Also during this stage mild personality changes may occur, along with withdrawal from social interaction. The person will also experience memory loss that could affect their job, and the…

strongest genotoxic effect occurred when HepG2 cells were specifically exposed to PT, which caused an increase in cellular components in all four DNA damaged base pairs (Hreljac et al. 2008). Additionally, toxicity of this pesticide can inhibit acetylcholine esterase in cells in the nervous system that can result in a decrease in nerve impulses being transmitted (Pope…

Pharmacodynamics Pharmacodynamics refers to the mechanisms of drug action. Loratadine is a “non-sedating” tricyclic anti-histamine that possesses competitive, selective, peripheral H1-receptor antagonistic activity. The onset of the anti-histaminic effect occurs 1-2 hours after the administration of the drug and the peak effect occurs between 8-12 hours. Loratadine is known as a long-acting anti-histamine as its anti-histaminic effect can persist for up to 24 hours. Histamine is produced from…

that its use for amyloidosis preventing [29,30]. The distribution of colchicine in the brain is unequal and in the hippocampus (the area that most affected in AD) is three times higher than in other brain regions [31]. The drug selectively blocks acetylcholine transferase in the basal forebrain and hippocampus, which these regions are responsible for memory [32]. When colchicine penetrates to subarachnoid space showed symptoms, including jumpy and irritable behavior, become aggressive and loss…

My phone is sitting next to me on my desk when I hear it begin to ring. I pick it up in my hand and look at the screen to see who is calling me. When I recognize my mother’s caller ID, I tap a button to accept the call. I bring the phone to my ear and hear my mother’s voice through the speaker. We talk for a few minutes, and then eventually we say goodbye. I end the call and place the phone back onto my desk. The body system that enables me to successfully complete this phone call is the…

Neuromuscular symptoms are the most common presenting problem of hypermagnesaemia and magnesium intoxication. Magnesium prevents the release of pre-synaptic acetylcholine from both sympathetic and neuromuscular junctions.(93)Hypermagnesaemia causes blockage of neuromuscular transmission and depresses the conduction system of the heart and the sympathetic ganglia. Clinically, one of the earliest effects of magnesium…

Every year one in six Americans get food poisoning . Food poisoning occurs due to the contamination of food through microorganisms. Botulism is a form of food poisoning caused by the microorganism Clostridium botulinum. Clostridium botulinum is a gram-positive bacterium, bacillus in shape, and is an obligate anaerobe.1 The bacterium can produce endospores, making it resistant to microbial control methods. Clostridium botulinum survives in nonliving reservoirs1 . It is commonly found in soil and…

1. Discuss what a neuron is and the functions of its basic parts (dendrites, soma, axon, myelin sheath). A neuron is a nerve cell. There are about 10,000 specific types of neurons, but there are three most common neurons: sensory, motor, and interneurons. A sensory neuron sends signals to help your brain understand what is going on around you in your environment. Sensory neurons are what make up your senses, (smell, touch, see, taste, and hear.)…

Three classes of hallucinogens relate to “hallucination-producing” drugs, particular neurotransmitter systems in the brain. Describe these three categories and include one example of a hallucinogenic drug in each. (20 points) The three classes of hallucinogens are Psychedelics, Dissociatives and Deliriants. Cannabis (marijuana) which falls under Psychedelics has a compound called tetrahydrocannabinol (THC) which affects the endocannabinoid (EC) system. In the EC system, neurons communicate…
