There are different types of bacteria that can be divided into harmful bacteria and helpful bacteria. Some helpful bacteria are as follows;

Fermentation is necessary to taste cheese or yogurt. Helpful bacteria like brevibacterium give carbon dioxide during the process of fermentation. Helpful bacteria are responsible for the complexity and acidity in beer.

Pseudomonas Syringae is a type of bacterium found in leaves and grass and produces protein for frost formation. Now the protein from this type of bacterium is sold in a brand name to enhance the formation of snow.

Caulobacter Crescentus is another helpful bacterium which has long sticky sugar molecules. They are better than glues and therefore natural and non toxic adhesive are made from these bacteria.

There are billion types of bacteria around us. Most of them are helpful bacteria and they are very important for our survival. Yet there are some few harmful bacteria that cause diseases.

Harmful types of bacteria are as follows;

Streptococcus bacteria are one of the harmful bacteria that may cause disease in human and animals particularly mammals. They cause some small infections like strep throat and some dreadful diseases like pneumonia. Some harmful streptococci may even cause death. These bacteria are highly contagious and can spread easily through air.

Group A and B bacteria are more harmful streptococcus bacteria than any other bacteria strain. They may cause scarlet fever, rheumatic fever etc. They may also cause problems in female reproductive system. However they are controllable through vaccines and antibiotics.

Yet there are some harmful bacteria ha may cause gum bleeding and other teeth problems. As they progress rapidly, steps must be taken to prevent them in the early stage itself. However there are some harmful bacteria that are highly resistant to drugs.

Bacteria can be classified into 3 types based on the shape. The rod shaped bacteria, Sphere shaped bacteria and Spiral bacteria are the three types of bacteria. There are some bacteria that are in different shapes and so it is difficult to classify tem according to shape.

Some bacteria require oxygen for their survival while others do not. On the basis of oxygen requirement they are classified as aerobic and anaerobic bacteria.

On the basis of Gram staining method bacteria are classified into two types. They are Gram positive bacteria and Gram negative bacteria. Bacteria are also classified according to their growth and reproduction. Such classification includes Autotrophic bacteria and heterotrophic bacteria. Autotrophic bacteria take the required carbon from carbon dioxide by itself. Some types of autotrophs will use sunlight to transform carbon dioxide to sugar. While heterotrophic bacteria will take sugar or carbon from the environment they live.

Scientists have classified various types of bacteria according to the phyla. Each phylum then again corresponds to various species of bacteria. The bacteria can be classified according o the environment they live also. Sweet water bacteria, ocean water bacteria are some of the types of bacteria classified according to their environment. Some types of bacteria can survive in extremely hot or cold temperature.

Consumers should be wary about unseen dangers in everyday groceries as stated by the consumer reports, and bacteria contamination is only the beginning. Consumer reports finds suggests that many dangerous ingredients, such as sodium nitrite, are intentionally added by meat processors. Richard of the National Chicken Council said that the Consumer Report figures were greatly exaggerated and Richard Raymond of the U.S. Department of Agriculture said the sample size was too small. That’s 500 samples out of 9 billion chickens slaughtered a year, he said. He added that the report showed a salmonella rate of 15 percent, which jibes with USDA figures for 2005 showing a rate of 16.3 percent. However, 81 percent of the chickens tested by Consumer Reports had campylobacter infections, up from a 2003 test that found the bacteria in 42 percent of the test sample. Currently, the USDA does not test for campylobacter, he said they were testing an alternative protocol.

