The Eosinophil and Lysophospholipase Responses in Mice Infected with Trichinella spiralis: A Role for the Lymphocyte and Macrophage

The Eosinophil and Lysophospholipase Responses in Mice Infected with Trichinella spiralis: A Role for the Lymphocyte and Macrophage

Date: August 1986
Creator: Adewusi, Iyabode Olukemi, 1958-
Description: The relationship among eosinophils, lysophospholipase activity and the immune response in animals infected with Trichinella spiralis was studied using in vivo and in vitro techniques. In an in vivo experiment, anti-thymocyte serum (ATS) was administered to mice infected with T. spiralis and its effects on intestinal lysophospholipase (EC 3.1.1.5.) activity, peripheral blood, bone marrow and intestinal eosinophilia were measured in the same experimental animal. The ATS caused a significant temporally related suppression of both the tissue lysophospholipase response and eosinophilia, in all three compartments. These findings support the hypothesis that parasite-induced eosinophilia is the cause of the increased lysophospholipase activity of parasitized tissue and that the responses are thymus cell-dependent. In vitro experiments demonstrated that the eosinophil was the primary inflammatory cell source of lysophospholipase among eosinophils, neutrophils macrophages and lymphocytes. The role of other cells and antigen in the production of the enzyme by the eosinophil was also investigated in vitro• Results demonstrated that eosinophils cultured with both T. spiralis antigen and other leukocytes yielded enzyme activities significantly greater than eosinophils cultured alone or with only antigen. More specific experiments showed that T-lymphocytes were the cells responsible for influencing the eosinophils' lysophospholipase activity in the presence of antigen, and ...

The Eosinophil Response in Mice Infected with Trichinella spiralis or Trichinella pseudospiralis as Indicated by Phospholipase B Activity

The Eosinophil Response in Mice Infected with Trichinella spiralis or Trichinella pseudospiralis as Indicated by Phospholipase B Activity

Date: December 1992
Creator: Hsu, Shing-Chien
Description: The host eosinophil response was compared in mice infected with either T. spiralis or T. pseudospiralis by determination of levels of splenic and intestinal phospholipase B, a marker enzyme for eosinophils. Primary infection of naive mice and challenge infection of homologously sensitized mice with T. pseudospiralis resulted in significantly lower tissue phospholipase B activities than infection with T. spiralis. Mice homologously challenged with T. pseudospiralis did exhibit an anamnestic eosinophil response compared to mice given a primary T. pseudospiralis infection. This anamnestic response, however, was significantly lower than the eosinophil response seen in sensitized mice given a homologous T. spiralis challenge. Mice sensitized to T. spiralis or T. pseudospiralis and heterologous challenge demonstrated an elevated eosinophil response compared to mice given a primary infection with either parasite. The heterologous challenge response, however, was not as intense as found for sensitized mice given a homologous challenge.

The Epic Element in Hiawatha

The Epic Element in Hiawatha

Date: August 1953
Creator: Bass, Mary Laura
Description: By tracing the development of the epic, oral and written, as in Chapter III, the qualities that are characteristic of the epic and the devices associated with the epic through continued usage were found to be the constant factors upon which the definition of the epic is formulated. The application to Hiawatha of the epic definition in terms of form, theme, subject matter, characters, tone, the use of the supernatural, and the use of characteristic devices, strengthens the thesis that Longfellow has written an epic.

Epic Qualities in Moby-Dick

Epic Qualities in Moby-Dick

Date: August 1952
Creator: Russell, John Joe
Description: Many critics not satisfied with explaining Moby-Dick in terms of the novel, have sough analogies in other literary genres. Most often parallels have been drawn from epic and dramatic literature. Critics have called Moby-Dick either an epic or a tragedy. After examining the evidence presented by both schools of thought, after establishing a workable definition of the epic and listing the most common epic devices, and after examining Moby-Dick in terms of this definition and discovering many of the epic devices in it, I propose the thesis that Melville has written an epic, not unlike the great epics of the past.

