Four Main Types of Junctions in Multicellular Organisms

- There are four main types of junctions in multicellular organisms, Anchoring Junctions, Occluding junctions, Channel-forming junctions and Signal-relaying junctions. Anchoring junctions include cell-to-cell adhesion and cell-to-matrix adhesions, and are bound to the cytoskeleton filaments inside of a cell. (Cadherin & integrin proteins) Cadherins bind with actin filaments to form adherens junctions and bind with intermediate filaments to form desmosomes, both of which are cell-to-cell adhesions....   [tags: anchoring, occluding, channel-forming]

Enzymes as Methods of Treatment for Human Conditions

- Practically all biological reactions are orchestrated by enzymes. Although there are a few nucleic acids as enzymes, typically they are globular proteins. The function of any enzyme is to act as a catalyst, lowering the energy of activation and increasing the rate of a reaction. Enzymes increase reaction rates by magnitudes of as much as trillions. Such extreme control over reaction rates gives enzymes the ability to decide which reactions will or will not occur. Because of this fact many drugs used for therapeutic purposes act by inhibiting enzyme activities; thus, some enzymes are actually drug targets, and can be seen as methods of treatment for conditions such as hypertension, inflamm...   [tags: hypertension, HIV, inflammation]

The Final Process in Inflammation: Wound Healing

- ... Macrophages are activated by endotoxins released by bacteria; cytokines such as interferon-γ (IFN-γ) secreted by sensitized T lymphocytes; mediators produced during acute inflammation and also extracellular matrix (ECM) proteins such as fibronectin.[1] Once macrophages are activated, it secretes a variety of biologically active products, for examples, reactive oxygen species (ROS), cytokines such as IL-1 and TNF, and arachidonic acid, at which may cause tissue injury and fibrosis if left unchecked.[1] • Lymphocytes: Lymphocytes, both T lymphocytes and B lymphocytes, migrate to the inflammatory site with the help of cytokines and adhesion molecules....   [tags: injury, leukocytes, blood]

Taking a Closer Look at Reaction Rate

- Reaction Rate is the measure of how quickly an organism’s neurons can communicate or react to a type of stimulus. In other words it is how fast an organism’s neurons can send signals to the brain and from the brain. The anatomy of a classic neuron is rather simple. A classic neuron comprises of a body and a tail. The body has a nucleus with arms protruding outwards, these are called dendrites. Dendrites are the postsynaptic neurons for synaptic communication, they receive neurotransmitters from the presynaptic neurons....   [tags: neuron reaction]

The Immune System And Complex Defence System

- The immune system is a highly evolved and complex defence system, armed against millions of potential pathogens that may cause infection at any point. Pattern recognition receptors, known as PRRs, are displayed by the cells of the innate immune system, such as macrophages and dendritic cells, and recognise pathogen associated molecular patterns or PAMPs. PAMPs are evolutionary conserved structural similarities found in many pathogens but not in the host’s own cells allowing the innate immune system to distinguish between self and non self and to react to the pathogens immediately (Mogensen, 2009)....   [tags: Immune system, Innate immune system]

The State Of Nature By John Hobbes

- It is uncontroversial to declare complete equality is a basic feature of most (if not all) accounts of the state of nature. Not only that, but that this complete equality is what the state of natural ultimately comes down to. Like Hobbes, Locke agrees with this point in his Second Treatise of Government: “To understand political power right, and derive it from its original, we must consider, what state all men are naturally in, and that is, a state of perfect freedom…” (2.8). Although Locke’s description of the state of nature won’t turn out to be as dire as Hobbes’, it rests on the same notion that humans are born equal in the state of nature....   [tags: Political philosophy, Government, Social contract]

Action Potential Self Propagates Along The Cell

- Action potential self-propagates along the cell, and creates a domino effect, stimulating other channels to open (Marieb & Hoehn, 2013, p.404). At a resting state, leak channels are the only channels that are open. Nevertheless, depolarisation occurs, meaning that the inside of the cell changes from negative to positive, only happens when other channels like voltage gated channel opens (Marieb & Hoehn, 2013, p.400).

Many enzymes require the presence of an additional molecule known as a non-protein cofactor. These include metal ions such as zinc and copper. Some cofactors are small organic molecules called coenzymes. The B-group vitamins Thiamine and Riboflavin are precursors of coenzymes.

Victrelis is the first drug in a new class of antiviral protease inhibitors. This drug binds to the Hepatitis C virus to prevent it from multiplying. The safety and effectiveness of Victrelis was evaluated in two phase III clinical trials with 1,500 adult patients. In both of these trials, two-thirds of the patients receiving Victrelis in combination with pegylated interferon and ribavirin experienced a significantly increased sustained virologic response, the hepatitis C virus was no longer detected in the bloo...   [tags: Using Victrelis]

Hutchinson Gilford Progeria Syndrome

- Hutchinson-Gilford Progeria Syndrome (HGPS) is a rare fatal genetic disease characterized by rapid aging in early life. It is caused by a recurrent de novo point mutation in Lamin A, where there is a change from glycine GGC to glycine GGT, in codon 608 of lamin A (LMNA) gene, within exon 11 (Eriksson et al., 2003). This mutation causes a truncated splicing mutant of lamin A, called progerin. The accumulation of progerin leads to various ageing-associated nuclear defects including disorganization of the nuclear lamina, disruption of nucleocytoplasmic transport, loss of heterochromatin, DNA damage with a loss of repair efficiency, and premature senescence (Liu, 2005)....   [tags: ]

The Causes of Hyperthyroidism

- The thyroid gland is found in the front of the neck and produces two main hormones. The hormones are called thuroxine (T4) and Triiodothyronine (T3). Together these hormones regulate the body’s metabolism by increasing energy use in cells, regulate growth and development, help to maintain body temperature and aid in oxygen consumption. These two hormones are regulated by hormones produced by the hypothalamus and pituitary gland. The hypothalamus senses changes in body’s metabolic rate and releases a hormone known as thyropin-releasing hormone (TRH)....   [tags: Anatomy, Thyroid Gland, Hormones]

In healthy people, infection will trigger an immune response via alveolar macrophages or dendritic cells. This leads to restriction of the pathogens to benign granulomas. Exposure to Cryptococcus neoformans leads to disease in immunocompromised patients and it can be fatal. Indeed, there is a high incidence of death in HIV patients who develop pneumonia and meningitis following infection....   [tags: lungs, degradative enzymes, drugs]

This process is regulated by the cells of an organism, it is very important to the survival of organisms at all levels. This is much more complex in eukaryotes than in prokaryotes. A major difference is the presence in eukaryotes of a nuclear membrane, which prevents the simultaneous transcription and translation that occurs in prokaryotes. Initiation of protein transcription is started by RNA polymerase. The activity of RNA polymerase is regulated by interaction with regulatory proteins; these proteins can act both positively, as activators, and negatively as repressors....   [tags: essays research papers]
