Insular gliomas: a surgical reappraisal based on a systematic review of the literature.

Insular gliomas are heterogeneous lesions whose management presents multiple challenges for their tendency to affect young patients in good neurological and cognitive conditions, their deep anatomic location and proximity with critical functional and vascular structures. The appropriate management of insular gliomas requires a multidisciplinary evidence-centred teamwork grounded on the best anatomic, neurophysiological and oncological knowledge. The present study provides a reappraisal of the management of ...

D-retro-enantiomer of Quorum Sensing Peptides-Modified Polymeric Micelles for Brain Tumor Targeted Drug Delivery.

In comparison to other tumors, various barriers such as the blood-brain barrier (BBB), enzymatic barriers and the blood-brain tumor barrier (BBTB) severely impede the successful treatment of glioma. Peptide ligands were frequently used as targeting moieties to mediate brain tumor targeted drug delivery. LWSW (SYPGWSW) is a recently reported quorum sensing peptide which is able to efficiently cross the BBB. Even though the linear LWSW traverses the BBB in vitro, its' in vivo targeting ability has been greatl...

Isolation of Phenotypically-Distinct Cancer Cells Using Nanoparticle-Mediated Sorting.

Isolating subpopulations of heterogeneous cancer cells is an important capability for the meaningful characterization of circulating tumor cells at different stages of tumor progression and during epithelial to mesenchymal transition (EMT). Here, we describe a two-dimensional separation approach that yields phenotypically-distinct subpopulations of cancer cells. Magnetic nanoparticles coated with antibodies against the epithelial cell adhesion molecule (EpCAM) are used to enrich cancer cells in a microfluid...

Simultaneous separation and washing of non-magnetic particles in an inertial ferrofluid/water co-flow.

Magnetic fluids (e.g., paramagnetic solutions and ferrofluids) have been increasingly used for label-free separation of non-magnetic particles in microfluidic devices. Their biocompatibility, however, becomes a concern in high-throughput or large-volume applications. One way to potentially resolve this issue is re-suspending the particles that are separated in a magnetic fluid immediately into a biocompatible buffer. We demonstrate herein the proof-of-principle of the first integration of negative magnetoph...

Nanoscale Junction Formation by Gas-Phase Monolayer Doping.

A major challenge in transistor technology scaling is the formation of controlled ultra-shallow junctions with nanometer-scale thickness and high spatial uniformity. Monolayer doping (MLD) is an efficient method to form such nanoscale junctions, where the self-limiting nature of semiconductor surfaces is utilized to form adsorbed monolayers of dopant-containing molecules followed by rapid thermal annealing (RTA) to diffuse the dopants to a desired depth. Unlike ion implantation, the process does not induce ...

Controlled Release of Naringin in Metal-Organic Frameworks (MOFs) Loaded Mineralized Collagen Coating to Simultaneously Enhance Osseointegration and Antibacterial Activity.

Two important goals in orthopedic implants research are to promote osseointegration and prevent infection. However, much of previous efforts have been paid on the design of coatings either to enhance osseointegration while ignoring antibacterial activity or vice versa, to prevent infection while ignoring bone integration. Here, we designed a multifunctional mineralized collagen coating on titanium with the aid of metal-organic frameworks (MOFs) nanocrystals to control the release of naringin, a Chinese herb...

Elucidation of the Oxygen Surface Kinetics in a Coated Dual-Phase Membrane for Enhancing Oxygen Permeation Flux.

The dual-phase membrane has received much attention as the solution to the instability of the oxygen permeation membrane. It has been reported that the oxygen flux of the dual-phase membrane is greatly enhanced by the active coating layer. However, there has been little discussion about the enhancement mechanism by surface coating in the dual-phase membrane. This study investigates the oxygen flux of Ce0.9Gd0.1O2-δ-La0.7Sr0.3MnO3±δ (GDC 80 vol.%/LSM 20 vol.%) composite membrane depending on the oxygen pa...

The Challenge of Overcoming Antibiotic Resistance: An Adjuvant Approach?

Antibiotic resistance is one of the greatest current threats to human health, and without significant action we face the chilling prospect of a world without effective antibiotics. Although continued effort toward the development of new antibiotics, particularly those with novel mechanisms of action, remains crucial, this alone probably will not be enough to prevail, and it is imperative that additional approaches are also explored. One such approach is the identification of adjuvants that augment the activ...

A Fluorescent Split Aptamer for Visualizing RNA-RNA Assembly In Vivo.

RNA-RNA assembly governs key biological processes and is a powerful tool for engineering synthetic genetic circuits. Characterizing RNA assembly in living cells often involves monitoring fluorescent reporter proteins, which are at best indirect measures of underlying RNA-RNA hybridization events and are subject to additional temporal and load constraints associated with translation and activation of reporter proteins. In contrast, RNA aptamers that sequester small molecule dyes and activate their fluorescen...
