The effect of 2-aminoethyl-2-thiopseudourea[superscript .]Br[superscript .]HBr (AET),
2-mercaptoethylamine[superscript .]HC1 (MEA) and trisodium calcium chelate of
diethylenetriaminepentaacetic acid (CaNa₃DTPA) on the radiosensitivity
of rat fetus was investigated. A total of 1256 fetuses were
critically examined.
Exposure of rats to 200 r whole-body X-irradiation at 9.5 days
of gestation resulted in a...
Health officials have recently been sounding the alarm that depression will soon
surpass many of the major medical conditions in causing disability among adults. Recent
demographic and health trends are generating public health concern about depression.
First, the prevalence of chronic conditions has dramatically increased over the last several
generations....
Wet meadow ecosystems are a useful natural laboratory in which to explore feedbacks between biogenic and geologic controls on valley bottom landforms. Characterized by flat valley floors flanked by higher-gradient hillslopes, these meadows are singular both in that they represent depositional features in what is primarily an erosional environment, and...
Co-teaching and collaboration are an increasingly popular service model for English as a second language (ESL). In this model, the language specialist, sometimes called the ESL teacher, works together with a content teacher, each using their respective expertise to meet the needs of students who are identified as English learners...
Neisseria gonorrhoeae is the sexually transmitted pathogen responsible for millions of cases of gonorrhea worldwide each year. Rapidly-spreading antibiotic resistance is diminishing the ability to effectively treat a disease with significant consequences to female and male reproductive health, as well as to neonatal well-being. A protective vaccine has the potential...
Most energy policies that are implemented in the United States dictate how energy is produced, distributed, and consumed, but policies generally neglect to fully investigate how these decisions impact population health. Individuals who live near energy sector components are often different to those that reside further away and change over...
Targeting the epigenome, including the use of histone deacetylase (HDAC) inhibitors, is a novel strategy for cancer chemoprevention. Sulforaphane (SFN), a compound found at high levels in broccoli and broccoli sprouts, is a potent inducer of Phase 2 detoxification enzymes and inhibits tumorigenesis in animal models. SFN also has a...
The topics in this dissertation center on the snow processes that dominate mountain environments in the Western U.S. and Alaska, particularly in locations lacking long-term observational datasets or locales that are difficult to access in-person. Some are currently glacierized or have been glaciated in the recent past. Each of the...
Families and early care and education (ECE) programs are two important contexts in which young children develop (Bronfenbrenner & Morris, 2006). Nearly half of all preschoolers are cared for in nonrelative care (e.g. child care center, preschool, Head Start, teacher’s home; Laughlin, 2013), and ECE programs have the potential to...
