Interferon alpha as the one of FDA recommended drugs for Hepatitis B virus (HBV) infection has many side effects. Targeting IFNα to the liver may be a strategy to increase its efficacy locally and may increase efficacy of IFNα-based therapy of HBV infection. We have prepared a novel liver-targeting fusion interferon (IFN-CSP) combining IFN α2b with plasmodium region I peptide and have revealed it may be an excellent candidate as a liver-targeting anti-HBV agent. In this study, we investigated the genotoxic and teratogenic effects of IFN-CSP...

A subset of C2/C3 pilon fractures, open pilon injuries, metaphyseal bone comminution, and those involving substantial soft tissue or vascular injury may be nonreconstructable. Such injuries are at risk of progress to nonunion and failing open reduction internal fixation (ORIF). The risk of infection, malunion, and nonunion is relatively high with such injury patterns. In such cases, tibiotalar arthrodesis is performed after ORIF fails as a salvage procedure. Overall, the literature agrees that all pilon fractures will develop posttraumatic osteoarthritis, and these patients are ultimately treated with an arthrodesis or in narrow population with total ankle arthroplasty...

Environmental or chemically induced stresses often trigger physiological responses that regulate intracellular pH. As such, the capacity to detect pH changes in real time and within live cells is of fundamental importance to essentially all aspects of biology. In this respect, pHluorin, a pH-sensitive variant of green fluorescent protein, has provided an invaluable tool to detect such responses. Here, we report the adaptation of pHluorin2 (PHL2), a substantially brighter variant of pHluorin, for use with the human fungal pathogen Candida albicans...

The patient was an 86-year-old woman with back pain after a fall. She had no neurological findings at the initial visit. Plain radiographs and magnetic resonance imaging (MRI) showed diffuse idiopathic skeletal hyperostosis (DISH) and a Th10 fracture. Two weeks later, she started gait exercise with immobilization by a rigid orthosis. Twenty-five days later, she presented with paralysis and numbness of her legs. Computed tomography (CT) showed anterior expansion in the vertebral body of Th10. MRI showed an intramedullary high-intensity area on T2-weighted images at the same level...

Here we provide methods for setting up standard crosses with Schizosaccharomyces pombe strains. All strain genotypes and pedigrees should be recorded in a laboratory strain book. Matings between two haploid strains of interest are induced on solid medium poor in nitrogen. Usually, sporulation agar (SPA) plates are preferred, but for difficult matings it is advisable to try several mating media in parallel because one medium might allow for more efficient mating. Protoplast fusion can be used to produce zygotes from sterile mutants that fail to mate...

BACKGROUND: Cervical stand-alone interbody cages have seen increasingly wider use over the plate-and-screw construct in single-level anterior cervical discectomy and fusion (ACDF) in the treatment of cervical disc herniation and degenerative spondylotic conditions. Despite positive clinical outcomes, the efficacy and safety of using these devices in contiguous multi-level ACDF, however, has remained controversial. CASE DESCRIPTION: This report discusses a burst fracture seen as a complication in multi-level cervical stand-alone cage use...

Aequorin is a Ca(2+)-binding photoprotein that is a complex of apoaequorin (apoAQ) and 2-peroxycoelenterazine. In this study, the fusion protein (ZZ-apoAQ) composed of the synthetic IgG-binding domain (ZZ domain) derived from Staphylococcus aureus protein A and apoAQ was expressed into the periplasmic space of Escherichia coli cells. ZZ-apoAQ was highly purified using Ni-chelate affinity chromatography followed by IgG affinity chromatography. ZZ-AQ was prepared from purified ZZ-apoAQ by incubation with coelenterazine and was characterized, including its luminescence properties...

BACKGROUND: The graft site morbidity following iliac crest harvesting is significant. To overcome this, different bone substitutes like coral dowels, solvent dissolved bovine/human bone substitutes, and carbon fiber/titanium cages have been used. This study was undertaken to assess the postoperative radiological fusion rates and symptom relief in patients who had Tutobone used as an interbody spacer compared to autologous bone graft (ABG), cages, surgibone and coral dowels. METHODS: This was a retrospective, observational study...

BACKGROUND: In multilevel degenerative conditions posterior approaches are often preferred, but anterior approaches provide comparable clinical results and better alignment. Anterior plating entails higher rates of soft tissue injuries and dysphagia, particularly in multilevel cases. This study evaluates efficacy and safety of zero-profile devices in three and four-level ACDF, analyzing patients' clinical and radiological long-term outcome. METHODS: We prospectively enrolled 24 patients with cervical spondylotic myeloradiculopathy (CSM), who underwent three and four-level ACDF with Zero-P device...

Bacterial biofilms form when bacteria adhere to a surface and produce an exopolysaccharide matrix ( Costerton Science 1999 , 284 , 1318 ; Davies Science 1998 , 280 , 295 ; Flemming Nat. Rev. Microbiol. 2010 , 8 , 623 ). Because biofilms are resistant to antibiotics, they are problematic in many aspects of human health and welfare, causing, for instance, persistent fouling of medical implants such as catheters and artificial joints ( Brunetto Chimia 2008 , 62 , 249 ). They are responsible for chronic infections in the lungs of cystic fibrosis patients and in open wounds, such as those associated with burns and diabetes...
