Abstract
Diabetes is a major concern of our society as it affects one person out of 11 around the world. Elastic fiber alterations due to diabetes increase the stiffness of large arteries, but the structural effects of these alterations are poorly known. To address this issue, we used synchrotron X-ray microcomputed tomography with in-line phase contrast to image in three dimensions C57Bl6J (control) and db/db (diabetic) mice with a resolution of 650 nm/voxel and a field size of 1.3 mm3. Having previously shown in younger WT and db/db mouse cohorts that elastic lamellae contain an internal supporting lattice, here we show that in older db/db mice the elastic lamellae lose this scaffold. We coupled this label-free method with automated image analysis to demonstrate that the elastic lamellae from the arterial wall are structurally altered and become 11% smoother (286,665 measurements). This alteration suggests a link between the loss of the 3D lattice-like network and the waviness of the elastic lamellae. Therefore, waviness measurement appears to be a measurable elasticity indicator and the 3D lattice-like network appears to be at the origin of the existence of this waviness. Both could be suitable indicators of the overall elasticity of the aorta.

Abstract
Background: LRP-1 is a multifunctional scavenger receptor belonging to the LDLR family. Due to its capacity to control pericellular levels of various growth factors and proteases, LRP-1 plays a crucial role in membrane proteome dynamics, which appears decisive for tumor progression. Methods: LRP-1 involvement in a TNBC model was assessed using an RNA interference strategy in MDA-MB-231 cells. In vivo, tumorigenic and angiogenic effects of LRP-1-repressed cells were evaluated using an orthotopic xenograft model and two angiogenic assays (Matrigel® plugs, CAM). DCE-MRI, FMT, and IHC were used to complete a tumor longitudinal follow-up and obtain morphological and functional vascular information. In vitro, HUVECs’ angiogenic potential was evaluated using a tumor secretome, subjected to a proteomic analysis to highlight LRP-1-dependant signaling pathways. Results: LRP-1 repression in MDA-MB-231 tumors led to a 60% growth delay because of, inter alia, morphological and functional vascular differences, confirmed by angiogenic models. In vitro, the LRP-1-repressed cells secretome restrained HUVECs’ angiogenic capabilities. A proteomics analysis revealed that LRP-1 supports tumor growth and angiogenesis by regulating TGF-β signaling and plasminogen/plasmin system. Conclusions: LRP-1, by its wide spectrum of interactions, emerges as an important matricellular player in the control of cancer-signaling events such as angiogenesis, by supporting tumor vascular morphology and functionality.

Abstract
The arterial wall consists of three concentric layers: intima, media, and adventitia. Beyond their resident cells, these layers are characterized by an extracellular matrix (ECM), which provides both biochemical and mechanical support. Elastin, the major component of arterial ECM, is present in the medial layer and organized in concentric elastic lamellae that confer resilience to the wall. We explored the arterial wall structures from C57Bl6 (control), db/db (diabetic), and ApoE-/- (atherogenic) mice aged 3 months using synchrotron X-ray computed microtomography on fixed and unstained tissues with a large image field (8 mm3 ). This approach combined a good resolution (0.83 µm/voxel), large 3D imaging field. and an excellent signal to noise ratio conferred by phase-contrast imaging. We determined from 2D virtual slices that the thickness of intramural ECM structures was comparable between strains but automated image analysis of the 3D arterial volumes revealed a lattice-like network within concentric elastic lamellae. We hypothesize that this network could play a role in arterial mechanics. This work demonstrates that phase-contrast synchrotron X-ray computed microtomography is a powerful technique which to characterize unstained soft tissues.

