Effect Of Vitamin C And Probiotics On Broilers Performance And Claudin-2 (Cldn-2) Expression Under Heat Stress [Research Note], Mohammad Chamani, Mohammad Chamani, Farhad Foroudi, Ali Asghar Sadeghi, Mehdi Aminafshar Jun 2023

Effect Of Vitamin C And Probiotics On Broilers Performance And Claudin-2 (Cldn-2) Expression Under Heat Stress [Research Note], Mohammad Chamani, Mohammad Chamani, Farhad Foroudi, Ali Asghar Sadeghi, Mehdi Aminafshar

The Philippine Agricultural Scientist

This study was conducted to investigate the effect of vitamin C and probiotic which consists of five species of beneficial bacteria and two species of fungi on performance, blood parameters, and intestinal CLDN-2 gene expression of broilers during heat stress (HS). A total of 400 broilers were randomly divided into five groups, each of which received a different treatment. The first group was considered a negative control and did not experience any HS (C-); the second group was considered a positive control (C+) and was exposed to HS; the third group received only vitamin C (250 …


Cluster Homolog Of Immunoglobulin-Like Receptor Genes In Chicken Immune Responses, Brandi A. Sparling Jan 2023

Cluster Homolog Of Immunoglobulin-Like Receptor Genes In Chicken Immune Responses, Brandi A. Sparling

Graduate Theses, Dissertations, and Problem Reports

This dissertation explores the identity and role of immunoglobulin-like (Ig-like) receptors in chickens, with focus on their implications in disease and disease progression. These receptors, wisely expressed across immune cells, interact with the major histocompatibility complex (MHC) class I molecules to modulate immune responses in mammals. Due to the insufficient representation of chicken Ig-like receptors in online databases, this study systematically annotates the chicken Cluster Homolog of Immunoglobulin-like Receptors (CHIR) genes using advanced bioinformatic techniques, aligning with the release of the 7th edition of the chicken genome assembly that comprises builds for a broiler and layer chicken. The analysis identifies …


Comparison Of The Humoral Immune Response Following Both Bacterial Challenge And Rnai Of Major Factors On Proliferation Of Bartonella Quintana In The Human Louse, Jake Zina Oct 2022

Comparison Of The Humoral Immune Response Following Both Bacterial Challenge And Rnai Of Major Factors On Proliferation Of Bartonella Quintana In The Human Louse, Jake Zina

Masters Theses

Human body lice, Pediculus humanus humanus, and head lice, Pediculus humanus capitis, have been hematophagous ectoparasites of humans for thousands of years. Despite being ecotypes, only body lice are known to transmit bacterial diseases to humans, and it appears that lower humoral and cellular immune responses allow body lice to possess a higher vector competence. We previously observed that the transcription level of the defensin 1 gene was up-regulated only in head lice following oral challenge of Bartonella quintana, a causative agent of trench fever, and also that body lice excreted more viable B. quintana in their …

Investigating The Driving Mechanisms Behind Differences In Bleaching And Disease Susceptibility Between Two Scleractinian Corals, Pseudodiploria Strigosa And Diploria Labyrinthiformis, Zoe A. Pratte Jun 2015

Investigating The Driving Mechanisms Behind Differences In Bleaching And Disease Susceptibility Between Two Scleractinian Corals, Pseudodiploria Strigosa And Diploria Labyrinthiformis, Zoe A. Pratte

FIU Electronic Theses and Dissertations

Disease and bleaching are two conditions which commonly lead to coral death. Among coral species, susceptibility to disease and bleaching is variable, and Pseudodiploria strigosa tends to be diseased more than Diploria labyrinthiformis, while D. labyrinthiformis bleaches more readily. The focus of this dissertation was to investigate and compare multiple components of these two coral species, and identify how they may relate to disease and bleaching resistance. Compenetnts examined included the surface mucopolysacharide layer (SML) thickness, gene expression, microbial associates, and a white plague aquarium study. The SML thickness decresased with increasing temperature regardless of coral species, indicating that SML …


Parasite Infection Mediates Trait Tradeoffs In Fundulus Heteroclitus, Sarah Dunn May 2015

Parasite Infection Mediates Trait Tradeoffs In Fundulus Heteroclitus, Sarah Dunn

Honors College Theses

To be successful, an animal must eat, grow, and reproduce. With limited resources, there are tradeoffs between these critical life history parameters but the direction of the tradeoffs is largely unknown in a changing environment. To determine whether environmental context affects life-history tradeoffs, I surveyed and quantified investment into reproduction, growth, and a proxy for immunity (parasitism), in the mummichog, Fundulus heteroclitus, a common inhabitant of salt marshes in Georgia. Three salt marsh sites along coastal Georgia (Shellman Bluff, Skidaway Island, and Tybee Island) were selected using a proxy for anthropogenic disturbance (impervious surface), which also fell along a …

Investigating The Mechanism Of Nur77-Induced Apoptosis In T Cells, Heather E. Fogarty Jan 2012

Investigating The Mechanism Of Nur77-Induced Apoptosis In T Cells, Heather E. Fogarty

Masters Theses 1911 - February 2014

Nur77 is a member of the orphan nuclear receptor family, where it is known to play an important role in apoptosis in both negative selection in T cells and in cancer cell lines. In the development of T cells, it is critical for the immune system to discriminate self from non-self by eliminating auto-reactive cells. It was originally thought that Nur77 initiated apoptosis by activating downstream gene targets. However, it is now clear that Nur77 has its own distinct role outside of the nucleus and the precise mechanisms by which Nur77 induces apoptosis in T cells still needs to be …
