The effect of the tus protein-terB sequence complex of Escherichia coli on the movement of the SV40 large tumor antigen (T antigen)-mediated replication fork during SV40 DNA replication in vitro has been examined. In the monopolymerase and dipolymerase systems, the tus protein-terB complex efficiently blocked the replication fork movement in a polar fashion, as observed in prokaryotic replicati...

Background Cervical cancer caused by human papilloma virus (HPV), is the second most common cancer for women. This cancer is distributed worldwide, with ~80% of cases are found in the developing countries. In Indonesia, data of HPV genotypes are still limited and do not represent all regions of the country. Thus, here we report genotyping of HPV samples collected from the Dr. Soetomo Hospital S...

We analyzed the alteration of the hst-1 and int-2 genes in 36 cases of esophageal squamous cell carcinoma, 42 cases of gastric adenocarcinoma, and 52 cases of colorectal adenocarcinoma. Coamplification of the hst-1 and int-2 genes was observed in 19 of 36 esophageal carcinomas (52%), 16 of 34 primary tumor tissues (47%), and 10 of 10 metastatic tumors (100%). The degree of amplification ranged ...

Two facts make it important to determine whether the proportion of ribosomal R N A (rRNA) 1 genes in salivary glands of Rhynchoscza~a angelae varies throughout the end of the last (fourth) instar of larval development, namely: (a) In this instar, during the appearance of " D N A puffs," it is possible to observe many micronucleoli around the chromosomes (1). Perhaps the micronucleoli maybe ascr...

Abstract Objective The present study examines the bidirectional nature of associations between parenthood and mental well-being using 36-year longitudinal data. Background Mental can affect if when one becomes a parent (selection hypothesis), characteristics (causation hypothesis). However, life course research has infrequently studied these hypotheses in parallel. Previous studies have also ty...
