Parkinson's Disease. Clinical And Electrophysiological Evaluation, Muneera A. Al-Bunyan

Saudi Medical Journal

OBJECTIVE: Identification of the clinical spectrum and the electrophysiological responses of a Saudi population with Parkinson9s disease as opposed to a matched normal population. METHODS: Fifty four subjects (41 males and 13 females) were selected for the study. The patients were clinically evaluated for the occurrence of Parkinson9s disease symptoms, as well as other associated medical conditions. All patients had brain computerized tomography scans. Electrophysiological tests were performed on all patients using the Medelec ST 10 Sensor 59394 Model. These tests included somatosensory evoked response of median nerves, brain stem auditory evoked responses and visual evoked responses. The significant differences …

Prevalence Of Food Allergy In Asthmatic Patients, Bahaa A. Aba-Alkhail, Fathi M. El-Gamal

Saudi Medical Journal

OBJECTIVE: This study was conducted to assess the role of clinical sensitivity to food on the pattern of bronchial asthma. METHODS: A total of 1341 patients with asthma were included in the present study. The clinical sensitivity to food and its relation to respiratory symptoms were assessed cross-sectionally (using detailed questionnaires), and longitudinally during their regular visits to the asthma clinic using diet diary. Total IgE was determined for a subsample of the patients (No = 392). RESULTS: The prevalence of clinical sensitivity to food was 29%; about 2 thirds of the patients had high total IgE level. Asthmatic patients …

An Unusual Association Between Oral Sarcoma And Bulbar Palsy, Tayseer M. Zein, Eivind J. Carlsen, Zein M. Mirghani

Saudi Medical Journal

A 90 year old male presented with symptoms and signs of right lower cranial nerves palsy. A small mass was found on the right side at the back of his mouth. Light microscopy and histoimmunochemical studies of the biopsy of the mass showed an alveolar soft part sarcoma arising from the right myohyoid muscle. The unusual location and presentation of this rare tumor is discussed.

Visual Loss After Coronary Artery Bypass Surgery, Reham I. Sha’Aban, Wafa M. Asfour

Saudi Medical Journal

Anterior ischemic optic neuropathy is caused by microvascular occlusion of the prelaminar or laminar portion of the optic nerve head. The main types are arteritic, non-arteritic, and autoimmune. Few cases were reported following coronary artery bypass surgery. A 63-year-old man, who is both diabetic and hypertensive, underwent coronary artery bypass graft complicated postoperatively by sudden visual loss in his right eye. The diagnosis was non-arteritic anterior ischemic optic neuropathy. Possible predisposing factors were crowded disc and internal carotid artery stenosis.

Schmidt's Syndrome In A Saudi Family, Faiza A. Qari, Saleh Damnan

Saudi Medical Journal

We present 3 patients from a Saudi family who are presented with polyglandular autoimmune syndrome type 2. They have Addison9s disease with either autoimmune thyroid disease or insulin dependent diabetic mellitus. Although this syndrome is rare, the incidence among Saudi Arabia or the Arab population is not known.

Thyroiditis Induced By Interferon In Dialysis, Ali S. Al-Harbi, Hatem Mansy, John Moloney

Saudi Medical Journal

We describe a dialysis patient who acquired acute Hepatitis C infection. Her primary renal disease was systemic lupus erythromatosis. She was having goitre but clinically euthyroid and her thyroid function test was normal. To avoid long term complications of Hepatitis C we elected to treat her with Interferon 3 million units subcutaneously 3 times a week. During treatment she developed some transient side effects initially which subsided but later she felt pressure symptoms around her neck. When we checked her TSH and thyroid antibodies these were elevated. Though this could be related to HCV, rarely, but we think the thyroid …

Formation Of Direction Selectivity In Natural Scene Environments, Brian S. Blais, Leon N. Cooper, Harel Z. Shouval

Science and Technology Department Faculty Journal Articles

Most simple and complex cells in the cat striate cortex are both orientation and direction selective. In this article we use single-cell learning rules to develop both orientation and direction selectivity in a natural scene environment. We show that a simple principal component analysis rule is inadequate for developing direction selectivity, but that the BCM rule as well as similar higher-order rules can. We also demonstrate that the convergence of lagged and nonlagged cells depends on the velocity of motion in the environment, and that strobe rearing disrupts this convergence, resulting in a loss of direction selectivity.

