Michael Hortsch

Anat Sci Educ 2019 Jan 19. Epub 2019 Jan 19.

Department of Cell and Developmental Biology, University of Michigan Medical School, Ann Arbor, Michigan.

When educators develop and introduce new learning approaches or resources, they usually have specific didactic goals in mind that they want to achieve. However, these goals may not always match the needs of their students, who often confound such plans by finding new and different uses for the educational tools that are offered to them. Originating from the author's work as the histology component director at the University of Michigan, the experience described here provides an example of a learning resource being re-appropriated by the learning community.

Assessment of individual bioequivalence using sufficient bootstrap procedure.

Authors:
Ufuk Beyaztas

Pharm Stat 2019 Jan 20. Epub 2019 Jan 20.

Department of Statistics, Bartin University, Bartin, Turkey.

This paper proposes a sufficient bootstrap method, which uses only the unique observations in the resamples, to assess the individual bioequivalence under 2 × 4 randomized crossover design. The finite sample performance of the proposed method is illustrated by extensive Monte Carlo simulations as well as a real-experimental data set, and the results are compared with those obtained by the traditional bootstrap technique. Our records reveal that the proposed method is a good competitor or even better than the classical percentile bootstrap confidence limits. Read More

Barriers to ultrasound guidance for central venous access: a survey among Dutch intensivists and anaesthesiologists.

J Clin Monit Comput 2019 Jan 19. Epub 2019 Jan 19.

Department of Anaesthesiology, Intensive Care and Pain Medicine, Catharina Hospital, Michelangelolaan 2, 5623 EJ, Eindhoven, The Netherlands.

Accumulating evidence shows that ultrasound (US) guidance improves effectiveness and safety of central venous catheter (CVC) placement. Several international guidelines therefore recommend the use of US for placement of CVCs. However, surveys show that the landmark-based technique is still widely used, while the percentage of physicians using US is increasing less than expected. Read More

Chemical carcinogenicity revisited 2: Current knowledge of carcinogenesis shows that categorization as a carcinogen or non-carcinogen is not scientifically credible.

Regul Toxicol Pharmacol 2019 Jan 17. Epub 2019 Jan 17.

Syngenta Crop Protection, LLC, Greensboro, NC, 27419, USA.

Developments in the understanding of the etiology of cancer have undermined the 1970s concept that chemicals are either "carcinogens" or "non-carcinogens". The capacity to induce cancer should not be classified in an inflexible binary manner as present (carcinogen) or absent (non-carcinogen). Chemicals may induce cancer by three categories of mode of action: direct interaction with DNA or DNA replication including DNA repair and epigenetics; receptor-mediated induction of cell division; and non-specific induction of cell division.

Comparison of first moment STEM with conventional differential phase contrast and the dependence on electron dose.

Ultramicroscopy 2018 Dec 30. Epub 2018 Dec 30.

Institute for Solid State Physics, University of Bremen, Otto-Hahn-Allee 1, Bremen, 28359 Germany.

This study addresses the comparison of scanning transmission electron microscopy (STEM) measurements of momentum transfers using the first moment approach and the established method that uses segmented annular detectors. Using an ultrafast pixelated detector to acquire four-dimensional, momentum-resolved STEM signals, both the first moment calculation and the calculation of the differential phase contrast (DPC) signals are done for the same experimental data. In particular, we investigate the ability to correct the segment-based signal to yield a suitable approximation of the first moment for cases beyond the weak phase object approximation. Read More

Modulation of brain function by targeted delivery of GABA through the disrupted blood-brain barrier.

Neuroimage 2019 Jan 16. Epub 2019 Jan 16.

Department of Radiology, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, USA.

The technology of transcranial focused ultrasound (FUS) enables a novel approach to neuromodulation, a tool for selective manipulation of brain function to be used in neurobiology research and with potential applications in clinical treatment. The method uses transcranial focused ultrasound to non-invasively open the blood-brain barrier (BBB) in a localized region such that a systemically injected neurotransmitter chemical can be delivered to the targeted brain site. The approach modulates the chemical signaling that occurs in and between neurons, making it complimentary to most other neuromodulation techniques that affect the electrical properties of neuronal activity.

Femtoliter droplet confinement of Streptococcus pneumoniae: bacterial genetic transformation by cell-cell interaction in droplets.

