Soybean meal triggers neutrophil migration to the intestine after two days of feeding.Tg(mpx:GFP) transgenic larvae were analyzed in vivo by confocal microscopy to monitor neutrophil infiltration into the intestine at day 0 (A–C), 2 (E–G) and 4 (I–K) of feeding with control (pellet) and experimental diets (100FM diet and50SBM diet). (D, H, L) The number of intestine-infiltrated neutrophils was quantified by immunohistochemistry in the same larvae analyzed by confocal microscopy (inset). The results indicated that fish meal did not activate the immune response after 2 or 4 days of feeding. In the case of soybean meal, the number of infiltrated neutrophils was increased from day 2. Five larvae per condition in three different experiments were analyzed per time point by confocal microscopy. For immunohistochemistry analysis, at least 15 larvae per condition per time point in three different experiments were performed. Statistical analysis was conducted using one-way ANOVA. **p value < 0.01; ***pvalue < 0.001.
Optical sectioning and examination of Huh7-GFP xenografted larvae. Larvae (ache+/? and ache−/−) injected with Huh7-GFP cells were stained with GFP primary antibody and Cy3 tagged secondary antibody, and counterstained with DAPI and examined histologically by optical sectioning using a Zeiss LSM 880 confocal microscope. (a–f) At 20× magnification, z-stacks at 10 micron intervals were obtained and consecutive images were Z-projected to obtain these 2D images by maximum intensity projection in ImageJ. Tumor masses can be clearly seen in both images in red. (a’–f’) Same larvae were counterstained with DAPI for marking nuclei. (a”–f”) Merged images were presented.

Gross morphology and histological images of benign radiofrequency ablation (RFA) region. The areas represented from peripherial to central ablation are as follows: normal hepatocyte (N); reaction zone (RZ); ablation region (AR). (A–C) (on day 3 after RFA): Ablation lesion was shown as well circumscribed, gray-white tissue in gross morphology observation (A), in which AR and RZ cannot be distinguished obviously. 40× H&E histology (B) showed AH was dominated by coagulation necrosis. RZ was observed at the periphery of AR, mainly consisted by injury reaction (Inj) and inflammatory (Inf). 200× H&E histology (C) showed that Inj was mainly composed of hepatocytes with pyknosis and karyorrhexis, and Inf was manifested as small amount of inflammatory cell infiltration. (D–F) (on day 7 after RFA): Gross morphology image (D): granulation tissue around the ablation lesion can be observed (white arrows); 40× (E) H&E histology showed the change of RZ, in which Inj shrank while the inflammatory (Inf) and fibrosis increase, and a fibrous rim (FR) had formed in periphery. (F) showed Inj and Inf in 200× H&E histology. (G–I) (on day 14 after RFA): Gross morphology image of day 14 after RFA (G): granulation tissue around the ablation lesion had gotten thicker and denser (white arrows); 40× (H) and 200× (I) H&E histology showed Inj and Inf were significantly reduced and even disappeared in some area, RZ was mainly composed by a further thickened FR.
Hematoxylin and eosin staining of the graft. (a), (b), (c) After 7 days, skin grafts in Groups A and B had formed microvessels, the three-dimensional morphology of the scaffold was loosely structured and cell distribution was uniform; conversely, the Group C scaffold was clear. (d), (e), (f) After 14 days, the newly formed vessels in Group A were significantly increased with relatively fewer in Group B. Scaffolds in Group A and B were full of uniformly distributed cells, with varying degrees of degradation and absorption. Subcutaneous tissue cells tended to migrate into the Group C scaffold material, but numbers remained limited. (g), (h), (i) After 21 days, new blood vessels with uniform distribution could be found within the full layer of Group A, and these vessels were large and abundant. Vascularization in Group B was different from that in Group A, with only a few blood vessels formed at the junctions between the subcutaneous tissue and scaffold in Group C. Scale bars: 100 μm.