Micronutrient And Iron Supplementation And Effective Anti-Malarial Treatment Synergistically Improve Childhood Anaemia, H. Ekvall, Zul Premji, A. Bjorkman

Pathology, East Africa

The control of childhood anaemia in malaria holoendemic areas is a major public health challenge for which an optimal strategy remains to be determined. Malaria prevention may compromise the development of partial immunity. Regular micronutrient supplementation has been suggested as an alternative but its effectiveness remains unsettled. We therefore conducted a randomised placebo-controlled intervention trial with 207 Tanzanian children aged 5 months to 3 years on the efficacy of supervised supplementation of low-dose micronutrients including iron (Poly Vi-Sol with iron) three times per week, with an average attendance of ≥ 90%. The mean haemoglobin (Hb) level increased by 8 g/l …

Generalization Of Social Anxiety To Sporting And Athletic Situations: Gender, Sports Involvement, And Parental Pressure, Peter J. Norton, James A. Burns, Debra Hope, Bruce K. Bauer

Department of Psychology: Faculty Publications

Although researchers have documented that social anxiety may occur in a wide range of interpersonal and performance situations, little attention has been paid to the potential influence of social anxiety on participation in athletics or physical activity. The performance demands of sport and potential social evaluative nature of exercise make it likely that social anxiety would generalize to these situations. Given the physical and psychological benefits of engaging in regular physical activity, avoidance of such activities by socially anxious individuals may have profound health consequences. One-hundred and eighty undergraduate university students completed a battery of standardized social anxiety measures, and …

Expression Of A Dominant-Negative Mutant Of P21ras Inhibits Induction Of Nitric Oxide Synthase And Activation Of Nuclear Factor-Kb In Primary Astrocytes, Kalipada Pahan, Xiaojuan Lu, Michael J. Mckinney, Charles Wood, Faruk G. Sheikh, John R. Raymond

School of Biological Sciences: Faculty Publications

The present study underlines the importance of p21ras in regulating the inducible nitric oxide synthase (iNOS) in primary astrocytes. Bacterial lipopolysaccharides induced the GTP loading of p21ras, and the expression of a dominant-negative mutant of p21ras (Dp21ras) inhibited lipopolysaccharide-induced GTP loading in rat primary astrocytes. To delineate the role of p21ras in the induction of iNOS, we examined the effect of Dp21ras on the expression of iNOS and the production of nitric oxide. It is interesting that expression of Dp21ras markedly inhibited the production of nitric oxide and the expression of iNOS in lipopolysaccharide- and pro-inflammatory cytokine (tumor necrosis factor-a, …

Plant Quality And Spider Predation Affects Grasshoppers (Acrididae): Food-Quality-Dependent Compensatory Mortality, Mark A. Oedekoven, Anthony Joern

School of Biological Sciences: Faculty Publications

For insect herbivores, population responses reflect interactions among multiple factors, including abiotic conditions, food plant availability, and biotic interactions guided by food limitation and natural enemies. In this set of field experiments, we evaluated the interactive, dynamic effects of limited food supply and predation from wolf spiders (Lycosidae) on mortality in Ageneotettix deorum, a common grasshopper (Acrididae) from North American sandhills grasslands. We attempted to determine whether the combined effects of food availability and spider predation on mortality were (1) noncompensatory, with the effects of each factor summing to determine ultimate population size, or (2) compensatory, where the effect …

Biosystematics And Evolution Of The Triatominae = Biossistemática E Evolução De Triatomíneos, Christopher J. Schofield

Harold W. Manter Laboratory of Parasitology: Library Materials

Abstract

In this paper we summarize the systematics of the 130 currently recognized species of Triatominae and the key features of their evolutionary background. There is increasing evidence that the subfamily has polyphyletic origins, with the various tribes and species groups probably arising from different reduviid lineages in relatively recent times.

Resumo

Neste trabalho resume-se a sistemática das 130 espécies de triatomíneos atualmente reconhecidas, com os elementos principais de sua evolução. Existem evidências crescentes para a origem polifilética da subfamília. As diferentes tribos e grupos de espécies que a compõem teriam surgido recentemente, a partir de diferentes linhagens de reduviídeos.

Codes And Curves, Judy L. Walker

Department of Mathematics: Faculty Publications

When information is transmitted, errors are likely to occur. Coding theory examines effi cient ways of packaging data so that these errors can be detected, or even corrected. The traditional tools of coding theory have come from combinatorics and group theory. Lately, however, coding theorists have added techniques from algebraic geometry to their toolboxes. In particular, by re-interpreting the Reed- Solomon codes, one can see how to defi ne new codes based on divisors on algebraic curves. For instance, using modular curves over fi nite fi elds, Tsfasman, Vladut, and Zink showed that one can defi ne a sequence of …

Recognition Of Treponematoses In Post Repatriation X Ray And Cd Rom Nebraska Record, Karl J. Reinhard, Bruce Rothschild, Christine Rothschild, Larry Martin

