What Is Metronidazole?

Drug therapy relies on the principle of selective toxicity, where the effects of the drug are only harmful towards the foreign parasite and not at all to the host. By comparing the effects of different drugs on various parasitic organisms we are able to distinguish the type of disease or infection that is present as well as the mechanism of action that takes place by each drug in question. The drugs may function by interacting with enzymes such as transpeptidase and thymidylate synthetase, for example Penicillin and 5-FU function respectively. The effectiveness can be quantified by measuring the zones of inhibition created by the drug on the plate of the bacteria or fungus. This is the area where there is no growth due to the action of the drug. The discovery that the Micrococcus-luteus is classed as a bacteria was made apparent due to Penicillin’s success in inhibiting it’s growth. The action of the Amphotericin solely on the Pythium, gives reason to believe that it can be grouped with fungal growths.

There are barriers to treating BV that add to the challenges providers face when treating the condition. Unfortunately, metronidazole efficacy is decreasing due to resistance.13 Certain organisms have been

The purpose of this report is to analyse the growth of the bacteria known as Citrobacter Freundii as well as distinguishing what antibiotics effect its growth. This will be done so by answering the following question after completing its associated experiments. This question includes: what antibiotics are most effective in denaturing the bacteria? It has been predicted that chloramphenicol will be the most effective due to the fact that its medical uses are treating meningitis which is an infection caused by Citrobacter freundii. After conducting the experiments it was found that the chloramphenicol antibiotic was the most effective in denaturing the bacteria, although streptomycin was also affective. However, none of the other antibiotics were able to halt the growth of the bacteria.

As the NFL grows in infamy from their many concussion scandals, the misusing of prescription drugs is overshadowed, but still remains as a major issue in the NFL. A huge problem facing the NFL today is the ill advised use of painkillers as it affects former players and current players alike. If nothing is done to stop this dilemma, players will continue to be affected by the accoutrements of painkillers. Only through DEA investigations, increased restrictions on prescription drugs, and increased monitoring of player’s mental health, will we end the epidemic of the misuse of painkillers in the NFL.

Donepezil hydrochloride is the active ingredient in the prescription drug Aricept, a common drug used to treat mild, moderate, and severe Alzheimer’s disease and other forms of dementia. It is a reversible inhibitor of the enzyme acetylcholinesterase, which is responsible for the breakdown of the neurotransmitter acetylcholine. Increased levels of acetylcholine are believed to relieve the effects of Alzheimer’s disease.

The interaction of isothiazolone biocides with microbial cells proceeds via several sequential reactions. Initially, a biocide molecule reacts with a thiol group to form a disulphide linkage with the biocide. This structure then interacts with a second thiol group to establish a new disulphide linkage. Following this, the cell releases the biocide as a mercaptoacrylamide. The mercaptoacrylamide derivative of CMIT tautomerizes to a thioacyl chloride under physiological conditions. The thioacyl chloride is highly reactive and proceeds to interact with other cell macromolecules. The ability of CMIT to degrade to a thioacyl chloride might account for it’s much greater antimicrobial activity when compared to BIT or MIT. (Daniel, 1997)

These mutations, no matter what process that has led to their occurrence, block the action of antibiotics by interfering with their mechanism of action (1). Currently, antibiotics attack bacteria through one of two mechanisms. In both mechanisms the antibiotic enters the microbe and interferes with production of the components needed to form new bacterial cells. Some antibiotics act on the cell membrane, causing increased permeability and leakage of cell contents. Other antibiotics interfere with protein synthesis in cells. They block one or more of the steps involved in the transformation of nucleic acids into proteins.

Genotoxicity is the property of chemical agents that causes damage to DNA which then causes usually deleterious mutations. Scientists study the genotoxicity of chemicals to limit the exposure of materials that may be harmful to humans. While there are already two tests designed to determine the genotoxicity of a certain chemical agent there are advantages and disadvantages to each. The Ames test is simple and effective, making it easier for scientists to do multiple tests in a shorter period. But the Ames test uses Salmonella typhimurium, a bacterium, and some chemical agents that are harmful to bacteria are safe to eukaryotes and some that are genotoxic to

*Tigecycline (TIG), a derivative of minocycline, overcomes most of the known tetracycline resistance mechanisms. The discovery of TIG represented significant progress, because it is active against a wide spectrum of Gram negative and Gram positive pathogens, especially multidrug-resistant strains. Tigecycline, similar to tetracycline shows antibiotic properties, but is not affected by tetracycline resistance mediated by efflux or ribosomal protection proteins. This allows TIG to evade the common ribosomal protection mechanisms associated with resistance to

Thiazolidinediones or glitazone are a class of oral antidiabetic agents. Thiazolidinediones are a synthetic ligand for the peroxisome proliferator-activated receptor g (PPARg). Troglitazone was the first thiazolidinedione antidiabetic agent that approved for the clinical use by the US in 1997. Troglitazone decreased hepatic glucose production, lowers blood glucose levels through increased glucose uptake by skeletal muscle, and increased insulin sensitivity of the target tissue in animal models of metabolic impairment. These pharmacological effects are exerted through the PPARg-dependent transcription of genes which involved in glucose and lipid metabolism and also in energy homeostasis. Troglitazone represents a model of an idiosyncratic

Chagas disease presents two clinical phases, the acute phase, which appears shortly after and a chronic phase, which can last for several years or even decades.. The symptoms of the chronic phase, approximately 30 % of affected population,include cardiomyopathy, heart failure and digestive-tract abnormalities, such as megacolon and megaoesophagus. The severity of these symptoms generally determines the morbidity of the disease (2, 7, 8). Currently, the only two clinically available drugs for treating the infection are benznidazole and nifurtimox. Both drugs, despite various side-effects, are effective during the acute phase, but their efficiency during the chronic phase, when most cases are diagnosed, is controversial, due to the low compliance of patients to the long-term treatments that are required for the successful treatment of infection (1, 3, 7). Therefore, it is important to identify new drugs for T. cruzi. DNA binders are one of the most widely studied classes of agents characterized by biological effects, such as antiprotozoal, antiviral, antibacterial and antitumoral activity. Beginning in the 1970’s, a large number of diamidine derivatives were synthesised to identify more

Tramadol hydrochloride, an atypical synthetic opioid member of the aminocyclohexanol group, is a centrally acting analgesic compound that was initially synthesized in 1962 by Grünenthal Company and marketed in Germen since 1977 [1-3] and has been launched in Egypt since 1995 [4].

Antibiotics are one of the most frequently prescribed medications, however little is known about the secondary effects. Sulfamethoxazole-Trimethoprim (SMZ-TMP) is a common oral antibiotic, and ecological studies have proved that the unmetabolized portions are secreted via urine and feces, suggesting that residue remains throughout the digestive tract. Horses are hindgut fermenters and rely heavily on their symbiotic interaction with the bacteria in their cecum to break down structured carbohydrates to produce volatile fatty acids which are used by the horse as an energy source. Possible interaction with this microbiome by antibiotics is of great concern, potentially leading to antibiotic associated diarrhea (AAD), colic, and inflammatory vasoconstriction.

Singing has lots to do with math. The rhythm, the beat, the notes, and even the strum of a string has a mathematical formula.
