Systems (PACS) have evolved over the last few years. Twisted pairs and coaxial cable networks have been used for image transfer at low data rates. Second generation PACS networks use fiber optic communications at speeds up to 140 Mbps. In this paper, the need for integrated voice, data, and image communications and network rates over 200 Mbps is presented. A high speed fiber optic network for integrated PACS services has been design and simulated in the Computer Engineering Research Laboratory at the University of Arizona. This paper summarizes the characteristics and protocols of this network. The network represents a high performance application for local PACS environments and its implementation is technically feasible now.

It proposed that the cardiovascular effects of estrogen are mediated, at least in part, through the ability of estrogen to increase nitric oxide (NO) synthesis. This study investigated the effect of estrogen on serum NO concentrations in normotensive and deoxycorticostrone acetate (DOCA) Salt hypertensive ovariectomized rats. Forty-eight female rats were ovariectomized and randomly divided into six groups. Hypertension was induced by DOCA Salt method. DOCA was injected 30 mg/kg of body weight subcutaneously, twice a week with NaCl 1% instead of tap water for drinking throughout the treatment period. Estradiol valerate (Es) was injected i.m. once a week. The groups were as follows: (2) DOCA (4 weeks) and DOCA+Es (6 weeks), (22) DOCA (10 weeks), (222) normal saline (N/S) (4 weeks)+Es (6 weeks), (2V) N/S (10 weeks), (V) DOCA (4 weeks), and (V2) N/S (4 weeks). Serum NO concentrations were measured in groups 1, 3 and 4 before and after treatment. Other groups were used as control. Results showed that in normotensive animals, serum NO concentrations were increased after estrogen treatment significantly (90.20 +/- 18.67 vs. 19.11 +/- 1.78 micromol/l) (p < 0.05). Also, estrogen increased serum NO concentrations in DOCA Salt hypertensive rats (73.54 +/- 22.55 vs. 36.94 +/- 10.73 micromol/l) (p = 0.06). Estrogen can increase serum NO concentrations in normotensive and DOCA Salt hypertensive animals and it may be important in cardiovascular effects of estrogen.

This concept refers to software components as well as processing capacity and any other resources that can be offered through the Internet. There is a need for a third party that make registering and searching services easy and feasible. Web Service Technology (WST) is one of those current solutions to the Internet of services that has attracted much attention. Registering and searching of the services are feasible by use of Service Directory. The current structure of WST that is mainly based on UDDI suffers from some structural shortcomings. From a structural point of view, service directory is implemented as a centralized node that is a performance bottleneck and single point of failure. In this paper, shortcomings of the current UDDI structure are analyzed through some quantitative experiments. Then, in order to address this shortcoming, a structure is presented by interlinking services using some sort of semantic relation that can be established between WST entities. Different aspects of structure and its performance enhancement are shown through experiments.
