Fuji, a major apple cultivar in Korea, is susceptible to white rot. Apple white rot disease appears on the stem and fruit; the development of which deteriorates fruit quality, resulting in decreases in farmers' income. Thus, it is necessary to characterize molecular markers related to apple white rot resistance. In this study, we screened for differentially expressed genes between uninfected apple fruits and those infected with Botryosphaeria dothidea, the fungal pathogen that causes white rot. Antimicrobial tests suggest that a gene expression involved in the synthesis of the substance inhibiting the growth of B. dothidea in apples was induced by pathogen infection. We identified seven transcripts induced by the infection. The seven transcripts were homologous to genes encoding a flavonoid glucosyltransferase, a metallothionein-like protein, a senescence-induced protein, a chitinase, a wound-induced protein, and proteins of unknown function. These genes have functions related to responses to environmental stresses, including pathogen infections. Our results can be useful for the development of molecular markers for early detection of the disease or for use in breeding white rot-resistant cultivars.

During the coronavirus disease 2019 (COVID-19) pandemic, widened physical distance and social deprivation are being replaced with digital media use. The media’s social function has tremendously increased following the COVID-19 era and adolescents living in a media-saturated world are the most vulnerable subjects of all. Social media use can encourage risky behavior in adolescents. Posting videos related to risk behaviors on social media has been linked to jeopardizing not only mental health but also physical safety. Herein, we report a case of a 12-year-old boy who intravenously self-injected Lactobacilli drinking yogurt for the purpose of filming a video to post on social media. He was treated with antibiotics based on Lactobacilli sepsis that cured him without any complications. In order to reduce the risk-taking behavior of adolescents, social norms need to be straightened up, and the social responsibility of hosts is strongly recommended.

Abstract We report oliguric mannitol-induced acute kidney injury (AKI) early treated by continuous renal replacement therapy. A 70-year-old woman was admitted to the Department of Neurology with diagnosis of acute intracranial hemorrhage. Mannitol was infused for intracranial pressure control. At admission third day, urine output was abruptly decreased to 57 ml during first 6 hours and blood urea nitrogen (BUN) and serum creatinine was increased to 54.2 mg/dL and 5.3 mg/dL respectively. Plasma osmolality was 340 mOsm/kg and osmolar gap was 70. Mannitol was immediately withdrawn and continuous renal replacement therapy (CRRT) was performed to remove mannitol rapidly. Urine output was increased 6 hours later after continuous veno-veno hemodiafiltration (CVVHDF) start. BUN and creatinine was decreased to 21.4 and 1.2 mg/dL at admission ninth day. Mannitol can develop oliguric AKI and CRRT may be of more benefit than conventional hemodialysis in the case of increased intracranial pressure.
