Description: 

My LINK network science group (www.linkgroup.hu) is concentrating on the analysis of the topology and dynamics of biological networks, including protein structure networks, proteim-protein interaction networks, signaling networks and chromatin networks. We have recently developed a network dynamics tool, Turbine (www.turbine.linkgroup.hu), which is able to discover the attractor structure of dynamic systems and predict target sets of multi-target drug candidates shifting the cell from a disease state to a healthy state. We have established a biotech startup (www.dzzom.com) to explore the applications of this method. In my lecture I will also summarize my recent concept on plasticity-rigidity cycles forming a general adaptation mechanism, and will show its applications in drug design.

Description: 

The BIOTEC Forum 2014 "Biomechanics across scales - molecules, cells, tissues" brings together international and local experts in the areas of biomechanics, biophysics, cell and developmental biology. The focus will be on biomechanical processes that are at work on different scales. The goal is to present current developments in this area and to identify commonalities and differences of biomechanical processes independent of scale. Specific topics covered include molecular force generation, the cytoskeleton, cell mechanics, mechanonsensitivity and tissue mechanics - a spectrum that reflects the expertise of biomechanics research in Dresden.

Starting in 2007, the BIOTEC Forum has become an annual open meeting, discussing hot topics in one or more of the research areas represented at the BIOTEC Center of the TU Dresden. The format of the meeting is such that internationally renowned speakers at the forefront of their respective research fields will present and discuss recent scientific advances. The meeting is fully open to local and external scientists, with no conference fee being taken. Own contributions can be made within a postersession.

Registration and abstract submission for the BIOTEC Forum is now open.
There is no registration fee for the conference! Register here

Deadline for abstract submission is end of October, registration is open until mid November. Amongst the abstract submissions we will select several for contributed short talks in addition to the invited speakers' talks.

We plan a conference get-together on Monday evening after a stroll over the christmas market - this is a great opportunity to mingle with the speakers in an informal setting.

Please do also register if you only want to attend the conference and don't want to submit an abstract.

Description: 

Michele De Luca has dedicated most of his scientific activities to translational medicine. He is recognised as a leading scientist in squamous epithelial stem cell biology and has been a driving force in the development of epithelial stem cell-mediated cell therapy and gene therapy. Following on early work on the use of human epidermal stem cell cultures in life-saving treatment of massive full-thickness burns and in repigmentation of stable vitiligo and piebaldism by keratinocyte/melanocyte co-colture, he was first to establish human urethral stem cell culture aimed at urethral regeneration in posterior hypospadias (N. Engl. J. Med. 1990). He and his principal collaborator, Graziella Pellegrini, developed human limbal stem cell culture (J. Cell Biol. 1999) for corneal regeneration in patients with severe limbal stem cell deficiency (Lancet 1997; N. Engl. J. Med 2010). This treatment leads to recovery of normal vision and is now used worldwide. De Luca is also pioneering ex-vivo epithelial stem cell-mediated gene therapy for genetic skin diseases. He coordinates the first successful clinical trial to treat junctional epidermolysis bullosa (Nat. Med. 2006; Stem Cell Rep. 2014). De Luca has characterised molecular mechanisms regulating long term proliferative potential, clonal evolution and self-renewal of epithelial stem cells. In particular, he shed light on the role of p63 (different isoforms) and c/EBPδ in regulating the proliferative potential and the self-renewal of human corneal stem cells, respectively (PNAS 2001, 2005; J. Cell Biol. 2007). Notably, his work demonstrated that the clinical success of limbal stem cultures is dependent on a discrete number of stem cells identified as holoclones expressing the ΔNα isoform of p63 (N. Engl. J. Med.  2010, TMM 2011).
Michele De Luca is internationally recognised for his experience in stem cell therapy. He contributed to two reports by the International Society for Stem Cell Research, dealing with new guidelines for responsible translational stem cells research (Cell Stem Cell 2008, 2009).

Description: 

In the last few years, there has been a burst in the study and conceiving of new devices for the generation and manipulation of electromagnetic field at the nanoscale, where radiation-matter interaction is strongly enhanced. Several fabrication methods are now available for material preparation and nano-structuring, but only few of them can ensure the stringent design control needed for the effective and reproducible device behavior.
We report, herein, novel processes of micro and nanofabrication techniques for several applications in different research fields.
During the lecture it will be presented selected topics from our research activity. In particular it will be highlighted the results on single molecule detection, Plasmon Polariton conversion to Hot electrons and direct imaging of DNA.

Description: 

What do you think about the current state of academic publishing and communication? Does the way researchers make their results public serve well enough? Do you experience pressure to be interesting and make a choice between ‘exciting’ and ‘honest’ data?

For years, we have felt that there has to be a more efficient and fairer way to organize scientific communication. As scientists, we are frustrated with the dominance of the impact factor and how peer review is conducted. That is why someone has to take a step toward realizing a new vision.  Last year we founded ScienceOpen. ScienceOpen is a new community-based Open Access publisher and research network from Berlin and Boston. With the initiative ScienceOpen, we would like to change the current scientific publishing culture and have therefore created a concept of immediate publication followed by transparent evaluation (https://www.scienceopen.com/home). Additionally, the ScienceOpen platform enables reviewing and commenting on over 1 million Open Access publications.

We are deeply committed to developing a different kind of publishing.
