The Performance of ChatGPT on the American Society for Surgery of the Hand Self-Assessment Examination.

Background: This study aims to compare the performance of ChatGPT-3.5 (GPT-3.5) and ChatGPT-4 (GPT-4) on the American Society for Surgery of the Hand (ASSH) Self-Assessment Examination (SAE) to determine their potential as educational tools.

Diagnosis and Management of Lunotriquetral Ligament Injuries.

Purpose Of Review: The standard of care for lunotriquetral ligament injuries is evolving. An understanding of the mechanics of the lunotriquetral ligament and its role in carpal kinematics is critical when deciding how to treat these injuries. Treatment for these injuries varies from nonoperative to wrist arthroscopy with thermal capsulodesis and/or repair to reconstruction or limited arthrodesis.

Thermodynamics of hydrophobic-polar model proteins on the face-centered cubic lattice.

The HP model, a coarse-grained protein representation with only hydrophobic (H) and polar (P) amino acids, has already been extensively studied on the simple cubic (SC) lattice. However, this geometry severely restricts possible bond angles, and a simple improvement is to instead use the face-centered cubic (fcc) lattice. In this paper, the density of states and ground state energies are calculated for several benchmark HP sequences on the fcc lattice using the replica-exchange Wang-Landau algorithm and a powerful set of Monte Carlo trial moves.

Observed Altruism in Dental Students: An Experiment Using the Ultimatum Game.

The conventional wisdom in dental and medical education is that dental and medical students experience "ethical erosion" over the duration of dental and medical school. There is some evidence for this claim, but in the case of dental education the evidence consists entirely of survey research, which does not measure behavior. The aim of this study was to measure the altruistic behavior of dental students in order to fill the significant gap in knowledge of how students are disposed to behave, rather than how they are disposed to think.

Early Predictors of Mortality in Geriatric Patients With Trauma.

Objective: To identify variables that predict mortality in geriatric patients with trauma.

Design: Retrospective review.

Setting: Level I trauma center.

Chondroitin Sulfate is the Primary Receptor for a Peptide-Modified AAV That Targets Brain Vascular Endothelium In Vivo.

Recently, we described a peptide-modified AAV2 vector (AAV-GMN) containing a capsid-displayed peptide that directs in vivo brain vascular targeting and transduction when delivered intravenously. In this study, we sought to identify the receptor that mediates transduction by AAV-GMN. We found that AAV-GMN, but not AAV2, readily transduces the murine brain endothelial cell line bEnd.

Evaluating the side effects of treatment for preterm labor in a center that uses "high-dose" magnesium sulfate.

Objective: To evaluate the tolerability and safety of intravenous magnesium sulfate use for tocolysis in a center that uses a "high-dose" regimen.

Study Design: We conducted a retrospective cohort study of patients treated with magnesium sulfate for preterm labor from December 2006 to June 2010. Data were abstracted from review of individual patient electronic medical records.
