Chimica et Natura Acta

α-Hydroxyisovaleric acid (Ac-Hiv) and α-acetyloxyisovaleric acid (Ac-Hiv) have been successfully synthesized through a diazotisation of amino acid using sodium nitrite with the catalyst of sulfuric acid and acetic acid, respectively. In the synthesis of Hiv, Zubia et al. (2005) mentioned that 3 equivalents of sodium nitrite for the reaction gave the hydroxy acid with a good yield. However, Cohen-Arazi et al. (2008) described that 6 equivalents of sodium nitrite resulted the highest yield. In present study, a variation of equivalents of sodium nitrite (3, 4, 5, 6 eq.) were trialed for the same method of synthesis. Through several experiments, we …

Highly Efficient 5' Capping Of Mitochondrial Rna With Nad+ And Nadh By Yeast And Human Mitochondrial Rna Polymerase, Jeremy G Bird, Urmimala Basu, David Kuster, Aparna Ramachandran, Ewa Grudzien-Nogalska, Atif Towheed, Douglas C. Wallace, Megerditch Kiledjian, Dmitry Temiakov, Smita S. Patel, Richard H. Ebright, Bryce E. Nickels

Department of Biochemistry and Molecular Biology Faculty Papers

Bacterial and eukaryotic nuclear RNA polymerases (RNAPs) cap RNA with the oxidized and reduced forms of the metabolic effector nicotinamide adenine dinucleotide, NAD+ and NADH, using NAD+ and NADH as non-canonical initiating nucleotides for transcription initiation. Here, we show that mitochondrial RNAPs (mtRNAPs) cap RNA with NAD+ and NADH, and do so more efficiently than nuclear RNAPs. Direct quantitation of NAD+- and NADH-capped RNA demonstrates remarkably high levels of capping in vivo: up to ~60% NAD+ and NADH capping of yeast mitochondrial transcripts, and up to ~15% NAD+ capping of human mitochondrial transcripts. The capping efficiency is determined by promoter …

Using A Robot Peer To Encourage The Production Of Spatial Concepts In A Second Language, Cd Wallbridge, Den Berghe R Van, Hernandez D Garcia, J Kanero, S Lemaignan, C Edmunds, T Belpaeme

School of Engineering, Computing and Mathematics

We conducted a study with 25 children to investigate the efectiveness of a robot measuring and encouraging production of spatial concepts in a second language compared to a human experimenter. Productive vocabulary is often not measured in second language learning, due to the diiculty of both learning and assessing productive learning gains. We hypothesized that a robot peer may help assessing productive vocabulary. Previous studies on foreign language learning have found that robots can help to reduce language anxiety, leading to improved results. In our study we found that a robot is able to reach a similar performance to the …

Weak Iron Oxidation By Sulfobacillus Thermosulfidooxidans Maintains A Favorable Redox Potential For Chalcopyrite Bioleaching, S Christel, M Herold, S Bellenberg, A Buetti-Dinh, Et Al

School of Biomedical Sciences

Bioleaching is an emerging technology, describing the microbially assisted dissolution of sulfidic ores that provides a more environmentally friendly alternative to many traditional metal extraction methods, such as roasting or smelting. Industrial interest is steadily increasing and today, circa 15–20% of the world’s copper production can be traced back to this method. However, bioleaching of the world’s most abundant copper mineral chalcopyrite suffers from low dissolution rates, often attributed to passivating layers, which need to be overcome to use this technology to its full potential. To prevent these passivating layers from forming, leaching needs to occur at a low oxidation/reduction …

Assessment Of Topsoil Salvage And Seed Augmentation In The Restoration Of Coastal Sage Scrub On Santa Catalina Island, California, Peter J. Dixon

Western North American Naturalist

The Catalina Island Conservancy manages over 22,000 acres of coastal (California) sage scrub (CSS) habitat off the coast of Southern California, including much of the infrastructure, roads, and recreation associated with habitat disturbance. Restoration trials were initiated to establish best management practices for roadside and disturbed site revegetation under local site conditions. Site treatments compared excavated native subsoil and surface soil (±20 cm) reapplication practices with and without seed augmentation. Evaluation of native and nonnative germinants indicated that salvaged surface soil alone may not be sufficient to restore native cover. Seeding improved native cover and reduced establishment of nonnative species …

Corporate Political Strategies And Return Predictability, Chansog Kim, Incheol Kim, Christos Pantzalis, Jung Chul Park

School of Economics and Finance Faculty Publications

We assess whether observable corporate political strategies can serve as channels of value relevant political information flow into stock prices and form the basis for profitable return predictability strategies. We document that returns of politically connected firms’ stocks lead those of their non-connected peers, suggesting that information shocks associated with new policies and other political developments become evident first in the stock prices of firms that pursue political strategies and then, with delay, in those of similar non-connected firms.

