Unraveling cartilage degeneration through synergistic effects of hydrostatic pressure and biomimetic temperature increase

Dominique Pioletti, Peyman Karami, Naser Nasrollahzadeh Mamaghani, Theofanis Stampoultzis, Yanheng Guo, Vijay Kumar Rana

Cartilage degeneration, typically viewed as an irreversible, vicious cycle, sees a significant reduction in two essential biophysical cues: the well-established hydrostatic pressure (HP) and the recently discovered transient temperature increase. Our study ...

Different priming states of synaptic vesicles underlie distinct release probabilities at hippocampal excitatory synapses

Maria Reva

A stunning example of synaptic diversity is the postsynaptic target cell-type-dependent difference in synap-tic efficacy in cortical networks. Here, we show that CA1 pyramidal cell (PC) to fast spiking interneuron (FSIN) connections have 10-fold larger rel ...

A data-driven polynomial approach to reproduce the scar tissue outgrowth around neural implants

Silvestro Micera

Despite the huge complexity of the foreign body reaction, a quantitative assessment over time of the scar tissue thickness around implanted materials is needed to figure out the evolution of neural implants for long times. A data-driven approach, based on ...

Progestins used for hormonal contraception in Switzerland: study of their effects on the breast epithelium

Marie Shamseddin

Breast cancer is the most commonly diagnosed cancer and the most common cause of cancer death among women. Hormones have been shown to have a key role in breast development and carcinogenesis. Repeated activation of progesterone receptor (PR) signaling as ...

Engineered acellular collagen scaffold for endogenous cell guidance, a novel approach in urethral regeneration

Jeffrey Alan Hubbell, Peter Frey, Hans Mattias Larsson, Elif Vardar, Kalitha Pinnagoda, Ganesh Vythilingam

The treatment of congenital malformations or injuries of the urethra using existing autologous tissues can be associated with post-operative complications. Using rat-tail collagen, we have engineered an acellular high-density collagen tube. These tubes wer ...

Antagonistic roles of Notch and p63 in controlling mammary epithelial cell fates

Cathrin Brisken, Maryse Fiche

The breast epithelium has two major compartments, luminal and basal cells, that are established and maintained by poorly understood mechanisms. The p53 homolog, p63, is required for the formation of mammary buds, but its function in the breast after birth ...

Design and Psychophysical Evaluation of a Tactile Pulse Display for Teleoperated Artery Palpation

Hannes Bleuler, Roger Gassert, Philippe Rétornaz, Laura Santos Carreras, Kaspar Leuenberger

During traditional open procedures, surgeons directly palpate tissues before dissecting them. In this way, they can avoid the accidental damage of hidden arteries that can lead to fatal hemorrhage. New Minimally Invasive Surgical (MIS) techniques progressi ...

Ultrasound Tomography with Learned Dictionaries

Martin Vetterli, Pascal Frossard, Ivana Jovanovic, Ivana Tosic

We propose a new method for imaging sound speed in breast tissue from measurements obtained by ultrasound tomography (UST) scan- ners. Given the measurements, our algorithm finds a sparse image representation in an overcomplete dictionary that is adapted t ...

Poisson Reduction by Distributions

Tudor Ratiu, Madeleine Jotz

It is shown that the singular Poisson reduction procedure can be improved for a large class of situations. In addition, Poisson reduction of orbit type manifolds is carried out in detail. ...

Inverse problems in acoustic tomography : theory and applications

Ivana Jovanovic

Acoustic tomography aims at recovering the unknown parameters that describe a field of interest by studying the physical characteristics of sound propagating through the considered field. The tomographic approach is appealing in that it is non-invasive and ...

Delivery of FGF-2 but not VEGF by encapsulated genetically engineered myoblasts improves survival and vascularization in a model of acute skin flap ischemia

Patrick Aebischer

Stimulating angiogenesis by gene transfer approaches offers the hope of treating tissue ischemia which is untreatable by currently practiced techniques of vessel grafting and bypass surgery. Vascular endothelial growth factor (VEGF) and basic fibroblast gr ...
