    The bursa of Fabricius is critical for the normal development of B lymphocytes in birds. It is productively colonized during embryonic life by a limited number of B cell precursors that have undergone the immunoglobulin gene rearrangements required for expression of cell surface immunoglobulin. Immunoglobulin gene rearrangement occurs in the absence of terminal deoxynucleotidyl transferase and generates minimal antibody diversity. In addition, observations that immunoglobulin heavy and light chain variable gene rearrangement occur at the same time and that allelic exclusion of immunoglobulin expression is regulated at the level of variable region gene rearrangement provide a striking contrast to rodent and primate models of immunoglobulin gene assembly. Following productive colonization of the bursa, developing B cells undergo rapid proliferation and the immunoglobulin V region genes that generate the specificity of the B cell surface immunoglobulin receptor undergo diversification. Immunoglobulin diversity in birds is generated by somatic gene conversion events in which sequences derived from upstream families of pseudogenes replace homologous sequences in unique and functionally rearranged immunoglobulin heavy and light chain variable region genes. This mechanism is distinct from and much more efficient than mechanisms of antibody diversification seen in rodents and primates. While the bursal microenvironment is not required for immunoglobulin gene rearrangement and expression, it is essential for the generation of antibody diversity by gene conversion. Following hatch, gut derived antigens are taken up by the bursa. While bursal development prior to hatch occurs in the absence of exogenous antigen, chicken B cell development after hatch may therefore be influenced by the presence of environmental antigen. This review focuses on the differences between B cell development in the chicken as compared to rodent and primate models.

    Full Text Available Bursa Fabricius is a target organ of gumboro virus infection which is often damaged after vaccinationusing hot intermediate gumboro live vaccine. The purpose of this study was to assess pathologic effect oflocal and commercial gumboro vaccines . As many as 45 embryo chicken eggs at nine day old were used inthis research, then grouped into three groups of 15 embryos chicken eggs each, these were: Embryo chickeneggs without vaccination (Group I, vaccinated with IBD intermediate plus commercial vaccine (Group IIand IBD intermediate plus local vaccine (Group III. Vaccinations were done at 14 days old. All groups thenterminated each three embryos at 12 hours, 1, 2, 3 days post vaccination. The results showed that pathologicanatomic lesions could not be detected. Whereas pathologic lesions were detected in the group that werevaccinated with intermediate plus local IBD observed more severe than in the group that vaccinated withintermediate plus commercial IBD. Lesions such as edema, hemorrhages, necrosis of lymphoid cells wereobserved microscopically in embryo at 12 hours, 1, 2 and 3 days post vaccination in Group II and group III.The lesions were more severe at two days post vaccination causing some lymphoid follicles disappeared at three days post vaccination. However, they were not detected again in the bursa Fabricius three days afterhatching. Cells containing antigens of gumboro were detected in the bursa Fabricius of chicken embryo atone day until three days post vaccination, then disappeared after three days post hatch. It was concludedthat pathologic description of bursa fabricius showed that virus vaccines used for vaccinated IBD in ovowere still virulent, that can cause histopathologic lesions. The viruses are suggested to be more attenuatedbefore using as vaccine in ovo.

    Full Text Available During the past few years, there has been considerable interest on the effects of stocking density on broiler behavior and immunity. Stress may cause immunodeficiency by affecting cell and humoral responses, as well as body weight decrease, and foot-pad dermatitis. The aim of this study was to study histomorphological changes of the bursa of Fabricius in broilers submitted to three different stocking densities (10, 15, and 20 birds/m² from one to 42 days of age. Three birds from each group were sacrifieced on days 7 and 42. The bursa was collected, fixed, and processed for histomorphometric assessment using a Kontrom KS 400 image analyzer. Data were analyzed by Biostat 3.0 (Tukey Test. The results of average cortical area percentage in bursal follicles of 6-week-old birds were 45.12a (10 birds/m², 30.43b (15 birds/m², and 23.77b (20 birds/m². Average body weight was 2.58a kg (10 birds/m², 2.56a Kg (15 birds/m², and 2.47b Kg (20 birds/m², respectively. The percentage of foot-pad dermatitis in 6-week-old birds was 3.33a (10 birds/m², 17.76b (15 birds/m², and 49.17c (20 birds/m². These differences were statistically significant at a P<0.05 level. Under these experimental conditions,, it was concluded that the best stocking density to produce broilers is between 10-15 birds per square meter.

    The transcriptional effects of deregulated myc gene overexpression are implicated in tumorigenesis in a spectrum of experimental and naturally occurring neoplasms. In follicles of the chicken bursa of Fabricius, myc induction of B-cell neoplasia requires a target cell population present during early bursal development and progresses through preneoplastic transformed follicles to metastatic lymphomas. We developed a chicken immune system cDNA microarray to analyze broad changes in gene expression that occur during normal embryonic B-cell development and during myc-induced neoplastic transformation in the bursa. The number of mRNAs showing at least 3-fold change was greater during myc-induced lymphomagenesis than during normal development, and hierarchical cluster analysis of expression patterns revealed that levels of several hundred mRNAs varied in concert with levels of myc overexpression. A set of 41 mRNAs were most consistently elevated in myc-overexpressing preneoplastic and neoplastic cells, most involved in processes thought to be subject to regulation by Myc. The mRNAs for another cluster of genes were overexpressed in neoplasia independent of myc expression level, including a small subset with the expression signature of embryonic bursal lymphocytes. Overexpression of myc, and some of the genes overexpressed with myc, may be important for generation of preneoplastic transformed follicles. However, expression profiles of late metastatic tumors showed a large variation in concert with myc expression levels, and some showed minimal myc overexpression. Therefore, high-level myc overexpression may be more important in the early induction of these lymphomas than in maintenance of late-stage metastases. PMID:11353853

  9. Influence of Pasteurella multocida and high and low environmental temperatures on adrenals and bursa of Fabricius in turkeys

    The morphologic changes in the adrenals and bursa of Fabricius were evaluated from turkeys inoculated with Pasteurella multocida either in the palatine air spaces or via drinking water and maintained at high (33.4-37.4 C), low (2.6-5.3 C), and moderate (19.8-22.4 C) temperatures in temperature-controlled chambers. There was a slight hyperplasia of the adrenal cortical cells and a hypertrophy of the nuclei in the uninoculated turkeys maintained at both high and low temperatures, but these changes were more marked in turkeys maintained at low temperatures. Regardless of the temperature to which the turkeys were exposed, there was an increase in adrenal weight, hyperplasia of the cortical cells, hypertrophy of the nuclei of the cortical cells, and depletion of lipid in the cortical cells in the turkeys that became depressed after inoculation with P. multocida. In the uninoculated turkeys exposed to high temperatures there was a reduction in the weight of the bursa of Fabricius, atrophy of the follicles, and a reduction in the number of lymphocytes within the follicle, which did not occur in the bursae from uninoculated turkeys maintained at low temperatures. In the turkeys inoculated with P. multocida, there was a marked reduction in bursal weight, atrophy of the follicles, and reduction in the number of lymphocytes within the follicles.

    The mitotic index in the cortical compartment of the follicles of the bursa of Fabricius from chicks immunized with sheep red blood cells (SRBC) is always higher when compaired with non-immunized ones. This mitotic index reachs its maximum 6 days after the SRBC injection, coincident with the highest serum antibody titer. The mitotic activity in the cortex of the follicles of the bursa of Fabricius is always higher than that of the medulla during the postembryonic development of chickens (PROCHAZKA, RODAK, KREJCI 1967). Otherwise it is almost established that the cortex is a zone of continuous lymphocyte proliferation, not occuring the same with the medulla. In addition these bursal histological structures are considered as 2 distinct compartments (GROSSI et al. 1974). The purpose of this paper is to study the response in the mitotic index of the cortical and medullary compartments of the follicles of the bursa of immunized and non-immunized chicks. To correlate possible changes in the mitotic index with circulating antibody levels, the serum antibody titer from the same birds was also recorded.

    Concurrent fowlpox and candidiasis diseases occurred in a backyard chicken flock. Four deceased chickens (one Nagoya breed and three white silkie chickens) were examined for diagnosis. At necropsy, white curd-like plaques were observed in the crop. Fungal elements that stained positive for Candida albicans with immunohistochemistry were distributed throughout the tongue, choanal mucosa, esophagus, and crop. Typical fowlpox lesions, composed of proliferating epithelial cells with ballooning degeneration and viral intracytoplasmic inclusions, were observed in the conjunctiva, nasal mucosa, and skin around the cloaca. Interestingly, hyperplastic interfollicular epithelium with rare virus inclusions was observed in the bursa of Fabricius (BF). Some bursal follicles were replaced by proliferating epithelial cells. These proliferating cells immunohistochemically stained positive for cytokeratin. PCR and subsequent genetic sequencing detected the C. albicans gene in the crop, and fowlpox virus genes in the BF. These results indicate that this outbreak was a rare presentation of fowlpox in spontaneously infected chickens, with unusual pox lesions in the BF.

    Full Text Available Objective The bursa of Fabricius (BF is a central humoral immune organ belonging specifically to avians. Recent studies had suggested that miRNAs were active regulators involved in the immune processes. This study was to investigate the possible differences of the BF at miRNA level between two genetically disparate duck breeds. Methods Using Illumina next-generation sequencing, the miRNAs libraries of ducks were established. Results The results showed that there were 66 differentially expressed miRNAs and 28 novel miRNAs in bursa. A set of abundant miRNAs (i.e., let-7, miR-146a-5p, miR-21-5p, miR-17~92 which are involved in immunity and disease were detected and the predicted target genes of the novel miRNAs were associated with duck high anti-adversity ability. By gene ontology analysis and enriching KEGG pathway, the targets of differential expressed miRNAs were mainly involved in immunity and disease, supporting that there were differences in the BF immune functions between the two duck breeds. In addition, the metabolic pathway had the maximum enriched target genes and some enriched pathways that were related to cell cycle, protein synthesis, cell proliferation and apoptosis. It indicted that the difference of metabolism may be one of the reasons leading the immune difference between the BF of two duck breeds. Conclusion This data lists the main differences in the BF at miRNAs level between two genetically disparate duck breeds and lays a foundation to carry out molecular assisted breeding of poultry in the future.

    Full Text Available Mobilization of immunoglobulins (Igs-containing plasma cells (IgA, IgG and IgM in the spleen, bursa of Fabricius and thymus was investigated in broiler chickens that were vaccinated with Newcastle disease virus (NDV vaccine. In the thymus, the Igs-containing plasma cells were distributed in the cortex and medulla. Their frequency and distribution were higher at D14 and at D28. The number of IgG- and IgM-positive cells was greater than IgA-positive cells in thymus. In the bursa of Fabricius, Igs-containing plasma cells were distributed beneath the capsules; within and around the bursal follicles. Their frequency of occurrence significantly peaked at D14 and at D28 in comparison to day-old chickens, and IgG-positive cells were significantly greater than the IgA- and IgM-positive cells in the bursa of vaccinated chickens. In the spleen, Igs-containing plasma cells were distributed in the white pulp, around the trabeculae, and in the periarterial lymphatic sheath. In this secondary lymphatic tissue, IgG- and IgM-positive cell numbers significantly greater than IgA-positive cells. In conclusion, mobilization of more Igs-positive cells in lymphoid tissues of broiler chickens is due to the effect of NDV vaccine as well as the advancement of age.

    The aim of this study was to evaluate the protective effects of the turmeric in comparison to vitamin E on bursal damages induced by salinomycin in broiler chickens. In this study, forty one day-old broiler chicks were randomly divided into four treatment groups: 1- basal diet as control, 2- basal diet plus salinomycin, 3- basal diet plus salinomycin (SLM) and vitamin E (Vit. E) and 4- basal diet plus salinomycin and turmeric powder. The chicks were treated for two weeks. At the end of the experiment, the bursal tissues were removed and fixed in 10% formalin solution. Tissue sections were stained with hematoxylin and eosin stain for histopathological studies. Light microscopic observations showed that, SLM diminished cortex thickness of bursal tissue, enhanced its medulla zone and caused severe lymphocytic necrosis. In addition, SLM led to fibrosis of interstitium along with sever edema of medulla zone in the bursal tissue of the chicken. Administration of Vit. E and TP significantly inhibited the SLM-induced derangements and comparing the Vit. E and TP showed no significant differences. The results of this study indicated that the turmeric may protect bursa of Fabricius against toxicity induced by salinomycin in chicks.

    Immunoglobulin gene rearrangement in avian B cell precursors generates surface Ig receptors of limited diversity. It has been proposed that specificities encoded by these receptors play a critical role in B lineage development by recognizing endogenous ligands within the bursa of Fabricius. To address this issue directly we have introduced a truncated surface IgM, lacking variable region domains, into developing B precursors by retroviral gene transfer in vivo. Cells expressing this truncated receptor lack endogenous surface IgM, and the low level of endogenous Ig rearrangements that have occurred within this population of cells has not been selected for having a productive reading frame. Such cells proliferate rapidly within bursal epithelial buds of normal morphology. In addition, despite reduced levels of endogenous light chain rearrangement, those light chain rearrangements that have occurred have undergone variable region diversification by gene conversion. Therefore, although surface expression of an Ig receptor is required for bursal colonization and the induction of gene conversion, the specificity encoded by the prediversified receptor is irrelevant and, consequently, there is no obligate ligand for V(D)J-encoded determinants of prediversified avian cell surface IgM receptor.

    Full Text Available High environmental temperatures may cause heat stress in poultry. This may increase water consumption, decrease feed consumption and in rum, decrease productivity level. In addition, high temperature contributes to oxidative stress, a condition where oxidant activity (free radica ls exceeds antioxidant activity. In our research, antanan (Centelta asiatica and vitamin C were utilized as anti heat-stress agents for heat-stressed broilers. We used 120 male broilers 2 - 6 weeks old, kept at 31.98 ± 1.94 °C during the day and 27.36 ± 1.31 °C at night. The data collected were analyzed with a completely randomized factorial design of 2 x 3 (2 levels of vitamin C, 3 levels of antanan at 4 replications and continued with the contrast-orthogonal test when significantly different. The results indicate that the treatments of 5 and 10% of antanan with or without 500 ppm of vitamin C and vitamin C alone significantly (P<0.05 decreased the heterophil/lymphocyte (H/L ratio and liver malonaldchydc (MDA. These treatments, however, significantly (P<0.05 increased the bursa of Fabricius weight, feed consumption and body weight gain. It could be concluded that basal ration administered with 5% antanan and 500 ppm vitamin C could effectively prevent broilers from heat stress. The results support the conclusion that a ba sal ration supplemented with 5% antanan and 500 ppm of vitamin C or their combinations, effectiv elly reduces heat stress in broilers.

  20. The role of the bursa of Fabricius in the immune response to vaccinal antigens and the development of immune tolerance in chicks (Gallus domesticus) vaccinated at a very young age.

    Vaccination is recognized to be the most cost-effective means of preventing, controlling, and even eradicating infectious diseases. Conventional poultry are vaccinated through various routes including eye/nose drops, drinking water, vent brush, or injection. Efficient vaccination is an essential part of any good poultry management.The bursa of Fabricius is intimately connected to the cloaca and the intestinal system. It is well-known as a primary lymphoid organ in the chicken and a major channel through which environmental antigens stimulate the immune system. In this study we tested whether direct instillation of various viral vaccines and antigens into the cloaca (per bursam), could stimulate higher antibody titers and generate improved protection. Despite the very rapid absorption of the vaccines or antigens from the cloaca to the lumen of the Bursa of Fabricius, per bursam inoculation failed to generate a satisfactory immune response. In contrast conventional administration of live or inactivated commercial vaccines led to an acceptable level of seroconversion and protection against challenge.An interesting finding in this study was the fact that administration of a single priming dose of antigenic material at age 1 or 5 days, did not improve the response to a second administration at 14 days of age as expected. Instead, in most cases there was a reduced serum antibody response suggesting the induction of tolerance. This was true for all routes of administration (intramuscular, per ocular and per bursam) and for all formulations of vaccine.The current study reveals: 1) no advantage for direct application of live or inactivated vaccines or antigens into the bursa of Fabricius compared to common routes of vaccination, 2) that apparent desensitization or tolerance effects have important implications for poultry management, since in many countries, vaccination of day old chicks is compulsory or a well-accepted part of flock vaccination.According to our results

    When assessing joints with various imaging modalities, it is important to focus on the extraarticular soft tissues that may clinically mimic joint pathology. One such extraarticular structure is the bursa. Bursitis can clinically be misdiagnosed as joint-, tendon- or muscle-related pain. Pathological processes are often a result of inflammation that is secondary to excessive local friction, infection, arthritides or direct trauma. It is therefore important to understand the anatomy and pathology of the common bursae in the appendicular skeleton. The purpose of this pictorial essay is to characterize the clinically relevant bursae in the appendicular skeleton using diagrams and corresponding multimodality images, focusing on normal anatomy and common pathological processes that affect them. The aim is to familiarize radiologists with the radiological features of bursitis. PMID:21966619

    Serous bursae consist of a synovial membrane enveloping a film of liquid. They are located at interfaces between moving structures where friction must be reduced. The bicipitoradial bursa lies between the distal tendon of the biceps brachii, which it surrounds, and the radial tuberosity. It is a relatively large bursa, with dimensions ranging from 2.4 to 3.9 cm. It sometimes presents septation. It does not communicate with the joint cavity, but it may communicate with the interosseous bursa of the elbow. Regardless of its cause, bicipitoradial bursitis presents as a mass in the cubital fossa and/or with neurological symptoms (sensorial and/or motorial) caused by compression of the radial nerve. On ultrasonography, the inflamed bursa is visualized as an anechoic formation surrounding the distal biceps tendon. In addition to its role in diagnosing the bursitis, sonography can provide information about radial nerve injury (in the presence of macroscopic damage), and it can also be used for guidance during intrabursal injections.

    The authors present a review of the anatomy of the major bursae around the shoulder joint and discuss the use of the different imaging modalities which demonstrate their radiologic features. The calcified subacromial-subdeltoid bursa has a characteristic appearance on plain radiographs. When inflamed it can be visualized by ultrasound and magnetic resonance imaging. Calcific bursitis may involve the subcoracoid bursa. This bursa may mimic adhesive capsulitis of the shoulder or complete rotator cuff tear when injected inadvertently during shoulder arthrography. Less well known are three coracoclavicular ligament bursae. These are also subject to calcific bursitis and have a typical radiologic appearance. (orig.). With 6 figs.

    Adhesions occur in the navicular bursa between the deep digital flexor tendon (DDFT) and other structures. Our objectives were to describe the appearance of navicular bursa adhesions on high-field magnetic resonance (MR) images, to compare these findings to findings at navicular bursoscopy, and to determine the prevalence of lesions in the remainder of the podotrochlear apparatus. Sixteen forelimbs from 14 horses that underwent MR imaging and navicular bursoscopy were evaluated. Adhesions were considered type 1 when characterized by a discontinuity in the navicular bursa fluid signal between two structures, type 2 when the navicular bursa fluid signal was disrupted and ill-defined tissue was present between two structures, and type 3 when the fluid signal was disrupted and well-defined tissue was present between two structures. Twenty-six adhesions were suspected on MR images and nineteen were visualized at surgery. The positive predictive value was 50% for type 1 adhesions, 67% for type 2 adhesions, and 100% for type 3 adhesions. Additional lesions were detected in the navicular bursa in 15 limbs, the DDFT in 13, the navicular bone in 15, the collateral sesamoidean ligaments in 9, and the distal sesamoidean impar ligament in 8. A discontinuity in the navicular bursa fluid signal with well-defined tissue between two structures detected on high-field MR images is diagnostic for a navicular bursa adhesion. Additional lesions in the podotrochlear apparatus are common in horses with navicular bursa adhesions. © 2012 Veterinary Radiology & Ultrasound.

    Primary synovial osteochondromatosis (SOC) is known to be intra-articular and wherever it is observed outside a synovial joint, it is associated with the involvement of the nearby joint. Primary SOC has not been reported to involve a subdeltoid bursa. We present a case of a 52-year-old woman having a large number of loose bodies in a large tumor in the subdeltoid bursa. The swelling was first noticed by the patient 2 years back. Plain roentgenogram revealed soft tissue swelling only with no areas of calcification. On MRI, multiple nonosseous loose bodies were visualized in the bursa deep to the deltoid muscle. A surgical excision of subdeltoid bursa was done. A biopsy confirmed it to be cartilaginous loose bodies in synovial lining sugestive of metaplastic transformation of the synovial tissue.

    The purpose of this study was to document the existence of transverse cords in olecranon bursae in patients undergoing excision of the bursa and to describe the unique clinical presentation of patients with these cords. A retrospective study was performed on 24 patients who had surgery to excise an olecranon bursa between 2006 and 2011. The patient's history, preoperative radiographs, ultrasound images, intraoperative photographs, and findings on histologic analysis were reviewed in all cases. Nine olecranon bursae had cords (cord group) and 15 did not have cords (noncord group). All patients in the cord group were male manual laborers, and nearly all had olecranon enthesophytes (n = 8). Patients in the noncord group had associated medical conditions or an infection. A higher level of satisfaction was reported in the noncord group after surgical excision. This study documents the existence of transverse cords oriented at right angles to the long axis of the olecranon. Olecranon bursae with cords have a unique presentation and are found in male manual workers, are nearly always associated with an olecranon enthesophyte, and do not present with infections.

    2006-08-01

    We retrospectively reviewed 37 cases of resection of the olecranon bursa and noted wound healing problems in 10 (27%) and recurrence in 8 (22%). A lateral arm flap was necessary in one patient. Conservative treatment remains the treatment of choice for olecranon bursitis. Differentiation between septic and non-septic cases is challenging. The risk of wound healing problems and recurrence should be taken into account when planning surgical resection.

    A bursa is an extra-articular sac that may communicate with a joint and functions to decrease friction between tendons and either bone or skin. Bursae can be classified as native and non-native (adventitious) bursae. The native bursae are lined with a synovial membrane and occur at predictable anatomical sites; knowledge of these normal structures can help distinguish them from other pathological entities. An adventitious bursa can form at sites of friction rather than at predictable anatomical sites, but otherwise have imaging features similar to native bursae. Bursal distention can occur from many pathological processes, most commonly resulting from chronic overuse injury. When imaging bursal pathological conditions, there is often an overlap of imaging findings, regardless of the cause. In general, ultrasound of a distended bursa reveals a fluid collection with either simple anechoic or more complex hypoechoic fluid. Bursal distention is characteristically unilocular and compressible, unlike other structures such as ganglion cysts, which are usually multilocular and non-compressible. This article reviews the anatomical locations of common bursae and shows pathological examples using ultrasound. Knowledge of typical locations and imaging appearances of bursae can aid in narrowing the differential diagnosis and guiding further management and treatment decisions.

    The types of thirty-two nominal weevil species described by Johann Christian Fabricius are reviewed and lecto- and paralectotypes are designated for twenty-two of them. A neotype is designated for Curculiosticticus Fabricius, 1777. Protapionvaripes (Germar, 1817) is declared a nomen protectum over Curculioflavipes Fabricius, 1775. Based on a study of syntypes, Rhinomacercurculioides Fabricius, 1781 is confirmed as a member of Mycterus (Mycteridae), Bruchusundatus Fabricius, 1787 is tentatively transferred to Erotylidae, Curculiofulvirostris Fabricius, 1787 and Anthribusroboris Fabricius, 1798 are confirmed as members of Salpingus (Salpingidae), and Brachyceruscristatus Fabricius, 1798 is transferred to Tenebrionidae. Based on lectotype designation, Curculiocaninus Fabricius, 1792 is confirmed as a synonym of Sitonalineatus (Linnaeus, 1758) and Curculioinnocuus Fabricius, 1802 as a synonym of Cneorhinusbarcelonicus (Herbst, 1797). Bruchusrufipes Fabricius, 1792 is not considered an available species name, but a later use of Bruchusrufipes Olivier, 1790. Cossonusincisus Pascoe, 1885 is reinstated as valid from synonymy under Cossonusilligeri Champion, 1909 and Cossonusvulneratus Illiger, 1805 from synonymy under Cossonuscanaliculatus (Fabricius, 1792) (a primary homonym of Curculiocanaliculatus Olivier, 1791). Cossonuscanaliculatus Fabricius, 1802 is a secondary homonym of the former and is replaced with Cossonusincisus. Salpingusfulvirostris (Fabricius, 1787) is reinstated as valid from synonymy under Salpingusplanirostris (Fabricius, 1787), a primary homonym of Curculioplanirostris Piller & Mitterpacher, 1783. The following new combinations are proposed: Brachysomuserinaceus (Fabricius, 1802) (from Curculio), Bronchusferus (Gyllenhal, 1840) (from Hipporhinus), Bronchusglandifer (Fabricius, 1792) (from Curculio), Bronchusnivosus (Sparrman, 1785) (from Curculio), Bronchussparrmani (Gyllenhal, 1833) (from Hipporhinus), Coelocephalapionatrirostre (Fabricius, 1802

    The purpose of this study was to evaluate the effectiveness of corticosteroid injections into the greater trochanteric bursa as opposed to the subgluteus medius bursa in patients with greater trochanteric pain syndrome. We retrospectively reviewed 183 injections (149 performed in women, 34 performed in men; age range 23-90 years; median, 53 years) performed for treatment of greater trochanteric pain syndrome. A 10-cm visual analog scale survey was used to assess pain level before the procedure and 14 days after the procedure. A 3-mL corticosteroid solution was injected into either the greater trochanteric bursa or the subgluteus medius bursa under direct ultrasound guidance. Procedure images were retrospectively reviewed to determine the site of injection. Diagnostic images obtained at the time of the procedure were also reviewed for findings of tendinopathy, bursitis, and enthesopathy. Statistical analysis of differences in pain reduction was performed, as was analysis for association between pain relief and demographic variables of age, sex, previous injections, and ultrasound findings. Sixty-five injections met the inclusion criteria; 56 performed in women and nine performed in men (age range, 30-82 years; median, 53 years). Forty-one injections were into the greater trochanteric bursa and 24 into the subgluteus medius bursa. There was a statistically significant difference in pain reduction between greater trochanteric bursa and subgluteus medius bursa injections with a median pain reduction of 3 as opposed to 0 (p bursa may be more effective than injections into the subgluteus medius bursa for treatment of greater trochanteric pain syndrome.

    The goal of the study was to perform a detailed anatomical description of the retrocalcaneal bursa (RB). Its morphological arrangement was studied on 10 fresh and 30 embalmed lower extremities by microdissection and light microscopy. The RB was present constantly and in all the cases contained 1-2 cm long synovial fold, beginning on the upper wall of RB and distally interposed between the anterior surface of the Achilles tendon and the posterior surface of the calcaneal tuberosity. The volume of RB was 1-1.5 ml. The histological analysis confirmed that the inner surface of the superior and posterior wall of RB have been covered by unilayered synovial membrane, projecting into synovial villi of different shapes and sizes. In the ceiling of RB, delicate fascicle of skeletal muscle fibers was discovered, radiating distally into the regularly present synovial fold. The whole bottom of RB has been covered by 200-500 microm layer of fibrous cartilage into which the calcaneal tendon attached. The cartilagineous layer continued anteroproximally to cover the whole bursal surface of the calcaneal tuberosity, where the thickness of the cortical bone was reduced on mere 50 microm. The obtained results can be used in the improvement of the differential diagnostics and therapy of diagnostics and therapy of the retrocalcaneal bursitis as well as of other kinds of achillar enthesopathies and heel pain.

    Draghi, F; Gregoli, B; Sileo, C

    2012-02-01

    Serous bursae consist of a synovial membrane enveloping a film of liquid. They are located at interfaces between moving structures where friction must be reduced. The bicipitoradial bursa lies between the distal tendon of the biceps brachii, which it surrounds, and the radial tuberosity. It is a relatively large bursa, with dimensions ranging from 2.4 to 3.9 cm. It sometimes presents septation. It does not communicate with the joint cavity, but it may communicate with the interosseous bursa of the elbow. Regardless of its cause, bicipitoradial bursitis presents as a mass in the cubital fossa and/or with neurological symptoms (sensorial and/or motorial) caused by compression of the radial nerve. On ultrasonography, the inflamed bursa is visualized as an anechoic formation surrounding the distal biceps tendon. In addition to its role in diagnosing the bursitis, sonography can provide information about radial nerve injury (in the presence of macroscopic damage), and it can also be used for guidance during intrabursal injections.

    2010-01-01

    Lipoma arborescens is a benign, diffuse villous proliferation of the synovium characterized by replacement of the subsynovial tissue by mature adipocytes. Its etiology is unknown and fewer than 100 cases have been reported. It resembles other collections of subsynovial fat, the only difference being its large size and villous macroscopic appearance. It typically presents in patients in their fifth through seventh decades of life. It is most commonly monoarticular and most frequently affects the suprapatellar pouch of the knee. There have been reports of involvement of the hip, shoulder, wrist, elbow, ankle, and associated bursae. To our knowledge there have been only three previous cases of lipoma arborescens of the subdeltoid bursa in the literature. We report on a case of unilateral lipoma arborescens of the subdeltoid bursa in an elderly patient presenting as a shoulder mass.

    This paper aims to assess the prevalence and relevance of the bursa-synovial lesion in spondyloarthritis (SpA). A transversal blind and controlled two-dimensional (2D) and three-dimensional (3D) ultrasound (US) study of Achilles enthesis bursa in early SpA was undertaken. Clinical outcome measures were collected. Bilateral Achilles enthesis of 66 early SpA patients (34 women) and 46 control patients (23 asymptomatic healthy subjects and 23 rheumatoid arthritis [RA] patients) were analysed. Mean BASDAI, BASFI and BASRI-spine were 4.55±2.08, 2.16±1.95 and 0.65±0.77, respectively. Mean erythrocyte sedimentation rate (ESR) was 10.93±12.35 mm/h and C-reactive protein (CRP) was 6.46±10.09 mg/l. The κ-values for intra-reader agreement for 2D and 3D images and bursa measurement were 0.82 and 0.98, respectively. Bursas were visualised in 89/132 SpA enthesis (67.4%) vs. 27/46 enthesis (58.7%) of healthy controls (pbursas were analysed, the SpA group had a mean of 1.52±1.47 mm versus 0.76±0.76 mm in the healthy control group (pbursa >2 was found. No Doppler signal was detected in controls, but 6.6% of SpA Achilles enthesis had Doppler bursitis. Heel pain was more frequent when bursa was present (pbursa and Doppler signal at retrocalcaneal bursa level could have a relevant contribution to differentiate SpA patients, and were correlated with clinical outcomes of SpA disease activity.

    To describe the anatomic features of the equine trochanteric bursa and to evaluate 4 techniques for bursa centesis. Prospective, randomized design. Equine cadavers (n=2) and 20 live horses. The trochanteric bursae of 2 equine cadavers were injected with latex to identify the boundaries of the bursae. Four techniques for centesis of the trochanteric bursa were evaluated by attempting to inject dye into both trochanteric bursae of 20 live horses. Techniques included injection of the bursa with the limb-bearing weight and injection with the limb nonweight bearing and supported on a block, with or without ultrasonographic guidance of the needle. Ultrasonographic guidance of the needle was performed with or without the use of a guide channel attached to the ultrasound probe. Each of the 4 techniques was used to inject 10 bursae. The region of the bursa was dissected after horses were euthanatized to determine the location of the dye. The trochanteric bursa was most successfully injected with the limb positioned caudally with the foot on a block, even though topographic landmarks for centesis were more difficult to identify when the limb was in this position. The highest incidence of success was achieved when the needle was inserted using ultrasonographic guidance with the foot in a Hickman block. Positioning the limb caudally with the foot nonweight bearing and on a block facilitated centesis of the trochanteric bursa. © Copyright 2011 by The American College of Veterinary Surgeons.

    Hornets possess highly toxic venoms, which are rich in toxins, enzymes and biologically active peptides. Many bioactive substances have been identified from wasp venoms. Vespa mastoparan (MP-VBs) and Vespa chemotatic peptide presenting antimicrobial action (VESP-VBs) were purified and characterized from the venom of the wasp, Vespa bicolor Fabricius. The precursors encoding VESP-VBs and MP-VBs were cloned from the cDNA library of the venomous glands. Analyzed by FAB-MS, the amino acid sequence and molecular mass for VESP-VB1 were FMPIIGRLMSGSL and 1420.6, for MP-VB1 were INMKASAAVAKKLL and 1456.5, respectively. The primary structures of these peptides are homologous to those of chemotactic peptides and mastoparans isolated from other vespid venoms. These peptides showed strong antimicrobial activities against bacteria and fungi and induced mast cell degranulation, but displayed almost no hemolytic activity towards human blood red cells.

    The purpose of this study was to describe the appearance and ultrasound characteristics of the Gruberi bursa using a cadaveric model and retrospective ultrasound imaging review. For the cadaveric study, ultrasound of the dorsolateral ankle of a foot-ankle specimen was performed and was followed by injection of latex between the extensor digitorum longus (EDL) tendons and the talus and dissection. For the ultrasound imaging review, the radiology database was searched for ultrasound studies performed from September 15, 2000, through April 1, 2015, to identify subjects with a dorsolateral foot or ankle fluid collection detected on ultrasound. Images were retrospectively reviewed to characterize the location and size of the fluid collection, assess for the number of locules, and evaluate the compressibility of the fluid collection. It was determined whether the ultrasound findings were significantly different from chance: CI and p values were obtained from performing a test for one proportion. Dissection of a cadaveric specimen revealed latex within a well-defined region between the EDL tendons and the dorsolateral talus; this location is consistent with a Gruberi bursa. For the image review, the imaging examinations of 162 subjects (age range, 16-88 years; 31 male subjects and 131 female subjects) were reviewed. On the ultrasound images, a fluid collection with its epicenter between the dorsolateral talus and EDL was found in 93% of ankles. Of the fluid collections identified on ultrasound, 98% were unilocular and 94% were anechoic. Of these fluid collections, 133 were assessed for compressibility, and 89% were compressible. The positive findings for a Gruberi bursa that were different from chance (p bursa characteristically is located between the EDL and the talus; on ultrasound, the Gruberi bursa is most commonly unilocular, anechoic, and compressible.

    Programmed suicide or apoptosis, due to activation of endogenous nucleases, occurs in immature CD4{sup {minus}}85{sup {minus}} mammalian thymus cells. Like the thymus, the bursa of Fabricius is a site of massive lymphopoiesis accompanied by cell death in vivo. In the present study the authors have, therefore, examined whether chicken bursa and thymus cells exhibit apoptosis. Bursa and thymus cells from SC chickens, 4-10 weeks of age, were incubated for 8-24 hrs with various reagents. Genomic DNA was isolated, electrophoresed in 3% Nusieve agarose gels, and examined for patterns of DNA fragmentation. A laddering of DNA in multiples of 200 base pairs, indicative of apoptosis, was observed with both bursa and thymus cells. These patterns of DNA fragmentation from bursa cells could be prevented by adding phorbol myristic acetate during culture and, more effectively, by PMA plus ionomycin, but not by ionomycin alone or by anti-{mu}. PMA did not affect the patterns of DNA fragmentation seen with spleen cells. Addition of the protein kinase C inhibitor staurosporin inhibited the preventive effect of PMA on apoptosis. PMA also greatly promoted the survival of bursa cells in culture, as assayed by percentage cell death and by {sup 3}H-thymidine incorporation. It is concluded that bursa and thymus cells from the chicken exhibit apoptosis. The data further suggest that protein kinase C activation protects apoptosis in cultured bursa cells.

    The subacromial bursa (SAB) is the main bursa of the shoulder. It facilitates normal movement and is also commonly involved in shoulder disorders. Other shoulder bursae have been described but their anatomy has not been well studied. Anatomical variation of shoulder bursae has been suggested and this has implications for clinical practice. This article reviews current knowledge of the normal anatomy of the SAB and related shoulder bursae. A systematic review of the English and German literature was conducted using databases and a hand search of reference lists focusing on the clinical anatomy of the SAB, coracobrachial and subcoracoid bursae and subtendinous bursa of subscapularis. Twenty-four original sources and 13 textbooks were identified. Fifteen studies described the general morphology of the shoulder bursae using cadaveric specimens, eight examined innervation, and one provided information about the blood supply of the SAB. The literature agrees that the SAB is consistent and well innervated with a lateral subdeltoid part and a variable subcoracoid portion. There is variability regarding the consistency, location, and communications of the coracobrachial and subcoracoid bursae and the superior part of the subtendinous bursa of subscapularis, and little information on their nerve and blood supply. Several bursae are present around the shoulder joint. Further research is warranted to understand the precise attachments, dimensions, and communications of the bursae, as well as their nerve and blood supply. This information will improve understanding of the clinical relevance of these bursae and inform appropriate assessment and treatment. Clin.

    Bursal chondromatosis is synovial chondromatosis of the bursae. It is a rare disease entity that can involve the adventitial bursa of the lateral ankle. Complete synovectomy, removal of loose bodies, and bursectomy comprise the treatment of choice. Detailed preoperative radiologic assessment and surgical planning are the keys to success. Any accompanying synovial chondromatosis of the ankle or subtalar joint or tenosynovial chondromatosis of the peroneal tendon sheath should be treated together with the bursectomy. Endoscopic bursectomy can be performed through the bursal portal. The proximal and distal peroneal tendoscopy portals serve as viewing portals. The resection of the diseased tissues should be performed in a step-by-step zonal manner. Complete synovectomy and removal of loose bodies should be performed before bursectomy. Internal drainage of the bursal sac into the peroneal tendon sheath may be indicated if the sac is adherent to the skin. It should only be performed after complete synovectomy and removal of loose bodies.

