RESUMO O Brasil possui mais de 1.800 espécies de aves catalogadas. Quando mantidos em cativeiro, esses animais podem ser susceptíveis a vários tipos de patógenos, inclusive como parasitos gastrointestinais. No entanto, a falta de informações sobre os principais tipos de parasitos que infectam esses animais e as relações parasito-hospedeiro acabam sendo fatores limitantes na manutenção da saúde dessas aves. O objetivo deste estudo foi descrever o levantamento de helmintos e protozoários de aves exóticas e silvestres cativas da região Nordeste do Brasil. Para isso, amostras fecais (n = 182 pools) foram coletadas de 656 aves em cativeiro, pertencentes a 9 ordens e a 53 espécies. As análises parasitológicas foram realizadas por técnicas de Mini-FLOTAC®, flotação em sacarose, exame direto e coloração de Ziehl-Neelsen, além da sedimentação por centrifugação. Todos os dados foram analisados usando o software InStat, com um nível de significância definido em P<0,05. Parasitos gastrointestinais foram encontrados em 84,07% (153/182; P<0,0001) das amostras analisadas. Foram identificados 18 tipos de parasitos, sendo os enteroparasitos o mais frequentes: Cryptosporidium sp. (52,28%; P= 0,008), coccídeos não esporulados (41,17%; P= 0,0001), Entamoeba sp. (46,40%; P= 0,0480), Giardia sp. (18,33%; P= 0,0001), Strongyloides sp. (19,60%; P= 0,0001) e Trichostrongylidae (16,33%; P= 0,0001). As aves de rapina (n=17, 94,44%; P= 0,0004) e os psitaciformes (n=12, 66,67%; P=0,0001) apresentaram os maiores percentuais de infecção por endoparasitos gastrointestinais. 1800 1 800 1.80 catalogadas cativeiro patógenos entanto parasitohospedeiro parasito hospedeiro isso n pools 65 5 MiniFLOTAC®, MiniFLOTAC Mini FLOTAC®, FLOTAC Mini-FLOTAC® sacarose ZiehlNeelsen, ZiehlNeelsen Ziehl Neelsen, Neelsen Ziehl-Neelsen centrifugação InStat P005 P 0 05 P<0,05 8407 84 07 84,07 153/182 153182 153 (153/182 P<0,0001 P00001 0001 analisadas frequentes sp 52,28% 5228 52 28 (52,28% 0,008, 0008 0,008 , 008 0,008) 41,17% 4117 41 17 (41,17% 0,0001, 00001 0,0001 46,40% 4640 46 40 (46,40% 0,0480, 00480 0,0480 0480 0,0480) 18,33% 1833 33 (18,33% 19,60% 1960 19 60 (19,60% 16,33% 1633 16 (16,33% 0,0001. . n=17, n17 (n=17 94,44% 9444 94 44 0,0004 00004 0004 n=12, n12 12 (n=12 66,67% 6667 66 67 P=0,0001 180 80 1.8 6 MiniFLOTAC® FLOTAC® Mini-FLOTAC P00 P<0,0 840 8 84,0 153/18 15318 15 (153/18 P<0,000 P0000 000 52,28 522 2 (52,28 0,00 00 41,17 411 4 (41,17 0000 0,000 46,40 464 (46,40 0048 0,048 048 18,33 183 3 (18,33 19,60 196 (19,60 16,33 163 (16,33 n=17 n1 (n=1 94,44 944 n=12 66,67 666 P=0,000 1.

Abstract Crude glycerin is a byproduct of the biodiesel industry and has been widely used in ruminant diets as a source of energy, usually in place of corn, primarily during periods of drought in tropical regions. The objective of this study was to evaluate the effect of including levels of the crude glycerin of low purity (0, 6, 12 and 18%) replacing corn in the diets of goats on the carcass characteristics, tissue composition, meat cuts yield and physicochemical parameters of meat. Forty males castrated without defined racial pattern goats an initial average weight of 19.70 ± 2.30 kg were slaughtered after 86 days. Diets content 0 and 6% crude glycerin promoted similar responses to the analyzed variables, except for pH and breast weight. No differences were observed to total digestible nutrients, slaughter body weight, commercial cut yield leg tissue composition and physicochemical parameters of meat. Crude glycerin can be included up to 12% without losses on carcass weight and meat cuts, leg composition, and meat quality. The inclusion of crude glycerin containing 63.06% glycerol and 45.57% lipids could be effective in partial replacement of corn in diets for confined goats in tropical areas.

