ESBL in positive hemoculture of a Southern-Brazil Teaching Hospital's Intensive Care Units / ESBL em hemoculturas positivas das Unidades de Terapia Intensiva de um Hospital Universitário do sul do Brasil

Bloodstream infections are among the most serious and frequent infections, and the people most exposed are patients in the Intensive Care Unit (ICU). ESBL (extended-spectrum beta-lactate) are resistant bacteria to penicillins, cephalosporins and monobactams. It´s necessary to know how often and which microorganisms are involved, checking their susceptibility. This study was carried out at the University Hospital. Data collection was performed in the Adult and Newborn ICUs, with assessment of microorganisms and their resistance profile. During six-month period, 156 samples were studied, and 42 were positive with microorganism isolation. Isolated species include Staphylococcus aureus, Staphylococcus epidermidis and Klebsiella pneumoniae. Many resistant to carbapenem.

Persistent organic pollutants distribution in plasma lipoprotein fractions

Abstract This study determines the associations among serum lipid profiles, risk of cardiovascular disease, and persistent organic pollutants. Using Gas chromatography technique, the intensity of toxic pollutant residues in serum samples of Hypertensive patients were measured. Based on statistical analysis, the effects of different covariates namely pesticides, age, systolic blood pressure, diastolic blood pressure, and lipid profile duration was checked using the logistic regression model. Statistical computation was performed on SPSS 22.0. The P-values of F-Statistic for each lipid profile class are greater than 0.01 (1%), therefore we cannot reject the null hypothesis for all cases. The estimated coefficients, their standard errors, Wald Statistic, and odds ratio of the binary logistic regression model for different lipid profile parameters indicate if pesticides increase then the logit value of different lipid profile parameters changes from -0.46 to -0.246 except LDL which increases by 0.135. The study reports a significantly increased threat of cardiovascular disease with increased concentrations of toxic pollutants.

Resumo Este estudo determina as associações entre o perfil lipídico sérico, o risco de doença cardiovascular e os poluentes orgânicos persistentes. Por meio da técnica de cromatografia gasosa, mediu-se a intensidade dos resíduos de poluentes tóxicos em amostras de soro de pacientes hipertensos. Com base na análise estatística, os efeitos de diferentes covariáveis ou seja, pesticidas, idade, pressão arterial sistólica, pressão arterial diastólica e duração do perfil lipídico foram verificados usando o modelo de regressão logística. O cálculo estatístico foi realizado no SPSS 22.0. Os valores P da estatística F para cada classe de perfil lipídico são maiores que 0,01 (1%), portanto não podemos rejeitar a hipótese nula para todos os casos. Os coeficientes estimados, seus erros padrão, estatística de Wald e odds ratio do modelo de regressão logística binária para diferentes parâmetros do perfil lipídico indicam se os pesticidas aumentam, então o valor logit de diferentes parâmetros do perfil lipídico muda de -0,46 para -0,246, exceto LDL, que aumenta em 0,135. O estudo relata um aumento significativo da ameaça de doença cardiovascular com aumento das concentrações de poluentes tóxicos.

Blood glucose profile as a rapid method for observing Koi carp (Cyprinus carpio) health status - case study of ectoparasites in Blitar, Indonesia / Perfil de glicose no sangue como um método rápido para observar o estado de saúde de carpa Koi (Cyprinus carpio) - estudo de caso de ectoparasitos em Blitar, Indonésia

Assessment of fish health is one of the efforts of farmers in minimizing losses due to disease. Rapid tests on fish health can be done through blood observations. This study aimed to determine the blood glucose profile of koi carp due to ectoparasite infestation from the level of blood glucose. The results showed that reported parasites from Blitar's koi carp were Trichodina, Dactylogyrus, Gyrodactylus, Myxobolus, Thelohanellus, Ichthyophthirius, and Argulus. Trichodina showed the highest prevalence (100%) in this case while Thelohanellus was the highest intensity level (93.8±16.3). The results of blood glucose level measurement based on parasite infestation levels showed no significant difference (p>0.05) though the health problems caused by parasites in light, medium or heavy infestation. This research also indicated that the blood glucose profile could be used as a rapid method to detect fish health caused by parasites. We suggest that other variables such as nutritional status, life stage or feeding must be conducted to ensure the glucose role in parasite identification as a rapid method for the future work.(AU)

