The first included six indicators (child wasting, child overweight, non-communicable disease [NCD] mortality, universal health coverage service coverage index, health worker density, and education attainment), covering 195 countries between 1990-2017. The second included the aforementioned indicators plus an urban …

Optimization Of Host Cell-Compatible, Antimicrobial Peptides Effective Against Biofilms And Clinical Isolates Of Drug-Resistant Bacteria, Jenisha Ghimire, Robert J. Hart, Anabel Soldano, Charles H. Chen, Shantanu Guha, Joseph P. Hoffmann, Kalen M. Hall, Leisheng Sun, Benjamin J. Nelson, Timothy K. Lu, Jay K. Kolls, Mario Rivera, Lisa A. Morici, William C. Wimley

Faculty Publications

Here, we describe the continued synthetic molecular evolution of a lineage of host-compatible antimicrobial peptides (AMP) intended for the treatment of wounds infected with drug-resistant, biofilm-forming bacteria. The peptides tested are variants of an evolved AMP called d-amino acid CONsensus with Glycine Absent (d-CONGA), which has excellent antimicrobial activities in vitro and in vivo. In this newest generation of rational d-CONGA variants, we tested multiple sequence-structure-function hypotheses that had not been tested in previous generations. Many of the peptide variants have lower antibacterial activity against Gram-positive or Gram-negative pathogens, especially variants that have altered hydrophobicity, secondary structure potential, or spatial …

Ion Selective And Water Resistant Cellulose Nanofiber/Mxene Membrane Enabled Cycling Zn Anode At High Currents, Wangwang Xu, Xiaobin Liao, Weina Xu, Kangning Zhao, Guang Yao, Qinglin Wu

Faculty Publications

Aqueous rechargeable zinc ion batteries (ZIBs) are regarded as a promising candidates for next-generation energy storage devices but strongly hindered by the limited utilization of the zinc metal anode (below 5%) due to the active water/anion corrosion. Herein, an ion selective and water-resistant cellulose nanofiber (CNF)/MXene composite membrane has been developed through molecular sieving to restrict active water and anions from the electrode/electrolyte interface through dehydration of zinc ions, avoiding the water/anion-induced corrosion/decomposition. In this way, the CNF/MXene@Zn anode exhibits significantly enhanced coulombic efficiency (99.5 % at 10 mA cm-2) and low voltage hysteresis. Moreover, coated with CNF/MXene composite membrane, …

New Perspectives On Foot Segment Forces And Joint Kinetics - Integrating Plantar Shear Stresses And Pressures With Multi-Segment Foot Modeling, Dustin A. Bruening, Spencer R. Petersen, Sarah T. Ridge

Faculty Publications

The role of the foot in gait is not well understood, in part due to challenges in capturing and utilizing segmental ground reaction forces. The purposes of this study were to 1) develop methodology to integrate plantar pressure/shear stresses with a multi-segment foot model, and 2) generate and display key normative data from this combined system. Twenty-six young healthy adults walked barefoot (1.3 m/s) across a pressure/shear sensor with markers matching a published 4-segment kinetic foot model. A novel anatomical/geometric masking method was developed that successfully separated regions aligned with model segmentation. This template-based method can be automated and customized …

Does Mitochondrial Replacement Therapy Violate Laws Against Human Cloning?, Kerry L. Macintosh

Faculty Publications

All human beings have mitochondria within their cells that produce energy.1 Most of us inherit healthy mitochondria through the eggs of our mothers,2 but some of us are not so lucky. Mutations in mitochondrial DNA (mtDNA) can cause these tiny organelles to function improperly and disrupt tissues that require a lot of energy, like the brain, kidney, liver, heart, muscle, and central nervous system.3 For example, a specific mtDNA mutation induces Leigh syndrome, a condition in which seizures and respiratory failure lead to decline in mental and motor skills, disabil- ity, and death.4 Mitochondrial replacement therapy (MRT) offers a solution …

A Quieter Ocean: Experimentally Derived Differences In Attentive Responses Of Tursiops Truncatus To Anthropogenic Noise Playbacks Before And During The Covid-19-Related Anthropause, Paige E. Stevens, Veda Allen, Jason N. Bruck

Faculty Publications

The effects of anthropogenic noise continue to threaten marine fauna, yet the impacts of human-produced sound on the broad aspects of cognition in marine mammals remain relatively understudied. The shutdown of non-essential activities due to the COVID-19-related anthropause created an opportunity to determine if reducing levels of oceanic anthropogenic noise on cetaceans affected processes of sensitization and habituation for common human-made sounds in an experimental setting. Dolphins at Dolphin Quest Bermuda were presented with three noises related to human activities (cruise ship, personal watercraft, and Navy low-frequency active sonar) both in 2018 and again during the anthropause in 2021 via …

Horizontally Transferred Genes As Rna Interference Targets For Aphid And Whitefly Control, Honglin Feng, Wenbo Chen, Sonia Hussain, Sara Shakir, Vered Tzin, Femi Adegbayi, Todd Ugine, Zhangjun Fei, Georg Jander

