Circulating Cytokines Could Not Be Good Prognostic Biomarkers in a Mouse Model of Amyotrophic Lateral Sclerosis

Conclusions: We demonstrated in the SOD1G93A model of ALS that increased levels of several cytokines were associated with a shorter lifespan. However, their role as prognostic biomarkers is unclear as their expression was very variable depending on both the disease stage and the subject. Nevertheless, cytokines may be potential therapeutic targets. Introduction Amyotrophic Lateral Sclerosis (ALS) is one of the most common rare diseases of unknown origin that leads to progressive motor neuron degeneration and muscle denervation (1). In particular, it has been described that either distal axonopathy or neuromuscular junction damage precedes motor neuron loss (2). The known mutations that produce the typical adult ALS phenotype are, in order of frequency, the hexanucleotide repeat expansion in C9ORF72, mutations related to the copper/zinc superoxide-dismutase-1 gene (SOD1), Tar DNA-binding protein gene (TARDBP) and DNA/RNA-binding protein FUS (fused in sarcoma) (3, 4). Only 5–10% of ALS cases are familiar, whereas the rest of ALS cases are sporadic, most of them with unknown cause. The immune system has emerged as one of the key players linked to the development of neurodegeneration, such as in ALS (5–10). The immune system seems to have a dual role, polarizing its functional phenotype toward an inflammatory M1 phenotype or toward an anti-inflammatory M2 phenotype, depending on the particular neurodegenerative environment and by disease stage (7, 11). Although...

Publication date: Available online 21 January 2020Source: Advances in Space ResearchAuthor(s): Zhenghai Wang, Cong Zhou, Haoyang QinAbstractAdvanced space-borne thermal emission and reflection radiometer (ASTER) data were evaluated for the hydrothermal alteration mapping of the Nimu porphyry copper deposit, southern Tibet. According to the metallogenic model for porphyry copper, we chose hydrothermal alteration mineral association and then established a remote sensing model. Relative absorption-band depth (RBD) and simple band combination methods in visible near infrared (VNIR) and shortwave infrared (SWIR) bands were used...

AbstractOxidative stress is a pathophysiological hallmark of many CNS diseases, among multiple sclerosis (MS). Accordingly, boosting the astrocytic transcription factor nuclear factor E2-related factor 2 (Nrf2) system in an MS mouse model efficiently ameliorates oligodendrocyte loss, neuroinflammation and axonal damage. Moreover, Dimethylfumarate, an efficient activator of Nrf2, has recently been approved as therapeutic option in MS treatment. Here, we use the cuprizone mouse model of MS to induce oxidative stress, selective oligodendrocyte loss, microglia and astrocyte activation as well as axonal damage in both wild type...

AbstractGlioblastoma is a devastating tumor affecting the central nervous system with infiltrative capacity, high proliferation rate and chemoresistance. Therefore, it is urgent to find new therapeutic alternatives that improve this prognosis. Herein, we focused on tannic acid (TA) a polyphenol with antioxidant and antiproliferative activities. In this work, the antitumor and antioxidant effects of TA on rat (C6) glioblastoma cells and their cytotoxicity relative to primary astrocyte cultures were evaluated in vitro. Cells were exposed to TA of 6.25 to 75  μM for 24, 48 and/or 72 h. In addition, colony formati...

Abbott Laboratories has been wildly successful with its FreeStyle Libre continuous glucose monitor (CGM) since winning FDA approval in 2017, but it seems some investors and patients may be getting restless as the U.S. market waits for the second-generation of the blockbuster technology. We first noted some signs of impatience for Libre 2 in our coverage of Abbott's third-quarter earnings call in October. One reader commented on that article that "I don’t particularly care about investors becoming impatient, as a Freestyle Libre user I am growing impatie...

Authors: Crespo J, Carballo Álvarez F, Alberca de Las Parras F, Fernández Rodríguez CM, Vera Mendoza MI, Gómez M, Elola Somoza FJ Abstract The Spanish Society of Digestive Pathology has set a consensus document on the standards and recommendations for gastroenterology units (GU). These standards are considered as relevant in the organization and management of the unit to develop their activities with efficiency and quality. Four key groups of processes have been identified: a) care for the acutely ill adult patient; b) outpatient digestive endoscopy; c) in-hospital support to other servi...

Authors: Monsalve Alonso S, Miranda García P, Santander Vaquero C Abstract Cap-polyposis is a rare benign condition characterized by inflammatory colorectal polyps covered by a "cap" of fibrinopurulent exudate. Mucous diarrhea and rectal bleeding are frequent symtoms. It can be difficult to diagnose and it is necessary to make a differential diagnosis from other entities. Its pathogenesis is unknown and it has a variable clinical course. The optimal treatment has not been established. PMID: 31960689 [PubMed - as supplied by publisher]

We report the case of a 60-year-old male with a giant colorectal laterally spreading tumor at the recto-sigmoid junction. A single tunnel-assisted endoscopic submucosal dissection was performed that constructed a submucosal tunnel along the longitude axis of the tumor. An en bloc resection was achieved with no perforation or post-operative bleeding and a comparatively low procedure time. PMID: 31960681 [PubMed - as supplied by publisher]

Authors: Ruiz Rebollo ML, González Obeso E, Burgueño Gómez B, Santos Fernández J Abstract A 75-year-old male was referred due to dysphagia and iron-deficiency anemia. An upper endoscopy was performed which revealed a friable mass at 30 to 37 cm from the incisors, consistent with esophageal malignancy. However, the pathology only demonstrated granulation inflammatory tissue. An endoscopic ultrasound exam showed a 2-3 cm esophageal wall thickening with a 1.5 cm lymph node, which was staged as a T2-3 N1 esophageal tumor. A CT-scan also identified a 7.5 cm esophageal malignancy surrounded by...
