Herein, we review innovative nanomedicine-based approaches for treating, preventing and diagnosing neurodegenerative diseases. We focus on nanoscale systems such as polymeric nanoparticles (NPs), liposomes, micelles and other vehicles (e.g. dendrimers, nanogels, nanoemulsions and nanosuspensions) for targeted delivery of bioactive molecules to the brain. To ensure maximum selectivity for optimal therapeutic or dia Read More

Neurodegenerative diseases, including Parkinson’s and Alzheimer’s, are a heterogeneous group of brain disorders characterized by the progressive degeneration of the structure and function of the central or peripheral nervous system. It is thought that the number of people affected by these pathologies will increase in future decades, particularly in the more economically developed countries, where the populations are experi Read More

Background: Traumatic brain injury (TBI) is the result of an external physical force to the head that harms the brain. TBI is a major public health problem worldwide and mainly results from falls, vehicle accidents and violence. Clinical problem: The management of TBI, causing a wide spectrum of possible health outcomes, has barely changed over the years as encouraging outcomes from many pre-clinical therapeutic Read More

This review focuses on the application of metal nanoparticles in the diagnosis and treatment of Alzheimer’s and Parkinson’s diseases. Metal nanoparticles present interesting physicochemical properties that can be applied to increase biomarker detection sensitivities in vitro and in vivo. Furthermore, these nanoparticles could be used in different strategies for the treatment of central nervous system diseases, particularly Read More

Background: Alzheimer’s disease (AD) has a dramatic impact on society. The therapeutic targets are located in the central nervous system (CNS), which limits the efficacy of drugs systemically administered: the blood-brain barrier (BBB) selectively allows the permeation of just a few kinds of molecules from the systemic circulation to the CNS. On the other hand, local administration routes to CNS are highly invasive. Methods: Read More

Targeting nanomedicine to brain tumors is hampered by the heterogeneity of brain tumors and the blood brain barrier. These represent the main reasons of unsuccessful treatments. Nanomedicine based approaches hold promise for improved brain tissue distribution of drugs and delivery of combination therapies. In this review, we describe the recent advancements and latest achievements in the use of nanocarriers, virus a Read More

Background: In vivo bioluminescence imaging has been used extensively for screening assays and for qualitative determination of localization of cells, in particular in cancer studies. Objective: In this review we show the potential of this noninvasive molecular imaging modality to investigate gene activity, dynamic processes, and translational disease processes, all under true in vivo conditions with the specific focus on brain. R Read More

Mass spectrometry imaging (MSI) can uniquely detect thousands of compounds allowing both their identification and localization within biological tissue samples. MSI is an interdisciplinary science that crosses the borders of physics, chemistry and biology, and enables local molecular analysis at a broad range of length scales: From the subcellular level to whole body tissue sections. The spatial resolution of some mass spectro Read More

The induction of immune tolerance towards self-antigens presents as a viable future strategy in the treatment of auto-immune diseases, including vasculitis and multiple sclerosis (MS). As specific targets are currently lacking for vasculitis due to incomplete understanding of the pathologies underlying this disease, current treatment options are based on modalities that induce general immune suppression. However, many im Read More

Osteosarcoma is the most frequent primitive malignant bone tumor affecting adolescents and young adults worldwide. The tumor exhibits aggressive growth in the primary site and readily metastasizes to other organs. There has been no significant improvement in the 5-year survival rate since the 1970s and the figure remains at 60–70%. In addition, the side effects of chemotherapeutic drugs and resistance to chemo Read More

Lung cancer is among the leading causes of cancer-related-death. Non-small cell lung cancer (NSCLC) is the most common form of lung cancer. More than 70% of NSCLC patients have locally advanced or metastatic disease in diagnosis stage, which are then being treated with platinum-based chemotherapy or epidermal-growthfactor- receptor (EGFR) inhibitors. Several molecules which target multiple ErbB receptors an Read More

Epidermal growth factor receptor (EGFR) as a transmembrane tyrosine kinase receptor frequently overexpresses in tumors with epithelial origin. The L2 domain from extracellular part of EGFR is involved in ligand binding and the blockage of this domain prevents activation of related signaling pathways. This study was aimed to develop a novel human scFv against EGFR L2 domain as a promising target for cancer therapy. The L Read More

Background: Formulations incorporating nanoparticles (NPs) are widely used to prolong drug release. In this regard, poly(lactide-co-glicolide) (PLGA) is often used in their preparation due to its high degree of biocompatibility and biodegradability. In the present study, morphine HCl is incorporated in PLGA-NPs and different preparation alternatives are evaluated for their effects on the properties, stability and capacity of encapsulati Read More
