Advantages And Disadvantages Of Beauveria

The term Ololiuqui refers to the seeds of the Rivea corymbosa, a type of morning glory flower. The long vine supports white flowers and leaves shaped like hearts. Rivea corymbosa can be found in Mexico, Cuba, the West Indies and even along the North American Gulf Coast. Because the plant thrives most in wet tropical climates, it can also be found in Central America and the Amazon basin of southern Columbia.

One of them is Gleevec (Imatinib mesylate), a tyrosine kinase inhibitor, was called a “magical bullet”. This was the first targeted therapy drug used to treat cancer. It was invented in the late 1990’s, to treat “chronic myeloid leukemia and gastrointestinal stromal growth”. Imatinib is tyrosine kinase inhibitors. Tyrosine kinase is a protein that cells use to signal to each other to grow (Iqbal and Iqbal, 2014, p.1). It works by preventing a tyrosine kinase enzyme and therefore inhibits growth factor-induced receptor phosphorylation and blocks the PDGF/PDGFR and P13-k/Akt pathway (Kheradmand, et.al.2016, p.83). According to Richardson (2010, p.679), the drug Velcade was also known as “Bortezomib” is useful in the treatment of multiple myelomas. The main goal of this drug is to lower the tumor growth significantly. The American cancer society (2013, para.20) studies show Bortezomib is a “proteasome inhibitor”. It works by blocking or slowing down the action of proteosome is to break down protein in both healthy and cancerous cells. When proteosome activity is blocked, proteins in the cells accumulate. This accumulation may cause cells to stop growing and multiplying, and cause them to die and Sutent (Sunitinib) is a drug used to treat metastatic renal cell carcinoma. It is currently approved as a second-line treatment of MRCC. Sunitinib inhibits the vascular endothelial growth factor receptor and stops the growth of tumors (Kolesar, et.al. 2008, pp.123 131). It is considered as a multi- targeted kinase inhibitor because it is a type of VEGF inhibitor, an angiogenesis inhibitor, and it blocks an enzyme called tyrosine kinase. By doing all of this, it slows cancer growth and keeps tumors from making their own blood vessels to help them grow and spread (American

The gypsy moth (Lymantria dispar) is a highly disruptive species that can, and has played a distinctive role in the lives of many organisms. Included in these organisms are various deciduous trees and shrubs, wildlife species that share the same environment, and even humans. The gypsy moth destroys the beauty of woodlands via defoliation, alters ecosystems and wildlife habitats, and disrupts our own lives. It should therefore come as no surprise that the U.S. Department of Agriculture and many other agencies have taken huge steps to help diminish populations of this small, yet persistent species. In an effort to control these overwhelming populations, five chemical control agents have

Heavy feeding by the whitefly causes the death of numerous plants, or degradation in growth of older plants, because of the loss of sap. “When adult and immature whiteflies feed, they excrete honeydew, a sticky excretory waste that is composed largely of plant sugars. The honeydew can stick cotton lint together, making it more difficult to gin and therefore reducing its value. Sooty mold grows on honeydew-covered substrates, obscuring the leaf and reducing photosynthesis, and reducing fruit quality grade” (USDA 2016). By noticing the harmful effects that the whitefly has on the environment, many actions are being made to prevent the spread of further

Forests are carbon sinks, they absorb carbon dioxide, a major greenhouse gas, from the atmosphere through photosynthesis and store it in plant biomass and soils belowground. When the trees die, they stop absorbing and storing carbon dioxide, and as they decompose, they release some of the stored carbon dioxide back into the atmosphere (Suzuki & Moola, 2008). The mountain pine beetle (Aendroctonus ponderosae) is a primary agent of forest disturbance, a higher number of outbreaks occur due to favorable forest age and climate patterns (Progar et al., 2014). The mountain pine beetle (MPB) starts its attack when the female finds a pine tree (usually lodgepole) that is at least 80 years old. Upon finding the tree the female bores into it, while releasing a pheromone that attracts the male beetles. When the males arrive they, also release more pheromones to attract more females. The tree tries to defend its self by secreting a toxic resin. But the beetles carry spores of a blue-stain fungus in their mouths which they release as they bore into the tree, the fungus prevents the tree from transporting nutrients and water. The beetles lay eggs under the tree’s bark, and when the larvae hatch, they feed on the blue fungus until they are mature enough to leave the now dead tree (Aukema et al., 2006).

