Acoustic Signals, Mate Choice And Mate Sampling Strategies in a Field Cricket
(2017-10-05)Acoustic communication in orthopterans and anurans provides a suitable model system for studying the evolutionary mechanisms of sexual selection mainly because males use acoustic signals to attract females over long distances ... -
Activation Of Glycoprotein Hormone Receptors : Role Of Different Receptor Domains In Hormone Binding And Signaling
(2014-07-16)The glycoprotein hormones, Luteinizing Hormone (LH), human Chorionic Gonadotropin (hCG), Follicle Stimulating Hormone (FSH) and Thyroid Stimulating Hormone (TSH) are heterodimeric proteins with an identical α-subunit ... -
Activin and TGF-β signaling: Differential role of a Serine/Threonine phosphate in the regulation of SMAD2 activity
Activins are the most prominent members of the Activin/Inhibin branch of the TGF-β superfamily. Similar to TGF-β, they play an essential role in regulating multiple physiological processes such as development, reproductive ... -
Adjunct Therapy with Curcumin for the Treatment of Malaria : Studies in a Murine Model
(2018-05-16)Malaria accounts for 198 million cases worldwide; with a high mortality rate. 584000 deaths were reported in 2013. Malaria is a re-emerging disease globally due to drug resistance, parasite recrudescence and non-availability ... -
Ageing associated altered host response to bacterial infection
Chapters in which I have elucidated and elaborately described how senescence alters the cellular response to infection, here I demonstrate how senescence in multiple tissues simultaneously contribute to pathogen spread and ... -
Altering DNA topology in mycobacteria: impact of perturbation of DNA gyrase on physiology and gene expression
In the current dissertation, efforts have been made to probe the in vivo role of DNA gyrase to determine its importance in the growth, physiology and gene expression in mycobacteria. In this dissertation, the role of DNA ... -
Alternate Fates of tRNAs in Initiation and Elongation
Protein synthesis in all organisms utilizes a special tRNA called the initiator tRNA. Initiator tRNAs take part in the initiation step of protein synthesis by their direct binding to the P‐site of the ribosome. The other ... -
Amylases From A Thermophilic Fungus Thermomyces Lanuginosus Iisc 91 :Their Purification And Properties
(Indian Institute of Science, 2005-04-06)A knowledge of molecular properties and structure of heat-stable enzymes is important for the understanding of basic principles governing thermo stability of proteins and evolution of life at high temperatures. Information ... -
Analysis Of Protein Evolution And Its Implications In Remote Homology Detection And Function Recognition
(2009-07-22)One of the major outcomes of a genome sequencing project is the availability of amino acid sequences of all the proteins encoded in the genome of the organism concerned. However, most commonly, for a substantial proportion ... -
Anti-thrombotic Secondary Metabolites from Endophytic Fungi of Datura Metel and Cassia Fistula
Blood coagulation is a process that occurs normally in an animal during bleeding, to prevent the loss of blood from the body and is assisted by two key players -blood platelets and coagulation factors particularly thrombin. ... -
Antigenic Determinants Of Chicken Riboflavin Carrier Protein: Structural And Functional Aspects
(Indian Institute of Science, 2005-09-01)Investigations detailed in this thesis constitute a part of the continuing programme of research undertaken in our laboratory on the riboflavin carrier protein (RCP) with particular reference to identification and synthesis ... -
Antimicrobial Peptides And Salmonella Pathogenesis
(2011-02-07)Chapter-I Introduction The bacteria known as Salmonellae are gram-negative, rod-shaped intracellular pathogenic bacilli that belong to the family Enterobacteriacea and causes typhoid fever. Enteric fever or typhoid ... -
Ants, Figs, Fig Wasps : The Chemical Ecology Of A Multitrophic System
(2013-04-01)Plant–animal interaction systems are complex food webs where the members—plants, pollinators, herbivores, parasites and predators of the pollinators/herbivores—interact with each other in ways which maximize their own ...
