Intra-Individual Variability Adaptively Increases Following Inhibition Training During Middle Childhood, Roser Cañigueral, Keertana Ganesan, Claire R Smid, Abigail Thompson, Nico U F Dosenbach, Nikolaus Steinbeis

2020-Current year OA Pubs

There is ongoing debate on the relationship between intra-individual variability (IIV) of cognitive processes and task performance. While psychological research has traditionally assumed that lower intra-individual variability (IIV) aids consistent task performance, some studies suggest that greater IIV can also be adaptive, especially when flexible responding is required. Here we selectively manipulate inhibitory control (Stopping) and response speed (Going) by means of a training paradigm to 1) assess how this manipulation impacts Stopping IIV and its relationship to task performance, and 2) replicate previous findings showing that reductions in Going IIV are adaptive. A group of 208 6-13-year-old children were …

2020-Current year OA Pubs

Numerous studies have demonstrated the clinical benefits of continuous glucose monitoring (CGM) in individuals with type 1 diabetes (T1D) and type 2 diabetes (T2D) who are treated with intensive insulin regimens. Based on this evidence, CGM is now a standard of care for individuals within these diabetes populations and widely covered by commercial and public insurers. Moreover, recent clinical guidelines from the American Diabetes Association and American Association of Clinical Endocrinology now endorse CGM use in individuals treated with nonintensive insulin regimens. However, despite increasing evidence supporting CGM use for individuals treated with less-intensive insulin therapy or noninsulin medications, insurance …

Short Tandem Repeat Profiling Via Next-Generation Sequencing For Cell Line Authentication, Yi-Hsien Chen, Jon P Connelly, Colin Florian, Xiaoxia Cui, Shondra M Pruett-Miller

2020-Current year OA Pubs

Cell lines are indispensable models for modern biomedical research. A large part of their usefulness derives from the ability of a cell line to proliferate over multiple passages (often indefinitely), allowing multiple experiments to be performed. However, over time, cell line identity and purity can be compromised by human errors. Cross-contamination from other cell lines and complete misidentification are both possible. Routine cell line authentication is a necessary preventive measure and has become a requirement for many funding applications and publications. Short tandem repeat (STR) profiling is the most common method for cell line authentication and is usually carried out …

Frequently changing cervical cancer screening guidelines over the past two decades have been inconsistently adopted in the United States. Current guidelines set the recommended screening interval to three years for average-risk women aged 21-29 years. Few studies have evaluated how patient and provider factors are associated with implementation of cervical cancer screening intervals among younger women. This study evaluated multilevel factors associated with screening interval length among 69,939 women aged 21-29 years with an initial negative Pap screen between 2010 and 2015 across three large health systems in the U.S. Shorter-interval screening was defined as a second screening Pap within …

Peripheral Nodular Enhancement In Adrenal And Renal Hematomas: A Report Of 3 Cases, Gentry Russell, Pooja Navale, Daniel R Ludwig, Benjamin S Strnad, Malak Itani

2020-Current year OA Pubs

There are a wide range of benign and malignant pathologies that the radiologist may encounter in the adrenal glands and kidneys, often incidentally when imaging is performed for other indications. Many imaging modalities including CT, MR, and US are often used in an attempt to characterize these lesions. A definitive radiological diagnosis, however, is not always possible. This is at times due to atypical presentations of typical lesions which may be mistaken for more aggressive or concerning pathologic conditions. Adrenal lesions that do not demonstrate characteristic benign imaging features might require surgical excision. Similarly, cystic renal lesions that demonstrate nodular …