A avaliação da saúde dos peixes é um dos esforços dos produtores para minimizar as perdas por doenças. Testes rápidos de saúde de peixes podem ser feitos por meio de observações de sangue. Este estudo teve como objetivo determinar o perfil glicêmico de peixes "koi", devido à infestação de ectoparasitos a partir do nível de glicemia. Os resultados mostraram que os parasitas relatados de peixes "koi" de Blitar foram Trichodina, Dactylogyrus, Gyrodactylus, Myxobolus, Thelohanellus, Ichthyophthirius e Argulus. Trichodina apresentou a maior prevalência (100%) neste caso, enquanto Thelohanellus foi o maior em nível de intensidade (93,8±16,3). Os resultados da medição do nível de glicose no sangue, com base nos níveis de infestação parasitária, não mostraram diferença significativa (p>0,05), apesar dos problemas de saúde causados ​​por parasitas em infestação leve, média ou pesada. Esta pesquisa também indicou que o perfil de glicose no sangue pode ser usado como um método rápido, para detectar a saúde dos peixes causada por parasitas. Este estudo também sugere que outras variáveis, como estado nutricional, estágio de vida ou alimentação, devem ser conduzidas para garantir o papel da glicose na identificação do parasita como um método rápido para trabalhos futuros.(AU)

Blood biochemical parameters of lambs fed diets containing cactus cladodes / Parâmetros bioquímicos sanguíneos de cordeiros alimentados com dietas contendo palma forrageira

This study aimed to evaluate the effects of partial replacement (750g/kg) of Tifton hay by two cactus cladodes (Nopalea or Opuntia) on the metabolic profile of lambs. Thirty-six uncastrated male Santa Inês lambs (22.0±2.9kg initial body weight) were distributed in a completely randomized design, with three treatments and 12 repetitions. The animals were fed a control diet (Tifton hay as exclusive roughage), Miúda cactus cladodes-based diet or Orelha de Elefante Mexicana (O.E.M.) cactus cladodes-based diet. Blood samples were collected one day before (baseline) and 45 days after the introduction of the tested diets. The Miúda cactus cladodes caused an increase (P=0.055) in the serum activity of the gamma-glutamyl transferase enzyme (53.66U/L) and in the blood content of glucose and fructosamine. The O.E.M. cactus cladodes caused lower (P=0.038) serum cholesterol content (41.33mg/dL). Regardless of the variety, there was a decrease (P=0.001) in the serum content of indirect bilirubin, urea, and sodium, and increase in the serum magnesium concentration. The partial replacement of the Tifton hay by Miúda or O.E.M. cactus cladodes in lamb feeding increases the enzyme activity, indicating liver and/or kidney changes, but does not cause relevant damage to energy, protein, and mineral metabolism.

Este trabalho teve como objetivo avaliar os efeitos da substituição parcial (750g/kg) do feno de Tifton por duas variedades de palma forrageira (Nopalea ou Opuntia) no perfil metabólico de cordeiros. Trinta e seis cordeiros Santa Inês, machos, não castrados (22,0 ± 2,9kg de peso corporal inicial), foram distribuídos em delineamento inteiramente ao acaso, com três tratamentos e 12 repetições. Os animais foram alimentados com dieta controle (feno de Tifton como volumoso exclusivo), dieta à base de palma forrageira Miúda ou dieta à base de palma forrageira Orelha de Elefante Mexicana (OEM). Amostras de sangue foram coletadas um dia antes (baseline) e 45 dias após a introdução das dietas testadas. A palma Miúda causou aumento (P=0,055) na atividade sérica da enzima gamaglutamiltransferase (53,66U/L) e no teor sanguíneo de glicose e frutosamina. A palma OEM causou menor teor (P=0,038) de colesterol sérico (41,33mg/dL). Independentemente da variedade, houve diminuição (P=0,001) do teor sérico de bilirrubina indireta, ureia e sódio, e aumento na concentração sérica de magnésio. A substituição parcial do feno de Tifton por palma Miúda ou por OEM na alimentação de cordeiros aumenta a atividade enzimática, o que indica alterações hepáticas e/ou renais, mas não causa danos relevantes nos metabolismos energético, proteico e mineral.

