The epitope recognized by a mouse monoclonal antibody (MAb) to the crystalline surface layer protein of Rickettsia typhi, SRT10, was mapped to 10 amino acid residues (SRTag TFIGAIATDT). The oligonucleotide sequence covering the epitope recognized by SRT10 was inserted into a mammalian expression vector together with multiple cloning sites. When the SRTag was fused in frame to the coding region ...

People who interact with rangelands on a regular basis gain practical insights about how rangelands work by living on and working with them. This local knowledge is refi ned over time as individuals see the way the land responds to weather, management, and disturbances. Local knowledge (LK) is a type of knowledge “integrally linked with the lives of people, always produced in dynamic interactio...

Objective Y chromosome deletions (YCDs) in azoospermia factor (AZF) region are associated with abnormal spermatogenesis and may lead to azoospermia or severe oligozoospermia. Assisted reproductive technologies (ART) by intracytoplasmic sperm injection (ICSI) and testicular sperm extraction (TESE) are commonly required for infertility management of patients carrying YCDs. The aim of this study w...

Software transactional memory (STM) offers a disciplined concurrent programming model for exploiting the parallelism of modern processor architectures. This paper presents the first deterministic specification automata for strict serializability and opacity in STMs. Using an antichain-based tool, we show our deterministic specifications to be equivalent to more intuitive, nondeterministic speci...

Yeast artificial chromosome (YAC) clones carrying DNA marker sequences located on the rice genetic map of chromosome 6 were ordered for physical mapping. A total of 122 restriction fragment length polymorphism markers, 16 sequence-tagged site markers, and five random amplified polymorphic DNA markers located, on average, at 0.9-cM intervals, were used for YAC clone screening by colony/Southern ...

Oryza meyeriana is highly resistant to rice bacterial blight (BB) and this resistance trait has been transferred to cultivated rice (O. sativa) using asymmetric somatic hybridization. However, no resistance genes have yet been cloned. In the present study, a progeny of the somatic hybridization with high BB resistance was crossed with a rice cultivar with high BB susceptibility to develop an F2...

We present a physical map based on RAPD polymorphic fragments and sequence-tagged sites (STSs) for the repleta group species Drosophila buzzatii. One hundred forty-four RAPD markers have been used as probes for in situ hybridization to the polytene chromosomes, and positive results allowing the precise localization of 108 RAPDs were obtained. Of these, 73 behave as effectively unique markers fo...

We describe a new method for gene discovery and analysis, CD-tagging, that puts specific molecular tags on a gene, its transcript and its protein product. The method has been successfully tested in two organisms, the haploid unicellular alga Chlamydomonas reinhardtii and the metazoan Drosophila melanogaster. The method utilizes a specially designed DNA molecule, the CD-cassette, that contains s...

conclusions in the present study, the highest prevalence was for st5, which is so important for epidemiology and risk of human infection. the report related to st3 in cattle as a subtype of human showed mutual infection between human and cattle. another important point in this study was the st6 report. finally, it seems that gathering epidemiological data is needed for a better understanding of...
