Title of Document: EFFECTS OF TEMPERATURE ON GENE EXPRESSION AND SEX DETERMINATION IN THE MANGROVE RIVULUS, KRYPTOLEBIAS MARMORATUS Jennifer Strykowski, Master of Science 2011 Directed by: Assistant Professor Dr. Edward F. Orlando, Department of Animal and Avian Sciences Rivulus is a hermaphroditic, self-fertilizing fish species that possesses an ovotestis and, in the wild, exist as androdioeci...

We isolated the complete Foxl2 (Foxl2a) cDNA from the Monopterus albus ovary. An alignment of known Foxl2 amino-acid sequences confirmed the conservation of the Foxl2 open reading frame, especially the forkhead domain and C-terminal region. The expression of Foxl2 was detected in the brain, eyes, and gonads. A high level of Foxl2 expression in the ovary before sex reversal, but its transcripts ...

The binding kinetics of the TCR for its interacting ligand and the nature of the resulting signal transduction event determine the fate of a developing thymocyte. The intracellular tyrosine phosphatase SHP-1 is a potential regulator of the TCR signal transduction cascade and may affect thymocyte development. To assess the role of SHP-1 in thymocyte development, we generated T cell-transgenic mi...

This dissertation project examined the influence of language typology on the use of segmentation cues by second language (L2) learners of English. Previous research has shown that native English speakers rely more on sentence context and lexical knowledge than segmental (i.e. phonotactics or acoustic-phonetics) or prosodic cues (e.g., word stresss) in native language (L1) segmentation. However,...

The field of second language (L2) assessment has continued to evolve since the 1960s, broadening scope inquiry and adopting more sophisticated research methods (Chen, 2011; Kunnan, 2014). Technological innovations have allowed wider application tools for design, development, analysis (Purpura & Banerjee, 2021). In addition quantitative methods, qualitative also been widely adopted, providin...

We investigated whether the L2/HNK-1 carbohydrate epitope, expressed by two unusual glycolipids and several neural adhesion molecules, including L1, neural cell adhesion molecule, J1, and the myelin-associated glycoprotein, is involved in adhesion. Monoclonal L2 antibodies, the L2/HNK-1-reactive, sulfate-3-glucuronyl residue carrying glycolipids (L2 glycolipid) and a tetrasaccharide derived fro...

Most studies on bilingual language development focus on children's second language (L2). Here, we investigated first language (L1) development of Polish-English early migrant bilinguals in four domains: vocabulary, grammar, phonological processing, and discourse. We first compared Polish language skills between bilinguals and their Polish non-migrant monolingual peers, and then investigated the...

introduction: cervical cancer is the second most common cancer in women worldwide and the role of human papillomavirus (hpv) has been proved in its etiology. the currentley available l1-capsid-protein-based vaccine is highly immunogenic and very high titers of serum antibodies can be obtained by its injection, but unfortunately it is restricted to only a few hpv genotypes and is relatively expe...

This is a longitudinal case study of two Farsi-speaking children learning English: ‘Bernard’ and ‘Melissa’, who were 7;4 and 8;4 at the start of data collection. The research deals with the initial state and further development in the child second language (L2) acquisition of syntax regarding the presence or absence of copula as a functional category, as well as the role and degree of L1 influe...