Abstract The analysis of gait in animals is important for understanding movement disorders in various human pathologies, especially those that develop muscle fibrosis. In the search for treatment alternatives for this problem, essential oils have been studied. Among them, research involving the essential oil of Alpinia zerumbet (EOAz) has been shown to promote relaxation and improve muscle function. Therefore, this study aimed to evaluate the effect of EOAz on gait with muscle fibrosis in immobilized rats. 30 rats (Wistar) were divided into five groups of six animals each: control group (without fibrosis and without treatment), immobilization group (with fibrosis and without treatment), and EOAz treatment groups (with fibrosis and with treatment). The animals were immobilized for 15 days with an ankle plantar flexion orthosis. After this period, they were treated with the oil cutaneously for 30 days. The analysis of behavioral tests before treatment indicated a significant increase in the means of the immobilized groups about to with concerning the control. We conclude that EOAz was effective in improving gait after inducing muscle fibrosis in immobilized rats. Studies are needed to assess the oil’s effectiveness in the treatment of muscle fibrosis in human pathologies.

The goal of the present study was to compare pulmonary function test (PFT) and cardiopulmonary exercise test (CPET) performance in COVID-19 survivors with a control group (CG). This was a cross-sectional study. Patients diagnosed with COVID-19, without severe signs and symptoms, were evaluated one month after the infection. Healthy volunteers matched for sex and age constituted the control group. All volunteers underwent the following assessments: i) clinical evaluation, ii) PTF; and iii) CPET on a cycle ergometer. Metabolic variables were measured by the CareFusion Oxycon Mobile device. In addition, heart rate responses, peak systolic and diastolic blood pressure, and perceived exertion were recorded. Twenty-nine patients with COVID-19 and 18 healthy control subjects were evaluated. Surviving patients of COVID-19 had a mean age of 40 years and had higher body mass index and persistent symptoms compared to the CG (P<0.05), but patients with COVID-19 had more comorbidities, number of medications, and greater impairment of lung function (P<0.05). Regarding CPET, patients surviving COVID-19 had reduced peak workload, oxygen uptake (V̇O2), carbon dioxide output (V̇CO2), circulatory power (CP), and end-tidal pressure for carbon dioxide (PETCO2) (P<0.05). Additionally, survivors had depressed chronotropic and ventilatory responses, low peak oxygen saturation, and greater muscle fatigue (P<0.05) compared to CG. Despite not showing signs and symptoms of severe disease during infection, adult survivors had losses of lung function and cardiorespiratory capacity one month after recovery from COVID-19. In addition, cardiovascular, ventilatory, and lower limb fatigue responses were the main exercise limitations.

Objective: Positive psychology interventions (PPIs) incorporate principles of personal strengths with the view that mental health recovery transcends symptom relief. Severe psychiatric conditions, such as schizophrenia, may benefit from such interventions. This study aims to gather the current evidence on the impact of PPIs on increasing well-being in patients on the schizophrenia spectrum and assess reductions in negative or positive symptoms. Methods: A systematic review of PPI studies with schizophrenia-spectrum patients was carried out following PRISMA recommendations. The PubMed, PsycINFO, Web of Science, and Scopus databases were searched for relevant publications in order to understand the possible effects of these interventions on well-being measures and psychotic symptoms in this population. Results: Nine studies (four controlled) were included. Meta-analysis of the controlled studies showed a significant effect (p = 0.04) for improvement of well-being (Z = 2.01). Overall, the reviewed evidence suggests well-being improvement. The effect on reduction of negative symptoms was unclear. Conclusion: Used as an adjunctive therapy, PPIs appear to be a promising resource for patients on the schizophrenia spectrum, with possible effects on well-being and symptom reduction.

