description: A simple, versatile single step method to synthesize phosphine-stabilized gold nanoparticles (TPP-AuNPs) of narrow size distribution using the mild reducing agent 9- borabicyclo [3.3.1]nonane (9-BBN) was developed. This single step procedure produces particles of less than 2 nm in diameter. The use of 9-BBN offers many advantages over other commonly used reducing agents. The particle growth process can be controlled and the particle size can be tuned by carefully controlling the conditions under which the reduction takes place. In addition, the approach is inexpensive and greener because the use of phase transfer reagents and the attendant rigorous purification steps are eliminated. Since 9-BBN is a mild reducing agent, the synthesis is compatible with a wide variety of ro-functionalized capping ligands. TPP-AuNPs can be used as precursors to AuNPs functionalized with various ligands by way of ligand exchange reactions to obtain AuNPs stabilized with different rnfunctionalized alkythiols, other phosphines and bipyridines. The in-situ addition of capping ligands other than TPP to the reaction was demonstrated to reduce the need for ligand exchange reactions. TPP-AuNPs also are soluble in water, thereby expanding their potential applications. The stability of TPP-AuNPs in water as a function of salt and sodium borohydride concentration, solvents with different dielectric constants, pH and temperature was investigated. The NPs were found to be stable in water as evidenced by UV-vis spectroscopy, TEM imaging and zeta potential measurements over time. Addition of salt and NaBH4 induced aggregation of the NPs. The catalytic activity of TPP-AuNPs in aqueous solution was investigated using two model reactions: reduction of 4-nitrophenol by NaBH4 and the electron transfer reduction of hexacyanoferrate (III) by NaBH4. The rate constants for the reduction reactions were found to depend on the surface area of the TPP-AuNPs. The TPP-AuNPs were recycled, however aggregation of the NPs was observed at the end of the reduction. The kinetic data for both reactions for the unsupported TPP-AuNPs was better compared with that for supported AuNP catalytic systems, indicating the good catalytic activity of TPP-AuNPs for these reactions.

Note. A. Schmidt (1922a: 74) is the first to mention Canthon curvodilatatus for French Guiana and Venezuela. All subsequent records of these locations for this species (Blackwelder 1944: 199; Martínez 1949a: 183; Vulcano and Pereira 1964: 609) appear to be based on this publication. This species appears to have a more southern distribution, and as we have found no additional records or specimens from the research area, its occurrence there remains to be confirmed.

Anaplerotic therapy in propionic acidemia

propionic acidemia

description: Propionic acidemia is a rare metabolic disorder caused by a deficiency of propionyl- CoA carboxylase, the enzyme that converts propionyl-CoA to methylmalonyl-CoA. Patients with propionic acidemia cannot metabolize propionic acid, which sequesters oxaloacetate from the Krebs cycle to form methylcitric acid. This may lead to a deficiency in Krebs cycle intermediates. Our study looked at whether adding glutamate, citrate, or ornithine α-ketoglutarate (chemicals that could fill up the Krebs cycle as anaplerotic agents) to patients' diets affected plasma levels of glutamine and ammonia, and the urinary excretion of Krebs cycle intermediates. We also looked at developmental markers and hospitalizations to determine clinical efficacy. Each supplement was administered daily for four weeks with a two week washout period between supplements. The supplement that produced the most favorable changes was supplemented for 30 weeks following the initial study period. Levels of Krebs cycle intermediates, α-ketoglutarate, succinate, and fumarate increased significantly compared to baseline during citrate supplementation. Glutamine levels did not decrease with increasing ammonia levels. Glutamate and alanine levels significantly increased, rather than decreased with increasing ammonia levels. There was a significant direct correlation between lysine and ammonia. Hospitalizations per year decreased significantly in the 2 years following the study compared to the 2 years before and during the study. These results indicate that citrate entered the Krebs cycle providing successful anaplerotic therapy by increasing levels of the downstream intermediates of the Krebs cycle: -ketoglutarate, succinate and fumarate. Citrate supplements appear to be a safe and might have contributed to reducing hospitalizations in patients with propionic acidemia.