Consumer reports find that most designs can be folded into the compact shape of a golf bag and slipped into a zippered carrying case for travel or storage. The frame is made of metal tubing, and the sides are mesh or moisture-resistant fabric. Because they are rectangular, they fit through most doorways. Consumer reports have said that Playpens, which play yards have largely supplanted, are square. A play yard’s top rails are typically hinged at the center so they can be folded. Many play yards sold in the 1990s had rails that could collapse at the hinges, forming a steep, V-shaped angle that put babies at risk of entrapment or strangulation. Fourteen children have been killed when play yards collapsed, according to the Consumer Reports Commission. To address the hazard, the industry’s voluntary standard, updated in 1999 and again in 2002, requires that hinges automatically lock when rails are pulled up. Two more requirements have now addressed the collapse issue. First, any unit that folds must have a latch, lock, or other device that will prevent the Play yards from unintentionally folding as long as it is set up according to the manufacturer’s recommendations. The second requirement is that no top rail can appear to be in proper position unless the locking device is fully engaged. As a result of the new requirements, a Play yards can only be used if the top rail and any hinges are safely engaged in a locked position, making the play yard safe from unintentional collapse. The plastic must undergo a testing before getting into the market.

Introduction

David Morgan, a surgeon at the hospital, says the idea of sniffing out super bugs came to him one day in the operating theatre. ‘I was operating on neck abscesses on two different patients and noticed their infections had slightly different smells, so I wondered if a machine could work out what the bacterial infections were from the smell alone.’ So it was possible to make electronic nose to recognize many diseases for cure.  

Application Areas

1. Break-through on TB by E-nose

 The lives of more than one million people could be saved, thanks to the pioneering work of researcher that recognize the electronic nose that  has found a way of diagnosing TB by smelling breath. And he estimates the electronic nose will save 60 per cent of the two million people in the world who die from the disease every year. … The machine, which costs between 5,000 and 10,000 and which is being tested in Latvia and India, uses artificial intelligence to identify the TB smell. Readout gives a probability of whether a patient has the disease.

2.  A Electronic nose sniffs out TB.The scientists at Cranfield took ideas used by makers of food flavorings, among others, to create sensors that can recognize smells. The sensors use artificial intelligence to identify bacteria in TB cases, as well as other respiratory diseases. The technique analyses sputum – saliva and mucus – converted into gas form.

3. Electronic noses and tongues in food analysis. The applications of electronic noses and tongues in food analysis. A brief history of the development of sensors is included and this is illustrated by descriptions of the different types of sensors utilized in these devices. As pattern recognition techniques are widely used to analyse the data obtained from these multi-sensor arrays, a discussion of principal components analysis and artificial neural networks is essential.

4. Wine-tasting robot to spot fraudulent bottles.A robotic wine taster, capable of distinguishing between 30 different varieties or blends of grape, has been developed by engineers in Japan. The idea is to automate wine analysis so that retailers and customs officials can easily check that a wine is indeed what its label declares.

Treatment of hypertension included nonmedical and medical treatment. If we not give attention about our blood pressure and blood pressure to high in every day it leaded to more danger diseases.

Three main organs effected from hypertension.

Brains

Stroke is first serious conditions flowing from hypertension. Who have severe hyper tension in long time or sudden shoot blood pressure. Especially systolic blood pressure more than 200 mmHg Or diastolic blood pressure more than 120 mmHg they are lead to rupture of arteries in the brain. The blood clot from bleeding compression our brain and make paralysis.

Kidney

Kidney is important because of it is main eradicate waste products in body. If kidney can not work body waste products are pooling in our bodies then bad effect from waste products present.

Heart

Hypertension can result in hardening and thickening of the arteries. This effected directly to heart vessels it can ischemic heart diseases and more heart diseases.

Shower Head Bacteria and Disease – Your Shower Head May Make You Sick

A recent study by Norman R. Pace of the University of Colorado found that a bacterial organism, a relative of the bacteria that causes tuberculosis, called Mycobacterium, may be ready to shower down on you every time you get under it.

The study indicated that over the years this buidup of dangerous bacteria in your shower head may be making you sick. Because the shower head aerosolized the bacteria into the air, it is recommended you turn the shower on and leave the room for a minute.

The bacteria will still be in the air but at least will not rain down on you. The first spray of the shower is suppose to be the worse. Anyone with breathing problems should replace their shower head as soon as possible according to the study.

The study claims that people who get water from municipals city water supplies were much more prone to have a heavier build up of Mycobacterium in their shower heads. People who got their water from wells had considerably less buildup or this dangerous bacteria in their shower head.

