RESUMO

Serotonin (5-HT) receptors have been implicated in social behavior in vertebrates. Zebrafish (Danio rerio) have been increasingly being used behavioral neuroscience to study the neurobiological correlates of behavior, including sociality. Nonetheless, the role of 5-HT2C receptors in different social functions were not yet studied in this species. Zebrafish were treated with the agonist MK-212 (2 mg/kg) or the antagonist RS-102221 (2 mg/kg) and tested in the social interaction and social novelty tests, conditional approach test, or mirror-induced aggressive displays. MK-212 increased preference for an unknown conspecific in the social investigation test, but also increased preference for the known conspecific in the social novelty test; RS-102221, on the other hand, decreased preference in the social investigation test but increased preference for the novel conspecific in the social novelty test. MK-212 also decreased predator inspection in the conditional approach test. While RS-102221 decreased time in the display zone in the mirror-induced aggressive display test, it increased display duration. Overall, these results demonstrate the complex role of 5-HT2C receptors in different social contexts in zebrafish, revealing a participation in social plasticity in vertebrates.

RESUMO

Virtual Reality (VR) has emerged as a new treatment approach in neurorehabilitation (NR). REAVITELEM Study is a specific NR intervention program based on VR at center (VRC) and tele-rehabilitation (TR) in Argentina. Methods First national multicenter study with a 12-week program intervention of VRC and TR. Participants were assessed at baseline, at 6th and 12th week. Phase I: recruitment and gather of 5 NR Centers from Argentina by the coordinator center (INEBA) to unify evaluation and intervention criteria. Phase II, all centers completed VRC an TR programs. Intervention was 30-minute session, twice a week for 12 weeks. Outcome measures: Expanded Disability Status Scale (EDSS), Fist and Key Pinch Dynamometry, Beck Depression Inventory-Fast Screen, Fatigue Severity Scale, Functional Independence Measure (FIM), International Questionnaire investigating Quality of life in MS (MusiQol) and a Visual Analogue Scale (VAS) of satisfaction after treatment. Results A total of 54 PWMS (23 males) were recruited for VRC. Afterwards, 14 completed TR. The mean age for VRC was 44.72 (SD ± 13.74) and 41.71 (SD ± 10.5) for TR. The median EDSS was 4, 75 for VR. At VRC, 42 have RRMS, 8 have SPMS and 4 PPMS. At TR, 13 have RRMS and 1 have SPMS. The VAS reported an excellent level of satisfaction after treatment with an average of 9, 02 (SD±1.35) in VRC and 9.42 (SD±0.66) in TR. There were significant differences for MusiQol, which improved from baseline to the post-intervention assessment at VRC (p=<0.001) and at TR (p = 0.004) as well as FIM post-intervention assessment at VCR (p = 0.02) and TR (p = 0.04). Conclusion this study suggest that the NR treatment based on VR in MS in Argentina, is an additional effective tool, which favors improvements in the level of functioning in activities of daily living, quality of life, mood, and satisfaction with the treatment.

RESUMO

Background: Enostosis like lesions are characterized by areas of intramedullary sclerosis affecting the long bones andtheir presence in any cases may be not associated with lameness. It has a migratory characteristic and, therefore there isthe occurrence of lameness at different sites from the initial lesion. Its etiology is speculative and has been attributed tointraosseous increased pressure, of Havers’ canals compression, stimulation of unmyelinated fibers and circulating plateletaggregates. Diagnosis is made through nuclear scintigraphy and associated with radiographic examination. This paperaims to report a clinical case on the use of scintigraphy for the reference diagnosis of enostosis-type injury and treatmentthrough surgical bone decompression.Case: A 2-year-old thoroughbred mare, weighing 483 kg, with a history of acute lameness of the left pelvic limb associatedwith the no previous signs of trauma and no noteworthy changes in radiographic and ultrasound images, was referred to theHorse Center Veterinary Clinic. In the examination of the locomotor system, the animal presented a 2/5 degree lamenessin a straight line, with accentuated exacerbation of the same after flexion of the left femoro-tibio-patellar joint. In addition,presented a reduction in the caudal phase of the stride and croup asymmetry associated with mild myopenia. The findingsof the scintigraphic exam characterized by intense focal area of hyperconcentration of medullary radiopharmaceutical inthe proximal third of the right third metatarsal, and multiple areas of hyperconcentration in the aspect proximal to thedistal third of the left tibia. In the radiographic images, multifocal radiopaque regions that coincided with the areas ofradiopharmaceutical hyperconcentration were observed. The initial treatment was based on rest, use of non-steroidal antiinflammatory drugs and acetylsalicylic acid. In the 60 days...