Exercise intolerance is the hallmark consequence of advanced chronic heart failure (HF). The six-minute step test (6MST) has been considered an option for the six-minute walk test because it is safe, inexpensive, and can be applied in small places. However, its reliability and concurrent validity has still not been investigated in participants with HF with reduced ejection fraction (HFrEF). Clinically stable HFrEF participants were included. Reliability and error measurement were calculated by comparing the first with the second 6MST result. Forty-eight hours after participants underwent the 6MST, they were invited to perform a cardiopulmonary exercise test (CPET) on a cycle ergometer. Concurrent validity was assessed by correlation between number of steps and peak oxygen uptake (V̇O2 peak) at CPET. Twenty-seven participants with HFrEF (60±8 years old and left ventricle ejection fraction of 41±6%) undertook a mean of 94±30 steps in the 6MST. Intra-rater reliability was excellent for 6MST (ICC=0.9), with mean error of 4.85 steps and superior and inferior limits of agreement of 30.6 and -20.9 steps, respectively. In addition, strong correlations between number of steps and CPET workload (r=0.76, P<0.01) and peak V̇O2 (r=0.71, P<0.01) were observed. From simple linear regression the following predictive equations were obtained with 6MST results: V̇O2 peak (mL/min) = 350.22 + (7.333 × number of steps), with R2=0.51, and peak workload (W) = 4.044 + (0.772 × number of steps), with R2=0.58. The 6MST was a reliable and valid tool to assess functional capacity in HFrEF participants and may moderately predict peak workload and oxygen uptake of a CPET.

RESUMO Diante da escassez de dados sobre a topografia e a sintopia das vísceras abdominopélvicas do tamanduá-bandeira (Myrmecophage tridactyla - Linnaeus, 1758), o presente estudo teve como objetivo elucidar essas características e compará-las com as demais espécies animais, mormente as domésticas. Utilizaram-se três espécimes, dois machos e uma fêmea, provenientes de doação da Polícia Militar Ambiental de Franca ao Laboratório de Anatomia Veterinária da Universidade de Franca, após óbitos por atropelamentos. Os animais foram fixados e mantidos em solução aquosa de formaldeído a 10%, seguidos de dissecação convencional das cavidades abdominopélvicas para posterior inspeção direta e descrição topográfica das vísceras, visando a análises comparativas com outras espécies, cujo posicionamento e cujas particularidades já são bem estabelecidos na literatura. Observou-se que a maioria das vísceras dessas cavidades possuem localização e sintopia similares aos animais domésticos, exceto os rins e os testículos. Diante da metodologia estabelecida e dos resultados obtidos, admite-se que mais espécimes de tamanduás-bandeiras, de ambos os gêneros, devam ser avaliados e registrados cientificamente, visando à confirmação dos dados da atual pesquisa e à preconização anatômica da cavidade abdominopélvica, visto que variações anatômicas individuais são passíveis entre animais da mesma espécie.

ABSTRACT In view of the scarcity of data about the topography and syntopy of abdominopelvic viscera of the giant anteater (Myrmecophage tridactyla - Linnaeus, 1758), the present study aimed to elucidate these characteristics and to compare them with the other animal species, especially the domestic ones. Three specimens, two males and one female, were donated by the Environmental Military Police of Franca to the Anatomy Veterinary Laboratory of the University of Franca, after death by road killings. The animals were fixed and maintained in aqueous 10% formaldehyde solution, followed by conventional dissection of the abdominopelvic cavities for subsequent direct inspection and topographic description of the viscera, aiming at comparative analyzes with other species, whose positioning and particularities are already established in the literature. It was observed that most of the viscera of these cavities have similar location and syntopy to domestic animals, except for the kidneys and testicles. In view of the established methodology and the results obtained, it is accepted that more specimens of anteater, both genera, should be evaluated and registered scientifically to confirm the data of the current research and anatomical preconization of the abdominopelvic cavity, inasmuch anatomical individual variation are possible between animals of the same species.

