Willow Pollen Collection By A Blueberry Specialist Bee (Hymenoptera: Andrenidae), James B. Watson, Keziah G. Bartel, Jason Gibbs

The Great Lakes Entomologist

Andrena (Conandrena) bradleyi Viereck (Hymenoptera: Andrenidae) is widely regarded as a Ericaceae specialist bee due to its elongate head, plant records, and common collection in commercial blueberry fields. We provide evidence of A. bradleyi collecting pollen from willow (Salix, Salicaceae) L. in southeastern Manitoba. This indicates the bee is not obligately specialized on Ericaceae pollens and that early blooming plants may contribute to its early nutritional requirements.

New Record Of The Pavement Ant, Tetramorium Immigrans (Hymenoptera: Formicidae), In South Dakota With Notes On Its Thermal Tolerance And Geographic Distribution, Karl A. Roeder, Skylar Drey, Jesse D. Daniels, Diane V. Roeder, Jackson A. Helms Iv

The Great Lakes Entomologist

The pavement ant, Tetramorium immigrans, is an abundant and widespread species across large portions of the United States. Yet despite its current distribution in Northeastern, Midwestern, Pacific, and Western states, there is a surprising lack of records from the Great Plains. Here we present an updated county list of T. immigrans from museum collections and research grade observations (459 counties; ~15% of US counties), highlighting the first records from one Great Plains state—South Dakota. Observations on community science platforms since 2006 have undoubtedly increased the awareness of T. immigrans (+329 counties; ~72% of all county records), however we posit …

Transformational Leadership And Work Engagement: The Moderating Role Of Intrinsic Motivation, Barbara Grah, Vlado Dimovski, Marko Perić, Simon Colnar, Sandra Penger

Economic and Business Review

We examine the moderating role of intrinsic motivation in the relationship between transformational leadership and work engagement. In a sample of 168 tourism and hospitality employees in the quantitative section, Study 1, we found that the highest level of work engagement is identified when the level of intrinsic motivation is highest. Intrinsically motivated employees then exhibit engaged behaviors at work. In Study 2, we opted for a descriptive design to better understand the findings of Study 1, using interviews with three experts and a three-phase coding analysis. We found that increasing intrinsic motivation further promotes engaged work behavior. This article …

Annual Ryegrass Toxicity In Livestock, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Annual ryegrass toxicity (ARGT) is a potentially fatal poisoning of livestock after consumption of annual ryegrass infected by the bacterium Rathayibacter toxicus (formerly known as Clavibacter toxicus).

The cycle starts with a migratory nematode called Anguina funesta. These nematodes can travel into the flowering parts of developing ryegrass and colonise them, eventually taking over the seed head to form nematode galls.

ARGT problems can start where the bacterium is also present in the same soil. The bacterium is carried by the nematode as it moves into the developing ryegrass flowering parts. Once inside the plant, the bacterium also develops, often …

Temporospatial Deep Learning Strategies For Prediction Of Disease Progression In Radiology, John D. Mayfield

USF Tampa Graduate Theses and Dissertations

While the fields of machine learning and medicine are deeply rooted in axiomatic scientific principles, there is an element of art that makes the practice imperfect, yet innately human. As the two fields have seen the greatest overlap in their collective history, there remains a chasm between them in terms of practical translation for the patients who desire and deserve personalized medicine. As presented in this dissertation, I and my collaborators have contributed to the groundwork for future exploration of predicting disease progression by identifying signals within sequential medical imaging to provide a temporospatial relationship upon which we can make …

Muc20 Regulated By Extrachromosomal Circular Dna Attenuates Proteasome Inhibitor Resistance Of Multiple Myeloma By Modulating Cuproptosis, Xiaobin Wang, Yingqing Shi, Hua Shi, Xiaoyu Liu, Aijun Liao, Zhuogang Liu, Robert Z Orlowski, Rui Zhang, Huihan Wang

Faculty, Staff and Student Publications

BACKGROUND: Proteasome inhibitors (PIs) are one of the most important classes of drugs for the treatment of multiple myeloma (MM). However, almost all patients with MM develop PI resistance, resulting in therapeutic failure. Therefore, the mechanisms underlying PI resistance in MM require further investigation.

METHODS: We used several MM cell lines to establish PI-resistant MM cell lines. We performed RNA microarray and EccDNA-seq in MM cell lines and collected human primary MM samples to explore gene profiles. We evaluated the effect of MUC20 on cuproptosis of PI-resistant MM cells using Co-immunoprecipitation (Co-IP), Seahorse bioenergetic profiling and in vivo assay.

