Some aspects of the metabolism of mandelic acid by pseudomonas convexa, Ph.D. Thesis
The metabolism of mandelic acid (phenylglycolic acid) has been studied in detail in several bacteria, and it has been shown that the side chain of mandelic acid is first degraded, resulting in the formation of benzoic acid, ... -
Spatial and Coevolutionary Dynamics of Cooperation
Cooperation is ubiquitous across taxa in the animal kingdom. For example, microbes cooperate in producing antibiotic-resistant biofilms, mammals and birds collectively mob predators, and humans cooperate in utilization of ... -
Spatial and temporal patterns of vegetation- climate interactions
In this thesis, I tried to understand the patterns and processes of vegetation trends at different spatial scales and resolution. The spatial variability in vegetation trends was related to inter and intra-annual changes ... -
Spatial Variation In Interactions Of The Semi-Myrmecophyte Humboldtia Brunonis (Fabaceae) With Ants And Other Invertebrates
(2010-06-01)Despite a long history of investigations on protective ant-plant interactions, since the late 19century (Thomas Belt 1874), a comprehensive quantitative understanding of the adaptations that facilitate these associations ... -
Spatio-Temporal Control Of Drosophila Indirect Flight Muscle Development And Maintenance By The Transcription Factor Erect Wing
(2016-04-27)Muscle development involves concerted action of a repertoire of mechanisms governing myoblast proliferation, migration, fusion and differentiation. Subsequently, there are cellular events administrating proper muscle ... -
Spatio-temporal Regulation of GPCR mediated MAPK Transactivation in Living Cells
Signal transduction is a mode of cellular communication essential for an organism’s sustenance and survival. Cell communication in higher organisms is largely executed by two classes of cell surface receptors i.e. G-protein ... -
Species Ranges, Richness and Replacement of Trees in the Evergreen Forests of the Western Ghats
(2018-05-14)It has been more than two centuries since the latitudinal pattern of increase in taxonomic richness from poles to equator was first documented. After two centuries of research, and with more than two dozen hypotheses ... -
Specificity and mechanism of action of ribonuclease Ti-A computer modelling study
Enzymes recognize their substrates with very high specificity and bring about a large increase in the rates of reactions. A knowledge of the specificity and mechanism of action of enzyme-catalyzed reactions at the molecular ... -
Spectroscopic studies on two biological amphiphiles: melittin and Birlirubin.
This thesis describes spectroscopic studies on two interesting biological amphiphiles, melittin and bilirubin. The former is a 26?residue polypeptide which comprises ~50% of the dry venom of honeybees. Melittin is cytotoxic ... -

Spermatogenomics : Correlating Testicular Gene Expression to Human Male Infertility
(2018-06-13)Spermatogenesis is a complex and coordinated process of formation of sperms from the precursor spermatogonia, occurring inside the unique environment existing in the seminiferous epithelium. This process of development, ... -
Spike-Timing-Dependent Plasticity at Excitatory Synapses on the Rat Subicular Pyramidal Neurons
(2018-05-08)The subiculum is a structure that forms a bridge between the hippocampus and the entorhinal cortex (EC) in the brain, and plays a major role in the memory consolidation process. It consists of different types of pyramidal ... -
SRF regulates the generation of neuroprotective astrocytes in the brain
In response to injuries, infections or in neurodegenerative disorders, astrocytes get activated to become reactive. This phenomenon is called astrogliosis and is marked by a spectrum of changes which encompasses structural, ... -
Starvation Response In Mycobacterium Smegmatis : A Tale Of Two Proteins
(2010-10-19)The Dps (DNA-Binding Protein from Starved Cells) proteins are a class of stress-specific proteins with a major role in protecting DNA during the stationary phase of bacterial growth, through direct physical binding as well ... -
Stereochemical analysis on protein structures - Lessons for design, engineering and prediction
The results of the present analysis demonstrate that local van der Waals contacts are overwhelmingly dominant in determining the backbone conformations of amino acid residues in globular protein structures. The number of ... -
Stereochemical studies on peptide and protein structures: Implications for validation, flexibility, and dynamics
Accuracy of 3-D structures of proteins is crucial, both in terms of its agreement with the experimental data used to determine the structure and stereochemistry, especially when they are utilized for applications like drug ... -
Stimulus statistics and HCN current mediated resonance sets the scale of input-output mapping in Stellate cells of the Medial Entorhinal Cortex
The functional significance of the computations performed by Stellate cells of the Medial Entorhinal Cortex, proven time and again, makes them insightful, yet intriguing. The gradients of the intrinsic properties of these ... -
Stop codon readthrough in MTCH2 mRNA and its role in mitochondrial physiology
Stop codon readthrough is the process in which translation continues beyond a stop codon till a downstream, in-frame stop codon generating a polypeptide with a C-terminal extension. MTCH2 was selected as a potential ...