UNC-34 localizes to the leading edge of cell protrusions and to apical junctions.(A and A′) Confocal projections of dorsolateral (A) and ventrolateral (A′) surfaces (anterior is to the left) of the same embryo stained at mid-enclosure with anti-UNC-34 show broad expression throughout the embryo with enrichment at apical epidermal junctions.(B–E) Time-lapse sequence of projected confocal Z series, visualizing UNC-34::GFP in the ventral leading cell region (anterior is to the left) during enclosure. Besides apical junction enrichment, UNC-34::GFP is also present at the leading edge (arrowheads) of leading cell protrusions (C). Junctions enriched in UNC-34::GFP become apparent along the anterior and posterior borders of migrating cells ([C], arrow). Protrusions in contralateral partners meet at the ventral midline ([D], arrow), where apical junctions enriched with UNC-34::GFP eventually form ([E], arrow).(F–H) Confocal images of a wild-type 3-fold stage embryo expressing UNC-34::GFP (F) costained for AJM-1 (G). A merged image is shown in (H).(I–K) Representative wide-field images of wild-type (I), ajm-1(ok160) (J), and hmr-1(zu389) maternal and zygotic loss (K) embryos expressing UNC-34::GFP.

Images obtained from a 58-year-old female diagnosed with LABC HER-2 breast cancer who presented pCR after mastectomy. The ΔADC% increase between MR1 and MR2 was 54% (true positive to early prediction of NCT). No size change (false negative at this point) was observed after the first cycle of treatment. Because of its high restriction signal in diffusion, the patient was diagnosed with partial radiological response by DCE and DWI at MR3 (both false negative at this point). (A) Axial DWI at MR1 shows an extensive area with high signal intensity, denoting diffusion restriction. (B) Axial DWI at MR2 shows high signal intensity at the same site as shown in (A). (C) Axial DWI at MR3 shows a significant reduction in the area of diffusion restriction and high signal intensity at the tumor site. (D) Hematoxylin and eosin staining of a histological section of the mastectomy product after NCT. Residual disease is absent, while stromal fibrosis and vascular neoformation are observed, compatible with response to treatment (10x magnification).

Imaging of PP2-A1:GFP in sieve elements undergoing differentiation.Fluorescent PP2-A1:GFP protein observed in leaves of pSEOR2:PP2-A1:GFP plants. Images were obtained by CLSM. GFP fluorescence is shown in false color green, propidium iodide in nuclei is shown in red and plastid autofluorescence in magenta except in (e). (a) General overview of a main vein showing mature and immature sieve elements. (b) Immature sieve element with soluble PP2-A1:GFP. In this cell, a number of subcellular compartments, including organelles and the nucleus, are still present. (c) Immature sieve element with soluble PP2-A1:GFP, in which the nucleus is no longer observed, although plastid autofluorescence is still present. Arrows indicate plastids in an immature sieve element. (d) In some cells that have begun to differentiate, PP2-A1:GFP fluorescence aggregates around small organelles. As sieve elements mature, their organelles gradually disappear. PP2-A1:GFP is present in an aggregated form around organelles, presumably mitochondria, although still present in a soluble form in the cytosol. Arrows indicate dense PP2-A1 material, presumably around mitochondria and plastids. (e) In sieve element ongoing differentiation, PP2-A1:GFP fluorescence, shown in green, aggregates around mitochondria stained with MitoTracker (shown in red). Arrows indicate mitochondria. (f) In mature sieve elements, PP2-A1:GFP is present only attached to organelles. * indicates nuclei. Se: sieve element; i-se: immature sieve element; companion cell. Scale bar = 5 μm.
Additional examples of axonal microdomain disruption are apparent immediately adjacent to microinfarcts. Elongated and irregular contactin-associated protein (caspr)-positive paranodes (green) are frequently seen (A). In tissue adjacent to, but some distance from the infarct core (300–350 µm away from infarct core), axonal microdomains remain disrupted with irregular morphology of paranodal regions [inset (B)]. In some instances, Ankyrin-G (Ank-G)-positive axon initial segments can be identified [arrowheads, insets (C,D)]. Inset: magnification ×60, scale bar = 5 µm.
(A and B) Patient 4 had adenocarcinoma of pancreatic body, as well as hepatic, peripancreatic lymph node, and osseous metastases, which demonstrated high FAP expression on maximum-intensity-projection 68Ga-FAP-2286 PET image (A) and transverse 68Ga-FAP-2286 PET/CT image (B). (C and D) Significant uptake and late retention of 177Lu-FAP-2286 were noted in liver metastases on posttherapeutic whole-body scintigraphy in anterior and posterior views at 48 h after injection (C) and on transverse SPECT/CT image (D). Because of low resolution of 177Lu for imaging, as compared with 68Ga for PET/CT, not all tumor sites seen on 68Ga-FAP-2286 PET/CT are apparent on 177Lu-FAP-2286 images.
