Sacral nerve stimulation for neuromodulation of the lower urinary tract.

Sacral neuromodulation (SNM) has become a standard treatment option for patients suffering from urinary urge incontinence, urgency-frequency, and/or nonobstructive urinary retention refractory to conservative and pharmacologic treatment. Since its initial development, the manufacturer of InterStim therapy (Medtronic, Inc., Minneapolis, MN, USA), has introduced technical modifications, while surgeons and researchers have adapted and published various innovations and alterations of the implantation technique.

Possible prevention and treatment of prostate cancer by exercise.

Exercise and physical activity have been linked to the prevention of certain types of cancer such as colon and breast. As prostate cancer is the most common malignancy diagnosed in the male population, there is obvious interest in determining a possible effect of exercise on disease prevention and improvement of disease-related outcomes. Thus far, data has been conflicting and there has been no clear determination of prostate cancer prevention through exercise.

Long-term neurodevelopmental outcomes in children born with gastroschisis: the tiebreaker.

Purpose: We evaluated 2-year neurodevelopmental outcomes in children with gastroschisis.

Methods: We reviewed the records of children with gastroschisis treated between August 2001 and July 2008. Children discharged from the neonatal intensive care unit were referred to the state-sponsored Developmental Tracking Infant Progress Statewide (TIPS) program.

Bayley Scales of Infant Development Screening Test-Gross Motor Subtest: efficacy in determining need for services.

Purpose: To identify the efficacy of the Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III), Screening Test-Gross Motor Subtest (GMS) in identifying infants who are accepted for early intervention services.

Methods: This retrospective study included 93 infants with a neonatal intensive care experience who participated in a 6-month developmental assessment follow-up visit. All infants were examined using the BSID-III Screening Test-GMS and the Alberta Infant Motor Scale.

Corn-derived carbohydrate inositol hexaphosphate inhibits Barrett's adenocarcinoma growth by pro-apoptotic mechanisms.

Inositol hexaphosphate (IP6) is a naturally occurring polyphosphorylated carbohydrate that is found in food sources high in fiber content. IP6 has been reported to have significant inhibitory effects against a variety of primary tumors. We hypothesized that IP6 would inhibit the cell growth rate of Barrett's adenocarcinoma in vitro.

Keyhole limpet hemocyanin: an effective adjunct against melanoma in vivo.

Background: We have previously demonstrated the potent in vitro antiproliferative effects of keyhole limpet hemocyanin (KLH) against melanoma. Our prior studies directed us to hypothesize that KLH would be effective in vivo against melanoma, alone and in combination with conventional immunotherapy.

Methods: Mice were inoculated with 2 x 10(7) HTB68 cells and randomized to 6 groups.

Dietary influence on pancreatic cancer growth by catechin and inositol hexaphosphate.

Introduction: Pancreatic cancer is an extremely virulent form of cancer with few effective treatments. Catechin and inositol hexaphosphate (IP6), two naturally occurring molecules found in green tea and high-fiber foods, respectively, are compounds that have been shown to demonstrate anti-proliferative effects when administered as single therapeutic agents against a number of cancers. We hypothesized that, alone and in combination, IP6 and catechin would be effective against pancreatic cancer.

Keyhole limpet hemocyanin potentiates standard immunotherapy for melanoma.

Introduction: Our hypothesis was that keyhole limpet hemocyanin (KLH) would augment the effects of standard immunotherapies for melanoma including interferon-alpha (AIFN) and interleukin (IL)-2.

Peptide YY reverses TNF-alpha induced transcription factor binding of interferon regulatory factor-1 and p53 in pancreatic acinar cells.

Background: Cytokine activation in the pancreatitis induces local and systemic cellular damage. Transcription factors interferon regulatory factor-1 (IRF-1) and the tumor suppressor gene p53 collaborate to enhance p21 related cell cycle regulation during pathological disease progression. However, little is known about their role in the pancreas after cytokine challenge.

Additive effects of Cox-1 and Cox-2 inhibition on breast cancer in vitro.

We hypothesized that combined treatment with Cox-1 and Cox-2 specific inhibitiors would exhibit synergistic effects against breast cancer in vitro. Two human breast cancer cell lines (HTB26, MCF-7) were treated with catechin (Cox-1 inhibitor) or NS398 (Cox-2 inhibitor) at 100 microM as both single and combined treatments. Reductions in cell growth were observed in both cell lines at 24 and 72 h in both single and combined treatments (p<0.

Inositol hexaphosphate (IP6) inhibits cellular proliferation in melanoma.

Background: Inositol Hexaphosphate (IP6) is a naturally occurring polyphosphorylated carbohydrate found in food sources high in fiber content. We have previously reported IP6 to have significant inhibitory effects against pancreatic cancer in vitro. We hypothesized that the IP6 would significantly inhibit cell growth of cutaneous melanoma in vitro.

Inhibition of melanoma growth by hemocyanin occurs via early apoptotic pathways.

Background: We hypothesized that keyhole limpet hemocyanin (KLH) would reduce cellular proliferation and effect apoptosis of melanoma cell lines in vitro.

