Editorial: Biotechnology of plant secondary metabolites: Phytochemical biopharming as a sustainable contribution to a high-tech bioeconomy
No full textPlant cell and tissue culture has made a great contribution to the advance of knowledge in plant biotechnology (Altman 2019). Today thousands of biotech companies distributed around the world produce millions of micropropagated plants, contributing to certified seed programs of a wide spectrum of commercial varieties for the agricultural, forestry and food industries. However, the biotechnological production of secondary metabolites has lagged behind the previously mentioned advances in translational plant biotechnology. So much so that with current developments in cell biology, cell, tissue and plant cultures are considered tools that should promote the use of plant biodiversity as an essential biotechnological resource focused on the production of natural phytocompounds for a wide spectrum of applications (Pasdaran and Hamedi 2017; Ochatt et al., 2022
Metodo di bioreattore ad immersione temporanea e relativo prodotto - ITRE2012A000080
No full textUn metodo di bioreattore ad immersione temporanea ed un prodotto ottenuto con tale metodo, il metodo comprendendo le fasi di: a. collocare una o più piante in grado di eseguire la fotosintesi all'interno di un contenitore; b. introdurre nel contenitore un terreno liquido, in modo da immergere le piante e lasciarle in immersione per un lasso di tempo in modo da moltiplicare le piante e produrre biomassa vegetale; c. rimuovere il terreno liquido dal contenitore e lasciare le piante in una atmosfera di aria con aggiunta di anidride carbonica per un altro lasso di tempo; d. ripetere le fasi b. e c. in modo alternato per un determinato periodo di tempo complessivo, sottoponendo le piante ad una radiazione fotosinteticamente attiva
Biotechnological Approaches to Produce Phenylpropanoids in Controlled Conditions
No full text.Plants synthesize an array of natural products based on the phenylpropane skeleton which have multiple functions, highlighting their antioxidant properties adding values to the nutraceutical, pharmaceutical and cosmetology industries, between others. This paper take attention to four biotechnology advances towards make efficient the production of these secondary metabolites. I.- Design and development of efficient methodologies for plant cultures in Temporary Immersion Bioreactors (TIBs); II.- Management of the in vitro photosynthesis to reach photomixotrophic plant cultures; III.- Elicitation of the phenylpropanoids pathway during in vitro cultures; IV.- Polyploidy induction as a biotechnological tool for plant genetic improvement. The model species have been commercial genotypes of blueberries (Vaccinium corymbosum), raspberries (Rubus idaeus) and maqui (Aristotelia chilensis) and, the phenylpropanoids metabolites have been determined indistinctively in biomass and culture medium from both in vitro and ex vitro plantlets. Perspectives in the industrialization of the phenylpropanoids production as a circular bioeconomic process are discusse
METODO DI BIOREATTORE AD IMMERSIONE TEMPORANEA E RELATIVO PRODOTTO
No full textA temporary immersion bioreactor method and a product obtained therefrom, the method comprising steps of: a. inserting one or more plants (200) capable of enacting photosynthesis into a container (110); b. inserting a liquid medium (205) into the container (110), such as to immerse the plants (200), leaving the plants (200) immersed for a period of time such as to multiply the plants and grow vegetable biomass; c. removing the liquid medium (205) from the container (110) and leaving the plants (200) in an air atmosphere with added carbon dioxide for a further period of time; d. repeating steps b. and c. in alternation for a predefined total period of time, exposing the plants (200) to a photosynthetically-active radiation

A simulation study of new security schemes in mobile Ad-hoc NETworks
No full textThis work provides both a new global authentication system for Mobile Ad-hoc NETworks and a study of its simulation with NS-2. The proposed scheme is constructed in a self-organizing manner, which implies the fulfillment of most requirements for this type of networks, such as adaptation to the changing topology of the network, public availability of broadcast communications and strength of access control.+7

A General Purpouse Control System
No full textIndustrial control applications are developed as ad hoc solutions. These solutions require specific programming and installation, and very often it takes large economic investments. We have developed a system that makes a special effort trying to offer versatility and a solution to a widespread of industrial installations. Our system understands an industrial plant as a compound of sensors, actuators and processes. The user will define its own processes, sensors and actuators. It will also be in his hand the design of the plants visualization diagram. In order to achieve this generalness it is of essence to offer a user interface as friendly as possible. Via a very intuitive user interface the implemented functionalities are far more powerful because the user understand them and makes use of them.11210
Cerebral atrophy in mild cognitive impairment and Alzheimer disease: rates and acceleration.
Get PDFOBJECTIVE: To quantify the regional and global cerebral atrophy rates and assess acceleration rates in healthy controls, subjects with mild cognitive impairment (MCI), and subjects with mild Alzheimer disease (AD). METHODS: Using 0-, 6-, 12-, 18-, 24-, and 36-month MRI scans of controls and subjects with MCI and AD from the Alzheimer's Disease Neuroimaging Initiative (ADNI) database, we calculated volume change of whole brain, hippocampus, and ventricles between all pairs of scans using the boundary shift integral. RESULTS: We found no evidence of acceleration in whole-brain atrophy rates in any group. There was evidence that hippocampal atrophy rates in MCI subjects accelerate by 0.22%/year2 on average (p = 0.037). There was evidence of acceleration in rates of ventricular enlargement in subjects with MCI (p = 0.001) and AD (p < 0.001), with rates estimated to increase by 0.27 mL/year2 (95% confidence interval 0.12, 0.43) and 0.88 mL/year2 (95% confidence interval 0.47, 1.29), respectively. A post hoc analysis suggested that the acceleration of hippocampal loss in MCI subjects was mainly driven by the MCI subjects that were observed to progress to clinical AD within 3 years of baseline, with this group showing hippocampal atrophy rate acceleration of 0.50%/year2 (p = 0.003). CONCLUSIONS: The small acceleration rates suggest a long period of transition to the pathologic losses seen in clinical AD. The acceleration in hippocampal atrophy rates in MCI subjects in the ADNI seems to be driven by those MCI subjects who concurrently progressed to a clinical diagnosis of AD