RESUMO

Serotonin (5-HT) receptors have been implicated in responses to aversive stimuli in mammals and fish, but its precise role is still unknown. Moreover, since at least seven families of 5-HT receptors exist in vertebrates, the role of specific receptors is still debated. Aversive stimuli can be classified as indicators of proximal, distal, or potential threat, initiating responses that are appropriate for each of these threat levels. Responses to potential threat usually involve cautious exploration and increased alertness, while responses to distal and proximal threat involve a fight-flight-freeze reaction. We exposed adult zebrafish to a conspecific alarm substance (CAS) and observed behavior during (distal threat) and after (potential threat) exposure, and treated with the 5-HT2C receptor agonists MK-212 or WAY-161503 or with the antagonist RS-102221. The agonists blocked CAS-elicited defensive behavior (distal threat), but not post-exposure increases in defensive behavior (potential threat), suggesting inhibition of responses to distal threat. MK-212 blocked changes in freezing elicited by acute restraint stress, a model of proximal threat, while RS-102221 blocked changes in geotaxis elicited this stressor. We also found that RS-102221, a 5-HT2C receptor antagonist, produced small effect on behavior during and after exposure to CAS.

RESUMO

The Tectona grandis L.f. (teak) is an important forest species with high economy value in Asia, Africa, and Latin America. In Latin America, Brazil is one of the countries with the most cultivated areas. The cultivation of teak turns out to be challenging because of its high nutritional demand and the need for seedling production by clonal propagation that includes about 90 days in the nursery phase. The optimization of seedling production is necessary for better results in the nursery and to enhance growth in the field. In this way, the well-known advantage of using microorganisms that promote plant development appears as a potential biotechnological approach to be explored and for the implantation of new areas of wood production. In this study, the inoculation of Bacillus subtilis as plant growth-promoting rhizobacteria (PGPR) was evaluated, and Rhizophagus clarus, an arbuscular mycorrhizal fungus (AMF), and the co-inoculation of these microorganisms in the teak seedling production phase can improve the development of commercial plantations under field conditions. Experiments were carried out under greenhouse and field conditions to evaluate four treatments based on the substrate inoculation of the seedlings. Treatments consisted of a non-inoculated control, PGPR inoculation, AMF inoculation, and PGPR + AMF inoculation. The results of the biometric evaluation of seedlings in the greenhouse showed that there was a significant difference in AMF inoculation and PGPR + AMF inoculation in terms of the specific root length and root density treatments, there was also a positive correlation between these two treatments and the absorption of some nutrients, such as P, N, K, Mg, Cu, Mn, and Zn. This response led to an increase between 4.75 and 11.04% in the field growth rate.

RESUMO

This study describes the embryonic development of Moenkhausia oligolepis in laboratory conditions. After fertilization, the embryos were collected every 10 min up to 2 h, then every 20 min up to 4 h, and afterwards every 30 min until hatching. The fertilized eggs of M. oligolepis measured approximately 0.85 ± 0.5 mm and had an adhesive surface. Embryonic development lasted 14 h at 25ºC through the zygote, cleavage, blastula, gastrula, neurula, and segmentation phases. Hatching occurred in embryos around the 30-somites stage. The present results contribute only the second description of embryonic development to a species from the Moenkhausia genus, being also the first for this species. Such data are of paramount importance considering the current conflicting state of this genus phylogenetic classification and may help taxonomic studies. Understanding the biology of a species that is easily managed in laboratory conditions and has an ornamental appeal may assist studies in its reproduction to both supply the aquarium market and help the species conservation in nature. Moreover, these data enable the use of M. oligolepis as a model species in biotechnological applications, such as the germ cell transplantation approach.

