Human Erythrocyte Ghost

Spectrin is a membrane associated protein most of which properties have been tentatively elucidated. A main role of the protein has been assumed to give a supporting structure to inside of the membrane. As reported previously, however, the isolated spectrin molecule underwent self assemble to form such as fibrous, meshwork, dispersed or aggregated arrangements depending upon the buffer suspended and was suggested to play an active role in the membrane conformational changes. In this study, the role of spectrin and actin was examined in terms of the molecular arrangements on the erythrocyte membrane surface with correlation to the functional states of the ghosts.Human erythrocyte ghosts were prepared from either freshly drawn or stocked bank blood by the method of Dodge et al with a slight modification as described before. Anti-spectrin antibody was raised against rabbit by injection of purified spectrin and partially purified.

Hardened Cement Paste

It has been almost universally adopted that dissolution of solids proceeds with development of uniform, continuous frontiers of reaction.However this point of view is doubtful / 1 /. E.g. we have proved the active role of the block (grain) boundaries in the main phases of cement, these boundaries being the areas of hydrate phases' nucleation / 2 /. It has brought to the supposition that the dissolution frontier of cement particles in water is discrete. It seems also probable that the dissolution proceeds through the channels, which serve both for the liquid phase movement and for the drainage of the incongruant solution products. These channels can be appeared along the block boundaries.In order to demonsrate it, we have offered the method of phase-contrast impregnation of the hardened cement paste with the solution of methyl metacrylahe and benzoyl peroxide. The viscosity of this solution is equal to that of water.

Sperm of decapod crustaceans are formed by a round or cup-shaped body, a complex acrosome and one a few appendages emerging from the main body. Although this sperm does not have motility, it has some components of the cytoskeleton like microtubules, which are found inside the appendages. Actin filaments have been found in the spike of penaeidae sperms. The actual participation of the crustacean decapod sperm cytoskeleton during fertilization is not well understood. Actin is supposed to play an active role in drawing the penaeidae shrimp sperm closer to the egg after bending of the spike. The present study was aimed at the localization of actin filaments in sperm of the Robinson Crusoe island lobster, Jasus frontalis and in the crayfish Orconectes propincus, by fluorescent probes and low voltage scanning electron microscopy.

Observer Agreement

Groups of undergraduate and graduate stndent listeners identified the stutterings and disfluencies of eight adult male stutterers during videotaped samples of their reading and speaking. Stuttering and disfluency loci were assigned to words or to intervals between words. The data indicated that stuttering and disfluency are not two reliable and unambiguous response classes and are not usually assigned to different, nonoverlapping behaviors. Furthermore, judgments of stuttering and disfluency were distributed similarly across words and intervals. For both undergraduate and graduate student listeners, there was relatively low unit-by-unit agreement among listeners and within the same listeners from one judgment session to another.

Suprasegmental Cues

This paper presents a case study of a language-impaired child who signaled the distinction between English singular and plural using suprasegmental cues rather than the usual segmental form used within the parent language. Acoustic analyses performed within the first study in the paper revealed that the suprasegmental features used to maintain this distinction included various duration, fundamental frequency, and intensity parameters. Acoustic analyses Were also performed on a set of matched two- and four-item plural forms within a second study. The results of these analyses indicated that the same acoustic parameters were used to distinguish two-item plural forms from four-item plural forms. This case of linguistic creativity is offered as further evidence in support of the model of language acquisition that emphasizes the active role children take in the acquisition process. Additionally, the phonological, morphological, and psycholinguistic factors that may contribute to such rule invention are discussed.

A graduate-level course in dysphagia is an integral part of the graduate curriculum in speech-language pathology. There are many challenges to meeting the needs of current graduate student clinicians, thus requiring the instructor to explore alternatives. These challenges, suggested paradigm shifts, and potential available solutions are explored. Current trends, lack of evidence for current methods, and the variety of approaches to teaching the dysphagia course are presented.

While the use of vinegar to fi ght against infections and other crucial conditions dates back to Hippocrates, recent research has found that vinegar consumption has a positive effect on biomarkers for diabetes, cancer, and heart diseases. Different types of vinegar have been used in the world during different time periods. Vinegar is produced by a fermentation process. Foods with a high content of carbohydrates are a good source of vinegar. Review of the results of different studies performed on vinegar components reveals that the daily use of these components has a healthy impact on the physiological and chemical structure of the human body. During the era of Hippocrates, people used vinegar as a medicine to treat wounds, which means that vinegar is one of the ancient foods used as folk medicine. The purpose of the current review paper is to provide a detailed summary of the outcome of previous studies emphasizing the role of vinegar in treatment of different diseases both in acute and chronic conditions, its in vivo mechanism and the active role of different bacteria.

Social Identity Development

Entering a new group provides the potential of forming a new social identity. Starting from self-regulation models, we propose that goals (e.g., internal motivation to enter the group), strategies (e.g., approach and avoidance strategies), and events (e.g., the group’s response) affect the development of the social self. In two studies we manipulated the group’s response (acceptance vs. rejection) and assessed internal motivation as well as approach and avoidance strategies. It was expected, and we found, that when newcomers are accepted, their use of approach strategies (but not avoidance strategies) facilitates social identification. In line with self-completion theory, for highly internally motivated individuals approach strategies facilitated social identification even upon rejection. The results underline the active role of newcomers in their social identity development.
