Solution of sea food allergy

Chinese researchers have taken a step towards removing a protein from prawns that cause an allergic response, without resorting to genetic manipulation. Li Zhenxing led the research at the Ocean University of China.The team revealed that treating prawns with a combination of heat and irradiation significantly reduced the level of reactive proteins called allergens. They took blood from patients with shrimp allergies, added samples of treated and untreated prawn, and measured how antiboides in the blood reacted. They found that levels of "Pen a 1" , one of the major allergens, decreased 20-fold after treatment.Zhenxing's team suggests that irradiation damages the proteins, revealing hidden reactive amino acid residues. Subsequent heating then destroyes the exposed residues. "Radiation and heat seems to be a promising method for reducing the immunoreactivity" said the researchers.

Causes of canine alopecia

Causes Parasites External parasites are notorious for causing alopecia in dogs. Ticks, lice, fleas and mites can all cause intense itching and scratching, which leads to hair loss. Mange (a skin disease) may also cause localised to generalised hair loss. Fungal infections Fungal infections of the skin (called ('Dermatophytosis') can cause partial to complete alopecia with scaling and redness. Some fungal infections are zoonotic, which means that they have the potential to cause skin lesions in people as well. Bacterial infections Bacterial skin infections can cause alopecia with redness, skin crusting and circular patterns of hair loss. Bacterial folliculitis is the most common cause of multi focal alopecia. Allergies Allergic pets have itchy skin, and in response they scratch or chew out their hair. Pets can be allergic to: 1. Foods- Grains (wheat, soy, corn, pork, meat, fish, milk, yeast. 2. Contact allergies- Walking through grass, chemically treated floors or ...

WHAT YOU CAN DO : There are several things you can do to lower your blood pressure. 1) Eat a healthful diet : Excessive sodium intake also has been linked to an increased risk of high blood pressure. Limiting salt intake to 2,000 milligrams per day may help keep blood pressure low. A diet of 1,500 milligrams or less salt is especially effective at controlling blood pressure. Sodium is found in many foods, so keep an eye on the ingredients list to help rein in your sodium intake. In addition, avoid adding table salt to foods. 2) Avoid smoking and excessive drinking : The nicotine found in tobacco products constricts blood vessels, causing your hear to beat faster and raisi...