    In general, a time series is simply a sequence of numbers collected at regular intervals over a period. Financial time series data processing is concerned with the theory and practice of processing asset price over time, such as currency, commodity data, and stock market data. The primary aim of this study is to understand the fundamental characteristics of selected financial time series by using the time as well as the frequency domain analysis. After that prediction can be executed for the desired system for in sample forecasting. In this study, multiresolution analysis which the assist of discrete wavelet transforms (DWT) and maximal overlap discrete wavelet transform (MODWT) will be used to pinpoint special characteristics of Bursa Malaysia KLCI (Kuala Lumpur Composite Index) daily closing prices and return values. In addition, further case study discussions include the modeling of Bursa Malaysia KLCI using linear ARIMA with wavelets to address how multiresolution approach improves fitting and forecasting results.

    The purpose of this study was to use MRI and anatomic correlation in cadavers to show the macroscopic anatomic configuration of the prepatellar bursa. MRI of the prepatellar bursa of nine cadaveric knees was performed after sonographically guided bursography. The images were compared with those seen on anatomic sectioning. Histologic analysis was obtained in two specimens. Mean dimensions of the prepatellar bursa in the craniocaudal, lateromedial, and anteroposterior planes were 39.7, 40.5, and 3.2 mm, respectively. A trilaminar aspect of the bursa was shown in seven of the nine knees (78%) and a bilaminar appearance in two of the nine knees (22%). Lateral extension of the bursa over the patella was observed in three knees (33%) and medial extension in one knee (11%). On histopathologic analysis, three potential bursal spaces were found. The prepatellar bursa is most commonly a trilaminar structure, and variation in its relation to the patella can occur.

    To compare accuracy of 2 methods for injection of the podotrochlear bursa in horses. Observational study. 17 French Standardbreds. In each horse, contrast medium was injected into the podotrochlear bursa of 1 foot by use of a distal palmar approach with the needle inserted parallel to the sole (DPPS) and into the podotrochlear bursa of the other foot by use of a distal palmar approach to the navicular position (DPNP). Podotrochlear bursa injection was evaluated by means of radiographic examination in all horses and postmortem examination in 6. Contrast medium was successfully injected into the podotrochlear bursa in 6 of 16 feet in which the DPPS method was used and 14 of 17 feet in which the DPNP method was used; these results were significantly different. Failure was attributed to contrast medium invading the distal interphalangeal joint, contrast medium pooling palmar to the deep digital flexor tendon, contrast medium located in the podotrochlear bursa and the distal interphalangeal joint, contrast medium located in the podotrochlear bursa and the area palmar to the deep digital flexor tendon, and an inability to inject contrast medium despite adequate needle placement. Results suggest that the DPNP technique can be used successfully for injection into the podotrochlear bursa in horses. However, radiographic assessment should be used to confirm that material was injected into the bursa.

    Background: Lower extremity bursae are very vulnerable to injury during strenuous physical exercises. Understanding the imaging characteristics of normal bursae is essential for early diagnosis of morphological abnormalities. Therefore, we evaluated the normal range of lower extremity bursae in healthy young men using high-resolution ultrasound (HR-US) imaging. Methods: Bursae in the lower extremities were examined by HR-US in 290 Chinese healthy young men with a median age of 18 years (range, 18–23 years). The bilateral suprapatellar bursa (SPB), deep infrapatellar bursa (DIPB), popliteal bursa (PB), and retrocalcaneal bursa (RCB) were imaged and measured for analysis. Results: The HR-US identification rates of the SPB, DIPB, PB, and RCB were 89.0% (517/580), 55.0% (319/580), 29.4% (171/580), and 49.5% (287/580), respectively. With the assumption that the bursae were normal in 95% of the study participants, the length and width values at the maximal cross-section of the SPB, DIPB, PB, and RCB were ≤18.00 and 6.09 mm, 8.10 and 2.11 mm, 7.67 and 3.93 mm, and 7.82 and 2.04 mm, respectively. Conclusions: Using HR-US imaging, we were able to analyze lower extremity bursae with high detection rates in healthy young men. The normal ranges of lower extremity bursa dimensions in healthy young men measured by HR-US in this study could be used as reference values for evaluation of bursa abnormalities in the lower extremity.

    An adult male with cerebral palsy was admitted to our institution with a massive prepatellar bursa. The condition resulted from the patient's use of crawling as a means of household ambulation. The bursa had become infected secondarily, prompting him to seek medical attention. The bursa was excised in its entirety, allowing for relief of his symptoms. The patient expired three years later from unrelated causes.

    To evaluate the presence, location, and dimensions of the deep infrapatellar bursa on routine magnetic resonance (MR) imaging of the knee. The study group consisted of 213 knees in 204 consecutive individuals who had undergone routine MR imaging examination of the knee within a 365-day period. Magnetic resonance examinations consisted of T1-, proton-density-, and T2-weighted sagittal; spectral presaturation inversion recovery coronal; and T2*-weighted transverse sequences. Exclusion criteria were previous knee arthroscopy or surgery or the presence of a mass lesion infiltrating the infrapatellar fat pad. The presence, location, and dimensions of the deep infrapatellar bursa were studied. The bursa was also analyzed with regard to knee joint synovial effusion (absent, mild, or marked). The deep infrapatellar bursa was detected in 68% of the knees, most commonly on the lateral paramedian sagittal MR images. There was no statistically significant difference between male and female subjects or between the knee sides with regard to the detection of the deep infrapatellar bursa (P > 0.05). No correlation was found between synovial effusion and the presence of the deep infrapatellar bursa. The mean anteroposterior and craniocaudal dimensions of the deep infrapatellar bursa on sagittal T2-weighted MR images were 2.1-2.7 mm and 7.3-9.1 mm, respectively, on its lateral, central, or medial location within the sagittal MR image stack. An awareness of the dimensions and location of the deep infrapatellar bursa is important in distinguishing it from pathologic lesions (eg, bursitis).

    To determine whether clinically effective concentrations of methylprednisolone or triamcinolone can be achieved in the navicular bursa after injection of methylprednisolone acetate (MPA) or triamcinolone acetonide (TA) into the distal interphalangeal joint (DIPJ) and whether clinically effective concentrations of these drugs can be achieved in the DIPJ after injecting the navicular bursa with the same doses of MPA or TA. 32 healthy horses. Horses in groups 1 through 4 received 40 mg of MPA in the DIPJ, 10 mg of TA in the DIPJ, 40 mg of MPA in the navicular bursa, and 10 mg of TA in the navicular bursa, respectively. Concentrations of corticosteroids that diffused into the adjacent synovial structure were determined. For group 1, injection of MPA into the DIPJ yielded a mean +/- SD concentration of 0.24 +/- 0.072 microg of methylprednisolone/mL in the navicular bursa. For group 2, injection of TA into the DIPJ yielded 0.124 +/- 0.075 microg of triamcinolone/mL in the navicular bursa. For group 3, injection of MPA into the navicular bursa yielded 0.05 +/- 0.012 microg of methylprednisolone/mL in the DIPJ. For group 4, injection of TA into the navicular bursa yielded 0.091 +/- 0.026 microg of triamcinolone/mL in the DIPJ. A clinically effective concentration of methylprednisolone or triamcinolone diffused between the DIPJ and navicular bursa after intra-articular or intrabursal injection, which would justify injection of the DIPJ with MPA or TA to ameliorate inflammation of the navicular bursa.

    Ossification of the infraspinatus tendon-bursa was diagnosed in 13 labrador retrievers, 12 of which were lame in one thoracic limb and the other in both. They ranged in age from 28 to 121 months (mean 69.4 months). The lameness developed gradually and was progressive in 11 of the 14 affected joints. Scapular muscle atrophy and signs of pain on direct pressure over the infraspinatus tendon of insertion were key clinical signs. Caudocranial radiographs revealed multiple mineralised masses lateral to the proximal humerus or glenohumeral joint in 11 of the 26 joints and single masses in 12. An arthroscopic examination revealed concomitant ligament or tendon abnormalities in six of seven shoulders. The dogs were followed up from one to 55 months (mean 20 months). Of five shoulders treated with non-steroidal anti-inflammatory drugs (nsaids), one resolved, two improved and two were managed surgically. Of six shoulders treated by the injection of long-acting intra-articular corticosteroid (five before and one after surgery), three resolved, two improved and one was unchanged. Of six shoulders treated by the surgical resection of the infraspinatus tendon and bursa (three before and two after treatment with nsaids, and one after treatment with a long-acting intra-articular corticosteroid), four improved, one was unchanged and one was managed with an intra-articular long-acting corticosteroid. One shoulder was managed by restricted exercise and the lameness resolved. Histological examination of the excised tissues revealed heterotopic bone within the infraspinatus tendon and/or bursa.

    Centesis of the bicipital bursa using an 8.9 cm long spinal needle has been reported but the alternative of employing a 3.8 cm long hypodermic needle requires validation. To compare the efficacy of 2 different methods of centesis of the bicipital bursa and to evaluate the usefulness of ultrasonographic imaging to determine the location of solution administered when centesis of the bursa is attempted. For Trial 1, 6 clinicians, who had no previous experience of centesis of the bicipital bursa, attempted to inject a solution composed of an aqueous radiopaque contrast medium and physiological saline solution (PSS) into the bicipital bursae of 2/12 horses using the previously described distal approach to inject one bursa and a proximal approach to inject the contralateral bursa. The bicipital tendon and bursa were examined ultrasonographically before and after injection; and both shoulders were examined radiographically to identify the location of the medium. In Trial 2, another 6 clinicians, also with no previous experience of centesis, repeated Trial 1, using 6 horses, but the radiopaque contrast medium was mixed with air instead of PSS. Accuracy of centesis using the proximal approach was 39% and that of the distal approach 28%. Ultrasonographic examination of the shoulder allowed the location of solution and air to be accurately predicted in all 12 shoulders examined. Clinicians who have had no previous experience performing centesis of the bicipital bursa are unlikely to be successful in centesis using either approach. Radiographic examination after injecting a radiopaque contrast medium may be necessary to assess the success of centesis especially if bursal fluid is not obtained during centesis. Injecting air along with the radiopaque contrast medium provides more accurate ultrasonographic confirmation of centesis and better radiographic definition than does injection without air.

    Osteochondromas are common benign bone tumors. Synovial chondromatosis is a benign cartilaginous metaplasia that occurs in the synovium. The authors describe a unique case of synovial chondromatosis developing in the pes anserine bursa secondary to an underlying osteochondroma of the proximal medial tibia. It is unusual to see both of these processes occurring simultaneously in 1 location. After appropriate consent was obtained, the patient's case was reviewed. A 17-year-old boy presented with a painless mass in the medial aspect of the right leg. Initial imaging of the right leg showed a cartilaginous-appearing lesion arising from the tibia and several distinct additional cartilaginous masses in the adjacent soft tissue. After 16 months of observation, the patient began to have increasing pain in the region of the lesion. The patient underwent surgery for excision of suspected synovial chondromatosis of the right pes anserine bursa and osteochondroma of the proximal right tibia. Postoperatively, the patient had complete resolution of symptoms and regained full range of motion of the knee. He returned to full activities, including walking and running. Osteochondromas are common benign bone tumors. Synovial chondromatosis is a benign synovial metaplastic cartilaginous proliferation that occurs primarily in joints, but can occur in any synovial-lined space. In this case report, the authors describe a unique occurrence of both of these lesions simultaneously. The treatment was excision of the osteochondroma and resection of the chondromatosis lesions, which resulted in an excellent outcome. Copyright 2014, SLACK Incorporated.

    Normally, the subacromial-subdeltoid bursa is thinner than 2 mm using ultrasound examination. The subtle thickening of the bursa could be an early sign of subacromial impingement and possibly a rotator cuff tear. The aim of this study was to compare the thickness of subacromial bursa measured using ultrasonography in the painful shoulder with normal side, and also to differentiate Neer stages I and II impingements in patients with unilateral shoulder pain. We performed bilateral shoulder sonography in 268 consecutive patients with unilateral shoulder pain and clinical suggestion of rotator cuff pathology. The study group consisted of 102 cases of Neer stage I and 166 cases of Neer stage II impingement syndrome. The bursa thickness was calculated from the superficial peribursal fat to the upper margin of the supraspinatus. A statistically significant association was detected (p bursa in patients with Neer stage I impingement had no statistically important link the results of the patients with Neer stage II impingement. Increased bursa thickness in the symptomatic side may be an alternative sonographic indicator of subacromial bursitis and partial-thickness rotator cuff tears, even when measured to be less than 2 mm. Sonographic examination of subacromial bursa thickness is not an appropriate technique to differentiate the Neer stages I and II impingement. Further study is needed to quantify the echogenicity of the supraspinatus tendon and to show a level of accuracy in patients with rotator cuff tendinosis or partial tears.

    Magnetic resonance (MR) imaging is often performed to determine the cause of palmar heel pain. We evaluated how distension of the navicular bursa affected the MR appearance of the navicular bursa and associated structures. An MR evaluation was performed on normal cadaver limbs and cadaver limbs from horses with lameness localized to the foot. The normal navicular bursae were injected with 2, 4, or 6 ml of solution. The bursae of the feet from lame horses were injected with 4 or 6 ml, and the MR study was repeated. All bursae were examined grossly to verify the presence or absence of adhesions. Clinical patients that had initial MRI abnormalities suggesting adhesions were also evaluated. Distension of the proximal recess of the normal navicular bursa, proximal to the collateral sesamoidean ligament was achieved with 2 ml. Separation of the collateral sesamoidian ligament from the deep digital flexor tendon (DDFT) was achieved with 4 ml. The separation of the navicular bone from the DDFT and distal sesamoidian impar ligament required 6 ml. Adhesions were more clearly defined in the bursa of the two pathologic cadaver limbs following distension. MR bursography used on clinical patients allowed the determination of the presence or absence of adhesions. In these horses, this determination could not have been definitively made without this technique. MR bursography is useful in horses where the presence of adhesions cannot be clearly defined by MRI. © 2011 Veterinary Radiology & Ultrasound.

    There is little information on the fetal anatomy of the posterior semimembranosus tendinous complex and its associated bursa. We examined histological sections (transverse or sagittal) of the right or left knee in 13 mid-term human fetuses (12-25 weeks of gestation). The medial head of the gastrocnemius provided an aponeurosis facing or attached to the muscles of the pes anserinus by 12 weeks of gestation. The peritendinous tissue of the semimembranosus provided a bursa continuous with a laterally extending plate-like tissue by 15 weeks, but sometimes the typical bursa was absent. The aponeurosis of the medial head consistently accompanied a bursa-like space (false bursa) surrounded by heterogenous structures including the popliteus and a wall of the semimembranosus bursa. Sagittal sections displayed notches on the medial head surface that received the semimembranosus and semitendinosus overriding the medial head of the gastrocnemius. In contrast to a real bursa originating from the peritendinous tissue of the semimembranosus, a false bursa without a homogeneous wall consistently develops at the origin of the medial head of the gastrocnemius. Due to mechanical stress from the tendons, the false bursa is likely to develop into a structure similar to a real bursa with a synovial lining even if the real bursa is absent in the fetus. We hypothesize that the adult gastrocnemio-semimembranosus bursa, largely or partly, originates from the fetal false bursa. Absolute resection of the false bursa is difficult because it is a mere gap between normal tissues. Copyright © 2010 Elsevier B.V. All rights reserved.

    To compare the accuracy of ultrasound (US)-guided versus unguided pes anserinus bursa injections in a cadaveric model. Single blind, prospective study. Academic institution procedural skills laboratory. Twenty-four unembalmed, unpaired adult cadaveric lower extremity specimens. A single investigator performed 12 US-guided and 12 unguided pes anserinus bursa injections using colored liquid latex into 24 unembalmed adult cadaveric lower extremity specimens. The order of the injection techniques was randomized. The specimens were subsequently dissected by a co-investigator blinded to the injection technique used for each injection. The injections were graded for accuracy as follows: accurate (all injectate contained within the pes anserinus bursa), accurate with overflow (injectate within the pes anserinus bursa, but also located in adjacent structures), or inaccurate (injectate not within the pes anserinus bursa). The accuracy of the 2 approaches was compared using Pearson chi(2) test with Williams' correction for the small sample size (P = .05). The accuracy rate was 92% (11 of 12 specimens) in the US-guided condition and 17% (2 of 12 specimens) in the unguided condition. One US-guided injection was considered accurate with overflow, whereas 4 unguided injections were accurate with overflow. The US-guided injection technique was significantly more accurate than the unguided technique (Williams-corrected chi(2) = 12.528, P bursa injections rarely place the injectate within the pes anserinus bursa, whereas US-guided pes anserinus bursa injections have a high degree of accuracy. Therefore, clinicians should consider using US-guidance for diagnostic or therapeutic pes anserinus bursa injections when indicated.

    The bicipitoradial bursa lies at the insertion of the biceps tendon on the radial tuberosity. It is an unusual site for chronic bursitis and most often, results from repetitive mechanical trauma or overuse. Other causes include tuberculosis, immunological complications of the rheumatological disease, for example, psoriatic arthropathy, rheumatoid arthritis and synovial chondromatosis. Unlike ganglion cyst arising from the elbow joint, resection of the bursa through the elbow arthroscopy is not possible as the bursa is not communicated with the joint. We reported a patient with rheumatoid arthritis presenting with bicipitoradial bursitis extended around the radial neck which was successfully resected endoscopically.

    Three patients with chronic renal failure who received therapy with hemodialysis through arteriovenous fistulas in the forearm had fluctuating swelling over the elbow on the same side as the fistula used for the dialysis. The clinical findings in each case were compatible with olecranon bursitis with effusion. The aspirate obtained from the swellings contained lymphocytes, polymorphonuclear leukocytes and histiocytes, a finding similar to that in cases of uremic pericardial and pleural effusion. Biopsy of the bursa in one case showed hyalinized collagenous tissue with infiltration by histiocytes and lymphocytes, reflecting underlying chronic inflammation. Uremia was believed to be the causative factor. Bursitis with effusion is considered to be one of the clinical aspects of uremic polyserositis. Images FIG. 1 FIG. 2 PMID:638913

    The use of arthroscopic techniques for excision of the pre-patellar bursa has become more common in recent years for the treatment of prepatellar bursitis. The current literature includes several case series that report few complications with this technique. We report the case of a 73-year-old male who sustained a low-energy patella tendon rupture 2 months after arthroscopic resection of the prepatellar bursa. We hypothesize that during arthroscopic excision of the prepatellar bursa there was an iatrogenic injury to the patellar tendon, which contributed to the subsequent rupture. Surgical repair was successfully performed using an open technique with a 1-year follow-up. To our knowledge, this is the first case report of patella tendon rupture following arthroscopic excision of the prepatellar bursa.

    An exceptional complication of a slight sports injury of the knee with rupture of the semimembranosus bursa in a 29-year-old male football player is reported. The diagnosis was verified by immediate arthrography, consequently the possibility of thrombophlebitis could be ruled out. Anticoagulation is dangerous and contraindicated in rupture of the semimembranosus bursa due to the risk of developing compartment syndrome. Simple bed-rest for a week gave complete relief of pain.

    Synovial chondromatosis of the subacromial bursa has been reported rarely. To the best of our knowledge, there was no case report of arthroscopic treatment for synovial chondromatosis of the subacromial bursa in English literature. The authors present a case of synovial chondromatosis of the subacromial space in a 45-year-old male, which was managed by arthroscopy. This rare condition can be well managed on similar lines as the other joints through arthroscopic surgery.

    Vascularity of the subacromial bursa and rotator cuff tendons is key factors in the pathogenesis of subacromial bursitis and impingement syndrome, rotator cuff tendinitis, and rotator cuff tears. The purpose of this study was to investigate and describe blood supply to the cranial and caudal parts of the subacromial bursa and the vascularity of the rotator cuff tendons on the bursal side. Fourteen fresh cadaveric shoulders from six females and eight males with a mean age of 71.7 (±10.8) years were studied. Before dissection, an arterial injection of 10% aqueous dispersion of latex was administered. Post-injection, the shoulders were fixed in an alcohol-formalin-glycerol solution. The cranial and caudal bursa of all specimens was mainly supplied by the thoracoacromial, suprascapular, and anterior and posterior circumflex humeral arteries. The cranial part of the bursa was supplied anteriorly by the thoracoacromial artery, and posteriorly and medially by the posterior circumflex humeral artery as far as the medial third. The caudal part received arterial blood anteriorly from the anterior circumflex humeral artery, and posteriorly and medially by the posterior circumflex humeral artery as far as the medial third of the caudal bursa. In addition, the suprascapular artery branched at the upper surface of the coracohumeral ligament, and the subcoracoid artery branched at the under surface of the same ligament. The subacromial bursa appears well vascularized. The results of the present investigation showed that blood supply to the subacromial bursa at the caudal part and rotator cuff tendons on the bursal side was linked to the same arteries. The subcoracoid artery supplied interval rotator structures close to the caudal bursa. It is the wish of the authors that this meticulous anatomical work will help surgeons in their day-to-day clinical work, e.g. to minimize the risk of complications such as perioperative bleeding.

    Primary synovial chondromatosis is a benign neoplastic process, occurring mostly in large joints, more rarely in tendon sheaths, and extremely uncommonly in bursae. We describe a patient with primary synovial chondromatosis arising in the fourth intermetatarsal bursa. Knowledge of the bursal anatomy of the forefoot, and of characteristic imaging findings and the pathogenesis of synovial chondromatosis, is essential in including this uncommon entity in the differential when occurring in unusual locations.

    Diagnostic navicular bursoscopy has been described in limited cases. Review of greater numbers is needed to define its contribution to case management and prognostic values. To report: 1) clinical, diagnostic and endoscopic findings in a series of cases, 2) surgical techniques and case outcomes and 3) prognostic values. The authors hypothesise: 1) lameness localising to the navicular bursa is commonly associated with dorsal border deep digital flexor tendon (DDFT) lesions, 2) endoscopy allows extent of injuries to be assessed and treated, 3) case outcome relates to severity of DDFT injury and 4) the technique is safe and associated with little morbidity. All horses that underwent endoscopy of a forelimb navicular bursa for investigation of lameness were identified. Case files were reviewed and those with injuries within the bursa selected for further analysis. One-hundred-and-fourteen horses were identified. Ninety-two had injuries within the bursa and DDFT injuries were identified in 98% of bursae. Of those examined with magnetic resonance imaging (MRI), 56% had combination injuries involving the DDFT and navicular bone. Sixty-one percent of horses returned to work sound, 42% returned to previous performance. Horses with extensive tearing and combination injuries of the DDFT and navicular bone identified with MRI, had worse outcomes. Lameness localising to the navicular bursa is commonly associated with injuries to the dorsal border of the DDFT. Endoscopy permits identification and characterisation of injuries within the navicular bursa and enables lesion management. Outcome following debridement is related to severity of injury but overall is reasonable. Horses with lameness localising to the navicular bursa may have tears of the DDFT. Bursoscopy is able to contribute diagnostic and prognostic information and debridement of lesions improves outcome compared to cases managed conservatively. © 2011 EVJ Ltd.

    To describe the volume and dimensions of the bicipital bursa and its position in relation to bony and soft tissue structures, in order to develop a novel medial synoviocentesis approach to the bicipital bursa. Cadaveric study. Adult equine cadaver limbs (n=19). Bicipital bursa dimensions, volume, and relationship to bony structures were obtained from positive contrast computed tomography images after distension of the bursa (n=7). Following an intra-bursal injection of polyurethane resin, the bicipital bursa (n=4) was dissected and its relationship to soft tissue structures described. After computed tomography and dissection, a novel medial bicipital bursocentesis approach was investigated on intact cadavers (n=8). Median (range) of measurements were: length 9.02 cm (8.48-9.45 cm); width 7.06 cm (6.71-8.01 cm); and volume 51 mL (45-58 mL). The medial aspect of the bicipital bursa was located at the junction of the subclavius and biceps muscles, which corresponds with the externally visible lateral pectoral sulcus. Needle insertion 5-10 mm craniolateral to the center of the lateral pectoral sulcus midway between the palpable distal aspect of the deltoid tuberosity and the cranial part of the greater tubercle was found to be a reliable landmark for the novel medial bursocentesis approach. This approach was successful in all cadavers. The novel approach to the bicipital bursa provided access to the medial aspect of the bursa and is an alternative to the lateral approaches. Further validation in live horses is warranted to establish the safety and efficacy of this technique. © Copyright 2016 by The American College of Veterinary Surgeons.

    Septic peritonitis occurs relatively commonly in dogs. Secondary septic peritonitis is usually associated with perforation of intestines or infected viscera, such as the uterus in pyometra cases. The aim of this study was to evaluate the bacterial flora in the ovarian bursae of intact bitches as a potential source of contamination. One hundred forty dogs, clinically suspected of pyometra, were prospectively enrolled. The control group consisted of 26 dogs that underwent elective ovariohysterectomies and 18 dogs with mammary gland tumors that were neutered at the time of mastectomy. Bacteriology samples were taken aseptically at the time of surgery from the bursae and the uterus in all dogs. Twenty-two dogs that were clinically suspected of pyometra had sterile uterine content ("mucometra" cases); the remaining 118 had positive uterine cultures ("pyometra" cases) and septic peritoneal fluid was present in 10% of these cases. Of the 118 pyometra cases, 9 had unilateral and 15 had bilateral bacterial colonization of their ovarian bursae. However, the bacteria from the ovarian bursa were similar to those recovered from the uterine pus in only half of the cases. Furthermore, positive bursae were also seen in one mucometra dog (unilateral) and in four control dogs (two unilateral and two bilateral). The data illustrate that the canine ovarian bursa can harbor bacteria. The biological importance of these isolations remains unclear. Copyright © 2014 Elsevier Inc. All rights reserved.

    In a condition of pain in the Achilles tendon insertion there are multiple structures involved, such as the Achilles tendon itself, the retrocalcaneal bursa and a bony protrusion at the calcaneal tuberosity called Haglund's deformity. The innervation patterns of these structures are scarcely described, and the subcutaneous calcaneal bursa is traditionally not considered to be involved in the pathology. This study aimed at describing the innervation patterns of the four structures described above to provide a better understanding of possible origins of pain at the Achilles tendon insertion. Biopsies were taken from 10 patients with insertional Achilles tendinopathy, which had pathological changes in the subcutaneous and retrocalcaneal bursae, a Haglund deformity and Achilles tendon tendinopathy as verified by ultrasound. The biopsies were stained using immunohistochemistry in order to delineate the innervation patterns in the structures involved in insertional Achilles tendinopathy. Immunohistochemical examinations found that the subcutaneous bursa scored the highest using a semi-quantitative evaluation of the degree of innervation when compared to the retrocalcaneal bursa, the Achilles tendon, and the calcaneal bone. These findings suggest that the subcutaneous bursa, which is traditionally not included in surgical treatment, may be a clinically important factor in insertional Achilles tendinopathy.

    Greater trochanteric pain syndrome (GTPS) is a pathology that can involve the trochanteric bursa or the tendons which attach to the greater trochanter. To clarify the potential importance of bursa versus tendon pathology and of substance P (SP) in contributing to pain in this condition tendon and bursa tissue biopsies were obtained from 34 patients with GTPS and 29 control subjects. Specimens were evaluated via light microscopy for histopathological and morphological differences, as well as using immunohistochemistry for macrophages (CD68), inflammatory cells (CD45) and SP. Bursa [stroma score, mean (SD): 4.18 (1.65) vs. 2.53 (1.61), p = 0.051] and tendon [Bonar score, mean (SD): GTPS mean (SD) 12.65 (2.0), control (10.43 (4.84), p = 0.04] from subjects with GTPS demonstrated more extensive signs of pathology than specimens from control subjects. There was a significantly greater presence of SP in the bursa (frequency: 9/12 vs. 6/16, p = 0.047), but not in the tendon (8/12 vs. 8/15, p = 0.484) of subjects with GTPS compared to controls. An increased presence of SP in the trochanteric bursa may be related to the pain associated with GTPS.

    The purpose of our study was to verify that increased widening of the anterior portion of the subacromial-subdeltoid bursa is associated with anteromedial shoulder pain. Bursography, sonography, and CT were performed in six cadaver shoulders and compared with anatomic sections in neutral position and while the humerus was extended and internally rotated. For the clinical study, the width of the anterior portion of the bursa was measured in both positions in both shoulders of 27 patients referred because of shoulder pain and in eight asymptomatic volunteers. Pain was coded as absent, experienced in the anteromedial portion of the shoulder, or experienced elsewhere but not anteromedially, and we compared the pain scores between shoulder positions. In all cadaver shoulders, when compared with CT scans and anatomic sections, sonography showed the morphology of the bursa, its relationships with surrounding structures, and morphologic changes associated with position. In volunteers, the mean width of the bursa was 0.74 +/- 0.05 and 0.93 +/- 0.09 mm (p = 0.013), respectively, in neutral and stress position. In patients, the same values were 0.70 +/- 0.07 and 0.81 +/- 0.14 mm (p = 0.286) in the asymptomatic side and 1.20 +/- 0.11 and 1.75 +/- 0.23 mm (p bursa was wider in patients experiencing pain anteromedially than in those who experienced pain elsewhere and volunteers (p = 0.002 and bursa was wider in symptomatic shoulders than in asymptomatic shoulders (p bursa is associated with anteromedial shoulder pain and the clinical syndrome of coracoid impingement.

    Navicular disease in the horse often requires injection of the navicular bursa. We have developed an ultrasound-guided, lateral needle approach to navicular bursocentesis, which avoids penetration of the deep digital flexor tendon (DDFT) and the need for radiographic control. To describe and evaluate the feasibility and efficacy of an ultrasound-guided, lateral bursocentesis technique. Cadaveric and in vivo experiments. The navicular bursa in 62 cadaveric forelimbs of 31 horses and in both forelimbs of 26 live horses, positioned with the foot flexed in a navicular block, were submitted to lateral, ultrasound-guided injection of 1.5 ml radiocontrast agent. Lateromedial radiographs were taken to locate the contrast. A second injection of 0.5 ml methylene blue was administered during needle withdrawal in cadaveric limbs to investigate the needle pathway during dissection. Contrast agent was successfully deposited in the navicular bursa in 104 of 114 (91%) limbs and in the navicular bursa alone in 89 of 114 (78%) limbs. Dissection showed no evidence of penetration of the DDFT in cadaver limbs. Failure to inject the navicular bursa was significantly associated with poor quality of the ultrasound image (P = 0.04) and resulted in aberrant injection of the distal interphalangeal joint in five of 114 (4%) limbs, the peribursal soft tissues in four of 114 (4%) limbs and the digital flexor tendon sheath in one of 114 (0.9%) limbs. Synovial fluid was observed at the needle hub in 58% of live horses. It is unknown whether injection results obtained in the limbs of horses without disease can be extrapolated to horses with clinical disease of the podotrochlear apparatus. The localisation of contrast medium on radiographs may not accurately reflect the behaviour of local anaesthetic solution or therapeutic medications injected in the navicular bursa. This lateral, ultrasound-guided technique for injecting the navicular bursa is effective, does not penetrate the DDFT and avoids

    Full Text Available Migration, which consists of quite complex components, is a concept subjected in many scientific research areas. Internal migration refers a migration occurred in the boundaries of a country. Migration in Turkey usually tends to be directed towards larger and more industrialized provinces. Nevertheless, there exists a density on the direction of certain provinces such as migration from Erzurum to Bursa. Nowadays, the proceeding of the migration flows between Erzurum and Bursa since 1980’s is another point which necessitates to be examined. The purpose of this study is to investigate the migration between Erzurum and Bursa by using compartment models in the 1980-2015 period. The paper performs compartment models to explain the changes of migration flows in terms of gross domestic product, unemployment rate, and time. According to the results, there is a significant increase in migration from Erzurum to Bursa depending on the time of migration and unemployment rate. Nonetheless, there is no significant change related with the gross domestic product. In addition, the study has shown that migration increases as unemployment rate decreases; but there is no significant change in migration depending on time and gross domestic product from Bursa to Erzurum.

    Frozen shoulder is a debilitating condition characterized by gradual loss of glenohumeral motion with chronic inflammation and capsular fibrosis. Yet its pathogenesis remains largely unknown. We hypothesized that the subacromial bursa may be responsible for the pathogenesis of frozen shoulder by producing inflammatory cytokines. We obtained joint capsules and subacromial bursae from 14 patients with idiopathic frozen shoulder and from 7 control subjects to determine the expression levels of interleukin (IL) 1α, IL-1β, IL-6, tumor necrosis factor α (TNF-α), cyclooxygenase (COX) 1, and COX-2 by real-time reverse transcriptase-polymerase chain reaction, immunohistochemistry, and enzyme-linked immunosorbent assay. IL-1α, IL-1β, TNF-α, COX-1, and COX-2 were expressed at significantly high levels in the joint capsules of the frozen shoulder group compared with those of the control group. Intriguingly, IL-1α, TNF-α, and COX-2 were also expressed at significantly high levels in the subacromial bursae of the frozen shoulder group compared with those of the control group. Immunohistochemical analysis showed increased expression of COX-2 in both the joint capsules and subacromial bursae of the frozen shoulder group. These findings imply that elevated levels of inflammatory cytokines in the subacromial bursa may be associated with the pathogenesis of inflammation evolving into fibrosis.

    Objective. As a therapeutic injection into the subacromial bursa (SAB) is commonly performed for impingement syndrome, it is important to know whether this fluid can be retained for a period of time and cause confusion with a pathologic collection of fluid. This study identifies and describes the appearance of recent subacromial injection using MR imaging, and the appearance of a potential complication.Design and patients. Fourteen asymptomatic shoulders were studied with MR imaging using fast spin echo T2-weighted imaging (1.5 T) prior to injection with 7 cm{sup 3} of xylocaine. Four shoulders had subacromial fluid and were eliminated from the study. The remaining 10 (9 men, 1 woman; age range 27-36 years, average age 33 years) were then re-imaged immediately, and at 6, 12 and 24 h after the injection or until fluid resolved. Each set of images was reviewed for the presence of fluid in the SAB and for additional abnormalities.Results. Fluid was identified in all subjects in the SAB in the immediate, 6 and 12 h post-injection images. At 24 h, fluid was not identified within the SAB in eight of 10 patients. In one patient fluid resolved in 48 h. The other continued to demonstrate fluid in the SAB and in the joint as well as abnormal signal in the infraspinatus muscle from a presumed myositis. Imaging was performed up to 10 days after the injection in this patient.Conclusions. It is known that fluid identified in the SAB without evidence of a cuff tear may be due to bursitis. However, if MR imaging is performed within 24 h of injection, the presence of the fluid may be iatrogenic. In addition, the history of recent therapeutic injection is very important as complications such as myositis can occur as a result of the injection. Knowledge of injection prior to imaging is vital for accurate interpretation of MR shoulder examinations. (orig.)

    Objective: To assess dynamic MRI with Gd-DTPA enhancement for evaluating inflammatory changes in the subacromial bursa. Design and patients: We detected the signal intensity changes in dynamic MRI of the subacromial bursa, and confirmed these macroscopically by arthroscopy and histologically. The signal intensity was measured using built-in software, and the enhancement ratio (E ratio) was calculated from dynamic MR images. In addition, as a parameter of the rate of the increase in the signal intensity from 0 to 80 s, the mean increase per second in the E ratio was obtained as the coefficient of enhancement (CE). The correlation was studied of the E ratio and CE with the arthroscopic findings (redness, villous formation, thickening and adhesion), and of the E ratio and CE with the histological findings (capillary proliferation, papillary hyperplasia, fibrosis and inflammatory cell infiltration) of the subacromial bursa. Of patients with shoulder pain, this study included those with rotator cuff injury; patients with rheumatoid arthritis or pitching shoulder disorders were excluded. There were 27 patients (15 men, 12 women) ranging in age from 25 to 73 years (mean 49.1 years). Dynamic MRI of the shoulder was also performed on the healthy side of 10 patients and in five normal young volunteers. Results and conclusions: Changes in signal intensity on dynamic MRI were measured in the subacromial bursa. The E ratio (80 s) and CE (0-80 s) were significantly correlated with redness and villous formation as arthroscopic findings, positively correlated with capillary proliferation and papillary hyperplasia as histological findings (p < 0.05), and negatively correlated with fibrosis as a histological finding (p < 0.05) in the subacromial bursa. The patterns of dynamic curves were well correlated with the bursoscopic and histological findings of the synovium of the subacromial bursa. Dynamic MRI appears to correlate with inflammatory activity of synovium of the subacromial

    Synovitis of the navicular bursa is common in performance horses. The objective of this study was to describe an ultrasound-guided technique to inject a distended navicular bursa and to evaluate its feasibility for use by a clinician not trained in the technique. Twenty distal limbs of horses of various breeds and sizes were used. To produce synovial distension, the navicular bursa of each limb was injected with contrast medium using a lateral approach and radiography was performed to confirm that the contrast medium was distending the bursa. The digit was positioned with the distal interphalangeal joint in hyperextension. A microconvex ultrasound probe was placed in the hollow of the pastern, palmar to the middle phalanx and the region was assessed in a transverse plane slightly oblique to the horizontal plane. The ultrasound probe was rotated to visualize both the lateral and medial recesses and to select which side was more distended to inject. A 21G 0.8 × 50 mm needle was inserted abaxially to the probe in the plane of the ultrasound beam into the proximal recess of this navicular bursa and a methylene blue solution was injected. Following injection, dissection was performed to assess whether the navicular bursa had been successfully injected. This ultrasound-guided technique was reliably performed with a success rate of 68%. The success of injection is influenced by hyperextension of the foot, quality of ultrasound images and degree of distension of the bursa. © 2015 Blackwell Verlag GmbH.

