ABSTRACT Consumers are increasingly demanding meat products that are natural and synthetic additive-free. This study aimed to develop a fresh pork sausage without synthetic additives and to evaluate the effects of this formulation on its physicochemical, microbiological, and sensory characteristics throughout its shelf life. Six formulations were prepared: FC = control formulation; F1 = celery extract (0.7 %) and rosemary extract with curry (0.06 %); F2 = celery extract (1 %) and rosemary extract with curry (0.06 %); F3 = celery extract (0.7 %) and rosemary extract with curry (0.1 %); F4 = celery extract (1 %) and rosemary extract with curry (0.1 %); F5 = celery extract (0.85 %) and rosemary extract with curry (0.08 %). The formulations with plant extracts exhibited a lower (p < 0.05) sodium content, and no differences (p > 0.05) were observed in the levels of lipid oxidation compared to FC. No direct relation was observed between the concentration of added celery extract and the residual nitrite content. Fresh sausage with plant extracts demonstrated a microbiological pattern like the control formulation during storage. The sensory acceptance of the formulations with plant extracts was similar to that of FC. The fresh sausages containing plant extracts showed characteristics like those of the conventional product, with these similarities becoming more pronounced throughout storage. additivefree. additivefree additive free. free additive-free physicochemical life prepared F 0.7 07 0 7 (0. % 0.06 006 06 (0.0 1 ( 0.1 01 0.85 085 85 (0.8 0.08 008 08 %. . p 0.05 005 05 content storage product 0.

ABSTRACT Autism Spectrum Disorder (ASD) is a complex neurological condition that can make it difficult to identify symptoms such as pain and neurological changes due to communication limitations. This article reports a case of a 21-year-old autistic patient with cervical disc herniation, treated with posterior endoscopic discectomy. The diagnosis was challenging due to the patient’s inability to clearly express his symptoms, leading to episodes of self-harm. After conservative treatment failed, the endoscopic discectomy was successfully performed using a personalized hospital protocol to minimize the patient’s stress. The procedure was successful, significantly improving quality of life and pain control. This case highlights the importance of considering orthopedic conditions in patients with ASD. It demonstrates the effectiveness of endoscopic discectomy as a minimally invasive option for treating cervical disc herniation in patients with neurological conditions.

RESUMEN El Trastorno del Espectro Autista (TEA) es una condición neurológica compleja que puede dificultar la identificación de síntomas como dolor y cambios neurológicos debido a las limitaciones en la comunicación. Este artículo reporta el caso de un paciente autista de 21 años con hernia discal cervical, tratado con discectomía endoscópica posterior. El diagnóstico fue desafiante debido a la incapacidad del paciente para expresar claramente sus síntomas, lo que llevó a episodios de autoagresión. Tras el fracaso del tratamiento conservador, se realizó con éxito la discectomía endoscópica utilizando un protocolo hospitalario personalizado para minimizar el estrés del paciente. El procedimiento fue exitoso, resultando en una mejora significativa en la calidad de vida y el control del dolor.

Resumo O presente estudo teve como objetivo comparar por grupo etário, sexo, nível competitivo, posição de jogo e anos de prática de futebol dos futebolistas moçambicanos em função das orientações cognitivas para o ego e tarefa. A amostra foi constituída por 443 praticantes de futebol pertencentes a 32 clubes, sendo 196 (44.2%) femininos e 247 (55.8%) masculinos, com idades compreendidas entre os 16 e os 37 anos. Para a realização do estudo foi aplicada a versão traduzida e validada para a língua portuguesa do Task and Ego Orientation in Sport Questionnaire - TEOSQ. Os resultados evidenciam que os futebolistas obtiveram valores altos quanto à orientação cognitiva para a tarefa (4.01 ± 1.07) e moderadamente baixos quanto à orientação para o ego (2.72 ± 1.17). Face aos resultados, conclui-se que o tipo da orientação cognitiva da prática desportiva é um factor importante que distingue os futebolistas moçambicanos. Há predominância de uma orientação cognitiva voltada para a tarefa nestes futebolistas, favorecendo a uma maior manifestação de atitudes desportivas indo de acordo com as evidências literárias em outros contextos de futebol.

