The Role Of Leptin In The Regulation Of The Soluble Amyloid Precursor Protein Alpha (Sappa) Levels In Non-Small Cell Lunch Cancer (Nsclc) Cell Media, Benjamin Haddad

Senior Honors Theses and Projects

We previously found that the levels of soluble amyloid precursor protein α (sAPPα) are partly regulated by acetylcholinesterase (AChE) in human non-small cell lung cancer cell lines A549 (p53 wild-type) and H1299 (p53-null). In this study, we hypothesize that sAPPα is partly regulated by leptin, a hormone classically recognized for its anorexigenic role in appetite regulation— yet recently shown to play a role in cancer cell signaling. It was observed that cells treated with leptin exhibited greater concentrations of sAPPα and lower concentrations of Aβ40/42 in the media compared to those of cells left untreated. An opposite effect was observed …

Breaking The Bind: Rethinking Non-Compete Agreements In A Federal Framework, Stephen Hendricks

Chapman Law Review

In April 2024, the Federal Trade Commission (FTC) adopted a sweeping rule that bans most non-compete agreements nationwide. Though well-intentioned, the FTC’s categorical prohibition neglects the complex interplay between worker mobility, employer investment, and the protection of legitimate business interests. This Article contends that the United States must move beyond the current false binary of complete prohibition or unregulated enforcement. Drawing on comparative legal analysis, it proposes a federal framework modeled on Germany’s Karenzentschädigung system, under which employers must provide post-employment compensation—typically fifty percent of prior salary—to enforce non-competes.

After tracing the evolution of non-compete doctrine in American law, this …

Social Media, Populism, And Militant Democracy: An Argument For A Change In First Amendment Doctrine, Arvid Kerschnitzki

Chapman Law Review

The First Amendment is often hailed as the cornerstone of American self-government, but the digital age has transformed the public discourse it was meant to protect. Social media platforms, once envisioned as a modern marketplace of ideas, now amplify misinformation, entrench echo chambers, and enable mass manipulation, threatening the democratic ideal of an informed citizenry.

While the current First Amendment doctrine rightly emphasizes the importance of public discourse, that discourse must be inclusive, rational, and reliable to serve its democratic function. Drawing on the concept of militant democracy, this Article argues that contemporary doctrine has lost sight of free speech’s …

Technological Change And The Evolution Of Patent Rights, Paul Rogerson

Chapman Law Review

The history of patent law is characterized by a striking pattern: dramatic, recurring cycles between eras of stronger and weaker patent rights. One theory is that patent law has been adapting to waves of technological change. In periods of rapid technological progress, following major breakthroughs (like the steam engine or the microprocessor), freely granting patents tends to create thickets of overlapping claims that block innovation, and courts have reacted by weakening rights (raising the standard to obtain and enforce a patent).

Existing histories, relying on qualitative methods, have argued that this theory explains certain nineteenth-century legal developments, but have questioned …

Avoiding The Siren Call Of The Clock In “Unreasonable Delay” Data Breach Notification Cases, Evan Yahng

Chapman Law Review

As online personally identifiable information, data breaches, blockchain, Artificial Intelligence, and other trends in the cyber ecosystem proliferate, courts must confront legal questions about data privacy that past courts have kicked down the road.
