Background: Platinum compounds are the main drugs for treatment of advanced gastric cancer. Previous studies have shown that clinical outcome with platinum-based compounds depends on ERCC1 polymorphisms. The aim of this study was to investigate the frequency of a common polymorphism of ERCC1 gene (C8092A) in Iranian patients with advanced gastric cancer receiving platinum chemotherapy. Materials and Methods: Genetic analysis of the ERCC1 C8092A polymorphism was performed by the PCR - RFLP method using 50 paraffin-embedded tissue specimens. Results: Of the 50 cases, 32% of individuals showed CC genotype, 24% of them had CA genotype and 44% of patients had AA genotype. Conclusions: Based on the results, using of platinum-based chemotherapy would be expected to be specifically beneficial in only 32% of patients.

The objective of this research was to determine the prevalence, risk factors and consequent effect of dystocia on lactation performance in Holstein dairy cows in Iran. The data set consisted of 55,577 calving records on 30,879 Holstein cows in 30 dairy herds for the period March 2000 to April 2009. Factors affecting dystocia were analyzed using multivariable logistic regression models through the maximum likelihood method in the GENMOD procedure. The effect of dystocia on lactation performance and factors affecting calf birth weight were analyzed using mixed linear model in the MIXED procedure. The average incidence of dystocia was 10.8% and the mean (SD) calf birth weight was 42.13 (5.42) kg. Primiparous cows had calves with lower body weight and were more likely to require assistance at parturition (p<0.05). Female calves had lower body weight, and had a lower odds ratio for dystocia than male calves (p<0.05). Twins had lower birth weight, and had a higher odds ratio for dystocia than singletons (p<0.05). Cows which gave birth to a calf with higher weight at birth experienced more calving difficulty (OR (95% CI) = 1.1(1.08-1.11). Total 305-d milk, fat and protein yield was 135 (23), 3.16 (0.80) and 6.52 (1.01) kg less, in cows that experienced dystocia at calving compared with those that did not (p<0.05).

We present a measurement of the ZZ-boson pair-production cross section in 1.96 TeV center-of-mass energy p (p) over bar collisions. We reconstruct final states incorporating four charged leptons or two charged leptons and two neutrinos from the full data set collected by the Collider Detector experiment at the Fermilab Tevatron, corresponding to 9.7 fb(-1) of integrated luminosity. Combining the results obtained from each final state, we measure a cross section of 1.04(-0.25)(+0.32) pb, in good agreement with the standard model prediction at next-to-leading order in the strong-interaction coupling.

<P>Drell-Yan lepton pairs are produced in the process p (p) over bar -> mu(+)mu(-) + X through an intermediate gamma*/Zboson. The forward-backward asymmetry in the polar-angle distribution of the mu(-) as a function of the invariant mass of the mu(+)mu(-) pair is used to obtain the effective leptonic determination sin(2)theta(lept)(eff) of the electroweakmixing parameter sin(2)theta w, from which the value of sin(2)theta w is derived assuming the standard model. The measurement sample, recorded by the Collider Detector at Fermilab (CDF), corresponds to 9.2 fb(-1) of integrated luminosity from p (p) over bar collisions at a center-of-momentum energy of 1.96 TeV, and is the full CDF Run II data set. The value of sin(2)theta(lept)(eff) is found to be 0.2315 +/- 0.0010, where statistical and systematic uncertainties are combined in quadrature. When interpreted within the context of the standard model using the on-shell renormalization scheme, where sin(2)theta w = 1 - M-W(2)/M-Z(2), the measurement yields sin(2)theta w = 0.2233 +/- 0.0009, or equivalently a W-boson mass of 80.365 +/- 0.047 GeV/c(2). The value of the W-boson mass is in agreement with previous determinations in electron- positron collisions and at the Tevatron collider.</P>