Emulsifier in Diets with Different Alternative Lipid Sources: Effects on the Health of Japanese Quails

The present research aims to evaluate the inclusion of an emulsifying additive based on mono- and diglycerides of fatty acids in diets with different lipid sources, studying its effects on duodenum histology, biometry of the digestive and reproductive tract, and blood biochemical profile of Japanese quails. The study was carried out in the experimental aviary of the Federal University of Grande Dourados, Mato Grosso do Sul, Brazil. The experimental design was completely randomized, with diets in a 3x2 factorial design with three different lipid sources (soybean oil, poultry fat, and beef tallow), either supplemented or not with an emulsifier. The birds that received a diet composed of poultry fat and an emulsifying additive had a larger gizzard. Animals that received a diet containing an emulsifier, regardless of the lipid source, had greater heart weight. The duodenum of animals that received bovine tallow in their diet showed a greater height and villus:crypt ratio. Biochemical parameters were not affected by either the lipid source or the inclusion of emulsifier in quail diets. The biochemical blood profile of birds in treatments did not show significant changes among all diets used. The use of soybean oil, bovine tallow, and poultry fat with or without the inclusion of an emulsifier does not show changes in the health and development of the quails' organs, which also indicates that the health of Japanese quails in the laying phase is kept in good standards.(AU)

Effect of strength training versus raloxifene on bone weight, blood glucose, lipid and antioxidant profile in ovariectomized rats

We compared the effect of the treatment with strength training (ST) and raloxifene (RALOX) on bone weight, blood glucose, lipid, and antioxidant profile in ovariectomized rats. Twenty-four Wistar rats were distributed into four groups: ovariectomy + VEHICLE (control); ovariectomy + RALOX; ovariectomy + ST; ovariectomy + RALOX + ST. Thirty days after ovariectomy, the animals underwent the treatment with RALOX (750 µcg day-1) and/or ST (three sessions week-1). Thirty days after, all groups were scarified, tibia and femur were weighed, and the blood was collected for analysis of the lipid profile, glucose, and antioxidants catalase (CAT) and glutathione (GSH). The ST group showed greater femur weight (0.82 ± 0.18 g) and RALOX + ST had greater tibia weight (0.61± 0.17 g) than CONTROL with femur weight of 0.65 ± 0.08 g and tibia of 0.49 ± 0.08 g with no differences between treatments (p > 0.05). ST group showed significantly higher catalase (181.7 ± 15.4 µM g-1) compared to the other groups. In contrast, the GSH value was lower in ST group (89.2 ± 8.1 µM g-1) compared to RALOX (175.9 ± 17.1 µM g-1) and RALOX + ST (162.8 ± 12.1 µM g-1), but the values of these two groups did not differ from CONTROL(115.3 ± 21.1 µM g-1). Total cholesterol did not differ between groups (p > 0.05), but exercise alone(54.3 ± 2.5 mg dL-1) or with RALOX (53.0 ± 1.5 mg dL-1) resulted in higher HDL cholesterol than CONTROL (45.5 ± 2.5 mg dL-1). Only RALOX+ST presented lower glucose (140.3 ± 9.7 mg dL-1) values than CONTROL (201.7 ± 30.6 mg dL-1). In conclusion, ST promotes similar benefits on bone and metabolic parameters compared to pharmacological treatment in ovariectomized rats.(AU)

Revision of some mensural measurements, food preference, and haematological parameters in breeding pairs of blue rock pigeon, Columba livia sampled from Punjab Pakistan / Revisão de algumas medidas mensurais, preferência alimentar e parâmetros hematológicos em pares de criação de pombo blue rock (Columba livia), amostragem de Punjab, Paquistão

