Talk Title: Time as the Fourth Dimension of Cancer Complexity
Abstract: Time as the Fourth Dimension of Cancer Complexity Tumor heterogeneity is the result of both genomic instabilities and mircoenvironmental adaptations under both natural evolution of the disease and treatment pressures. Heterogeneity is mostly evaluated at the cellular level considering the individual cell as the biological unit. We have established a framework of single cell analyses that can integrate high content data at the phenotypic and genotypic level. The number of biological units/single cells analyzed provides the measure of resolution of the quantified heterogeneity. The high-content analysis utilizes the high-definition circulating tumor cell (HD-CTC) assay, which provides for an enrichment-free approach to identify and characterize rare cells. We utilized the HD-CTC assay to study protein biomarker expression combined with single-nucleus sequencing for genome-wide analysis of copy number variation (CNV) in fluid and solid biopsies with sequential sampling over the course of disease evolution. Standardized sample preparation methods that enables quantitative comparisons of multiple specimen types both intra- and inter-patient as well as along the timeline of cancer evolution.
Biography: USC was selected to establish a $16 million cancer research center as part of a new strategy against the disease by the U.S. National Institutes of Health and its National Cancer Institute. The new center is one of 12 in the nation to receive the designation. During the five-year initiative, the Physical Sciences-Oncology Centers will take new, nontraditional approaches to cancer research by studying the physical laws and principles of cancer; evolution and the evolutionary theory of cancer; information coding, decoding, transfer and translation in cancer; and ways to de-convolute cancer's complexity. As part of the outreach component of this grant, the Center for Applied Molecular Medicine is hosting a monthly seminar series.

Talk Title: “Demystifying Concentrated Protein Osmotic Pressure. Resulting Novel Applications for Diagnostics and Therapy”
Series: Invited Chair Series
Abstract: High concentrated multicomponent protein solutions or “crowded” solutions are prevalent throughout nature and, subsequently, they make a substantial contribution to natural functions. In cells, multicomponent protein concentration can be as high as 50 â 400 mg/ml. This high protein concentration has been found to contribute to a number of natural phenomena. As well, concentrated multicomponent protein solutions are inevitable in a number of bioseparations processes. As examples, concentrated proteins are prevalent in the final preparations of many pharmaceuticals products and, in membrane separations, concentrated proteins are the dominant factor in permeate flux resistance. In fact the very high concentration of proteins at membrane surfaces has been considered one of the most important areas in separations research.
The most dramatic contribution that concentrated proteins exert on their surroundings, whether in living cells or on membrane surfaces, is the highly non-ideal osmotic pressure. Understanding these phenomena can provide a tremendous appreciation of natural functions and provide direct design improvements in new separations methods. The current virial expansion paradigm, based on McMillan-Mayer theory, assumes that the non-idealities observed in the osmotic pressure data from crowded protein solutions are almost exclusively the result of protein-protein interaction.
However, we have developed a novel approach to understanding the osmotic pressure of highly concentrated protein solutions based on a free-solvent model. Uniquely, the associated parameters of the model are both physically realistic and independently measureable. Consequently, the results of this free-solvent model has a wide range of applications from providing insight to observed phenomena to providing the impetus for medical diagnostic tools for detecting protein mutations. This presentation will discuss the free-solvent model as well as the practical applications of osmotic pressure in bioengineering.

Talk Title: Multiple spatial coordinate systems for new maps between sensory information and motor commands
Abstract: Humans can learn to make accurate movements when the required map between sensory inputs and motor commands changes, such as when using tools that alter limb dynamics or when sensory information is distorted. Moreover, motor learning can also involve a ââ¬Åuse-dependentââ¬Â component that biases subsequent movements towards those repeated during practice, but that does not require the correction of movement errors. A key question regarding the sensorimotor adaptations that underlie this flexibility is the spatial frame of reference in which remapping is encoded. Are new sensorimotor maps defined according to the particular joint angles or torques required for movement, the native coordinate systems of the relevant sensory information (e.g. retinotopic motion direction), or composite extrinsic coordinate systems such as Cartesian space relative to the body? We have addressed this question in a series of visuomotor adaptation studies in which subjects had to move a cursor to visual targets by exerting isometric forces with the finger or wrist. We assessed how adaptation of the initial movement direction generalized to new target directions, postures and between left and right limbs, to systematically manipulate the alignment of the learned perturbation in various spatial coordinate systems. For transfer of visuomotor adaptation between left and right limbs, and generalization of visuomotor gain adaptation, transfer of adaptation only occurred when visuomotor distortion had identical effects in eye- and joint-based coordinates bilaterally. However, generalization of visoumotor adaptation to different postures within a single limb, and bias in force direction generated in response to repetition of a single movement direction were expressed according to a purely extrinsic or visual (rather than limb-based) reference frame. The results imply that new visuomotor maps are encoded in neural circuits associated with both intrinsic and extrinsic movement representations, but that the behavioral outcomes of remapping (i.e. generalization patterns) depend on the sensory context.
Biography: Dr Carroll completed his doctorate in Neuroscience at the University of Queensland in 2001. He was awarded an Isaac Walton Killam Memorial Scholarship to pursue postdoctoral studies at the University of Alberta in 2002, before accepting a position as a Lecturer in Human Motor Control at the University of New South Wales in 2003. He joined the School of Human Movement Studies as a Senior Lecturer in July 2007.
Dr Carrollââ¬â¢s research interests lie in the broad field of integrative human physiology. His work spans the fields of exercise science and integrative neuroscience, with a focus on determining how the central nervous system is reorganised as a consequence of motor learning and exercise. He has a specific interest in the area of strength training. Dr Carrollââ¬â¢s research involves the application of electro-physiological techniques such as Transcranial Magnetic Stimulation (TMS), peripheral nerve stimulation, and electromyography (EMG) in experiments involving human subjects. The ultimate purpose of his work is to generate basic knowledge that will lead to the development of exercise protocols that yield maximal benefits for rehabilitation and injury prevention. His work has been funded by the Australian Research Council (ARC) since 2004

Talk Title: Conversion of sensory signals into perceptual decisions
Abstract: Most perceptual tasks require sequential steps to be carried out. This must be the case, for example, when subjects discriminate the difference in frequency between two mechanical vibrations applied sequentially to their fingertips. This perceptual task can be understood as a chain of neural operations: encoding the two consecutive stimulus frequencies, maintaining the first stimulus in working memory, comparing the second stimulus to the memory trace left by the first stimulus, and communicating the result of the comparison to the motor apparatus. The divisions between these steps may be artificial, but breaking the problem into pieces is helpful. Here I discuss several such pieces, although, in the long run, I aim for an integrated understanding of the perceptual processes, at least to the extent possible within the minimalist environment of a laboratory task.
