Cuidados essenciais ao bezerro neonato nas primeiras 24 horas de vida

The change from the uterine environment to the external environment that occurs afterbirth requires rapid adaptation of the newborn. The right care in the first 24 hours of life can significantly reduce calves’ mortality. In this context, are included essential care to animals that are born weak and require immediate assistance so they can adapt to the extra uterine environment, such as stimulating the onset of spontaneous breathing and thermoregulation. The essential care is also related to colostrum feeding and treatment of the navel. The objective of this work is to bring together some of the major causes of morbidity and mortality in the first 24 hours of life of the newborn calf and discuss some of the special care that these animals require

Puberdade em novilhas

The age which heifers reach puberty depend on factors like genetics, environment and nutrition. Puberty in heifers can be defined as the onset of reproductive competence, the ability to ovulate a fertile oocyte with an estrous behavior and development of a corpus luteum with normal lifespan. The metabolic signals that trigger puberty are not yet fully defined. In Brazil, where most beef cattle are zebu, the age at puberty is very advanced, mainly these animals are feed with a poor diet. Many researches are trying to discover the metabolic signals that trigger puberty and anticipate better economic return in breeding farms. It has been demonstrated that the cascade of endocrine events that culminate in puberty can be hastened by an alternative management scheme that involves increased nutrient intake between 3 and 7 months of life. Different diet concentrations, different products and by-products have been used in research to achieve puberty early (less than 300 days of age). The hormonal induction of puberty, especially with the use of progestagens, has been developed in heifers as an alternative tool to improve reproductive efficiency in herds, increasing the amount of pregnant heifers in breeding season

Agressividade relacionada ao contexto alimentar em escorpião-amarelo Tityus Serrulatus (Lutz & Mello, 1922)(Scorpiones, Buthidae)

Scorpions are among the oldest living groups of animals, and are present in almost every continent. Although many studies are made about the toxins present in their venom, little is known about their behavior. The aim of this paper is to investigate the expression of agressiveness in the brazilian yellow scorpion Tityus serrulatus, specifically the relation between agressiveness, motor activity and feeding condition. The study was divided in two parts. First, we used 16 adult individuals, placed in two terrarium, to establish an ethogram. Each group was observed for 36h, and the behaviors displayed were described and categorized as agonistic or non-agonistic. In the second part of the experiment, we used 32 adult animals in three different nutritional states: Feeding (still ingesting food), Sated (1 to 4 days since last meal) and Deprived (14 to 25 days since last meal). The individuals were paired, each pair placed in a terrarium and observed for 30min. Behaviors displayed were timed in seconds. Our results show that only Feeding individuals displayed agonism towards others, and no relation was observed between motor activity and feeding conditions

Diferentes métodos de diagnóstico molecular na diferenciação das espécies de Sarcocystis spp

The Sarcocystis genus includes obligatory two-host life cycle protozoan parasites. It is the most numerous of the six genera of the Sarcocystidae family. The infection caused by parasites of this genus is a zoonotic and cosmopolitan disease known as sarcosistosis or sarcosporidiosis. The sarcositosis though frequently asymptomatic in its definitive hosts can be fatal in its intermediate hosts. The usual diagnoses of sarcosistosis takes place through a histological demonstration of schizonts in blood vessels and organs, and the presence of cysts in muscle tissue by necropsy or biopsy, this second method still more common and based on morphological features of the sarcocyst. However, these methods can be inadequate to a precise identification of the infector species once that, besides the genus being of numerous species, these often present similar morphological features. Another factor that makes the diagnostic more difficult is the non specificity of some Sacocystis species to their hosts. Consequently, molecular diagnostic methods have been used in order to identify the infector species and the parasite specific biological cycles, demonstrating also new species and coevolutive aspects between parasite and host. Among the most employed molecular techniques the Polimerase Chain Reaction (PCR), the nested-PCR and the Restriction Fragment Length Polymorphism (RFLP) stands out

