Gonadotropin-releasing hormone analogue therapy for peritoneal inclusion cysts after gynecological surgery.

OBJECTIVE: The purpose of this report is to estimate the effectiveness of gonadotropin-releasing hormone analogue (Gn-RHa) therapy for peritoneal inclusion cysts. METHODS: Patients who had cystic masses that developed after gynecological surgery and were strongly suspected of being peritoneal inclusion cysts based on the results of ultrasound, magnetic resonance imaging (MRI), and tumor marker studies, were treated with a Gn-RHa (buserelin acetate or leuprorelin acetate). Buserelin acetate was administered at a dose of 900 microg/day, and leuprorelin acetate at a dose of 3.75 mg/month. Ultrasonography was performed in the outpatient clinic every 2 weeks after the start of administration to measure the diameter of cysts. RESULTS: We treated 8 patients with peritoneal inclusion cysts conservatively with a Gn-RHa. The cysts resolved in 7 of the patients. Two of them developed a recurrence, but further Gn-RHa therapy was followed by complete resolution of the cysts in one patient and we resume Gn-RHa therapy to the other patient. The peritoneal inclusion cysts failed to shrink in only one patient. CONCLUSION: It is suggested that Gn-RHa therapy is effective in some cases of peritoneal inclusion cysts.

Irregularly shaped inclusion cysts display increased expression of Ki67, Fas, Fas ligand, and procaspase-3 but relatively little active caspase-3.

Human ovarian cancers are thought to arise from sequestered ovarian surface epithelial (OSE) cells that line the wall of inclusion cysts. Nevertheless, the early events toward neoplasia are not well understood. In this study, immunoreactivity for apoptotic proteins in human OSE of control and tumor ovarian sections was examined. Ki67, a marker for cell proliferation, was generally absent in the flat-to-cuboidal OSE cells on the ovarian surface and in regularly shaped inclusion cysts. Fas, Fas ligand, and caspase-3, components of the apoptotic pathway, were also largely absent. Ki67, Fas, Fas ligand, and procaspase-3 expression, though not active caspase-3 expression, was more frequently observed in epithelial cells lining irregularly shaped inclusion cysts, particularly in the columnar and Müllerian-like OSE cell types that resembled ovarian tumor OSE cells. Immunoreactivity for these factors as well as active caspase-3 was found frequently in ovarian tumors. We postulate that the appearance of the Fas system and its related proteins in sequestered columnar OSE cells of irregularly shaped inclusion cysts may contribute to balance cell growth with cell death, although little active caspase-3 expression was observed. Further studies are required to identify whether inhibition of apoptosis in inclusion cysts is an early event in ovarian carcinogenesis.

Tau-positive glial inclusions in progressive supranuclear palsy, corticobasal degeneration and Pick's disease.

The presence of tau-positive glial inclusions has been recently found a consistent feature in the brains of patients with progressive supranuclear palsy (PSP), corticobasal degeneration (CBD) and Pick's disease (PiD). These inclusions are classified based on cellular origin as tau-positive astrocytes, presumably either fibrillary or protoplasmic, coiled bodies and glial threads. Immunohistochemically, their major structural component is abnormal tau proteins, similar to those found in Alzheimer's disease. Nevertheless, their morphology, including ultrastructural profile, has been suggested to be distinctive for each disease. The profile and extent of particular glial inclusions correlate well with disease phenotype. Highly characteristic correlations include tufts of abnormal fibers in PSP, astrocytic plaques and dense glial threads in CBD and ramified astrocytes and small Pick body-like inclusions in PiD. The significance of the inclusions in disease pathogenesis and their biochemical characteristics remain to be clarified. Nevertheless, these distinctive glial lesions most likely reflect fundamental alterations in isoform composition of tau as well as its specific cellular and regional expression in sporadic tauopathies.

Noncrystalline inclusions in erythrocytes of a rhinoceros iguana.

In the following case, intracytoplasmic and intranuclear noncrystalline inclusions are found in the erythrocytes of a male Rhinoceros Iguana. Ultrastructurally, cytoplasmic inclusions are hexagonal with sharp borders not bound by a membrane. Similar to surrounding hemoglobin in that they are amorphous, homogenous and composed of finely textured material, the inclusions are easily differentiated by their symmetry and weak electron density. Nuclear inclusions are observed causing margination of chromatin and nucleoplasm. They are also easily distinguished by their hexagonal shape, weak electron density and the greater granularity of the surrounding nucleoplasm. The case is unusual because noncrystalline inclusions other than Heinz bodies have not yet been described in the erythrocytes of animals with nucleated red cells.

