Deep-water fauna attached to clinker.A, the anemone Phelliactis robusta, from 2311 m in the Eastern Whittard Canyon, SW Ireland, taken during cruise JC10, Dive 65, of the HERMES project (Photo courtesy of P. Tyler, Uni. Southampton, and D. Masson, NOCS/NERC); B, the brachiopod Gryphus vitreus attached to clinker and to a scaphopod shell (Photo courtesy of Ariadna Mechò, ICM-CSIC). (A) The gross findings of aneurysm 4 weeks after surgery. The surrounding tissue was dislocated by the aneurysm (black arrows) attached to common carotid artery (white arrows). (B) The cross-section view of aneurysm. There was a patent aneurysmal orifice (white arrow) in the aneurysm (black arrows). Gross specimen revealing a spherical, well-circumscribed tumor with a gelatinous cut surface. (A) Intraoperative removal of bullet fragment with a shodded pituitary rongeur through the working channel. (B) Intraoperative illustration of the size of the removed bullet fragment. Effect of hypoxia on MSC plasticity. Oil-Red-O stain of MSC in adipogenic induction medium at atmospheric and reduced oxygen concentrations after 14 days of culture: (A) 21% O2. control; (B) 21% O2. adipogenic induction; (C) 1% O2. control; (D) 1% O2. adipogenic induction. Alizarin Red-S staining for the deposition of calcium precipitates is an indicator for the osteogenic differentiation. Viability and osteogenic differentiation of MSC from most donors was drastically reduced in this medium under 1% O2 as compared to 21% O2: (E) 21% O2. control; (F) 21% O2. osteogenic induction; (G) 1% O2. control; (H) 1% O2. osteogenic induction. However, a slight increase of oxygen to 3% allowed for efficient differentiation of MSC into osteoblasts: (I) 3% O2. control; (J) 3% O2. osteogenic induction. Three independent experiments of adipogenic and osteogenic differentiation were performed.
Example of non-sensitivity of radiography. (a) Baseline sagittal intermediate-weighted fat-suppressed image shows normal articular cartilage coverage in the medial femur and tibia. (b) At 24-month follow-up, there is circumscribed thinning of cartilage in the posterior medial femur (arrows). (c) Baseline radiograph does not show any abnormalities in regard to joint space width or any definite osteophytes at the medial tibia (no arrow). (d) At 24-month follow-up, no change is observed in comparison with the baseline image. Joint formation appears normal at E17.5 in Apaf-1 mutants. (A) Trichrome stained section of incudomalleal joint at E17.5 in an Apaf-1 wildtype littermate. (B) Trichrome stained section of incudomalleal joint at E17.5 in an Apaf-1 homozygote mutant. (C) Skeletal preparation with alcian blue staining of Apaf-1 wildtype littermate. (D) Skeletal preparation with alcian blue staining of Apaf-1 homozygous mutant. No defect in shaping of the articulation is observed. M = malleus. I = Incus. Scale bar in (A) = 200 μm. Scale bar in (C) = 400 μm. Endoscopic approach to the left ethmoidal mucocele DNA localization in linked large-budded pcs1td cells at  37°C. (A) Nomarski image of cells. The numbers designate the  presumed order of budding, as explained in the text. (B) DNA  (DAPI). (C) Microtubules (FITC). Bar, 5 μm. A 41-year-old man with red eye, proptosis, chemosis, bruit and visual loss of the right eye (Case #1). (a) Cerebral angiography of the right internal carotid artery (ICA) confirmed high-flow direct carotid cavernous fistula with âvascular stealâ phenomenon. The cavernous sinus and superior ophthalmic vein (*) showed marked dilatation. (b) Under road mapping technique, two gold-valve balloons (B) were detached. (c) Immediate angiography after balloon embolization showed complete obliteration of the fistula, preserving the ICA lumen. (d) Cranial X-ray shows contrast-filled balloons. Patient
Photograph of the study site near the village of Saduase, Ga East District, Ghana. High quality figures are available online. Microscopic images of Plectropomus leopardus tissues; a) Scanning Electron Micrograph (SEM) of the healthy tissue; b) SEM of the lesion.MGCâ=âmucus goblet cells, Mâ=âmucus. c) Light microscope image of a healthy scale and d) light microscope image of a diseased scale, showing disorganisation of natural melanin patterns seen in (c). Scales barsâ=â10 µm. Transmission electronic micrographs of Cu(acac)2/TiO2 sample at different magnifications. (A) Ã200,000; (B) Ã250,000; (C and D) Ã600,000.

Mrs Eliakima Glazer and Dr Israel Glazer welcoming Mr Yitzhak Navon, President of the State of Israel, to the Convention Center. Recurrent purpuric and necrotic lesions on the amputation stumps with repeat use of cocaine.
Myocardial fibrosis and changes in left ventricular (LV) outflow tract gradient during exercise. (A) Patient with a large amount of myocardial fibrosis and modest increase in LV outflow tract gradient. (B) Patient with a limited amount of fibrosis and relevant increase in LV outflow tract gradient during exercise. High resolution phase and phalloidin rhodamine labeling show podosomal anomalies in osteopetrotic osteoclastsCells were grown on glass cover slips. The fields shown were taken with 40à objectives and all photographs are 220 µm across.A, C. Osteoclasts from the osteopetrotic patient. In phase contrast at high power (A) prominent cell membrane structures often occurred in broad regions of the cells (arrows). Phalloidin rhodamine labeling (C) showed very large clusters and bands of podosomes sometimes in peripheral bands and in some cases across the center of the cell attachment (arrows). These ringed some spaces (asterisk) but typically these were much smaller than the cell diameters, and highly variable. A and C are photographs of two similar fields.B, D. Control normal osteoclasts showing peripheral cell attachment structure. In contrast to osteopetrotic cells, normal osteoclasts have well defined borders in phase (B) that correspond to one or more regular and well defined peripheral rings of podosomes (Arrowheads, D). The cells shown in B and D are the same field. (a) PHASIX Mesh comprised of a fully resorbable polymer (poly-4-hydroxybutyrate, P4HB) monofilament knitted into a flat sheet configuration. (b) P4HB Plug comprised of a fully resorbable polymer (poly-4-hydroxybutyrate, P4HB) monofilament preformed into a three-dimensional shape with a fluted outer layer and inner layers or ââpetalsâ attached at the tip. Reduction of CSN5 alters neuronal development.(A) PNS dendritic arborization neurons in a non-mutant third instar larva, visualized by the 109(2)80-GAL4-driven expression of UAS-GFP.