RESUMO

Background: Currently, there are no regulatory guidelines indicating spacer devices/valved holding chamber (VHC) should be used routinely during pulmonary function tests, and few studies evaluated if spacer devices reduce beta-agonist bronchodilators' side effects. Methods: A prospective study compared salbutamol's cardiovascular effects and bronchodilation response during spirometry tests with and without a spacer device/VHC. Heart rate (HR), the corrected QT interval (QTc), and systolic and diastolic blood pressure were measured 10 minutes after the first spirometry test, before the drug administration, and 20 minutes after inhalation in both groups. Spirometric parameters (forced expiratory volume in the first second [FEV1], forced vital capacity [FVC], and FEV1/FVC) were also measured for both groups. Results: HR and QTc increase were significantly higher in the pressurized meter dose inhalers alone group versus the VHC group [mean SD] [73.1 ± 10 bpm to 74.3 + 10 bpm, p = 0.021] and [median (25%-75% interquartile range)] [389 ms (381-404) to 398 ms (387-407), p = 0.045] vs. [mean SD] [75.4 ± 9 to 73.8 + 8 bpm, p = 0.4] and [median (25%-75% interquartile range)] [388 ms (347-408) to 385 ms (366-408), p = 0.35], respectively. FEV1 variation before and after salbutamol were similar between both groups. Discussion: Although VHC significantly reduces HR and QTc variation when using beta-agonist bronchodilators in healthy patients, no clinical repercussions of this variation were found in this study, since no event of tachycardia or pathological QTc was recorded. Conclusion: VHC has a diminished clinical impact for healthy patients when considering cardiovascular effects and spirometric parameters. Beta-agonist bronchodilators may be administrated despite the use of spacer devices in patients without known cardiovascular diseases. Its significance for other populations still needs to be determined.

RESUMO

Chrysin (5,7-dihydroxyflavone), a nutraceutical flavonoid present in diverse plants, has a backbone structure shared with the flavone backbone, with additional hydroxyl groups that confers its antioxidant properties and effects at the GABAA receptor complex. However, whether these effects are due to the hydroxyl groups is unknown. Here we report the effects of chrysin or the flavone backbone (1 mg/kg) in rats subjected to the elevated plus-maze and the locomotor activity test, as well as in the zebrafish evaluated in light/dark model. Chrysin, but not flavone, increased entries and time in the open arms of the elevated plus-maze, as well as time on white compartment of the light/dark model in zebrafish. These effects were comparable to diazepam, and were devoid of motor effects in both tests, as well as in the locomotor activity test. On the other hand, flavone decreased risk assessment in the light/dark test but increased rearing in the locomotor activity test in rats, suggesting effects threat information gathering; important species differences suggest new avenues of research. It is suggested that the specific effects of chrysin in relation to flavone include more of a mechanism of action in which in addition to its action at the GABAA/benzodiazepine receptor complex also could be involved its free radical scavenging abilities, which require specific research.

