High-quality antibody (Ab) production depends on the availability of immunologically relevant antigens. We present a potentially universal platform for generating soluble antigens from bacterial hosts, tailored to immunized animals for Ab production. A novel RNA-dependent chaperone, in which the target antigen is genetically fused with an RNA-interacting domain (RID) docking tag derived from the immunized host, promotes the solubility and robust folding of the target antigen. We selected the N-terminal tRNA-binding domain of lysyl-tRNA synthetase (LysRS) as the RID for fusion with viral proteins and demonstrated the expression of the RID fusion proteins in their soluble and native conformations; immunization predominantly elicited Ab responses to the target antigen, whereas the "self" RID tag remained non-immunogenic. Differential immunogenicity of the fusion proteins greatly enriched and simplified the screening of hybridoma clones of monoclonal antibodies (mAbs), enabling specific and sensitive serodiagnosis of MERS-CoV infection. Moreover, mAbs against the consensus influenza hemagglutinin stalk domain enabled a novel assay for trivalent seasonal influenza vaccines. The Fc-mediated effector function was demonstrated, which could be harnessed for the design of next-generation "universal" influenza vaccines. The non-immunogenic built-in antigen folding module tailored to a repertoire of immunized animal hosts will drive immunochemical diagnostics, therapeutics and designer vaccines.

It is now generally recognized that the extracellular matrix and cellular heterogeneity of the tumor microenvironment influences the cancer cells' ultimate fate. Therefore, strategies employed to examine mechanisms of drug resistance must take microenvironmental influences, as well as genetic mutations, into account. This review discusses three-dimensional (3D) in vitro model systems which incorporate microenvironmental influences to study mechanisms of drug resistance in breast cancer. These bioengineered models include spheroid-based models, biomaterial-based models such as polymeric scaffolds and hydrogels, and microfluidic chip-based models. buy Rapamycin The advantages of these model systems over traditionally studied two-dimensional tissue culture polystyrene are examined. Additionally, the applicability of such 3D models for studying the impact of tumor microenvironment signals on drug response and/or resistance is discussed. Finally, the potential of such models for use in the development of strategies to combat drug resistance and determine the most promising treatment regimen is explored. © 2020 Wiley Periodicals, Inc.AIM Dilatation of the aortic root (AR) after aortic valve surgery associated with ascending aorta replacement (AVS+AAR) is an important concern in long-term follow-up (FU). This study aimed to identify factors that may be associated with this late complication. MATERIAL AND METHODS Two-hundred-sixteen consecutive patients (150 males and 66 females) who underwent AVS+AAR from June 2009 to April 2018 at a single center were retrospectively analyzed. The mean trans-thoracic echocardiographic (TTE) FU was 44.9 ± 22.2 months. An increase of 10% in AR size compared to the pre-operative baseline was the outcome variable. The Student t-test or chi-square test was used as appropriate. For a survival analysis, a Kaplan-Meier curve was computed and a log-rank p-value was calculated. Cox's regression model was used to assess the predictive value of variables over time. A p-value 5 mm. Significant AR enlargement was observed in 30.8 % of the S group and 14.7 % of the L group (log-rank = 0.026). A difference of more than 5 mm between the aortic valve prosthesis and the vascular prosthesis protected against AR enlargement in the long-term FU (OR 12.31, P = 0.033), even after adjusting for age and sex (OR 00.32, P = 0.043). CONCLUSION According to our findings, a difference between the size of the aortic valve prosthesis and the vascular prosthesis of less than or equal to 5 mm was the only factor that increased the risk of AR enlargement after AVS+AAR in long-term FU.Magnetically controlled intramedullary lengthening nails (MCILN) have revolutionized the field of limb lengthening and deformity correction. buy Rapamycin They allow for accurate and precise distraction with excellent patient outcomes and satisfaction. Though potentially technically easier than external fixation, general deformity principles and bone and soft-tissue biology must be considered for successful use. MCILN can address deformities of a wide range of etiologies including congenital, posttraumatic, post-infectious, tumor, and many others with excellent healing rates and outcomes as well as better patient satisfaction and similar cost compared to external fixation. Of the approximately 10,000 MCILN that have been implanted (written communication, NuVasive, Inc., San Diego, California), about 749 cases have been reported in the published literature. Applications outside of deformity correction are on the rise, with new uses reported in reconstruction after tumor resection and acute trauma. This review of MCILN summarizes the history, recent advances, and results of MCILN treatment in a multitude of clinical applications.OBJECTIVES The aim of this study was to evaluate the effect of palliative care on the symptom level assessment and satisfaction of patients diagnosed with cancer. METHODS The study was carried out with 60 cancer patients who received service at a palliative care center (PCC) and 59 cancer patients who received general care services at a public hospital. The effect of the services provided at the 2 hospitals was evaluated using the Edmonton Symptom Assessment System and the European Organisation for Research and Treatment of Cancer In-patient Satisfaction with Care Questionnaire. The data were analyzed to determine number and percentage distributions, the significance of differences between 2 peers, and 2-way analysis of variance in repetitive measurements. RESULTS It was determined that the symptom severity of the PCC patients was greater. In a 1 week interval, greater improvement was observed in all of the symptoms of the patients who received general care, and the evaluation revealed a statistically significant difference between the hospitals in terms of fatigue, nausea, and dyspnea (p less then 0.
