Plants have an enormous importance for life on earth but are often overlooked. This phenomenon called plant blindness is reinforced as students prefer to spend their recreation time with modern med...
Ancillary Services in the Energy Blockchain for Microgrids
2019
The energy blockchain is a distributed Internet protocol for energy transactions between nodes of a power system. Recent applications of the energy blockchain in microgrids only consider the energy transactions between peers without considering the technical issues that can arise, especially when the system is islanded. One contribution of the paper is, thus, to depict a comprehensive framework of the technical and economic management of microgrids in the blockchain era, considering, for the first time, the provision of ancillary services and, in particular, of the voltage regulation service. When more PV nodes are operating in the grid, large reactive power flows may appear in the branches…
Challenges and directions for Blockchain technology applied to Demand Response and Vehicle-to-Grid scenarios
2021
Abstract Nowadays, Blockchain is considered a consolidated technology supporting many different applications that integrate well with Artificial Intelligence and the Internet of Things, and supports the creation of Decentralized Autonomous Organizations. Within this wider framework, the energy blockchain applications are now deserving more and more attention, since blockchain architectures, on one hand, provide transparency and solve the information asymmetry problem, on the other, provide disintermediation. In this way, the dream of an energy market closer to end-users becomes a reality, although, still, the regulatory framework is not clear, especially for what concerns the tokenization o…
Basic knowledge of social hierarchies and physiological profile of reared sea bass Dicentrarchus labrax (L.).
2019
The effects of social hierarchies (dominant/subordinate individuals), such as aggressiveness, feeding order, and territoriality, are some of the characteristics used for describing fish behaviour. Social hierarchy patterns are still poorly understood in European-reared sea bass (Dicentrarchus labrax). In this work, we examine the social interactions among captive fish integrating behavioural and physiological profiles. Groups of three fish with EMG (electromyogram) radio transmitters were monitored for two weeks via video recording. Plasma levels of cortisol, glucose, lactate and lysozyme as well as haematological parameters such as haemoglobin, haematocrit and RBCC (red blood cell count) w…
Glucose regulation and grip strength in adults: Findings from the Helsinki Birth Cohort Study.
2021
Aim: this study aimed to assess the association between grip strength and glucose regulation in a cross-sectional setting.Methods: using data from the Helsinki Birth Cohort Study, 924 men and 953 women were studied at a mean age of 61.6 years. Grip strength was assessed in the dominant hand using a Newtest Grip Force dynamometer. A standard 2-h 75 g oral glucose tolerance test (OGTT) was used to define glucose regulation. The participants were classified into four groups: normoglycaemia, prediabetes (impaired fasting glucose or impaired glucose tolerance), newly diagnosed diabetes and previously known diabetes. The association between grip strength and glucose regulation was assessed using …
Dietary polyphenols and type 2 diabetes: Human Study and Clinical Trial
2018
IF 6.015 (2017); International audience; Significant evidence from epidemiological investigations showed that dietary polyphenols might manage and prevent type 2 diabetes (T2D). This review summarizes human studies and clinical trials of polyphenols as anti-diabetic agents. Polyphenols from coffee, guava tea, whortleberry, olive oil, propolis, chocolate, red wine, grape seed, and cocoa have been reported to show anti-diabetic effects in T2D patients through increasing glucose metabolism, improving vascular function as well as reducing insulin resistance and HbA1c level. However, individual flavonoid or isoflavonoid compounds appear to have no therapeutic effect on diabetes, based on the lim…
The changes of lipid metabolism in advanced renal cell carcinoma patients treated with everolimus: a new pharmacodynamic marker?
2015
Background: Everolimus is a mammalian target of rapamycin (mTOR) inhibitor approved for the treatment of metastatic renal cell carcinoma (mRCC). We aimed to assess the association between the baseline values and treatmentrelated modifications of total serum cholesterol (C), triglycerides (T), body mass index (BMI), fasting blood glucose level (FBG) and blood pressure (BP) levels and the outcome of patients treated with everolimus for mRCC. Methods: 177 patients were included in this retrospective analysis. Time to progression (TTP), clinical benefit (CB) and overall survival (OS) were evaluated. Results: Basal BMI was significantly higher in patients who experienced a CB (p=0,0145). C, T an…
The gut microbiota: An emerging risk factor for cardiovascular and cerebrovascular disease
2018
Commensal gut microbiota have recently been implicated in cardiovascular disease (CVD) and cerebrovascular disease. Atherosclerotic plaque formation depends on the colonization status of the host. In addition to host nutrition and the related microbiota-dependent metabolic changes, activation of innate immune pathways triggers the development of atherosclerosis and supports arterial thrombosis. Gnotobiotic mouse models have uncovered that activation of Toll-like receptor-2 by gut microbial ligands supports von Willebrand factor-integrin mediated platelet deposition to the site of vascular injury. Depending on nutritional factors, the microbiota-derived choline-metabolite trimethylamine N-ox…
A biostable, anti-fouling zwitterionic polyurethane-urea based on PDMS for use in blood-contacting medical devices.
2020
Polydimethylsiloxane (PDMS) is commonly used in medical devices because it is non-toxic and stable against oxidative stress. Relatively high blood platelet adhesion and the need for chemical crosslinking through curing, however, limit its utility. In this research, a biostable PDMS-based polyurethane-urea bearing zwitterion sulfobetaine (PDMS-SB-UU) was synthesized for potential use in the fabrication or coating of blood-contacting devices, such as a conduits, artificial lungs, and microfluidic devices. The chemical structure and physical properties of synthesized PDMS-SB-UU were confirmed by (1)H-nuclear magnetic resonance ((1)H-NMR), X-ray diffraction (XRD), and uniaxial stress-strain cur…
The evolving role of platelets in inflammation.
2003
Platelets are small in size and simple in structure. Nevertheless, these anucleate cytoplasts utilize complex molecular systems to regulate a variety of biological functions. Here we review evolutionary paths, traditional roles, and previously unrecognized biological capacities of platelets that interface thrombosis with inflammation and potentially identify new roles in inflammatory diseases.
