Recent data provide evidence for an important role of thrombocytes in lymphangiogenesis within human malignant disease. The aim of this study was to investigate the role of thrombocytes in lymphangiogenesis in human esophageal cancer. Perioperative peripheral blood platelet counts (PBPC) were evaluated retrospectively in 320 patients with esophageal cancer, comprising 184 adenocarcinomas (AC), ...

The telecom field has changed accordingly with the emergence of new technologies. This is case market in Saudi Arabia, which expanded 2003 by attracting investors. As a result, became viable [1] . prevalence mobile voice service among population Arabia for that, this...

In a dual-task paradigm, a visual display (T1) containing characters (letters or symbols) was presented first, followed by an auditory signal (T2) at various stimulus-onset asynchronies (SOAs). A speeded response to T2 was required. When the information in T1 had to be recalled later, response times to T2 (RT2) were elevated at short SOAs and decreased as SOA was increased. The effects on RT2 w...

This paper discusses the potential performance of future MIMO-systems. It is shown that for one of the suggested applications for a MIMO-system, as a fibre replacement between the central office and the cabinets, the potential performance increase is below two times the non-MIMO system. Distribution: ETSI STC TM6 working group members Status: For information This contribution has been prepared ...

CONTEXT A pilot study of South Vietnamese ex-political detainees who had been incarcerated in Vietnamese reeducation camps and resettled in the United States disclosed significant mental health problems associated with torture and traumatic head injury (THI). OBJECTIVES To identify structural brain alterations associated with THI and to investigate whether these deficits are associated with p...

Relationships of regional colonic motility to transit in health, constipation, and constipation-predominant irritable bowel syndrome (C-IBS) are poorly characterized. This study aimed to 1) characterize regional differences in colon pressure, 2) relate motor differences in constipation to colon transit, and 3) quantify the role of IBS in altered contractility with constipation. Colon pH and pre...

The present study was carried out to analyze the differences in the activity of hormone stanniocalcin (STC) between male and female fishes of Mastacembelus armatus during their gonadal cycle. A large variation in nuclear diameter of cells of corpuscles of Stannius (CS) were recorded in relation to testicular cycle as well as ovarian cycle which indicates that the cellular activity varied with d...

STUDY OBJECTIVES To evaluate prospectively the ability of two equations that we previously derived to predict maintenance theophylline dosages that provide a serum theophylline concentration (STC) of 8 micrograms/ml, the midtherapeutic range for treating apnea of prematurity; and to determine the number of further dosage adjustments and STC determinations required to achieve the target concentr...

We describe an automatic event recognition (AER) system based on a three-dimensional spatio-temporal correlator (STC) that combines the techniques of holographic correlation and photon echo based temporal pattern recognition. The STC is shift invariant in space and time. It can be used to recognize rapidly an event (e.g., a short video clip) that may be present in a large video file, and determ...

This paper describes a new speech corpus, STC-TIMIT, and discusses the process of design, development and its distribution through LDC. The STC-TIMIT corpus is derived from the widely used TIMIT corpus by sending it through a real and single telephone channel. TIMIT is phonetically balanced, covers the dialectal diversity in continental USA and has been extensively used as a benchmark for speec...
