Full Text Available This article aims to demonstrate the character of the pirate Theron, whose false name, Demetrius, in the novel is a philosopher’s name too, contains a satire against Demetrius the Cynic; by considering the whole account, I infer from it the novel has been composed in the reign of Trajanus.

Full Text Available An experiment on the immunization of Jambal Siam ( Pangasius hypophthalmus withIchthyophthirius multifiliis vaccine was conducted in the Laboratorium of Parasitic and Fish Diseases,Faculty Fisheries and Marine Science of Riau University, and Laboratorium of Fish Health of FacultyFisheries and Marine Science, IPB. The objective of the study was to enhance immune system of the fishfry on the ichthyophthiriasis diseases. The vaccine was prepared by prolonged treatment of theron in waterbath of 47°C for 30 minutes. The vaccine was administrated to fish by immersion in aquaria. A completelyrandomized design (CRD in factorial pattern (3 X 3 X 3 was carried out with dose and time as factors.Doses of treatment and time of immersion were of 1 ml/L, 2 ml/L and 3 ml/L as well as 15, 30 and 45minutes of treatment time respectively. To evaluate the effectiveness of vaccine in fish, a challenge test tofish was done at day 15 with theron 90.000 cell/ aquaria until rearing day 25 after vaccination. It revealedthat the best performance (p<0.5 were of dose 3 ml/L and time treatment of 15 minutes in that survivalrate of fish was 100% followed by dose 3 ml/L with time 45 minutes (63,3%. The total erythrocyte count,hematocrit level and hemoglobin of tested fish were fluctuated. The water quality were recorded including;dissolved oxygen range from 3,74 - 4,98 ppm; temperature 25 - 30°C and acidity of 4 - 6, quality were ofnormal range for fish. The optimal vaccine dose is 3 ml/l with 15 minute immersion.

Modulation of the toxicity of photons by non-conventional drugs

Bohm, L.; Theron, T.; Serafin, A.; Verheye, F.

The 3 drugs under investigation Pentoxifylline, Ouabain and Thalidomide are non-conventional in the sense that they have a low toxicity and do not damage DNA. Pentoxifylline reduces blood viscosity ad enhances peripheral blood flow. When combined with irradiation in a mouse rhabdomyosarcoma model we found markedly enhanced tumour growth delay and in cultured cells dose modifying factors for SF2 and alpha in the region of 1.2-1.7 (Strahlentherapie 1995;170:595-01). The drug also alters cell regulation by inhibiting the radiation induced G2/M block and suppressing control of DNA synthesis (Theron and Boehm, unpubl.). When Thalidomide was added in the absence of irradiation to the myelo-blastic cell line K-562 we found characteristic changes of cell morphology and cell surface markers suggesting differentiation and expression of a megacaryocytic lineage (Leukemia Research 1991;15:129-136). A summary of the current state of research is given. (authors)

Can the anti-inflammatory activities of β2-agonists be harnessed in the clinical setting?

Full Text Available Annette J Theron,1,2 Helen C Steel,1 Gregory R Tintinger,1 Charles Feldman,3 Ronald Anderson1 1Medical Research Council Unit for Inflammation and Immunity, Department of Immunology, Faculty of Health Sciences, University of Pretoria, 2Tshwane Academic Division of the National Health Laboratory Service, Pretoria, 3Division of Pulmonology, Department of Internal Medicine, Faculty of Health Sciences, University of the Witwatersrand and Charlotte Maxeke Johannesburg Academic Hospital, Johannesburg, South Africa Abstract: Beta2-adrenoreceptor agonists (β2-agonists are primarily bronchodilators, targeting airway smooth muscle and providing critical symptomatic relief in conditions such as bronchial asthma and chronic obstructive pulmonary disease. These agents also possess broad-spectrum, secondary, anti-inflammatory properties. These are mediated largely, though not exclusively, via interactions with adenylyl cyclase-coupled β2-adrenoreceptors on a range of immune and inflammatory cells involved in the immunopathogenesis of acute and chronic inflammatory disorders of the airways. The clinical relevance of the anti-inflammatory actions of β2-agonists, although often effective in the experimental setting, remains contentious. The primary objectives of the current review are: firstly, to assess the mechanisms, both molecular and cell-associated, that may limit the anti-inflammatory efficacy of β2-agonists; secondly, to evaluate pharmacological strategies, several of which are recent and innovative, that may overcome these limitations. These are preceded by a consideration of the various types of β2-agonists, their clinical applications, and spectrum of anti-inflammatory activities, particularly those involving adenosine 3',5'-cyclic adenosine monophosphate-activated protein kinase-mediated clearance of cytosolic calcium, and altered gene expression in immune and inflammatory cells. Keywords: adenylyl cyclase, corticosteroids, cyclic AMP, muscarinic

Effect of nanoclay particles on some physical and mechanical properties of soils

Full Text Available Introduction: As a mechanical tillage practices on soil preparation improve soil structure, increase in porosity, better distribution of soil aggregates and eventually modify the physical properties of soil. The use of nano-technology in agricultural science and its application in tillage for improving the physical properties and mechanical issues has grown substantially. Nanotechnology is an appropriate way to reduce soil limitations. However the nanoparticles are very small amounts in soil, due to features such as high surface area, surface charge (appearance and sometimes porous nano-engineering of physical-chemical properties of soil are affected significantly (Mohammadi & Niazian, 2013. To use of nanomaterials in the territory of a new issue (Taipodia et al., 2011. Small developments on the use of nanoparticles to improve soil quality and land reform have been taken (Theron et al., 2008. Clay soil was used to enhance the compressive strength (Yonekura & Miwa, 1993. Nanosilica particle effects were examined for increasing resistance against penetration and consolidation (Noll et al., 1992. In 2005, these particles were used to increase adhesion and reduce viscosity. It seemed that the adhesion of the particles was depended on Nanosilica (Mohammadi & Niazian, 2013. The use of nanomaterials showed that the increased pH and soil fertility, improved soil physical structure, and reduced mobility, availability and toxicity of heavy metals and other environmental factors and those that will stabilize the soil components and subsides the erosion in the mining pick, (Lal, 2008. In agriculture, the soil conditioner studies have shown that nanoparticles can mine the soil quality by increasing water-holding capacity, increasing silt and clay and improve levels of nutrients, and eliminate toxins, (Liu and Lal, 2012.In this study, the effect on some physical and mechanical properties of soil contain clay gradation, Atterberg limits, specifications
