Cardeza Foundation for Hematologic Research

Blood transfusion and iron chelation currently represent a supportive therapy to manage anemia, vasculopathy and vaso-occlusion crises in Sickle-Cell-Disease. Here we describe the first 5-year long-term randomized clinical trial comparing Deferiprone versus Deferoxamine in patients with Sickle-Cell-Disease. The results of this study show that Deferiprone has the same effectiveness as Deferoxamine in decreasing body iron burden, measured as repeated measurements of serum ferritin concentrations on the same patient over 5-years and analyzed according to the linear mixed-effects model (LMM) (p=0.822). Both chelators are able to decrease, significantly, serum ferritin concentrations, during 5-years, without any effect on safety (p=0.005). Moreover, although …

Primary Stroke In A Woman With Sickle Cell Anemia Responsive To Hydroxyurea Therapy., Samir K. Ballas, Ubaldo E. Martinez-Outshoorn, Michael P. Savage

Cardeza Foundation for Hematologic Research

The most common cause of stroke in children with sickle cell anemia is infarction due to ischemia. In adults, however, stroke is most commonly hemorrhagic in nature. Other causes of stroke in patients with sickle cell disease are very rare. In this short communication, we describe a woman with sickle cell anemia responsive to hydroxyurea (HU) therapy who had primary stroke due to paradoxical embolization caused by a large atrial septal defect. Successful management of the stroke included surgical closure of the defect with trans-esophageal echocardiographic guidance. To the best of our knowledge, this is the first patient with sickle …

Journal of International Technology and Information Management

With the massive increase in the data being collected as a result of ubiquitous information gathering devices, and the increased need for doing data mining and analyses, there is a need for scaling up and improving the performance of traditional data mining and learning algorithms. Two related fields of distributed data mining and ensemble learning aim to address this scaling issue. Distributed data mining looks at how data that is distributed can be effectively mined without having to collect the data at one central location. Ensemble learning techniques aim to create a meta-classifier by combining several classifiers created on the …

Entropy Based Feature Selection For Multi-Relational Naïve Bayesian Classifier, Vimalkumar B. Vaghela, Kalpesh H. Vandra, Nilesh K. Modi Jan 2014

Entropy Based Feature Selection For Multi-Relational Naïve Bayesian Classifier, Vimalkumar B. Vaghela, Kalpesh H. Vandra, Nilesh K. Modi

Journal of International Technology and Information Management

Current industries data’s are stored in relation structures. In usual approach to mine these data, we often use to join several relations to form a single relation using foreign key links, which is known as flatten. Flatten may cause troubles such as time consuming, data redundancy and statistical skew on data. Hence, the critical issues arise that how to mine data directly on numerous relations. The solution of the given issue is the approach called multi-relational data mining (MRDM). Other issues are irrelevant or redundant attributes in a relation may not make contribution to classification accuracy. Thus, feature selection is …

A Web-Based Knowledge Management Tool Utilizing Concept Maps For On-Line Student Advising, Jay M. Lightfoot Jan 2014

A Web-Based Knowledge Management Tool Utilizing Concept Maps For On-Line Student Advising, Jay M. Lightfoot

Journal of International Technology and Information Management

Increasingly complex program offerings by universities combined with on-line educational opportunities have created a situation where students must deal with an extremely complicated array of curriculum decisions. At the same time, many universities are moving away from the traditional one-on-one advising model toward one that relies heavily on web-based resources. The result of this is that students are often forced to self-advise using complicated and often poorly structured websites. This paper describes a knowledge management tool to mitigate this problem by creating an intuitive, web-based interface to help students navigate directly to the Internet advising materials that are most applicable.

A Conflict Resolution Tool For Project Managers: Evaporating Cloud, Mahesh C. Gupta, Sharon A. Kerrick Jan 2014

A Conflict Resolution Tool For Project Managers: Evaporating Cloud, Mahesh C. Gupta, Sharon A. Kerrick

Journal of International Technology and Information Management

Today’s ever changing business environment requires managers to interact globally with people across functional areas with conflicting points of view. A preliminary literature review suggests that a generic tool to understand and resolve conflicts is desirable. This paper demonstrates how a theory of constraints-based logical tool, an evaporating cloud, can enable IT managers to better understand conflicts underlying most problems. Using a commonly encountered conflict as an example, we show how this tool verbalizes a problem through the logic of cause and effect, surfaces the assumptions causing the conflicting actions and decisions, and presents injections – potential solutions – that …

When Google Meets Xiaomi: Comparative Case Study In Western And Eastern Corporate Management, Yu-Feng Lin Lee Jan 2014

When Google Meets Xiaomi: Comparative Case Study In Western And Eastern Corporate Management, Yu-Feng Lin Lee

