We report the first example of BAC-Cu complex (BAC = bis(diisopropylamino)cyclopropenylidene) and its use as a carbene-transfer reagent, allowing access to Au-, Pd-, Ir- and Rh-BAC compounds. Catalytic experiments show the high activity of the [CuCl(BAC)] complex in Click chemistry.

Determining which statistical methods are appropriate for data is both user and data dependent and prone to change as new methodology becomes available. This process encompasses model ideation, model selection, and determining appropriate use of statistical methods. Literature on models for animal movement emerging in the past two decades has yielded a rich collection of statistical methods garnering much deserved positive attention.

Objectives In Japan, clinical diagnosis based solely on symptoms, without the use of test kits, has been adopted to enable the rapid identification of individuals infected with coronavirus disease 2019 (COVID-19). A history of close contact with COVID-19 patients is a prerequisite for such symptom-based diagnosis. However, the current diagnostic criteria lack objectivity.

Objective: This study aimed to evaluate the influence of computed tomography (CT) on the preoperative planning of posterior malleolus (PM) fractures of the ankle, comparing its information with that of conventional radiographs and assessing its impact on surgical treatment.
Methods: The study included 81 patients with PM fractures, whose radiological and CT images were analyzed by 33 specialized orthopedic surgeons. The study had two stages, with a radiological assessment on the first, and the second having radiological plus CT evaluation.

Exposure systems to study the effects of environmental exposures can be costly to purchase and difficult to use. Here, we present an accessible and cost-effective approach to building an exposure chamber in the lab. We describe steps for constructing the exposure system and writing the code to run it and simple instructions for experiments using the system.
