Division of Gastroenterology and Hepatology, Department of Medicine, Taipei Veterans General Hospital, Taipei, Taiwan, ROC.

Hepatitis B virus (HBV) infection is regarded as a major health concern worldwide. In patients with chronic HBV infection, exhausted virus-specific CD8+ T cells, resulting from the activation of the programmed cell death protein 1 and programmed death ligand 1 axis, play a key role in the chronicity of infection. Functional cure for HBV, defined as the seroclearance of hepatitis B surface antigen (HBsAg), is viewed as the optimal goal of chronic HBV infection treatment because HBsAg loss is associated with a low risk of hepatocellular carcinoma and a relatively favorable prognosis.

Circular RNAs (circRNAs) are post-transcriptional regulators generated from backsplicing of pre-mRNAs of host genes. A major circRNA regulatory mechanism involves microRNA (miRNA) sequestering, relieving miRNA-blocked mRNAs for translation and functions. To investigate possible circRNA-host gene relationship, skeletal myogenesis is chosen as a study model for its developmental importance and for readily available muscle tissues from farm animals for studies at different myogenic stages.

Objectives: Urothelial carcinoma in situ (CIS) with early papillary formation is terminology sometimes used to suggest incipient high-grade papillary urothelial carcinoma (PUC) but may lead to confusion between true CIS and lateral flat spread of PUC.

Methods: It remains unclear how pathologists and urologists interpret this scenario, so a survey was circulated to 68 pathologists (group 1 = 28 academic genitourinary pathologists; group 2 = 17 pathologists with a self-reported genitourinary focus; group 3 = 23 pathologists self-reported as not genitourinary specialists) and 32 urologists.

Results: Regarding atypical urothelial lesions that appear mainly flat but contain possible papillae, group 3 was more likely to label this as CIS compared with groups 1 and 2 (35% for group 3 vs 13% for groups 1 and 2), while groups 1 and 2 more often adopted another descriptive diagnosis, such as "CIS with early papillary features" (38% for groups 1 and 2 vs 13% for group 3).

Background: The caries severity in childhood may predict caries conditions in the future and even in adulthood in caries risk models. Nevertheless, the rate of recurrent caries after treatment of severe early childhood caries is high and correlated with behavioural factors, rather than clinical indicators. Compliance with the caries control programme has been demonstrated to prevent root caries development in head and neck cancer patients, suggesting that compliance with treatment protocols is a more important key to bringing about successful outcomes than treatment protocols themselves.

Background: Induced pluripotent stem cell (iPSC) technology has emerged as a powerful tool for disease modeling, providing an innovative platform for investigating disease mechanisms. iPSC-derived organoids, including retinal organoids, offer patient-specific models that closely replicate in vivo cellular environments, making them ideal for studying retinal neurodegenerative diseases where retinal ganglion cells (RGCs) are impacted. N6-methyladenosine (m6A), a prevalent internal modification in eukaryotic mRNAs, plays a critical role in RNA metabolic processes such as splicing, stability, translation, and transport.
