Development of a high-speed bioaerosol elimination system for treatment of indoor air.

We developed a high-speed filterless airflow multistage photocatalytic elbow aerosol removal system for the treatment of bioaerosols such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Human-generated bioaerosols that diffuse into indoor spaces are 1-10 μm in size, and their selective and rapid treatment can reduce the risk of SARS-CoV-2 infection. A high-speed airflow is necessary to treat large volumes of indoor air over a short period.

Proteomic analysis of the heart in normal aging mice.

Aging induces pathological cardiovascular changes such as cardiac dysfunction and arteriosclerosis. With aging, heart cells, especially, become more susceptible to lethal damage. In this report, we tried to understand the precise mechanism of myocardial change resulting from aging by examining the heart proteome in aging mice using two-dimensional gel electrophoresis (2DE).

Targeted delivery using immunoliposomes with a lipid-modified antibody-binding protein.

A recombinant antibody-binding protein originating from streptococcal protein G was modified with lipid in a site-directed manner by genetic engineering. The resulting lipoprotein was incorporated into the surface of liposomes by simple mixing. Immunoliposomes were then prepared by binding anti-IgG antibodies molecules onto the surface of proteoliposome via the lipid-anchored streptococcal protein G.
