Estresse oxidativo, alterações metabólicas e renais decorrentes da elevada ingestão de sacarose: efeito protetor da N-acetilcisteína (NAC)

Oxidative stress is related with physiopathology of diabetes mellitus type II and with its secondary complications, such as diabetic nephropathy. Thus, the purpose of this study was to examine the effects of n-acetylcysteine NAC, an antioxidant from Allium cepa, on oxidative stress, morphometrical and nutritional parameters and basal metabolism and energetic substrate utilization, serum glucose and oral glucose tolerance test (OGTT), and renal function of high-sucrose intake rats. Animals were initially divided into three groups. Rats in the control group (C; n=10) were given free access to a standard chow and water; (S; n=10) group received standard chow and 30% sucrose in its drinking water; (SN; n=5) group received standard chow and 2g/L NAC and 30% sucrose in its drinking water. After 25 days of treatments, rats were submitted to indirect calorimetry in fasted and feed states. After 30 days of treatments, rats from C and S groups were divided into four groups of five rats each. The (CC) and (SS) groups were given an intra-gastric dose 0,6mL saline (0,9%NaCl) and the (CNAC) and (SNAC) groups were treated with a intra-gastric dose of 0,6mL NAC (160g/day), and then everybody received a intra-gastric dose of glucose solution (20%) for the OGTT. Animals of S and SN groups have higher liquid consumption and lower food consumption than C group. Calorimetric analyses confirm that despite of the final body weight had not statistical difference among groups, S group have lower resting metabolic rate when compared to C and SN animals. Besides, S group has higher respiratory quotient, higher carbohydrate oxidation and lower lipid oxidation, both in fasted and feed states, than C and SN groups, evidencing the beneficial effect of NAC. Fasting plasma glucose is increased in SS and SNAC animals when compared to CC and CNAC, however SN group has glicemic level at 30 min before OGTT decreased when ...(Complete abstract click electronic access below)

Doenças metabólicas do periparto em bovinos leiteiros

Peripartum or Transition Period is, generally, defined as the period between three weeks pre-calving and three weeks after calving. It is a critical and crucial stage to the cow’s health and to economic profitability during the lactation. During this phase the cows experience several changes that prepare them to calve and milk yield. These changes contribute to metabolic disorders’ incidence, and can lead to reproductive function and milk yield reduction, and increase the herd’s disposal. This paper aimed to review the peripartum metabolic diseases, which includes Ketosis, Hypocalcemia, Hepatic Steatosis, Ruminal Acidosis and Lameness

O câncer e as alterações no estado nutricional do paciente: importância da atenção farmacêutica

O Câncer é uma doença epidêmica e multifatorial. O uso combinado ou não de cirurgia, radioterapia e quimioterapia formam o alicerce sobre o qual se assentam a quase totalidade dos tratamentos contra os mais variados tipos de câncer. Essas terapêuticas quase sempre são agressivas, o que leva a uma ameaça séria à integridade física, sabidamente associada a problemas nutricionais. Pela legislação RDC nº220, publicada pela Agência Nacional de Vigilância Sanitária (ANVISA) em 21 de setembro de 2004, que regulamenta os estabelecimentos públicos e privados do país que realizam tratamento de quimioterapia antineoplásica, o farmacêutico deve fazer parte da equipe multiprofissional em terapia antineoplásica, como responsável pela manipulação de todos os antineoplásicos. Levando isso em consideração, o trabalho realiza uma descrição geral desde o desenvolvimento da doença, passando pelos principais agentes causadores e destaca a importância da terapia nutricional, principalmente no período pós-tratamento que influencia diretamente na morbi-mortalidade do câncer. Associando conhecimentos interdisciplinares entendemos que o farmacêutico possa exercer além da manipulação de drogas, a atenção farmacêutica contribuindo positivamente na equipe de saúde, visando uma maior adesão ao tratamento além do aumento da qualidade de vida do paciente oncológico. A partir do levantamento bibliográfico apresentado ampliamos a compreensão da complexidade dos mecanismos da doença, a importância da Terapia Nutricional e o Papel que o profissional farmacêutico pode desempenhar nesse campo

Técnicas associadas à biotecnologia da reprodução para minimizar os efeitos do estresse térmico e aumentar a fertilidade em vacas leiteiras de alta produção

