Titration of HPV-11 Infectivity and Antibody Neutralization Can Be Measured In Vitro

Titration of Rinderpest Virus and Its Neutralizing Antibody

Can Lignin Be Accurately Measured?

too simplistic (Sarkanen and Ludwig, 1971), and there are now many examples showing that other phenolics Forages serve an important role in providing nutrients to ruminants besides the cinnamyl alcohols can be incorporated into while providing positive benefits to the environment. Forage cell wall digestibility is incomplete because of several structural features within lignins (as reviewed by ...

Can Science and Technology Capacity be Measured?

The ability of a nation to participate in the global knowledge economy depends to some extent on its capacities in science and technology. In an effort to assess the capacity of different countries in science and technology, this article updates a classification scheme developed by RAND to measure science and technology capacity for 150 countries of the world.

Infectivity and neutralization of Cryptosporidium parvum sporozoites.

Cryptosporidiosis, a diarrheal disease of calves and humans caused by the coccidian parasite Cryptosporidium parvum, is terminated in hosts with normal immune systems. To assess the mechanisms of immunity in cryptosporidiosis, it is necessary to isolate and quantitate sporozoites, the infective stage of Cryptosporidium spp. Here we report the (i) separation of infective C. parvum oocysts from c...

In vitro HPV-11 infection of human foreskin.

Study of the infectious process of human papillomavirus type 11 (HPV-11) has been facilitated by the discovery that HPV-11-infected neonatal human foreskin epithelium can proliferate as xenografts into condyloma-like growths within athymic nude mice. Here we describe detection of HPV-11 infection of neonatal human foreskin-derived keratinocytes, infected and cultured entirely in vitro, by use o...
