Kikuti, M;Langoni, H;Nobrega, DN;Corrêa, APFL;Ullmann, LS;
Journal of Venomous Animals and Toxins including Tropical Diseases , 2012, DOI: 10.1590/S1678-91992012000100016
Abstract: leptospirosis is a globally distributed emerging zoonosis. dogs are commonly affected and although other serovars can cause canine leptospirosis, leptospira interrogans serovar canicola is primary found in these animals. a retrospective study was conducted using a database of 1195 dogs tested for leptospira infection from 2003 to 2010 at the laboratory of zoonosis diagnosis at the veterinary hospital of s?o paulo state university (unesp) in botucatu, s?o paulo state, brazil. the seroprevalence of infected dogs was 20.08% (240/1195), and the most prevalent serovars were canicola (6.7%), copenhageni (5.0%), icterohaemorrhagiae (2.9%), autumnalis (2.9%), pyrogenes (2.8%), pomona (2.0%), hardjo (2.0%), australis (1.8%), bratislava (1.6%), cynopteri (1.4%), grippotyphosa (1.3%) and djasiman (1.0%). by univariate analysis, the variables age and breed were not statistically related to the infection, while gender and season were. the effects of gender were also noticeable related to serovars australis, canicola and hardjo. in multivariate analysis, the level of significance (p-value) of season was suppressed by gender, indicating possible collinearity between those two variables.

Abstract: tcome of the HORIZONS-AMI trial: bivalirudin enhances long-term survival in patients with ST-elevation myocardial infarction undergoing angioplasty Review (2516) Total Article Views Authors: Shah A, Feldman DN Published Date February 2012 Volume 2012:8 Pages 115 - 123 DOI: http://dx.doi.org/10.2147/VHRM.S23491 Received: 07 January 2012 Accepted: 25 January 2012 Published: 27 February 2012 Ashish Shah, Dmitriy N Feldman Greenberg Division of Cardiology, New York Presbyterian Hospital, Weill Cornell Medical College, New York, NY, USA Abstract: Cardiovascular disease is the leading cause of death in the US. For patients with ST-elevation myocardial infarction (STEMI), urgent reperfusion of the culprit arterial occlusion, often achieved via primary percutaneous coronary intervention (PCI), reduces post-MI mortality and other major adverse cardiovascular events (MACE). Adjunctive antithrombotic and antiplatelet therapies are used during PCI to reduce MACE rates. Currently, a variety of antithrombotic options are available for peri-procedural use. The most commonly used agents include unfractionated heparin or low molecular weight heparin ± glycoprotein IIb/IIIa inhibitors (GPI). These agents reduce the rates of peri-procedural ischemic and thrombotic events, though these benefits come at the cost of an increase in bleeding complications. Bivalirudin is a direct thrombin inhibitor with a short half-life and linear pharmacokinetics, which results in predictable serum concentrations and anticoagulant effect. Bivalirudin has emerged as an efficacious and safe alternative to heparin plus GP IIb/IIIa inhibitors in both stable coronary artery disease and acute coronary syndrome patients. In the HORIZONS-AMI trial, monotherapy with bivalirudin was compared with the combination of heparin and a GPI in a large population of patients with STEMI who underwent primary PCI. Bivalirudin treatment was associated with improved event-free survival at 30 days and reduced rates of major bleeding. Based on the results of the trial, the American College of Cardiology/American Heart Association and European Society of Cardiology guidelines have incorporated recommendations for bivalirudin use in the setting of STEMI. Recently, 3-year follow-up data from the HORIZONS-AMI cohort were published, demonstrating sustained benefits in patients treated with bivalirudin, including reduced rates of mortality, cardiovascular mortality, reinfarction, and major bleeding events. These results further support the use of bivalirudin in the setting of primary PCI for STEMI given that its benefits are maintained through long-term follow-up.

