Acetate Causes Alcohol Hangover Headache In Rats, Christina R. Maxwell, Rebecca Jay Spangenberg, Jan B. Hoek, Stephen D. Silberstein, Michael L. Oshinsky

Department of Neurology Faculty Papers

Background

The mechanism of veisalgia cephalgia or hangover headache is unknown. Despite a lack of mechanistic studies, there are a number of theories positing congeners, dehydration, or the ethanol metabolite acetaldehyde as causes of hangover headache.

Methods

We used a chronic headache model to examine how pure ethanol produces increased sensitivity for nociceptive behaviors in normally hydrated rats.

Results

Ethanol initially decreased sensitivity to mechanical stimuli on the face (analgesia), followed 4 to 6 hours later by inflammatory pain. Inhibiting alcohol dehydrogenase extended the analgesia whereas inhibiting aldehyde dehydrogenase decreased analgesia. Neither treatment had nociceptive effects. Direct administration of acetate …

Enhancement Of Reactive Oxygen Species Production And Chlamydial Infection By The Mitochondrial Nod-Like Family Member Nlrx1, Ali A. Abdul-Sater, Najwene Saïd-Sadier, Verissa M.

Chlamydia trachomatis infections cause severe and irreversible damage that can lead to infertility and blindness in both males and females. Following infection of epithelial cells, Chlamydia induces production of reactive oxygen species (ROS). Unconventionally, Chlamydiae use ROS to their advantage by activating caspase-1, which contributes to chlamydial growth. NLRX1, a member of the Nod-like receptor family that translocates to the mitochondria, can augment ROS production from the mitochondria following Shigella flexneri infections. However, in general, ROS can also be produced by membrane-bound NADPH oxidases. Given the importance of ROS-induced caspase-1 activation in growth of the chlamydial vacuole, we investigated the …

Due Diligence And Demographic Disparities: Effects Of The Planning Of U.S.- Mexico Border Fence On Marginalized Populations, J. Gaines Wilson, Jude A. Benavides, Karen Engle, Denise Gilman, Anthony Reisinger, Jessica Spangler, Joe Lemen

School of Earth, Environmental, & Marine Sciences Faculty Publications

In the buildup to the construction the U.S.-Mexico border fence by the United States Department of Homeland Security (USDHS), much attention was drawn to security, drug enforcement, and immigration issues. However, there was little quantitative analysis regarding which populations were most likely to be affected by the proposed fence. Using a geographic information system, we classified census blocks in Cameron County, Texas into one of two categories: either ‘fence’ or ‘gap’. A total of 14 demographic factors were tested for disparities between those living in gap areas and those living in areas exposed to the fence. Twelve of fourteen factors …

Standards, Law, And Governance, Lawrence Busch

Journal of Rural Social Sciences

The last several centuries have been marked first by a tendency toward the use of standards to standardize, and then by the use of standards to differentiate. Both have been built on the legal edifice of the state. More recently, in response to the rapid rise of neoliberalism, standardized differentiation has increased in scope and has become part of a larger Tripartite Standards Regime (TSR) consisting of standards, certifications, and accreditations. Over the last half century, the TSR has grown to cover nearly every aspect of social life. In many ways this new form of governance replaces and transmutes positive …

Florida's Adolescent Literacy Policy: An Alternative Reading And Response, Diane Kroeger

USF Tampa Graduate Theses and Dissertations

In this qualitative case study, I constructed interpretations of the meanings conveyed by state-level discourse communities as they were manifested in the primary and secondary speech genres of Florida’s adolescent literacy policy. Meanings (or values, beliefs and feelings) are highly tacit understandings embedded in the language, actions and objects of policy (Yanow, 2000), and are conveyed through informal and formal speech (Bakhtin, 1986). Results revealed (a) state policy meanings convey multiple versions of literacy with a heavy focus on receptive aspects of literate practice; (b) a typology of students and their fit within the institutional system; and (c) an emphasis …

Pengaruh Book-Tax Differences Terhadap Peringkat Obligasi Di Indonesia, Vinna Christina, Yulianti Abbas, Christine Tjen

Jurnal Akuntansi dan Keuangan Indonesia

This research is aimed to analyze the influence of book-tax differences on bond ratings in Indonesia for six years of observation period (2003-2008) using the ordinal logit regression method. Variables used to proxy book-tax differences are deferred tax expenses and tax-to-book ratios. As apposed to Crabtree and Maher (2009) who found book-tax differences have a negative and significant influence on bond ratings. This research shows that large positive deferred taxes have no significant influence whereas large negative book-tax differences have a positive and significant influence on bond ratings, which means the larger negative book-tax differences from the company will increase …