    Complete olecranon bursectomy with debridement, protection of veins and nerves. Risk-adapted antibiotic therapy and early functional aftercare. Acute, traumatic laceration of the bursa olecrani, chronic therapy-resistant bursitis olecrani. For traumatic bursa injuries: general contraindications for anesthesia and surgery; chronic bursitis: initially not closable skin defect (plastic surgery required), hemodynamically instable patient (e.g. systemic inflammatory response syndrome [SIRS] or sepsis), pre-existing skin infection. Local anesthesia beyond the lesion, careful debridement, identification and removal of the entire bursa, excision of contaminated skin, lavage, drain insertion (Redon, Easy-flow, Penrose). Wound closure, elastic bandage, and splint. Elastic bandage for 2 days, followed by drain removal. Wound assessment, early functional aftercare without splint, antibiotic therapy in septic bursitis for 2 weeks, PRICE scheme. Removal of stitches after 10-12 days. Over 5 years, 138 cases of traumatic bursa lesion or chronic bursitis olecrani were treated in our clinic, 82 patients underwent surgery. Ten patients were treated with vacuum-assisted closure therapy and consecutive wound healing; fistulae occurred in two patients and in another two dehiscence developed. All of the defects could be closed without flaps.

    Lipoma arborescens arising in the extra-articular bursa of the knee joint is extremely rare. We describe an 11-year-old boy who complained of a gradual swelling mass of the lateral knee joint. Magnetic resonance imaging (MRI) showed a high signal intensity tumor on T1- and T2-weighted images with a thickened septa and nodular lesion that showed low signal intensity. The radiologist suggested the possible differential diagnosis of well-differentiated liposarcoma. At operation, the tumor was found under the iliotibial tract and was not in contact with the knee joint. Histopathologically, this lesion was diagnosed as lipoma arborescens arising in the extra-articular bursa of the knee joint. On MRI, the appearance of lipoma arborescens arising in the extra-articular bursa of the knee joint differed from that of conventional intra-articular lipoma arborescens. In this report, we describe a case of extra-articular lipoma arborescens of the knee joint bursa and discuss the diagnosis and etiology. PMID:27382924

    Unlike calcification, ossification is infrequent in the rotator cuff. We describe the clinical, radiographic, and pathologic findings in 64-year-old man with an ossified mass arising from a calcified portion of the rotator cuff tendon within the subacromial bursa. Mechanical stress and ischemic events are possible causes of cartilage formation followed by endochondral ossification, producing a mass causing outlet impingement.

    Full Text Available Abstract Results obtained in studies can contribute to the advancement of science and innovative methods and techniques for developing practical activities. Reporting conditions that may restrict the implementation of research is critical to ensure the optimal development of further technical studies. The objective of this study was to assess the walking stability of R. dominica on a flat and smooth surface. The study was based on the determination of mortality, morphology and walking stability of the insect outside the grain mass, on a flat and smooth surface. Mortality of adults of this Coleoptera in conditions with and without food was similar, which explains the difficulty that this insect had for accessing the food source on the flat and smooth surface. The measurements of body length (BOL, width (BOW and height (BOH of R. dominica were compared with those of Tribolium castaneum (Coleoptera: Tenebrionidae, which showed good ability to walk in these conditions. This study indicated that the former presents lower BOL and BOW, and greater BOH than the second, and all these variables showed differences when analyzed simultaneously by means of the construction of multivariate morphometric indices (Width × Height, Length × Height and Height × Length × Width. These morphometric variables, together with the definition of the geometry most similar to the body shape, resulted in determination of the center of gravity (CG and static rollover threshold (SRTgeom for both species. Rhyzopertha dominica and T. castaneum presented CGs considered high and low, respectively, and together with the values obtained for SRTgeom, may justify that R. dominica can be considered a less stable species during movement, and presents greater risk of rollover on flat and smooth surfaces.

    The discharge of heavy metals into the natural waters has numerous obvious impacts on physical, chemical and biological parameters of aquatic ecosystem. Bioassay tests are important steps in establishing appropriate water quality criteria and standards for diverse use of ponds, lakes, streams and river waters. Therefore, the acute toxicities of various heavy metals to water flea Daphnia magna, and snail Lymnaea acuminata, and toad tadpoles Bufo mentanostictus have been reported from the authors' laboratory. Chironomid larvae might be particularly useful as indicators of water quality because they are widely distributed in freshwater systems and often from diverse communities within particular habitat. The aim of this study was to determine the acute toxicity of ten heavy metals to the midge larvae Chironomus tentans Fabricius, which forms an important link in aquatic food chain(s).

    Degeneration of the rotator cuff is often associated with inflammation of the subacromial bursa and focal mineralization of the supraspinatus tendon. Portions of the supraspinatus tendon distant from the insertion site could transform into fibrous cartilage, causing rotator-cuff tears owing to mechanical instability. Indirect evidence is presented to link this pathology to ectopic production and secretion of bioactive bone morphogenetic proteins (BMPs) from sites within the subacromial bursa. Surgically removed specimens of subacromial bursa tissue from patients with chronic tears of the rotator cuff were analyzed by immunohistochemistry and reverse transcription-PCR. Bioactive BMP was detected in bursa extracts by a bioassay based on induction of alkaline phosphatase in the osteogenic/myogenic cell line C2C12. Topical and differential expression of BMP-2/4 and BMP-7 mRNA and protein was found in bursa tissue. The bioassay of C2C12 cells revealed amounts of active BMP high enough to induce osteogenic cell types, and blocking BMP with specific antibodies or soluble BMP receptors Alk-3 and Alk-6 abolished the inductive properties of the extract. Sufficient information was gathered to explain how ectopic expression of BMP might induce tissue transformation into ectopic bone/cartilage and, therefore, promote structural degeneration of the rotator cuff. Early surgical removal of the subacromial bursa might present an option to interrupt disease progression.

    In order to determine whether adhesion of the subacromial bursa leads to impingement, we measured the subacromial contact pressures before and after release of adhesion of this bursa. 18 shoulders with cuff tears and adhesion of the subacromial bursa were evaluated in 8 male and 10 female patients, of mean age 62 (53-71) years and who had no particular limitation of shoulder motion. We recorded subacromial pressures using a very sensitive film inserted under the acromion during surgery. In passive scapular plane elevation (scaption) at 100 degrees, the mean subacromial contact pressure and area declined from 1.43 (SD 0.23) MPa before release to 1.14 (SD 0.35) MPa after release (p bursa increases impingement between the acromion and the insertion of rotator cuff tendons.

    Artificial diets prepared with wheat germ, soybean protein, dextrosol, potato starch, sucrose, cellulose, soybean or sunflower oil, and vitamin solution for rearing Nezara viridula (L.) and Euschistus heros (Fabricius) were tested under controlled temperature (25 {+-} 1 deg C), RH (60 {+-} 10%), and photophase (14h). Three diets were tested and compared with the natural diet privet [soybean and peanut seeds and privet Ligustrum lucidum Ait. fruit (Oleaceae)]. All three artificial diets allowed full development. The diet containing sunflower oil was the most suitable for N. viridula while E. heros developed better on a diet composed of soybean oil. Data indicated that the artificial diets were inferior to the natural diet. The artificial diets were more adequate for E. heros. (author)

    To compare the practicability, visualization of structures, and iatrogenic damage of direct and transthecal approaches to the navicular bursa for diagnostic needle endoscopy. Descriptive study. Equine cadaver forelimbs (n = 30). Direct and transthecal approaches for insertion of a needle endoscope into the navicular bursa were performed. Video recordings of endoscopic procedures were assessed to determine all structures visualized within the navicular bursa. Number of attempts to gain access to the navicular bursa and total time for insertion and examination were recorded. Distribution and severity of iatrogenic lesions were assessed and scored after dissection. There were no statistical differences for number of attempts or time needed for insertion and examination between direct and transthecal approaches. The direct approach offered significantly increased visibility of the ipsilateral abaxial and proximal margins of the navicular bone, and ipsilateral collateral sesamoidean ligament. Iatrogenic lesions were superficial and focal, regardless of approach taken, or whether a blunt or sharp trocar tip was used. The direct approach provided significantly better visualization of the ipsilateral structures within the navicular bursa compared to the transthecal approach. Needle endoscopy offers a reliable technique to evaluate the navicular bursa and may complement or replace other diagnostic modalities in horses with lameness localized to the navicular region. © Copyright 2015 by The American College of Veterinary Surgeons.

    To evaluate a possible association of shoulder pain with the clinical features and the histopathological changes occurring in the ruptured tendon and subacromial bursa of patients with rotator cuff tear. One hundred and eighty patients were clinically evaluated with the constant score and the visual analogue pain scale. Radiographs and MRI were performed. The chronology of the rupture, the muscle fatty degeneration according to Goutallier's scale and the tear size were evaluated. For each patient, a biopsy of the supraspinatus tendon and subacromial bursa was performed during arthroscopic rotator cuff tear repair and the specimens were histopathologically analysed. Clinically, the shoulder was more painful in females, in the presence of a chronic cuff lesion and a low Goutallier's grade (P bursa were directly associated with pain (P bursa compared with those in the rotator cuff. Considering that the bursa plays also an essential role during the healing process, this "new" role of the subacromial bursa as pain generator has important repercussions in both pharmacological and surgical treatments of rotator cuff tears.

    Several viruses of the family of Adenoviridae are associated with disease in birds. Here we report the detection of a novel adenovirus in the cloacal bursa of herring gulls (Larus argentatus) and lesser black-backed gulls (Larus fuscus) that were found dead in the Netherlands in 2001. Histopathological analysis of the cloacal bursa revealed cytomegaly and karyomegaly with basophilic intranuclear inclusions typical for adenovirus infection. The presence of an adenovirus was confirmed by electron microscopy. By random PCR in combination with deep sequencing, sequences were detected that had the best hit with known adenoviruses. Phylogenetic analysis of complete coding sequences of the hexon, penton and polymerase genes indicates that this novel virus, tentatively named Gull adenovirus, belongs to the genus Aviadenovirus. The present study demonstrates that birds of the Laridae family are infected by family-specific adenoviruses that differ from known adenoviruses in other bird species. - Highlights: ► Lesions typical for adenovirus infection detected in cloacal bursa of dead gulls. ► Confirmation of adenovirus infection by electron microscopy and deep sequencing. ► Sequence analysis indicates that it is a novel adenovirus in the genus Aviadenovirus. ► The novel (Gull) adenovirus was detected in multiple organs of two species of gulls.

    Full Text Available Lantana camara L. is a widespread plant species mostly native to subtropical and tropical regions of the world. In this study, insecticidal and repellent activities of L. camara essential oil were evaluated against Callosobruchus maculatus (Fabricius (Col: Bruchidae. Analysis of chemical composition by gas chromatography/mass spectrometry (GC/MS showed high amounts of sesquiterpenes, mainly α-humelene (23.3% and cis-caryophyllene (16.2%. The results showed that the essential oil of L. camara has strong repellent activity against adults of C. maculatus at all tested concentrations. After 2 and 4 h, 97.4 and 100% repellency was seen at highest concentrations of 0.4 μL cm-2, respectively. Moreover, the oil was found to be toxic to adults when applied by fumigation. Responses varied with the gender of insect and exposure time. The LC50 values were 282.7 and 187.9 μL L-1 for females and males, respectively. An increase in the exposure time from 3 to 24 h caused increasing in mortality from 23.6 to 100% in males and from 14.1 to 97.1% in females, at highest concentration (1160 μL L-1. According to these results, L. camara essential oil may be useful as an alternative for bean protection against C. maculatus.Lantana camara L. es una especie vegetal nativa de las regiones subtropicales y tropicales del mundo.

    Objective To investigate the additive effect of sono-guided subacromial bursa injection of hyaluronate with steroid in patients with peri-articular shoulder disorders. Method This prospective randomized controlled trial involved 26 patients who had shoulder pain. Group A, consisting of 13 patients, was treated with a sono-guided subacromial bursa injection containing a mixture of 0.5% lidocaine (5 ml) and triamcinolone 40 mg (1 ml), followed by injection with sodium hyaluronate (2 ml) once a week for 3 weeks. The other 13 patients (Group B) were treated with a sono-guided subacromial bursa injection containing a mixture of 0.5% lidocaine (5 ml) and triamcinolone 40 mg (1 ml) once a week for 3 weeks. The effects were assessed using a visual analogue scale (VAS) of shoulder pain, active range of motion (AROM), shoulder function assessment scale (SFA), shoulder disability questionnaire (SDQ) at study entry and every week from first injection until 4 weeks after the 1st injection (= 2 weeks after 3rd injection). Results (1) Demographic features and all parameters measured before injection did not show a significant difference between the 2 groups. (2) Statistically significant improvements were shown in VAS, SFA, SDQ during the 1st, 2nd, and 4th week after the first injection in both groups (pbursa injection of hyaluronate with steroid in patients with peri-articular shoulder disorders has additive effects on functional improvement of the affected shoulder, including the AROM of internal rotation.

    After the 1999 Golcuk Mw=7.4, the seismic stress of the North Anatolian Fault has been transferred onto the segments in the Marmara Sea. The NAF is separated to three branches around the Marmara region; one branch runs into the Marmara Sea from the Yalova-Cinarcik location in the north, the second branch runs into the Marmara Sea from the Gemlik location in the south, and the last one goes toward the Bursa basin from the Sakarya-Pamukova location in the lower south. Some researchers consider that the south branch, which experienced the last major earthquake in the year 1064, poses a danger as much as the north branch.For that reason, this study has been conducted for monitoring the fault activities around the Bursa basin. In this respect, the four Palsar data having the best baseline condition have been obtained between the years 2007-2010. The processing of these data have been resulted in significant deformation interferograms for the data pairs of 31st Oct 2007-8th May 2010 and 31st Jan. 2008-24th Dec. 2010. There are seen deformation anomalies in the Bursa basin along 33 km long in E-W direction and 4.5 km long in N-S direction. The shape of the deformation fringes points out that there is a right lateral strike slip fault line passing through the Bursa basin. The geomorphologic characteristics in the region make us think this fault line may connect to the Sakarya-Geyve branch of the North Anatolian Fault system. The maximum amount of the deformation around the fault line has been determined 18 cm in three years. This amount is too much in comparison to 2.2 cm/yr slip rate of the NAF. As the deformation anomalies are investigated in detail a contraction draws attention, overlapping with a right lateral strike slip motion. Consequently, it can precociously be sad that there exits an uplifting combining with the lateral motion. In addition, significant deformation anomalies have been detected on the Gemlik location where the Iznik fault segment reaches the

    Full Text Available The presence of nanoparticles on the body of the honeybee Apis dorsata Fabricius, was investigated for the first time to better understand the bee’s behaviour. These have been observed by using Scanning Electron Microscopy (SEM, Transmission Electron Microscopy (TEM and confirmed by Atomic Force Microscopy (AFM. Our study clearly denotes that the Indian rock honey bee Apis dorsata possess calcium silicate and calcium phosphate nanoparticles on its body surface of 5-50 nm in diameter. In particular, the nanoparticles on the abdomen and thorax of A. dorsata have an average diameter of about 10 nanometers and they are smaller than those found on wings of the same bees which are about 20 nanometers. The nanoparticles found are different of the ones previously observed on honey bees or other insects. The origin and role of these natural nanoparticles on the body of the Indian rock bee need to be to be further investigated; more research in the subject might raise important aspects in relation to the conservation of these unique pollinators.

    Full Text Available Energetic cost of digging behavior in workers of the leaf-cutting ant Atta sexdens (Fabricius. During nest excavation, leaf-cutting ant workers undergo reduction in their body reserve, particularly carbohydrates. In order to estimate the energetic cost of digging, groups of 30 workers of the leaf-cutting ant Atta sexdens were sealed in a hermetic chamber for 24, 48 and 72 hours, with and without soil for digging, and had the CO2 concentration measured using respirometric chambers as well as volume of soil excavated (g. As expected, the worker groups that carried out soil excavation expelled more carbon dioxide than the groups that did not excavate. Therefore, a worker with body mass of 9.65 ± 1.50 mg dug in average 0.85 ± 0.27 g of soil for 24 hours, consuming ca. 0.58 ± 0.23 J. In this study, we calculate that the energetic cost of excavation per worker per day in the experimental set-up was ca. 0.58 J.

    The life history traits of blow fly Cochliomyia macellaria (Fabricius, 1775) was studied under semi-controlled laboratory conditions at 29.14°C temperature, 72.53% relative humidity, and 12-h photoperiod. The raw data were analyzed based on the age-stage, two-sex life table, considering the development rates among individuals of both sexes. Cochliomyia macellaria survival rate was 0.43 (♂) and 0.40 (♀), while life expectancy was 17.9 (♂) and 20.9 (♀) days, for adult males and females, respectively. The total fecundity was 681.15 eggs/female, with an average of 3.65 batches/female and 199 eggs/batch. The intrinsic rate of increase (r) was 0.327 days-1, the finite rate of population increase (λ) was 3.35 days-1, the mean generation time (T) was 17.15 days, and the net reproduction rate (R 0 ) was 272.46 offspring/individual. The population parameters found here corroborates that C. macellaria population act as a r selected species under laboratory conditions. Additionally, development data and accumulated degree days (ADD) for each stage of C. macellaria are provided and its implications for the forensic use are discussed.

    The orb-weaving spider genus Gasteracantha Sundevall, 1833 (Araneidae) is notable for its pronounced sexual size dimorphism. Gasteracantha females are characterized by having a highly sclerotized "spiny" abdomen varying in relative size and number of spines, as well as abdomen dorsally and ventrally provided with varying numbers of sigillae (Cambridge 1879). The genus currently includes 70 described species and 31 subspecies (World Spider Catalog 2014). The Oriental species Gasteracantha geminata (Fabricius, 1798) was originally described from Ramnad (now known as Ramanathapuram) in Tamilnadu State of Southern India based on an unspecified number of female specimen(s). The female of this species has been described and illustrated several times by various authors. Its male is only known from the description of Simon (1895). Simon's original description of the male of G. geminata was supported by two simple but beautiful and informative illustrations: a retrolateral view of the cephalothorax and a dorsal view of the abdomen (Simon 1895, figs. 886, 887). However we lack a clear and detailed description of the male genitalia. The present paper provides detailed redescription of G. geminata and illustrations of the male pedipalp.

    Plants respond to cold stress by modulating biochemical pathways and array of molecular events. Plant morphology is also affected by the onset of cold conditions culminating at repression in growth as well as yield reduction. As a preventive measure, cascades of complex signal transduction pathways are employed that permit plants to endure freezing or chilling periods. The signaling pathways and related events are regulated by the plant hormonal activity. Recent investigations have provided a prospective understanding about plant response to cold stress by means of developmental pathways e.g., moderate growth involved in cold tolerance. Cold acclimation assays and bioinformatics analyses have revealed the role of potential transcription factors and expression of genes like CBF, COR in response to low temperature stress. Capsella bursa-pastoris is a considerable model plant system for evolutionary and developmental studies. On different occasions it has been proved that C. bursa-pastoris is more capable of tolerating cold than A. thaliana. But, the mechanism for enhanced low or freezing temperature tolerance is still not clear and demands intensive research. Additionally, identification and validation of cold responsive genes in this candidate plant species is imperative for plant stress physiology and molecular breeding studies to improve cold tolerance in crops. We have analyzed the role of different genes and hormones in regulating plant cold resistance with special reference to C. bursa-pastoris. Review of collected data displays potential ability of Capsella as model plant for improvement in cold stress regulation. Information is summarized on cold stress signaling by hormonal control which highlights the substantial achievements and designate gaps that still happen in our understanding. PMID:28855910

    This paper studies the Ornstein-Uhlenbeck model that incorporates long memory stochastic volatility which is known as fractional Ornstein-Uhlenbeck model. The determination of the existence of long range dependence of the index prices of FTSE Bursa Malaysia KLCI is measured by the Hurst exponent. The empirical distribution of unobserved volatility is estimated using the particle filtering method. The performance between fractional Ornstein -Uhlenbeck and standard Ornstein -Uhlenbeck process had been compared. The mean square errors of the fractional Ornstein-Uhlenbeck model indicated that the model describes index prices better than the standard Ornstein-Uhlenbeck process.

    Full Text Available The first appearance, distribution and frequency of immunoglobulins (Igs-positive lymphocytes were investigated in the lymphoid organs of native chicken’s embryos from embryonic day (ED 8 to ED 20. The tissues from the lymphoid organs were dehydrated in alcohol, cleared in xylene, embedded in different grades of paraffin and 6-micron thick sections were immunostained by the indirect immunoperoxidase method using antichicken immunoglobulins. IgM-positive lymphocytes were first identified in the follicles of bursa of Fabricius at ED 10, in the white pulp of the spleen at ED 14 and in the lamina propria of the cecal tonsil at ED 20. Their frequencies of populations were statistically significant from ED 14 to ED 20. IgG-positive lymphocytes were first appeared in the bursa of Fabricius and spleen at ED 20. In the bursa IgG-positive lymphocytes were located in the medulla and cortical part of the follicles, whereas, in the spleen these immune cells were located around the white pulp. IgA-positive lymphocytes were not observed in any of the developing lymphoid organs of the present study. When the data for bursa of Fabricius, spleen, thymus and cecal tonsil were statistically compared, it was observed that both IgM- and IgG-positive lymphocytes were significantly higher in bursa of Fabricius.

    Synovial osteochondromatosis is a rare disease characterized by cartilaginous and osseous metaplasia of the joint synovium. While it may affect practically any synovial joint, the knee is most often affected. An imperforate suprapatellar plica is also a rare finding in the knee. We report an exceptionally rare case of synovial osteochondromatosis of the knee characterized by isolated multiple loose bodies in the suprapatellar bursa caused by imperforate suprapatellar plica in a 52-year-old woman. The case was successfully treated by arthroscopic surgery. A worse-case scenario and possible diagnostic and therapeutic challenges are discussed.

    Traditional portfolio optimization methods in the likes of Markowitz' mean-variance model and semi-variance model utilize static expected return and volatility risk from historical data to generate an optimal portfolio. The optimal portfolio may not truly be optimal in reality due to the fact that maximum and minimum values from the data may largely influence the expected return and volatility risk values. This paper considers distributions of assets' return and volatility risk to determine a more realistic optimized portfolio. For illustration purposes, the sectorial indices data in FTSE Bursa Malaysia is employed. The results show that stochastic optimization provides more stable information ratio.

    Black and Scholes option pricing model is one of the most recognized stochastic differential equation model in mathematical finance. Two parameter estimation methods have been utilized for the Geometric Brownian model (GBM); historical and discrete method. The historical method is a statistical method which uses the property of independence and normality logarithmic return, giving out the simplest parameter estimation. Meanwhile, discrete method considers the function of density of transition from the process of diffusion normal log which has been derived from maximum likelihood method. These two methods are used to find the parameter estimates samples of Malaysians Gold Share Price data such as: Financial Times and Stock Exchange (FTSE) Bursa Malaysia Emas, and Financial Times and Stock Exchange (FTSE) Bursa Malaysia Emas Shariah. Modelling of gold share price is essential since fluctuation of gold affects worldwide economy nowadays, including Malaysia. It is found that discrete method gives the best parameter estimates than historical method due to the smallest Root Mean Square Error (RMSE) value.

    Forensic entomologists rely on published developmental datasets to estimate the age of insects developing on human remains. Currently, these datasets only represent populations of targeted insects from specific locations. However, recent data indicate that populations can exhibit genetic variation in their development, including signatures of local adaptation demonstrated by regionally distinct plastic responses to their environments. In this study, three geographically distinct populations of the secondary screwworm, Cochliomyia macellaria Fabricius (Diptera: Calliphoridae; College Station, Longview, and San Marcos, TX, USA), a common blow fly collected from human remains in the southern USA, were reared in two distinct environments (cool 21 °C, 65 % relative humidity (RH); and warm 31 °C, 70 % RH) over 2 years (2011 and 2012) in order to determine differences in development time and mass. Significant differences in immature and pupal development time, as well as pupal mass, were shown to exist among strains derived from different populations and years. For immature development times, there was evidence of only an environmental effect on phenotype, while genotype by environment interactions was observed in pupal development times and pupal mass. College Station and San Marcos populations exhibited faster pupal development and smaller pupal sizes in the cooler environment relative to the Longview population, but showed an opposite trend in the warm environment. Rank order for College Station and Longview populations was reversed across years. Failure to take genetic variation into consideration when making such estimates can lead to unanticipated error and bias. These results indicate that genetics will have little impact on error when working with Texas genotypes of C. macellaria at ~30 °C and 70 % RH, but will have a more meaningful impact on error in postmortem interval estimates with this species in cooler, drier environments.

    The retro-calcaneal bursa presents a synovial and a non-synovial osseous part of variable dimensions. Studies objectively measuring the variability of the size of this osseous bursal surface cannot be found in literature. The objective of this study was to investigate (i) the dimension variability of the bony part of the bursa and (ii) the relationship of this surface to other articulating areas of the calcaneus. A digital planimeter was used to measure the bursae (n=86) and other articular surface areas of the calcaneus and statistically compared with ANOVA and correlation estimations. The osseous area measured 1.12 (±0.55) cm2, with only the superior articulating area demonstrating a weak correlation to this osseous surface. The osseous area presents a weak correlation with the axial articulating area of the calcaneus. Information on the size of the bony bursa may help safe excision of retrocalcaneal exostoses and in Achille's tendon repair around the posterior tuberosity. Copyright © 2017 Elsevier Ltd.

    To determine whether triamcinolone acetonide diffuses from the distal interphalangeal joint (DIPJ) to the navicular bursa, diffusion is direct or systemic, and addition of sodium hyaluronan has an effect on diffusion in horses. 11 adult horses without forelimb lameness. 1 randomly chosen forelimb DIPJ of each horse received an injection of 10 mg of triamcinolone acetonide plus 20 mg of sodium hyaluronan (group 1), and the contralateral forelimb DIPJ received an injection of 10 mg of triamcinolone acetonide plus 2 mL of lactated Ringer's solution (group 2). Synovial fluid samples were taken from both forelimb navicular bursae and 1 hind limb navicular bursa (systemic control group) at 6 hours. Triamcinolone acetonide concentrations in synovial fluid were quantified by use of high-performance liquid chromatography plus tandem mass spectrometry. Data were logarithmically transformed, and contrast analysis was performed on the 3 groups. Triamcinolone acetonide was detected in navicular bursal samples in all groups. Groups 1 and 2 had significantly greater concentrations of triamcinolone acetonide than the systemic control group. There was no significant difference between groups 1 and 2. Triamcinolone acetonide diffused directly from the DIPJ into the navicular bursa in clinically normal horses, and diffusion was not affected by addition of hyaluronan. Injection into the DIPJ with triamcinolone acetonide or a triamcinolone acetonide-hyaluronan combination can potentially be used for treatment of navicular syndrome, but further studies are needed to determine whether triamcinolone acetonide diffuses similarly in horses with navicular syndrome.

    In chickens, a single set of unique functional segments of both Ig H and L chain genes is rearranged during early embryogenesis to generate a pool of B cell progenitors that will be diversified in the bursa by gene conversion, forming the preimmune repertoire. After hatching, bursal cells are exposed to environmental Ags in the bursal lumen. We prepared B cells from each single bursal follicle and used PCR-directed Ig L chain gene analysis to study the differentiation of B cells and the effect of antigenic stimulation from the bursal lumen on the neonatal chicken B cell repertoire formation. Selective amplification of B cell clones with a productive V-J joint was observed during the late embryonic stage, possibly by the interaction with ligands expressed on the bursal stroma and further accelerated in the neonatal chicken. Administration of the artificial Ags into the bursal lumen before the isolation of bursa by bursal duct ligation in the embryo caused a significant increase in lymphocytes with a productive V-J joint in the neonatal chicken bursa compared with the isolated bursa. Intra- and interclonal diversity of a complementarity-determining region measured by an evolutionary distance increased during bursal development. Clonal diversification did not require stimulation by artificial Ags from the bursal lumen. Thus, the preimmune repertoire in the bursa is generated by gene conversion during Ag-independent B cell proliferation, and antigenic stimulation from the bursal epithelium to bursal B cells plays roles in the selection of clones with a productive V-J joint.

    Navicular bursa (NB) centesis is a common diagnostic and therapeutic procedure in equine practice. This case report documents the clinical, diagnostic imaging and histological findings in a horse with a suspected iatrogenic deep digital flexor tendon (DDFT) injury following centesis of the NB via a modified distal plantar approach (placement of two needles in a weight bearing position). Although it cannot be proven with absolute certainty, the authors believe that this is the first reported case where NB centesis is the likely cause of a DDFT lesion, and with magnetic resonance imaging performed both pre- and post-centesis. With this potential, though rare, complication of the procedure, alternative tendon sparing injection techniques should be considered prior to NB centesis in certain cases. PMID:29085826

    A temporary earthquake station network of 11 seismological recorders was operated in the Bursa region, south of the Marmara Sea in the northwest of Turkey, which is located at the southern strand of the North Anatolian Fault Zone (NAFZ). We located 384 earthquakes out of a total of 582 recorded events that span the study area between 28.50-30.00°E longitudes and 39.75-40.75°N latitudes. The depth of most events was found to be less than 29 km, and the magnitude interval ranges were between 0.3 ≤ ML ≤ 5.4, with RMS less than or equal to 0.2. Seismic activities were concentrated southeast of Uludag Mountain (UM), in the Kestel-Igdir area and along the Gemlik Fault (GF). In the study, we computed 10 focal mechanisms from temporary and permanents networks. The predominant feature of the computed focal mechanisms is the relatively widespread near horizontal northwest-southeast (NW-SE) T-axis orientation. These fault planes have been used to obtain the orientation and shape factor (R, magnitude stress ratio) of the principal stress tensors (σ1, σ2, σ3). The resulting stress tensors reveal σ1 closer to the vertical (oriented NE-SW) and σ2, σ3 horizontal with R = 0.5. These results confirm that Bursa and its vicinity could be defined by an extensional regime showing a primarily normal to oblique-slip motion character. It differs from what might be expected from the stress tensor inversion for the NAFZ. Different fault patterns related to structural heterogeneity from the north to the south in the study area caused a change in the stress regime from strike-slip to normal faulting.

    To report a case of scapular osteochondroma associated with pain and winging that is rarely reported in the medical literature. A 19-year-old male presented with pain and winging of the right scapula. CT scan revealed an osteochondroma of the medial border of the scapula with a large bursa between the chest wall and the tumour. Excision of the tumour relieved the symptoms. Pathological study showed osteochondroma of the scapula. In a follow-up 1 year later he was free of pain with no clinical or radiological sign of recurrence. A case of scapular osteochondroma associated with pain and winging treated by excision and follow-up showed no sign of clinical or radiological recurrence.

    The purpose of this study was to compare sonographic evaluations of patients referred with suspected snapping of their iliopsoas tendon with the pain relief achieved from anesthetic injection of the iliopsoas bursa, and with the subsequent surgical outcome. This study also assessed the effectiveness of Kenalog injection into the iliopsoas bursa for long-term pain relief. Dynamic and static sonography was performed in 40 patients with clinically diagnosed snapping hips. The iliopsoas bursa was injected with Bupivicaine and Lidocaine in the first 22 patients, and an additional 1 ml Kenalog-40 was added to this mixture in the last 18 patients. We compared the static and dynamic sonographic findings with change in the patients' level of pain at 2 days after anesthetic injection. The sonographic findings and response to anesthetic injection were also compared to the response to Kenalog injection and the results of any subsequent surgery. Static sonography of the iliopsoas tendon was normal in 38 patients, and detected iliopsoas bursitis in one patient and iliopsoas tendinopathy in another. Snapping of the iliopsoas tendon was observed using dynamic sonography in 9 of the 40 patients. Following anesthetic injection of the iliopsoas bursa, 29 patients had complete or partial pain relief, and 11 patients had no pain relief. Eight of the nine patients with a snapping iliopsoas tendon had complete or partial pain relief from the bursal injection. Twelve of the 29 patients with pain relief after anesthetic injection later had an arthroscopic iliopsoas tendon release, and all of these 12 patients had a good postoperative result. Of the 18 patients who had Kenalog-40 injected into the iliopsoas bursa and did not have iliopsoas surgery, 16 had sustained pain relief following the injection. Patients with groin pain and a clinically suspected snapping iliopsoas tendon can benefit from injection into the iliopsoas bursa even if the snapping tendon is not visualized sonographically

    Transposon mutagenesis is a genetic process that involves the random insertion of transposons into a genome resulting in the disruption of function of the genes in which they insert. Identification of the insertion sites through DNA sequencing allows for the identification of the genes disrupted and the creation of "libraries" containing a collection of mutants in which a large number of the nonessential genes have been disrupted. These mutant libraries have been a great resource for investigators to understand the various biological functions of individual genes, including those involved in metabolism, antibiotic susceptibility, and pathogenesis. Here, we describe the detailed methodologies for constructing a sequence defined transposon mutant library in both Staphylococcus aureus and S. epidermidis using the mariner-based transposon, bursa aurealis.

    2015-01-01

    Synovial chondromatosis is an uncommon condition, and involvement of the shoulder is even more rare. We report on a 39-year-old female who presented with symptoms, radiographic features, and intraoperative findings consistent with multiple subacromial loose bodies resulting in a partial-thickness, bursal-sided rotator cuff tear of the supraspinatus muscle. She was treated with an arthroscopic removal of loose bodies, complete excision of the subacromial/subdeltoid bursa, acromioplasty, and rotator cuff repair. To our knowledge, this is the first report of arthroscopic treatment for a bursal-sided, partial-thickness rotator cuff tear treated with greater than two-year clinical and radiographic follow-up. We utilized shoulder scores, preoperative and postoperative range of motion, and imaging to assess the results of treatment and surveillance for recurrence in our patient after two-year follow-up.

  17. Black-Scholes finite difference modeling in forecasting of call warrant prices in Bursa Malaysia

    2014-07-01

    Call warrant is a type of structured warrant in Bursa Malaysia. It gives the holder the right to buy the underlying share at a specified price within a limited period of time. The issuer of the structured warrants usually uses European style to exercise the call warrant on the maturity date. Warrant is very similar to an option. Usually, practitioners of the financial field use Black-Scholes model to value the option. The Black-Scholes equation is hard to solve analytically. Therefore the finite difference approach is applied to approximate the value of the call warrant prices. The central in time and central in space scheme is produced to approximate the value of the call warrant prices. It allows the warrant holder to forecast the value of the call warrant prices before the expiry date.

    Objective Although shoulder pain is often associated with rotator cuff tears, many tears are asymptomatic and are not the cause of the patient's pain. This may explain the persistence of symptoms in some patients despite technically successful rotator cuff repair. It has been proposed that rotator cuff tears cause pain through subdeltoid/subacromial bursal inflammation. The aim of this study was to determine whether bursal inflammation seen on MRI is associated with pain in patients with rotator cuff tears of the shoulder. Methods The shoulders of 255 patients were screened with ultrasound. 33 full-thickness rotator cuff tears (18 with shoulder pain and 15 without pain) were identified and subsequently studied using contrast-enhanced MRI of the shoulder. Enhancement of the subacromial bursa was scored independently by two musculoskeletal radiologists. Logistic regression was used to determine whether bursal enhancement was independently associated with pain. Results There was a significant association between pain and age, with greater likelihood of pain in younger patients. Bursal enhancement was common in both painful and painless tears. No statistically significant link between pain and bursal enhancement was seen, even after accounting for age. Conclusion Although enhancement of the subdeltoid/subacromial bursa was common, no evidence was found to support the hypothesis that bursal enhancement is associated with pain in rotator cuff tears. It is therefore unlikely to determine reliably which patients would benefit from rotator cuff repair. Advances in knowledge Bursal enhancement and thickening does not reliably correlate with symptoms or presence of rotator cuff tear. PMID:23091289

    The Homerus swallowtail, Papilio (Pterourus) homerus Fabricius, is listed as an endangered species and is endemic to the Caribbean island of Jamaica. The largest butterfly in the Western Hemisphere, P. homerus once inhabited seven of Jamaica's 14 parishes and consisted of at least three populations; however, now only two stronghold populations remain, a western population in the rugged Cockpit Country and an eastern population in the Blue and John Crow Mountains. Despite numerous studies of its life history, much about the population biology, including estimates of total numbers of individuals in each population, remains unknown. In addition, a breeding program is needed to establish an experimental population, which could be used to augment wild populations and ensure the continued survival of the species. Here, we present a review of the biology of P. homerus and recommendations for a conservation plan.

    Full Text Available Defensive behavior associated with secretions from the prosternal paired glands of the larvae of Heliconius erato phyllis Fabricius (Lepidoptera, Nymphalidae. Our work presents for the first time, the defensive behavior associated with the release of the product of the prosternal paired glands of the larva of Heliconius erato phyllis Fabricius, 1775 (Lepidoptera, Nymphalidae, Heliconiinae. The prosternal glands were first described for larvae of H. erato phyllis. They are formed by two types of glandular structures: the impair gland and the paired glands. The prosternal glands are located within the conical integumentary sac, which in turn is situated on the individual's prosternum. The main goal of this study is to analyze the existence of any secretion from the prosternal paired glands, and check the action mode of this secretion. The methodology used for chemical analysis of the glands included the aeration and, analysis in gas chromatography and gas chromatography-mass spectrometry. The results show that the prosternal glands do not produce volatiles. Bioassays were conducted with simulated and natural attacks and revealed that the prosternal paired glands produce secretions of defense together with silk produced by labials glands as a defense strategy, described for the first time, against ants. The strategy consists in wrapping the ant with silk threads, the entire wrapped object moved to the end of the body, with the aid of the legs and prolegs, and possibly fixed in a nearby place. Evidence for the existence of a conical integumentary sac in larvae of other species and families of Lepidoptera allows us to propose the possibility of occurrence of prosternal paired glands with defensive function in these other groups as well.

