Title: Novel biophotonics for imaging through complex biological systems

Location: Computer Science Department, room A115 (ground floor), Voutes

Time: 16:00

Language: English

Abstract
Modern advances of photonic technologies and their application in
biomedical research and clinical practice have raised immense interest
in the scientific community. It is only recently that the Nobel Prize
was awarded for the invention of Nanoscopy and breaking one of the
fundamental laws of optics. We are now able to observe and quantify
biology with resolutions down to the nanometer scale. At the same time
the field of in vivo molecular imaging is being widely recognized as one
of the most influential for translational research, transforming health
care and personalized approaches for diagnosis and therapy. In that
respect, current tools in biophotonics have offered a new avenue for
exploration of biological function, detection and treatment of disease
in living organisms and systems.
Methods that provide three dimensional microscopic images such as
Optical Projection Tomography (OPT) and Light Sheet Fluorescence
Microcopy (LSFM) or Selective Plane Illumination Microscopy (SPIM) have
found their way into biology labs due to their advantages compared to
traditional methods such as confocal microscopy in imaging larger
samples. On the other hand, recent advances in optoacoustic imaging have
allowed to image in so far non-accessible regimes with unprecedented
resolutions, based on the use of light for the illumination and
production of ultrasonic waves. These developments have provided the
means for performing high resolution, quantitative, volumetric and
dynamic studies in live specimens ranging from imaging the development,
to imaging cancer, the function of the cardiovascular system, to
neuroimaging, aging and associated diseases to chemotherapeutic
interventions and drug delivery. Moreover, they offer to users unique
capabilities for basic studies and most importantly for detecting and
treating major diseases in clinical practice alongside or replacing
established methodologies .
However, the use of photonic technologies, even though exhibiting very
important advantages and offering insight in new bio-molecular
functions, still comes with significant disadvantages associated with
the diffusive transport of light in biological tissue. Radically new
technologies though are being developed for the production, manipulation
and delivery of light radiation, based on adaptive wavefront control and
shaping to compensate for light diffusion and overcome the limitations
of conventional microscopy and obtain high resolution images deeper than
a few micrometers.
These very exciting discoveries and advances in biophotonic technologies
have now starting to revolutionize the way biological research is
performed. The ability to perform in vivo imaging in scales ranging from
microscopy to macroscopy at depth from a few micrometers to several
centimeters opens up the possibility to shift biological observation
towards longitudinal noninvasive studies of dynamic phenomena inside
whole animals and help understand better human development, function and
disease.

Title: “Artificial Photosynthesis and synthetic approaches with
porphyrin-hybrid derivatives”

Location: Computer Science Department, room A115 (ground floor), Voutes

Time: 16:00

Language: English

Abstract
Natural processes of photosynthesis have increasingly inspired the
fabrication of nanostructured molecular materials with advanced
light-harvesting and electron-transfer features. [1-6] In this context,
supramolecular chemistry allows diverse and disparate molecular building
blocks to be amalgamated into highly ordered architectures. These mimics
the key functions of the photosynthetic reaction center; light
harvesting, charge separation, charge transport, and catalysis. [7,8]
Porphyrinoids, the basic building block of chlorophylls, have emerged as
an exceptional class of light harvesters and electron donors in such
supramolecular electron donor-acceptor hybrids [9-12].

Title: “Blood rheology and flow characteristics in the macro- and
micro-scale”.

Location: Computer Science Department, room A115 (ground floor), Voutes

Time: 16:00

Language: English

Abstract
Blood can be considered as a two phase, non-Newtonian fluid, and its
flow characteristics, in particular in the microvasculature, are
affected by this fact. To a large degree the complex mechanical nature
of the fluid is due to red blood cell (RBC) aggregation phenomenon,
which is found intense in a number of pathological conditions. The time
and flow-dependent characteristics of the aggregated structures
developed in blood affect its mechanical properties, and can be examined
by various techniques. In this talk the influence of RBC aggregation on
blood rheology at the macroscale will be discussed first. It will be
shown that secondary aggregation characteristics may play a key role in
explaining the behaviour of the mechanical properties of the fluid under
various flow conditions. Secondly, the influence of the RBC aggregation
phenomenon on the flow characteristics for microscale bifurcating
geometries, resembling the microvasculature, will be discussed. It will
be illustrated that the aggregation phenomenon, apart from the flow
characteristics, affects the aggregate distribution in the bifurcation
in a counterintuitive manner, i.e. the smaller aggregates appear in
regions of lower shear, as opposed to the general understanding that
aggregation increases at the specific shear conditions. Such behaviour
is explained when considering the spatial distribution of aggregates in
conjunction to the velocity field developed in the parent channel
branches. Finally, an attempt to predict the local viscosity in the
microchannels will be described based on existing constitutive equations
for blood.

