Cancers often overexpress multiple clinically relevant oncogenes, but it is not known if combinations of oncogenes in cellular subpopulations within a cancer influence clinical outcomes. Using quantitative multispectral imaging of the prognostically relevant oncogenes MYC, BCL2, and BCL6 in diffuse large B-cell lymphoma (DLBCL), we show that the percentage of cells with a unique combination MYC+BCL2+BCL6- (M+2+6-) consistently predicts survival across four independent cohorts (n = 449), an effect not observed with other combinations including M+2+6+. We show that the M+2+6- percentage can be mathematically derived from quantitative measurements of the individual oncogenes and correlates with survival in IHC (n …

Neoadjuvant FOLFIRINOX and gemcitabine/nab-paclitaxel (GemNP) therapies are increasingly used to treat patients with pancreatic ductal adenocarcinoma (PDAC). However, limited data are available on their clinicopathologic prognosticators. We examined the clinicopathologic factors and survival of 213 PDAC patients who received FOLFIRINOX with 71 patients who received GemNP. The FOLFIRINOX group was younger (p < 0.01) and had a higher rate of radiation (p = 0.049), higher rate of borderline resectable and locally advanced disease (p < 0.001), higher rate of Group 1 response (p = 0.045) and lower ypN stage (p = 0.03) than the GemNP group. Within FOLFIRINOX group, radiation was associated with decreased lymph node metastasis (p = 0.01) and lower ypN …

Although midlobular hepatocytes in zone 2 are a recently identified cellular source for liver homeostasis and regeneration, these cells have not been exclusively fate mapped. We generated an Igfbp2-CreER knockin strain that specifically labels midlobular hepatocytes. During homeostasis over 1 year, zone 2 hepatocytes increased in abundance from occupying 21%-41% of the lobular area. After either pericentral injury with carbon tetrachloride or periportal injury with 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC), IGFBP2+ cells replenished lost hepatocytes in zones 3 and 1, respectively. IGFBP2+ cells also preferentially contributed to regeneration after 70% partial hepatectomy, as well as liver growth during pregnancy. Because IGFBP2 labeling increased …

Low-Load X High-Load Resistance Exercise: Greater Cell Swelling After A Training Session, Gabriel Agentilho, Erick Lucena, Luis Felipe M. Teixeira, Vanessa Boas, Isadora Ribeiro, Renato Barroso, Brad Schoenfeld, Marco Uchida

International Journal of Exercise Science

International Journal of Exercise Science 16(3): 513-524, 2023. Cell swelling caused by resistance training is proposed to provide an anabolic stimulus for muscle growth and it is believed that these effects are heightened with the use of low loads. The purpose of this study was to compare the acute effects of two volume-equated resistance training (RT) protocols, low-load (LL) versus high-load (HL), on elbow flexor muscles thickness, arm circumference, and blood lactate concentration in well-trained individuals. Eight resistance-trained males performed the following two RT protocols involving unilateral elbow flexion of the dominant arm: i) LL, four sets with 50% 1 …

Discovering Distinct Patterns Of Alpha Activity In Adults With Inattentive Adhd Using Electroencephalography, Lucy Salter '23

Senior Scholarly and Creative Symposium

According to data collected and analyzed by researchers, it has been estimated that roughly 8.7 million adults live with attention-deficit/hyperactivity disorder (ADHD), resulting in an estimated $122.8 billion in excess societal costs due to increased healthcare costs, unemployment, and loss of productivity all of which are linked to ADHD symptoms (Schein et al., 2022). Additionally, literature suggests that adult ADHD is associated with increased risk of imprisonment and substance abuse, decreased educational achievement, increased comorbid psychiatric conditions, and poorer clinical outcomes (Ginsberg et al., 2014). Although there is a relatively clearer understanding about ADHD in adolescents, particularly the hyperactive ADHD …

IGC Proceedings (1977-2023)

Hymenachne amplexicaluis [( Rudge ) Nees; 2n= 2x= 24; Azuche, West Indian marsh grass] is a native Central and South America C₃ grass that grows well under intermittent flooding conditions. It produces good seed set and stolons to thrive on new areas assuring its survival, combined with an efficient N metabolism to promote vigorous new growing leaves and tillers (Antel et al., 1998). Azuche is a dual attribute species when introduced to new areas; it has valuable forage attributes but also is a potential weed (Hill, 2000). As Azuche is a native species, one must deal with in …

