2. Abrogation of radiation leukemia virus-induced lymphomagenesis by antisera to thymotropic but not to ecotropic or dual-tropic viruses.
Leukemia induction by culture-grown thymotropic radiation leukemia virus or by tumor-derived virus present in cell-free tumor extracts was abrogated by incubation of either virus with anti-thymotropoc virus serum, but not by antiserum raised against ecotropic or dual-tropic (mink cell focus-inducing type) viruses that were isolated from radiation leukemia vi

3. Evaluation of the rapid and slow maxillary expansion using cone-beam computed tomography: a randomized clinical trial
RESUMO OBJETIVO: o objetivo do presente ensaio clínico randomizado foi avaliar as transformações dentárias, dentoalveolares e ósseas que ocorrem imediatamente após o tratamento com expansão rápida da maxila (ERM) e lenta (ELM) usando expansores do tipo Haas. MÉTODOS: todos os indivíduos foram submetidos a tomografias computadorizadas de feixe c

4. P74 Mediates Specific Binding of Autographa californica M Nucleopolyhedrovirus Occlusion-Derived Virus to Primary Cellular Targets in the Midgut Epithelia of Heliothis virescens Larvae
P74, an envelope protein of the occlusion-derived virus (ODV) of Autographa californica M nucleopolyhedrovirus (AcMNPV), is critical for oral infection of Trichoplusia ni larvae. The role of P74 during primary infection, however, is unknown. Here we provide evidence that P74 facilitates binding of AcMNPV ODV to a specific receptor within the larval midgut ep

5. Nanoparticle-coated organic-inorganic microparticles: experimental design and gastrointestinal tolerance evaluation
The influences of the spray-drying parameters and the type of nanoparticles (nanocapsules or nanospheres) on the characteristics of nanoparticle-coated diclofenac-loaded microparticles were investigated by using a factorial design 3². Gastrointestinal tolerance following oral administration in rats was evaluated. Formulations were selected considering the b

6. Landau levels in two and three-dimensional electron gases in a wide parabolic quantum well
Shubnikov-de Haas oscillations are measured in a wide parabolic quantum well with 6 subbands in a tilted magnetic fi eld. We find two types of oscillations. The oscillations at low magnetic field are shifted towards higher fields with tilted angles, and can be attributed to the two-dimensional Landau state at the bottom subband. The position of the second ty

7. A developmentally regulated DNA-binding protein from mouse brain stimulates myelin basic protein gene expression.
Transcription of the myelin basic protein (MBP) gene is regulated in a cell-type-specific and developmental stage-specific manner during myelin formation in the murine central nervous system. The 5'-flanking region of the MBP gene contains several regulatory elements that differentially contribute to the cell-type-specific transcription of MBP in cells deriv

8. A new agent of mycobacterial lymphadenitis in children: Mycobacterium heidelbergense sp. nov.
Nontuberculous mycobacterial lymphadenitis presents an increasing clinical problem in immunocompetent young children. A slowly growing, nonphotochromogenic mycobacterium was recovered twice (isolates 2553/91 and 2554/91) from the lymphatic tissue of a child with recurrent cervical lymphadenitis. It could be differentiated biochemically from described Mycobac

9. Evolutionary variation in bacterial RNase P RNAs.
Sequences encoding RNase P RNAs from representatives of the last remaining classical phyla of Bacteria have been determined, completing a general phylogenetic survey of RNase P RNA sequence and structure. This broad sampling of RNase P RNAs allows some refinement of the secondary structure, and reveals patterns in the evolutionary variation of sequences and

10. Release of soluble pilin antigen coupled with gene conversion in Neisseria gonorrhoeae.
Gene conversion appears to be the frequent mechanism in Neisseria gonorrhoeae that leads to an altered expression of pilin, the subunit component of the pili. In this process segments of variable sequence information, the minicassettes, are transferred from silent storage loci into an expression locus. As a putative consequence of the rearrangement in the pi

11. Escherichia coli Insertion Sequence IS150: Transposition via Circular and Linear Intermediates
IS150, a member of the widespread IS3 family, contains two consecutive out-of-phase open reading frames, orfA and orfB, that partially overlap. These open reading frames encode three proteins, InsA, InsB, and the InsAB protein, which is jointly encoded by both open reading frames by means of programmed translational frameshifting. We demonstrate that the Ins

12. Cloning, characterization, and expression in Escherichia coli of a gene encoding Listeria seeligeri catalase, a bacterial enzyme highly homologous to mammalian catalases.
A gene coding for catalase (hydrogen-peroxide:hydrogen-peroxide oxidoreductase; EC 1.11.1.6) of the gram-positive bacterium Listeria seeligeri was cloned from a plasmid library of EcoRI-digested chromosomal DNA, with Escherichia coli DH5 alpha as a host. The recombinant catalase was expressed in E. coli to an enzymatic activity approximately 50 times that of
