We examine reverse mergers (RMs) in the biotechnology industry and find that, when compared to initial public offerings (IPOs), RMs are smaller, have significantly lower market valuations relative to size, and generally invest less. We also find that RMs exhibit positive abnormal returns on the announcement date and throughout the first year after the RM event. In looking at liquidity measures,...

We present applications of variational – wavelet approach to nonlinear (rational) rms envelope dynamics. We have the solution as a multiresolution (multiscales) expansion in the base of compactly supported wavelet basis.

Rhabdomyosarcoma (RMS) is the most common soft-tissue sarcoma of infancy and although therapy has improved over the years, mortality is still fairly high. The establishment of new treatments has been hampered by the limited knowledge of the molecular mechanisms driving development of RMS. One characteristic of cancer cells is aberrant DNA methylation, which could lead to silencing of tumor supp...

BACKGROUND The prognosis of rhabdomyosarcoma (RMS) in children and adolescents has improved since the introduction of multi-agent chemotherapy. However, outcome data of adults with RMS are scarce. This multicenter retrospective study investigated the effect of age on outcome of RMS. PATIENTS AND METHODS Data were collected from three Dutch University Medical Centers between 1977-2009. The eff...

R&D investment drives productivity growth. Therefore, its uctuations over the business cycle a ect long-run dynamics. I show that taking into account the size distribution of innovating rms generates new insights on this link. I write an endogenous growth model with heterogeneous rms assuming, in line with empirical evidence, that small rms have a relatively higher innovation capacity than larg...

Rhabdomyosarcoma (RMS) is an aggressive childhood soft tissue tumor, which exists in oncoprotein PAX-FOXO1 fusion positive and fusion negative subtypes, with the fusion-positive RMS being characterized by a more aggressive clinical behavior. Exosomes are small membranous vesicles secreted into body fluids by multiple cell types, including tumor cells, and have been implicated in metastatic prog...

dear editor:   we thank dr asadi amoli for her interest in our article. 1 dr asadi amoli pointed out that specific and sensitive rhabdomyosarcoma (rms) markers should be investigated in our case. 2 we agree with dr asadi amoli ’s opinion and are sorry that the results of pathology examination and myogenin (myf-4) staining studied in a local hospital were not provided in our case report.   an ex...
