1. Short hairpin RNA targeting insulin-like growth factor binding protein-3 restores the bioavailability of insulin-like growth factor-1 in diabetic rats
ABSTRACT Purpose To investigate whether intracavernosal injection of short hairpin RNA for IGFBP-3 could improve erectile function in streptozotocin-induced diabetic rats. Materials and methods After 12 weeks of IGFBP-3 short hairpin RNA injection treatment, intracavernous pressure responses to electrical stimulation of cavernous nerves were evaluated. T

2. Modulação do transporte de prótons em osteoclastos: efeitos da acidose e do fluxo de fluido extracelular. / Modulation of proton transport in osteoclasts. Effects of acidosis and extracellular fluid flow.
Metabolic acidosis can cause a loss of bone mineral and the mechanic stimulation can cause adaptative bone remodeling. The bone resorption characteristic of these bone changes aforementioned depends on the extracellular acidification by osteoclastmediated proton secretion. The H+ secretion by vacuolar H+-ATPase together with Clsecretion through a Cl-/H+ exch

3. Study of the Reactivity of complex ions cis-[Ru (bpy)2(L) (NO)]n+ where L = imidazole, 1-metilimidazole, thiourea and sulfite / Estudo da Reatividade dos Ãons complexos cis-[Ru(bpy)2(L)(NO)]n+ onde L=imidazol, 1-metilimidazol, tioureia e sulfito
We carried out studies of chemical reactivity, electrochemistry and photochemistry of complexes cis-[Ru(bpy)2(L)(NO)](PF6)n, where L = imidazole, 1-methylimidazole, thiourea and sulfite. Were chosen, therefore, two ligands being donors and two with ligands that act as -recipient and the results indicated that the nature and strength of these

4. Estudo de sistemas multicomponentes no processo de injeção cíclica de vapor
No Nordeste brasileiro existem reservatórios de óleos pesados, nos quais se utiliza a injeção de vapor como método de recuperação. Este processo permite diminuir a viscosidade do óleo, aumentando a sua mobilidade e melhorando o volume de óleo a ser recuperado. A injeção de vapor é um método térmico e ocorre na forma contínua ou cíclica. A inj

5. Avaliação do efeito relaxante do BAY 41-2272 em detrusor isolado de coelhos / Evaluation of relaxant effect of BAY 41-2272 in rabbit isolated detrusor
Overactive bladder (OAB) is a highly prevalent condition that affects millions of people worldwide with a profound effect on quality of life. The bladder overactivity is related to spontaneous contractions of the detrusor smooth muscle causing an increase in the intravesical pressure and consequently stimulation of the micturirion reflex. Evidences suggest t

6. Role of nitric oxide and the cyclic guanosine monophosphate dependent patway on the adhesive properties leucocytes of sickle cell disease patients / Ação do oxido nitrico e da via dependente de guanosina monofosfato ciclico nas propriedades adesivas de leucocitos de pacientes com anemia falciforme
Increased leukocyte adhesion to vascular endothelium contributes to vaso-occlusion in sickle cell disease (SCD). Since nitric oxide (NO) bioavailability is decreased in SCD and NO may inhibit leukocyte adhesion, we determined whether stimulation of NO-signalling pathways can decrease the adhesive properties of neutrophils from SCD individuals (SCDneu). SCDne

7. Otimização da injeção cíclica de vapor em reservatório de óleo pesado
Os métodos térmicos viabilizaram a produção de óleo pesado em campos considerados não comerciais pelos métodos convencionais de recuperação. A injeção de vapor, em particular, veio a se consagrar ao longo dos anos e é hoje uma das principais alternativas economicamente viável para o aumento da recuperação dos óleos pesados. Dentre as ramifica

8. Behavioral correlates of the activity of serotonergic and non-serotonergic neurons in caudal raphe nuclei
We investigated the behavioral correlates of the activity of serotonergic and non-serotonergic neurons in the nucleus raphe pallidus (NRP) and nucleus raphe obscurus (NRO) of unanesthetized and unrestrained cats. The animals were implanted with electrodes for recording single unit activity, parietal oscillographic activity, and splenius, digastric and masset

9. Role of the hypothalamic pituitary adrenal axis in the control of the response to stress and infection
The release of adrenocorticotropin (ACTH) from the corticotrophs is controlled principally by vasopressin and corticotropin-releasing hormone (CRH). Oxytocin may augment the release of ACTH under certain conditions, whereas atrial natriuretic peptide acts as a corticotropin release-inhibiting factor to inhibit ACTH release by direct action on the pituitary.

10. Estudo do efeito da dobutamina (Dobutrex) R e da radiação laser sobre a ação hidrosmotica da vasopressina em bexiga de sapo "in vitro"
In the present work the effects of several pharmacological agents in special Dobutamine and a physical agent-Laser radiation - on the events that follow the interaction of Vasopressin with membrane receptors related to syn¬thesis and inactivation of cyclic-AMP in the toad bladder, are described and characterized. Water flow across the membrane was measured

11. Cyclic guanosine 3',5'-monophosphate regulates the calcium current in single cells from frog ventricle.
1. The effect of intracellular perfusion with cyclic AMP and cyclic GMP on Ca2+ current (ICa) was studied in single cells isolated from frog ventricle using the whole-cell patch-clamp technique and a perfused pipette. 2. Intracellular perfusion with cyclic GMP (0.1-20 microM) had no effect on the basal ICa. However, when ICa was increased by isoprenaline or

12. Mechanical, electrical and cyclic nucleotide responses to peptide VIP and inhibitory nerve stimulation in rat stomach.
1. Effects of apamin on electrical and mechanical activities and cyclic nucleotide accumulation in response to vasoactive intestinal peptide (VIP) and intramural nerve stimulation were investigated in isolated circular strips of the rat stomach in the presence of atropine and guanethidine. 2. Circular muscles generated rhythmic contractions and slow waves in
