Chemical dissolution and in vitro studies of 2-day old chick embryo notochordal cells, 1964
No full textThis study was undertaken. to determine the behavioral pattern of dissociated 2-day old chick notochordal. cells in vitro. Notochords were dissected from embryos that had been incubated for 48 hours (1820 somites) at 37.50 degrees celsius and complete ly dissociated in a 2% tetrasodium ethylene diamine tetra acetic acid/calcium and magnesiumfree NiuTwitty- solution. Pieces of notochordal tissue and dissociated cells were separately cultured in a fluid medium (1% dextrose/ca1cium~ and magnesium-.free NiuTwitty solution) by the lying drop single coverslip technique. Extensive outgrowth from the explant, cell division, and changes in cell shape were Observed in the cultured tissue fragments. The dissociated cells in culture aggregated to form clumps that possessed loose cell attachments. No cell division or noticeable change in cell shape, however, occurred in these cells. It was concluded in light of these observations that calcium and/or magnesium are intimately involved in the role of cell adhesion in the 2day old chick notochord. Also, a 1% dextrose/calcium- and magnesiuium-free culture medium does not support mitotic activity of single notochordal cells of the same age
The impact of indivualized counseling with a woman diagnosed with major depression, 1996
Get PDFThe study examined different intervention approaches to treating Major Depression. The study was based on the premise that a combination of different approaches would be as or more effective than simply using one treatment approach.The purpose of this study was to utilize individualized counseling as a treatment approach to decrease depressive symptoms in a woman diagnosed with Major Depression. One standardized measure was administered, the Generalized Contentment Scale. The intervention period lasted five months and consisted of individualized counseling provided by the client's therapist. The client answered the questionnaire after each individual session. The results showed a minimal increase in general contentment within a five month intervention phase. The conclusion drawn from these findings suggests that factors other than individualized counseling should be considered as key elements in treating a patient with Major Depression. Those factors, both internal and external, include looking at the patient s social history and situation, family environment, cultural environment, physical health, social motivation and free will. This will help not only provide a more accurate diagnosis, but also a more effective intervention to cure targeted symptoms
A descriptive study of the relationship between lifestyle and economic self-sufficiency among single female heads of household residing in public housing and non-public housing, 1995
Get PDFThis research was to examine the relationship between lifestyle and economic self-sufficiency among single female parents and whether their lifestyle increased their ability to be economically self-sufficient. Economic self-sufficiency was operationalized as the ability to maintain oneself without the need of income assistance from Aid to Families with Dependent Children and motivated to accomplish life goals. Lifestyle was defined by career/life goals, personal values, socio-political orientation, and self-concept. The research utilized the learned helplessness theory to explain dependent behavior and perceptions. This related to the long-term welfare recipients dependence on government assistance. The findings revealed no correlation between economic self-sufficiency and lifestyle. There was statistically significant differences in the two groups of single female heads of household. Public housing respondents had a more postive response to career life goals than non-public housing repsondents thus indicating a desire to reach higher goals yet having an inability to actualize those goals
Ja und nein': a study of the effects of parental attitudes in contributing to the development of the superego of thirty patients, ages five through seventeen, diagnosed as neurotic or having primary behavior disorders at the children's center of metropolitan Detroit from May 12, 1947 to December 14, 1951

Studies on the nodal structure and leap trace development in the genus ulmus, 1978
Get PDFAn exploratory study on the histological appearance of nodal structure and leaf trace development has been made from paraffin section of elm twigs. The nodal vasculature of primary growth in genus Ulmus is extremely varied between elm species, and at different nodes of twigs of the same species. This study has attempted to carry out a critical investigation of the nodal structure with its leaf trace development in several species, involving both the resistant and susceptible ones. The significant nodes in elm trees are structurally associated with eccentric buds and petioles of leaves in reference to twigs by the relationship of their vasculature. This primary growth applied to the node is a structural union of petiole and stelar vascular supply. The feature of conductive vascular system is the so-called leaf traces, which depart from the stele to the leaf, or conversely enter the stem from the petiole, and which have been revealed and characterized in the nodal structure.For U. americana or some other elm species, the median traces were found to be divided and, when they approached the petiole, either of two lateral traces was undulating in nature at a node. The undulating lateral trace would emerge at high or low levels in the stem where it occurred closely in associa-tion with the median trace at the stele. With the result of occurrence and position of axillary bud, some variations in lateral trace features are noted to differ between species. By the differentiation of tracheary elements in leaf traces, the metaxylem in the outermost zone of leaf trace differentiates tangentially in continuity with the early-formed protoxylem. Of the pattern of tracheary element organization in leaf trace, the average number of parenchyma cells intercalated between the variable number of vessel rows has revealed that a significant relationship of vessel member features in parenchyma-tracheary elements is found to differ between species. However, as compared among the nine species of elm trees in their leaf traces, several significant differences in anatomical structure were noted. The tracheary elements of leaf trace are really one thing of importance but, as a matter of fact, the development of leaf trace is something else
