Figure Legend Snippet: A schematic overview of the procedures used to produce the data in B-D. C. elegans are washed from NGM culture plates into a 1.5 mL tube and washed 3 times to remove residual debris and bacteria and to enrich for young adult worms. Worms are then mixed with liquid PF-127 and quickly added to the devices to allow for polymerization of the hydrogel. Initial experiments used 24-well devices with 3 slices, and later experiments used the gustatory microplate. Cues and controls are added as liquid bubbles to the top and bottom of the polymer, and then devices are incubated in a humid chamber to allow for worm gustation and burrowing. (B) C. elegans are attracted to either 100 mM or 200 mM NaCl, with a slightly higher CI when the cue was added to the top of the well. (C) Three-layer Stacks devices were separated after 1 hr. incubation, and worms in each slice were counted. Wild type (N2) worms are attracted to 200 mM NaCl and repelled by 10 mM quinine. tax-4(p678) worms show no response to NaCl and are attracted to quinine. (D) Chemotaxis indices of five chemosensory-defective knockout strains of C. elegans in response to 200 mM NaCl and 10 mM quinine. In each figure, dots represent the value for a single well of the device, large red dots represent the mean, and error bars represent the confidence limits. ***: p <= 0.001, ****: p <= 0.0001.
Techniques Used: Incubation, Chemotaxis Assay, Knock-Out
Figure Legend Snippet: (A) A schematic overview of the procedures used to produce the data in B. L3s were extracted from mosquitoes and washed 3 times prior to being mixed with liquid PF-127 and added to devices to allow for polymerization. Cues and controls are added as liquid bubbles to the top and bottom of the polymer, and devices are incubated in a humid chamber to allow for worm gustation and burrowing. (B) L3s from Brugia pahangi are attracted to FBS. Two methods for calculating chemotaxis index are shown. Dots represent the CI for a single well of the device, large red dots represent the mean, and error bars represent the confidence limits. *: p <= 0.05.

Article Snippet: _____________________________________________________________________ Background: Our earlier studies demonstrated that topically applied substance P (SP) or curcumin on excision skin wound accelerated the wound healing in streptozotocininduced diabetic rats.. In the present study, we aimed to evaluate the wound healing potential of combination of SP and curcumin in diabetic rats.. Materials and methods: Open cutaneous excision wound was created on the back of each of the sixty diabetic rats. |
