Defining the Middle Corona.

The middle corona, the region roughly spanning heliocentric distances from 1.5 to 6 solar radii, encompasses almost all of the influential physical transitions and processes that govern the behavior of coronal outflow into the heliosphere. The solar wind, eruptions, and flows pass through the region, and they are shaped by it.

The IWill MCW Campaign: Individual Actions to Advance Gender Equity.

Advancing equity for women remains an urgent and complex problem at academic health centers. Attempts to mitigate gender gaps have ranged widely and have been both slow to occur and limited in effect. Recognizing the limitations of previously attempted solutions and fueled by the #MeToo and #TimesUp movements, the Medical College of Wisconsin (MCW) stepped outside known approaches (e.

The Great Mask Debate: A Debate That Shouldn't Be a Debate at All.

Background: Despite a rapidly growing and evolving literature, there continues to be a vigorous public debate about whether the community use of face coverings can mitigate the spread of COVID-19 ten months into the pandemic.

Objectives: This article describes a semi-structured literature review of the use of face coverings to prevent the spread of coronaviruses and similar respiratory pathogens, with a focus on SARS-CoV-2 (COVID-19).

Methods: : The author conducted a semi-structured literature review using search terms "COVID19" or "SARS-CoV-2" crossed with "mask/s" or "face covering/s.

Racial/Ethnic Differences In COVID-19 Screening, Hospitalization, And Mortality In Southeast Wisconsin.

This study aimed to understand racial/ethnic differences in coronavirus disease 2019 (COVID-19) screening, symptom presentation, hospitalization, and mortality, using data from 31,549 adults tested for COVID-19 between March 1 and July 10, 2020, in Milwaukee and Southeast Wisconsin. Racial/ethnic differences existed in adults who screened positive for COVID-19 (4.5 percent of non-Hispanic Whites, 14.

Element Abundances: A New Diagnostic for the Solar Wind.

We examine the different element abundances exhibited by the closed loop solar corona and the slow speed solar wind. Both are subject to the first ionization potential (FIP) effect, the enhancement in coronal abundance of elements with FIP below 10 eV (e.g.

DeepSort: deep convolutional networks for sorting haploid maize seeds.

Background: Maize is a leading crop in the modern agricultural industry that accounts for more than 40% grain production worldwide. THe double haploid technique that uses fewer breeding generations for generating a maize line has accelerated the pace of development of superior commercial seed varieties and has been transforming the agricultural industry. In this technique the chromosomes of the haploid seeds are doubled and taken forward in the process while the diploids marked for elimination.

Drug Regimen Individualization for Attention-Deficit/Hyperactivity Disorder: Guidance for Methylphenidate and Dexmethylphenidate Formulations.

In 2000, the first biphasic modified-release (MR) formulation of methylphenidate (MPH) was approved for the treatment of attention-deficit/hyperactivity disorder (ADHD). An immediate-release (IR) MPH pulse (22% of the dose) facilitates rapid onset of stimulant action, while the remaining MR portion of the dose provides for day-long duration of efficacy. A wide array of oral MR-MPH products has subsequently been approved that also allows for once-daily dosing, though each product is characterized by distinctive exposure time courses.

Expanding the Health-care Pipeline through Innovation: The MCW model.

In 2016, the Association of American Medical Colleges projected a physician shortage in the United States of approximately 90,000; in the same year, the Wisconsin Hospital Association projected a shortage of 2,000 physicians in Wisconsin. The Medical College of Wisconsin has begun to address these shortages in three ways: 1) creation of immersive regional medical school campuses in Green Bay and Central Wisconsin, in partnership with rural serving health systems; 2) creation of rural-based psychiatry and family medicine residency programs in Green Bay and central Wisconsin; and 3) expansion of the scope of practice of pharmacists through creation of a new School of Pharmacy in collaboration with the Medical College of Wisconsin School of Medicine. This article will discuss those approaches, history and progress to date, principles used, and future plans to address the impending physician shortages.

Science of health care delivery as a first step to advance undergraduate medical education: A multi-institutional collaboration.

Physicians must possess knowledge and skills to address the gaps facing the US health care system. Educators advocate for reform in undergraduate medical education (UME) to align competencies with the Triple Aim. In 2014, five medical schools and one state university began collaborating on these curricular gaps.

A Motion Tracking and Sensor Fusion Module for Medical Simulation.

Here we introduce a motion tracking or navigation module for medical simulation systems. Our main contribution is a sensor fusion method for proximity or distance sensors integrated with inertial measurement unit (IMU). Since IMU rotation tracking has been widely studied, we focus on the position or trajectory tracking of the instrument moving freely within a given boundary.

Three-Year Experience of an Academic Medical Center Ombuds Office.

An ombuds is an individual who informally helps people or groups (visitors) resolve disputes and/or interpersonal conflicts as an alternative to formal dispute resolution mechanisms within an organization. Ombuds are nearly ubiquitous in many governmental, business, and educational settings but only recently have gained visibility at medical schools. Medical schools in the United States are increasingly establishing ombuds offices as part of comprehensive conflict management systems to address concerns of faculty, staff, students, and others.

The Advancing a Healthier Wisconsin Endowment: How a Health Care Conversion Foundation Is Transforming a Medical School.

Health care conversion foundations, such as the Advancing a Healthier Wisconsin Endowment (the endowment) at the Medical College of Wisconsin (MCW), result from the conversion of nonprofit health organizations to for-profit corporations. Over the past several decades, nearly 200 of these foundations have been created, and they have had a substantial impact on the field of health philanthropy. The MCW was a recipient of funds resulting from Blue Cross & Blue Shield United of Wisconsin's conversion from a nonprofit to a for-profit status in 1999.