    Full Text Available During the Ottoman period, cities were administrative units representing the existence of central authority and hegemony. It collected several activities and services within the domain and constituted a whole with its sub units in terms of administrative and civil duties. The development of city was dependent on the development of common life areas, which are neighborhoods. It was possible to see this structure, which is the basis of Ottoman urbanism, in Bursa, Edirne, Istanbul and some other Anatolian cities. Particularly Bursa has rapidly grown within the two centuries following the conquest and displayed a fine example of urbanization as a historical and cultural center. The idle fields in the city were allocated to Turkish tribes, new neighborhoods were established and the nearby villages were transformed into neighborhoods, increasing the total number of neighborhoods in the city. Beside this physical development, the newly established neighborhoods were given Turkish names as the old neighborhoods’ names were also made Turkish. Within this context, it was important to create a neighborhood in the localization of Bursa and the names given to those neighborhoods were also important. Because the names of places are the living documents for the habitation (settlement history of a nation. Studies to be conducted on neighborhood names are the research subjects of several social sciences such as sociology and anthropology and also the linguistics. Evaluation of the names of places phonetically and morphologically will contribute to the development of toponomy, which is an important branch of linguistics. This study has reviewed the neighborhood names in Hulâsatü’l-Vefeyât, a work of Gazzizâde Abdüllatif Effendi, which is considered as an urban monograph among the monographs on Bursa. The review was conducted on the copy of the author which was registered in Süleymaniye Library Assad Effendi, numbers 2257. First, information is provided

    To evaluate the frequency of inadvertent penetration of the digital flexor tendon sheath (DFTS) and/or distal interphalangeal joint (DIPJ) when using a direct endoscopic approach to the navicular bursa, and to evaluate an alternate direct approach to the navicular bursa. Cadaveric study. Equine cadaver limbs (n = 40 for direct; n = 12 for alternate approach). Four surgeons performed the direct endoscopic approach to the navicular bursa on 10 limbs each. Frequencies of inadvertent synovial penetration and iatrogenic damage were compared between surgeons. Use of an alternate direct approach, adopting a straight parasagittal trajectory, was evaluated by 2 surgeons. Inadvertent synovial penetration occurred in 45% of limbs (DFTS 37.5%; DIPJ 17.5%; and both structures 10%). Successful bursa entry was achieved on the first attempt in 45% of limbs. Significant variation in frequency of inadvertent synovial penetration was observed between surgeons (range 10-80%). Inadvertent synovial penetration did not occur when using the alternate direct technique. Iatrogenic damage to navicular bone fibrocartilage and/or deep digital flexor tendon occurred in 55% of limbs using the direct endoscopic approach and in 0% of limbs using the alternate direct approach. Because of the considerable risk of inadvertent penetration of the DFTS and/or the DIPJ when making a direct endoscopic approach to the navicular bursa, it is advisable to investigate for inadvertent penetration when treating navicular bursa sepsis using a direct approach. The alternate direct technique may reduce the risk of inadvertent penetration; however, the view within the bursa may be restricted. © 2016 The Authors.

    In recent years, modeling in long memory properties or fractionally integrated processes in stochastic volatility has been applied in the financial time series. A time series with structural breaks can generate a strong persistence in the autocorrelation function, which is an observed behaviour of a long memory process. This paper considers the structural break of data in order to determine true long memory time series data. Unlike usual short memory models for log volatility, the fractional Ornstein-Uhlenbeck process is neither a Markovian process nor can it be easily transformed into a Markovian process. This makes the likelihood evaluation and parameter estimation for the long memory stochastic volatility (LMSV) model challenging tasks. The drift and volatility parameters of the fractional Ornstein-Unlenbeck model are estimated separately using the least square estimator (lse) and quadratic generalized variations (qgv) method respectively. Finally, the empirical distribution of unobserved volatility is estimated using the particle filtering with sequential important sampling-resampling (SIR) method. The mean square error (MSE) between the estimated and empirical volatility indicates that the performance of the model towards the index prices of FTSE Bursa Malaysia KLCI is fairly well.

    Full Text Available Enclosed shopping malls are one of the most preferred spaces in our daily lives. In these places, visual and climatic comfort conditions of the users are generally provided by artificial systems instead of natural ones. In order to provide user satisfaction which is one of the most important requirements for the viability of these centers, the usage of these artificial systems causes higher energy consumption. In this study, it is argued that spatial organization scheme of shopping malls affects the subjective thoughts of the users’ interior comfort conditions (thermal, interior space air quality, natural ventilation, day lighting, audial comfort. In this context, 7 large shopping malls in Bursa were selected as case studies and the questionnaire aiming to evaluate the users’ satisfaction about comfort conditions in these shopping malls was carried out. The aim of the study is to identify the effects of architectural design principles and spatial organization schemes on the users’ evaluation of comfort conditions. The results of the questionnaire are classified under subtitles such as interior heat, thermal comfort, interior air quality and natural ventilation, day lighting, audial comfort .In this context, at the end of the study, the relation between the users’ subjective evaluation of comfort conditions and architectural design principles are comparatively discussed and some suggestions for the design of new shopping malls are provided

    Eurasian harvestmen have been introduced to, and have established themselves in North America. Species known to have been introduced include Trogulus tricarinatus (L.) 1767, Paroligolophus agrestis (Meade) 1855, Rilaena triangularis (Herbst) 1799, Oligolophus tridens (C. L. Koch) 1836, and Nemastoma bimaculatum (Fabricius) 1775, for the last of which new Canadian records (Ontario) are given below. It is not entirely determined if the species Phalangium opilio (L.) 1758, Opilio parietinus (DeGeer) 1778 and Mitopus morio (Fabricius) 1779 are introduced to North America, or are naturally of Holarctic distribution. The former seems the more likely hypothesis for the first two, but M. morio in North America may be native or may not be that species. Detailed descriptions and illustrations of all these species may be found in Martens (1978).

    Trace element dry deposition fluxes were measured using a smooth, greased, knife-edge surrogate surface (KSS) holding greased Mylar strips in Bursa, Turkey. Sampling program was conducted between October 2002 and June 2003 and 46 dry deposition samples were collected. The average fluxes of crustal metals (Mg, Ca, and Fe) were one to four orders of magnitude higher than the fluxes of anthropogenic metals. Trace element fluxes ranged from 3 (Cd) to 24,230 (Ca) microg m(-2) d(-1). The average trace element dry deposition fluxes measured in this study were similar to those measured in other urban areas. In addition, ambient air samples were also collected simultaneously with flux samples and concentrations of trace elements, collected with a TSP sampler, were between 0.7 and 4900 ng m(-3) for Cd and Ca, respectively. The overall trace element dry deposition velocities, calculated by dividing the fluxes to the particle phase concentrations ranged from 2.3+/-1.7 cm s(-1) (Pb) to 11.1+/-6.4 cm s(-1) (Ni). These values are in good agreement with the values calculated using similar techniques. The anthropogenic and crustal contributions were estimated by employing enrichment factors (EFs) calculated relative to the average crustal composition. Low EFs for dry deposition samples were calculated. This is probably due to contamination of local dust and its important contribution to the collected samples.

    In the present study, the in vivo micronucleus (MN) test in fish erythrocytes was used to evaluate the genotoxic potentials of water samples collected from four different sites along the Nilufer Stream which empties into the Marmara Sea on the north-west of Turkey. Nilufer Stream receives discharges of industrial and domestic wastes resulting from industrialization and urbanization activities in Bursa city. Nile tilapias (Oreochromis niloticus) were exposed to collected water samples under laboratory conditions for 3 and 6 days. Micronuclei analyses were carried out in peripheral blood erythrocytes. In addition to micronuclei, other nuclear abnormalities (NAs) such as bi-nucleated cells and binuclei with nucleoplasmic bridge and cells with blebbed, notched and lobbed nuclei, were assessed in the erythrocytes. Chemical analyses were also carried out in the water samples to assess the presence of major pollutants. MN and NA frequencies were significantly elevated in fishes exposed to water from polluted areas compared to those exposed to clean water sample. The results of this study indicate that Nilufer Stream is contaminated with potential genotoxic chemicals and the genotoxicity is possibly related with the industrial, agricultural and domestic activities.

    Full Text Available Adults and larvae of Leptotrachelus dorsalis (Fabricius, the Sugarcane Savior Beetle, live in association with grasses, the larvae in the appressed leaf axils. Both adult and larval L. dorsalis eat larvae of the Sugarcane Borer, Diatraea saccharalis (Fabricius, and perhaps other insects living in the confines of the leaf sheaths of that and other grass-like species. The geographic range of L. dorsalis extends from Kansas in the west to the Atlantic seaboard, north as far as Ontario, Canada and south to Cuba; it is an eastern species of North America and the Caribbean. Larval character attributes that are shared with a related ctenodactyline, Askalaphium depressum (Bates, provide a preliminary basis for characterization of the immatures of tribe Ctenodactylini.

    The city of Bursa, which is located near to the North Anatolian Fault Zone has a very active tectonic regime. The city has a local site effect problem, which is the subject of many studies for this region due to take place in the middle of the basin of the city center. However, in line with the law of new urban transformation, Turkey has started renovation of damaged old buildings and sub-urban buildings. The first example of study has been conducted in Bursa City Center in the district of Yıldırım and that has covered a big area. We used Turkish/Eurocode-8 Standard and Microzonation Criteria for all of this study. The study area covered 7 sub-district areas in particular the southern part of the conservancy district of the plains and northern part of the Uludag slope. We carried out geophysical (microtremors, seismic refraction method, surface wave analysis methods (MASW-MAM) and vertical electrical sounding) and geotechnical (boring up to 20 m and laboratory testing) studies at 75 sites to estimate elastical parameters, soil group, soil classification, and geological cross-sections. The study area was divided into two sub-areas as slope rubble (in the southern part) and alluvial deposits by using borehole data. Standard penetration tests were applied for each 1.5 m to all the boreholes and to estimate mechanical and index properties of soils, several laboratory test were applied to soil/rock specimens. Several soil problems such as soil bearing capacity, soil liquefaction potential, soil settlement analysis, soil amplification, soil expansion analysis were solved by using the results of geophysical, geotechnical and laboratory data. For the study area, deterministic and probabilistic earthquake hazard analysis was performed and ground motion level (magnitude and accelaration of design earthquake) was estimated as Mw:7.4 and a: 0.41 g for exceedence rate of 30% in 50 years. These values guided the solution of soil dynamic analysis. Vs30 map of soils for the

    Determination of the postmortem interval (PMI) is crucial for investigating homicide. However, there are currently only limited methods available. Especially, once the PMI exceeds the duration of pre-adult development of the flies with the adult emergence, its determination is very approximate. Herein, we report the regular changes in hydrocarbon composition during the weathering process of the puparia in the field in Chrysomya megacephala (Fabricius) (Diptera: Calliphoridae), one of the common species of necrophagous flies. Correlation analysis showed that the relative abundance of nearly all of the branched alkanes and alkenes decreased significantly with the weathering time. Especially, for 9 of the peaks, over 88% of the variance in their abundance was explained by weathering time. Further analysis indicated that the regular changes caused mainly by the different weathering rates of various hydrocarbons. Additionally, the weathering rates were found to depend on the chemical structure and molecular weight of the hydrocarbons. These results indicate strongly that hydrocarbon analysis is a powerful tool for determining the weathering time of the necrophagous fly puparia, and is expected to markedly improve the determination of the late PMI.

    The control of anaemia in women of childbearing age is essential to prevent low birth weight and perinatal and maternal mortality. The aim of this study was to determine the anaemia prevalence and risk factors in women of reproductive age group in Nilufer Public Health Training and Research Area, Bursa, Turkey. In this cross-sectional study, 530 women were selected using stratified random sampling among 6,506 women in 15-49 age group and 488 women (92.1%) participated in the study. Pregnant women or women who were not sure of their pregnancy were not included in the study. The data collected were analysed by multivariate logistic regression analysis to determine the risk factors related to anaemia. The prevalence of anaemia was 32.8 per cent (haemoglobin level < 12 g/dl). Usage of more than 2 sanitary pads in a day during menstruation (OR=3.67, 95% CI 2.30-5.88; P=0.000) and duration of menstrual bleeding more than 5 days (OR=3.01, 95% CI 1.94-4.66; P=0.000) were found to be risk factors for anaemia. Approximately 1 of 3 women in the study area was diagnosed to be anaemic. These data indicated the necessity of a public health programme for prevention and early diagnosis of anaemia. Starting from adolescence, all non pregnant women should be screened for anaemia every 5-10 yr throughout their childbearing years during routine health examinations. The follow up service provided by midwives at the primary health care can be used as a suitable tool for anaemia prevention.

    Full Text Available Chawkbazar in Dhaka and Covered Bazaar in Bursa are two unique examples showing the contradiction among the traditional and the contemporary life-styles and their reflections on space uses and architecture. The first example in Dhaka is one of the prime icons of Mughal architecture in Bangladesh, whereas the second one in Bursa is the first example of the typical nucleus of traditional Ottoman city. Based on these two case studies in Dhaka (Bangladesh and Bursa (Turkey, this paper attempts to illustrate how the emerging cultures and spaces are continuously being either negotiated or contested with their adjacent historic sites (Shakur, 2005. This comparative research between two similar historical sites (Mughal and Ottoman but miles apart geographically is intended to understand the commonalities in its economic, social, cultural aspects through its transformation from the historic to the contemporary period. It highlights the socio-economic and cultural transformation and its implications for future conservation and development.

    Full Text Available Osteochondroma (OC is the most common benign bone tumor and may occur on any bone in which endochondral ossification develops. Although scapular OC accounts for less than 5% of the cases of solitary OC, OC is the most common lesion among the tumors and tumor-like lesions of the scapula. OC that develops near the medial scapular border easily causes friction with the ribcage; hence, almost half the number of cases of OC associated with marked bursa formation develops in the ventral scapula. We report a case of a 27-year-old female with a painful OC of the ventral scapular surface associated with large bursa formation and pseudowinging of the scapula. After l2 years of follow-up with magnetic resonance imaging, we confirm that the accompanied bursa left at surgery disappears.

    Pigmented villonodular synovitis (PVNS) is a rare, benign, proliferating disease affecting the synovium of joints, bursae, and tendon sheaths. Involvement of bursa (PVNB, pigmented villonodular bursitis) is the least common, and only few cases of exclusively extra-articular PVNB of the pes anserinus bursa have been reported so far. We report a case of extra-articular pes anserine PVNB along with a review of the literature. The lesion presented as a painful soft tissue mass in the medial part of the proximal leg. A magnetic resonance imaging showed areas of low to intermediate signals in all sequences and the lesion enhanced heterogeneously with contrast. Diagnosis was confirmed by an incisional biopsy, and an intralesional resection was performed. The postoperative course was uneventful, and the patient is free of disease with no functional deficit at 2 years followup. As with other rare lesions, clinical and radiographic findings in addition to histological examination are essential for correct diagnosis. PMID:21687595

    To determine clinical outcome following intrathecal injection of the podotrochlear (navicular) bursa for signs of foot pain in horses evaluated via magnetic resonance imaging (MRI) and evaluate efficacy of corticosteroids administered with or without hyaluronate. Retrospective case series. 23 horses. Data collected included signalment, history, intended use, duration and severity of lameness, results of diagnostic anesthesia, radiographic abnormalities, MRI abnormalities, and outcomes for return to use. MRI was conducted on 23 horses with lameness localized to the foot. Thirteen horses had bilateral forelimb lameness, and 10 had unilateral forelimb lameness. Mean duration of lameness was 10.5 months. Seventeen of 23 (74%) horses had excellent outcomes and returned to intended use within 2 to 4 weeks after navicular bursa injection. Hyaluronate treatment was not associated with outcome; however, horses receiving bursa should be highly effective in alleviating lameness.

    Despite being one of the dominant groups in freshwater ecosystems, morphological and ontogenetic studies on aquatic Hemiptera have received little attention in the Oriental region. We present the ontogenetic trajectory and allometry of the widespread Oriental belostomatid species, Diplonychus rusticus (Fabricius) for the first time. We have measured nine different morphological variables throughout the growth of the bug using both field captured and laboratory reared specimens. Our results suggest that the developmental instars can be distinguished by the size variables, as seen in the Principal Component Analysis. On the basis of a CHAID (Chi-squared Automatic Interaction Detection) based regression tree, we also show that the characters - total length without head and maximum width - prove to be adequate for effective instar identification. The multivariate allometric growth pattern shows that different body parts exhibit different types of allometry. This is apparent in the allometry exhibited by forelegs and mid and hind legs, which show allometry of opposite polarities. This may be due to the different functions attributed to these body parts. Our results show that the growth pattern in D. rusticus is comparable with the New World genus Belostoma, suggesting a conserved growth pattern in the family Belostomatidae.

    It was hypothesized that preserving a layer of gliding tissue, the parietal layer of the ulnar bursa, between the contents of the carpal tunnel and the soft tissues incised during carpal tunnel surgery might reduce scar pain and improve grip strength and function following open carpal tunnel decompression. Patients consented to randomization to treatment with either preservation of the parietal layer of the ulnar bursa beneath the flexor retinaculum at the time of open carpal tunnel decompression (fifty-seven patients) or division of this gliding layer as part of a standard open carpal tunnel decompression (sixty-one patients). Grip strength was measured, scar pain was rated, and the validated Patient Evaluation Measure questionnaire was used to assess symptoms and disability preoperatively and at eight to nine weeks following the surgery in seventy-seven women and thirty-four men; the remaining seven patients were lost to follow-up. There was no difference between the groups with respect to age, sex, hand dominance, or side of surgery. Grip strength, scar pain, and the Patient Evaluation Measure score were not significantly different between the two groups, although there was a trend toward a poorer subjective outcome as demonstrated by the questionnaire in the group in which the ulnar bursa within the carpal tunnel had been preserved. Preserving the ulnar bursa within the carpal tunnel did, however, result in a lower prevalence of suspected wound infection or inflammation (p = 0.04). In this group of patients, preservation of the ulnar bursa around the median nerve during open carpal tunnel release produced no significant difference in grip strength or self-rated symptoms. We recommend incision of the ulnar bursa during open carpal tunnel decompression to allow complete visualization of the median nerve and carpal tunnel contents.

    This paper discusses the occurrence and development of the excavation-induced deep-seated landslide, which took place near Dundar village, located west of Orhaneli town in northwestern Turkey. The event occurred in the Bursa-Orhaneli lignite field. Due to undermining of a gently inclined slope (10{sup o}) to extract a coal seam, primary tension cracks, which were precursors of the movement, were first observed in the northern head area in mid- to late October 2003. This movement happened simultaneously with precipitation that was significantly above long-term average measured at a nearby climatology station (Keles). Daily climatic and synoptic meteorological data have proved that heavy showers in late April may have triggered the last slump by producing rain showers of 19.3 mm and 19.9 mm daily total on 27 and 28 April 2004, respectively. Field observations carried out along the main head scarp have shown that the slope failure was facilitated by a pre-existing normal fault with an east-west direction and 80{sup o} dip. Grain-size analysis showed that the failure occurred on clayey silt, which forms 55% of the slip surface material. The landslide occurred over an area of 600 m x 650 m with a total volume of 8775 000 m{sup 3}. Approximately 28 hectares of farm land were entirely destroyed and the excavated coal seam was buried. The mining operation was moved to 100 m north of the landslide area near Gumuspinar village. From morphological evidence, it is concluded that excavation activities caused the failure to extend in more than one direction as an enlarging sliding mechanism; this produced a high landslide risk for Gumuspinar village, where the most significant normal fault with a 75 m vertical displacement in a coal-bearing sequence is found in the lignite field.

    Behavioral and electrophysiological tests were performed to evaluate the responses of workers of the ant Solenopsis geminata (Fabricius) from different size categories to Dufour gland extracts. Morphometric measures based in head widths across eyes were used to determine worker sizes. Trail following response of different worker sizes to Dufour gland extract from workers of different sizes was assessed. For each worker size category olfactory responses to Dufour gland extracts were determined using electroantennography (EAG). Gas chromatography and mass spectrometry (GC-MS) were used to determine the chromatographic profile of Dufour gland secretion for each worker size. Morphometric measures permitted to classify the workers of S. geminata as large, medium and small workers. Medium S. geminata workers displayed a significantly higher behavioral response to Dufour gland extracts produced by medium size workers. Similarly, medium workers showed a significantly higher EAG response to Dufour gland extracts produced by medium sized workers. Chromatographic profile of Dufour gland secretions produced by workers showed that each size category exhibited a characteristic profile of the three main components considered as potential trail pheromone constituents. This work showed that medium workers of S. geminata exhibited a high trail-following behavior as well as a high antennal response to Dufour gland secretion. This and their relative abundance in field foraging areas, suggest that medium-sized workers are specialized in foraging activities. (author)

    The purpose of the study was to determine if the thickness of the subacromial-subdeltoid (SASD) bursa during dynamic ultrasound and on static views differs between patients with shoulder impingement syndrome and healthy volunteers. Twenty-two patients with a clinical diagnosis of shoulder impingement syndrome and 23 healthy volunteers were recruited. A subset of patients showing an immediate symptom response following intrabursal injection was identified as "injection responders". Ultrasound of the shoulder was performed on all participants using three standard static views and two dynamic views (before and after arm abduction). The thickness of both the intrabursal fluid and the superficial peribursal fat was measured on all views. The bursal thickness measurements in the two groups were compared using a t test for significance. The mean increase in SASD bursal fluid thickness following arm abduction was not statistically different among all patients (0.39 ± 0.41 mm) and controls (0.35 ± 0.32 mm), p = 0.72. The same was true comparing injection responders (0.46 ± 0.49 mm) with controls, p = 0.41. On static views, greater bursal fluid thickness was found in patients (1.01 ± 0.48 mm) compared with controls (0.67 ± 0.32 mm) when using the short axis view of the supraspinatus, p = 0.006. No statistically significant difference was found between injection responders and controls when measuring peribursal fat thickness on any view. Gathering of the SASD bursa demonstrated during dynamic ultrasound does not necessarily indicate painful impingement of the bursa as it is found to a similar degree in patients with a clinical diagnosis of impingement and healthy volunteers.

    Full Text Available Of major importance in realizing the potential of edible insects as a core element in improving food security, sustainable food production, and biodiversity conservation, are developments in sustainable exploitation of wild edible insect populations and in (semi-cultivating and farming edible insects. Such developments can draw on both western science and indigenous knowledge. Oecophylla smaragdina Fabricius Hymenoptera: Formicidae, of which particularly the queen brood is commonly consumed in Thailand and the Lao PDR, is believed to have the potential to act as flagship/umbrella species in forest conservation and management, to be incorporated simultaneously as biological control agent and direct source of human food in agroforestry practices, and to be (semi-cultivated. We provide a detailed account of indigenous knowledge of O. smaragdina and ant brood collection practices from the Vientiane Plain, Lao PDR, through focus group discussions and participant observations, and then reflect on sustainability and conservation issues, and on semi-cultivating constraints and possibilities embedded in indigenous knowledge and ant brood collection practices.

    Western Anatolia (Turkey) experienced widespread Cenozoic magmatism after the collision between the Sakarya and Anatolide-Tauride continental blocks in the pre-middle Eocene. The widespread magmatic activity in NW Anatolia postdates this continental collisional event in the region. The following magmatic episode during the Oligocene and Early Miocene is known to have produced the widespread granitic plutons. Many skarn mineralization associated with plutons formed in the region (such as Hayriye and Arapdede Mineralizations). The Paleozoic aged Devlez Metabasite is the oldest unit of the study area. This unit includes amphibolite, glaucophane-lawsonite schist, muscovite schists. The unit has widely spread in area. This units are overlain unconformably by the Geyiktepe Marbles. Paleocene aged Domaniç granitoidic intrusives cut other rock series and located as a batholite. Magmatic units present porphyric and holocrystalline textures. Granitoidic intrusions are represented by tonalite, tonalite porphyr, granodiorite, granodiorite porphyr, granite, diorite, diorite porphyries. The Domaniç granitoid intruded in to the metamorphides during Paleocene and caused formations of skarn zones and related Cu-Pb-Zn mineralizations along the contacts. Mineralizations are known in the locations named as Arapdede and Hayriye. The mineralizations occur along the metamorphites - plutonics contact, in the pockets and fractures extending towards marble. The thickness of the mineralized bodies can reach up to 1 -2 m. Primary minerals are galenite, magnetite, pyrite, chalcopyrite and sphalerite at Hayriye mineralizations and sphalerite, galenite, chalcopyrite and pyrite minerals at the Arapdede mineralizations.

    Traumatic lesions of the olecranon bursa (OB) and prepatellar bursa (PB) are injuries commonly seen in orthopaedic trauma units. These injuries are associated with a high rate of complications. At present, only little is known about the incidence, complication rate, and treatment approaches in patients with acute open bursae. A total of 552 patients who had been treated for acute traumatic lesions of either the olecranon bursa or the prepatellar bursa, or both at our department were retrospective identified in the years between 2009 and 2014. An analysis of the medical history of these patients was carried out to investigate the incidence of bursa injuries, circumstances, concomitant injuries, complication rate, and treatment approaches. In addition, a systematic literature search on PubMed was conducted. The incidence of traumatic lesions of the OB or PB in trauma patients was 0.2% (198/100,000; 62% OB, 38% PB). Bursectomy was performed in 83.7%. Concomitant injuries were present in 41% of the cases, with no significant influence on the complication rate (P = 0.367). The overall complication rate was 19.7%. Revision surgery was necessary in 4.5% of the patients. No significant differences between OB and PB injuries were noted with regard to the complication rate (P = 0.221). There were also no significant differences in the complication rate between patients who received bursectomy and those with conservative treatment (P = 0.364). Regression analyses showed that prophylactic antibiotic administration significantly reduced the risk of infection (P = 0.04). Traumatic lesions of the OB and PB are associated with a high risk of complications. Prophylactic antibiotic therapy can potentially reduce the risk of infection and the need for revision surgery.

    Patients with a shoulder disorder often complain of pain on the anterior or lateral aspect of the shoulder. Such pain has been thought to originate from the suprascapular nerve. However, taking into consideration the distinctive course of the axillary nerve, the axillary nerve is likely to supply branches to the structure around the shoulder joint. This study was conducted to clarify the division, course, and distribution of the branches which originate from the axillary nerve and innervate structures around the shoulder joint. The division, course, and distribution of the branches which originate from the axillary nerve and innervate structures around the shoulder joint were examined macroscopically by dissecting 20 shoulders of 10 adult Japanese cadavers. The thin branches from the anterior branch of the axillary nerve were distributed to the subacromial bursa and the area around the long head of the biceps tendon. The branches from the main trunk of the axillary nerve or the branch to the teres minor muscle were distributed to the infero-posterior part of the shoulder joint. The pain on the anterior or lateral aspect of the shoulder, which has been thought to originate from the suprascapular nerve, might be related to the thin branches which originate from the axillary nerve and innervate the subacromial bursa and the area around the long head of the biceps tendon. These results would be useful to consider the cause of the shoulder pain or to prevent the residual pain after the biceps tenodesis.

    Trochanteric bursa injections of corticosteroids and local anesthetics have been shown to provide pain relief for the treatment of greater trochanteric pain syndrome (GTPS). However, symptom recurrence and incomplete symptom relief are common. The reason for the variation in response is unclear but may be related to disease-, treatment-, or patient-related factors. To determine whether there are factors related to patient, treatment, or disease that can predict either the magnitude or duration of response to ultrasound-guided trochanteric bursa injections for GTPS. Retrospective evaluation. A university hospital outpatient center. Potential study participants were patients who underwent ultrasound-guided trochanteric bursa injection at an outpatient rehabilitation department. Follow-up interviews were performed in a hospital visit at 1, 3, and 6 months after injection. The Harris Hip Score and the Verbal Numeric Pain Scale were used to evaluate clinical effectiveness of pain reduction and functional improvement at baseline, 1, 3, and 6 months after treatment. Clinical data and ultrasound findings were obtained to assess the possible predictive factors for a good and durable response to ultrasound-guided trochanteric bursa injection. Patients receiving ultrasound-guided trochanteric bursa injections had a statistically significant improvement in pain and hip function at 1, 3, and 6 months after the last injections. Of the 137 patients, 110 (80.3%), 95 (64.9%), and 77 (56.2%) patients achieved successful outcomes according to their 1, 3, and 6-month follow-up evaluations, respectively. Univariate analysis showed that patients with knee osteoarthritis and lumbar facet joint or sacroiliac joint pain experienced less therapeutic effect than those without the conditions at 6 months post-injection. Logistic regression analysis showed that the significant outcome predictors at the 6-month follow-up were facet joint or S-I joint pain (odds ratio = 0.304, P = .014) and knee

    To evaluate the involvement of the bursa located next to the head of the 5th metatarsal bone in patients with psoriatic arthritis (PsA) in comparison with the other seronegative spondyloarthritis (SpA). All patients with PsA seen during a period of 24 months were enrolled. The control group included healthy subjects and patients with the other SpA. All subjects underwent clinical and ultrasound (US) examination of the lateral surface of the 5th metatarsal. 150 PsA patients (88 M; 62 F), 172 SpA (107 M; 65 F), and 95 healthy controls (58 M; 37 F) were evaluated. Based on clinical and US evaluation, bursitis was diagnosed in 17/150 (11.3%) PsA patients but in none of the SpA (P bursa of the 5th metatarsophalangeal joint appears to be involved in PsA more frequently than by chance. If confirmed by other studies, this finding could be considered as a distinctive clinical sign of PsA, useful for differential diagnosis with the other SpA. In asymptomatic patients, US proved to be more sensitive in the detection of bursitis.

    Records of ambient seismic noise (ASN) field are widely used to obtain seismic velocity structures at both engineering and global scales. Two well-known methods commonly employed to obtain shear-wave velocity profiles, in engineering seismology, are the frequency-wavenumber (FK) transform and spatial auto-correlation (SPAC) methods that are based on the analysis of ASN field recorded by 2D sensor arrays. At global scale on the other hand, seismic velocity structure is determined by the Green's function retrieved from cross-correlation of the ASN recorded between two seismic stations. In the last decade, this approach has become complementary or almost alternative to the conventional methods of surface wave tomography used to investigate the velocity structure of the crust and upper mantle. Similarly, in recent years, the Green's functions estimated from ASN have also been used to investigate the shear-wave velocity structure of basins and their site amplification properties. This work presents the Rayleigh wave Green's functions retrieved from the vertical-component ASN data recorded in the Bursa and Adana basins of Turkey. This constitutes the first stage of our research whose objective is to investigate whether velocity structures of these basins can reliably be obtained from tomographic inversion. The continuous data used in our study were recorded between 2010 and 2013 by the national seismic networks operated by Kandilli Observatory and Earthquake Research Institute (KOERI) of Bosphorus University and Earthquake Research Department (ERD) of Disaster and Emergency Management Presidency of Turkey. For both basins, distances between station pairs are in the range of 30-200 km. In this distance range, the Green's functions reveal Rayleigh waves with the periods of 6 to 30 s. Group velocity dispersion analysis carried out by the multiple filtering technique show that the group velocities are estimated to be in the range of 2.5-4.0 km/s. Observed variation of group

    Full Text Available The effects of water and feed fasting for 24, 48 and 72 hours post-hatching on blood parameters (mean corpuscular volume, MCV; red blood-cell, RBC; hematocrit, HCT; hemoglobin, HGB; plasma glucose, CGP; plasma total protein, PP, and differential leukocytes count, and on body, liver, spleen, bursa, and yolk sac weights were analyzed. Erythrogram data were obtained with a blood cell counter. Total plasma protein and plasma glucose were determined by using the Bradford method (1976 and a glucose PAP liquiform kit (Labtest, cat. n. 84, respectively. Specific leukocyte counts were carried out on blood smears stained with Rosenfeld solution. According to the obtained data, water and feed post-hatching fasting reduced MCV values, which also were lower in males than that in females. Fasting for 48 hours promoted an increase in PP, while fasting for 72 hours reduced HCT. Chicks submitted to fasting presented lower body weights as compared to fed chicks, but their liver weight did not increase between 48 and 72 hours of age. Fasting decreased spleen weight, but bursa and yolk sac weight were not affected. Data showed that female and male chicks react in a similar way to post-hatching fasting, which affects body weight, liver and spleen weight, and HCT and PP values. Moreover, 72 hours of fasting affected more intensely HCT and MCV values.

    Full Text Available The primary function of artisans’ and commercial guilds was toperform and maintain daily activities of economic life in harmony andsocial consolidation with minimal conflict. Thus, the state would get ridof the heavy burden of bureaucratic procedures on the one hand, and yetwould also have the guilds yield to a standard of production as well aseliminate unfair competition through their autonomous internal workingson the other. Through such an auto-control mechanism the guilds wouldsolve their own problems with minimum resort to administrative andjudicial institutions. This article sheds light on the origins of Ottomanguild system, workings of trade guilds of Bursa and the supervisoryfunctions of their managers as well as on the various roles and activitiesplayed by the guilds in imperial public life. It also examines the conflictsof interest, unruly acts and forms of resolution taking place within andacross the guilds, with or without having recourse to judicial and otherimperial authorities. The study is based on a set of original historical documents surveyed from the Shari’a Court records of Bursa in the 16thand 17th centuries.

    Insect specimens collected from decomposing bodies enable forensic entomologists to estimate the minimum post-mortem interval (PMI). Drugs and toxins within a corpse may affect the development rate of insects that feed on them and it is vital to quantify these effects to accurately calculate minimum PMI. This study investigated the effects of morphine on growth rates of the native Australian blowfly, Calliphora stygia (Fabricius) (Diptera: Calliphoridae). Several morphine concentrations were incorporated into pet mince to simulate post-mortem concentrations in morphine, codeine and/or heroin-dosed corpses. There were four treatments for feeding larvae; T 1: control (no morphine); T 2: 2 microg/g morphine; T 3: 10 microg/g morphine; and T 4: 20 microg/g morphine. Ten replicates of 50 larvae were grown at 22 degrees C for each treatment and their development was compared at four comparison intervals; CI 1: 4-day-old larvae; CI 2: 7-day-old larvae; CI 3: pupae; and CI 4: adults. Length and width were measured for larvae and pupae, and costae and tibiae were measured for adults. Additionally, day of pupariation, day of adult eclosion, and survivorship were calculated for each replicate. The continued presence of morphine in meat was qualitatively verified using high-performance liquid chromatography with acidic potassium permanganate chemiluminescence detection. Growth rates of C. stygia fed on morphine-spiked mince did not differ significantly from those fed on control mince for any comparison interval or parameter measured. This suggests that C. stygia is a reliable model to use to accurately age a corpse containing morphine at any of the concentrations investigated.

    The Artocarpus fruit fly, Bactrocera umbrosa (Fabricius) (Diptera: Tephritidae), is an oligophagous fruit pest infesting Moraceae fruits, including jackfruit (Artocarpus heterophyllus Lamarck), a fruit commodity of high value in Malaysia. The scarcity of fundamental biological, physiological and ecological information on this pest, particularly in relation to behavioural response to phytochemical lures, which are instrumental to the success of many area-wide fruit fly control and management programmes, underpins the need for studies on this much-underrated pest. The positive response of B. umbrosa males to methyl eugenol (ME), a highly potent phytochemical lure, which attracts mainly males of many Bactrocera species, was shown to increase with increasing age. As early as 7 days after emergence (DAE), ca. 22% of males had responded to ME and over 50% by 10 DAE, despite no occurrence of matings (i.e. the males were still sexually immature). Male attraction to ME peaked from 10 to 27 DAE, which corresponded with the flies' attainment of sexual maturity. In wind-tunnel assays during the dusk courtship period, ME-fed males exhibited earlier calling activity and attracted a significantly higher percentage of virgin females compared with ME-deprived males. ME-fed males enjoyed a higher mating success than ME-deprived males at 1-day post ME feeding in semi-field assays. ME consumption also promotes aggregation behaviour in B. umbrosa males, as demonstrated in wind-tunnel and semi-field assays. We suggest that ME plays a prominent role in promoting sexual communication and enhancing mating performance of the Artocarpus fruit fly, a finding that is congruent with previous reports on the consequences of ME acquisition by other economically important Bactrocera species.

    The purpose of the study was to demonstrate the prevalence of communication between the hip joint and the obturator externus bursa on hip MR arthrography. Following institutional review board approval, 200 hip MR arthrograms in 196 subjects were independently reviewed by two musculoskeletal radiologists. Discrepancies were resolved by adjudication. The presence or absence of communication between the hip joint and the obturator externus bursa was recorded. Associated lesions involving the acetabular labrum and articular cartilage were recorded. The obturator externus bursa was shown to communicate with the hip joint in 11 of the 200 (5.5%) hip MR arthrograms. Of these, six were in men and five were in women. The age range was 15-63 years with a mean age of 34 years. All 11 patients had labral tears. Eight of the 11 had cartilage lesions. The obturator externus bursa can be seen to communicate with the hip joint in 5.5% of hip MR arthrograms. Associated labral and cartilage lesions are common.