Epidemiological Evaluation of Pain Among String Instrumentalists

Epidemiological Evaluation of Pain Among String Instrumentalists

Date: May 2011
Creator: Meidell, Katrin Liza
Description: Pain and performance anxiety (PA) are common problems among string players. Therefore, the purpose of this study was to assess and compare PA and prevalence rates and locations of pain in violinists, violists, cellists, and bassists. Subjects completed a questionnaire that included sections on demographics, musical background, practice habits, musculoskeletal problems, non-musculoskeletal problems, and PA. Anthropometric data were gathered on all 115 subjects. Results show that there are differences in both pain and PA across instrument groups. Violinists reported the highest number of pain sites, followed by violists, bassists, and cellists. The left shoulder was the most-often reported pain site, followed by the neck and right shoulder. Aching was the most cited term selected to describe pain. Several anthropometric indices were significantly correlated with pain, notably right thumb to index finger span in both cellists and bassists. In all instrument groups, at least one pain site was significantly correlated with one of four PA questions. Results warrant the development of intervention strategies and further study of the relationship between pain and performance anxiety.

Epoch Stages of Consciousness in The Rainbow

Epoch Stages of Consciousness in The Rainbow

Date: May 1978
Creator: Bardas, Mary Louise Ivey
Description: In The Rainbow D. H. Lawrence departs from traditional literary techniques, going below the level of ego consciousness within his characters to focus on the elemental dynamic forces of their unconscious minds. Using three generations of the Brangwen family, Lawrence traces the rise of consciousness from the primal unity of the uroboros through the matriarchal epoch and finally to full consciousness, the realization of the self, in Ursula Brangwen. By correlating the archetypal symbols characteristic of three stages of consciousness outlined in Erich Neumann's Origins and History of Consciousness and The Great Mother with the three sections of the novel, it is possible to show that Lawrence utilizes the symbols most appropriate to each stage.

Epoxy + Liquid Crystalline Epoxy Coreacted Networks

Epoxy + Liquid Crystalline Epoxy Coreacted Networks

Date: December 2000
Creator: Punchaipetch, Prakaipetch
Description: Molecular reinforcement through in-situ polymerization of liquid crystalline epoxies (LCEs) and a non-liquid crystalline epoxy has been investigated. Three LCEs: diglycidyl ether of 4,4'-dihydroxybiphenol (DGE-DHBP) and digylcidyl ether of 4-hydroxyphenyl-4"-hydroxybiphenyl-4'-carboxylate (DGE-HHC), were synthesized and blended with diglycidyl ether of bisphenol F (DGEBP-F) and subsequently cured with anhydride and amine curing agents. Curing kinetics were determined using differential scanning calorimetry (DSC). Parameters for autocatalytic curing kinetics of both pure monomers and blended systems were determined. The extent of cure for both monomers was monitored by using Fourier transform infrared spectroscopy (FT-IR). The glass transitions were evaluated as a function of composition using DSC and dynamic mechanical analysis (DMA). The results show that the LC constituent affects the curing kinetics of the epoxy resin and that the systems are highly miscible. The effects of molecular reinforcement of DGEBP-F by DGE-DHBP and DGE-HHC were investigated. The concentration of the liquid crystalline moiety affects mechanical properties. Tensile, impact and fracture toughness tests results are evaluated. Scanning electron microscopy of the fracture surfaces shows changes in failure mechanisms compared to the pure components. Results indicate that mechanical properties of the blended samples are improved already at low concentration by weight of the LCE added into ...

Equal Representation and State Legislative Apportionment: a Study of the Political Impact of the Legislative Reapportionment Decisions

Equal Representation and State Legislative Apportionment: a Study of the Political Impact of the Legislative Reapportionment Decisions

Date: January 1968
Creator: Clark, Robert B.
Description: This study is concerned with the political impact of the Supreme Court's decisions concerning state legislative apportionment. First, an attempt is made to describe the political environment in which they were made, with special reference to the existing bases of representation in the states and the political reaction to the decisions. Secondly, the study traces the major issues relating to judicial enforcement of the apportionment standards enunciated by the Supreme Court and the modification and development of those standards that followed the initial decisions. Finally, the extent to which reapportionment has been successfully enforced by the courts may suggest some tentative conclusions about the viability and utility of the equal population doctrine as a constitutional standard, as well as some of the possible political consequences of enforcement of that standard.