The Merits and Challenges of Three-Year Medical School Curricula: Time for an Evidence-Based Discussion.

The debate about three-year medical school curricula has resurfaced recently, driven by rising education debt burden and a predicted physician shortage. In this Perspective, the authors call for an evidence-based discussion of the merits and challenges of three-year curricula. They examine published evidence that suggests that three-year curricula are viable, including studies on three-year curricula in (1) U.

The role of turbulence in coronal heating and solar wind expansion.

Plasma in the Sun's hot corona expands into the heliosphere as a supersonic and highly magnetized solar wind. This paper provides an overview of our current understanding of how the corona is heated and how the solar wind is accelerated. Recent models of magnetohydrodynamic turbulence have progressed to the point of successfully predicting many observed properties of this complex, multi-scale system.

Isoproterenol acts as a biased agonist of the alpha-1A-adrenoceptor that selectively activates the MAPK/ERK pathway.

The α1A-AR is thought to couple predominantly to the Gαq/PLC pathway and lead to phosphoinositide hydrolysis and calcium mobilization, although certain agonists acting at this receptor have been reported to trigger activation of arachidonic acid formation and MAPK pathways. For several G protein-coupled receptors (GPCRs) agonists can manifest a bias for activation of particular effector signaling output, i.e.

Epidermal growth factor-induced proliferation of collecting duct cells from Oak Ridge polycystic kidney mice involves activation of Na+/H+ exchanger.

Epidermal growth factor (EGF) is linked to the pathogenesis of polycystic kidney disease (PKD). We explored signaling pathways activated by EGF in orpk cilia (-) collecting duct cell line derived from a mouse model of PKD (hypomorph of the Tg737/Ift88 gene) with severely stunted cilia, and in a control orpk cilia (+) cell line with normal cilia. RT-PCR demonstrated mRNAs for EGF receptor subunits ErbB1, ErbB2, ErbB3, ErbB4, and mRNAs for Na(+)/H(+) exchangers (NHE), NHE-1, NHE-2, NHE-3, NHE-4, and NHE-5 in both cell lines.

Suppression of GNAI2 message in ovarian cancer.

Background: Understanding the integration of hormone signaling and how it impacts oncogenesis is critical for improved cancer treatments. Here we elucidate GNAI2 message alterations in ovarian cancer (OvCa). GNAI2 is a heterotrimeric G protein which couples cell surface hormone receptors to intracellular enzymes, and is best characterized for its direct role in regulating cAMP response element-binding protein (CREB) function by decreasing intracellular cAMP through inhibiting adenylyl cyclase.

Phosphorus in the young supernova remnant Cassiopeia A.

Phosphorus ((31)P), which is essential for life, is thought to be synthesized in massive stars and dispersed into interstellar space when these stars explode as supernovae (SNe). Here, we report on near-infrared spectroscopic observations of the young SN remnant Cassiopeia A, which show that the abundance ratio of phosphorus to the major nucleosynthetic product iron ((56)Fe) in SN material is up to 100 times the average ratio of the Milky Way, confirming that phosphorus is produced in SNe. The observed range is compatible with predictions from SN nucleosynthetic models but not with the scenario in which the chemical elements in the inner SN layers are completely mixed by hydrodynamic instabilities during the explosion.

Sustained activation of protein kinase C induces delayed phosphorylation and regulates the fate of epidermal growth factor receptor.

It is well established that acute activation of members of the protein kinase C (PKC) family induced by activation of cellular receptors can transduce extracellular stimuli to intracellular signaling. However, the functions of sustained activation of PKC are not well studied. We have previously shown that sustained activation of classical PKC isoforms over 15-60 min induced the formation of the pericentrion, a subset of recycling endosomes that are sequestered perinuclearly in a PKC- and phospholipase D (PLD)-dependent manner.

An integral view of fast shocks around supernova 1006.

Supernova remnants are among the most spectacular examples of astrophysical pistons in our cosmic neighborhood. The gas expelled by the supernova explosion is launched with velocities ~1000 kilometers per second into the ambient, tenuous interstellar medium, producing shocks that excite hydrogen lines. We have used an optical integral-field spectrograph to obtain high-resolution spatial-spectral maps that allow us to study in detail the shocks in the northwestern rim of supernova 1006.

The bradykinin B(2) receptor induces multiple cellular responses leading to the proliferation of human renal carcinoma cell lines.

Background: The vasoactive peptide bradykinin (BK) acts as a potent growth factor for normal kidney cells, but there have been few studies on the role of BK in renal cell carcinomas.

Purpose: In this study, we tested the hypothesis that BK also acts as a mitogen in kidney carcinomas, and explored the effects of BK in human renal carcinoma A498 cells.

Methods: The presence of mRNAs for BK B(1) and BK B(2) receptors in A498 cells was demonstrated by reverse transcription-polymerase chain reaction.

Relating molecular properties and in vitro assay results to in vivo drug disposition and toxicity outcomes.

A primary goal of lead optimization is to identify compounds with improved absorption, distribution, metabolism, excretion, and toxicity (ADMET) properties. A number of reports have linked computed molecular properties to desirable in vivo ADMET outcomes, but a significant limitation of these analyses is the failure to control statistically for possible covariates. We examine the relationship between molecular properties and in vitro surrogate assays vs in vivo properties within 173 chemical series from a database of 3773 compounds with rodent pharmacokinetic and toxicology data.