The present study describes the haematological profile, feeding preference, and comparison of morphometric characters of blue rock pigeon (Columba livia) breeding pairs. For this purpose, 25 pairs (25 samples per sex) were sampled through Mist nets from district Okara and Bahawalnagar, Punjab, Pakistan. Birds were then anaesthetized with a combination of ketamine HCL (10 mg/kg) and diazepam (0.2 mg/kg) and subjected to morphometric measurements. 5µL blood also was taken from the jugular vein of each anaesthetized bird for haematological analysis. Few pairs were also dissected to remove gastrointestinal tracts (GITs) for food preferences. Results revealed that there are no significant differences in the haematological parameters and feeding preference of breeding pairs of Columba livia. The gut analysis further revealed, the major portion of gut contents consisted of pea and corn in most of the pairs. Regarding the mensural measurements, significant differences were recorded in the body weight, length of the longest primary feather, and chest circumference, whereas the rest of the studied parameters remain nonsignificant between sexes. So, it is concluded that apart from 3 morphometric parameters (body weight, length of longest primary feather and chest circumference), both sexes are alike in term of morphometry, haematology and food preference.

O presente estudo descreve o perfil hematológico, a preferência alimentar e a comparação de caracteres morfométricos de casais reprodutores de pombo-rocha (Columba livia). Para tanto, 25 pares (25 amostras por sexo) foram amostrados por meio de redes de névoa do distrito de Okara e Bahawalnagar, Punjab, Paquistão. As aves foram então anestesiadas com uma combinação de cetamina HCL (10 mg/kg) e diazepam (0,2 mg/kg) e submetidas a medidas morfométricas; 5 µL de sangue também foram retirados da veia jugular de cada ave anestesiada para análise hematológica. Poucos pares também foram dissecados para remover o trato gastrointestinal (GITs) para preferências alimentares. Os resultados revelaram que não há diferenças significativas nos parâmetros hematológicos e na preferência alimentar dos casais reprodutores de Columba livia. A análise intestinal revelou ainda que a maior parte do conteúdo intestinal consistia em ervilha e milho na maioria dos pares. Em relação às medidas mensurais, foram registradas diferenças significativas no peso corporal, comprimento da pena primária mais longa e circunferência torácica, enquanto os demais parâmetros estudados permanecem não significativos entre os sexos. Assim, conclui-se que além de três parâmetros morfométricos (peso corporal, comprimento da pena primária mais longa e circunferência torácica), ambos os sexos são semelhantes em termos de morfometria, hematologia e preferência alimentar.

Protective effects of Zizyphus oxyphyla on liver and kidney related serum biomarkers in (CCl4) intoxicate rabbits

Abstract The study was aimed to evaluate the therapeutic effects of Zizyphus oxyphyla leaves methanolic (ZOX-LME), on serum liver, kidney and hematology along with other serum parameters in Carbon tetrachloride (CCl4) intoxicated rabbits. Experimental animals were divided into five groups, six rabbits in each. These were: group NC (normal control), group, TC (toxic control) and group ST i.e. silymarine administered group at dose rate (50) mg/kg body weight (BW). Group ET1 and group ET2 treated with (ZOX-LME) at dose 200 mg/kg BW and 400 mg/kg BW. CCl4 administration caused significant (P> 0.05) impairment in serum liver enzymes, blood factors and other serum indices. Treatment with (ZOX-LME) significantly (P 0.05) reduced and normalized the levels of serum alanine transaminase (ALT) aspartate transaminase (AST) and alkaline phosphatase (ALP) and hematological indices. Also significant (P 0.05) reduction was observed in creatinine, urea, uric acid, blood urea nitrogen (BUN), and albumin and glucose concentrations. The altered levels of lipid profile and serum electrolytes (Ca, Mg, Cl, Na, K, and P) were significantly (P 0.05) change toward normal levels with (ZOX-LME) feeding. In addition (ZOX-LME) ingestion caused significant improvement in GSH, GST and CAT levels, while reducing the TBARS levels, exhibited antioxidant capacity. Also (ZOX-LME) showed increase inhibition against percent scavenging of 2, 2-diphenile-1-picrylehydrazyle (DPPH) free radical. Significant (P 0.05) normalizing effects were observed with high dose 400 mg/kg BW of (ZOX-LME and were equivalent to silymarine administered groups. The histological study of liver supported the hepatoprotective and renal curative activity of (ZOX-LME).

