We report the discovery of nearly coherent oscillations with a frequency of ∼ 567 Hz during type-I X-ray bursts from the X-ray transient and eclipsing binary X 1658–298. If these oscillations are directly related to the neutron star rotation then the spin period of the neutron star in X 1658–298 is ∼1.8 ms. The oscillations can be present during the rise or decay phase of the bursts. Oscillatio...
Acute pancreatitis is one of the most common surgical disease, and thus cause of hospitalization. Incidence and etiology of this condition demonstrates large regional differences. This situation is a substantial financial burden forhospital district, and changes in organization structure and funding medical service should be taken under consideration.The aim of the study was to record the epide...
The mechanism by which the geranylgeranyltransferase I inhibitor GGTI-298 and the farnesyltransferase inhibitor FTI-277 inhibit human tumor growth is not known. Herein, we demonstrate that in the human lung adenocarcinoma A549 cells, GGTI-298 induced a G1-G0 block whereas FTI-277 induced an enrichment in the G2-M phase of the cell cycle. Although FTI-277, GGTI-298, and compactin inhibited A549 ...
Human T-cell leukemia virus type-1 (HTLV-1) is the etiological agent of adult T-cell leukemia (ATL), an aggressive and highly chemoresistant malignancy. Rho family GTPases regulate multiple signaling pathways in tumorigenesis: cytoskeletal organization, transcription, cell cycle progression, and cell proliferation. Geranylgeranylation of Rho family GTPases is essential for cell membrane localiz...
Cell development is regulated by a complex network of mRNA-encoded proteins and microRNAs, all funnelling onto the modulation of self-renewal or differentiation genes. How intragenic microRNAs and their host genes are transcriptionally coregulated and their functional relationships for the control of neural stem cells (NSCs) are poorly understood. We propose here the intragenic miR-326 and its ...
Comments on Multiparameter Estimation in Truncated Power Series Distributions under the Stein's Loss
This comment is to show that Theorem3.3 of Dey and Chung (1991) (Multiparameter estimation intruncated power series distributions under the Stein's loss.emph{Commun. Statist.-Theory Meth.,} {bf 20}, 309-326) may giveus misleading results. Analytically and through simulation, weshow that the Theorem does not improve the given estimator.
