Gravitational physics of VLBI experiment conducted on September 8, 2002 and dedicated to measure the speed of gravity is treated in the first post-Newtonian approximation. Explicit speed-of-gravity parameterization is introduced to the Einstein equations to single out the retardation effect associated with the finite speed of gravity in the relativistic time delay of light propagating in the gr...

Nitric oxide (NO(.-)) contributes to vascular collapse in septic shock and regulates inflammation. Here, we demonstrate in lipopolysaccharide (LPS)-stimulated human THP-1 cells and monocytes that NO(.-) regulates interleukin (IL)-8 and tumor necrosis factor alpha (TNF-alpha) by distinct mechanisms. Dibutyryl-cyclic guanosine 5'-monophosphate (cGMP) failed to simulate NO(.-)-induced increases in...

MOTIVATION Phylogenies are increasingly used in all fields of medical and biological research. Moreover, because of the next-generation sequencing revolution, datasets used for conducting phylogenetic analyses grow at an unprecedented pace. RAxML (Randomized Axelerated Maximum Likelihood) is a popular program for phylogenetic analyses of large datasets under maximum likelihood. Since the last R...

PURPOSE To investigate the mechanisms underpinning modifications in glucose homeostasis and insulin sensitivity 24 h after a bout of resistance exercise (RE) with or without protein ingestion. METHODS Twenty-four healthy males were assigned to a control (CON; n = 8), exercise (EX; n = 8) or exercise plus protein condition (EX+PRO; n = 8). Muscle biopsy and blood samples were obtained at rest ...

Survivors from a nationally representative sample of elderly people originally screened in 1985 were reassessed in 1989 and again in 1993. On each occasion respondents were rated as cognitively impaired, borderline impaired or unimpaired (using a brief information/orientation scale), with the validity of these ratings assessed in subsequent clinical interviews. Where follow-up screening was not...

Context. The low-metallicity RV Tauri star MACHO 47.2496.8, recently discovered in the Large Magellanic Cloud, is highly enriched in carbon and heavy elements produced by the slow neutron capture process (s-process), and is most probably a genuine post-C(Ntype) asymptotic giant branch (AGB) star. The intrinsic interpretation of the enrichement is further strengthened by detection of a significa...

On histological examination, mitoses were easily found: 3/10 fields and there were multiple foci of necrosis. On immunohistochemistry, the tumor cells were positive for CD31 and negative for: cytokeratine AE1-AE3, CK7,CK5-6,CK20,EMA,P63,PSA,CDX2,PSO4S, chromogranine A,PS100,CD34,Actine, Desmine, Caldesmone, CD117,DOG1.

We present WFPC2–HST photometry of the resolved stellar population in the post-starburst galaxy NGC 1569. The color-magnitude diagram (CMD) derived in the F439W and F555W photometric bands contains ∼2800 stars with photometric error ≤ 0.2 mag down to mF439, mF555 ≃ 26, and is complete for mF555 ∼ < 23. Adopting the literature distance modulus and reddening, our CMD samples stars more massive th...

In the infinite Post Correspondence Problem an instance (h, g) consists of two morphisms h and g, and the problem is to determine whether or not there exists an infinite word ω such that h(ω) = g(ω). This problem was shown to be undecidable by K. Ruohonen (1985) in general. Recently V. D. Blondel and V. Canterini (Theory Comput. Syst. 36, 231–245, 2003) showed that this problem is undecidable f...

Radial velocities were measured for 5 potential post-AGB stars, two in the globular cluster NGC 1851 and three in the dSph galaxy Ursa Minor. All five potential PAGB stars were found to be radial velocity non-members. Eskridge & Schweitzer 2001 reported proper motion memberships for 3 stars that fall in the post-AGB region of the CM diagram of the UMi system. In 2003 we obtained spectra during ...
