The Cardinality Of The Permutations On A Set With N Non-Fixed Points, Jukkrid Nuntasri Jan 2022

The Cardinality Of The Permutations On A Set With N Non-Fixed Points, Jukkrid Nuntasri

Chulalongkorn University Theses and Dissertations (Chula ETD)

In this thesis, we study relationships between |Sn(A)| and |seqn1-1(A)| as well as |seqn(A)| for infinite sets A, where Sn(A) is the set of permutations of A with n non-fixed points and seqn(A) and seqn1-1(A) are the set of sequences and the set of one-to-one sequences of elements of A with length n, respectively, where n is a natural number greater than 1. With the Axiom of Choice (AC), |Sn(A)|, |seqn1-1(A)|, and |seqn(A)| are equal for all infinite sets A. Among our results, we show, in the Zermelo-Fraenkel set theory (ZF), that |Sn(A)|<=|seqn1-1(A)| for any infinite set A under some weak form of AC and the assumption cannot be removed. In the other direction, we show that |seqn1-1(A)|<=|Sn+1(A)| for any infinite set A and the subscript n+1 cannot be reduced to n. Moreover, we also show that "|Sn(A)|<=|Sn+1(A)| for any infinite set A" is not provable in ZF.

The Effect Of Histone Methylation In Trained Innate Immunity Of Cord Blood Monocytes In Newborn Infants Of Chronic Hbv-Infected Mothers, Pennapa Plypongsa

Chulalongkorn University Theses and Dissertations (Chula ETD)

Newborns contract Hepatitis B virus (HBV) through exposure in utero from mothers who are infected with HBV. In newborn infant from chronic HBV-infected mothers, the immune system displays innate immune cell maturation and enhances immune response upon restimulation with unrelated pathogens such as bacteria. This pattern is called “trained immunity” or “innate immune memory”. Trained immunity is regulated by epigenetic programming, especially histone modification. To date, there is not report on the epigenetics to regulate trained immunity in HBV. Therefore, this study investigated the cytokines levels and expression levels of histone modification enzyme genes in HBV-exposed cord blood monocytes. Moreover, …

Study Of Thermodynamic Binding Between Ader And Ades In Two-Component Antibiotic Sensor Of Antibiotic Resistant Strains Of Acinetobacter Baumannii, Konrawee Thananon

Chulalongkorn University Theses and Dissertations (Chula ETD)

The proteins AdeR (response regulator) and AdeS (histidine kinase sensor) play a crucial role in regulating the efflux pump, which is responsible for removing antibiotics from bacterial cells. This regulation occurs through a two-component regulatory system (TCS) involving autophosphorylation. Upon receiving external signals, AdeS undergoes autophosphorylation, leading to the activation of AdeR, which in turn initiates the expression of target genes related to the efflux pump. In this study, both enzymes from the reference strain of Acinetobacter baumannii (ATCC19606) and antibiotic resistant strains (H1074 and G560) were cloned and expressed in E. coli.