Methods: Two human melanoma cell lines (HTB68 and HTB72) were subjected to a dose-response treatment regimen of KLH (0.4 microg to 100 microg/well).

MAPK and PI3K inhibition reduces proliferation of Barrett's adenocarcinoma in vitro.

Background: Esophageal adenocarcinoma often arises from Barrett's esophagus. Mitogen-activated protein kinase (MAPK) and phosphatidylinositol 3-kinase (PI3K) play critical roles in cell survival. We hypothesized that inhibition of these pathways in Barrett's adenocarcinoma would decrease cell proliferation and alter apoptosis in vitro.

Inositol hexaphosphate (IP6): a novel treatment for pancreatic cancer.

Background: Inositol hexaphosphate (IP6) is a naturally occurring polyphosphorylated carbohydrate found in food sources high in fiber content. IP6 has been reported to have significant inhibitory effects against a variety of primary tumors including breast and colon. The effects of IP6 have not been evaluated in pancreatic cancer.

In vitro effects of keyhole limpet hemocyanin in breast and pancreatic cancer in regards to cell growth, cytokine production, and apoptosis.

Background: We have previously shown the inhibitory effects of keyhole limpet hemocyanin (KLH) against breast and pancreatic cancer in vitro. We hypothesize that its actions in breast and pancreas cancer cells are via apoptotic or cytokine pathways.

Methods: Two breast cancer cell lines, ZR75-1 and MCF-7, and one pancreas cancer cell line, PANC-1, were treated with KLH at 500 mug, 250 mug, and 250 ng/mL.

In vitro effects of pentosan polysulfate against malignant breast cells.

Background: Pentosan polysulfate (Elmiron); (Alza Pharmaceuticals, Mountain View, CA) is the only Food and Drug Administration-approved oral therapy for interstitial cystitis (IC). Women with IC and breast cancer are often in the same age range; therefore, we hypothesize that pentosan polysulfate may also have a therapeutic effect on breast cancer cells in vitro.

Methods: Breast cancer lines MCF-7, ZR75-1, and HTB26 were treated with pentosan polysulfate at various concentrations.

Peptide YY inhibits the growth of Barrett's esophageal adenocarcinoma in vitro.

Background: Peptide YY (PYY) is an endogenous gut hormone that inhibits the growth of certain cancers. Adenocarcinoma of the esophagus usually arises from Barrett's esophagus. We hypothesized that treatment of Barrett's adenocarcinoma with PYY would result in decreased proliferation.

Synergistic effects of Cox-1 and -2 inhibition on bladder and prostate cancer in vitro.

Background: We hypothesized that combined treatment with cyclooxygenase (Cox)-1 (catechin) and Cox-2 (NS398)-specific inhibitors would reduce cellular proliferation synergistically in genitourinary cancer.

Methods: Bladder (T24 and TCCSUP) and prostate (DU145, LnCaP, and PC3) cancer cell lines were treated with catechin and NS398 at a dose of 100 mumol/L as single and combined treatments. Viability was measured by MTT assay at 24 and 72 hours.

COX-2 inhibition and cancer: experimental findings and clinical correlates.

To test our hypothesis that Cyclooyxgenase-2 (COX-2) inhibitors would stop the growth of breast and prostate cancer cells in vitro, two breast (MCF-7, ZR75-1) and two prostate cancer cell lines (PC-3, DU145) were treated with rofecoxib (Vioxx) or NS398. Cell growth was measured by MTT at 24 and 72 hours. Statistical analysis was performed by ANOVA.

Antiproliferative and apoptotic effects of rofecoxib on esophageal cancer in vitro(1).

Background: The incidence of Barrett's adenocarcinoma has increased dramatically in the United States, whereas squamous cell carcinoma of the esophagus remains a worldwide problem. Cyclooxygenase (COX)-2 may play an important role in gastrointestinal carcinogenesis and is overexpressed in both Barrett's metaplasia and adenocarcinoma. We hypothesized that a selective and commercially available COX-2 inhibitor, rofecoxib (Vioxx), would inhibit growth of Barrett's adenocarcinoma and squamous cell carcinoma of the esophagus by apoptotic pathways.

Keyhole limpet hemocyanin, a novel immune stimulant with promising anticancer activity in Barrett's esophageal adenocarcinoma.

Background: Keyhole limpet hemocyanin (KLH) is a recently described immune stimulant and hapten carrier derived from a circulating glycoprotein of the marine mollusk Megathura crenulata. We previously reported that KLH has significant antiproliferative effects in vitro against breast, pancreas, and prostate cancers. We hypothesized that KLH would be effective against Barrett's esophageal adenocarcinoma in an in vitro model.

Use of Immunomagnetic Capture on Beads to Recover Listeria from Environmental Samples.

Current methods of Listeria detection require days to complete and may fail to detect Listeria in some samples. In contrast, capture of Listeria on microscopic immunomagnetic beads reduces test time to 24 h and improves sensitivity. In this approach, which eliminates enrichment, samples are mixed with immunomagnetic beads coated with anti- Listeria antibodies.
