Glial Granules And Germline Proteins In The Drosophila Brain, Samuel J. Tindell Jan 2021

Glial Granules And Germline Proteins In The Drosophila Brain, Samuel J. Tindell

Murray State Theses and Dissertations

My overarching goal was to elucidate the role of Tudor (Tud) protein in the Drosophila brain. Tud is an evolutionarily conserved molecular scaffold, containing 11 Tud domains which bind to symmetrically dimethylated arginine (sDMA) residues in a variety of proteins. Tud is an essential component of embryonic ribonucleoprotein complexes (RNPs) called germ granules that contain RNAs and proteins crucial to the differentiation and maintenance of germ cells, the specialized class of stem cells that ultimately give rise to the next generation of organism. In the absence of Tud, there is a complete abolishment of germ cells highlighting its important role …

The Case For Decriminalisation Of Abortion, Jonathan Herring Jan 2021

The Case For Decriminalisation Of Abortion, Jonathan Herring

National Law School of India Review

This article makes the case for decriminalising abortion. It argues that abortion should be treated in the same way as other medical treatments, and only be a criminal offence if undertaken without the consent of the patient, or in a grossly inappropriate way. The article summarises the standard arguments made for decriminalising abortion: that the criminalisation restricts access to safe abortion and undermines women’s autonomy rights. The article also offers some further arguments in favour of decriminalisation from an ethic of care perspective. These are that abortion is a public good, in promoting caring relationships; that abortion protects rights of …

Identification Of Loci Influencing Teosinte Crossing Barrier 1 (Tcb1) Efficacy In Maize By Quantitative Trait Loci (Qtl) Mapping And Genome-Wide Association Study (Gwas), Namrata Maharjan

Electronic Theses and Dissertations

Pollen cross-contamination has been a major problem for maize breeders. Various mechanical methods applied to avoid the contaminations are ineffective. The genetic factors related to maize fertilization can be used to develop an effective method to prevent pollen contamination. Pollen rejection ability controlled by Teosinte crossing barrier 1 (Tcb1) is such a genetic system. Silks possessing dominant Tcb1-s reject pollen possessing the recessive allele (tcb1). Successful fertilization occurs when Tcb1-s pollen falls upon tcb1 silks. The efficacy of dominant Tcb1-s was, however, reduced when repeatedly backcross with maize inbred lines, which suggests that there are modifiers to Tcb1-s. To find …

Electrical Sensing In Non-Excitable Cells To Promote Galvanotaxis And Tissue Survival, Anyesha Sarkar

Electronic Theses and Dissertations

Weak DC fields have been shown to induce polarity, cell migration and cell proliferation in 2D cultures in vitro. To understand the mechanism by which non-excitable cells sense such weak EFs, we have investigated the mechanism of cathode-directed water flow (electro-osmosis) in the boundary layer of cells by reducing it with neutral, viscous polymers. Our results indicate that low molecular weight polymers decrease cathodal migration and promote anodal migration in a concentration dependent manner. High molecular weight polymers do not affect directionality and can be explained using porosity and hydraulic permeability between the polymers. These results provide the first evidence …