Abstract The present study aimed to compare by age group, sex, competitive level, game position, and years of soccer practice of Mozambican soccer players as a function of cognitive orientations for the ego and task. The sample consisted of 443 soccer players from 32 clubs, 196 (44.2%) female and 247 (55.8%) male, aged between 16 and 37 years. To carry out the study, the version translated and validated into Portuguese of the Task and Ego Orientation in Sport Questionnaire - TEOSQ was applied. The results show that soccer players obtained high values for cognitive task orientation (4.01 ± 1.07) and moderately low values for ego orientation (2.72 ± 1.17). Given the results, it is concluded that the type of cognitive orientation of sports practice is an important factor that distinguishes Mozambican footballers. There is a predominance of a task-oriented cognitive orientation in these footballers, favoring a greater manifestation of sporting attitudes following the literary evidence in other football contexts.

Abstract This study aimed to investigate the effect of a short glutamate supply on the ovarian response in goats with low body condition scores. Twenty-one goats had their estrus and follicular waves synchronized using three injections of prostaglandin analog at seven-day intervals. Goats were allocated to groups receiving 10 mg/kg LW (iv) of glutamate administered in a single dose (group LBCG1, n = 7) or in two doses five days apart (group LBCG2, n = 7). The control group (LBC; n = 7) received saline solution. Glutamate treatment did not affect glucose, cholesterol, or glutathione peroxidase levels, body weight, or adipose deposits. During the experimental period, the LBCG2 group showed a higher (P < 0.05) number of follicles (> 3 mm) and an increase in follicle diameter (P < 0.05). Glutamate supply improved (P < 0.05) the intraovarian Doppler blood area size in the LBCG groups, and the second dose in LBCG2 also induced a higher (P < 0.05) systolic and diastolic peak of the ovary artery. After ovulation induction, LBCG2 exhibited a high (P < 0.05) volume of the corpus luteum and vascularized area. We concluded that the supply of two doses of glutamate five days apart was efficient in ovarian stimulation in goats with a low body condition. scores Twentyone Twenty one sevenday seven day intervals 1 mgkg mg kg iv (iv LBCG1 7 7. .

Abstract This study aimed to verify the impact of high-fat diet consumption for a prolonged period on oxidative stress, fetal growth, umbilical vascular system, and placental structures in pregnant goats. Twenty-two pregnant goats were grouped into the control diet (n= 11) and fat diet (n = 11). Flaxseed meal was added to the fat diet, replacing the corn grain of concentrate, from gestational day 100 to delivery date. Diets were isonitrogenous and isoenergetic, differing in fat content (2.8% vs. 6.3% dry matter). The fat group showed higher feed intake and total plasma lipid levels than the control group (P < 0.001). No difference was found in placentome, and umbilical vascular development. Fat diet-fed goats exhibited a lower systolic peak in the umbilical artery. At delivery, placental traits were similar with the exception of the cotyledon width (P = 0.0075), which was smaller in the fat group and cotyledon surface (P = 0.0047) for multiple pregnancy of fat diet. Cotyledonary epithelium showed more intense staining of lipid droplets and a greater area for lipofuscin staining in the fat group compared to control group (P < 0.001). The mean live weight of the kids was lower in the fat group in the first week after delivery than in control group. Thus, in goats, the continuous administration of a high-fat diet during pregnancy does not appear to modify the fetal-maternal vascular structures but has an impact on a part of the placental structure; therefore, its use must be carefully evaluated. highfat high stress growth system Twentytwo Twenty two n= n 11 11. . concentrate 10 date isoenergetic 2.8% 28 2 8 (2.8 vs 63 6 3 6.3 matter. matter matter) P 0.001. 0001 0.001 0 001 0.001) placentome development dietfed fed artery 0.0075, 00075 0.0075 , 0075 0.0075) 0.0047 00047 0047 Thus fetalmaternal maternal structure therefore evaluated 1 2.8 (2. 6. 000 0.00 00 0007 0.007 007 0.004 0004 004 2.

