When talking about the importance of education, M.  Lukšienė emphasizes that in order to understand and master the process of education educators must be familiar with laws that dominate the world of an individual and his environment. The article presents the results of a spoken language analysis of children who grow in infants’ homes, in a specific environment of care and educational institutions for young children. It highlights some of the pragmatic, semantic, phonological and morphological characteristics of the children’s language. The article moreover presents linguistic self-expression levels and peculiarities of young children identified during the analysis of the corpus of language of children from specific environments and the possibilities of comprehending language elements and functions. Object of the research: expression of spoken language of children from infants’ home. The aim of the research is to analyze peculiarities of spoken language of children from infants’ home. Research methods: analysis of scientific literature on the peculiarities of children’s language use at an early age, empirical observation of a child, analysis of the peculiarities of spoken language (understanding and use), comparative empirical analysis, that allow for presenting educational statements relevant to the language of young children. Subjects of the research: 157 pupils from infants’ home. Research results: this research was an attempt to analyze spoken language data of young children from the Lithuanian infants’ homes obtained by means of observation only. The research of peculiarities of the speech of children from the infants’ homes on a phonological level revealed that the overall ability of young children to articulate sounds in the Lithuanian language is to be considered only satisfactory, inasmuch as only 4 out of 30 young children are able to pronounce nearly all the sounds and the speech of most of the children is distinguished by an abundance of phonemic errors: this means replacement of difficult – to - pronounce sounds with other sounds, omission, shortening of words, confusing sounds with similar articulation, extension, incorrect pronunciation of soft and hard phonemes, failure to pronounce and replacing vowels, monophthongization of diphthongs and diphthongization of a long mid vowel “ė”, errors in shifting from one sound to another, distortion of sound / syllabic word structure, etc. The research of grammar (morphology) of speech of children from the infants’ homes led to the conclusion that children from the infants’ homes do not know or confuse generalizing terms, do not know their individual names. Thy moreover have little knowledge of colors. These children use one verb to identify similar actions. Nouns in the speech of children from the infants’ homes usually are names of clothing, body parts and performers of actions. Children communicate using words with a constant meaning, understand some of the grammatical forms; however, they sometimes fail to identify the quantity of nouns and prefer singular form. There are almost no adjectives in an independent speech. Children make errors when using verb forms, for example, use infinitive form instead of one of the other forms. In addition to names of objects, actions and properties, uninflected parts of speech occur: prepositions, adverbs, conjunctions, etc. Children also differentiate between interrogatives. Children from the infants’ homes are already able to answer questions, while looking at pictures. However, they do not understand consistent patterns of direct control and intensely confuse declensional forms with each other. They skip, interchange prepositions and pronounce them inaccurately.

During the almost 50 years since Streptococcus mutans was first suggested as a factor in the etiology of dental caries, a multitude of studies have confirmed the cariogenic potential of this organism. Streptococci have been isolated from human and animal caries on numerous occasions and, with few exceptions, they are not typable by the Lancefield technique but are relatively homogeneous in their biochemical reactions. An analysis of the guanine-cytosine (G-C) composition of the DNA from strains K-1-R, NCTC 10449, and FA-1 by one of us (ALC) revealed significant differences and DNA-DNA reassociation experiments indicated that genetic heterogeneity existed among the three strains. The present electron microscopic study had as its objective the elucidation of any distinguishing morphological characteristics which might further characterize the respective strains.

A Cell

A cell line, UC1-B, which was derived from Balb/3T3 cells, maintains the same morphological characteristics of the non-transformed parental culture, and shows no evidence of spontaneous virus production. Survey by electron microscopy shows that the cell line consists of spindle-shaped cells with no unusual features and no endogenous virus particles.UC1-B cells respond to Moloney leukemia virus (MLV) infection by a change in morphology and growth pattern which is typical of cells transformed by sarcoma virus. Electron microscopy shows that the cells are now variable in shape (rounded, rhomboid, and spindle), and each cell type has some microvilli. Virtually all (90%) of the cells show virus particles developing at the cell surface and within the cytoplasm. Maturing viruses, typical of the oncogenic viruses, are found along with atypical tubular forms in the same cell.

Reliable Marker

Apoptosis, or programmed cell death, is an important mechanism in development and in diverse disease states. The morphological characteristics of apoptosis were first identified using the electron microscope. Since then, DNA laddering on agarose gels was found to correlate well with apoptotic cell death in cultured cells of dissimilar origins. Recently numerous DNA nick end labeling methods have been developed in an attempt to visualize, at the light microscopic level, the apoptotic cells responsible for DNA laddering.The present studies were designed to compare various tissue processing techniques and staining methods to assess the occurrence of apoptosis in post mortem tissue from Alzheimer's diseased (AD) and control human brains by DNA nick end labeling methods. Three tissue preparation methods and two commercial DNA nick end labeling kits were evaluated: the Apoptag kit from Oncor and the Biotin-21 dUTP 3' end labeling kit from Clontech. The detection methods of the two kits differed in that the Oncor kit used digoxigenin dUTP and anti-digoxigenin-peroxidase and the Clontech used biotinylated dUTP and avidinperoxidase. Both used 3-3' diaminobenzidine (DAB) for final color development.

Oreochromis mossambicus is currently receiving much attention as a candidater species for aquaculture programs within Southern Africa. This has stimulated interest in its breeding cycle as well as the morphological characteristics of the gonads. Limited information is available on SEM and TEM observations of the male gonads. It is known that the testis of O. mossambicus is a paired, intra-abdominal structure of the lobular type, although further details of its characteristics are not known. Current investigations have shown that spermatids reach full maturity some two months after the female becomes gravid. Throughout the year, the testes contain spermatids at various stages of development although spermiogenesis appears to be maximal during November when spawning occurs. This paper describes the morphological and ultrastructural characteristics of the testes and spermatids.Specimens of this fish were collected at Syferkuil Dam, 8 km north- west of the University of the North over a twelve month period, sacrificed and the testes excised.

A controversial topic in the study of structure-property relationships of toughened polymer systems is the internal cavitation of toughener particles resulting from damage on impact or tensile deformation.Detailed observations of the influence of morphological characteristics such as particle size distribution on deformation mechanisms such as shear yield and cavitation could provide valuable guidance for selection of processing conditions, but TEM observation of damaged zones presents some experimental difficulties.Previously published TEM images of impact fractured toughened nylon show holes but contrast between matrix and toughener is lacking; other systems investigated have clearly shown cavitated impact modifier particles. In rubber toughened nylon, the physical characteristics of cavitated material differ from undamaged material to the extent that sectioning of heavily damaged regions by cryoultramicrotomy with a diamond knife results in sections of greater than optimum thickness (Figure 1). The detailed morphology is obscured despite selective staining of the rubber phase using the ruthenium trichloride route to ruthenium tetroxide.
