Transforming growth factor-alpha (TGFa), a member of the endothelial growth
factor (EGF) family of mitogens, was previously thought to exist solely in neoplastic
cells and the quickly dividing cells of a developing fetus. Since then, TGFa...
Myrmecochory is a widespread and diverse mutualism between ants and flowering plants in which a modified seed appendage, an elaiosome, is provided to ants as a food reward. In eastern North American forests, ants of the genus Aphaenogaster disperse...
Evolution-education in America has been a fascination of the public ever since the Scopes trial of the 1920's. The controversy has not subsided despite the supreme court's rulings regarding this topic. As has been the case with many controversial...
Studying an ecological system is a complex and difficult process. Studying a fossil ecology is even more difficult. There are few fossil deposits containing not only most of the organisms originally present, but also preserved well enough to make...
Exercise-induced asthma, more accurately called exercise induced bronchoconstriction (EIB) has been defined as a clinical syndrome characterized by transient airflow obstruction following several minutes of exercise. EIB is also recognized as...
Crabs -- Long Island Sound (N.Y. and Conn.); Introduced animals -- Long Island Sound (N.Y. and Conn.)
Hemigrapsus sanguineus, the Japanese shore crab, is native to the western Pacific
Ocean and was first reported in Long Island Sound in 1992. Since then, it has become
firmly established and, in many locations, is the most common crab in the rocky...
The traprock ridge environments of Connecticut and Massachusetts are unique and little studied. This project examined the combination of tree and shrub species, their abundance, their dispersion pattern, and the pattern of succession on the Onion...
The male sterility and histoincompatibility mutation (mshi) is an autosomal recessive mutation that produces apparently pleiotropic effects in mice. Mice homozygous for mshi manifest two distinct phenotypes. In both male and female mice, the...
Single-sex schools; Single-sex schools -- Connecticut -- Avon; Avon Old Farms School (Avon, Conn.) -- History
Over the last several decades statistics reveal that there is worldwide underachievement of boys in school. Regardless of race, ethnicity, culture, or economic background, boys as a group are struggling to be effectively educated. While girls are...
The prophage of bacteriophage P1 is a unit copy plasmid, stable in Escherichia coli during cell division due to its partition system. The active P1 partition system consists of two genes, parA and parB, and a cis-site, parS. ParS contains all of...
Human reproductive technology; Fertilization in vitro, Human
The purpose of this study was to evaluate the outcome of Intracytoplasmic Sperm Injection (ICSI) in patients with previous unexplained fertilization failure (≤20%) after conventional in vitro fertilization (IVF) in our program and to compare them...
The autosomal recessive mshi mutation in BALB/cBy mice phenotypically causes reduced testis size and male sterility in homozygotes. The development of the mshi male generative organs, prior to three weeks of age, appears to lack observable...
During the last decade, new technologies created a deluge of potential drug targets. Sifting through thousands of potential drug targets is a major industry bottleneck. Pharmaceutical companies can save billions of dollars by identifying most...
Phylogeography using nested clade analysis (NCA) is able to apply biological inferences to the history of populations of organisms independent of the population's structure. In the Western United States, phrynosomatine lizards have a complex...
Rats lacking normal hairy coats were discovered several years ago among our colony of hairy albino rats. The trait was found to be controlled by a recessive allele of a gene we designated shorn (shn), which mapped to distal end of rat chromosome 7....
Physical fitness for men -- Measurement; Energy metabolism -- Measurement; Vitamin D
Physical performance is related to functional disabilities. Better interventions to improve function may be targeted if the determinants of physical performance are understood. We evaluated predictors of performance. The relationship of physical...

The origins of psychology looked at studying the "psyche" or soul of an individual, as well as the interactions between the biological organism and its physical and social environment. Throughout the evolution of psychology, scientific study and...
Minor histocompatibility (H) antigens are typically identified as barriers to transplantation in graft exchange experiments between major histocompatibility complex (MHC)-matched hosts (Bailey 1975; Snell and Bunker 1960). This approach has allowed...
Balanidae -- California -- San Diego; Seashore biology -- California -- San Diego; La Jolla (San Diego, Calif.)
Growth rates, mortality, and the total number of eggs of the intertidal acorn barnacle, Chthamalus fissus, were studied at La Jolla, California. Both mm and % (absolute and relative) growth rates compared to different body sizes were calculated...
This thesis focuses on the alga Polysiphonia subtilissima, specifically its reproductive phenology and photosynthetic rates. At its northern limits including New England, P. subtilissima occurs in areas of lower salinity and in Connecticut it is...
