Exploring the role of the arginine-methylation writer-reader pair PRMT5/SND1 in JAK2-mutant myeloproliferative neoplasms
<p>Myeloproliferative neoplasms (MPNs) are a hematopoietic disease characterized by hyperproliferation of cells of the myeloid lineage for which current therapeutic options are limited. Discovered in 2005, the JAK2V617F mutation is the most common driver mutation in BCR-ABL negative MPNs, resulting …

An evaluation of a modified membrane filter procedure for enumerating stressed fecal coliforms in chlorinated sewage effluents
… technique that yields the most probable number (MPN), the standard MF technique (SF-MF), and a modified MF technique (IF-MF) which consisted of a lactose overlay and a 5-hour incubation period at 44.5°C. A statistical analysis of the data showed that the means of the recoveries by the IF-MF …

Effect of storage temperatures on the microbiological quality, safety, and viability of quahog clams, Mercenaria mercenaria
… fecal coliform counts ranged from < 0.3 to 61.1 MPN/g and < 0.3 to 24.4 MPN/g, respectively. During the summer, V. parahaemolyticus was isolated from 56% of the samples, with the highest concentration, 24,000 MPN/g, occurring on day 12 at 12.8°C.

Six-month field monitoring of point-of-use ceramic water filter by using H₂S paper strip most probable number method in San Francisco Libre, Nicaragua
… (H2S) Paper Strip Most Probable Number (H2S MPN) showed that an average of 80.4% of the sample population had less than 2.2 H2S producing colonies per 100 mL after filtration through the PFP filter. Six percent of the visited households had more than 16 CFU/100 mL after filtration. Over the 6 …

Investigating the anti-leukaemic effect of tamoxifen in the myeloproliferative neoplasms
Myeloproliferative neoplasms (MPNs) commonly result from the acquisition of somatic mutations affecting the Janus kinase 2 (JAK2) (such as JAK2<sup>V617F</sup>) or the multi-functional protein CALR (such as CALR<sup>Ins5</sup> and CALR<sup>Del52</sup>), causing the constitutive activation of signal …

The molecular pathogenesis of myeloproliferative neoplasms
Myeloproliferative neoplasms (MPNs) are a heterogeneous group of haematological stem cell<br/>malignancies characterised by proliferation of one or more cells of the myeloid lineage. The molecular<br/>investigation of MPN was revolutionized in 2005 by the finding that approximately 95% of cases …
