A sensing methodology that combines Au, tobacco mosaic virus (TMV), and folic acid for selective, sensitive, and colorimetric detection of tumor cells based on the peroxidase-like activity was reported in this study. Gold nanowires with a high aspect ratio were synthesized using TMV as a template. Au@TMV nanowire (AT) complex was obtained with diameter of 4 nm and length between 200 and 300 nm. In addition, since TMV was biocompatible and had many amino and carboxyl groups on its surface, AT was conjugated by folate to form a folic acid (FA)-conjugated AT composite (ATF) and tested by FTIR measurements. Furthermore, the peroxidase-like properties were studied and the optimal conditions for mimic enzyme activity were optimized. Finally, HeLa and other tumor cells expressed excessive receptors of folate on the surface, which can specifically bind to folic acid. As the specific binding of ATF with HeLa cells, the peroxidase properties of ATF were used for detection of cancer cells (Scheme 1). The cancer cells were detected not only qualitatively but also quantitatively. In this study, as low as 2000 cancer cells/mL could be detected using the current method.Dupilumab is a monoclonal antibody that binds to the common alpha chain of the IL‑4 and IL-13 receptor and blocks the Th2 signaling pathway, which plays a key role in the development of atopic dermatitis. We report on the case of a 40-year-old man, who developed histologically confirmed psoriasis after 6 weeks of dupilumab therapy. The arbitrary, abrupt stopping of the unusual, not guideline-based oral steroid therapy, together with the blockade of the Th2 signaling pathway by dupilumab were apparently the relevant trigger factors for the newly developed psoriasis in our patient.OBJECTIVE Minimally invasive posterior segmental instrumentation and intra-articular fusion with the Facet Wedge device. INDICATIONS All fusion indications in degenerative disc disease without significant translational instability, postnucleotomy syndrome, spondylarthrosis, discitis. CONTRAINDICATIONS Translatory instabilities, status after decompression with partial facet joint resection, spondylolysis in the affected segment. SURGICAL TECHNIQUE Through a 3 cm skin incision, blunt transmuscular approach to the corresponding facet joint L1/2 to L5/S1. Opening of the joint capsule and visualisation of the intra-articular space. Cartilage removal and intra-articular implantation of the Facet Wedge device. Fixation of the implant by means of two angle-stable screws inserted in the corresponding facet joint parts. POSTOPERATIVE MANAGEMENT Early mobilisation under thomboprophylaxis. Wearing a trunk-stabilizing brace for up to 12 weeks, depending on the type and extent of the procedure. No restrictions regarding walking distance, standing and sitting immediately postoperatively after pain. RESULTS In all, 27 patients (mean age 51.2 years, range 30-76 years) were enrolled in the prospective nonrandomized study from 02/2015 to 9/2017 with a total of 31 treated segments. In 23 cases a ventrodorsal surgical technique was used, in 4 cases a purely dorsal procedure with interposition of an intervertebral cage. Follow-up was 2 years. The Oswestry Score (ODI) improved from an average of 40.6% preoperatively to 16.6% postoperatively. The visual analog scale (VAS) for back pain improved from an average of 6.7 points preoperatively to 2.1 points 2 years postoperatively. During this observation period, 2 implant-specific complications were observed. One Facet Wedge had to be revised due to misplacement with early loosening. In another case, loss of correction occurred in a preoperatively existing first-degree spondylolisthesis with revision to a dorsal screw-rod system.OBJECTIVE Minimally invasive anterolateral approach to the lumbar spine (oblique lateral interbody fusion, OLIF) to correct lumb
