L-tryptophan is an essential amino acid that needs to be supplemented through protein-rich diet and it helps in growth and nitrogen balance in the humans.The aim of this studyis to evaluate the effect of the Trivedi Effect®-Consciousness Energy Healing Treatment on the L-tryptophan in terms of its physicochemical and thermal properties by usingmodern analytical techniques. The method involved dividing the testsample into two parts and providing the Consciousness Energy Healing Treatmentto one part (named as Biofield Energy Treated sample), remotely by a renowned Biofield Energy Healer, Dahryn Trivedi; while the other part didn’t receive any treatment called a control sample. The particle size values of the treated sample was increased by 4.77% (d10), 6.37% (d50), 6.72% (d90), and 6.49% {D(4,3)}; thus, the specific surface area was increased by 4.35% comparedto the control sample. The PXRD peak intensitiesand crystallite sizes of the treated sample were significantly altered ranging from -82.69% to 30.54% and -17.15% to 179.73%, respectively, in comparison to the control sample. The total weight loss of the treated sample was significantly reduced by 11.60% during the heating process that resulted in a significant increase in the residual amount of the sample by 1093.33% as compared to the control sample. The melting temperature and the latent heat of fusion of the treated sample was significantly increased by 1.12% and 6.79%, respectively, compared to the untreated sample. Hence, the L-tryptophan might forma new polymorph after the Trivedi Effect®-Consciousness Energy Healing Treatment that may possess better solubility and bioavailability profile along with improved thermal stability compared with the untreated sample. Thus, the Trivedi Effect®-Consciousness Energy Healing Treatment could be considered as a novel approach for designing the formulations with improved drug profile and efficacy. The treated L-tryptophan would be more useful for the treatment of mental health disorders, premenstrual dysphoric disorder (PMDD), attention deficit-hyperactivity disorder (ADHD), obsessive-compulsive disorder, depression, and bipolar disorder, etc.

Polylactic-co-glycolic acid (PLGA) is a biodegradable copolymer. It has many applications in the pharmaceuticals and biomedical industries, but its degradation and stability is a major concern. The objective of this study was to evaluate the influence of the Trivedi Effect® on the physicochemical and thermal properties of PLGA using modern analytical techniques. The PLGA sample was divided into control and Biofield Energy Treated parts. The control sample did not obtain the Biofield Energy Treatment, whereas the treated PLGA was received the Trivedi Effect®-Consciousness Energy Healing Treatment remotely by a renowned Biofield Energy Healer, Alice Branton. The particle size values of the treated PLGA were increased by 8.97%(d10), 8.79%(d50), 4.72%(d90), and 6.61%{D(4,3)}; thus, the surface area of treated PLGA was significantly decreased by 6.84% compared with the control sample. The latent heat of evaporation and fusion of the treated PLGA were significantly increased by 29.60% and 230.93%, respectively compared with the control sample. The residue amount was significantly increased by 21.99% in the treated PLGA compared to the control sample. The maximum thermal degradation temperature of the treated PLGA was increased by 2.30% compared with the control sample. It was concluded that the Trivedi Effect®-Consciousness Energy Healing Treatment might have generated a new form of PLGA which may show better powder flow ability, thermal stability, and minimize the hydrolysis of the ester linkages of PLGA. This improved quality of PLGA would be a better choice for the pharmaceutical formulations (i.e., the drug like simvastatin, amoxicillin, and minocycline loaded PLGA nanoparticles) and manufacturing of biomedical devices, i.e., grafts, sutures, implants, surgical sealant films, prosthetic devices, etc., in the industry using it as a raw material.

A fast, simple, solvent less and inexpensive sample preparation method based on Head space solid-phase micro extraction (HS-SPME) coupled to gas chromatography-electron-capture detector (GC-ECD) is proposed for the determination of mix pesticide residues from vegetable samples. Polydimethylsiloxane (PDMS, 100 μm) fiber was used in this study. The mix pesticides (24 nos.) including organochlorines (15), organophosphates (06) and synthetic pyrethriods (03) were analysed in the vegetable samples (Cabbage, Tomato, Cauliflower, Chilli, Okra, Brinjal, Bottle gourd, Cucumber, Beetroot, Spinach, and Radish) collected from in and around of Lucknow city, India. Present study revealed the presence of HCH, DDT, methylparathion, malathion, chlorpyrifos, monocrotophos, endosulfan, cypermethrin, fenvalerate pesticides. Pesticides residue levels were compared with MRL fixed by Prevention of Food Adulteration Act (PFA), Govt. of India 1954. The method detection limits were in a linearity range of 0.003 - 0.024 mg/kg. A recovery percent varies from 86.1 to 96.4% with relative standard deviation (RSD) of 14%. The outcomes of the present study point towards the crucial need of implementing strict government’s rules related to food safety in order to put check on these kinds of health hazardous food contamination.

Formulation of Generalized Electron Balance (GEB) for redox systems according to Approach II to GEB does not require the prior knowledge of oxidation numbers of all elements in components forming a system, and in the species of the system thus formed. This formulation is involved with linear combination of charge and elemental and/or core balances related to the system in question. The skillful choice of multipliers for the balances on the step of purposeful formulation of this linear combination allows for to find important regularities for electrolytic systems of different degree of complexity. These multipliers are related to the oxidation numbers of the elements; this regularity is important in the context of the fact that the oxidation number is the contractual concept. This property is valid for redox and non-redox systems. In this context, oxidation number is perceived as the derivative/redundant concept. The paper indicates the close relationships between different rules of conservation and indicates huge possibilities inherent in the generalized approach to electrolytic systems (GATES), and GATES/GEB in particular.

Chromatography is a tool to measure molecular interactions, and computational chemistry is a tool to explain molecular interactions. Therefore, reversed-phase liquid chromatography of acidic drugs using a pentyl- and an octyl-bonded silica gels was quantitatively analyzed in silico. A model pentyl- and an octyl-bonded silica gel and a methanol phases were constructed for docking with acidic drugs. Molecular interaction energy values based on van der Waals energy were obtained after docking an acidic drug into the model pentyl- or octyl-phases. Solvent effects, hydrogen bonding, and electrostatic energy values were obtained after docking an acidic drug onto the model methanol phase. Chromatographically measured log k values were correlated with the sum of van der Waals, hydrogen bonding, and electrostatic energy values. The correlation coefficient between the log k values measured using the pentyl-bonded silica gel phase and the molecular interaction energy values was 0.95 (n = 20); that between the log k values measured using the octyl-bonded silica gel and the molecular interaction energy values was 0.95 (n = 20).

Chemometric optimization and validation of a method based on High Performance Liquid Chromatography (HPLC) using core – shell particles for the determination of Vancomycin (VMC) in human plasma is reported. The combination of the efficiency of the core-shell particles and the benefits of the design of experiments allowed the successful determination of VCM, even in presence of several interferents. Selectivity, linearity, accuracy and precision were accomplished according to the European Medicines Agency (EMA) guideline, within the concentration range of 1.00 – 60.0 μg/mL of VCM. It is noteworthy that this method requires small amount of sample and solvents, and the sample treatment is simple and no time-consuming. Thus, this method becomes a simple and high-throughput alternative to therapeutic drug monitoring in treated patients, as well as an analytical procedure that conforms to the principles of the green chemistry.