Lab Chip 2019 Jan 18. Epub 2019 Jan 18.

Department of Bioengineering, University of Illinois at Chicago, Chicago, IL, USA.

Streptococcus pneumoniae (pneumococcus), a deadly bacterial human pathogen, uses genetic transformation to gain antibiotic resistance. Genetic transformation begins when a pneumococcal strain in a transient specialized physiological state called competence, attacks and lyses another strain, releasing DNA, taking up fragments of the liberated DNA, and integrating divergent genes into its genome. While many steps of the process are known and generally understood, the precise mechanism of this natural genetic transformation is not fully understood and the current standard strategies to study it have limitations in specifically controlling and observing the process in detail.

Vancomycin Pharmacokinetics Throughout Life: Results from a Pooled Population Analysis and Evaluation of Current Dosing Recommendations.

Clin Pharmacokinet 2019 Jan 17. Epub 2019 Jan 17.

Department of Anesthesiology, University Medical Center Groningen, University of Groningen, P.O. Box 30001, 9700 RB, Groningen, The Netherlands.

Background And Objectives: Uncertainty exists regarding the optimal dosing regimen for vancomycin in different patient populations, leading to a plethora of subgroup-specific pharmacokinetic models and derived dosing regimens. We aimed to investigate whether a single model for vancomycin could be developed based on a broad dataset covering the extremes of patient characteristics. Furthermore, as a benchmark for current dosing recommendations, we evaluated and optimised the expected vancomycin exposure throughout life and for specific patient subgroups. Read More

Effects of balance evaluation comparison of dynamic balance and Y balance.

J Exerc Rehabil 2018 Dec 27;14(6):939-943. Epub 2018 Dec 27.

Department of Physical Therapy, College of Nursing and Healthcare Science, Dong-eui University, Busan, Korea.

This study measured balance ability using both an existing clinical test tool, the Y-balance test (YBT), and an automated version of the YBT named the dynamic balance test (DBT) developed in this study. Correlations between the two methods were examined to determine whether the DBT can be used as an objective tool for balance ability evaluation. The subjects included in the study were 32 healthy male adults in their 20s, who were randomized into two groups, YBT and DBT, to compare the balance ability between the two groups. Read More

Structure-Activity Relationships of Central Nervous System Penetration by Fatty Acid Amide Hydrolase (FAAH)-Targeted Thyromimetic Prodrugs.

ACS Med Chem Lett 2019 Jan 4;10(1):111-116. Epub 2018 Dec 4.

Department of Physiology & Pharmacology, and Department of Neurology, Oregon Health & Science University, 3181 SW Sam Jackson Park Road, Portland, Oregon 97239, United States.

Thyroid hormone (TH) action is of clinical interest in treating demyelinating diseases of the central nervous system (CNS). Two amide prodrugs of sobetirome, a potent thyroid hormone agonist, were previously shown to significantly improve CNS selective distribution of the parent drug through hydrolysis in the CNS by fatty acid amide hydrolase (FAAH). This concept is elaborated upon here with a series of 29 amide prodrugs targeting FAAH. Read More

On the chordae structure and dynamic behaviour of the mitral valve.

IMA J Appl Math 2018 Nov 30;83(6):1066-1091. Epub 2018 Aug 30.

School of Mathematics and Statistics, University of Glasgow, UK.

We develop a fluid-structure interaction (FSI) model of the mitral valve (MV) that uses an anatomically and physiologically realistic description of the MV leaflets and chordae tendineae. Three different chordae models-complex, 'pseudo-fibre' and simplified chordae-are compared to determine how different chordae representations affect the dynamics of the MV. The leaflets and chordae are modelled as fibre-reinforced hyperelastic materials, and FSI is modelled using an immersed boundary-finite element method. Read More

Universality of the DNA methylation codes in Eucaryotes.

Sci Rep 2019 Jan 17;9(1):173. Epub 2019 Jan 17.

University Perpignan Via Domitia, IHPE UMR 5244, CNRS, IFREMER, University Montpellier, F-66860, Perpignan, France.

Genetics and epigenetics are tightly linked heritable information classes. Question arises if epigenetics provides just a set of environment dependent instructions, or whether it is integral part of an inheritance system. We argued that in the latter case the epigenetic code should share the universality quality of the genetic code. Read More

The p12 subunit of human polymerase δ uses an atypical PIP-box for molecular recognition of proliferating cell nuclear antigen (PCNA).

