1. Goitrogenic/antithyroidal potential of moringa leaves (Moringa oleifera) and spinach (Spinacia oleracea) of Indian origin on thyroid status in male albino rats
Moringa leaves and spinach used as vegetables containing cyanogens and polyphenols having suspected antithyroidal activity; however, detailed studies in this aspect found unavailable. Goitrogenic/antithyroid potentiality of those plant foods of Indian origin was evaluated. To explore the goitrogenic/antithyroid effect of those plant foods cyanogenic glucosid

2. Development of an Extraction Protocol for Fetal Sexing from the Fourth Week of Gestation by Real Time PCR
Abstract Low number of fetal cells in maternal blood limited the use of fetal materials in diagnostic and clinical applications. This research developed a technology which allowed the extraction of fetal DNA by a non-invasive method that offers no risk to the mother or fetus. A total of 132 pregnant women participated in this inquiry. The DNA extraction was

3. Differential Molecular Signature of Human Saliva Using ATR-FTIR Spectroscopy for Chronic Kidney Disease Diagnosis
Resumo Os sintomas da doença renal crônica (DRC) são frequentemente inespecíficos ou ausentes nos estágios iniciais desta doença. Desta forma, existe uma demanda para o desenvolvimento de plataformas com baixo custo, não-invasivas e com alta acurácia para o diagnóstico da DRC. Nós hipotetizamos que o nível dos componentes salivares se alteram pela

4. Synthesis and Characterization of Non-Linear Optical Crystal of Manganese Mercury Thiocyanate Glycol Monomethyl Ether
The design and synthesis of organic nonlinear optical (NLO) crystals are a promising area of current research in materials science. Organic materials are found to possess better non linear optical properties when compared to inorganic materials. Recently, there has been a widespread interest in the metal-organic coordination compounds, which are a combinatio

5. Synthesis and Characterization of Nanopore MoVI-Imprinted Polymer and Its Application as Solid Phase for Extraction, Separation and Preconcentration of Molybdenum Ions from Water Samples
The purpose of this study is to prepare a new ion imprinted polymer for MoVI with high selectivity. Ion-imprinted polymer (IIP) particles were synthesized by thermally copolymerization. For the synthesis of the ion imprinted polymer, the ion pair of (MoVI-thiocyanate) and NR4+ was used. The ion pair was precipitated in an aqueous phase and then dissolved in

6. Estudo do teste de Scott via técnicas espectroscópicas: um método alternativo para diferenciar cloridrato de cocaína e seus adulterantes
Cocaine is usually seized mixed with a wide variety of adulterants such as benzocaine, lidocaine, caffeine, and procaine. The forensic identification of cocaine in these street drug mixtures is normally performed using colorimetric testing kits, but these tests may suffer from interferences, producing false-positive results. Here, we describe the use of anal

7. Desenvolvimento de um equipamento portátil e de sistema de análises em fluxo empregando multicomutação. Determinação fotométrica de ferro em águas de rios / Development of a portable equipment and a flow analysis system employing multicommutation. Photometric determination of iron in river waters
Iron is the most abundant element on Earth and plays an important role in biogeochemical cycles. In this work, an automatic analytical procedure was developed for the photometric determination of iron in river waters, employing a LED-based photometer and solenoid mini-pumps for solution handling. The proposed procedure was based on the reaction between iron

8. Electroless deposition of bis(4'-(4-Pyridyl)-2,2':6',2''-terpyridine)iron(II) thiocyanate complex onto carbon nanotubes modified glassy carbon electrode: application to simultaneous determination of ascorbic acid, dopamine and uric acid
Um eletrodo de carbono vítreo modificado por nanotubos de carbono de paredes múltiplas (NTCPM) e pelo complexo tiocianato de bis(piterpi) ferro(II) (piterpi = 4'-(4-piridil)-2,2':6',2"-terpiridina) foi investigado através de métodos voltamétricos em solução de tampão acetato (pH 5). A performance do eletrodo modificado pelo complexo de ferro(II)/NTCP

9. High-yield production of scutellaria radix flavonoids (baicalein, baicalin and wogonin) by liquid-culture of Scutellaria baicalensis root-derived cells
Production of baicalein, baicalin and wogonin by liquid culture of Scutellaria baicalensis cells derived from the plant root was studied. The maximum production obtained were 119 mg/L of baicalein at two week, 1372 mg/L of baicalin at eight week, and 14 mg/L of wogonin at two week. In addition, the production of baicalin was drastically increased to 1000 mg/

11. Highly selective transport of mercury(II) ion through a bulk liquid membrane
In this work carrier-facilitated transport of mercury(II) against its concentration gradient from aqueous 0.04 M hydrochloric acid solution across a liquid membrane containing isopropyl 2-[(isopropoxycarbothiolyl)disulfanyl]ethane thioate (IIDE) as the mobile carrier in chloroform has been investigated. Sodium thiocyanate solution (1.6 M) was the most effici

12. Potencial antioxidante de extratos de resíduos de acerolas (Malpighia Emarginata D.C.) em diferentes sistemas modelos e na estabilidade oxidativa do óleo de soja
The observation that the plants have biologically active substances, mainly polyphenols, that provide benefits to health, has driven studies on the antioxidant property. Thus, considering that the agri-industrial waste from acerola also contains phenolic compounds, this study was carried out to determine the procedure for extraction of polyphenols and the an
