It produces and secretes noradrenaline and adrenaline for the activation of the sympathetic nervous system. It is implicated in stress response. AFFERENT – Carrying information towards a particular group of neurones (compare efferent*). AGONIST – A neurotransmitter or a drug which binds to a receptor and triggers a cascade of intracellular signalling leading to changes in the membrane potential. AMINO ACID – A chemical made of carbon, oxygen, hydrogen and nitrogen, which is a building unit of all proteins* and other biologically important substances. AMINO ACID NEUROTRANSMITTERS – A group of fast acting neurotransmitters* which includes glutamate (excitatory) and GABA (gamma-amino butyric acid, inhibitory). AMNESIA – Loss of memory. AMYGDALA – A structure in the forebrain which is a component of the limbic* system. It is implicated in control of emotions. ANTAGONIST – A chemical which blocks receptors* and stops (inhibits) the effects of agonists*.
Despite concerted evolution that homogenizes a large number of rDNA gene copies, the presence of different gene variants within a genome has been reported. Characterization of an organism by defining every single variant of tens to thousands of rDNA repeat units present in a eukaryotic genome would be quite unreasonable. Here we provide an alternative approach for the characterization of a set of internal transcribed spacer sequences found within every rDNA repeat unit by implementing direct sequencing methodology. The prominent allelic variants and their relative amounts characterizing an individual can be described by a single sequencing electropherogram of the mixed amplicon containing the variants present within the genome. We propose a method for rational analysis of heterogeneity of multicopy genes by compiling a profile based on
Estonian University of Life Sciences Report on Soil Microflora By Katrin Vares Tartu 2013 Introduction The purpose of this report is to define soil microflora and establish the importance of it. Since the microorganisms clearly play an important role in preserving the balance of life, the next objective is to look into factors that influence this balance. Natural conditions and cultural impact could be considered as the variables that correlate the most with the activity and composition of microflora, hence some of the natural and cultural factors will be looked into a little more in detail. Definition, composition and importance of microflora Saunders Comprehensive Veterinary Dictionary (2007) cited by the online medical dictionary (2013) defines living microorganisms as that small that they can be seen only with a microscope and that maintain a more or less constant presence in a particular area that includes bacteria, vir
AMBER AND RUSSET - LATE COLOUR CHANGE GENES Copyright 2014, Sarah Hartwell The ancestors of the domestic cat were nondescript black/brown striped tabbies. Over the centuries, mutation produced a wide array of colours based on 2 different pigments. Eumelanin gives the blacks, browns and blues while phaeomelanin gives the reds, fawns and creams. A few other genes give further variations on those colours such silvers, colourpoints and solids/selfs. Mutations continue to occur and unexpected colours also turn up due to inbreeding where recessive genes, hidden for generations, start showing up. AMBER AND LIGHT AMBER During the 1990s, some purebred Norwegian Forest Cats in Sweden produced chocolate/lilac and cinnamon/fawn offspring. However, those colours are not found in the purebred Norwegian Forest Cat gene pool. Had the gene pool become polluted by someone, perhaps generations ago, breeding their Norwegian Forest Cat to another breed? Was it a spontaneous mutation? Crossing of those c
It is a native species to North America and was used by American Indians for an important, high-energy food source. Spanish explorers carried it with them to Europe. Russian agronomists were responsible for the first agricultural hybrids. These returned to the United States with Russian and German immigrants. Sunflower began as an important agronomic crop in the U.S. in the 1950's, starting in North Dakota and Minnesota. Seeds, kernel(tuum), what is the difference? The answer, there isn't a difference. Here is how the NSA refers to sunflower seeds/kernel: · In-shell means the seed is left intact with the "meat" of the seed still in the shell. It is normally roasted and seasoned. It is eaten as a snack by cracking the shell with one's teeth, discarding the hull and eating the delicious morsel within. 'Chew and spit' is a great American pastime, especially at baseball games and other outdoor events.
Formaldehyde Formaldehyde is a colorless, flammable gas at room temperature. It has a pungent, distinct odor and may cause a burning sensation to the eyes, nose, and lungs at high concentrations. Formaldehyde is also known as methanal, methylene oxide, oxymethylene, methylaldehyde, and oxomethane. Formaldehyde can react with many other chemicals, and it will break down into methanol (wood alcohol) and carbon monoxide at very high temperatures. Formaldehyde is naturally produced in very small amounts in our bodies as a part of our normal, everyday metabolism and causes us no harm. It can also be found in the air that we breathe at home and at work, in the food we eat, and in some products that we put on our skin. A major source of formaldehyde that we breathe every day is found in smog in the lower atmosphere. Automobile exhaust from cars without catalytic converters or those using oxygenated gasoline also contain formaldehyde. At home, forma
He has several specializations, including Strength and Conditioning Coach NSCA, Tennis and Skiing.
