Motivated by the Strominger-Yau-Zaslow conjecture, we study fibre spaces whose total space has trivial canonical bundle. Especially, we are interest in CalabiYau varieties with fibre structures. In this paper, we only consider semi-stable families. We use Hodge theory and the generalized Donaldson-Simpson-Uhlenbeck-Yau correspondence to study the parabolic structure of higher direct images over...

Sensitive immunologic techniques and more purified preparations of bovine pituitary thyrotropin have made it possible to re-examine the question of whether thyrotropin acts as an antigen upon injection into heterologous species. This possibility was first indicated by Werner (1, 2) in 1936, to explain the loss of responsiveness to thyrotropin which Collip and Anderson (3) previously had observe...

Abstract Background The hemagglutinin-neuraminidase (HN) protein of Newcastle disease virus (NDV) is a major antigen that can induce protective antibodies in poultry. However, its antigenic epitopes have not been fully elucidated. Therefore, defining the linear HN, especially neutralizing epitopes, will be useful for revealing characterization. Methods In this study, we analyzed B-cell immunodo...

Antisera were prepared against cytochromes c3 from Desulfovibrio africanus, D. vulgaris, and D. salexigens. Cross-reactions were observed between antisera to D. vulgaris and D. africanus cytochromes and heterologous cytochromes c3. A weak cross-reaction with antisera against both D. vulgaris and D. africanus cytochromes and the acid form of the D. salexigens cytochrome was seen; the basic form ...

Antisera to the Rous sarcoma virus transforming protein pp60src were produced in rabbits immunized with p60src purified from recombinant Escherichia coli. Immunization with isolated V8 proteolytic fragments of p60src resulted in antisera specific for the amino- and carboxy-terminal domains. The reactions of these antisera with pp60v-src and the normal cell protein p60c-src were characterized.

B-cell peptide epitopes in chlamydial heat shock protein 60 (hsp60) were elucidated with antisera from 13 rabbits immunized with Chlamydia trachomatis serovars B, C, and L2 and antisera from eight women with C. trachomatis-associated ectopic pregnancies. Thirteen major epitopes were identified with the human sera, 10 of which were also observed with rabbit antisera. Seven of the 13 epitopes rec...