Abstract This study aimed to investigate the reproductive effects of adding monosodium glutamate (MSG) to the diet of goats. Eleven adult goats received synchronized estrus and follicular waves using three prostaglandin analog injections every seven days. Goats allocated to individual pens received 1 g/kg BW of MSG in their diet for 23 days (MOGLU group, n = 6), whereas the control group (n = 5) maintained the base diet. The supplemented animals showed an increase in dry matter intake (P < 0.0001) and a reduction in heart rate (P < 0.05), respiratory rate, and ruminal movement (P < 0.001). Surface and rectal temperatures were higher in the MOGLU group, (P < 0.0001) with a significant increase in the afternoon. There was an increase (P < 0.05) in the frequency of behaviors related to rumination, defecation, and urination in the MOGLU group, and a reduction in behaviors associated with stress (P < 0.05). No differences were observed in the plasma levels of proteins, albumin, urea, cholesterol, or triglycerides. Glucose levels were lower (P < 0.05) in the MOGLU group, which also showed increased glutathione peroxide levels during the induction of ovulation. Supplemented animals recorded a larger number (P < 0.05) of follicles throughout the experimental period and higher intraovarian blood perfusion (P < 0.05) during ovulation induction. We conclude that MSG exerts a positive effect on the reproductive response in goats and therefore represents an effective nutritional supplement.

Abstract Introduction: People infected with the human immunodeficiency virus (HIV) - People living with HIV/AIDS (PLWHA) - seem to have an increased risk of incidence and prevalence of cardiovascular diseases, namely stroke of ischemic nature. Additional etiological mechanisms, in addition to aging, appear to lie in chronic virus-mediated inflammation as well as in antiretroviral therapy (ART). The aim of this study was to carry out a retrospective review with descriptive analysis of cases of PLWHA and with a diagnosis of carotid atherosclerotic disease in a tertiary referral center as well as a non-systematic review of the literature. Methods: All patients diagnosed with HIV infection and concomitantly diagnosed with carotid atherosclerotic disease, in a tertiary center, between October 2007 and December 2019, were selected. A descriptive analysis of the sample and additionally a non-systematic review of the literature using the MEDLINE database, were performed. Results: Nine patients who met the inclusion criteria were selected, 7 (78%) being male. The mean age at diagnosis of carotid disease was 59 years. The diagnosis of HIV infection preceded, on average, 12 years before the diagnosis of carotid disease, while the start of ART preceded this diagnosis by about 11 years. The most common cardiovascular risk factors are dyslipidemia (89%), high blood pressure (56%) and smoking (56%). Approximately 33% had peripheral arterial disease and 22% had coronary artery disease. Only two (22%) patients underwent carotid endarterectomy over a median follow-up of 5 years, both for asymptomatic stenosis. Since the diagnosis of carotid disease, there have been no major cardiovascular events (stroke or acute myocardial infarction). During follow-up there were two deaths. Conclusion: PLWHA have a high prevalence of multisite artery disease, manifesting it at a relatively earlier age compared to the general population. These patients benefit from multidisciplinary follow-up for therapeutic optimization in order to obtain better results. However, larger prospective studies are needed to clarify the results in these patients and to improve the therapeutic approach, particularly in those with concomitant carotid disease.

Abstract This study examined the effect of glycerin supply strategies in different short-term protocols on follicular dynamics and ovulatory rate in Morada Nova sheep. Eighteen Morada Nova ewes with body condition > 2.9 had their estrus and follicular waves synchronized using three injections of prostaglandin analogue at seven-day intervals. All animals received the same diet during 21 days, which consisted of a total mixed ration (TMR) based on chopped elephant grass and concentrate twice daily. In thecontrol group (n=9), ewes were fed the TMR diet. In the other four groups, ewes received 150 mL of glycerol daily, supplied as an oral drench or mixed in the TMR during three or seven days prior to the application of thethird PGF2 alfa analogue. These groups were named as follows: Drench3d (n=10), Drench7d (n=8), TMR3d (n=9) and TMR7d (n=9). Follicle dynamics were monitored by ultrasonography, and plasma glucose and glutathione peroxidase levels were measured at the third prostaglandin administration. Six days after the final PGF2 alfa analogue dose, ovulatory rate was measured by laparoscopy. Glucose was higher (P< 0.001) in the glycerin-treated groups than in control group (83.7 ± 1.7 vs. 68.4 ± 4.5 mg. dL-1; P < 0.001). Ewes in the TMR3d, Drench7d and TMR7d groups had a greater (P < 0.001) number of large follicles (≥ 3 < 5 mm), and the presence of follicles larger than 5 mm was observed. In the same groups, at the third PGF2 alfa analogue dose, a greater (P < 0.001) number of growing follicles (> 3 mm) and a larger size of the largest follicle (P < 0.001) were also recorded. Ovulation rate was 30% higher in the groups that received glycerin for seven days (1.6 ± 0.1 53 vs. 1.1 ± 0.1; P < 0.05), and they also exhibited a 38% reduction in glutathione peroxidase. Thus,the use of glycerin in Morada Nova sheep as a source of energy in short-term supplementation for increase ovulation rate is an efficient strategy when provided for seven days, either orally or in the feed.