Dinámica poblacional de dos especies de anfípodos y su relación con la vegetación acuática en un microambiente de la cuenca del río Luján (Argentina)
Casset,María A; Momo,Fernando R; Giorgi,Adonis DN;
Ecolog?-a austral , 2001,
Abstract: the dynamics of two amphipod species in a freshwater micro-environment was studied. samples were taken monthly, during a whole year, from las flores stream, a luján river tributary. hyalella (mesohyalella) curvispina is a herbivore and feeds mainly on phytobenthos. hyalella (mesohyalella) sp. is a h. (m.) curvispina predator and uses macrophytes as a refuge. periphyton algal biomass reaches its maximum during june, the phytobenthos biomass reaches its maximum during october, and macrophyte biomass reaches its maximum between november and february. h. (m.) curvispina shows its maximum density (1267 individuals/m2) and its highest secondary production (2225 mg.m-2.month-1) in october coinciding with the phytobenthos' peak in biomass; its density correlates positively with phytobenthos abundance. h. (m.) sp. density (7067 individuals/m2) and secondary production (1018 mg.m-2.month-1) both peak in january. h. (m.) curvispina density is positively correlated with phytobenthos biomass. h. (m.) sp. density, biomass and secondary production are all positively correlated with macrophyte biomass.

Italian Journal of Animal Science , 2010, DOI: 10.4081/ijas.2007.1s.95
Abstract: An integrated analysis, using 20 microsatellite markers and 32 SNP markers belonging to the casein cluster has been carried out on 174 goats from 6 local goat breeds and populations from Southern Italy. Microsatellite markers provided 216 alleles (10.8 per locus; from 6.6 to 8.2 per breed). The average expected heterozygosity (He) was 0.732. Fis value (0.148) indicated a general heterozygosity deficiency. A high number of intragenic haplotypes (56) have been detected at casein loci, 25 at aS1 casein (CSN1S1), 12 at b casein (CSN2), 8 at aS2 casein (CSN1S2), 11 at k casein (CSN3), when 1% frequency was required for each breed. The breeds with higher production and management level, fixed the lowest number of combinations at casein loci (28). Molecular data have been used to calculate genetic distances and in clustering analysis.

Nepalese Journal of Ophthalmology , 2011, DOI: 10.3126/nepjoph.v3i2.5271
Abstract: Background: Ocular complications of herpes zoster ophthalmicus (HZO) may lead to substantial visual disability, severe post-herpetic neuralgia and rarely fatal cerebral complications. Aim : To identify the pattern of ocular manifestation in herpes zoster ophthalmicus. Materials and methods : A cross-sectional descriptive study was under taken including the clinically diagnosed cases of HZO. All of them underwent a complete ophthalmological evaluation. Results: Sixty-eight cases of HZO were examined, of which 37 (54.4 %) were male and 31 (45.6%) female. The mean age was 48.7 ± 18.5 years. Most of the patients (64.7 %) were above the age of 40 years. 77.94 % of the patients had some form of ocular involvement. Pain (77.9 %) was the commonest ocular complaint. In young patients less than 35 years, HIV was the most common risk factor (19.3 %).Visual status was good in the majority (73.5 %) of patients at presentation. Lid and adnexal findings (45.8 %) were most common ocular involvement followed by conjunctivitis (41.1 %). Corneal complication was seen in 38.2 % of cases, uveitis in 19.1 % and post-herpetic neuralgia (PHN) and secondary glaucoma each in 5.8 %. Conclusion : Eyelid and ocular adnexal involvement is most commonly found in patients with herpes zoster ophthalmicus followed by corneal complication and uveitis. There needs to be awareness of ocular involvement, which can be sight threatening, among the HZO patients and other medical departments and an increased emphasis on regular ophthalmic examination.

Information Manager (The) , 2009,
Abstract: Geography is a vital subject of the school curriculum which is creative, practical and intellectually stimulating. It tries to identify features on the field, their spatial pattern as well as give explanations to process which have generated the observed distributional patterns their location and provide scientific explanation for the evolution of such patterns. It deals with concepts needed to develop a sharp geographical mind capable of appreciating and solving important spatial problems. This article examines the importance and application of core concepts, nature and observations needed to help students at high school.

Abstract: The study focused on the effect of roads on the distribution of social amenities in Giwa Local Government Area of Kaduna State. It took a critical look at the road network connectivity and accessibility of the towns in Giwa in an attempt to understanding the level to which these road network components affected the distribution of social infrastructure. The data for this study was derived from secondary sources ; (i)The topology of the routes was extracted from the base map of the local government area, and this took some of the road network component. (ii)The statistical data on social amenities in the Local Government Area came from the various departments in the local government headquarters. A correlation analysis was applied on the data and the results tested for significance. Results of the study showed that the relationship between road network, and node accessibility and the distribution of social amenities, with a correlation coefficient explanation of 36.9%. The high disparity observed in the distribution of social amenities is the result of very poor connectivity index as revealed by the road network in the area.
