Four Short Stories About Maturation
This project is meant to represent a creative culmination of my time in undergrad. I wanted to do a project involving creative writing and storytelling and I also wanted to use the opportunity to reflect on my time I’ve spent in college. As such, each of the stories here is based on a specific …

Cerebral Microcirculatory Effects of Maturation
… to 5-HT and NE decreases significantly with maturation, but does not vary with branch order. These age-related changes were associated with a decrease in affinity and maximum response in 2B and 4B segments of 5-HT and NE contracted arteries, respectively. Norepinephrine and 5-HT occupancy at …

Egg Maturation and Fecundity in Etheostoma
The problem of estimating fecundity in darters (Etheostoma and Percina) was discussed and a new definition of fecundity proposed. Estimates of fecundity in four species of Etheostoma was determined by multiplying the number of oocytes (≥0.3 mm) recruited per week times the number of weeks in the …

Postnatal Maturation Modulates Cerebrovascular Myogenic Tone
… study focused on the main hypothesis that maturation decreases contractile reliance on calcium influx and myofilament Ca2+ sensitivity, and increases reliance on release of calcium from intracellular stores to develop and maintain pressure-evoked myogenic tone in rat cerebral blood vessels. …

Neuroligins Determine Synapse Maturation and Function
Dieses Projekt untersucht die Rolle von Neuroliginen im Atmungsnetz des Hirnstamms von NL 1-3 und NL 2 herkömmlicher Knockout Mäuse. Die Auslassung aller drei Neuroligin- Gene führt zu einem lebensgefährlichen Phänotypus, der am wahrscheinlichsten einen Atmungsausfall bedingt, wie wir in unseren …

Engineering Organoids for Stem Cell Maturation
… non-invasively. However, iHLCs require further maturation before they can be substituted for PHHs due to their lower liver-related functions and immature characteristics. Existing maturation approaches require the administration of chemical mixtures that can be up to a million times higher than …

Investigation of Escherichia coli [NiFe]-Hydrogenase Maturation
… for anaerobic growth and pathogenesis. The maturation of [NiFe]-hydrogenase requires at least seven dedicated accessory proteins to assemble and insert the components of the NiFe(CN)2CO catalytic site. The penultimate maturation step is the delivery of nickel to a primed hydrogenase …

Investigation and Modelling of Fetal Sheep Maturation
In this thesis, I study the maturational changes of the fetal sheep ECoG (electrocorticogram) in its third-trimester of gestation (95-140 days of gestation), investigate three continuum models for electrical behaviour of the cortex, and tune the parameters in one of these models to generate the …

Maturation of GABAergic signaling during brainstem development
Im adulten Zentralnervensystem wirkt γ-Aminobuttersäure (GABA) als hemmender Neurotransmitter über ligandgesteuerte GABAA-Rezeptorkanäle und G-proteingekoppelte GABAB-Rezeptoren. Neue Studien haben aber gezeigt, dass während der Entwicklung GABA im frühpostnatalen ZNS auch exitatorisch wirken kann. …

Role of Zmpste24 in Prelamin A Maturation.
… the second endoproteolytic step in lamin A maturation. <em>In vitro</em> reactions with this substrate and insect cell membranes bearing recombinant Zmpste24 demonstrate that Zmpste24 may possess the ability to directly catalyze the second endoproteolytic cleavage. Previous studies on …

Structural investigations of adenosylcobalamin-dependent enzyme maturation
… target metalloenzyme. This thesis focuses on the maturation of methylmalonyl-CoA mutase (MCM). In humans, MCM is the only known adenosylcobalamin (AdoCbl)- dependent enzyme; mutations or deletions of MCM or any metallochaperones involved in its maturation lead to methylmalonic aciduria, an inborn …

PREFRONTAL ACTIVITY IN COGNITIVE FUNCTION: MECHANISMS AND MATURATION
… of puberty and the completion of developmental maturation of male rhesus monkeys were evaluated with a series of morphometric, hormonal, and radiographic measures. We evaluated working memory with the oculomotor delayed response task, which requires subjects to make an eye movement towards the …

Structure, Assembly, and Maturation of High -Density Lipoproteins
High-density lipoproteins (HDL) are protein-lipid particles that are involved in the transport of cholesterol in the blood. They are of great importance in the treatment of coronary heart disease as low levels of HDLs are a known risk factor for the development of arteriosclerosis. Little is known …

Factors influencing in vitro maturation of pig oocytes
… and the role of estradiol-17$\beta$ on in vitro maturation of pig oocytes. Cumulus oocyte complexes (COC) were obtained by aspiration of 2-5 mm follicles. The oocytes were cultured for 42 hours at 38.5$\sp\circ$C in mTCM-199 supplemented with LH, FSH, follicular fluid, fetal calf serum and …
