Fusion Activity And Inactivation Of Influenza Virus: Kinetics Of Low Ph-Induced Fusion With Cultured Cells, Nejat Düzgüneş, Maria C. Pedroso De Lima, L. Stamatatos, D. Flasher, D. R. Alford, Daniel S. Friend, S. Nir Jan 1992

Fusion Activity And Inactivation Of Influenza Virus: Kinetics Of Low Ph-Induced Fusion With Cultured Cells, Nejat Düzgüneş, Maria C. Pedroso De Lima, L. Stamatatos, D. Flasher, D. R. Alford, Daniel S. Friend, S. Nir

All Dugoni School of Dentistry Faculty Articles

The kinetics of fusion of influenza virus (A/PR/8/34) with human promyelocytic leukaemia (HL-60), human T lymphocytic leukaemia (CEM) and murine lymphoma (S49) cells were investigated. Fusion was demonstrated by electron microscopy, and monitored by fluorescence dequenching of octadecylrhodamine incorporated in the virus membrane. Rapid fusion was induced upon mild acidification of the medium. At pH 5, all virus particles were capable of fusing with the cells. The initial rate and the extent of fusion were maximal between pH 4.9 and 5.2 and declined sharply below and above this range. The rate constants of adhesion of influenza virus to cells or …


Altered Expression Of Adenovirus 12 Dna-Binding Protein But Not Dna Polymerase During Abortive Infection Of Hamster Cells, Lynne A. Lucher, Benjawan Khuntirat, Jiansheng Zhao, Peter C. Angeletti Jan 1992

Altered Expression Of Adenovirus 12 Dna-Binding Protein But Not Dna Polymerase During Abortive Infection Of Hamster Cells, Lynne A. Lucher, Benjawan Khuntirat, Jiansheng Zhao, Peter C. Angeletti

Nebraska Center for Virology: Faculty Publications

Replication of human adenovirus type 12 DNA is blocked in abortively infected baby hamster kidney cells. The activity and accumulation of adenovirus 12 DNA polymerase is equivalent in infected hamster and human cell extracts. However, the accumulation of adenovirus type 12 DNA-binding protein is approximately 120-fold lower in extracts from infected hamster cells when compared to infected permissive human cells. This difference in accumulation is not because of replication of viral DNA during productive infection, since this difference is observed in the presence of hydroxyurea. The DNA-binding protein from infected hamster cells retains the ability to bind denatured DNA-cellulose. An …


Improved Recovery Of A Radlolabeled Peptide With An Albumin-Treated Reversed-Phase Hplc Column, David S. Hage, Robert L. Taylor, Pai C. Kao Jan 1992

Improved Recovery Of A Radlolabeled Peptide With An Albumin-Treated Reversed-Phase Hplc Column, David S. Hage, Robert L. Taylor, Pai C. Kao

David Hage Publications

Reversed-phase high-performance liquid chromatography (RP-HPLC) is an important tool in the purification of radiolabeled peptides and proteins for immunoassay. However, for some proteins and peptides it is difficult to achieve reproducible behavior in RP-HPLC because of the low recovery of these compounds. Factors that can be varied to improve recovery include the strength or pH of the mobile phase, the chain length and spacing of groups on the reversed-phase support, and the flow rate or steepness of the elution gradient (1-5). ... In summary, we obtained better recovery and more reproducible chromatographic behavior for labeled 1-34 PTHrP with an albumin-pretreated …


Intact Parathyroid Hormone: Performance And Clinical Utility Of An Automated Assay Based On High-Performance Immunoaffinity Chromatography And Chemiluminescence Detection, David S. Hage, Bob Taylor, Pai C. Kao Jan 1992

Intact Parathyroid Hormone: Performance And Clinical Utility Of An Automated Assay Based On High-Performance Immunoaffinity Chromatography And Chemiluminescence Detection, David S. Hage, Bob Taylor, Pai C. Kao

