Major obstacles to the successful treatment of gliolastoma multiforme are mostly related to the acquired resistance to chemotherapy drugs and, after surgery, to the cancer recurrence in correspondence of residual microscopic foci. As innovative anticancer approach, low-intensity electric stimulation represents a physical treatment able to reduce multidrug resistance of cancer and to induce remarkable anti-proliferative effects by interfering with Ca and K homeostasis and by affecting the organization of the mitotic spindles. However, to preserve healthy cells, it is utterly important to direct the electric stimuli only to malignant cells. Read More

All tissues are surrounded by a mixture of noncellular matrix components, that not only provide physical and mechanical support to cells, but also mediate biochemical signaling between cells. The extracellular matrix (ECM) of endothelial cells, also known as the perivascular matrix, forms an organ specific vascular niche that orchestrates mechano-, growth factor, and angiocrine signaling required for tissue homeostasis and organ repair. This concise review describes how this perivascular ECM functions as a signaling platform and how this knowledge can impact the field of regenerative medicine, for example, when designing artificial matrices or using decellularized scaffolds from organs.

Two-dimensional (2D) black phosphorus (BP) has been attracting ever-growing interest due to its unique band structure, but suffers from low ambient stability owing to its high reactivity to oxygen. Covalent functionalization has been demonstrated to passivate the reactive BP effectively, however the reported covalent functionalization methods are quite limited to aryl diazonium and nucleophilic additions affording P-C and P-O-C single bonds, for which the retaining of one unpaired electron in the Group-VA phosphorus atom hampers the passivation effect. Herein, we report for the first time covalent azide functionalization of BP nanosheets (BPNSs), leading to significant enhancement of the ambient stability of BP as confirmed by UV-vis spectroscopic studies.

The UzcRS two-component system in Caulobacter crescentus mediates widespread transcriptional activation in response to the metals U, Zn and Cu. Unexpectedly, a screen for mutations that affected the activity of the UzcR-regulated urcA promoter (P ) revealed four previously uncharacterized proteins whose inactivation led to metal-independent induction of P . Using molecular genetics and functional genomics, we find that these auxiliary regulators control P expression by modulating the activity of UzcRS through distinct mechanisms. Read More

Photoactive molecules enable much of modern biology and biochemistry - a vast library of fluorescent chromophores is used to track and label cellular structures and macromolecules. However, photochemistry is better-known to the synthetic or physical organic chemist as a "light switch" that turns on unusual excited-state reactivity, isomerization, or dynamic adjustment of structure. This review details a rapidly growing approach to bio-photochemistry that uses low-energy near-IR wavelengths not only for imaging, but for close spatial control over chemical switching events in biosystems.

A plant's induction of secondary defenses helps to decrease herbivore damage by changing resource quality. While these chemical or physical defenses may directly decrease herbivory, they can also have indirect consequences. In a tritrophic system consisting of a plant, an insect herbivore, and an insect pathogen, plant based trait-mediated indirect effects (TMIEs) can alter host-pathogen interactions and, thereby, indirectly affect disease transmission.