description: This dissertation presents experimental and computational investigations of electrolyte negative differential resistance, nanoparticle dynamics in nanopores, and nanobubble formation at nanoelectrodes. Chapter 1 provides an introduction to negative differential resistance and other nonlinear electrical responses in nanopores, an overview of resistive pulse analysis of nanoparticles using nanopores, and current nanobubble research. Chapter 2 describes the first example of electrolyte negative differential resistance (NDR) discovered in nanopores, where the current decreases as the voltage is increased. The NDR turn-on voltage was found to be tunable over a ~1 V window by adjusting the applied external pressure. Finite-element simulations yielded predictions of the NDR behavior that are in qualitative agreement with the experimental observations. Chapter 3 presents the extension of NDR to an aqueous system and demonstrates the potential for chemical sensing based on NDR behavior. Solution pH and Ca2+ in the solution were separately employed as the stimulus to investigate the surface charge density dependence of the NDR behavior. The NDR turn-on voltage was found to be exceedingly sensitive to the nanopore surface charge density, suggesting possible analytical applications in detecting as few as several hundred of molecules. Chapter 4 discusses the technique of controlling the dynamics of single 8 nm diameter gold nanoparticles in nanopores, which is extended from traditional resistive pulse analysis of nanoparticles. A pressure was applied to balance electrokinetic forces acting on the charged Au nanoparticles as they translocate through a ~10 nm diameter orifice at an electric field. This force balance provides a means to vary the velocity of nanoparticles by three orders of magnitude. Finite-element simulations yielded predictions in semiquantitative agreement with the experimental results. Chapter 5 reports the electrochemical generation of individual H2 nanobubbles at Pt nanodisk electrodes immersed in a H2SO4 solution. A sudden drop in current associated with the transport-limited reduction of protons was observed in the i-V response at Pt nanodisk electrodes of radii less than 50 nm. Finite element simulation based on Fick's first law, combined with the Young-Laplace equation and Henry's Law, were employed to investigate the bubble formation and its stabilization mechanism.

description: In providing children at risk for reading difficulties with the necessary skills to be successful readers in school age programs, early childhood educators in high-quality preschool programs facilitate the development of emergent literacy and oral language abilities through language-rich environments. However, most teachers in preschool settings rarely use strategies necessary to build these skills in their students. Professional development efforts need to employ the most effective methods for providing early childhood educators with the knowledge, skills, and strategies to increase emergent literacy skills. Follow-up techniques that successfully support teachers in the transfer of new strategies to their classrooms are an important component of professional development training. A multiple-baseline design across participants was used in this study to examine the effects of an expert coaching model, which included teacher selfevaluation of videotaped observations and reflection on implementation of open-ended questions and expansions, on (a) implementation of strategies, (b) generalization of strategies to other settings, (c) teacher attitudes towards the coaching model, and (d) student outcomes. Data analysis showed that self-evaluation maintained or increased the use of teaching strategies, with the addition of modeling and guided practice bringing about continued improvement over baseline values. The use of open-ended questions generalized to other settings, increasing over baseline in the majority of participants. Teachers indicated the self-evaluation process was useful in improving their use of oral language development strategies. The majority of students increased the use of one-word and two or more-word utterances, which resulted in an overall increase in words per minute. Implications for professional development designers and recommendations for future research are discussed.

HIV Risk Behaviors, HIV Testing, and Entry into Medical Care in Utah
Creators: name: Lowe, Michael Thomas
Publisher: name: University of Utah