RESUMO A ordem dos Passeriformes é uma das mais pressionadas pelas ações antrópicas, especialmente as relativas ao tráfico de animais, que, devido às más condições de manejo e higiênico-sanitárias, favorecem a infecção dos espécimes por patógenos virulentos e zoonóticos, como cepas de Escherichia coli e Salmonella spp., cujo isolamento em suabes cloacais, bem como a análise dos genes de virulência das cepas de E. coli foram objetivos do estudo. Para isso, 120 Passeriformes silvestres nativos, recebidos pelo Cetas/CE, foram avaliados individualmente. As cepas isoladas foram submetidas a teste de disco difusão para determinação da sensibilidade aos antimicrobianos. Em etapa posterior, foi realizada PCR para a detecção de oito genes de virulência dos principais patotipos diarreiogênicos de E. coli. Quanto aos resultados, nenhuma cepa de Salmonella spp. foi isolada, no entanto a ocorrência de E. coli foi de 40,8%. Foi observada elevada resistência, principalmente aos antimicrobianos tetraciclina, ampicilina e sulfazotrim, ocorrendo multirresistência em 42,8% das cepas. Pela análise molecular, foram diagnosticados quatro entre os nove genes pesquisados, com a identificação de EPEC típicas, EPEC atípicas, ETEC, EHEC e EAEC. Os resultados apontam para a importância de Passeriformes como possíveis disseminadores de zoonoses.

ABSTRACT The order Passeriformes is one of the most pressured by anthropic actions, especially those related to animal trafficking. Due to poor sanitary and hygienic conditions, the infection of the specimens is favored by virulent and zoonotic pathogens such as strains of Escherichia coli and Salmonella spp., whose isolation in cloacal swabs as well as the analysis of the virulence genes of E. coli strains were the objectives of the study. For this, 120 native wild Passeriformes, received by CETAS/CE were individually evaluated. The isolated strains were submitted to diffusion disc test to determine sensitivity to antimicrobials. In a later stage, PCR was performed for the detection of eight virulence genes from the main E. coli diarrhoeagenic pathogens. Regarding the results, no strain of Salmonella spp. was isolated; however, the occurrence of E. coli was 40.8%. High resistance was observed, mainly to the antimicrobials Tetracycline, Ampicillin and Sulfazotrim, with multi-resistance in 42.8% of the strains. By molecular analysis, four of the nine genes were diagnosed, identifying typical EPEC, atypical EPEC, ETEC, EHEC and EAEC. The results point to the importance of Passeriformes as possible disseminators of zoonoses.

ABSTRACT It was determined by the total collection of excreta method, with broilers from 22 to 32 days of age, the coefficients of apparent metabolism of dry matter, crude protein and crude energy and apparent metabolizable energy corrected for zero nitrogen balance (AMEn) of the ethanol co-products of corn: acid oil and dried distillery grains with soluble (DDGS). The DDGS and corn acid oil presented nutritional metabolization coefficients ranging from 43 to 83% and AMEn equal 2393.5 and 7859.2kcal/kg respectively, and may be food alternatives to soybean meal and soybean oil.

The objective of this study was to verify the agreement between pre-programmed and executed pacing during race walking and whether level of the athletes experience and performance influenced this relationship. Twenty-nine national and international race walkers participated in this study (14 males, 24.0±7.1 years old, and 15 females, 23.3±7.3 years old). Pre-programmed pacing for 10- and 20-km official walking races was self-selected via demonstrative pacing charts prior to races, while executed pacing was analyzed by a specialist investigator via an individual plot of current velocity versus distance. There was no agreement between pre-programmed and executed pacing (P=0.674). There was no association between the ability to match the pre-programmed pace with the executed pace and race walking experience or level of performance. Low- and high-performance athletes pre-programmed a similar pacing profile (P=0.635); however, high-performance athletes generally executed an even pacing strategy, while low-performance athletes generally adopted a positive pacing strategy (P=0.013). Race walkers did not faithfully match their pre-programmed with their executed pacing, and this seemed to be independent of previous experience and level of performance. High-performance athletes, however, tended to execute an even pacing strategy, even though this had not been pre-programmed.

