Selective visualization of the septal collaterals (arrow) with a microcatheter (Quick cross, Spectranetics, USA). A fully assembled apparatus for measuring LIC with the artificial external glottic device (LICA): a resuscitation bag is connected to the AEGD.Connection part (A); Control part (B). LIC, lung insufflation capacity; AEGD, artificial external glottic device; LICA, LIC with AGED.
Bone marrow–derived progenitor cells (BM-PC) bind directly to platelets (Plt) at sites of blood vessel injury. Selective angiography of the superior mesenteric artery. Approximately 5 cm from the major branch a small bleeding infarction is visible. Also, a large connection between the superior mesenteric artery and the celiac trunk via the gastroduodenal artery is present. This connection is also feeding the small bleeding. Virion morphology of Tweety. Electron micrograph of mycobacteriophage Tweety particles. Scale bar, 100 nm.
39-year-old male with hemoptysis in right lower lobe.A. Bronchial angiography showed bleeding from right bronchial artery which originated from intercostobronchial trunk.B. After embolization with 2-Fr microcatheter, follow-up bronchial angiography showed no evidence of bleeding in right bronchial artery. SEM images after positively charged silver nanoparticles were sprayed onto the negatively charged e-beam pattern. About 0.7 μm thick lines were generated over a large area with doses as low as 50 nC/cm2, showing the feasibility of ultrafast patterning by electrostatic lithography. (A) Scale bar = 50 μm. (B) Scale bar = 10 μm. (Reprinted with permission from Reference [133]. Copyright 2006 AVS The Science & Technology Society.) CBsv microinjection induces first cell cycle lengthening and developmental disorders in sea urchin embryos. CBsv (1 μM final concentration) was microinjected before fertilization in sea urchin eggs. Pictures were then taken during cleavage of microinjected (a, c, and e) or control uninjected (b, d, and f) embryos. (a and b) At 140 min controls were in metaphase of the third cycle, whereas CBsv microinjected just initiated anaphase of the first cycle. (c and d) At 170 min, controls were at the 8-cell stage, and microinjected eggs at the 2-cell stage. (e) At 240 min, injected embryos displayed various numbers of blastomeres irregular in size, here six blastomeres, one large and five small. (f) At 205 min, control embryos formed micromeres. a, c, and e are successive pictures of the same microinjected embryo. Bar, 50 μm. Structural analysis of enamel sample by SEM, after 35 days of remineralization
Droplet vaporization observed via optical microscopy. The initial droplet size was 4.5 µm (left). The bubble size was 19.5 µm one second after vaporization (right). The scale bar is 30 µm. Fragments obtained from DNA amplification by PCR. Lines with the mark (+) correspond to positive amplifications of P. falciparum parasites from salivary glands. The last fragments to the right correspond to positive and negative controls. Effect of solTNFα on NSC survival.3 concentrations of solTNFα (0.1 µM, 1 µM and 10 µM) were added to freshly seeded NSC cultures. Cells were evaluated up to 24 hours for signs of cell death. No increase in cell death relative to untreated cultures was observed in the cultures treated with solTNFα. The images taken of the cells treated with 0.1 µM of solTNFα, are representative of data obtained for all concentrations and are shown at (A) 1 hour, (B) 4 hours and (C) 24 hours post cytokine treatment. (D) Untreated cells are shown at 24 hours for comparison. Electron micrographs showing streaming and disruption of irregular Z-lines, and the amorphous cores from individuals III-17 (A) and III-1 (B). Cerebral angiogram shows a left MCA-M1 occlusion (A), which was successfully recanalized with deployment of a self-expandable stent (B). Intraarterial infusion of tissue plasminogen activator (25 MG) and thrombectomy with the Concentric Merci Retriever failed to recanalize the occlusion. Arrows demonstrate the proximal and distal ends of the stent.