Estudo de um ciclo de vapor utilizado para tratamento de superificies metálicas: estudo preliminar de caso

The use of heat in parallel with relative low temperatures and applied to several areas of the industry is essential for the main manufacturing processes, like drying, dehydrating, concentration, annealing, production of chemical reactions, and microbiological sterilization. Without neither the heat nor the coming of a great quantity of thermal heat, with high quality, there would not be the “modern society”, with its high standards of living plus its high consumption levels; from services to goods in general. Within an almost absolute way, the heat flows are obtained from vapor systems. Thus, in this work we are going into the operation of a vapor system, composed of two firetube boilers dimensioned to supply vapor for three processes. However, with the transfer of one of the processes to another plant, the system got over-dimensioned. But, taking advantage of this scenario, the two boilers were used to supply vapor to further processes, causing their intermittent usage. Moreover, the operational alternative adopted by the maintenance engineering of the plant for a creating a solution has been presented; both the positive points and negative ones were disclosed, likewise the possibility of improvement points

We will analyzed a trial class in which a physics teacher of a public school Guaratinguetá city interacted with their student, seeking to categorize certain movements of the teacher's speech and identify the moments when this could establish the definition of the situation, mediation semiotic and intersubjectivity

Estudo sobre a necessidade e preferência sobre orientações de enfermagem ao paciente oncológico adulto em quimioterapia

Most cancer types are treated by antineoplastic chemotherapy, which can be performed conjointly with other treatments, such as radiotherapy and surgery. Due to its action, chemotherapy provides the possibility of cure, but it also leads to a number of adverse effects, such as myelosuppression, cutaneous and gastrointestinal toxicity, etc. Patients undergoing chemotherapy must receive constant information concerning how to prevent or minimize these effects in order to achieve better quality of life and, consequently, a more successful treatment. Hence, this study aimed at investigating the need and preference for different forms of information by oncologic patients submitted to chemotherapy. It is a cross-sectional, descriptive and quantitative study conducted at the chemotherapy division of the Botucatu School of Medicine University Hospital/SP on a sample of 50 patients older than 18 years. After previous knowledge of the study and formalization of Free Consent, the individuals answered a questionnaire containing 12 questions related to the importance attributed to the information received, from which professional and when to receive it. Data were analyzed by Fisher’s exact test and showed that 62% of the patients were females, and the remaining 38% were males of whom 46% were older than 60 years, 26% were from 50 to 60 years old, 24% from 30 to 50, and only 4% were younger than 30 years old. The patients had lymphatic (23.4%) and solid (76.6%) tumors. All the respondents reported that receiving information about the disease and its treatment was extremely important. As regards information related to side effects, 98% of patients answered that receiving it was extremely important, and only 2% answered that it was little important. Correlations were made between age, gender, and tumor type with the answers obtained for the best moment, how and from whom to receive such informatio...

Criopreservação de sêmen de epidídimo de garanhões

It is a fact that Brasil has a featured position in the equine market due to the size and the high quality of its squad. To keep the competitivity, the reproduction biotechnologies have a big and important role. The cryopreservation of stallion semen, for example, generates innumerous advantages, which includes: larger number of obtained doses, storing genetic material for undetermined time, using the semen of a good stallion even after its dead or any other event that makes both semen collection and mating impossible, etc. In this context, the cryopreservation of epididymal sperm, has been seen as a promising technique in equine reproduction. The epididymal cauda has a significant quantity of fertile spermatozoa and this ensures a huge store of cells in cases of unexpected accidents, which can early interrupt with the reproductive life of a stallion. Lots of studies are being developed using the cryopreservation of stallion epididymal sperm. These studies permit the propagation of high quality genetic material and make possible for the stallion owner to opt for a final semen collect in unexpected circumstances

