Gender and racial diversity Assumed by text-to-image generators in microsurgery and plastic surgery-related subspecialities.

Background: Since the release of ChatGPT by OpenAI in November 2022, generative artificial intelligence (AI) models have attracted significant attention in various fields, including surgery. These advancements have been particularly notable for creating highly detailed and contextually accurate images from textual prompts. A notable area of clinical application is the representation of surgeon demographics in various specialties, particularly in the context of microsurgery and plastic surgery-related subspecialties.

Patient-Centric Approach to Personalized Electronic Medical Records via QR Code in Japan.

Government policies in the United States and the European Union promote standardization and value creation in the use of FAIR (findability, accessibility, interoperability, and reusability) data, which can enhance trust in digital health systems and is crucial for their success. Trust is built through elements such as FAIR data access, interoperability, and improved communication, which are essential for fostering innovation in digital health technologies. This Viewpoint aims to report on exploratory research demonstrating the feasibility of testing a patient-centric data flow model facilitating semantic interoperability on precision medical information.

Experimental method for creating skin with acquired appendage dysfunction.

Mammalian skin appendages, such as hair follicles and sweat glands, are essential for both esthetic and functional purposes. Conditions such as burns and ulcers can lead to dysfunction or loss of skin appendages and result in hair loss and dry skin, posing challenges in their regeneration. Existing animal models are insufficient for studying acquired dysfunction of skin appendages without underlying genetic causes.

Molecular basis for the diversification of lincosamide biosynthesis by pyridoxal phosphate-dependent enzymes.

The biosynthesis of the lincosamide antibiotics lincomycin A and celesticetin involves the pyridoxal-5'-phosphate (PLP)-dependent enzymes LmbF and CcbF, which are responsible for bifurcation of the biosynthetic pathways. Despite recognizing the same S-glycosyl-L-cysteine structure of the substrates, LmbF catalyses thiol formation through β-elimination, whereas CcbF produces S-acetaldehyde through decarboxylation-coupled oxidative deamination. The structural basis for the diversification mechanism remains largely unexplored.
