Background: Intramuscular fat(IMF) content is a relevant trait for high-quality meat products such as dry-cured ham,but increasing IMF has the undesirable correlated effect of decreasing lean ***,there is a need to find selection criteria for IMF independent from lean *** pigs,the proportion of linoleic(C18:2) and arachidonic(C20:4) acids decline with fat deposition and therefore they can be considered as indicators of *** aim of this research was to estimate the genetic variation for C18:2 and C20:4 in IMF and their genetic correlations with IMF and lean growth traits,with the objective to assess their potential as specific biomarkers of *** analysis was conducted using a full-pedigreed Duroc resource line with 91,448 records of body weight and backfat thickness(BT) at 180 days of age and 1371 records of fatty acid composition in the muscle gluteus ***: The heritability estimates for C18:2 and C20:4 in IMF,whether expressed in absolute(mg/g of muscle) or in relative(mg/g of fatty acid) terms,as well as for their ratio(C20:4/C18:2),were high(> 0.40),revealing that the C18:2 to C20:4 pathway is subjected to substantial genetic *** effects were not negligible,with values ranging from8% to 15% of the phenotypic *** genetic correlations of C18:2 and C20:4 with IMF and BT were negative(-0.75 to-0.66,for IMF,and-0.64 to-0.36,for BT),if expressed in relative values,but almost null(-0.04 to 0.07),if expressed in absolute values,except for C18:2 with IMF,which was highly positive(0.88).The ratio of C20:4 to C18:2 also displayed a stronger genetic correlation with IMF(-0.59) than with BT(-0.10).Conclusions: The amount of C18:2 in muscle can be used as an IMF-specific *** for the absolute amount of C18:2 is expected to deliver a similar response outcome as selection for IMF at restrained *** genetic analysis of the C18:2 metabolic pathway may provide new insights into differential fat deposition

北京论坛（2011）文明的和谐与共同繁荣--传统与现代、变革与转型

作者： tor Eriksson Aarhus School of Business Aarhus University

This paper provides estimates of brother income correlations for rural China. Brother correlations are a parsimonious measure of the importance of family and community background as determinants of individuals’ economic status. We find internationally high levels of income similarity for brothers and siblings: 0.57 and 0.58,respectively. We show that compared with the 1990s, income correlations have decreased in more recent years, but remain high. Furthermore,we document virtually no differences between the coastal and interior provinces and by father’s education. The high brother correlations imply that the high level of income inequality in China is likely to persist.

1、引言在数百万年的地质历史上，原油、盐水和岩石（原油－盐水－岩石，简称CBR）之间已经建立了化学平衡，这个化学平衡系统包含了油藏的所有组成部分。在建立了化学平衡后，岩石孔隙中石油和地层水就会维持在一定的含油饱和度和含水饱和度水平。由于油藏中石油和水的组分存在一定的梯度，而且岩石性质具有非均质性，因而石油和水的相对分布可能会有些许的变化。

Sensing, Signal Processing, and Communication for WBANs

A wireless body area network （WBAN） enables real-time monitoring of physiological signals and helps with the early detection of life-threatening diseases. WBAN nodes can be located on, inside, or in close proximity to the body in order to detect vital signals. Measurements from sensors are processed and transmitted over wireless channels. Issues in sensing, signal processing, and com-munication have to be addressed before WBAN can be implemented. In this paper, we survey recent advances in research on sig-nal processing for the sensor measurements, and we describe aspects of communication based on IEEE 802.15.6. We also discuss state-of-the-art WBAN channel modeling in all the frequencies specified by IEEE 802.15.6 as well as the need for new channel models for new different frequencies.

Re, Os concentrations and Os isotopic compositions of the Dongling ⅢCD iron meteorite were determined by N-TIMS technique. The result was compared with that of the other irons and chondrites. The Re and Os concentrations of the Dongling iron meteorite were plotted on the trends of the group ⅢA and ⅣA irons. The Pt-Os relation of the Dongling iron meteorite is similar to that of the group ⅡA irons. That suggests a higher fractionation for the Dongling iron meteorite.

Autoimmune hepatitis in a patient infected by HIV-1 and under highly active antiretroviral treatment:Case report and literature review

Liver disease has recently been described as an im-portant cause of morbidity and mortality in patientsinfected with human immunodeficiency virus （HIV）.Liver test changes are useful surrogates of the burdenof liver disease. Previous studies have shown that trans-aminase elevations are frequent among these *** cause of those changes is harder to establish inHIV-patients. We present a 61-year-old caucasian male,diagnosed with HIV type 1 infection since 1998, underhighly active antiretroviral treatment （HAART）, withvirological suppression and immunological *** presented in a follow-up laboratory workup highvalues of transaminases, arthralgia at the hip joints and hepatomegaly. Liver function tests were normal. Theantibodies to hepatitis viruses were negative. However,autoimmune study and liver biopsy were compatible with autoimmune hepatitis （AIH）. The AIH is a rare di-agnosis in HIV-infected patients perhaps because the elevation of transaminases and changes in liver function tests are often associated to HAART or to other possible liver diseases, namely viral hepatitis and non-alcoholic steatohepatitis. The diagnosis may be underestimated. There are no specifc recommendations available for the treatment of HIV-associated AIH although the immuno-supression with slower tapering seems the most reason-able approach.
