Abstract:

Some purple bacteria species, such as Rhodopseudomonas palustris 2.1.6, produce light harvesting antenna (LH2) with unusual absorption spectra when they are grown under low-light intensities. This ability is often related to the presence of multiple genes encoding the LH2 apoproteins. This thesis describes isolation of pure stable LH2s from Rhodopseudomonas palustris 2.1.6 grown at different light intensities, determination of the polypeptide composition of high- (HL) and low-light (LL) LH2 complexes and characterisation their spectroscopic properties using various optical spectroscopies.

Increasing evidence suggests that overlapping genes is a common phenomenon in eukaryotic genomes too and are not restricted to prokaryotes alone. Here we determined overlapping genes in a set of orthologous genes in the genomes of human, chimp, mouse, rat, and dog and contrasted the patterns of overlapping between two principal types of overlapping genes, the same-strand-overlapping genes and different-strand-overlapping genes. The two types of overlapping genes are compared with respect to their frequencies, overlap lengths, region of overlap, and conservation of overlap in five species. Our

<p>Transmissible spongiform encephalopathies (TSEs) are fatal neurodegenerative diseases that include Creutzfeldt-Jakob disease, bovine spongiform encephalopathy and sheep scrapie. TSE disease pathology and mechanisms within the central nervous system (CNS) of an infected host largely remains unclear. At the cellular level, the uptake of protease resistant prion protein (PrP-res), which strongly correlates with infectivity and is a valid marker for TSE infection, is one of the earliest events that must occur during TSE infection.

Band-gap engineering of bulk germanium (Ge) holds the potential for realizing a laser source, permitting full integration of monolithic circuitry on CMOS platforms. Techniques rely mainly on tensile strain and n-type doping. In this thesis, we focus on studying diffusion-based phosphorus (P) doping of Ge using spin-on dopants (SOD), and tensile strain engineering using freestanding micro-electro-mechanical systems (MEMS)-like structures. Process development of a reliable SOD recipe was conducted using furnace and rapid-thermal annealing, and successful doping up to 2.5 x 10¹⁹cm⁻³ was achieved,

Abstract:

Collagen type I is an extracellular matrix (ECM) protein that affords tensile strength and biological scaffolding to numerous vertebrate and invertebrate tissues. This strength has been attributed to the triple-helical structure of the collagen type I molecules, their organization into fibrils, and the presence of inter-molecular, covalent, enzymatic crosslinks. There are several different types of these crosslinks; their composition is tissue-specific and dependent upon factors such as age and health. Furthermore, these enzymatic crosslinks tend to form specifically at amino/N- and carboxy/C-

<p> Bacterial strains from the <i>Mycobacterium tuberculosis</i> complex (MTBC) are functionally diverse and vary in both geographic distribution and potential to cause tuberculosis (TB) disease. <i>Mycobacterium africanum </i>—a lineage of the MTBC—is restricted to West Africa and causes slower progression to active tuberculosis (TB) after initial infection than other MTBC lineages. We hypothesized that this may be partly due to how bacterial strains from these lineages interact with the host immune response.

Background: Hereditary transthyretin amyloidosis (ATTR) is a lethal disease in which misfolded transthyretin (TTR) proteins accumulate as insoluble aggregates in tissues throughout the body. A common mutation is the exchange of valine to methionine at place 30 (TTR V30M), a form endemically found in the northern parts of Sweden. The main treatment option for ATTR amyloidosis is liver transplantation as the procedure halts production of mutated transthyretin. The disease is associated with marked phenotypic diversity ranging from predominant cardiac complications to pure neuropathy. Two differe

The biosynthesis of pyrimidines in Pseudomonas putida was investigated. In this study, pyrimidine requiring mutants were isolated by conventional mutagenesis and enrichment.

None of the intermediates of the pathway could supply the auxotrophic requirement of the strain; only preformed pyrimidines, metabolized via salvage pathways could suffice.

Transmissible spongiform encephalopathy (TSE) strains are defined by their biological properties on transmission to wild-type mice, specifically by their characteristic incubation periods and patterns of vacuolar pathology (‘lesion profiles’) in the brain.

Resistant bacteria are becoming more and more of a problem but treatment with antibiotics in combination may overcome and prevent resistance development.

A Pharmacokinetic-Parmacodynamic (PKPD) model that describes the dynamics of bacteria kill could be used to evaluate if the effects are additive or not. The model could later also be used to find optimal dosing for both of the antibiotics used alone

Abstract Type XIII collagen is a type II transmembrane protein which is expressed in many tissues throughout development and adult life.

To further characterize the function of this protein, we generated transgenic mice overexpressing it in normal and mutant forms.

Canine parvovirus type 2 (CPV-2), the aetiological agent of haemorrhagic enteritis in dogs emerged in 1978 worldwide.

In 2000, a new variant of CPV (CPV-2c) was detected in Italy and now circulates in other countries. Haemorrhagic enteritis in dogs is a major disease in South Africa and Nigeria. Both infection rates with CPV-2 and case fatality rates in young dogs are high. CPV-2 is a small, negative-sense, single-stranded DNA virus of 5.2kb long and a member of the Parvoviridae family,
