We present optical spectroscopy of the host galaxies of 4 QSO’s: PG 1444+407, PKS 2349-147, 3C 323.1, and 4C 31.63 having a redshift range 0.1 ≤ z ≤ 0.3. The spectra were obtained at the Keck Observatory with the LRIS instrument offset 2-4 arcseconds from the nucleus at several position angles in each galaxy. The objects close to 3C 323.1 and PKS 2349-147 have the same redshifts of their nearby...
The interaction of lipoprotein lipase (LPL) with heparan sulfate proteoglycans plays an important role in the metabolism and catalytic function of the enzyme. We have used site-directed mutagenesis to replace the basic residues contained in a discontinuous charge cluster (residues Lys 321, Arg 405, Arg 407, Lys 409, Lys 415, and Lys 416) of avian LPL with asparagine. The mutant proteins were ex...
The equine herpesvirus 1 (EHV-1) immediate-early (IE) phosphoprotein is essential for the activation of transcription from viral early and late promoters and regulates transcription from its own promoter. The EHV-1 EICP22 protein, a homolog of ICP22 of herpes simplex virus, increased the in vitro DNA binding activity of the IE protein for sequences in the IE, early, and late promoters. The EICP...
Monoamine oxidase (MAO) is a key enzyme responsible for the degradation of serotonin, norepinephrine, dopamine, and phenylethylamine. It is an outer membrane mitochondrial enzyme existing in two isoforms, A and B. We have recently generated 14 site-directed mutants of human MAO A and B, and we found that four key amino acids, Lys-305, Trp-397, Tyr-407, and Tyr-444, in MAO A and their correspond...
Antibiotics and antiinflammatory agents are the primary and main therapeutic categories in the treatment of otitis media. One of the simpler and feasible approaches of minimizing the problem of repeated use and subsequent resistance is development of sustained release formulation. Therefore, the present investigation aimed to develop a sustained release in situ gel formulation containing combin...
The morbidity rate of hypertriglyceridemic acute pancreatitis (HTG-AP) increased rapidly over the last decade. However an appropriate animal model was lacking to recapitulate this complicated human disease. We established a novel mice model of HTG-AP by poloxamer 407 (P-407) combined with caerulein (Cae). In our study, serum triglyceride levels of P-407 induced mice were elevated in a dose-depe...
