Effect of adulteration versus storage on volatiles in unifloral honeys from different floral sources and locations.
J. Food Sci. 78(2) , C184-91, (2013) High fructose corn syrup (HFCS) was added at 5% to 40% to Indiana wildflower honey and added at 40% to Ohio and Indiana honeys from blueberry, star thistle, clover and wildflower, and an unknown source to simulate honey adulteration. Unadulterated honeys were... |

Glass-forming tendency in the system water-dimethyl sulfoxide.
Cryobiology 40(2) , 151-8, (2000) The glass-forming tendency on cooling and the stability of the wholly amorphous state on warming have been previously reported for many cryoprotective solutions. However, unlike the other solutions, those of dimethyl sulfoxide (Me(2)SO) have not been studied ... |

Feasibility of cryopreservation of zebrafish (Danio rerio) primordial germ cells by whole embryo freezing.
Jpn. J. Vet. Res. 57(2) , 119-28, (2009) We investigated the feasibility of cryopreservation of zebrafish (Danio rerio) blastomeres and primordial germ cells (PGCs) by rapid freezing of dechorionated whole embryos at the blastula, gastrula and segmentation stages. Initially we examined the glass-for... |

Conformational equilibria in diols: the rotational spectrum of chiral 1,3-butandiol.
J. Phys. Chem. A 115(34) , 9585-9, (2011) The rotational spectra of five conformers of 1,3-butandiol have been measured by pulsed jet Fourier transform microwave spectroscopy. All of them are stabilized by an internal hydrogen bond and all of them have a GG' or a G'G arrangement of the two hydroxyl o... |

Attenuation of brain hyperbaric oxygen toxicity by fasting is not related to ketosis.
Undersea Hyperb. Med. 26(2) , 99-103, (1999) The effect of 24 h of fasting and changes in blood glucose and beta-hydroxybutyrate (BHB) level on latency to seizures in hyperbaric oxygen (HBO2) was studied. Conscious, unrestrained rats implanted with cortical electroencephalogram electrodes were exposed t... |
