The Developmental Timing of Divorce and Adult Children's Romantic Relationship Quality
… adult offspring, less known is about whether the timing of divorce influences the relationship outcomes of adult children. Using a large nationally representative sample in terms of race (N=6,066), eight groups of individuals (males and females from intact homes, males and females who experienced …

Genetic diversity, developmental timing, and physiological efficiency for climate-resilient maize
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2026-05-01

Comparative studies of brain developmental timing and progression using 3D stem cell models
… of different origins with potentially different developmental tempos, and also provide evidence that the self-organising nature of differentiation under the protocol means that developmental timings are cell line intrinsic and largely unconfounded by species-specific adaptations to the protocol …

Developmental timing of pupation and analysis of color pattern response to thermal stress in Bombus impatiens (Hymenoptera: Apidae)
… on late instar larvae to determine whether developmental temperatures alter adult color pattern phenotypes. I selected a species that is monomorphic in color pattern, Bombus impatiens, and demonstrated that individuals are able to withstand a wide range of temperatures and retain their …

Functional analysis of the microRNA genes of C. elegans
… in C. elegans during studies of the control of developmental timing. MicroRNAs are a large class of short non-coding RNAs found in many viruses, plants and animals that regulate gene expression through sequence-specific base-pairing with target mRNAs. Initial studies since the identification of …

The Effect of Mindfulness on Adolescent Self-compassion, Self-regulation, and Stress: Exploring the Association Between Individual Factors and Markers of Well-being
… those variables that are associated with gender, developmental timing, and extraversion/surgency. Results indicated that participation in the Inner Strength Teen Program may promote self-compassion, reduce rumination, and increase involuntary action. Significant changes were not found in …

FOXO is the Mediator Linking Temporal Differentiation and the Insulin Signaling Pathway
The timing of differentiation is crucial for the correct development of an organism, because specific pathways can be used reiteratively to differentiate cells. Until recently, the molecular mechanism behind the temporal control of differentiation has remained elusive. Bateman and McNeill (2004) …

The function of chromatin regulators during patterning and growth in Drosophila wing disc regeneration
… PBAP complex regulates regenerative growth and developmental timing, and is required for the expression of JNK signaling targets and the growth promoter Myc. By contrast, the BAP complex is required for ensuring proper patterning and cell fate by stabilizing the expression of the posterior gene …

Computational prediction of RNA-based gene regulatory mechanisms in human and Tetrahymena
… such as genomic rearrangement in ciliates and developmental timing and tissue differentiation in plants and animals. Here we present a computational study into the function of two distinct classes of sRNAs. In the first section, we examine an uncharacterized class of sRNAs isolated from the …

Identification, Characterization, and Abiotic Stress Analysis of microRNAs in Nicotiana tabacum
… in plants by regulating growth and development, developmental timing, hormone signaling, organogenesis, and response to environmental stresses. Based on the conservation of mature miRNA sequences, computational methods have been used to predict thousands of miRNAs in numerous plant species, such …

Silencing the host : the role of intronic microRNAs
… but interfering RNA structure involved in developmental timing in C. elegans. First thought not, or only rarely, to occur in mammals, microRNAs are now among the major players in up-to-date genomic research. The mature molecules are ~22 nucleotides in length and, by targeting predominantly …

EARLY-LIFE DEVELOPMENT OF ANTIPREDATOR BEHAVIOUR OF JUVENILE NORTHERN CRAYFISH (FAXONIUS VIRILIS)
… antipredator associations, potentially due to developmental constraints or insufficient reinforcement during early life. Together, these results highlight the importance of developmental timing and cue reliability in shaping antipredator behaviour in aquatic organisms.

The Functional Roles of the Lin28/let-7 Axis in Tissue Regeneration and Cancer
… their initially discovered role in controlling developmental timing, or heterochrony. Subsequent studies have further uncovered many additional cellular processes, such as differentiation, metabolism, and body size, controlled by Lin28 and let-7. Their role in pathology, however, is not as well …

The Function and Mechanism of RNA Interference in Neurospora
… for various biological processes, including developmental timing, genome defense, and heterochromatin formation. RNAi is triggered by double stranded RNA (dsRNA), which is processed by Dicer to siRNA. siRNA is loaded onto RNA-induced silencing complex (RISC), in which an Argonaute family …

Molecular Mechanisms Controlling the Development and Evolution of the Human Cerebral Cortex
… enabling the characterisation of cell-autonomous developmental mechanisms, comparative studies with more closely related species, and experimental testing of hypotheses on gene function and regulation. In the work presented here, I firstly examine the pathways that specify the generation of …

A New Type of Programmed Cell Death in C. Elegans
… investigate this question, we have studied the developmentally regulated PCD of the Caenorhabditis elegans linker cell. We have carried out transmission electron microscopy studies of dying linker cells, which revealed non-apoptotic features, including nuclear crenellation in the absence of …

Characterization of Transcriptional and Post-transcriptional Regulation of lin-42/Period During Post-embryonic Development of C. elegans
… conserved in metazoans, regulates circadian timing of neurophysiology as well as cell fate specification. Studies in mouse and humans indicate that period functions as a tumor suppressor and controls adult stem cell differentiation. However, regulation of period function in developmental …

Pluripotency and patterning in nonhuman primate embryogenesis
… differs in anatomical architecture, developmental timing, and molecular configuration. Obvious ethical considerations limit human embryo research, thus nonhuman primates offer an opportunity to unravel primate-specific features of pluripotency. This thesis examines common marmoset …

Familiar Food-Induced Feeding Activation in C. Elegans
… on duration of exposure to food to learn but not developmental timing of exposure or nutritional status. Furthermore, worms could remember the previously experienced food at least for several hours. My study provides insight into how feeding organ operates to increase food intake in response to …

Trauma Exposures Across the Life Course for Individuals Who Experience Incarceration
… the types of trauma exposures and the developmental timing of the trauma exposures experienced by incarcerated individuals, especially men, as most trauma research to date has focused on incarcerated women. In order to develop appropriate interventions that increase the likelihood that …
