Abstract Organisms employ inducible defenses to prevent predation. This occurs when the organism recognizes an environmental cue that leads to the expression of the defensive trait. In marine systems this cue is often chemical in nature. Several...
The mouse frizzy (fr) mutation is a Mendelian recessive trait that affects hair structure and formation in mice. The mutation arose in a mouse of mixed origin at the Jackson Lab (Bar Harbor, ME) in 1951. Frizzy is known to be linked to other genes...
Depression is characterized by a mood and behavior, that can affect the ability of
a person to perform daily activities and interact with others. Depression is an illness that
can be caused by biochemical and environmental changes. Chemical...
Fluorescence in situ hybridization; Lungs -- Cancer
This study examines the relationship ovserved between the chromosomal
abnormalities detected by FISH and available clinical data on cancer type on
forty lung cancer specimens. An attempt to derive correlation between subtype
of lung cancer and type...
The pairing and recombination of homologous regions of the X and Y chromosomes, in an area known as the pseudoautosomal region (PAR), has been a phenomenon of interest since its discovery in 1934. Its presence seems to be limited to eutherian...
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...
Ahearn et al. (J. Heredity 93:210-213) have previously shown that the rat fuzzy and Charles River "hairless" mutations are defects in the same gene on rat Chromosome 1, and are likely orthologues of mouse frizzy (abbreviated fr) on mouse Chromosome...
The recessive male sterility and histoincompatibility mutation (mshi) in the mouse generates pleiotropic effects on graft transplantation and male reproduction. Previous analysis of backcross mice using a large set of microsatellite markers has...
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...
Parental behavior in animals; Rats -- Physiology; Animal mutation
Rats that are hypotrichotic (lacking normal hair) due to the autosomal recessive
shorn (shn) mutation showed a low survival rate in brother by sister matings in a breeding
colony of SU/Csu rats. The majority of rats died before weaning. Subsequent...
This thesis explores the concept of human happiness, focusing primarily on
adolescents and their experience of this distinct state of being. An historical approach is
taken, reviewing how happiness has been defined and treated throughout the years...
Infertility is a common problem, affecting approximately 10% of all couples attempting to conceive (Watson et al., 1998). Although numerous potential causes of human infertility exist, many cases are thought to have genetic etiologies, including...
United States -- Emigration and immigration -- Government policy; United States -- Emigration and immigration -- 20th century
The original purpose of this thesis was to examine the forces behind the anti-immigrant movement in United States history culminating in the Quota Law of 1924. However, after much analysis that thesis was expanded to examine the changing nature of...
