The soluble members of the three-finger protein superfamily all share a relatively simple 'three-finger' structure, yet perform radically different functions. Plethodontid modulating factor (PMF), a pheromone protein produced by the lungless salamander, Plethodon shermani, is a new and unusual member of this group. It affects female receptivity when delivered to the female's nares during courts...

Clinical and laboratory features of 642 consecutive Chinese subjects with primary myelofibrosis (PMF) were analyzed and compared with those of 1054 predominately white subjects with PMF. Chinese subjects were significantly younger, fewer had constitutional symptoms, and fewer had a palpable spleen or liver. Anemia, in contrast, was significantly more common in Chinese as was an increased white ...

BACKGROUND Despite insights into the genetic basis of Philadelphia-negative myeloproliferative neoplasms (Ph-negative MPNs), a significant proportion of essential thrombocythemia (ET) and primary myelofibrosis (PMF) patients present with no known MPN disease alleles. There were no previous studies investigating the impact of ASXL1 mutations in Ph-negative MPNs in Turkey. In the current study, w...

A model eukaryotic cell system was used to explore the effect of a weak pulsed magnetic field (PMF) on time-varying physiological parameters. Dictyostelium discoideum cells (V12 strain) were exposed to a pulsed magnetic field (PMF) of flux density 0.4 mT, generated via air-cored coils in trains of 2 ms pulses gated at 20 ms. This signal is similar to those used to treat non-uniting fractures. S...

OBJECTIVES To explore whether the inhalation of coal mine dust increases the risk of premature death in miners, a survival analysis was conducted in a cohort of 2738 patients with simple pneumoconiosis in the Huai-Bei coal mine, in China. METHODS Age specific mortalities were calculated by disease severity in terms of pneumoconiotic category with the life table method. The progressions from s...

Primary myelofibrosis (PMF) and polycythemia vera (PV) are chronic myeloproliferative neoplasms. PMF and, to a lesser degree, PV are characterized by constitutive mobilization of hematopoietic stem cells (HSC) and progenitor cells (HPC) into the peripheral blood (PB). The interaction between the chemokine CXCL12 and its receptor CXCR4 plays a pivotal role in determining the trafficking of CD34(...

introduction : myeloproliferative neoplasms (mpns) are a group of clonal malignant hematologic disease, where the main and common members are; polycythemia vera (pv), primary myelofibrosis (pmf), and essential thrombocytosis (et). these group of diseases are able to be transformed into each other. methods:   this cross sectional study conducted the evaluation of jak2v161f mutation in dna in per...

Data gathered since 1953 concerning more than 30,000 coalminers while employed at 24 collieries in England, Scotland, and Wales have been used to study the incidence of progressive massive fibrosis (PMF) in working coalminers. Results refer to 52,264 approximately five year intervals when the miners were at risk of an attack of PMF. One objective of the present study was to describe how the fiv...

BACKGROUND Platysma myocutaneous flap (PMF) is a generally used technique for defect reconstruction after an oral cancer resection. The aim of the study is to present our experience using vertical PMF that sacrificed the facial artery and vein for intraoral reconstruction. METHODS A retrospective review of the medical records of 54 patients who underwent vertical PMF that sacrificed the facia...

We experimentally investigated a simple and new technique for the fabrication of micro-ridge long-period gratings (MRLPGs) based on polarization-maintaining fibers (PMFs). The cladding region of the PMFs was etched periodically using a wet etching technique resulting in the periodic formation of micro-ridges on the surface of the PMF. The PMF-based MRLPGs has two resonant peaks because of the b...
