Intermolecular Interactions Between Formaldehyde And Dimethyl Ether And Between Formaldehyde Abd Dimethyl Sulfide In The Complex, Investigated By Fourier Transform Microwave Spectroscopy And Ab Initio Calculations
No full textThe ground-state rotational spectra of the formaldehyde-dimethyl ether (\chem{H_2CO-DME}) and the formaldehyde-dimethyl sulfide (\chem{H_2CO-DMS}) complexes have been studied by Fourier transform microwave spectroscopy, and -type and -type transitions have been observed and assigned for the \chem{H_2CO} as well as \chem{D_2CO} species of both the complexes. In the case of the \chem{H_2CO-DME}, doublets were observed with the splitting of a few 100 kHz, whereas no such splitting was found for the \chem{H_2CO-DMS}. The observed rotational constants were analyzed to conclude a geometry, where DME and DMS were bound to \chem{H_2CO} by the two C-H(DME/DMS)---O(\chem{H_2CO}) and the two O(DME)/S(DMS)---H-C(\chem{H_2CO}) hydrogen bonds. The distances between the centers of mass of the constituents were determined to be 3.102 and 3.200 \AA for the two complexes, respectively. Both the \chem{H_2CO-DME} and \chem{H_2CO-DMS} complexes were shown by the natural bond orbital (NBO) analysis, to have strong charge transfer interactions between the constituents, as expected from the strong electron-accepting character of the \chem{H_2CO}.Made available in DSpace on 2014-09-17T16:56:33Z (GMT).

Immunohistochemical study of placental alkaline phosphatase in seminoma
No full text正常睾丸組織および精上皮腫と非精上皮腫を含む睾丸腫瘍組織のPLAP染色を行った.1)正常睾丸組織および胎児性癌組織ではPLAPは染色されなかった.2)精上皮腫ではPLAPの染色を認め, 主に細胞膜に, 一部細胞質に局在がみられた.3)精上皮腫において腫瘍細胞の浸潤のない正常精細管内胚細胞と思われる細胞にも染色を認め, carcinoma in situの存在が推測されたIndirect immunoperoxidase staining was carried out on seminomatous tumors of testes (22 specimens) using anti-placental alkaline phosphatase antibody to search for the usefulness of placental alkaline phosphatase as a tumor marker. All of the seminomas showed positive staining mainly on the cell surface. However, the normal testes and non-seminomas showed negative staining. Of interest, normal tissues outside the tumor mass showed positive staining. This phenomenon is considered to be suggestive of carcinoma in situ. Immunohistochemical study of placental alkaline phosphatase on the seminomas is a useful method for histopathological diagnosis and may be useful for understanding the pathogenesis of the tumor