The dairy sector has undergone considerable economic losses due to low fertility rates due to adverse effects of heat stress on reproduction of cows. Genetic selection for increased production, coupled with the expanding dairy to tropical areas of the planet, and global warming has further aggravated the problem of heat stress. The effects of heat stress are multifactorial and act directly or indirectly at various levels of reproductive tissues, resulting in low fertility of cows, which in practice, results in reduced reproductive efficiency in the property, reducing the producers’ profit. Some strategies related to breeding biotechnology such as fixed-time artificial insemination, embryo transfer and use of BST, can minimize these effects and improve the reproductive efficiency of the herd

Etiopatogenia e tratamento do deslocamento de abomaso em bovinos leiteiros de alta produção

The dairy business is in constant development, in order to achieve better results and higher profits to the producer, and this search for improvement has led to the selection of a herd more productive. But this has caused some problems heightened, among them the displacement of the abomasum, a disease that affects much of the high producing dairy herd. The main reasons are apparently related to the feeding management, with the abrupt changes that the animal suffers in the post partum period, with diseases that would cause abomasal atony favoring its displacement, among others. When affected, the animals lose their appetite and in milk production, and may even, in severe cases, death to come. Treatments described in literature are varied and there are conservative and chirurgical methods. The choice of a particular technique depends on the financial condition of the producer, the economic value of the cow and from personal experience and technique of the veterinarian. Understanding the clinical implications of displaced abomasum is necessary not only for its animal identification in the field and its appropriate treatment but also for finding the errors and inadequacies in the management system of production that trigger this disease

Deficiência de Cobalto em Ruminantes no Brasil

Cobalt is a essential microelement for the metabolismo of ruminants. Its deficiency leads to decreased levels of vitamin B12 and, consequently, non propionic acid metabolism. Thus, there will be no gliconeogenes and animals have defict glucose, and other tramadol dosing as apathy, alitriofagia, and decrease in production. It is a disease that affects catthe, of economic importance in Brazil, wich is related to the of the soilcomposition

Estresse término na reprodução de vacas leiteiras

Climate change in tropical countries, like Brazil, causes major problems in dairy production due to an increase of heat stress effects. In recent years, milk production in Brazil increased 36.07%. The Southeast region remains a leader in production with herds of high producing Holstein cattle (mostly), which is more susceptible to heat stress. Thermal stress decreases fertility in direct and indirect ways. Conception rates are reduced of 40-60% during cooler months of the year and 10-20% in the warmer months. Negative effects of heat stress involve changes in reproductive hormones, follicular development, oocytes, and embryos, and decreased dry matter intake. Several studies discuss change in reproductive hormones, such as reduction in plasma concentration of GnRH, LH, and oestradiol, which lead to decreased detection of estrus and ovulation. Various methods are being studied to bypass these negative effects and increase the fertility of dairy cows under heat stress. Cooling systems are the most advantageous and can be associated with technologies such as ET and TAI

O uso da chupeta: elaboração de material pedagógico para orientação dos profissionais das escolas de educação infantil

What is the relationship of a pacifier as for nutrition, speech, dental and psychotherapy? What are its benefits and harm? Which strategies should be developed as a teaching material which can guide employees and teachers of early childhood education regarding the use of pacifier in schools?

The booklet was prepared containing topics such as: social and historical aspects; psycho-physiological aspects of development, speech therapy and dental aspects; pros and cons of using a pacifier; teaching materials on the pedagogical use of pacifiers. Tips and information to the teacher

Deslocamento de abomaso em vacas leiteiras

The genetic selection and the nutritional management to improve milk production make the dairy cattle more susceptible to the development of diseases, such as the abomasal displacement. It is the most frequently detected abomasal problem and it is the main cause of abdominal surgeries in dairy cattle. It is a multifactorial disease that occurs mainly in dairy cattle of high production during the puerperium. The abomasal displacement can occur to the right (DAD) or to the left (DAE), being the former more frequent than the latter. It is related to feeding management and occurs in animals that also have other diseases such as hypocalcaemia, ketosis and retained placenta. The disease causes economical losses in dairy cattle because of the costs with treatment, reduction of production, increase of the interval between the parturition, loss of body weight, early discard of the matrix and mortality. The most usual clinical signs are apathy, dehydration, low to serious ruminal timpanismo (gas accumulation in the abomasum) with reduction or lack of motility, liquid splash sound during the ballottement of the right flank, metallic sound to percussion, presence of a structure similar to distended viscera in the thorax or in the paralombar cavity on the side corresponding to the displacement, and liquefied, dark, scarce and fetid feces. The treatment is surgical, and the most used technique is the omentopexy on the left flank. The hidroelectrolytic correction must be performed and the concomitant diseases must be treated. The prophylaxis consists of adequate nutrition and pre-parturition management, besides reduction of stress and other diseases of the puerperium