The study also claims that shower heads should be changed 2 to 4 times a year depending on what water supply you are using.

This report is definitely worth reading!

Autism And Nutrition

With autism among children rising to astounding rates of 1 in 150 children worldwide, it is the fastest growing childhood epidemic of our time. The number of children affected by this whole-body disorder is expected to rise even further over the next decade. According to research reports, more children will be diagnosed with autism this year than cancer, diabetes, Downs Syndrome and AIDS combined. Approximately 1 million individuals in the United States have autism—as of today, there is no known cause and no known cure.

You know the statistics. You are keenly aware of how interesting your path has become-a life you didn’t exactly imagine you would be in. You see the autism awareness ad campaigns on television. You hear a new president dedicate himself to helping children with autism through research dollars and insurance coverage requirements. You are connected to your local autism support group. You participate in lively debate over genetics, vaccines, ABA therapy and a new topic-biomedical intervention and autism diets.

Determining the breast cancer stages is important since it enables the patient and doctor to identify the treatment necessary for one’s condition. Also, it is essential in assessing the risk of the given condition and what lifestyle changes the patient can do to improve their health.

Identifying A Breast Cancer’s Stage

When talking about breast cancer stages, it is aimed at describing the extent of the cancer in the body. So, if you ask how a breast cancer is staged, doctors often start to classify whether it is invasive or non-invasive. Other factors considered are the tumor size, number of nymph modes involved, and what other parts of the body it has managed to affect.

Determining a cancer’s stage is helpful during prognosis and deciding on a treatment option.

To determine the stage, a few standard procedures are done by the doctor on a patient. They undergo physical exam and biopsy to acquire the data needed by the doctor for the diagnosis.

If needed, further tests are also conducted such as imaging tests that include x-ray, bone scans, mammograms for the breasts, CT scans, positron emission tomography (PET), and magentic resonance imaging.

What Are the Breast Cancer Stages?

Now that the importance of determining the different breast cancer stages have been clarified, as well as the methods used to identify them, it is now time to move on to discussing each of the stages. Take note of the features and extent of the cancer in each of the stages:

Breast Cancer Stage 0

This stage renders the case of breast cancer to be non-invasive. At this point of the breast cancer, cancer or non-cancerous cells cannot be detected yet.

The abnormal cells are still at the stage wherein they try to spread out within the specific part of the breast where the cells are rooted. Also, they can try to expand on the neighboring tissues as the cancerous cells continue to grow.

Breast Cancer Stage I

Once the breast cancer enters this stage, it is now categorized as an invasive type of breast cancer. Meaning, the cancer cells have now worked their way towards the neighboring tissues. Stage I breast cancer also exhibit the following characteristics:

•    The cancerous tumor has reached the size of 2 centimeters.
•    No lymph modes are affected.

Breast Cancer Stage II

For this particular stage of breast cancer, it is also known as an invasive type of cancer and is broken down into two more categories:

1) Stage IIA

Even in this particular stage, the conditions can be different:

•    A tumor does not exist in the breast but cancerous cells are detected in the lymph nodes.
•    A tumor could exist but measures less than 2 centimeters;
•    The tumor has expanded beyond 2 centimeters but less than 5 centimeters without reaching the lymph nodes.

2) Stage IIB

This invasive level of the cancer are recognized as either one of the following:

•    The tumor exceeds 2 centimeters in size but less than 5 centimeters, while also reaching the lymph nodes.
•    The tumor is more than 5 centimeters in size but has not yet reached the axillary lymph nodes.

Breast Cancer Stage III

1) Stage IIIA

In this stage, the tumor could either be detected or not. Aside from the axillary lymph nodes, cancer can also stick to other structures outside of the lymph nodes and become clumped together.

2) Stage IIIB

In this stage, the tumor can grow in size and affect other areas of the body outside of the actual breast, whether th chest wall or skin of the breast. This is the stage wherein inflammatory breast cancer takes place.

3) Stage IIIC

In some cases, sign of breast cancer might not be detectable yet. However, the tumor could already be spreading towards the breast skin, chest wall, and below your collarbone.

