We have developed a new system of chromosomal mutagenesis in order to study the functions of uncharacterized open reading frames (ORFs) in wild-type Escherichia coli. Because of the operon structure of this organism, traditional methods such as insertional mutagenesis run the risk of introducing polar effects on downstream genes or creating secondary mutations elsewhere in the genome. Our syste...
Impingement between the Achilles tendon and posterosuperior prominence of calcaneus is considered to be a cause insertional tendinopathy. The corresponding treatment intends reduce tensile stress from calf muscles avoid hyper-dorsiflexion ankle joint for decreasing contact pressure; however, no study has reported on whether these treatments can decrease impingement. Thus, this investigated hypo...
Pseudomonas stutzeri has type IV pili for which the pilA gene (here termed pilAI) provides the structural protein and which are required for DNA uptake and natural genetic transformation. Downstream of pilAI we identified a gene, termed pilAII, coding for a deduced protein with a size similar to that of PilAI with 55% amino acid sequence identity and with a typical leader peptide including a le...
BACKGROUND Results of high-energy extracorporeal shock wave therapy for the treatment of insertional Achilles tendinopathy are not determined. It is unclear how local anesthesia alters the outcome of this procedure. HYPOTHESIS Extracorporeal shock wave therapy is an effective treatment for insertional Achilles tendinopathy. Local anesthesia field block adversely affects outcome. STUDY DESIG...
BACKGROUND Most common systems of genetic engineering of mammalian cells are associated with insertional mutagenesis of the modified cells. Insertional mutagenesis is also a popular approach to generate random alterations for gene discovery projects. A better understanding of the interaction of the structural elements within an insertional mutagen and the ability of such elements to influence h...
To better understand the defense mechanism of Streptococcus thermophilus against superoxide stress, molecular analysis of 10 menadione-sensitive mutants, obtained by insertional mutagenesis, was undertaken. This analysis allowed the identification of 10 genes that, with respect to their putative functions, were classified into five categories: (i) those involved in cell wall metabolism, (ii) th...
Single-nucleotide polymorphism was used in the construction of an expressed sequence tag map of Aegilops tauschii, the diploid source of the wheat D genome. Comparisons of the map with the rice and sorghum genome sequences revealed 50 inversions and translocations; 2, 8, and 40 were assigned respectively to the rice, sorghum, and Ae. tauschii lineages, showing greatly accelerated genome evoluti...
T-cell receptors (TCRs) and chimeric antigen receptors recognizing tumor-associated antigens (TAAs) can now be engineered to be expressed on a wide array of immune effectors. Engineered receptors targeting TAAs have most commonly been expressed on mature T cells, however, some have postulated that receptor expression on immune progenitors could yield T cells with enhanced potency. We generated ...
Uptake and translocation of metal nutrients are essential processes for plant growth. Graminaceous species release phytosiderophores that bind to Fe(3+); these complexes are then transported across the plasma membrane. We have characterized OsYSL15, one of the rice (Oryza sativa) YS1-like (YSL) genes that are strongly induced by iron (Fe) deficiency. The OsYSL15 promoter fusion to beta-glucuron...