RESULTS: …

A Novel Micropeptide, Slitharin, Exerts Cardioprotective Effects In Myocardial Infarction, Ahmed G. E. Ibrahim, Alessandra Ciullo, Shukuro Yamaguchi, Chang Li, Travis Antes, Xaviar Jones, Liang Li, Ramachandran Murali, Innokentiy Maslennikov, Niveda Sundararaman, Daniel Soetkamp, Eugenio Cingolani, Jennifer Van Eyk, Eduardo Marbán

Pharmacy Faculty Articles and Research

Purpose: Micropeptides are an emerging class of proteins that play critical roles in cell signaling. Here, we describe the discovery of a novel micropeptide, dubbed slitharin (Slt), in conditioned media from Cardiosphere-derived cells (CDCs), a therapeutic cardiac stromal cell type.

Experimental design: We performed mass spectrometry of peptide-enriched fractions from the conditioned media of CDCs and a therapeutically inert cell type (human dermal fibrobasts). We then evaluated the therapeutic capacity of the candidate peptide using an in vitro model of cardiomyocyte injury and a rat model of myocardial infarction.

Results: We identified a novel 24-amino acid micropeptide …

Differentially Disrupted Spinal Cord And Muscle Energy Metabolism In Spinal And Bulbar Muscular Atrophy, Danielle Debartolo, Frederick Arnold, Y Liu, Elana Molotsky, Hsin-Yao Tang, Diane Merry

Department of Biochemistry and Molecular Biology Faculty Papers

Prior studies showed that polyglutamine-expanded androgen receptor (AR) is aberrantly acetylated and that deacetylation of the mutant AR by overexpression of nicotinamide adenine dinucleotide-dependent (NAD+-dependent) sirtuin 1 is protective in cell models of spinal and bulbar muscular atrophy (SBMA). Based on these observations and reduced NAD+ in muscles of SBMA mouse models, we tested the therapeutic potential of NAD+ restoration in vivo by treating postsymptomatic transgenic SBMA mice with the NAD+ precursor nicotinamide riboside (NR). NR supplementation failed to alter disease progression and had no effect on increasing NAD+ or ATP content in muscle, despite producing a modest increase of …

Gastrointestinal Symptoms In The Peri- And Postmenopause: A Protocol For A Scoping Review, Naomi Shaw, Clare Pettinger

School of Health Professions

Objective:This scoping review aims to systematically map research on gastrointestinal (GI) symptoms in the peri- and postmenopause, with consideration of the extent of available evidence, how research has been conducted, and the variables studied that could influence women’s experiences of GI symptoms.IntroductionPerimenopause is a phase that starts before a woman’s final menstrual period and ends 12 months afterwards. This phase has been associated with a range of symptoms that may impact quality of life. However, researchers argue there are significant gaps in knowledge about (peri)menopause, with GI symptoms proposed as one such area of uncertainty. Exploratory searches identified studies with …

Basal progenitor cells serve as a stem cell pool to maintain the homeostasis of the epithelium of the foregut, including the esophagus and the forestomach. Aberrant genetic regulation in these cells can lead to carcinogenesis, such as squamous cell carcinoma (SCC). However, the underlying molecular mechanisms regulating the function of basal progenitor cells remain largely unknown. Here, we use mouse models to reveal that Hippo signaling is required for maintaining the homeostasis of the foregut epithelium and cooperates with p53 to repress the initiation of foregut SCC.

High Clinical Exome Sequencing Diagnostic Rates And Novel Phenotypic Expansions For Nonisolated Microphthalmia, Anophthalmia, And Coloboma, Bhavana Kunisetty, Bailey A Martin-Giacalone, Xiaonan Zhao, Pamela N Luna, Brian P Brooks, Robert B Hufnagel, Chad A Shaw, Jill A Rosenfeld, A J Agopian, Philip J Lupo, Daryl A Scott

Faculty, Staff and Student Publications

PURPOSE: A molecular diagnosis is only made in a subset of individuals with nonisolated microphthalmia, anophthalmia, and coloboma (MAC). This may be due to underutilization of clinical (whole) exome sequencing (cES) and an incomplete understanding of the genes that cause MAC. The purpose of this study is to determine the efficacy of cES in cases of nonisolated MAC and to identify new MAC phenotypic expansions.

