Novel Anti-Decay Self-Setting Paste Of Hydroxyapatite/Collagen Nanocomposite Utilizing Gptms, Masanori Kikuchi, Taira Sato, Mamoru Aizawa, Yuki Shirosaki

Composites at Lake Louise (CALL 2015)

Bone is a typical inorganic/ortganic nanocomposite mainly composed of hydroxyapatite (HAp) nanocrystals and collagen molecules. The composition and nanostructure is closely related to bone’s biomechanical and biochemical properties. One of the most important things for bone is a bone remodeling process that maintains mechanical strength of bone to allow walking and running as well as homeostasis of calcium in our body. In fact, sintered HAp composed of HAp crystals approximately 1 µm in particle size is considered as non-bioresorbable; however HAp nanocrystals easily resorbed by osteoclasts. A hydroxyapatite/collagen bone-like nanocomposite (HAp/Col) was successfully synthesized by the authors via self-organizing process. …

Nature’S Tough Composites: A Look Into Biological Fibrous Architectures, Christopher Salinas

Composites at Lake Louise (CALL 2015)

Over a period of hundreds of millions of years, numerous examples of biological organisms have evolved light-weight, strong, and tough composite materials in order to adapt to ecological pressures and thrive in their specific niches. These composite structures consist of fiber-reinforced materials with different architectures including lamellar, cellular and helicoidal motifs. This lamellar motif is a common design utilized by a variety of distantly related organisms from mollusks to plants (e.g., queen conch and bamboo). The strength of the structures are dependent on the orientation of the reinforcing fibers. The fiber-matrix interface increases the toughness of the composite through crack …

Exploration Of The Materials Paradigm With Respect To Bioinspiration, John Nychka

Composites at Lake Louise (CALL 2015)

From the perspective of materials science and engineering the materials paradigm has traditionally been made of four grouped, and interrelated, fundamental aspects of materials: structure, properties, processing/synthesis, and performance. In order to make connections between these aspects we often rely on characterization techniques. When considering the field of bioinspiration, does the materials paradigm adequately cover what nature has to offer? Our way of approaching the issue of bioinspiration has largely been based in applying the materials paradigm, however, is there anything missing in our approach? Can we map nature to the materials paradigm? How can we? What can the paradigms …

Controlling The Interfacial Properties Of One-Dimensional Nanostructures, Kirk Ziegler

Composites at Lake Louise (CALL 2015)

The high surface area of nanomaterials dictates that the interface with their surroundings is important in determining their properties or functionality. For example, all atoms in single-walled carbon nanotubes (SWCNTs) exist on the surface and, therefore, have excellent sensing capabilities. The interface of SWCNTs with their surroundings is also important to their application in polymer composites, devices, drug delivery, bioimaging and biosensing. Understanding and ultimately controlling these surface layers is important because of its influence on dispersion, reactivity, adsorption of pollutants, and interaction with biological materials. SWCNT interfaces are often altered with surfactants to improve their dispersion in aqueous suspensions. …

Multilayer Nanocoatings Capable Of Separating Gases, Killing Bacteria And Stopping Fire, Jaime Grunlan

Composites at Lake Louise (CALL 2015)

Layer-by-layer (LbL) assembly is a conformal coating “platform” technology capable of imparting a multiplicity of functionalities on nearly any type of surface in a relatively environmentally friendly way. At its core, LbL is a solution deposition technique in which layers of cationic and anionic materials (e.g. nanoparticles, polymers and even biological molecules) are built up via electrostatic attractions in an alternating fashion, while controlling process variables such as pH, coating time, and concentration. Here we are producing nanocomposite multilayers (50 – 1000 nm thick), having 10 – 96 wt% clay, that are completely transparent and exhibit oxygen transmission rates below …

Biologically Inspired And Impact-Resistant Composites, David Kisailus

Composites at Lake Louise (CALL 2015)

There is an increasing need for the development of multifunctional lightweight materials with high strength and toughness. Natural systems have evolved efficient strategies, exemplified in the biological tissues of numerous animal and plant species, to synthesize and construct composites from a limited selection of available starting materials that often exhibit exceptional mechanical properties that are similar, and frequently superior to, mechanical properties exhibited by many engineering materials. These biological systems have accomplished this feat by establishing controlled synthesis and hierarchical assembly of nano- to micro-scaled building blocks. This controlled synthesis and assembly require organic that is used to transport mineral …

Adaptive Evolution Of Eel Fluorescent Proteins From Fatty Acid Binding Proteins Produces Bright Fluorescence In The Marine Environment, David F. Gruber, Jean P. Gaffney, Shaadi Mehr, Rob Desalle, John S. Sparks, Jelena Platisa, Vincent A. Pieribone

Publications and Research

We report the identification and characterization of two new members of a family of bilirubin-inducible fluorescent proteins (FPs) from marine chlopsid eels and demonstrate a key region of the sequence that serves as an evolutionary switch from non-fluorescent to fluorescent fatty acid-binding proteins (FABPs). Using transcriptomic analysis of two species of brightly fluorescent Kaupichthys eels (Kaupichthys hyoproroides and Kaupichthys n. sp.), two new FPs were identified, cloned and characterized (Chlopsid FP I and Chlopsid FP II). We then performed phylogenetic analysis on 210 FABPs, spanning 16 vertebrate orders, and including 163 vertebrate taxa. We show that the fluorescent FPs diverged …

