Therapeutic PCL scaffold for reparation of resected osteosarcoma defect.

Osteosarcomas are highly malignant tumors, which develop rapid growth and local infiltration, inducing metastases that spread primarily in the lung. Treatment of these tumors is mainly based on pre- and post-operative chemotherapy and surgery of the primary tumor. Surgical resection though, generates bone defects.

Coupled delivery of imatinib mesylate and doxorubicin with nanoscaled polymeric vectors for a sustained downregulation of BCR-ABL in chronic myeloid leukemia.

In this work, we have investigated the potential benefits of combining biodegradable pH sensitive core-shell PCL NPs loaded with IM and enzyme sensitive polyelectrolyte complexes (PECs) loaded with doxorubicin (DOX). Our in vitro studies confirmed the excellent antileukemic activity of dual drug loaded nanoparticles on CML cells. As compared with a drug alone, co-treatment with IM and DOX loaded in nanoparticles allowed a sustained downregulation of BCR-ABL and significant CML stem cell death.

Microdroplet-based multiplex PCR on chip to detect foodborne bacteria producing biogenic amines.

The development of fast, reliable and culture-independent molecular tools to detect bacteria producing biogenic amines deserves the attention of research and ultimately of the food industry in order to protect consumers' health. Here we present the application of a simple, low-cost, fast and sensitive method to perform microdroplet-based multiplex PCR, directly on a food matrix, for the simultaneous detection of bacterial genes involved in biogenic amine biosynthesis. After inoculating wine with Lactobacillus brevis IOEB 9809, cell lysis and DNA amplification are performed in one single step, without preliminary nucleic acid extraction or purification treatments.
