| evidence that pyrimidine dimers in dna can give rise to tumors. | the amazon molly, poecilia formosa, is a small fish that grows in clones. hence, cells from one animal may be transplanted to another without danger of rejection. cells from thyroid and adjacent tissue were irradiated with uv light in vitro and injected into the abdominal cavity of isogeneic recipients. at appropriate uv doses and numbers of cells injected, all recipients showed exuberant thyroid proliferation. we give arguments and data indicating that the proliferation is a tumor, not a goitro ... | 1977 | 271984 |

| function of cloned t4 recombination genes, uvsx and uvsy, in cells of escherichia coli. | genes uvsx and uvsy of bacteriophage t4 both control genetic recombination and repair of damaged dna, and their mutant phenotypes bear a striking resemblance to each other. it has been shown recently that the uvsx gene product is analogous to the reca gene product of escherichia coli (yonesaki et al. 1985; yonesaki and minagawa 1985; formosa and alberts 1986), but the function of the uvsy gene is unknown. to obtain further insight into the function of these genes we introduced plasmidborne copie ... | 1988 | 3280947 |

| nucleotide sequence of the histone gene cluster in the coral acropora formosa (cnidaria; scleractinia): features of histone gene structure and organization are common to diploblastic and triploblastic metazoans. | we report the nucleotide sequence of the core histone gene cluster from the cnidarian acropora formosa. this is the first histone gene cluster to be sequenced from a diploblastic organism and the predicted amino acid sequences most resemble those of sea urchin equivalents. each of the cnidarian histone genes has two conserved regions 3' of the coding sequences and these closely resemble those of the metazoan alpha-class histone genes. in a. formosa the core histone genes are arranged as opposed ... | 1993 | 7901422 |
| [epidemiology of the plague. changes in the concept in research of infection chains since the discovery of the plague pathogen in 1894]. | three major plague epidemics have been recorded worldwide up to this day: the justinian plague in the 6th century, the black death in the 14th century and the recent 20th century pandemic. the latter occurred at a time of advanced microbiological knowledge which permitted the etiology and the modes of transmission and spread of this bacterial infectious disease to be clarified. the present thesis is an attempt to describe the changes in plague research that occurred during that period of time. w ... | 1993 | 8142341 |
