Abstract:

Together with the current antibiotic resistance crisis, bacterial persistence appears to play an increasingly important role in the frequent failure of antibiotic treatments. Persister cells are rare bacteria that transiently become drug tolerant, allowing them to survive lethal concentrations of bactericidal antibiotics. Upon antibiotic removal, persister cells are able to resume growth and give rise to a new bacterial population as sensitive to the antibiotic as the original population. Interest in persister cells seriously increased in the past few years as these phenotypic variants were sh

Abstract:

Photoperiod manipulations are widely used throughout the Atlantic salmon (Salmo salar) farming industry as a means of producing a product of uniform quality all-year round. However, farmers still remain sceptical over their effectiveness to regulate growth and maturation during the on-growing stage. Furthermore, reports of a characteristic growth-dip following light exposure suggest that light may negatively affect the physiological performance of fish in the short-term. Thus, this thesis investigates the effects of light characteristics (spectral quality, intensity and photoperiod) on growth

Abstract:

Although sponges (phylum Porifera) are still often considered to be simple, inactive animals, both larvae and adults of different species show clear coordination phenomena triggered by both extrinsic and intrinsic stimuli. Moreover although sponges lack a nervous system, they show a range of behavioural responses that are affected by exogenously applied neuroactive compounds. Chondrosia reniformis (Nardo, 1847), a common Mediterranean demosponge, lacks both endogenous siliceous spicules and reinforcing spongin fibers and has a very conspicuous collagenous mesohyl mainly composed of collagen.

Abstract:

Despite considerable evidence in older populations that food intake can improve mental performance, little is known about the acute effects of feeding on cognition in the newborn period, a time when learning and memory are critical for discovering and adapting to everyday experiences. Feeding occurs well over 2500 times in the first year of life, raising the possibility that iterative effects on cognition may have cumulative effects over time. We recently demonstrated feeding enhancement of memory in two-to-three day old infants. Infants tested after a feed (versus before) displayed better mem

Biophysical processes related to the modulation of cellular mechanisms occur due to either presynaptic or postsynaptic effects. These processes involve some physiological phenomena whose different dynamics can potentially be distinguished via traces they leave in the power spectra of brain activity and/or connectivity fluctuations. Systematic expansion of NFT equations in terms of nonlinear response functions is formulated in Chapter 2 to enable a wide variety of nonlinear wave-wave and wave-neuron processes. This theory helps to handle neural quantities such as firing rates, neural field, som

Abstract The rationale for automatically monitoring anesthetic drug effects on the central nervous system (CNS) is to improve possibilities to gain objective information on a patient's state and to adjust the medication individually.

Current monitors are, for example, often based on heuristics and ad hoc solutions. However, a quantitative index for anes

Migraines are recurrent debilitating headaches that predominately afflict young women. The pathophysiology of migraines is still not well understood but is related to neurovascular dysfunction.

Serotonin (5-HT) is an endogenous vasoactive peptide with diverse physiology. In meningeal blood vessels, serotonin causes vasoconstriction, however in coronary arteries, serotonin causes both vasodilation and vasoconstriction. In diseased coronary arter

Whether any extrinsic factor contributes to the termination speed of the photoresponse is unknown.

Introdução: Diversos estudos indicaram consequências de alterações na nutrição materna durante a gestação sobre a saúde da prole adulta, tais como: hipertensão, doenças cardiovasculares, resistência à insulina, diabete melito e doença renal. No entanto, a literatura é pobre em avaliações decorrentes de modificações nutricionais maternas sobre a prole logo após o nascimento. Métodos: Ratas Wistar durante o período gestacional foram alimentadas com dieta hipossódica (HO - 0,15% de NaCl), normossódica (NR - 1,3% de NaCl) ou hipersódica (HR - 8% de Na Cl). Após o nascimento, nas primeiras vinte e

碩士<br>國立交通大學<br>生醫工程研究所<br>107<br>The nervous system plays many important roles in the human body. The nervous system is composed of numerous neuronal cells and is responsible for signal transmission.Through the communication between the nervous systems, the bio-energy can respond appropriately to changes in the external environment. Therefore, when the nerve cells are damaged or broken, the nerve fibers are damaged. In general, damaged nerve cells are repaired using a nerve conduit and are subjected to appropriate electrical stimulation. The main purpose of this study is to establish a system

In this study, the researcher uses the quasi-experimental method, 156 senior high school students studying in Taipei area are the subjects, there are 76 students in the experiment group who accept the conceptual change teaching, and there are 80

Abstract:

All companies have strategic assets comprising financial capital, physical capital, human capital and organisational capital which, when effectively utilised, contribute to the competitive advantage necessary to survive in a globalised economy. The manifestation of adverse factors in a company will impact detrimentally on the performance of these strategic assets. Since the 1980s, one factor has become prominent in the management of a company’s human capital, namely sexual harassment. Sexual harassment constitutes behaviour of a sexual nature that leads to, and perpetuates, a working envi

博士<br>國立臺灣大學<br>電機工程學研究所<br>96<br>It is interesting and meaningful to explore the brain function in various aspects. Meditation is a special mental operation which might promote body health. As yet, the internal mechanism and complete neurological interpretation still remain to be established. In this study, I chose Chinese Original Quiet Sitting (COQS) to be investigated by fMRI (functional magnetic resonance imaging) technique. Also, as COQS processes two different parts: a short period of silent recitation of religious mantra and mental imagination of receiving spiritual energy (named “Invi
