Aminoacyl-tRNA synthetases activate specific amino acid substrates and attach them via an ester linkage to cognate tRNA molecules. In addition to cognate proline, prolyl-tRNA synthetase (ProRS) can activate cysteine and alanine and misacylate tRNA(Pro). Editing of the misacylated aminoacyl-tRNA is required for error-free protein synthesis. An editing domain (INS) appended ...

Naturally occurring carbohydrate polymers are ubiquitous. They are assembled by polymerizing glycosyltransferases, which can generate polysaccharide products with repeating sequence patterns. The fidelity of enzymes of this class is unknown. We report a method for testing the fidelity of carbohydrate polymerase pattern deposition: we synthesized fluorosugar donors and used them ...

Cyclic AMP response element binding protein (CREB) is often dysregulated in cancer cells and is an attractive cancer drug target. Previously, we described naphthol AS-E (1) as a small molecule inhibitor of CREB-mediated gene transcription. To understand its bioactive conformation, a series of conformationally constrained analogues of 1 were designed ...

This article reports a method for precise detection of single chemicals. The hub of ...

While compressed sensing (CS)-based algorithms have been developed for the low-dose cone beam CT (CBCT) reconstruction, a clear understanding of the relationship between the image quality and imaging dose at low-dose levels is needed. In this paper, we qualitatively investigate this subject in a comprehensive manner with extensive experimental and ...

One of the key constituents of the muraymycins is the 6-membered cyclic guanidine, (2S,3S)-muraymycidine (or epi-capreomycidine). In order to diversify the structure of the oligopeptide moiety of the muraymycins for thorough structure-activity relationship studies, we have developed a highly stereoselective synthesis of ureidomuraymycidine derivatives with the lactone 4a.

The anti-neoplastic agent didemnin B from the Caribbean tunicate Trididemnum solidum was the first marine drug to be clinically tested in humans. Because of its limited supply and its complex cyclic depsipeptide structure, considerable challenges were encountered during didemnin B's development that continue to limit aplidine (dehydrodidemnin B), which is ...

Viral capsid dynamics are often observed during infectious events such as cell surface attachment, entry and genome release. Structural analysis of adeno-associated virus (AAV), a helper-dependent parvovirus, revealed a cluster of surface-exposed tyrosine residues at the icosahedral two-fold symmetry axis. We exploited the latter observation to carry out selective oxidation ...

Microarrays of RNA aptamers are fabricated in a one-step, multiplexed enzymatic synthesis on gold thin films in a microfluidic format and then employed in the detection of protein biomarkers with surface plasmon resonance imaging (SPRI) measurements. Single-stranded RNA (ssRNA) oligonucleotides are transcribed on-chip from double-stranded DNA (dsDNA) templates attached to ...

Long-term anticoagulation with warfarin is the mainstay of treatment in patients with diseases with high thromboembolic potential, such as atrial fibrillation. However, warfarin therapy carries a number of inherent limitations, including slow onset and offset of action, interindividual variability, food and drug interactions, lack of selectivity and a narrow therapeutic ...

Adherence to medications is poor and suboptimal in many chronic diseases. Nonadherence can reduce treatment effectiveness and can have an impact on healthcare costs. As a consequence, it may alter the cost-effectiveness of drug therapies. This article emphasizes the importance of integrating medication compliance and persistence into pharmacoeconomic evaluations, using ...

The search for new anti-hepatitis C virus (HCV) therapeutics continues as the current treatment, consisting of PEGylated IFN-α and ribavirin, is of limited efficacy, nonspecific and can cause significant side effects. Modified nucleoside analogues with improved efficacy and selectivity, may become the backbone of the future standard of care for ...

Monensin (tradename: Rumensin) should reduce the extent of amino acid deamination in the rumen, and supplemental fat should decrease protozoal abundance and intraruminal N recycling. Because animal-vegetable (AV) fat can be biohydrogenated in the rumen and decrease its effectiveness as an anti-protozoal agent, we included diets supplemented with coconut oil ...

The fundamental philosophy of NOLS is ...

Bisphosphonates (BPs) have been used for the management of bone metabolic diseases. Currently their therapeutic use has increased, as also have their adverse effects, one of the most important being the bisphosphonate-related osteonecrosis of the jaw (BRONJ), a complication of difficult treatment and solution. Until now, the physiopathology of BRONJ ...

Many kinase inhibitors, chemotherapeutic agents, antiemetics, antibiotics, and antifungal agents can prolong QT intervals, placing the patient as risk for the life-threatening ventricular arrhythmia Torsade de pointes (Tdp). In addition, common electrolyte imbalances experienced by many patients with cancer compound the risk. Because numerous medications used in oncology and common ...