David Hage Publications

The performance and clinical utility of an automated assay of intact parathyroid hormone (parathyrin, PTH) are evaluated. The method is based on the extraction of PTH from plasma by an HPLC column containing immobilized anti-(44-68 PTH) antibodies. The PTH retained is detected with a postcolumn reactor and use of anti-(1--34 PTH) chemiluminescent-labeled antibodies. The total cycle time of the assay is 6.5 mm per injection after a 1-h incubation.The lower limit of detection for PTH in a 66-pL plasma sample was 0.5 pmol/L based on peak heights and 0.2 pmol/L based on peak areas. Mean analytical recovery for PTH added …


Coprolite Analysis: A Biological Perspective On Archaeology, Karl J. Reinhard, Baughn M. Bryant Jr Jan 1992

Coprolite Analysis: A Biological Perspective On Archaeology, Karl J. Reinhard, Baughn M. Bryant Jr

Karl Reinhard Publications

The most remarkable dietary remains recoverable from archaeological contexts are coprolites. Coprolites are desiccated or mineralized feces that are preserved in sheltered and open sites in arid regions, primarily in the New World. These dietary remains are remarkable from several perspectives. They typically contain a variety of macroscopic and microscopic remains that form interrelated data sets for the reconstruction of diets. Because contexts containing coprolites are typified by excellent preservation, the remains coprolites contain tend to be in better states of preservation than dietary remains recovered from nonfecal deposits. Coprolites also contain the well-preserved remains of intestinal parasites and pathogens …


Vertebral Pathology In Prehistoric And Historic Skeletons From Northeastern Nebraska, Karin L. Sandness, Karl J. Reinhard Jan 1992

Vertebral Pathology In Prehistoric And Historic Skeletons From Northeastern Nebraska, Karin L. Sandness, Karl J. Reinhard

Karl Reinhard Publications

Vertebral pathology has long been a useful criterion for anthropologists in the assessment of activity patterns, stress, and general health of extinct peoples. This method of analysis, however, has never been applied to the peoples of the Nebraska Great Plains. This study is the first to concentrate on the indigenous Native Americans of this region, examining the spinal pathology present in the prehistoric and historic skeletal remains. Pathology present in the form of spondylolysis, Schmorl's nodes, osteophytosis (degenerative disc disease), and osteoarthritis (degenerative joint disease), provides evidence to suggest differing activity patterns and levels of stress in Plains groups before …


Dan Canyon Burial: A Piii Burial In Glen Canyon National Recreation Area, Steve Dominguez, Karl Reinhard, Kari L. Sandness, Cherie A. Edwards, Dennis Danielson, F. A. Calabrese, Chris Kincaid Jan 1992

Dan Canyon Burial: A Piii Burial In Glen Canyon National Recreation Area, Steve Dominguez, Karl Reinhard, Kari L. Sandness, Cherie A. Edwards, Dennis Danielson, F. A. Calabrese, Chris Kincaid

Karl Reinhard Publications

The Dan Canyon burial was discovered at a time when the philosophy, ethics, and legislation concerning the study of human remains are in a state of flux. A number of important sensitive issues germane to managers, archeologists, and American Indians are discussed in the introduction. The subsequent analysis provides a detailed scientific account of these remains and a glimpse of a segment of a people's past lifeway while remaining sensitive to the wishes of the American Indians.

The burial and associated grave goods of site 42SA21339 were exposed by wave action in a location frequented by boaters at the Glen …


The Ear’S Versus The Eye’S Potential To Assess Characteristics Of Numeric Data: Are We Too Visuocentric?, John H. Flowers, Terry A. Hauer Jan 1992

The Ear’S Versus The Eye’S Potential To Assess Characteristics Of Numeric Data: Are We Too Visuocentric?, John H. Flowers, Terry A. Hauer

Department of Psychology: Faculty Publications

A single experiment studied how effectively information about the central tendency, variability, and shape of numeric data distributions could be conveyed to statistically knowledgeable subjects. The data were summarized by visual histograms, auditory histograms that coded numeric value as pitch on the musical scale, and five-note auditory analogues of a box-whisker display that coded the minimum, quartile, and maximum scores as musical notes. Regression and multidimensional scaling analysis of judgments of dissimilarity between distributions showed that auditory depiction provides a highly effective means of conveying information about distributional characteristics. Auditory depicition may be a useful alternative to traditional visual graphics.


