Diagnosis of intrahepatic cholangiocarcinoma with CEUS.

Intrahepatic cholangiocarcinoma (ICC) is a rare, heterogeneous, highly lethal tumor of the biliary tract. Due to the lack of effective treatments, an early identification of ICC is essential to achieve the best outcome in terms of therapy and prognosis aiming for a curative intent. ICC may arise on a normal liver or with an underlying liver disease, making the diagnosis more difficult and complex.

Liposome-Mediated Chemotherapeutic Delivery Is Synergistically Enhanced by Ternary Lipid Compositions and Cationic Lipids.

Most small molecule chemotherapeutics must cross one or more cellular membrane barriers to reach their biochemical targets. Owing to the relatively low solubility of chemotherapeutics in the lipid membrane environment, high doses are often required to achieve a therapeutic effect. The resulting systemic toxicity has motivated efforts to improve the efficiency of chemotherapeutic delivery to the cellular interior.

Current state of U.S. Food and Drug Administration regulation for cellular and gene therapy products: potential cures on the horizon.

Cellular & Gene Therapies (CGTs) are complex products, which have been key foci of the International Society for Cell & Gene Therapy (ISCT). For this ISCT North American Legal & Regulatory Affairs Committee review publication, CGTs include but are not limited to somatic cell-based therapies, pluripotent cell-derived cell-based therapies, gene- or non-gene-modified or gene edited versions of these cell-based therapies, in vivo gene therapies, organ/tissue engineered products, and relevant combination products. These products are regulated by the Food and Drug Administration (FDA) in the United States.

Phase-Separated Liposomes Enhance the Efficiency of Macromolecular Delivery to the Cellular Cytoplasm.

Introduction: From viruses to organelles, fusion of biological membranes is used by diverse biological systems to deliver macromolecules across membrane barriers. Membrane fusion is also a potentially efficient mechanism for the delivery of macromolecular therapeutics to the cellular cytoplasm. However, a key shortcoming of existing fusogenic liposomal systems is that they are inefficient, requiring a high concentration of fusion-promoting lipids in order to cross cellular membrane barriers.