A silicate inclusion in Puente del Zacate, a IIIA iron meteorite.

The IIIA and IIIB iron meteorites are considered to have formed in the cores of asteroids. A silicate inclusion within the IIIA meteorite Puente del Zacate consisting of olivine (Fa4), low-calcium pyroxene (Fs6Wo1), chromium diopside (Fs3Wo47), plagioclase (An14Or4), graphite, troilite, chromite, daubreelite, and iron metal resembles inclusions in IAB iron meteorites. The oxygen isotopic composition of the Puente del Zacate inclusion is like chromite and phosphate inclusions in other IIIA and IIIB irons. The Puente del Zacate inclusion may have been derived from the lower mantle of the IIIAB parent asteroid.

Composition and Toxicity of the Inclusion of Bacillus thuringiensis subsp. israelensis.

The multisegmented ovoidal inclusion of Bacillus thuringiensis subsp. israelensis was found to be composed of two structurally and biochemically distinct components. Electron microscopy of the inclusion revealed it to be composed mainly of osmiophobic or lightly stained segments crystallized in a lattice showing a repeat of approximately 4.3 nm. These light segments of the inclusions were shared by osmiophylic darkly stained segments with a crystal lattice repeat of approximately 7.8 nm. The lightly stained segments were soluble at pH 9.2 in sodium dodecyl sulfate-dithiothreitol-Tris-hydrochloride. The extracts of lightly stained segments were lytic to mammalian erythrocytes, and the precipitate obtained by lowering the pH to 5.2 was toxic to the larvae of Aedes egypti. The dark inclusion segments remaining, besides being much less toxic to larvae, were nonlytic to erythrocytes and were soluble at pH 10.5 in sodium dodecyl sulfate-dithiothreitol-Tris-hydrochloride. The light segment was composed of two major polypeptide doublets with molecular weights of 145,000 and 135,000, and 27,000 and 26,500, and the dark segments were composed of a single major polypeptide with a molecular-weight of 70,000. Hence, the inclusion of B. thuringiensis subsp. israelensis is more complex than previously reported, and we conclude that the toxin may be the polypeptide with a molecular weight of 27,000 and 26,500.

Localization of inclusion bodies in Escherichia coli overproducing beta-lactamase or alkaline phosphatase.

High-level synthesis of the periplasmic protein beta-lactamase in Escherichia coli caused the formation of insoluble protein precipitates called inclusion bodies. beta-Lactamase inclusion bodies differed from those reported previously in that they appeared to be localized in the periplasmic space, not in the cytoplasm. The inclusion bodies contained mature beta-lactamase and were solubilized more easily than has been reported for cytoplasmic inclusion bodies. In contrast, overproduction of the periplasmic protein alkaline phosphatase caused the formation of cytoplasmic inclusion bodies containing alkaline phosphatase precursor.

Mathematical model for determining the effects of intracytoplasmic inclusions on volume and density of microorganisms.

Procaryotic microorganisms accumulate several polymers in the form of intracellular inclusions as a strategy to increase survival in a changing environment. Such inclusions avoid osmotic pressure increases by tightly packaging certain macromolecules into the inclusion. In the present paper, a model describing changes in volume and density of the microbial cell as a function of the weight of the macromolecule forming the inclusion is derived from simple theoretical principles. The model is then tested by linear regression with experimental data from glycogen accumulation in Escherichia coli, poly-beta-hydroxybutyrate accumulation in Alcaligenes eutrophus, and sulfur accumulation in Chromatium spp. The model predicts a certain degree of hydration of the polymer in the inclusion and explains both the linear relationship between volume of the cell and weight of the polymer and the hyperbolic relationship between density of the cell and weight of the polymer. Other implications of the model are also discussed.

Isolation of a relatively nontoxic 65-kilodalton protein inclusion from the parasporal body of Bacillus thuringiensis subsp. israelensis.

