Exploring Cancer Metabolic Reprogramming through Molecular Imaging
The inclusion of oncogene-driven reprogramming of energy metabolism within the list of cancer hallmarks (Hanahan and Weinberg, Cell 2000, 2011) has provided major impetus to further investigate the existence of a much wider metabolic rewiring in cancer cells, which not only includes deregulated cellular bioenergetics, but also encompasses multiple links with a more comprehensive network of altered biochemical pathways. This network is currently held responsible for redirecting carbon and phosphorus fluxes through the biosynthesis of nucleotides, amino acids, lipids and phospholipids and for the production of second messengers essential to cancer cells growth, survival and invasiveness in the...
Molecular Mechanisms in Pulmonary Hypertension and Right Ventricle Dysfunction
Pulmonary hypertension (PH) is a disorder of the pulmonary vasculature defined by increased mean pulmonary arterial pressure (mPAP) leading to right ventricle (RV) hypertrophy and dysfunction, right-sided heart failure and ultimately death. PH is a common complication of chronic lung diseases (CLD) including idiopathic pulmonary fibrosis (IPF) or chronic obstructive pulmonary disease (COPD) where it is classified as Group 3 PH by the WHO. It can also be associated with cardiovascular conditions such as left-heart disease (classified as Group 2 PH) or appear on its own as pulmonary arterial hypertension (PAH) and classified as Group1 PH. In all of these cases the diagnosis of pulmonary hypertension is strongly associated with increased morbidity and mortality. The focus of this Research Topic is to enhance our understanding of the mechanisms that contribute to the pathophysiology of pulmonary hypertension and right ventricle hypertrophy.
X-Ray Phase-Contrast Tomography
X-ray imaging is a corner stone of breast cancer diagnosis. By exploiting the phase shift of X-rays rather than their attenuation, phase-contrast tomography has the potential to dramatically increase the visibility of small and low contrast features, thus leading to better diagnosis. This thesis presents research on the first synchrotron-based project developing a clinical phase-contrast breast computed tomography (CT) setup at Elettra, the Italian Syncrotron Radiation Facility. This book includes a comprehensive theoretical background on propagation-based phase-contrast imaging, exploring and extending the most recent image formation models. Along with theory, many practical implementation ...
Sex Ecologies
The first compendium of writing and art to present the case for the role of sex in environmental and social justice. Sex Ecologies explores pleasure, affect, and the powers of the erotic in the human and more-than-human worlds. Arguing for the positive and constructive role of sex in ecology and art practice, these texts and artistic research projects attempt nothing short of reclaiming the sexual from Western erotophobia and heteronormative narratives of nature and reproduction. The artists and writers set out to examine queer ecology through the lens of environmental humanities, investigating the fluid boundaries between bodies (both human and nonhuman), between binary conceptions of natur...
