The generalized Poisson regression model has been used to dispersed count data. It is a good competitor the negative binomial when data over-dispersed. Zero-inflated and zero-inflated models have proposed for situations where generating process results into too many zeros. In this paper, we propose (ZIGP) domestic violence with Estimation of parameters using method maximum likelihood provided. A score test presented whether number zeros large adequately fit

Background Resveratrol, a naturally occurring phytopolyphenol compound, has attracted extensive interest in recent years because of its diverse pharmacological characteristics. Although resveratrol possesses chemopreventive properties against several cancers, the molecular mechanisms by which it inhibits cell growth and induces apoptosis have not been clearly understood. The present study was carried out to examine whether PI3K/AKT/FOXO pathway mediates biological effects resveratrol....

Cancer stem cells (CSCs) play major roles in cancer initiation, progression, and metastasis. It is evident from growing reports that PI3K/Akt/mTOR Sonic Hedgehog (Shh) signaling pathways are aberrantly reactivated pancreatic CSCs. Here, we examined the efficacy of combining NVP-LDE-225 (PI3K/mTOR inhibitor) NVP-BEZ-235 (Smoothened on CSCs characteristics, microRNA regulatory network, tumor growth. co-operated with inhibiting CSC's characteristics growth mice by acting at level Gli....

Ovarian cancer is the second most common gynecological and leading cause of death in United States. In this article we review diagnosis current management epithelial ovarian which accounts for over 95 percent malignancies. We will present various theories about potential origin discuss genetic anomalies syndromes that may cancers with emphasis on Breast type 1/2 mutations. The pathology pathogenesis carcinoma also be presented. Lastly, provide a comprehensive overview treatment strategies...

Background Resveratrol (3, 4′, 5 tri-hydroxystilbene), a naturally occurring polyphenol, exhibits anti-inflammatory, antioxidant, cardioprotective and antitumor activities. We have recently shown that resveratrol can enhance the apoptosis-inducing potential of TRAIL in prostate cancer cells through multiple mechanisms vitro. Therefore, present study was designed to validate whether xenograft model cancer. Methodology/Principal Findings alone inhibited growth PC-3 xenografts nude mice by...

MicroRNAs (miRNA) have potential prognostic value for colorectal cancers; however, their based on patient race/ethnicity and pathologic stage has not been determined. The goal was to ascertain the of 5 miRNAs with increased expression in cancers African American (black) non-Hispanic Caucasian (white) patients.TaqMan quantitative real-time PCR used quantify miR-20a, miR-21, miR-106a, miR-181b, miR-203 paired normal tumor cancer archival tissues collected from 106 black 239 white patients....

N-Myc Interactor is an inducible protein whose expression compromised in advanced stage breast cancer. Downregulation of NMI, a gatekeeper epithelial phenotype, tumors promotes mesenchymal, invasive and metastatic phenotype the cancer cells. Thus mechanisms that regulate NMI are potential interest for understanding etiology tumor progression metastasis. Web based prediction algorithms were used to identify miRNAs potentially target transcript. Luciferase reporter assays western blot analysis...