Journal of International Technology and Information Management

Google Inc. of the West and Xiaomi Inc. of the East are recognized as ‘flat organizations’. They exercise ‘flat management’ in their corporate culture, wherein mid-level management is abridged, leaving the corporate structure less-bureaucratic, top-down-and-less-hierarchical, and more laissez-faire. Using the Confucian criteria of Wu Yu, namely morality (or, virtue), intellectual (or, wisdom), physical ability (or, sportsmanship), groupism (or, cooperation), and aesthetics (or, elegance), this paper assesses managerial philosophy and corporate practice of Google and Xiaomi. It is found that under flat management, although each company nevertheless reveals its corporate idiosyncrasy, they achieve business success and sustainability through adopting small-team orientation, …

Electronic Health Records: Challenges And Opportunities, Jaymeen R. Shah, Mirza B. Murtaza, Emmanuel Opara

Journal of International Technology and Information Management

During the last three decades, healthcare expenditure in the U.S. has substantially increased. If this pace of increase is not controlled, it will lead to disastrous results for the healthcare system. An effective use of health information technology would not only improve the quality of healthcare but help reduce healthcare costs considerably. However, risks of privacy and security of patient electronic health records are great. It is recommended that healthcare organizations use IT management best practices, follow proper risk assessment and management guidelines, and keep up with latest technological advances to ensure the privacy and security of patient data.

Developmental Changes In The Organization Of Functional Connections Between The Basal Ganglia And Cerebral Cortex, Deanna J. Greene, Timothy O. Laumann, Joseph W. Dubis, S. Katie Ihnen, Maital Neta, Jonathan D. Power, John R. Pruett Jr., Kevin J. Black, Bradley L. Schlaggar Jan 2014

Developmental Changes In The Organization Of Functional Connections Between The Basal Ganglia And Cerebral Cortex, Deanna J. Greene, Timothy O. Laumann, Joseph W. Dubis, S. Katie Ihnen, Maital Neta, Jonathan D. Power, John R. Pruett Jr., Kevin J. Black, Bradley L. Schlaggar

Department of Psychology: Faculty Publications

The basal ganglia (BG) comprise a set of subcortical nuclei with sensorimotor, cognitive, and limbic subdivisions, indicative of functional organization. BG dysfunction in several developmental disorders suggests the importance of the healthy maturation of these structures. However, few studies have investigated the development of BG functional organization. Using resting-state functional connectivity MRI (rs-fcMRI), we compared human child and adult functional connectivity of the BG with rs-fcMRI-defined cortical systems. Because children move more than adults, customized preprocessing, including volume censoring, was used to minimize motion-induced rsfcMRI artifact. Our results demonstrated functional organization in the adult BG consistent with subdivisions previously identified …

Phosphatase-Inert Glucosamine 6‑Phosphate Mimics Serve As Actuators Of The Glms Riboswitch, Xiang Fei, Thomas Holmes, Julianna Diddle, Lauren Hintz, Dan Delaney, Alex Stock, Danielle Renner, Molly Mcdevitt, David B. Berkowitz, Juliane K. Soukup Jan 2014

Phosphatase-Inert Glucosamine 6‑Phosphate Mimics Serve As Actuators Of The Glms Riboswitch, Xiang Fei, Thomas Holmes, Julianna Diddle, Lauren Hintz, Dan Delaney, Alex Stock, Danielle Renner, Molly Mcdevitt, David B. Berkowitz, Juliane K. Soukup

David Berkowitz Publications

The glmS riboswitch is unique among generegulating riboswitches and catalytic RNAs. This is because its own metabolite, glucosamine-6-phosphate (GlcN6P), binds to the riboswitch and catalytically participates in the RNA selfcleavage reaction, thereby providing a novel negative feedback mechanism. Given that a number of pathogens harbor the glmS riboswitch, artificial actuators of this potential RNA target are of great interest. Structural/kinetic studies point to the 2- amino and 6-phosphate ester functionalities in GlcN6P as being crucial for this actuation. As a first step toward developing artificial actuators, we have synthesized a series of nine GlcN6P analogs bearing phosphatase-inert surrogates in place …

Metallurgical And Corrosion Assessment Of Submerged Tanker S.S. Montebello, Dana Medlin, James D. Carr, Donald L. Johnson, David L. Conlin

Department of Chemistry: Faculty Publications

The Union Oil Tanker S.S. Montebello was torpedoed and sunk six miles (9.7 km) off the coast of Cambria, California by a Japanese submarine on December 23, 1941, two weeks after the attack on Pearl Harbor. With close proximity to the National Monterey Bay Marine Sanctuary, concern about possible crude oil contamination led to the most recent expedition to the site in October 2011. Assessment of the shell plate found that the average corrosion rate was very low and the structure will remain stable for many decades.

