Association of acepromazine with propofol in giant amazon turtles Podocnemis expansa reared in captivity

PURPOSE: To evaluate the effects of different concentrations of an anesthetic association in giant amazon turtles (Podocnemis expansa).METHODS: Twenty healthy P. expansa of both sexes weighing between 1.0 and 1.5kg commercially bred in the Araguaia River Valley, Goias, Brazil, were separated into two groups (G1 n=10 and G2 n=10). Each group received a respective protocol: P1=acepromazine (0.5 mg/kg IM) and propofol (5 mg/kg IV) and P2=acepromazine (0.5 mg/kg IM) and propofol (10 mg/kg IV). The acepromazine was administered in the left thoracic member and the propofol in the cervical vertebral sinus. Assessments were made of the anesthetic parameters of locomotion, muscle relaxation, response to pain stimuli in the right thoracic and pelvic members and heartbeat.RESULTS: The anesthetic induction time was the same for both protocols (P1 and P2); however the P2 effects were of a longer duration.CONCLUSION: The sedation achieved with both protocols (P1 and P2) were satisfactory for the biological sample collection, physical examinations and minor surgeries on this species.

Association of dyslipidemia with intakes of fruit and vegetables and the body fat content of adults clinically selected for a lifestyle modification program

To investigate the relationship of dyslipidemia with demographic distribution and patterns of body fat and dietary intakes. From a universe of adults clinically selected for a lifestyle modification program 979 subjects (409 males and 570 females, 52.2 +/- 9.6 years) fulfilled the inclusion criteria. Overnight-fasting plasma was assayed (dry chemistry) for triglycerides (TG), total (TC) and HDL fraction of cholesterol given the non-HDL (n-HDL) fraction by the difference. Anthropometric assessment included body weight (kg), height (m), fat (bioelectrical impedance) and waist circumference (WC). Food intake was assessed by the 24-hour recall questionnaire and the food groups evaluated through recommendations from an adapted food pyramid. The chances of dyslipidemia from other variable changes were determined by logistic regression with p < 0.05. Normal values of BMI and WC were protective against all dyslipidemia markers whereas only hypercholesterolemia was influenced by diet (meat intake > 2 servings). Dietary intakes have protective effects against hypertriglyceridemia with whole grains, odds ratio (OR) 0.342 (Cl 95%, 0.154-0.760), fruits >= 3 servings (OR 0.523, 0.290-0.941) and vegetables >= 4 servings (OR 0.360, 0.176-0.735). In general total body and abdominal adiposity influenced all dystipidemia markers while dietary intake of fruits and vegetables protected against triglyceridemia.

Association of midazolam with ketamine in giant Amazon river turtles Podocnemis expansa breed in captivity

OBJETIVO: Avaliar os efeitos de duas associações anestésicas em tartarugas da Amazônia em (Podocnemis expansa). MÉTODOS: Vinte P. expansa, hígidas, de ambos os sexos, com massa corporal entre 1,0 e 1,5 kg, de um criatório comercial localizado no vale do rio Araguaia, Goiás, Brasil, foram distribuídas em dois grupos (G1 n=10 e G2 n=10). Cada grupo recebeu um protocolo sendo: P1 = midazolam (2 mg/kg IM) com cetamina (20 mg/kg IM) e P2 = midazolam (2 mg/kg IM) com cetamina (60 mg/kg IM), aplicados nos grupos G1 e G2, respectivamente. Os fármacos foram aplicados no membro torácico esquerdo. Os parâmetros clínicos avaliados foram: locomoção, relaxamento muscular, resposta aos estímulos dolorosos nos membros torácico direito e pelvinos e freqüência cardíaca. Essas avaliações foram feitas no tempo 0 (imediatamente após a injeção) e nos tempos 5, 10, 20, 30, 45, 60, 90, 120, 150 e 180 minutos após as injeções. RESULTADOS: O G2 apresentou maior freqüência cardíaca que o G1 e imobilização mais rápida e prolongada. CONCLUSÃO: As sedações obtidas por esses protocolos (P1 e P2) foram satisfatórias, sendo possível a contenção farmacológica para a coleta de amostras biológicas e exame físico em P. expansa.

Effect of the association of nystatin with a tissue conditioner on its ultimate tensile strength

Purpose: This study evaluated the ultimate tensile strength of a tissue conditioner without nystatin incorporation (GI - control group) and the same tissue conditioner modified by the addition of nystatin in two concentrations: GII - 500,000 International Units (U) and GIII - 1,000,000 U, in which each milligram of the medicament corresponded to 6079 U. Materials and Methods: Dumbbell-shaped specimens (N = 7) with a central cross-sectional area of 33 × 6 × 3 mm were produced for the three experimental groups. After polymerization following manufacturer's instructions, specimens were immersed in distilled water at 37°C for either 24 hours or 7 days and then tested in tension in the MTS 810 at 40 mm/minute. Data were analyzed by two-way ANOVA followed by Tukey's test, at 95% level of confidence. Results: The means (force-grams (gf) ± standard deviation) of the ultimate tensile strength were: GI - 634.29 ± 122.80; GII - 561.92 ± 133.56; and GIII - 547.30 ± 73.47 for 24-hour storage, and GI - 536.68 ± 54.71; GII - 467.50 ± 143.51; and GIII - 500.62 ± 159.76 for 7-day storage. There were no statistically significant differences among the three experimental groups (p > 0.05). The ultimate tensile strength means of all experimental groups after 7 days were significantly lower than those observed after 24 hours (p = 0.04). Conclusions: The results of this study suggest that the addition of nystatin into the tissue conditioner investigated in concentrations below 1,000,000 U did not affect its ultimate tensile strength.

