Japanese researchers have developed a prototype miniature robot that can be inserted through an incision and used to perform medical procedures deep inside the body. The beetle-shaped robot,which weighs five grammes and measures two centimetres in length and one in diamter, is the result of three years of work by researchers from Ritsumeikan University and its partners. The tiny robot incorporates various medical devices including a small camera, sensors and a drug delivery injector, which could reduce the need for surgery. Data is sent to a computer through a slim cable although researchers hope to develop a transmitter.
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 ...
