1. Estudo da proteína de choque térmico GRP78 para o desenvolvimento de um sistema de receptor-ligante para o câncer de próstata / Use of the heat-shock protein GRP78 for the development of a receptor-ligand system in prostate cancer
Introduction: Despite the advances in diagnosis and treatment, advanced prostate cancer remains a lethal condition. Improved methods of therapy are needed to reduce the morbidity and mortality rates associated with this disease. The Glucose-regulated protein-78 (GRP78), a stress-responsive heat-shock protein involved in antigen presentation, was recently des

2. Replication of RNA bacteriophages in the presence of rifamycin.
Replication of RNA bacteriophages in the presence of rifamycin was studied in different Escherichia coli strains that vary in RNase content but are not isogenic: AB259 RNase+, Q13 RNase I- PNPase-, AB105 RNase I- RNase III-. It was found that rifamycin did not affect characteristics of phage replication such as the general pattern of viral RNA synthesis and

3. Escherichia coli mutant temperature sensitive for group I RNA bacteriophages.
The temperature-sensitive conjugational transfer-deficient mutant Escherichia coli JCFL39, carrying a traD(Ts) mutation, is herein described as also being temperature sensitive for group I RNA phages (MS2, f2, and R17) but not for Q beta. Temperature shift experiments showed that the growth of group I phage MS2 in the mutant could be inhibited by a post-pene

4. Model for Bacteriophage T4 Development in Escherichia coli
Mathematical relations for the number of mature T4 bacteriophages, both inside and after lysis of an Escherichia coli cell, as a function of time after infection by a single phage were obtained, with the following five parameters: delay time until the first T4 is completed inside the bacterium (eclipse period, ν) and its standard deviation (ς), the rate at

5. Isolation and characterization of a heat-inducible simian virus 40 mutant.
We have isolated a new type of temperature-sensitive mutant of simian virus 40 (SV40) that is capable of productive infection in permissive cells but not of maintenance of viral DNA integration in transformed cells at the conditional temperature. Virus development is induced when cells transformed by this mutant are shifted to temperatures above 39 degrees C

6. Bacterial rep- mutations that block development of small DNA bacteriophages late in infection.
Several related mutants of Escherichia coli C have been isolated that block the growth of the small icosahedral DNA phages phiX174 and S13 late in infection. Phage G6 is also blocked, at a stage not yet known. Growth of the filamentous phage M13, though not blocked, is affected in these strains. These host mutations co-transduce with ilv at high frequency, a

7. Bacteriophage Deoxyribonucleate Infection of Competent Bacillus subtilis1
Reilly, Bernard E. (Western Reserve University, Cleveland, Ohio), and John Spizizen. Bacteriophage deoxyribonucleate infection of competent Bacillus subtilis. J. Bacteriol. 89:782–790. 1964.—Phenol extracts of the Bacillus subtilis bacteriophages φ1, φ25, and φ29 contained infectious deoxyribonucleic acid. The infectivity was destroyed by catalytic am

8. Differential Expression of Bacteriophage Genomes in Vegetative and Sporulating Cells of Bacillus subtilis
Two antigenically distinct bacteriophages, β3 and β22, have been isolated and characterized with Bacillus subtilis strain W23 as a host. They differ in plaque morphology, single-step growth characteristics, host range, and thermal stability. The deoxyribonucleic acids isolated from β3 and β22 differ in base composition, density in CsCl and Cs2SO4, sedime
