Question Answering (QA) aims at identifying answers to users’ natural language questions. A QA system can release the users from digesting large amount of text in order to locate particular facts or numbers. The research has drawn great attention from several disciplines such as information retrieval, information extraction, natural language processing, and artificial intelligence. TREC QA trac...

The effects of some factors on the preparation and regeneration of protoplasts from the taxol-producing fungus Nodulisporium sylviforme were discussed in this paper, including combination of various enzymes, digesting time and temperature, and pH value, osmotic stabilizers, pretreation, culture medium and culture method. Under the condition of the mixed enzymes in osmotic pressure stabilizer (0...

The cooking of food is hypothesized to have played a major role in human evolution partly by providing an increase in net energy gain. For meat, cooking compromises the structural integrity of the tissue by gelatinizing the collagen. Hence, cooked meat should take less effort to digest compared to raw meat. Likewise, less energy would be expended digesting ground meat compared to intact meat. W...

PURPOSE Keratoconus is characterized by thinning and scarring of the central region of the cornea. Previous research showed that, in corneas obtained from patients with keratoconus, lysosomal enzyme activities are elevated, whereas levels of protease inhibitors such as alpha1-proteinase inhibitor are reduced. This study was undertaken to examine further the expression of a spectrum of proteolyt...

1. An extracellular, proteolytic enzyme has been observed in more than 30 strains of beta type, aerobic and facultative hemolytic streptococci. 2. The enzyme is readily demonstrable in sterile filtrates of cooked meat cultures. 3. No gas or foul odor is produced. 4. It is partially inactivated by exposure to about 60 degrees C. for 45 minutes or longer. 5. The enzyme manifests itself in cooked ...

Matrix metalloproteinases (MMPs) are involved in the pathophysiology of several central nervous system diseases that share common pathogeneses, such as disruption of the blood-brain barrier (BBB), neuroinflammation, oxidative stress, and remodeling of the extracellular matrix (ECM). In early ischemic injury, MMPs participate in disruption of the BBB by digesting the basal lamina of capillaries ...
