A-16686, a new glycoproteide antibiotic from Actinoplanes sp., was evaluated as a potential antiplaque agent in comparison with chlorhexidine, benzalkonium chloride, and cetylpyridinium chloride. A-16686 had good activity against gram-positive organisms associated with dental plaque (various streptococci, Streptococcus mutans in particular, lactobacilli, Actinomyces viscosus, and Actinomyces na...

OBJECTIVE Among indirect measures of visceral adiposity, A Body Shape Index (ABSI), which is defined as waist circumference (WC)/(body mass index (BMI)(2/3)×height(1/2)), is unique in that ABSI is positively correlated with visceral adiposity and is supposed to be independent of BMI. ABSI has been also shown to be linearly and positively associated with visceral fat mass and all-cause and cardi...

* Work supported by National Science Foundation † Phone: (607) 255-3785, Fax: (607) 255-8062, e-mail: [email protected] Abstract Design of dual bore superconducting quadrupole for CESR upgrade is represented. The lens has a gradient about 1 kG/cm, dual aperture of 54 mm each, length about 800 mm, The axes spacing about 80 mm allows a good separation of counter rotating beams. Harmon...

Homonuclear 2D NMR spectroscopy double quantum filter correlation spectroscopy (DQF-COSY), relayed-COSY, nuclear Overhauser enhancement spectroscopy (NOESY), and DQF-relayed-NOESY) allowed the complete determination of the core depsipeptide of antibiotic ramoplanin (A-16686). In particular, the DQF-relayed-NOESY experiments were essential in assigning the single signals close to the diagonal.

Respectively, exogenous pamamycin-607 and A-factor restored or stimulated aerial mycelium formation in 30 (67%) and 6 (13%) of 45 Streptomyces strains, and both restored or stimulated it in 5 strains (11%). Pamamycin-607 production was detected in 3 of those strains that responded to pamamycin-607. These findings indicate that pamamycin-607 acts on the common regulatory system for aerial myceli...

Resonance Raman and absorption spectra were examined for the species generated upon incubation of oxidized bovine cytochrome c oxidase at pH 8.0 with carbon monoxide in the presence or absence of O2. The anaerobic incubation yielded the CO isotope sensitive bands at 517 and 578 cm–1 for 12C16O, at 512 and 563 cm–1 for 13C16O, at 508 and 574 cm–1 for 12C18O, and at 503 and 557 cm–1 for 13C18O, i...

PURPOSE Determining the ideal length of a ureteric stent is important to avoid complications associated with stent placement. Clinically, most urologists usually choose the length of a ureteric stent according to the patient's height. On the basis of a Chinese population study, a 22 cm ureteric stent has been recommended for patients smaller than 175 cm. We evaluated the appropriateness of this...
