The organ culture from the testes of newborn pigs able to produce the basic androgens such as testosterone, dehydroepiandrosterone, androstenedione and androstenediol has been obtained. CdCl2 administration to the rats in a dose of 0.055 mg/100 g of body weight and gonadectomy resulted in the development of two experimental models of hypogonadism. Autotransplantation of organ culture from the rat testes and xenotransplantation of the testes from newborn pigs to the rats with experimental hypogonadism provoked an increase in blood plasma testosterone for 1.5 and 3 months, respectively. Organ cultures from the testes of newborn pigs can be recommended for clinical purposes.

Background: Although recommended isolation periods for Coronavirus disease 2019 (COVID-19) have been shortened as the pandemic has subsided, prolonged Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) shedding remains common in immunocompromised patients. This study estimated the probability of viral clearance in these patients based on elapsed days and specific risk factors.

Methods: We prospectively enrolled immunocompromised patients with a confirmed COVID-19 diagnosis from January 2022 to May 2023 during the Omicron variant era.

Hepatocellular carcinoma (HCC) is accompanied by an altered gut microbiota but whether the latter contributes to carcinogenesis is unclear. Here we show that faecal microbiota transplantation (FMT) using stool samples from patients with HCC spontaneously initiate liver inflammation, fibrosis and dysplasia in wild-type mice, and accelerate disease progression in a mouse model of HCC. We find that HCC-FMT results in gut barrier injury and translocation of live bacteria to the liver.

Organoids are stem cell-derived three-dimensional tissue cultures composed of multiple cell types that recapitulate the morphology and functions of their in vivo counterparts. Organ-on-a-chip devices are tiny chips with interconnected wells and channels designed using a perfusion system and microfluidics to precisely mimic the in vivo physiology and mechanical forces experienced by cells in the body. These techniques have recently been used to reproduce the structure and function of organs in vitro and are expected to be promising alternatives for animal experiments in the future.

Background: Photodynamic therapy (PDT) and radiotherapy using ionizing radiation (IR) are promising options for organ-preserving treatment of bladder cancer (BCa). A combination therapy (IR+PDT) could be beneficial for BCa treatment.

Purpose: For PDT, we used the near-infrared photosensitizer tetrahydroporphyrin-tetratosylate (THPTS) showing high therapeutic efficacy.
