1. Intranasal mucoadhesivemicroemulsion for neuroprotective effect of curcuminin mptp induced Parkinson model
ABSTRACT This study was to investigate the neuroprotective effect of curcumin against inflammation-mediated dopaminergic neurodegeneration in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mice model of Parkinson's disease (PD). Curcumin loaded sodium hyaluronate based mucoadhesive microemulsion (CMME) was developed by using Box Behnken design of Respon

2. A new method to determine the density and water absorption of fine recycled aggregates
The construction industry keeps on demanding huge quantities of natural resources, mainly minerals for mortars and concrete production. The depletion of many quarries and environmental concerns about reducing the dumping of construction and demolition waste in quarries have led to an increase in the procuring and use of recycled aggregates from this type of

3. Respostas cardiorrespiratórias promovidas pela ativação de receptores glutamatérgicos e purinérgicos no núcleo do trato solitário / Cardiorespiratory responses produced by activation of the glutamatergic and purinergic receptors of nucleus of the solitary tract
O sistema nervoso central (SNC) possui um papel fundamental na manutenção da composição e do volume dos líquidos corporais, para a adequada perfusão tecidual. Uma importante área do SNC que recebe aferências cardiorrespiratórias é o núcleo do trato solitário (NTS) que possui vários tipos de neurotransmissores, dentre eles o L-glutamato e adenosi

4. Changes in sodium appetite evoked by lesions of the commissural nucleus of the tractus solitarius
Ablation of the area postrema/caudal nucleus of the tractus solitarius (NTS) complex increases sodium intake, but the effect of selective lesions of the caudal NTS is not known. We measured depletion-induced sodium intake in rats with electrolytic lesions of the commissural NTS that spared the area postrema. One day after the lesion, rats were depleted of so

5. Antidipsogenic effects of central adenosine-5'-triphosphate
Besides other physiological functions, adenosine-5'-triphosphate (ATP) is also a neurotransmitter that acts on purinergic receptors. In spite of the presence of purinergic receptors in forebrain areas involved with fluid-electrolyte balance, the effect of ATP on water intake has not been investigated. Therefore, we studied the effects of intracerebroventricu

6. Efeito do maracujá (Passiflora incarnata) sobre a morfometria de hepatócitos da tilápia do Nilo (Oreochromis niloticus) / Effect of Passion fruit (Passiflora incarnata) on the hepatocytes morphometry of Nile tilapia (Oreochromis niloticus)
Effects of Passion fruit (Passiflora incarnata) dry extract administration on hepatocyte morphometry of juveniles Nile tilapias (Oreochromis niloticus) were investigated. Male isolated fish (86,50 ± 10,17 g) were daily fed (28 days) with extruded commercial ration (32% crude protein - 2% biomass) containing the extract diluted in sodium alginate in gr

7. Nutritional assessment of heart failure patients after listing for cardiac transplantation / Avaliação nutricional de pacientes portadores de insuficiência cardíaca no período pré-transplante cardíaco
Malnutrition is frequently present in patients with heart failure (HF) and is associated with an increase in morbidity and mortality. The objective of this study was to evaluate nutritional status of patients with refractory HF waiting for cardiac transplantation. Nutritional evaluation was done with the use of subjective global assessment, complete anthropo

8. Reologia de Biodiesel de origens diversas e das misturas Diesel/Biodiesel
Cost and depletion of petroleum derived fuels are increasing, thus alternative fuels are quite required. Biodiesel (B100), which is comprised of fatty acid methyl (or ethyl) esters (FAMEs/FAEEs) derived from vegetable oils, animal fats or waste oils mainly through transesterification, is an alternative source of energy. It is renewable, available locally, bi

9. Water deprivation and the double- depletion hypothesis: common neural mechanisms underlie thirst and salt appetite
Water deprivation-induced thirst is explained by the double-depletion hypothesis, which predicts that dehydration of the two major body fluid compartments, the extracellular and intracellular compartments, activates signals that combine centrally to induce water intake. However, sodium appetite is also elicited by water deprivation. In this brief review, we

10. Sodium appetite specificity: a possible hormonal contribution. / Especificidade do apetite ao sódio: uma possível contribuição hormonal.
A hipótese do sinergismo entre dois hormônios responsáveis pela conservação de sódio, a aldosterona e a ANG II, explica uma característica do apetite ao sódio, a ingestão de NaCl hipertônico em um animal hipovolêmico. Ingestão de NaCl hipertônico pode ser induzida em ratos normovolêmicos que receberam um tratamento combinado de mineralocorticó

11. Chronic excitotoxic lesion of the dorsal raphe nucleus induces sodium appetite
We determined if the dorsal raphe nucleus (DRN) exerts tonic control of basal and stimulated sodium and water intake. Male Wistar rats weighing 300-350 g were microinjected with phosphate buffer (PB-DRN, N = 11) or 1 µg/0.2 µl, in a single dose, ibotenic acid (IBO-DRN, N = 9 to 10) through a guide cannula into the DRN and were observed for 21 days in order

12. Brain serotonin depletion enhances the sodium appetite induced by sodium depletion or beta-adrenergic stimulation
Objetivamos avaliar a influência da depleção cerebral de serotonina no apetite por sódio. Ratos depletados de serotonina através da administração sistêmica de paraclorofenilalanina (300 mg/kg, ip, por 2 dias) exibiram intensa resposta natriorexigênica induzida pela depleção de sódio (furosemida, 20 mg/kg, sc, 24 h antes da oferta de água e NaCl