Β-Keto And Β-Hydroxyphosphonate Analogs Of Biotin-5’-Amp Are Inhibitors Of Holocarboxylase Synthetase, Wantanee Sittiwong, Elizabeth Cordonier, Janos Zempleni, Patrick Dussault

Patrick Dussault Publications

Holocarboxylase synthetase (HLCS) catalyzes the covalent attachment of biotin to cytoplasmic and mitochondrial carboxylases, nuclear histones, and over a hundred human proteins. Nonhydrolyzable ketophosphonate (β-ketoP) and hydroxyphosphonate (β-hydroxyP) analogs of biotin-5′-AMP inhibit holocarboxylase synthetase (HLCS) with IC50 values of 39.7 μM and 203.7 μM. By comparison, an IC50 value of 7 μM was observed with the previously reported biotinol-5'-AMP. The Ki values, 3.4 μM and 17.3 μM, respectively, are consistent with the IC50 results, and close to the Ki obtained for biotinol-5'-AMP (7 μM). The β-ketoP and β-hydroxyP molecules are competitive inhibitors of HLCS while biotinol-5'-AMP …

The Temperature Independence Of Interaction Strength In A Sit-And-Wait Predator, Rachel A. Novich, Emma K. Erickson, Ryan M. Kalinoski, John Delong Jan 2014

The Temperature Independence Of Interaction Strength In A Sit-And-Wait Predator, Rachel A. Novich, Emma K. Erickson, Ryan M. Kalinoski, John Delong

School of Biological Sciences: Faculty Publications

The strength of interactions between consumers and their resources has important implications for the overall structure and function of food webs. These interactions can change with warming, depending on the foraging mode of the predator. Theory predicts that warming increases foraging velocity in ectotherms, but in a sit-and-wait predator that has zero velocity when foraging, the interaction strength should be temperature independent. Using the protist Urocentrum turbo and the sit-and- wait copepod Orthocyclops modestus, we tested this prediction by measuring dynamic interaction strengths (effect of a predator on prey population growth rate) and by estimating the parameters of a …

School of Biological Sciences: Faculty Publications

In air-breathing vertebrates, the physiologically optimal blood-O2 affinity is jointly determined by the prevailing partial pressure of atmospheric O2, the efficacy of pulmonary O2 transfer, and internal metabolic demands. Consequently, genetic variation in the oxygenation properties of hemoglobin (Hb) may be subject to spatially varying selection in species with broad elevational distributions. Here we report the results of a combined functional and evolutionary analysis of Hb polymorphism in the rufouscollared sparrow (Zonotrichia capensis), a species that is continuously distributed across a steep elevational gradient on the Pacific slope of the Peruvian Andes. We integrated …

Toruno, Christian G. Elowsky, Chi Zhang, Jens Steinbrenner, Jim Beynon, James R. Alfano Jan 2014

The Pseudomonas Syringae Type Iii Effector Hopd1 Suppresses Effector-Triggered Immunity, Localizes To The Endoplasmic Reticulum, And Targets The Arabidopsis Transcription Factor Ntl9, Anna Block, Tania Y. Toruno, Christian G. Elowsky, Chi Zhang, Jens Steinbrenner, Jim Beynon, James R. Alfano

Nebraska Center for Biotechnology: Faculty and Staff Publications

Pseudomonas syringae type III effectors are known to suppress plant immunity to promote bacterial virulence. However, the activities and targets of these effectors are not well understood. We used genetic, molecular, and cell biology methods to characterize the activities, localization, and target of the HopD1 type III effector in Arabidopsis. HopD1 contributes to P. syringae virulence in Arabidopsis and reduces effector-triggered immunity (ETI) responses but not pathogen-associated molecular pattern-triggered immunity (PTI) responses. Plants expressing HopD1 supported increased growth of ETI-inducing P. syringae strains compared with wild-type Arabidopsis. We show that HopD1 interacts with the membrane-tethered Arabidopsis transcription factor NTL9 and …

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Swiss needle cast (SNC) is a fungal disease of Douglas-fir (Pseudotsuga menziesii) that has recently become prevalent in coastal areas of the Pacific Northwest. We used growth measurements and stable isotopes of carbon and oxygen in tree-rings of Douglas-fir and a non-susceptible reference species (western hemlock, Tsuga heterophylla) to evaluate their use as proxies for variation in past SNC infection, particularly in relation to potential explanatory climate factors. We sampled trees from an Oregon site where a fungicide trial took place from 1996 to 2000, which enabled the comparison of stable isotope values between trees with and …

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Wolverines were greatly reduced in number and possibly extirpated from the contiguous United States (U.S.) by the early 1900s. Wolverines currently occupy much of their historical range in Washington, Idaho, Montana, and Wyoming, but are absent from Utah and only single individuals are known to occur in California and Colorado. In response, the translocation of wolverines to California and Colorado is being considered. If wolverines are to be reintroduced, managers must identify appropriate source populations based on the genetic affinities of historical and modern wolverine populations. We amplified the mitochondrial control region of 13 museum specimens dating from the late …
