Differential Regulation Of tRNA1 Gly Genes In Bombyx Mori
(2012-03-30) -
Dissecting the C-DI-GMP Signaling Pathways : Tools and Tales
(2018-02-27)Evaluating aerodynamic noise from aircraft engines is a design stage process, so that it conform to regulations at airports. Aerodynamic noise is also a principal source of structural vibration and internal noise in ... -
Distinct extracellular signatures of active-dendritic chemical and electrical synapses differentially contribute to ripple-frequency oscillations
Extracellular field potentials across brain regions exhibit distinct signatures that depend on several region-specific attributes, including spatiotemporal patterns of afferent inputs, anatomical and physiological properties ... -
The Dynamics of Iron in Miniferritins : A Structure-Function Connection
(2017-11-23)The DNA binding proteins under starvation (Dps) from M. smegmatis are cage-like structures which internalize iron and bind DNA. They provide resistance to the cells from free radical damage, and physically protect the DNA ... -
Dynamics of Protein Kinases : Its Relationship to Functional Sites and States
(2018-05-22)A cell is a highly complex, ordered, and above all, a robust system. It copes with in-trennel and external uncertainties like heterogeneous stimuli, errors in processing and execution, and changes within and outside the ... -
Effect of sequence on DNA structure : Insights from molecular dyanmics studies
DNA is a flexible molecule, known to adopt a wide variety of structures ranging from right-handed A, B, C to left-handed Z DNA and higher-order structures like quadruplexes, depending on the sequence and environment. This ... -
Effect of Ultrasound on Neuronal Network Communication
(2018-05-22)Low intensity and low frequency ultrasound has been shown to modulate ion channel currents, membrane capacitive currents, and as a result, neuronal activity. Ultrasound has been used as a non-invasive way to modulate ... -
Effects of Cyclic Permutation, Glycan Removal and Aspartate Mutagenesis on Conformation of HIV-1 Envelope
It has been decades since Human Immunodeficiency Virus-1 (HIV-1) was discovered. The virus has created havoc worldwide. According to the UNAIDS 2014 Gap report, 35million people worldwide are infected with HIV-1 and yet ... -
Electrophysiological studies investigating drug effects on hHCN1 channels and Unravelling pore dynamics in Pannexin channels
Hyperpolarization-activated cyclic nucleotide-gated (HCN) ion channel stands out for its unique characteristics, including sensitivity to transmembrane voltage and cyclic nucleotides, as well as its non-selective passage ... -
Elucidating the Role of MsRbpA in Rifampicin Tolerance and Transcription Regulation of Mycobacterium Smegmatis
(2018-04-12)RNA polymerase binding protein A (RbpA) was first discovered as a RNA polymerase binding protein from Streptomyces. coelicolor. It was shown to cause rifampicin tolerance to RNA polymerase in vitro and leads to basal level ... -
Emergence and Homeostasis of Functional Maps in Hippocampal Neurons
(2017-11-23)Systematic investigations through several experimental techniques have revealed that hippocampal pyramidal neurons express voltage gated ion channels (VGICs) with well-defined gradients along their dendritic arbor. These ... -
Endotoxin Peptide/Protein Interactions: Thermodynamic And Kinetic Analysis
(Indian Institute of Science, 2006-05-15)Endotoxin or Lipopolysaccharide (LPS) is the invariant structural component of gram negative bacterial outer membranes and is the chief causative factor of Sepsis or endotoxic shock. Sepsis is a syndrome that has very high ... -
Energetics Of Protein-Carbohydrate Recognition
(Indian Institute of Science, 2006-04-28)The work embodied in this thesis pertains to an attempt to understand better, the molecular basis of protein-carbohydrate recognition. For this purpose a systematic study was undertaken, not only of the energetics of ... -
Engineering Reverse Turns: Implications in Conformation, Stability and Bioactivity of Peptides and Proteins
The work presented in this thesis provides an overview of the potential role of N-methylation in inducing reverse turns. Backbone N-methylation is one of the common modifications designed by nature and exploited by humans ... -
Enhancing Therapeutic Potential of Antimicrobial Peptides by Tuning Backbone Conformation
Full text embargo up to Dec 31, 2026 The work reported in this thesis involves tuning the backbone conformation of b-hairpin AMPs to reduce their cytotoxicity, which is determined in terms of reduced hemolytic activity, ... -
Epileptiform Activity Induced Alterations In Ca2+ Dynamics And Network Physiology Of Hippocampal Neurons - In Vitro Studies
(2010-07-15)Epilepsy is characterized by the hyperexcitability of individual neurons and hyper synchronization of groups of neurons (networks). The acquired changes that take place at molecular, cellular and network levels are important ... -
Estradiol Induced Changes In Neuronal Excitability And Neuron-Astrocyte Signaling In Mixed Hippocampal Cultures
(2010-03-02)One of the defining characteristics of the brain is its plasticity, which is the ability to alter and reorganize neuronal circuits. The brain is constantly being shaped and moulded by the external world through endogenous ... -
Expanding The Horizon Of Mycobacterial Stress Response : Discovery Of A Second (P)PPGPP Synthetase In Mycobacterium Smegmatis
