ABSTRACT Escherichia coli mRNA interferases, such as MazF and ChpBK, are sequence-specific endoribonucleases encoded by toxin-antitoxin (TA) systems present in its genome. A homologue Staphylococcus aureus (MazF Sa ) has been shown to inhibit cell growth when induced E. . Here, we determined the cleavage site for with use of phage MS2 RNA a substrate CspA, an chaperone, which prevents formation secondary structures substrate. specifically cleaves at pentad sequence, U↓ACAU.

In this paper, we present an unobtrusive cuffless blood pressure (BP) monitoring system based on pulse arrival time (PAT) for facilitating long-term home BP monitoring. The proposed consists of electrocardiograph (ECG), a photoplethysmograph (PPG), and control circuit with Bluetooth module, all which are mounted common armchair to measure ECG PPG signals from users while sitting the in order calculate continuous PAT. Considering good linear correlation systolic (SBP) nonlinear diastolic...

Abstract The phase III double-blind PROPEL study compared the novel two-component therapy cipaglucosidase alfa + miglustat (cipa mig) with alglucosidase placebo (alg pbo) in adults late-onset Pompe disease (LOPD). This ongoing open-label extension (OLE; NCT04138277) evaluates long-term safety and efficacy of cipa mig. Outcomes include 6-min walk distance (6MWD), forced vital capacity (FVC), creatine kinase (CK) hexose tetrasaccharide (Hex4) levels, patient-reported outcomes safety. Data are...

The Mycobacterium tuberculosis genome harbors a striking number (>40) of toxin-antitoxin systems. Among them are at least seven MazF orthologs, designated MazF-mt1 through MazF-mt7, four which have been demonstrated to function as mRNA interferases that selectively target for cleavage distinct consensus sequences. As is characteristic all systems, each the mazF-mt toxin genes organized in an operon downstream putative antitoxin genes. However, only one upstream antitoxins (designated...

Four synthetic peptides (residues 20-30 and 17-34) within the growth factor-like domain (GFD) of murine human urokinase-type plasminogen activator (uPA) were examined to determine whether they inhibit production experimental spontaneous lung metastasis by Lewis carcinoma (3LL) cells. In an in vivo assay, which determines mainly later steps metastatic migration process (extravasation from bloodstream then into pulmonary tumor), none introduced i.v. single co-injection syngeneic C57B1/6 mice...

Emulsion polymerizations of styrene using poly(oxyethylene) nonylphenyl ether nonionic emulsifier were carried out at different and initiator (potassium persulfate, KPS) concentrations to prepare polystyrene (PS) seed particles with incorporated emulsifier. Seeded emulsion the PS amounts develop a novel method for preparation multihollow particles. When small amount used, non-hollow spherical prepared. However, obtained in case large Moreover, higher concentration particles, more effectively...

Chromophobe renal cell carcinoma (chRCC) is a tumor subtype with good prognosis, characterized by multiple chromosomal copy number variations (CNV). The World Health Organization (WHO) chRCC classification guidelines define classic and an eosinophilic variant. Large cells reticular cytoplasm prominent membranes (pale cells) are characteristic for chRCC. Classic variants were defined in 42 Swiss chRCCs, 119 Japanese chRCCs whole-slide digital images of 66 from the Cancer Genome Atlas (TCGA)...

Urinary trypsin inhibitor (UTI) inhibits efficiently tumor cell invasion and the formation of metastasis. The anti‐metastatic effect is dependent on COOH‐terminal domain II UTI [UTI‐(78−136)‐peptide]. To develop a molecule that binds with high affinity to urokinase (uPA) receptor (uPAR) surfaces, bifunctional hybrid [uPA‐(1−134)‐UTI‐(78−136)] consisting uPAR‐binding NH 2 ‐terminal fragment [UTI‐(78−136)‐peptide] uPA at ‐terminus UTI‐(78−136)‐peptide was produced in Escherichia coli by...