Abstract
Melanoma is the most aggressive form of skin cancer and the most rapidly expanding cancer in terms of worldwide incidence. If primary cutaneous melanoma is mostly treated with a curative wide local excision, malignant melanoma has a poor prognosis and needs other therapeutic approaches. Angiogenesis is a normal physiological process essential in growth and development, but it also plays a crucial role in crossing from benign to advanced state in cancer. In melanoma progression, angiogenesis is widely involved during the vertical growth phase. Currently, no anti-angiogenic agents are efficient on their own, and combination of treatments will probably be the key to success. In the past, phenacetin was used as an analgesic to relieve pain, causing side effects at large dose and tumor-inducing in humans and animals. By contrast, Phenacetinum low-dilution is often used in skin febrile exanthema, patches profusely scattered on limbs, headache, or flushed face without side effects. Herein are described the in vitro, in vivo, and ex vivo anti-angiogenic and anti-tumoral potentials of Phenacetinum low-dilution in a B16F1 tumor model and endothelial cells. We demonstrate that low-diluted Phenacetinum inhibits in vivo tumor growth and tumor vascularization and thus increases the survival time of B16F1 melanoma induced-C57BL/6 mice. Moreover, Phenacetinum modulates the lung metastasis in a B16F10 induced model. Ex vivo and in vitro, we evidence that low-diluted Phenacetinum inhibits the migration and the recruitment of endothelial cells and leads to an imbalance in the pro-tumoral macrophages and to a structural malformation of the vascular network. All together these results demonstrate highly hopeful anti-tumoral, anti-metastatic, and anti-angiogenic effects of Phenacetinum low-dilution on melanoma. Continued studies are needed to preclinically validate Phenacetinum low-dilution as a complementary or therapeutic strategy for melanoma treatment.

Abstract
Angiogenesis is defined as the formation of new capillaries by sprouting from the pre-existing microvasculature. It occurs in physiological and pathological processes particularly in tumor growth and metastasis. α1, α2, α3, and α6 NC1 domains from type IV collagen were reported to inhibit tumor angiogenesis. We previously demonstrated that the α4 NC1 domain from type IV collagen, named Tetrastatin, inhibited tumor growth in a mouse melanoma model. The inhibitory activity was located in a 13 amino acid sequence named QS-13. In the present paper, we demonstrate that QS-13 decreases VEGF-induced-angiogenesis in vivo using the Matrigel plug model. Fluorescence molecular tomography allows the measurement of a 65% decrease in Matrigel plug angiogenesis following QS-13 administration. The results are confirmed by CD31 microvessel density analysis on Matrigel plug slices. QS-13 peptide decreases Human Umbilical Vein Endothelial Cells (HUVEC) migration and pseudotube formation in vitro. Relevant QS-13 conformations were obtained from molecular dynamics simulations and docking. A putative interaction of QS-13 with α5β1 integrin was investigated. The interaction was confirmed by affinity chromatography, solid phase assay, and surface plasmon resonance. QS-13 binding site on α5β1 integrin is located in close vicinity to the RGD binding site, as demonstrated by competition assays. Collectively, our results suggest that QS-13 exhibits a mighty anti-angiogenic activity that could be used in cancer treatment and other pathologies with excessive angiogenesis such as hemangioma, psoriasis or diabetes.

Abstract
Bullous pemphigoid (BP) is a cutaneous autoimmune disease, characterized by an inflammatory cascade leading to blister formation. Although macrophages were shown to participate in BP pathophysiology, their role in the blister formation process still needs to be investigated. We here addressed the influence of serum and blister fluid (BF) from patients with BP on the polarization status of macrophages with regards to the metalloproteinase-9 (MMP-9) expression. We demonstrated that several markers related to the alternatively activated macrophage phenotype (M2) including IL-10, TARC, arginase, TNFα, and IL-1RA were meaningfully increased in BF of patients with BP. We further showed that BF, but not serum from patients with BP, significantly induced the expression of CD163, CD206, and IL-10 in BP monocyte-derived macrophages (MDMs). Notably IL-10 was the only cytokine to be correlated to the reference clinical score, BP disease activity index (BPDAI), especially to the inflammatory BPDAI subscore evaluating urticarial and erythematous skin lesions (r = 0.57, p = 0.0004). We also found elevated levels of MMP-9 to M2-type macrophages ex vivo and highlighted the presence of CD163+ MMP-9+ macrophages histologically, at skin lesional site. Finally, we showed that methylprednisolone reduced MMP-9 levels in MDMs without modifying the other M2 markers. All together these results strongly support the presence of M2-phenotype macrophages with pro-inflammatory properties susceptible to favor blister formation in BP.