Breast Cancer Stage IV

In this level, the cancerous cells have managed to spread to various organs of the body. Therefore, the cancer is no longer restricted on the breast and lymph nodes, which signifies the initial diagnosis of breast cancer. The reason why diagnosis is done only during this stage is because cancerous cells were not detected while still within the breast.

Recognizing breast cancer stages does more than just identifying treatment options, but also enables doctors and patients to understand the developmental pattern of the disease.

Using known risk factors for breast cancer, mathematical models can be developed to help answer important questions.  These mathematical models are useful tools for researchers and for patients as follows:

• 1. Research on risk factors – The Claus risk assessment model was used to discover the subpopulation of people who had an autosomal dominant genetic allele that increased their risk from 10% to 92%. This led to the discovery of the BRCA genes associated with breast, ovarian, and prostate cancer.
• 2. Clinical trial eligibility – The Gail risk assessment model was developed to help researchers determine who to enroll in the NSAPB Breast Cancer Prevention Trials

where chemoprevention was shown to reduce breast cancer risk.

• 3. Guidelines for doing BRCA testing – BRCA testing is very expensive and practically worthless if done on everyone (because it is so rare to be homozygous for BRCA1 or BRCA2). Mathematical models such as the BRCAPRO, BOADICEA, and Tyrer-Cuzick models can help determine what patients should undergo BRCA testing. The decision for testing is usually made when one of these models predicts a 10% or greater chance that there is a mutation of the BRCA1, BRCA2, or both genes.
• 4. Guidelines for doing MRI screening for breast cancer - MRI screening for breast cancer is not a cost effective screening test for the general population, but in specific groups, there are clear cut reasons to do so. In general, screening MRI is recommended for women with 20-25% or greater lifetime risk of breast cancer. The BRCAPRO and Tyrer-Cuzick models have been used to help make clinical decisions about ordering MRIs for breast cancer screening.
• 5. Guidelines for breast cancer therapy - The Gail model is used clinically to help

determine who should be put on tamoxifen or raloxifene for chemoprevention.  Other models have been used to help make decisions about breast cancer risk reduction with prophylactic mastectomy.

For these reasons, it is important to understand these models.  These models are collectively refered to as “risk assessment tools”.  The following paragraphs summarize the most popular and most widely used risk assessment tools.  Keep in mind that none of these risk assessment tools apply to breast cancer survivors.  No mathematical model has been widely accepted to determine cancer risk in cancer survivors. 

General Risk Assessment Tools

Gail Model:  The Gail model is a validated risk-assessment model that focuses primarily on nonhereditary risk factors, with limited information on family history.  It was developed by scientists at the National Cancer Institute and the National Surgical Adjuvant Breast and Bowel Project (NSABP) to assist health care providers in discussing breast cancer risk to determine their eligibility for the Breast Cancer Prevention Trial.  The tool allows one to project a woman’s individual estimate of breast cancer risk over a five-year period of time and over her lifetime.  It also compares the woman’s risk calculation with the average risk for a woman of the same age.  The Gail Model is an on-line quiz that has 13 questions and is interactive.  This calculator is based on published risk statistics and methods gathered from peer-reviewed journals, and has been extensively tested for its validity. 

The major limitation of the Gail model is the inclusion of only first-degree relatives, which results in underestimating risk in the 50% of families with cancer in the paternal lineage and also takes no account of the age of onset of breast cancer.  It may underestimate risk in certain groups, such as obese patients.

National Cancer Institute Model:  The NCI risk assessment tool is essentially a simplified Gail Model that also factors in race.  Race is a factor in determining breast cancer risk but is excluded when determining eligibility for clinical trials.  This tool is probably the most popular risk assessment tool available to the public as an on-line, interactive risk calculator.  The on-line quiz is a shorter, nine-point questionnaire that includes multiple factors, giving a woman her future five-year risk of breast cancer and her lifetime risk of breast cancer.