Resumo O estudo teve como objetivo avaliar os efeitos terapêuticos das folhas metanólicas de Zizyphus oxyphyla (ZOX-LME) no fígado, rim e hematologia séricos, juntamente com outros parâmetros séricos em coelhos intoxicados com tetracloreto de carbono (CCl4). Os animais experimentais foram divididos em cinco grupos, seis coelhos em cada. Estes foram: grupo NC (controle normal), grupo TC (controle tóxico) e grupo ST, isto é, grupo administrado com silimarina na taxa de dose (50) mg / kg de peso corporal (PC). Grupo ET1 e grupo ET2 tratado com (ZOX-LME) na dose de 200 mg / kg de peso corporal e 400 mg / kg de peso corporal. A administração de CCl4 causou prejuízo significativo (P > 0,05) nas enzimas hepáticas séricas, fatores sanguíneos e outros índices séricos. O tratamento com (ZOX-LME) reduziu significativamente (P 0,05) e normalizou os níveis de alanina transaminase (ALT), aspartato transaminase (AST) e fosfatase alcalina (ALP) e os índices hematológicos. Também foi observada redução significativa (P 0,05) nas concentrações de creatinina, ureia, ácido úrico, nitrogênio ureico no sangue (BUN), albumina e glicose. Os níveis alterados de perfil lipídico e eletrólitos séricos (Ca, Mg, Cl, Na, K e P) foram significativamente (P 0,05) mudando em direção aos níveis normais com a alimentação (ZOX-LME). Além disso, a ingestão de (ZOX-LME) causou melhora significativa nos níveis de GSH, GST e CAT, enquanto reduzia os níveis de TBARS, exibindo capacidade antioxidante. Também (ZOX-LME) mostrou inibição aumentada contra a eliminação percentual do radical livre 2, 2-difenila-1-picrilehidrazila (DPPH). Efeitos de normalização significativos (P 0,05) foram observados com altas doses de 400 mg / kg de peso corporal de (ZOX-LME) e foram equivalentes aos grupos administrados com silimarina. O estudo histológico do fígado confirmou a atividade hepatoprotetora e curativa renal de (ZOX-LME).

Analysis of the toxicological and pharmacokinetic profile of Kaempferol-3-O--D-(6-E-p-coumaryl) glucopyranoside - Tiliroside: in silico, in vitro and ex vivo assay

Abstract Tiliroside is a glycosidic flavonoid present in many plants species including Helicteres velutina K. Schum (Malvaceae sensu lato), commonly known in Brazil as pitó. This molecule has been shown to have many biological activities, however no study has been carried out to investigate the toxicity of this substance. The present work aimed to evaluate the possible cellular toxicity in silico, in vitro and ex-vivo of the kaempferol-3-O--D-(6-E-p-coumaroyl) glucopyranoside (tiliroside), through chemical structure analysis, toxicity assessment and predictive bioactive properties, using human samples for in vitro and ex-vivo tests. The in silico analysis suggests that tiliroside exhibited great absorption index when penetrating biological membranes. In addition, it also displayed considerable potential for cellular protection against free radicals, and anticarcinogenic, antioxidant, antineoplastic, anti-inflammatory, anti-hemorrhagic and antithrombotic activities. The assessment of the hemolytic and genotoxic effects of tiliroside showed low hemolysis rates in red blood cells and absence of cellular toxicity in the oral mucosa cells. The data obtained indicate that this molecule could be a promising therapeutic approach as a possible new drug with biotechnological potential.