description: Early diagnosis of HIV infection is beneficial for improved health outcomes on the individual level and for HIV prevention on the community level. Using data from a survey of men who have sex with men (MSM) and from the electronic HIV/AIDS reporting system (eHARS) at the Utah Department of Health, I explored high-risk behaviors and HIV testing among men MSM in Utah and entry into medical care for newly diagnosed individuals in Utah. Using a survey of 986 MSM, the associations between high-risk behaviors, HIV testing, and having a regular medical care provider were examined. Sixty percent of the MSM had a regular provider and 53% had been tested for HIV in the last year. For the three sexual risk behaviors (number of partners, type of partner, and use of condoms during anal sex) there was no association with having a medical provider. However MSM who inject drugs were less likely to have a medical provider. Having an HIV test in the last year was only associated with having a regular medical care provider if the patient disclosed his sexual orientation to the provider. Based on these findings, I recommend that interventions to improve communication between a patient and his provider be developed, and if a provider is uncomfortable asking about sexual history, then the provider should universally screen for HIV. Survival analysis was used to evaluate the time from initial HIV diagnosis to entry into medical care for 522 newly diagnosed individuals. Of these individuals, 65% iv had entered medical care within the first 90 days while for 14% there was no evidence of ever entering care. The only characteristic associated with delayed entry to care was having no risk identified (NRI) for transmission. This finding suggests that individuals with NRI may benefit from more extensive post-HIV counseling.

description: The essential oil components of fresh and dry aerial parts of Callistemon citrinus, monthly harvested from Iran during a year, were compared. The EO contents of dry plant samples were dramatically higher than the fresh materials. The dry sample collected in March with 1.10 ± 0.04% and fresh in August with 0.16 ± 0.01% (w/w), possessed the highest and lowest EO yields, respectively. From thirty-two identified aroma phytoconstituents, 1,8-cineole was the major compound with quantity variation of 60.01% in dry sample collected in January and 33.92% in fresh from August. In summer, the amount of α-pinene as the second predominant volatile terpenoid was raised, while dry sample in August (46.92%) was the richest. The present study explicitly demonstrates the impact of harvesting period on volatile oil contents of C. citrinus and the findings are considerable to obtain the favourite EO compositions for consuming in food and phyto-pharmaceutical industries.

description: As computer assisted instruction (CAI) becomes increasingly sophisticated, its appeal as a viable method of literacy intervention with young children continues despite limited evidence of effectiveness. The present study sought to assess the impact of one such CAI program, Imagine Learning English (ILE), on both the receptive vocabulary and early literacy skills of 284 kindergarten students, including English language learners using a 2 x 2 cross-over research design over a period of a full school year. In each semester, students received either the ILE treatment or "other" treatment (integrated core curriculum including science, social studies, art, music, physical education). Specifically, the study sought to answer two questions: (a) How do the literacy skills of kindergarten students, including English language learners and monolingual children, who receive instruction using ILE compare with the literacy skills of kindergarten students who receive "other" classroom instruction; (b) how do the vocabulary skills of the same kindergarten students who receive instruction using ILE compare with the vocabulary skills of those who receive "other" classroom instruction? Results of the t-tests from this within-subjects design showed no treatment differences on outcome measures (PPVT-4 for receptive vocabulary and DIBELS Next for early literacy) between students when they participated in the ILE program and when they participated in "other" classroom activities, regardless of amount of time spent on this CAI program. These same results held true for English language learners for whom the program was originally designed. A strong period effect, however, was detected, with the treatment administered during period 1 (i.e., either ILE or "other" instruction) having a more positive effect on student language and literacy learning than the treatment that was administered during period 2. Possible explanations for this significant period effect are provided as well as cautions for the ongoing use of CAI programs such as ILE in early literacy education. Finally, recommendations for future research are set forth.

description: The Neotropical Neoponera laevigata species-group is revised. This group can be separated from others in the genus by means of a new key to Neoponera species–groups. We propose two new species, N. gojira sp. nov., and N. mashpi sp. nov., the latter being usually confused with its putative sister species, N. laevigata (Smith). This small, termite-feeding species-group now contains five taxa. We provide comprehensive redescriptions for the known castes of the three previously known species, together with images and notes about intraspecific morphological variation, biology, and distribution of the taxa here treated. We reveal the external morphological features of the genitalia of the known males. This is the first contribution en route to a better understanding of the systematics of this charismatic ponerine genus.

