This paper studies the joint impact of smoothing and fat tails on the risk-return properties of hedge fund strategies. First, we adjust risk and performance measures for illiquidity and the non-Gaussian distribution of hedge funds returns. We use two risk metrics: the Modified Value-at-Risk and a preference-based measure retrieved from the linear-exponential utility function. Second, we revisit the hedge fund diversification effect with these adjustments for illiquidity. Our results report similar fund performance rankings and optimal hedge fund strategy allocations for both adjusted metrics. We also show that the benefits of hedge funds in portfolio diversification are still persistent but tend to weaken after the adjustment for illiquidity. [less ▲]

The impact of in vivo T-cell depletion on transplantation outcomes in patients transplanted with reduced-intensity conditioning (RIC) remains controversial. This study assessed the outcome of 1250 adult patients with de novo AML in first CR (CR1) given PBSC from HLA-identical siblings after chemotherapy-based RIC. A total of 554 patients did not receive any form of in vivo T-cell depletion (control group), whereas antithymocyte globulin (ATG) and alemtuzumab were given in 444 and 252 patients, respectively. The incidences of grade II-IV acute GVHD were 21.4, 17.6 and 10.2% in control, ATG and alemtuzumab patients, respectively (Po0.001). In multivariate analysis, the use of ATG and the use of alemtuzumab were each associated with a lower risk of chronic GVHD (Po0.001 each), but a similar risk of relapse, and of nonrelapse mortality, and similar leukemia-free survival and OS. Further, among patients given BU-based RIC, the use of o6 mg/kg ATG did not increase the risk of relapse (hazard ratio, HR¼1.1), whereas there was a suggestion for higher relapse risk in patients given X6 mg/kg ATG (HR¼1.4, P¼0.08). In summary, these data suggest that a certain amount of in vivo T-cell depletion can be safely used in the conditioning of AML patients in CR1 given PBSC after chemotherapy-based RIC. [less ▲]

In shotgun proteomics, the gold standard technique is reversed-phase liquid chromatography coupledto mass spectrometry. Many researches have been carried out to study the effects on identification per-formances of chromatographic parameters such as the stationary phase and column dimensions, mobilephase composition and flow rate, as well as the gradient slope and length. However, little attention isusually paid to the injection solvent composition.In this study, we investigated the effect of the injection solvent on protein identification parameters(number of distinct peptides, amino acid coverage and MS/MS search score) as well as sensitivity. Trypticpeptides from six different proteins, covering a wide range of physicochemical properties, were employedas training set. Design of experiments was employed as a tool to highlight the factors related to thecomposition of the injection solvent that significantly influenced the obtained results. Optimal resultsfor the training set were applied to analysis of more complex samples. The experiments pointed outoptimising the composition of the injection solvent had a strong beneficial effect on all the consideredresponses. On the basis of these results, an approach to determine optimal conditions was proposed tomaximise the protein identification performances and detection sensitivity. [less ▲]

The risks to fauna associated with the use of pesticides are generally known for individual pesticides. There exists, however, a lack of pub Iished material providing comparative coverage of all pesticides, although some partial compilations have been published. ln an attempt to redress this situation, we propose here a Toxicity Index covering fish, birds and bees for 169 currently available insecticides.

Intensive enteral nutrition by feeding tube does not improve 6-month survival in patients with severe alcoholic hepatitis. However, adequate nutritional support is associated with a better short-term prognosis. Adequate nutritional intake should be targeted in alcoholic hepatitis patients treated with corticosteroids.

The effects of intercropping of wheat cultivars and oilseed rape on the densities of wheat aphid, Sitobion avenae, and their arthropod natural enemies were evaluated. Three winter wheat cultivars with different resistant levels to S. avenae were used: `KOK¿ (high resistance), `Xiaobaidongmai¿ (low resistance) and`Hongmanghong¿ (susceptible). The results showed that the densities of S. avenae were significantly higher on the monoculture pattern than on either the 8-2 intercropping pattern (eight rows of wheat with two rows of oilseed rape) or the 8-4 intercropping pattern (eight rows of wheat with four rows of oilseed rape). The mean number of predators and the mummy rates of S. avenae were significantly higher in two intercropping patterns than those in the monoculture pattern. The densities of S. avenae, ladybeetles, and mummy rate of S. avenae were significantly different among different wheat cultivars. The highest densities of S. avenae and ladybeetles were found on wheat cultivar Hongmanghong. The lowest densities of S. avenae associated with high mummy rate of S. avenae were found on wheat cultivar Xiaobaidongmai. The results showed that wheat-oilseed rape intercropping conserved more predators and parasitoids than in wheat monoculture fields, and partial resistance of wheat cultivar Xiaobaidongmai had complementary or even synergistic effects on parasitoid of S. avenae.

We evaluated the impact of two iron and steel plants and two municipal solid waste incinerators (MSWI) in Wallonia (Belgium) on the exposure of residents to dioxins, polychlorinated biphenyls (PCBs), and heavy metals. In total, 142 volunteers living around these facilities were recruited and compared with 63 referents from a rural area with no industrial source of pollution. Information about smoking habits, dietary habits, anthropometric characteristics, residential history, and health status was obtained from a self-administered questionnaire. The volunteers provided blood under fasting conditions in order to evaluate the body burden of dioxins (17 polychlorinated dibenzo-p-dioxins/dibenzofurans [PCDD/Fs] congeners) and PCBs. Samples of blood and urine were also taken for the determination of cadmium, mercury, and lead. After adjustment for covariates, concentrations of cadmium, mercury, and lead in urine or blood were not increased in subjects living in the vicinity of MSWIs or sinter plants by comparison with referents. Residents around the sinter plants and the MSWI located in the industrial area had concentrations of dioxins and PCBs in serum similar to that of referents. By contrast, subjects living in the vicinity of the MSWI in the rural area showed significantly higher serum levels of dioxins (geometric mean, 38 vs. 24 pg TEQ/g fat) and coplanar PCBs (geometric mean, 10.8 vs. 7.0 pg TEQ/g fat). Although age-adjusted dioxin levels in referents did not vary with local animal fat consumption, concentrations of dioxins in subjects living around the incinerators correlated positively with their intake of local animal fat, with almost a doubling in subjects with the highest fat intake. These results indicate that dioxins and coplanar PCBs emitted by MSWIs can indeed accumulate in the body of residents who regularly consume animal products of local origin. [less ▲]