We investigated the effect of caffeine ingestion combined with a 2-wk sprint interval training (SIT) on training-induced reductions in body adiposity. Twenty physically-active men ingested either 5 mg/kg of cellulose as a placebo (PLA, n=10) or 5 mg/kg of caffeine (CAF, n=10) 60 min before each SIT session (13×30 s sprint/15 s of rest). Body mass and skinfold thickness were measured pre- and post-training. Energy expenditure was measured at rest, during exercise, and 45 min after exercise in the first SIT session. Body fat was similar between PLA and CAF groups at pre-training (P>0.05). However, there was a significant decrease in body fat after training in the CAF group (−5.9±4.2%, P<0.05) but not in PLA (1.5±8.0%, P>0.05). There was no difference in energy expenditure at rest and during exercise between PLA and CAF groups (P>0.05), but the post-exercise energy expenditure was 18.3±21.4% greater in the CAF than in the PLA group (P<0.05). In conclusion, caffeine ingestion before SIT sessions induced a body fat loss that may be associated with higher post-exercise energy expenditure.

Abstract Microorganisms associated with organic management are essential in nutrient transformation and release for plant use. The present study aimed to isolate, identify and characterize plant growth promoting diazotrophic rhizobacteria associated with sugarcane under organic management. Rhizospheres of organic sugarcane varieties IAC 911099 and CTC4 were sampled and inoculated onto nitrogen free NFb and Burk media. The isolated microorganisms were screened in vitro concerning their ability to produce plant growth promoting factors. Eighty-one bacteria were isolated; 45.6% were positive for the nifH gene and produced at least one of the evaluated plant growth promotion factors. The production of indole-3-acetic acid was observed in 46% of the isolates, while phosphate solubilization was observed in 86.5%. No isolates were hydrogen cyanide producers, while 81% were ammonia producers, 19% produced cellulases and 2.7%, chitinases. Microorganisms belonging to the Burkholderia genus were able to inhibit Fusarium moniliforme growth in vitro. Plant growth promoting microorganisms associated with organic sugarcane, especially belonging to Burkholderia, Sphingobium, Rhizobium and Enterobacter genera, can be environmentally friendly alternatives to improve sugarcane production.

RESUMO O conhecimento do desenvolvimento mamário de um rebanho leiteiro é fundamental, pois relaciona-se à eficiência produtiva. Objetivou-se avaliar a associação dos parâmetros térmicos mamários com concentrações hormonais de búfalas em distintos estágios fisiológicos. Foram utilizadas 24 búfalas mestiças Murrah, em quatro grupos (n= 6): grupo 1 (bezerras), grupo 2 (novilhas), grupo 3 (gestantes) e grupo 4 (lactantes). A cada 28 dias, durante 4 meses, realizaram-se exames de termografia digital por infravermelho para verificar temperatura superficial dos corpos mamários craniais (CMCr) e caudais (CMC), das cisternas craniais (CGMCr) e caudais (CGMC) e tetas craniais (TGMCr) e caudais (TGMC). Foi aferida temperatura retal (TR) e colhido sangue para mensuração das concentrações plasmáticas do fator semelhante a insulina tipo-I, insulina (INS), hormônio do crescimento (GH), progesterona (P4) e estradiol. Grupos 1 e 2 apresentaram correlação de TR com CGMCr. No grupo 3, TR correlacionou-se com TGMCr, TGMC e concentrações plasmáticas de P4. No grupo 4, houve correlação de TR com CGMC, TGMCr e concentrações plasmáticas de INS e GH, e de TGMC com concentrações plasmáticas de GH. Nos quatro grupos, CGMCr correlacionou-se com CMCr e TGMCr, semelhantemente ao observado na porção caudal. Variações térmicas mamárias refletiram alterações fisiológicas aguardadas nos períodos avaliados.