RESUMO

The seminal characteristics of Moenkhausia oligolepis are described. Three males were induced with a single dose of carp pituitary. Semen was collected 6 h after induction, and diluted in dibasic sodium phosphate extender solution. For motility analysis, 1 µl of diluted semen was added to 10 µl of distilled water to achieve gamete activation. The average duration of total motility was 76.67 s; while the average sperm motility rate at intervals of 15 s was 95.3, 85.3, 59.6, 31.7, 13.0, 4.6 and 1.2%. To determine sperm concentration in samples, 0.5 µl of semen was diluted with 500 µl of glutaraldehyde. An aliquot of 10 µl of this dilution was utilized for cell counting. An average count of 4.97 × 109 ± 3.46 sperm/ml was obtained. Morphological analyses were performed using eosin-nigrosine dye; 20.33% of the sperm were observed to be dead. Live sperm, comprising the other 79.67%, had an average length of approximately 30 µm, with a head diameter of 4.488 ± 0.7 µm; and a flagella plus mid-piece length of 26.071 ± 12.4 µm. Of those sperm, 69% had a normal morphology, while 31% had primary and secondary abnormalities. The observed abnormality rate did not have a detrimental effect on artificial fertilization potential for the species. The description of the seminal characteristics of a species is one of the most important sets of information required for artificial reproduction of fish in captivity. It also contributes significantly to the total biological knowledge of the studied species.

RESUMO

Nitric oxide has been implicated in symptoms of ethanol withdrawal in animal models. Zebrafish have been used as models to study neurobehavioral effects of ethanol (EtOH) withdrawal, but the mechanisms associated with these effects are not yet clear. Adult zebrafish were treated with 1% EtOH for 20 min per day for 8 days, injected with the nitric oxide synthase 2 (NOS-2) inhibitor aminoguanidine (50 mg/kg), and allowed to experience withdrawal (WD) in their hometanks for 7 days. EtOH WD increased anxiety-like behavior in the novel tank test, an effect that was blocked by aminoguanidine. EtOH WD also increased brain levels of nitrite, an effect that was partially blocked by aminoguanidine. These results underline a novel mechanism by which NOS-2 controls anxiety-like responses to ethanol withdrawal, with implications for the mechanistic study of symptoms associated with chronic ethanol abuse.

RESUMO

Abstract Introduction In rats, long-term ovariectomy results in low concentrations of steroid hormones and reproduces anxiety- and depression-like behavior after surgical menopause in women. Progesterone produces antidepressant-like effects two weeks post-ovariectomy (i.e., early post-ovariectomy) through actions on γ-aminobutyric acid-A (GABAA) receptors, but its antidepressant-like effects and mechanism of action in rats eight weeks post-ovariectomy (i.e., late post-ovariectomy, considered a model of surgical menopause) remain unknown. Objective To explore the antidepressant-like effects of progesterone and the participation of GABAA receptors in rats eight weeks post-ovariectomy. Method Long-term ovariectomized female Wistar rats were treated sub-acutely with vehicle or progesterone (.5, 1, and 2 mg/kg) and subjected to the open field and forced swim tests, and behavior was compared with cycling or fluoxetine-treated rats. The rats were then pretreated with picrotoxin (1 mg/kg) followed by progesterone (1 mg/kg) to explore the role of GABAA receptors in long-term-induced depression-like behavior. Results Long-term ovariectomized rats exhibited depression-like behavior in the forced swim test compared with intact rats, an effect that was not observed in progesterone- and fluoxetine-treated long-term ovariectomized rats. These effects were not attributable to psychomotor alterations. In the open field test, the time spent rearing and grooming was lower in ovariectomized rats compared with intact rats, which was not observed in progesterone- and fluoxetine-treated rats. Picrotoxin blocked the effects of progesterone in both behavioral tests. Discussion and conclusion These results indicated that sub-acute progesterone treatment reduced depression-like behavior through actions on GABAA receptors in a rat model of surgical menopause.