The NCI tool does not account for a lot of risk factors that can be modified.  For this reason, it is difficult to use this test as a motivation tool to show people how lifestyle can alter their risk of breast cancer.  It also cannot be used in breast cancer survivors, in patients with DCIS, LCIS, or people who carry one of the BRCA genes.

BRCAPRO model:  This is a statistical model available as a computer program that uses two different algorithms to evaluate family history and helps a doctor determine the likelihood of finding either a BRCA1 mutation or a BRCA2 mutation in a family.  The results of this can be used to determine if BRCA testing is indicated.  This is very useful in light of the high cost of BRCA testing ($3,000).  None of the nonhereditary risk factors can yet be incorporated into the model, however.  In a comparison of four different methods for estimating breast cancer risk in patients with a family history of breast cancer, the BRCAPRO model was the least accurate.  It predicted only 49% of the breast cancers that actually occurred in the screened group of patients with a family history of breast cancer.

Harvard Center for Cancer Prevention Risk Assessment Tool:  This is another breast cancer risk assessment tool that includes more lifestyle factors than the NCI or Gail Model tools.  It has not been studied as extensively as the Gail Model or the simplified NCI model, but it is promising in that it includes many lifestyle factors that people can do to modify their risk of developing cancer.  It is also an on-line questionnaire that can be used by both women and men to estimate their breast cancer risk.

Making all this practical

          Now after a thorough and confusing discussion of all these statistical models, it’s time to make all this information practical.  What is the best way to help a patient accurately assess her risk of breast cancer and if possible, show her what positive factors are reducing her risk and what negative factors can be changed to reduce her risk?  If possible, it would also be great to show the patient the value and indications for testing, imaging, chemoprevention, and in some cases surgery.  A discussion of the practical aspect of each of these is addressed in a Q & A format below:

Q: What (free) online programs can be used to help a patient assess their risk of breast cancer?

A: Several of the risk assessment tools mentioned above can be accessed for free by the public. Here are the tests and their websites:

• 1. Your Disease Risk – English version: http://www.diseaseriskindex.harvard.edu

This is a great interactive questionnaire that calculates five-year and lifetime risk of breast cancer developed by the Harvard Center for Cancer Prevention and made public online in 2000.  In 2005, they launched the Spanish version of the site, “Cuidar de su Salud”.  The risk calculator includes lifestyle factors such as weight, dietary vegetables, alcohol intake, as well as Jewish ethnicity.  It does not include other ethnicities, however, and is not accurate for BRCA mutation carriers or breast cancer survivors.  Despite these issues, this is by far the best free online risk calculator since it is very interactive and gives you a personalized description of your risk in the form of a colored bar graph, which they can electronically manipulate to experience “virtual” risk reduction.  The bar graph is a seven-level scale that compares users to a typical man or woman your age.  Users learn where to focus their prevention efforts and how to make lifestyle changes by “clicking on” personalized strategies.  With each click, the bar graph shrinks, and the user watches his/her predicted risk drop.  This is a great concept to motivate people to participate and comply with lifestyle modification measures.

• 2. The NCI Risk Assessment Tool -regular web: http://www.cancer.gov/bcrisktool

     This is the easy to use, on-line questionnaire based on a modified Gail model that also includes ethnicity.  It does not factor in a personal history of breast cancer, DCIS, or LCIS.  It does not account for other factors such as BRCA status, hormonal replacement therapy, lifestyle factors, breast feeding, menopause, or mammographic density.  Despite these issues, it is a very useful tool that gives a woman her five-year and lifetime risk of breast cancer.  It is the only risk assessment tool that can be used via mobile handheld devices (any type).  A version of this can be downloaded for PDAs with Windows Pocket PC operating system as well.

Q:  What programs can be used to help a doctor make decisions about ordering a breast MRI?

A:  The American Cancer Society has developed some very good guidelines for breast cancer screening with MRI.  It should be emphasized that MRI is an adjunct to mammography, not a replacement.

Breast cancer type

Breast cancer type is categorized by whether it begins in the ducts or lobules, the organs responsible for breast milk production. Medullary carcinoma accounts for 15% of all breast cancer types.

