1. Development and validation of a simple and rapid way to generate low volume of plasma to be used in point-of-care HIV virus load technologies
ABSTRACT A new point-of-care HIV viral load, mPIMA HIV-1/2 VL, Abbott, USA, has been recently developed. This point-of-care viral load requires no skilled person to run and uses a small plasma volume (50 µL). However, obtaining 50 µL of plasma can be a challenge in limited resource settings. We validated a simple and easy method to obtain enough amount of

2. Análise quantitativa do corante azul de Evan extravasado do interior das câmaras internas dos implantes por suas interfaces protéticas nas condições: Hexágono Externo (HE) - Hexágono Interno (HI) - Cone Morse (CM) / Quantitative analysis of Evans blue dye leakage from internal implant chambers through their prosthetic interfaces under the following conditions: External Hexagon (HE) Internal Hexagon (IH) Morse Cone (MC)
Research and studies seek to evaluate the capacity of adaptation and sealing between the implant-intermediate connections of different dental implant systems. It has recently been observed that in implants with screw-retained abutments, various phenomena, such as screw4 loosening and fracture, rotation and fracture of the abutment with bacterial penetration

3. Perda localizada de carga em conectores utilizados em microirrigação / Local head losses in the connectors used in microirrigation
As perdas localizadas de carga são elementos frequentemente negligenciados em dimensionamento de sistemas de irrigação, afetando a uniformidade de aplicação de água. Algumas peças acessórias não possuem equações que estimem estas perdas de forma simples e eficiente. Este trabalho foi desenvolvido com o objetivo de ajustar uma equação que estime

4. Desenvolvimento e avaliação de um sistema de irrigação com ultra baixa vazão utilizando microtubos ramificados / Development and evaluation of an irrigation system with ultra low flow using microtubes branched
Para o desenvolvimento de uma agricultura sustentável no Brasil é imprescindível realizar investimentos nos setores que desenvolvem tecnologias inovadoras de baixo custo e adaptadas às condições peculiares do país, em substituição a dependência por produtos importados de alto custo e inacessíveis a maioria dos pequenos produtores. Nesse sentido, o

5. A micro-spreading improvement for spermatogenic chromosomes from Triatominae (Hemiptera-Reduviidae)
Cytogenetics of triatomines have been a valuable biological tool for the study of evolution, taxonomy, and epidemiology of these vectors of Trypanosoma cruzi. Here we present a single microtube protocol that combines micro-centrifugation and micro-spreading, allowing high quality cytogenetic preparations from male gonadal material of Rhodnius prolixus and Tr

6. Modeling, development of software for designing, and evaluation of drip irrigation systems with microtubes. / Modelagem, desenvolvimento de software para dimensionamento, e avaliação de sistemas de irrigação por gotejamento com microtubos.
The use of microtubes has been increasing especially in poor countries of Asia and Africa, where international organizations struggle for the development of small farmers through the insertion of low cost technologies. Within this context and with the intention of offering technical and scientific background for the development of a low cost and high technol

7. Microtube coagulase test for detection of coagulase-positive staphylococci.
Studies were performed to determine the sensitivity and specificity of a new microtube method for the detection of coagulase production by Staphylococcus aureus. Rabbit plasma containing EDTA was added to and lyophilized in API microtubes. Two standard coagulase plasmas containing EDTA were used in the conventional macrotube test and served as a basis for co

8. Accuracy of a rapid carbohydrate oxidation microtube method for identification of nonfermentative gram-negative bacilli.
A rapid carbohydrate oxidation microtube system (Carr Microbiologicals, Wichita, Kans.), designed for detecting the saccharolytic activity of gram-negative, nonfermenting bacilli, was evaluated and compared with the conventional oxidation-fermentation method. The oxidation of glucose, maltose, lactose, and xylose was tested with 430 strains of Pseudomonas, A

9. Evaluation of the API 20 c microtube system for the identification of clinically important yeasts.
The API 20 C microtube system containing 20 biochemical tests for the identification of yeasts was compared with conventional tests used in the Mayo Clinic mycology laboratory. Three hundred isolates of clinically important yeasts were studied, and agreement of the carbohydrate fermentation and assimilation tests between the systems was good. The API 20 C re

10. Clinical evaluation of the rapid carbohydrate degradation microtube method for identification of Neisseria species.
The rapid carbohydrate degradation (Carr Microbiologicals Wichita, Kans.) microtube method is a new test system designed for the identification of Neisseria spp. The system consists of four microtubes containing different carbohydrates in a peptone-Bitone basal medium. This method was evaluated for accuracy and speed in identifying species of Neisseria. Of t

11. Evaluation of API microtube GT system for detection of germ tube production by clinically significant yeasts.
A total of 152 fresh consecutive yeast isolates were tested for their ability to produce germ tubes by the API GT system (Analytab products, Plainview, N.Y.) and by a conventional method. The API system was found to be less sensitive than the conventional method. The costs per test by the API system and the conventional method were $0.76 and $0.39, respectiv

12. Rapid determination of minimum inhibitory concentrations of antimicrobial agents by the Autobac method: a collaborative study.
Four laboratories collaborated in an evaluation of the Autobac minimum inhibitory concentration (MIC) test system. The MICs of ranges of MICs determined in this system were compared with the MICs obtained with a microtube modification of the International Collaborative Study broth dilution technique. A total of 1,260 strains, mostly recent clinical isolates
