Cardiac Adaptation To Chronic Blockade Of Voltage-Gated, L-Type Calcium Channels In The Sarcolemma, Ji Zhou
Cardiac Adaptation To Chronic Blockade Of Voltage-Gated, L-Type Calcium Channels In The Sarcolemma, Ji Zhou
Electronic Thesis and Dissertation Repository
L-type Ca2+ channels (dihydropyridine receptors, DHPRs) in the sarcolemma are essential to cardiac excitation-contraction (E-C) coupling. Thus, Ca2+ influx through DHPRs upon cardiomyocyte excitation triggers Ca2+ release from the sarcoplasmic reticulum (SR) through ryanodine receptors (RyRs) to initiate myofilament activation and muscle contraction. Muscle relaxation occurs upon sequestration of Ca2+ back into the SR lumen by sarco/endoplasmic reticulum calcium-ATPase (SERCA) in the SR. As a treatment option for hypertension, long-term use of DHPR blockers is associated with increased risk of heart failure; underlying mechanisms are unknown. This research used male Wistar rats treated with verapamil (subcutaneously, …
The Roles Of Nitric Oxide Synthases (Nos) In Endochondral Bone Formation, Qian Yan
The Roles Of Nitric Oxide Synthases (Nos) In Endochondral Bone Formation, Qian Yan
Electronic Thesis and Dissertation Repository
Longitudinal growth of endochondral bones is controlled by the cartilage growth plate. Chondrocyte proliferation and hypertrophy, vascular invasion, formation of ossification centers and cartilage replacement by bone tissue are all important processes required for normal growth. These biological processes have to be tightly regulated or disturbances will lead to skeletal diseases. A large number of genes, growth factors and hormones have been implicated in the regulation of growth plate biology, however, less is known about the intracellular signaling pathways involved. Nitric oxide (NO) has been identified as a regulator of cellular proliferation, differentiation, migration, survival and metabolism in multiple cell …

Poisonous Rangeland Plants In San Luis Obispo County, Sara Litten, Amanda Ou
Animal Science
Poisonous Rangeland Plants in San Luis Obispo County is a comprehensive educational guide to rangeland plants that are toxic to domestic livestock. This guide begins with an exploration of how the biological systems are affected by the poisonous plant toxins. The biochemistry behind these toxins is included in the discussion. Next, reference material for fourteen plants that inhabit San Luis Obispo County is provided. This information includes specific toxins found in poisonous plants, affected animals, symptoms of poisoning, stages of growth, lethal dose, and distribution of the plant in California. This section of the guide is filled with helpful photos …