Síndromes paraneoplásicas hematológicas em cães

Tumoral masses can cause several direct problems in the organism, such as invading organs and altering their functions, leading to other problems such as the Paraneoplastic syndrome. The paraneoplastic syndrome is an alteration in the structure and function of the body due to the non-invasive actions of the tumor, for example, liberating hormones, peptides, cytokines and leading to cross reactions between normal tissues. The syndrome can affect different locations in the body, being that some are indicative of specific tumors, however the interpretation of the clinical and pathological findings referring to this syndrome should be utilized in the diagnostic and treatment. In the hematological paraneoplastic syndrome, there are alterations that occur due to indirect actions of the tumor on the blood cellular elements and the coagulation system, and that are generally detected in routine clinical and laboratorial exams. This study objective is to aboard some hematological paraneoplastic syndromes in dogs such as: anemia, thrombocytopenia, neutrophilic leukocytosis, hypergammaglobulinemia and erythrocytosis, emphasizing the different etiologies that may assist in differential diagnosis and the principal neoplasm related to this syndrome. Besides this, the early discovery and treatment of the paraneoplatic syndrome is important as the tumor itself, as it improves the prognostic and quality of life of the patient

Etiopatogênia da artrite-encefalite caprina e estratégias para seu controle

The arthritis-encephalitis caprine vírus is found at mostly areas of the world, especially at the countries that milk goats is strongly tecnific, and already was found in many brasilian states. The illness causes greats econimics prejudice, influencing badly the productive life time of the flock, related with the low production, decrease of the reproductive performance and lost of the genetic potential, determining constants flock’s renew. Many authors calls the atention for the probable dissemination of the illness and reinforce the necessity of the adoption strong sanitary politics for the illnes control. The controls programs, basically, based on knowledeg of the target-cells, that keep and distribute the virus on the guests organisms; on the transmition way; on sensibility and specificity of the sorologics tests, as well as your frequency of realitation in the flock; and after all on the management that the flock is submeted

Remoção de matéria orgânica e nitrogênio de efluentes provenientes de abatedouros de bovinos por meio de reator aeróbio operando em bateladas sequenciais com adição de coagulante químico

The volume of liquid effluent generated in cattle slaughterhouses is quite high and cannot be released untreated in water bodies due to its high pollution load of predominantly organic origin. To minimize the environmental impacts of its industrial wastewater and meet the local environmental legislation, abattoirs shall make the treatment of these effluents. The present work aims to develop the study of a reactor by sequential batch pilot scale, in order to optimize their performance in treating wastewater from a cattle slaughterhouse. The treatment system used was developed and installed in the Laboratory of Wastewater Treatment, in Faculty of Science and Technology UNESP, Presidente Prudente campus. The procedure used followed the operation of sequential batch reactors, in which all processes and treatment operations occurring sequentially in a single unit, by establishing specific operating cycles, which comprise the following separated phases: aerobic reaction, anoxic reaction, sedimentation and emptying. Aiming to improve the quality of treatment was planned the addition of coagulant Poly Aluminum Chloride (PAC) in the reactor, by determining their optimal dosage by Jar-test trials. Were prepared four steps with specific operating cycles: step one or acclimatization (10 hour of aeration, one hour and 30 minutes of sedimentation and 30 minutes for exchanging the effluent); step 2 (6 hours of aeration or aerobic phase, 4 hours and 45 minutes of stirring or anoxic phase and 1 hour and 15 minutes for sedimentation and exchange effluent); step 3 (2 hours and 30 minutes of aeration, 8 hours and 15 minutes of stirring and 1 hour and 15 minutes for sedimentation and exchange) and step 4 (2 hours of aeration, 8 hours and 45 minutes of stirring and 1 hour and 15 minutes for sedimentation and exchange)...

