, which is critically lacking in this emerging research area.

Finding and evaluating community structure in networks.
TL;DR: It is demonstrated that the algorithms proposed are highly effective at discovering community structure in both computer-generated and real-world network data, and can be used to shed light on the sometimes dauntingly complex structure of networked systems.
