Genetic modification of cells and animals is an invaluable tool for biotechnology and biomedicine. Currently, integrating vectors are used for this purpose. These vectors, however, may lead to insertional mutagenesis and variable transgene expression and can undergo silencing. Scaffold/matrix attachment region-based vectors are nonviral expression systems that replicate autonomously in mammalia...

pEPI-1, a vector in which a chromosomal scaffold/matrix-attached region (S/MAR) is linked to the simian virus 40 origin of replication, is propagated episomally in CHO cells in the absence of the virally encoded large T-antigen and is stably maintained in the absence of selection pressure. It has been suggested that mitotic stability is provided by a specific interaction of this vector with com...

The vector pEPI was the first nonviral and episomally replicating vector. Its functional element is an expression unit linked to a chromosomal scaffold/matrix attached region (S/MAR). The vector replicates autonomously with low copy number in various cell lines, is mitotically stable in the absence of selection over hundreds of generations, and was successfully used for the efficient generation...

These are representative examples director?s experimental artistic poetics based interweaving local global cultural features. focus ...

Derivatives of a cryptic plasmid from Lactobacillus curvatus showed temperature-sensitive replication in thermophilic lactobacilli. The thermosensitive replicon was used to construct the new delivery vector pTN1, which allows site-specific replacement of chromosomal DNA sequences. pTN1 carries an erythromycin resistance marker suitable for selection of single-copy integrants and replicates read...

The gene for proline iminopeptidase from Lactobacillus delbrueckii subsp. lactis DSM 7290 coding for an enzyme that hydrolyses the synthetic substrate L-prolyl-beta-naphthylamide (Pro-beta NA) was cloned in Escherichia coli. An enzymic plate assay was used to screen for positive clones. The gene, designated pepI, was subcloned into vector pUC18 and sequenced. The nucleotide sequence revealed an...

Perovskites have been the focus of attention due to their multitude outstanding optoelectronic properties and structural versatility. Two-dimensional halide perovskite such as (C_6H_5C_2H_4NH_3)_2PbI_4, or simply PEPI, forms natural multiple quantum wells with enhanced light-matter interactions, making them attractive systems for further investigation. This work reports tunable splitting excito...

BACKGROUND Understanding how tumor response is related to relapse risk would help clinicians make decisions about additional treatment options for patients who have received neoadjuvant endocrine treatment for estrogen receptor-positive (ER+) breast cancer. METHODS Tumors from 228 postmenopausal women with confirmed ER+ stage 2 and 3 breast cancers in the P024 neoadjuvant endocrine therapy tr...