Strategic Logistics Outsourcing In Humanitarian Supply Chain: A Fuzzy Ahp Approach, S Roh, H-M Jang

The Wind: An Unruly Living, Jeremy Bendik-Keymer

Faculty Scholarship

A process begun in Pisa, Italy in April of 2016 during a workshop on political theory in the Anthropocene, The Wind ~ An Unruly Living is a philosophical exercise (askêsis, translated, following Ignatius of Loyola, as “spiritual exercise”). In his exercise, Bendik-Keymer throws to the void: the ideology of self-ownership from a society of possession. By using the Stoic kanôn, the rule of living by phûsis, he follows an element. Unhappily for the Stoic and happily for us, the wind is unruly. A swerve of currents through a social fabric, it’s full of holes, all holely. Stretch …

Usefulness Of Baseline Statin Therapy In Non-Obstructive Coronary Artery Disease By Coronary Computed Tomographic Angiography: From The Confirm (Coronary Ct Angiography Evaluation For Clinical Outcomes: An International Multicenter) Study, Ricardo Cury

All Publications

BACKGROUND:

The extent to which the presence and extent of subclinical atherosclerosis by coronary computed tomography angiography influences a potential mortality benefit of statin is unknown. We evaluated the relationship between statin therapy, mortality, and subclinical atherosclerosis.

METHODS:

In the CONFIRM study, patients with normal or non-obstructive plaque (<50% diameter stenosis) for whom data on baseline statin use was available were included. Coronary artery calcium (CAC) was quantified using the Agatston score. The extent of non-obstructive coronary atherosclerosis was quantified using the segment involvement score (SIS). 8,016 patients were followed for a median of 2.5 years with analysis of all-cause mortality and major adverse cardiac events (MACE) including all-cause mortality, myocardial infarction, unstable angina, target vessel revascularization, and coronary artery disease-related hospitalization.

RESULTS:

1.2% of patients experienced all-cause mortality. Patients not on baseline statin therapy had a stepwise increased risk of all-cause mortality by CAC (relative to CAC = 0; CAC 1-99: hazard ratio [HR] 1.65, CAC 100-299: HR 2.19, and CAC≥300: HR 2.98) or SIS (relative to SIS = 0; SIS 1: …

Snap-Jaw Morphology Is Specialized For High-Speed Power Amplification In The Dracula Ant, Mystrium Camillae, Fredrick J. Larabee, Adrian A. Smith, Andrew V. Suarez

Faculty Research, Scholarly, and Creative Activity

What is the limit of animal speed and what mechanisms produce the fastest movements? More than natural history trivia, the answer provides key insight into the form-function relationship of musculoskeletal movement and can determine the outcome of predator-prey interactions. The fastest known animal movements belong to arthropods, including trap-jaw ants, mantis shrimp and froghoppers, that have incorporated latches and springs into their appendage systems to overcome the limits of muscle power. In contrast to these examples of power amplification, where separate structures act as latch and spring to accelerate an appendage, some animals use a 'snap-jaw' mechanism that incorporates the …

Changing Land-Use From Pinus Elliottii To Eucalyptus Bentamii In Southwest Louisiana Affects Understory Vegetation Richness, Diversity, And Functional Diversity Patterns, Andrea De Stefano

LSU Doctoral Dissertations

In the Western Gulf region of the United States cold-tolerant eucalyptus have been explored as pulpwood feedstock. However, non-native plantations may alter understory species diversity, modifying environmental conditions and soil characteristics. Few studies have compared eucalyptus plantations with other ecosystems to understand the impacts of converting these land uses on understory vegetation in the United States. Three plantations were selected: (1) slash pine (Pinus elliottii) established in 2008, (2) slash pine established in 2013, and (3) and Camden white gum (Eucalyptus benthamii) established in 2013. The objectives of this study were to: (1) investigate potential changes …

Pairwise Clusters Optimization And Cluster Most Significant Feature Methods For Anomaly-Based Network Intrusion Detection System (Poc2msf), Gervais Hatungimana

Malaysian Journal of Computing (MJoC)

Anomaly-based Intrusion Detection System (IDS) uses known baseline to detect patterns which have deviated from normal behavior. If the baseline is faulty, the IDS performance degrades. Most of researches in IDS which use k-centroids-based clustering methods like K-means, K-medoids, Fuzzy, Hierarchical and agglomerative algorithms to baseline network traffic suffer from high false positive rate compared to signature-based IDS, simply because the nature of these algorithms risk to force some network traffic into wrong profiles depending on K number of clusters needed. In this paper, we propose an alternative method which instead of defining K number of clusters, defines t distance …