Abstract
Bone fragility and loss are a significant cause of morbidity in patients with cystic fibrosis (CF), and the lack of effective therapeutic options means that treatment is more often palliative rather than curative. A deeper understanding of the pathogenesis of CF-related bone disease (CFBD) is necessary to develop new therapies. Defective CF transmembrane conductance regulator (CFTR) protein and chronic inflammation in bone are important components of the CFBD development. The receptor activator of nuclear factor kappa-B ligand (RANKL) and osteoprotegerin (OPG) drive the regulation of bone turnover. To investigate their roles in CFBD, we evaluated the involvement of defective CFTR in their production level in CF primary human osteoblasts with and without inflammatory stimulation, in the presence or not of pharmacological correctors of the CFTR. No major difference in cell ultrastructure was noted between cultured CF and non-CF osteoblasts, but a delayed bone matrix mineralization was observed in CF osteoblasts. Strikingly, resting CF osteoblasts exhibited strong production of RANKL protein, which was highly localized at the cell membrane and was enhanced in TNF (TNF-α) or IL-17-stimulated conditions. Under TNF stimulation, a defective response in OPG production was observed in CF osteoblasts in contrast to the elevated OPG production of non-CF osteoblasts, leading to an elevated RANKL-to-OPG protein ratio in CF osteoblasts. Pharmacological inhibition of CFTR chloride channel conductance in non-CF osteoblasts replicated both the decreased OPG production and the enhanced RANKL-to-OPG ratio. Interestingly, using CFTR correctors such as C18, we significantly reduced the production of RANKL by CF osteoblasts, in both resting and TNF-stimulated conditions. In conclusion, the overexpression of RANKL and high membranous RANKL localization in osteoblasts are related to defective CFTR, and may worsen bone resorption, leading to bone loss in patients with CF. Targeting osteoblasts with CFTR correctors may represent an effective strategy to treat CFBD. Copyright © 2016 Pathological Society of Great Britain and Ireland. Published by John Wiley & Sons, Ltd.

Abstract
Staphylococcus aureus is one of the most frequently involved pathogens in bacterial infections such as skin abscess, pneumonia, endocarditis, osteomyelitis, and implant-associated infection. As for bone homeostasis, it is partly altered during infections by S. aureus by the induction of various responses from osteoblasts, which are the bone-forming cells responsible for extracellular matrix synthesis and its mineralization. Nevertheless, bone-forming cells are a heterogeneous population with different stages of maturation and the impact of the latter on their responses toward bacteria remains unclear. We describe the impact of S. aureus on two populations of human primary bone-forming cells (HPBCs) which have distinct maturation characteristics in both acute and persistent models of interaction. Cell maturation did not influence the internalization and survival of S. aureus inside bone-forming cells or the cell death related to the infection. By studying the expression of chemokines, cytokines, and osteoclastogenic regulators by HPBCs, we observed different profiles of chemokine expression according to the degree of cell maturation. However, there was no statistical difference in the amounts of proteins released by both populations in the presence of S. aureus compared to the non-infected counterparts. Our findings show that cell maturation does not impact the behavior of HPBCs infected with S. aureus and suggest that the role of bone-forming cells may not be pivotal for the inflammatory response in osteomyelitis.

