An 81 year-old female presented to the emergency department with complaints of blood in her urine and stool for 1 day and new onset of weakness. She has a history of congestive heart failure, type 2 diabetes, and nonalcoholic steatohepatitis. She had a cough one week ago. At presentation she appeared jaundiced. The patient had no recent blood transfusions. Relevant laboratory values (Table 1) and blood bank test results (Table 2) are reported below.

Her initial physical exam in the emergency department revealed a distended, non-tender lower abdomen with a large palpable midline mass. The remainder of her physical exam was unremarkable. Initial laboratory workup was unremarkable, including normal levels AFP, hCG, LDH, CEA-125, and estriol. She underwent ultrasound of the abdomen and CT scan of the chest, abdomen, and pelvis (Figure 1). The CT scan revealed a solid, enhancing, 19 x 12 x 10 cm multilobulated mass arising from the left aspect of the uterus. This mass distorted the endometrial cavity and exerted significant mass effect on the iliac veins, iliac arteries, and distal ureters. The remainder of the abdominal and thoracic CT was unremarkable. The initial interpretation was worrisome for uterine malignancy, such as leiomyosarcoma or other uterine sarcomas. There was also some concern, based on the combined interpretation of the CT and ultrasound, that the mass could be arising from one or both ovaries. After discussion with the patient and her family of the above findings, and because the patient was clinically stable, she was discharged to home with short interval follow-up. A subsequent MRI of the abdomen and pelvis two days later as an outpatient showed normal appearing ovaries and re-demonstrated the large uterine mass (Figure 2).

Physical examination showed normal vital signs. There was no difficulty breathing, chest pain, or headache. Neurologic evaluation demonstrated an awake and alert, right-handed female oriented to person, place, and time. She was noted to have persistent word finding difficulty and was unable to name a pen and a watch. At the time of neurological testing, the patient's motor and sensory function had essentially returned to normal. Cranial nerves were intact bilaterally and deep tendon reflexes were symmetric and slightly reduced. Her gait was unremarkable and Romberg testing was negative.

The patient started early intervention shortly after the onset of symptoms, but therapies were limited due to his oppositional behaviors. After evaluation by a developmental pediatrician, he did not meet diagnostic criteria for autism spectrum disorder. The physical exam was unremarkable, an audiology test was normal, and a brain MRI showed no evidence of focal parenchymal abnormality. Given the patient's medical history, global developmental delays, behavioral issues, as well as a family history of a maternal uncle with brain malformation and similar behavioral issues further genetic testing was undertaken. SNP micro-array analysis was negative for copy number alterations. FMR1 gene mutation analysis by PCR for Fragile X Mental Retardation is shown in Figure 1.

This lesson is an introduction to programming in Python for people with little or no previous programming experience. It uses plotting as its motivating example, and is designed to be used in both Data Carpentry and Software Carpentry workshops. This lesson references JupyterLab, but can be taught using a regular Python interpreter as well. Please note that this lesson uses Python 3 rather than Python 2.

This resource provides lecture notes and writing assignments for the study of poetry. While specific poems are presented here, these notes and assignments can be adapted and applied to practically any thematic group of poems.  The unit contains several modules. The first posits the work of African American poet Langston Hughes as poems that establish a legacy of oratorical poems addressing social issues faced not only by African Americans, but by any and all Americans, especially the historically disenfranchised.  The unit explores poems in Hughes' legacy, focusing on three poems by African American poets Maya Angelou, Elizabeth Alexander, and Amanda Gorman, who composed U.S. presidential inaugural poems. The second module explores nature poetry. Students read and analyze poems that explore, ponder and sometimes celebrate the relationship between human beings and nature. Ultimately, students compose poetry explication essays. The third module explores the book-length prose poem "I Remember" (Joe Brainard), teaching students to locate and make use of peer-reviewed articles.  Additionally, students write their own "I Remember" poems. Included are introductory lecture, discussion , short writing, explication , and several other assignments. Unless otherwise noted, the materials in this unit are licensed under CC BY-NC-SA.

