Potassium-Selective Channelrhodopsins, Elena G Govorunova, Oleg A Sineshchekov, John L Spudich

Faculty, Staff and Student Publications

Since their discovery 21 years ago, channelrhodopsins have come of age and have become indispensable tools for optogenetic control of excitable cells such as neurons and myocytes. Potential therapeutic utility of channelrhodopsins has been proven by partial vision restoration in a human patient. Previously known channelrhodopsins are either proton channels, non-selective cation channels almost equally permeable to Na+ and K+ besides protons, or anion channels. Two years ago, we discovered a group of channelrhodopsins that exhibit over an order of magnitude higher selectivity for K+ than for Na+. These proteins, known as “kalium channelrhodopsins” or KCRs, lack the canonical tetrameric …

A Model Of Evangelism For A Bilingual Worship Community, Dorkham Donovan See

Doctoral Dissertations and Projects

The purpose of this DMIN action research project is to develop a model of evangelism for the Lahu-English bilingual worship community at Calvary Evangelical Free Church in Rochester, Minnesota. This study claims that the Lahu-English bilingual worship community has not emphasized evangelism—to share the gospel beyond this group—due to the decline of Christian influence in general and the cultural and language barriers that first and second- generation Lahu Christians encounter. Most ethnic worship communities tend to congregate and remain in their sphere of social and worship gatherings as a haven and belonging. While this is not intrinsically wrong, it ignores …

The Role Of Military Chaplains And Effective Spiritual Care For Strengthening Military Marriages During Deployments, Carl Michael Johnson

Doctoral Dissertations and Projects

Military chaplains provide spiritual support and counseling to the military populations alongside conducting religious services. As a military process, chaplaincy operates as a liaison between military personnel, mental health professionals, and clinical marriage counselors. In this context, the military population is extensive and consists of military personnel, military chaplains, and their civilian families. It must be acknowledged that various service-motivated challenges confront these individuals. For instance, military marriages are threatened by lengthy deployment and family separations. Therefore, it is significant to contextualize military marriages’ coping, survival, and strengthening as most contemporary researchers have focused on this subject. Most studies have …

Pcl And Dmso2 Composites For Bio-Scaffold Materials, Jae-Won Jang, Kyung-Eun Min, Cheolhee Kim, Chien Wern, Sung Yi

Mechanical and Materials Engineering Faculty Publications and Presentations

Polycaprolactone (PCL) has been one of the most popular biomaterials in tissue engineering due to its relatively low melting temperature, excellent thermal stability, and cost-effectiveness. However, its low cell attraction, low elastic modulus, and long-term degradation time have limited its application in a wide range of scaffold studies. Dimethyl sulfone (DMSO2) is a stable and non-hazardous organosulfur compound with low viscosity and high surface tension. PCL and DMSO2 composites may overcome the limitations of PCL as a biomaterial and tailor the properties of biocomposites. In this study, PCL and DMSO2 composites were investigated as a new bio-scaffold material to increase …

Fuzzy Kc Clustering Imputation For Missing Not At Random Data, Markku A. Malmi Jr.

USF Tampa Graduate Theses and Dissertations

The Influence Of Child Maltreatment In The Manifestation Of Anxiety And Depressive Symptoms At The Age 18, Maria J. Velasquez

LSU Master's Theses

Child maltreatment affects thousands of children and adolescents every year. This phenomenon is multidimensional, meaning there are different subtypes (i.e., physical abuse, sexual abuse, emotional abuse, and neglect) known to predict various mental health issues, including depression and anxiety. While previous research has investigated mental health outcomes in maltreated youth, results may vary based on the dimensions of abuse considered. This study aims to expand on previous literature to examine how a history of child maltreatment subtypes influences the manifestation of anxiety and depressive symptoms in youth at age 18. The current study uses secondary data analysis of the Longitudinal …

Conjugation's Toolkit: The Roles Of Nonstructural Proteins In Bacterial Sex, Matthew B Cooke, Christophe Herman

Faculty, Staff and Students Publications

Bacterial conjugation, a form of horizontal gene transfer, relies on a type 4 secretion system (T4SS) and a set of nonstructural genes that are closely linked. These nonstructural genes aid in the mobile lifestyle of conjugative elements but are not part of the T4SS apparatus for conjugative transfer, such as the membrane pore and relaxosome, or the plasmid maintenance and replication machineries. While these nonstructural genes are not essential for conjugation, they assist in core conjugative functions and mitigate the cellular burden on the host. This review compiles and categorizes known functions of nonstructural genes by the stage of conjugation …
