Asian Journal of Conservation Biology , 2012,
Abstract: The dragonflies and damselflies are a major insect group (Class Insecta; Order Odonata) associated with water courses. Odonate assemblages with reference to their habitat characters have not been widely studied in Sri Lanka. We have investigated odonate assemblages for a period of three months in selected localities in southern Sri Lanka with reference to the habitat characters. Bundala and Embillakala lagoons in Bundala National Park (A Ramsar wetland in Sri Lanka), “Kirala Kele” Eco-tourism Zone-Matara, Bandaththara marshland system-Matara, “Kirala Kele” Biological Garden-Ambalanthota and Kosgahadola stream which belongs to Mulatiyana Rain forest reserve were selected as study sites since these sites are important in conservation of biodiversity. A total of 28 species were identified during the study period. Our data reveals odonate assemblages specific to the studied habitats such as bushlands, marshlands, lagoons, flowing water bodies, stagnant water bodies and vegetation type (wet zone and dry zone). These data will be useful in future studies and conservation of biodiversity in the studied habitats.

Abstract: diphenylhydantoin (dfh) is known to yield cerebellar ataxia in chronically treated epileptic patient due to cerebellar atrophy with loss of purkinje cells. little attention has been paid in the literature to the acute dfh intoxication bearing cerebellar symptoms. we report a patient afflicted with complex partial seizures due to a left temporal cyst, who has been treated during the last two years with dfh 100 mg/day.due to the refractory characteristics of his seizures he was put on dfh 400 mg daily, and developed a pancerebellar syndrome. after surgical removal of the cyst his seizures entirely faded away and his cerebellar signs improved. nevertheless his neurological examination still showed trunkal and lower limbs ataxia. after one year of follow up his neurological picture did not change, while he was seizures free. tc and mri did not show cerebellar atrophy.

Se analizó aspectos de la distribución y estructura poblacional de Cyphocharax gilbert en cuatro diferentes áreas del cause bajo del Rio Paraíba do Sul y sus principales afluentes (22oS, 43oW), entre marzo de 1989 y febrero de 1990. La especie fue común en toda su extención, ocupando preferentemente los ríos grandes con aguas turbias y substrato de arena-lodo. Los ámbitos de longitud y frecuencia de tama os variaron con el lugar. Solo en una de las áreas hubo mayor proporción de hembras. Sin embargo, el análisis bimensual mostró una preponderancia de uno de los sexos en períodos antes y después del período reprodutivo en todas las áreas. Los machos prevalecen en los tama os inferiores y las hembras en los superiores. Huvo una prevalencia de jóvenes en un área usada probablemente como una región para alimentación y crecimiento.

Science of Sintering , 2004, DOI: 10.2298/sos0401011f
Abstract: The ternary compound of titanium-siliceous carbide Ti3SiC2, one of the representatives of Nan laminates, prepared by solid-phase sintering is investigated in compact and porous (q=0.03-0.41) states. Features of its short-term and long-term hardness (Р=10 N) behavior in the temperature range from 20 to 1200 С at a holding time of 1-60 min were studied. It is shown that a temperature of about 700°С and holding time under load of about 10 min are critical values of the indentation procedure that correspond to an intensive decrease of hardness. The presence of porosity results in a decrease in hardness. a deformation scheme of compact and porous titanium-siliceous carbide Ti3SiC2 in the temperature range from 20 to 1200 С is proposed. .
A genome scan to detect QTL affecting dairy traits in a dairy sheep backcross Sarda x Lacaune population

Italian Journal of Animal Science , 2011, DOI: 10.4081/ijas.2003.s1.31
Abstract: Recently in Mediterranean countries as France, Italy and Spain, dairy sheep selection has been efficiently oriented towards milk yield and milk composition. More attention has been now paid to traits related to the reduction of production costs (milkability, functional traits, longevity), health (resistance to mastitis or parasitic diseases), safety of food (reduction in contaminants) and quality (milk fatty acids composition). Therefore, research combining classical quantitative approach and QTL detection is needed, either on-farm by implementing experimental recording schemes......

Abstract: the purpose of the present work was to study cytological and biochemical characteristics of the peritoneal fluid in horses with experimentally induced peritonitis. sixty horses of undefined breed were randomly divided into t and c groups (treatment and control) and submitted to an experimental model of peritonitis, using median laparotomy. the treated group received trans-surgical treatment with antibiotics and antinflammatory substances. during the postoperative period both groups received equal treatment. samples of peritoneal fluid were collected 24h before surgery and afterwards, up to 120h, and macroscopical, cytological and biochemical evaluations were performed. the cytological and biochemical characteristics showed alterations that reflected the state of the mesothelial surfaces, as well as provided response to the applied medicinal therapy. such therapy induced a less acute inflammatory response, characterized by minor concentrations of total protein and fibrinogen, and a more accentuated phagocytical activity as well. it was also verified that the time of observation of cellular and biochemical changes should be longer than 120h after the peritoneal induction, in order to get complete information on the characteristics studied.

Abstract: The clinical case of a rare proarrhythmic effect of antiarrhythmic drugs with a poor prognosis (medication-induced atrial flutter in a patient with "malignant" Kent’s bundle) is presented. Radiofrequency ablation (RFA) is the most justified treatment method in patients with WPW-syndrome and "malignant" Kent’s bundle. RFA in descripted case has been postponed due to technical reasons. While waiting for RFA and after consideration of the potential risks and benefits the decision to use antiarrhythmic drugs to block the additional bundle was made. Paroxysm of broad-complex tachycardia developed on the third day of the treatment. It was regarded as a paroxysm of atrial fibrillation/flutter in the patient with WPW syndrome induced by taking anti-arrhythmic drugs class 1C (allapinine). Review of the literature on the atrial fibrillation induced by antiarrhythmic of 1C class, and association of atrial fibrillation with WPW-syndrome is presented.

Abstract: O objetivo deste trabalho foi estudar características citológicas e bioquímicas do líquido peritoneal de eqüinos utilizando-se 60 animais sem ra a definida, divididos aleatoriamente em dois grupos, tratado e controle, submetidos a um modelo experimental de peritonite, utilizando-se a laparotomia mediana. O grupo-tratado recebeu tratamento transcirúrgico com antibióticos e antinflamatórios. No período pós-operatório ambos os grupos receberam o mesmo tratamento. Foram colhidas amostras de líquido peritoneal 24h antes da cirurgia e, posteriormente, até 120h, sendo realizadas avalia es macroscópicas, citológicas e bioquímicas. As características citológicas e bioquímicas mostraram altera es que refletiram o estado das superfícies mesoteliais, assim como forneceram resposta à terapia aplicada. A terapia induziu uma resposta inflamatória menos intensa, caracterizada por menores concentra es de proteína total e fibrinogênio, bem como atividade fagocítica mais acentuada. Também foram verificadas modifica es quantitativas e qualitativas 12h após a indu o de peritonite. O tempo de observa o das modifica es celulares e bioquímicas deve ser superior a 120h após a indu o de peritonite para se obter informa es completas sobre as características estudadas.