description: Central to the direction China will take in the future is the role of capital markets within a  bank-centered financial structure, and its continued development is the country's most  important task for stimulating long term economic growth. This paper first introduces the  models of financial structure from the developed world and surveys the experience of  three relevant European transition economies. Next, the paper presents a brief historical  overview of Chinese capital markets in the context of the last century. A description and  analysis of the current efficacy of the Chinese financial system is then offered, followed  by an examination of the system's ability to allocate risk and wealth. In conclusion,  significant changes are recommended for the country's banking system as a means to  supply capital to a rising entrepreneurial class. Policies and economic reforms in venture  capital and private equity alongside of capital market improvements will spur balanced  growth in the short and long term.

description: Pharmacological studies show spasmolytic activity for various species of Varronia. Thus, based on the taxonomy criteria, the aim of this study was to contribute to chemical and biological knowledge, especially regarding the evaluation of spasmolytic activity of the ethanolic extract from Varronia dardani leaves (VD-EtOHL) on rat aorta and trachea, guinea-pig ileum and rat uterus. Were used High and Medium Performance Liquid Chromatography. Wistar rats and guinea-pigs were used for pharmacological assays. All experimental protocols were approved by Animal Ethics Committee of UFPB (126/2017). Two chalcones (pinostrobin chalcone and gymnogrammene), five flavanones (pinocembrin, isosakuranetin, pinostrobin, sakuranetin 4’-methyl ether, naringenin) and a flavonoid glycosilated (astragalin) were identified based on data of 1H and 13C Nuclear Magnetic Resonance. This study also showed that VD-EtOHL has a non-selective spasmolytic activity, presenting greater relaxing potency in rat uterus, suggesting that flavonoids isolated from VD-EtOHL may be responsible for spasmolytic activity of this extract.

Year: 2014

description: Abnormalities in language and communication, auditory sensitivity, and complex information processing are associated with autism, yet the neural underpinnings are unknown. The studies in this dissertation examine neurodevelopment of several brain regions implicated in these abnormalities. We first examine age-related changes in midsagittal corpus callosum area in a large cross-sectional cohort from early childhood to adulthood. Increased variability in total corpus callosum area and atypical regional development in the rostrum and isthmus are found in autism compared with typical controls. In autism, larger areas are associated with reduced severity of autism behaviors, higher intelligence, and faster speed of processing, providing support to theories of underconnectivity in the autism brain. Longitudinal maturation of Heschl's gyrus gray matter and white matter and planum temporale during childhood and adolescence in autism and a typically developing sample are then described. Despite previous crosssectional studies reporting typical Heschl's gyrus structure in autism, reduced developmental trajectories in the right gray matter and atypical white matter maturation are identified. Our longitudinal findings also expand on previous reports of reduced planum temporale asymmetry in autism by showing that the reduced asymmetry develops during later childhood and adolescence. In addition to the case-control comparisons, different developmental trajectories in those individuals with autism with delayed versus early language onset in Heschl's gyrus white matter and planum temporale asymmetry iv are apparent. Finally, individuals with autism exhibit associations between smaller Heschl's gyrus volumes and reduced auditory sensitivity and higher language function, and smaller planum temporale volumes associated with increased vocabulary aptitude. Our findings highlight the importance of longitudinal studies of brain development and examining behavioral profiles of individuals to identify functional and maladaptive pathological neurodevelopment.

description: Phytochemical examination of Clausena lenis Drake (Rutaceae), collected in Thailand, led to the isolation of seven coumarins, four furoquinolines, two amides, and one flavonoid glycoside. Four of these compounds, one coumarine derivative named as gravelliferone A (3), two furoquinoline derivatives (kokusagenin A (8) and B (9)) and one amide, clausenalansamide H (13), are reported for the first time. Compound 3 was isolated from the root bark, compound 8 from the stem bark and compounds 9 and 13 from the leaves. The molecular structures of all isolated compounds were established by means of NMR experiments combined with mass spectrometry. Preliminary tests of the lipophilic stem bark extract against various human pathogenic bacteria strains revealed promising effects against Staphylococcus aureus ATCC 43300.