Ultrastructural studies of the mosquitocidal bacterium Bacillus thuringiensis subsp. israelensis revealed that the parasporal body contained three major inclusion types, designated types 1, 2, and 3, which could be differentiated on the basis of electron opacity and size and, to some extent, shape. The type-2 inclusion, which was of moderate electron density and often appeared as a bar-shaped polyhedral body, was isolated on NaBr gradients from purified parasporal bodies and characterized by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, transmission electron microscopy, and bioassays against neonate larvae of Aedes aegypti. Purified inclusions averaged 150 to 200 nm by 500 to 700 nm in transverse sections and consisted almost exclusively of a 65-kilodalton (kDa) protein contaminated with minor quantities of 38- and 28-kDa proteins. Lethal concentration values at the 50% level for preparations of the purified parasporal body and the type-2 inclusion were, respectively, 0.66 and 43 ng/ml, indicating that the 65-kDa protein is only slightly toxic to mosquitoes in comparison to the intact parasporal body. Analysis of the type-2 polyhedral inclusion by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and bioassays during different stages of purification demonstrated a positive correlation between the toxicity of the preparation and the degree of contamination with the 28-kDa protein. These results indicate that the 65-kDa protein is not the primary larvicidal toxin, although it may act in conjunction with other parasporal body proteins to produce the high mosquitocidal toxicity characteristic of this bacterium.

Detection of chlamydial inclusions in cell culture or biopsy tissue by alkaline phosphatase-anti-alkaline phosphatase staining.

An immunological technique for detecting Chlamydia trachomatis and Chlamydia psittaci inclusions in infected McCoy cell cultures was developed by using a genus-specific monoclonal antibody to Chlamydia spp., rabbit anti-mouse immunoglobulin G bridging antibody, alkaline phosphatase-anti-alkaline phosphatase (APAAP) monoclonal antibody conjugate, and naphthol AS-phosphate/fast red substrate. Chlamydial inclusions stained red and were easily detected against a background of blue hematoxylin-stained nuclei. After 18 h, inclusions of C. trachomatis serovar L2 LGV434/Bu and C. psittaci strain 6BC were stained by APAAP but not by iodine or Giemsa. At 48 h inclusion counts were significantly higher in the APAAP cultures. Both the APAAP procedure and conventional staining detected 35 of 239 (15%) cultures 48 h after inoculation with urethral or endocervical specimens. However, at 24 h after inoculation 22 of 35 (63%) were positive by APAAP staining while negative by iodine. This immunostain also allowed identification of chlamydial inclusions in endometrial biopsies from patients with tubal factor infertility or pelvic inflammatory disease.

Pathology and Development of the Grasshopper Inclusion Body Virus in Melanoplus sanguinipes.

Grasshoppers, Melanoplus sanguinipes (F.), infected with the grasshopper inclusion body virus (GIBV) showed a general torpor, took longer to develop, and had abnormally high rates of mortality. Infection was found only in the fat body, and developing viruses and inclusion bodies were observed in the nuclei and cytoplasm of infected cells. Although the size of the inclusion bodies in cells varied at different stages of infection, the inclusion bodies appeared to grow during the infection. Electron microscopic investigations of viral replication showed that at about 8 days after inoculation presumptive viral particles had developed as buds or protrusions from precursor granular masses; thereafter, these particles underwent internal differentiation and were incorporated into developing inclusion bodies. The GIBV was similar to insect viruses in the genus Vagoiavirus Weiser and to pox viruses, particularly vaccinia.

A rapid method for staining inclusions of Chlamydia psittaci and Chlamydia trachomatis.

A new staining method was developed for the detection of inclusions of Chlamydia psittaci and Chlamydia trachomatis inclusions in cell cultures. Using a combination of methyl green and neutral red stains and washing at pH 5.0, inclusions were stained red while cell cytoplasm was pale pink and cell nuclei were pale green. The method was significantly better than Giemsa staining and comparable to immunofluorescence for detecting C psittaci inclusions. Its sensitivity for detection C trachomatis inclusions by dark field microscopy was similar to that of Giemsa staining.

Plasmids associated with a phagelike particle and with a satellite inclusion in Bacillus thuringiensis ssp. israelensis.

Variants of Bacillus thuringiensis ssp. israelensis were isolated using a 42 degrees C plasmid curing method. Those that were missing the large toxic crystalline inclusion still possessed in their sporulated cells a small inclusion similar to the satellite inclusion of the wild type. These crystal-minus but satellite-positive variants, like the wild type, produced sporulation-dependent phagelike particles; variants lacking both the crystal and the satellite did not. These latter strains lacked both a 75 and a 68 megadalton plasmid present in the wild type. However, a crystal-positive, satellite-minus strain possessing the 75 but lacking the 68 megadalton plasmid produced the phagelike particles. Examination of recipient strains that were initially devoid of crystal, satellite, and plasmids revealed the satellite and phagelike producing characteristics could have been cotransformed with the 68 megadalton plasmid. Likewise the toxic crystal and phagelike particle producing characters could have been cotransformed into a recipient which had acquired the 75 megadalton plasmids already known to be associated with the synthesis of the crystal inclusion. Thus the gene coding for the satellite inclusion appears to reside in the 68 megadalton plasmid, while that coding for the phagelike particle can reside in either the 68 or 75 megadalton plasmid.

