“…The quenching effect of electrolytes and the effect of hydrogen ion concentration are also factors which must be considered in the analysis of vitamins (28). Koff and Frederick (61) have shown that silicone lubricants serve as a nonfluorescing stopcock grease for these determinations. Johnson (53) and others have developed a rapid field test for the estimation of riboflavin, thiamine, and Ari-methylnicotinamide in urine.…”

INA review of fluorescent analysis as applied to inorganic material appearing in this journal in 1939 (117), several books devoted to this subject were mentioned. Some of these have been revised and serve as excellent references. Danckwortt's book (20) which is specifically concerned with analysis in ultraviolet light, was revised in 1940 and has appeared in this country in lithoprinted form. This contains 1583 references.Feigl (29) gives many fluorometric applications for organic as well as inorganic compounds. Radley and Grant (92) also have an enlarged third edition; Chapter 8 which is on inorganic analysis has 123 references. Texts dealing with colorimetric analysis almost invariably give a discussion of fluorometric techniques. Sandell (100) gives methods for several elements and the Snells (107) in Chapter 15 of their third edition cover some general principles and apparatus for fluorescent analysis. Because of the listing of thq fluorescent color of many substancesfor example, 2896 organic compounds-the analyst will be interested in DeMent's book ( 22); how'ever, the review' by Fonda (33) should be read in connection with this. From a theoretical standpoint the Cornell symposium papers on solid luminescent materials edited by Fonda and Seitz (84), and the paper by Kasha (55) are of interest.

Female Reproduction Characteristics in a Large-Scale Breeding Colony of Cynomolgus Monkeys (Macaca fascicularis)

et al. 2010

Abstract:We studied two mating systems for a large-scale breeding colony of cynomolgus monkeys: (i) a 3-day timed system that keeps one female and one male together in a cage for 3 days beginning 11 days after menstruation, and (ii) a 7-day timed system beginning 9 days after menstruation. Regardless of the mating system used, we propose a practical definition of an infertile female as one that does not become pregnant in up to six pairings. If we eliminate these animals from the breeding colony, the pregnancy rates would be 3.6 times higher. Eliminating infertile females from a breeding colony is important in order to save labor, time and cost and to maintain a healthy breeding colony.