Karl Reinhard Publications

Repatriation has compromised the opportunity to directly examine skeletons and to apply new diagnostic criteria and techniques. Pre-repatriation approaches to non-metric data acquisition, must make a number of assumptions: ( I ) Phenomena must be correctly identitied and segregated; (2) Criteria for severity must be specific to the phenomena studied; and (3) As criteria for disease rewgnition may change with time, it is valuable only as long as the raw data is also recorded. As part of data preservation, x-rays and CD-ROM images were recorded for skeletons trom Nebraska sites undergoing repatriation. This report concentrates on four of them 250K …

The Role Of Mummy Studies In Paleoparasitology, Adauto Araujo, Karl J. Reinhard, Luiz Fernando Ferreira

Karl Reinhard Publications

Paieoparasitology has advance during the past decade to the status of a statistically based science focused on problems of disease ecology and geographic distribution of parasitism. For most of its development, paleoparasitology has focused on the analysis of coprolites and latrine sediments. During the past few years, mummies have been increasingly included in paleoparasitology studies. We evaluate in this paper the interpretive value of mummies relative to other sources of paleoparasitological data.

Archaeoparasitology, Karl Reinhard

Karl Reinhard Publications

The field devoted to the identification of parasite remains in the archaeological record and the reconstruction of past human-parasite interactions. Parasitic disease has always been a major problem. Recent summaries of the prevalence of parasitic diseases in the world today show that there are 4.5 billion infections with all species of parasitic worm, 1 billion infections with giant intestinal roundworm (Ascaris lumbricoides), 750,000,000 infections with whipworms (Trichuris trichiura), 900,000,000 infections with hookworm (Ancylostoma duodenale and Necator americanus), 657,000,000 infections with filarial worms, 200,000,000 with blood flukes (schistosome species), and 489,000,000 infections with malaria. These infections cause between 1,590,000 to 3,130,000 …

Coprolite Analysis: The Analysis Of Ancient Human Feces For Dietary Data, Karl Reinhard

Karl Reinhard Publications

Although archaeological fieldwork is hot and dirty, the most “earthy” side of the discipline is the laboratory analysis of coprolites. Each coprolite contains the remains of one to several actual meals eaten in prehistory, and analysis of many coprolites provides a picture of ancient diet that is unique in accuracy.

The term coprolite originally referred to fossilized feces in paleontological context. In archaeology, the term broadened to refer to any formed fecal mass, including mineralized, desiccated, or frozen feces and even the intestinal contents of mummies. Coprolites contain the remains of animals (parasites) that lived in the humans, the foods …

Paleopharmacology, Karl Reinhard

Karl Reinhard Publications

An emerging field devoted to the exploration of the archaeological record for evidence of medicinal plants.

In the future, archaeology will have a role in pharmaceutical research. In the late twentieth century, much of the world’s pharmaceutical research has been based on ethnographic documentation of tribally recognized medicinal plants. Once the active chemical compounds in the plants are identified, they are either extracted or synthesized for commercial use. The American film Medicine Man depicts this approach. As shown in the film, such pharmacological research is threatened by declining tribal populations with loss of traditional herbal knowledge coupled with declining biodiversity. …

The Systematics Of The Genus Trichinella With A Key To Species, K. D. Murrell, J. Ralph Lichtenfels, Dante S. Zarlenga, E. Pozio

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The authors review the major biological, biochemical, and molecular characters that are used to distinguish the seven Trichinella species (T. spiralis, T. nativa, T. britovi, T. pseudospiralis, T. murrelli, T. nelsoni, T. papuae) and three genotypes whose taxonomic status is yet uncertain (T-6, T-8, T-9). A comparison of host specificity, morphology, reproductive abilities, nurse cell development and freeze resistance is presented, along with useful biochemical and molecular markers. Finally, this information is used to construct a diagnostic key for the species. A phylogenetic classification of the species is needed.

Hazing And Movements Of Canada Geese Near Elmendorf Air Force Base In Anchorage, Alaska, Darryl L. York, John L. Cummings, Richard M. Engeman, Kate L. Wedemeyer

United States Department of Agriculture Wildlife Services: Staff Publications

Bird strikes to aircraft are a serious economic and safety problem in the United States, annually causing millions of dollars in damage to civilian and military aircraft and the occasional loss of human life. We observed movements of 1236 neckbanded lesser Canada geese (Branta canadensis parvipes) to determine efficacy of hazing as a means to reduce goose presence at Elmendorf Air Force Base (EAFB), Anchorage, Alaska from August to October 1997. Emphasis was on movements of geese onto EAFB with additional data collected at the other two major airports in the area, Anchorage International Airport (AIA) and Merrill …