Resumen Introducción En la rata, la ovariectomía a largo plazo reproduce algunos síntomas de la menopausia quirúrgica, incluyendo la conducta de tipo depresiva. La progesterona produce efectos tipo antidepresivo en ratas con dos semanas de post-ovariectomía (post-ovariectomía temprana) con participación del receptor GABAA, pero se desconoce si este efecto y mecanismo de acción se mantiene en ratas con ocho semanas de post-ovariectomía (post-ovariectomía tardía considerada como un modelo de menopausia quirúrgica). Objetivo Evaluar el efecto tipo antidepresivo de la progesterona y la participación del receptor GABAA en ratas con ocho semanas de post-ovariectomía. Método Ratas con ocho semanas de post-ovariectomía fueron tratadas sub-agudamente con vehículo o progesterona (.5, 1, y 2 mg/kg) y comparadas con ratas intactas u ovariectomizadas tratadas con fluoxetina, evaluadas en campo abierto y nado forzado. Posteriormente, se identificó la participación del receptor GABAA en los efectos de progesterona (1 mg/kg) mediante el pretratamiento con picrotoxina (1 mg/kg). Resultados En nado forzado, la ovariectomía produjo conductas tipo depresión en comparación con las ratas intactas de la gónada, un efecto prevenido por la administración de progesterona y fluoxetina. En campo abierto, no hubo cambios significativos en la locomoción, pero la conducta vertical y el acicalamiento fueron bajos en las ratas ovariectomizadas respecto a las ratas intactas; lo cual fue prevenido por progesterona y fluoxetina. La picrotoxina bloqueó los efectos de la progesterona en ambas pruebas conductuales. Discusión y conclusión El tratamiento subagudo con progesterona reduce la conducta tipo depresión inducida en un modelo de menopausia quirúrgica con participación del receptor GABAA.

RESUMO

Strongyloides venezuelensis is a model to study human strongyloidiasis, which infects wild rodents and shares common antigenic epitopes with Strongyloides stercoralis. This study aimed to evaluate parasitological and immunological parameters of prednisolone immunosuppression protocols in rats (Rattus novergicus) infected with S. venezuelensis. Rats were divided into six groups (n = 36): untreated and uninfected (-) or infected (+); oral treatment and uninfected (o-) or infected (o+); subcutaneous treatment and uninfected (sc-) or infected (sc+). For oral immunosuppression, 5 mg/mL of water diluted prednisolone were given five days before infection, and in the days 8 and 21 (for 5 days). For subcutaneous immunosuppression, 10 mg/kg of prednisolone were given daily. The infection was established by the subcutaneous injection of approximately 3,000 S. venezuelensis filarioid larvae per animal. All animals from the (+) and (o+) groups survived, while four rats from the (sc+) died prior to necropsy date. Parasitological analysis showed higher egg elimination in (o+) in comparison to (+) and (sc+) on 7, 13 and 26 days post infection (d.p.i.).The recovery of parasitic females at day 30 was significantly higher in (o+), compared to (+). The (+) and (o+) groups showed a clear increase in anti-S. venezuelensis IgG, IgG1 and IgG2 from 13th d.p.i. Oral immunosuppression led to a higher number of adult females and increased egg output while maintaining IgG and subclasses antibody levels comparable to the positive control.

RESUMO

Chronic alcohol use induces adaptations and toxicity that can induce symptoms of anxiety, autonomic hyperarousal, and epileptic seizures when alcohol is removed (withdrawal syndrome). Zebrafish has recently gained wide attention as a behavioral model to study the neurobehavioral effects of acute and chronic alcohol use, including withdrawal. The literature, however, is very contradictory on findings regarding withdrawal effects, with some studies reporting increased anxiety, while others report no effect. A meta-analytic approach was taken to find the sources of this heterogeneity, and ethanol concentration during exposure and exposure duration were found to be the main sources of variation. A conceptual replication was also made using continuous exposure for 16 days in waterborne ethanol (0.5%) and assessing anxiety-like behavior in the light/dark test after 60 min withdrawal. Withdrawal was shown to reduce preference for darkness, consistent with decreased anxiety, but to increase risk assessment, consistent with increased anxiety. Animals were also subjected to the withdrawal protocol and injected with pilocarpine in a sub-convulsive dose to assess susceptibility to epileptic seizure-like behavior. The protocol was sufficient to increase susceptibility to epileptic seizure-like behavior in animals exposed to ethanol. Finally, withdrawal also decreased catalase activity in the brain, but not in the head kidney, suggesting mechanisms associated with the behavioral effects of ethanol withdrawal.

