Beef Steer Performance On Irrigated Monoculture Legume Pastures Compared With Grass-And Concentrate-Fed Steers, Lance R. Pitcher, Jennifer W. Macadam, Robert E. Ward, Kun Jun Han, Thomas C. Griggs, Xin Dai Apr 2022

Beef Steer Performance On Irrigated Monoculture Legume Pastures Compared With Grass-And Concentrate-Fed Steers, Lance R. Pitcher, Jennifer W. Macadam, Robert E. Ward, Kun Jun Han, Thomas C. Griggs, Xin Dai

Faculty Publications

Fall-or spring-born steers grazed monoculture irrigated birdsfoot trefoil (BFT; Lotus corniculatus L.) or cicer milkvetch (CMV; Astragalus cicer L.) pastures for approximately 12 weeks for 3 years and were compared with steers on concentrate diets. In the 3rd year, an irrigated meadow bromegrass (MBG; Bromus biebersteinii Roem. and Schult.) pasture treatment was added for further comparison. Steer average daily gain (ADG) was 1.31, 0.94, 0.83 and 0.69 kg d−1 on concentrate, ‘Norcen’ BFT, ‘Oberhaunstadter’ BFT, and ‘Monarch’ CMV diets, respectively; ADG on grass pastures was 0.43 kg d−1. The ADG on the concentrate diet was greater than ADG on legume …

In streams, unionoid mussels and fish form aggregations that exert bottom-up and top-down effects on food webs, but the magnitude and spatial extent of their effects are controlled by species traits. Sedentary mussels live burrowed in the sediment in patchily distributed dense aggregations (mussel beds) where they filter seston and provide a local, relatively constant nutrient subsidy. In contrast, fish move on and off mussel beds, and thus comprise a transient nutrient subsidy. We asked how overlap between fish and mussels influences nutrient recycling and resource distribution in streams. We conducted an 8-week study in experimental streams where we created …

Non-alcoholic steatohepatitis (NASH) is a clinically important spectrum of non-alcoholic fatty liver disease (NAFLD) in humans. NASH is a stage of NAFLD progression wherein liver steatosis accompanies inflammation and pro-fibrotic events. Presently, there are no approved drugs for NASH, which has become a leading cause of liver transplant worldwide. To discover novel drug targets for NASH, we analyzed a human transcriptomic NASH dataset and found Aldo-keto reductase family 1 member B10 (AKR1B10) as a significantly upregulated gene in livers of human NASH patients. Similarly murine Akr1b10 and Aldo-keto reductase family 1 member B8 (Akr1b8) gene, which is a murine ortholog …


Beyond Appetite Regulation: Targeting Energy Expenditure, Fat Oxidation, And Lean Mass Preservation For Sustainable Weight Loss, Berit Østergaard Christoffersen, Guillermo Sanchez-Delgado, Linu Mary John, Donna H. Ryan, Kirsten Raun, Eric Ravussin Apr 2022

Beyond Appetite Regulation: Targeting Energy Expenditure, Fat Oxidation, And Lean Mass Preservation For Sustainable Weight Loss, Berit Østergaard Christoffersen, Guillermo Sanchez-Delgado, Linu Mary John, Donna H. Ryan, Kirsten Raun, Eric Ravussin

Clinical Research Faculty Publications

New appetite-regulating antiobesity treatments such as semaglutide and agents under investigation such as tirzepatide show promise in achieving weight loss of 15% or more. Energy expenditure, fat oxidation, and lean mass preservation are important determinants of weight loss and weight-loss maintenance beyond appetite regulation. This review discusses prior failures in clinical development of weight-loss drugs targeting energy expenditure and explores novel strategies for targeting energy expenditure: mitochondrial proton leak, uncoupling, dynamics, and biogenesis; futile calcium and substrate cycling; leptin for weight maintenance; increased sympathetic nervous system activity; and browning of white fat. Relevant targets for preserving lean mass are also …


