Fundamental Rights And Fair Fights: Holding Out For Legal Patent Recognition Under State Multiparent Recognition Statutes, Heather Kolinsky Jun 2026

Fundamental Rights And Fair Fights: Holding Out For Legal Patent Recognition Under State Multiparent Recognition Statutes, Heather Kolinsky

Loyola of Los Angeles Law Review

This Article considers the impact of the behavioral proxy of holding out to establish legal parenthood, and how that proxy functions in new statutory frameworks designed to recognize more than two legal parents for a child. Holding out was originally conceived as a mechanism to allow unmarried biological fathers to seek legal parent status. Holding out has been extended to intended and intentional parents in surrogacy and assisted reproductive technology as well as to married and unmarried same sex partners. In these iterations, holding out has facilitated legal parent recognition as the modern family form has evolved to include more …


Contribution Of Phosphorylation To Hp1a Function, James Walts Jun 2026

Contribution Of Phosphorylation To Hp1a Function, James Walts

ETDs from 2020-2029

Heterochromatin Protein 1 (HP1) family members are highly conserved, non-histone chromosomal proteins essential for heterochromatin formation and transcriptional regulation. In Drosophila melanogaster, HP1a functions both as a transcriptional repressor and activator, as well as other functions, and undergoes post-translational modifications, including phosphorylation. The functional consequences of HP1a phosphorylation remain largely unexplored. This thesis investigates the role of phosphorylation at serines 89/90/91 (S899091) of HP1a by generating two mutant alleles: a phospho-mimic (SE) and a phospho-block (SA). Both alleles produce stable mRNA transcripts; however, Western blot analysis revealed reduced protein accumulation relative to wildtype HP1a. Homozygous phospho-block animals are embryonic lethal …

Shaping Fibroblast Fate To Drive Fibrotic Remodeling In Pulmonary Fibrosis: Decoding S100a4, Spring Li

ETDs from 2020-2029

Idiopathic pulmonary fibrosis (IPF) is a progressive interstitial lung disease characterized by persistent fibroblast activation, excessive extracellular matrix (ECM) deposition, and irreversible remodeling of lung architecture. A central feature of disease progression is the accumulation of fibroblasts that evade apoptosis and persist in a pathologically activated state. However, the molecular mechanisms that sustain this aberrant phenotype remain incompletely understood. The calcium-binding protein S100A4 has been implicated in fibrotic processes, but its role in orchestrating fibroblast fate and profibrotic behavior has not been fully defined, particularly with respect to its influence on fibroblast survival and activation in IPF. In the first …

ETDs from 2020-2029

Accurate clinical risk prediction plays an important role in improving patient outcomes, particularly in perioperative settings where early intervention can influence care decisions. Although machine learning has shown promising results using electronic health record (EHR) data, its use in clinical practice is often limited by complex development processes, the need for hyperparameter tuning, and variability in performance across datasets. These challenges are especially relevant in data-scarce clinical settings. This thesis evaluates TabPFN-2.5, a transformer-based tabular foundation model designed to perform classification without dataset-specific training. The model was applied to two real-world perioperative prediction tasks: unplanned care escalation (UCE) following post-anesthesia …
