Transcriptional regulation of thyroid development possible interplay of endoderm- and mesoderm-derived morphogenetic signals
… was largely down-regulated in mature adult C-cells. In addition, Isl1 transcript was detected in human medullary thyroid cancer. In paper III, the forkhead transcription factor Foxa2 was found to be an embryonic marker of pharyngeal endoderm, lateral thyroid anlagen (ultimobranchial bodies) …

Motility and Chemotaxis of Erwinia Herbicola and Its Effect on Erwinia Amylovora (Biological Control, Phytobacteriology, Fire Blight)
… by the capillary assay. Actively motile cells were selected from the periphery of swarming colonies grown on soft agar (0.25%) modified Emerson's medium plates minus the ingredient nutrient broth. The optimum growth temperature for producing motile cells was 29 C. Cells were still motile …

Cell loss estimation in an ATM multiplexer loaded with heterogeneous on-off sources
… ATM Multiplexer with a finite buffer of size K (cells) and a single link with capacity C (cells/second). Unlike previous work, we approximate the heterogeneous arrival process using a Markov Modulated Deterministic Process (MMDP). We model the ATM multiplexer as MMDP/D/1/K queueing system, then …

Evaluation of radiolabelled hynic-salmon calcitonin analogues as imaging agents for multiple myeloma and characterisation of novel hynic derivatives as chelators for technetium
Calcitonin is a peptide hormone produced by the C-cells of the thyroids. Calcitonin receptors (CTR) are expressed by osteoclasts in the normal bone and in many cancers such as multiple myeloma (MM), breast and prostate cancer. In this thesis we report on the synthesis and evaluation of Tc-99m …

Relationship of Wound Healing and Angiogenesis to the Cell Kinetics of the Initial Osteogenic Response in Orthopedically Expanded Anterior Maxillary Suture in the Rat
… 1 hour before euthanasia to label DNA of S-phase cells. The premaxilla was dissected free and demineralized. Sections (4 μm thick) were stained with hematoxylin and eosin. Angiogenesis and cell migration were analyzed using a previously established cell kinetics model. The cells were divided into …

Tyrosyl Protein Phosphorylation in Human Bone Cells : Its Potential Role in Mediating Fluoride Induced Osteoblast Proliferation
… field exposure 220 and 96kD), and c) Cells which did not respond to fluoride mitogenically were shown to have no significant fluoride-dependent changes in their levels of tyrosyl phosphorylation. With regards to the mechanism by which fluoride increased tyrosyl phosphorylation, the …

Peptides can be utilized as amino acid sources for protein accretion and cell proliferation by cultured animal cells
… mammary epithelial and ovine myogenic satellite cells. Factors in serum that may be involved in regulating peptide utilization was investigated using MAC-T cells. Growth of MAC-T cells was studied in the presence of methionine-containing dipeptides with 6% desalted adult animal serum from …

The Effect of Hypergravity (2g) on Osteoblast Precursor Cells in the Periodontal Ligament of the Rat
… weightlessness on bone and osteoblast precursor cells has previously been studied. A marked decrease in bone formation, an increase in less differentiated committed osteogenic cells (A+A'), and a decrease in preosteoblast cells (C+D) was noted. To date, the effect of hypergravity (2g) on …

Identification and functional characterisation of novel APC/C interacting proteins
… TIF1\(\gamma\) depletion by RNAi arrests cells in a metaphase-like state characterised by elevated levels of APC/C substrates, cyclin A, cyclin B and CDC20. In support of a role for TIF1\(\gamma\) in regulating mitotic progression by directly targeting the APC/C, cells treated with …

Design of fractional-order analog integrated circuits
… properties of biological materials, tissues or cells. Such element, which exhibits fractional-order impedance properties is known as fractance device. However, there are no commercial fractance devices that make use of the advantages of s^α, integer-order approximations have to be used. For this …

Identifying the signalling pathway of a novel Myostatin Splice Variant (MSV)
… C₂C₁₂ myoblasts that stably expressed MSV. C₂C₁₂ cells expressing MSV had an increased proliferative capacity and showed increased mitochondrial activity (EZ4U assay) as compared to controls. These cells showed an increased abundance of the MRFs MyoD, MRF4 and Myogenin and an increased abundance …

Generalized Frequency Plane Model of Integrated Electromagnetic Power Passives
… theory has been proposed. As multiple L-C cells are putting in parallel, magnetic and capacitive coupling between cells cannot be neglected. To determine the capacitance between two adjacent conductors on top of the same dielectric substrate, Schwarz-Christoffel transformation and its …
