A team of researchers at the University of California at San Diego have created a soft robotic lens that responds to eye movements.

Numéricable has selected the Calix E7-2 Ethernet Service Access Platform and gigabit passive optical network technology to upgrade its service delivery platform in Belgium and Luxembourg. Calix, along with optical specialist Arcadiz Telecom, will work closely to roll out Numéricable’s new high-speed broadband networks to deliver business services across the region. The new platform will enable Numéricable’s customers to take advantage of advanced voice, video, and data services at symmetrical speeds ranging from 30 megabits per second (30 Mbps) up to 1 gigabit per second (1 Gbps).

Numéricable serves over 150,000 customers in Brussels with triple-play services for residential subscribers. Owned by Coditel and with a close relationship to the French Numéricable organization, with whom it shares a range of resources, Numéricable Belgium is a long-established operator with a highly dispersed coax cable network. The company has traditionally delivered triple-play residential services over its hybrid fiber coax infrastructure, but in recent years has moved increasingly towards using its fiber to connect businesses and has developed a number of specific niche markets. The company is now looking at ways to maximize the potential of its fiber infrastructure in Belgium and Luxembourg and deliver revenue-generating advanced services to its business customers.

The companies are part of a shift toward deeper integration between online and offline operations.

NAD+ is a central metabolite participating in core metabolic redox reactions. The prokaryotic NAD synthetase enzyme NadE catalyzes the last step of NAD+ biosynthesis, converting nicotinic acid adenine dinucleotide (NaAD) to NAD+. Some members of the NadE family use l-glutamine as a nitrogen donor and are named NadEGln. Previous gene neighborhood analysis has indicated that the bacterial nadE gene is frequently clustered with the gene encoding the regulatory signal transduction protein PII, suggesting a functional relationship between these proteins in response to the nutritional status and the carbon/nitrogen ratio of the bacterial cell. Here, using affinity chromatography, bioinformatics analyses, NAD synthetase activity, and biolayer interferometry assays, we show that PII and NadEGln physically interact in vitro, that this complex relieves NadEGln negative feedback inhibition by NAD+. This mechanism is conserved in distantly related bacteria. Of note, the PII protein allosteric effector and cellular nitrogen level indicator 2-oxoglutarate (2-OG) inhibited the formation of the PII-NadEGln complex within a physiological range. These results indicate an interplay between the levels of ATP, ADP, 2-OG, PII-sensed glutamine, and NAD+, representing a metabolic hub that may balance the levels of core nitrogen and carbon metabolites. Our findings support the notion that PII proteins act as a dissociable regulatory subunit of NadEGln, thereby enabling the control of NAD+ biosynthesis according to the nutritional status of the bacterial cell.

The prostate-specific membrane antigen (PSMA) is an excellent target for theranostic applications in prostate cancer (PCa). However, PSMA-targeted radioligand therapy can cause undesirable effects due to high accumulation of PSMA radiotracers in salivary glands and kidneys. This study assessed orally administered monosodium glutamate (MSG) as a potential means of reducing kidney and salivary gland radiation exposure using a PSMA targeting radiotracer. Methods: This prospective, double-blind, placebo-controlled study enrolled 10 biochemically recurrent PCa patients. Each subject served as his own control. [¹⁸F]DCFPyl PET/CT imaging sessions were performed 3 – 7 days apart, following oral administration of either 12.7 g of MSG or placebo. Data from the two sets of images were analyzed by placing regions of interest on lacrimal, parotid and submandibular glands, left ventricle, liver, spleen, kidneys, bowel, urinary bladder, gluteus muscle and malignant lesions. The results from MSG and placebo scans were compared by paired analysis of the ROI data. Results: A total of 142 pathological lesions along with normal tissues were analyzed. As hypothesized a priori, there was a significant decrease in maximal standardized uptake values corrected for lean body mass (SULmax) on images obtained following MSG administration in the parotids (24 ± 14%, P = 0.001), submandibular glands (35 ± 11%, P<0.001) and kidneys (23 ± 26%, P = 0.014). Significant decreases were also observed in lacrimal glands (49 ± 13%, P<0.001), liver (15 ± 6%, P<0.001), spleen (28 ± 13%, P = 0.001) and bowel (44 ± 13%, P<0.001). Mildly lower blood pool SULmean was observed after MSG administration (decrease of 11 ± 13%, P = 0.021). However, significantly lower radiotracer uptake in terms of SULmean, SULpeak, and SULmax was observed in malignant lesions on scans performed after MSG administration compared to the placebo studies (SULmax median decrease 33%, range -1 to 75%, P<0.001). No significant adverse events occurred and vital signs were stable following placebo or MSG administration. Conclusion: Orally administered MSG significantly decreased salivary gland, kidney and other normal organ PSMA radiotracer uptake in human subjects, using [¹⁸F]DCFPyL as an exemplar. However, MSG caused a corresponding reduction in tumor uptake, which may limit the benefits of this approach for diagnostic and therapeutic applications.