Faculty Publications

RNA interference (RNAi)-based technologies are starting to be commercialized as a new approach for agricultural pest control. Horizontally transferred genes (HTGs), which have been transferred into insect genomes from viruses, bacteria, fungi or plants, are attractive targets for RNAi-mediated pest control. HTGs are often unique to a specific insect family or even genus, making it unlikely that RNAi constructs targeting such genes will have negative effects on ladybugs, lacewings and other beneficial predatory insect species. In this study, we sequenced the genome of a red, tobacco-adapted isolate of Myzus persicae (green peach aphid) and bioinformatically identified 30 HTGs. We then …

Faculty Publications

The human skin, an important sensory organ, responds sensitively to external stimuli under various harsh conditions. However, the simultaneous achievement of mechanical/thermal sensitivity and extreme environmental tolerance remains an enormous challenge for skin-like hydrogel-based sensors. In this study, a novel skin-inspired hydrogel–elastomer hybrid with a sandwich structure and strong interfacial bonding for mechanical–thermal multimode sensing applications is developed. An inner-layered ionic hydrogel with a semi-interpenetrating network is prepared using sodium carboxymethyl cellulose (CMC) as a nanofiller, lithium chloride (LiCl) as an ionic transport conductor, and polyacrylamide (PAM) as a polymer matrix. The outer-layered polydimethylsiloxane (PDMS) elastomers fully encapsulating the hydrogel …

Regional Variation In Feeding Patterns Of Sheepshead (Archosargus Probatocephalus) In The Northwest Gulf Of Mexico, Elsa M. Gutierrez, Jeffrey D. Plumlee, Derek G. Bolser, Brad E. Erisman, R. J.David Wells

Faculty Publications

Feeding patterns of sheepshead, Archosargus probatocephalus, in the northwest Gulf of Mexico were examined from samples collected at two locations in Texas, USA; Galveston and Port Aransas. A total of 53 sheepshead stomachs (Galveston, n = 35; Port Aransas, n = 18) had their contents analyzed along with tissue samples from the muscle and liver for a stable isotope analysis (δ13C, δ15N, and δ34S) because they provide a contrast between short-term (liver) and long-term (muscle) measurements. Multiple species of amphipods made up the majority of the prey items in sheepshead from Galveston (%IRI = 61.79), whereas barnacles were the primary …

Low Species Turnover Of Upland Amazonian Birds In The Absence Of Physical Barriers, Cameron L. Rutt, W. Justin Cooper, Christian B. Andretti, Thiago V.V. Costa, Philip C. Stouffer, Claudeir F. Vargas, David A. Luther, Mario Cohn-Haft

Faculty Publications

Aim: One of the oldest and most powerful ways for ecologists to explain distinct biological communities is to invoke underlying environmental differences. But in hyper-diverse systems, which often display high species richness and low species abundance, these sorts of community comparisons are especially challenging. The classic view for Amazonian birds posits that riverine barriers and habitat specialization determine local and regional community composition. We test the tacit, complementary assumption that similar bird communities should therefore permeate uniform habitat between major rivers, regardless of distance. Location: Upland (terra firme) rainforests of central Amazonia. Methods: We conducted intensive whole-community surveys of birds …

Obesity is caused by a prolonged positive energy balance1,2. Whether reduced energy expenditure stemming from reduced activity levels contributes is debated3,4. Here we show that in both sexes, total energy expenditure (TEE) adjusted for body composition and age declined since the late 1980s, while adjusted activity energy expenditure increased over time. We use the International Atomic Energy Agency Doubly Labelled Water database on energy expenditure of adults in the United States and Europe (n = 4,799) to explore patterns in total (TEE: n = 4,799), basal (BEE: n = 1,432) and physical activity energy expenditure (n = 1,432) over time. …

Stable Isotope Tracing Reveals An Altered Fate Of Glucose In N-Acetyltransferase 1 Knockout Breast Cancer Cells, James T.F. Wise, Xinmin Yin, Xipeng Ma, Xiang Zhang, David W. Hein

Faculty Publications

Breast cancer is one of the leading causes of cancer death. Recent studies found that arylamine N-acetyltransferase 1 (NAT1) is frequently upregulated in breast cancer, further suggesting NAT1 could be a potential therapeutic target for breast cancer. Previous publications have established that NAT1 knockout (KO) in breast cancer cell lines leads to growth reduction both in vitro and in vivo and metabolic changes. These reports suggest that NAT1 contributes to the energy metabolism of breast cancer cells. Proteomic analysis and non-targeted metabolomics suggested that NAT1 KO may change the fate of glucose as it relates to the TCA/KREB cycle of …

Ecophysiology And Genomics Of The Brackish Water Adapted Sar11 Subclade Iiia, V. Celeste Lanclos, Anna N. Rasmussen, Conner Y. Kojima, Chuankai Cheng, Michael W. Henson, Brant C. Faircloth, Christopher A. Francis, J. Cameron Thrash