    The common cutworm, Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae), is a destructive pest in Asia. Although overwintering in the field has not been reported for this species, their larvae are capable of long-term survival in fluctuating temperatures, i.e., 5°C (12h) plus 13°C (12h), if food is available. With an increase in climate change due to global warming and the widespread use of greenhouses, further understanding of their cold survival strategy is needed to predict and control their population in the future. In this study, metabolomics was performed to analyze the metabolic features of S. litura larvae exposed to two typical low temperatures: 15°C and 4°C, at which the development, locomotion and feeding activities are maintained or halted, respectively. The results showed that the strategies that regulate lipid and amino acid metabolism were similar at 15°C and 4°C. Cold exposure induced a metabolic shift of energy from carbohydrate to lipid and decreased free amino acids level. Biosynthesis likely contributed to the decrease in amino acids levels even at 4°C, a non-feeding temperature, suggesting an insufficient suppression of anabolism. This explains why food and high temperature pulses are necessary for their long-term cold survival. Glycometabolism was different between 15°C and 4°C. Carbohydrates were used rapidly at 15°C, while trehalose accumulated at 4°C. Interestingly, abundant trehalose and serine are prominent features of Spodoptera exigua larvae, an overwintering species, when compared to S. litura larvae. Exposure to 4°C also induced up-regulation of carbohydrase and protease in the guts of S. litura. Therefore, it is likely that concurrence of food supplement and fluctuating temperatures could facilitate the cold survival of S. litura larvae. We also found that exposure to 4°C could activate the mevalonate pathway in S. litura larvae, which might be related to glycometabolism at 4°C. Overall, our study describes

    Full Text Available Abstract Objective: The aim of this study was to evaluate tuberculosis control programmes of patients who applied to the Bursa Nilufer Tuberculosis Dispensary and by investigating the changes in the variables over 3 decades. Method: In this retrospective descriptive study, the records of all tuberculosis cases (1662 people treated in the last 30 years (1985-2014 at the Bursa Nilufer Tuberculosis Dispensary were examined. In the analysis, the chi-square test, the trend chi-square test and Fisher's exact test were used. Results: Males comprised 65.2% of the patients. The ages of the patients ranged from 1 to 87 years, and the mean age was 37.4 (95% CI:36.6-38.2. Among the cases, 86.7% were new and 74.1% were pulmonary tuberculosis. In the last decade, the proportion of women, the education level, the proportion of patients who had received a BCG vaccination and the proportion of active employees among women increased by a statistically significant amount, while the proportion of employees among men decreased. Clinical symptoms, such as weakness, anorexia, weight loss, and cough, decreased to a statistically significant degree. In the last decade, the mortality rate was 3.6%, a statistically significant increase compared with previous decades. Mortality was statistically significant higher among patients who were elderly, male, did not have a BCG scar or had a chronic disease. Conclusion: This study reveals the need for studies that determine the risk factors associated with tuberculosis mortality and examine the effectiveness of tuberculosis control programmes. Direct measures to address mortality risk factors can reduce the number of deaths from tuberculosis.

    Several experimental surveys were carried out in the Northeastern Atlantic, Madeira archipelago from 1991 to 2008 to explore new fisheries resources. This study examined the selectivity of bottom and floating traps and the analysis of yield-per-recruit (YPR) and biomass-per-recruit (BPR) providing helpful insight to the management of the shrimp Plesionika narval. A total of 28,262 specimens were sampled and the analysis of length at first capture returned higher values when using floating traps indicating that these traps are more selective, exerting less pressure on the resource. The YPR and BPR analysis showed that the stock is under exploited for the studied area and suggests that the use of floating traps in the commercial fisheries of P. narval is recommended, which will allow a higher maximum allowable limit of exploitation and greater yield. The results suggest that P. narval has the potential to support a viable and sustainable fishery using floating traps.

    Body melanisation in insects is polygenic, resulting from genetic polymorphism or phenotypic plasticity, with diverse implications ranging from thermal budgeting to reproductive success. In this study, we assessed the, mate choice, reproductive success, and offspring colouration of typical (T) and melanic (M) morphs of the ladybird Menochilus sexmaculatus paired at three temperatures 15°C, 25°C and 35°C. Mating success of the two morphs and the consequences for offspring fitness and offspring phenotype under these temperature regimes were evaluated. Melanic adults of both sexes achieved significantly higher mating success at 15°C and 25°C, but at 35°C no influence of adult morph on mate selection was observed. Melanic females were more fecund than typical females at all temperatures. Offspring of melanic parents developed faster than those of typicals at 15°C and 25°C, but not at 35°C. Evidence was also found of phenotypic plasticity in colour form at 15°C and 35°C. At 25°C the parents of pure (T) and (M) morphs produced offspring of the same morph. However, low temperature induced partial melanisation among the offspring of typical parents (T). Whereas at 35°C the offspring of (T) parents became paler in colour with very fine zigzag lines on elytra, i.e. they decrease the degree of melanisation. Pure melanics (M) compensated for elevated temperature stress by producing offspring that were either pure melanic but small or large with reduced melanisation. Our results on offspring phenotype variation indicate that the degree of melanism in morphs is a result of environmentally regulated expression of the parental genotype.

    Insects manifest effective immune responses that include both cellular and humoral components. Morphological and quantitative aspects of cellular and humoral cooperation during nodule formation in Chrysomya megacephala hemolymph against Saccharomyces cerevisae yeast cells were demonstrated for the first time. The analyses were performed in non-injected larvae (NIL), saline-injected larvae (SIL) and yeast-injected larvae (YIL). The hemolymph of injected groups was collected 0.5, 1, 2, 4, 12, 24, 36, or 48-h post-injection. Morphological aspects of YIL nodulation were investigated using transmission electron microscopy (TEM). Quantitative analyses consisted of total (THC) and differential hemocyte counts (DHC) in all the groups and total yeast count (TYC) in YIL, which were performed in an improved Neubauer chamber. Nodule formation was initiated at approximately 2-h post-injection. Twelve hours after the injection, TEM revealed the presence of an amorphous membrane, at the same time that circulating hemocyte number decreased significantly contrasting the increase of yeast number. Our results showed the ability of C. megacephala hemolymph to perform humoral encapsulation when hemocyte population is insufficient to eliminate the microorganisms, warranting consideration in future investigations on the relative roles played by cellular and humoral elements of innate immunity of this calliphorid.

    Rotator cuff syndrome is often treated with subacromial injection of corticosteroid and local anesthetic. It has not been established if the common injection routes of the bursa are equally accurate. We conducted a prospective clinical trial involving seventy-five shoulders in seventy-five patients who were randomly assigned to receive a subacromial injection through an anterior, lateral, or posterior route with respect to the acromion. An experienced physician performed the injections, which contained radiopaque contrast medium, corticosteroid, and local anesthetic. After the injection, a musculoskeletal radiologist, blinded to the injection route, interpreted all of the radiographs. The rate of accuracy varied with the route of injection, with a rate of 56% for the posterior route, 84% for the anterior route, and 92% for the lateral route (p = 0.006; chi-square test). The accuracy of injection through the posterior route was significantly lower than that through either the anterior or the lateral route (p bursa in females.

    Full Text Available The cashew stem girdler, Analeptes trifasciata , is a major insect pest of cashew in Nigeria causing economic damage in cashew plantations even at low density. In this study, newly emerged adults of A. trifasciata reared from field-infested cashew stems were collected from the rearing cages, sexed, and dissected to reveal the internal structures of the insects. The gut was excised and separated into the foregut, midgut, and hindgut. The dissected gut compartments were blotted dry by sandwiching in sterile Whatman No. 1 (150 mm filter paper for a minute. The inoculated gut parts showed the presence of eight fungi flora, namely, Aspergillus repens, Trichoderma spp., Fusarium verticillioides, Lasiodiplodia theobromae , yeast, Aspergillus niger, Fusarium spp., and Rhizopus stolonifer . The frequencies of occurrence of bacteria in the gut compartments of A. trifasciata were Enterobacter spp.: 83.33%; Escherichia coli and Streptococcus spp.: 55.56% each; Staphylococcus spp.: 44.44%; Klebsiella pneumonia : 50% and Salmonella shigella : 11.11%, while each of Serratia marceascea, Pseudomonas spp., and Micrococcus lutea had 5.56% occurrence. The occurrence of mycoflora and microbiota species varied in the gut compartments of A. trifasciata , indicating the role of these microorganisms in metabolic and other bioprocesses of A. trifasciata during digestion and synthesis of complex food substances from the cashew stem substrate. This study would provide basic information for enzymatic studies of A. trifasciata with a view to developing an integrated pest management (IPM protocol for managing the pest in cashew plantations.

    Full Text Available This study describes the results obtained by applying the Arnason Schwartz multistate mark-recapture model to eight years of data collected in and around a small no-fishing marine protected area (MPA; 4 km2 in the central western Mediterranean. From 1997 to 2004, a total of 4044 specimens of Palinurus elephas (Fabr., 1787 were tagged and 317 recaptured. The most parsimonious model which best explained the data variability was that of a temporally constant rate of apparent survival and movement in each of the two strata. The absence of any temporal influence in the apparent survival rate inside the no-take area suggested that spillover and mortality are constant for each period of the study. The lower apparent survival rate in surrounding zones than inside the MPA (0.26 ± 0.04 (SE vs 0.94 ± 0.03 (SE is presumed to be a function of fishing effort. A continuous movement of P. elephas across the boundary of the small MPA was also tested. This information on retention of lobsters in the MPA contributes to our understanding of the effect of introducing MPAs into a managed commercial fishery system.

    Full Text Available An artificial feeding system was used where citrated bovine blood was offerred to male and female Amblyomma cajennense. Vestiges of blood, sweat, hair and exfoliated skin were used as phago-stimulants placed on the surface of the silicone membrane. The ticks were collected, as engorged nymphs, from naturally infested equines, with the ecdysis occurring in the laboratory. Four hundred ticks were used, 50% being female, at three to four weeks post-ecdysis. Vestiges of blood on the silicone membrane were the most efficient phago-stimulant and the association of vestiges of blood and sweat residue smears yielded better results compared to the other phago-stimulants used

    The giant honeybee Apis dorsata often forms dense colony aggregations which can include up to 200 often closely related nests in the same location, setting the stage for inbred matings. Yet, like in all other Apis species, A. dorsata queens mate in mid-air on lek like drone congregation areas (DCAs) where large numbers of males gather in flight. We here report how the drone composition of A. dorsata DCAs facilitates outbreeding, taking into the account both spatial (three DCAs) and temporal (subsequent sampling days) dynamics. We compared the drones' genotypes at ten microsatellite DNA markers with those of the queen genotypes of six drone-producing colonies located close to the DCAs (Tenom, Sabah, Malaysia). None of 430 sampled drones originated from any of these nearby colonies. Moreover, we estimated that 141 unidentified colonies were contributing to the three DCAs. Most of these colonies were participating multiple times in the different locations and/or during the consecutive days of sampling. The drones sampled in the DCAs could be attributed to six subpopulations. These were all admixed in all DCA samples, increasing the effective population size an order of magnitude and preventing matings between potentially related queens and drones.

  4. Cytogenetic studies on populations of Camponotus rufipes (Fabricius, 1775 and Camponotus renggeri Emery, 1894 (Formicidae: Formicinae.

    Directory of Open Access Journals (Sweden)

    Hilton Jeferson Alves Cardoso de Aguiar

    Full Text Available Two valid ant species, Camponotus rufipes and Camponotus renggeri, have recently been the subject of a broad discussion with reference to taxa synonymization. Both species are quite common among the Neotropical myrmecofauna and share some unique traits, such as the shape of the scape and the pilosity patterns of the tibiae and scapes. A single morphological trait can help distinguish these species; however, only a combination of different approaches can enlighten our view of the complex phylogenetic relationships prevailing in the different populations of these two taxa. Therefore, focusing on the taxonomic issues concerning these two species, a cytogenetic survey including 10 populations of C. rufipes and two populations of C. renggeri was performed. In order to better understand the extent of the relationship between C. rufipes and C. renggeri, two common Neotropical Camponotus species, C. atriceps and C. cingulatus were taken as outgroups. All four species of Camponotus that were studied had 2n = 40 chromosomes (4sm+34st+2t; however, the abundance of chromosome rearrangements observed, combined with several chromosome markers, suggest that C. rufipes and C. renggeri are two good distinct species although closely related. The already reported chromosome translocation 2n = 39 (1m+4sm+32st+2t for C. rufipes has been found in different populations as in the unprecedented chromosome inversions found both in C. rufipes and in C. renggeri populations. Within the C. renggeri chromosome inversions, both the heterozygous state 2n = 40 (1m+3sm+34st+2t and the homozygous state, 2n = 40 (2m+2sm+34st+2t were identified. However, only heterozygous specimens for chromosome inversions were found among C. rufipes, with karyotype configurations distinct from those found in C. renggeri, with 2n = 40 (1m+4sm+34st+2t. None of the populations studied showed signs of mosaic individuals. With respect to rDNA clusters, the 18S rDNA seemed to be more restricted inside

    Full Text Available Spodoptera litura is a notorious leaf feeding insect pest of more than one hundred plants around the Asia-Pacific region. Host plant survey for two years from three different locations in cotton belt revealed 27 plant species as host plants of S. litura belonging to 25 genera of 14 families including cultivated crops, vegetables, weeds, fruits and ornamental plants. Major host plants on which it thrived for maximum period were Gossypium hirsutum L., Ricinus communis L., Brassica oleracea var. botrytis L., Colocasia esculenta L., Trianthema portulacastrum L. and Sesbania sesban L.. Eggs were also collected from tree plants but larvae did not complete their development. Reliance of S. litura on major plant species of cultivated crops necessitates their regular monitoring especially during March to April for their population abundance and early warning for their management on commercial crops like cotton.

    Abnormalities of the deep digital flexor tendon, navicular bone, and collateral sesamoidean ligament can be difficult to visualize using magnetic resonance imaging (MRI) if bursal fluid is absent. The use of saline podotrochlear bursography improves podotrochlear apparatus evaluation, however, the technique has disadvantages. The objective of this prospective feasibility study was to describe saline arthrography of the distal interphalangeal joint as an alternative technique for improving MRI visualization of the deep digital flexor tendon, navicular bone, collateral sesamoidean ligament, and podotrochlear bursa, and to compare this technique with saline podotrochlear bursography. Eight paired cadaver forelimbs were sampled. Saline podotrochlear bursography or saline arthrography techniques were randomly assigned to one limb, with the alternate technique performed on the contralateral limb. For precontrast and postcontrast studies using each technique, independent observers scored visualization of the dorsal aspect of the deep digital flexor tendon, palmar aspect of the navicular bone, collateral sesamoidean ligament, and podotrochlear bursa. Both contrast techniques improved visualization of structures over precontrast MR images and visualization scores for both techniques were similar. Findings from this study demonstrated that saline arthrography is feasible and comparable to saline podotrochlear bursography for producing podotrochlear bursa distension and separation of the structures of the podotrochlear apparatus on nonweight bearing limbs evaluated with low-field MRI. Clinical evaluation of saline arthrography on live animals is needed to determine if this technique is safe and effective as an alternative to saline podotrochlear bursography in horses with suspected pathology of the podotrochlear apparatus. © 2015 American College of Veterinary Radiology.

    Each arthroscopic portal to the knee has a blind area that cannot be inspected directly. In particular, visualization of the posterior compartment is difficult to access. Although arthroscopic procedures for the posterior compartment of the knee joint have been developed through posteromedial, posterolateral and posterior trans-septal portal, the popliteal bursa remains as an area that is difficult to access and manipulate. We report a surgical procedure that can examine one of the blind spots in knee arthroscopy, popliteal bursa.

    Full Text Available In this paper, two methods for assessing the degree of melanization of pupal exuviae from the butterfly Heliconius erato phyllis , Fabricius 1775 (Lepidoptera, Nymphalidae, Heliconiini are compared. In the first method, which was qualitative, the exuviae were classified by scoring the degree of melanization, whereas in the second method, which was quantitative, the exuviae were classified by optical density followed by analysis with appropriate software. The heritability (h 2 of the degree of melanization was estimated by regression and analysis of variance. The estimates of h 2 were similar with both methods, indicating that the qualitative method could be particularly suitable for field work. The low estimates obtained for heritability may have resulted from the small sample size ( n = 7-18 broods, including the parents or from the allocation-priority hypothesis in which pupal color would be a lower priority trait compared to morphological traits and adequate larval development.

    The formation of Babesia ovis sporozoites in salivary gland cells of the vector tick Rhipicephalus bursa was studied by electron microscopy. The kinetics of B. ovis were found lying intracellularly on the second day after infestation (a.i.) of the ticks. The parasites enlarged rapidly losing all features of the motile form. Invaginations of the cell membrane initiated a fragmentation of this developmental stage. On the third day a.i the parasite (measuring 40 x 25 microns) was divided into numerous single membrane-bounded cytomeres, each provided with at least one lobed nucleus. On the fourth day a.i. sporozoite differentiation started at the periphery of the cytomeres, indicated by the appearance of several pellicle-bounded, exogenous protrusions into each of which a small portion of the nucleus was incorporated. Since the cytomeres lay very close together this differentiation occurred more by segmentation than by budding. Rhoptries and the so-called spherical body appeared in this developmental phase. Finally, the isolated, immature sporozoites lay in a granular matrix which contained remnants of the host cell cytoplasm. On the fifth day a.i. the sporozoites were fully developed, typically pear-shaped (2.8 x 1.2 microns) and provided with all characteristic structures of the invasive form.--This reproduction was compared to similar processes in other species of the Piroplasmia and the Haemosporina.

    Esen, Fatma; Tasdemir, Yücel; Vardar, Nedim

    Atmospheric PAH concentrations were determined in Gulbahce district of Bursa, Turkey between August 2004 and April 2005. Measured PAH concentrations were classified as heating and non-heating season samples. The concentrations of total PAHs in heating season were almost ten times higher than those in non-heating season. Diagnostic ratios and factor analysis results show that in the heating season traffic along with residential heating emissions heavily influence PAH concentrations. The plot of log Kp versus log PL0 for all the data set of heating and non-heating season samples gave significantly different slopes. The slope for the heating season samples (- 0.92) was steeper than the one for the non-heating season samples (- 0.78). The partitioning results for individual samples further indicated that slope values varied depending on air parcel trajectories. Air parcels traveled over water (either over the Black Sea or Aegean Sea) prior to arriving at the sampling site had less steep slopes. Partitioning of PAHs was also investigated by comparing experimentally determined Kp values with the results obtained both from octanol-based model ( Kp(Oct.)) and soot and octanol-based model ( Kp (Soot + Oct.)). Both models were useful in predicting the experimental Kp values. However, they did not explain the observed variability in the experimental Kp values.

    Synovial osteochondromatosis is an idiopathic benign metaplasia of the synovial membrane rarely found in an extra-articular bursa. We describe the case of a 55-year-old woman with synovial osteochondromatosis in the subacromial bursa mimicking calcific tendinitis. Plain radiographs showed a radiopaque mass over the middle facet of the greater tuberosity, suggesting calcific tendinitis. Sonography, however, showed a loose body in the subacromial bursa, and no evidence of calcification inside the rotator cuff. Copyright © 2013 Wiley Periodicals, Inc.

    We describe an unusual case of biliopancreatic fistula, free perforation, and subsequent abscess formation within the lesser peritoneal sac associated with intraductal papillary mucinous carcinoma (IPMC). A 71-year-old man presented with general fatigue and loss of appetite that had persisted for 1 month. Abdominal computed tomography (CT) revealed findings consistent with an intraductal papillary mucinous neoplasm (IPMN) of the pancreas, accompanied by abscess formation in the bursa omentalis. Gastrointestinal fiberscopy revealed a swollen papilla of Vater expanded by sticky mucus, and a communication between the pancreatic duct and bile duct was demonstrated by the injection of indigo carmine solution into the pancreatic duct. Percutaneous transhepatic abscess drainage (PTAD) was performed on the day of admission. After this procedure, the patient was managed for 1 month and supported nutritionally with glycemic control for diabetes mellitus. After admission, the patient had an episode of obstructive jaundice that was treated by retrograde biliary drainage. Pancreaticoduodenectomy with lymph node dissection was then performed. Pathological examination revealed IPMN with patchy, scattered carcinoma of the pancreatic head and uncinate process with the formation of a biliopancreatic fistula. Bile duct epithelium in the area of the biliopancreatic fistula demonstrated atypical papillary epithelium suggestive of tumor invasion.

    This paper integrates the Revised Universal Soil Loss Equation (RUSLE) with a GIS model to investigate the spatial distribution of annual soil loss and identify areas of soil erosion risk in the Uluabat sub-watershed, an important agricultural site in Bursa Province, Turkey. The total soil loss from water erosion was 473,274 Mg year(-1). Accordingly, 60.3% of the surveyed area was classified into a very low erosion risk class while 25.7% was found to be in high and severe erosion risk classes. Soil loss had a close relationship with land use and topography. The most severe erosion risk typically occurs on ridges and steep slopes where agriculture, degraded forest, and shrubs are the main land uses and cover types. Another goal of this study was to use GIS to reveal the multi-year urbanization status caused by rapid urbanization that constitutes another soil erosion risk in this area. Urbanization has increased by 57.7% and the most areal change was determined in class I lands at a rate of 80% over 25 years. Urbanization was identified as one of the causes of excessive soil loss in the study area.

    1979-10-01

    By ammonium sulfate fractionation and gel filtration an enzyme preparation which catalyzed NAD(+)-dependent L-lactate oxidation (10(-4) kat kg(-1) protein), as well as NADH-dependent pyruvate reduction (10(-3) kat kg(-1) protein), was obtained from leaves of Capsella bursa-pastoris. This lactate dehydrogenase activity was not due to an unspecific activity of either glycolate oxidase, glycolate dehydrogenase, hydroxypyruvate reductase, alcohol dehydrogenase, or a malate oxidizing enzyme. These enzymes could be separated from the protein displaying lactate dehydrogenase activity by gel filtration and electrophoresis and distinguished from it by their known properties. The enzyme under consideration does not oxidize D-lactate, and reduces pyruvate to L-lactate (the configuration of which was determined using highly specific animal L-lactate dehydrogenase). Based on these results the studied Capsella leaf enzyme is classified as L-lactate dehydrogenase (EC 1.1.1.27). It has a Km value of 0.25 mmol l(-1) (pH 7.0, 0.3 mmol l(-1) NADH) for pyruvate and of 13 mmol l(-1) (pH 7.8, 3 mmol l(-1) NAD(+)) for L-lactate. Lactate dehydrogenase activity was also detected in the leaves of several other plants.

    Full Text Available Avian infectious bronchitis virus (IBV is prevalent in all countries with intensive poultry flocks. This disease is characterised primarily by respiratory signs, but some IBV strains may also infect other organs such as the intestinal and urogenital tracts. The aim of this study was to characterise the histopathological lesions and tissue tropism of Iranian isolate IR/773/2001(793/B of avian infectious bronchitis virus in different organs of experimentally infected SPF chickens. Forty-two one-day-old, specific pathogen-free (SPF chicks were divided randomly into two groups (21 chicks to each group. At the age of 12 days, one group was inoculated intra-ocularly with 103 EID50 of the 793/B isolate, and the other was kept as the control group. Tissue samples were collected at 2, 4, 6, 8, 10 and 12 days post-inoculation (PI. The IBV virus was detected in the caecal tonsils and cloaca from the 2nd to the 12th day PI. The virus was also detected in the kidneys from days 4–10 PI and in the bursa of Fabricius from days 4–12 PI. The virus was detected in the trachea, lungs and thymus. The most obvious histopathological lesions were found in the trachea, kidney, lungs and bursa of Fabricius. Amongst the lymphoid tissues, histopathological changes were found most frequently in the bursa of Fabricius. The results of this study indicated that the 793/B serotype of IBV is unlikely to cause mortality, severe clinical signs or gross lesions in infected chickens, but its replication in some tissues including the bursa of Fabricius could render birds susceptible to other micro-organisms.

    To describe and validate a sonographically guided (SG) semimembranosus (SM) bursa injection technique in an unembalmed cadaveric model. Prospective, cadaveric laboratory investigation. Academic institution procedural skills laboratory. Ten unembalmed cadaveric thigh-knee-ankle-foot specimens from 4 male and 6 female donors ages 55-92 years (mean 76.2 years) with body mass indices of 15.4-31.8 kg/m(2) (mean 21.9 kg/m(2)). A single, experienced operator completed SG SM bursa injections in 10 unembalmed cadaveric knees using 3 mL of diluted colored latex. At a minimum of 2 days after the injection, co-investigators dissected the specimens to assess the distribution of latex with respect to the SM bursa. Injections were graded for accuracy as follows: accurate (all latex contained within the SM bursa), accurate with overflow (latex within the SM bursa and extending into regions other than the needle track), or inaccurate (no latex within the SM bursa). All 10 injections (100%) accurately placed latex within the SM bursa and resulted in proximal spread to at least the level of the knee joint. Eight of 10 injections (80%) demonstrated minimal (<1 mL) extrabursal flow without extension into the intra-articular space. No neurovascular injury occurred in any specimen. SG SM injections are feasible and accurate and may be considered for diagnostic and therapeutic injections in patients with suspected distal SM disorders.

    Impingement is a common cause of shoulder pain. Impingement mechanisms may occur subacromially (under the coraco-acromial arch) or internally (within the shoulder joint), and a number of secondary pathologies may be associated. These include subacromial-subdeltoid bursitis (inflammation of the subacromial portion of the bursa, the subdeltoid portion, or both), tendinopathy or tears affecting the rotator cuff or the long head of biceps tendon, and glenoid labral damage. Accurate diagnosis based on physical tests would facilitate early optimisation of the clinical management approach. Most people with shoulder pain are diagnosed and managed in the primary care setting. To evaluate the diagnostic accuracy of physical tests for shoulder impingements (subacromial or internal) or local lesions of bursa, rotator cuff or labrum that may accompany impingement, in people whose symptoms and/or history suggest any of these disorders. We searched electronic databases for primary studies in two stages. In the first stage, we searched MEDLINE, EMBASE, CINAHL, AMED and DARE (all from inception to November 2005). In the second stage, we searched MEDLINE, EMBASE and AMED (2005 to 15 February 2010). Searches were delimited to articles written in English. We considered for inclusion diagnostic test accuracy studies that directly compared the accuracy of one or more physical index tests for shoulder impingement against a reference test in any clinical setting. We considered diagnostic test accuracy studies with cross-sectional or cohort designs (retrospective or prospective), case-control studies and randomised controlled trials. Two pairs of review authors independently performed study selection, assessed the study quality using QUADAS, and extracted data onto a purpose-designed form, noting patient characteristics (including care setting), study design, index tests and reference standard, and the diagnostic 2 x 2 table. We presented information on sensitivities and specificities with

    Full Text Available The hemocyte composition of adults of Amblyomma cajennense (Fabricius, 1787 Koch, 1844 adults consisted of three basic cellular types: prahemocyte I (PR I, plasmatocyte (PL and spherulocyte (ES II. Among the ixodids observed (A. cajennense; A. dissimile Koch, 1844; Rhipicephalus sanguineus Latreille, 1806; Anocentor nitens (Neumann, 1897 Schulze, 1937; Boophilus microplus Canestrini, 1887 and Haemaphysalis sp. only A. cajennense was different in the adult hemolymph colour. It changed from amber to deep blue as the ixodid age advanced. This fact could be associated with the presence of hemocyanin in the hemolymph and points out the need to develop further investigations about the Ixodidae hemolymph pratein composition as well as the function of all the types found in it. This information could aid the studies on ticks control.

    Full Text Available Chickpea (Cicer arietinum L., is an important pulse food. During storage this commodity is severely attacked bybean beetle Callosobruchus maculatus (Fabricius resulting losses in quantity and nutritional quality. Research studies onrelative resistance of 12 chickpea genotypes to the attack of C. maculatus during storage were carried out. The genotypesmost tolerant to bruchids comprised CH-52/02 and B-8/03, whereas, the most susceptible reactions were apparent inCH-86/02 and CC-117/00. The moderate pest incidence was observed in CH-28/02, CH-4/02, CH-32/02, CH-31/02, CH-9/02,CM-772/03, B-8/02 and CM-628/03 genotypes. The tolerant genotypes exhibited hard and wrinkled seed coat, dark browncolour and small size grain. These characteristics demonstrated a significant harmful effect to pest appearance and graindamage. The vulnerable genotypes had soft and smooth seed coat, white seed colour and bigger grain size that causedvulnerability to C. maculatus. Based on the present investigation, chickpea genotypes CH-52/02 and B-8/03 deserve specialconsideration and may be recommended for relatively longer storage to achieve the goal of long term and sustainable pestmanagement strategies.

    Full Text Available The sublethal effects of diazinon, fenitrothion and chlorpyrifos on the functional response of predatory bug, Andrallus spinidens Fabricius (Hem.: Pentatomidae, a potential biological control agent, were studied on 5th-instar nymphs. The experiment was conducted in varying densities (2, 4, 8, 16, 32 and 64 of last instars larvae of Chilo suppressalis Walker (Lepidoptera: Pyralidae as prey at 25 ± 2 °C, 60% ± 10% relative humidity (RH and a photoperiod of 16:8 h (L: D. The results of logistic regressions revealed a type II functional response in the control and all insecticide treatments. Comparison of functional response curves revealed that tested insecticides markedly decreased the mean of preys consumed by A. spinidens. Among them, functional response curve of A. spinidens in chlorpyrifos treatment was significantly lower than the other treatments. In this study, application of insecticides caused a decrease in the attack rate and an increase in the handling time of exposed bugs compared with the control. The longest handling time (3.97 ± 0.62 and the lowest attack rate (0.023 ± 0.007 were observed in chlorpyrifos and fenitrothion treatments, respectively. The results suggested that the adverse effect of these insecticides on A. spinidens should be considered in integrated pest management programs (IPM.

    Tenoscopy of the navicular bursa has been recently introduced as a diagnostic and therapeutic treatment in cases of palmar foot pain syndrome. A deep digital flexor tendon transthecal approach was suggested in 1999, and the endoscopic technique has been reviewed. Smith and coworkers have recently reported good and promising results. An anatomic cadaver limb study was performed, and the endoscopic technique was evaluated. Subsequently, a 14-year-old Argentine mare, affected by palmar foot pain syndrome, was treated. Clinical data, MRI and endoscopic findings, and a 6-month follow-up evaluation are reported.

    Full Text Available In the present study we estimed the longevity and reproductive potential of Cochliomyia macellaria (Fabricius, 1775, in different densities of grouped pairs, as a function of time of collection. The study was divided into two phases and conducted in an incubator regulated at 27oC, 65±10% RH and 14 hours photoperiod. Forty and 20 pairs/replication were used, corresponding to the third and fourth generation originating from a laboratory colony. Egg masses were collected at 8:00 and 17:00 hours daily. The results obtained were influenced by the variables established. The ovipositing peak occurred 20 days after the emergence of females belonging to the third generation. This peak occurred earlier in fourth generation females, i.e., 11 days after imago emergence. These peaks corresponded to a total of 0,30 and 0,23g of egg masses, respectively. The survival curves for adults were estimated by the Weibull method.

    Full Text Available This project was aimed to evaluate immunostimulatory effects of three therapeutic substances in broilers suffering from infectious bursal disease (IBD. For this purpose, 150 chicks were divided into five equal groups i.e. A, B, C, D and E having 30 birds each. Group A, B, C and D were challenged with infectious bursal disease virus. There were three immunostimulatory treatments i.e. levamisole (group A, vitamin E (group B, and bursinex (group C. Groups D and E were untreated control. Bursa body weight index, histopathology of bursa of Fabricius, plasma cell counting in Harderian gland and estimation of antibody response against infectious bursal disease virus was recorded. Vitamin E played a major role in improving the condition of birds suffering from infectious bursal disease, as it showed increased bursa body weight index (BBIx, less histopathological lesions in bursa of Fabricius, increased number of plasma cells in Harderian gland and high antibody response in infectious bursal disease infected broilers as compared to levamisole and bursinex. Levamisole played a minor role in improving condition of birds, while bursinex did not seem to be much effective against infectious bursal disease virus in this study.

    This work presents the first identification of putative odorant-binding proteins (OBPs) from a member of the Pentatomidae, i.e. the brown stink bug Euschistus heros (Fabricius), an important pest of soybean in Brazil. Antennae from both sexes of E. heros adults (12 days old and unmated) were used to construct a cDNA library, from which two transcripts encoding putative E. heros OBPs (EherOBPs) were identified. The expression levels of EherOBP1 and EherOBP2 were found to be higher in male antennae than in female and there was difference in expression in legs, wings, and abdomens of the two sexes. The histolocalization of EherOBP1 and EherOBP2 transcripts in antennae also showed a sexual dimorphism in the chemoreception system, with different expression sites in the antennal segments between males and females, occurring predominantly at the base of the sensillum. The implications of these findings for stink bug chemoreception are discussed.

A diet consisting of decomposing horse flesh was used, and the relation of 1 larva/g diet was established. The development of the two species was done in pure and associated cultures. The association with Chrysomya albiceps influenced the post-embrionary development period and the weight of mature larvae of the C. megacephala, reducing their. Such weight decrease, along with the predation of larvae of C. megacephala larvae, yelded a decrease in survival in all of the stages. Larvae of this species showed an increase in its weight when associated with Cochliomyia macellaria. The native species responded to the association by reducing its body weigth and its viability. This association doesnt influence the duration of post-embrionary development.

    Maggot debridement therapy (MDT) consists on the intentional and controlled application of sterilized larvae of the order Diptera on necrotic skin lesions with the purpose of cleaning necrotic tissue and removing pathogenic bacteria. During MDT, a marked antimicrobial activity has been reported in literature specially associated with antibacterial substances from Lucilia sericata (Meigen); however, regarding Cochliomyia macellaria (Fabricius), little is known. This study aimed to evaluate in vitro inhibition of bacterial growth of Pseudomonas aeruginosa and Staphylococcus aureus in contact with excretions and secretions (ES) from C. macellaria larvae. Larval ES were extracted in sterile distilled water and divided in three groups: ES, containing 400 μL of autoclaved ES; ES+BAC, containing 400 μL of autoclaved ES+0.5-μL bacterial inoculum; and CONT-BAC, containing 400 μL of sterile distilled water +0.5 μL of bacterial inoculum. Aliquots of each experimental group were plated by spreading onto Petri dishes. Seedings were made at 0, 1, 2, 4, and 12 h after the extraction of ES. In ES+BAC groups, inhibition of S. aureus was verified between times 1 and 2 h and P. aeruginosa was inhibited between 0 and 4 h. There was no growth observed in any ES group. In the CONT-BAC groups, the number of colonies from time 4 h became countless for S. aureus and decreased for P. aeruginosa. As reported in the literature, we note here that ES have excellent bactericidal activity for both gram-positive and gram-negative bacteria, and this study shows for the first time the action of the bactericidal activity of exosecretions of C. macellaria against S. aureus and P. aeruginosa.

The first part was a single-blind prospective study. The second part was a prospective cohort study. An academic institution procedural skills laboratory and outpatient clinic. The first part of the study involved 1 cadaveric specimen. The second part of the study involved 20 asymptomatic subjects. The mean age of the subjects was 28 years, and the mean (standard deviation) body mass index was 23.2 ± 2.8 kg/m(2) (minimum, 18.3 kg/m(2); maximum, 29.5 kg/m(2)). In the first part of the study, a single operator completed bilateral ultrasound-guided ischial bursa injections in an unembalmed cadaveric specimen by using diluted colored latex. In the second part of the study, ultrasound was used in 20 asymptomatic volunteer subjects (10 men and 10 women) to measure the distance from the lateral edge of the ischial tuberosity to the sciatic nerve. The injections were graded for accuracy as follows: accurate (all injectate contained within the ischial bursa), accurate with overflow (injectate within the ischial bursa but also located in adjacent structures other than the needle track), or inaccurate (injectate not within the ischial bursa). The second part of the study measured the distance from the ischial tuberosity to the sciatic nerve with subjects in 2 different positions (prone and side lying with the tested hip flexed to 90°). Postinjection cadaveric dissections revealed that both ultrasound-guided injections accurately placed liquid latex within the ischial bursae. There was no evidence of injury to surrounding neurovascular structures. Among asymptomatic volunteers, the average distance between the ischial tuberosity and the sciatic nerve increased from 28.4 mm (range, 20.5-38.9 mm) in the

Toxicity assessment to ensure M. discolor adults were not sensitive to Cry1Ab or Cry1Ac protein independent from the pollen background, M. discolor adults were fed with an artificial diet containing Cry1Ac, Cry1Ab or both protein approximately 10 times higher concentration than in Huahui 1 rice pollen. No difference was detected for any of the life-table parameters tested between Cry protein-containing and pure diet. Artificial diet containing E-64 (N-(trans-Epoxysuccinyl-L-leucine 4-guanidinobutylamide was included as a positive control. In contrast, the pre-oviposition and fecundity of M. discolor were significantly adversely affected by feeding on E-64-containing diet. In both bioassays, the uptakes of Cry protein by adult M. discolor were tested by ELISA measurements. These results indicated that adults of M. discolor are not affected by Cry1Ab- or Cry1Ac-expressing rice pollen and are not sensitive to Cry protein at concentrations exceeding the levels in rice pollen in Huahui1. This suggests that M. discolor adults would not be harmed by Cry1Ac/Cry1Ab rice if Bt rice Huahui 1 were commercialized.

    Objective: To evaluate the diagnostic values of the superior subscapularis recess sign in patients with shoulder adhesive capsulitis. The sign consists in evaluating in MRI of the shoulder the presence of fluid distension of the bursa in the superior subscapularis recess. Materials and methods: We evaluated MRI of 165 shoulders in 48 consecutive patients with a diagnosis of shoulder adhesive capsulitis in the freezing phase (group I), in 49 short-wide superior cuff tear (group II) and in 65 controls (group III) between 2010 and 2013. On the T2 weighted images, we evaluated the presence of an high intensity signal within the superior subscapularis recess, consistent with fluid distension of the bursa. Results: The sign was found in 43/48 patients (89.58%) with shoulder adhesive capsulitis in 3/49 (6.12%) patients with superior cuff tear and in 1/65 controls (1.53%) (p < 0.001). The mean diagnostic values were: sensibility 0.91; specificity 0.96–0.98; positive predictive value 0.93–0.97; negative predictive value 0.92–0.94; likelihood ratios for an abnormal test result 15.16–60.6; likelihood ratios for a normal test result 0.086–0.095. Conclusion: For the orthopedic surgeon or the clinician, the sign is useful to confirm in MRI the clinical diagnosis of shoulder adhesive capsulitis; accordingly, the radiologist should describe and relate this sign to the pathology in the report, looking eventually for further typical sign of shoulder adhesive capsulitis.

