m R.N.A. Purifications Process: Affinity Chromato-Graphy, Magnetic Beads and Graphene Coated Large Scale Production and Toxicological Aspects


Aim of this work is to verify the state of the art related m R.N.A. purification process , the technology used as well as the materials employed. New methods vs classic methods: the use of affinity cromato-graphy or and high‐gradient magnetic separation (H.G.M.S.). In particular the use of magnetic beads since introduction of the graphene coated ones. Various producers provide many kind of magnetic beads with various grade of efficiency in separation. Becasue today there is a great debate around graphene derivates peresence (or not) in vials of m R.N.A. VACCINE it is relevant to better clarify the production process as well and the materials used.

During last periods in order to fight Covid-19 pandemia was introduced with emergency autorization a new class of vaccine: The m R.N.A. vaccine. This innovative biopharmaceutical products was developed starting form the research in the previous decade related oncologic vaccine research. It is interestig so verifying the manifacturing process used in example to purify this molecule from the impurities or other non useful component. The classic method used solvent , but in order to increase efficiency of the process was introduced purification trough chromatographic methods ( in example affinity cromato-graphy and high efficiency methods With high-gradient magnetic separation (H.G.M.S. ) and other )

 Lateral Rock Characteristic Evidence of Hydrocarbon Restoration from Post-Stack Impedance Inversion: A Case Study of ZED-field Offshore Niger Delta Lateral predictions of rock properties that are descriptive of a reservoir have been studied using a model-established seismic inversion approach that was used to convert input seismic data into an acoustic impedance structure to optimize hydrocarbon restoration in the field. This was actualized by integrating wireline logs and 3D post stack seismic data procured from ZED-Field offshore Niger Delta. The inversion system employed in this study comprises of forward modelling of reflection coefficients starting with a low-frequency impedance model induced from well logs and convolution of the reflection coefficients with the source wavelet extracted from the seismic input. P-impedance analysis at reservoir C5000 delineated from the control well gave a near perfect correlation of 0.998109 (≈ 99.8 %) between the original P-impedance log, in...

Prediction of Ionic Liquids Methane Hydrate Average Depression Temperature via COSMO-RS COSMO-RS is a tool used to pre-screen and pair ionic liquids for gas hydrate mitigation. However, the ionic liquids properties estimated from COSMO-RS lack direct connectivity to the determination of the safety margin (hydrate depression temperature) the inhibitor can alter on the hydrate phase boundary conditions. In this study, a parametric function that relates COSMO-RS estimated ionic liquid surface area and hydrogen bonding energies to the methane hydrate average depression temperature (∆T) have been presented. The statistical model in this study was developed using multiple linear regression techniques on about 90 data samples at 10 wt.% ionic liquids. The developed model in this work accurately predicts the methane hydrate average depression temperature with standard error of 3.14 and average deviation error of 0.92. Also, the ionic liquid surface area and hydrogen bonding energy contribute t...

 How to Treat Cancer Properly Cancer is one of the deadliest diseases in the world, chemotherapy is effective under some conditions, but has too heavy side effects, and it is not effective to a considerable proportion of cases while the side effects are often life-threatening, drugs (not unhealthy addictive drugs mentioned in reference four, the drug in reference four only mean those makes people addictive but does no good to health, destroying health quickly) are not always available to improve the condition. However, sport is a potential treatment that is effective to cancer before the cancer is disseminated, this gets little attention but is true both in theory and practice. The physical activities that have moderate intensity and duration should have devastating effects on cancer cells, they make the body hot and reduce the nutritional resources that cancer cells can get, also renew the proteins in the body and improve one’s mood, cancer cells are hard to live when one is activ...
