Metal oxide charge transport materials are preferable for realizing long-term stable and potentially low-cost perovskite solar cells(PSCs).However,due to some technical difficulties(e.g.,intricate fabrication protocols,high-temperature heating process,incompatible solvents,etc.),it is still challenging to achieve efficient and reliable all-metal-oxide-based ***,we developed efficient inverted PSCs(IPSCs)based on solution-processed nickel oxide(NiO_(x))and tin oxide(SnO_(2))nanoparticles,working as hole and electron transport materials respectively,enabling a fast and balanced charge transfer for photogenerated charge *** further understanding and optimizing the perovskite/metal oxide interfaces,we have realized an outstanding power conversion efficiency(PCE)of 23.5%(the bandgap of the perovskite is 1.62 eV),which is the highest efficiency among IPSCs based on all-metal-oxide charge transport *** to these stable metal oxides and improved interface properties,ambient stability(retaining 95%of initial PCE after 1 month),thermal stability(retaining 80%of initial PCE after 2 weeks)and light stability(retaining 90%of initial PCE after 1000 hours aging)of resultant devices are enhanced *** addition,owing to the low-temperature fabrication procedures of the entire device,we have obtained a PCE of over 21%for flexible IPSCs with enhanced operational stability.

A total of 719 expressed sequence tags （EST） clustered into 329 non-redundant EST groups are obtained from the sporophyte cdNA library of red algae, Porphyra yezoensis. Gene Ontology （GO） analysis is employed in characterizing 60 strictest annotated unique genes out of the 329 EST groups and some domains such as COX1, SodFeC, GST-N, SHMT, and RNase-PH related to the enzymes and proteins functioning in cells have been identified by HMMPFAM search. As its leafy gametophyte, the similar codon usage with strong bias is found in P. yezoensis filamentous sporophyte, regardless of some differences found in given amino acids. The average GC content of the 329 unique genes is 53. 0 % . In contrast, the third nucleotide of codon exhibits a higher GC content （ 72 % ） than that of the first （58%） and the second （42%） nucleotides. Similarity search of the present study shows a novel EST ratio of 60.2%, which is against the Porphyra ESTs database, suggesting further investigations towards elucidating the characteristics of Porphyra functional genome.

The genome-wide transcription profile of deinococcus radiodurans cells was investigated after treatment with low dose irradiation (2 kGy). From the expression profile, we found that the process of dNA repair was induced in order, i.e. genes involved in base excision repair, nucleotide excision repair and single-strand annealing were induced immediately after ionizing radiation, and genes for recombination repair, including recA, recd and recQ were then activated. Especially, recd and recQ were specifically induced at low dose irradiation, and this phenomenon informed us that these two genes would play a certain role in anti-oxidation. Some genes such as ddrA and ssb were activated during the whole repair phase. Furthermore, the response of oxidative stress-related genes under low dose irradiation showed a different pattern from that of the acute high-level irradiation, many anti-oxidative genes were induced to scavenge reactive oxygen species directly, other associated systems also changed their expression patterns during the recovery time, such as iron metabolism systems, intracellular mutagenic precursors sanitize systems. These characteristics indicate that there is a powerful and orderly recovery process in deinococcus radiodurans.

Insm1:orchestrating cellular mimicry in the thymus medulla

Every student package automatically includes a Cd-ROM and access to a website containing tutorials, molecular models, and *** long-awaited Fifth Edition of james d. watson's classic text, Molecular Biology of the Gene, has been thoroughly revised and is published to coincide with the 50th anniversary of watson and Crick's paper on the structure of the dNA double- *** being completely updated, the new edition retains the distinctive character of earlier editions that made it the most widely used book in molecular biology. Twenty-one concise chapters, co-authored by five highly respected molecular biologists, provide current, authoritative coverage of a fast-changing discipline. The completely new art is printed in full colour for the first *** into four parts, the first (Genetics and Chemistry) begins with an overview of molecular biology, placing the discipline in historical context and introducing the basic chemical concepts that underpin our description of molecular biology today. The second part (Central dogma) forms the heart of the book, describing in detail the basic mechanisms of molecular biology. The third part of the book (Regulation) deals with how gene expression is regulated - from the examination of basic mechanisms that regulate gene expression in bacterial and eukaryotic systems, to a description of how regulation of gene expression lies at the heart of the process of development. Recent findings from sequencing whole genomes of several animals have revealed that they all share essentially the same genes. The last chapter in the regulation section looks at how changes in gene regulation can account for how different animals can be made from the same genes. The final part of the book (Methods) deals with the techniques and methods used in molecular biology.[Contents]I. CHEMISTRY ANd GENETICS.1. The Mendelian View of the World.2.

The thymus is the primary production site for a functional and self-tolerant T-cell *** establishment of immune tolerance is mediated by the generation and presentation of tissue-restricted self-antigens(TRAs)by medullary thymic epithelial cells(mTECs),which screen T-cell receptors for self-reactivity to eliminate autoreactive T *** studies have extended our understanding of mTEC heterogeneity by examining the mechanisms by which mTECs mimic the peripheral self[1].

Expressed sequence tags (ESTs) are widely used in gene survey research these years. The EST Pipeline System, software developed by Hangzhou Genomics Institute (HGI), can automatically analyze different scalar EST sequences by suitable methods. All the analysis reports, including those of vector masking, sequence assembly, gene annotation, Gene Ontology classification, and some other analyses, can be browsed and searched as well as downloaded in the Excel format from the web interface, saving research efforts from routine data processing for biological rules embedded in the data.
