    Buzzle – Zoology Terms – Glossary of Biology Terms and Definitions http://www.buzzle.com/articles/biology-terms-glossary-of-biology-terms-and- definitions.html#ZoologyGlossary Biology is the branch of science concerned with the study of life: structure, growth, functioning and evolution of living things. This discipline of science comprises three sub-disciplines that are botany (study of plants), Zoology (study of animals) and Microbiology (study of microorganisms). This vast subject of science involves the usage of myriads of biology terms, which are essential to be comprehended correctly. People involved in the science field encounter innumerable jargons during their study, research or work. Moreover, since science is a part of everybody's life, it is something that is important to all individuals. A Abdomen: Abdomen in mammals is the portion of the body which is located below the rib cage, and in arthropods below the thorax. It is the cavity that contains stomach, intestines, etc. Abscission: Abscission is a process of shedding or separating part of an organism from the rest of it. Common examples are that of, plant parts like leaves, fruits, flowers and bark being separated from the plant. Accidental: Accidental refers to the occurrences or existence of all those species that would not be found in a particular region under normal circumstances. Acclimation: Acclimation refers to the morphological and/or physiological changes experienced by various organisms to adapt or accustom themselves to a new climate or environment. Active Transport: The movement of cellular substances like ions or molecules by traveling across the membrane, towards a higher level of concentration while consuming energy.

  • The Polyp and the Medusa Life on the Move
    The Polyp and the Medusa Life on the Move Millions of years ago, unlikely pioneers sparked a revolution. Cnidarians set animal life in motion. So much of what we take for granted today began with Cnidarians. FROM SHAPE OF LIFE The Polyp and the Medusa Life on the Move Take a moment to follow these instructions: Raise your right hand in front of your eyes. Make a fist. Make the peace sign with your first and second fingers. Make a fist again. Open your hand. Read the next paragraph. What you just did was exhibit a trait we associate with all animals, a trait called, quite simply, movement. And not only did you just move your hand, but you moved it after passing the idea of movement through your brain and nerve cells to command the muscles in your hand to obey. To do this, your body needs muscles to move and nerves to transmit and coordinate movement, whether voluntary or involuntary. The bit of business involved in making fists and peace signs is pretty complex behavior, but it pales by comparison with the suites of thought and movement associated with throwing a curve ball, walking, swimming, dancing, breathing, landing an airplane, running down prey, or fleeing a predator. But whether by thought or instinct, you and all animals except sponges have the ability to move and to carry out complex sequences of movement called behavior. In fact, movement is such a basic part of being an animal that we tend to define animalness as having the ability to move and behave.

Tinea pedis is a very common fungal infection that affects a significantly large number of people globally. The presentation of tinea pedis can vary based on the different clinical forms of the condition. The symptoms of tinea pedis may range from asymptomatic, to mild- to-severe forms of pain, itchiness, difficulty walking and other debilitating symptoms. There is a range of precautionary measures available to prevent infection, and both oral and topical drugs can be used for treating tinea pedis. This article briefly highlights what athlete’s foot is, the different causes and how they present, the prevalence of the condition, the variety of diagnostic methods available, and the pharmacological and non-pharmacological management of the

Background • Animal model systems are a critical component of the process of discovery and development of new antifungal agents for treatment and prevention of invasive fungal diseases (IFDs). • Models of IFDs in murine, rat, guinea pigs, and rabbits have been developed and studied for development of new systemic antifungal agents. • We will review the conceptual, scientific, and regulatory framework for utilizing these models, cite specific examples of their application, and discuss their predictability for clinical trials. Objectives • Review role of laboratory animal model systems in development of new antifungal agents. • Assess the predictability of these models for predicting outcome in clinical trials.

Broad-range PCRs have been applied to identify fungal agents from pathology blocks, but sensitivity is variable. In this study, we compared the results of a specific Histoplasma qPCR (H. qPCR) with the results of a broad-range qPCR (28S qPCR) on formalin-fixed, paraffin-embedded (FFPE) tissue specimens from patients with proven fungal infections (n = 67), histologically suggestive of histoplasmosis (n = 36) and other mycoses (n = 31).

Considering the high burden of fungal diseases in Asian countries and its associated high morbidity and mortality (often exceeding 50%), we support the application of including major antifungal drugs against filamentous fungi, itraconazole and voriconazole in the list of WHO Essential Medicines (both available in oral formulation). The inclusion of these oral effective antifungal drugs in the essential list of medicines (EML) would help in increased availability of these agents in this part of the world and better prompt management of patients thereby reducing mortality. The widespread availability of these drugs would also stimulate more research to facilitate the development of better combination therapies.

  • Description of the Eukaryotic Animal Cell by Kayla Underwood General
    Description of the Eukaryotic Animal Cell By Kayla Underwood General Description The animal cell is the basic unit of life in the animal body. Cells are the building blocks of more complicated structures and they are specialized to carry out specialized functions. Cells are highly organized structures and in order to be successful in carrying out its functions they must be able to separate its contents from the external environment. Eukaryotic cell size is limited and it ranges from ten to one-hundred micrometers in diameter. The eukaryotic animal cell has a plasma membrane that surrounds the cell along with internal structures that are referred to as organelles. Organelles are specialized to carry out specific functions such as converting energy to usable forms, synthesizing compounds, and manufacturing structures that are essential to function and reproduction. Major Structures As figure 1 indicates, the major structures of the eukaryotic animal cell are the plasma membrane, the Golgi complex, the nucleus, which contains the nucleolus, a nuclear envelope, and nuclear pores, the endoplasmic reticulum (rough and smooth), lysosomes, mitochondria, peroxizomes, microfilaments, microtubules, cilia, and the centrioles. Each structure is described below. Figure 1: Anatomy of the Animal Cell Source: © 1995-2005 by Michael W. Davidson and the Florida State University. Retrieved May 4, 2005 from http://micro.magnet.fsu.edu/cells/animalcell.html Plasma Membrane A structure that surrounds all cells with the function of separating the cells contents from the outside environment. The plasma membrane serves as a selective barrier in that it only allows certain exchanges to take place between the internal area of the cell and the outside environment.