Assessing Stress In Teachers: Depressive Symptoms Scales And Neutral Self-Reports Of The Work Environment, Irvin Sam Schonfeld Jan 1992

Assessing Stress In Teachers: Depressive Symptoms Scales And Neutral Self-Reports Of The Work Environment, Irvin Sam Schonfeld

Publications and Research

The focal interest of this chapter on teacher stress is methodologic. The chapter enumerates a number of defects in existing measures of job stress in teachers and, concomitantly, other helping professionals. Alternative ways of measuring stress in teachers are suggested and evaluated. The use of depressive symptom scales in concert with more 'objective' measures of the work environment is discussed. An application of the proposed alternative measurement strategy is described. The wider utility of the measurement strategy is briefly described.

Multiple Alleles And Estimation Of Genetic Parameters: Computational Equations Showing Involvement Of All Alleles, R Chakraborty Jan 1992

Multiple Alleles And Estimation Of Genetic Parameters: Computational Equations Showing Involvement Of All Alleles, R Chakraborty

Faculty, Staff and Student Publications

Extracellular vesicles (EVs), through their complex cargo, can reflect the state of their cell of origin and change the functions and phenotypes of other cells. These features indicate strong biomarker and therapeutic potential and have generated broad interest, as evidenced by the steady year‐on‐year increase in the numbers of scientific publications about EVs. Important advances have been made in EV metrology and in understanding and applying EV biology. However, hurdles remain to realising the potential of EVs in domains ranging from basic biology to clinical applications due to challenges in EV nomenclature, separation from non‐vesicular extracellular particles, characterisation and functional …


Recombinant Kinetoplast Dna (Kdna) Probe For Identifying Leishmania Tropica, N. N. Massamba, M. J. Mutinga Jan 1992

Recombinant Kinetoplast Dna (Kdna) Probe For Identifying Leishmania Tropica, N. N. Massamba, M. J. Mutinga

All Peer-Reviewed Publications

The paper reports on the construction of a kDNA library with DNA isolated from the WHO reference strain of Leishmania tropica IC-305 and subsequent identification and propagation of recombinant plasmids containing L. tropica kDNA sequences. It also shows that the cloned kDNA sequences can be used as genetic markers in restriction endonuclease, Southern blot transfer, and dot blot hybridisation analysis, to identify L. tropica parasites. When the pL 305-I kDNA probe was used in hybridisation experiments with DNAs from various Leishmania reference strains, species and isolates from different host species and from different geographical locations, hybridisation was detected only with …


Prevalence Of Iron Deficiency Anaemia In Children Of The Urban Slums Of Karachi, Ayesha Molla, Mohammad Khurshid, A. Majid Molla Jan 1992

Prevalence Of Iron Deficiency Anaemia In Children Of The Urban Slums Of Karachi, Ayesha Molla, Mohammad Khurshid, A. Majid Molla

Department of Pathology and Laboratory Medicine

A preliminary baseline survey was conducted to estimate the prevalence of anaemia in a group of 391 children aged 6-60 months, randomly selected from three urban slums of Karachi. Haemoglobin and the red cell indices including haematocrit, MCV, MCH, MCHC, ABC and red cell distribution width (RDW) were estimated for each of the selected children. Ferritin estimation was done on 354 (9 1%) children to assess the iron storage status. According to WHO criteria, the accepted cut-off point for anaemia screening in children is set at 11 gm/dl, 70 fI and 20 pg for haemoglobin, MCV and MCH respectively. Following …


Radiation Induced Tumor Lysis Syndrome In Patients With Leukemia, Imtiaz A. Malik, Paul Vellozo, Mohammad Khurshid, M. Ata Khan Jan 1992

Radiation Induced Tumor Lysis Syndrome In Patients With Leukemia, Imtiaz A. Malik, Paul Vellozo, Mohammad Khurshid, M. Ata Khan