Abstract
Subcellular localization of meta-tetra (hydroxyphenyl) chlorin (mTHPC) in HT29 human colon adenocarcinoma cells has been studied by means of fluorescence microscopy. The observed diffuse intracellular distribution of mTHPC fluorescence outside the nucleus indicates general staining of cellular organelles. No changes in dye fluorescence pattern are evident during and immediately after cell illumination. Alternatively, the changes in mTHPC fluorescence pattern are observed upon subsequent cell incubation, and are characterized by the appearance of distinct bright fluorescence zones. Reaching a maximum 1 h after illumination, modifications of the fluorescence pattern then gradually disappear in parallel with the formation of plasma membrane blebs, suggesting that cell necrotic lysis is taking place. Photosensitized damage to mitochondria and the Golgi apparatus has been studied using fluorescent probes 1 h after irradiation, the stage of extensive cytoplasm vacuolization, and reveal alterations of these organelles. Changes in the mTHPC fluorescence pattern and mTHPC photocytotoxicity, as measured by the MTT test 24 h after illumination, are inhibited by sodium azide, a singlet oxygen quencher.

Abstract
A tamoxifen-resistant cell line (MCF7TAM) was established from tamoxifen-sensitive MCF-7 human breast cancer cells expressing estrogen receptors. Though the resistant cell line grows in the presence of tamoxifen, estrogen receptors continue to be expressed at similar levels as in the parental cell line. However, estrogen receptors appeared to be altered in the resistant cell line since important discrepancies are observed between results obtained with ligand binding assays and immunoenzymatic assays, tending to show modifications of estrogen receptor ligand binding capacity. The intracellular distribution of tamoxifen in sensitive and resistant cell lines was investigated using fluorescence of eosin-tamoxifen ionic association. Fluorescence emission spectra of eosin, tamoxifen and eosin-tamoxifen complex (lambda(ex)=480 nm) were analyzed and the maximal fluorescence intensity found for the complex (lambda(em)=540 nm) was four times higher than that of eosin alone, while tamoxifen alone did not emit any fluorescence in this spectral range. In MCF-7 cells, tamoxifen was found to be mainly located surrounding the nucleus, although nuclear fluorescence intensity was significantly lower. No highly fluorescent granules were observed in the resistant cell lines as opposed to sensitive cells. Improvement of this fluorescence microscopy methodology could appear of interest, taking into account the complexity of tamoxifen resistance molecular pathways.

Abstract
The multidrug resistance (MDR) modulating activity of SDZ-PSC833 (PSC), a non-immunosuppressive cyclosporine analogue, was investigated and compared with cyclosporin A (CSA) in bone marrow clinical specimens from 45 patients with acute myeloid leukaemia (AML) taken at diagnosis, using double-labelling flow cytometry with simultaneous determination of P-glycoprotein (PGP) expression and intracellular daunorubicin fluorescence (IDF). On the basis of pre-clinical results in multidrug-resistant K562 leukaemic cells, concentrations leading to iso-effective complete restoration of IDF were used: 5 and 10 micromol/l, respectively for PSC and CSA. In the clinical specimens, PGP expression was correlated with a significant decrease in IDE PSC was found to be significantly more potent than CSA since it was found to induce a significant increase in IDF in a higher number of cases and to a higher extent than CSA. PGP-unrelated activity of PSC was also observed in specimens expressing no PGP but exhibiting low IDF, thus probably expressing alternative resistance mechanisms. The results confirm the potency of PSC as MDR-modulating agent in clinical AML specimens whose resistance pattern differed from that of highly resistant cell models and suggest that the activity of PSC is not limited to P-glycoprotein inhibition.

Abstract
Twenty anatomical specimens were carefully studied in order to establish a possible connection between the posterior interosseous nerve and the radial tunnel syndrome. Our results show that the posterior interosseous nerve distal to the supinator muscle may be compressed by various structures. These include the distal border of the supinator muscle, the ramifications of the anterior and posterior interosseous vessels, and the septum between the extensor carpi ulnaris and the extensor digitorum minimi. The posterior interosseous nerve is also stressed during passive supination (elongation and rotation), and during passive pronation (compression). This suggests that the interosseous nerve distal to the supinator muscle should be explored in radial tunnel compression syndromes.