Resumo O tilirosídeo é um flavonóide glicosídico presente em muitas espécies de plantas, incluindo Helicteres velutina K. Schum (Malvaceae sensu lato), conhecida no Brasil como pitó. Esta molécula mostrou ter muitas atividades biológicas, porém nenhum estudo foi realizado para investigar a toxicidade dessa substância. O presente trabalho teve como objetivo avaliar a possível toxicidade celular in silico, in vitro e ex-vivo do kaempferol-3-O--D- (6 -Ep-coumaroil) glucopiranosídeo (tilirosídeo), por meio de análises de estrutura química, toxicidade avaliação e propriedades bioativas preditivas, utilizando amostras humanas para testes in vitro e ex-vivo. A análise in silico sugere que o tilirosídeo exibe bom índice de absorção para penetrar nas membranas biológicas. Além disso, apresentou considerável potencial de proteção celular contra os radicais livres e com atividades anticarcinogênica, antioxidante, antineoplásica, antiinflamatória, anti-hemorrágica e antitrombótica. A avaliação dos efeitos hemolíticos e genotóxicos do tilirosídeo mostrou baixas taxas de hemólise nas hemácias e ausência de toxicidade em células da mucosa oral. Os dados obtidos indicam que esta molécula pode possuir uma abordagem terapêutica promissora como uma possível nova droga com potencial biotecnológico.

For this purpose, 25 pairs (25 samples per sex) were sampled through Mist nets from district Okara and Bahawalnagar, Punjab, Pakistan. Birds were then anaesthetized with a combination of ketamine HCL (10 mg/kg) and diazepam (0.2 mg/kg) and subjected to morphometric measurements. 5µL blood also was taken from the jugular vein of each anaesthetized bird for haematological analysis. Few pairs were also dissected to remove gastrointestinal tracts (GITs) for food preferences. Results revealed that there are no significant differences in the haematological parameters and feeding preference of breeding pairs of Columba livia. The gut analysis further revealed, the major portion of gut contents consisted of pea and corn in most of the pairs. Regarding the mensural measurements, significant differences were recorded in the body weight, length of the longest primary feather, and chest circumference, whereas the rest of the studied parameters remain nonsignificant between sexes. So, it is concluded that apart from 3 morphometric parameters (body weight, length of longest primary feather and chest circumference), both sexes are alike in term of morphometry, haematology and food preference.

Resumo O presente estudo descreve o perfil hematológico, a preferência alimentar e a comparação de caracteres morfométricos de casais reprodutores de pombo-rocha (Columba livia). Para tanto, 25 pares (25 amostras por sexo) foram amostrados por meio de redes de névoa do distrito de Okara e Bahawalnagar, Punjab, Paquistão. As aves foram então anestesiadas com uma combinação de cetamina HCL (10 mg/kg) e diazepam (0,2 mg/kg) e submetidas a medidas morfométricas; 5 µL de sangue também foram retirados da veia jugular de cada ave anestesiada para análise hematológica. Poucos pares também foram dissecados para remover o trato gastrointestinal (GITs) para preferências alimentares. Os resultados revelaram que não há diferenças significativas nos parâmetros hematológicos e na preferência alimentar dos casais reprodutores de Columba livia. A análise intestinal revelou ainda que a maior parte do conteúdo intestinal consistia em ervilha e milho na maioria dos pares. Em relação às medidas mensurais, foram registradas diferenças significativas no peso corporal, comprimento da pena primária mais longa e circunferência torácica, enquanto os demais parâmetros estudados permanecem não significativos entre os sexos. Assim, conclui-se que além de três parâmetros morfométricos (peso corporal, comprimento da pena primária mais longa e circunferência torácica), ambos os sexos são semelhantes em termos de morfometria, hematologia e preferência alimentar.

Effect of adding Spirulina platensis algae to small ruminant rations on productive, reproductive traits and some blood components

This experiment conducted using 20 Rahmani ewes at the last third of pregnancy in two equal groups. One group served as control, while the other group received Spirulina platensis(SP) at the rate of 0.5 gm 10 kg-1live body weight. The objective was to find out the effect of adding Spirulina platensisalgae to small ruminant rations on reproductive and productive traits and blood components of sheep. The experiments lasted for 120 days for both dams and their lambs after weaning. The findings proved that adding SP in ewes' diets had no effect on the average of live body weight change. Average milk yield was significantly (p <0.01) higher in the treatment group than the control. Lamb's birth weight and daily body gain of the treated group were significantly (p <0.01) higher than the control. Blood and serum picture profile of ewes were significantly higher when fed SP additive than the control.It could be concluded that the addition of SP to the ration of sheep positively preserved their health, productive and reproductive status as well as their lambs' growth rate. Also the additive improved the economic efficiency of treated animals by about 53.13%.(AU)