RESUMO Introdução: o tratamento cirúrgico da obesidade acarreta importantes alterações na mecânica respiratória. Objetivo: analisar comparativamente a força muscular respiratória em pacientes submetidos à cirurgia bariátrica do tipo bypass gástrico por laparotomia e por videolaparoscopia durante o internamento cirúrgico. Métodos: estudo observacional com delineamento longitudinal não-randomizado, de caráter quantitativo. Foram coletados dados de 60 pacientes com índice de massa corporal igual ou superior a 40Kg/m2, candidatos a cirurgia bariátrica e divididos em grupo 1, para os operados por laparotomia (n=30), e grupo 2, para os operados por videolaparoscopia (n=30). Foram excluídos os tabagistas, os pacientes incapazes de executar o exame de forma correta e os portadores de doenças pulmonares prévias. Ambos os grupos foram avaliados no pré-operatório imediato, no primeiro e no segundo dias de pós-operatório através do teste de manovacuometria para a força muscular respiratória e da escala visual analógica de dor. Resultados: a amostra foi homogênea em relação à idade, índice de massa corporal e sexo. Foi observado redução das pressões respiratórias máximas após a cirurgia para os operados por laparotomia, sem retorno aos valores basais no dia da alta hospitalar no segundo dia pósoperatório. Esse grupo também cursou com dor mais intensa e maior tempo cirúrgico. Não houve diferença das medidas de pressão respiratória após a cirurgia no grupo operado por laparoscopia. Conclusões: a cirurgia bariátrica pela via convencional reduz a força muscular respiratória no pós-operatório e cursa com dor mais intensa durante a internação cirúrgica em relação à via laparoscópica.

ABSTRACT Introduction: surgical treatment of obesity causes important changes in respiratory mechanics. Aim: Comparatively analyze respiratory muscle strength in post bariatric patients underwent to gastric bypass by laparotomy and laparoscopy during hospital stay. Methods: observational study with a non-randomized longitudinal design, of a quantitative character. Data were collected from 60 patients with BMI 40Kg/m2, divided in laparotomy group (n=30) and laparoscopy group (n=30). Smokers, patients with previous lung diseases and those unable to perform the exam correctly were excluded. Both groups were evaluated at immediate postoperative, first and second postoperative days with manovacuometry for respiratory muscle strength and visual analogue pain scale. Results: the sample was homogeneous in age, sex and BMI. Reduction in maximal respiratory pressures was observed after surgery for those operated on by laparotomy, no return to baseline values on discharge day on the second postoperative day. This group had also more severe pain and longer operative time. There was no difference in respiratory pressure measurements after surgery in the laparoscopy group. Conclusion: conventional bariatric surgery reduces muscle strength in the postoperative period and leads to more intense pain during hospitalization when compared to the laparoscopy group.

Resumo As ciências humanas são importantes para o entendimento da sociedade, mais a ciência geográfica tem sido uma das principais pontes para estudos nas relações do homem e natureza, incorporados diante das categorias, espaço, lugar, território, paisagem e região. Neste ensaio teórico buscou-se compreender a evolução conceitual do tema e entender como a categoria de espaço constrói a identidade. Pensou-se no objetivo geral; refletir sobre espaço como uma categoria da base epistemológica geográfica para a construção de identidade. Além disso, recorreu-se, de forma a alguns das principais contribuições teóricas clássicas, (Eric Dardel, Alfredo Wagner Berno de Almeida, Ana fani Alessandri Carlos, Stuart Hall, Henry Lefebvre, Karl Marx, Milton Santos) com intuito de compreender a evolução dos conceitos de espaço para construção da identidade.