RESUMO

Background: Dermatosparaxis is an autosomal recessive genetic disease that affects the connective tissue of animals. Collagen proteins form fibrillar structures that provide strength and structure to the extracellular matrix of tissues and organs in the body. Therefore, changes in collagen synthesis result in hyperextensibility and skin fragility. Similar to dermatosparaxis in animals, some cases of Ehlers-Danlos syndrome type VIIC have been reported in humans. The objective of this study was to describe the clinical, anatomopathological, and molecular findings of a case of dermatosparaxis in a sheep bred by crossing the Santa Inês and White Dorper breeds. Case: A case of dermatosparaxis was reported in a 20-day-old female sheep, a cross between the Santa Inês and White Dorper breeds. The sheep exhibited hyperextensibility of the skin with minimal tension and increased joint volume shortly after birth. Because of clinical worsening and the poor prognosis of the disease, the owners opted for euthanasia. The necropsy revealed large ulcerated areas in several parts of the body, including the cervical, sternal, scapular, and thoracic regions, and the inner and outer thighs. The skin was extremely easy to be removed during the necropsy and the use of a scalpel was not necessary. Extensive areas of hemorrhage were observed in the subcutaneous tissue and small intestine. The histopathological findings of the skin lesions evidenced the presence of dermatosparaxis, particularly regarding the disorganization of collagen fibers. The tests involving Masson’s trichrome staining, picrosirius red staining, and Gomori’s trichrome staining under polarized light evidence of collagen fiber dysplasia.Discussion: The diagnosis of dermatosparaxis in this study was based on clinical, anatomopathological, and molecular analysis. Molecular diagnosis was confirmed by identification of SNP c.421G>T on the ADAMTS2 gene in both the mother and the sheep under study...

RESUMO

Os retalhos de padrão axial têm como característica significativa vascularização intrínseca, considerada uma vantagemsobre outras técnicas. Considerando que complicações isquêmicas podem afetar os retalhos cutâneos, técnicas desalvamento são descritas, dentre estas, a terapia por ondas de choque extracorpóreas (TOCE), descrita como capazde modular a vascularização e cicatrização dos retalhos. O presente estudo avaliou histológica e morfometricamente21 amostras de pele; destas, 14 foram submetidas à confecção do retalho axial, sendo sete tratadas também pelaTOCE, obtidas da região distal do retalho axial oris angularis, utilizado para a reconstrução de defeitos palpebraisexperimentais extensos em cães. Foram avaliadas também sete amostras de pele normal da mesma região acimadescrita (grupo controle). Não foram evidenciadas diferenças histológicas significativas no infiltrado inflamatório eatrofia epidérmica microscopicamente. Na análise morfométrica, o número de vasos, a área vascular total e a área médiaforam semelhantes entre os grupos experimentais. O retalho oris angularis associado ou não à TOCE não apresentoucaracterísticas microscópicas de complicações inflamatórias e atróficas significativas. Sinais de integridade tecidual evascularização sanguínea adequados foram observados em ambos os grupos tratados, demonstrando efetividade doretalho oris angularis. A aplicação da TOCE no retalho oris angularis, em dose única de 2500 impulsos a 0,15 mJ/mm2no pós-operatório imediato, não promoveu efeitos colaterais deletérios.(AU)

Considering that the cutaneous flap can be affected by isquemic complications the extra corporeal shock wavetherapy (ESWT) was described as rescue techniques. The present study was developed to analyze histological andwith morfometry, twenty one skin samples treated or not with the shock wave therapy, obtained from flaps distalborder, used in this study to repair eyelids experimental defects in dogs. The flap with or without ESWT did notshow any histological sign of inflammatory or atrophic alterations. Both group treated showed similar morphometricalcharacteristics. The ESWT with the protocol used in this study (2500 impulses at 0,15 mJ/mm2) did not demonstratesignificant clinical outcomes as a rescue technique when applied over the oris angularis flap, however results showed nosignals of collateral deleterious effects.(AU)
