25. Role of estradiol on bovine luteolysis: estradiol stimulates PGF2&alpha througthout P4 receptor activation in the endometrium? / As funções do estradiol no processo da luteólise em bovinos: o estradiol estimula PGF2α através da ativação de receptores de P4 no endométrio?
Estradiol (E2) is essential for triggering luteolysis in ruminants. The low E2 concentrations after follicular ablation prolongs luteolysis instead of E2 injections in late luteal phase stimulate prostaglandin F2α (PGF2α) and luteolysis. The E2 could act in endometrium avoiding progesterone (P4 ) to stimulate PGF 2α secretion. A P4 antagoni

26. O alcance e a dimensão do princípio da proporcionalidade relacionado à impenhorabilidade da execução, como forma de efetividade do processo executivo
This strong research objects a study about the relation of principle of proportionality with the question of pledge on civil execution objecting effectivity. Initially we want to permit that the reader have a constitutional vision essential of the principle of proportionality. Is in vogue actually a theme about of collisions of fundamental rights and mechani

27. Avaliação da eficácia de placas estabilizadoras com padrão de guia balanceada bilateral no controle dos desarranjos internos da ATM / EVALUATION OF THE EFFECTIVITY OF STABILIZATION SPLINTS WITH BILATERAL BALANCED GUIDANCE FOR THE CONTROL OF INTERNAL TMJ DERANGEMENTS
The aim of this study was to evaluate the effect of balanced splints with bilateral balanced guidance, canine guidance and nonoccluding splints. For that purpose, a study sample was employed comprising 57 individuals presenting with signs and symptoms of disc displacement with reduction and complaint of TMJ pain and tenderness to palpation of the TMJ at leas

28. Pollinators in strawberry crop(Fragaria x ananassa Duchesne - Rosaceae) / Estudo de agentes polinizadores em cultura de morango (Fragaria x ananassa Duchesne - Rosaceae)
The aims of this study were: to investigate potencial pollinators of strawberry crops in commercial fields; to verify the contribution of several pollination agents on strawberry productivity, studying the floral and reproductive biology of some commercial cultivars; to evaluate the possibility of the rational use of stingless bees in strawberry pollination

29. Esterilização por óxido de etileno: estudo da efetividade esterilizante de misturas não explosivas e compatíveis com a camada de ozônio / Ethylene oxide sterilization: effectivity study of non explosive blends and compatible with ozone layer
Tendo em vista a importância do processo esterilizante aplicado a produtos farmacêuticos e aos produtos médico-hospitalares, distintos métodos foram desenvolvidos de forma a possibilitar sua aplicação, inclusive a materiais termossensíveis. Neste contexto, o processo que se tornou mais amplamente empregado consiste naquele utilizando o óxido de etile

31. Operating microscope eyepiece heaters.
Precipitation of water vapour from expired air on to exposed eyepiece lenses of operating microscopes can seriously interfere with the surgeon's view. By warming these optical surfaces to temperatures well above the dew point of expired air this problem is eliminated. A pair of small heaters were designed to clamp over the eyepiece tubes of a standard opera

32. Mode of action of immunological adjuvants: some physicochemical factors influencing the effectivity of polyacrylic adjuvants.
The adjuvant effects of different polyacrylic products and monomers were tested. Influenza vaccine was used as a model antigen. Addition of monomers resulted in a decrease in the antibody response, though adjuvant activity of the monomers should be expected according to some theories on adjuvant action. The particle size of the polymer adjuvants proved to be

33. Effects of Long-Term Preservation of Frankia Strains on Infectivity, Effectivity, and In Vitro Nitrogenase Activity
Frankia strain HFP ArI3 which had been preserved for 27 months by being lyophilized, frozen in glycerol, or stored in complex medium was successfully used as an inoculum after being subcultured for inducing nodulation and nitrogen fixation of Alnus rubra. Glycerol-preserved HFP ArI3 produced significantly lower rates of nitrogenase activity than did lyophili

34. Atenolol eye drops in glaucoma: a double-masked, controlled study.
Guttae atenolol 4% (Tenormin), a pure beta1-blocking (i.e., cardioselective) drug, produced a median overall fall of 5-6 mmHg (range 3-2 to 13-2 mmHg) in the first tonometrised eyes of 7 patients with open-angle glaucoma or ocular hypertension and 1 with closed-angle glaucoma (off any treatment for the whole of the day preceding each test day) after allowanc

35. Increased inactivation of Saccharomyces cerevisiae by protraction of UV irradiation.
The principle of equi-effectivity of the product of intensity and exposure time (principle of Bunsen-Roscoe) of UV irradiation has been assumed to be valid for the inactivation of microorganisms in general. Earlier studies claimed higher survival of Escherichia coli B/r with fractionated irradiation compared with single-exposure survival. However, data on th

36. Normal viability and altered pharmacokinetics in mice lacking mdr1-type (drug-transporting) P-glycoproteins
The mdr1-type P-glycoproteins (P-gps) confer multidrug resistance to cancer cells by active extrusion of a wide range of drugs from the cell. To study their physiological roles, we have generated mice genetically deficient in the mdr1b gene [mdr1b (−/−) mice] and in both the mdr1a and mdr1b genes [mdr1a/1b (−/−) mice]. In spite of the host of functio
