N,N-Dimethyl-D-erythro-sphingosine (DMS) competitively inhibits sphingosine kinase (SPHK) and has been widely used to assess the role of SPHK during cellular events, including motility, proliferation, and differentiation. In the present study, the effect of DMS on the differentiation of bone marrow macrophages (BMMs) to osteoclasts was investigated. When the osteoclast precursor cells were trea...

Intertidal sediments usually contain a high amount of dimethylsulfoniopropionate (DMSP) and therefore represent environments with a potentially high emission of dimethylsulfide (DMS). However, knowledge on production and release of DMSP in intertidal sediments is limited. Here, we present data on the diel variation of the total DMS and DMSP content (DMS[P]total) and the DMS(P) concentration in ...

We found that the atomic-concentration-ratio of carbon to silicon (C/Si ratio) in carbide (SiC) films formed by thermal chemical vapor deposition (CVD) was much greater than 1 when source gas for CVD dimethylsilane (DMS). Thus, we tried change carbon-inclusion levels film injecting some ion beams into a depositing SiC during process with DMS. Three beams, i.e., Si+, SiCH5+, or C+ ions were inje...

Due to the significance of multiculturalism in politics, and the central role linguistic devices play in organizing the political discourse, this text-based qualitative study was carried out to compare political interviews in the Iranian and English contexts to find out the probable similarities and differences in the use of discourse markers (DMs) between the two cultures. To this end, three s...

Concern about NO− 3 leaching and groundwater pollution from corn monoculture has prompted an investigation of alternative production systems that reduce leaching. It is hypothesized that both intercropping and water-table control could increase N uptake and reduce the quantity of N that might be lost due to leaching. This study compared corn (Zea mays L.) with annual Italian rye-grass (Lolium m...

where A and B are called the lower frame bound and upper frame bound, respectively. In particular, when A= B = 1, we say that {hk}k∈Z is a (normalized) tight frame in H.