METHODS: We determined the efficacy of cES in 189 individuals with nonisolated MAC. We then used cES data, a validated machine learning algorithm, and previously published expression data, case reports, and animal models to determine …

Eef1a2 Promotes Pten-Gsk3Β-Scf Complex-Dependent Degradation Of Aurora Kinase A And Is Inactivated In Breast Cancer, Warapen Treekitkarnmongkol, Luisa M Solis, Deivendran Sankaran, Mihai Gagea, Pankaj K Singh, Ragini Mistry, Tristian Nguyen, Kazuharu Kai, Jiajun Liu, Kaori Sasai, Yoshimi Jitsumori, Jianwen Liu, Norio Nagao, Fabio Stossi, Michael A Mancini, Ignacio I Wistuba, Alastair M Thompson, Jonathan M Lee, Juan Cadiñanos, Kwong-Kwok Wong, Catherine M Abbott, Aysegul A Sahin, Suyu Liu, Hiroshi Katayama, Subrata Sen

The translation elongation factor eEF1A promotes protein synthesis. Its methylation by METTL13 increases its activity, supporting tumor growth. However, in some cancers, a high abundance of eEF1A isoforms is associated with a good prognosis. Here, we found that eEF1A2 exhibited oncogenic or tumor-suppressor functions depending on its interaction with METTL13 or the phosphatase PTEN, respectively. METTL13 and PTEN competed for interaction with eEF1A2 in the same structural domain. PTEN-bound eEF1A2 promoted the ubiquitination and degradation of the mitosis-promoting Aurora kinase A in the S and G2 phases of the cell cycle. eEF1A2 bridged the interactions between the SKP1-CUL1-FBXW7 (SCF) ubiquitin …

Proteomic Associations Of Adverse Outcomes In Human Heart Failure, Marie-Joe Dib, Ahmed Diab, Ali Javaheri, Douglas L Mann, Et Al.

2020-Current year OA Pubs

BACKGROUND: Identifying novel molecular drivers of disease progression in heart failure (HF) is a high-priority goal that may provide new therapeutic targets to improve patient outcomes. The authors investigated the relationship between plasma proteins and adverse outcomes in HF and their putative causal role using Mendelian randomization.

METHODS AND RESULTS: The authors measured 4776 plasma proteins among 1964 participants with HF with a reduced left ventricular ejection fraction enrolled in PHFS (Penn Heart Failure Study). Assessed were the observational relationship between plasma proteins and (1) all-cause death or (2) death or HF-related hospital admission (DHFA). The authors replicated nominally significant …

Financial And Sovereign Debt Crises: Some Lessons Learned And Those Forgotten, Carmen M. Reinhart, Kenneth S. Rogoff

Journal of Banking and Financial Economics

Even after one of the most severe multi-year crises on record in the advanced economies, the received wisdom in policy circles clings to the notion that high-income countries are completely different from their emerging market counterparts. The current phase of the official policy approach is predicated on the assumption that debt sustainability can be achieved through a mix of austerity, forbearance and growth. The claim is that advanced countries do not need to resort to the standard toolkit of emerging markets, including debt restructurings and conversions, higher inflation, capital controls and other forms of financial repression. As we document, this …

Trade Policy Barriers: An Obstacle To Export Diversification In Eurasia, Ana Paula Paula Cusolito, Claire H. Hollweg

Journal of Banking and Financial Economics

Despite trade liberalization efforts made by Eurasian countries, the export structure of the region shows significant levels of concentration across export destinations. To shed light on this observation, this research analyzes trade policy barriers in Eurasia, East Asia and the Pacific, and the European Union. Using the most recent data from sources including the World Trade Organization, the United Nations, and the World Bank – including the Overall Trade Restrictiveness Indices, the Services Trade Restrictions Database, and the Temporary Trade Barriers Database – the role of tariffs, non-tariff measures, temporary trade barriers, trade agreements, and trade barriers in services are …

Spotting Bubbles: A Two-Pillar Framework For Policy Makers, Bradley A. Jones

Journal of Banking and Financial Economics

In the aftermath of the global financial crisis, the issue of how best to identify speculative bubbles remains in flux. This owes to the difficulty of disentangling irrational investor exuberance from the rational response to lower risk, based on price behavior alone. In response, I introduce a two- pillar (price and quantity) approach for financial market surveillance. While asset pricing models comprise a valuable component of the surveillance toolkit, risk taking behavior, and financial vulnerabilities more generally, can also be reflected in subtler, non-price terms. Though policy makers will always encounter uncertainty when attempting to measure imbalances in financial markets, …

Animal Spirits And Risk In Financial Markets, Jukka Ilomäki

Journal of Banking and Financial Economics

Keynes argues that a beauty contest in financial markets is a combination of rational higher-order beliefs and market psychology or animal spirits. We find that a stable equilibrium, where also market psychology is included, can be possible if uninformed investors agree to reduce their required rate of return indicating that they enlarge the risk of their investment with the animal spirits component.
