ABSTRACT
Objetivou-se avaliar a viabilidade econômica de vacas F1 de Holandês x Zebu de diferentes bases maternas e ordens de parto. Foram utilizados dados do Campo Experimental da Epamig (Felixlândia-MG). Analisaram-se 406 lactações de vacas F1 H x Z de diferentes bases maternas. Estimaram-se a receita e os custos operacional efetivo, operacional total e custo total. As F1 Holandês x Gir tiveram médias de custos maiores (R$ 3582,30), seguidas pelas F1 Holandês x Nelogir (R$ 3448,06), e o menor foi das F1 Holandês x Nelore (R$ 3145,07). A receita total foi maior para as vacas F1 Holandês x Gir e F1 Holandês x Nelogir, com valores de R$ 4394,96 e R$ 4245,61, respectivamente, e a menor receita foi para F1 Holandês x Nelore, com valor de R$ 3976,12. O lucro foi de R$ 812, 65; R$ 797,54 e R$ 831,04 para as F1 filhas de base materna Gir, Nelogir e Nelore, respectivamente. Todas as bases maternas são viáveis economicamente e podem ser utilizadas no sistema de produção de leite e bezerros para venda. Todas as ordens de parto de Holandês x Zebu estudadas são viáveis economicamente.(AU)
The objective was to evaluate the economic viability of a milk production system of F1 Holstein x Zebu cows of different maternal bases and calving order. Lactations data of F1 Holtein x Zebu cows (n=406) of different maternal bases, from the experimental field of the EPAMIG at Felixlândia county (MG state, Brasil) were analyzed. Revenue, cost/effect of operation, total operating, and total cost have been estimated. F1 cows Holstein x Gir had averages of higher costs R$ 3582.30, followed by F1 cows Holstein x Nelogir R$ 3448.06; and the lowest was from cows F1 Holstein x Nellore with R$ 3145.07. The total revenue was higher for Holstein x Gir and Holstein x Nelogir with recipe values of R$ 4394.96 and R$ 4245.61 respectively, and the lowest value of R$ 3976.12 for Holstein x Nellore. The profits were R$812.65; R$ 797.54 and R$ 831.04 for animals of groups Holstein x Gir, Holstein x Nelogir and Holstein x Nellore respectively. All genetic groups are economically viable and can be used in the production of milk and calves for sale. All calving order of Holstein x Zebu studied are viable economically.(AU)

Estudar o relacionamento conjugal e a avaliação da efetividade de intervenções com casais pode promover as habilidades de comunicação, afeto e resolução de problemas. Pesquisas com casais de namorados na literatura são incipientes e acredita-se que ampliar tais comportamentos pode ajudar esses casais. O presente estudo de caso avalia uma intervenção (quatro sessões de avaliação e dez sessões de grupo) com um casal de namorados num delineamento de sujeito único, considerando medidas de linha de base, pré-teste, pós-teste e seguimento, combinado com medidas processuais de expectativa e satisfação com o procedimento conduzido. Os resultados demonstram satisfação com o tratamento, generalização para outros relacionamentos e melhoria do relacionamento em comunicação, afeto e resolução de problemas. Discute-se implicações para a prevenção e futuras pesquisas
The study of the marital relationship and of the evaluation of the effectiveness of interventions with couples can promote communication skills, affection and problem solving. Researches with dating couples are incipient on the literature, and it is believed that extending such behaviors can help those couples. The present case study evaluates an intervention (four evaluation sessions and ten sessions of group) with dating couples, in the design of a single subject, considering measures baseline, pretest, posttest and follow-up, combined with procedural measures of expectation and satisfaction with the procedure conducted. The results show satisfaction with treatment, generalization to other relationships and improvement of the relationship as communication, affection and problem solving. Implications are discussed for future prevention and researches

We investigated the anti-inflammatory, antinociceptive and ulcerogenic activity of a zinc-diclofenac complex (5.5 or 11 mg/kg) in male Wistar rats (180-300 g, N = 6) and compared it to free diclofenac (5 or 10 mg/kg) and to the combination of diclofenac (5 or 10 mg/kg) and zinc acetate (1.68 or 3.5 mg/kg). The carrageenin-induced paw edema and the cotton pellet-induced granulomatous tissue formation models were used to assess the anti-inflammatory activity, and the Hargreaves model of thermal hyperalgesia was used to assess the antinociceptive activity. To investigate the effect of orally or intraperitoneally (ip) administered drugs on cold-induced gastric lesions, single doses were administered before exposing the animals to a freezer (-18ºC) for 45 min in individual cages. We also evaluated the gastric lesions induced by multiple doses of the drugs. Diclofenac plus zinc complex had the same anti-inflammatory and antinociceptive effects as diclofenac alone. Gastric lesions induced by a single dose administered per os and ip were reduced in the group treated with zinc-diclofenac when compared to the groups treated with free diclofenac or diclofenac plus zinc acetate. In the multiple dose treatment, the complex induced a lower number of the most severe lesions when compared to free diclofenac and diclofenac plus zinc acetate. In conclusion, the present study demonstrates that the zinc-diclofenac complex may represent an important therapeutic alternative for the treatment of rheumatic and inflammatory conditions, as its use may be associated with a reduced incidence of gastric lesions.
