TL;DR: In this paper, the transesterification reaction of rapeseed oil in supercritical methanol was investigated without using any catalyst, and it was shown that in a preheating temperature of 350°C, 240 s of supercritical treatment of methenol was sufficient to convert the rapeseed oils to methyl esters.

TL;DR: In this article, the authors found that homozygous mutant embryos have severely impaired placentas with markedly reduced numbers of labyrinthine trophoblast cells, and die before birth, suggesting that HGF/SF is an essential mediator of mesenchyme-trophoblastic epithelia interaction required for placental organogenesis.
Abstract: HEPATOCYTE growth factor/scatter factor (HGF/SF) functions as a mitogen, motogen and morphogen for a variety of cultured cells1–7. The genes for HGF/SF and its receptor (the c-met protooncogene product8) are expressed in many tissues during the embryonic periods and in the adult9–14. HGF/SF is thought to mediate a signal exchange between the mesenchyme and epithelia during mouse development15. To examine the physiological role of HGF/SF, we generated mutant mice with a targeted disruption of the HGF/SF gene. Here we report that homozygous mutant embryos have severely impaired placentas with markedly reduced numbers of labyrinthine trophoblast cells, and die before birth. The growth of trophoblast cells was stimulated by HGF/SF in vitro, and the HGF/SF activity was released by allantois in primary culture of normal but not mutant embryos. These findings suggest that HGF/SF is an essential mediator of allantoic mesenchyme-trophoblastic epithelia interaction required for placental organogenesis.

TL;DR: It is shown that ECs relied on glycolysis rather than on oxidative phosphorylation for ATP production and that loss of the gly colytic activator PFKFB3 in ECs impaired vessel formation.

TL;DR: An artificial crystal structure has been fabricated exhibiting a full three-dimensional photonic bandgap effect at optical communication wavelengths, encouraging us to create an ultra-small optical integrated circuit including a three- dimensional photonic crystal waveguide with a sharp bend.
Abstract: An artificial crystal structure has been fabricated exhibiting a full three-dimensional photonic bandgap effect at optical communication wavelengths. The photonic crystal was constructed by stacking 0.7-micrometer period semiconductor stripes with the accuracy of 30 nanometers by advanced wafer-fusion technique. A bandgap effect of more than 40 decibels (which corresponds to 99.99% reflection) was successfully achieved. The result encourages us to create an ultra-small optical integrated circuit including a three-dimensional photonic crystal waveguide with a sharp bend.

TL;DR: The water permeability of biological membranes has been a longstanding problem in physiology, but the proteins responsible for this remained unknown until discovery of the aquaporin 1 (AQP1) water channel protein.
Abstract: The water permeability of biological membranes has been a longstanding problem in physiology, but the proteins responsible for this remained unknown until discovery of the aquaporin 1 (AQP1) water channel protein. AQP1 is selectively permeated by water driven by osmotic gradients. The atomic structure of human AQP1 has recently been defined. Each subunit of the tetramer contains an individual aqueous pore that permits single-file passage of water molecules but interrupts the hydrogen bonding needed for passage of protons. At least 10 mammalian aquaporins have been identified, and these are selectively permeated by water (aquaporins) or water plus glycerol (aquaglyceroporins). The sites of expression coincide closely with the clinical phenotypes--ranging from congenital cataracts to nephrogenic diabetes insipidus. More than 200 members of the aquaporin family have been found in plants, microbials, invertebrates and vertebrates, and their importance to the physiology of these organisms is being uncovered.
