Remarkably, transitivity was impaired proportionally with the length of the pre-mRNA, and not of the mRNA. The latter result suggests that the RNA-dependent RNA polymerase-based spreading of silencing progresses along the non-spliced rather than the fully processed mature mRNA.”
“Arachnoiditis involving optic nerve and the https://www.selleckchem.com/products/DMXAA(ASA404).html optic chiasm can occur as a complication of tuberculous meningitis

(TBM). This study evaluates the clinical features, cerebrospinal fluid (CSF) and laboratory parameters and imaging findings of optochiasmatic arachnoiditis (OCA) and also tried to identify any factors which can predict this complication in patients with TBM. Patients admitted with TBM in the neurology wards of a tertiary care teaching hospital over a period of 6 years formed the material for this study. Students “t” test and

univariate analysis were done to identify any predictors for this complication and the variables found to be significant were further analyzed by multivariate logistic regression analysis. One hundred sixty-three patients with TBM, admitted over a 6-year period, were studied. Twenty-three (14) patients developed OCA. Eighteen out of 23 (78) developed this complication while on antituberculous treatment (ATT) and 5/23 (22) were newly diagnosed cases of TBM. Of those already on treatment, 12/23 (52) were receiving only ATT, the remaining 6/23 (26) had received steroids along with ATT in varying doses and duration. The average period from diagnosis of TBM to visual symptoms was 6.4 months. On the multivariate logistic regression analysis, female sex (P < 0.037), age ARS-1620 price less GSI-IX cell line than 27 (P < 0.008) years and protein content in the CSF > 260 mg (P < 0.021) were the factors predisposing toward this complication. At 6 months follow-up, on treatment with steroids and ATT,

17 had improvement and no further deterioration was noted in visual acuity in 52. OCA can develop even while on treatment with ATT. Young women with a high CSF protein content seem to be more prone for this complication.”
“The aim of this study is to determine the short-term effects of fire on nitrogen and phosphorus soil concentration in heathland sites dominated by Calluna Vulgaris in the Cantabrian Mountain range (NW Spain). Three C. vulgaris heathlands sites (San Isidro, Riopinos I and Riopinos II) were selected. In June 2005, one plot (20 m x 20 m) per site was subjected to an experimental fire and the other was used as a control. Immediately after the fire, ten ash samples and ten soil samples (at a depth of 5 cm) were collected and thoroughly mixed. Soil moisture, temperature, total N, NH4+, NO3-, total P, available P and pH were determined in each sample. The quantity of ashes deposited was 300 g/m(2), with a pH of 9, low N content but higher P concentrations. Significant differences in temperature and soil moisture were detected between the fire-treated and control plots.
