Simmons, Douglas E. Long, Kate Kosmac, Cory M. Dungan, Philip A. Kern, Marcas M. Bamman, Charlotte A. Peterson

Center for Muscle Biology Faculty Publications

The extracellular matrix (ECM) in skeletal muscle plays an integral role in tissue development, structural support, and force transmission. For successful adaptation to mechanical loading, remodeling processes must occur. In a large cohort of older adults, transcriptomics revealed that genes involved in ECM remodeling, including matrix metalloproteinase 14 (MMP14), were the most upregulated following 14 weeks of progressive resistance exercise training (PRT). Using single-cell RNA-seq, we identified macrophages as a source of Mmp14 in muscle following a hypertrophic exercise stimulus in mice. In vitro contractile activity in myotubes revealed that the gene encoding cytokine leukemia inhibitory factor ( …

The Directed Steps Of Hans Christian Gram: How Providence Played A Role In The Gram Stain, Which Illumines The Ordered Pattern Of Bacterial Cell Walls And Helps Identify Pathogens Of Infectious Diseases, Alan L. Gillen

Faculty Publications and Presentations

This paper honors Hans Christian Joachim Gram. In published papers, he simply identified as Christian Gram. Gram devised a staining technique that is still used to identify and classify different types of bacteria. He was a Danish microbiologist, born in Copenhagen on September 13, 1853. In German microbiologist Karl Friedländer’s lab, Gram noticed that staining a smear of pneumonia bacteria with a crystal violet followed by iodine and organic solvent showed differences in various samples. “Gram-negative” bacteria have thin cell walls that allow the solvent to wash away part of the stain. “Gram-positive” bacteria appear purple in microscopy because their …

Weather Impacts The Agricultural Production Efficiency Of Wheat: The Importance Of Precipitation Shocks, Bowen Chen, Elliott James Dennis, Allen M. Featherstone

Cornhusker Economics

Weather affects the production environment that farmers face and, in some cases, can affect their ability to efficiently convert production inputs into outputs. Despite that the effect of weather shocks on agricultural production has been well documented (Donaldson, 1968; Ito and Kurosaki, 2009; Schlenker and Roberts, 2009; Tack, Barkley, and Nalley, 2015), few studies have accounted for the weather as a source of production inefficiency or lower agricultural productivity. In a recently published paper, we showed the effects that weather has on the production efficiency of winter wheat farms and discussed some of the implications that climate change could …

Michigan Tech Publications, Part 1

Hypsipyla robusta Moore (Lepidoptera: Pyralidae), like many other moth species, shows selectivity when choosing host plants for its eggs. Four Meliaceae species (Khaya grandifoliola, K. ivorensis, Swietenia macrophyla, and Entandrophragma cylindricum) were established in a moist semideciduous forest in Ghana to study this selectivity at 12 and 21 months after planting. The analysis of variance (ANOVA) at a P-value of 0.05 was used to test the significance of differences in infestation by H. robusta between the species. H. robusta attacks were recorded by month 12 after planting in the field, and only Khaya spp. was attacked, with attacks evident on …

Ecology Of Periphyton In A Subtropical River Floodplain, Kamela De Gallardo

LSU Doctoral Dissertations

The Atchafalaya River Basin (ARB) in southcentral Louisiana, USA, is a large and biologically diverse floodplain surrounding the Atchafalaya River (AR), which is the largest distributary of the Mississippi River, receiving 30% of the combined daily discharge of the Mississippi and Red Rivers. Annual flooding facilitates exchange between the AR and its floodplain and is thought to give rise to the high productivity of the river-floodplain system. Primary production within the aquatic ARB is driven by periphytic algae, phytoplankton, and aquatic macrophytes, however, very little is known about periphytic algal assemblages in floodplain systems. In this study, artificial substrates were …

Prenatal Exposure To Maternal Psychological Distress And Telomere Length In Childhood, Stephanie A. Stout-Oswald, Laura M. Glynn, Marco Bisoffi, Catherine H. Demers, Elysia Poggi Davis

Psychology Faculty Articles and Research

Telomere length (TL) is a biological marker of cellular aging, and shorter TL in adulthood is associated with increased morbidity and mortality risk. It is likely that these differences in TL are established long before adulthood, and there is growing evidence that TL can reflect prenatal experiences. Although maternal prenatal distress predicts newborn TL, it is unknown whether the relation between prenatal exposure to maternal distress and child TL persists through childhood. The purpose of the current longitudinal, prospective study is to examine the relation between prenatal exposure to maternal distress (perceived stress, depressive symptoms, pregnancy-related anxiety) and TL in …

Alfalfa is a very important forage for livestock feeding. In particular, due to the high crude protein content, it is widely used as a dairy cattle feeds. However, the cultivation of alfalfa is quite limited and main source is imported hay in Korea. There are many reasons, but most importantly, low productivity due to lack of boron in the soil. This experiment was conducted to expand domestic production and use of alfalfa. Alfalfa was sown in the fall of 2018 at 30 kg/ha seeding rate. Alfalfa was harvested four times (3 May, 2 July, 11 September and 13 October) in …

Economic Injury Level For Bermudagrass Stem Maggot (Diptera: Muscidae) In Bermudagrass Forage Production In Texas, V. Corriher-Olson, A. Knutson, F. Mitchell

IGC Proceedings (1977-2023)

The bermudagrass stem maggot, Atherigona reversura Villeneuve, was first reported damaging bermudagrass Cynodon dactylon (L.) Pers grown for forage in 2010 in the southeastern US. Damage results from individual larvae feeding internally on the vascular tissue just above the terminal node of the grass stem. Damage slows plant growth and reduces forage accumulation. To address the need for economic guidelines to manage this new pest, the relationship between the percent of stems damaged by bermudagrass stem maggot and forage yield was measured in commercial bermudagrass hay fields in northcentral Texas during 2016 and 2017. The slope of the linear regression, …

Medical College Documents

A 17-year-old female presented to our hospital complaining of bloody diarrhea 4-6 times per day for the past month. She was a known case of inflammatory bowel disease noncompliant to her medications. Abdominal computed tomography revealed an unusually dilated mass in the retroperitoneum at L2 vertebral level connecting the lumbar and left renal veins. The renal artery was visualized separately, and a diagnosis of communicating vein varicosity was made. This lesion can be misleading on imaging, hence our aim to disseminate our findings to practicing radiologists. The differential diagnosis of these lesions include retroperitoneal lymphadenopathy, renal artery aneurysms, and testicular …

Characterizing Human Gut Bacterial Tir Domains In Vitro, In Gnotobiotic Mice And Malnourished Children, James Stephen Weagley

Arts & Sciences Graduate Student Theses and Dissertations

Worldwide, malnutrition (undernutrition) is the leading cause of death in children under 5. Studies of healthy members of birth cohorts from low- and middle-income countries have identified a program of gut microbial community development that is disrupted in children with severe acute malnutrition (SAM) and moderate acute malnutrition (MAM). This perturbed gut microbiome development has been linked to the pathogenesis of malnutrition. Repair of this gut microbial dysbiosis in children with MAM with microbiota-directed complementary foods (MDCFs) designed to increase the fitness and expressed beneficial functions of underrepresented bacterial community members restores healthy growth, including improvements in mediators of metabolic …
