CKM physics at CDF
A precise knowledge of the CKM matrix elements is one of the primary goals of the CDF experiment. The Tevatron collider at Fermilab, operating at s = 1.96 , collected 1 f b −1 of data corresponding to a huge b b ¯ sample. In this paper the recent measurements performed in the CKM sector will be presented
Recent results on the Unitarity Triangle from Tevatron
I report on the recent results of Tevatron experiments on the Unitarity Triangle. In particular the measurements of the direct CP asymmetry (ACP ) and of the double ratio of CP-even (D → K−K+ or π−π+) to flavor (D → K−π+) eigenstate branching fraction (RCP) in the B → DK decays, that can be used to improve the determination of the CKM angle γ, and the search for new physics in the CP-violating Bs phase βs using the B0s → J/ψφ decay

Results on rare decays and other cp violation at the Tevatron
We present the current status of the rare decay searches of B{sup 0}{sub (s)} {yields} {mu}{sup +}{mu}{sup -}, B {yields} {mu}{sup +}{mu}{sup -}h, D{sup +} {yields} {pi}{sup +}{mu}{sup +}{mu}{sup -} and B{sup 0}{sub (s)} {yields} h{sup +}h'{sup -} at the Tevatron Collider. We also report about the latest results on CP Violation for B{sup 0} and B{sup 0}{sub s} decay modes into pairs of charmless charged hadrons (pions and kaons)

Effect of colostrum and milk on small intestine expression of AQP4 and AQP5 in newborn buffalo calves.
Functional studies indicate differences in newborn gastrointestinal morphology and physiology after a meal. Both water and solutes transfer across the intestinal epithelial membrane appear to occur via aquaporins (AQPs). Given that the physiological roles of AQP4 and AQP5 in the developing intestine have not been fully established, the objective of this investigation was to determine their distribution, expression and respective mRNA in the small intestine of colostrums-suckling buffalo calves by using immunohistochemistry, Western blot, and reverse transcriptase-PCR analysis. Results showed different tissue distribution between AQP4 and AQP5 with the presence of the former along the enteric neurons and the latter in the endocrine cells. Moreover, their expression levels were high in the ileum of colostrum-suckling buffalo calves. The data present a link between feeding, intestinal development and water homeostasis, suggesting the involvement of these channel proteins in intestinal permeability and fluid secretion/absorption during this stage of development after birth
Chronic bronchitis without airflow obstruction, asthma and rhinitis are differently associated with cardiovascular risk factors and diseases
Cardiovascular and respiratory diseases can frequently coexist. Understanding their link may improve disease management. We aimed at assessing the associations of chronic bronchitis (CB), asthma and rhinitis with cardiovascular diseases and risk factors in the general population
Antioxidative Effects of Curcumin on the Hepatotoxicity Induced by Ochratoxin A in Rats
Ochratoxin A (OTA) is a powerful mycotoxin found in various foods and feedstuff, responsible for subchronic and chronic toxicity, such as nephrotoxicity, hepatotoxicity, teratogenicity, and immunotoxicity to both humans and several animal species. The severity of the liver damage caused depends on both dose and duration of exposure. Several studies have suggested that oxidative stress might contribute to increasing the hepatotoxicity of OTA, and several antioxidants, including curcumin (CURC), have been tested to counteract the toxic hepatic action of OTA in various classes of animals. Therefore, the present study was designed to evaluate the protective effect of CURC, a bioactive compound with different therapeutic properties on hepatic injuries caused by OTA in rat animal models. CURC effects were examined in Sprague Dawley rats treated with CURC (100 mg/kg), alone or in combination with OTA (0.5 mg/kg), by gavage daily for 14 days. At the end of the experiment, rats treated with OTA showed alterations in biochemical parameters and oxidative stress in the liver. CURC dosing significantly attenuated oxidative stress and lipid peroxidation versus the OTA group. Furthermore, liver histological tests showed that CURC reduced the multifocal lymphoplasmacellular hepatitis, the periportal fibrosis, and the necrosis observed in the OTA group. This study provides evidence that CURC can preserve OTA-induced oxidative damage in the liver of rat
Observation of the Baryonic Flavor-Changing Neutral Current Decay Lambda_b -> Lambda mu+ mu-
We report the first observation of the baryonic flavor-changing neutral
current decay Lambda_b -> Lambda mu+ mu- with 24 signal events and a
statistical significance of 5.8 Gaussian standard deviations. This measurement
uses ppbar collisions data sample corresponding to 6.8fb-1 at sqrt{s}=1.96TeV
collected by the CDF II detector at the Tevatron collider. The total and
differential branching ratios for Lambda_b -> Lambda mu+ mu- are measured. We
find B(Lambda_b -> Lambda mu+ mu-) = [1.73+-0.42(stat)+-0.55(syst)] x 10^{-6}.
We also report the first measurement of the differential branching ratio of B_s
-> phi mu+ mu- using 49 signal events. In addition, we report branching ratios
for B+ -> K+ mu+ mu-, B0 -> K0 mu+ mu-, and B -> K*(892) mu+ mu- decays.Comment: 8 pages, 2 figures, 4 tables. Submitted to Phys. Rev. Let