Acute Abdominal Pain In Spinal Cord Injury Patient Induced By Indwelling Urethral Catheter Placed Into The Right Ureter Through The Ureteral Orifice: A Casereport, Chang-Jheng Wu, Huei-Yu Lo, Yau-Wai Wai, Han-Tin Lu

Rehabilitation Practice and Science

Diagnosis of acute abdomen in spinal cord injury (SCI) patients remains challenging. Classic peritoneal signs, such as rigid abdomen, rebounding pain and abdominal muscle guarding may be not reliable. It is still an important cause of morbidity and mortality in patients with SCI.A 45-year-old woman with SCI and 7th and 8th thoracic vertebrae fractures suffered from lower abdominal pain, fever and chills for three days. Physical examination revealed diffuse abdominal tenderness with muscle guarding. Laboratory studies showed severe leukocytosis and mild pyuria. Abdominal contrast-enhanced computed tomography scans (CTS) revealed a urinary catheter, which had been accidentally inserted into the right …

Optimized Production Of Lignin Peroxidase, Manganese Peroxidase And Laccase In Submerged Cultures Of Trametes Trogii Using Various Growth Media Compositions, F. Patrick, G. Mtui, A. M. Mshandete, A. Kivaisi

Tanzania Journal of Science

A white-rot fungus, Trametes trogii, was isolated from coastal Tanzania and screened for crude lignolytic enzymes production using Rhemazol Brilliant blue R (RBBR) dye, 2,2-azino-bis (3-ethylbenzthiazoline)-6-sulfonate (ABTS) and guaiacol in a semi-solid medium. Lignin peroxidase (LiP), manganese peroxidase (MnP) and Laccase (Lac) were detected by pyrogallol and !- napthol solutions, respectively on the guaiacol supplemented solid media. The effect of temperature, pH, carbon, nitrogen, Cu2+, 2,5-xylidine, ferulic acid, varatryl alcohol and Mn2+ in submerged culture fermentations were investigated for maximum enzymes production. After 7 days of incubation, 72-100% oxidation of RBBR, ABTS and guaiacol was observed. With optimized culture conditions, …

Phylogenetic Relationships Of The Metazoan Parasites Of The Clariid Fishes Of Lake Victoria Inferred From Partial 18s Rdna Sequences, C. J. Mwita, G. Nkwengulila

Tanzania Journal of Science

Phylogenetic relationships among twenty two metazoan parasites recovered from seven species of clariid fish from Lake Victoria were analysed using partial 18S rDNA sequences. The 18S rDNA gene was amplified by polymerase chain reaction, directly sequenced, aligned and phylogenies inferred using maximum parsimony. Heuristic bootstrap MP searches yielded one most parsimonious tree (CI = 61%, HI = 39%), which showed that clariid parasites are monophyletic at higher taxonomic levels (Cestodea, Nematodea, Digenea and Crustacea). However the position of two trematodes (Allocredium mazoensis and Clinostomum sp.) and a nematode (Contracaecum sp.) were not stable. Despite the present findings, the study utilised …

Can Tax Expenditure Analysis Be Divorced From A Normative Tax Base?: A Critique Of The 'New Paradigm' And Its Denouement, J. Clifton Fleming Jr., Robert J. Peroni

Faculty Scholarship

Tax expenditure analysis (TEA) requires a baseline for identifying tax provisions that provide subsidies or incentives instead of serving to define the tax base and to implement the tax. With respect to the federal income tax, the baseline historically has been the Schanz-Haig-Simons (SHS) definition of income with a few modifications. Critics have continuously and strongly attacked TEA by characterizing the SHS baseline as unprincipled, imprecise, and insufficiently related to our hybrid income/consumption tax system as it actually exists. Since the baseline is hopelessly defective, so the critics argue, TEA is fatally dysfunctional and the results of its application to …

The Major Cause Of Observed Erosion Surge On The Beaches North Of Dar Es Salaam City, N. Nyandwi

Tanzania Journal of Science

Surges in coastal erosion north of Dar es Salaam city have been documented from 1977 to the early 1980s and around 1997/98. Analysis of the wind data shows that the documented increase in coastal erosion coincided with increased wind speeds. Extreme winds in excess of 10-11 m s-1 were experienced during 1976-78, 1984 and after 1996. Their coincidence with extreme high tides produced the high erosion rates. Using beach profile data for the years 1998-2000 the evolution of the beach profile with the changing monsoon winds and sediment input by rivers could be demonstrated. The beach erosion took place during …

Geomorphological Potential Of Coelacanth Habitat Across Mozambique-Tanzania Border, N. Nyandwi

