Thoracic fluid accumulation is one of the significant and early-stage manifestations of fatal diseases, such as lung-cancer, liver-failure and congestive heart-failure. Currently, computational-tomography (CT)-Scan is the most widely used tool for the detection of thoracic fluid. Yet, it is unable to detect small amounts of fluid, has ionizing radiation and lacks mobility. On the other hand, microwave imaging systems have emerged as an accurate and portable complementary diagnostic tool. However, there is a lack of a complete clinical platform that can fulfill the requirements of accurate and reliable imaging...

Antonio Cigliano, Jingxiao Wang, Xin Chen, Diego F Calvisi
Cholangiocarcinoma (CCA) is an emerging cancer entity of the liver, associated with poor outcome and characterized by resistance to conventional chemotherapeutic treatments. In the last decade, many signaling pathways associated with CCA development and progression have been identified and are currently under intense investigation. Cumulating evidence indicates that the Notch cascade, a highly-conserved pathway in most multicellular organisms, is a critical player both in liver malignant transformation and tumor aggressiveness, thus representing a potential therapeutic target in this pernicious disease...

REVIEW
A D Jones, J C Wilton
Liver resection remains the cornerstone of curative treatment for hepatocellular carcinoma and colorectal cancer liver metastases. Its success is dependent upon the extent of resection achieved. To this end, intra-operative imaging techniques have been experimented with to aid the surgeon. Fluorescence guided surgery (FGS) utilises the properties of near infrared light emitting molecules to identify malignant tissue, enabling the surgeon to maximise resection of diseased tissue and minimise collateral damage...

Hanna Kędzierska, Agnieszka Piekiełko-Witkowska
SR and hnRNP proteins were initially discovered as regulators of alternative splicing: the process of controlled removal of introns and selective joining of exons through which multiple transcripts and, subsequently, proteins can be expressed from a single gene. Alternative splicing affects genes involved in all crucial cellular processes, including apoptosis. During cancerogenesis impaired apoptotic control facilitates survival of cells bearing molecular aberrations, contributing to their unrestricted proliferation and chemoresistance...

Poly(ADP-ribose) polymerase-1 (PARP-1) is a nuclear enzyme that plays a critical role in diverse cellular functions, such as DNA damage detection and repair, transcriptional regulation and cell death. Furthermore, PARP-1 has emerged as a key player in the pathogenesis of multiple inflammatory diseases and has become a promising target for the treatment of cardiovascular disorders, neurodegenerative diseases and cancer. An increasing body of evidence has linked alterations in the expression levels of PARP-1, enzymatic activity and presence of polymorphism to gastrointestinal malignancies, including oesophageal, gastric, pancreas, liver and colorectal cancers...

An Active Breathing Coordinator (ABC) can be employed to induce breath-holds during CT imaging and radiotherapy of lung, breast and liver cancer, and recently during lung cancer MRI. The apparatus measures and controls respiratory volume, hence subject lung volume reproducibility is its principal measure of effectiveness. To assess ABC control quality, the intra-session reproducibility of ABC-induced lung volumes was evaluated and compared with that reached by applying the clinical standard of operator-guided self-sustained breath-holds on healthy volunteers during MRI...

PURPOSE: Therapeutic nanoparticles are designed to deliver their drug payloads through enhanced permeability and retention (EPR) in solid tumors. The extent of EPR and its variability in human tumors is highly debated and has been proposed as an explanation for variable responses to therapeutic nanoparticles in clinical studies. EXPERIMENTAL DESIGN: We assessed the EPR effect in patients using a 64Cu-labeled nanoparticle, 64Cu-MM-302 (64Cu-labeled HER2-targeted PEGylated liposomal doxorubicin), and imaging by Positron Emission Tomography/Computed Tomography (PET/CT)...

BACKGROUND: Hepatocellular carcinoma is the most common liver neoplasm, the sixth most common cancer worldwide, and the third most common cause of cancer mortality. Moreover, its incidence has increased dramatically in the past decade. While surgical resection and liver transplantation are the main curative treatments, only around 20% of people with early hepatocellular carcinoma may benefit from these therapies. Current treatment options for unresectable hepatocellular carcinoma include various ablative and transarterial therapies in addition to the drug sorafenib...
