Characterization Of Physical, Thermal And Spectroscopic Properties Of Biofield Energy Treated P-Phenylenediamine And P-Toluidine, Mahendra Kumar Trivedi, Alice Branton, Dahryn Trivedi, Gopal Nayak, Ragini Singh, Snehasis Jana

Mahendra Kumar Trivedi

Aromatic amines and their derivatives are widely used in the production of dyes, cosmetics, medicines and polymers. However, they pose a threat to the environment due to their hazardous wastes as well as their carcinogenic properties. The objective of the study was to use an alternate strategy i.e. biofield energy treatment and analyse its impact on physicochemical properties of aromatic amine derivatives viz. p-phenylenediamine (PPD) and p-toluidine. For this study, both the samples were taken and divided into two parts. One part was considered as control and another part was subjected to Mr. Trivedi’s biofield treatment. After treatment, both samples …

1-Butaneboronic Acid Binding To Aeromonas Proteolytica Aminopeptidase:  A Case Of Arrested Development, Carin C. De Paola, Brian Bennett, Richard C. Holz, Dagmar Ringe, Gregory A. Petsko

Hydrolases containing two metal ions connected by a bridging ligand catalyze reactions important in carcinogensis, tissue repair, post-translational modification, control and regulation of biochemical pathways, and protein degradation. The aminopeptidase from Aeromonas proteolytica serves as a paradigm for the study of such bridged bimetallic proteases since its three-dimensional structure is known to very high resolution and its catalytic reaction is amenable to spectroscopic examination. Herein, we report the X-ray crystal structure at 1.9 Å resolution of AAP complexed with 1-butaneboronic acid (BuBA). This structure suggests that this complex represents a snapshot of the proteolytic reaction in an arrested form between …

The self-assembly of helical ribbons is examined in a variety of multicomponent enantiomerically pure systems that contain a bile salt or a nonionic detergent, a phosphatidylcholine or a fatty acid, and a steroid analog of cholesterol. In almost all systems, two different pitch types of helical ribbons are observed: high pitch, with a pitch angle of 54 ± 2°, and low pitch, with a pitch angle of 11 ± 2°. Although the majority of these helices are right-handed, a small proportion of left-handed helices is observed. Additionally, a third type of helical ribbon, with a pitch angle in the range …
