a case who was suffering from abdominal pain and chronic diarrhea refered to isfahan health training and research center, institute of public health. current treatments for chronic diarrhea incloding a traial of gluten fre diet were performed but these were not effective because he was infected by dicrocoelium dentriticum. then he was cured with parasitic treatment.

Group-specific polysaccharides of Neisseria meningitidis groups A and C have been demonstrated by means of a rapid, sensitive slide agglutination test with latex particles coated with antibodies. In this manner, the diagnosis can be made from the cerebrospinal fluid of patients with meningococcal meningitis caused by serogroups A or C even when the culture is negative. The method appears to be ...

An immunocapture reverse transcription polymerase chain reaction (IC-RT-PCR) method for a highly sensitive analysis of raspberry bushy dwarf virus (RBDV) in infected plants is described. In the method, preliminary purification of virus particles or viral RNA from the plant material is not necessary. Viruses are enriched during the assay by antibodies bound in the PCR microplate wells, followed ...

The photoelectric smoke detector shows different levels of sensitivity to different fire types. The photoelectric detector generally is more sensitive to the gray smoke emitted by smoldering fires, and less sensitive to the black smoke emitted by flaming fires. To improve such a photoelectric detector, the light scattering phenomena by smoke particles have been studied, and numerical simulation...

The Dust Detector System onboard Galileo records dust impacts in the Jupiter system. Impact events are classified into four quality classes. Class 3 – our highest quality class – has always been noise-free and, therefore, contains only true dust impacts. Depending on the noise environment, class 2 are dust impacts or noise. Within 20 R J from Jupiter (Jupiter radius, R J = 71, 492 km) class 2 s...

pH-Sensitive poly(N,N-dimethylaminoethyl methacrylate (DMAEMA)/2-hydroxyethyl methacrylate (HEMA)) nanoparticles were prepared for the triggered release of paclitaxel within a tumor microenvironment. Tumors exhibit a lower extracellular pH than normal tissues. We show that paclitaxel release from DMAEMA/HEMA particles can be actively triggered by small, physiological changes in pH (within 0.2-0...

Despite considerable popularity, the mechanisms that govern the behavior of Particle Swarm Optimization (PSO) are still a subject of research. Regarding communication between particles, for example, many authors have discussed the effects of swarm topology, but few have studied the dynamics of the information exchange among particles. In this paper we show that a synchronous update of the socia...

Changes in electric parameters of a mesoporous silicon treated by a plasma chemical etching with fluorine and hydrogen ions, under the adsorption of NEPO (Nematodetransmitted Polyhedral) plant viruses such as TORSV (Tomato Ringspot Virus), GFLV (Grapevine Fan Leaf Virus) and protein macromolecule from TORSV particles are described. The current response to the applied voltage is measured for eac...
