Bacteriophage phi2 is unable to replicate in Bacillus subtilis 168. Although some phage deoxyribonucleic acid (DNA) synthesis can occur, the DNA made is not biologically active and sedimentation analysis reveals that it is smaller in size than that of mature DNA or DNA isolated from phi2-infected permissive hosts. Messenger ribonucleic acid hybridizable with phi2 DNA is also synthesized in phi2...

The gene encoding extracellular xylanase (xynA) was amplified as a 770 bp DNA fragment from Bacillus subtilis 168 chromosomal DNA by PCR. The genes encoding endo-beta-1,4-glucanase (eglS) and endo-beta-1,3-1,4-glucanase (bglS) were isolated from a genomic library of B. subtilis 168. The sequences of xynA and eglS were identical to those of the xylanase and cellulase genes from B. subtilis PAP11...

The Bacillus subtilis merodiploid strain GSY1127 contains a large nontandem duplication of a portion of its chromosome within its left (anticlockwise) replication segment. This causes displacement of the replication terminus region to a noticeably asymmetric location relative to oriC. The utilization of the subsidiary replication terminators, TerIII and TerV, in the merodiploid strain has been ...

OBJECTIVE To investigate the association of a single-nucleotide polymorphism (SNP) in the promoter region of MHC2TA gene (-168*G/A, rs3087456), which has previously been described in a Swedish rheumatoid arthritis (RA) cohort, in British Caucasian RA patients. METHODS We genotyped 733 RA patients and 613 healthy controls for MHC2TA -168*G/A SNP by amplification-refractory mutation system (ARM...

OBJECTIVE The objective of this study was to investigate the feasibility of examining the fetal heart with Tomographic Ultrasound Imaging (TUI) using four-dimensional (4D) volume datasets acquired with spatiotemporal image correlation (STIC). MATERIAL AND METHODS One hundred and ninety-five fetuses underwent 4D ultrasonography (US) of the fetal heart with STIC. Volume datasets were acquired w...

We developed a straightforward, rapid, and inexpensive method to determine transgene copy number in tobacco. The plasmid (pSSRCopy) used for tobacco transformation contains a simple sequence repeat (SSR) locus, PT1199, which was partially deleted in the middle, a homogenous SSR locus in tobacco K326. A 168-bp segment of the cloned PT1199 was shortened to 95 bp by deleting a 73-bp internal fragm...

We evaluated ultrasonography (US) findings between benign and malignant phyllodes tumors and analyzed diagnostic performance of US-guided core needle biopsy (CNB) for phyllodes tumors. Surgically removed phyllodes tumors of 168 women were divided into two groups according to the benign and malignant (including borderline tumor) groups and 116 were benign and 52 were malignant. On US, the comple...

Plasma concentrations and pharmacokinetics of enrofloxacin were determined in 12 loggerhead sea turtles (Caretta caretta) after oral administration. Six turtles in group 1 and group 2 received enrofloxacin at 10 mg/kg and 20 mg/kg of body weight, respectively. Blood was collected from the cervical sinus before administration and at timed intervals up to 168 hr following administration. Plasma c...
