Benzanthrone derivatives show interesting solvent dependent photophysical properties. Understanding of their photophysical properties is essential for developing the fluorescence probes based on benzanthrone derivatives. The photophysical properties of 3-(N'-chlorophenyl)piperazino-7H-benzo[de]anthracen-7-one [ClPh-PBA] molecule are reported in different solvents and solvent mixtures. Read More

Protein phase transition can generate non-membrane bound cellular compartments, which can convert from liquid-like to solid-like states. While the molecular driving forces of phase separation have been largely understood, much less is known about the mechanisms of material-state conversion. We apply a recently developed algorithm to describe the weak interaction network of multivalent motifs, and simulate the effect of pathological mutations. Read More

Background: Knowledge regarding the barrier properties of human skin is important for understanding skin pathology, developing of transdermal drug delivery systems and computational skin absorption models; however, the molecular pathways through human skin remains to be fully investigated on a nanoscopic level. In particular the nanoscopic pathway of molecules passing the intercellular lipid bilayers separating the corneocytes in the stratum corneum (SC) is not fully elucidated.

Methods: Using stimulated emission depletion microscopy (STED) and Förster resonance energy transfer (FRET) the molecular pathways through the SC, the main barrier of the skin, are determined for lipophilic and water-soluble molecules at a nanoscopic resolution. Read More

This review (with 177 refs) gives an overview on nanomaterial-based methods for the determination of uranyl ion (UO) by different types of transducers. Following an introduction into the field, a first large section covers the fundamentals of selective recognition of uranyl ion by receptors such as antibodies, aptamers, DNAzymes, peptides, microorganisms, organic ionophores (such as salophens, catechols, phenanthrolines, annulenes, benzo-substituted macrocyclic diamides, organophosphorus receptors, calixarenes, crown ethers, cryptands and β-diketones), by ion imprinted polymers, and by functionalized nanomaterials. A second large section covers the various kinds of nanomaterials (NMs) used, specifically on NMs for electrochemical signal amplification, on NMs acting as signal tags or carriers for signal tags, on fluorescent NMs, on NMs for colorimetric assays, on light scattering NMs, on NMs for surface enhanced Raman scattering (SERS)-based assays and wireless magnetoelastic detection systems.

As the value of molecular testing of cancer specimens increases, the number of tests imposed on tumor specimens also increases, often in tension with the amount of tumor material available. To develop and validate molecular assays for limited specimens, there are specific concerns that must be addressed, including DNA quality, quantity, and abundance; the number of targets/ability to multiplex; and the analytical sensitivity and specificity of the assay itself. Ultimately, weighing these considerations during assay validation in the overall context of clinical utility and laboratory workflow is critical for delivering the highest level of personalized care to patients.

Fluorescent chemosensors based on a new macrocyclic compound, multifarene[2,2], with modification by triazole-linked pyrene or anthracene were synthesized. These macrocyclic sensors exhibited high affinity and selectivity toward Ag over other metal ions, with ratiometric or enhanced response of their fluorescence emissions depending upon the substituent species for coordination to Ag, and an unexpected response to a concentration threshold of the metal cations was discovered. The experimental evidences of fluorescence spectra, H NMR titration, IR spectra, and high-resolution mass spectra suggested the coordination behaviors of the sensors with Ag, that is, the 1:1 complexes were formed with moderate association constants of about 10 L·mol, and the sulfur atoms on macrocyclic ligand should affinite to the metal cations.

Four novel highly selective 8-hydroxyquinoline-based fluorescent chemodosimeters (1-4) were synthesized for the rapid analysis of Hg in aqueous solution and on paper strips, which probably attributed to the excited state intramolecular proton transfer (ESIPT) process. Chemodosimeter 1 was evaluated as a Hg-ratiometric fluorescent sensor while others (2, 3 and 4) displayed fluorescence turn-on response for Hg among the various survey metal ions. We demonstrated that chemodosimeters (1-4) could recognized Hg ions based on a 1:1 stoichiometric binding event with fast detection time. Read More

Introductio: High levels of anti-Mullerian hormone and a high antral follicle count in women with polycystic ovary syndrome, reflecting increased ovarian antral follicles, predisposes them to have a high number of retrieved oocytes at in-vitro fertilisation (IVF)/ intra-cytoplasmic sperm injection (ICSI) and an increased risk of ovarian hyperstimulation syndrome. Inositols, which act as insulin sensitizers have the potential to alter folliculogenesis and the functional ovarian reserve with subsequent benefits to reproductive outcomes following IVF/ICSI treatment. Published literature is however unable to provide definitive evidence of its efficacy. Read More

Aims: Metabolic surgery is considered as a therapeutic option for obese patients with type 2 diabetes (T2D). In order to identify novel laboratory variables that could improve the selection of patients who might greatly benefit from a surgical approach, we focused on the neutrophil-to-lymphocyte ratio (NLR) as a predictor of long-term T2D remission following metabolic surgery.

Neuropathic pain is a major public health problem because it has a considerable impact on life quality of patients. Neuropathic pain caused by a lesion or disease of the somatosensory nervous system, which causes unpleasant and abnormal sensation (dysesthesia), an increased response to painful stimuli (hyperalgesia), and pain in response to a stimulus that does not normally provoke pain (allodynia). P2X receptors from dorsal root ganglion (DRG) play a crucial role in facilitating pain transmission at peripheral and spinal sites. Read More
