    Notes: Abstract Human fetal muscle cDNA library was screened with aβ-myosin heavy chain gene fragment containing Alu sequences. Two cDNA clones AI and BII with 1.8 and 3 kb inserts respectively were chosen for further characterization by means of RNA and DNA hybridization procedures and sequencing. The clones appeared to contain repetitive sequences as well as single copy regions. They are actively transcribed in different stages of myogenic development but not in the liver. DNA sequence analysis of short stretches from both clones revealed no sequence homology to any other published DNA sequences.

    Notes: Raman spectra in the C—H and S=O stretching and S=O bending regions are reported for solutions of lithium halides and tetrabutylammonium bromide (TBAB) in dimethyl sulphoxide (DMSO) and DMSO-d6. The C—D stretching band of DMSO-d6 shows two components in solutions of TBAB with DMSO-d6, whereas the C—H stretching band of DMSO for solutions of LiX (X = Br and I) in DMSO show some broadening and asymmetry in the low-frequency region. The S=O stretching bands show changes in band shapes and band contours in solutions of electrolytes in DMSO. Fourier deconvolution of C—H and S=O stretching bands were carried out to gain more information regarding number of components present under the broad structured bands. All the solutions show a significant decrease in the intensity of the S=O bending bands when compared with the neighbouring C—S bending band. The results are discussed in terms of anion- and cation-molecular interactions with DMSO.

    Raman spectral studies of aqueous solutions of non-electrolytes: Dimethylsulfoxide, acetone and acetonitrilePresented at 6th International Conference on Raman Spectroscopy, Bangalore, India (1978). (1982)

    Notes: Raman spectra of aqueous solutions of dimethylsulfoxide, dimethylsulfoxide-d6, acetone and acetonitrile are reported in the OH stretching region, and in the stretching regions of the functional groups of these solutes. Raman intensities and frequency shifts of these bands show definite trends with varying concentrations of the solutions. The results obtained are discussed in terms of the mixture model of water, and they are compared with results obtained from Raman spectral studies of aqueous electrolytes. It is proposed that water structure breaking and the formation of solute-solvent complexes when organic solutes are added to water can account for these results.

    Self-association of dimethyl sulphoxide and its dipolar interactions with water: Raman spectral studies (1984)

    Notes: Raman spectra of solutions of dimethyl sulphoxide (DMSO) in carbon tetrachloride (CCl4) and water are reported for both parallel and perpendicular polarizations in the S=O stretching region. The various bands obtained were subjected to Gaussian band fittings. It was observed that the bands for solutions in CCl4 may be fitted satisfactorily by considering four components and those for solutions in water may be fitted by considering five components. It is inferred that the band at ca 1070 cm-1 observed in the spectra of DMSO in CCl4 belongs to the S=O stretching mode of free DMSO, whereas the two bands observed at ca 1058 cm-1 and ca 1040 cm-1 belong to out-of-phase and in-phase S=O stretchings of the cyclic dimer. The low-frequency band at ca 1025 cm-1 is assigned to linear dimer/higher polymers. Aqueous solutions of DMSO show an additional band at ca 1010 cm-1 due to DMSO hydrogen-bonded with water.