Wildlife In U.S. Cities: Managing Unwanted Animals, John Hadidian

Conservation Collection

Conflicts between people and wild animals in cities are undoubtedly as old as urban living itself. In the United States it is only of late, however, that many of the species now found in cities have come to live there. The increasing kind and number of human-wildlife conflicts in urbanizing environments makes it a priority that effective and humane means of conflict resolution be found. The urban public wants conflicts with wildlife resolved humanely, but needs to know what the alternative management approaches are, and what ethical standards should guide their use. This paper examines contemporary urban wildlife control in …

The Transient Receptor Potential Melastatin 2 (Trpm2) Channel Contributes To Beta-Amyloid Oligomer-Related Neurotoxicity And Memory Impairment, Valeriy G. Ostapchenko, Megan Chen, Monica S. Guzman, Yu-Feng Xie, Natalie Lavine, Jue Fan, Flavio H. Beraldo, Amanda C. Martyn, Jillian C. Belrose, Yasuo Mori, John F. Macdonald, Vania F. Prado, Marco A. M. Prado, Michael F. Jackson

Anatomy and Cell Biology Publications

In Alzheimer's disease, accumulation of soluble oligomers of beta-amyloid peptide is known to be highly toxic, causing disturbances in synaptic activity and neuronal death. Multiple studies relate these effects to increased oxidative stress and aberrant activity of calcium-permeable cation channels leading to calcium imbalance. The transient receptor potential melastatin 2 (TRPM2) channel, a Ca2+-permeable nonselective cation channel activated by oxidative stress, has been implicated in neurodegenerative diseases, and more recently in amyloid-induced toxicity. Here we show that the function of TRPM2 is augmented by treatment of cultured neurons with beta-amyloid oligomers. Aged APP/PS1 Alzheimer's mouse model showed increased levels of …

Saccular Transcriptome Profiles Of The Seasonal Breeding Plainfin Midshipman Fish (Porichthys Notatus), A Teleost With Divergent Sexual Phenotypes, Joshua J. Faber-Hammond, Manoj P. Samanta, Elizabeth A. Whitchurch, Dustin Manning, Joseph A. Sisneros, Allison B. Coffin

Biology Faculty Publications and Presentations

Acoustic communication is essential for the reproductive success of the plainfin midshipman fish (Porichthys notatus). During the breeding season, type I males use acoustic cues to advertise nest location to potential mates, creating an audible signal that attracts reproductive females. Type II (sneaker) males also likely use this social acoustic signal to find breeding pairs from which to steal fertilizations. Estrogen-induced changes in the auditory system of breeding females are thought to enhance neural encoding of the advertisement call, and recent anatomical data suggest the saccule (the main auditory end organ) as one possible target for this seasonal modulation. Here …

Ferroelectric Hfo2 For Emerging Ferroelectric Semiconductor Devices, Karine Florent

Theses

The spontaneous polarization in ferroelectrics (FE) makes them particularly attractive for non-volatile memory and logic applications. Non-volatile FRAM memories using perovskite structure materials, such as Lead Zirconate Titanate (PZT) and Strontium Bismuth Tantalate (SBT) have been studied for many years. However, because of their scaling limit and incompatibility with CMOS beyond 130 nm node, floating gate Flash memory technology has been preferred for manufacturing. The recent discovery of ferroelectricity in doped HfO2 in 2011 has opened the door for new ferroelectric based devices compatible with CMOS technology, such as Ferroelectric Field Effect Transistor (FeFET) and Ferroelectric Tunnel Junctions (FTJ).

A Cognitive Neural Architecture Able To Learn And Communicate Through Natural Language, B Golosio, A Cangelosi, O Gamotina, Gl Masala

School of Engineering, Computing and Mathematics

Communicative interactions involve a kind of procedural knowledge that is used by the human brain for processing verbal and nonverbal inputs and for language production. Although considerable work has been done on modeling human language abilities, it has been difficult to bring them together to a comprehensive tabula rasa system compatible with current knowledge of how verbal information is processed in the brain. This work presents a cognitive system, entirely based on a large-scale neural architecture, which was developed to shed light on the procedural knowledge involved in language elaboration. The main component of this system is the central executive, …

P27 Drives Pi3k-Dependent Cancer Metastasis By Activating Emt Transcription Factors To Induce An Emt Program, Alexandra Besser

Open Access Dissertations

In normal cells, p27 regulates cell cycle and functions as an atypical tumor suppressor. Unlike typical tumor suppressors such as p16 and pRb, p27 gene deletions or mutations are rarely observed in human cancers. Instead, p27 is deregulated through either excess degradation or through key C-terminal phosphorylations, in human cancers. Phosphorylation at T157 or T198 by different PI3K effector kinases allows p27 to take on new binding partners and promote oncogenic transformation. This thesis addresses the functional contribution of T157 and T198-phosphorylated, deregulated p27 to cancer progression and metastasis. By studying the effects of a transfected cell cycle defective (CK-) …
