1. Vaginal Distention Rodent Model for Fecal Incontinence: A Pilot Study on the Effect on Defecation Behavior
Abstract Objectives Vaginal balloon inflation simulates the compressive forces on the pelvic floor during the second phase of natural delivery. The foremost use of this animal model of vaginal distention (VD) is to study the mechanisms underlying urinary incontinence. As damage to the pelvic floor during natural birth is a common cause of fecal incontinence

2. Astaxanthin protects against hearing impairment in diabetic rats
Abstract Objectives: Diabetes Mellitus (DM) causes an increase in oxidative stress that leads to deterioration in auditory functions. Astaxanthine (AST) is known to have strong antioxidant effects. In this study, the aim is to investigate the effect of AST against hearing loss that is due to DM. Methods: This study is an experimental animal study. The stud

3. Evaluation of cerebral hemodynamics by transcranial Doppler ultrasonography and its correlation with intracranial pressure in an animal model of intracranial hypertension
RESUMO Antecedentes: O Doppler transcraniano (DTC) é uma técnica não invasiva para a avaliação da hemodinâmica cerebral, porém existem controvérsias na literatura sobre sua aplicabilidade preditiva em situações de elevada pressão intracraniana (PIC). Objetivo: Investigar o fluxo sanguíneo cerebral pelo DTC e correlacioná-lo com as variaçõe

4. Mongolian Gerbils as a Model for the Study of Cholesteatoma: Otoendoscopic as a Diagnostic Tool
Abstract Introduction Cholesteatoma is a disease with significant clinical impact but is incompletely understood. The challenge of performing studies with long-term follow-up in humans is a factor that has restricted the advance of knowledge in this field. Thus, the use of animal models is highly pertinent, and the Mongolian gerbil model has emerged as one

5. Effects of nigella sativa oil on allergic rhinitis: an experimental animal study
Abstract Objectives: Nigella sativa oil is known antiallergic and immunomodulatory effects. We aimed to compare this oil with mometasone furoate, a topical steroid, on a rat model in the prevention of allergic rhinitis symptoms. Methods: A total of 28 two-to-four-month-old Wistar Hannover rats weighing 250–350 g were randomly divided into four groups of

6. Cochlear implantation in an animal model documents cochlear damage at the tip of the implant
Resumo Introdução: A eletrococleografia surgiu recentemente como uma ferramenta diagnóstica na cirurgia de implante coclear, objetiva a preservação da audição e o posicionamento ideal dos eletrodos. Objetivo: Determinar as alterações eletrofisiológicas indicativas de trauma coclear após a cocleostomia e após o implante do eletrodo em diferentes

7. Morphological and pathological changes of Eustachian tube mucosa in an animal model of eosinophilic otitis media
Resumo Introdução A otite média eosinofílica é uma doença relativamente comum de orelha média; entretanto, sua patogênese é ainda obscura, assim como o tratamento. Objetivo Observar as alterações histopatológicas e ultraestruturais do epitélio da mucosa da tuba auditiva em ratos com otite média eosinofílica e investigar a sua patogênese. M

8. FUZZY LOGIC MODELING OF THE OCULAR TEMPERATURE OF CATTLE IN THERMAL STRESS CONDITIONS
ABSTRACT This study proposes a fuzzy logic model capable of predicting the ocular temperature (OT) of beef cattle by means of infrared thermography. The goal of this study is to establish a methodology for making decisions related to animal welfare. The experiment was carried out at a commercial beef production farm, located in the south of Minas Gerais stat

9. AN AUTOMATIC DETECTION METHOD FOR ABNORMAL LAYING HEN ACTIVITIES USING A 3D DEPTH CAMERA
ABSTRACT With the increasing scale of farms and the correspondingly higher number of laying hens, it is increasingly difficult for farmers to monitor their animals in a traditional way. Early warning of abnormal animal activities is helpful for farmers’ fast response to the negative impact on animal health, animal welfare and daily management. This study i

10. NEURO-FUZZY MODELING OF EYEBALL AND CREST TEMPERATURES IN EGG-LAYING HENS
ABSTRACT Considering the challenges faced by poultry farming, this study aimed to develop a neuro-fuzzy model to predict eyeball and crest temperatures of egg-laying hens based on environmental conditions (dry bulb temperature and relative humidity). To develop the models and simulations, Matlab’s Fuzzy Toolbox® (Anfisedit) was used. Different configurati

11. Anatomical background of ovine kidney for use as animal model: analysis of arterial segmentation, proportional volume of each segment and arterial injury after cranial pole partial nephrectomy
ABSTRACT Objective To study the arterial segments of ovine kidney, present a proportional volume analysis of each kidney arterial segment, and analyze arterial injuries caused by simulated partial nephrectomy of cranial pole. Materials and Methods Forty-eight ovine kidneys injected with polyester resin into the renal arteries and collecting system were u

12. Behavior of a Model for Feedback-Controlled Reverberating Circuit and Immediate Memory Function
RESUMO Neste trabalho, implementamos um modelo matemático de transmissão sináptica conectando neurônios em um circuito de descargas reverberantes, a fim de investigar seu comportamento diante de variações paramétricas. Usando um programa desenvolvido em linguagem C, verificamos se o modelo se comportaria como um circuito de memória de curto prazo. Na
