Abstract: Anti-Epstein Barr Virus (EBV) vaccines are described herein. The EBV vaccine antigens are linked to a multimerization domain, for example, presented on a circular tandem repeat protein (cTRP) scaffold or linked to a C4b multimerization domain. The vaccines can be used to treat and/or reduce the risk of EBV infection and to treat and/or reduce the risk of complications associated with EBV infection, such as infectious mononucleosis, lymphoproliferative disorders, carcinomas, and smooth muscle tumors.

Abstract: Sequential immunization strategies to guide the maturation of antibodies against the human immunodeficiency virus (HIV) are described. The sequential immunization strategies utilize an HIV envelope protein (Env) that binds germline (gl) B cells as a first (prime) immunization and an Env with a functional glycosylated N276 as a second (boost) immunization. The sequential immunization strategies successfully elicit neutralizing antibodies against HIV.

Abstract: The disclosure provides antibodies, antibody fragments, and antibody derivatives that bind to the viral envelope spike protein (S2P) of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), and related compositions, and methods. In some embodiments, the antibodies, antibody fragments, and antibody derivatives bind to an epitope of the receptor binding domain (RBD) of SARS-CoV-2.

Abstract: Anti-Epstein Barr Virus (EBV) antibodies and vaccines are described herein. The antibodies and vaccines can be used to treat and/or reduce the risk of EBV infection and to treat and/or reduce the risk of complications associated with EBV infection, such as infectious mononucleosis, lymphoproliferative disorders, carcinomas, and smooth muscle tumors.

Abstract: Engineered and multimerized human immunodeficiency virus (HIV) envelope glycoproteins are described. The envelope glycoproteins can be multimerized using a heptamerization domain such as a C4b binding protein multimerization domain or a ferritin fusion. The engineered and multimerized envelope glycoproteins can derived from glycoprotein 120 (gp120) and can used as an HIV vaccine.

Abstract: Devices and methods for measuring roller chain wear are provided. A roller chain wear gauge may include an elongated structure configured to be inserted into a gap between two roller links of a chain joined by a pin link of the chain, the chain having an associated chain size. The elongated structure may include a first side surface, a second side surface, a length extending along a longitudinal axis of the elongated structure, and a plurality of widths located along the length and defined by and between the first and second side surfaces. The first side surface may extend at an angle relative to the longitudinal axis such that the plurality of widths continuously tapers over the length. The plurality of widths may be calibrated against a reference chain representative of the associated chain size.