Analysis of the toxicological and pharmacokinetic profile of Kaempferol-3-O-ß-D-(6"-E-p-coumaryl) glucopyranoside - Tiliroside: in silico, in vitro and ex vivo assay / Análise do perfil toxicológico e farmacocinético de Kaempferol-3-O-ß-D- (6 "-E-p-cumaril) glucopiranosídeo - Tilirosídeo: ensaio in silico, in vitro e ex vivo

Abstract Tiliroside is a glycosidic flavonoid present in many plants species including Helicteres velutina K. Schum (Malvaceae sensu lato), commonly known in Brazil as "pitó". This molecule has been shown to have many biological activities, however no study has been carried out to investigate the toxicity of this substance. The present work aimed to evaluate the possible cellular toxicity in silico, in vitro and ex-vivo of the kaempferol-3-O-β-D-(6"-E-p-coumaroyl) glucopyranoside (tiliroside), through chemical structure analysis, toxicity assessment and predictive bioactive properties, using human samples for in vitro and ex-vivo tests. The in silico analysis suggests that tiliroside exhibited great absorption index when penetrating biological membranes. In addition, it also displayed considerable potential for cellular protection against free radicals, and anticarcinogenic, antioxidant, antineoplastic, anti-inflammatory, anti-hemorrhagic and antithrombotic activities. The assessment of the hemolytic and genotoxic effects of tiliroside showed low hemolysis rates in red blood cells and absence of cellular toxicity in the oral mucosa cells. The data obtained indicate that this molecule could be a promising therapeutic approach as a possible new drug with biotechnological potential.

Casos clínicos de infertilidade em gatos / Clinical cases of infertility in cats

A criação comercial de gato doméstico tem aumentado assim como a realização de estudos para melhorar a eficiência reprodutiva é uma realidade. O interesse pela identificação das falhas reprodutivas tem crescido, entretanto, os casos de infertilidade nos machos são escassos na literatura disponível. O histórico de infertilidade de um gato deve ser investigado cuidadosamente, pois pode estar associado a mudanças no manejo ou doenças. O diagnóstico dessas 'falhas reprodutivas' geralmente é simples, se realizada uma boa anamnese, exames, físico e andrológico, minuciosos, assim como exames complementares, entre eles hemograma completo, perfil bioquímico e testes para doenças infecciosas como FIV, FELV e FIP.(AU)

Commercial breeding of domestic cats has increased, and studies to improve reproductive efficiency are a reality. Interest in identifying reproductive failures has increased, however, cases of infertility in men are scarce in the available literature. A cat's history of infertility should be investigated carefully as it may be associated with changes in management or illness. The diagnosis of these 'reproductive failures' is usually simple if a good anamnesis, thorough physical and andrological examinations are carried out, in addition to complementary tests, including complete blood count, biochemical profile, tests for infectious diseases such as FIV, FELV, FIP.(AU)

Relationship of Linoleic and Alpha-Linolenic Acids on the Productive Performance and Serum Biochemical Profile of Japanese Quail Breeders

