This study demonstrates the preparation, structure, and properties of polymer-impregnated wood (PIW) based on novel Muchelia macclurei wood through the in-situ polymerization of vinyl and functional monomers. Mixed monomers of glycidyl methacrylate (GMA) and ethylene glycol dimethacrylate (EGDMA) (2:1 molar ratio) were effectively vacuum/pressure impregnated into the cellular structure of the f...

We used sentinel animal enclosures to measure the rate of infestation by the Chagas disease vector, Triatoma infestans, in an urban community of Arequipa, Peru, and to evaluate the effect of deltamethrin-impregnated netting on that rate. Impregnated netting decreased the rate of infestation of sentinel enclosures (rate ratio, 0.23; 95% confidence interval, 0.13-0.38; P < 0.001), controlling for...

In this study an attempt is made to combine the beneficial effects of probiotics with fruit and vegetables by applying the vacuum impregnation process. Apple cylinders were impregnated either with commercial apple juice containing Saccharomyces cerevisiae, and with whole milk or apple juice containing 10 or 10 cfu/ml of Lactobacillus casei (spp. rhamnosus). Impregnated apple samples contained a...

The behavioural response of Triatoma pseudomaculata to chemical substances present in their faeces or cuticle (footprints) was analyzed. Groups of larvae were simultaneously exposed to a clean filter paper and to another paper impregnated with a chemical stimulus in a circular arena. In these choice experiments, the insects aggregated significantly around papers impregnated with dry faeces. In ...

Three trials with torn bed nets impregnated with permethrin and deltamethrin were made under field conditions at the Soumousso Field Station and the Vallée du Kou rice-field area, both in Burkina Faso, and the Djoumouna fish pond area in the Congo Republic. Even a considerably torn correctly impregnated bed net could be an useful method for limiting human-anopheline contacts. But bed nets in po...

Dear Editor, Antibiotic-impregnated bone cement has been used routinely in total hip and knee replacements as it has been shown to reduce the incidence of deep wound infection.1-7 The antibiotics used include nephrotoxic gentamicin as well as tobramycin and polymyxin, besides other less nephrotoxic such as cefuroxime. The risk of nephrotoxicity from the use of the former has been deemed to be l...

For more than a century the Golgi method has been providing structural information about the organization of neuronal networks. Recent developments allow the extension of the method to the electron microscopic analysis of the afferent and efferent synaptic connections of identified, Golgi-impregnated neurones. The introduction of degeneration, autoradiographic, enzyme histochemical, and immunoc...

A unidimensional Thin Layer Chromatography system for the separation of salicylic acid and its derivatives (sulfosalicylic acid and Aspirin) has been developed. The separation was successfully using a solvent system of chloroform-methanol-water-ammonium hydroxide 120:75:6:2 (V/V) as mobile phase on TLC plates impregnated with boric acid. The method is based on different behavior of investigated...

Multiwall carbon nanotubes (CNTs) and iron oxide impregnated carbon nanotubes (CNTs-iron oxide) were investigated for the adsorption of hazardous toluene and paraxylene (p-xylene) from aqueous solution. Pure CNTs were impregnated with iron oxides nanoparticles using wet impregnation technique. Various characterization techniques including thermogravimetric analysis, scanning electron microscopy...

The antimicrobial-impregnated central venous catheter (CVC) has been the most intensively studied technology for the prevention of CVC-related bloodstream infections (BSIs) over the past 30 years. Although more than a dozen randomized trials have shown significant benefit, authors of an analysis published in a recent issue of Clinical Infectious Diseases have raised questions about the efficacy...