Critical Analysis Of Tropical Forage Breeding In Brazil, J. A. Usberti Jr., P. B. Alcantara

IGC Proceedings (1977-2023)

Forage grasses account for 90% of the Brazilian forage seed market while the genera Brachiaria, Panicum and others are responsible for 85, 10 and 5% of the traded grass seeds, respectively. Most of the forage grass and legume cultivars available for sowing in Brazil were selected in germplasm banks during the last 20 years, while few of them were derived from artificial crossings, followed by selection for desirable forage traits. The selection of new genetic materials in germplasm banks (exploitation of naturally-occurring genetic variability) is still feasible but the chances of success are decreasing through time. From now on, …

Producer Long-Term Marketing Opportunities With Ethanol Plants, Austin Harthoorn, Logan Lloyd, Cory Walters, Kate Brooks

Cornhusker Economics

Commodity marketing operates in a complex decision environment with constant information flow, which can conceal long-run financially profitable marketing opportunities for producers. In the corn marketing space, the competitive role of ethanol plants throughout the state may provide producers with long-run financial gains by strategically approaching marketing decisions. In this article, we characterize whether producers can gain financially from strategically marketing corn to ethanol plants. For example, do ethanol plants provide a better long-run return from pre-harvest hedging, spring sale, or harvest sale?

We investigate three important contracting times--forward contract for harvest delivery (called pre-harvest hereafter), harvest delivery, and spring …

Single Nucleotide Polymorphisms In Plasmodium Falciparum Genes: Their Roles In Antimalarial Drugs Resistance And Recent Detection Strategies, Raihanny Andrea Zahra, Ananda Maulana Fanshur, Aurelia Maria Prajna Saraswati, Nurul Inayah Rahmani

Indonesian Journal of Medical Chemistry and Bioinformatics

Introduction: Malaria is a serious tropical disease with Plasmodium falciparum as its most well-known causative parasite for producing higher levels of late stage parasites that leads to sequestration in vital organs which could lead to death. There is a growing trend of antimalarial drugs resistance against Plasmodium falciparum. Molecular assessment using polymerase chain reaction could trace the presence of mutation and also determine single-nucleotide polymorphism (SNP) in Plasmodium falciparum genes. This SNP can determine the particular population’s response to antimalarial drugs. Objectives: This study aims to examine the relationship between SNP in Plasmodium falciparum genes and antimalarial drugs resistance. …

Growth, Morphological, And Biochemical Responses Of Four Native Species To Salinity Stress, Asmita Paudel, Youping Sun

Plants, Soils, and Climate Faculty Publications

Native plants are of great value in landscape maintenance. Despite their importance in the landscape, the salt tolerance of most native plants has received little attention. The present research was designed to assess morphological, physiological, and biochemical responses of four Utah-native plants [Arctostaphylos uva-ursi (kinnikinnick), Cercocarpus ledifolius (curl-leaf mountain mahogany), Cercocarpus montanus ‘Coy’ (alder-leaf mountain mahogany), and Shepherdia ×utahensis ‘Torrey’ (hybrid buffaloberry)] at different salinity levels. Each species was irrigated with a nutrient solution at an electrical conductivity (EC) of 1.2 dS·m^-1 (control) or saline solutions at ECs of 5.0 or 10.0 dS·m^-1 for 8 …

What Are The Impacts Of Deer Browsing And Japanese Stiltgrass (Microstegium Vinenium) On Native Sapling Growth In A Residential Wetland In Southeastern Georgia?, Josie Richards

Honors College Theses

Wetlands promote biodiversity, act as climate stabilizers, and regulate water flow, yet are vulnerable to invaders. An invasive species can affect the biodiversity, abiotic conditions, and increase vulnerability of an ecosystem over time and deer browsing can actively affect new growth by removing the apical buds of young woody vegetation. Japanese stiltgrass (Microstegium vimineum), a wetland specific invader, has been shown to compete against native species for limited resources and actively crowd them out. Growth of native saplings can be further complicated by the presence of white tailed deer (Odocoileus virginianus), which browse woody vegetation and limit recruitment of trees. …

Clinical Outcomes Of Immunotherapy Continued Beyond Radiographic Disease Progression In Older Adult Patients With Advanced Non-Small Cell Lung Cancer, Eric K Singhi, Frank Mott, Michelle Worst, Cheuk Hong Leung, J Jack Lee, Brett Carter, Carolyn J Presley, John V Heymach, Mehmet Altan

