Interleukin-8 (IL-8) and the structurally related cytokines neutrophil-activating peptide-2 (NAP-2) and GRO alpha are powerful chemotactic agents for human neutrophils. Although these three chemokines act by binding to overlapping but not identical receptor subsets, the data available to date have stressed the similarities in their mechanisms of action. The present studies were undertaken to fu...

Background: Chemokines, proteins that operate within the body's immune system, play numerous roles in menstruation, bacterial infection, implantation of embryos, and the maintenance of early pregnancy. They are also strongly related to the pathogenesis of endometriosis. Materials and Methods: This is review article that were indentifical by computer search of MEDLINE (1984- 2013). Results:...

A transient X-ray source, GRO J1008[57, was discovered by the Burst and Transient Source Experiment (BATSE) on board the Compton Gamma Ray Observatory (CGRO) in 1993 July. It reached a maximum intensity of about 1.4 times that of the Crab, in the 20È60 keV energy band. Pulsations in the X-ray intensity were detected at a period of 93.5 s. It has subsequently been determined to be a member of th...

The sterile insect technique (SIT) is widely used in integrated programs against tephritid fruit fly pests, particularly the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae). Unfortunately, the mass-rearing procedures inherent to the SIT often lead to a reduction in the mating ability of the released males. One potential solution involves the prerelease exposure of...

We tabulate the luminosities of the soft-to-hard state transitions of all X-ray binaries for which there exist good X-ray flux measurements at the time of the transition, good distance estimates, and good mass estimates for the compact star. We show that the state transition luminosities are at about 1-4% of the Eddington rate, markedly smaller than those typically quoted in the literature, wit...

This paper proposes a high frequency ring oscillator with low power consumption. The proposed ring oscillator is based on Gated Ring Oscillator (GRO) by applying boot strap technique. Simulation results indicate that the FoM (Power Consumption /Oscillation Frequency) of the proposed ring oscillator is greater than that of the conventional ring oscillator. Figure 1 shows delay element using boot...

GRO J2058+42, a transient 198 second x-ray pulsar, was discovered by the Burst and Transient Source Experiment (BATSE) on the Compton Gamma-Ray Observatory (CGRO), during a “giant” outburst in 1995 September-October. The total flux peaked at about 300 mCrab (20-50 keV) as measured by Earth occultation. The pulse period decreased from 198 s to 196 s during the 46-day outburst. The pulse shape ev...

We present further observational evidence of the effects of a centrifugal barrier in GRO J1744-28, based on continued monitoring of the source with RXTE.
