is overexpressed in keloid keratinocytes and its inhibition alters profibrotic gene expression.

Background: Keloids are disfiguring, fibrotic scar-like lesions that are challenging to treat and commonly recur after therapy. A deeper understanding of the mechanisms driving keloid formation is necessary for the development of more effective therapies. Reduced vitamin D receptor (VDR) expression has been observed in keloids, implicating vitamin D signaling in keloid pathology.

Serum levels of total bile acids are associated with an increased risk of HCC in patients with cirrhosis.

Background: Previous studies have reported higher circulating bile acid levels in patients with HCC compared to healthy controls. However, the association between prediagnostic bile acid levels and HCC risk among patients with cirrhosis is unclear.

Methods: We measured total BA (TBA) concentration in serum samples collected from a prospective cohort of patients with cirrhosis who were followed until the development of HCC, death, or last study date.

represses short-wavelength cone genes to preserve long-wavelength cone and rod photoreceptor identity.

The role of transcription factors in photoreceptor gene regulation is fairly well understood, but knowledge of the cell-type-specific function of transcriptional cofactors remains incomplete. Here, we show that the transcriptional corepressor promotes rod differentiation and represses short-wavelength cone genes in long-wavelength cones in zebrafish. In retinas, red cones are transformed into hybrid red/ultraviolet (UV) cones, green cones are absent, the number of blue cones is approximately doubled, and the number of rods is greatly reduced.

Large-Language Models in Orthodontics: Assessing Reliability and Validity of ChatGPT in Pretreatment Patient Education.

Background: Patients seeking orthodontic treatment may use large language models (LLMs) such as Chat-GPT for self-education, thereby impacting their decision-making process. This study assesses the reliability and validity of Chat-GPT prompts aimed at informing patients about orthodontic side effects and examines patients' perceptions of this information.

Materials And Methods: To assess reliability, n = 28 individuals were asked to generate information from GPT-3.

Differences in Prediagnostic Serum Metabolomic and Lipidomic Profiles Between Cirrhosis Patients with and without Incident Hepatocellular Carcinoma.

Background: Early detection of hepatocellular carcinoma (HCC) is crucial for improving patient outcomes, but we lack robust clinical biomarkers. This study aimed to identify a metabolite and/or lipid panel for early HCC detection.

Methods: We developed a high-resolution liquid chromatography mass spectrometry (LC-MS)-based profiling platform and evaluated differences in the global metabolome and lipidome between 28 pre-diagnostic serum samples from patients with cirrhosis who subsequently developed HCC (cases) and 30 samples from patients with cirrhosis and no HCC (controls).
