Faculty, Staff and Student Publications

Over 250,000 gastrostomy tubes (G-tubes) are placed annually in the United States. Percutaneous endoscopic gastrostomy (PEG) is the most widely used clinical method for placing G-tubes within the stomach. However, endoscope detectability is limited due to the scattering of light by tissues. Poor organ visibility and low sensitivity of the palpation techniques cause blind needle insertions, which cause colon/liver perforations, abdominal bleeding, and gastric resections. Additionally, imaging artifacts and the poor distinguishability between water-filled tissues make ultrasound (US) imaging-based techniques incompatible with G-tube placement. The risk of ionizing radiation exposure and the confinement of fluoroscopy to radiology suites limits its …

Coastal Environments: Lidar Mapping Of Copper Tailings Impacts, Particle Retention Of Copper, Leaching, And Toxicity, W. Charles Kerfoot, Gary Swain, Robert Regis, Varsha K. Raman, Colin N. Brooks, Chris Cook, Et. Al.

Michigan Tech Publications

Tailings generated by mining account for the largest world-wide waste from industrial activities. As an element, copper is relatively uncommon, with low concentrations in sediments and waters, yet is very elevated around mining operations. On the Keweenaw Peninsula of Michigan, USA, jutting out into Lake Superior, 140 mines extracted native copper from the Portage Lake Volcanic Series, part of an intercontinental rift system. Between 1901 and 1932, two mills at Gay (Mohawk, Wolverine) sluiced 22.7 million metric tonnes (MMT) of copper-rich tailings (stamp sands) into Grand (Big) Traverse Bay. About 10 MMT formed a beach that has migrated 7 km …

Scupa: Single-Cell Unified Polarization Assessment Of Immune Cells Using The Single-Cell Foundation Model, Wendao Liu, Zhongming Zhao

Faculty, Staff and Student Publications

MOTIVATION: Immune cells undergo cytokine-driven polarization in response to diverse stimuli, altering their transcriptional profiles and functional states. This dynamic process is central to immune responses in health and diseases, yet a systematic approach to assess cytokine-driven polarization in single-cell RNA sequencing data has been lacking.

RESULTS: To address this gap, we developed single-cell unified polarization assessment (Scupa), the first computational method for comprehensive immune cell polarization assessment. Scupa leverages data from the Immune Dictionary, which characterizes cytokine-driven polarization states across 14 immune cell types. By integrating cell embeddings from the single-cell foundation model Universal Cell Embeddings, Scupa effectively identifies …

Culturable Microbial Communities In Root Nodules Of Red Alder (Alnus Rubra Bong.) And Scotch Broom (Cytisus Scoparius L.): Patterns Of Diversity And Composition, Felisha (Fay) Rene Pooler

Dissertations and Theses

Endophytes are a hyper diverse group of bacterial or fungal organisms residing within plant tissues without causing visible symptoms of disease. While their overall diversity and ecological functions are not well-understood, some endophytes can provide a range of important benefits to their host such as enhanced growth and increased tolerance to environmental stress. Nitrogen-fixing bacteria residing within nodules--specialized structures on the roots of legumes and actinorhizal plants--play an integral role in the plant microbiome by facilitating nitrogen availability in nutrient-poor environments. Remarkably, the patterns of diversity including both bacterial and fungal endophytes in root nodules are virtually known, except in …

Depletion or inhibition of core stress granule proteins, G3BP1 in mammals and TIAR-2 in Caenorhabditis elegans, increases the growth of spontaneously regenerating axons. Inhibition of G3BP1 by expression of its acidic or “B-domain” accelerates axon regeneration after nerve injury, bringing a potential therapeutic strategy for peripheral nerve repair. Here, we asked whether G3BP1 inhibition is a viable strategy to promote regeneration in injured mammalian central nervous system (CNS) where axons do not regenerate spontaneously. G3BP1 B-domain expression was found to promote axon regeneration in the transected spinal cord provided with a permissive peripheral nerve graft (PNG) as well as in …

Learning Directed Acyclic Graphs For Ligands And Receptors Based On Spatially Resolved Transcriptomic Data Of Ovarian Cancer, Shrabanti Chowdhury, Sammy Ferri-Borgogno, Peng Yang, Wenyi Wang, Jie Peng, Samuel C Mok, Pei Wang

