7. Surface structures and electronic states of clean and (NH4)2Sx-treated InAs(111)A and (111)

Abstract

Research was conducted to examine surface structures and electronic states of clean and (NH4)2Sx-treated InAs(111)A and (111)B using low-energy electron diffraction, x-ray photoelectron spectroscopy and ultraviolet photoelectron spectroscopy (UPS). To investigate the dangling bond states for the sulfur-treated surfaces, UPS measurements and inverse photoemission spectroscopy were utilized. Results indicate that sulfur is bonded to both indium and arsenin on the (111)B surface annealed at less than 340 degrees C and bonded only to indium at 420 degrees C.

33. Comparative study of polymorphisms on genes associated with lifestyle related diseases in Asian and Pacific populations.

Abstract

An increase in prevalence of lifestyle related diseases becomes one of the main threats to human health in Asia-Pacific regions. Especially Pacific countries face the marked epidemic of obesity and related disorders. Understanding of the genetic basis for these diseases is awaited. We investigated frequencies of 106 single nucleotide polymorphisms (SNPs) in genes associated with lifestyle related diseases in 1,878 individuals from five Asia-Pacific countries including Japan, China, Mongolia, Thailand, and Palau. Population genetic analyses revealed that disease susceptible variants of SNPs in TRIB3, PTGS2, ADIPORI, DGAT1, UCP2, FOXC2, and ESR1 were overrepresented in the Palau population in comparison with the Asian populations. These gene variants likely contribute to the high prevalence of obesity and related diseases in Pacific populations. The present results would be helpful in coping with the lifestyle related diseases and may provide a new insight into the human dispersal in Asia-Pacific regions. [ABSTRACT FROM AUTHOR]

36. Gene expression profiles in Ciona intestinalis tailbud embryos.

Abstract

A set of 3423 expressed sequence tags derived from the Ciona intestinalis tailbud embryos was categorized into 1213 independent clusters. When compared with DNA Data Bank of Japan database, 502 clusters of them showed significant matches to reported proteins with distinct function, whereas 184 lacked sufficient information to be categorized (including reported proteins with undefined function) and 527 had no significant similarities to known proteins. Sequence similarity analyses of the 502 clusters in relation to the biosynthetic function, as well as the structure of the message population at this stage, demonstrated that 390 of them were associated with functions that many kinds of cells use, 85 with cell-cell communication and 27 with transcription factors and other gene regulatory proteins. All of the 1213 clusters were subjected to whole-mount in situ hybridization to analyze the gene expression profiles at this stage. A total of 387 clusters showed expression specific to a certain tissue or organ; 149 showed epidermis-specific expression; 34 were specific to the nervous system; 29 to endoderm; 112 to mesenchyme; 32 to notochord; and 31 to muscle. Many genes were also specifically expressed in multiple tissues. The study also highlighted characteristic gene expression profiles dependent on the tissues. In addition, several genes showed intriguing expression patterns that have not been reported previously; for example, four genes were expressed specifically in the nerve cord cells and one gene was expressed only in the posterior part of muscle cells. This study provides molecular markers for each of the tissues and/or organs that constitutes the Ciona tailbud embryo. The sequence information will also be used for further genome scientific approach to explore molecular mechanisms involved in the formation of one of the most primitive chordate body plans.

37. Immunohistochemical Detection of Sialyl LeX Antigen on Mucosal Langerhans Cells of Human Oral Mucosa following Neuraminidase Pretreatment

Author

Ohno, J., Ohshima, Y., Arakaki, Z., Yokoyama, S., and Utsumi, N.

Abstract

Histochemical assessment of selected carbohydrate sequences on Langerhans cells of human oral mucosa was made by combined use of enzyme digestion and immunostain-ing with monoclonal antibodies against specific carbohydrate structures. In both frozen sections and epithelial sheets without the enzyme pretreatment, mucosal Langerhans cells, identified by positive staining with anti-CD1a and HLA-DR antibodies, did not express any carbohydrate antigens on their surface. In contrast, following neuraminidase pretreatment of both types of material, the fucosylated type 2 chain (LeX) became detectable on Langerhans cells, indicating that sialic acid is the terminal residue of this sequence. Other enzymes were ineffective in this apparent unmasking, and the staining patterns of the other related carbohydrate sequences (Ley. Lea, Leb) remained unaffected by pretreatment with any of the enzymes used. These findings suggest that the mucosal Langerhans cells possess a unique carbohydrate chain, the sialyl fucosylated type 2 sequence (sialyl LeX antigen).

39. DNA-based diagnostics in the study of heritable and acquired disorders

Abstract

Recent advances in molecular biology techniques have made DNA diagnostics a reality. A major advance was the development of the polymerase chain reaction, which allows the direct analysis of a region of a known gene from minute quantities of template DNA. The DNA can even be isolated from such sources as saliva, hair roots, microscope slides, paraffin-embedded tissue, and clinical swabs, in addition to blood and biopsy material. Another major improvement is the development of automated procedures suitable for robotic stations. Together these improvements make DNA analysis an important part of diagnostic procedures in studying the etiology of diseases.
