Fluorescence labeling and computational analysis of the strut of myosin's 50 kDa cleft.

Fluorescence labeling and computational analysis of the strut of myosin's 50 kDa cleft.

Date: August 2007
Creator: Gawalapu, Ravi Kumar
Description: In order to understand the structural changes in myosin S1, fluorescence polarization and computational dynamics simulations were used. Dynamics simulations on the S1 motor domain indicated that significant flexibility was present throughout the molecular model. The constrained opening versus closing of the 50 kDa cleft appeared to induce opposite directions of movement in the lever arm. A sequence called the "strut" which traverses the 50 kDa cleft and may play an important role in positioning the actomyosin binding interface during actin binding is thought to be intimately linked to distant structural changes in the myosin's nucleotide cleft and neck regions. To study the dynamics of the strut region, a method of fluorescent labeling of the strut was discovered using the dye CY3. CY3 served as a hydrophobic tag for purification by hydrophobic interaction chromatography which enabled the separation of labeled and unlabeled species of S1 including a fraction labeled specifically at the strut sequence. The high specificity of labeling was verified by proteolytic digestions, gel electrophoresis, and mass spectroscopy. Analysis of the labeled S1 by collisional quenching, fluorescence polarization, and actin-activated ATPase activity were consistent with predictions from structural models of the probe's location. Although the fluorescent intensity of the ...

Fluorination Effect on the Conformational Properties of Alkanes

Fluorination Effect on the Conformational Properties of Alkanes

Date: May 2002
Creator: Xu, Wenjian
Description: A Series of fluorophores of the general formular P(CF2)nP and P(CF2)n-1CF3 has been synthesized. Copper catalyzed coupling of 1-bromopyrene and the corresponding mono and di-iodoperfluoroalkanes were used in most cases. For the n=3 dimer, a novel 1,w-perfluoroalkylation of pyrene via bis-decarboxylation of hexafluorogultaric acid was utilized. These compounds, along with suitable hydrocarbon analogs, are being used to study the flexibility of fluorocarbon chains using emission. We have found that the excimer formation for the fluorinated pyrene monomers is highly dependent on concentration and is less efficient than for pyene. Excimer formation for the fluorinated pyrene dimers is much more efficient than for the fluorocarbon monomers and is only slightly concentraion dependent. Steady-state emission spectra indicate hydrocarbon dimers-models form excimers more efficiently than the fluorinated dimers suggesting the fluorinated chains are stiffer than the hydrocarbons. We conducted the temperature-dependent studies and quantified the conformational difference.

Fluorine Adsorption and Diffusion in Polycrystalline Silica

Fluorine Adsorption and Diffusion in Polycrystalline Silica

Date: December 1998
Creator: Jin, Jian-Yue
Description: The measurement of fluorine penetration into archeological flint artifacts using Nuclear Reaction Analysis (NRA) has been reported to be a potential dating method. However, the mechanism of how fluorine is incorporated into the flint surface, and finally transported into the bulk is not well understood. This research focuses on the study of the fluorine uptake phenomenon of flint mineral in aqueous fluoride solutions. Both theoretical and experimental approaches have been carried out. In a theoretical approach, a pipe-diffusion model was used to simulate the complicated fluorine transportation problem in flint, in which several diffusion mechanisms may be involved.

The Flute: the Mechanical Improvements on the Body of the Orchestral Instrument since 1847

Date: August 1994
Creator: Nussbaum, Carolyn
Description: This thesis uniquely explains the mechanical improvements which have occurred to the flute over the last 147 years. Theobald Boehm revolutionized the flute by changing many of its components culminating with the 1847 model flute. Since that time other improvements have been made which enhance the flute's capabilities in terms of pitch, tone, timbre, and simplification offingeringpassages. Among those improvements which are discussed in the following pages are the Dorus G-sharp key, the gizmo key, the Cooper scale, and The Brogger Mekanik as well as the makers behind the various improvements including Vincent Dorus, George Barrere, and Albert Cooper.

A follow-up study of a masters program for teachers of students with emotional/behavioral disorders.

Date: August 2008
Creator: Walter, Paulette C.
Description: Educators today are faced with a worthy goal. Every student, including those with emotional and behavioral disorders (EBD), must be taught by a qualified teacher. However, recruiting, training, and retaining quality special education teachers continue to confound the field. The purpose of this study was to determine if the completion of a NCATE/CEC (National Council for Accreditation of Teacher Education/Council for Exceptional Children) approved masters program specializing in EBD from a well-known university increased the confidence in knowledge and skills of special educators, the numbers of special educators, and/or the retention of special educators working with students with EBD. The sample in this study was composed of 199 students who had completed the master's degree in special education who specialized in emotional/behavioral disorders from 1985 to 2005. Data were compiled from 80 students at a response rate of approximately 40%. Additionally, five respondents participated in face-to-face interviews. The data did not lend themselves to the quantitative analysis and thus pose a limitation to the generalizability of this study. However, combined with the qualitative analysis, the study provided a rich analysis of a program whose graduates stay in the field of special education providing services to students with EBD.

A Follow-Up Study of Autistic and Autistic-Like Children

A Follow-Up Study of Autistic and Autistic-Like Children

Date: August 1988
Creator: McCallon, Denise
Description: Autism is a lifelong handicapping disorder that occurs on a continuum of severity. Children who show mild autistic behaviors but do not meet the criteria for a diagnosis of autism are often called autistic-like, but it is not known if their development and functioning are similar to that of autistic children. A follow-up study was done on 35 autistic and autistic-like children who were an average of 3 years of age when initially seen. Initial test scores indicated that the children were similar on measures of intellectual/developmental functioning, receptive vocabulary, and adaptive functioning. Approximately 4 years later they were evaluated again. Using the Childhood Autism Rating Scale, the children were divided at follow-up into three groups: nonautistic, mildly/moderately autistic, and severely autistic. Most children made gains on intelligence tests and displayed a diminishing number of autistic symptoms. Changes in nonverbal intelligence, adaptive functioning and receptive vocabulary scores depended on group membership. The results are discussed in relation to the reported stability of cognitive functioning in young autistic children and the implications for clinical practice, early intervention, and research on attachment. The nature of the syndrome of autism is also discussed, particularly in its relation to the milder, atypical children. The ...
