Broad cross-protective anti-hemagglutination responses elicited by influenza microconsensus DNA vaccine.

Despite the routine development and distribution of seasonal influenza vaccines, influenza remains an important pathogen contributing to significant human morbidity as well as mortality each year. The seasonal variability of influenza creates a significant issue for vaccine development of seasonal strains that can afford protection from infection or disease based on serotype matching. It is appreciated that the globular head of the HA antigen contained in the vaccines generates antibodies that result in HAI activity that are a major correlates of the protection against a particular strain.

A Novel DNA Vaccine Platform Enhances Neo-antigen-like T Cell Responses against WT1 to Break Tolerance and Induce Anti-tumor Immunity.

Tumor-associated antigens have emerged as important immunotherapeutic targets in the fight against cancer. Germline tumor antigens, such as WT1, Wilms' tumor gene 1, are overexpressed in many human malignancies but have low expression in somatic tissues. Recent vaccination approaches to target WT1 have been hampered by poor in vivo immune potency, likely due to the conserved self-antigen nature of WT1.

DNA Vaccines: A Strategy for Developing Novel Multivalent TB Vaccines.

Multivalent DNA vaccines that are delivered by electroporation (EP) through muscle tissue provide a novel method for eliciting immunity against tuberculosis (TB) as well as a broad range of diseases including HIV and cancers. Proper plasmid construction containing suitable protective TB antigens capable of evoking desired vaccine-induced responses would lead to the appropriate induction of both humoral and cellular immunity. DNA vaccines are safe and of low cost in comparison to traditional vaccines while also providing potentially effective prophylactic or therapeutic modalities against currently untreatable diseases.

Protective immunity to H7N9 influenza viruses elicited by synthetic DNA vaccine.

Despite an intensive vaccine program influenza infections remain a major health problem, due to the viruses' ability to change its envelope glycoprotein hemagglutinin (HA), through shift and drift, permitting influenza to escape protection induced by current vaccines or natural immunity. Recently a new variant, H7N9, has emerged in China causing global concern. First, there have been more than 130 laboratory-confirmed human infections resulting in an alarmingly high death rate (32.

Value-based analysis of routine pathologic septal and inferior turbinate specimens.

Objective: To determine the frequency and clinical relevance of unanticipated histopathologic results in routine sinonasal surgery and evaluate the necessity for histologic processing of nasal septal cartilage, bone, and inferior turbinate specimens.

Study Design: Case series with chart review.

Setting: Tertiary care academic medical center.

Frontal sinus osteoma removal with the ultrasonic bone aspirator.

Osteomas, the most common skull tumors, are typically excised through either an open or endoscopic ostectomy using a high-speed drill, a technically challenging procedure that can result in injury to adjacent soft tissue structures. Osteoma removal through ultrasonic bone emulsification and aspiration (UBA) offers the advantages of decreased blood loss, preservation of adjacent soft tissue structures, and precise bone removal. UBA was used to successfully remove a forehead osteoma without injury to adjacent nerves and with a satisfactory cosmetic outcome.