Abstract
Sixteen scapho-trapezio-trapezoid arthrodeses were performed for Kienböck's disease. In ten cases, a prosthetic replacement of the lunate was inserted at the same time. Clinical results were good with regard to pain and fair with regard to grip strength which was improved by an average of 32%. In contrast, the arc of flexion-extension was 38% less than on the unoperated side. Long-term radiographic assessment showed the efficacy of the procedure in maintaining carpal height. Biomechanical observations and a review of poor results showed the limits of the method and the importance of correct positioning of the scaphoid. We concluded that triscaphe arthrodesis was a useful procedure for the treatment of Kienböck's disease in Decoulx's stage 3.

Abstract
Lipofibroma is a rare, benign nerve tumour corresponding to diffuse fibroadipose infiltration of the nerve, dissociating the fasciculi without invading them. The authors report a case of lipofibroma of the median nerve in a 32 year old man presenting with a soft swelling of the palmar surface of the thumb. Treatment consisted of intraneurodissection of the tumour arising exclusively from the medial collateral nerve of the thumb. With a follow-up of two years, there has been no recurrence of the tumour, but the patient has persistent decreased sensation of the ulnar half of the thumb pulp. The features of the lipofibroma and the therapeutic options are discussed in the light of the data reported in the literature.

Abstract
In the nude mouse, the congenital absence of T lymphocytes makes it possible to implant human nerve grafts without rejection or iatrogenic modifications (by immunosuppression) of human and murine tissues. Medial antebrachial cutaneous nerves were harvested from human cadavers 1-18 hours after death. These nerve grafts were implanted using different techniques in nude mice. All the grafts were macroscopically and microscopically revascularized 3 days after implantation. The modifications in time of this vascularization could be studied with precision through the use of repeated biopsies. The absence of human blood group antigens on the neovessel endothelium suggested a murine origin for angiogenesis. In situ DNA hybridizations with human and mouse DNA confirmed this origin. The topography of the revascularization (maximal in the perineurium and endoneurium) and the almost complete absence of human cells other than Schwann cells in the grafts at the peak of angiogenesis (26 days after grafting) suggested that Schwann cells had a determining role in graft vascularization. The irradiation of the nerve grafts with a dose of 30 grays before implantation did not modify significantly their histologic appearance compared to the control group, whereas an irradiation of 60 grays led to massive lesions. The neurotization of murine axons led to chimerical structures of normal histologic appearance, with vascularization similar to that observed in nonneurotized nerves. Through chimerism (human Schwann cells, murine vessels and axons) this model makes it possible to dissociate the respective role of the host and of the nerve graft in angiogenesis and suggests the existence of growth factors produced by the human Schwann cells.

Abstract
The correction of functional deficits of the hand after a brachial plexus lesion is difficult; treatment should be provided by a well-knit team of surgeons and therapists. The patient should be fully aware of the limitations of surgical treatment before surgery, and should be entrusted to the care of a physical therapist during the critical period of nerve regeneration after initial surgical treatment to ensure optimal results. This article presents therapeutic possibilities and discusses specific problems of tendon transfers in brachial plexus palsy.

Abstract
Microsurgical techniques are becoming increasingly important in the emergency treatment of hand trauma and in secondary reconstructive surgery. In the light of the current concern with financial feasibility, we thought it important to determine whether this surgery, sometimes wrongly described as being luxury surgery, is economically feasible. The cost of 40 reimplantations and revascularisations of the thumb treated in the context of work accidents was studied. Although the short-term cost of reimplantation is higher than that of amputation, in the long-term, a successful reimplantation constitutes a definite economy for society and justifies this type of specialist surgery.

Abstract
Twelve rabbit femoral arteries were clamped for one hour with a TKS2 clamp in order to confirm the atraumatic nature of the Tamai disposable clamp. After 15 or 30 minutes of revascularisation, the arteries were excised and studied by light microscopy and scanning electron microscopy. Temporary dilatation of the artery was observed after removal of the clamp, as the patency test was always positive. Light microscopy revealed parietal flattening without any cellular disorganisation and scanning electron microscopy revealed flattening of the endothelial cells without any tearing. On the basis of these favourable results, combined with the ease of use, we now use the Tamai clamp daily.

