Abstract: The present disclosure provides diving goggles, which include: a mask assembly, including a mounting hole, and a dismounting hole passing through a side wall of the mounting hole; a lens, installed in the mounting hole; a pressing ring, detachably embedded in one end of the mounting hole to fix the lens, the dismounting hole facing an outer peripheral wall of the pressing ring; and a detaching component, mounted on the mask assembly, one end of the detaching component passing through the dismounting hole and resisting against the outer peripheral wall of the pressing ring, for detaching the pressing ring from the mounting hole.

Abstract: The present invention relates to the use of temperature protective agents to protect temperature sensitive vaccines. Such agents can be used to protect vaccines from degradation that results from exposure to freezing conditions or hot environments. Such agents can also be used to help reduce or prevent degradation or contamination in reconstituted vaccines. The temperature protective agent may include glycerin, polyethylene glycol or propylene glycol.

Abstract: Methods for generating an immune response at a mucosal surface are described. Compositions suitable for use in the methods for generating an immune response at a mucosal surface are also described. In addition, methods for treating or preventing a disease caused by the entry of a pathogen into the body of a subject via a mucosal surface are provided.

Abstract: A protein from M. catarrhalis, designated the 74 kD protein, is isolated and purified. The 74 kD protein has an amino-terminal amino acid sequence which is conserved among various strains of M. catarrhalis. The protein has a molecular weight of approximately 74.9 kD as measured on a 10% SDS-PAGE gel, while its molecular weight as measured by mass spectrometry is approximately 74 kD. The 74 kD protein is used to prepare a vaccine composition which elicits a protective immune response in a mammalian host, to protect the host against disease caused by M. catarrhalis.
