Single Institution Experience with Tru-Cut Renal Mass Biopsy for Diagnosing WilmsTumor
Nicholas G. Cost,Candace F. Granberg,Bruce J. Schlomer,Jonathan E. Wickiser
Urology Journal , 2013,
Abstract: PURPOSE: To evaluate the efficacy of needle biopsy for diagnosing Wilmstumor (WT) before chemotherapy. MATERIALS AND METHODS:We reviewed our institutional experience with Tru-Cut biopsy of pediatric renal masses in patients who subsequently underwent nephrectomy. We compared biopsy pathology with nephrectomy specimens to determine if biopsy accurately predicted final pathology. RESULTS: Seven children underwent Tru-Cut renal mass biopsy followed by surgical resection. In 4 patients, the final biopsy pathology was definitively read as WT and in 3 subjects, the pathology was read as WT versus hyperplastic nephrogenic rest. In all 7 patients, the nephrectomy pathology confirmed a diagnosis of WT. There were no complications after biopsy, and no patients have had local or regional recurrence.CONCLUSION: In our experience, pre-therapy Tru-Cut biopsy safely provides an adequate specimen for pathologic review in diagnosing WT.
Similar Pathogen Targets in Arabidopsis thaliana and Homo sapiens Protein Networks
Paulo Shakarian, J. Kenneth Wickiser
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0045154
Abstract: We study the behavior of pathogens on host protein networks for humans and Arabidopsis - noting striking similarities. Specifically, we preform -shell decomposition analysis on these networks - which groups the proteins into various “shells” based on network structure. We observe that shells with a higher average degree are more highly targeted (with a power-law relationship) and that highly targeted nodes lie in shells closer to the inner-core of the network. Additionally, we also note that the inner core of the network is significantly under-targeted. We show that these core proteins may have a role in intra-cellular communication and hypothesize that they are less attacked to ensure survival of the host. This may explain why certain high-degree proteins are not significantly attacked.
Light-Absorbing Products Form during the Aqueous Phase Reaction of Phenolic Compounds in the Presence of Nitrate and Nitrite with UV Illumination  [PDF]
Hao Tang, Jonathan E. Thompson
Open Journal of Air Pollution (OJAP) , 2012, DOI: 10.4236/ojap.2012.12002
Abstract: Phenolic compounds are emitted into earth’s atmosphere through industry and biomass burning events. These compounds may react in the gas or particle phase to form additional airborne pollutants. In this work, the aqueous phase chemical reactions of syringol, guaiacol, and catechol were studied in the presence of nitrate (NO-3 ) or nitrite ( NO-2) with and without UV illumination. The reactions were found to yield light absorbing products and electrospray ionization mass spectrometry (ESI-MS) experiments indicate some of the compounds formed may be the nitrated analogues of the starting organic compounds. However, infrared absorption data suggests the reaction products are composed of a complicated mixture. This suggests additional reactions occur simultaneously in solution. Treatment of the isolated reaction products with ozone (O3) suggest they are unstable and will eventually chemically decompose if/when formed in the atmosphere.
Object Relations and Relationships with Parents as Predictors of Motivation to Recover from Eating Disorders  [PDF]
Dana Warshawsky, Jonathan E. Handelzalts
Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.515180
Abstract: The lack of motivation to recover from eating disorders (ED) poses a big problem in light of literature showing the critical role motivation plays in the outcome of ED treatment. Literature exploring the factors contributing to motivation to recover is scarce. The current study aims at exploring the associations between aspects of object relations and quality of relationships with parents to the motivation for recovery in light of research suggesting an influence of these variables in the development of ED. 79 females, visitors of either “pro-anorexia” websites (in which ED are glorified as an alternative life style rather than being acknowledged as mental disorders) or “prorecovery” websites, completed a set of questionnaires online including Eat-26, Anorexia Nervosa Stages of Change Questionnaire, Quality of Relationship Inventory regarding parents and blatt’s Object Relations Inventory. Results show that while the score on EAT-26 was related to both mother and father variables, only the quality of relationship with the father is a significant variable in predicting motivation to recover from ED. Implications for treatment and further research are discussed.
The Wetting Behavior of Fresh and Aged Soot Studied through Contact Angle Measurements  [PDF]
Yiyi Wei, Qing Zhang, Jonathan E. Thompson
Atmospheric and Climate Sciences (ACS) , 2017, DOI: 10.4236/acs.2017.71002
Abstract: In this work, contact angle measurements for soot samples collected from a kerosene lantern, wood-burning fireplace, and municipal bus engine exhaust lines are reported. Contact angles for both freshly collected soot and samples treated with various doses of O3 (g), HNO3 (g), and H2SO4 (g) are considered. Use of a literature method has allowed estimation of the enthalpy of immersion (Himm) for the soot samples based on contact angle observed. Contact angles for freshly collected soot were 65 - 110 deg. indicating its hydrophobic nature. Chemical processing of soot usually resulted in smaller contact angles and large increases in immersion enthalpy. However, the dose of ozone, nitric or sulfuric acid vapor required to achieve alteration of the soot surface appeared to be considerably larger than that expected to be experienced by authentic atmospheric samples during the soot particles lifetime. The most significant variability of soot contact angle was observed for the municipal bus exhaust samples, suggesting that combustion chemistry may significantly affect wetting behavior.
