    Viral inclusions in monocotyledons infected by maize streak and related geminiviruses (1993)

    Notes: Isolates of maize streak virus (MSV) were examined by thin-section electron microscopy in plants, assessed for characteristic features of infection and compared with other related geminiviruses infecting monocotyledons from Africa, islands in the Indian Ocean, and the Pacific Island of Vanuatu. Arrays of virus particles, often crystalline, were most often seen in the nucleus. The morphology of the nuclear crystalline arrays was characteristic of certain isolates or groups of isolates (strains). Infected nuclei could be seen in cells from the phloem parenchyma, vascular bundle sheath and mesophyll tissue, and also in epidermal guard cells of plants infected with the maize strain of MSV. The particle arrays varied in morphology from regular rows of virions forming distinctive blocks, to randomly arranged aggregates in certain areas of the nucleus. We consistently failed to find viral crystalline arrays associated with infection of panicum streak virus (PSV) and sugar cane streak virus (SSV) isolates either in these hosts or in maize. Occasionally arrays of MSV particles were found outside the nuclear envelope in physiologically active cells. Accumulations or sheets of MSV particles were seen lining the walls of some phloem companion cells. Crystalline aggregates of particles were frequently observed in the cell vacuole, after lysis of the nuclear membrane of dead cells which made up the chlorotic lesions, the typical symptom of virus infection. Virus preparations from all hosts contained typical geminate particles regardless of the morphology of the virion arrays. The effect on chloroplasts appeared to vary between isolates and this is discussed in relation to lesion colour. The arrangement of virions in the nucleus as a taxonomic character is diagnostic for MSV. Inclusions with crystalline structure found in sieve elements of infected plants were not immunogold labelled when thin sections were probed using antiserum to the virus particles.

    Seasonal detection of pear decline phytoplasma by nested-PCR in different pear cultivars (2003)
    Oxford, UK : Blackwell Science Ltd
    Plant pathology 52 (2003), S. 0 
    Details
    ISSN: 1365-3059
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Seasonal detection of pear decline phytoplasma was studied in three pear cultivars: Bartlett, Limonera and Blanquilla. Samples from 43 infected trees were collected monthly over 2 years and analysed by nested PCR. The three cultivars each showed a different pattern of phytoplasma detection. The maximum detection rate of pear decline phytoplasma occurred in December in the three orchards, and it remained high throughout the winter months. In spring, when new buds appeared and sap was produced, the detection rate decreased. Leaf midribs, buds and stems were compared to determine which sample was more reliable for phytoplasma detection. The best indicators were stems. The presence of phytoplasma in sieve tubes during the dormant season was determined by grafting. The results suggest that phytoplasmas could overwinter in shoots, with the implication that vegetative propagation during this period could also disseminate the disease.

    Rectus sheath hematoma: diagnostic classification by CT (1996)

    Notes: Abstract. A method of classification for hematomas of the rectus abdominis sheath (RSH) is proposed based on findings observed in CT in the 13 cases of RSH in the present study. Type I hematomas (five cases) are slight and do not require hospitalization. Type II (three cases) and type III (five cases) are moderate and severe hematomas, respectively, and do require hospitalization. The patients with type III hematomas were all undergoing anticoagulant therapy and presented with a picture of acute abdomen, and in all five cases blood transfusion was carried out. Ultrasonography and, in particular, CT permitted a correct diagnosis of RSH. RSH should be considered (anticoagulant therapy induced) in females with sudden abdominal pain to avoid unnecessary surgical intervention.

    Conservative treatment of large rectus sheath hematoma in patients undergoing anticoagulant therapy (2000)

    Notes: Abstract Background: The purpose of this study was to describe our experience in the conservative management of large rectus sheath hematoma (RSH) in patients undergoing anticoagulation therapy. Methods: This is a retrospective study of the medical histories of 12 cases of RSH (11 female, one male; mean age = 67.6 years). Seven patients were taking oral anticoagulants, three were taking intravenous unfractionated heparin, and two were taking subcutaneous low-molecular-weight heparin. Six patients had a history of coughing fits. Ultrasound examination and computed tomography (CT) was performed in all cases. Results: Clinically, the majority of patients presented acute abdominal pain, infraumbilical masses, and anemic syndrome. Ultrasonography demonstrated nine of the 12 cases of RSH, and CT showed the hematoma in all 12 cases. Type II (five cases) and type III (seven cases) indicate moderate and severe hematomas, respectively. Excessive anticoagulation was observed in eight cases, and coagulation within correct ranges was seen in the remaining four cases. In five patients the normalization of coagulation was achieved by administering vitamin K1 and fresh frozen plasma. All cases of type III hematoma required blood transfusion. Conservative treatment was effective in all cases. Conclusions: RSH must be suspected in women of advanced age undergoing treatment with anticoagulants who present the clinical triad of acute abdominal pain, infraumbilical mass, and anemic syndrome. CT is the examination of choice for the diagnosis of RSH. Early diagnosis of RSH permits conservative management, even in the case of large hematomas with hemodynamic repercussions and avoids unnecessary surgical intervention.

    Effects of vasopressin on electrolyte transport in lizard intestine (1990)
    Springer
    Journal of comparative physiology 159 (1990), S. 745-751

    Notes: Summary Vasopressin applied serosally had no effect on electrical parameters and unidirectional Na and Cl fluxes across anin vitro short circuited preparation of lizard ileum. Short circuit current (Isc) and transmural potential difference (PD) across colon were decreased by vasopressin and increased by cyclic AMP. Vasopressin increased the mucosal-to-serosal flux of sodium and chloride across short circuited colon. Cyclic AMP had no effect on the rate of Na absorption but reversed Cl absorption to secretion. Vasopressin enhanced the net absorption of water across the colon but had no effect on absorption across ileum. Cyclic AMP activity in homogenates of colon was not altered by vasopressin but was increased by theophylline. It is concluded that the colonic response of the lizard colon to vasopressin is mediated by a noncyclic AMP mechanism.

    Datos biológicos del jurel común (T.T.) de la plataforma del Atlántico Centro Oriental. (2022)

    Description: Este trabajo trata aspectos sobre la distribución del jurel común (Trachurus trachurus, Linné), su ciclo de maduración anual y épocas de desove, unificando distintas informaciones. Podemos suponer que el jurel común desove en el periodo de octubre hasta mayo y no durante todo el año como afirman algunos autores. También se plantea la posibilidad de una variación de carácter cíclico en la población de esta especie con respecto al reclutamiento de las clases anuales, las cuales influyen en el aumento o disminución de su biomasa. Cabe la posibilidad de una distribución según la edad por subregiones.