Faculty Publications

The Order Pelagibacterales (SAR11) is the most abundant group of heterotrophic bacterioplankton in global oceans and comprises multiple subclades with unique spatiotemporal distributions. Subclade IIIa is the primary SAR11 group in brackish waters and shares a common ancestor with the dominant freshwater IIIb (LD12) subclade. Despite its dominance in brackish environments, subclade IIIa lacks systematic genomic or ecological studies. Here, we combine closed genomes from new IIIa isolates, new IIIa MAGS from San Francisco Bay (SFB), and 460 highly complete publicly available SAR11 genomes for the most comprehensive pangenomic study of subclade IIIa to date. Subclade IIIa represents a taxonomic …

North Flinders Reef (Coral Sea, Australia) Porites Sp. Corals As A Candidate Global Boundary Stratotype Section And Point For The Anthropocene Series, Jens Zinke, Neal E. Cantin, Kristine L. Delong, Kylie Palmer, Arnoud Boom, Irka Hajdas, Nicolas Duprey, Alfredo Martínez-García, Neil L. Rose, Sarah L. Roberts, Handong Yang, Lucy R. Roberts, Andrew B. Cundy, Pawel Gaca, James Andy Milton, Grace Frank, Adam Cox, Sue Sampson, Genevieve Tyrrell, Molly Agg, Simon D. Turner

Faculty Publications

Corals are unique in the suite of proposed Anthropocene Global Boundary Stratotype Section and Point (GSSP) archives, as living organisms that produce aragonite exoskeletons preserved in the geological record that contain highly accurate and precise (<±1 year) internal chronologies. The GSSP candidate site North Flinders Reef in the Coral Sea (Australia) is an offshore oceanic reef, and therefore less vulnerable to local human influences than those closer to the coast. Here, we present geochemical records from two Porites sp. corals sampled at an annual to pluri-annual (i.e. 3–5 years) resolution that shows clear global and regional human impacts. Atmospheric nuclear bomb testing by-products (14C,239+240Pu) show a clear increase in the Flinders Reef corals coincident with well-dated nuclear testing operations. By contrast, the radionuclides 241Am and 137Cs are present at low or undetectable levels, as are spheroidal carbonaceous fly-ash particles. Coral δ13C shows centennial variability likely influenced by growth effects in the 18th century and with a progression to lower values starting in 1880 CE and accelerating post-1970 CE. The latter may be related to the Suess effect resulting from 13C-depleted fossil fuel burning. Coral δ15N decreased between 1710 and 1954 CE with a reversal post-1954 CE. Coral temperature proxies indicate prominent centennial variability with equally warm conditions in the 18th and end of 20th century. However, the exact mechanisms responsible for the mid-20th century changes in these parameters need to be scrutinised in further detail. Plain Language summary: This work proposes a candidate natural archive for the official marker of the Anthropocene that geologists will use to mark this important interval in time. Our candidate is a live coral from North Flinders Reef in the Coral Sea (Australia), located 150 km east of the Great Barrier Reef, a location that is remote from direct local human influences. Corals are a unique archive of tropical ocean change because they incorporate the geochemical signature from seawater into their limestone skeleton during their long life-spans. Here we investigated a number of geochemical markers in yearly growth layers of the corals to define several markers for the Anthropocene based on changes in temperature, water chemistry, chemicals from pollution and fertilisers, radioactive products from nuclear bomb testing, and by-products from burning fossil fuels. We have detected clear human influences in several of these markers.

Projections of Antarctica's contribution to future sea level rise are associated with significant uncertainty, in part because the observational record is too short to capture long-term processes necessary to estimate ice mass changes over societally relevant timescales. Records of grounding line retreat from the geologic past offer an opportunity to extend our observations of these processes beyond the modern record and to gain a more comprehensive understanding of ice-sheet change. Here, we present constraints on the timing and inland extent of deglacial grounding line retreat in the southern Ross Sea, Antarctica, obtained via direct sampling of a subglacial lake located …

Gas Hydrates Reserve Characterization Using Thermo-Hydro-Mechanical Numerical Simulation: A Case Study Of Green Canyon 955, Gulf Of Mexico, Sulav Dhakal, Ipsita Gupta

Faculty Publications

The Gulf of Mexico is a widely explored and producing region for offshore oil and gas resources, with significant submarine methane hydrates. Estimates of hydrate saturation and distribution rely on drilling expeditions and seismic surveys that tend to provide either large-scale estimates or highly localized well data. In this study, hydrate reserve characterization is done using numerical simulation at Green Canyon block 955 (GC955). In addition, coupled thermo-hydro-mechanical (THM) simulation results show that hydrate saturation and geobody distribution are determined by the thermodynamic conditions as well as reservoir structures, stratigraphic differences, and permeability differences. Hydrate formation due to upflow of …
