Influence of gustatory and olfactory functions on appetite and nutritional status in older persons.

This study investigated olfactory/taste functions in older persons requiring nursing care to clarify whether these functions are associated with appetite or nutritional status. Seventy-two older persons requiring nursing care and 37 unassisted persons were surveyed for olfactory function, taste function, appetite, and nutritional status. Age-adjusted covariance analysis was conducted between the two groups.

Effect of cryoprotectant composition on in vitro viability of in vitro fertilized and cloned bovine embryos following vitrification and in-straw dilution.

In this study the efficacy of the combination of glycerol (GLY) and ethylene glycol (EG) as cryoprotectants in a vitrification method developed for direct embryo transfer was evaluated by in vitro development of in vitro fertilized (IVF) and somatic cell nuclear transfer (SCNT) embryos after vitrification. The IVF and SCNT blastocysts were vitrified in either 40% GLY, 30% GLY + 10% EG, or 20% GLY + 20% EG using French straws. After warming, the straws were held vertically for 1 min without shaking and were then placed horizontally for 5 min to dilute the cryoprotectants.
