Validation of a fast LC-MS/MS method for the analysis of bisphenol A (BPA) and urethane dimethacrylate (UDMA) in eluates of dental polymer-based materials

Scientific Reports
Polymer-based materials are widely used in dentistry. However, concerns exist regarding their biocompatibility because monomers such as urethane dimethacrylate (UDMA) and bisphenol A (BPA) may leach from the materials and affect the immune and endocrine ...

Pregnane steroids from a gorgonian coral Subergorgia suberosa with anti-flu virus effects

, 2016
Five new pregnane-type steroids namely subergorgols T-X (1-5) and three known analogues (6-8) were isolated from a gorgonian coral Subergorgia suberosa.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Bismuth(III) Reagents in Steroid and Terpene Chemistry

Molecules, 2011
Steroid and terpene chemistry still have a great impact on medicinal chemistry. Therefore, the development of new reactions or “greener” processes in this field is a contemporaneous issue.

Regulation of the lncRNA NEAT1 by p53‐ΔNp63 crosstalk modulates the DNA damage response and therapeutic efficacy in HNSCC

Molecular Oncology, EarlyView.
In head and neck squamous cell carcinoma (HNSCC) p53 and p63 exert opposite roles on the transcription regulation of the lncRNA NEAT1. Under basal conditions, p53 levels are low and p63 represses NEAT1 expression. Upon genotoxic stress, p53 is rapidly induced, displacing p63 from the NEAT1 promoter leading to NEAT1 transcriptional activation and ...

Risk factors for fragility fractures in patients with immunobullous diseases on long-term systemic glucocorticoids

Dermatology Reports
Dear Editor, Systemic glucocorticoids remain a cornerstone of therapy in immunobullous diseases. Yet little is known about glucocorticoid induced osteoporosis (GIOP) in patients with immunobullous diseases. We performed a retrospective review of medical

Time‐restricted feeding prior to Mycobacterium tuberculosis infection reduces tissue CD4+ T cells with limited impact on bacterial clearance

FEBS Open Bio, EarlyView.
Time‐restricted feeding (TRF) in mice increased liver fatty acid oxidation and decreased fatty acid biosynthesis. These alterations persisted when TRF was discontinued and the host was infected with Mycobacterium tuberculosis. Pre‐exposure to TRF did not alter tissue (lung and spleen) mycobacterial burden but significantly reduced CD3+ T cells in lungs

The impact of nandrolone decanoate and growth hormone on biosynthesis of steroids in rats

, 2013
Growth hormone (GH) and anabolic androgenic steroids (AAS) are commonly used in sports communities. Several studies have suggested an association between GH and AAS.

Luminescent rhenium fac-tricarbonyl-containing complexes of androgenic oxo-steroids [PDF]

, 2012
A new route to luminescent derivatives of androgenic steroids containing a ketone group in the 3- or 17-position has been developed. Reaction with the fac-Re(CO)3Cl complex of 3,3’-diamino-2,2’- bipyridine (complex 1) afforded a cyclic aminal product ...
