Mechanisms and roles of the RNA-based gene silencing

Electronic Journal of Biotechnology , 2004,
Abstract: rna silencing is a remarkable type of gene regulation. this process has been found to occur in many different organisms such as plants (co-suppression), fungi (quelling), and animals (rna interference; rnai). double-stranded rna (dsrna) is a potent trigger in rna silencing mechanisms operating in a wide range of organisms. this mechanism recognizes dsrna and processes them into small 21-25nt rnas (smrnas). small rnas can guide post-transcriptional degradation of complementary messenger rnas and in plants, transcriptional gene silencing is occurred by methylation of homologous dna sequences. in plants, it serves as an antiviral defense, and many plant viruses encode suppressors of silencing such as helper component-proteinase of potyviruses (hc-pro) and the p25 protein encoded by potato virus x (pvx). hc-pro acts by preventing accumulation of smrnas that provide specificity determinant for homologous rna degradation, but p25 viral protein acts by targeting the mobile silencing signal. the encouraging view is that rna silencing is part of a sophisticated network of interconnected pathways for cellular defense and development and that it may become a powerful tool to manipulate gene expression experimentally.

Abstract: Bile salt (BS) and proteose peptone (PP) are important biomacromolecules being produced inside the human body. The objective of this study was to investigate the influence of biofield treatment on physicochemical properties of BS and PP. The study was performed in two groups (control and treated). The control group remained as untreated, and biofield treatment was given to treated group. The control and treated BS and PP samples were characterized by particle size analyzer (PSA), Brunauer-Emmett-Teller (BET) analysis, differential scanning calorimetry (DSC), x-ray diffraction (XRD), and thermogravimetric analysis (TGA). PSA results showed increase in particle size (d50 and d99) of both treated BS and PP as compared to control. Surface area analysis showed minimal decrease by 1.59%, in surface area of treated BS as compared to control. However, the treated PP showed increase (8%) in surface area as compared to control. DSC characterization showed increase in melting temperature of treated BS as compared to control. Whereas, DSC thermogram of treated PP showed decrease in melting temperature with respect to control. Moreover, the DSC of control and treated PP showed presence of exothermic peaks which were possibly due to protein aggregation. The treated PP showed higher exothermic transition temperature as compared to control. XRD analysis revealed slight reduction in crystalline nature of BS as compared to control. On the other hand, XRD data of control and treated PP showed an amorphous nature. TGA analysis of treated BS showed maximum thermal decomposition temperature at 22°C which was higher as compared to control sample (106°C). This could be due to biofield treatment which may enhance the thermal stability of treated BS with respect to control. However, the TGA thermogram of treated PP showed decrease in maximum thermal stability as compared to control. The overall results showed that biofield treatment has significantly altered the physical and thermal properties of BS and PP.

Molecular Pharmaceutics & Organic Process Research , 2015, DOI: 10.4172/2329-9053.1000127
Abstract: Thymol and menthol are naturally occurring plant derived compounds, which have excellent pharmaceutical and antimicrobial applications. The aim of this work was to evaluate the impact of biofield energy on physical and structural characteristics of thymol and menthol. The control and biofield treated compounds (thymol and menthol) were characterized by X-ray diffraction (XRD), Differential Scanning Calorimetry (DSC), Thermogravimetric analysis (TGA), and Fourier Transform Infrared Spectroscopy (FT-IR). XRD study revealed increase in intensity of the XRD peaks of treated thymol, which was correlated to high crystallinity of the treated sample. The treated thymol showed significant increase in crystallite size by 50.01% as compared to control. However, the treated menthol did not show any significant change in crystallite size as compared to control. DSC of treated menthol showed minimal increase in melting temperature (45oC) as compared to control (44oC). The enthalpy (ΔH) of both the treated compounds (thymol and menthol) was decreased as compared to control samples which could be due the high energy state of the powders. TGA analysis showed that thermal stability of treated thymol was increased as compared to control; though no change in thermal stability was noticed in treated menthol. FT-IR spectrum of treated thymol showed increase in wave number of –OH stretching vibration peak (14 cm-1) as compared to control. Whereas, the FT-IR spectrum of treated menthol showed appearance of new stretching vibration peaks in the region of 3200-3600 cm-1 which may be attributed to the presence of hydrogen bonding in the sample as compared to control. Overall, the result showed that biofield treatment has substantially changed the structural and physical properties of thymol and menthol.