Potenciais aves dispersoras de sementes das espécies vegetais zoocóricas da Mata da Bica, Botucatu - SP

The semidecidual forests, as tropical forests, presents zoochoric dispersal syndrome in the most of their plant species, with approximately one third of frugivorous species responsible for the seeds dispersal are birds. The bills width is a limiting factor, it must be equal or bigger than the seeds width, because the viable seeds dispersal depends on leaving the digestive system after been swallowed hole. Birds and plants inventorys were realized in a semidecidual Forest fragment, in Botucatu – SP, called Mata da Bica. After this, the birds consumers of fuits/seeds were selected (frugivorous, granivorous and onivorous) and also the zoochoric plants, both for building a possibilities matrix, to verify the potential seed dispersers according to the seeds and bills width. Going to the matrix end we can observe a decrease in the interaction possibillities, because the seeds width increases and the bills width decreases. It has been observed that 50,7% seeds could be dispersed by all listed birds, because the seeds were narrower than the narrowest bill. In the other way large seeded species, as Holocalix balansae and Hymemaea courbaril has shown only two possible dispersers: Trogon surrucura and Piaya cayana. There are no possible dispersers to Syagrus oleraceae in the matrix. The need for large birds or other animals that works as large seed disperses demand conservation efforts, since most of these animals need big and conserved areas for their life habits

Usos não-padrão das estratégias de relativização no português brasileiro: hipercorreção e estilo

This study focuses on the current use of the relative pronoun qual and variants or alternatives (o/os/a/as/ qual/quais, preceded or not by prepositions) in Brazilian Portuguese concerning mainly on the phenomenon of hypercorrection. As a theoretical basis, it was used the study of William Labov about the phenomenon and also the rules of use of this pronoun present in both traditional grammars and linguistic studies. It was performed a qualitative analysis of a corpus of written language with the intention of describing the different uses of the pronoun, and looking for their possible motivations. There were also found different types of occurrences of hypercorrection, which has led to propose a scale of uses of this relative pronoun, which reveals an increasing loss of its functions towards an use as an index of prestige. It discusses also the stylistic factor as a potential motivator of this phenomenon

Estudo de um caso de tratamento de câncer com um produto alternativo às técnicas convencionais

This work consists of a case study, a qualitative methodology, which aims to show the effects of TIVALLEC, a supplement in vitamins, as an alternative treatment of cancer. This study had also the objective of evaluating one patient’s quality of life thirteen years after being diagnosed with an advanced prostate cancer, and having decided for an alternative treatment using TIVALLEC instead of conventional treatments, having obtained excellent results. An open interview was conducted with patient, evaluating various aspects of his life after the initial diagnosis and the chosen treatment. The answers were transcribed after being limitedly edited for readability. At the end of the study, with the support of recent literature, the interview allowed the conclusion that TIVALLEC was greatly effective, creating good quality of life and wellness for the patient during all the period of thirteen year after the diagnosis up to now. These alternative treatment results may be seen as demanding new studies to help cancer patients who embrace or not the conventional treatments

Análise do conforto térmico da cidade de Mirandópolis/SP em seus espaços abertos

Mirandópolis/SP appeared in 1934 from the railroad “the Brazil Northwest”, that there it served one of the points of its stretch that had as main function to drain the agricultural production northwestern native of São Paulo of that time. The installation of the town happened absent of concerns with initial urbanístico planning, thus modifying its natural landscape and modifying characteristic ambient without compensatory measures aiming at a future expansion of the urban mesh. Fact this that still causes today consequences the quality of life of the people and also the observed thermal comfort later. Ahead of this, the present work had for objective to identify through measurements of temperature and relative humidity of the city of Mirandópolis/SP the differences that in the fabric urban they corroborate for a comfort situation or thermal discomfort to the outdoors in accordance with the Diagram Bioclimático de Olgyay the collection of data was made throughout the month of July of 2011 involving the attainment of information of Temperature and relative humidity of air and questionnaire applied to the passer-bys in the act of the measurements. Also approaching the different thermal dynamic of the zones of housing in relation to the Urban Cannyon that develops the commerce as predominant activity. This research sample that, although a city to be small, the quality of life of its inhabitants is not only guaranteed by the transport or that its thermal comfort reveals inside homogeneous of the urban perimeter, but that it has yes heterogeneidade in the scope of the urban climate in these spaces
