Potato Hepatitis B Vaccine Succeeds in Human Trial
Genetically Modified Potatoes Prevent Hepatitis B (Sansi Science Report) American scientists have developed a genetically modified potato that may act as a hepatitis B vaccine, which is good news for developing countries. The hepatitis B virus attacks the liver and claims about 500,000 lives each year. But traditional vaccines require refrigeration, which is difficult to achieve in remote areas of warm developing countries. Medical workers often must also struggle to determine whether the expensive hepatitis B vaccine has been rendered ineffective by accidental heat exposure during transport. To this end, the University of Arizona

Feeding Livestock with Fresh Wheat Bran Requires Vigilance Against Stomatitis
Many breeders are accustomed to feeding fresh wheat bran directly to livestock, and untreated fresh wheat bran often punctures the oral mucosa of livestock and causes stomatitis. After livestock develop stomatitis, they want to eat but refuse food; they take feed into their mouths but dare not chew, or after chewing a few bites they spit the feed back out; white turbid mucus continuously flows from the mouth; and wheat awns can be seen stuck all over the tooth roots and the base of the tongue in the oral cavity. Once this disease occurs, first clean the wheat awns from the livestock's oral cavity thoroughly, then rinse the oral cavity with clean water to prevent infection. Then