Faculty, Staff and Student Publications

Immunotherapy is an effective and generally well-tolerated treatment strategy for older adult patients (aged ≥70 years) with advanced non-small cell lung cancer (NSCLC). Unfortunately, most patients who receive immunotherapy eventually exhibit disease progression during treatment. The present study reports on a subset of older adult patients with advanced NSCLC who could effectively continue immunotherapy beyond radiographic disease progression due to perceived clinical benefit. Local consolidative radiotherapy may be used in select older adult patients to prolong the duration of immunotherapy they receive, with a particular consideration of their preexisting co-morbidities, performance status and tolerance of potential toxicities associated with combined …

Chemically Catalyzed Phytoextraction For Sustainable Cleanup Of Soil Lead Contamination In A Community Garden In Jersey City, New Jersey, Zhiming Zhang, Dibyendu Sarkar, Frances Levy, Rupali Datta

Michigan Tech Publications, Part 1

Soil lead (Pb) contamination in Pb paint-contaminated homes is a serious health risk in urban areas. Phytoextraction is a green and sustainable technology for soil Pb remediation, but its efficiency depends on the geochemical partitioning of Pb in soil. Following successful laboratory, greenhouse, and panel experiments, a field study was conducted to demonstrate the effectiveness of a chemically catalyzed phytoextraction model for Pb removal. A biodegradable chelating agent, ethylenediaminedisuccinic acid (EDDS) was applied during Pb phytoextraction by vetiver grass (Chrysopogon zizanioides) in a Pb-contaminated community garden in Jersey City, New Jersey. Results showed that soil Pb concentration was reduced from …

A Sister-Group Comparison Of Branching And Pedicellariae In Brittlestar S (Echinodermata: Ophiuroidea), Richard L. Turner, Brenna O. O'Neill

Ocean Engineering and Marine Sciences Faculty Publications

Branching of arms and presence of pedicellariae are characters among ophiuroids found only in the order Euryalida (snakestars and basketstars). Family Asteronychidae has neither character; family Euryalidae has 2 small clades with branched arms; and family Gorgonocephalidae has all species with pedicellariae and 3 or 4 clades with branched arms. Despite the rare occurrence of these characters in the Ophiuroidea, they might be key adaptations within the Euryalida that have led to relatively high diversification. Sister-group comparison of the distribution of these 2 characters among taxa indicates that neither character alone explains diversity patterns within the order. In particular, branching …

A Review Of Propagation And Restoration Techniques For American Beech And Their Current And Future Application In Mitigation Of Beech Bark Disease, Andrea L. Myers, Andrew J. Storer, Yvette L. Dickinson, Tara Bal

Michigan Tech Publications, Part 1

The American beech (Fagus grandifolia Ehrh.) has been impacted by the beech bark disease (BBD) complex throughout the northeastern United States for over 100 years, but the disease has been present in the Great Lakes region only for around 20 years, requiring acknowledgement of the evolving context surrounding F. grandifolia. This disease threatens to remove a foundational tree species which is especially important ecologically for wildlife habitat and mast, and as a climax successional species. We review advances in propagation techniques of F. grandifolia with the goal of addressing their use in the rehabilitative restoration of forests affected by BBD. …

Impact Of Clonal Plasma Cells In Autografts On Outcomes In High-Risk Multiple Myeloma Patients, Oren Pasvolsky, Denái R Milton, Mikael Rauf, Sassine Ghanem, Adeel Masood, Ali H Mohamedi, Mark R Tanner, Qaiser Bashir, Samer Srour, Neeraj Saini, Paul Lin, Jeremy Ramdial, Yago Nieto, Guilin Tang, Hans C Lee, Krina K Patel, Partow Kebriaei, Sheeba K Thomas, Donna M Weber, Robert Z Orlowski, Katy Rezvani, Richard Champlin, Elizabeth J Shpall, Pei Lin, Muzaffar H Qazilbash