One of the largest responsibility for any beekeeper is to ensure that their bees are healthy. This means that Integrated Pest Management is a necessity to ensure a healthy beehive. The pros of Integrated Pest Management are decreased use of chemicals in the beehive, more sustainable, more economical in long run, less chance of hive product contamination, less exposure by beekeeper to chemicals and extends the useful life of chemicals used by lengthening time between applications. The cons of Integrated Pest Control are additional time and commitment required to implement, often requires multiple strategies and evaluation required. One disease and one pest that are extremely devastating to any beehive is American Foulbrood and wax moths.

Cryphonectria parasitica, a filamentous, ascomycete fungus, is the causal agent of the chestnut blight5,14 which was introduced to North America from Japan circa 190412,14.The chestnut blight infects all members of the Castanea family14, and some members of the genus Quercus though C. parasitica infections are superficial14. A C. parasitica infection typically begins at a branch node or wound in the tree’s bark 14. Once a spore has entered the tree, hyphal growth begins14. When the fungi’s hyphae reach the cambium, the xylem and phloem are blocked, cutting off the transport of water and nutrients and a sunken canker is formed14. Eventually, the lack of water and nutrients kills the tree above the point of infection14. As a fungus, C.

In the past, most of the cancer drugs were developed to hinder the growth of tumors. The main strategy was so called “targeted therapies, which interfere with genetic signals that act like accelerators, causing tumors to grow.”1 However, because there are too many pathways and signals that can act as an accelerator of the cancer growth, a single drug was usually not enough to suppress the cancer.

With a growing awareness of the importance of our environment, more people than ever are looking for natural products and attempting to eliminate harmful chemicals from their lives. This can clearly be seen with the move towards using bio-insecticides to kill pests in their homes. The following are three reasons to make the switch to bio-insecticides, especially for a beg bug problem.

Fungal diseases can be detrimental to the health of many organisms in the ecosystem and extremely hard to control the spread. Three once commom tree species in North America have been devastatingly impacted by the spread of Dutch Elm disease, Chestnut blight, and Butternut canker.

This species is commonly used in killing pests, insects, that are bothering human beings. An example, could be people who have bedbugs as a problem; that would spray the species onto their mattress which will then infect the bugs with the disease White Muscardine, therefore killing them. This works when the spores of this fungus touch with the skin of the insects, they grow directly through the skin to the inner body of the insect. At this point, the fungus spreads throughout the body of the insect, creating toxins inside it's body, consequently killing it. This shows that Beauveria does not need to be eaten to affect the host, but just needs to touch their host. Once the fungus has killed its host, it grows back out through the softer pieces

The research is a novel idea and approach to control harlequin bug which is a vegetable pest that feeds on foliage. In his study, they are trying to understand first how harlequin bug makes pheromones, and second how to transfer murgantiol biosynthesis to plants.

When studying medicine it is important to know how the pharmaceutical drug will affect the body, how quickly the drug will work, and what are the short term and long term effects of the drug on the disease. It is important to know the structure of the molecules, to see exactly where the inhibitor will bind, or if it will even bind at all. In the experiment, Structure Based Approach to the Development of Potent and Selective Inhibitors of Dihydrofolate Reductase from Cryptosporidium, they studied the crystal structures of the inhibitors and used computational analysis to determine which in inhibitor would bind the best. The overall goal is to make sure that the inhibitor binds to the correct active site, and that it is the only site.

Cancer has become an epidemic across America. About 13 million Americans have cancer and a little over 1 million are diagnosed every year. For years Oncologist have been looking for treatments to cure this horrible disease(American Cancer Society, 2013). Chemistry has such a major impact on the research of cancer. The chemistry within Oncology & Cancer Research has greatly increased our knowledge and capabilities for developing new treatments or actually finding a significant cure (American Cancer Society,2013). This paper is explaining how chemistry is used to seek out cancer cells, treat, and also inform how the different chemicals are affecting our body.