Department of Medicine

Tumour lysis syndrome is a catastrophic complica­lion of treatment of certain neoplasms. It is usually seen with the tumours that have high growth fractions, increased bulk and extreme sensitivity to cytotoxic therapy. Most commonly it occurs in association with hematologic malignancies such as lymphomas and leukaemias. Rarely it has been observed with solid tumours like small cell lung cancer, seminoma and carcinoma of the breast. The syndrome develops due to massive cell lysis occurring within a few hours to a few days of starting the cytotoxic therapy. It is characterized by hyperuricemia, hyperkalemia, hyperphosphatemia and hypocalcaemia. Acute renal failure, cardiac …

First Evidence Of Plague (Yersinia Pestis) In Nebraska Is Found In Panhandle Predators, Dallas Virchow, Wayne L. Kramer, Charles S. Brown, Scott E. Hygnstrom, Alan M. Barnes Jan 1992

First Evidence Of Plague (Yersinia Pestis) In Nebraska Is Found In Panhandle Predators, Dallas Virchow, Wayne L. Kramer, Charles S. Brown, Scott E. Hygnstrom, Alan M. Barnes

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

In September, 1992, plague (Yersinia pestis) antibody was found in the blood of a coyote (Canis latrans) (1:128 titer) and a badger (Taxidea taxus) (1:2048 titer) taken near a suspect black-tailed prairie dog (Cynomys ludovicianus) town in Sioux County. However, a 1989-1991 survey of 96 coyotes taken from nine Nebraska Panhandle counties demonstrated no plague antibodies. Passive hemagglutination tests of Nobuto blood-sampling paper proved useful to quickly survey a predator population that is distributed across a broad geographic area.


Glottal Airflow And Electroglottographic Measures Of Vocal Function At Multiple Intensities, Christopher Dromey, Elaine T. Stathopouloss, Christine M. Sapienza Jan 1992

Glottal Airflow And Electroglottographic Measures Of Vocal Function At Multiple Intensities, Christopher Dromey, Elaine T. Stathopouloss, Christine M. Sapienza

Faculty Publications

Summary: Ten normal female subjects produced syllables at 5 dB increments from soft to loud. The differentiated electroglottogram (dEGG) open and speed quotients were compared to similar quotients from the inverse-filtered airflow waveform. The latter were measured according to objective and subjective criteria. The data indicate that the open quotient from the airflow waveform decreased as the intensity increased. The dEGG open quotient did not demonstrate this trend. The speed quotient from airflow increased initially with vocal intensity and decreased again as the intensity ceiling was approached. The ratio of closing to opening slopes calculated from peaks in the dEGG …

Studies On Tsetse Midgut Factors That Induce Differentiation Of Bloodstream Trypanosoma Brucei Brucei In Vitro, M. O. Imbuga, E. O. Osir, V. L. Labongo, N. Darji, L. H. Otieno Jan 1992

Studies On Tsetse Midgut Factors That Induce Differentiation Of Bloodstream Trypanosoma Brucei Brucei In Vitro, M. O. Imbuga, E. O. Osir, V. L. Labongo, N. Darji, L. H. Otieno

All Peer-Reviewed Publications

An in vitro system for studying the transformation of bloodstream forms of Trypanosoma brucei brucei into procylic (midgut) forms is described. In this system, transformation of the parasites was stimulated by Glossina morsitans morsitans midgut homogenates at 27° C but not at 4° C. The transformation-stimulating capacity was irreversibly destroyed by heating the midgut homogenates at 60° C for 1 h. A correlation was established between the transformation activity of the midgut homogenates and trypsin activity. The protease inhibitors (soybean trypsin inhibitor and N-p-tosyl-l-lysine-chloromethyl-ketone) inhibited trypsin activity and completely blocked the transformation of the parasites. Furthermore, the midgut homogenates could …


Trypanosome Infection Rates In Tsetse Flies (Diptera: Glossinidae) And Cattle During Tsetse Control Operations In The Kagera River Region Of Rwanda, Steve Mihok, Leonard H. Otieno, Christopher S. Tarimo Jan 1992