Definition and yield of inclusion criteria for a meta-analysis of patient education studies in clinical preventive services.

Because selection of studies for a literature review influences conclusions, inclusion criteria are of utmost importance. For a meta-analysis of studies testing effects of patient education on preventive behaviors, we present the framework and concepts used for setting inclusion criteria for primary studies. We also present the yield in terms of number and distribution of studies that resulted from the inclusion criteria. Because we were interested in a diverse range of behaviors and a broad definition of patient education, we present a method for grouping behaviors by type of behavior change and describe parameters for subgrouping interventions by orientation and communication channel. Of 5,451 citations located and abstracts screened, 561 citations reporting potentially relevant studies were reviewed. Based on our inclusion criteria, 171 citations contained relevant studies, of which 64 studies (found in 62 citations) also met our acceptability criteria. We examine the effects of alternate inclusion criteria on the yield of primary studies and their distributions across the subgroupings.

Antipyretic, analgesic and anti-inflammatory activities of ketoprofen beta-cyclodextrin inclusion complexes in animals.

Ketoprofen is a nonsteroidal anti-inflammatory drug (NSAID) orally effective in treating fever, pain, and inflammation but gastrointestinal side effects were observed. Preparation of ketoprofen beta-cyclodextrin inclusion complexes was to increase the solubility and reduce the irritation. The complexes were prepared and preliminarily confirmed using X-ray diffraction and dissolution test. Antipyretic, analgesic and anti-inflammatory models were induced by 10% yeast using rabbits, 0.8% acetic acid using mice and 1% carrageenin using rats, respectively. Results showed that the dissolution rate of ketoprofen was significantly improved by complexation. X-Ray diffraction pattern of the complexes exhibited a diffuse pattern that differed from that of physical mixture of ketoprofen and beta-cyclodextrin. Ketoprofen markedly inhibited the fever reactions at a single dose of 2 mg/kg as follows: 64.53% (inhibition rate %) at 1 h for ketoprofen, 73.04% at 1 h for ketoprofen beta-cyclodextrin inclusion complexes, respectively. Alleviating pain reaction rates following a single dose of 8 mg/kg at 20 min were 39.25% for the inclusion complexes and 26.72% for ketoprofen, respectively. Inhibition rates to rat edema following a single dose of 5 mg/kg at 1 h were 39.47% for the inclusion complexes and 23.86% for ketoprofen. Results for antipyretic, analgesic and anti-inflammatory activities showed that the rapid and stronger effects were found in the treatment group of ketoprofen beta-cyclodextrin inclusion complexes in comparison with those of free ketoprofen.

Kinetic and thermodynamic analysis of the cyclodextrin-allyl isothiocyanate inclusion complex in an aqueous solution.

The decomposition of allyl isothiocyanate (AITC) in an aqueous solution was depressed in the presence of cyclodextrin (CD), it's suppression effect increasing in the order of none < beta-CD < alpha-CD. The results of kinetic and thermodynamic analysis of the CD-AITC inclusion complexes showed that the inclusion process was mostly governed by an enthalpy change (delta H degree) rather than by an entrophy change (delta S degree), and that Van der Waals forces played a primary role int he inclusion. Steric factors were important for the reaction activity of AITC inclusion into the CD cavity, especially significant being the stereospecificity between the size of the CD cavity and the AITC molecule which is the main factor concerning it's activity. Our results suggest that the association stability and activity of the included AITC molecule are important factors in the suppression mechanism for CDs. Therefore, both these factors would make an alpha-CD-AITC system more advantageous than a beta-CD-AITC system, and the marked suppression effect of alpha-CD on the decomposition of AITC can be attributed to the formation of inclusion complexes in an aqueous solution.

Attitudes on inclusion of a player with disabilities in a regular softball league.

Although attitudes of sports participants relate significantly to the successful inclusion of individuals with disabilities in regular sport programs, there has been no published research on attitudes toward inclusion or rule modifications. We examined attitudes of girls without disabilities, their parents, and their coaches towards inclusion of a child with disabilities in a regular girls' fast-pitch softball league. They completed the Attitudes Towards Integrated Sports Inventory prior to the season. Results suggest that players and parents had a favorable attitude towards inclusion and towards modifying the game rules to enable this player to have a safe, successful experience. Coaches were undecided about inclusion and rule modifications.