The mean diagnostic values were: sensibility 0.91; specificity 0.96-0.98; positive predictive value 0.93-0.97; negative predictive value 0.92-0.94; likelihood ratios for an abnormal test result 15.16-60.6; likelihood ratios for a normal test result 0.086-0.095. For the orthopedic surgeon or the clinician, the sign is useful to confirm in MRI the clinical diagnosis of shoulder adhesive capsulitis; accordingly, the radiologist should describe and relate this sign to the pathology in the report, looking eventually for further typical sign of shoulder adhesive capsulitis.

    The European wasp, Vespula germanica (Fabricius) (Hymenoptera: Vespidae), is of Palaearctic origin, being native to Europe, northern Africa and Asia, and introduced into North America, Chile, Argentina, Iceland, Ascension Island, South Africa, Australia and New Zealand. Due to its polyphagous nature and scavenging behaviour, V. germanica threatens agriculture and silviculture, and negatively affects biodiversity, while its aggressive nature and venomous sting pose a health risk to humans. In areas with warmer winters and longer summers, queens and workers can survive the winter months, leading to the build-up of large nests during the following season; thereby increasing the risk posed by this species. To prevent or prepare for such unwanted impacts it is important to know where the wasp may be able to establish, either through natural spread or through introduction as a result of human transport. Distribution data from Argentina and Australia, and seasonal phenology data from Argentina were used to determine the potential distribution of V. germanica using CLIMEX modelling. In contrast to previous models, the influence of irrigation on its distribution was also investigated. Under a natural rainfall scenario, the model showed similarities to previous models. When irrigation is applied, dry stress is alleviated, leading to larger areas modelled climatically suitable compared with previous models, which provided a better fit with the actual distribution of the species. The main areas at risk of invasion by V. germanica include western USA, Mexico, small areas in Central America and in the north-western region of South America, eastern Brazil, western Russia, north-western China, Japan, the Mediterranean coastal regions of North Africa, and parts of southern and eastern Africa.

    Full Text Available Lygus rugulipennis Poppius and Liocoris tripustulatus Fabricius (Heteroptera: Miridae are pests of glasshouse cucumber and sweet pepper crops respectively. L. rugulipennis has a wide range of foodplants, but L. tripustulatus is specialised with very few food plants. We report behavioural assessments to investigate whether either species exhibits a preference for salad over wild hosts, and whether the role of olfaction and vision in response to cues from host plants can be distinguished. Olfactory responses to leaves were tested in choice chambers. L. rugulipennis was presented nettle (wild host and a salad leaf of cucumber or sweet pepper, where the salad leaves had higher nitrogen content. L. tripustulatus was tested with nettle and sweet pepper of two different nitrogen contents. Female L. rugulipennis spent more time on the cucumber salad host, and chose it first most often, but males showed no preference. Neither sex discriminated between sweet pepper or nettle leaves, but males made more first contacts with sweet pepper. Neither sex of L. tripustulatus discriminated between sweet pepper and nettle leaves when the sweet pepper had higher nitrogen. When the plant species contained equivalent nitrogen both sexes spent more time on nettle. There was no difference in first choice made by either sex. When visual stimuli were available, and leaves had equivalent nitrogen, L. rugulipennis showed no preference and L. tripustulatus preferred nettle leaves. We conclude that the generalist L. rugulipennis has the ability to use remote olfactory cues for host choice whereas the specialist L. tripustulatus relies mainly on contact chemosensory and gustatory cues.

    2015-09-01

    Calcifying tendinitis of the shoulder is a common condition characterized by the deposition of calcium, predominantly hydroxyapatite crystals, in the rotator cuff. A rare complication of this condition is the migration of calcium deposits from tendons, usually the supraspinatus, into the subacromial-subdeltoid bursa or into the humeral greater tuberosity. These complications are responsible for intense acute shoulder pain and functional disability. Patient anamnesis and clinical symptoms must be considered to make the diagnosis, but imaging, particularly sonography, is often necessary, showing a typical presentation related to the locations of calcium deposits. We present sonographic and other imaging features of subacromial-subdeltoid bursitis and humeral osteitis related to the migration of calcium.

    The Eocene aged Topuk Granitoid exposing in the Tavşanlı Zone at south of the Izmir-Ankara Suture Zone is one of the granitoids which were formed as a result of collision of the Anatolide-Tauride block with the Sakarya continent in the late Cretaceous. Nearly east-west extending, elliptical shaped Topuk Granitoid was intruded into the Paleozoic and Mesozoic metamorphites and upper Cretaceous ophiolitic rocks. The intrusion is in granodiorite composition and contains spherical/ellipsoidal mafic microgranular enclaves (MME) with composition of monzodiorite to monzogabbro. The granitoid which contains xenoliths is frequently cut by porphyritic granodiorite, granite aplite and quartz dikes at the margins. Topuk Granitoid is represented by an I-type pluton with medium to high K calc-alkaline affinity and metaluminous melt composition. Ocean ridge granite (ORG) normalized element distributions show that the granitoid, dikes and MME's have similar patterns. A significant enrichment of LIL (Rb, Ba, K, Th and Sr) elements and relatively depletion of HFS (Ta, Nb, Ce, Hf, Y, Zr and Ti) elements are indicative of formation from hybrid magma in a subduction environment. In tectonic discrimination diagrams (Ta -Yb and Rb-Y+Nb), samples of the Topuk Granitoid are plotted into the volcanic arc granite (VAG) field which is characteristic for the post collision granites. The results of mineral chemistry show that plagioclases are in oligoclase-andesine (An20-49) composition, amphiboles are of magnesio-hornblende and biotites are of Fe-Mg-biotite composition. In the Al2O3-FeO-MgO diagram biotite minerals are accompanied by amphibole and other ferromagnesian minerals and represent biotites of calc-alkaline orogenic zones. Calculations based on the hornblende-barometer indicate that the calc-alkaline magma was crystallized under pressure of 2-6 kbars (mean=4 kbars) and at depth of 7-20 km (mean=12 km). The whole-rock and mineral chemistry data show that the Topuk Granitoid was formed

    Synovial chondromatosis is characterized by benign synovial proliferation that leads to chondral or osteochondral foci formation. In this case report, a right-handed female suffered from progressively worsening pain and limited mobility of forward elevation, abduction and external rotation in her right shoulder. A shoulder arthroscopy was conducted, during which, thickened bursal synovium and several loose bodies were observed, associated with bursal side tear of rotator cuff. A thorough synovectomy, subacromial debridement and acromioplasty were conducted. The pathological findings were consistent with synovial chondromatosis. After systematic rehabilitation, the patient had relief of shoulder pain and full range of motions in 14-months follow-up. Case report, Level IV.

    Lipoma arborescens is a rare intra-articular disease that is usually monoarticular and is characterized by extensive proliferation of the synovial villi and hyperplasia of the subsynovial fat. The synovial tissue is progressively replaced by mature fat cells in the synovial membrane. The present study reports a case of a rare condition of lipoma arborescens that was simultaneously intra-articular (glenohumeral joint) and in the subacromial-subdeltoid bursa, in association with a torn supraspinatus tendon. The clinical, histological and radiographic presentations and treatment are discussed here. The description of this case includes radiographic and magnetic resonance evaluations and pathological examination. Although lipoma arborescens is a rare condition, it should be taken into consideration in cases presenting synovial hyperproliferation and synovial fat replacement.

    This short paper aims to detect spatiotemporal detection of land use/land cover change within Karacabey Flooded Forest region. Change detection analysis applied to Landsat 5 TM images representing July 2000 and a Landsat 8 OLI representing June 2017. Various image processing tools were implemented using ERDAS 9.2, ArcGIS 10.4.1, and ENVI programs to conduct spatiotemporal change detection over these two images such as band selection, corrections, subset, classification, recoding, accuracy assessment, and change detection analysis. Image classification revealed that there are five significant land use/land cover types, including forest, flooded forest, swamp, water, and other lands (i.e. agriculture, sand, roads, settlement, and open areas). The results indicated that there was increase in flooded forest, water, and other lands, while the cover of forest and swamp decreased.

    Full Text Available Benjamin Graham, also known as the “father of value investing” proposed that investment in the stock exchange can be a safe endeavor while receiving gains that outperform the market if the investor makes carefully thought out purchases. This study aims to determine if the use of some of Benjamin Graham’s stock selection criteria is able to generate returns that are significantly greater than the returns in the stock exchange of Malaysia, particularly, the comprehensive FTSE Bursa Malaysia EMAS Index. This study collected secondary data regarding fundamentals of companies listed in the FTSE Bursa Malaysia EMAS Index from the year 2000 to 2009. Five criteria were set up in this research based on one or a combination of price-to-earnings ratio, price-to-book value, current ratio and dividend yield. The listed companies were screened using those criteria. An equally weighted portfolio was created using the screened companies and their one-year and two-year returns calculated. The returns were compared to the market return. Hypotheses of this research were tested using t-test statistic to determine the significance of the data. This research found that most of the screening criteria used generated returns that were higher than the market return in almost every year they were tested in. Benjamin Graham’s stock selection criteria although have been conceived over 80 years ago is still applicable today in the Malaysian market. Further research can be conducted with different criteria with varying holding periods and in different markets.

    The aim of this study is to describe the epidemiological and clinical aspects of patients who applied to the Bursa Nilufer Tuberculosis Dispensary by investigating the trends in epidemics over three decades. In this retrospective observational study, the records of all tuberculosis cases (1630 patients) treated in the last 30 years (1985-2014) at the Bursa Nilufer Tuberculosis Dispensary were examined and statistically analyzed. Males comprised 65.2% of the patients. The ages of the patients ranged from 1 to 87 years, and the mean age was 37.4 (95% CI: 36.6-38.2). Among the cases, 86.7% were new infections and 74.1% were pulmonary tuberculosis. In the last decade, the education level, the percentage of patients who had received a BCG vaccination, the proportion of women and active employees among them increased (p<0.05), while it decreased among men (p<0.05). Clinical symptoms accompanying TB such as weakness, anorexia, weight loss, and cough, decreased to a statistically significant degree (p<0.05). In the last decade, the mortality rate was 3.6% and increased compared with previous decades (p<0.05). Mortality was higher among patients who were elderly, male, did not have a BCG scar or had a chronic disease (p<0.05). This study adds information about the change of TB epidemics in Turkey in the last 30 years. Further studies are needed to determine the risk factors associated with tuberculosis mortality and to evaluate the effectiveness control programs of this disease.

    2008-09-01

    The purpose of this study was to assess the distance for a standard needle to reach the subacromial bursa through 3 commonly used approaches. Thirty patients without associated rotator cuff tears underwent arthroscopic evaluation of the shoulder. The bursa was entered without shaving or altering of the bursa. By use of standard arthroscopic portals, a spinal needle was inserted from an anterior, lateral, and posterior position and measured to define the distance to the subacromial bursa from the skin. The mean distance with anterior needle placement was 2.9 +/- 0.6 cm. The mean distance with lateral needle placement was 2.9 +/- 0.7 cm. The mean distance with posterior needle placement was 5.2 +/- 1.1 cm. The mean body mass index for the group of patients was 27.5. The minimum was 18.7, and the maximum was 42.8. The distance to the subacromial bursa from the anterior and lateral approaches appears to be consistent and within reach of a standard 22- or 25-gauge needle. The distance to the subacromial bursa from a posterior approach appears to be almost double that of the anterior and lateral approaches and may not be reachable by standard 22- and 25-gauge needles in all patients. There appears to be no correlation between distances to the subacromial bursa from the anterior, lateral, or posterior approaches and the patient's body mass index. Given the relative distances measured to the subacromial bursa from the anterior, lateral, and posterior positions, clinicians may choose a longer needle to improve the accuracy of placement when approaching the subacromial bursa from a posterior position. Use of a standard-length needle will provide reasonable accuracy from the anterior and lateral positions.

    Full Text Available Objective: In this study, antimicrobial activities of an ethanol extract of Tribulus terrestris aloneand in combination with Capsella bursa-pastoris and Glycyrrhiza glabra were examined in vitro against six pathogens namely Streptococcus mutans, Streptococcus sanguis, Actinomyces viscosus, Enterococcus faecalis Staphylococcus aureus, and Escherichia coli. Materials and methods: Antibacterial activities of the extracts were examined using disc and well diffusion methods and the minimum inhibitory concentration (MIC and minimum bactericidal concentration (MBC of ethanol extracts were determined against these microorganisms using agar and broth dilution methods. Chlorhexidine was used as positive control. Results: Tribulus terrestris extract exhibited good antibacterial activity against all bacteria. Antibacterial activity of mixed extract was evaluated and exhibited that mixed extract was more effective against all bacteria than any of the cases alone which indicates the synergistic effect between these three extracts (p˂0.05. No strain showed resistance against these extracts. In agar dilution, Tribulus terrestris exhibited MIC values ranging from 35.0 to 20.0 mg/ml and mixed extract showed MIC values ranging from 12.5 to 5.0 mg/ml. The results of broth dilution method were consistent with the findings of the agar dilution method. Conclusion: This in-vitro study was a preliminary evaluation of antibacterial activity of the plants. It provided scientific evidence to support uses of T. terrestris and its mixture with C. bursa-pastoris and G. glabra for the treatment of oral infections. In-vivo studies are also required to better evaluate the effect of these extracts.

    Full Text Available Chemoreception is a key feature in selection of host plant by phytophagous insects, and odorant-binding proteins (OBPs are involved in chemical communication of both insects and vertebrates. The legume pod borer, Maruca vitrata Fabricius (Lepidoptera: Crambidae is one of the key pest species of cowpea and widely distributed throughout tropical and subtropical regions, causing up to 80% of yield loss. In this study, we investigated the electrophysiological responses of female M. vitrata to floral volatiles from V. unguiculata. Seventeen electroantennogram-active compounds were identified from floral volatiles of V. unguiculata by coupled gas chromatography-electroantennography (GC-EAD and gas chromatography-mass spectrometry (GC-MS. Then, we cloned two novel full-length GOBP genes (MvitGOBP1 and MvitGOBP2 from the antennae of M. vitrata using reverse transcription PCR. Protein sequence analysis indicated that they shared high sequence similarity with other Pyralididae insect GOBPs and had the typical six-cysteine signature. Real-time PCR analysis indicated that MvitGOBP1-2 mRNA was highly expressed in the antennae of female adult with several thousands-fold difference compare to other tissue. Next, the recombinant MvitGOBP1-2 was expressed in Escherichia coli and purified using Ni ion affinity chromatography. Fluorescence binding assays demonstrated that MvitGOBP1-2 had different binding affinities with 17 volatile odorant molecules including butanoic acid butyl ester, limonene, 4-ethylpropiophenone, 1H-indol-4-ol, butanoic acid octyl ester and 2-methyl-3-phenylpropanal. In the field trapping experiment, these six floral volatiles could effectively attract female moths and showed significant difference compared with the blank lure. These results suggested that MvitGOBPs and the seventeen floral volatiles are likely to function in the olfactory behavior response of female moths, which may have played crucial roles in the selection of oviposition

The flies were maintained at 30ºC, from egg until mature larvae spontaneously abandoned the diet. They were then transfered to a climatized chamber at 27ºC. The larvae and pupae viability and the weight of the mature larvae were significantly inferior, when a diet based on meat broth was used, even though the larvae period was significantly increased with this diet. This type of diet did not charge the time of development of the pupae. The inoculation of the egg mass directly over the diet was recommend, instead of the technique in which the egg masses are transfered to humid filter paper, followed by the handling of the recently ecloded larvae.

    Full Text Available The possible dissimilitudes relating to the duration of the egg incubation period and larval stage of Cochliomyia macellaria (Fab., 1775 from offsprings of females from larvae with and without pigmentation on Malpighi tubules, morphotype 1 and 2, respectively, was questioned. The experiment was conducted in climatized chamber regulated at 30ºC, 65±10% RH and 14 hour photophase. No significant difference was observed on average duration of first and second larval instars berween the two morphotypes, taking into account not only the conventional interpretation for the reading of different development phases of the larval stages (morphotype 1:11.0 and 11.9 hours and morphotype 2:11.7 and 12.7 hours for first and second instars, respectively, but also the reading made through the interpretation preconized by Snodgrass & Hinton (morphotype 1:10.3 and 9.6 hours and morphotype 2:9.8 and 10.8 hours for the first and second instars, respectively. The incubation period was significantly longer for eggs posited by females from non-pigmented larvae.

    Full Text Available Mahakam Delta area, which is situated in Kutai Kartanegara Regency, has become a pond center that gives a significant contribution to shrimp export of East Kalimantan Province. Pond-produced shrimps, however, do not always accord to the intention of cold storage companies at expected price. The companies even sometimes reject the request due to poor quality of the product. The decreasing shrimp quality may be due to maintenance process by the pond farmers as well as the improper collectors. In the other hand, importing countries have decided more and more restricted requirements for the imported fishing products. This study was held in Muara Jawa, Anggana, and Muara Badak Districts using techniques of data collection of in-depth interview with twelve respondents. In order to improve shrimp quality, farmers or the producers have to formulate a strategy towards the improvement of the post harvest shrimps from the pond using an Analytical Hierarchy Process (AHP. Results of the AHP consist of as follows: (1 application of pond shrimp post harvest technology and improvement of facilities and accommodation that support the quality improvement of the pond shrimps, (2 human resource quality improvement of pond farmers, collectors, and field instructors, (3 development of pond culture by applying best practices principle and local policies in order to improve the quality of the pond shrimps, and (4 improvement of interagency coordination, monitoring, and evaluation to enhance the pond shrimp quality

    Full Text Available Blowflies use discrete and ephemeral substrates to feed their larvae. After they run out of food, the larvae begin to disperse in order to find adequate places for pupation or additional food sources, a process named post-feeding larval dispersion. Some important aspects of this process were studied in a circular arena allowing the combined radial post-feeding dispersion from the center of the arena of C. albiceps and C. megacephala larvae. To determine the location of each pupa, the arena was divided in 72 identical sections starting from the center. The distance from the center, the depth and weight of each pupa were evaluated. Statistical tests were done to verify the relation between weight, depth and distance for pupation. From the total an average of 976 larvae released (488 for each species were collected considering both experiments 456 C. megacephala pupae and 488 of C. albiceps. This demonstrates that C. albiceps probably preyed on 32 C. megacephala larvae during post-feeding dispersion. The study of this dispersion process can be used to estimate the postmortem interval (PMI of human cadavers in legal medicine.As moscas- varejeiras utilizam-se de substratos discretos e efêmeros para alimentar suas larvas.

    After going unreported in the northwestern Atlantic Ocean for 18 years (1988 to 2006), the Asian tiger shrimp, Penaeus monodon, has recently reappeared in the South Atlantic Bight and, for the first time ever, in the Gulf of Mexico. Potential vectors and sources of this recent invader include: 1) discharged ballast water from its native range in Asia or other areas where it has become established; 2) transport of larvae from established non-native populations in the Caribbean or South America via ocean currents; or 3) escape and subsequent migration from active aquaculture facilities in the western Atlantic. This paper documents recent collections of P. monodon from the South Atlantic Bight and the Gulf of Mexico, reporting demographic and preliminary phylogenetic information for specimens collected between North Carolina and Texas from 2006 through 2012. The increased number of reports in 2011 and 2012, ranging from 102 mm to 298 mm total length, indicates that an adult population is present in densities sufficient for breeding, which is indicative of incipient establishment. Based on these reports of P. monodon, its successful invasion elsewhere, and its life history, we believe that this species will become common in the South Atlantic Bight and Gulf of Mexico in less than 10 years. Penaeus monodon is an aggressive predator in its native range and, if established, may prey on native shrimps, crabs, and bivalves. The impacts of an established P. monodon population are potentially widespread (e.g., alterations in local commercial fisheries, direct and indirect pressures on native shrimp, crab and bivalve populations, and subsequent impacts on the populations of other predators of those organisms) and should be considered by resource managers. The impacts of P. monodon on native fauna and the source(s) or vector(s) of the invasion, however, remain unknown at this time.

    Full Text Available White spot syndrome virus (WSSV has caused mass mortality on tiger shrimp (Penaeus monodon culture and adversely affects prawn industry worldwide including Indonesia. It is well known that the protein structure of WSSV plays an important role in the virus infection and morphogenesis process. A viral protein structure called VP-15 is located in the nucleocapsid of virion virus. The protein structure involves in the life cycle of WSSV in host cells. A gene encoding VP-15 could be involved in constructing the RNA interference (RNAi, so it is needed to isolate and characterize for RNAi technology purpose. The study was aimed to isolate and characterize the VP-15 from the infected WSSV tiger shrimp. The characterization of VP-15 was undertaken through assessment of nucleotide sequence, amino acid deduction, alignment nucleotide/protein searches using Genetyx and BLAST program, and dendrogram construction analysis. The results showed that VP-15 was successfully isolated in form of ORFDNA with a fragment size of 243 bp. The phylogenetic tree analysis revealed three clusters corresponding to the time (year of isolates collection. The VP-15 consisted of 80 amino acids, two start codons (ATG, one stop codon (TAA, and one Kozak context (AAAATGG. Hydrophilic amino acid was the highest composition (44.2%, followed by neutral (31.2% and hydrophobic (24.6% amino acid groups. The VP-15 was rich in amino acid of lysine (21.3%, arginine (22.9% and serine (24.6%. The successful isolation of VP-15 is a very important step in providing a basic yet suitable material in constructing the dsRNA vaccine to control shrimp diseases in aquaculture.

    Full Text Available Habitat ecology and food and feeding of the herring bow crab, Varuna litterata of Cochin Backwaters, Kerala, India were investigated for a period of one year (April 2011-March 2012. Among the 15 stations surveyed, the crabs were found to occur only in 4 stations, which had a close proximity to the sea. Sediment analysis of the stations revealed that the substratum of these stations is sandy in nature and is rich in organic carbon content (0.79% to 1.07%. These estuarine crabs is euryhaline and are found to be distributed in areas with a sandy substratum, higher organic carbon content and more tidal influx. The stomach contents analysis of crabs examined showed that their diet included crustacean remains, plants, sand and debris, fishes, miscellaneous group and unidentified matter. In adults and sub-adults, crustaceans formed the dominant food group, while in juveniles, sand and debris formed the dominant group. From the present study, V. litterata was found to be a predatory omnivore capable of ingesting both animal and plant tissues.

    The fat body cells of Pachycondyla (=Neoponera) villosa are disposed in a single layer between the cuticle and the digestive tract, forming a group of cells enclosed by a thin membrane. Histological studies have revealed three different cellular types: trophocyte (more abundant), urate, (located among the trophocytes), and oenocyte (the scarcest), usually observed laying near the cuticle. Histochemically, the trophocytes showed a positive reaction for basic proteins in the nucleus and cytoplasm, as well as a strong positive reaction in the cytoplasmic granules. The test for carbohydrates showed a strong positive reaction throughout the cytoplasm, while the test for lipids was positive for the cytoplasmic vesicles. The urate cells showed a positive reaction for basic proteins in the nucleus and in the areas of the cytoplasm surrounding the vesicles. These cells did not react to the PAS test or to Sudan Black B. The oenocytes showed a weak positive reaction to PAS and a strong positive reaction to Sudan Black B and Mercuric-bromophenol Blue.

    Full Text Available Movement patterns of the spiny lobster Palinurus elephas were determined from 389 individuals (total tagged 5666 tag-recaptured inside a no-take area of the central western Mediterranean and its surrounding zone. High site association and limited movements in tagged lobsters was observed; 60.4% of lobsters moved less than 2 km from the centre of the area (site of release. No clear relationship between lobster movement pattern and sex or size was observed; however, it seemed that the largest males and females tended to be more resident, thus contributing to the rebuilding of the biomass of local lobsters. Most lobsters undertook migrations in the southwest direction. The increased availability of shelters and food towards the southwest could have contributed to the lobsters’ movement. The results of our research indicate that the small size of the protected area and the scale of the movement exhibited by tagged lobsters allows a proportion of the lobster population to move out of the protected area and become susceptible to capture in the adjacent fishery.

    Full Text Available Hypopharyngeal glands of honeybee are age-dependent structures that change with the size of acini and are correlated with various social behaviors. The histochemical structure of Apis cerana and A. mellifera worker hypopharyngeal glands in four different developmental stages wes stained with ninhydrin Schiff's and periodic acid Schiff's reagents (PAS for localization of proteins and carbohydrates, respectively, and examined with light microscopy. Nurse bees of both honeybee species had significantly larger glands as compared to guards and forgers, but there were no statistically significant differences between these two species after accounting for caste. Gland protein concentration increased progressively in nurse bees, and this was correlated with the appearance of enriched protein granules in the cytoplasm. In addition, the hypopharyngeal gland protein concentration of A. mellifera was higher than that of A. cerana even though gland size was not significantly different between species. However, gland size was shown to have decreased progressively in foragers and guards.

    The biodiversity of the European termite Kalotermes flavicollis is here studied through the analysis of mitochondrial (303 bp of control region and 912 bp of COI/tRNA(Leu)/COII) and nuclear (five microsatellite and 20 Inter-SINE loci) markers on 18 colonies collected in Southern France, Corsica, Sardinia, peninsular Italy, the Balkans and Greece. Different statistical analyses (Bayesian phylogenetic analysis,parsimony network, F-statistics, PCA) were performed. Mitochondrial sequences produced an unresolved polytomy including samples from peninsular Italy, Balkans and Greece, and three main clades: southern France, Corsica-Sardinia and Portoscuso(SW Sardinia). Nuclear markers confirm these data, further highlighting a more significant divergence at the regional scale. The results obtained for the peri-Tyrrhenian area agree with major paleogeographic and paleoclimatic events that shaped the biodiversity of the local fauna. K. flavicollis biodiversity and its phylogeographic pattern are also evaluated in the light of the data available for the other native European termite taxon (genus Reticulitermes), in order to produce a more complete scenario of the Mediterranean. In the area comprised between southern France and Italy, the degree of diversity is similar; however, in the eastern area, while K. flavicollis is differentiated only at the population level, the genus Reticulitermes comprises at least six entities of specific and/or subspecific level. This discrepancy may be explained by taking into account the different evolutionary histories of the two taxa.

In terms of the numbers of larvae and nymphs recovered, O. cuniculus was the best host species. The modal day for drop-off of larvae and nymphs was day three for the mammal hosts, but variable in the birds. We conclude that adult A. cajennense have a strong degree of specificity due to the fact that the tick failed to complete its life cycle on any of the evaluated hosts. The immature stages, on the other hand, showed a low level of specificity, most especially in the larval stage, indicating the existence of secondary hosts which probably serve as dispersers in the wild. The results also indicated a variable drop-off rhythm for larvae and nymphs in two periods, diurnal (6-18 hr and nocturnal (18-6 hr, which differed depending upon the host.

    Full Text Available Abstract Trypoxylon is a genus of solitary crabronid wasps whose population genetics is poorly known. The purpose of the present study was to investigate the genetic variation and differentiation among five populations of Trypoxylon albitarse, a species widely distributed throughout the Neotropics, with records from Panama to northern Argentina. Eight species-specific microsatellite loci were used for genotyping 96 adult wasps (one female per nest sampled at five sites in Brazil. The analysis of allelic richness and private alleles indicated high genetic diversity in the populations sampled. Pairwise comparisons using the Fst and Dest indices revealed significant differentiation for all, but one pair of populations. Fst, Dest, AMOVA and assignment test values pointed to inter-population differentiation. Additionally, the analysis of population structure using Bayesian and PCA methods characterized two alternative genetic groups. The Mantel test indicated no correlation between genetic and geographic distances. Despite evidence of considerable dispersal capacity for T. albitarse, the data indicate low to moderate population structuring in this species.

    Full Text Available Cochliomyia macellaria is of medical and veterinary interest, because it is an enteropathogen vector and causes secondary miyasis, and low cost diets are needed that maintain rearing quality of this species. The objective of this study was to assess a chicken gizzard diet, compared to beef, in the post-embrionic development of C. macellaria. Forty neolarvas (3rd generation were transferred to 80g diets (four replications/treatment. The body mass of the mature larvae was recorded and the larvae were transferred to test tubes, kept at T 30ºC day/28ºC night, RH 70±10%, 12 hours light period, and observed daily. There was a significant difference between the body mass of larvae reared on the chicken gizzard (0.067g and beef (0.062g diets. There was no significant difference between the mean duration in days of the larval (4.00; 4.17, pupa (4.09; 4.04 and neolarva to adult (8.07 and 8.16 stages based on the gizzard and beef diets, respectively. The mean larval, pupa and total viability (> 85% did not differ statistically by the Student’s t test (at 5% significance. There was no deviation in the sex ratio and no abnormality was observed in the adults. The results suggest that the chicken gizzard diet is an efficacious and cheap alternative for rearing C. macellaria in the laboratory.

    Osteochondroma is the most common benign bone tumour present multiple hereditary exostosis (HME). Scapular osteochondroma associated with pain and bursitis is rarely reported in literature. Here, we describe a 49-year-old male with the diagnosis of HME who was admitted to the Department of Thoracic Surgery with a painful and rapidly enlarging mass behind the left scapula. Computed tomography and magnetic resonance imaging indicated a large bursa formation associated with chest wall mass. Pre-operatively, the mass was diagnosed as osteochondroma and resected. Pathological findings confirmed that mass was a large bursa formation due to scapular osteochondroma without any evidence of malignancy. Osteochondroma should be considered in differential diagnosis of chest wall tumours located at this specific site. We discuss this rare complication of HME and emphasize the importance of early diagnosis and differentiation from malignant transformation of osteochondroma.

    Full Text Available Abstract The aim of this study was to evaluate the effect of phytogenic additives and glutamine plus glutamic acid, associated or not, on histomorphometry of bursa of Fabricius and small intestine, oocyst count and lesion scores, and carbon turnover of duodenal mucosa of broiler chickens infected with Eimeria acervulina. A total of 450 male broiler chickens was distributed into a completely randomized design with six treatments and three replications. Treatments consisted of control diet (CD; CD + coccidiosis vaccine; CD + antibiotic performance enhancers and anticoccidial (APE/AC; CD + glutamine and glutamic acid (Gln/Glu; CD + phytogenic additives (PA; CD + Gln/Glu + PA. Birds on treatment CD + vaccine were vaccinated via drinking water at three days of age against coccidiosis. At 16 days of age all birds of all treatments were inoculated orally and individually with 500,000 oocysts of Eimeria acervulina. There was no treatment effect on lesion score in the intestinal epithelium of birds. The smaller number of excreted oocysts was observed in groups of birds fed diets containing APE/AC and PA. Were observed better results of villus height and crypt depth for duodenum and ileum of birds of treatments containing Gln/Glu at 7 days of age, and Gln/Glu and PA at 21 days of age. Higher percentage of cortical area from bursa follicles was observed in birds fed diets supplemented with Gln/Glu and PA at 7, 14 and 21 days of age. Increased turnover of intestinal mucosa was observed in treatments containing Gln/Glu, indicating acceleration in development and regeneration of damaged tissue. Glutamine plus glutamic acid and phytogenic additives can provide improvements to structure, and thus to intestinal function, as well as to better immune response against the infectious challenges. Phytogenic additives can be used for coccidiosis control of broiler chickens where the use of antibiotic performance enhancers and anticoccidials is prohibited.

    Full Text Available Bursa is one of the cities with high disaster risk and a quality housing problem in Turkey. Urban transformation activities are carried out in order to improve quality of life and create safe living spaces for sustainable urban development. Quality housing production does not signify merely a need to be satisfied quantitatively. Housing and its environment, where physical and social needs of the users are satisfied, should be designed considering local conditions and in a way that they will be suitable for users’ life styles and cultural habits. In this study, the selected study area comprises neighborhoods which are under disaster risk, have been determined as urban transformation areas, and have residents with similar socioeconomic characteristics. With the purpose of improving user satisfaction, this study investigates users’ experience with physical, social, and cultural features of housing and its environment, which identify the quality of housing, and their preferences of new housing units to be produced. Nonprobability sampling method was selected for the field study, and a survey study was conducted. SPSS 17.0 (Statistical Package for Social Sciences was employed for data entry. In order to generate data for quality housing production, relationships between variables were analyzed with Pearson chi-square test.

    The sugarcane borer Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) is an important pest in Brazilian sugarcane crops. Currently, biological control is the most frequently used method for controlling D saccharalis. However, in several locations, the parasitoid Cotesia flavipes (Cameron) (Hymenoptera: Braconidae) has not been effective for controlling this pest, and it has been recorded infestation intensity above 25%. In this context, the Sterile Insect Technique could be an additional control method in Integrated Pest Management, because it is compatible with other control methods. The use of insecticides that interferes in hormone homeostasis involved in the ecdyse's process with exogenous hormone sources or synthetic analogues (agonists or antagonists) can result in the interruption of the reproductive process or abnormal development of the insect?s embryo. Then, the objective of this study was to evaluate the insecticides that regulates the insect growth on the D. saccharalis reproduction. The insecticides tested were: chlorfluazuron (1,0 and 1,5 g a.i./L), diflubenzuron (3,75; 5,0 and 7,5 g a.i./L), flufenoxuron (1,0 g a.i./L), lufenuron (0,75; 1,0 and 2,0 g a.i./L), novaluron (0,5 and 1,0 g a.i./L) pyriproxyfen (1,0; 1,5; 1,8 and 2,0 g a.i./L) and teflubenzuron (1,5; 3,0 and 6,0 g a.i./L). Each insecticide was provided to 1-day moths on soaked cotton with a sugar solution at 10% as a bait. All treatments, except to of the lowest concentration of lufenuron (0,75 g a.i./L) decreased the egg production in relation to the control. Flufenoxuron (1,00 g g a.i./L) and chlorfluazuron (1,50 g a.i./L) decreased the lifespan of both sexes treated by ingestion. Lufenuron (2,0 g a.i./L), novaluron (1,0 g a.i./L) and teflubenzuron (3,0 g a.i./L) decreased the male's lifespan. The most effective treatments for sterilization were pyriproxyfen (1,8 g a.i./L and 2,0 g a.i./L) and lufenuron (2,0 g a.i./L), witch showed efficiencies greater or close to

    Although traumatic lacerations of the olecranon (OB) and praepatellar bursae (PB) are common entities often associated with complications, no study could be found on this injury. The aim of this study was to survey the current treatment concepts for acute traumatic laceration of the OB and PB in Germany, Austria and Switzerland. An international online survey was conducted among orthopaedic and trauma surgeons in Germany (TraumaNetwork DGU), Austria (Austrian Society of Trauma (ÖGU) and Orthopaedic (ÖGO) Surgeons) and Switzerland (Swiss Orthopaedic Surgeons and Swiss Society of Infectious Disease (CH)) (n=1967). The survey comprised of five demographical questions, the current treatment concepts were evaluated using a case study. The overall-response-rate was 16% (12-46%). 88% of the responding physicians were male, aged 47.5 ± 10.2 years with a mean working experience of 20.1 ± 10.6 years. 54% of the surveyed physicians were either senior or chief physicians. Treatment concepts varied significantly between DGU and ÖGO/CH (p=0.02/p=0.006), no significant differences could be found between DGU and ÖGU. Generally, German and Austrian trauma surgeons favoured bursectomy (86.7%/90.9%) and immobilisation (68.3%/77.3%). Austrian orthopaedic surgeons performed fewer bursectomies (69.3%) but had the highest proportion for administering antibiotics (73.9%). Less than 50% of Swiss physicians indicated bursectomy as a treatment option. Overall, this survey revealed a significant heterogeneity in treatment approaches in Central Europe. Further evidence is needed to identify the best treatment concepts for traumatic lacerations of the OB and PB. Copyright © 2012 Elsevier Ltd. All rights reserved.

    The subacromial bursa is recognized as a site associated with the shoulder pain caused by rotator cuff disease in the middle-aged and elderly. Substance P is contained in primary afferent nerves, and its quantity increases during chronic pain. The amount of substance P in the subacromial bursa of patients with rotator cuff disease was examined. Radioimmunoassay and immunohistochemistry were employed to quantify and localize substance P. The preoperative pain level was measured with a visual analogue scale with 0 as no pain, 5 as moderate, and 10 as severe. Thirty-seven patients that had undergone operation were divided into two groups: one composed of 19 patients with subacromial bursitis and a partial-thickness tear of the rotator cuff (nonperforated cuff) and the other composed of 18 patients with a full-thickness tear (perforated cuff). Subacromial bursae obtained from seven fresh cadavers with no shoulder pain before death were used as controls. The visual analogue scale showed significantly greater pain in the group with the nonperforated rotator cuff than in the group with the perforated cuff. Consistent with these results, the amount of substance P in the subacromial bursa was significantly greater in the former group than in the latter. Nerve fibers immunoreactive to substance P were localized around the vessels, with a larger number of fibers in the group with the nonperforated rotator cuff. Therefore, an increased amount of substance P in the subacromial bursa appears to correlate with the pain caused by rotator cuff disease.

    Palmar foot pain is frequently treated by steroid injections into the distal interphalangeal joint (DIPJ) in the anticipation that the steroid will diffuse to the navicular bursa and palmar foot structures. The object of this study was to determine if triamcinolone acetonide (TA) would in fact be able to locally diffuse from the DIPJ into the navicular bursa in horses affected by palmar foot pain. Both forelimb DIPJs (nine horses) were injected with 10 mg of TA. Navicular bursa fluid samples, both forelimb and one hind limb (systemic control), were analysed for TA with high-performance liquid chromatography/tandem mass spectrometry (HPLC-MS/MS) six hours later. Foot radiographs were graded (0-4) on severity of changes. Forelimb navicular bursa TA concentrations (mean±sd log(10), 3.20±0.56) were significantly higher than systemic control concentrations (mean±sd log(10), 1.89±0.3) (P2 were four times as likely to have TA log(10) concentrations less than 3.2 (158.49 ng/ml). TA locally diffused from the DIPJ into the navicular bursa in horses affected by palmar foot pain; TA concentrations decreased as radiographic severity increased.

