The Ephb2 Receptor Uses Homotypic, Head-To-Tail Interactions Within Its Ectodomain As An Autoinhibitory Control Mechanism, Yan Xu, Dorothea Robev, Nayanendu Saha, Bingcheng Wang, Matthew B. Dalva, Kai Xu, Juha P. Himanen, Dimitar B. Nikolov

Department of Neuroscience Faculty Papers

The Eph receptor tyrosine kinases and their ephrin ligands direct axon pathfinding and neuronal cell migration, as well as mediate many other cell–cell communication events. Their dysfunctional signaling has been shown to lead to various diseases, including cancer. The Ephs and ephrins both localize to the plasma membrane and, upon cell–cell contact, form extensive signaling assemblies at the contact sites. The Ephs and the ephrins are divided into A and B subclasses based on their sequence conservation and affinities for each other. The molecular details of Eph–ephrin recognition have been previously revealed and it has been documented that ephrin binding …

Supercoiling And Looping Promote Dna Base Accessibility And Coordination Among Distant Sites, Jonathan M Fogg, Allison K Judge, Erik Stricker, Hilda L Chan, Lynn Zechiedrich

Faculty, Staff and Students Publications

DNA in cells is supercoiled and constrained into loops and this supercoiling and looping influence every aspect of DNA activity. We show here that negative supercoiling transmits mechanical stress along the DNA backbone to disrupt base pairing at specific distant sites. Cooperativity among distant sites localizes certain sequences to superhelical apices. Base pair disruption allows sharp bending at superhelical apices, which facilitates DNA writhing to relieve torsional strain. The coupling of these processes may help prevent extensive denaturation associated with genomic instability. Our results provide a model for how DNA can form short loops, which are required for many essential …

Thrombolytic Enzymes Of Microbial Origin: A Review, Deepti Diwan, Zeba Usmani, Minaxi Sharma, James W Nelson, Vijay Kumar Thakur, Graham Christie, Gustavo Molina, Vijai Kumar Gupta

2020-Current year OA Pubs

Enzyme therapies are attracting significant attention as thrombolytic drugs during the current scenario owing to their great affinity, specificity, catalytic activity, and stability. Among various sources, the application of microbial-derived thrombolytic and fibrinolytic enzymes to prevent and treat vascular occlusion is promising due to their advantageous cost-benefit ratio and large-scale production. Thrombotic complications such as stroke, myocardial infarction, pulmonary embolism, deep venous thrombosis, and peripheral occlusive diseases resulting from blood vessel blockage are the major cause of poor prognosis and mortality. Given the ability of microbial thrombolytic enzymes to dissolve blood clots and prevent any adverse effects, their use as …

Enhancing Uptake Of Nature-Based Solutions For Informing Coastal Sustainable Development Policy And Planning: A Malaysia Case Study, Su Yin Chee, Louise B.

Aldrie Amir, Chai Ming Lau, Jillian Lean Sim Ooi, Yew Aun Quek, Choo Eng Tan, Tzuen Kiat Yap, Chin Aik Yeap, Abigail Mcquatters-Gollop

School of Biological and Marine Sciences

Nature-based Solutions (NbS) have been advocated to protect, sustainably manage, and restore natural or modified ecosystems, simultaneously providing human well-being and biodiversity benefits. The uptake of NbS differs regionally with some countries exhibiting greater uptake than others. The success of NbS also differs regionally with varying environmental conditions and social-ecological processes. In many regions, the body of knowledge, particularly around the efficacy of such efforts, remains fragmented. Having an “inventory” or “tool box” of regionally-trialed methods, outcomes and lessons learnt can improve the evidence base, inform adaptive management, and ultimately support the uptake of NbS. Using Malaysia as a case …

Eating The Claws Of Eden: Stone Crabs, Tourism, And The Taste Of Conservation In Florida And Beyond, Florida Historical Society

Florida Historical Quarterly

Don't miss the stone crab-it's in season now," counseled Kathryn Loring to her sister before she and her husband made their first trip from Chicago to Florida in February of 1960. Once in Florida, Loring and her husband took her sister's advice, embarking on a self-proclaimed "sea food binge" that included devouring mullet, pompano, New England and Manhattan-style clam chowder, red snapper, shrimp, and, of course, stone crab. They found the "sweet and delectable" claws of stone crab at Hudgins Cafe in West Palm Beach, Florida, where surrounded by other sun-burned tourists they consumed the meat of a crab that …

Apparent Recovery Of Surface Applied Nitrogen Fertilizer By A Coastcross Pasture, A. C. Primavesi, O. Primavesi, L. A. Corrêa, H. Cantarella, A. G. Silva

IGC Proceedings (1977-2023)

Nitrogen recoveries from five levels of urea and ammonium nitrate surface-applied on coastcross pasture, grown on a dark red latosol (Hapludox), in São Carlos, SP, Brazil, under tropical altitude climate, were estimated. Significant differences occurred within periods (P < 0.05), depending on climatic conditions. Under adequate plant growth conditions, mean N recovery from urea was about 67%, sometimes reaching 80%, of that from ammonium nitrate. Recovery of ammonium nitrate varied from 45 to 68% of applied N.

Soil Ph Correction Affecting N-Use Efficiency Of Urea By Brachiaria Brizantha Cv. Marandu Pastures, P. P. A. Oliveira, P. C. O. Trivelin, W. S. Oliveira, G. M. Teixeira, M. Corsi

IGC Proceedings (1977-2023)

Nitrogen fertilization is one of the largest investment when recovering and intensifying pasture management. Urea nitrogen use efficiency was studied in Brachiaria brizantha pasture under tropical conditions where liming was applied to the soil in two dates ("early" and "late" - March and August, respectively). Lime was broadcasted and urea was either broadcasted or subsurface-band applied. "Early" applied lime caused 16,4% increase in forage dry matter yield in the rainy season. Urea-N recovered in the shoots was higher when subsurface band applied independently from time of lime application.

