The Relationship Among Maternal Characteristics, Maternal Dietary Self-Regulation, And The Dietary Intake And Body Weight Status Of Two To Five-Year-Old Children, Andrea Bushaw

Dissertations

Eating preferences and practices are established early in life, yet we have little knowledge about how mothers make food decisions on behalf of their children. These decisions, however, lay the foundation for their child's lifelong food preferences and eating behaviors. Almost one-third of all children in the U.S. are overweight or obese putting them at high risk for becoming an overweight or obese adult. To make a difference in the ongoing obesity epidemic, we must better understand the relationship among characteristics of the mother who controls the young child's access to food, food choices, and feeding practices. This knowledge will …

Cell Size Control Mechanisms In The Multiple Fission Cell Cycle Of Chlamydomonas, Dianyi Liu

Dissertations

Size homeostasis is achieved by a balance between cell growth and cell division, but the underlying mechanisms are yet fully understood. Green alga Chlamydomonas reinhardtii (Chlamydomonas) is a unique model for size control. Instead of the canonical binary fission cell cycle, Chlamydomonas uses a multiple fission cell cycle where a prolonged G1 phase is followed by rapid alternative n rounds of S/M (DNA synthesis and mitosis) cycles to produce 2ⁿ daughter cells. Two size checkpoints show size-dependence: the Commitment checkpoint governs a minimum size for a cell to divide at least once, and the S/M checkpoint governs the division …

Investigations Of The Potential Use Of Macrophages In Gastric Stem Cell Activation/Differentiation And Ulcer Healing, Subi Sugathan

Dissertations

Stomach erosions and ulcerations are common health problems, and their therapy requires tissue regeneration. While current therapy for these disorders focuses on targeting parietal cells to inhibit acid secretion, the role of stem cells in the regeneration process is neglected. In this study, the aim is to investigate the potential use of macrophages to activate gastric stem cells in co-culture experiments and in a mouse model of gastric ulcer. Bone marrow-derived macrophages were prepared and cultured in the presence of lipopolysaccharides and interleukin-4 to, respectively, induce their differentiation into pro-inflammatory (M1) and anti-inflammatory (M2) macrophages. Polarization of these phenotypes was …

Personality And Psychopathology Correlates Of Institutional Misconduct Among Juvenile Offenders, Paula Floyd

Dissertations

Juvenile delinquency is a national concern, as delinquent behavior is associated with a host of poor psychosocial outcomes during later adolescence and adulthood. To address delinquency, it is important to understand psychological adjustment among adolescents who have already made contact with the juvenile justice system. One way to explore adjustment within this population involves examining personality and psychopathology correlates of institutional misconduct (i.e., behavioral infractions while incarcerated). While there is a robust body of literature regarding personality and psychopathology correlates of misconduct in adult inmate samples, there has been far less work devoted to these relationships among justice-involved youth. Furthermore, …
