1. Urinary Glycosaminoglycan Electrophoresis With Optimized Keratan Sulfate Separation Using Peltier System for the Screening of Mucopolysaccharidoses
Abstract The purpose of this communication is to indicate a simple and rapid method with a small volume of urine sample to detect urine glycosaminoglycan (GAG) and serve as a screening procedure for mucopolysaccharidoses (MPSs). Total GAG measurement for patients with MPS disorders is considered to be the first step in diagnosis of those heterogeneous group

2. Mutagenicity induced by the hydroalcoholic extract of the medicinal plant Plathymenia reticulata Benth
Plathymenia reticulata Benth has an anti-inflammatory effect and is capable of neutralizing the neuromuscular blockade induced by Bothrops jararacussu or Crotalus durissus terrificus venoms, probably by precipitating venom proteins (an effect caused by plant tannins). The present study aimed to evaluate the mutagenic activity of P. reticulata by using the Sa

3. Auroral electron precipitating energy during magnetic storms with peculiar long recovery phase features / Energia de precipitação auroral de elétrons durante tempestades magnéticas com características peculiares de longa fase de recuperação
Aurora, light emissions generated by collisions between energetic electrons and atmospheric particles, is often seen in the polar region. Although much is known about the aurora, there are still many questions unanswered. For example, it is not well known what is the source of the energetic particles or by what processes the particles are energized. Understa

4. Análise da trajetória e da circulação de sistemas precipitantes / Analysis of the trajectory and circulation of the precipitating systems
A partir da técnica " extit{Least Square- Velocity Azimuth Display}" aplicada aos dados de velocidade radial, obtida a partir da varredura volumétrica de um dos radares da rede do Departamento de Controle do Espaço Aéreo, foi obtida uma metodologia que permite a recuperação do vento médio horizontal. Além disso, com a sequência temporal dos perfis v

5. Study of the isoelectric precipitation of porcine insulin in aqueous solutions with carbon dioxide / Estudo da precipitação isoeletrica da insulina suina em soluções aquosas com o dioxido de carbono
Precipitation is a technique frequently employed in downstream process for the recovery of proteins from aqueous solutions. One example of such technique is the isoelectric precipitation, which consists of the adjustment of solution pH to the value where the protein has zero net charge, the isoelectric point, pI. Commonly, mineral acids and bases are used fo

6. Acute intermittent porphyria: clinical study of 37 cases. / Porfiria aguda intermitente: estudo clínico de 37 casos.
Acute intermittent porphyria is an autosomal dominant disease, caused by a disturbance in the heme biosynthetic pathway, secondary to the reduction on the levels of uroporphyrinogen-I-synthetase enzyme. Clinical manifestations involve central and peripheral nervous system. The diagnosis is based on the elevated urinary excretion of porphyrins precursors d-am

7. Antibodies to cellular antigens in Sjögren's syndrome.
An extract of human lymphocytes from continous cell culture was used as the antigen source to detect antibodies in sera of patients with Sjögren's syndrome (SS). Using double diffusion in agarose, 85 per cent of a selected group of patients had precepating antibodies. Three precipitating antigen-antibody systems were detected and were shown to be different

9. Serological differentiation between infected and vaccinated cattle by using purified soluble antigens from Brucella abortus in a hemagglutination system.
Serological tests used in current brucellosis eradication schemes, such as bacterial tube agglutination, do not readily distinguish between infected animals and those immunized with strain 19 or 45/20 Brucella abortus vaccines. In this study, sera from naturally infected cattle were used to identify serologically important antigens in extracts of virulent B.

10. Simple and Reliable Method To Precipitate Proteins from Bacterial Culture Supernatant
A simple and reliable method for precipitating protein from bacterial culture supernatants based on a pyrogallol red-molybdate-methanol (PRMM) protocol has been developed and applied for the analysis of proteins secreted by a bacterial type III secretion system. PRMM-based precipitation has been shown to be more efficient and robust than are conventional pro

11. Rabies Group-Specific Ribonucleoprotein Antigen and a Test System for Grouping and Typing of Rhabdoviruses
Cell-associated ribonucleoprotein (RNP) was isolated from BHK-21 cells infected with several strains of rabies and rabies-related viruses. The RNP-antigen from rabies and related viruses induced the formation of complement-fixing, precipitating, and immunofluorescent antibodies, and proved to be the group-specific antigen common to all rabies viruses. Antige

12. Stabilization of Isolated Photosystem II Reaction Center Complex in the Dark and in the Light Using Polyethylene Glycol and an Oxygen-Scrubbing System 1
The photosystem II reaction center as isolated (O Nanba, K Satoh [1987] Proc Natl Acad Sci USA 84: 109-112) is quite dilute and very unstable. Precipitating the complex with polyethylene glycol and resuspending it in buffer without detergent concentrates the reaction center and greatly improves its stability at 4°C in the dark as judged by light-induced ele