Bacterial Biofilm Growth On Various Dental Stabilization Systems For Avulsed And Luxated Teeth, Mahmoud Mona, Clay Walker, Luciana M. Shaddox, Roberta Pileggi

Oral Health Practice Faculty Publications

With the increased incidence of traumatic injuries and the advanced understanding of the periodontal and alveolar healing process, teeth splinting has become a common practice for stabilizing traumatized teeth. Consequently, several splinting materials and techniques have been introduced in the past few years. Despite the detrimental role of bacterial biofilm on healing, the level of biofilm development on these material surfaces has not been well investigated. Bacterial biofilms are severely detrimental for periodontal healing of avulsed and luxated teeth. Thus, biofilm growth becomes a critical factor in selecting the material of choice for dental splints. In this study, we aim …

The Stress-Active Cell Division Protein Zape Alters Ftsz Filament Architecture To Facilitate Division In Escherichia Coli, Eric C. Dibiasio, Rebecca A. Dickinson, Catherine E. Trebino, Colby N. Ferreira, Josiah J. Morrison, Jodi L. Camberg

Cell and Molecular Biology Faculty Publications

During pathogenic infections, bacterial cells experience environmental stress conditions, including low oxygen and thermal stress. Bacterial cells proliferate during infection and divide by a mechanism characterized by the assembly of a large cytoskeletal structure at the division site called the Z-ring. The major protein constituting the Z-ring is FtsZ, a tubulin homolog and GTPase that utilizes the nucleotide to assemble into dynamic polymers. In Escherichia coli, many cell division proteins interact with FtsZ and modulate Z-ring assembly, while others direct cell wall insertion and peptidoglycan remodeling. Here, we show that ZapE, an ATPase that accumulates during late constriction, directly interacts …

A Reversal In Hair Cell Orientation Organizes Both The Auditory And Vestibular Organs., Basile Tarchini

Faculty Research 2021

Sensory hair cells detect mechanical stimuli with their hair bundle, an asymmetrical brush of actin-based membrane protrusions, or stereocilia. At the single cell level, stereocilia are organized in rows of graded heights that confer the hair bundle with intrinsic directional sensitivity. At the organ level, each hair cell is precisely oriented so that its intrinsic directional sensitivity matches the direction of mechanical stimuli reaching the sensory epithelium. Coordinated orientation among neighboring hair cells usually ensures the delivery of a coherent local group response. Accordingly, hair cell orientation is locally uniform in the auditory and vestibular cristae epithelia in birds and …

Metabolomics Of Healthy And Stony Coral Tissue Loss Disease Affected Montastraea Cavernosa Corals, Jessica M. Deutsch, Olakunle A. Jaiyesimi, Kelly A. Pitts, Jay Houk, Blake Ushijima, Brian K. Walker, Valerie J. Paul, Neha Garg

Marine & Environmental Sciences Faculty Articles

Stony coral tissue loss disease, first observed in Florida in 2014, has now spread along the entire Florida Reef Tract and on reefs in many Caribbean countries. The disease affects a variety of coral species with differential outcomes, and in many instances results in whole-colony mortality. We employed untargeted metabolomic profiling of Montastraea cavernosa corals affected by stony coral tissue loss disease to identify metabolic markers of disease. Herein, extracts from apparently healthy, diseased, and recovered Montastraea cavernosa collected at a reef site near Ft. Lauderdale, Florida were subjected to liquid-chromatography mass spectrometry-based metabolomics. Unsupervised principal component analysis reveals wide …

Dynamic Changes Of Brain Cilia Transcriptomes Across The Human Lifespan, Siwei Chen, Wedad Alhassen, Roudabeh Vakil Monfared, Benjamin Vachirakorntong, Surya M. Nauli, Pierre Baldi, Amal Alachkar

Pharmacy Faculty Articles and Research

Almost all brain cells contain primary cilia, antennae-like microtubule sensory organelles, on their surface, which play critical roles in brain functions. During neurodevelopmental stages, cilia are essential for brain formation and maturation. In the adult brain, cilia play vital roles as signaling hubs that receive and transduce various signals and regulate cell-to-cell communications. These distinct roles suggest that cilia functions, and probably structures, change throughout the human lifespan. To further understand the age-dependent changes in cilia roles, we identified and analyzed age-dependent patterns of expression of cilia’s structural and functional components across the human lifespan. We acquired cilia transcriptomic data …

Dartmouth Scholarship

Advances in experimental capabilities in the glycosciences offer expanding opportunities for discovery in the broad areas of immunology and microbiology. These two disciplines overlap when microbial infection stimulates host immune responses and glycan structures are central in the processes that occur during all such encounters. Microbial glycans mediate host-pathogen interactions by acting as surface receptors or ligands, functioning as virulence factors, impeding host immune responses, or playing other roles in the struggle between host and microbe. In the context of the host, glycosylation drives cell–cell interactions that initiate and regulate the host response and modulates the effects of antibodies and …

"It Was A Season..." Postpartum Depression In American Indian/Alaska Native Women, Jennifer Leigh Heck

Dissertations

Postpartum depression (PPD) is linked to diminished maternal, pediatric, and family health outcomes and is designated as the most common childbirth complication. PPD is found in most populations, and touts international status as a major public health concern. Clinicians define PPD as an episode of major depressive disorder with a "peripartum onset" that occurs within the first year after delivery. Studies suggest that American Indian/Alaska Native (AI/AN) women suffer higher PPD prevalence (14% to 29%) than other United States' women, revealing a racial/ethnic disparity. Health disparities research is a national public health priority and substantiates the need to explore PPD …