Tanzania Journal of Science

The coelacanth is a new fish in Tanzania. It was first discovered in September 2003 after it was spotted by a tourist in a fish market. It was caught by fishermen in the deep waters off Songo Mnara Island offshore of Kilwa Masoko Town in Southern Tanzania. The find potentially added southern Tanzania to the list of known coelacanth areas of the southern Western Indian Ocean Region. Observed current conditions indicate that the waters are swept by strong (2 m/sec) northward flowing current. This suggests that there must exist hideouts for the fish, such as caves in canyons and overhangs. …

The samples in this research are the non-governmental rural banks (Bank Perkreditan Rakyat) in Central Java. The financial performance of the BPR is measured by the ratio of NPL, KPMM, LDR, and ROA. CG mechanisms are measured by its managerial ownerships, the proportion of the outside directors, and the number of board of …

Masyarakat Dayak Di Kesultanan Kutai Pada Abad Ke-19, Ita Syamtasiyah Ahyat

Paradigma: Jurnal Kajian Budaya

The Dayak people of Kalimantan, who have occupied in the territory of Kutai Sultanate, the water kingdom along the riverbank and the upper course of the Mahakam, live by trading in the river ways. The Dayak people consist of eleven tribes; the Kenyah, Kayan, Bahau, Tunjung, Benua, and Bentian, were only some of them. They were governed under the sovereignty of the Sultanate of Kutai which had made easier for the colonial government to subdue the territory. However, the people of Kutai found ways to accept the Dayak, and vice versa. They sold forest produce, such as resin, birds’ nests,rice, …

The Market Orientation Of Slovenian Companies: Two-Group Comparisons, Mateja Bodlaj, Iča Rojšek

Economic and Business Review

The purpose of the presented empirical study was to examine market orientation between groups of companies in terms of three company characteristics, i.e. main business sector, company size, and type of the market, and three environmental characteristics, i.e. market turbulence, technological turbulence and competitive intensity. Market orientation is analysed by distinguishing between a cultural and behavioural perspective and by distinguishing between a responsive and proactive form. Comparisons between groups of companies are made by testing invariant latent mean structures. The analysis of 325 Slovenian companies reveals that the particular market orientation dimensions only differ when different levels of market and …

What Determines The Co-Operative Potential For Firms In Western European And Cee Border Regions? A Comparative Micro-Level Analysis, Birgit Leick

Economic and Business Review

The present article investigates whether Eastern European enlargement influences the co-operative potential of firms in the borderland between Western and Central Eastern Europe more than of other firms, i.e. of those not being located in the borderland. Based on theoretical arguments as well as empirical evidence, we build a micro-level framework of factors, which determine a firm’s likelihood of cross-border business co-operation. Using logistic regression, this framework is empirically tested and compared for two cross-sectional datasets of firms located in the border regions in Northern Bohemia (the Czech Republic) and Saxony (East Germany).

Determinants Of Firm Entries: Empirical Evidence For Slovenia, Dijana Močnik

Economic and Business Review

We empirically investigate the determinants of new firm formations on Slovenian data set for the 6-year period across statistical regions. Analyzed are the relationships of the determinants classified into five groups: demand, unemployment, industrial restructuring, local financial capital, and knowledge concentration. We find a positive and significant impact of GDP p.c., unemployment rate, productivity growth and a negative relationship for employment density. Results show that some regions have significantly worse conditions for start-up firms than others. Practical implications of this study would allow policy makers to better understand the dynamics in new firm formations.

Oracle And Multiple Robustness Properties Of Survey Calibration Estimator In Missing Response Problem, Kwun Chuen Gary Chan

UW Biostatistics Working Paper Series

In the presence of missing response, reweighting the complete case subsample by the inverse of nonmissing probability is both intuitive and easy to implement. However, inverse probability weighting is not efficient in general and is not robust against misspecification of the missing probability model. Calibration was developed by survey statisticians for improving efficiency of inverse probability weighting estimators when population totals of auxiliary variables are known and when inclusion probability is known by design. In missing data problem we can calibrate auxiliary variables in the complete case subsample to the full sample. However, the inclusion probability is unknown in general …

Modification And Improvement Of Empirical Likelihood For Missing Response Problem, Kwun Chuen Gary Chan

UW Biostatistics Working Paper Series

An empirical likelihood (EL) estimator was proposed by Qin and Zhang (2007) for a missing response problem under a missing at random assumption. They showed by simulation studies that the finite sample performance of EL estimator is better than some existing estimators. However, the empirical likelihood estimator does not have a uniformly smaller asymptotic variance than other estimators in general. We consider several modifications to the empirical likelihood estimator and show that the proposed estimator dominates the empirical likelihood estimator and several other existing estimators in terms of asymptotic efficiencies. The proposed estimator also attains the minimum asymptotic variance among …
