4Delayed presentation of a loose body in undisplaced paediatric talar neck fracture显示文摘Fractures of the talus are rare in children.A high index of suspicion is needed to avoid missing such an injury,which is not an uncommon occurrence especially with undisplaced fractures.We present an unusual case of an undisplaced talar neck fracture in a five-year-old child leading to a delayed presentation of a symptomatic osteochondral loose body in the ankle joint.To our knowledge there are no reports in the literature of osteochondral loose bodies occurring in conjunction with an associated undisplaced talar neck fracture in either children or adults.The loose body was removed using anterior ankle arthroscopy.The child had an uneventful post operative recovery and regained full range of movement and function of his ankle joint and was discharged at one year follow-up.We aim to highlight the need to have a low threshold to further evaluate symptomatic children after fracture healing of an undisplaced talar neck fracture for a possible associated loose bodyin the ankle joint.Vishal Patel Benjamin Bloch Nicholas Johnson Jitendra Mangwani 2014World Journal of Orthopedics2014,5,3:2

8MODELING COMMERCIAL PROCESSES AND CUSTOMER BEHAVIORS TO ESTIMATE THE DIFFUSION RATE OF NEW PRODUCTS显示文摘This paper presents a generic mathematical model for depicting the diffusion of an innovative product on a given market. Our approach relies on a probabilistic modeling of each customer behavior with respect to the commercial process which is used to promote such a product. We introduce in particular the concept of coherent market that corresponds to a market which can be analyzed in a uniform way within our model. This last notion allows us to recover the classical empirical results that were discovered and widely studied by E.M. Rogers and his school. We explain finally how to use our approach as a support for analytic predictive marketing.Alain BLOCH Daniel KROB Ada Suk-Fung NG 2005Journal of Systems Science and Systems Engineering2005,14,4:2
9Loss of Aβ-nerve endings associated with the Merkel cell-neurite complex in the lesional oral mucosa epithelium of lichen planus and hyperkeratosis显示文摘The Merkel cell-neurite complex initiates the perception of touch and mediates Ab slowly adapting type I responses.Lichen planus is a chronic inflammatory autoimmune disease with T-cell-mediated inflammation,whereas hyperkeratosis is characterized with or without epithelial dysplasia in the oral mucosa.To determine the effects of lichen planus and hyperkeratosis on the Merkel cell-neurite complex,healthy oral mucosal epithelium and lesional oral mucosal epithelium of lichen planus and hyperkeratosis patients were stained by immunohistochemistry(the avidin-biotin-peroxidase complex and double immunofluorescence methods)using pan cytokeratin,20(K20,a Merkel cell marker),and neurofilament 200(NF200,a myelinated Ab-and Ad-nerve fibre marker)antibodies.NF200-immunoreactive(ir)nerve fibres in healthy tissues and in the lesional oral mucosa epithelium of lichen planus and hyperkeratosis were counted and statistically analysed.In the healthy oral mucosa,K20-positive Merkel cells with and without close association to the intraepithelial NF200-ir nerve fibres were detected.In the lesional oral mucosa of lichen planus and hyperkeratosis patients,extremely rare NF200-ir nerve fibres were detected only in the lamina propria.Compared with healthy tissues,lichen planus and hyperkeratosis tissues had significantly decreased numbers of NF200-ir nerve fibres in the oral mucosal epithelium.Lichen planus and hyperkeratosis were associated with the absence of Ab-nerve endings in the oral mucosal epithelium.Thus,we conclude that mechanosensation mediated by the Merkel cell-neurite complex in the oral mucosal epithelium is impaired in lichen planus and hyperkeratosis.Daniela Calderon Carrion Yiiksel Korkmaz Britta Cho Marion Kopp Wilhelm Bloch Klaus Addicks Wilhelm Niedermeier 2016International Journal of Oral Science2016,8,1:2

11Direct observation of photonic Landau levels and helical edge states in strained honeycomb lattices显示文摘We report the realization of a synthetic magnetic field for photons and polaritons in a honeycomb lattice of coupled semiconductor micropillars.A strong synthetic field is induced in both the s and p orbital bands by engineering a uniaxial hopping gradient in the lattice,giving rise to the formation of Landau levels at the Dirac points.We provide direct evidence of the sublattice symmetry breaking of the lowest-order Landau level wavefunction,a distinctive feature of synthetic magnetic fields.Our realization implements helical edge states in the gap between n=0 and n=±1 Landau levels,experimentally demonstrating a novel way of engineering propagating edge states in photonic lattices.In light of recent advances in the enhancement of polariton–polariton nonlinearities,the Landau levels reported here are promising for the study of the interplay between pseudomagnetism and interactions in a photonic system.Omar Jamadi Elena Rozas Grazia Salerno Marijana Milicevic Tomoki Ozawa Isabelle Sagnes Aristide Lemaitre Luc Le Gratiet Abdelmounaim Harouri Iacopo Carusotto Jacqueline Bloch Alberto Amo 2020Light(Science & Applications)2020,9,1:2
