The recent development of tetracycline (tet)-regulated transactivation systems for inducible gene expression has dramatically enhanced the tools available for the temporal and quantitative control of exogenous genes in mammalian cells and transgenic mice and plants. Such systems have applications in many areas of biology and medicine, including the study of gene regulation and function in devel...

The coordination properties of the ligand 2,2'-bipyrimidine-4,4'-dicarboxylic acid (H2bpd) with lanthanide(III) ions (Ln = Eu, Tb, or Lu) were investigated. syntheses H2bpd and its salts, [K2(bpd)(H2O)2] (1) [(AlkNH)Lu(bpd)2] (Alk Et, Hex, en), are described. In presence LnCl3 salts Lu, Tb), formation [Ln(bpd)2]- [Ln(bpd)(H2O)x]+ species was assessed by 1H nuclear magnetic resonance (NMR), spec...

This review highlights the advancement of molecular triplet donors showing singlet-to-triplet (S–T) absorption and their utilization for triplet-triplet annihilation-based photon upconversion (TTA-UC). Circumvention thermal energy loss associated with intersystem crossing (ISC) through use S–T results in UC from near-infrared (NIR) light to yellow, blue, even violet light, achieving an unpreced...

In this study, molecular simulation is utilized to explore the charge effect in COF membranes on separation performance. Three types of with different functional groups (Tp-Tta-COOH, Tp-Tta-COO − and Tp-Tta-NH 3 + ) thus charges are designed. It found that positively charged membrane (Tp-Tta-NH shows higher ion selectivity mixed Li /Mg 2+ solution, compared negatively neutral membranes. membran...

Congenital pericardial defects (CPDs) are infrequent anomalies that are usually asymptomatic and are discovered incidentally during unrelated interventions. Here we report the case of a CPD with herniation of an enlarged left atrial appendage identified during total thoracoscopic ablation (TTA) for persistent atrial fibrillation (AF). The persistent AF was successfully treated with a hybrid pro...

Since 2009, the National Criminal Justice Association (NCJA), with support from the Bureau of Justice Assistance (BJA), has provided training and technical assistance (TTA) in strategic planning to State Criminal Justice Administering Agencies (SAAs) in 20 states, 2 territories, and the District of Columbia. TTA services have been tailored to the needs, planning scopes, and timelines establishe...

Tolyltriazole (TTA) is a well-defined corrosion inhibitor for copper and alloys. However, there little literature about its inhibition performance mild steels in corrosive environments. This paper studied the electrochemical behavior of TTA 0.5 M HCl solutions. Also, morphology nature layers on steel surface were investigated. Electrochemical results showed that an excellent acidic media with e...

Abstract Funding Acknowledgements Type of funding sources: None. Backgrounds Atrial fibrillation (AF) event during blanking period is a risk factor for late recurrence AF in patients undergoing ablation. The aim this study was to investigate clinical implications left atrial (LA) strain long-term outcome experiencing early after totally thoracoscopic ablation (TTA). Methods A total 128 who unde...

AIMS Myocardial fatty acid (FA) oxidation is regulated acutely by the FA supply and chronically at the transcriptional level owing to FA activation of peroxisome proliferator-activated receptor-alpha (PPARalpha). However, in vivo administration of PPARalpha ligands has not been shown to increase cardiac FA oxidation. In this study we have examined the cardiac response to in vivo administration ...