Comment on “Simulation of Surface Ozone Pollution in the Central Gulf Coast Region Using WRF/Chem Model: Sensitivity to PBL and Land Surface Physics”
Jonathan E. Pleim
Advances in Meteorology , 2011, DOI: 10.1155/2011/464753
Abstract: A recently published meteorology and air quality modeling study has several serious deficiencies deserving comment. The study uses the weather research and forecasting/chemistry (WRF/Chem) model to compare and evaluate boundary layer and land surface modeling options. The most serious of the study's deficiencies is reporting WRF/Chem results for both meteorological and chemical quantities using the asymmetric convective model version 2 (ACM2). While the ACM2 is a valid model option for WRF, it has not yet been implemented for the chemical portion of the WRF/Chem model. Hence, the reported air quality modeling results using ACM2 are invalid. Furthermore, publication of these results gives the erroneous impression that the ACM2 model is not well suited for air quality applications when, in fact, it is the default boundary layer model in the community multiscale air quality (CMAQ) model.
Grasshopper Pueblo. A Story of Archaeology and Ancient Life, by Jefferson Reid and Stephanie Whittlesey. University of Arizona Press, Tucson, 1999
Jonathan E. Reyman
Bulletin of the History of Archaeology , 2001, DOI: 10.5334/bha.11205
Abstract: Grasshopper Pueblo field school closed after the 1992 summer season. Its closing marked the end of a 30-year period of survey, excavation and analysis of archaeological sites and materials as well as student education. From 1963-1992, hundreds of students were trained in the field methods and analytical models and techniques of the New Archaeology as practiced at the University of Arizona under the direction of Raymond Thompson (1963-1965), William Longacre (1966-1978), and J. Jefferson Reid (1979-1992). By the end of the 1992 summer season, Grasshopper Pueblo was, perhaps, the most thoroughly studied archaeological site in the American Southwest. As the authors note, "Although large pueblos of the American Southwest have attracted archaeologists for more than a century ... Ancient life at these special places will never be understood with as much detail as we have for Grasshopper Pueblo". Much of the detail is reported in the many published papers, nine doctoral dissertations, and two masters' theses cited by the authors, and more reports are likely to follow. As a training ground for archaeologists, Grasshopper is probably comparable in impor-tance to the Chaco Canyon field schools and excavations of the 1920s- 194Os.
Bandelier: Behind and Beyond the Journals
Jonathan E. Reyman
Bulletin of the History of Archaeology , 1996, DOI: 10.5334/bha.06202
Abstract: Bandelier: The Life and Adventures of Adolph Bandelier, by Charles H. Lange and Carroll L. Riley, 1996 A surge in publication has accompanied the recent, renewed interest in the history of American anthropol-ogy, and the Bulletin is one manifestation of this. Another notable aspect is the publication of biographies and collections of biographical essays of late-19th through mid-20th century archaeologists and other anthropologists. One interesting and sometimes surprising aspect of this output of new biography is how much more we learn about those whom we thought we knew well. For example, I have read two, book-length biographies of Ruth Benedict and Alfred Kidder as well as several biographical essays. Nevertheless, new publications about these anthropologists, and others, continue to provide additional insights and greater understanding, even though they cover much the same basic data as· earlier works. Different perspectives often yield novel ideas and conclusions, and the discovery of new, biographical and other historical data frequently requires a major reassesesment and revision of both the biography and general history. Furthermore, my own experi-ence (Reyman n.d.) suggests that, when we write biography, we also learn much about ourselves and pro-vide readers with insights about us (often unintentionally), as well as about our subjects.

Jonathan E. Reyman
Bulletin of the History of Archaeology , 1992, DOI: 10.5334/bha.02208
Abstract: This volume contains 23 papers by 41 contributors, divided into 5 sections: Hunters and Gatherers; Transitions to Sedentism; Elites and Regional Systems; Protohistoric Period: Transitions to History; and History of Southwestern Archaeology. Each section has an introduction, and there are commentaries for the second and fourth sections. Some papers are from symposia, others apparently were added to round out the collection.
The Casas Grandes World, edited by Curtis F. Schaafsma and Carroll L. Riley. University of Utah Press, Salt Lake City, 1999
Jonathan E. Reyman
Bulletin of the History of Archaeology , 2001, DOI: 10.5334/bha.11207
Abstract: Casas Grandes (Paquime) has gained prominence as the subject of books and articles since Charles C. Di Peso and his colleagues, John Rinaldo and GIoria Fenner, published their 8-volume master- work in 1974: Casas Grandes: A Fallen Trading Center of the Gran Chichimeca. The volume reviewed here contains an introduction by the editors followed by 18 essays written by 28 scholars, and organized into 4 sections: The Core Area (7); The Outer Sphere (3); The Larger View (7); and Toward a New Synthesis (I). It is dedicated to the memory of J. Charles Kelley and Daniel Wolfman, and the death of Oement Meighan, one of the contributors, is noted in the Acknowledg-ments. This volume is the product of a 1995 symposium - "The Casas Grandes Interaction Sphere: Origins, Nature, Contacts, and Legacy" - held as part of the Durango (Colorado) Conference on Southwest Archaeology.