Most patients with multiple myeloma (MM) undergoing autologous hematopoietic stem cell transplantation (autoHCT) eventually relapse, perhaps due to the presence of clonal plasma cells (CPC) in the autograft. We conducted a retrospective analysis to evaluate the impact of CPC in the autograft on the outcomes of high-risk chromosomal abnormalities (HRMM) patients undergoing autoHCT between 2008 and 2018. Patients were divided into CPC+ or CPC- in the autograft by next-generation flow cytometry (NGF). There were 75 CPC + autografts (18%) and 341 CPC- (82%). The CPC + group was less likely to achieve MRD-negative complete remission post-transplant (11% vs. 42%; p < 0.001). Median progression free survival (PFS) and overall survival (OS) were (12.8 vs. 32.1 months) and (36.4 vs. 81.2 months) in the CPC + and CPC- groups, respectively (both p < 0.001). Also in the subset of patients with MRD-negative ≥VGPR prior to autoHCT, those with CPC + autografts had inferior PFS (HR 4.21, p = 0.006) and OS (HR 7.04, p = 0.002) compared to CPC-. In multivariable analysis, the degree of CPC positivity in the autograft was independently predictive of worse PFS (HR 1.50, p = 0.001) and OS (HR 1.37, p = 0.001). In conclusion, both the presence and degree of CPC in the autograft were highly predictive of inferior PFS and OS.

Patients with BRAF-mutant melanoma show substantial responses to combined BRAF and MEK inhibition, but most relapse within 2 years. A major reservoir for drug resistance is minimal residual disease (MRD), comprised of drug-tolerant tumor cells laying in a dormant state. Towards exploiting potential therapeutic vulnerabilities of MRD, we established a genetically engineered mouse model of BrafV600E-driven melanoma MRD wherein genetic BrafV600E extinction leads to strong but incomplete tumor regression. Transcriptional time-course analysis after BrafV600E extinction revealed that after an initial surge of immune activation, tumors later became immunologically "cold" after MRD establishment. Computational analysis identified candidate T-cell recruiting chemokines as …

Temporal Changes In Biological Community Structure In Response To Wetland Restoration: A Study Based On Amphibians And Reptiles, Kayla Keith

Honors Program Theses and Projects

Wetland degradation is a serious environmental concern worldwide. In the United States, over half of the wetland ecosystems have degraded since 1780, which can have numerous, lasting consequences with negative outcomes on ecosystems and human society alike. Ecological restoration can regain both the lost wetland acreage and functions. Both global and national scale interests in ecological restoration have trickled down, which has kindled the local and regional natural resource managers and conservation authorities to invest in restoration. Consequently, large-scale wetland restoration projects are now underway in southeastern Massachusetts, which has coincided with a decline in commercial cranberry farming in the …

Objectives

The aim of this study was to investigate if commonly requested blood tests could indicate MM in primary care and potentially lead to earlier diagnosis.

Design and Methods

This retrospective observational study involved an audit of clinical and laboratory data from 109 MM patients, including patients with Active MM (N = 53), Smouldering MM …

(Pro)Renin Receptor And Its Soluble Form In Metabolic Dysfunction: Friend Or Foe?, Gertrude Arthur

Journal of Pharmacology & Nutritional Sciences

(Pro)renin receptor is component of the renin angiotensin system which has been shown to be involved in several physiological and pathophysiological processes including blood pressure regulation and hypertension, water and electrolyte balance, kidney injury, obesity, and metabolic dysfunction. Enzymatic cleavage of prorenin receptor produces soluble prorenin receptor which can also activate the renin angiotensin system stimulate similar pathophysiological process like its full form receptor. This review explores findings on the role of prorenin receptor and soluble prorenin receptor in metabolic dysfunction and discusses the conflicting findings on soluble prorenin receptor in metabolic dysfunction.

Although how climate change impacts mosquitoes of the tropical world has been explored, temperate areas remain inadequately studied. Therefore, the medical and healthcare sectors are underprepared for treating mosquito-borne diseases (EEE and Western Nile virus). Based on a long-term ecological dataset covering the past ~10 years across 45 sites, we streamlined, processed, and subsequently analyzed data by building statistical models to understand changes among mosquito populations in the US in response to climate …

Reverse Genetics: Downregulating Chk-1 And Fasn-1 In The Gonads Of C. Elegans, Sam Thompson

Undergraduate Theses

Despite its widespread use in research, the model organism C. elegans has several biological processes like gonadal development with potentially unexplored genetic regulators. Previous transcriptome analysis has identified several genes that are upregulated in a specific tissue or sex during the development of the somatic gonad in C. elegans (Kroetz et al. 2015) that have not been previously connected to this process. Of these genes, this research is concerned with chk-1 and fasn-1. Abrogating the expression of these genes in gonadal tissue during gonadogenesis could cause a change in phenotype for affected C. elegans that would aid in understanding these …
