Purpose: High levels of serum VEGF have been reported in many types of cancers, especially in the metastatic stage. The aim of this study was to examine the potential of VEGF serum level as a tumor marker for metastases in uveal melanoma (UM) patients.
Materials And Methods: Levels of serum VEGF were analyzed by ELISA for 23 UM patients (none of whom developed metastases within 5 years from diagnosis) at the time of diagnosis, soon after treatment, and 3 years later, and compared with serum VEGF levels of 39 metastatic patients, 58 10-year disease-free (10yDF) patients, and 23 healthy subjects.
Aim: To compare trends in liver function test (LFT) levels over consecutive visits before detection of liver metastasis (LM) from uveal melanoma (UM) with such trends in the serum tumor markers S-100β, melanoma inhibitory activity (MIA), osteopontin (OPN), and tissue polypeptide-specific antigen (TPS).
Patients And Methods: Blood was drawn from 32 patients with metastatic UM and 43 disease-free (DF) patients semi-annually for levels of S-100β, MIA, OPN, and TPS. Abdominal ultrasonography (US) and LFTs were used to detect LM.
Aim: To examine the kinetics of the tumor marker levels: osteopontin (OPN), S-100β, melanoma inhibitory activity (MIA) and tissue polypeptide-specific antigen (TPS), and to evaluate their potential for predicting earlier liver metastasis in patients with uveal melanoma (UM).
Patients And Methods: Forty-three UM patients who remained disease-free (DF) for at least 10 years, 32 patients with metastatic UM and 53 healthy controls were enrolled. Median and mean levels of the tumor markers OPN, S-100β, MIA and TPS at the time periods of 0-6, 6-12, 12-18, 18-24 and >24 months prior to confirmation of metastasis by liver ultrasound, CT scan and biopsy, served in a box and whiskers analysis and were compared by Students t-test.
Purpose: To develop a method to screen for serum biomarkers of early hepatic metastasis from uveal melanoma.
Methods: Cytokeratin 18 (TPS) was identified from gene expression profiles as protein generated by highly invasive uveal melanoma cells. Sera were collected from two groups of 15 SCID mice 2 weeks after injection of either tissue culture medium or MUM2B human metastatic uveal melanoma cells into the mouse liver.
Background: Osteopontin (OPN) is overexpressed in metastatic uveal melanoma (UM). S-100beta and melanoma-inhibitory activity (MIA) serum levels are elevated in metastatic cutaneous melanoma. The ability of OPN, S-100beta and MIA serum levels to be used as non-invasive markers for detecting metastatic UM was tested.

Purpose: This was a pilot study conducted to examine the expression of osteopontin in uveal melanoma and to determine whether serum osteopontin can be used in detecting metastatic uveal melanoma.
Methods: Osteopontin mRNA was measured in three uveal melanoma cell lines of various invasive potential by real-time PCR. Tissue sections of primary and metastatic uveal melanomas were stained for osteopontin.
Background: Previous studies have shown that PADMA-28, a multicomponent, traditional Tibetan herbal plant preparation possesses a variety of beneficial effects on several experimental models of inflammatory and immune processes, including autoimmune diabetes and autoimmune encephalomyelitis. In humans, PADMA-28 attenuated the symptoms associated with intermittent claudications in atherosclerotic patients.
Objective: To assess the effect of PADMA 28 on the immune system, e.
Objective: To assess the involvement of interleukin-18 (IL-18) in the pathophysiology of severe ovarian hyperstimulation syndrome (OHSS), and study its use as a marker of disease and its correlation to capillary hyperpermeability.
Design: Prospective controlled study.
Setting: An IVF unit in a tertiary medical center.
Background: Some herbal remedies are sold as food additives and are believed to have immune-enhancing properties.
Objectives: To study the effect of five herbal remedies--Sambucol Black Elderberry Extract, Sambucol Active Defense Formula and Sambucol for Kids (with known antiviral properties), Protec and Chizukit N (containing propolis and Echinacea, claimed to be immune enhancers)--on the production of cytokines, one of the main components of the immune system.
Methods: The production of four inflammatory cytokines (interleukin-1 beta, tumor necrosis factor alpha, and IL-6 and IL-8) and one anti-inflammatory cytokine (IL-10) was tested using blood-derived monocytes from 12 healthy donors.
