First Report of as an Emerging Bacterial Pathogen of Farmed Nile Tilapia () in Brazil.

Brazil is one of the world's leading producers of Nile tilapia, . However, the industry faces a major challenge in terms of infectious diseases, as at least five new pathogens have been formally described in the last five years. species are Gram-negative anaerobic bacteria that are often described as fish pathogens causing Motile Aeromonas Septicemia (MAS).

The effects of post-frozen-thawed embryo transfer pregnancy on early fetal development.

Aim: Frozen-thawed embryo transfer (FET) has gained popularity as an assistive reproductive technology despite its increased risk of large-for-gestational-age offspring. This study aimed to analyze the effect of FET on fetal development, particularly the growth rate and estimated fetal weight (EFW) throughout pregnancy.

Methods: This was a single-center, retrospective study that examined 97 patients with FET conception and 477 patients with natural conception (NC) who underwent labor and delivery at our clinic between December 2015 and June 2019.

Occurrence and disease burden of respiratory syncytial virus and other respiratory pathogens in adults aged ≥65 years in community: A prospective cohort study in Japan.

Background: The frequency and clinical profile of respiratory syncytial virus (RSV)-acute respiratory disease (ARD) in older adults in Japan has not been well-characterized.

Methods: This was a multicenter prospective observational cohort study to evaluate the occurrence rate of ARD in 1000 older adult participants (≥65 years) for 52 weeks during the 2019 to 2020 season. A multiplex polymerase chain reaction panel was used for pathogen detection in nasopharyngeal swab from participants diagnosed with ARD.

Estradiol accelerates liver regeneration through estrogen receptor α.

We previously demonstrated that liver resection triggers estradiol production, which, in turn, induces the proliferation of hepatocytes to promote liver regeneration in mice. In this study, we demonstrated estradiol-induced estrogen receptor alpha (ERα) expression. To further explore the role of ERα in estradiol-mediated liver regeneration, in the present study, we confirmed impaired liver regeneration ability in ERα knockout mice.

Incidence of human papillomavirus contamination of transvaginal probes in Japan and possible contamination prevention strategy.

Purpose: To clarify the present status of human papillomavirus (HPV) contamination of transvaginal probes in Japan and propose a preventive method.

Methods: This study was performed at three institutes: a tertiary center, secondary hospital, and primary facility. To identify contamination rates, probes were disinfected and covered with probe covers and condoms; the cover was changed for each patient.
