Intradialytic parenteral nutrition improves nutritional status in a complex cystic fibrosis patient with redo double lung transplant and end-stage renal disease.

This case study reports on the use of intradialytic parenteral nutrition (IDPN) to address severe malnutrition in a 38-year-old woman, redo double lung transplant recipient with a complex medical history including cystic fibrosis and end-stage renal disease (ESRD) on haemodialysis. Gastroparesis and severe postprandial abdominal pain limited oral/enteral nutrition input. The addition of IDPN resulted in a dry weight increase of 13.

Exposure to cyclic oxygen sufficient for development of oxygen-induced retinopathy does not induce bronchopulmonary dysplasia in rats.

Bronchopulmonary dysplasia and retinopathy of prematurity affect premature infants exposed to supplemental oxygen. Susceptibility to oxygen-induced retinopathy in the rat is heritable, with inbred Dark Agouti (DA) rats being more susceptible than Fischer 344 (F344) rats. To establish if hyperoxic exposure sufficient to induce florid retinopathy would induce strain-specific lung changes, newborn DA and F344 rats were exposed to cyclic hyperoxia or room air for up to 18 days.

The application of direct potential fitting to the X1sigma+ ground electronic states of LiCl, TlCl, RbF and CsF.

A procedure for directly fitting the potential energy curve of a diatomic molecule has been applied to the X1sigma+ ground states of LiCl, TlCl, RbF and CsF. Extensive, high-precision infrared and pure-rotational data sets for all isotopomers of the aforementioned molecules have been employed in direct least-squares fits of a radially dependent Hamiltonian operator. The Born-Oppenheimer potentials are represented by a modified Lennard-Jones function that is shown to be flexible and provide the proper behavior in the long-range region of the potential.

High-Resolution Laser Spectroscopy of YbCl: The A(2)Pi-X(2)Sigma(+) Transition.

The A(2)Pi-X(2)Sigma(+) transition of (174)Yb(35)Cl and (172)Yb(35)Cl has been rotationally analyzed for the first time. Doppler-limited laser excitation spectroscopy with selective detection of fluorescence was used to obtain spectra of the 0-0 and 1-0 bands with a measurement accuracy of approximately 0.0035 cm(-1).

Mixed culture studies of Streptococcus mitis and oral enterococci.

Strains of Streptococcus mitis and oral enterococci were grown in mixed culture in 0.5% peptone, 1.0% peptone and 1.

Inhibitory activity of Streptococcus mitis against oral bacteria.

The antagonistic properties of three strains of Streptococcus mitis were investigated. They were found to inhibit a wide range of oral bacteria; Gram-positive and Gram-negative, facultative and anaerobic species being susceptible. The S.

The influence of certain growth conditions on the phosphatase activity of Streptococcus mutans grown in batch and continuous culture.

Acid phosphatase activity was detected in Streptococcus mutans strain NCTC 10832, and both acid and alkaline phosphatase in strains 2M2 and K1R. In batch culture, activity was maximal by mid exponential phase for 2M2 and at the end of this phase for NCTC 10832. Alkaline, but not acid, phosphatase activity of 2M2 and K1R increased when the inorganic phosphate in the medium was low; this was considered due, at least partly, to inducible or derepressible enzymes.

Fatty acid profiles of Streptococcus mutans NCTC 10832 grown on synthetic mediun with sucrose, fructose or sorbitol.

Streptococcus mutans NCTC 10832 was grown on synthetic medium in a chemostat, using various major carbon sources, viz, sorbitol, fructose and sucrose. Freeze-dried cells were methylated and the methyl esters analysed by GLC. The fatty acid profiles obtained showed small quantitative change with different sugars, sucrose concentrations and types of growth.
