TL;DR: The use of intravenous colistin for the treatment of infections due to multidrug-resistant gram-negative bacteria appears to be safe and effective, and the absence of a control group constitutes the major limitations of this study.
Abstract: Colistin, an antibiotic almost abandoned for intravenous administration for many years due to its reported toxicity, has been recently reintroduced in clinical practice due to the emergence of multidrug-resistant gram-negative bacteria and the lack of development of new antibiotics to combat them. To assess the safety and effectiveness of intravenous colistin, in combination with other antimicrobial agents, in the treatment of serious infections in patients without cystic fibrosis, a retrospective cohort study in a 450-bed tertiary-care hospital in Athens, Greece, was performed. Patients who were hospitalized from 1 October 2000 to 31 January 2004 and received intravenous colistin for more than 72 h were further analyzed. The primary outcome measure was the in-hospital mortality; secondary end points were the clinical outcome of the infections and the occurrence of colistin toxicity. Fifty patients received intravenous colistin with a median (mean) daily dose of 3 (4.5) million IU for 16.5 (21.3) days for the management of 54 episodes of infections due to multidrug-resistant gram-negative bacteria. The predominant infections were pneumonia (33.3%), bacteremia (27.8%), urinary tract infection (11.1%), and intra-abdominal infection (11.1%). The responsible pathogens were Acinetobacter baumannii (51.9%), Pseudomonas aeruginosa (42.6%), and Klebsiella pneumoniae (3.7%) strains (no pathogen was isolated from one case). In-hospital mortality was 24% (12/50 patients). Clinical response (cure or improvement) of the infection was observed in 66.7% of episodes (36/54). In the studied group, serum creatinine levels were decreased, at the end of colistin treatment, by an average of 0.2 ± 1.3 mg/dl compared to baseline levels. Deterioration of renal function during colistin therapy was observed in 4/50 patients (8%). Coadministration of other antimicrobial agents with spectrum against gram-negative microorganisms and the absence of a control group constitute the major limitations of this study. The use of intravenous colistin for the treatment of infections due to multidrug-resistant gram-negative bacteria appears to be safe and effective.

TL;DR: The short-term changes observed in the present study are markedly encouraging and indicate great potential for progressive improvement and Continuation and expansion of such a program may prove to be beneficial in initiating long- term changes.

TL;DR: Energy techniques are combined with an appropriate pointwise representation of the error based on an elliptic reconstruction operator which restores the optimal order (and regularity for piecewise polynomials of degree higher than one).
Abstract: It is known that the energy technique for a posteriori error analysis of finite element discretizations of parabolic problems yields suboptimal rates in the norm $L^\infty (0,T; L^2 (\Omega)).$ In this paper, we combine energy techniques with an appropriate pointwise representation of the error based on an elliptic reconstruction operator which restores the optimal order (and regularity for piecewise polynomials of degree higher than one). This technique may be regarded as the "dual a posteriori" counterpart of Wheeler's elliptic projection method in the a priori error analysis.

TL;DR: In this review, the advances in genes and proteins of polyamine catabolism in plants is presented and compared to other models.
Abstract: Polyamines have long been implicated in plant adaptation to abiotic and biotic stress. As a general rule of thumb the higher the polyamine titers the better. However, their molecular roles in plant stress responses still remain obscure. It has been postulated that they could act through their catabolism, which generates molecules which may act as secondary messengers signalling networks of numerous developmental and stress adaptation processes. Recently it was shown that plant and mammalian polyamine catabolism share critical features, giving new insight in plant polyamine catabolism. In this review, the advances in genes and proteins of polyamine catabolism in plants is presented and compared to other models.
