The effect of triacylglycerol (TAG) compositions and physical properties related to solid fat content (SFC) on the behavior of granular crystal formation was investigated. Four fat blends involving different 1,3-dipalmitoyl-2-oleoylsn-glycerol (POP) and 1-palmitoyl-2,3-dioleoyl-sn-glycerol (POO) compositions or SFC were prepared, and crystallization was investigated using polarizing microscopy, X-ray diffraction, SFC, whereas hardness was determined using a texture analyzer. Samples containing a higher saturated fattyacid content from palm and higher SFC showed higher β-type crystals in the initial period, yielding a number of small-sized crystals, with no growth occurring afterward. Growth of the granular crystals as a function of time was observed in the samples, transforming from the β'to β-type polymorph gradually. Large granular crystals at the initial stage were observed in the sample with a higher POO content and lowest SFC. These results suggested that POO promotes the rate of the crystals' polymorphic transformation, resulting in the growth of granular crystals. In contrast, excess high-meltingpoint TAG content, such as tripalmitin and POP, retarded granular crystal growth regardless of the increased β' to β transition rate. We concluded that the behavior of the growth of granular crystals is influenced by the combined effect of TAG composition and SFC.
Using the olfactory placode of 12.5-and 14.5-day-old (E12.5, E14.5) rat embryos, we examined the migration of LHRH neurons by in vivo intraventricular transplantation and in vitro organotypic culture systems. In the transplantation, the olfactory placode of E12.5 embryos was co-transplanted with the cerebral cortex and also with medial basal hypothalamus (MBH). LHRH neurons that had migrated into the co-trans
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
