Mahalanobis distance correlation: A novel approach for quantitating changes in multidimensional NMR spectra in biological applications.

J Magn Reson

April 2022

UM-DAE Centre for Excellence in Basic Sciences, University of Mumbai, Kalina, Mumbai, Maharashtra 400098, India; Department of Biosciences and Bioengineering, IIT Bombay, Powai, Mumbai, Maharashtra 400076, India. Electronic address:

We present here a novel protocol for quantitating changes in the NMR spectra, which is based on Mahalanobis statistics. In a two dimensional NMR spectrum, the various peaks are taken to represent a distribution, and the two chemical shifts along the orthogonal axes and the peak intensities constitute three observables. All these observables vary in a correlated manner.

Identifying type of sugar adulterants in honey: Combined application of NMR spectroscopy and supervised machine learning classification.

Curr Res Food Sci

January 2022

Export Inspection Agency- Chennai (Head Office), 6th Floor CMDA Tower-II, No: 1 Gandhi Irwin Road, Egmore, Chennai, 600008, India.

Nuclear magnetic resonance (NMR) is a powerful analytical tool which can be used for authenticating honey, at chemical constituent levels by enabling identification and quantification of the spectral patterns. However, it is still challenging, as it may be a person-centric analysis or a time-consuming process to analyze many honey samples in a limited time. Hence, automating the NMR spectral analysis of honey with the supervised machine learning models accelerates the analysis process and especially food chemistry researcher or food industry with non-NMR experts would benefit immensely from such advancements.

Biotic and abiotic stress factors drastically limit plant growth and development as well as alter the physiological, biochemical and cellular processes. This negatively impacts plant productivity, ultimately leading to agricultural and economical loss. Plant defense mechanisms elicited in response to these stressors are crucially regulated by the intricate crosstalk between defense hormones such as jasmonic acid (JA), salicylic acid and ethylene.

Programmed cell death (PCD) is a genetically controlled process for the selective removal of damaged cells. Though understanding about plant PCD has improved over years, the mechanisms are yet to be fully deciphered. Among the several molecular players of PCD in plants, B cell lymphoma 2 (Bcl-2)-associated athanogene (BAG) family of co-chaperones are evolutionary conserved and regulate cell death, growth and development.

Targeting disorders in unstructured and structured proteins in various diseases.

UM-DAE Centre for Excellence in Basic Sciences, University of Mumbai, Vidhyanagri Campus, Kalina, Mumbai 400098, India. Electronic address:

Intrinsically disordered proteins (IDPs) and intrinsically disordered protein regions (IDPRs) are proteins and protein segments that usually do not acquire well-defined folded structures even under physiological conditions. They are abundantly present and challenge the "one sequence-one structure-one function" theory due to a lack of stable secondary and/or tertiary structure. Due to conformational flexibility, IDPs/IDPRs can bind with multiple interacting partners with high-specificity and low-affinity and perform essential biological functions associated with signalling, recognition and regulation.

New air and moisture stable di--butyltin complexes derived from 2-mercaptopyridine (HSpy), [BuSn(Spy)], [BuSn(Cl)(Spy)] and 4,6-dimethyl-2-mercaptopyrimidine (HSpymMe) [BuSn(Cl)(SpymMe)], have been prepared and utilized as single-source molecular precursors for the preparation of orthorhombic SnS nanoplatelets by a hot injection method and thin films by aerosol assisted chemical vapour deposition (AACVD). The complexes were characterized by NMR (H, C, Sn) and elemental analysis and their structures were unambiguously established by the single crystal X-ray diffraction technique. Thermolysis of these complexes in oleylamine (OAm) produced SnS nanoplatelets.

Apoptosis is a naturally occurring process during the growth and development of multicellular organisms and is increasingly active during times of cellular stress such as in response to intracellular DNA damage when removal of the host cell is paramount to prevent cancer. Unfortunately, once formed, cancer cells become impervious to apoptosis, creating a desperate need to identify an approach to induce apoptosis in these cells. An attractive option is to focus efforts on developing and locating compounds which activate apoptosis using natural compounds.

Homi Bhabha National Institute, Anushaktinagar, Mumbai, 400 094, India; Radiation and Photochemistry Division, Bhabha Atomic Research Centre, Mumbai, 400085, India. Electronic address:

The aim of present study was to investigate the anticancer mechanisms of 3,3'-diselenodipropionic acid (DSePA), a redox-active organodiselenide in human lung cancer cells. DSePA elicited a significant concentration and time-dependent cytotoxicity in human lung cancer cell line A549 than in normal WI38 cells. The cytotoxic effect of DSePA was preceded by an acute decrease in the level of basal reactive oxygen species (ROS) and a concurrent increase in levels of reducing equivalents (like GSH/GSSG and NADH/NAD) within cells.

The change in the color of chromophore upon being embedded in a biological tissue is known as metachromasia. Basic Orange 21 (BO21) is a cationic polymethine dye that has been implied as a supravital dye, which produces metachromasia in leukocytes. An improved differential counting of leukocytes has been achieved in the clinical setup based on characteristic metachromatic expressions of BO21 for different types of leukocytes.

Histone modifications and DNA methylation together govern promoter availability, thereby influencing gene expression. This study queries the unicellular chlorophyte, using a three step "epigenetic assay" design to phenotypically track the variegation of a randomly integrated Paromomycin resistance transgene(s) (). Based on its position of integration, the gene expression hinged on two epigenetic hallmarks: the spreading of heterochromatin, and the transmissible memory of epigenetic states across generations.

We report a study of chromophore-catalyst assemblies composed of light harvesting hexabenzocoronene (HBC) chromophores axially coordinated to two cobaloxime complexes. The chromophore-catalyst assemblies were prepared using bottom-up synthetic methodology and characterized using solid-state NMR, IR, and x-ray absorption spectroscopy. Detailed steady-state and time-resolved laser spectroscopy was utilized to identify the photophysical properties of the assemblies, coupled with time-dependent DFT calculations to characterize the relevant excited states.
