Efficacy of an Internet-based depression intervention to improve rates of treatment in adolescent mothers.

Approximately 400,000 adolescents give birth in the USA annually. Although one-half experience depressive symptoms, less than 25% comply with referrals for depression evaluation and treatment. The current study tested the effectiveness of an Internet-based depression intervention on seeking depression treatment.

NADPH oxidase NOX4 supports renal tumorigenesis by promoting the expression and nuclear accumulation of HIF2α.

Most sporadically occurring renal tumors include a functional loss of the tumor suppressor von Hippel Lindau (VHL). Development of VHL-deficient renal cell carcinoma (RCC) relies upon activation of the hypoxia-inducible factor-2α (HIF2α), a master transcriptional regulator of genes that drive diverse processes, including angiogenesis, proliferation, and anaerobic metabolism. In determining the critical functions for HIF2α expression in RCC cells, the NADPH oxidase NOX4 has been identified, but the pathogenic contributions of NOX4 to RCC have not been evaluated directly.

Aberrant methylation and loss of CADM2 tumor suppressor expression is associated with human renal cell carcinoma tumor progression.

Cell adhesion molecules (CADMs) comprise a protein family whose functions include maintenance of cell polarity and tumor suppression. In this report, we show that the CADM2 gene is repressed in human clear renal cell carcinoma by DNA promoter hypermethylation and/or loss of heterozygosity. Moreover, the loss of CADM2 expression is associated with a higher tumor pathology stage (p<0.

Deficiency of DNA repair nuclease ERCC1-XPF promotes prostate cancer progression in a tissue recombination model.

Background: The excision repair cross complementing (ERCC1) gene product plays a vital role in the nucleotide excision repair (NER) and DNA interstrand crosslink repair pathways, which protect the genome from mutations and chromosomal aberrations, respectively. Genetic deletion of Ercc1 in the mouse causes dramatically accelerated aging. We examined the effect of Ercc1 deletion in the development of prostate cancer in a prostate recapitulation model as Ercc1 deficient mice die within four weeks of birth.

Measurement of the thickness and volume of adherent cells using transmission-through-dye microscopy.

Cell volume is one of the basic characteristics of a cell and is being extensively studied in relationship to a variety of processes, such as proliferation, apoptosis, fertility, or locomotion. At the same time, its measurement under a microscope has not been well developed. The method we propose uses negative transmission contrast rendered to cells by a strongly absorbing dye present in the extracellular medium.

Analysis of gene expression in prostate cancer epithelial and interstitial stromal cells using laser capture microdissection.

Background: The prostate gland represents a multifaceted system in which prostate epithelia and stroma have distinct physiological roles. To understand the interaction between stroma and glandular epithelia, it is essential to delineate the gene expression profiles of these two tissue types in prostate cancer. Most studies have compared tumor and normal samples by performing global expression analysis using a mixture of cell populations.

Undressing "health fashion": an examination of health-cause clothing and accessories.

Today, fashion items such as rubber wristbands in various colors, pink ribbons, and red dresses represent different health-related causes and can be seen frequently across demographic groups. Complete with pithy slogans (e.g.

Development of a telehealth intervention for head and neck cancer patients.

Treatment for head and neck cancer precipitates a myriad of distressing symptoms. Patients may be isolated both physically and socially and may lack the self-efficacy to report problems and participate as partners in their care. The goal of this project was to design a telehealth intervention to address such isolation, develop patient self-efficacy, and improve symptom management during the treatment experience.