This course provides a thorough introduction to the C programming language, the workhorse of the UNIX operating system and lingua franca of embedded processors and micro-controllers. The first two weeks will cover basic syntax and grammar, and expose students to practical programming techniques. The remaining lectures will focus on more advanced concepts, such as dynamic memory allocation, concurrency and synchronization, UNIX signals and process control, library development and usage. Daily programming assignments and weekly laboratory exercises are required. Knowledge of C is highly marketable for summer internships, UROPs, and full-time positions in software and embedded systems development.

The course introduces formal theories of context-dependency, presupposition, implicature, context-change, focus and topic. Special emphasis is on the division of labor between semantics and pragmatics. It also covers applications to the analysis of quantification, definiteness, presupposition projection, conditionals and modality, anaphora, questions and answers.

The evidence-based community has championed the public registration of pre-analysis plans (PAPs) as a solution to the problem of research credibility, but without any evidence that PAPs actually bolster the credibility of research. We analyze a representative sample of 195 pre-analysis plans (PAPs) from the American Economic Association (AEA) and Evidence in Governance and Politics (EGAP) registration platforms to assess whether PAPs are sufficiently clear, precise and comprehensive to be able to achieve their objectives of preventing “fishing” and reducing the scope for post-hoc adjustment of research hypotheses. We also analyze a subset of 93 PAPs from projects that have resulted in publicly available papers to ascertain how faithfully they adhere to their pre-registered specifications and hypotheses. We find significant variation in the extent to which PAPs are accomplishing the goals they were designed to achieve

Data Carpentry Genomics workshop lesson to learn how to structure your metadata, organize and document your genomics data and bioinformatics workflow, and access data on the NCBI sequence read archive (SRA) database. Good data organization is the foundation of any research project. It not only sets you up well for an analysis, but it also makes it easier to come back to the project later and share with collaborators, including your most important collaborator - future you. Organizing a project that includes sequencing involves many components. There’s the experimental setup and conditions metadata, measurements of experimental parameters, sequencing preparation and sample information, the sequences themselves and the files and workflow of any bioinformatics analysis. So much of the information of a sequencing project is digital, and we need to keep track of our digital records in the same way we have a lab notebook and sample freezer. In this lesson, we’ll go through the project organization and documentation that will make an efficient bioinformatics workflow possible. Not only will this make you a more effective bioinformatics researcher, it also prepares your data and project for publication, as grant agencies and publishers increasingly require this information. In this lesson, we’ll be using data from a study of experimental evolution using E. coli. More information about this dataset is available here. In this study there are several types of files: Spreadsheet data from the experiment that tracks the strains and their phenotype over time Spreadsheet data with information on the samples that were sequenced - the names of the samples, how they were prepared and the sequencing conditions The sequence data Throughout the analysis, we’ll also generate files from the steps in the bioinformatics pipeline and documentation on the tools and parameters that we used. In this lesson you will learn: How to structure your metadata, tabular data and information about the experiment. The metadata is the information about the experiment and the samples you’re sequencing. How to prepare for, understand, organize and store the sequencing data that comes back from the sequencing center How to access and download publicly available data that may need to be used in your bioinformatics analysis The concepts of organizing the files and documenting the workflow of your bioinformatics analysis

This lesson focuses on the conservation of energy solely between gravitational potential energy and kinetic energy, moving students into the Research and Revise step. Students start out with a virtual laboratory, and then move into the notes and working of problems as a group. A few questions are given as homework. A dry lab focuses on the kinetic and potential energies found on a roller coaster concludes the lesson in the Test Your Mettle phase of the Legacy Cycle.

The topic of this video is energy in general, and specifically the ways we can quantify it. In order to make the concepts accessible to a broad audience, this video focuses on everyday things and events. How is it that energy plays a part in a child riding a scooter? How is the energy we consume in playing related to the energy on the food we eat? This video poses these questions to the class and challenges them to put a list of five such items into an ordering from most energy to least.