Abstract
Axonal regeneration across 64 median nerve grafts in 34 rabbits was studied histologically to determine the optimal conditions for nerve allografting. Axonal regeneration across allografts in cyclosporin A-treated animals was satisfactory, but it occurred more slowly and with more inflammation and fibrosis than in autografts. Without immunosuppression, fresh allografts were rejected. However, in immunocompetent hosts, allografts rendered less immunogenic by predegeneration were not rejected, and axonal regeneration occurred. The combination of cyclosporin A and nerve graft predegeneration produced the most substantial axonal regeneration, comparable to autografts. The observations suggest that nerve allograft survival may be optimally effected by cyclosporin A treatment coupled with reduction in the immunogenicity of the grafts, such as by predegeneration.

Abstract
Transtriquetral triquetro-lunate arthrodesis is an original technique for partial arthrodesis of the wrist. This operation is indicated in the treatment of certain forms of triquetro-lunate instability and represents a new approach to the treatment of Decoulx's stages I and II of Kienböck's disease. The incision is medial and limited. The use of a special trephine guided by a pine allows the extraction of a triquetro-lunate osteocartilaginous cylinder. A cancellous bone graft is then performed to fill in the loss of substance. This new, simple surgical procedure, but demanding in terms of its technique, should decrease the failure rate and should improve the chances of lunate revascularisation.

Abstract
The surgical treatment of "swan-neck" deformities secondary to mallet finger using Littler's technique (Spiral Oblique Retinacular Ligament) in a series of 35 cases, led to a complete correction of the PIP joint hyperextension in 95% of the cases and a correction of the DIP joint flexure in 70% of the cases. This active tenodesis restores the physiology of the extension of the PIP and DIP joints as far as the surgical technique has been strictly respected.

Abstract
The importance of anatomical reduction of articular fractures and early mobilisation of these severe forms of trauma which frequently damage the extensor apparatus (58% of cases, led us to propose direct miniaturised osteosynthesis as described by the Nancy-Strasbourg team. Of the 1,000 cases of osteosynthesis performed between 1978 and 1985, we selected 12 fractures of the MP joint, 38 fractures of the PIP joint and 10 fractures of the DIP joint, differentiated into 4 stages according to the condition of the skin and tendons and into 9 categories according to the anatomical type and the site of the fracture. Direct osteosynthesis (screw, bolt, pin) was used in every case. The clinical results were evaluated in terms of the Total Active Range of Movements, the local trophic state, the amount of pain and return to work, for each joint. When well conducted and with effective skin cover, this technique allows almost normal reconstruction in simple fractures and is valuable in more complex fractures by preserving sliding of the tendinous apparatus due to early mobilisation.

Abstract
An automated method is proposed for photographing a microsurgical field that avoids missed photographs and time-consuming manipulations. The basic principles applied to microscopic photography are briefly reviewed and instructions are provided for standardized, reproducible, high quality photographs. A limitation at present is that auto-focusing cameras have not yet been adapted for use with surgical microscopes. One type of microscope is discussed and details about the only camera system currently suitable for such a microscope are described.

Abstract
The most common type of gastric metastases secondary to carcinoma of the breast is the one showing a linitis plastica appearance. The roentgenologic aspect when performing an upper gastrointestinal examination with barium contrast is typical and allows the differential diagnosis with the primitive linitis. The linitis plastica type of metastatic breast carcinoma results from transmural infiltration of the stomach wall with initial deposit of tumor cells in the submucosal or subserosal regions. CT provide valuable information concerning the metastatic spread.

Abstract
We report a case of involvement of a finger flexor tendon by sarcoidosis. A review of twelve cases suggests that this is a rare manifestation of the illness that most often affects the finger extensors at the wrist. It tends to present in established sarcoidosis and is associated with a higher than usual incidence of polyarthritis. The main differential diagnosis would be tuberculous tenosynovitis. We suggest that a histological spectrum exists running from a predominantly cellular picture to one of fibrotic nodules, perhaps explaining previously described instances of pseudo-tumour. We would recommend tenosynovectomy in conjunction with corticosteroid therapy as the treatment of choice.
