Abstract
Infectious diseases pose persistent threats to public health, demanding advanced vaccine technologies. Nanomaterial-based delivery systems offer promising solutions to enhance immunogenicity while minimizing reactogenicity. We introduce a self-assembled vaccine (SAV) platform employing antigen-polymer conjugates designed to facilitate robust immune responses. The SAVs exhibit efficient cellular uptake by dendritic cells (DCs) and macrophages, which are crucial players in the innate immune system. The high-density antigen presentation of this SAV platform enhances the affinity for DCs through multivalent recognition, significantly augmenting humoral immunity. SAV induced high levels of immunoglobulin G (IgG), IgG1, and IgG2a, suggesting that mature DCs efficiently induced B cell activation through multivalent antigen recognition. Universality was confirmed by applying it to respiratory viruses, showcasing its potential as a versatile vaccine platform. Furthermore, we have also demonstrated strong protection against influenza A virus infection with SAV containing hemagglutinin, which is used in influenza A virus subunit vaccines. The efficacy and adaptability of this nanostructured vaccine present potential utility in combating infectious diseases.

Abstract
Bilayer spherical polymersome based adjuvants promote the antigen cellular uptake into antigen-presenting cells. The administration of polymersome loading OVA and MPLA induce the secretion of cytokines by macrophage activation and elicit potent antigen-specific antibody responses.

Abstract
Powerful adjuvants to augment vaccine efficacy with a less immunogenic vaccine system are in great demand. In this study, a novel squalene-based cationic poly(amino acid) adjuvant (CASq) that elicits both cellular (Th1) and humoral (Th2) immune responses is developed. CASq is demonstrated to promote cellular uptake of viral antigen and stimulate macrophages, leading to active production of interleukin-12. Furthermore, co-administration of inactivated pdm H1N1 vaccine with CASq significantly increases the generation of antigen-specific antibodies and T cell immune responses in mice, as well as resulting in complete prevention of disease symptoms and protection against lethal infection.

Abstract
Highly pathogenic avian influenza virus (HPAIV) infections have occurred continuously and crossed the species barrier to humans, leading to fatalities. A polymerase chain reaction based molecular test is currently the most sensitive diagnostic tool for HPAIV; however, the results must be analyzed in centralized diagnosis systems by a trained individual. This requirement leads to delays in quarantine and isolation. To control the spread of HPAIV, rapid and accurate diagnostics suitable for field testing are needed, and the tests must facilitate a differential diagnosis between HPAIV and low pathogenic avian influenza virus (LPAIV), which undergo cleavage specifically by trypsin- or furin-like proteases, respectively. In this study, a differential avian influenza virus rapid test kit is developed and evaluated in vitro and using clinical specimens from HPAIV H5N1-infected animals. It is demonstrated that this rapid test kit provides highly sensitive and specific detection of HPAIV and LPAIV and is thus a useful field diagnostic tool for H5N1 HPAIV outbreaks and for rapid quarantine control of the disease.

Abstract
Flufenoxuron is an insect growth regulator which inhibits chitin (exoskeleton) biosynthesis in insect's body. Not much is known about its toxicity to human. This report describes three patients who developed worsening lactic acidosis and hypotension after ingestion of flufenoxuron-containing materials. Two of the three patients received continuous renal replacement therapy and survived. (Hong Kong j.emerg.med. 2014;21:181-184)
