Purpose: As generalist large language models (LLMs) become more commonplace, patients will inevitably increasingly turn to these tools instead of traditional search engines. Here, we evaluate publicly available LLM-based chatbots as tools for patient education through physician review of responses provided by Google, Bard, GPT-3.5 and GPT-4 to commonly searched queries about prevalent chronic health conditions in the United States.

Purpose: To characterize research productivity of ophthalmic plastic and reconstructive surgery (OPRS) fellows during residency.

Methods: A database was compiled of OPRS fellows listed on the American Society of Ophthalmic Plastic and Reconstructive Surgery (ASOPRS) Annual Fall Scientific Symposium program books who began their fellowship between 2012 and 2019. PubMed was searched for all publications published between July 1st of the year they began residency and September 30th of the year they began fellowship training.

Bacteria use two-component system (TCS) signaling pathways to sense and respond to peptides involved in host defense, quorum sensing and inter-bacterial warfare. However, little is known about the broad peptide-sensing capabilities of TCSs. In this study, we developed an Escherichia coli display method to characterize the effects of human antimicrobial peptides (AMPs) on the pathogenesis-regulating TCS PhoPQ of Salmonella Typhimurium with much higher throughput than previously possible.

Metabolic changes associated with tissue inflammation result in significant extracellular acidosis (EA). Within mucosal tissues, intestinal epithelial cells (IEC) have evolved adaptive strategies to cope with EA through the up-regulation of SLC26A3 to promote pH homeostasis. We hypothesized that EA significantly alters IEC gene expression as an adaptive mechanism to counteract inflammation.

Nutrient sensors and developmental timers are two classes of genes vital to the establishment of early development in the social soil bacterium Myxococcus xanthus. The products of these genes trigger and regulate the earliest events that drive the colony from a vegetative state to aggregates, which ultimately leads to the formation of fruiting bodies and the cellular differentiation of the individual cells. In order to more accurately identify the genes and pathways involved in the initiation of this multicellular developmental program in M.

Experiments on fifteen simulated keyboards with different key sizes and inter-key spacings are reported. It was found that the movement time on these keyboards was well described by the model of Drury (Drury and Hoffmann 1992). Minimum movement times occurred when the inter-key spacing was approximately equal to the finger pad size.
