We first evaluated whether Honokiol treatment was toxic to the APP-CHO cell line. Cells were treated with various concentrations of Honokiol (0.5 μM, 1 μM, 2 μM, 5 μM, 10 μM and 20 μM) for 24 h and cell survival was determined by Prestoblue® assay (Fig.1A). As shown in Fig.1A, when exposed to Honokiol concentrations of 10 μM or lower, the viability of APP-CHO cells was the same as untreated control cells. However, a significant decrease in cell viability was observed with 20 μM Honokiol…

Introduction Enzymes are specialized proteins that act as catalysts. Enzymes are a key part of many biological processes because they are capable of lowering the activation energy of a chemical reaction. By lowering the activation energy enzymes are able to speed up reactions allowing for multiple chemical processes to occur at a faster rate in many living organisms. Enzymes work by binding to specific molecules called substrates. The enzyme observed in this experiment was amylase and its…

Introduction What are enzymes and how do they affect reactions? Enzymes force reactions, in cells, to maintain a speed necessary for life. Enzymes can also be considered catalysts because they require the reactions to arise faster without themselves changing. For this experiment, the substrate in the enzymatic reaction was sucrase, and it will be causing sucrose to change resulting in the following equation: Sucrose → Glucose + Fructose Where the arrow is in the equation indicates the enzyme,…

In this instance, a thought instructs energy to form matter, producing a chemical reaction, which produces a physical reaction/feeling of nervousness. It started as a thought but manifested as a chemical and physical reaction. Some of the signs/symptoms you may experience when not living as your authentic self can include; • Emotional/mental symptoms such as: feelings of unrest, boredom…

Zedina Martin Dr. Adair English 201 8 March 2018 When there is love anything is possible, not! The poem “The Passionate Shepherd to his love” is a pastoral and romantic poem by Christopher Marlowe that has a focus on the Shepherd’s love. The speaker of the poem is the Shepherd. The poem “The Nymph’s Reply to the Shepherd” is a poem by Sir Walter Raleigh in response to Marlowe’s poem. A Nymph is the speaker of the poem. Raleigh’s poem is a direct mockery of Marlowe’s poem and all the claims and…

John Dalton was an English chemist, physicst and meterologist. Might be familiar with "Daltons Law of Partial Pressures" which is a law still used today, or "Daltonism" also reffered to as color blindness. Dalton was born in Eaglesfield, England on September 6th, 1766. He lived a great life until his death on July 27, 1844 as he died of a stroke in Manchester, England. John Dalton was born into a strong Quaker family (family thats known as "Religious society of friends". John had 2 survivng…

the cell that are more hydrophobic (water-fearing) and other parts that are hydrophilic (water-loving). The cell membrane is mostly hydrophobic and the cytosol is mostly hydrophilic. We made predictions of where the drugs would reach giving their chemical structure. This…

In Co(NH3)6Cl3, since the complex has a total charge of zero, ammonia has an oxidation number of 0, chlorine has an oxidation number of -1, cobalt has an oxidation number of +3. Therefore, there are four electrons in the d orbital of a cobalt in this complex. Figure 8 gives the possible high spin and low spin combinations for four d orbital electrons. The high spin config- uration has four unpaired electrons and the low spin configuration has two unpaired electrons. Figure 7. High and low…

In Greek, this is an onomatopoetic word. This means it’s a word that imitates the sounds associated with the objects or actions it refers to (like the word buzz in English sounds like the sound a bee makes when he is flying around). The word zeloo imitates the sound of boiling water, and it literally means to bubble over because it’s so hot! In a positive sense, zeloo is to be zealous in the pursuit of good, to desire earnestly, to strive after, to pursue, to be eager to possess. In the…

Electrical properties Figure. 8 shows the temperature dependence of resistivity of the Co(II), Ni(II) and Cu(II) complexes. As seen, the data reveal a semiconductor behavior where the resistivity decreases with the increases of temperature. The decrease of the electrical resistivity with increase of temperature is resulted from the increase of the charge carriers that can overcome the energy barrier and participate in the electrical conduction where in metal complexes, the metal…
