Background and Aim Acanthamoeba is one of free-living amoebas, which are very abundant in nature. As a amoeba, this parasite has high lethality, especially people with underlying diseases, so researchers always looking for way to combat it. Drug plants good fight species. In study, we aimed investigate the lethal effect extract Oliveria decumbens vent Peganum harmala alcoholic on Acanthamoeba. ...

The concept of the unconscious plays a fundamental part in many psychological systems, although as its very name indicates it is defined more by what it is not than by what it is. And yet, the unconscious as a systematic concept is not synonymous with the non-conscious. Rather does the existence of an unconscious presuppose the existence, potential or actual, of a conscious. The movements of a ...

Syntaxin-1 and 25-kDa Synaptosome-associated Protein (SNAP-25) are present in the plasma membrane of several different secretory cell types and are involved in the exocytosis process. In this work, the free-living amoeba Difflugia corona was studied in relation to ultrastructure, structural membrane proteins, and proteins such as Syntaxin-1 and SNAP-25. Our results obtained by scanning electron...

1. Protein fractions derived from tubercle bacilli are toxic to the interior of Amoeba dubia but have no action on the plasmalemma. 2. Phosphatide fractions dissolve the plasmalemma but have no effect on the internal cytoplasm. 3. The fatty acid fraction has a marked solvent action on the plasmalemma when brought in contact with the surface of the cell. When injected it may slowly penetrate the...

O -line clock synchronisation algorithms, in which synchronisation is performed by adjusting a collection of recorded timestamps, is suitable for use with many monitors for distributed systems. O -line synchronisation can often achieve very good synchronisation without the need for extra messages. The work described here builds on earlier work in this area [4] by introducing new synchronisation...

The Amoeba group communication system has two unique aspects: (1) it uses a sequencer-based protocol with negative acknowledgements for achieving a total order on all group messages; and (2) users choose the degree of fault tolerance they desire. This paper reports on our design decisions in retrospect, the performance of the Amoeba group system, and our experiences using the system. We conclud...

Acanthamoeba are abundant in a wide range of environments, and some species are responsible for cutaneous infections, keratitis, and granulomatous amoebic encephalitis (GAE). The conventional detection and isolation of amoeba from clinical and environmental samples involves sampling and culture on non-nutrient Ágar medium. Although efficient, this system requires several transfers in order to e...

medicina fluminensis 2016, Vol. 52, No. 1, p. 49-54 49 Abstract. free-living amoebae are present in the nature, feeding mainly with bacteria, fungi, and algae. Some microorganisms have evolved different mechanisms to resist the digestion by amoebae and they are called “amoeba-resistant microorganisms”. Some of the important human bacterial pathogens belong to this category including Cryptococcu...

1. The respiration of Amoeba proteus was measured. 10 c. mm. of cells were found to use about 1.6 mm.(3) of oxygen per hour at 20 degrees C. The respiratory quotient was found to be nearly unity. 2. No anaerobic metabolism was found for Amoeba. 3. The respiration of Blepharisma was found to be from 3 to 7 mm.(3) oxygen per hour for 10 mm.(3) cells. The respiratory quotient was about 1. 4. Bleph...
