In vitro and in vivo evaluation of nano-based films for buccal delivery of zolpidem

Braz. oral res. (Online); 30 (1), 2016
Abstract Insomnia is becoming increasingly prevalent in the world general population. Therapies used by patients include over-the-counter therapies, herbal and dietary supplements, and pharmacological or nonpharmacological treatments. Among these, zolpidem is a pharmacological treatment popularly used fo...

Aged garlic extract and S-allylcysteine prevent apoptotic cell death in a chemical hypoxia model

Biol. Res; 49 (), 2016
BACKGROUND: Aged garlic extract (AGE) and its main constituent S-allylcysteine (SAC) are natural antioxidants with protective effects against cerebral ischemia or cancer, events that involve hypoxia stress. Cobalt chloride (CoCl2) has been used to mimic hypoxic conditions through the stabilization of the...

Wnt-5a-regulated miR-101b controls COX2 expression in hippocampal neurons

Biol. Res; 49 (), 2016
BACKGROUND: Wnt-5a is a member of the WNT family of secreted lipoglycoproteins, whose expression increases during development; moreover, Wnt-5a plays a key role in synaptic structure and function in the adult nervous system. However, the mechanism underlying these effects is still elusive. MicroRNAs (miR...

Carotid body Thermoreceptors, sympathetic neural activation, and cardiometabolic disease

Biol. Res; 49 (), 2016
The carotid body (CB) is the main peripheral chemoreceptor that senses the arterial PO2, PCO2 and pH. In response to hypoxemia, hypercapnia and acidosis, carotid chemosensory discharge elicits reflex respiratory, autonomic and cardiovascular adjustments. The classical construct considers the CB as the ma...

A high-fat diet decreases GABA concentration in the frontal cortex and hippocampus of rats

Biol. Res; 49 (), 2016
BACKGROUND: It has been proposed that the γ-aminobutyric acid (GABA) plays a key role in the regulation of food intake and body weight by controlling the excitability, plasticity and the synchronization of neuronal activity in the frontal cortex (FC). It has been also proposed that the high-fat diet (HF...

Antitumor and anti-angiogenic potentials of isolated crude saponins and various fractions of Rumexhastatus D. Don

Biol. Res; 49 (), 2016
BACKGROUND: Cancer, being the foremost challenge of the modern era and the focus of world-class investigators, gargantuan research is in progress worldwide to explore novel therapeutic for its management. The exploitation of natural sources has been proven to be an excellent approach to treat or minify t...

Salinity-induced changes in the morphology and major mineral nutrient composition of purslane (Portulaca oleracea L) accessions

Biol. Res; 49 (), 2016
This study was undertaken to determine the effects of varied salinity regimes on the morphological traits (plant height, number of leaves, number of flowers, fresh and dry weight) and major mineral composition of 13 selected purslane accessions. Most of the morphological traits measured were reduced at v...

50 years of amino acid hydrophobicity scales: revisiting the capacity for peptide classification

Biol. Res; 49 (), 2016
BACKGROUND: Physicochemical properties are frequently analyzed to characterize protein-sequences of known and unknown function. Especially the hydrophobicity of amino acids is often used for structural prediction or for the detection of membrane associated or embedded β-sheets and α-helices. For this p...

Potential role of marine algae extract on 3T3-L1 cell proliferation and differentiation: an in vitro approach

Biol. Res; 49 (), 2016
BACKGROUND: From ancient times, marine algae have emerged as alternative medicine and foods, contains the rich source of natural products like proteins, vitamins, and secondary metabolites, especially Chlorella vulgaris (C. vulgaris) contains numerous anti-inflammatory, antioxidants and wound healing sub...

Anti-inflammatory effects of Salvia plebeia R. Br extract in vitro and in ovalbumin-induced mouse model

Biol. Res; 49 (), 2016
BACKGROUND: Asthma is an increasing global health problem, and novel strategies to prevent or ameliorate the condition are needed. Here, the effects of 80 % ethanol extracts of Salvia plebeia R. Br. (SE) on an induced inflammatory response were investigated RESULTS: Salvia plebeia R. Br. inhibited produc...