description:
[FeCp{N(SiMe₃)₂}] is a high-spin complex with four unpaired electrons according to SQUID magnetometry and Mößbauer spectroscopy. Its reactions with 4-dimethylaminopyridine (DMAP) and NnPr4X (X = Cl, Br) respectively afford [FeCp{N(SiMe₃)₂}(DMAP)] (6), NnBu₄[FeCpCl{N(SiMe₃)₂}] (7), and NnPr₄[FeCpBr{N(SiMe₃)₂}] (8). 7 and 8 react with formamidinium tetrafluoroborates fc[(NCH₂R)₂CH][BF₄] (fc = 1,1′-ferrocenylene; R = Ph, Mes) at room temperature in THF to furnish [FeCpX{fc[(NCH₂R)₂C]}] (4: X = Cl, R = Mes; 10: X = Br, R = Mes; 11: X = Cl, R = Ph; 12: X = Br, R = Ph), which contain a ferrocene-based NHC ligand. No formation of 10 from fc[(NCH₂Mes)₂CH][BF₄] and 8 takes place under the same mild conditions in toluene, instead leading to the isolation of fc[(NCH₂Mes)₂CH][FeCpBr{N(SiMe₃)₂}] (9). In contrast to its halide adducts 7 and 8, [FeCp{N(SiMe₃)₂}] is inert towards formamidinium tetrafluoroborates. It reacts readily, however, with formamidinium halides, affording [FeCpCl(IPr)] (1, IPr = 1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene) with 1,3-bis(2,6-diisopropylphenyl)imidazolium chloride and [FeCpI(BzIMe)] (2, BzIMe = 1,3-dimethylbenzimidazolin-2-ylidene) or, depending on the crystallisation conditions, [FeCp(BzIMe)2][FeCpI2] (3) with 1,3-dimethylbenzimidazolium iodide, in accord with an equilibrium of the type 2 [FeCpX(NHC)] ⇄ [FeCp(NHC)₂]+ + [FeCpX₂]−. The major product formed with fc[(NCH₂Mes)₂CH]Cl is fc[(NCH₂Mes)₂CH][FeCpCl₂] (5) instead of the expected NHC complex [FeCpCl{fc[(NCH₂Mes)₂C]}] (4). Halide abstraction reactions attempted with [FeCpX{fc[(NCH₂R)₂C]}] afforded only intractable material. [FeCp{fc[(NCH₂Ph)₂C]}₂][PF₆] (13) was serendipitously obtained in this context in trace amounts from 12 and Tl[PF₆]. Compounds 1–13 were structurally characterised by single-crystal X-ray diffraction. Metric parameters reveal different electronic configurations for 1 and its solvate 1·0.5 benzene (two vs. four unpaired electrons).

description: Historically, teaching first-year composition has been integral to graduate education in English and writing studies (Latterell, 1996). However, as best practices for teaching writing evolve, so do practices for training graduate students to teach it. Graduate instructor training (GIT) now encompasses not only writing pedagogy education (WPE), but also professional development and mentoring for careers both in and outside of academia. To date, research has focused on GIT programs sited at institutions that house doctoral programs, leaving out most master’s-granting institutions, even though they are far more numerous and serve many students. These institutions serve student populations with varied career goals, especially now as the purpose of a master’s degree in English and writing studies is evolving (Strain & Potter, 2016). I conducted a three-phase study designed to highlight graduate instructor training programs for first-year composition at master’s-granting institutions in the United States. In my first phase, I developed a database of all master’s-granting institutions with English and writing studies programs (476 institutions) utilizing NCES, Carnegie Classification, and publicly available website data. I then surveyed writing program administrators (WPAs) and other faculty in the programs (n=41) that employed graduate student instructors (GSIs), focusing on program conditions, the first-year composition course, and the responsibilities of GSIs. In phase three, I conducted interviews with faculty (n=13) to gain more insight on curricular and administrative choices within their institutional contexts. My results show that faculty design curricula, training, and mentoring prioritizing students’ needs. WPE serves as pedagogical preparation and as a site of disciplinary enculturation. Participants share a desire for more resources that focus on designing curricula and programs within limited institutional resources. Additionally, as a discipline we need more comprehensive methods for documenting programmatic practices.
