Digestibility of calcium and digestible calcium requirements in pigs
… of inclusion of microbial phytase, monocalcium phosphate had the greatest (P < 0.05) STTD of Ca. The STTD of Ca in dicalcium phosphate was greater (P < 0.05) than in calcium carbonate, Lithothamnium calcareum Ca, or in a sugar beet co-product, but no differences were observed among the …

Characterization of calcium-silicate-hydrate and calcium-alumino-silicate-hydrate
… objectives of this thesis were to synthesize calcium silicate hydrate (C-S-H) and calcium aluminosilicate hydrate (C-A-S-H) and characterize their structures with varying Ca/Si ratios and aluminum content. As a secondary objective, carbonation behavior in synthesized C-S-H was studied. C-S-H …

The Secretory Pathway Calcium ATPase 2C promotes increased cytosolic calcium levels
… acinar cell exocytosis requires precise calcium (Ca2+) signals. When cytosolic Ca2+ levels remain high, cellular functions are disrupted, which is associated with initiation of pancreatitis. Ca2+ signals are achieved through regulating endoplasmic reticulum (ER) stores, Ca2+ATPases, and …

DOES CALCIUM INFLUX THROUGH T-TYPE CALCIUM CHANNEL INDUCE CARDIOMYOCYTE PROLIFERATION?
… study is to investigate on how TTCCs (T-type calcium channels) affect cardiomyocyte proliferation. In mice after birth, the major TTCC expressed in the heart is Cav3.1/α1G, and therefore we used Cav3.1/α1G transgenic (TG), knockout (-/-) and wild type mice respectively to define the role of …

Study of Presynaptic Calcium Channels and a Novel Calcium Channel Calhm1
Calcium signaling is essential for all cellular processes. In brain these processes include basic synaptic transmission, modification of established synapses, elimination of synapses as well as elimination of whole neurons by way of apoptosis. In this thesis, we have studied two of these processes. …

Stabilization of non-plastic soils with calcium hydroxide-calcium carbonate mixtures
The influence of calcium carbonate on the properties of four non-plastic lime-stabilized soils was studied. The four soils span a range in mica content and sand content. It was found that carbonate generally increased unconfined compressive strength and secant modulus of elasticity when included as …

Early Osteoclast Responses to a Calcium Supplemented Meal in Calcium Deficient Rats
… cells responsible for the mobilization of calcium from bone (bone resorption). It is a well known fact that bone diseases (i.e. osteoporosis and osteopetrosis) occur as a result of unbalanced cellular activity. The implicated bone cells include osteoblasts (bone forming cells) and …

Hair calcium concentration is associated with calcium intake and bone mineral density
Background : Calcium concentration in hair representing intracellular calcium level, is associated with systemic diseases such as coronary artery disease. However there is no previous study to show how hair calcium level is regulated. The aim of the study is to investigate whether hair calcium …

Calcium Dyshomeostasis In Neurodegeneration
<p>Neurodegenerative diseases, despite constituting a major and growing cause of mortality globally, have few effective treatments. In order to develop novel therapeutics to combat neurodegeneration, a better understanding of the molecular mechanisms underlying these diseases is needed. Neurons …

Calcium carbonate precipitation kinetics
… and Reddy is presented to describe the rate of calcium removed from water in CacO3; precipitation. The mass of CaCO3; precipitated at any moment was obtained by monitoring pH and utilizing this in the equilibrium equations for the Ca - H2CO3 system including ion pairing and ionic strength …

Calcium Channel Gamma(6) Subunits Are Unique Modulators of Low Voltage-Activated Calcium Current
The calcium channel gamma (gamma) subunit family consists of eight members whose functions include modulation of high voltage-activated (HVA) calcium currents in skeletal muscle and neurons, and regulation of AMPA receptor targeting. Cardiac myocytes express three gamma subunits, gamma 4, gamma6 …

Calcium Triggered Synaptic Vesicle Exocytosis
Neurotransmitter release is triggered by the action potential induced influx of Ca 2+ into nerve terminals. One of the central questions in neuroscience is how Ca 2+ promotes synaptic vesicles from rest to fusion leading to release of neurotransmitters. In this thesis, I first addressed if …

Calcium homeostasis in Pichia pastoris
… In this study, we examined the effects of calcium and magnesium on growth, heterologous protein expression, and calcium homeostasis in P. pastoris . The divalent cations calcium and magnesium are responsible for diverse roles in in the function of the cells in eukaryotes. Although it is …

Calcium homeostasis in Escherichia coli
<p>While the role of calcium ions as secondary chemical messengers has been well described in eukaryotic cells, little is known about calcium homeostasis in bacteria at the physiological and molecular level. No calcium influx gene has been identified so far. This dissertation focuses on calcium …
