Removal of Cu(II) from aqueous solution supplies is possible through the process of adsorption. One of these processes involves the preparation of magnetic nanoparticles on activated carbon (AC). Adsorbed coppre ions on the surface of Fe3O4-AC are separated from aqueous solutions using external magnetic fields. In the present study, magnetic nanoparticles were synthesized ...

the pharmacokinetics of cefpirome was investigated in buffalo calves following its single intramuscular (im) administration (10 mg). the peak plasma concentration of cefpirome at 30 min was 9.0 ± 0.5 μg.ml-1, which declined to 0.2 ± 0.1 μg.ml -1 at 24 hrs. the absorption half-life (t1/2ka) and elimination half-life (t1/2 β) were 0.19 ± 0.03 hr and 2.39 ± 0.05 hr, respectively. the area under th...

This paper presents a kinetic model of the laccase-aided chlorine dioxide bleaching of bagasse pulp. The kinetic model was based on the rate of reduction of adsorbed organic halogen (AOX). The effects of the laccase enzyme dosage, the mediator 1-hydroxybenzotriazole (HBT) dosage, and the reaction temperature on the AOX content of the bleaching effluent are discussed. Good fits were obtained for...

In order to enhance mechanical dewatering, conditioning polymers are used to flocculate sewage sludge. These polymers modify floc structure, which has an impact on dewatering efficiency. However, fundamental aspects of those processes are incompletely understood, particularly the way that flocs are structurally organized and how this may relate to their mechanical and dewatering properties. Thu...

BACKGROUND Most patients who use insulin do not achieve optimal glycemic control and become susceptible to complications. Numerous clinical trials have shown that frequent insulin dosage titration is imperative to achieve glycemic control. Unfortunately, implementation of such a paradigm is often impractical. We hypothesized that the Diabetes Insulin Guidance System (DIGS™) (Hygieia, Inc., Ann ...

In this study the feasibility of preparing bioflocculant from excess biological sludge was investigated. Hydrochloric acid was used to disintegrate sludge to prepare bioflocculant. The effects of acid dosage and flocculating conditions were studied. The optimized disintegration conditions was that acid dosage was 10 mL for 50 mL sludge suspension. Factors such as bioflocculant dosage, pH and te...

The most important limitation associated with the clinical use of cyclosporine is the narrow therapeutic range between its efficacy and toxicity. Effective treatment is further complicated by significant variation in intrapatient and interpatient pharmacokinetics of the drug. We describe a practical approach to pharmacokinetic analysis that does not interfere with the cyclosporine dosage regime...

Strategies involving new applications of existing drugs are urgently needed to reduce the time required to cure patients with drug-susceptible and drug-resistant tuberculosis (TB). Use of high-dosage rifampicin is one such approach. Recent data from preclinical animal models (Hu et al., 2015) and clinical studies (Boeree et al., 2015) support a potential role for highdosage rifampicin in TB che...

Imatinib, the first-line treatment in patients with advanced gastrointestinal stromal tumors (GIST), is generally well tolerated, although some patients have difficulty tolerating the standard dose of 400 mg/day. Adjusting imatinib dosage by plasma level monitoring may facilitate management of patients who experience intolerable toxicities due to overexposure to the drug. We present two cases o...

This paper presents the degradation of phenol in wastewater using anolyte, which is generated from electrochemical activation process. Anolyte consists of reactive ions and free radicals, which contribute to its oxidizing behavior. The optimum conditions, which facilitate a complete degradation of phenol, were found using variation of dosage of anolyte and reaction time. It was found that about...
