Anthony Alvarado Bio 1A Chronic oxidative stress via hydroxyl radical and imbalanced redox homeostasis Redox hemostasis has been shown to be an important factor in the overall aging and neurodegeneration processes in mammalian models; such as, Alzheimer’s and Parkinson’s. As a result, redox homeostasis has been a key point of interest in current research. Redox homeostasis is the balance between electrophiles and nucleophiles in a system, more importantly in a biological system. These…

Discussion The mechanism of arsenic-induced neurotoxicity is not well defined. Several metabolites of arsenic are able to pass through the blood-brain barrier and accumulate in the hippocampus and some other locations [13]. This affects the intracellular Ca(2+) homeostasis and ultrastructures of hippocampal neurons. In relation to the amino acid neurotransmission, report reveal that arsenic-induced excessive glutamate accumulation in the extracellular space induces excitotoxicity [29]. Arsenic…

I chose to write my paper on the chapter two context involving a friend ordering alcohol while in the second trimester of her pregnancy. Many people believe that a glass of wine every now and then is not a bad thing to do during pregnancy, even some doctors say that it is tolerable. It may not be worst possible thing to ingest while pregnant, but in your second trimester the baby is still developing crucial parts of the body and the bones are becoming more dense. I think avoiding substances like…

Benzene is the simplest aromatic hydrocarbon that is represented with the formula C6H6. It was discovered in 1825 by a British scientist, Michael Faraday, who extracted it from crude oil by applying pressure, and named it “Bicarburet of hydrogen”. However, its chemical synthesis did not start until in 1843, Charles Mansfield, discovered a method to extract benzene from coal tar. Since its industrialization, benzene is produced and used in many industrial processes. Today, plastics, resins, dyes…

•Background and aim Soil salinity is one of the major environmental obstacles that limit the crop productivity. A pot experiment was conducted with an aim to explore the ameliorative effects of exogenously applied sodium nitroprusside (SNP) concentration against salinity stress in Brassica napus (L.) cv. Pactole. Methods Plants were grown under greenhouse conditions in plastic pots and were exposed to ***** mM NaCl. Further, ***** days old plants were sprayed with sodium nitroprusside (SNP,…

Arsenic contamination and possible remediation Victoria Reyes Texas A&M International University Abstract Arsenic can be found in many places on Earth. This includes from natural sources and as a by-product from different anthropogenic activities. The fact that arsenic can be found so commonly on Earth has lead to the contamination of several countries’ drinking water. This has put many people at risk for arsenic poisoning. There are many complications that come from the continuous ingestion…

It is becoming evident that humans are continuously exposed to a plethora of chemicals from food, medicinal agents, occupational activity and contaminated sites. Exposure to chemicals begins in utero and continues throughout life. Toxicological risk assessment of individual chemicals provides the quantitative estimate of its possible effects on human health. When humans are exposed to chemicals, they are not exposed to a single chemical only, but simultaneous or sequential exposure occurs to a…

Title: Choosing the Best Cream for Scars Description- There are a number of factors that you need to consider when making the choice of the best cream for scars. Cream for scars are considered the best and the most effective treatment for the ones suffering from ugly scars. There are different brands of these creams available throughout the market and most of them provide good results in diminishing scars. However, it is to be noted that most creams intended to do way with scars generally take a…

Epilepsy is a disorder defined by many as having recurrent and unprovoked seizures (apgar pg 296). These seizures can range from very physical and dramatic seizures to light twitches or no movement at all (kirka…). Despite the obvious physical issues of this disease, its problems start in the brain, and the seizures are usually categorized by where they affect the brain. There are generalized onset seizures, which start on both sides of the brain, focal onset seizures, which start in one…

Nanoparticles (NPs) have piqued the interest of scientists because of their distinct physical, chemical and biological properties when compared to bulk material. These differences in characteristics can be attributed to the high surface-to-volume ratio (SA:V) of NPs compared to bulk material. Since NPs have a higher SA:V than bulk material, they are more reactive than their bulk counterparts; therefore, the surface characteristics of NPs can be easily manipulated. (Xuefei et al, 2014) Metal NPs…
