1. Bioactive Bioflavonoids from Platonia insignis (Bacuri) Residues as Added Value Compounds
Platonia insignis fruit, popularly known as bacuri, is traditionally used in folk medicine for its anti-inflammatory and antioxidant properties. Therefore, this study determined the chemical composition and biological activities of the bacuri’s shell and seeds extracts, considered residues from its consumption and industrial uses. Four biflavonoids (GB-2a,

2. Incidence of Inborn Errors of Metabolism by Expanded Newborn Screening in a Mexican Hospital
Abstract Newborn screening for the detection of inborn errors of metabolism (IEM), endocrinopathies, hemoglobinopathies, and other disorders is a public health initiative aimed at identifying specific diseases in a timely manner. Mexico initiated newborn screening in 1973, but the national incidence of this group of diseases is unknown or uncertain due to th

3. ANÁLISE POR INJEÇÃO SEQUENCIAL COM DETECÇÃO POR VOLTAMETRIA DE ONDA QUADRADA PARA DETERMINAÇÃO DE As(III) EM AMOSTRAS DE ÁGUAS USANDO ELETRODO DE OURO
A sequential injection method with square wave anodic stripping voltammetry (SI-SWASV) using screen printed and crystalline gold electrode was developed for determination of As(III). The carrier solution used for electrode conditioning and stripping medium was composed of 0.050 mol L-1 HCl, whereas the supporting electrode for samples (deposition medium) was

4. The use of singleplex and nested PCR to detect Batrachochytrium dendrobatidis in free-living frogs
Many microorganisms are able to cause diseases in amphibians, and in the past few years one of the most reported has been Batrachochytrium dendrobatidis. This fungus was first reported in Brazil in 2005; following this, other reports were made in specimens deposited in museum collections, captive and free-living frogs. The aim of this study was to compare si

5. Leptospirosis in animals and human contacts in Egypt: broad range surveillance
INTRODUCTION: Leptospirosis is a re-emerging zoonotic disease of humans and animals worldwide. The disease is caused by pathogenic species of the genus Leptospira. These organisms are maintained in nature via chronic renal infection of carrier animals, which excrete the organisms in their urine. Humans become infected through direct or indirect exposure to

6. Efficacy of chemomechanical caries removal in reducing cariogenic microbiota: a randomized clinical trial
The aim of this study was to compare the efficacy of chemochemical methods (Carisolv™ and Papacárie®) versus the manual method (excavators) in reducing the cariogenic microbiota in dentine caries of primary teeth. Forty-six healthy children (5 to 9 years old) having at least one primary tooth with a cavitated dentine carious lesion were included in the s

7. Microencapsulation of Bifidobacterium animalis subsp. lactis and Lactobacillus acidophilus in cocoa butter using spray chilling technology
In the present study, the cells of Bifidobacterium animalis subsp. lactis (BI-01) and Lactobacillus acidophilus (LAC-04) were encapsulated in cocoa butter using spray-chilling technology. Survival assays were conducted to evaluate the resistance of the probiotics to the spray-chilling process, their resistance to the simulated gastric and intestinal fluids (

8. Epidemiology of the viral hepatitis B and C in female prisoners of Metropolitan Regional Prison Complex in the State of Goiás, Central Brazil
INTRODUCTION: Little information regarding hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among Brazilian female prisoners exists. This study investigated the prevalence and risk factors associated with HBV and HCV infections and identified viral genotypes among female prisoners in Goiás, Central Brazil. METHODS:Women incarcerated in the lar

9. Ampliação do uso da técnica de espectrometria de absorção atômica utilizando tubo metálico na chama para determinação de prata / Enlarging the use of thermospray flame furnace atomic absorption spectrometry for determination of silver
Thermospray flame furnace atomic absorption spectrometry (TS-FF-AAS) uses a metallic tube on the flame of the atomic absorption spectrometer. The sample is introduced in the tube by a ceramic capillary. In the development of this method, the parameters involved were studied and the optimal conditions consist of using air as carrier at 0.4 mL min, 200 mL of s

10. Isolation and identification of feline calicivirus and feline herpesvirus in Southern Brazil
Feline calicivirus (FCV) and feline herpesvirus type 1 (FHV-1) are the two primary causes of upper respiratory tract disease in cats. The aim of this study was to demonstrate the distribution of FCV and FHV-1 among the feline population of several counties in Rio Grande do Sul State, Brazil. To this end, conjunctival and nasal swabs were collected from 302 c

12. Direct determination of Cu, Mn, Pb, Zn in beer by thermospray flame furnace atomic absorption spectrometry.
In this work, thermospray flame furnace atomic absorption spectrometry (TS-FF-AAS) was employed for Cu, Mn, Pb, and Zn determination in beer without any sample digestion. The system was optimized and calibration was based on the analyte addition technique. A sample volume of 300 Al was introduced into the hot Ni tube at a flow-rate of 0.4 ml min 1 using 0.14