    Subacromial bursitis (SAB) is the major source of pain in rotator cuff disease. Although multiple investigations have provided support for the role of inflammatory cytokines in SAB, few have focussed on the use these cytokines in the treatment of SAB. The aim of the present study was to observe the therapeutic efficacy of lentivirus‑mediated RNA interference (RNAi) on carrageenan‑induced SAB by injecting lentivirus‑tumor necrosis factor (TNF)‑α‑RNAi expressing TNF‑α small interfering (si)RNA. Using screened siRNA segments, an siRNA was designed. A lentivirus vector expressing siRNA was established and packed as lentivirus particles. A lentivirus that expressed the negative sequence was used as a lentivirus‑negative control (NC). The carrageenan‑induced SAB model was established in 32 male Sprague‑Dawley rats. The modeled rats were randomly assigned to four groups: Lentivirus‑RNAi treatment group, lentivirus‑NC group, SAB group and phosphate‑buffered saline (PBS) blank control group. The lentivirus was injected (1x10(7) transducing units) into the subacromial bursa of the rats in the lentivirus‑RNAi group and lentivirus‑NC group, whereas 100 µl PBS was injected at the same site in the SAB group and the PBS blank control group. At 5 weeks following injection, the animals were sacrificed and venous blood was obtained. The effect of TNF‑α interference and the expression of inflammatory cytokines were determined by reverse transcription‑quantitative polymerase chain reaction, western blotting, hematoxylin and eosin staining, Van Gieson's staining and immunofluorescence. The expression of TNF‑α was decreased in the lentivirus‑TNF‑α‑RNAi group compared with that in the SAB group. Morphological observations revealed that the number of inflammatory cells were reduced and damage to tendon fibers was attenuated in this group, suggesting that the downregulation of the protein expression levels of TNF‑α‑associated nuclear

    Sparganosis is a rare parasitic infection caused by the plerocercoid tapeworm larva of the genus Spirometra. We report the case of a 67-year-old man with a mass over the anteromedial surface of the proximal extremity of the tibia. We surgically excised a bursa containing Spirometra larvae. Sparganosis is a rare parasitic infection. We found no cases of lower extremity sparganosis combined with bursitis reported in the literature. Sparganosis should be considered in the differential diagnosis of soft tissue tumors, especially among patients who frequently have consumed mountain water or raw snakes or frogs.

    Rotator cuff injuries are a common clinical problem either as a result of overuse or aging. Biological approaches to tendon repair that involve use of scaffolding materials or cell-based approaches are currently being investigated. The cell-based approaches are focused on applying multipotent mesenchymal stem cells (MSCs) mostly harvested from bone marrow. In the present study, we focused on characterizing cells harvested from tissues associated with rotator cuff tendons based on an assumption that these cells would be more appropriate for tendon repair. We isolated MSCs from bursa tissue associated with rotator cuff tendons and characterized them for multilineage differentiation in vitro and in vivo. Human bursa was obtained from patients undergoing rotator cuff surgery and cells within were isolated using collagenase and dispase digestion. The cells isolated from the tissues were characterized for osteoblastic, adipogenic, chondrogenic, and tenogenic differentiation in vitro and in vivo. The results showed that the cells isolated from bursa tissue exhibited MSCs characteristics as evidenced by the expression of putative cell surface markers attributed to MSCs. The cells exhibited high proliferative capacity and differentiated toward cells of mesenchymal lineages with high efficiency. Bursa-derived cells expressed markers of tenocytes when treated with bone morphogenetic protein-12 (BMP-12) and assumed aligned morphology in culture. Bursa cells pretreated with BMP-12 and seeded in ceramic scaffolds formed extensive bone, as well as tendon-like tissue in vivo. Bone formation was demonstrated by histological analysis and immunofluorescence for DMP-1 in tissue sections made from the scaffolds seeded with the cells. Tendon-like tissue formed in vivo consisted of parallel collagen fibres typical of tendon tissues. Bursa-derived cells also formed a fibrocartilagenous tissue in the ceramic scaffolds.

    Lipoma arborescens (LA) is a rare benign lesion of unknown etiology. It is characterized histologically by villous proliferation of the synovial membrane and diffuse replacement of the subsynovial tissue by mature fat cells. This condition affects the knee joint most commonly. Cases involving other locations including glenohumeral joint,[1] hip,[2] elbow,[3] hand[4] and ankle[5] have been rarely described. Involvement of the subdeltoid bursa has also been reported, but to date no case has described LA with osseous/chondroid differentiation of this bursa. Another significant finding in our case was the coexistence of LA with intermuscular lipoma, SLAP lesion and labral cyst.

    Large areas of land are disturbed in sensitive bio-diverse mountain environments by Skiruns. Restoration of vegetation on such disturbed mountain sites may be hampered by soil degradation but the severity and nature of the constraints is not well understood. This study was designed to compare the water holding and nutritional status of soil in three Ski runs which had different construction dates and disturbance levels, and the adjacent undisturbed site in the Abies bommuelleriana forest community in the sub-alpine belt of Uludag Mountain (Bithynian Olympus). The values of soil parameters were depressed in proportion to the disturbance level. Water holding capacity (WHC), total nitrogen (N), organic carbon (C) and calcium (Ca2+), magnesium (Mg2+) and potassium (K+) contents (mg kg(-1) dry weight) of soils in the Ski run which had the highest disturbance level were lower than that of the undisturbed adjacent sites. However the results indicated that the soil parameters were less degraded when secondary vegetation was growing on the disturbed areas.

    Injection of the navicular bursa is commonly performed from the palmar aspect of the limb, which results in penetration of the deep digital flexor tendon (DDFT). To report a radiographic guided injection from the lateral aspect of the limb that avoids puncture of the DDFT and to assess synovial and soft tissue penetration by the needle. Prospective clinical and cadaveric study. Prospective analysis of cadaver limbs and clinical cases in which the navicular bursa was injected from the lateral aspect. Cadaver limbs were placed in a stand to simulate weight bearing and injection was performed in limbs without synovial distension or with distension of either the distal interphalangeal (DIP) joint, digital flexor tendon sheath (DFTS) or navicular bursa. In cadaver and clinical limbs, contrast was injected and the needle position assessed with radiographs. Cadaver (but not clinical) limbs were also examined using magnetic resonance imaging with the needle in situ. Successful navicular bursal injection was achieved in all limbs (n = 71). Relative risk of DIP joint puncture was 19 times higher (95% confidence interval 1.3-285.4, Pbursae from clinical cases. The lateral injection technique for the navicular bursa avoids penetration of the DDFT, although risk of synovial penetration must be considered when there is potential DIP joint or DFTS infection. © 2015 EVJ Ltd.

    2014-12-01

    Earthquakes are among the most destructive natural disasters in Turkey and it is important to assess seismicity in different regions with the use of seismic networks. Bursa is located in Marmara Region, Northwestern Turkey and to the south of the very active North Anatolian Fault Zone. With around three million inhabitants and key industrial facilities of the country, Bursa is the fourth largest city in Turkey. Since most of the focus is on North Anatolian Fault zone, despite its significant seismicity, Bursa area has not been investigated extensively until recently. For reliable seismic hazard estimations and seismic design of structures, assessment of potential ground motions in this region is essential using both recorded and simulated data. In this study, we employ stochastic finite-fault simulation with dynamic corner frequency approach to model previous events as well to assess potential earthquakes in Bursa. To ensure simulations with reliable synthetic ground motion outputs, the input parameters must be carefully derived from regional data. In this study, using strong motion data collected at 33 stations in the region, site-specific parameters such as near-surface high frequency attenuation parameter and amplifications are obtained. Similarly, source and path parameters are adopted from previous studies that as well employ regional data. Initially, major previous events in the region are verified by comparing the records with the corresponding synthetics. Then simulations of scenario events in the region are performed. We present the results in terms of spatial distribution of peak ground motion parameters and time histories at selected locations.

    2017-12-01

    Full Text Available The efficacy of Diatomaceous earth (DAE in reducing the detrimental effects of aflatoxin (AF in broiler diet was evaluated. DAE was supplemented 2000 mg/kg of feed along with 0.5 and 1 ppm of AF in feed. A total of 240 healthy day old broiler chicks were divided into 6 groups comprising of control and treatment groups. Feeding of AF resulted in reduction in size of the thymus, spleen and bursa of Fabricius. In addition, petechial haemorrhages were observed on the surface of the thymus. Histopathology revealed varying degree of lymphocytolysis and depletion of lymphoid cells in thymus, spleen and bursa of Fabricius. In addition, the ceacal tonsils also revealed a mild to moderate degree of lymphoid depletion. The supplementation of DAE to aflatoxin-mixed feed revealed significant improvement characterised by decreased severity of lesions in lymphoid organs. The macroscopic and microscopic changes in the birds fed DAE in combination with AF included those that were observed in AF- alone fed birds, but of reduced magnitude and severity. The study concluded that 2% DAE in feed can be effectively used to reduce the the histotoxic effects of aflatoxin on lymphoid organs in broiler chicken.

    The effect of dietary thyme-oil extract (TOE) supplementation on immune functions of broilers were assessed by feeding graded levels (50, 100, 200, or 400 ppm) of TOE to male broiler chicks during a 42-d feeding trial compared with negative- or positive-control diets. Dietary control treatments included a negative-control diet with no feed-additive supplementation and 2 positive-control groups supplemented with either virginiamycin or zinc bacitracin. In total, 300 1-day-old Ross × Ross male broilers were randomly assigned to 6 dietary treatments that consisted of 5 replicates of 10 birds each. On d 21 and 42, 2 birds from each replicate were killed by cervical cutting to measure the relative weights of spleen and bursa of Fabricius. At 25 d of age, chicks were injected with 0.5 mL of 10% SRBC suspension. Broilers fed with 200 ppm of TOE had heavier weights of bursa of Fabricius than those fed other dietary treatments at d 42 of age. Furthermore, dietary inclusion of 100 ppm of TOE resulted in higher (P < 0.05) total immunoglobulin response in primary antibody titer against sheep erythrocytes compared with other dietary treatments. On the other hand, diet modifications had no significant effect on blood leukocyte subpopulations and heterophil-to-lymphocyte ratio. These results suggest that dietary supplementation with TOE, especially at the level of 100 ppm, can improve immunological responses of broiler chicks. © 2015 Poultry Science Association Inc.

    The purpose of the study was to evaluate whether use of a bi-polar radiofrequency (RF) ablation wand would cause excess heating, which may lead to collateral damage to the surrounding tissues during arthroscopic subacromial decompression. Cadaveric studies have shown that high temperatures can potentially be reached when using RF ablation wands in arthroscopic shoulder surgery. Only 1 other published study assesses these temperature rises in the clinical setting. Fifteen patients were recruited to participate in the study. A standard arthroscopic subacromial decompression was performed using continuous flow irrigation, with intermittent use of the RF ablation wand for soft tissue debridement. The temperature of the irrigation fluid within the subacromial bursa and the outflow fluid from the suction port of the wand were measured during the procedure using fiber-optic thermometers. The mean peak temperature recorded in the subacromial bursa was 32.0°C (29.3-43.1°C), with a mean rise from baseline of 9.8°C. The mean peak temperature recorded from the outflow fluid from the wand was 71.6°C (65.6-77.6°C), with a mean rise from baseline of 49.4°C. High temperatures were noted in the outflow fluid from the wand; however, this was not evident in the subacromial bursa itself. Use of room temperature inflow fluid, maintenance of flow through the bursa, and avoidance of prolonged uninterrupted use of the wand all appear to ensure that safe temperatures are maintained in the subacromial bursa not only in the laboratory but also in a clinical setting.

    A first comprehensive textbook on burns treatment was written in 1607 by Fabry of Hilden (Fabricius Hildanus). This monograph describes cause, diagnosis, treatment, and complications of burn injuries. Besides a variety of topical ointments with promising herbal ingredients like onion and camphor, surgical procedures like necrectomies, escharotomies and syndactely treatment are described for the first time ever. Scar management including splinting devices is another interesting topic. Some of the therapeutic procedures are still valid today. Thus this renaissance piece of medical writing belongs to the pedigree of surgery.

    Full Text Available The affixes used during the verb processing in the Turkey Turkish dialects show important phonetic variations. These affixes, which are commonly used in all the Turkey Turkish dialects, differ from one region to another, even from one village to another in the same region, in having varying phonetic characteristics. Of these affixes, those which undergo change most frequently and function as a key to the determination of the ethnic structure of the region in question are the future tense and present continuous tense suffixes. In Bursa local dialects, the final phoneme /r/ of the present continuous tense suffix –(Iyor predominantly was omitted and the neighboring vowel was lengthened. However, we observe that the initial vowel of the future tense suffix –AcAk was omitted and the back vowel /a/ was changed to the front vowel /e/ in the second syllable. We come across some different uses in the person suffixes following these suffixes. In this article, it is aimed to put forth various uses of the affixes in question and other verb processing affixes used in the local dialects of Bursa.

    1987-09-01

    The effect of aflatoxin in poultry is greater on birds fed a low fat diet, but it is not known whether this effect is associated with a lower apparent minimum effective dose (MED), altered slope of the response curve, or both. Aflatoxin at 16 dosages ranging from 0 to 3.797 micrograms/g of feed was fed to six groups of 15 young chickens per treatment ingesting a 2 or 4% fat diet for 3 wk. The weights of the body, liver, bursa of Fabricius, and spleen and the total lipid content of the liver were measured. Mathematical models were fitted to the data and dose-response curves were predicted as continuous functions of aflatoxin concentration. Quadratic polynomials fit body weight and spleen weight whereas plateau-linear models fit liver weight and liver lipid content in both 2 and 4% fat diets. The weight of the bursa of Fabricius was fit equally well by quadratic and linear plateau models. Dietary fat had negligible effects on the apparent MED (micrograms of aflatoxin per gram of feed) for body, liver and spleen weights, which were calculated from the modeling approach to be 1.37 and 1.41, 1.68 and 1.69, and 1.49 and 1.46 on 2 and 4% fat diets, respectively. The apparent MED for liver lipid content was appreciably lower for birds fed the 2% fat diet than those fed the 4% fat diet (.88 and 1.62, respectively). Similarly, the apparent MED for the bursa was 1.48 and 1.74 for birds fed the 2 and 4% fat diets, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

  9. Somatic diversification of the chicken immunoglobulin light-chain gene.

    1990-01-01

    The bursa of Fabricius provides a unique organ for the study of lineage-specific development in a multicellular organism. Unlike mammalian B cells, B cells in the chicken develop in a single wave of differentiation, beginning with the commitment of progenitor cells to the B cell lineage between days 10 and 15 of embryogenesis. By day 18 of embryogenesis, all lymphoid progenitor cells capable of differentiation along the B cell lineage have migrated to the bursa of Fabricius. Following migration to the bursa, these lymphoid progenitors enter exponential growth and begin to populate each of the 10(4) bursal follicles. Between day 18 of embryogenesis and 2-4 weeks of age, B cells undergo a stage of bursal-dependent differentiation. By the end of this period, chickens are able to mount primary immune responses against virtually all antigens. In addition, by this time sufficient numbers of B cells have migrated from the bursa to peripheral lymphoid organs so that the B cell immune system can be maintained even if the bird is bursectomized. Bursectomy of chicks after 4 weeks of age has no long-term effects on the development and maintenance of the B cell immune system in adult birds. Because of the central nature of the surface Ig molecule to B cell development in mammals, the chicken IgL gene locus has been intensively studied during avian B cell development. The chicken IgL locus is a particular interest because it has only one V region capable of rearrangement. Rearrangement of the IgL gene is not dependent on the bursal environment. B cell progenitors rearrange their IgL gene between days 10-15 of embryogenesis, prior to migration to the bursa. IgL gene rearrangement occurs by a deletional mechanism in which a precise joining of the IgL recombination signal sequences leads to a circular episomal element. During this deletion it appears that single nonrandom bases are added to both the V and J coding segments. Subsequent V-J joining occurs at random. Most progenitor B

    Elucidating the basic life-history of endangered species is the first important step in the conservation of such species. This study examined the reproductive ecology and the preimaginal morphology of the endangered ground beetle Elaphrus sugai Nakane (Coleoptera: Carabidae); currently, the Watarase wetland of the central Kanto Plain, Japan is the only confirmed locality of this beetle species. Laboratory rearing of reproductive adults collected in early April revealed that females can lay more than 131 eggs. Eggs were laid in mud, without an egg chamber. Larvae reached adulthood when fed a diet of mealworms, indicating that E. sugai larvae are insect larvae feeders. An earthworm diet, the optimal diet for larvae of a congeneric species (E. punctatus Motschulsky), was lethal to E. sugai larvae. The egg stage was 3-4 days in duration under a 16L8D cycle (22°C). The duration from hatching to adult eclosion was 23-42 days at various temperatures simulating those of the reproductive period. Larval morphology was similar to that of consubgeneric species described previously. The pupa is unusual, in that the setae on the abdominal tergites are long (twice as long as those of the abdominal segment) and have somewhat "coiled" apices. Finally, the current endangered status of E. sugai was compared to that of E. viridis Horn, which has been regarded as the most endangered species of the genus worldwide.

    Full Text Available Climate is the dominant factor determining the distribution and abundance of most insect species. In recent years, the issue of climatic changes caused by human activities and the effects on agriculture has raised concern. General circulation model scenarios were applied to a bioclimatic model of Melanoplus sanguinipes to assess the potential impact of global warming on its distribution and relative abundance. Native to North America and widely distributed, M. sanguinipes is one of the grasshopper species of the continent most responsible for economic damage to grain, oilseed, pulse, and forage crops. Compared to predicted range and distribution under current climate conditions, model results indicated that M. sanguinipes would have increased range and relative abundance under the three general circulation model scenarios in more northern regions of North America. Conversely, model output predicted that the range of this crop pest could contract in regions where climate conditions became limiting.

    To introduce an arthroscopic technique in managing recurrent dislocation of the patella and its clinical results. Sixteen patients with recurrent patellar dislocation were reviewed, including 3 males and 13 females. The average age was 17.6 years old (ranged from 14 to 32 years). The patients suffering from patellar sub-luxation averaged 18.5 months (ranged from 6 to 23 months)before operation. These patients were treated with lateral patellar retinacular release outside the synovial bursa of knee joint and medial patellofemoral ligament reconstruction using the semitendinosus tendon free autograft. The Lyshohm scores before and after operation were used to evaluate outcomes at the final follow-up. All the patients were followed up, and the duration ranged from 6 to 48 months, with an average of 12 months. There was no recurrence. The Q angle decreased from (16.4 ± 3.7)° to (10.1 ± 1.4)°; insall index decreased from 1.37 ± 0.25 to 1.28 ± 0.23; congruence angle decreased from (21.3 ± 2.6)° to (5.86 ± 2.23)°; Lysholm score improved from 76.1 ± 5.2 to 89.8 ± 4.1 at 6 months after operation. Compared with conventional procedure, arthroscopic surgery for recurrent dislocation of the patella achieves excellent outcomes with minimum invasion.

    Full Text Available The current study was conducted to evaluate the pathogenicity and immunosuppressive effects of GM-97 strain of infectious bursal disease virus in commercial broiler chickens. A total of 500 broiler chickens were vaccinated with the virus through oral route at 10 and 17 days of age (102-103 EID50/dose. Chickens were also vaccinated with Newcastle disease virus (Hitchner B1 orally at 14 and 21 days old. Chickens were euthanized (at 12, 14, 16, 20, 23, 26 days of age after measuring body weight. Bursa of Fabricius was examined for any gross lesion, weighed and processed for histological investigations. Bursa to body weight ratio and bursal lesion scoring were made to evaluate pathogenicity of the virus. Blood samples were analyzed for antibody response to ND vaccine virus using HI test. Results showed that the GM-97 strain of IBDV induced mild to moderate depletion of lymphoid cells in the center of bursal follicles and non-significant difference in bursa to body weight ratio amongst vaccinated and unvaccinated chickens. Chickens responded well to ND vaccine by mounting high level of serum NDV specific HI antibody titers. It can be concluded from the present study that GM-97 strain of IBDV has mild pathogenicity but is not immunosuppressive.

    Acute hip pain is a common reason for attendance to hospital. Immediate diagnoses include occult fractures, infectious and non-infectious inflammatory processes such as gout and pseudogout. Calcium pyrophosphate deposition disease (CPDD) is a rheumatological syndrome affecting articular cartilage and/or synovial fluid. It can occur as a clinical presentation (pseudogout) where calcium pyrophosphate dihydrate (CPPD) crystals are deposited within the joint space or radiographically, as chondrocalcinosis (CC), where CPPD crystals are deposited onto articular cartilages. Extraarticular manifestations of CPDD are rare. The authors report a case of CPPD deposition in the trochanteric bursa of a 35-year-old woman presenting as acute hip pain. The patient was treated successfully during arthroscopy with removal of the deposits and excision of the bursa. The patient remains well at 6 month follow-up.

    Full Text Available The different patterns of the caudal bursa of the Heligmonellidae (Nematoda are redefined, taking into account the grouping of rays 2-6 and the sequence of origin of these rays from their common trunk. The type of symmetry of the caudal bursa is also redefined. The following patterns were observed and characterized: the basic patterns: types 2-3, 2-2-1, 1-3-1 and 1-4 and the intermediary patterns: type 2-3 tending to type 2-2-1, type 2-2-1 tending to type 1-3-1, type 1-3-1 tending to type 1-4 and type 2-2-1 tending to type 1-4. An evolutionary interpretation of the patterns is attempted and seems to follow the direction: 2-3 to 2-2-1 to 1-3-1 to 1-4. Seven atypical patterns are described. The caudal bursae were classified based on their symmetry: subsymmetrical, dissymmetrical and asymmetrical. Independently of the type of symmetry, the two latero-ventral lobes may have the same or different patterns. The type of symmetry, the ratio between the two latero-ventral lobes and a characteristic pattern were utilized to characterize the caudal bursae at the level of the genus and the subfamily. The combination of the right/left ratio and the type of symmetry gives heterogeneous results, with no real association between these characters. The most conspicuous asymmetries and dissymmetries were found among the Nippostrongylinae. The most frequent pattern in the Heligmonellidae is the basic type 2-2-1; types 1-3-1 and 1-4 are less frequent but are characteristic of several genera; type 1-4 is absent from the Heligmonellinae. Whatever the pattern, in the Heligmonellidae rays 4 and 5 are the last to diverge from the common trunk of rays 2-6.

    Full Text Available The glucosinolate rich hot and cold hexane extracts of Brassica juncea had a negative effect on the development of Spodoptera litura larvae when they were fed on different concentrations of the extracts. Both larval growth index and pupal growth index declined with treatment. However the hot extract with 3-butenyl isothiocyanate as the predominant compound had a more deleterious effect as at 3125ppm the larvae were unable to complete their development. The nutritional indices too were more adversely affected with hot extract as compared to cold extract. The RGR, RCR, ECI and ECD declined significantly with increase in concentration of the hot hexane extract. The activity of antioxidant enzymes, SOD and catalase decreased while that of phosphatases, GSTs, phenol oxidases increased during the initial treatment duration but decreased on prolonged treatment of the larvae with LC50 concentration of hot extract. A similar trend was observed for glutathione and lipid peroxides but a decrease in ascorbate content was observed as compared to control. The findings reveal a toxic effect of 3-butenylisothiocyanate rich hot hexane extract of B. juncea on S. litura larvae.

    Considering that crimes against animals such as illegal killing and cruelty have been alarmingly increasing and since burning is one of the common ways for disposing cadavers, ability to estimate minimum postmortem interval (PMI) using entomological data merits consideration. Chrysomya megacephala and Chrysomya rufifacies are common necrophagous species recovered from cadavers in many countries including Malaysia. Specific studies focusing on the oviposition and developmental patterns of both species on cadavers manifesting different levels of burn as described by the Crow-Glassman Scale (CGS) remain scarce. In four replicates, rabbit carcasses were burned to CGS levels #1, #2 and #3 by varying the amount of petrol used and duration of burning. Oviposition by C. megacephala and C. rufifacies was delayed by one day in the case of carcasses burned to the CGS level #3 (p0.05) in the duration of development were found between control and burned carcasses. These findings deserve consideration while estimating minimum PMI since burning as a mean for disposing animal and human cadavers is gaining popularity. Copyright © 2016 Elsevier Ireland Ltd.

    The fumigant toxicity of Xylopia parviflora (A. Rich.) Benth (Annonaceae) root bark's essential oil (EO) against cowpea seed bruchid, Callosobruchus maculatus, was investigated in the laboratory. Dose had significant (P < 0.0001) effect on mortality at 6 hours after treatment (HAT) at a concentration of 6.25 μL/mL air which exerted 81.70% mortality, while there was no mortality in all other lower doses. At 12 HAT, 75.05% and 90.00% mortality were observed at doses of 3.15 and 6.25 μL/mL air, respectively. It was significantly (P < 0.05) higher than the mortality (50.58%) observed when 0.78 μL/mL air was applied. The lethal time for 50% of assayed adults (LT50) obtained when the bruchid was exposed to X. parviflora EO at a dose of 6.25 μL/mL air (2.71 h) was significantly lower than LT50 obtained at exposure of bruchid to other lower doses of 0.78-3.15 μL/mL air.

  4. RNAi-mediated knockdown of catalase causes cell cycle arrest in SL-1 cells and results in low survival rate of Spodoptera litura (Fabricius.

    Full Text Available Deregulated reactive oxygen species (ROS production can lead to the disruption of structural and functional integrity of cells as a consequence of reactive interaction between ROS and various biological components. Catalase (CAT is a common enzyme existing in nearly all organisms exposed to oxygen, which decomposes harmful hydrogen peroxide, into water and oxygen. In this study, the full length sequence that encodes CAT-like protein from Spodoptera litura named siltCAT (GenBank accession number: JQ_663444 was cloned and characterized. Amino acid sequence alignment showed siltCAT shared relatively high conservation with other insect, especially the conserved residues which defined heme and NADPH orientation. Expression pattern analysis showed that siltCAT mRNA was mainly expressed in the fat body, midgut, cuticle and malpighian tube, and as well as over last instar larvae, pupa and adult stages. RNA interference was used to silence CAT gene in SL-1 cells and the fourth-instar stage of S. litura larvae respectively. Our results provided evidence that CAT knockdown induced ROS generation, cell cycle arrest and apoptosis in SL-1 cells. It also confirmed the decrease in survival rate because of increased ROS production in experimental groups injected with double-stranded RNA of CAT (dsCAT. This study implied that ROS scavenging by CAT is important for S. litura survival.

    The pathophysiology of subacromial impingement syndrome is poorly understood. We investigated the expression of inflammatory cytokines, metalloproteases, and the cyclooxygenases in the subacromial bursa in control patients and in patients with rotator cuff tear. Basic science evaluation. Eighteen patients undergoing shoulder surgery had a subacromial bursa biopsy examination. Patients were divided into 2 groups. Group I (study group) had 10 patients with a full-thickness rotator cuff tear (RCT). Group II (control group) had 8 patients. Seven of 8 underwent shoulder arthroscopy with anterior capsular reconstruction for instability; 1 of 8 underwent open reduction internal fixation for acute proximal humerus fracture. None of the patients in group II had any history of symptoms or signs consistent with subacromial impingement. H&E and immunohistochemical antibody (MMP-1, MMP-9, IL-1, IL-6, TNF-alpha, COX-1, and COX-2) stained specimens were examined by 2 blinded observers using a histologic scale (grade 0 = no staining to grade 4 = intense staining). Histologic evidence of inflammation was present in all patients with RCT (group I). No or mild inflammation was noted in group II. The average staining grade for inflammatory cytokines (IL-1, IL-6, TNF-alpha) and proteinases (MMP-1 and MMP-9) was significantly more pronounced in the RCT group (P bursa of patients with rotator cuff tear. These findings support the role of nonsteroidal anti-inflammatory drugs and corticosteroids in RCT treatment, and emphasize the importance of subacromial bursectomy to reduce inflammation in RCT surgery.

    Chemokines produced by synoviocytes of the subacromial bursa are up-regulated in subacromial bursitis and rotator cuff disease. We hypothesized that SDF-1α production in bursal synoviocytes may be induced by local cytokines such as interleukin IL-1β and IL-6. Subacromial bursa specimens were obtained from patients undergoing shoulder surgery. Bursal specimens were stained with anti-human antibodies to IL-1, IL-6, and SDF-1α by immunohistochemistry and compared to normal and rheumatoid controls. Bursal cells were also isolated from specimens and cultured. Early passaged cells were then treated with cytokines (IL-1β and IL-6) and SDF-1α expression was measured by ELISA and RT-PCR. SDF-1α, IL-1β, and IL-6 were expressed at high levels in bursitis specimens from human subacromial bursa compared to normal controls. In cultured bursal synoviocytes, there was a dose-dependent increase in SDF-1α production in the supernatants of cells treated with IL-1β. SDF-1α mRNA expression was also increased in bursal cells treated with IL-1β. IL-6 caused a minimal but not statistically significant increase in SDF-1α expression. SDF-1α, IL-1β, and IL-6 are expressed in the inflamed human subacromial bursal tissues in patients with subacromial bursitis. In cultured bursal synoviocytes, SDF-1α gene expression and protein production are stimulated by IL-1β. IL-1β produced by bursal syvoviocytes and inflammatory cells in the human subacromial bursa is an important signal in the inflammatory response that occurs in subacromial bursitis and rotator cuff disease.

    Partial sequences of the mitochondrial COI gene of forty eight European and two Turkish population samples of Myzus cerasi from different winter hosts (Prunus spp.) were subjected to phylogenetic analyses. The analysed M. cerasi samples emerged as paraphyletic relative to a Myzus borealis sample used as an out-group, and formed two major clades in neighbor joining, maximum parsimony, maximum likelihood and Bayesian inference trees, corresponding to subspecies living specifically on Prunus avium and P. cerasus. Multivariate discriminant analysis (method of canonical variates) was applied to find out if morphological variation of samples correlated with mitochondrial COI and host plant information. Mean scores on the first two canonical variables clustered samples fully in accordance with their COI haplotypes and host plants confirming the existence of two morphologically similar winter host - specific subspecies of M. cerasi in Europe. No single morphological character enabled satisfactory discrimination between apterous viviparous females of the two subspecies. A three-character linear discriminant function enabled 92.37% correct identification of apterous viviparous females of M. cerasi cerasi (n = 118) and 93.64% of M. cerasi pruniavium (n = 110). A key for the morphological identification of the two subspecies is presented and their taxonomic status is discussed.

    Full Text Available Neuropeptides play essential roles in a variety of physiological responses that contribute to the development and reproduction of insects. Both the diapause hormone (DH and pheromone biosynthesis activating neuropeptide (PBAN belong to the PBAN/pyrokinin neuropeptide family, which has a conserved pentapeptide motif FXPRL at the C-terminus. We identified the full-length cDNA encoding DH-PBAN in Maruca vitrata, a major lepidopteran pest of leguminous crops. The open reading frame of Marvi-DH-PBAN is 591 bp in length, encoding 197 amino acids, from which five putative neuropeptides [DH, PBAN, α-subesophageal ganglion neuropeptide (SGNP, β-SGNP and γ-SGNP] are derived. Marvi-DH-PBAN was highly similar (83% to DH-PBAN of Omphisa fuscidentalis (Lepidoptera: Crambidae, but possesses a unique C-terminal FNPRL motif, where asparagine has replaced a serine residue present in other lepidopteran PBAN peptides. The genomic DNA sequence of Marvi-DH-PBAN is 6,231 bp in size and is composed of six exons. Phylogenetic analysis has revealed that the Marvi-DH-PBAN protein sequence is closest to its homolog in Crambidae, but distant from Diptera, Coleoptera and Hymenoptera DH-PBAN, which agrees with the current taxonomy. DH-PBAN transcripts were present in the head and thoracic complex, but absent in the abdomen of M. vitrata. Real-time quantitative PCR assays have demonstrated a relatively higher expression of Marvi-DH-PBAN mRNA in the latter half of the pupal stages and in adults. These findings represent a significant step forward in our understanding of the DH-PBAN gene architecture and phylogeny, and raise the possibility of using Marvi-DH-PBAN to manage M. vitrata populations through molecular techniques.

    Full Text Available Chemical analysis of turmeric (Curcuma longa extracts using TLC/densitometry, showed an extract contain 21.57%w/w of three important curcuminoids: curcumin, desmethoxycurcumin and bisdesmethoxycurcumin. GC and MS were used to analyze volatile oils. Aromatic turmerone, α-turmerone and zingiberene were also obtained. Qualitative and quantitative analyses alcoholic extract of Andrographis paniculata using TLC, revealed that the extracts contain three important compounds in total lactone of 30.49% w/w. There are andrographolide,14-deoxy-11-12-didehydroandrographolide and neoandrographolide. TLC-chromatogram of Clinacanthus nutans extract after reacted with anisaldehyde/sulfuric acid showed a 9 key compounds, while preliminary neutralization test of the compounds revealed that there were active compounds against HSV-1 virus. In vitro efficacy test revealed that Curcuma longa and Andrographis paniculata extracts at 250 and 1,500 mg/L could eradicate 15 isolates of Vibrio spp. which were isolated from infected shrimps. Effects of medicinal plant extracts incorporated into the diet on shrimp immune responses were investigated. Shrimp fed diet containing Clinacanthus nutans extract at 20 mg/kg of diet had good growth, FCR and immune responses. The shrimp that were fed diet containing Curcuma longa extracts at 25 mg/kg of diet for 7-14 days showed high resistance to Vibrio harveyi. Likewise, the shrimp fed Andrographis paniculata extract at 25 mg/ kg of diet for 14 days had a higher resistance to WSSV. Incorporating the medicinal extracts at higher levels resulted in reduction in diet palatability which consequently had an effect on a decrease in growth, immune responses and resistance to bacterial and WSSV infection.

    Full Text Available Two feeding trial were conducted to determine the effects of various sources of carotenoid on growth performance, disease resistance, blood parameters, stress tolerance and pigmentation in juvenile black tiger shrimp (Penaeus monodon. Trial I was performed in small shrimp (1 g average body weight. The shrimp were fed with control diet without carotenoid (diet 1 while diets 2 to 6 contained 50 mg/kg astaxanthin (Lucanthin Pink®, 125 mg/kg β-carotene (Lucarotin®, 200 mg/kg β-carotene (Lucarotin®, 125 mg/kg Betatene® extracted from Dunaliella and 3% dried Spirulina respectively. There was an improvement in color in all groups of shrimp fed caroteniod supplemented diets, but no significant differences in weight gain or survival among the shrimps fed each test diet (p>0.05. Resistance to white spot syndrome virus (WSSV infection and stress tolerance (salinity stress, were not significantly different among treatments. Trial II was performed in juvenile shrimp (10 g average body weight fed test diets containing 100 ppm astaxanthin (Lucanthin pink®, 125 mg/kg β-carotene (Lucarotin®, 250 mg/kg β-carotene (Lucarotin®, 250 mg/kg Betatene® and 3% dried Spirulina compared with those fed control diet without carotenoid. At the end of 6 weeks feeding period, shrimp fed control diet as well as astaxanthin and dried Spirulina supplemented diets had higher levels of total hemocyte counts than those of all β-carotene supplemented diets feeding group. However, phenoloxidase activity and clearance of pathogenic vibrio from the hemolymphwere not significantly different among the treatments (p>0.05. Astaxanthin levels were highest in the shrimp fed all carotenoid-supplemented diets. In conclusion, a natural carotenoid i.e. dried Spirulina and carotenoid extracted from Dunaliella which have a lower production cost than analytical carotenoid showed beneficial effects on shrimp feed supplement.

    We examined the morphology of setae and microtrichia in Aquarius paludum during larval development using a scanning electron microscope. We then conducted immersion experiments with larvae and adults in oxygenated and deoxygenated water. The adult water strider body is covered by a pilose double layer consisting of upper long setae (30-80 microm) and lower filiform microtrichia (5-9 microm). Only setae are present on the legs. Microtrichia on the larval body are very short: 0.5-0.6 microm in first and second instars, and 0.8-1.7 microm in third to fifth instars. Larval body setae are approximately as long as those of adults (25-50 microm), but are much less dense at 1,800-5,750 setae per mm(2) versus 15,000-20,000 setae per mm(2) in adults. The density of setae on the legs remains relatively constant throughout development (larvae: 15,000-20,000 setae per mm(2); adults: 20,000-26,000 setae per mm(2)). Immersion experiments demonstrated that young instars may use cuticular respiration. First- and second-instar larvae survived underwater for several hours without a visible air supply, although they did not survive in deoxygenated water. We posit that the short body microtrichia have a waterproofing function in larvae, whereas they create a compressible air bubble in adults. In adults, waterproofing is accomplished by the setae. The density and length of setae on the legs of larvae was nearly the same as that on the body and legs of adults and is presumably optimized for waterproofing. Thus, a change in morphometrical parameters can result in a large functional change in the same structure. We discuss this interpretation in both ecological and physiological contexts. 2008 Wiley-Liss, Inc

    Full Text Available AIM: Obesity is one of the risk factors of metabolic syndrome (MetS and its prevalence is rapidly increasing in Turkey. The purpose of this study was to assess the prevalence of MetS and obesity among women aged 20 years and older. METHOD: This is a cross- sectional study, undergone in a primary health care setting in Bursa /Turkey in the year 2008. A total of 807 women were included in the study. Body weight, height, waist circumference, blood pressure, total and HDL cholesterol, fasting plasma glucose and triglyceride levels were measured. Metabolic Syndrome definition was made according to the International Diabetes Federation (IDF criteria. RESULTS: The mean age was 42.713.2 years, 96.4% were married, 50.7% had education of less than 8 years, 93.7% were housewives and 85.3% had a monthly family income of $650 or less. The prevalence of MetS and abdominal obesity were 17.5 % and 87.7% respectively. Those with diabetes mellitus and elevated plasma lipids had increased risk of developing MetS 11.3 and 4.5 times more than those without these situations respectively. The risk of MetS increases with age and increasing BMI. CONCLUSION: Obesity is an alarming risk factor for the development of MetS in our study group. [TAF Prev Med Bull 2011; 10(4.000: 421-432

    Full Text Available The first half of the twentieth century saw the rise of a new type of novel that straddled the divide between popular entertainment and legitimate culture by combining ‘high’ and ‘low’ literary forms and catering en masse for the tastes of an expanding middleclass reading public. In this article we want to explore the ways in which the novels La Madone des sleepings (1925 by the bestselling French novelist Maurice Dekobra and Venetiaansch avontuur [Venetian adventure] (1931 by the Dutch author Johan Fabricius fit into this broad category of the middlebrow novel and how their use of adventure as a structural devise might complicate the common view of the middlebrow novel as a form of domestic realism.

