Variation in reporter gene (GFP) expression among transgenic <i>Drosophila melanogaster</i> lines.

<p>Relative expression levels of GFP were normalized to the expression of ribosomal protein 49 (<b><i>rp49</i></b>). Expression folds are calculated by comparison to line Vg1aL3, which had the lowest detectable GFP expression. Error bars represent standard errors. Letters represent statistical differences.</p

The effect of FLASH knockdown on apoptosis was dependent on p53.

<p>(<b>A</b>) HT1080 cells were transfected with scrambled siRNA (siControl), FLASH siRNA (siFLASH) and p53 siRNA (siP53) or co-transfected with both FLASH siRNA and p53 siRNA for 48 hours. Apoptosis was then induced by incubation with 100 ng/ml FasL for an additional 4 hours. Immunoblotting using p53 antibodies showed that p53 was effectively knocked down with siP53 in the presence and absence of siFLASH. Upon stimulation with the FasL, the increase in apoptosis in cells lacking FLASH was abolished in cells depleted of both FLASH and p53. (<b>B</b>) The effect of DNA damage incurred by exposure to adriamycin on the relative intracellular level of p53 and p21. Two isogenic cell lines, HT1080 (wildtype p53) and HT1080-6TG (p53 mutant), were treated with 200 ng/ml adriamycin for the indicated times. The intracellular level of p53 and p21 was determined by immunoblotting. The level of p-Histone H2A.X (Ser139) was used to monitor the progressive DNA damage induced by adriamycin treatment. β-actin served as a loading control. (<b>C</b>) The wild type HT1080 and HT1080-6TG cells (p53 mutant) were transfected, as in panel B, with siRNA against FLASH and the scrambled siRNA (Con) for 72 hours. The intracellular levels of FLASH and MCL-1 were determined by immunoblotting. β-tubulin served as a loading control.</p

DataSheet1_Cinematic rendering improves the AO/OTA classification of distal femur fractures compared to volume rendering: a retrospective single-center study.PDF

Purpose: Correctly classifying distal femur fractures is essential for surgical treatment planning and patient prognosis. This study assesses the potential of Cinematic Rendering (CR) in classifying these fractures, emphasizing its reported ability to produce more realistic images than Volume Rendering (VR).Methods: Data from 88 consecutive patients with distal femoral fractures collected between July 2013 and July 2020 were included. Two orthopedic surgeons independently evaluated the fractures using CR and VR. The inter-rater and intra-rater agreement was evaluated by using the Cicchetti-Allison weighted Kappa method. Accuracy, precision, recall, and F1 score were also calculated. Diagnostic confidence scores (DCSs) for both imaging methods were compared using chi-square or Fisher’s exact tests.Results: CR reconstruction yielded excellent inter-observer (Kappa = 0.989) and intra-observer (Kappa = 0.992) agreement, outperforming VR (Kappa = 0.941 and 0.905, respectively). While metrics like accuracy, precision, recall, and F1 scores were higher for CR, the difference was not statistically significant (p > 0.05). However, DCAs significantly favored CR (p Conclusion: CR offers a superior visualization of distal femur fractures than VR. It enhances fracture classification accuracy and bolsters diagnostic confidence. The high inter- and intra-observer agreement underscores its reliability, suggesting its potential clinical importance.</p

siRNA silencing of FLASH expression.

<p>(<b>A</b>) HT1080 cells were transfected with FLASH siRNA and scrambled siRNA (Control) (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0032971#s2" target="_blank"><i>Materials and Methods</i></a>). After 72 hours, the extracts of the transfected cells were analyzed by immunoblotting using FLASH antibodies and as a loading control, β-tubulin antibodies. (<b>B</b>) HT1080 cells were transfected with either a scrambled siRNA (left, Control) or a specific siRNA directed against FLASH (right). The cells were fixed with cold methanol for 10 minutes after 72 hours transfection, blocked, and incubated with rabbit anti-FLASH and mouse anti-PML at 4°C overnight. After washing three times, the cells were incubated with the secondary antibodies as described in the legend to <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0032971#pone-0032971-g003" target="_blank">Figure 3</a>. The cell nucleus was stained with Hoechst 33342. (<b>C</b>) Flow cytometry analysis showed that after FLASH knockdown, cells were blocked in S phase. HT1080 cells were transfected with siRNA against FLASH or scrambled RNAi for 72 hours. The cells were trypsinized, washed with cold PBS, fixed with 70% ethanol, treated with RNase A and stained with 50 µg/ml propidium iodide. The DNA content was analyzed using a Becton-Dickinson FACScan cytofluorometer.</p

Effect of FLASH knockdown on the level of anti-apoptotic proteins.

<p>(<b>A</b>) HT1080 cells were transfected with 3 different FLASH siRNAs for 72 hours. Coilin and the scrambled siRNA served as controls. The intracellular level of FLASH, coilin, MCL-1, histone H3 and the long and short isoforms of cFLIP, cFLIP (L) and cFLIP (S), respectively, were determined by immunoblotting using the corresponding antibodies. β-tubulin served as a loading control. (<b>B</b>) Following the same protocol, MCF-10A cells were transfected with siRNA directed against FLASH or with control siRNA. Cell extracts were prepared 72 hours following transfection and the cell lyates were subjected to immunoblotting using antibodies directed against the indicated proteins.</p

In Situ Formation of Tungsten Nitride among Porous Carbon Polyhedra for High Performance Zinc–Iodine Batteries

To address the low capacity and poor stability of aqueous zinc–iodine batteries owing to the insulating nature of iodine and the shuttle effect of polyiodide, herein, tungsten nitride-modified porous carbon polyhedron (W2N/N-C) was prepared via the pyrolysis of ZIF-8 injected with phosphotungstic acid (PTA@ZIF-8). During the thermal treatment process, the self-nitridation enabled the in situ formation of tungsten nitride nanoparticles in hierarchical porous carbon with nitrogen doping for favorable loading of iodine. When used as the electrode material, the zinc–iodine battery exhibited the low polarization during the charge/discharge process with improved reversibility and good cycling stability for 2000 cycles. The improved electrochemical performance would be attributed to the confinement effect of W2N/N-C for the reversible conversion between iodine and polyiodide, thus enhancing the redox reversibility and utilization of active materials. The present work demonstrates an efficient strategy to prepare porous carbon with metal nitrides via the combination of carbonization and self-nitridation process for high-performing zinc–iodine battery
