H1N1 nanobody development and therapeutic efficacy verification in H1N1-challenged mice.

Influenza A virus causes numerous deaths and infections worldwide annually. Therefore, we have considered nanobodies as a potential treatment for patients with severe cases of influenza. We developed a nanobody that was expected to have protective efficacy against the A/California/04/2009 (CA/04; pandemic 2009 flu strain) and evaluated its therapeutic efficacy against CA/04 in mice experiments.

Assessment of the immune interference effects of multivalent vaccine for influenza epidemic strain in 2022-2023 and evaluation of its efficacy.

The various strains of influenza virus cause respiratory symptoms in humans every year and annual vaccinations are recommended. Due to its RNA-type genes and segmented state, it belongs to a virus that mutates frequently with antigenic drift and shift, giving rise to various strains. Each year, the World Health Organization identifies the epidemic strains and operates a global surveillance system to suggest the viral composition for the influenza vaccine.

Self-Assembled Nanostructures Presenting Repetitive Arrays of Subunit Antigens for Enhanced Immune Response.

Infectious diseases pose persistent threats to public health, demanding advanced vaccine technologies. Nanomaterial-based delivery systems offer promising solutions to enhance immunogenicity while minimizing reactogenicity. We introduce a self-assembled vaccine (SAV) platform employing antigen-polymer conjugates designed to facilitate robust immune responses.

Liver transplantation with donation after medical assistance in dying: Case series and systematic review of the literature.

Medical assistance in dying (MAiD) has been a legally approved practice in Canada since 2016. Only recently have patients undergoing MAiD also been considered as donors for liver transplantation (LT). This study aimed to evaluate a case series of LT outcomes for recipients with MAiD donors and was paired with a systematic literature review of studies assessing the efficacy of MAiD-associated liver donation.

A COVID-19 Vaccine for Dogs Prevents Reverse Zoonosis.

COVID-19 is caused by severe acute respiratory syndrome virus type 2 (SARS-CoV-2), which can infect both humans and animals. SARS-CoV-2 originated from bats and can affect various species capable of crossing the species barrier due to active mutation. Although reports on reverse zoonosis (human-to-animal transmission) of SARS-CoV-2 remain limited, reverse zoonosis has been reported in many species such as cats, tigers, minks, etc.

User perception of medical service robots in hospital wards: a cross-sectional study.

Backgruound: Recently, there have been various developments in medical service robots (MSRs). However, few studies have examined the perceptions of those who use it. The purpose of this study is to identify user perceptions of MSRs.

A Memory-Efficient Transmission Scheme for Multi-Homed Internet-of-Things (IoT) Devices.

Internet-of-things (IoT) is a wide spreading technique that enables intelligence to the everyday objects, however, IoT devices are limited in computation and memory space due to their small physical sizes. As a result, IoT applications generally connect to the remote cloud that provides high computation and large storage. To enhance this communication, some IoT devices are equipped with multiple networks, e.

Frequency- and spectrally-encoded confocal microscopy.

We describe a three-dimensional microscopy technique based on spectral and frequency encoding. The method employs a wavelength-swept laser to illuminate a specimen with a spectrally-dispersed line focus that sweeps over the specimen in time. The spatial information along each spectral line is further mapped into different modulation frequencies.

Spectrally encoded slit confocal microscopy using a wavelength-swept laser.

We present an implementation of spectrally encoded slit confocal microscopy. The method employs a rapid wavelength-swept laser as the light source and illuminates a specimen with a line focus that scans through the specimen as the wavelength sweeps. The reflected light from the specimen is imaged with a stationary line scan camera, in which the finite pixel height serves as a slit aperture.
