Fluoride and sodium trimetaphosphate (TMP) release from fluoride varnishes supplemented with TMP

Braz. oral res. (Online); 30 (1), 2016
Abstract This study assessed fluoride (F) and sodium trimetaphosphate (TMP) release into artificial saliva from varnishes containing 0%, 2.5%, and 5% NaF, supplemented or not with 5% TMP. The varnishes were applied on polyester sheets (n = 8/group), and F and TMP released into artificial saliva were meas...

Prevalence of periodontopathogens and Candida spp. in smokers after nonsurgical periodontal therapy - a pilot study

Braz. oral res. (Online); 30 (1), 2016
Abstract This pilot study aimed to evaluate the influence of smoking on clinical and microbiological parameters after nonsurgical periodontal therapy. Forty-eight subjects were grouped into smokers (SM, n = 24) and nonsmokers (NS, n = 24) and paired according to gender, age, ethnicity, and periodontal st...

Effect of new innovative restorative carbomised glass cement on intrapulpal temperature rise: an ex-vivo study

Braz. oral res. (Online); 30 (1), 2016
Abstract This study aimed to evaluate the temperature changes that occurred in the pulp chamber when using GCP Glass Carbomer Fill (GCP) and two different resin-modified glass-ionomer (RGI) restorative materials at different dentin thicknesses. A standardized Class I occlusal cavity with 1 mm or 2 mm den...

Antimicrobial activity and substantivity of Uncaria tomentosa in infected root canal dentin

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to analyze the antimicrobial activity and substantivity of Uncaria tomentosa Willd DC (cat's claw, CC) in root dentin contaminated with Enterococcus faecalis. Forty-eight human premolars were contaminated with E. faecalis (ATCC 29212) and randomly divided into four grou...

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...

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...

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...

Novel identification and characterisation of Transient receptor potential melastatin 3 ion channels on Natural Killer cells and B lymphocytes: effects on cell signalling in Chronic fatigue syndrome/Myalgic encephalomyelitis patients

Biol. Res; 49 (), 2016
BACKGROUND: Transient receptor potential melastatin 3 (TRPM3) cation channels are ubiquitously expressed by multiple cells and have an important regulatory role in calcium-dependent cell signalling to help maintain cellular homeostasis. TRPM3 protein expression has yet to be determined on Natural Killer ...

Progress in tear microdesiccate analysis by combining various transmitted-light microscope techniques

Biol. Res; 49 (), 2016
BACKGROUND: Tear desiccation on a glass surface followed by transmitted-light microscopy has served as diagnostic test for dry eye. Four distinctive morphological domains (zones I, II, III and transition band) have been recently recognized in tear microdesiccates. Physicochemical dissimilarities among th...

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...
