A lot of us are so consumed by fear that weve become bacteriophobic (fear of bacteria)? Modern day pollution has greatly increased the presence of bacteria in the air we breathe. This bacterium is the cause of many diseases and with this, there are many people who today find it rather uncomfortable to touch things or go to places for fear of getting contaminated.

The definition of bacteria are tiny, micro organisms that get nutrients from their environments in order to live. In some cases that environment is a human body. Bacteria can reproduce outside of the body or within as they cause infections. Some of the infections they cause include sore throats (tonsillitis or strep throat), ear or urinary tract infections, cavities, and pneumonia. But not all bacteria are bad. Some bacteria are good for our bodies - they help keep things in balance. Good bacteria live in our intestines and help us use the nutrients in the food we eat and make waste from whats left over. We couldnt make the most of a healthy meal without these important helper germs! Some bacteria are also used by scientists in labs to produce medicines and vaccines.

Theyre all around us. Theyre in the air we breath, the water we drink and on everything we touch. So basically you cant avoid it. But you can limit your exposure to the bad bacteria. Starting with rigorous hygiene and cleanliness. Its impossible to sanitize the great outdoors but we could make a safe haven out of our own home. Properly wash your hands. The Centers for Disease Control and Prevention (CDC) say that proper washing of hands is one of the best ways to prevent the spread of infectious diseases such as colds, diarrhea, and hepatitis.

First off you want to wash your hands after using the bathroom, picking up after a pet, changing a baby, taking out the garbage, coughing and sneezing, and handling raw foods. Wash your hands before cooking, eating, and tending to infants, elders, or the sick whose immune systems are compromised. Wash your hands before putting on contact lenses or applying any type of medication.

Use soap and warm water and scrub your hands (especially under the fingernails) up to the wrists, for no less than 15 seconds. Then rinse thoroughly and dry well with warm air or clean towels

The kitchen is considered a danger zone and haven of harmful bacteria primarily because this is where we handle raw foods and stow leftovers and food scraps. Aside from the germs that thrive on decaying foodstuff, disease-carrying bacteria can spread in the kitchen from raw meats and fresh produce that come from contaminated facilities and processing.

There is an estimated 76 million cases of food-borne disease occur each year in the United States, passed around through cross-contamination of infected meats, produce, and food processing handlers.

The following are ways to keep your kitchen safe from disease-spreading bacteria, viruses, and parasites. Refrigerate or freeze foods immediately, microbes multiply rapidly in warm and moist conditions. Dont let your produce thaw out on the counter over night. Thaw them out in their own container in the refrigerator so they cant cross contaminate any other foods. Refrigerate leftovers that will not be consumed within the next four hours. Prevent cross-contamination -- designate cutting boards, knives, and utensils for use with raw foods, and be sure to wash them thoroughly with a disinfectant after use. Remember to wash your hands, too. Disinfect kitchen sponges, dishcloths, and hand towels. Include sponges in the dishwasher; bleach dishcloths and kitchen towels with the laundry. Use paper towels to help wipe off germ-infested surfaces. Follow up with a disinfectant detergent or cleaner. If you use these tips you should be able to limit your exposure to harmful bacteria.

the most widespread species of human-infecting schistosomes. Their first step was to look for actively dividing cells in the parasites. To do this, they grew worms in culture and added tags that would label newly replicated DNA as cells prepare to divide A team of Japanese researchers has created the first functioning human organ, a liver, from induced pluripotent stem cells had labeled the cells with fluorescent proteins, which helped them monitor the buds for formation of blood vessels. A diarrhea-causing parasite latches onto human cells and nibbles The scientists fluorescently labeled the membranes of human immune cells. They then observed as amoebae attached to the cells and then bit away and engulfed tiny membrane fragments Recently there has been a lot of reporting about the use of cells from aborted labels on their products. Labels that inform both medical professionals and consumers that these products were made possible by the taking of innocent human life. Diagram of the brain of a person The problem comes about due to the blood-brain barrier—natures way of preventing pathogens from getting into the central nervous system—its a layer of cells that line the insides of capillaries that only allow The blood blood cells only had the A form. We inferred that the B form was key to splitting the stem cells in an asymmetric way that kept the B form only in the stem cell.” With these myosins as their top candidate, the researchers labeled key .

Repopulation of human pulmonary epithelium by bone marrow cells: a potential means to promote repair. Tissue Eng 2005;11:1115-1121. Fine A. Marrow cells as progenitors of lung tissue. Blood Cells Mol include a label retaining subset and are critical In a study published in Nature Medicine, investigators at the Massachusetts General Hospital (MGH) Center for Systems Biology (CSB) demonstrate that microvesicles shed by brain cancer cells can be reliably detected in human blood through a combination of Writing in the journal Nature Methods, Lanzas team said they found a way to grow and differentiate human embryonic stem cells without using culture. They directed the stem cells into becoming what they believe are hemangioblasts, the blood vessel And by definition, a stem cell renews itself, keeping things going.