Abstract The human sciences are important for the understanding of society, but science geography has been one of the main bridges for studies on the relations of man and nature, incorporated in the face of the categories, space, place, territory, landscape and region. In this theoretical essay, we sought to understand the conceptual evolution of the theme and understand how the category of space builds identity. The general objective was thought; reflect on space as a category of the geographic epistemological basis for the construction of identity. In addition, some of the main classical theoretical contributions (Eric Dardel, Alfredo Wagner Berno de Almeida, Ana fani Alessandri Carlos, Stuart Hall, Henry Lefebvre, Karl Marx, Milton Santos) were used in order to understand evolution of the concepts of space for the construction of identity.

Además, se utilizaron algunas de las principales aportaciones teóricas clásicas (Eric Dardel, Alfredo Wagner Berno de Almeida, Ana fani Alessandri Carlos, Stuart Hall, Henry Lefebvre, Karl Marx, Milton Santos) para comprender la evolución de los conceptos de espacio. para la construcción de la identidad.

RESUMO Este estudo avaliou as propriedades físico-químicas envolvidas no processo de adsorção para subsidiar o potencial uso de biocarvão produzido com folhas secas de amendoeira-da-praia, Terminalia catappa, como remediador em águas contaminadas com metais. O biocarvão utilizado foi produzido por conversão à baixa temperatura e caracterizado por apresentar bandas de O-H, CH2, C-O e C-O-C; teores de 48,8% de carbono, 46,6% de oxigênio, 3,3% de hidrogênio e demais entre enxofre e nitrogênio; presença de macroporos e passado em peneira (100 mesh). Para o estudo, preparou-se um coquetel de radiotraçadores (Co-57, Mn-54 e Zn-65), que foi adicionado à água deionizada e massas de biocarvão com o objetivo de obter parâmetros tais como pH, tempo de equilíbrio e capacidade de adsorção por meio das isotermas de Langmuir e Freundlich. O detector de Germânio Hiperpuro foi utilizado para quantificar as atividades dos radiotraçadores por meio da técnica de espectroscopia gama para geração e tratamento de dados. Os resultados obtidos mostraram aumento na adsorção do pH 3,8 em diante e tempo de equilíbrio de 30 minutos ou mais. As isotermas de Langmuir e Freundlich construídas apresentaram bons ajustes, com valores de n maiores que 1, indicando preferência dos metais pelo material adsorvente. Além disso, levando-se em conta a competição pelos sítios ativos e a concentração inicial das soluções (ordem de picogramas), foram encontradas capacidades de adsorção de 1,273 ng.g-1 para o Zn-65, de 3.271 ng.g-1 para o Co-57 e de 9,026 ng.g-1 para o Mn-54.

ABSTRACT This study evaluated the physical-chemical properties of the adsorption process in biochar produced from dry leaves of beach-almond, Terminalia catappa, as a useful tool for remediation purposes in water contaminated with metals. The biochar was characterized by having: bands of O-H, CH2, C-O, and C-O-C; contents of 48.8% carbon, 46.6% oxygen, 3.3% hydrogen and the others between sulfur and nitrogen; the presence of macropores; and being sieved (100 mesh). Parameters such as pH, equilibrium time and adsorption capacity by the Langmuir and Freundlich isotherms were determined from experiments using a radiotracer cocktail (Co-57, Mn-54 and Zn-65) which was added to deionized water and a constants mass of biochar. The high-purity germanium detector (HPGe) was used to quantify the radiotracer activity by gamma spectroscopy. The results showed better adsorption from pH 3.8 and 30 minutes equilibrium time. The Langmuir and Freundlich isotherms had a good model fit, with n values higher than 1, and showed affinity between the metals and the biochar. The adsorption capacities of Zn-65, Co-57 and Mn-54 were 1.273 ng.g−1, 3.271 ng.g−1 and 9.026 ng.g−1, respectively.