J Biol Chem 2019 Jan 17. Epub 2019 Jan 17.

Molecular and Cell Biology, University of Leicester, United Kingdom.

Human DNA polymerase δ is essential for DNA replication and acts in conjunction with the processivity factor proliferating cell nuclear antigen (PCNA). Besides its catalytic subunit (p125), pol δ comprises three regulatory subunits (p50, p68, and p12). PCNA interacts with all of these subunits, but only the interaction with p68 has been structurally characterized. Read More

polyRAD: Genotype Calling with Uncertainty from Sequencing Data in Polyploids and Diploids.

G3 (Bethesda) 2019 Jan 17. Epub 2019 Jan 17.

University of Illinois at Urbana-Champaign.

Low or uneven read depth is a common limitation of genotyping-by-sequencing (GBS) and restriction site-associated DNA sequencing (RAD-seq), resulting in high missing data rates, heterozygotes miscalled as homozygotes, and uncertainty of allele copy number in heterozygous polyploids. Bayesian genotype calling can mitigate these issues, but previously has only been implemented in software that requires a reference genome or uses priors that may be inappropriate for the population. Here we present several novel Bayesian algorithms that estimate genotype posterior probabilities, all of which are implemented in a new R package, polyRAD. Read More

1D "Spikelet" Projections from Heteronuclear 2D NMR Data-Permitting 1D Chemometrics While Preserving 2D Dispersion.

Metabolites 2019 Jan 16;9(1). Epub 2019 Jan 16.

Environmental NMR Center, Department of Physical and Environmental Sciences, University of Toronto Scarborough, Military Trial, Toronto, ON 1265, Canada.

Nuclear magnetic resonance (NMR) spectroscopy is a powerful tool for the non-targeted metabolomics of intact biofluids and even living organisms. However, spectral overlap can limit the information that can be obtained from 1D 1H NMR. For example, magnetic susceptibility broadening in living organisms prevents any metabolic information being extracted from solution-state 1D 1H NMR. Read More

Sex differences in the intensity of cross-sensitization between methylphenidate and amphetamine in adolescent rats.

Physiol Behav 2019 Jan 14. Epub 2019 Jan 14.

McGovern Medical School, University of Texas Health Science Center, Houston, TX 77006, United States. Electronic address:

Chronic use of psychostimulants such as methylphenidate (MPD) and amphetamine (Amph) leads to abuse and dependence. Cross-sensitization occurs when exposure to a drug causes a significant intensified response to a different drug as compared to the effect of the drug in subjects with no previous exposure. Cross-sensitization is used as an experimental correlate for a drug's potential to elicit dependence. Read More

An analysis of RUC methodology for determining the RVU valuation of sinus surgery.

Int Forum Allergy Rhinol 2019 Jan 17. Epub 2019 Jan 17.

Division of Otolaryngology-Head and Neck Surgery, University of Utah, Salt Lake City, UT.

Background: The Relative Value Scale Update Committee, commonly known as the RUC, is responsible for defining the value of Current Procedural Terminology (CPT) codes. The RUC process uses survey responses reporting operative times to determine procedure reimbursement, but it is limited by low response rates, small sample sizes, and unclear generalizability of the results. By comparing actual reported intraoperative times to the times determined by the RUC process, in this study we sought to assess the performance of RUC methodology in endoscopic sinus surgery (ESS).

New QSPR Models to Predict the Flammability of Binary Liquid Mixtures.

Mol Inform 2019 Jan 17. Epub 2019 Jan 17.

INERIS, Accidental Risk Division Parc Technologique Alata, 60550, Verneuil-en-Halatte, France.

New Quantitative Structure-Property Relationships (QSPR) are presented to predict the flash point of binary liquid mixtures, based on more than 600 experimental flash points for 60 binary mixtures. Two models are proposed based on a GA-MLR approach that uses a genetic algorithm (GA) variable selection in multilinear regressions (MLR). In these models, mixtures were characterized by a series of mixture descriptors calculated from various mixture formula combining the molecular descriptors of the single compounds constituting the mixtures and their respective molar fractions in the mixture.
