This years’ American Society for Mass Spectrometry Sanibel meetin

This years’ American Society for Mass Spectrometry Sanibel meeting brought together established scientists who have demonstrated the viability of the top-down approach and its applicability to virtually all segments of the proteome, mixing them with researchers from diverse areas and with the common interest of advancing top-down into the high-throughput proteomics mainstream. Advances in instrumentation

including the orbitrap analyzer, ionization mechanisms, dissociation CX-5461 DNA Damage inhibitor strategies and informatics, as well as a wide variety of applications, were discussed in depth, leading to the inescapable conclusion that the future for top-down is bright.”
“A new actinomycete strain designated as Streptomyces sp. CTF15 was isolated from a saline soil using casein-KNO3 agar medium. The strain Streptomyces sp. CTF15 exhibited promising antimicrobial activity against Staphylococcus aureus, Bacillus subtilis, Streptomyces viridochromogens Tu57 and high cytotoxicity (91.2% mortality) against Artimia salina in biological screening. The cultivation of this strain in a 50 L lab fermenter and subsequent isolation and purification by a Sepantronium solubility dmso series of chromatographic techniques and structure elucidation by MS and NMR analysis of the active metabolites

revealed that it is a highly stable producer of resistomycin (1), tetracenomycin D (2) and actinomycin D (3), even under non-optimised culture conditions.

The morphological, microscopic, biochemical and physiological characterisation suggested that the strain CTF15 belongs to the genus Streptomyces. A partial 16S rRNA gene sequence (1429 bp) from the strain CTF15 was determined and found to have high identity (99%) with Streptomyces griseoincarnatus. As such, this is the first report of a strain of S. griseoincarnatus capable of producing Tucidinostat in vivo these three bioactive compounds simultaneously.”
“Expert Rev. Proteomics 10(2), 131-134 (2013) Evaluation of: Wapner RJ, Martin CL, Levy B etal. Chromosomal microarray versus karyotyping for prenatal diagnosis. N. EngL J. Med. 367(23), 2175-2184 (2012). Prenatal diagnosis is now offered to high-risk pregnancies, including advanced maternal age, ultrasound anomalies and positive Down’s syndrome screening, and karyotype on cultured fetal material is the test of choice to screen these pregnancies. However, microscope analysis can only detect gross chromosome abnormalities, highlighting the need for more sensitive techniques. It has recently been established that the higher resolution of microarray-based platforms can increase the diagnostic yield, offering more information to couples, and it is being discussed as a replacement to the standard karyotype.