Media Relations Contacts Online Press Kit Rumors, Myths, and Truths Glossary About the American Cancer Society Breastfeeding, Other Factors May Affect Risk of Breast Cancer TypeAtlanta 2008/08/25 -Factors such as age at menopause as well as a woman?s breastfeeding practices can influence her risk of developing certain types of breast cancer.

The investigators found that reproductive risk factors varied considerably by breast cancer subtype. Their analysis included 1,023 women with breast cancer whose cells express the estrogen and progesterone receptors (called luminal cancers), 39 women with HER2-overexpressing breast cancer, and 78 triple-negative cases (no expression of estrogen, progesterone, or HER2 receptors). The study also included 1,476 women without breast cancer. ? They added that additional studies on the causes of breast cancer subtypes are needed to better understand the biology of the disease. Learn more about our commitment to providing complete, accurate, and private breast cancer information. The study?s results suggest that there are distinct and separate hormonal risk factors associated with different subtypes of breast cancer. Women with what is referred to as "triple-negative" breast cancer are more likely than other women with breast cancer to experience a relapse, a new study by Canadian researchers shows. Despite having a high risk of early recurrence, the study indicates that triple-negative breast cancer patients who remain disease-free for eight years are unlikely to die of breast cancer and may be "cured" of their disease.

Breast Feeding Will Lowers Risk Of Breast Cancer

Breastfeeding for 6 months or longer was associated with a lower risk of luminal cancer as well as triple-negative cancer, a type that can be particularly aggressive and difficult to treat. Understanding the specific type of breast cancer can help you ask better questions and work with your physicians to get the best breast cancer treatments. For more information on the types and stages of breast cancer, watch Beyond the Shock®. Medullary carcinoma accounts for 15% of all breast cancer types. Infiltrating lobular carcinoma is a type of breast cancer that usually appears as a subtle thickening in the upper-outer quadrant of the breast. Making up about 2% of all breast cancer diagnosis, tubular carcinoma cells have a distinctive tubular structure when viewed under a microscope. Typically this type of breast cancer is found in women aged 50 and above. Inflammatory breast cancer is a rare and very aggressive type of breast cancer that causes the lymph vessels in the skin of the breast to become blocked.

Breast Cancer Risk

The study’s results suggest that there are distinct and separate hormonal risk factors associated with different subtypes of breast cancer. Amanda Phipps, a predoctoral research associate at the Fred Hutchinson Cancer Research Center in Seattle, and her colleagues conducted a study to better understand the specific risk factors for the subtypes of breast cancer, which are classified by expression of the estrogen receptor, the progesterone receptor, and the HER2 receptor. The investigators found that reproductive risk factors varied considerably by breast cancer subtype. Breastfeeding for 6 months or longer was associated with a lower risk of luminal cancer as well as triple-negative cancer, a type that can be particularly aggressive and difficult to treat. Both late age at menopause and use of estrogen plus progestin hormone therapy were associated with an increased risk of luminal disease. Finally, no differences in risks associated with number of children or the age when a woman first gave birth were observed by subtype. The study authors concluded that their results indicate that "certain reproductive factors may have a greater impact on risk of certain molecular subtypes of disease compared to others. Despite having a high risk of early recurrence, the study indicates that triple-negative breast cancer patients who remain disease-free for eight years are unlikely to die of breast cancer and may be "cured" of their disease. Insulin resistance, hyperinsulinemia, and changes in the signaling of growth hormones and steroid hormones associated with diabetes may affect the risk of breast cancer. Despite many proposed potential pathways, the mechanisms underlying an association between diabetes and breast cancer risk remain unclear, particularly because the 2 diseases share several risk factors, including obesity, a sedentary lifestyle, and possibly intake of saturated fat and refined carbohydrates, that may confound this association. Although the metabolic syndrome is closely related to diabetes and embraces additional components that might influence breast cancer risk, the role of the metabolic syndrome in breast carcinogenesis has not been studied and thus remains unknown.