The human MASTL (Microtubule-associated serine/threonine kinase-like) gene encodes an essential protein in the cell cycle. MASTL is a key factor preventing early dephosphorylation of M-phase targets of Cdk1/CycB. Little is known about the mechanism of MASTL activation and regulation. MASTL contains a non-conserved insertion of 550 residues within its activation loop, splitting the kinase domain, and making it unique. Here, we show that this non-conserved middle region (NCMR) of the protein is crucial for target specificity and activity. We performed a phosphoproteomic assay with different MASTL constructs identifying key phosphorylation sites for its activation and determining whether they arise from autophosphorylation or exogenous kinases, thus generating an activation model. Hydrogen/deuterium exchange data complements this analysis revealing that the C-lobe in full-length MASTL forms a stable structure, whereas the N-lobe is dynamic and the NCMR and C-tail contain few localized regions with higher-order structure. Our results indicate that truncated versions of MASTL conserving a cryptic C-Lobe in the NCMR, display catalytic activity and different targets, thus establishing a possible link with truncated mutations observed in cancer-related databases.

For all the cynicism it has evoked, the United States’ Iraq Study Group report might still lead to a regional diplomatic process, which could ease Iran and the US into negotiations. A grand bargain is very unlikely, but with Washington at the table, there might be enough advantage for both sides in a gradual process to halt the current slide towards a deeper confrontation.

OBJECTIVE

Topical oxygen has been used for the treatment of chronic wounds for more than 50 years. Its effectiveness remains disputed due to the limited number of robust high-quality investigations. The aim of this study was to assess the efficacy of multimodality cyclical pressure Topical Wound Oxygen (TWO2) home care therapy in healing refractory diabetic foot ulcers (DFUs) that had failed to heal with standard of care (SOC) alone.

OBJECTIVE

To assess the efficacy and safety of a 1:1 fixed-ratio combination of insulin glargine and lixisenatide (iGlarLixi) versus lixisenatide (Lixi) in insulin-naive Japanese patients with type 2 diabetes mellitus (T2DM) inadequately controlled on oral antidiabetic drugs (OADs).

OBJECTIVE

The role of U300 glargine insulin for the inpatient management of type 2 diabetes (T2D) has not been determined. We compared the safety and efficacy of glargine U300 versus glargine U100 in noncritically ill patients with T2D.

Rock 'n' roll icon Little Richard died Saturday at age 87, his family said.

Fresh, bright and delicious.

This deliciously warming Ayurvedic gluten-free breakfast idea came from my good friend Brenda when she owned Mondo Organics in Brisbane. I've tweaked it a little to suit what was in my pantry today. The perfect brekky after Sunday morning yoga and a great way to start your surfing day. Rolled rice is available at most good food stores and organic outlets. Best to use fresh turmeric for its antioxidant properties and up to you whether you want yoghurt too. I prefer mine with a squeeze of lime. Om Shanti.

Growing numbers of African and Asian migrants are moving through Latin America, many hoping to reach the United States or Canada after expensive, arduous, and often dangerous journeys that can take months or even years. As more extracontinental migrants transit through South and Central America, Colombia, Panama, and Costa Rica have developed the most comprehensive policies to manage these flows, sometimes working in coordination with the U.S. government.

About 14,000 more students in the state are enrolled in special education, after the state lifted what it called a "benchmark" enrollment figure of 8.5 percent.

The U.S. Department of Education said Texas must stop using a guideline for special education enrollment that may have led to thousands of children being denied services they were qualified to receive.

Officials want to hear from parents, students and educators in the wake of a newspaper series that said Texas is suppressing special education enrollment.

Jan. 6 is the last day to submit comments to the U.S. Department of Education about their experiences with Texas' special education identification processes.

The federal office of special education programs said the state failed to ensure that students were properly evaluated for special education, as required by the Individuals with Disabilities Education Act.

Wisconsin’s Palmyra-Eagle district has lost more than half its students in the last decade, sparking a fiscal crisis. A special board is deciding whether the district should be allowed to dissolve.

This researchprojectimplemented a randomizedcontrolledtrial ofthe SEAM program in Terms 3 and 4 ofthe 2016 school year. The purpose of the study was to determine the effects of the SEAM program. The study enrolled 448 treatment group students who were referred to SATOs for potential SEAM intervention, and 448 matched control group students who were not referred to SATOs. Approximately one-third of treatment group students received a compulsory conference notice, approximately one-third of treatment students' families signed an attendance plan, about 20% had a compulsory conference take place, and payment was suspended for approximately 5% of treatment students. No significant differences following any of these interventions were observed between treatment and control students.

"A light-hearted take on the Australian toilet paper shortage. With a lot of worry and fear in the world today (2020), it is important to be informed and make good decisions based on the facts at hand. Panic buying caused supply shortages for some products. In Australia, one of the bizarre products to fall to panic buying was toilet roll. This little book, produced as a light-hearted response, offers a reminder that there is always an alternative. Contained in this book are sixteen "sheets". It may be single ply, but we are sure you will agree the 70lb paper has plenty of bulk" -- from the introduction.
