Cellular Respiration: A Stars Science Suitcase for High School Biology Students
… was to create a portable Science Suitcase on cellular respiration intended to supplement the current high school biology curriculum in the Dallas Independent School District. The Science Suitcase includes a narrated animation, a magnetic board game and printable student handouts. The Science …

Structural and biochemical studies on enzymes involved in natural product biosynthesis and cellular respiration
… the formation of the non-enzymatic end product. Cellular respiration is a critical components of a cellular organism’s ability to adapt and survive in its environment, as well as produce potentially useful natural products. It is not coincidence that many researchers are focusing on elucidating …

Nuclear Encoded Proteins Important in Mitochondrial Genome Stability
… mitochondrion is widely known to be the site of cellular respiration and the factory of cellular energy. Similar to the nucleus, mitochondria house genetic material (mtDNA), which is responsible for the production of proteins essential to mechanisms required for cellular respiration. Furthermore, …

Investigating the Role of Complex I Loss in Thyroid Tumorigenesis
Changes in cellular metabolism are considered one of the hallmarks of cancer. In 1924, Otto Warburg initially posited that defects in cellular respiration drive tumorigenesis after observing that tumor cells often perform aerobic glycolysis in culture. Since then, multiple studies have demonstrated …

Effects of ARVs and HIV on mitochondrial function and immune activation in monocyte derived macrophages in vitro
… function and metabolism. TFV increased cellular ROS, decreased cellular respiration, increased cell death, and decreased TNF-alpha. EFV decreased cellular respiration, decreased ATP production, decreased expression of complex I of the ETC, increased cell death, increased superoxide and …

Methane and carbon dioxide cycling in soils of the Harvard Forest
… in soils faster than it is converted to CO2 by cellular respiration, soil becomes a smaller GHG source and even has the potential to become a GHG sink. Not much is known about factors that drive soil to be a source or a sink of GHG. Soil temperature and moisture have both been shown to correlate …

The Metabolism of Normal and Malignant Tissue Culture Cell Strains
… cause of malignancy is an Interference with cell respiration. He stated that when there Is an Injury to cellular respiration the cell usually dies, but If the cell survives a tumor results. In 1956 he reaffirmed this hypothesis by stating that tumorogenesis involves two principal steps which are: …

AMP- Activated Protein Kinase (AMPK) Activation for the Treatment of Mitochondrial Disease
… biogenesis, mitochondrial function (e.g. maximal cellular respiration), and mitochondrial degradation. Thus, failing to increase the energy producing capacity of the cell, activation of AMPK may have induced an energy sparing mechanism.

Transcription Regulates Biased Mitochondrial DNA Inheritance
… DNA (mtDNA) is essential in eukaryotes for cellular respiration and ATP production by oxidative phosphorylation. Respiration is the preferred method for creating mitochondrial membrane potential, which is important for the import of nuclearly encoded proteins into the mitochondrion as well …

Effect of mitochondrial respiratory defecton hepatocellular carcinoma :Involvement of mtOGG1 and NUPR1
… an effect of mitochondrial dysfunction on hepatocellular carcinoma, the two projects were studied. The first project was to prove the involvement of mitochondrial DNA repair enzyme in hepatoma cell growth. To address this, it was employed several SNU hepatoma cells, which had been classified as …

The Effect of Trypsin on the Respiration of Tissue Slices
… primary explants as mentioned above and using cellular respiration as an indication of viability, we observed that the respiration of trypsin treated cells was consistently higher than the respiration of our controls. The tissue we were using was rat kidney. The controls were merely slices of …

Master regulators of neuronal maturation in NGN2 reprogrammed iPSC-derived iNeurons
… expression analysis implicated TFs in cellular processes hypothesized to promote neuronal maturation, including autophagy, oxidative stress response, cellular respiration and lipid metabolism. To assess the effects of transcription factor KO on the maturity of iNeurons, single-cell …

Avaliação do sinergismo entre os componentes da pasta ctz e o citronelol frente ao enterococcus faecalis
… enzymes, involved in the process of cellular respiration. After the checkerboard test, some results were verified as well as: additivity between tetracycline and chloramphenicol (IFIC: 0.625), indifference between tetracycline and eugenol (IFIC: 1.125), additivity between tetracycline …

Potassium cyanide inhibition of mixed bacterial populations
Many substances are known to inhibit cellular respiration. Relatively non-specific inhibitors are generally effective in proportion to the degree of penetration into the cell. However, the mechanism of action of cyanide is specific; cyanide irreversibly binds the iron group of cytochrome oxidase …

Infrared Spectroscopy of Cytochrome C Oxidase Intermediate States
… c oxidase is a critical player in the process of cellular respiration, performing proton translocation coupled to the four-electron reduction of O2 to H2O. To accomplish this catalytic task, specific changes at the active site influence chemical and physical changes throughout the protein, …

Mitochondrial Dynamics Imbalance as a Potential Driver of Neuronal Decline in the Aging Nervous System of Lymnaea stagnalis
… how age-related alterations in mitochondrial respiration, mitochondrial fission–fusion balance, and metabolic regulation contribute to functional decline in the central nervous system. Using the pond snail Lymnaea stagnalis as an invertebrate model of neuronal aging, the general hypothesis …

Phosphorescent semiconductor nanocrystals and proteins for biological oxygen sensing
Oxygen is required for cellular respiration by all complex life making it a key metabolic profiling factor in biological systems. Tumors are defined by hypoxia (low pO2), which has been shown to influence response to radiation therapy and chemotheraphy. However, very little is known about …

Probing Control of Glucose Feeding in Escherichia coli Cultivations
… is to exploit a characteristic saturation in the cellular respiration at the onset of acetate formation. By superimposing short pulses in the glucose feed rate, on-line detection of acetate formation can be made using a standard dissolved oxygen sensor. This information is used in a feedback …

Resveratrol slows cell growth by targeting the Warburg effect and stimulating mitochondria metabolism
… in mitochondrial network fusion, biogenesis and cellular respiration. This indicates that a metabolic reprogramming towards oxidative phosphorylation might be essential for RES antiproliferative effects. Indeed, when RES-induced metabolic reprogramming was prevented either by growing cells in …
