Microwave resonant absorption of SARS-CoV-2 viruses.

Low power microwave can effectively deactivate influenza type A virus through the nonthermal structure-resonant energy transfer effect, at a frequency matching the confined-acoustic dipolar mode frequency of the virus. Currently, aerosol is considered the major route for SARS-CoV-2 transmission. For the potential microwave-based sterilization, the microwave-resonant frequency of SARS-CoV-2 must be unraveled.

Resonant Dipolar Coupling of Microwaves with Confined Acoustic Vibrations in a Rod-shaped Virus.

In this letter, we treat a rod-shaped virus as a free homogenous nanorod and identify its confined acoustic vibration modes that can cause strong resonant microwave absorption through electric dipolar excitation with a core-shell charge distribution. They are found to be the n = 4N-2 modes of the longitudinal modes of the nanorods, where N is an integer starting from 1 and n is the mode order quantum number. This study was confirmed by measuring the microwave absorption spectra of white spot syndrome virus (WSSV), which is a rod-shaped virus.

Primary human immunodeficiency virus infection presenting as elevated aminotransferases.

Background/purpose: Primary human immunodeficiency virus type 1 (HIV-1) infection is often under-diagnosed because of its nonspecific presentations. Elevated aminotransferase levels is one of its clinical manifestations, but is infrequently reported in the literature. The objective of this study was to investigate cases of elevated aminotransferases as a manifestation of primary HIV-1 infection.

Clinical manifestations of Japanese encephalitis in southern Taiwan.

Background And Purpose: Japanese encephalitis virus infection is a sporadic infectious disease in Taiwan. Despite progress in laboratory examinations and imaging studies, diagnosis of Japanese encephalitis remains underestimated. This study was conducted to identify clinical symptoms and laboratory findings that may assist in early identification of this disease.

Comparison of clinical characteristics of amebic liver abscess in human immunodeficiency virus (HIV)-infected and non-HIV-infected patients.

Background And Purpose: Amebic liver abscess is an emerging parasitic disease in human immunodeficiency virus (HIV)-infected patients. Clinical characteristics of this disease have rarely been compared between patients with and without HIV infection.

Methods: This retrospective study included 24 patients who had been diagnosed with amebic liver abscess during a 17-year period.