Linoleic (LA, 18:2) and alpha-linolenic (ALA, 18:3) acids are omega-6 and omega-3 polyunsaturated fatty acids considered essential to human and animal health. The optimum LA/ALA ratio for the production of fertile eggs in Japanese quail breeders has been little investigated. Thus, this study aimed to assess the effects of LA/ALA ratio on productive performance, egg quality, serum biochemical profile, body composition, and organ weight in Japanese quail. A completely randomized design was used. Birds were distributed into five treatments consisting of different LA/ALA ratios (1.48:1, 4.57:1, 7.63:1, 10.69:1, and 13.75:1), obtained by adding soybean (LA) and flaxseed (ALA) oils to the feed. Productive performance and egg quality were assessed in three cycles of 28 days each. At the end of the experiment, the birds were slaughtered and evaluated for biochemical profile, genital organ weights, and body composition. Data were subjected to analysis of variance and regression (p<0.05). LA/ALA ratio had no effect on productive performance or egg quality. Blood cholesterol in females and males and total triglycerides in females showed a quadratic response. Breeders fed the highest level of flaxseed oil (1.48:1) had the best serum levels of cholesterol and total triglycerides. Live weight and relative organ weights were not influenced by LA/ALA ratio. Differences in ash and crude protein levels were observed between groups, with LA increasing the deposition of these nutrients. It was concluded that LA/ALA ratio didn't affect productive performance or egg quality. However, based on the results of body composition, serum triglycerides, and cholesterol, it is recommended to use an LA/ALA ratio of 1.48:1 in diets.(AU)

Multilobular tumor of bone in bitches: clinical, histopathological, immunohistochemical and overall survival aspects

Background: Multilobular tumor of bone (MTB) is an unusual neoplasm with variable biologic behavior which originates primarily in bone tissues. Radiographs computed tomography (CT), and magnetic resonance imaging (MRI) are useful in diagnoses and surgical planning. Tumor removal with wide surgical margins is the treatment of choice. Immunohistochemistry has been shown as an important tool in veterinary oncology to define therapeutic and prognostic decisions. The goal of this study was to report 2 distinct cases of multilobular tumor of bone, their Cox-2 and Mib-1 immunohistochemical profile and its impact on overall survival. Case: Two bitches were presented at the Oncology Department of the Veterinary Hospital in the Veterinary School of Universidade Federal de Minas Gerais (UFMG). Both had a history of a progressive, painless, circumscribed, and firm facial mass. The 1st patient was a 8-year-old intact bitch mixed breed, weighing 50 kg, that presented a fast growing right infraorbital 3-cm mass, causing eye displacement. The 2nd patient was a 7-year-old spayed bitch Labrador retriever, weighing 28 kg, that presented a left temporal 8-cm mass. Neurologic examination of both bitches was normal. Skin over the nodules was strained, but with no ulceration. Radiographic exams of the head revealed lytic and proliferative bone reaction, with loss of cortical definition in both cases. These alterations were seen on the left zygomatic arch of the retrobulbar region, involving part of the mandible and of the nasal sinus lateral frontal bone in 1st patient, and on the right temporal process of the zygomatic bone in 2nd patient. The last one, also showed a granular solid mass with little contact with skull bones. Complete blood count, biochemistry profile, electrocardiogram, and 3-view thoracic radiographs were performed. Results were within normal ranges for the species and no signs of metastasis was seen on the radiographs. Location, size, and density of the mass, adjacent tissue compression, absence of cranial invasion, and lymph node size were rigorously evaluated with CT, allowing an individualized surgical planning to achieve complete mass removal and maintenance of the function of adjacent structures. Both animals were submitted to surgery. Both tumors were fixed on 10% neutral buffered formalin and sent to the Animal Pathology Department of UFMG for histopathological examination and margin assessment. Both tumors were diagnosed as grade I MTB. Tumor immunohistochemistry was performed to identify prognostic factors that could be used to better define therapeutic treatments and to try to clarify the discrepancy in disease progression between both tumors. The 1st patient expressed 20% of Mib-1 and was considered score 2 of Cox-2. The 2nd one expressed 5% of Mib-1 and was considered score 1 of Cox-2. Considering the diagnoses and histological characteristics of the tumors, it was decided for clinical follow-up of patients without additional therapeutic complementation. Even considering incomplete surgical margins in 2nd patient, adjuvant chemotherapy was not performed, due to low mitotic index and low histological grade. The 1st patient had an overall survival of 240 days, and death was due to recurrence and disease progression; and the 2nd did not show recurrence nor metastasis after 1200 days. Discussion: Proper and individualized surgical planning and histopathological evaluation are extremely important to guide treatment decisions. However, immunohistochemistry can be important in MTB cases, to help define which patients should be submitted to surgery alone and which patients could be benefited from adjuvant chemotherapy.