Από το 'κακό μάτι' στις ενεργειακές θεραπείες: μια εθνογραφική προσέγγιση των πρακτικών εναλλακτικής ιατρικής στην Ελλάδα της κρίσης.
Ευγενία Ρούσσου, Συνεργαζόμενη Ερευνήτρια, Κέντρο Έρευνας της Ανθρωπολογίας, Νέο Πανεπιστήμιο Λισαβόνας
Στην σημερινή Ελλάδα, ο αριθμός των ατόμων που καταφεύγουν σε ενεργειακές θεραπείες για να αντιμετωπίσουν προβλήματα όσον αφορά στην υγεία και την ευημερία τους συνεχίζει να αυξάνεται. Από γιόγκα και διαλογισμό ως (νεο)σαμανισμό και θεραπευτικές πρακτικές που βασίζονται σε πνευματικές παραδόσεις της Ασίας, της Βραζιλίας και της Αφρικής, υπάρχουν πλέον πολλές επιλογές ως προς το ποια θεραπευτική πρακτική μπορεί κανείς να υιοθετήσει στην καθημερινότητά του, συμπεριλαμβανομένης και της πιο ‘παραδοσιακής’ θεραπείας ενάντια στο ‘κακό μάτι’. Βασισμένη σε ανθρωπολογική έρευνα που έχει διεξαγάγει η ομιλήτρια στο Ρέθυμνο και την Αθήνα, η διάλεξη θα επικεντρωθεί στην παρουσίαση του πλουραλιστικού αυτού κοινωνικοπολιτισμικού πλαισίου των θεραπευτικών πρακτικών της λεγόμενης εναλλακτικής ιατρικής και τη σύνδεσή του με τις κοινωνικο-οικονομικές προκλήσεις που αντιμετωπίζουν σήμερα οι χώρες της Μεσογείου. Στόχος είναι να δοθεί μια εθνογραφική εικόνα για τον ποικιλόμορφο, πολυδιάστατο και πολυπολιτισμικό χαρακτήρα των εναλλακτικών θεραπειών στην Ελλάδα και να αναλυθεί το πώς ακόμα και πιο ‘παραδοσιακές’ θεραπευτικές πρακτικές, όπως αυτή του ξεματιάσματος, έχουν αρχίσει να προσαρμόζονται εκ νέου και να υποβάλλονται σε μια διαδικασία μεταμόρφωσης, προκειμένου να προσαρμοστούν στα νέα δεδομένα διαχείρισης της ιδιωτικής και δημόσιας υγείας στην Ελλάδα της κρίσης.

Title: “Yielding and confinement of a yield-stress fluid”

Location: Computer Science Department, room A115 (ground floor), Voutes

Time: 16:00

Language: English

Abstract

Yield-stress fluids are soft solids when subjected to a shear stress lower than their yield stress, but flow in response to higher stresses.
I will discuss the process by which Carbopol, a model yield-stress fluid, changes from solid-like to fluid-like when it starts to flow in a
vertical pipe. In a rough-walled pipe, the yielding involves a long transition with several steps: elastic deformation, the onset of wall
slip, yielding at the wall, and finally a steady-state plug flow that is well-described by the predictions of the Herschel-Bulkley model. I will then discuss experiments on the flow of Carbopol confined to square microchannels with sides ranging from 500 µm down to 50 µm. In the
larger channels, measured velocity profiles agree well with simulations based on the bulk rheology of the Carbopol and the Herschel-Bulkley model. In contrast, in microchannels smaller than 150 µm the velocity profiles could not be fitted by a model with a finite yield stress, but instead were described by a power-law model with zero yield stress. I will discuss the vanishing of the yield stress in terms of the effect of confinement on the microstructure of the Carbopol.
