Assisted Reproduction Techniques In Horses: The Challenge, Theerawat Tharasanit, Mongkol Techakumphu Sep 2007

Assisted Reproduction Techniques In Horses: The Challenge, Theerawat Tharasanit, Mongkol Techakumphu

The Thai Journal of Veterinary Medicine

Assisted reproduction techniques (ARTs), such as artificial insemination and embryo transfer are well established and have been used in a wide range of species. To date, the economic impact of these ARTs in horses has rapidly increased. While many studies have attempted to improve the efficiency of ARTs, overall success remains relatively restricted due principally to a limited knowledge of the unique reproductive physiology of this species. Improving efficiency of particular techniques has become an affordable milestone in the development of ARTs in equine reproduction.

School of Dentistry Faculty Research and Publications

Root fractures involve damage to pulp, cementum, dentin, and periodontal ligaments. These injuries affect 0.5% to 7% of permanent teeth. Cervical root fractures are less frequently seen and have a worse prognosis compared with the fractures in the apical or middle third of the root. This case report describes the treatment of a cervical root fracture in a maxillary central incisor. After removal of the coronal fragment, the root was filled temporarily with calcium hydroxide and orthodontic extrusion was initiated. The remaining root portion was elevated above the epithelial attachment and a successful coronal restoration was made using the natural …

14-3-3 Proteins Interact With The Beta-Thymosin Repeat Protein Csp24, Terry Crow, Juan-Juan Xue-Bian, Joseph T Neary Aug 2007

14-3-3 Proteins Interact With The Beta-Thymosin Repeat Protein Csp24, Terry Crow, Juan-Juan Xue-Bian, Joseph T Neary

Faculty, Staff and Student Publications

Conditioned stimulus pathway protein 24 (Csp24) is a beta-thymosin-like protein that is homologous to other members of the family of beta-thymosin repeat proteins that contain multiple actin binding domains. Actin co-precipitates with Csp24 and co-localizes with it in the cytosol of type-B photoreceptor cell bodies. Several signal transduction pathways have been shown to regulate the phosphorylation of Csp24 and contribute to cellular plasticity. Here, we report the identification of the adapter protein 14-3-3 in lysates of the Hermissenda circumesophageal nervous system and its interaction with Csp24. Immunoprecipitation experiments using an antibody that is broadly reactive with several isoforms of the …

Engaging Primary Health Care Providers In The Promotion Of Healthy Weight Among Young Children: Barriers And Enablers For Policy And Management, Lydia A. Hearn, Margaret R. Miller, Donna S. Cross

Research outputs pre 2011

Recent national efforts to stem the alarming growth of childhood overweight and obesity in Australia have highlighted the importance of preventative strategies that focus beyond the child-on parents, families, primary health care providers (PHCPs) and child care services. But, while such efforts have to date focused on school-based interventions, once poor eating habits and sedentary lifestyles have set in, a growing body of research is indicating that PHCPs can play a more influential role in monitoring and modifying factors affecting prevention and early intervention in preschool children. This paper presents the findings of a systematic review to: (a) identify key …

Medicare's Use Of Risk Adjustment, Gerald F. Kominski Aug 2007

Medicare's Use Of Risk Adjustment, Gerald F. Kominski

National Health Policy Forum

Medicare accounts for expected differences in resource needs of patients or health plan enrollees by risk-adjusting the payments it makes to health care facilities, such as hospitals, skilled nursing facilities, and home health agencies, and the premiums it pays to health plans. Risk adjustment is intended to ensure that payments or premiums are adequate for patients or plan enrollees who require more resources than average in order to protect beneficiary access as well as the financial condition of the provider or plan. At the same time, risk adjustment lowers payments or premiums for beneficiaries who are expected to use fewer …

Phosphorylation-Induced Conformational Switching Of Cpi-17 Produces A Potent Myosin Phosphatase Inhibitor, Masumi Eto, Toshio Kitazawa, Fumiko Matsuzawa, Sei-Ichi Aikawa, Jason A. Kirkbride, Noriyoshi Isozumi, Yumi Nishimura, David L. Brautigan, Shin-Ya Ohki

Department of Molecular Physiology and Biophysics Faculty Papers

Phosphorylation of endogenous inhibitor proteins specific for type-1 Ser/Thr phosphatase (PP1) provides a mechanism for reciprocal coordination of kinase and phosphatase activities. Phosphorylation of Thr38 in the inhibitor protein CPI-17 transduces G-protein-mediated signaling into a > 1000-fold increase of inhibitory potency toward myosin phosphatase. We show here the solution NMR structure of phospho-T38-CPI-17 with r. m. s. d. of 0.36 ± 0.06 Å for the backbone secondary structure, which reveals how phosphorylation triggers a conformational change and exposes the PP1 inhibitory surface. This active conformation is stabilized by the formation of a hydrophobic core of intercalated side-chains, which is not formed …

Characterization Of A 30s Ribsomal Subunit Intermediate Found In Escherichia Coli Cells Growing With Neomycin And Paromomycin., Cerrone Renee Foster

Electronic Theses and Dissertations

The bacterial ribosome is a target for inhibition by numerous antibiotics. Neomycin and paromomycin are aminoglycoside antibiotics that specifically stimulate the misreading of mRNA by binding to the decoding site of 16S rRNA in the 30S ribosomal subunit. Recent work has shown that both antibiotics also inhibit 30S subunit assembly in Escherichia coli and Staphylococcus aureus cells. This work describes the characteristics of an assembly intermediate produced in E.coli cells grown with neomycin or paromomycin. Antibiotic treatment stimulated the accumulation of a 30S assembly precursor with a sedimentation coefficient of 21S. The particle was able to bind radio labeled antibiotics …
