A general method of estimation with a variable observed subject to a limit of detection is introduced. It is based on extrapolation of the estimates obtained by increasing the limit of detection. Theoretical arguments support the method in some special cases, and it is explored by simulations. Several examples are ...

A simple one-pot method for the preparation of subnanometre-size benzotriazolate (BTA) protected copper clusters, Cu(n)BTA(m), is reported. The clusters were analyzed by optical and infrared spectroscopy, mass spectrometry and transmission electron microscopy together with computational methods. We suggest a structural motif where the copper core of the Cu(n)BTA(m) clusters is ...

The synthesis of the tricyclic angular chromone structure originally assigned to aspergillitine is reported. The synthesis was achieved in 11 steps and 15% overall yield from 2,4-dihydroxypropiophenone, through the intermediacy of 2,3-dimethyl-7-hydroxychromen-4-one. Construction of the nitrogen-bearing heterocyclic ring entailed a Stille cross-coupling reaction with n-Bu(3)SnCH(2)CH[double bond, length as m-dash]CH(2), followed ...

The nuclear encoded chloroplast sHSPs are present in all plant species from algae to angiosperms. Expression analysis shows that the wheat chloroplastic sHSP (HSP26) is highly inducible by heat stress in almost all the vegetative and generative tissues and is also expressed constitutively in certain developmental growth stages. We characterize ...

Concurrent infection with hepatitis B virus (HBV) and hepatitis C virus (HCV) in patients positive for human immunodeficiency virus (HIV) is relatively common. The treatment of co-infected individuals is rather complex because the anti-viral therapy may be associated with drug-resistance, hepatotoxicity and lack of response. Herein, we present a summary ...

Cyclic nitroxide radicals represent promising alternatives to the iodine-based redox mediator commonly used in dye-sensitized solar cells (DSSCs). To date DSSCs with nitroxide-based redox mediators have achieved energy conversion efficiencies of just over 5 % but efficiencies of over 15 % might be achievable, given an appropriate mediator. The efficacy of the ...

Different studies have proved that the resistance/susceptibility to mastitis is genetically determined. The major histocompatibility complex in cows is known as bovine lymphocyte antigen (BoLA). Genes from the BoLA have been associated with the occurrence of infectious diseases such as mastitis and leukosis, especially the BoLA-DRB gene. The object of ...

Matrix-assisted laser desorption/ionization mass spectrometry is an established soft ionization method that is widely applied to analyze biomolecules. The UV-absorbing organic matrix is essential for biomolecule ionization; however, it also creates matrix background interference, which results in problematic analyses of biomolecules of less than 700 Da. Therefore, this study investigates ...

Blood vessels and endothelial cells (ECs) are highly versatile in order to accomplish local tissutal needs in the physiological and pathological conditions. Tumor vasculature, in particular, exhibits special morphological and functional features, partly due to the peculiarity of tumor-derived ECs (TECs). This is of great importance for the discovery of ...

BACKGROUND: Metastatic breast cancer (MBC) is generally incurable. However, 10-20-year relapse-free survival of MBC is approximately 2%, implying that at least a small subset of MBC patients achieve prolonged survival. We therefore analyzed long-term outcome in a particular subset, i.e., oligometastatic breast cancer (OMBC). METHODS: Data of OMBC subjects (N = 75) ...

To evaluate efficacy in multiple endpoints in confirmatory clinical trials is a challenging problem in multiple hypotheses testing. The difficulty comes from the different importance of each endpoint and their underlying correlation. Current approaches to this problem, which test the efficacy in certain dose-endpoint combinations and collate the results, are ...

There is convincing evidence to suggest a strong genetic component to psoriatic arthritis (PsA), with studies reporting a 40-fold risk to first-degree relatives of patients with disease. However, compared with rheumatoid arthritis, our understanding of the genetic etiology of PsA is less well-developed. Only three modestly sized genome-wide association studies ...

IL-6 plays a key role in local and systemic manifestation of RA. IL-6 is not only a pro-inflammatory cytokine, but also interacts in complex ways with the cells involved in bone remodeling. In RA, IL-6 may indirectly promote osteoclastogenesis by increasing the release of RANK-L by osteoblasts, and it diminishes ...

Radiofluorinated 4-fluorobenzonitrile oxide and N-hydroxy-4-fluorobenzimidoyl chloride rapidly react with different alkenes and alkynes under mild conditions. These cycloadditions are suitable for the preparation of low-molecular weight radiopharmaceuticals and, in a strain-promoted variant, can enable easy labelling of sensitive biopolymers.
