From 1994 through 2019, 76 publications on epilepsy-related epidemiologic and surveillance studies were identified. Over the past 25 years, CDC has expanded community, state, and national surveillance on epilepsy and supported epidemiologic studies by using multiple assessment methods and validated case-ascertainment criteria to identify epilepsy burden, epilepsy-related outcomes, and healthcare utilization in the general population or in population subgroups. Among identified research opportunities, studies on epilepsy incidence and risk factors, mortality, and cost are considered as important surveillance gaps. Other remaining gaps and suggested surveillance strategies are also proposed. Findings from this review may help epilepsy researchers and other stakeholders reference and prioritize future activities for epidemiologic and surveillance studies in epilepsy.Rationale and objectives We report the creation of a voluntary research development curriculum for radiology residents at our institution, detailing outcomes after 6 years of existence. Materials and methods We developed a comprehensive Academic and Research Track (ART) curriculum for radiology residents in our department, including mentorship, monthly meetings, didactic curriculum, ongoing evaluation/feedback, protected academic time, and financial support. A literature review identified all indexed publications for our residency graduates from 6 years pre- (2007-2012) to 6 years post-ART (2013-2018) intervention. We also documented career outcomes (academic versus private practice). Summary statistics, Chi-square, and Poisson regression analyses were performed. Results ART group demonstrated significantly greater publication likelihood versus pre-ART predecessors (odds ratio [OR] 3.59, 95% confidence intervals [CI] 1.40-9.19; risk ratios [RR] 1.58, 95% CI 1.19-2.11; p= 0.01), contemporaneous non-ART cohort (OR 3.03, 95% CI 1.12-8.33; RR 1.45, 95% CI 1.08-1.96; p = 0.04), and combined pre-ART plus non-ART group (OR 3.34, 95% CI 1.35-8.22; RR 1.41, 95% CI 0.87-2.29; p = 0.012). In Poisson regression, ART was a significant factor for total, first author, and senior author publications among all graduates and among the subset which remained in academics (all p-values less then 0.05). Estimators were positive in all regressions, indicating a positive effect of ART for increasing numbers of publications. Conclusion ART membership was associated with significantly increased indexed publications. A greater proportion of ART members remained in academics compared to non-ART members, but did not reach statistical significance. We detail our ART structure and curriculum, which may be used as a malleable template for other radiology departments.Ribozymes with modular structures are attractive platforms for the construction of nanoscale RNA objects with biological functions. We designed group I ribozyme dimers as unit ribozyme dimers (Urds), which self-assembled to form their polymeric states and also oligomeric states with defined numbers of Urds. Assembly of Urds yielded catalytic ability of a pair of distinct ribozyme units to cleave two distinct substrates. The morphologies of the assembled ribozyme structures were observed directly by atomic force microscopy (AFM).A gene encoding a dye-linked d-amino acid dehydrogenase (Dye-DADH) homologue was found in a hyperthermophilic archaeon, Sulfurisphaera tokodaii. The predicted amino acid sequence suggested that the gene product is a membrane-bound type enzyme. The gene was overexpressed in Escherichia coli, but the recombinant protein was exclusively produced as an inclusion body. In order to avoid production of the inclusion body, an expression system using the thermoacidophilic archaeon Sulfolobus acidocaldarius instead of E. coli as the host cell was constructed. The gene was successfully expressed in S. acidocaldarius, and its product was purified to homogeneity and characterized. The purified enzyme catalyzed the dehydrogenation of various d-amino acids, with d-phenylalanine being the most preferred substrate. The enzyme retained its full activity after incubation at 90 °C for 30 min and after incubation at pH 4.0-11.0 for 30 min at 50 °C. This is the first report on membrane-bound Dye-DADH from thermophilic archaea that was successfully expressed in an archaeal host.Introduction Relative value units (RVU) are the measure of value used in United States Medicare and Medicaid reimbursement. The Relative Update Committee (RUC) determine physician work RVU (wRVU) based on operative time, technical skill and effort, mental effort and judgement, and stress. In theory, wRVU should account for the complexity and operative time involved in a procedure. Objective The primary aim of this study is to assess if operative time and complexity of hypospadias surgery is adequately accounted for by the current wRVU assignments. Study design The American College of Surgeons National Surgical Quality Improvement Program Participant User File (ACS-NSQIP PUF) database was utilized from 2012 to 2017. Single stage hypospadias current procedural terminology (CPT) codes (including acceptable secondary CPT codes) were extracted. Using total wRVU and total operative time, the primary variable of wRVU per hour was calculated (wRVU/hr). Multivariable linear regression analysis was used to assess the rssion This the first objective assessment of the current wRVU assignments with regards to one stage hypospadias repairs. Tolebrutinib research buy More complex and longer hypospadias procedures are not adequately compensated by wRVU. Most notably, simple distal procedures are reimbursed at a mean of 19.5 wRVU/hr compared to 13.2 wRVU/hr for one stage proximal repairs. Conclusion This analysis of national-level data suggests that the current wRVU assignments significantly favor shorter and simpler procedures in hypospadias surgery.Dynamic ultrasound scattering allows us to investigate the particle motion and its average size via the time-evolution analysis of the scattering amplitude in optically turbid media. Recently, we proposed a novel particle sizing method that simultaneously analyzes the depth dependences on the sedimentation velocity and the scattered intensity without prior knowledge about the shape of the size distribution (Ultrasonics, 65 (2016) 59-68). In this study, the applicability of the technique to Fluorinert/water dilute and concentrated emulsions (up to 40 vol%) was examined. For the bimodal distribution of the emulsion, the size distribution of the particles was successfully obtained by directly probing the particle motion with different sizes as a function of the sample depth. The validity of the analysis was also investigated by comparing with conventional ultrasonic spectroscopy.
