Development and Validation of Molecular Assays for Limited Tissue Samples.

Acta Cytol 2019 Apr 17:1-8. Epub 2019 Apr 17.

Center for Personalized Diagnostics, Department of Pathology and Laboratory Medicine, University of Pennsylvania, Philadelphia, Pennsylvania, USA,

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.

Recognition of silver cations by multifarene[2,2] chemosensors with unexpected fluorescence response.

Spectrochim Acta A Mol Biomol Spectrosc 2019 Apr 9;218:213-220. Epub 2019 Apr 9.

Institute of Biomedical & Health Engineering, Shenzhen Institutes of Advanced Technology, Chinese Academy of Sciences, 1068 Xueyuan Avenue, Shenzhen 518055, China. Electronic address:

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.

The effect of myo-inositol/di-chiro-inositol on markers of ovarian reserve in women with PCOS undergoing IVF/ICSI: a systematic review and meta-analysis.

Acta Obstet Gynecol Scand 2019 Apr 16. Epub 2019 Apr 16.

Women's Health and Perinatology Research Group, Department of Clinical Medicine, UiT-The Arctic University of Norway, Tromsø, Norway.

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

Department of Pharmaceutics, the First Affiliated Hospital of Xinxiang Medical University, No. 88 Jiankang Road, Weihui, 453100, Henan, People's Republic of China.

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

5-ALA fluorescence-guided surgery in pediatric brain tumors-a systematic review.

Acta Neurochir (Wien) 2019 Apr 13. Epub 2019 Apr 13.

Department of Neurosurgery, University Hospital Münster, Germany Albert-Schweitzer-Campus 1, Building A1, 48149, Munster, Germany.

Background: 5-Aminolevulinic acid (5-ALA)-guided resection of gliomas in adults enables better differentiation between tumor and normal brain tissue, allowing a higher degree of resection, and improves patient outcomes. In recent years, several reports have emerged regarding the use of 5-ALA in other brain tumor entities, including pediatric brains tumors. Since gross total resection (GTR) of many brain tumors in children is crucial and the role of 5-ALA-guided resection of these tumors is not clear, we sought to perform a comprehensive literature review on this topic.