Marmara Pharmaceutical Journal , 2017, DOI: 10.12991/marupj.300796
Abstract: Sodium selenate is an important inorganic compound but lacks reliable and accurate physico-chemical and spectral characterization information. The study was carried out for the in-depth physicochemical, thermal, and spectroscopic characterization of sodium selenate using various analytical techniques. The powder X-ray diffraction spectroscopy analysis showed well-defined and sharp peaks indicated sodium selenate is crystalline in nature. The crystallite size was found to be in the range of 28.75 to 49.97 nm. The average particle size was found to be of 3.93 (d10), 14.44 (d50), and 40.648 (d90) μm with an average surface area of 0.676 m2/g. The differential scanning calorimetry showed the endothermic inflation at 588.81 °C with the latent heat of fusion 103 J/g. The thermogravimetric analysis revealed two steps of the thermal degradation process. Similarly, the differential thermogravimetric analysis exhibited the major peaks in the thermogram and disclosed Tmax at 852.65 °C. The UV-visible spectrum showed maximum absorbance at 205.1 nm (λmax). The Fourier transform infrared spectrum showed a peak at 888 cm-1 due to the Se-O stretching. This information would be very much useful in the field of nutraceuticals/ pharmaceuticals and other industries using sodium selenate as an ingredient.

Abstract: Herbomineral formulations have been accepted world-wide due to its significant therapeutic outcomes. The study aimed to evaluate the immunomodulatory potential of novel herbomineral formulation (TEBEH) on Sprague Dawley rats using cyclophosphamide-induced immunosuppression. Major immune related parameters were monitored such haemagglutination assay, delayed type hypersensitivity reaction, cellular immune response (CD4+ and CD8+), IgG and IgM, hematological analysis, antioxidant profile, and estimation of major lipid biomarkers. The study results suggest herbomineral formulation significantly (p ≤ 0.05) improved the concentration of primary and secondary titre by 41.18 and 68%. However, the rat paw edema at 24 h showed increased edema by 77.78% (p ≤ 0.01). Herbomineral formulation exhibited increase in the CD4+ and CD8+ counts in animals by 28.03 and 60.70%, respectively. In addition, the concentrations of IgM and IgG were improved by 14.29 and 8.26% respectively. Besides, other supportive parameter such as hematology and antioxidant profile was significantly (p ≤ 0.001) improved, while free radical, lipid peroxidation was decreased. Moreover, the major lipid biomarkers were improved such as decreased triglycerides, LDL and VLDL by 15.88, 3.65, and 16.01%, respectively. Overall, the promising results of this study indicated that the herbomineral formulation, TEBEH can be employed to improve the cellular and humoral immunity along with improved hematological, antioxidant, and lipid profile.

Abstract: Vitamins, minerals, and nanocurcumin play a substantial role in various nutraceutical/pharmaceutical formulations that are widely used in therapeutics, cosmetics, and dietary supplements. The current study aimed to investigate the comparative in vitro immunomodulatory effect of a novel nanocurcumin-based formulation with curcumin in LPS-induced cytokine expression, NK cells’ activity, and phagocytosis. The proinflammatory cytokines (TNF-α, IL-1β, and MIP-1α) and NK cells’ activity were measured in cell supernatants using ELISA assay; however, phagocytosis activity was performed using colorimetric analysis. The chemical characterization of novel nanocurcumin-based formulation using LC–MS (R t 19.02 min) and mass spectra analysis (m/z 369.04) confirmed the presence of the curcumin in highest peak concentration. MTT assay in three tested cell-lines showed that the formulation was found non-toxic at all the tested concentrations. The expression of TNF-α, IL-1β, and MIP-1α in splenocytes was significantly (p ≤ 0.001) inhibited. Besides, the NK cells’ activity and phagocytosis (macrophage) were increased significantly (p ≤ 0.001). Overall, the promising results of this study indicated the significant immunomodulatory effect of nanocurcumin-based formulation compared to the curcumin, which could be used against various inflammatory disorders such as allergy, asthma, autoimmune diseases, coeliac disease, inflammatory bowel disease, etc.