The Deoxyhypusine Synthase Mutant dys1-1 Reveals the Association of eIF5A and Asc1 with Cell Wall Integrity

The putative eukaryotic translation initiation factor 5A (eIF5A) is a highly conserved protein among archaea and eukaryotes that has recently been implicated in the elongation step of translation. eIF5A undergoes an essential and conserved posttranslational modification at a specific lysine to generate the residue hypusine. The enzymes deoxyhypusine synthase (Dys1) and deoxyhypusine hydroxylase (Lia1) catalyze this two-step modification process. Although several Saccharomyces cerevisiae eIF5A mutants have importantly contributed to the study of eIF5A function, no conditional mutant of Dys1 has been described so far. In this study, we generated and characterized the dys1-1 mutant, which showed a strong depletion of mutated Dys1 protein, resulting in more than 2-fold decrease in hypusine levels relative to the wild type. The dys1-1 mutant demonstrated a defect in total protein synthesis, a defect in polysome profile indicative of a translation elongation defect and a reduced association of eIF5A with polysomes. The growth phenotype of dys1-1 mutant is severe, growing only in the presence of 1 M sorbitol, an osmotic stabilizer. Although this phenotype is characteristic of Pkc1 cell wall integrity mutants, the sorbitol requirement from dys1-1 is not associated with cell lysis. We observed that the dys1-1 genetically interacts with the sole yeast protein kinase C (Pkc1) and Asc1, a component of the 40S ribosomal subunit. The dys1-1 mutant was synthetically lethal in combination with asc1Δ and overexpression of TIF51A (eIF5A) or DYS1 is toxic for an asc1Δ strain. Moreover, eIF5A is more associated with translating ribosomes in the absence of Asc1 in the cell. Finally, analysis of the sensitivity to cell wall-perturbing compounds revealed a more similar behavior of the dys1-1 and asc1Δ mutants in comparison with the pkc1Δ mutant. These data suggest a correlated role for eIF5A and Asc1 in coordinating the translational control of a subset of mRNAs associated with cell integrity. © 2013 Galvão et al.

Effects of topical levobunolol or fixed combination of dorzolamide-timolol or association of dorzolamide-levobunolol on intraocular pressure, pupil size, and heart rate in healthy cats

Estudaram-se e compararam-se os efeitos do levobunolol, da combinação fixa de dorzolamida 2%-timolol 0,5% e da associação de dorzolamida 2% com levobunolol 0,5% sobre a pressão intra-ocular (PIO), o diâmetro pupilar (DP), a freqüência cardíaca (FC) e a hiperemia conjuntival em 18 gatos saudáveis. PIO, DP, FC e hiperemia conjuntival foram aferidos diariamente, em três horários distintos (9h, 14h e 18h). Três grupos foram formados (n=6) e um olho de cada animal recebeu, aleatoriamente, uma gota de levobunolol (L), ou a combinação comercial à base de dorzolamida-timolol (DT), ou a associação de dorzolamida com levobunolol (DL). Parâmetros basais foram aferidos no primeiro dia (dia 0). Nos quatro dias consecutivos, os fármacos foram instilados às 8h e 20h e os parâmetros aferidos nos mesmos horários. Todos os parâmetros decresceram significativamente em relação aos valores basais (P<0,001) e não se observou hiperemia conjuntival. O levobunolol reduziu significativamente a PIO, o DP e a FC e o foi o fármaco que mais reduziu a FC. Não se observou efeito sinérgico na redução da PIO quando a dorzolamida foi adicionada ao levobulol.

Niche-specific association of Aeromonas ribotypes from human and environmental origin

A total of 88 Aeromonas isolates from distinct locations and sources (39 from extraintestinal infections, 31 from diarrhoeic, ten from non-diarrhoeic faeces, all human, and eight from fresh water) were subjected to phenospecies identification, serotyping, ribotyping and detection of some virulence markers. The strains belonged to four different phenospecies marked by 19 O serogroups and 38 ribotypes. No strong correlation between these parameters was found, and no group, as defined by the typing methods, could be characterized with a particular set of virulence markers. There was a clear association of ribotypes with the source of the strains. Cluster analysis allowed the identification of a complex of ribotypes belonging to distinct but related sources, including clinical and environmental isolates. These results suggest that ribotyping may be an epidemiological tool suitable for the study of Aeromonas infections.
