IFD incidence was found to be significant while receiving itraconazole prophylaxis compared with no prophylaxis (0.027 vs. 0.053 IFD/patient-years; P < 0.01). Median age at IFD diagnosis was 6.5 years (3.3-11.3). The most common fungal genus was Aspergillus sp. accounting for 40% of all IFDs. Of the IFDs, 42.5% were proven, 30.0% probable, and 27.5% possible. Of all IFD episodes, 52.5% were treated

by antifungal monotherapy, mostly by amphotericin B. Survival was reduced in IFD patients compared selleck with those without it (log-rank = 0.04).

Conclusions: IFDs are a frequent and life-threatening complication in CGD patients. Itraconazole significantly reduces its incidence and should be recommended in absence of better alternatives.”
“In shoot cultures of Thymus daenensis,

hyperhydricity syndrome promoted by benzyladenine (BA) is characterised by the development of chlorophyll-deficient shoots with a high water content and reduced growth that is less differentiated. By removing the BA from the culture medium, the hyperhydricity Autophagy inhibitor cell line was reversed, and the reversion toward a normal growth in vitro was more efficient in shoots treated with 5 mu M of salicylic acid (SA), showing a significant increase in chlorophyll b after 4 weeks of culture. In the present study, the effect of salicylic acid on the reversion of shoot hyperhydricity was investigated at the level of the free, soluble and insoluble conjugated polyamine content. In T daenensis micropropagated shoots, the level of polyamines was high, with a predominance of putrescine. BA, which triggered hyperhydricity, caused a reduction of the polyamine (PA) content by one-half due to a decrease in the putrescine content and insoluble conjugated PAs that were not detected in the hyperhydric shoots. In the reverted shoots, changes of the free polyamines, spermidine and, more notably, spermine, were shown. The spermine content doubled after 4 weeks of culture, and its amount was the same as that found STI571 in vitro in normal shoots, suggesting that free spermine could be particularly involved in the reversion of hyperhydricity. In the SA-reverted tissues, the PA pattern was marked with a transient increase of free

putrescine, spermidine and spermine and an enhancement of soluble conjugated spermine. This transitory SA-dependent amplification of PAs was concomitant with a remarkable transient increase of H2O2, suggesting that SA may be implicated in PA signalling pathways for tissue differentiation during the reversion of hyperhydricity in T daenensis.

“The temperature dependence of the electrical resistivity and the thermoelectric power in (Ni1-xCux)Mn2O4 (x = 0 to 0.5) and Ni(Mn2-yCuy)O-4 (y = 0 to 0.2) are investigated. The electrical resistivity of samples with x < 0.1 appears to be hardly changed with increasing Cu content. In all of the samples, the electron transfer is thermally activated and shows semiconducting behavior.
