MATLAB code to track the liquid of a binary tif image stack

<div>This Matlab code (A_tracking.m) imports a tif image stack, which is binary, where the black pixels represent the liquid and should flow from the right side to the left. The distance in pixels is then recalculated to mm by either inserting a resolution of the images or defining how long the channel is in total. The slope of the squared traveled distance versus the time is calculated using the file slope.m. The code is written and tested in Matlab R2017a.</div><div>An example tif-file is uploaded (Example_D_G1_1_CIMG7473.tif), where the side channels are cut off (the channel has 75 junctions).<br></div

Diode laser to treat small oral vascular malformations: A prospective case series study

The current work examined a consecutive series of patients presenting vascular malformations (VMs) and venous lakes (VLs) of the lip and oral mucosa who were treated with transmucosal diode laser applications and assessed over a 1 year period. STUDY DESIGN AND METHODS: Fifty-nine patients (31 males and 28 females) presenting low-flow VMs or VLs of the oral cavity were treated transmucosally using a diode laser (with an 830 nm operating wavelength and 1.6 W output power) with a 320 µm diameter flexible fiber. All the lesions were assessed 7 days, 30 days, and 1 year after the laser treatment, and the lesion reduction percentage was scored on a one to five scale. The patients were also asked to assess their pain perception daily during the 7 days following the treatment using a visual analog scale (VAS). RESULTS: There were no procedure-related intra- or post-operative complications; only modest pain intensity was reported. Thirty days after the treatment, lesion reduction was described as excellent or good in 52 cases; it was fair or poor in 7. Six patients (F:M ratio 2:4) required a second diode laser application. At the 1 year follow-up, volume reduction was complete in 48 out of 59 patients; there were five recurrences (F:M ratio 3:2). No relevant gender-related differences were noted. CONCLUSION: The use of diode laser application to treat small oral VMs and VLs was associated to shorter operating times and fewer postoperative complications with respect to the scapel surgery approach. More than one session may nevertheless be required if the anomaly is larger than 10 mm

<i>GFAP</i> and <i>Vim</i> upregulation after ECL at the injured and contralesional side.

<p>(A) <i>GFAP</i> and (B) vimentin (<i>Vim</i>) mRNA is upregulated in the hippocampal tissue at the injured side (I) at both 4 and 14 days after injury and at the contralesional side (C) at day 4. U, uninjured control; * p<0.05; ** p<0.01; *** p<0.001.</p

<i>Ezr</i>, <i>Thbs4</i> and <i>Syt1</i> upregulation after ECL at the injured and contralesional side.

<p>(A) Ezrin (<i>Ezr</i>) and (B) thrombospondin 4 (<i>Thbs4</i>) mRNA is upregulated in hippocampal tissue at the injured (I) side at both 4 and 14 days after injury. (C) Synaptotagmin 1 (<i>Syt1</i>) mRNA is upregulated in the injured side at day 14. At the contralesional side (C) at day 4, all three genes show mRNA upregulation. <i>Ezr</i> and <i>Syt1</i> also show mRNA upregulation on the contralesional side at day 14. <i>Thbs4</i> mRNA levels in the hippocampal tissue on both the injured and contralesional side are lower in <i>GFAP^−/−Vim^−/−</i> mice compared to wild-type mice at 4 days after ECL. U, uninjured control; * p<0.05; ** p<0.01; *** p<0.001.</p

<i>Gap43</i> and <i>Syp</i> expression are unaffected by ECL.

<p>(A) Growth associated protein 43 (<i>Gap43</i>) and (B) synaptophysin (<i>Syp</i>) mRNA levels in hippocampal tissue remained unchanged at 4 and 14 days after injury. U, uninjured control; I, injured hippocampus; C, contralesional hippocampus.</p

Complement components C1q and C3 upregulation following ECL.

<p>(A) Complement component C1q (here represented by <i>C1q, C chain</i>) mRNA is upregulated in the hippocampal tissue at the injured side (I) at both 4 and 14 days after injury and (B) <i>C3</i> mRNA is upregulated at 4 days after injury. <i>C1q</i> is also upregulated at the contralesional side (C) at day 4. U, uninjured control; * p<0.05; ** p<0.01; *** p<0.001.</p
