In recent years, the occurrence and fate of antibiotics in the aquatic environment have been the subjects of many investigations in several countries. Tetracyclines (TCs) comprise an important group of pharmaceuticals in today's human and veterinary medical practice. However, they undergo slow degradation and transformation in the aquatic environment. The removal of tetracycline (TC) and oxytetracycline (OTC) from synthetic solutions ...
Proceedings of the 17th Southern Biomedical Engineering Conference, 1998
In this paper, a model to reflect the immunological properties of white blood cells is created. White blood cells kill infectious bacteria. Two kinds of white blood cells - CHO-IIA and THP1 are studied. Bacteria of sizes 5mum and 0.05mum, and an amount of catalytic agent MbetaCD is added to the white blood cell. Experiments are conducted first by keeping the bacteria size fixed and varying the amount of MbetaCD to observe their effects on bacteria bound to a cell, and then bacteria internalized by a cell. Later the same experiment is repeated with a different bacteria size. The data collected is used to create a model with inbuilt rules, based on fuzzy logic. The model is trained with back propagation using neuro-fuzzy techniques, in order to improve the model. The results obtained by the model are compared with the actual observed data to compare the efficiency of the model. With training, the Root Mean Squared Error reduced from 0.4099 to 0.3705. Complete software with a Graphical User Interface is built to easily display the output of the model, from user-given input.
This paper presents a symmetric three-flow microfluidic concentration gradient generator, made possible by a 3D microchannel network fabricated via ultra- high resolution Multijet 3D printing. The prototype fluidic device is utilized as an effective tool for the expedited screening of multi-drug combinations. It rapidly generates 15 discrete combinations of three input drugs which are used to determine the minimum inhibitory concentration (MIC) value of the three individual antibiotics, as well as to perform simultaneous clinical three-way antibiotic interaction studies on ampicillin-resistant Escherichia coli (E. coli) bacteria. The results from individual antibiotic experiments are used to determine the discrete MIC values, and the multi-drug study reveals clinically relevant antagonistic, synergistic and suppressive interactions between the three different families of antibiotics commonly used to combat antibiotic resistant infections. Furthermore, a simple and effective method of visual interpretation of the experimental results is employed, demonstrating this device's use as an effective multi-drug screening platform for applications in point-of-care biomedical research and clinical medicine.
This paper presents a case for an intelligent agent-based framework for knowledge discovery in a distributed healthcare environment comprising multiple heterogeneous healthcare data repositories. Data-mediated knowledge discovery, especially from multiple heterogeneous data resources, is a tedious process and imposes significant operational constraints on end-users. We demonstrate that autonomous, reactive and proactive intelligent agents provide an opportunity to generate end-user-oriented, packaged, value-added decision- support/strategic planning services for healthcare professionals and managers. We propose the use of intelligent agents to implement a distributed agent- based data mining information structure that provides a suite of healthcare- oriented decision-support/strategic planning services.
In recent years, the occurrence and fate of antibiotics in the aquatic environment have been the subjects of many investigations in several countries. Tetracyclines (TCs) comprise an important group of pharmaceuticals in today's human and veterinary medical practice. However, they undergo slow degradation and transformation in the aquatic environment. The removal of tetracycline (TC) and oxytetracycline (OTC) from synthetic solutions by a reverse osmosis membrane was studied. The effects of the operation parameters of the membrane, feed concentration and salinity were investigated on the removal of TCs. High removal efficiencies (>90%) were observed for TC and OTC with the RO membrane used. Removal efficiency of OTC by RO is a bit higher than TC.
In this paper, the occurrence and removal of eight fluoroquinolone antibiotics were investigated at a sewage treatment plant (STP) in Shanghai, China. The most frequently detected fluoroquinolone antibiotics in the present study were norfloxacin, ciprofloxacin and lomefloxacin. The concentrations of these compounds in water samples at the STP ranged from 103 to 1786 ng L<sup>-1</sup>, 14 to 1406 ng L<sup>-1</sup> and 21 to 2246 ng L<sup>-1</sup>, respectively. The other fluoroquinolone antibiotics were detected only in a few samples from the STP. FQs in aquatic phase could not be eliminated completely from the STP, with the removal efficiencies from 70% to 100%. The concentrations of FQs in water detected in summer were higher than in other seasons, due to the more desorption from sludge to aquatic phase under higher temperature.
As part of a larger on-going investigation to study the disease bartonellosis, remote sensing images are being used to map the study area and to help determine environmental factors that may influence the abundance of sand flies, the insect thought to be the vector of the disease. A plot of positive patient houses on a Landsat image shows that most of the cases occur in the agricultural areas and few cases occur in the town. The disease does not occur more frequently near the river. One of the classes produced from an unsupervised classification of a Landsat image occurs frequently with the positive houses and infrequently with the negative houses. Additional positive and negative houses are needed to confirm this result and future studies will attempt to determine what environmental factors are represented by the class and how these factors might relate to sand fly distribution.
Calcium apatite powder was formed and a definite quantity was mixed separately with 1% solutions of gelatin, chitosan and collagen to form a paste. The gelatin apatite mixture flowed easily while the collagen apatite one was too viscous. The paste formed by the different mixtures was packed individually in thin plastic tubes and calcined at 800/spl deg/C. The ashing away of the organic matter and the phase transformation of the phosphate resulted in rod shaped calcium phosphate rods. The chitosan apatite paste gave the most uniform rods of good porosity. The calcined samples were analysed for their chemical and physical properties. Characterisation was done by FT IR and X-ray diffraction. The material was stable in water and in a phosphate buffer and did not disintegrate. The water uptake and chitosan solution uptake were determined. The porous rods were brittle with comparatively poor bending strength. The apatite rods loaded with an antibiotic like gentamicin sulphate is intended to be used for drug delivery at the sites of orthopaedic implants for the prevention of osteomyelitis.
The introduction of foodstuffs, biologically active additives, animal feeds certification procedure requires development of express, high sensitive and accurate methods of determination of a number of chemical organic compounds. Vitamins and some flavonoids belong to alimentary organic substances required in small amounts. The antibiotics contained in foods and biologically active additives based on milk stuffs render toxic activity on human organism. One should pay attention on the high level of contaminating by chloramphenicol, streptomycin, tetracycline -the antibiotics with dangerous side - effects. The optimal conditions of quantitative chemical analysis antibiotics mentioned above, water- and liposoluble vitamins in foodstuffs and feeds, pharmaceuticals (powders, eye drops, tablets etc.) have been determined. The stage of preliminary isolation of determined substances at pretreatment before voltammetric measurements has been considerable simplified. The interference of water-soluble proteins has been eliminated by their hydrolysis, saponification and salting-out with organic solvents and salts. The designed methods allow to control the content of antibiotics, vitamins at levels of the demanded by the normative documents. The methods are certificated
For the prompt prescription of patients suffering from infectious diseases such as tuberculosis or bloodstream infection, a rapid antimicrobial susceptibility test (RAST) is highly necessary. This paper describe rapid antibiotic susceptibility test system composed of biochips and automated expert system, which can determine the antibiotic susceptibility of bacteria and mycobacteria derived from various parts of body. With RAST, antibiotic susceptibility was available in six hours, which was conventionally taking more than two days. Device design consideration, clinical verification, commercialization, and application of RAST system to infectious diseases are reviewed.
