IL-33 is a member of the IL-1 family of cytokines, and no study has been performed to address its direct anti-tumor effect. This study is designed to investigate whether IL-33 has any direct effect on pancreatic cancer. Clonogenic survival assay, immunohistochemistry, TUNEL staining, proliferation, caspase-3 activity kits and RT-PCR were used to evaluate the effects of IL-33 on cell survival, proliferation and apoptosis of a pancreatic cancer cell line, MIA PaCa-2.

Methods: We examined the effects of IL-9 on proliferation and apoptosis in four human melanoma cell lines, HTB-65, HTB-72, CRL-11147, and SK-Mel-5.
Interleukin-35 (IL-35), an IL-12 cytokine family member, mediates the immune inhibitory function of regulatory T cells (Treg). We assayed the presence of IL-35 in paraffin-embedded human pancreas cancer (PCAN) and unexpectedly found IL-35 was expressed mainly by epithelial derived PCAN cells, but not by Treg. We further examined the expression and effect of exogenous IL-35 in human PCAN cell lines and found IL-35 promoted growth and inhibited apoptosis in PCAN cell lines.

Here, we examined the radiosensitizing effect of hydrogen peroxide (H(2)O(2)) on a radioresistant melanoma cell line, HTB-65. We found that H(2)O(2) synergized with RT to inhibit melanoma cell proliferation and promote apoptosis.

Clinical use of XRT for melanoma is often limited by extent of disease and the relative radioresistance of melanoma may limit the effectiveness of XRT. Our group and others have previously shown that resveratrol (RSV) enhances radiation sensitivity in radioresistant prostate cancer cell lines.

Methods: Total RNA and protein were extracted from APA, 12 NH, and 15 NAG tissues. mRNA and protein expressions of CPY17 were examined by real-time polymerase chain reaction (PCR) and Western blot analysis.
Perforin and granzyme B are expressed primarily by activated lymphocytes (cytotoxic T cells, natural killer cells, and natural killer T cells) and function together to induce apoptosis of target cells. Typically, these proteins are not expressed in tumor cells. In the present study, we established the constitutive expression of perforin and granzyme B by the PC-3 and DU145 prostate cancer (PCA) cell lines with reverse transcription polymerase chain reaction, immunohistochemistry, Western blot, or a combination of techniques.

We hypothesized that endogenous NO bioavailability would be reduced in obese/diabetic mouse hearts due to enhanced superoxide anion production, and that coronary smooth muscle responses to exogenous NO would be reduced.
Methods: Age-matched, male C57BL/6J mice were fed either a control diet or a high-fat, high-carbohydrate diet.
Study Objective: The purpose of this study is to determine the frequency with which primary care physicians add inhaled corticosteroids to the regimen of asthmatic patients after a visit to the emergency department (ED) among patients not previously prescribed inhaled corticosteroids and to determine the rate at which inhaled corticosteroids prescribed in the ED were continued by primary care physicians.
Methods: We conducted a structured retrospective cohort study using electronic medical record review of consecutive patients aged 6 to 45 years, treated for acute asthma exacerbation (International Classification of Diseases, Ninth Revision code 493.00 through 493.
Although few contemporary studies specifically address paternal adaptation, the theme of paternal estrangement from medical care and from family relationships is pervasive in the psychosocial literature on haemophilia. This estrangement has been shown to have a negative effect on fathers' psychological well-being, marital relationships and the adaptive outcome of their sons who have haemophilia. The goals of this study were to provide contemporary data on the psychosocial adaptation of fathers of boys with haemophilia and to examine specific variables that might influence their adjustment.

This study was designed to investigate the effects of daily dermal application of these chemicals, alone or in combination, on the permeability of the blood-brain barrier (BBB) and blood-testes barrier (BTB) and on sensorimotor performance in male Sprague-Dawley rats. Groups of five rats were treated with a dermal daily dose of 4, 40, or 400 mg/kg DEET in ethanol or 0.

Health care is changing rapidly due in part to Diagnostic Related Groups (DRGs), patients becoming consumer-oriented, and the Acquired Immune Deficiency Syndrome (AIDS) crisis. Patients now spend less time in acute care settings and more time recovering in an ambulatory care environment. Patients undergoing bone marrow transplants have a long, stressful, and expensive course of recovery.

A significant relationship was found between the occurrence of the antibody in Nigerian sera and the presence of high levels of malaria antibody and of high levels of IgM. Speckled antinuclear factor was also found in the sera of CBA mice infected with .

Rheumatoid factor and autoantibodies were found no more frequently in patients with rheumatoid arthritis than in controls. These findings confirm the clinical impression that Nigerian patients with polyarthritis satisfying the criteria for a diagnosis of rheumatoid arthritis differ from Caucasian patients with the disease in a number of important respects.
