|Bayesian Parameter Estimation for Systems Biological Models of Dynamic Cellular Networks|
Jarad Niemi, Lingchong You and Mike West
Dynamic cellular networks determine production of proteins in the cells in our body. The Rb-E2F network is a key example: it controls cell cycle, proliferation and degradation - a key network in almost all cancers. We develop statistical models of such single-cell processes - fine-time scale dynamic network models. Model estimation requires informative priors and custom Metropolis proposals.
|Hyperbaric Bioreactors use with Yarrowia Lipolytica Cultures: Cellular Adaptation to Hyperbaric Conditions|
Marlene Lopes, Nelma Gomes, Manuel Mota, Isabel Belo
In this work, a pressurized bioreactor was used for Y. lipolytica batch cultivation under increased air pressure from 1 bar to 6 bar. Cell growth was strongly enhanced by the pressure rise. The increase of oxygen availability caused the induction of the antioxidant enzyme SOD. The pre-growth of Y. lipolytica under increased pressure conditions did not affect the lipase production ability of the cells.
|Treatment of Highland Frogs from the Two Legged Stage with Homeopathically Prepared Thyroxin (10-11 – 10-21)|
Gerhard Lingg1, P. Christian Endler1,*, Michael Frass1, and Harald Lothaller2
For the experiment presented here, we used the same setup as for the initial multilaboratory study[1,2,3,4], but a special preparation process of the homeopathic drug involving dilution steps of 1: 50,000 and leading to thyroxin 10–11 – 10–21 was used.
|A high-throughput protein array-based approach |
Rachel Van Dyk, Claudia Kirisits, Paul Potter, Fook Tim Chew, Reinhard Hiller
Here we present a novel discovery-oriented high-throughput approach to the screening of allergen reactivates in crude biological extracts is presented using seafood allergens as an example. The CPGR workflow permits the effective screening of hundreds of putative allergens in parallel using minute amounts of patient serum and constitutes a cost-efficient allergen-specific antibody screening method for a routine diagnostic setting.
|Effects of cannabinoids on cholinergic-mediated contraction of human bronchi|
Stanislas Grassin Delyle, Emmanuel Naline, Amparo Buenestado, Charles Advenier, Philippe Devillier
The current study was performed to investigate the role of cannabinoid (CB) receptors on the cholinergic contraction of isolated human airways. Results obtained with WIN55,212-2 (CB1/CB2 agonist), JWH-133 (CB2 agonist) and CB receptor selective antagonists suggest that CB1-receptor stimulation inhibits the cholinergic contraction in human isolated bronchi through stimulation of prejunctional receptors, located to post-ganglionic cholinergic nerves.
|DISTRIBUTION OF SAa2,6GAL AND SAa2,3GAL LINKED SURFACE RECEPTORS IN HUMAN RESPIRATORY TRACT AND ASSOCIATION WITH INFLUENZA VIRUS REPLICATION|
Hsu, A.1,3, Grissell, T.1,3, Hansbro, P.2,3, Wark, PAB.1,3
To investigate the level of SAa2,6Gal and a2,3Gal linked receptors on human bronchial epithelial cells, and relate this to the ability of both human and avian influenza viruses to infect bronchial epithelial cells
|Accuwik® Ultra Membrane for the Direct Collection, Storage, and Efficient Rapid Release of Biological Samples for Clinical Diagnostics|
Galina Fomovska, Stephane Perreault, Richmond Lo, and Martin A. Smith
Poster data assesses use of Pall’s Accuwik Ultra membrane as a reliable tool for direct collection of clinical samples including saliva and plasma, enables stability during sample storage, and allows for rapid and efficient release of clinically relevant protein biomarkers suitable for diagnostic analyses.
|Expression of stress response protein GRP78 is associated with the development of castration-resistant prostate cancer|
Llana Pootrakul, Anirban P. Mitra, Ram H. Datar, Shan-Rong Shi, Jie Cai, Debra Hawes, Susan G. Groshen, Amy S. Lee, Richard J. Cote
This study investigated the role of the GRP78 in prostate cancer progression and the development of castration-resistant prostate cancer, where cancer cells continue to survive despite the stress of an androgen-starved environment.
|Biomarkers and Metabolomics: Practical Implication|
Vladimir V. Tolstikov
Current presentation is dedicated to case studies and illustrates diversity of the projects. Cases representing different projects combine the same analytical platform we utilize for metabolomics study of blood plasma and urine. While pattern recognition presents certain challenges but rather ones that can be resolved, identification of low abundant unknown biomarkers is critical for the field and offers significant technical challenge in spite of considerable progress in modern analytical techn