Abstract: 2,6-Dichlorophenol (2,6-DCP) is a compound used for the synthesis of chemicals and pharmaceutical agents. The present work is intended to evaluate the impact of Mr. Trivedi’s biofield energy treatment on physical, thermal and spectral properties of the 2,6-DCP. The control and treated 2,6-DCP were characterized by various analytical techniques such as X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR) spectroscopy, and ultra violet-visible spectroscopy (UV-vis) analysis. The XRD results showed the increase in crystallite size of treated sample by 28.94% as compared to the control sample. However, the intensity of the XRD peaks of treated 2,6-DCP were diminished as compared to the control sample. The DTA analysis showed a slight increase in melting temperature of the treated sample. Although, the latent heat of fusion of the treated 2,6-DCP was changed substantially by 28% with respect to the control sample. The maximum thermal decomposition temperature (Tmax) of the treated 2,6-DCP was decreased slightly in comparison with the control. The FT-IR analysis showed a shift in C=C stretching peak from 1464→1473 cm-1 in the treated sample as compared to the control sample. However, the UV-vis analysis showed no changes in absorption peaks of treated 2,6-DCP with respect to the control sample. Overall, the result showed a significant effect of biofield energy treatment on the physical, thermal and spectral properties of 2,6-DCP. It is assumed that increase in crystallite size and melting temperature of the biofield energy treated 2,6-DCP could alleviate its reaction rate that might be a good prospect for the synthesis of pharmaceutical compounds.

Abstract: Objective: Chloramphenicol and tetracycline are broad-spectrum antibiotics and widely used against variety of microbial infections. Nowadays, several microbes have acquired resistance to chloramphenicol and tetracycline. The present study was aimed to evaluate the impact of biofield treatment for spectroscopic characterization of chloramphenicol and tetracycline using FT-IR and UV-Vis spectroscopy. Methods:The study was performed in two groups (control and treatment) of each antibiotic. The control groups remained as untreated, and biofield treatment was given to treatment groups. Results: FT-IR spectrum of treated chloramphenicol exhibited the decrease in wavenumber of NO2 from 1521 cm-1 to 1512 cm-1 and increase in wavenumber of C=O from 1681 cm-1 to 1694 cm-1 in acylamino group. It may be due to increase of conjugation effect in NO2 group, and increased force constant of C=O bond. As a result, stability of both NO2 and C=O groups might be increased in treated sample as compared to control. FT-IR spectrum of treated tetracycline showed the downstream shifting of aromatic C-H stretching from 3085-3024 cm-1 to 3064-3003 cm-1 and C=C stretching from 1648-1582 cm-1 to 1622-1569 cm-1 and up shifting of C-N stretching from 965 cm-1 to 995 cm-1. It may be due to enhanced conjugation effect in tetracycline, and increased force constant of C-N (CH3) bond of tetracycline as compared to control. The results indicated the enhanced stability of treated tetracycline as compared to control. UV-Vis spectra of biofield treated chloramphenicol and tetracycline showed the similar lambda max (λmax) to their respective control. It revealed that the chromophore groups of both antibiotics remained same as control after the biofield treatment. Conclusion: Based on FT-IR spectroscopic data, it is speculated that due to increase in bond strength and conjugation effect after biofield treatment, the chemical stability of both the drugs might be increased as compared to control.

