3,6-Dibromo-9-(4-bromo-benz-yl)-9H-carbazole.

Acta Crystallogr Sect E Struct Rep Online

Published: January 2009

The title compound, C(19)H(12)Br(3)N, was synthesized by N-alkyl-ation of 1-bromo-4-(bromo-meth-yl)benzene with 3,6-dibromo-9H-carbazole. There are two unique mol-ecules in the asymmetric unit. The carbazole ring system is essentially planar, with a mean deviation of 0.0402 Å for one mol-ecule and 0.0279 Å for the other. The carbazole planes are inclined to the benzene ring planes at dihedral angles of 58.3 (3) and 71.1 (3)° in the two mol-ecules.

Systematic reviews (SR) synthesize evidence-based medical literature, but they involve labor-intensive manual article screening. Large language models (LLMs) can select relevant literature, but their quality and efficacy are still being determined compared to humans. We evaluated the overlap between title- and abstract-based selected articles of 18 different LLMs and human-selected articles for three SR.

Aims: ERCP training should adapt to the rapid development of ERCP technology and indications. China has a large population and vast land area, but ERCP training resources are insufficient. To make effective use of scarce ERCP training resources, the Standardized Training for ERCP Procedure (STEP) program was launched as a pilot trial.

Purpose Of Review: Knee osteoarthritis (OA) is a gradual deterioration of articular cartilage characterized by pain and physical dysfunction. Although analgesic pharmacological agents are the first-line treatment for knee OA, they are not effective for all patients. In this study, we evaluate the efficacy of an intra-articular injection treatment using platelet-rich plasma (PRP) in reducing pain and improving functional ability.

This study compares laparoscopic (LRP) and robotic-assisted (RARP) radical prostatectomy to identify external and internal disruptive events, focusing on tasks that require heightened attention and coordination among the surgical team. Observations conducted across three hospitals in Australia and China. Data collection was rigorously ensured through the analysis of video recordings and consultations with surgeons, followed by statistical analysis using the Wilcoxon Signed Rank test.