Financial Challenges And Capacity Among African Refugees In The Southern Usa: A Study Of Socio-Demographic Differences, Njeri Kagotho, Jennifer Scott, Mckenzie M. Ketchum, Youn Kyoung Kim, Arati Maleku, Younghee Lim Apr 2022

Financial Challenges And Capacity Among African Refugees In The Southern Usa: A Study Of Socio-Demographic Differences, Njeri Kagotho, Jennifer Scott, Mckenzie M. Ketchum, Youn Kyoung Kim, Arati Maleku, Younghee Lim

Faculty Publications

Refugees’ successful integration into US society requires adaptation to economic, financial and social norms. Despite the importance of considering financial challenges (financial stress and financial anxiety) and financial capacity (financial literacy and financial self-efficacy) in reaching personal financial goals, literature examining the relationship between financial challenges and capacity—critical in refugee resettlement and integration—is sparse and fragmented. This study explored financial challenges and capacity amongst resettled African refugees (N ¼ 130) in the southern USA using data from a larger community-based participatory research study that used a mixed-methods approach. We explored socio-demographic differences in financial stress, financial anxiety, financial literacy and …


Exercise As A Moderator Of Persistent Neuroendocrine Symptoms Of Covid-19, Candida J. Rebello, Christopher L. Axelrod, Charles F. Reynolds, Frank L. Greenway, John P. Kirwan Apr 2022

Exercise As A Moderator Of Persistent Neuroendocrine Symptoms Of Covid-19, Candida J. Rebello, Christopher L. Axelrod, Charles F. Reynolds, Frank L. Greenway, John P. Kirwan

Division of Basic Science Faculty Publications

Precipitated by chronic psychological stress, immune system dysregulation, and a hyperinflammatory state, the sequelae of postacute COVID-19 (long COVID) include depression and new-onset diabetes. We hypothesize that exercise counters the neuropsychiatric and endocrine sequelae of long COVID by inducing the release of circulating factors that mediate the anti-inflammatory response, support brain homeostasis, and increase insulin sensitivity.


Sgk1 Is Essential For Meiotic Resumption In Mammalian Oocytes, Edgar Del Llano, Rajan Iyyappan, Daria Aleshkina, Tomas Masek, Michal Dvoran, Zongliang Jiang, Martin Pospisek, Michal Kubelka, Andrej Susor Apr 2022

Sgk1 Is Essential For Meiotic Resumption In Mammalian Oocytes, Edgar Del Llano, Rajan Iyyappan, Daria Aleshkina, Tomas Masek, Michal Dvoran, Zongliang Jiang, Martin Pospisek, Michal Kubelka, Andrej Susor

Faculty Publications

In mammalian females, oocytes are stored in the ovary and meiosis is arrested at the diplotene stage of prophase I. When females reach puberty oocytes are selectively recruited in cycles to grow, overcome the meiotic arrest, complete the first meiotic division and become mature (ready for fertilization). At a molecular level, the master regulator of prophase I arrest and meiotic resumption is the maturation-promoting factor (MPF) complex, formed by the active form of cyclin dependent kinase 1 (CDK1) and Cyclin B1. However, we still do not have complete information regarding the factors implicated in MPF activation. In this study we …

Are Long-Period Exoplants Around Cool Stars More Common Than We Thought?, Emily Jane Safron Mar 2022

Are Long-Period Exoplants Around Cool Stars More Common Than We Thought?, Emily Jane Safron

LSU Doctoral Dissertations

The Kepler mission has been the catalyst for discovery of nearly 5,000 confirmed and candidate exoplanets. The majority of these candidates orbit Sun-like stars, and have orbital periods comparable to or shorter than that of the Earth, due to the selection bias inherent in the transit method and the limitations of automated transit search algorithms. We aim to develop a richer understanding of the population of exoplanets around the lowest-mass stars, the M spectral type. We are particularly interested in exoplanets with long orbital periods, which are difficult or impossible to find using standard transit search algorithms. In our study, …
