Cannabinoid CB receptor expression in oligodendrocyte progenitors of the hippocampus revealed by the NG2-EYFP-knockin mouse.

Adult oligodendrocyte progenitor cells (OPCs) give rise to myelinating oligodendrocytes through life and play crucial roles in brain homeostasis and plasticity during health and disease. Cannabinoid compounds acting through CB receptors promote the proliferation and differentiation of OPCs and facilitate developmental myelination and myelin repair . However, CB receptor expression in adult OPCs has not been corroborated by anatomical studies and the contribution of this receptor population to the (re)myelination effects of cannabinoids remains a matter of debate.

Endocannabinoid signaling in brain diseases: Emerging relevance of glial cells.

The discovery of cannabinoid receptors as the primary molecular targets of psychotropic cannabinoid Δ -tetrahydrocannabinol (Δ -THC) in late 1980s paved the way for investigations on the effects of cannabis-based therapeutics in brain pathology. Ever since, a wealth of results obtained from studies on human tissue samples and animal models have highlighted a promising therapeutic potential of cannabinoids and endocannabinoids in a variety of neurological disorders. However, clinical success has been limited and major questions concerning endocannabinoid signaling need to be satisfactorily addressed, particularly with regard to their role as modulators of glial cells in neurodegenerative diseases.

Magnetization Reversal Process and Magnetostatic Interactions in FeCo/SiO/FeO Core/Shell Ferromagnetic Nanowires with Non-Magnetic Interlayer.

Nowadays, numerous works regarding nanowires or nanotubes are being published, studying different combinations of materials or geometries with single or multiple layers. However, works, where both nanotube and nanowires are forming complex structures, are scarcer due to the underlying difficulties that their fabrication and characterization entail. Among the specific applications for these nanostructures that can be used in sensing or high-density magnetic data storage devices, there are the fields of photonics or spintronics.

P2x7 receptors control demyelination and inflammation in the cuprizone model.

The contribution of P2x7 receptors to multiple sclerosis remains controversial, as both detrimental and beneficial effects resulting from P2x7 receptor loss-of-function have been reported in autoimmune models of the disease. Here we investigated the relevance of P2x7 receptors to de- and remyelination in the cuprizone model of T cell-independent myelin degeneration. Primary demyelination was induced by administration of 0.

Quality of life in elderly breast cancer patients with localized disease receiving endocrine treatment: a prospective study.

Purpose: In this paper we study the quality of life (QoL) of elderly breast cancer patients receiving endocrine treatment (ET). More QoL data on elderly patients treated with ET are needed. Our aims are to study QoL in early-stage breast cancer patients throughout the treatment period and compare the QoL of ET groups.

Inhibition of Casein Kinase 2 Protects Oligodendrocytes From Excitotoxicity by Attenuating JNK/p53 Signaling Cascade.

Oligodendrocytes are highly vulnerable to glutamate excitotoxicity, a central mechanism involved in tissue damage in Multiple Sclerosis (MS). Sustained activation of AMPA receptors in rat oligodendrocytes induces cytosolic calcium overload, mitochondrial depolarization, increase of reactive oxygen species, and activation of intracelular pathways resulting in apoptotic cell death. Although many signals driven by excitotoxicity have been identified, some of the key players are still under investigation.

Re-examining the potential of targeting ABHD6 in multiple sclerosis: Efficacy of systemic and peripherally restricted inhibitors in experimental autoimmune encephalomyelitis.

α/β-Hydrolase domain-containing 6 (ABHD6) contributes to the hydrolysis of the major endocannabinoid 2-arachidonoylglycerol (2-AG) in the central nervous system (CNS) and in the periphery. ABHD6 blockade has been proposed as novel strategy to treat multiple sclerosis (MS), based on the observation that the inhibitor WWL70 exerts protective anti-inflammatory effects in experimental autoimmune encephalomyelitis (EAE). According to recent data, WWL70 exhibits off-target anti-inflammatory activity in microglial cells and the potential of ABHD6 as drug target in MS remains controversial.

Deregulation of the endocannabinoid system and therapeutic potential of ABHD6 blockade in the cuprizone model of demyelination.

Multiple sclerosis (MS) is a chronic demyelinating disease of unknown etiology in which tissue pathology suggests both immune-dependent attacks to oligodendroglia and primary oligodendrocyte demise. The endocannabinoid system has been crucially involved in the control of autoimmune demyelination and cannabinoid-based therapies exhibit therapeutic potential, but also limitations, in MS patients. In this context, growing evidence suggests that targeting the hydrolysis of the main endocannabinoid 2-arachidonoylglycerol (2-AG) may offer a more favorable benefit-to-risk balance in MS than existing cannabinoid medicines.

Current Status of Radiotherapy for the Management of Regional Nodes in Breast Cancer.

Worldwide, breast cancer is the most common invasive cancer in women. Breast cancer constitutes about 23% of invasive cancers in women. The management of breast cancer depends on various factors, including the cancer stage and patient age.

Blockade of monoacylglycerol lipase inhibits oligodendrocyte excitotoxicity and prevents demyelination in vivo.

The endocannabinoids 2-araquidonoylglycerol (2-AG) and anandamide (AEA) are bioactive lipids crucially involved in the regulation of brain function in basal and pathological conditions. Blockade of endocannabinoid metabolism has emerged as a promising therapeutic strategy for inflammatory diseases of the central nervous system, including myelin disorders such as multiple sclerosis. Nevertheless, the biological actions of endocannabinoid degradation inhibitors in oligodendrocytes and white matter tracts are still ill defined.

The aim of this work is to present the research line on quality of life that has been carried out since 1992 in the Oncology Departments of the Hospital de Navarra. These departments actively collaborate with the European Organisation of Research and Treatment of Cancer - EORTC - Quality of Life Group in creating questionnaires and also in other projects of this group.

[Clinical impact of image guided radiotherapy].

Image guided radiotherapy (IGR) is a concept that encompasses the most modern way of administering radiotherapy treatment. The aim is to maximise the dose deposited in the target volume, minimising the dose in healthy organs. This would not be possible without the continuous development of technology and software, above all in the following areas: deformable image registration, replanning new treatments, real time image and calculation of accumulated dose.

[The clinical application of intensity-modulated radiation therapy].

Intensity-modulated radiation therapy (IMRT) represents one of the greatest technical innovations in modern radiotherapy. Its capacity of achieving treatments with the dose conforming largely to the irradiated area makes it possible to treat volumes close to organs at risk with great safety These characteristics make it an ideal technique for studies, whether for reducing toxicity in organs at risk, or for intensifying dosages to improve the control of the disease. The first part of the article considers what is understood by IMRT and its peculiar dosimetric characteristics, as well the types of IMRT; the second part deals with the clinical evidence in some localisations such as tumours of the head and neck, prostate and breast.
