The product of the ∧0/b （-B/0） differential production cross-section and the branching fraction of the decay ∧0/b→ J/ψ pK-（-B/0→ J/ψ-K＊（892）0）is measured as a function of the beauty hadron transverse momentum, PT, and rapidity, y. The kinematic region of the measurements is pT〈20 GeV/c and 2.0 〈g〈*** measurements use a data sample corresponding to an integrated luminosity of 3fb-1 collected by the LHCb detector in pp collisions at centre-of-mass energies √s=7 TeV in 2011 and √s=8 TeV in 2012. Based on previous LHCb results of the fragmentation fraction ratio,f∧0/b/fd,the branching fraction of the decay ∧0/b→ J/ψ pK-is measured to be B（∧0/b→ J/ψ pK-）=（3.17±0.04±0.07±0.34＋0.45/-0.28）×10-4,where the first uncertainty is statistical, the second is systematic, the third is due to the uncertainty on the branching fraction of the decay -B/0 →J/ψ-K＊（892）0,and the fourth is due to the knowledge of f∧0/b/*** sum of the asymmetries in the production and decay between ∧0/b and ∧0/bis also measured as a function of PT and *** previously published branching fraction of ∧0/b→ J/ψ pπ-,relative to that of ∧0/b→ J/ψ pK-,is updated. The branching fractions of ∧0/b→P＋c（→ J/ψp）K-are determined.

AIM: To investigate whether the presence of human leukocyte antigen(Hla) marker could add new information to discriminated atypical diabetic type 2 ***: We analyzed 199 patients initially diagnosed as type 2 diabetes who are treated in special care diabetes clinics(3rd level). This population was classified in "atypical"(sample A) and "classic"(sample B) according to Hla typing. We consider "classic patient" when has absence of type 1 diabetes associated Hla alleles and no difficulties in their diagnosis and treatments. By the other hand, we considered "atypical patient" when show type 1 diabetes associated Hla alleles and difficulties in their diagnosis and treatments. The standard protocol Asociacion latinoamericana de Diabetes 2006 was used for patients follow up. To analyze differences between both populations in paraclinical parameters we used unpaired t tests and contingence tables. Bivariate and multivariate analyses were carried out using the SPSS software program. In all studies we assume differences statistically significant, with a P-value la in the "atypical" populations show that 92.47% patients presented at list one type 1 diabetes associated Hla alleles(DQB1*0201-0302 and DR 3-4) and 7.53% had two of its. The results showed for categorical variables(family history, presence or absence of hypertension and/or dyslipidemia, reason for initial consultation) the only difference found was at dyslipidemia(OR = 0.45, 0.243 lation to continuous variables we found significant differences between atypical vs classic only in cholesterol(5.07 ± 1.1 vs 5.56 ± 1.5, P density lipoproteins(1.23 ± 0.3 vs 1.33 ± 0.3, P density lipoproteins(2.86 ± 0.9 vs 3.38 ± 1.7, P la genotyping as a tool to discriminate atypical p

分别对经0.1、1.0μL.L-1浓度的1-甲基环丙烯(1-MCP)处理和未经1-MCP处理的离体菠菜叶片的衰老特性进行研究。结果表明,与对照相比,经1-MCP处理的菠菜叶片在避光、23℃条件下贮藏6 d后,叶绿素含量和光系统Ⅱ最高光量子产量较高,溶质渗漏量较低,说明1-MCP处理可延缓菠菜叶片的衰老。贮藏3 d后,经1-MCP处理的菠菜叶片乙烯生成量增加,随后又下降至对照水平。经1-MCP处理的菠菜叶片中具有较高的抗坏血酸和谷胱甘肽含量及对于这两种物质较低的氧化还原比率。1-MCP处理还可以减少菠菜叶片中的铵盐积累及蛋白质的降解。综合上述结果可以得出,通过1-MCP抑制菠菜叶片对乙烯作用的敏感性可有效延长菠菜的采后保鲜期。

During the hydrogenation process of vegetable, oils originates isomer with trans fatty acids (TFA). Various investigations have been made to know the effect of TFA on health and it has been reported in the literature that if they are consumed in large proportions increases low density lipoprotein causing an imbalance in cholesterol, which causes cardiovascular problems. As a result, some countries have legislated and regulated the TFA content in foods. The purpose of this work is to study the FA of the butters produced from hydrogenated vegetable oil (MV) and pure cow"s milk (MPV) with and without oxidation by Fourier Transform Infrared Spectroscopy (FTIR) spectroscopy. The butters were acquired at a local supermarket and oxidized at 200 oC by 30 min. Infrared Radiation (IR) measurements were carried out in the Attenuated Total Reflectance mode and in the region of 400-4000 cm-1. IR spectra of the two butters with and without oxidation present absorption bands around 968 and 3006 cm-1, which are characteristic of the functional groups trans and cis, respectively. The MV presented a greater intensity; in addition, it was more stable to heat treatment. With FTIR is possible to define precisely the peak associated with the functional group cis.