Trypanosome Infection Rates In Tsetse Flies (Diptera: Glossinidae) And Cattle During Tsetse Control Operations In The Kagera River Region Of Rwanda, Steve Mihok, Leonard H. Otieno, Christopher S. Tarimo

All Peer-Reviewed Publications

Trypanosome infections were monitored in three species of tsetse fly (Glossina pallidipes Austen, G. morsitans centralis Machado, and G. brevipalpis News-tead) at four locations in the Kagera River region of Rwanda from May 1989 to September 1990. Two of the four areas (Mpanga Ranch and Bukora Ranch) were subjected to tsetse fly suppression operations with odour-baited traps. Proboscis infections of the Trypanosoma congolense and T. vivax types accounted for roughly equal numbers of the 207 mature infections detected (3.8%). Variation in infection rates was area-specific rather than tsetse species-specific. Order of magnitude differences in tsetse fly densities among areas were …


Influence Of D(+)-Glucosamine On Infection Rates And Parasite Loads In Tsetse Flies (Glossina Spp.) Infected With Trypanosoma Brucei, Steve Mihok, Leonard H. Otieno, Nafisa Darji, David Munyinyi Jan 1992

Influence Of D(+)-Glucosamine On Infection Rates And Parasite Loads In Tsetse Flies (Glossina Spp.) Infected With Trypanosoma Brucei, Steve Mihok, Leonard H. Otieno, Nafisa Darji, David Munyinyi

All Peer-Reviewed Publications

Teneral Glossina morsitans centralis, G. m. morsitans and G. pallidipes were infected with three different clones of Trypanosoma brucei in blood containing d(+)-glucosamine, an inhibitor of tsetse midgut lectin. On average, 5 days of d(+)-glucosamine treatment tripled infection rates, without affecting the proportion of infections that matured. Total infection rates were equal in males and females, but twice as many infections matured in males. Counts of parasites in the guts and salivary glands of 277 flies revealed order of magnitude differences among flies, with females consistently having 2-3-times as many parasites as males. Parasite numbers varied in a sex-specific manner …


Laboratory And Field Observations On Anti-Tick Properties Of The Plant Gynandropsis Gynandra (L.) Brig, M. M. Malonza, O. O. Dipeolu, A. O. Amoo, S. M. Hassan Jan 1992

Laboratory And Field Observations On Anti-Tick Properties Of The Plant Gynandropsis Gynandra (L.) Brig, M. M. Malonza, O. O. Dipeolu, A. O. Amoo, S. M. Hassan

All Peer-Reviewed Publications

A shrubby plant, abundant in east Kenya, Gynandropsis gynandra (L.) Brig., was shown to exhibit repellent and acaricidal properties to larvae, nymphs and adult Rhipicephalus appendiculatus and Amblyomma variegatum ticks. All stages of ticks avoided the leaves of the plant and a high percentage of the ticks which were continuously exposed to its leaves died; surviving ticks were weak and inactive but regained activity when exposed to fresh air. The effectiveness of the plant's leaves as a repellent and acaricide was most pronounced on nymphs and least pronounced on adults. Field investigations indicated that ticks were not found up to …

Evidence For Proximal Control Of Ligand Specificity In Hemeproteins: Absorption And Raman Studies Of Cryogenically Trapped Photoproducts Of Ligand Bound Myoglobins, Mark R. Chance Dec 1991

Evidence For Proximal Control Of Ligand Specificity In Hemeproteins: Absorption And Raman Studies Of Cryogenically Trapped Photoproducts Of Ligand Bound Myoglobins, Mark R. Chance

Faculty Scholarship

The absorption and resonance Raman spectra of cryogenically trapped photoproducts of oxy and carboxy derivatives of myoglobin (Mb) are compared and analyzed in an attempt to understand the structural basis for ligand specificity in hemeproteins. Pulsed and cw excitations over a wide temperature range are used in order to differentiate between kinetic hole burning (KHB), optical pumping of structural relaxation, and spontaneous relaxation effects. Using these techniques, we are able to correlate changes in the absorption spectrum (band III at ≈ 760 nm) with low-frequency Raman bands. Based on these correlations we are able to determine which proximal heme pocket …