ABSTRACT The knowledge of the mammary development of a dairy herd is key, since it is related to its productive efficiency. The objective of this study was to evaluate the association of mammary thermal parameters with hormonal concentrations of buffaloes at different physiological stages. Twenty-four Murrah crossbred buffaloes were used in four groups (n= 6): group 1 (calves), group 2 (heifers), group 3 (pregnant animals) and group 4 (lactating animals). Every 28 days, for 4 months, infrared digital thermography was performed to check the surface temperature of cranial (CrCM) and caudal (CCM) corpus mammae, cranial (CrC) and caudal (CC) cisterns and cranial (CrT) and caudal teats (CT). Rectal temperature (RT) was measured and blood was collected to measure plasma concentrations of insulin-like factor I, insulin (INS), growth hormone (GH), progesterone (P4) and estradiol. Groups 1 and 2 presented correlation of RT with CrC. In group 3, RT correlated with CrT, CT and plasma P4 concentrations. In group 4, there was correlation of RT with CC, CrT and plasma concentrations of INS and GH, and CT with plasma GH concentrations. In all four groups, CrC correlated with CrCM and CrT, similar to that observed in the caudal portion. The thermal changes in the mammary glands reflected the expected physiological changes in the evaluated periods.

Essential oils (EO) are volatile liquids responsible for the aroma of plants. Pterodon polygalaeflorus seeds have received widespread use in folk medicine for the treatment of inflammatory diseases. For this reason and because Pterodon polygalaeflorus seeds have great EO content, which is frequently pharmacologically active, the present study aimed to evaluate the antinociceptive effect of EO from Pterodon polygalaeflorus (EOPPgfl) and its acute toxic effects. The EEOPPgfl sample, which was extracted by steam distillation of the seeds, had a yield of 2.4% of the seeds weight and had, as major constituents, beta-elemene (48.19%), trans-caryophyllene (19.51%), and epi-bicyclosesquiphellandrene (12.24%). The EOPPgfl sample showed mild acute toxicity and its calculated median lethal dose (LD50) was 3.38 g/kg. EOPPgfl (20–60 mg/kg) showed antinociceptive activity as evidenced by several tests and inhibited writhing induced by acetic acid. The maximum effect was obtained with the 30 mg/kg dose and at 60 min after its administration. EOPPgfl also decreased formalin-induced nociception, as verified by the inhibition of the first and second phase of the formalin test. At 30 mg/kg, EOPPgfl also decreased thermally stimulated nociception. Nociception may be related to inflammatory and antiedematogenic activity and at doses ranging 10–100 mg/kg, EOPPgfl blocked dextran- and carrageenan-induced edema. The results demonstrated that EOPPgfl presented, at doses approximately 100 times smaller than LD50, an antinociceptive effect that probably was due to anti-inflammatory activities.

The aim of this study was to test the hypothesis that reduced pre-exercise carbohydrate (CHO) availability potentiates fat oxidation after an exhaustive high-intensity exercise bout. Eight physically active men underwent a high-intensity exercise (∼95% V̇O2max) until exhaustion under low or high pre-exercise CHO availability. The protocol to manipulate pre-exercise CHO availability consisted of a 90-min cycling bout at ∼70% V̇O2max + 6 × 1-min at 125% V̇O2max with 1-min rest, followed by 48 h under a low- (10% CHO, low-CHO availability) or high-CHO diet (80% CHO, high-CHO availability). Time to exhaustion was shorter and energy expenditure (EE) lower during the high-intensity exercise in low- compared to high-CHO availability (8.6±0.8 and 11.4±1.6 min, and 499±209 and 677±343 kJ, respectively, P<0.05). Post-exercise EE was similar between low- and high-CHO availability (425±147 and 348±54 kJ, respectively, P>0.05), but post-exercise fat oxidation was significantly higher (P<0.05) in low- (7,830±1,864 mg) than in high-CHO availability (6,264±1,763 mg). The total EE (i.e., exercise EE plus post-exercise EE) was similar between low- and high-CHO availability (924±264 and 1,026±340 kJ, respectively, P>0.05). These results suggest that a single bout of high-intensity exercise performed under low-CHO availability increased post-exercise fat oxidation, and even with shorter exercise duration, both post-exercise EE and total EE were not impaired.
