We demonstrate the fixed-volume droplet generator for (i) the formation of monodisperse droplets from a source of varying flow rates, (ii) the formation of monodisperse droplets containing a gradation of solute concentration, and (iii) the parallel production of monodisperse droplets.

“Background:

check details Autologous fat graft, by virtue of its volumetric qualities and its action on skin trophicity, can be considered as a gold standard implant. Current techniques do not allow very superficial or subdermal injections of adipose tissue. The authors report technical modifications that enable fat transfer through a 25-gauge cannula. The viability of grafted fat was assessed after subcutaneous injection on a murine model.\n\nMethods: Micro-fat grafting consists of harvesting fat tissue using a multiperforated cannula with holes of 1 mm. Fat tissue is refined as described LCL161 manufacturer by SR Coleman and transferred through a micro-cannula. Initially, human fat was first harvested using two different procedures: Coleman’s technique and the modified harvesting technique. Preliminary comparative

histologic analyses were performed. Sixteen nude mice received human fat tissue: one side was filled with 0.7 cc through a 17-G cannula using Coleman’s technique, and the opposite side was grafted using smaller cannulae (20G, 23G and 25G) following the modified harvesting technique. Mice were

euthanised at 12 weeks and skin biopsies were performed.\n\nResults: Experimental fat grafts on mice were observed and analysed: macroscopically, the fat tissue of each side showed the same healthy aspect. Haematoxylin-eosin-saffron staining revealed intact adipocytes and anti-CD31 antibody immunohistochemical staining highlighted an abundant neo-vessel network.\n\nConclusion: Fat graft obtained by the modified technique maintains a normal histologic structure. Fat injection with micro-cannulae extends the application of lipostructure to the superficial layers of the skin.

“Pteropods were identified from epipelagic net and trawl samples in the Sub-Antarctic Zone during the 2007 mid-summer (January 17-February 20) Sub-Antarctic Zone Sensitivity to Environmental Change (SAZ-Sense) voyage, as well as in a moored sediment trap in the same region. Overall pteropod densities during SAZ-Sense were lower than those reported for higher-latitude Southern Ocean waters. The four major contributors to the Sub-Antarctic Zone pteropod community during the SAZ-Sense voyage, Clio pyramidata forma antarctica, Clio recurva, Limacina helicina antarctica and Limacina retroversa australis, accounted for 93% of all pteropods observed. The distribution of the two dominant pteropods collected in the Sub-Antarctic Zone, L. retroversa australis and C.
