Lumbriculus variegatus has great ability to regenerate from small fragments into a new worm. In this study, we expose the worms to the voltage-gated sodium channel blocker Tricaine (MS-222) and examine somatic regeneration of heads and tails following body transection. Images of regenerating worms under normal conditions and treated worms with (1700μm) of tricaine were examined after amputation through TEM, SEM, and light level. Regeneration of both new head and tail body segments was reduced in the presence of tricaine, especially in the tail regeneration. Therefore, voltage- gated sodium channels showed to affect regeneration in the blackworms.

In the 1960’s, the Indian Health Service (IHS) introduced and provided native american women different methods of birth control. The US government agency personnel, including the IHS, targeted native americans due to their high birth rate. As opposed to popular belief, native women were often subsidized and used as test subjects with the goal of population control under the American Department of Health, Education, and Welfare (HEW.) This lead to an abundance of native women becoming sterilized by their physician without their consent.

I decided to do scientific studies on the stream flow rate as well as water depth, width, and terrace height on two separate creeks in Humboldt county. The first creek is called the Jolly Giant creek which is located directly behind founders hall on campus, and the second creek that I decided to do my research on is the Strawberry creek, which is located directly behind my house. I used a measuring road, and measuring tape for my measurements, as well as three distinct objects to float down the creek which was a lemon, a kiwi, and a lacrosse ball.

Minimal research combines the dimensions of political morale to develop a scale that broadly measures political demoralization. Political demoralization can be described as experienced discontentment and distress within the current political system, wherein some people may feel powerless to enact change. (Clark & Kissane, 2002). The current study is the development of a scale of political demoralization, which tests its relationship between political hopelessness, political efficacy and social desirability. Analyses of the PDS demonstrate the scale's reliability and validity.

ANTH 352: Experimental Archaeology is an introduction to the principles and applications used in recreating the technologies of the past. Students participate in research, experimentation and experiential components throughout the term. During the course of the Spring 2018 class, students designed and implemented experimental archaeology projects that included wattle and daub construction, ceramic production and materials, consumables including food, bread and mead, ethnographic and archaeological instrument construction, ship-building, book binding, textile production, and ancient weapon technologies.

HYPOTHETICAL: Sex hormones estrogen and progesterone have been hypothesized to impact FFA release. While these two hormones fluctuate throughout the menstrual cycle, basal rates of FFA release are similar between menstrual cycle phases. Specifically, when looking at the early follicular (EF) and mid luteal (ML) phases, there is differences in plasma or intramuscular FFA release. However, the phase in which estrogen is at its highest and progesterone is at its lowest (late follicular [LF]) has been minimally studied. Additionally, the dynamics of FFA release might vary in non-resting conditions. The purpose of this study was to investigate differences in FFA release between the three phases

There has been an increasing number of Black students entering into higher education, but they continue to have greater disparities in academic achievement when compared to White students. An institution's campus climate has been found to influence student success. This study seeks to examine the factor of campus climate, specifically negative campus racial climate (NCRC), as it relates to the GPA and university satisfaction of Black students at a rural institution. The study adds to the literature by exploring the degree to which involvement (Student-Faculty Involvement (SFI) and Club/Organization involvement (COI)) may act as a moderating force within the relationship.

Humboldt State University Library houses a collection of posters and documents preserving anti-war ephemera and primary sources from the HSU Strike for Peace protest, which took place May 11-15, 1970. This student-organized protest was one of the largest demonstration in Humboldt County’s history to date; it drew support from almost 3,000 students, faculty, and Humboldt community members. The protest stemmed from President Richard Nixon's support of expanding the war into Cambodia, after he had promised the general public to begin the withdrawal of troops from Vietnam.

Understanding the origins of hematopoietic stem cells has been a challenge due to the lack of a marker specific to this cell type. Recently, our lab has functionally proven that HoxB5 is a unique marker for long-term HSCs in adult murine models. Whether HoxB5 is also a marker for HSCs in development, has not been studied. Here, we are labeling HoxB5+ cells found in the yolk sac blood islands at E7.5 by using a genetic tool we generated. We will then analyze all marked cells at several time points during development and adulthood. This project will discover if HoxB5+ cells from the yolk sac contribute to the adult hematopoietic system and the LT-HSC pool.

Identifying sport-related concussions occurs on the sidelines with tests utilized by athletic trainers and other field-side professionals. The Tandem Gait (TG) is a commonly used side line dynamic balance test that has only moderate sensitivity when used alone. Research has demonstrated that incorporating a secondary simultaneous task (i.e. dual-task) to amplify differences in TG performance following injury may amplify the difference due to a concussion. However, a dual-task TG has yet to be established as a clinical assessment of concussion. The aim of this study is to determine the effect of secondary cognitive tasks on performance of the TG in concussed and non-concussed individuals.