Abstract: P-tert-Butyphenol (PTBP) is a phenolic monomer used in the synthesis of numerous industrially useful chemicals. The current research work aimed to evaluate the effect of the biofield energy treatment on the isotopic abundance ratios of PM 1/PM and PM 2/PM in PTBP using gas chromatography - mass spectrometry (GC-MS). The sample, PTBP was distributed into two parts - one part was designated as control PTBP and another part was considered as biofield energy treated PTBP. The biofield energy treatment was achieved through unique biofield energy transmission process by Mr. Trivedi (also known as The Trivedi Effect). T1, T2, T3, and T4 were indicated to the different time interval analysis of the biofield treated PTBP. The GC-MS spectra of the both control and biofield treated PTBP showed the presence of molecular ion peak [M ] at m/z 150 (calculated 150.10 for C10H14O) along with eight major fragmented peaks at m/z 135, 107, 95, 91, 77, 65, 41, and 39, which might be due to C10H15 , C7H7O or C8H11 , C6H7O , C7H7 , C6H5 , C5H5 , C3H5 , and C3H3? ? ions, respectively. The relative intensities of the parent molecule and other fragmented ions of the biofield treated PTBP were altered as compared to the control PTBP. The percentage in the isotopic abundance ratio of PM 1/PM was enhanced in the biofield treated PTBP at T2, T3 and T4 by 1.60%, 3.57%, and 120.13%, respectively while it was decreased by 4.14% in the treated sample at T1 with respect to the control PTBP. Consequently, the isotopic abundance ratio of PM 2/PM was increased in the biofield treated PTBP at T1, T3, and T4 by 1.28%, 2.56%, and 123.08%, respectively with respect to the control sample. On the other hand, it was reduced in the biofield treated sample at T2 by 1.28% as compared to the control PTBP. Concisely, 13C, 2H, and 17O contributions from (C10H14O) to m/z 151 and 18O contribution from (C10H14O) to m/z 152 in the biofield treated PTBP were changed with respect to the control sample and was found to have time dependent effect. The biofield energy treated PTBP might display isotope effects such as different physicochemical and thermal properties, rate of the reaction, selectivity and binding energy due to the changed isotopic abundance ratio as compared to the control sample. Biofield treated PTBP could be valuable for the designing new chemicals and pharmaceuticals through using its kinetic isotope effects.

Abstract: Methyl-2-napthylether (nerolin) is an organic compound and has the applications in pharmaceutical, and perfume industry. The stable isotope ratio analysis is increasing importance in various field of scientific research. The objective of the current study was to evaluate the effect of the biofield energy treatment on the isotopic abundance ratios of PM 1/PM (2H/1/sup>H or 13C/12C or 17O/16O) and PM 2/PM (18O/16O) in nerolin using the gas chromatography-mass spectrometry (GC-MS). The compound nerolin was divided into two parts - one part was control sample (untreated), and another part was considered as biofield energy treated sample which was received the biofield energy treatment through the unique biofield energy transmission process by Mr. Mahendra Kumar Trivedi (also known as The Trivedi Effect ). The biofield energy treated nerolin was analyzed at different time intervals and were represented as T1, T2, T3, and T4 in order to understand the effect of the biofield energy treatment on isotopic abundance ratio with respect to the time. From the GC-MS spectral analysis, the presence of the molecular ion peak C11H10O (m/z 158) along with major fragmented peaks C10H7O- (m/z 143), C10H8 (m/z 128), C9H7 (m/z 115), C7H5 (m/z 89), C5H3 (m/z 63), C4H3 (m/z 51), and C3H3 (m/z 39) were observed in both control and biofield treated samples. Only, the relative peak intensities of the fragmented ions in the biofield treated nerolin was notably changed as compared to the control sample with respect to the time. The isotopic abundance ratio analysis of nerolin using GC-MS revealed that the isotopic abundance ratio of PM 1/PM in the biofield energy treated nerolin at T1, T2, T3, and T4 was increased by 2.38, 138.10, 13.10, and 32.14%, as compared to the control sample. Likewise, the isotopic abundance ratio of PM 2/PM at T1, T2, T3, and T4 was increased by 2.38, 138.10, 13.10, and 32.14%, respectively in the biofield treated nerolin as compared to the control sample. Overall, the isotopic abundance ratios of PM 1/PM (2H/1H or 13C/12C or 17O/16O) and PM 2/PM (18O/16O) were significantly increased in the biofield energy treated sample as compared to the control sample with respect to the time. It is concluded that Mr. Trivedi’s biofield energy treatment has the significant impact on alteration in isotopic abundance of nerolin as compared to the control sample. The biofield treated nerolin might display different altered physicochemical properties and rate of reaction and could be an important intermediate for the production of pharmaceuticals, chemicals, and perfumes in the industry.
