First evidence of skelemin, a myosin-associated protein, in smooth muscle and its involvement in cell adhesion, and, The role of the cell cycle in cell type choice during mammalian development
… of cell-cell as well as cell-substrate adhesion. Time lapse video microscopy was used to analyze the role of the cell cycle in cell type choice during mammalian development. Discussed are methods employed to improve resolution for accurate analysis.

Liquid-on-liquid mixing for slide-based biological assays
… polytene chromosomes by a factor of 100 in time and concentration, when compared to standard coverslip techniques. Flow visualization experiments reveal the fluid motions in the thin aqueous layer. Using time-lapse video photography to monitor the evolution of a drop of colloidal dye in the …

Migration of human tympanic epithelium in health and disease
… membrane epithelium, using light microscopy and time-lapse video recordings. <br></br><br></br>The results show: (1) that the epithelial and fibroblast content can be determined in different layers of the whole tympanic membrane and that the close proximity and shared polarity between epithelium …

The Aerobic Metabolism and Behavior of the Burrow-dwelling Mantis Shrimp, HEMISQUILLA ENSIGERA CALIFORNIENSIS
… cycle and monitored on a 24-hour basis using a time-lapse video recorder. Infrared lamps were used for observations within the burrow and at night. Metabolic rates, as a function of oxygen tension, were measured in respirometry chambers using polarographic oxygen electrodes.</p> <p>This species …

The Role of Protein S-glutathionylation on Ca2+ Signaling in Cultured Aortic Endothelial Cells
… using the fluorescent Ca2+ indicator, fura-2 and time-lapse video microscopy. Low concentrations (50, 100 ¿¿M) of diamide reversibly increased spontaneous Ca2+ oscillations, whereas high concentrations (250, 500 ¿¿M) of diamide caused an immediate, synchronized Ca2+ oscillation in essentially all …

Data-driven photographic style using local transfer
… stylization, including reproducing the precise time-of-day where the lighting and atmosphere can make a landscape glow, and making a portrait style resemble that created by a renowned photographer. Given an already captured image, however, automatically achieving given styles is challenging. In …

ScreenTrack: Using Visual History for Self-tracking Computer Activities and Retrieving Working Context
People spend a significant amount of time using computers at work, at home, or school. Given users switch tasks and are frequently interrupted or distracted while working, reconstructing working context is inevitable. For example, users sometimes need to revisit an arbitrary task from the past to …

Migration of tumor cells and leukocytes in extracellular matrix : proteolytic and nonproteolytic strategies for overcoming tissue barriers
… dermis in vivo were used, in combination with time-lapse video-, confocal- or intravital multiphoton-microscopy, and computer-assisted cell tracking. Expression of proteases, including several MMPs, ADAMs, serine proteases and cathepsins, was shown by flow cytometry, Western blot, zymography, …

Regulation of airway epithelial cell migration by the cystic fibrosis transmembrane conductance regulator.
… migration was also assessed morphometrically. Time lapse video images were also captured during wound closure of airway epithelial cells to assess how cell migration occurs. Additionally, the dependence of airway epithelial cell migration on Cl- and HCO3 - transport was assessed using ion …

Superpixel Segmentation of Outdoor Webcams to Infer Scene Structure
… and computer graphics. Scene elementsΓÇÖ time-series brightness gives insight to their geometric orientation; and thus the 3-D structure of the overall scene. Previous works have studied the time-series brightness of individual pixels. However, there are limitations with this approach. …

Morphogenesis in the moss physcomitrella patens
… the development of moss protonema using time-lapse video microscopy. This has provided a detailed record of the time-course of development from spore germination to the production of gametophores. Detailed records of the growth of primary and secondary chloronema, the transition of …

Topological organization of the trigeminal system in the lamprey and restoration following axonal regeneration
… The results indicate that at the longer recovery times (12 and 16 weeks), experimental animals showed a topographic organization of the trigeminal system, particularly nVm, as in normal animals. Moreover, with increasing recovery times, experimental animals recovered trigeminal-evoked escape …

Controlled release of GLP-1 from affinity-based protein microspheres and quantitative analysis of the role of fiber length on phagocytosis and inflammatory response by macrophages
… macrophages with the fibers were analyzed by time-lapse video microscopy, to qualitatively describe attempted phagocytosis in real time, and by flow cytometry, to quantitatively measure attachment and internalization of fibers. Short fibers were observed to bind to macrophages, being …

Behavioural interactions and reasons for aggression between Australian magpies (Gymnorhina tibicen) and other birds in New Zealand
… other birds; juveniles in breeding groups sometimes supported adults but never initiated attacks. Magpies in non-breeding flocks were not seen attacking other birds, except harriers ( attacked in 17% of appearances). Thirty-eight nests of seven species were continuously monitored in rural areas …

Avian nest predation: relationships with landscape characteristics and influences on adult and nestling behavior.
… within a nest fledged over a shorter period of time. My results illustrate that understanding the impact of landscape composition on predation by different predators requires evaluating patterns at multiple landscape scales. In doing so, we are likely to improve our ability to ascertain the …