Faculty, Staff and Student Publications

To unravel the mechanism of immune activation and suppression within tumors, a critical step is to identify transcriptional signals governing cell-cell communication between tumor and immune/stromal cells in the tumor microenvironment. Central to this communication are interactions between secreted ligands and cell-surface receptors, creating a highly connected signaling network among cells. Recent advancements in in situ-omics profiling, particularly spatial transcriptomic (ST) technology, provide unique opportunities to directly characterize ligand-receptor signaling networks that power cell-cell communication. In this paper, we propose a novel statistical method, LRnetST, to characterize the ligand-receptor interaction networks between adjacent tumor and immune/stroma cells based on ST …

Proteomics Of Extracellular Vesicles: Recent Updates, Challenges And Limitations, Mohini Singh, Prashant Kumar Tiwari, Vivek Kumar Kashyap, Sanjay Kumar

School of Medicine Publications

Extracellular vesicles (EVs) are lipid-bound vesicles secreted by cells, including exosomes, microvesicles, and apoptotic bodies. Proteomic analyses of EVs, particularly in relation to cancer, reveal specific biomarkers crucial for diagnosis and therapy. However, isolation techniques such as ultracentrifugation, size-exclusion chromatography, and ultrafiltration face challenges regarding purity, contamination, and yield. Contamination from other proteins complicates downstream processing, leading to difficulties in identifying biomarkers and interpreting results. Future research will focus on refining EV characterization for diagnostic and therapeutic applications, improving proteomics tools for greater accuracy, and exploring the use of EVs in drug delivery and regenerative medicine.

Research Symposium

Metarrestin (ML246) is an orally bioavailable synthetic molecule that selectively disrupts the perinucleolar compartment (PNC) structure, and it has showed promise in preclinical studies for metastatic cancer therapy. However, the precise molecular mechanism of ML246 remains poorly understood. We investigated the topological and protein interaction network (PIN) analyses of ML246 to determine the molecular mechanism of ML246. To determine the regulatory effect of ML246 on the rewired PIN of ML246, an intercom was constructed using 25 oncogenic key proteins. These proteins were selected using the reverse pharmacophore matching approach (based on a fit score > 0.502) using the STRING database and …

A Time For Change- Issues Arising From The Xvii International Grassland Congress Developed World Viewpoint, Barney Foran

IGC Proceedings (1977-2023)

A number of major issues raised at the conference, if they are accepted by farmers and grassland scientists, will mean a major realignment of both the philosophy and practice of grassland science. The first of these is future world trade flows and a bleak prognosis for traded livestock products. Jf the developed world accepts that developing nations have to trade in order to develop, and trade in commodities where they have a cost advantage, this suggests that bulk production of livestock commodities will decline ln total. Thus grassland exports will have to concentrate on high value niche markets. This poses …

Deforestation In Pakistan, Inayat U. Chaudhry

IGC Proceedings (1977-2023)

Pakistan's economy is agricultural and pastoral. From 1150 to 1991 its forest cover declined from an estimated 28 million ha to 4,6 million ha and population increased from 1.2 to 112 million. rn addition to. increasing population, government irrigation projects for colonisation, in road of agriculture into forestry and construction of barrages over rivers caused deforestation. This has increased soil erosion, siltation of dams and the gap in production and demand of wood: biodiversity has been adversely affected and mangrove forests have degraded. Forestation has been carried out over 220 000 ha since 1947. A network of easily accessible nurseries, …

Animal Production From Tropical Semi-Arid Savannah Woodland In Subcoastal Queensland, Australia, H G. Bishop, H J. Chamberlain, R M. Dodt, T B. Hilder, G A. Lambert, E R. Anderson

IGC Proceedings (1977-2023)

Annual live-weight gain of steers grazing on virgin tropical semi­arid poplar box (Eucalyptus populnea) savannah woodland in subcoastal central Queensland fluctuated between 59 kg/head and 200 kg/head over a 7-year period. Average live-weight gain for the 7 years was 136 kg/head/year, which is above expected levels for this vegetation type. Reasons suggested for this animal performance are the use of a stocking rate more lenient than the district average and above-average winter rainfall received during the 7 years of this demonstration project. Removing trees doubled the pasture dry matter yield, which subsequently allowed a doubling of stocking rate …
