BACKGROUND AND PURPOSE Ecchordosis physaliphora (EP), found in about 2% of autopsies, is a clinically inconspicuous notochordal remnant appearing at the dorsal wall of the clivus. To our knowledge, a systematic review of its MR features does not exist. The aim of this study was to describe the MR imaging findings of incidentally found retroclival EP with special respect to its differentiation f...

PURPOSE To assess the value of oral effervescent powder (EP) for evaluation of esophageal distension, and for detection and staging of esophageal cancer with contrast-enhanced CT. MATERIALS AND METHODS 84 patients without esophageal pathology and 52 patients with histological confirmed diagnosis of esophageal cancer were included in this prospective IRB-approved study. Half of the patients in...

Objective Many previous studies have reported that pain symptoms can lead to significant brain function and anatomical changes, whereas the intrinsic brain activity changes in acute eye pain (EP) patients remain unknown. Using the amplitude of low-frequency fluctuation (ALFF) method, this study aimed to evaluate the spontaneous brain activity alterations and their relationships with clinical fe...

The concentration of beta-endorphin (B-EP) was measured in 6 trained and 6 untrained cyclists during three intensities of exercise to determine the time course changes of B-EP. B-EP was determined by radioimmunoassay with less than 5% cross reactivity with beta-lipotrophin. A counter-balanced design was used to avoid an order effect from exercise intensity. Resting B-EP values were similar acro...

The aim of the present study was to assess the protective effect of ethyl pyruvate (EP) on sperm quality parameters, testosterone level and malondialdehyde (MDA) in phenylhydrazine (PHZ) treated mice. For this purpose, 32 NMRI mice with the age range of 8 to 10 weeks, weight average 26.0 ± 2.0 g, were randomly divided into four equal groups. The control group (1) received normal saline (0. 1 mL...

PURPOSE The tumor-associated antigen Ep-CAM (epithelial cell adhesion molecule) is overexpressed in colorectal carcinoma (CRC). The aim of the present study was to evaluate and compare the safety and immunogenicity of a recombinant Ep-CAM protein and a human anti-idiotypic antibody (anti-Id) mimicking Ep-CAM. EXPERIMENTAL DESIGN Patients with resected American Joint Committee on Cancer stages...

Endogenous pyrogen (EP) 1 was first described by Beeson (1) in saline extracts of rabbit peritoneal exudate cells. These cells were >95% neutrophils, and it was assumed that neutrophils were the source of the pyrogen (1). A series of studies over the last 30 yr has established that EP is the common mediator of almost all febrile states that are not attributable to disorders of the thermoregulat...

In this section we give all the necessary details to implement the EP algorithm [1] for the GPCconf method described in the main manuscript. We show how to compute the EP posterior approximation from the product of all approximate factors and how to implement the EP updates to refine each approximate factor. We also show how to compute the EP approximation of the marginal likelihood and its gra...

PGE(2) is an important cyclooxygenase product that modulates airway inflammatory and smooth muscle responses. Signal transduction is mediated by four EP receptor subtypes that cause distinct effects on cell metabolism. To determine the role of EP(2) receptor activation, we produced a mouse lacking the EP(2) receptor by targeted gene disruption. The effect of aerosolized PGE(2) and other agonist...