    Full Text Available Electrical and electronical equipment that gradually take more place in our daily life, spend their service life in short times and become an e-waste problem to be solved.  Because of the hazardous components they contain, e-waste can cause environmental and human health threats if they are not properly managed. If they are managed properly, they can be a valuable raw material source, since they contain valuable metals such as copper, silver, gold, palladium and recyclable components such as plastics and metals. According to a research conducted in 2014, the global e-waste amount accounts to a source worth 52 billion $; however, only 16% of this source has been properly recycled. It is important to know the potential e-waste amount and the behaviors of people in the production of e-waste to realize a proper e-waste management in our country. The amount and property of electrical and electronic equipment and e-waste generation potential per person in Bursa was investigated in this study. A questionnaire was prepared and applied to a group of people including 31 families (100 person. The questions were to investigate the behaviors in the use, replacement, and management of electrical and electronical equipment. The findings showed that usage of lamps (fluorescent and others were higher than the other equipment, and usage of mobile phones were found to be highest in terms of devices. It was also found that when the mobiles become e-waste since the owners do not want to use them, they are not just thrown away and kept at homes instead. E-waste generation potential of a person from the families investigated was estimated to be 8.14 kg/year.

    To report patient outcomes up to 1 month after fluoroscopy-guided iliopsoas bursa injection for suspected iliopsoas tendinopathy. Thirty-nine consecutive patients (mean age 45 years; range 15-77) who underwent fluoroscopy-guided therapeutic iliopsoas bursa injection using an anterolateral approach and who returned an outcomes questionnaire were prospectively included. The Patients' Global Impression of Change (PGIC) scale was recorded 1 day, 1 week, and 1 month after the injection (primary outcome measure). Patients' subjective pain level data were collected prior to the injection (baseline) using a numeric rating scale (NRS; 0 = no pain; 10 = maximum pain). NRS scores were completed 15 min, 1 day, 1 week, and 1 month post-injection and compared to baseline. Forty-nine per cent of patients reported clinically relevant 'improvement' (PGIC) 1 month post-injection. Mean NRS score prior to injection was 5.9 ± 2.1. Mean NRS scores after 15 min (3.6 ± 2.7), 1 day (4.4 ± 2.7), 1 week (3.4 ± 1.9), and 1 month (3.5 ± 2.5) were statistically significantly lower (p ≤ 0.001) compared to baseline. Reduction of NRS ≥50 % after 15 min was achieved in 49 % (56 % of those unimproved at 1 month). Fluoroscopy-guided iliopsoas bursa injection leads to a relevant 'improvement' at 1 month or significant pain reduction after 15 min in most patients.

    Full Text Available Blowflies use discrete, ephemeral breeding sites for larval nutrition. After exhaustion of the food supply, the larvae disperse in search of sites to pupate or to seek other sources of food in a process known as post-feeding larval dispersal. In this study, some of the most important aspects of this process were investigated in larvae of the blowflies Chrysomya megacephala exposed to a variety of light: dark (LD cycles (0:0 h, 12:12 h and 24:0 h and incubated in tubes covered with vermiculite. For each pupa, the body weight and depth of burrowing were determined. Statistical tests were used to examine the relationship of depth of burrowing and body weight to photoperiod at which burrowing occurred. The study of burial behavior in post-feeding larval dispersing can be useful for estimating the postmortem interval (PMI of human corpses in forensic medicine.Moscas-varejeiras usam substratos discretos e efêmeros para nutrição larval.

    Full Text Available The lacewings (Ceraeochrysa cincta are important predators found associated to many pests in several agroecosystems. Eggs of Sitotroga cerealella and Anagasta kuehniella are used traditionally for massal rearing of these predators. Other foods can be used in substitution to the traditional ones, but little is known about the biology of lacewings and other alternative foods. So, this work was carried out to evaluate the effect of different diets on the post-embryonic development of C. cincta in laboratory. After been individualized in glass tubes, each larva was fed with S. cereallella and Diatraea saccharallis. It was evaluated the larvae duration, weight and viability in each instar, the duration, weight and viability of the pupa and pre-pupa stages and the duration of the post-embryonic period. It was adopted a completely randomized design with ten replications per treatment, each consisting of five eggs or larvae of C. cincta. Larvae were weighed 48 hours after hatching and 48 hours after each molt, and pre-pupae and pupae, 48 hours after starting these stages. There was no effect of the kind of food provided on the parameters evaluated. Therefore, D. saccharallis eggs can be used to feed C. cincta.Os crisopídeos são importantes predadores encontrados associados a diversos artrópodes-praga em diversos agroecossistemas.

  13. Efficient antibody diversification by gene conversion in vivo in the absence of selection for V(D)J-encoded determinants.

    Sayegh, C E; Drury, G; Ratcliffe, M J

    1999-11-15

    Antibody diversification in the bursa of Fabricius occurs by gene conversion: pseudogene-derived sequences replace homologous sequences in rearranged immunoglobulin genes. Bursal cells expressing a truncated immunoglobulin mu heavy chain, introduced by retroviral gene transfer, bypass normal requirements for endogenous surface immunoglobulin expression. Immunoglobulin light chain rearrangements in such cells undergo gene conversion under conditions where the products are not selected based on their ability to encode a functional protein. The efficiency with which gene conversion maintains a productive reading frame exceeds 97% under such non-selective conditions. By analysis of donor pseudogene usage we demonstrate that bursal cell development is not driven by a restricted set of antigenic specificities. We further demonstrate that gene conversion can restore a productive reading frame to out-of-frame VJ(L) junctions, providing a rationale for the elimination of cells containing non-productive VJ(L) rearrangements prior to the onset of gene conversion in normal bursal cell development.

    The effect of infectious bursal disease virus (IBDV) on the infections caused by Escherichia coli strains of high (Expt 1) and low (Expt 2) virulence was examined in specific-pathogen-free chickens. The chickens were inoculated orally with IBDV at 1 day of age and via the air sac with E. coli at 1 week of age. In the groups given 1 x 10(5) cfu of E.coli of high virulence (Expt 1), mortality of IBDV-inoculated group (90%) was significantly higher than that in the non-IBDV-inoculated group (40%). The septicaemic lesions (splenic necrosis with fibrinous exudation) in the IBDV-inoculated-group were of significantly greater severity than those in the non-IBDV-inoculated group. The lymphocytic depletion in the bursa of Fabricius was most severe in the group inoculated with both IBDV and E. coli, then in descending order, in the group inoculated with IBDV alone and with E. coli alone. Lymphocytic depletion of the thymus was caused mainly by E. coli infection while IBDV induced mild lymphocytic depletion of the thymus. In Expt 2. the groups given 1 x 10(9) cfu of E. coli of low virulence revealed mortality of 50% when inoculated with IBDV and 10% when non-IBDV-inoculated. This study suggests that IBDV may increase the chickens' susceptibility to septicaemic infections produced by E. coli strains of high and low virulence and that IBDV and E. coli may induce additively marked lymphocytic depletion in the bursa of Fabricius and thymus.

    The objective of this study was to survey members of the American College of Rheumatology (ACR) regarding intra-articular and soft tissue (musculoskeletal [MSK]) injections and to determine if injection techniques vary depending on type of practice and years of experience. A survey was e-mailed to the members of the ACR to obtain demographics of the respondents, MSK injection practices, and adverse events seen. The most common indications for MSK injections were rheumatoid arthritis, osteoarthritis, and bursitis. Written consent and time-out procedures were more common in academic/government practices when compared with private practice. There was variation in the type of corticosteroid used. The most common preparations were methylprednisolone actetate (45.0%), triamcinolone acetonide (26.1%), triamcinolone hexacetonide (22.1%). This survey showed good agreement on the dosage of corticosteroid for MSK injections; however, as years of experience increased, clinicians were more likely to prescribe lower doses for shoulder and knee injections. In this survey of ACR members, we found self-reported differences in the type of corticosteroid used for MSK injections. There was general agreement on frequency of injections, but more experienced practitioners reported using lower doses of corticosteroid.

    Full Text Available It was intended to reveal the time dependent power generation under different loads for two different solar panels under the conditions of Bursa province in between August 19 and 25, 2014. The testing sets include solar panels, inverter, multimeter, accumulator, regulator, pyranometer, pyrheliometer, temperature sensor, and datalogger. The efficiency of monocrystalline and polycrystalline solar panels was calculated depending on the climatic data’s measurements. As the result of the study, the average performances of monocrystalline and polycrystalline panels are 42.06 and 39.80 Wh, respectively. It was seen that 87.14 W instantaneous power could be obtained from monocrystalline solar panel and that 80.17 W instantaneous power could be obtained from polycrystalline solar panel under maximum total radiation (1001.13 W/m2. Within this frame, it was determined that monocrystalline solar panel is able to operate more efficiently under the conditions of Bursa compared to polycrystalline solar panel. When the multivariate correlations coefficients were examined statistically, a significant relationship in positive direction was detected between total and direct radiation and ambient temperature on energy generation from monocrystalline and polycrystalline panel.

    Full Text Available The objective of the present study was to assess the development of broiler chicks during the first week post-hatching when reared at three different environmental temperatures. A total of 480 day-old chicks were placed in three environmentally controlled rooms (20, 25 and 35°C from 1 to 7 days of age. Body weight gain, feed and water intake, as well as liver, gizzard, heart, yolk sac and bursa of Fabricius weights were measured daily. Tibia and femur bones were weighed and their length and width (medial diameter were also obtained. The chicks reared at 20º C had lower weight gain and ingested less food than chicks reared at 25°C and less water than chicks kept at 35°C. Relative weights of the liver, heart, and gizzard were affected by environmental temperature, whereas yolk sac and bursa of Fabricius relative weights were not. The data showed that all bone parameters increased with bird age. Environmental temperature did not affect tibia or femur width, however a significant increase in bone weight and length occurred with increasing environmental temperature. These results indicate that brooding temperature of 20°C during the first seven days post-hatching was stressful decreasing broiler bone development and reducing chicks body weight.O presente trabalho teve como objetivo estudar o efeito de diferentes temperaturas-ambiente durante a primeira semana de vida de pintos de corte sob parâmetros zootécnicos, desenvolvimento visceral e crescimento ósseo.

    We aimed to evaluate the computer usage patterns of adolescents and to determine the effects of family life and parental attitude on these patterns. This was a descriptive, cross-sectional, population-based survey that included 935 children between 11 and 16 years of age who were students in the second level of primary school and their parents as well. The following instruments were used in the survey: student and parent questionnaires on computer usage patterns and the Parental Attitude Research Instrument (PARI) to assess parental attitudes towards child-rearing and family life. Of the study population, the majority of the students had a computer in their homes and spent a lot of time on the Internet. Parental control over the amount of time spent on the Internet and the websites that were visited had sometimes limited and contradictory effects on computer usage among the students. A democratic parental attitude was the best approach. Using the computer as a reward or punishment had a negative impact on the children's computer usage patterns. Although parents are confused concerning the benefits and harms of the Internet for their children and not certain how to manage their children's use of the computer and safe navigation of the Internet, a democratic parental attitude appears to be the best approach for reaching the most beneficial computer usage patterns for students.

    The vertebrate B-cell repertoire is capable of generating up to 10(9) different antibody molecules using relatively few germline immunoglobulin (Ig) gene segments. To generate diversity, humans and mice depend on combinatorial and junctional variations that occur during the gene rearrangement events that produce complete heavy and light chain Ig genes. This gene rearrangement process goes on continuously in the bone marrow, where each developing B cell assembles a unique heavy and light chain Ig gene from families of functional V, D, and J gene segments. In contrast, chickens have only single functional V and J segments for the heavy and light chain loci, and chicken Ig gene rearrangement occurs only during a brief period of embryonic development. A specialized organ involved in avian B-cell development, the bursa of Fabricius, provides the microenvironment necessary for the amplification of B cells that have undergone productive Ig gene rearrangements. Within the bursa, B cells also acquire somatic diversity within the rearranged V gene segments of the heavy and light chain Ig loci. Somatic diversification of chicken V gene segments occurs by intrachromosomal gene conversion, a DNA recombination process which involves unidirectional transfer of nucleotide sequence blocks from families of V region pseudogenes into the functional rearranged VH and VL genes.

The methodology used in this study is qualitative approach by investigating financial statements of agricultural public listed companies for the year 2011. Thestudy shows that the biological assets recorded in the public listed companies range from consumable biological assets and bearer biological assets. It also shows that many bearer biological assets need more than one reporting period to be ready to produce other biological assets or agriculture produce to be harvest. According to IAS 41, these biological assets should be recorded using fair value model, however this model will not be appropriate. This findings lead to another questions what is the valuation appropriate for biological assets which have different characteristics.

    Tandem running is a common recruitment strategy in ant species with small colony sizes. During a tandem run, an informed leader guides a usually naïve nestmate to a food source or a nest site. Some species perform tandem runs only during house hunting, suggesting that tandem running does not always improve foraging success in species known to use tandem running as a recruitment strategy, but more natural history information on tandem running under natural conditions is needed to better understand the adaptive significance of tandem recruitment in foraging. Studying wild colonies in Brazil, we for the first time describe tandem running in the ponerine ant Pachycondyla harpax (Fabricius). We asked if foragers perform tandem runs to carbohydrate- (honey) and protein-rich (cheese) food items. Furthermore, we tested whether the speed and success rate of tandem runs depend on the foraging distance. Foragers performed tandem runs to both carbohydrate food sources and protein-rich food items that exceed a certain size. The probability to perform a tandem run and the travelling speed increase with increasing foraging distances, which could help colonies monopolize more distant food sources in a competitive environment. Guiding a recruit to a food source is costly for leaders as ants are ~66% faster when travelling alone. If tandem runs break up (~23% of all tandem runs), followers do not usually discover the food source on their own but return to the nest. Our results show that tandem running to food sources is common in P. harpax, but that foragers modify their behaviour according to the type of food and its distance from the nest. Competition with other ants was intense and we discuss how tandem running in P. harpax might help colonies to build-up a critical number of ants at large food items that can then defend the food source against competitors.

    We conducted microtremor array surveys for shallow S-wave velocity profiles at 20 sites in Bursa, Yalova and Kocaeli provinces in the north-western part of Turkey to provide fundamental data to assess the seismic hazard in the area. All of the measurement sites were positioned very close to strong motion stations belonging to the Disaster and Emergency Management Presidency of Turkey (AFAD) in order to further understand site amplification factors in strong motion records. Of the 20 study sites, two were located in Yalova, four in Bursa and 14 in Kocaeli. We temporarily installed two small arrays to obtain simultaneous records of vertical microtremors. Then, the spatial autocorrelation method was applied to retrieve Rayleigh wave phase velocity curves in a frequency range from 1 to 30 Hz from the array records. The phase velocities in the western part of the Kocaeli area are low across a wide frequency range, while relatively high phase velocities are found in the eastern part of the Kocaeli province. The phase velocities in the Yalova and Bursa provinces are widely distributed suggesting large variations in soil conditions. The observed phase velocity curve at each site was inverted to a one-dimensional (1D) S-wave velocity profile to a depth of 100 m, using a hybrid heuristic inversion method. All the S-wave velocity profiles in the eastern Kocaeli area are similar; however, the sites in the western Kocaeli and Yalova-Bursa areas have profiles with different features from the others. Finally, we discuss amplification factors for S-waves using the inverted profiles. The dominant fundamental periods of the amplification factors were distributed in a frequency range from 0.7 to 5 Hz. The profiles obtained are also used to map average S-wave velocities in the study area, with an addition of existing data at strong motion stations of the AFAD.

    Full Text Available ABSTRACT. Chrysomya albiceps (Wiedemann and Hemilucilia segmentaria (Fabricius (Diptera, Calliphoridae used to estimate the postmortem interval in a forensic case in Minas Gerais, Brazil. The corpse of a man was found in a Brazilian highland savanna (cerrado in the state of Minas Gerais. Fly larvae were collected at the crime scene and arrived at the laboratory three days afterwards. From the eight pre-pupae, seven adults of Chrysomya albiceps (Wiedemann, 1819 emerged and, from the two larvae, two adults of Hemilucilia segmentaria (Fabricius, 1805 were obtained. As necrophagous insects use corpses as a feeding resource, their development rate can be used as a tool to estimate the postmortem interval. The post-embryonary development stage of the immature collected on the body was estimated as the difference between the total development time and the time required for them to become adults in the lab. The estimated age of the maggots from both species and the minimum postmortem interval were four days. This is the first time that H. segmentaria is used to estimate the postmortem interval in a forensic case.

    Diseases and injuries of several specific structures in the heel region have been an enduring focus of medicine: The anatomical terminology of many of these structures has not been established until recently. The aim of the study was a historical analysis of the advances of anatomical terminology of three selected morphological units in the heel region--the Achilles tendon, calcaneus and retrocalcaneal bursa. It starts with a critical evaluation of the mythological eposes, the Illiad and Odyssey, describing the exploits of heroes in the Trojan war, followed by a review of relevant terms used for the designation of selected heel structures in the Middle Ages as well as in the 18" and 19" centuries. Principal versions of Latin anatomical terms used for the denotation of the mentioned structures are discussed. Recently applicable Latin terms and their recommended English synonyms, according to the latest version of Terminologia Anatomica (1998) are summed up. It surveys examples of "not very appropriate" terms, which are frequently used in clinical literature. The authors consider the use of official anatomical terms (both Latin and English) as an important step for the improvement of the clinical expressions and formulations.

    Local injection of cortisone derivatives, sometimes combined with local anesthetics, is frequently administered in rheumatology as the treatment of choice in para-articular diseases or as an adjuvant to systemic therapy in the treatment of arthritis.One of the most frequent local corticosteroid injections administered in daily clinical practice by rheumatologists, orthopedic surgeons, physiatrists, sports medicine doctors and general practitioners is injection into the subacromialsubdeltoid bursa in the treatment of bursitis and anterior superior impingement syndrome of the shoulder.Before local corticosteroid injection is administered, it is important to identify possible contraindications and to examine the documentation provided by the patient. Absolute contraindications or those related to the procedure should be evaluated by the prescribing physician but also the physician performing the corticosteroid injection should evaluate possible contraindications to make sure that corticosteroid injection is feasible. The present paper describes the ultrasound (US) guided local corticosteroid injection procedure with particular attention to the equipment required, the position of the patient and the examiner as well as the approach. The main advantage of US guidance during corticosteroid injection is the possibility to identify vascular structures, nerves and tendons situated in the needle path in order to avoid these structures and be sure to inject the drug into the appropriate location. When all rules are complied with and the corticosteroid injection is carried out by an experienced physician, it is virtually painless and is performed in just a few minutes.

    Trochanteric bursa (TB) injection with local anesthetic and corticosteroid is a treatment for patients suffering from greater trochanteric pain syndrome. Both landmark (LM)-guided and ultrasound (US)-guided methods have been used, but their accuracies have not been determined. This study examined the accuracy of these injections with cadaveric dissection. Twenty-four hip specimens were randomized to receive TB injections with methylene blue under either LM-guided or US-guided approach. After dissection, the locations of the dye were classified into 3 categories: intrabursal, extrabursal, or combined intrabursal and extrabursal. The presence of dye in the intrabursal space with or without extrabursal leak was considered a successful injection. Accuracy was defined as the percentage of successful injection. The accuracies of the LM-guided and US-guided injection were 0.67 (95% confidence interval 0.35-0.90) and 0.92 (95% confidence interval 0.62-1.00), respectively, with no significant difference. This is the first cadaveric study examining the accuracy of both the US-guided and LM-guided techniques for TB injection. Future clinical studies are required to compare the outcomes of LM-guided and US-guided greater trochanteric pain syndrome injection.

Classical biological control of this psyllid vector should contribute to suppress their population. This research was conducted to determine the performance of Menochilus sexmaculatus Fabricius (Coleoptera: Coccinellidae when they were fed with D. citri. The larval performance index of M. sexmaculatus on D. citri compared with Aphis craccivora Koch (Hemiptera: Aphididae diet was 1.3.M. sexmaculatus fed with D. citri had lower fitness than those fed with A. craccivora as shown by longer larval stadium, lower adult dry weight, less number of egg produced and lower percentage of egg hatched. M. sexmaculatus grew best at the temperature of 27oC. Employing the exclusion procedure under field condition,M. sexmaculatus could reduce the population of D. citri up to 90%. These findings showed that theM. sexmaculatus could be a potential predator in reducing D. citri, particularly when the more preferred prey A. craccivora was not present.   Diaphorina citri Kuwayama (Hemiptera: Psyllidae merupakan kelompok Psyllid yang menularkan penyebab penyakit Huanglongbing yang sangat berbahaya pada tanaman jeruk.

    Full Text Available AIM/BACKGROUND: The aim of this study was to evaluate socio-demographic and fertility features, opinions on consanguinity, and the types of congenital disorders encountered in the babies of women in consanguineous marriages in the Nilufer Public Health Training and Research Area in the province of Bursa in northwest Turkey. METHODS: This case-control study was conducted between September 2005 and March 2006. The case group consisted of 393 women in consanguineous marriages in the Nilufer Public Health Training and Research Area; the control group consisted of 393 women of similar age living in the same neighborhoods but in non-consanguineous marriages. RESULTS: Women involved in a consanguineous marriage were on average younger than women in the control group. The mean numbers of pregnancies, births, stillbirths, and living and deceased babies were all significantly higher among the consanguineous marriages. When the sample and the control groups were compared, it was obtained that the women in the case group were socio-economically in a lower status statistically, by means of their husband’s and their own education and occupational status, than the women in the control group. The women in the case group were more likely to believe that consanguinity is not detrimental to a child’s health, and they approved of consanguineous marriages for their own children. These opinions were held despite there being a significantly higher incidence of congenital disorders among the children of the consanguineous marriages. CONCLUSION: Women there should be offered genetic counseling to help reduce the occurrence of children being born with congenital abnormalities. [TAF Prev Med Bull. 2008; 7(2: 107-112

    Full Text Available AIM/BACKGROUND: The aim of this study was to evaluate socio-demographic and fertility features, opinions on consanguinity, and the types of congenital disorders encountered in the babies of women in consanguineous marriages in the Nilufer Public Health Training and Research Area in the province of Bursa in northwest Turkey. METHODS: This case-control study was conducted between September 2005 and March 2006. The case group consisted of 393 women in consanguineous marriages in the Nilufer Public Health Training and Research Area; the control group consisted of 393 women of similar age living in the same neighborhoods but in non-consanguineous marriages. RESULTS: Women involved in a consanguineous marriage were on average younger than women in the control group. The mean numbers of pregnancies, births, stillbirths, and living and deceased babies were all significantly higher among the consanguineous marriages. When the sample and the control groups were compared, it was obtained that the women in the case group were socio-economically in a lower status statistically, by means of their husband’s and their own education and occupational status, than the women in the control group. The women in the case group were more likely to believe that consanguinity is not detrimental to a child’s health, and they approved of consanguineous marriages for their own children. These opinions were held despite there being a significantly higher incidence of congenital disorders among the children of the consanguineous marriages. CONCLUSION: Women there should be offered genetic counseling to help reduce the occurrence of children being born with congenital abnormalities. [TAF Prev Med Bull 2008; 7(2.000: 107-112

A biologia e o comportamento de P. nucleorum em A. arenaria e as taxas de predação de sementes foram descritas. Frutos encontrados sob 50 palmeiras foram coletados, mensalmente, em cada uma das duas áreas amostradas no PNRJ (mata de cordão arenoso e formação arbustiva aberta de Clusia Sclthdl, Clusiaceae. A avaliação dos cocos predados foi feita a partir da contagem dos orifícios de saída dos bruquíneos no campo, da emergência dos insetos no laboratório e da abertura dos frutos remanescentes. Através de observações e experimentos em 60 infrutescências, verificou-se que a oviposição de Pachymerus nucleorum em A. arenaria ocorre na infrutescência ainda em desenvolvimento diferentemente de registros na literatura em outras espécies de palmeiras, onde a oviposição ocorre nos frutos no chão. A predação dos frutos por P. nucleorum foi de 29,3% na área de mata de cordão arenoso e 20,6% na formação arbustiva aberta de Clusia. O ciclo de vida de P. nucleorum foi bastante longo e com amplitudes bem grandes dentro de uma mesma amostra, o que sugere uma possível diapausa em alguma fase do seu ciclo de vida.Seed predation on Allagoptera arenaria (Gomes O'Kuntze, 1891(Arecaceae palm by Pachymerus nucleorum Fabricius, 1972 was evaluated from September 2003 to September 2005 at the Parque Nacional da Restinga de Jurubatiba (PNRJ, Rio de Janeiro, Brazil.

    This study aimed to investigate the protective effect of γ-aminobutyric acid (GABA) on the development of immune function in chicks under heat stress (HS). One-day-old male Wenchang chicks were randomly divided into control (CK), HS and GABA+HS groups. The GABA+HS group was fed with 0.2 ml GABA solution (50 mg/kg) daily by oral gavage. The HS and GABA+HS groups were placed in 40 ± 0.5 °C environment for 2 h heat treatment from 13:00 each day. Blood samples were routinely taken at 14, 21, 28, 35 and 42 days respectively, and the contents of T and B lymphocyte subsets in the blood and tissue were analysed by flow cytometry after FITC/PE double staining; the plasma levels of interleukin (IL)-2, immunoglobulin (Ig)A, IgG and IgM were determined using ELISA. The thymus and the bursa of fabricius were also collected to analyse for organ index and observe for the changes in tissue microstructure. In addition, the chicks received primary and secondary immunizations with attenuated Newcastle disease (ND) vaccine (LaSota strain) at 7 and 28 days respectively; conventional hemagglutination inhibition (HI) assay was performed to monitor the titre changes in plasma antibody against ND virus in the birds. Our results indicated that the indices of both thymus and bursa of fabricius, the intactness of tissue structure and development, the plasma levels of IL-2, IgA, IgG and IgM, the titres of ND antibody, and the levels of B and T lymphocyte subsets in HS group were all significantly lower than those in CK group (p < 0.05). However, all above indices were significantly improved in GABA+HS group compared with those in HS group (p < 0.05). These results demonstrated that while HS seriously affected the development of immune function in Wenchang chicks, GABA effectively alleviated the damages of HS to the development of immune function in chicks.

    Full Text Available Abstract Cathelicidins are a major family of antimicrobial peptides present in vertebrate animals with potent microbicidal and immunomodulatory activities. Four cathelicidins, namely fowlicidins 1 to 3 and cathelicidin B1, have been identified in chickens. As a first step to understand their role in early innate host defense of chickens, we examined the tissue and developmental expression patterns of all four cathelicidins. Real-time PCR revealed an abundant expression of four cathelicidins throughout the gastrointestinal, respiratory, and urogenital tracts as well as in all primary and secondary immune organs of chickens. Fowlicidins 1 to 3 exhibited a similar tissue expression pattern with the highest expression in the bone marrow and lung, while cathelicidin B1 was synthesized most abundantly in the bursa of Fabricius. Additionally, a tissue-specific regulatory pattern was evident for all four cathelicidins during the first 28 days after hatching. The expression of fowlicidins 1 to 3 showed an age-dependent increase both in the cecal tonsil and lung, whereas all four cathelicidins were peaked in the bursa on day 4 after hatching, with a gradual decline by day 28. An abrupt augmentation in the expression of fowlicidins 1 to 3 was also observed in the cecum on day 28, while the highest expression of cathelicidin B1 was seen in both the lung and cecal tonsil on day 14. Collectively, the presence of cathelicidins in a broad range of tissues and their largely enhanced expression during development are suggestive of their potential important role in early host defense and disease resistance of chickens.

    1. This study was conducted to evaluate the effects of purine nucleosides on performance, gut morphology, intestinal enzymes and immunity functions in broiler chickens from 0 to 21 d of age. 2. A total of 360 1-d-old male chickens (Cobb 500) were randomly assigned to 4 treatments with 6 replications. Experimental diets consisted of a control without any additives and diets containing 0.1% pure adenosine, 0.1% pure guanosine and 0.1% equal aliquots of pure adenosine and guanosine. Two birds per cage (12 birds per treatment) were killed on d 11 and 21 in order to obtain serum samples for lipid profile, jejunal samples for morphology and mucosal immunity, digestive enzymes for epithelial maturation, and bursa and spleen samples for relative weight of immune organs to live body weight. 3. Birds receiving adenosine in their diets showed a significant increase in body weight and average daily gain and a significantly lower feed conversion ratio compared to the control birds. Villus height and width in jejunal samples also increased significantly in birds supplemented with adenosine. Although maltase was not affected by the experimental diets, adenosine increased alkaline phosphatase and aminopeptidase. Adenosine and its combination with guanosine boosted mucosal immunity as a result of increased IgA production. While there was no significant difference among treatments regarding the relative weight of the spleen, adenosine increased the relative weight of the bursa of Fabricius. Present results also showed that adding guanosine to broiler diets had no significant effects on growth, gut morphology, enzymes activity and immunological indices. 4. In conclusion, the improvement in growth performance, gut morphology and immunity in birds receiving adenosine demonstrated that pure adenosine could be a beneficial feed additive for the poultry industry, while guanosine showed no significant improvement.

    The objective of this study was to identify the causative agents of hepatitis observed in broiler chickens at processing. Livers of chickens from 16 broiler farms in Saskatchewan with gross lesions of hepatitis were collected at processing. In addition to routine bacterial isolation and histopathological examination, serologic studies for infectious bursal disease virus (IBDV) and Chicken anaemia virus (CAV), calculation of the ratio of the weight of the bursa of Fabricius (BF) to body weight (BBW), and histopathological examination of the BF were done. Of the 264 livers with gross lesions, 83% had multifocal to coalescing necrotizing hepatitis, 16% had perihepatitis, and 1% had hemorrhages. No definitive causative microorganisms were isolated from the hepatic lesions; however, no significant bacterial isolations were made. Bursal atrophy, low BBW ratio, and high titer of antibody against IBDV each correlated with the rate of total condemnations (P = 0.0188, P = 0.0001, and P = 0.0073, respectively). Nucleotide sequencing of IBDV isolated from the BF identified the variant strains Delaware-E and 586. Condemnation because of hepatic lesions was correlated with titer of antibody against IBDV and BBW (P = 0.016 and P = 0.027). The results of this study demonstrate that hepatic lesions in Saskatchewan chickens are not currently caused by a primary bacterial pathogen but are associated with indicators of immunosuppression that is likely due to variant IBDV.

    This work was conduced to determine the performance parameters of initial-phase turkey poults fed 7 different doses of aflatoxins in the diet. Three hundred thirty-six 1-d-old male turkey poults were used in this research. Turkeys were divided into 7 treatments according to aflatoxin doses (T1 = control; T2 = 20 ppb aflatoxins; T3 = 50 ppb; T4 = 100 ppb; T5 = 200 ppb; T6 = 500 ppb; T7 = 1,000 ppb). Birds were killed in 2 periods: half of them after 21 d of experiment and the remaining birds after 42 d of experiment. In both periods, the evaluated parameters were as follows: feed consumption, BW, relative weights of organs (liver, gizzard, heart, and bursa of Fabricius) and meat (breast and thighs), and clinical biochemistry parameters (total plasmatic proteins, albumin, uric acid, cholesterol, alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase). At 21 d of experiment, both feed consumption and BW were significantly affected by the aflatoxins present in the diet. Nevertheless, gizzard relative weight, total plasmatic proteins, and cholesterol levels were also affected. At the 42-d evaluation, besides feed consumption and BW, gizzard and liver relative weights and cholesterol levels were also affected by the presence of aflatoxins in the diet. Turkey poults are very sensitive to aflatoxin poisoning, because they are at least 3 to 6 times more sensitive to these contaminants than broilers.

    Birds and other animals are frequently killed by cars, causing the death of many million individuals per year. Why some species are killed more often than others has never been investigated. In this work hypothesized that risk taking behavior may affect the probability of certain kinds of individuals being killed disproportionately often. Furthermore, behavior of individuals on roads, abundance, habitat preferences, breeding sociality, and health status may all potentially affect the risk of being killed on roads. We used information on the abundance of road kills and the abundance in the surrounding environment of 50 species of birds obtained during regular censuses in 2001-2006 in a rural site in Denmark to test these predictions. The frequency of road kills increased linearly with abundance, while the proportion of individuals sitting on the road or flying low across the road only explained little additional variation in frequency of road casualties. After having accounted for abundance, we found that species with a short flight distance and hence taking greater risks when approached by a potential cause of danger were killed disproportionately often. In addition, solitary species, species with a high prevalence of Plasmodium infection, and species with a large bursa of Fabricius for their body size had a high susceptibility to being killed by cars. These findings suggest that a range of different factors indicative of risk-taking behavior, visual acuity and health status cause certain bird species to be susceptible to casualties due to cars.

    Full Text Available Infectious laryngotracheitis (ILT is an acute, highly contagious upper-respiratory infectious disease of chickens. In this study, a real-time PCR method was developed for fast and accurate detection and quantitation of ILTV DNA of chickens experimentally infected with ILTV strain LJS09 and naturally infected chickens. The detection lower limit of the assay was 10 copies of DNA. There were no cross reactions with the DNA and RNA of infectious bursal disease virus, chicken anemia virus, reticuloendotheliosis virus, avian reovirus, Newcastle disease virus, and Marek's disease virus. The real-time PCR was reproducible as the coefficients of variation of reproducibility of the intra-assay and the inter-assay were less than 2%. The real-time PCR was used to detect the levels of the ILTV DNA in the tissues of specific pathogen free (SPF chickens infected with ILTV at different times post infection. ILTV DNA was detected by real-time PCR in the heart, liver, spleen, lung, kidney, larynx, tongue, thymus, glandular stomach, duodenum, pancreatic gland, small intestine, large intestine, cecum, cecal tonsil, bursa of Fabricius, and brain of chickens in the infection group and the contact-exposure group. The sensitivity, specificity, and reproducibility of the ILTV real-time PCR assay revealed its suitability for detection and quantitation of ILTV in the samples from clinically and experimentally ILTV infected chickens.

    The aim of this study was to evaluate erythrocyte profile and microscopic changes effect of AF induces by low level (57.18 ppb) and chronic exposure (34 days) with administration of additive (Lactobacillus plantarum G7 and methionine). Aflatoxin-contaminated corn was prepared by inoculate Aspergillus flavus FNCC 6002 on corn. Total number of 576 broiler Lohman strain (MB202) unsexed DOC were allocated completely randomized into four treatments and 12 replicates, with 12 broiler chicks each. The treatments as follows: T1 = aflatoxin-contaminated diet, T2 = aflatoxin-contaminated diet + 1% of LAB (w/w), T3 = aflatoxin-contaminated diet + 0.8% of methionine (w/w), and T4 = aflatoxin-contaminated diet + 1% of LAB + 0.8% of methionine (w/w). The effect of treatments was evaluated using ANOVA and the difference among mean treatments were analyzed using DMRT. The result showed that administration of additives had no significant effect (P>0.05) on erythrocyte profile, liver, and bursa of Fabricius. The dose of additive in each treatment (T2, T3, T4) were insufficient to reduce adverse effect of chronic aflatoxicosis. It was concluded that the LAB dose for binding AF (57.18%) should be evaluated and the dose for methionine should be reduced for chronic treatment of aflatoxicosis.

    This experiment was conducted to evaluate the effects of different levels of sweet orange (Citrus sinensis) peel extract (SOPE) on humoral immune system responses in broiler chickens. Three hundred 1-day broilers (Ross-308) were randomly allocated to treatments varying in supplemental SOPE added in the drinking water. The experimental groups consisted of three treatments fed for 42 days as follows: a control treatment without feed extract, a treatment containing 1000 ppm of SOPE and a treatment containing 1250 ppm of SOPE. All treatments were isocaloric and isonitrogenous. Broilers were vaccinated with Newcastle disease virus (NDV), avian influenza (AI), infectious bursal disease (IBD) and infectious bronchitis virus (IBV) vaccines. Antibody titer response to sheep red blood cells (SRBC) was higher in the group fed 1250 ppm of SOPE (P < 0.05) as well as for immunoglobulin G (IgG) and IgM. Similarly, antibody titer responses to all vaccines were constantly elevated (P < 0.05) by SOPE enrichment in a dose-dependent manner. Relative weights of spleen and bursa of Fabricius were unaffected by treatments. Dietary SOPE supplementation may improve the immune response and diseases resistance, indicating that it can constitute a useful additive in broiler feeding. Thus, supplying SOPE in rations may help to improve relative immune response in broiler chickens. © 2014 Japanese Society of Animal Science.
