NK/T-cell lymphoma with rash and peripheral neuropathy as the first manifestation: a case report and literature review.

Background: Extranodal NK/T-cell lymphoma, nasal type (ENKTCL-NT), is a rare, aggressive subtype of non-Hodgkin lymphoma, and it usually presents as a destructive sinus mass that may attend epistaxis. However, ENKTCL-NT with the manifestation of peripheral neuropathy is pretty unusual.

Case Presentation: A 17-year-old Chinese patient presented with peripheral neuropathy and positive auto-antibodies.

[Progress in the Treatment of Adult Langerhans Cell Histiocytosis --Review].

Langerhans cell histiocytosis (LCH) is a rare proliferative disease dominated by the proliferation of Langerhans cells, which is inflammatory myeloid neoplasms. Its clinical manifestations are variable, occurring at any age and at any site, and it is rarer in adults than in children. The gold standard for diagnosis is histopathological biopsy.

Extrinsic Calibration of Multiple Two-Dimensional Laser Rangefinders Based on a Trihedron.

Multiple two-dimensional laser rangefinders (LRFs) are applied in many applications like mobile robotics, autonomous vehicles, and three-dimensional reconstruction. The extrinsic calibration between LRFs is the first step to perform data fusion and practical application. In this paper, we proposed a simple method to calibrate LRFs based on a corner composed of three mutually perpendicular planes.

Electrochemical synthesis of three-dimensional porous reduced graphene oxide film: Preparation and in vitro osteogenic activity evaluation.

In this study, three-dimensional reduced graphene oxide (3D-rGO) porous films were fabricated using a two-step electrochemical method, including an electrochemical deposition process for the self-assembly of GO and an electrochemical bubbling-based transfer. The morphology, physical properties, and phase composition of the 3D-rGO films were characterized, and the cellular bioactivities were evaluated using pre-osteoblasts (MC3T3-E1 cells). The attachment, proliferation and differentiation of the MC3T3-E1 cells on the 3D-rGO films was analyzed by scanning electron microscopy (SEM), Cell Counting Kit-8 (CCK-8) assays and live/dead cell staining, and alkaline phosphatase (ALP) activity assays, respectively.
