It is essential for the study of T-cell function and the improveditions. However, VSV-G–pseudotyped virions may cause ment of adoptive cell therapies to efficiently generate large transduction artifacts that must be carefully excluded. The populations of human primary T cells that reliably express VSV-G virions require 10to 100-fold higher concentrations foreign genes. This goal is achieved by ...

Recombinant papillomavirus-like particles have recently been shown to be highly effective for the prevention of papillomavirus infections and associated tumors, and a virus-like particle-based vaccine against the most prevalent HPV causing genital infection in humans will be developed in the near future. Another use of these virus-like particles may lie in gene therapy and DNA immunization. We ...

Magnetopneumography is the study of the remanent magnetism of foreign intrathoracic ferromagnetic particles after magnetization by an external magnetic field. Given knowledge of the magnetic characteristics of the inhaled particles, this highly sensitive and non-invasive technique allows the measurement of lung dust loads. Many groups of workers have been examined in this way, e.g. welders, coa...

The hepatitis B virus (HBV) envelope protein (S) self-assembles into subviral particles used as commercial vaccines against hepatitis B. These particles are excellent carriers for foreign epitopes, which can be inserted into the external hydrophilic loop or at the N- or C-terminal end of the HBV S protein. We show here that the N-terminal transmembrane domain (TMD) of HBV S can be replaced by t...

Hepatitis E virus (HEV) causes not only endemics via a fecal-oral route but also sporadic cases via zoonotic transmission or blood transfusion. HEV-like particles (HEV-LP) produced by using a baculovirus expression system are considered a candidate for mucosal vaccines for HEV infection. In this study, we attempted to produce a chimeric HEV-LP presenting various foreign epitopes on its surface....

With lymph node enlargement, the possibility of a malignant process such as metastatic carcinoma or lymphoma needs to be excluded. This report describes a 47 year old woman with inguinal lymph node enlargement initially suspicious for lymphoma. Fine needle aspiration findings favoured reactive hyperplasia, but a malignant process could not be excluded. The final histological diagnosis was a for...

Directly acting antivirals recently have become available for the treatment of hepatitis C virus (HCV) infection, but there is no prophylactic vaccine for HCV. In the present study, we took advantage of the properties of Japanese encephalitis virus (JEV) to develop antigens for use in a HCV vaccine. Notably, the surface-exposed JEV envelope protein is tolerant of inserted foreign epitopes, perm...

Clathrate hydrates are crystalline compounds composed of hydrogen-bonded water molecules that form polyhedral cavities and trap small guest molecules such as methane, carbon dioxide, cyclopentane (CP), and tetrahydrofuran (THF). Understanding the formation and dissociation of clathrate hydrates is of significant importance to addressing some global challenges such as greenhouse gas mitigation a...

Severe combined burn-blast injury is a great challenge to surgical teams due to its high mortality. It also results in unsightly traumatic tattoos. The aims of these case reports were to clarify the clinical characteristic of the dynamite explosion burn-blast facial injuries and discuss appropriate management of these patients. We report two patients suffering from facial burn-blast injury foll...

Genetic immunization is a novel form of vaccination in which transgenes are delivered into the host to produce the foreign protein within host cells. Although systemic immune responses have been relatively easy to induce by genetic immunization, the induction of regional and mucosal immunity has often been more challenging. To address the problem of eliciting mucosal immunity in the lung, we ut...
