This article is a clinical guide which discusses the “state-of-the-art” usage of the classic monoamine oxidase inhibitor (MAOI) antidepressants (phenelzine, tranylcypromine, and isocarboxazid) in modern psychiatric practice. The guide is for all clinicians, including those who may not be experienced MAOI prescribers. It discusses indications, drug-drug interactions, side-effect management, and the safety of various augmentation strategies. There is a clear and broad consensus (more than 70 international expert endorsers), based on 6 decades of experience, for the recommendations herein exposited. They are based on empirical evidence and expert opinion—this guide is presented as a new specialist-consensus standard. The guide provides practical clinical advice, and is the basis for the rational use of these drugs, particularly because it improves and updates knowledge, and corrects the various misconceptions that have hitherto been prominent in the literature, partly due to insufficient knowledge of pharmacology. The guide suggests that MAOIs should always be considered in cases of treatment-resistant depression (including those melancholic in nature), and prior to electroconvulsive therapy—while taking into account of patient preference. In selected cases, they may be considered earlier in the treatment algorithm than has previously been customary, and should not be regarded as drugs of last resort; they may prove decisively effective when many other treatments have failed. The guide clarifies key points on the concomitant use of incorrectly proscribed drugs such as methylphenidate and some tricyclic antidepressants. It also illustrates the straightforward “bridging” methods that may be used to transition simply and safely from other antidepressants to MAOIs.

Summary
Accidental hypothermia can be of multiple aetiologies and is often related to an accident in a cold environment and contrasts with urban hypothermia. People living in the cold such as workers, fishermen and military personnel are at risk. More recently there is an increase in unprepared lay people practicing leisure activities such as winter sports, thus exposing themselves to hypothermia in case of an accident. Most of the cases concern mild hypothermia which does not need hospitalization or medical assistance. In contrast, deep hypothermia, with or without cardiac arrest, is rare and carries a high mortality in healthy adults and children [1, 2, 3].
Induced hypothermia which has been used for cardiac surgery as well as therapeutic hypothermia used for brain ischaemia, are medically indicated and highly monitored and therefore cannot be compared to accidental hypothermia. Patients with induced hypothermia may reach the same degree (< 28°C) but are in controlled narcosis and are normally cooled down and rewarmed by Cardiopulmonary Bypass (CPB) [4]. Therapeutic hypothermia cools the patient to mild hypothermia (32–34°C) to enhance a better and faster functional brain recovery [5].
The concept of applying the technique of CPB rewarming, as used in induced deep hypothermic cardiac arrest, to victims of accidental hypothermia with temperatures below 28°C and cardio-respiratory arrest was initiated successfully by Prof. Ueli Althaus at the University Hospital Insel in Bern, Switzerland over 30 years ago [6]. Since that time our team and other Swiss universities started to use this method and we published a multi-centre study showing a long-term sequelae-free survival rate of 47% after rewarming of 32 deep accidental hypothermic patients in cardiac arrest using cardiopulmonary bypass (CPB) [7]. Due to the fact that many patients died from post-rewarming complications, we and others have shown the beneficial effect of using extra-corporeal life support (ECLS) such as prolonged ECMO use after rewarming for cardiovascular and pulmonary dysfunctions [8, 9].

Summary
Radiotracer imaging methods such as single-photon emission computed tomography (SPECT) and positron emission tomography (PET) are well suited to provide information about the functional, metabolic, and molecular status of tissues and organs. Brain SPECT has a well-established role for a number of clinical indications. Cerebral perfusion studies are used in the evaluation of dementias, epilepsy, cerebrovascular disease, trauma, brain death, and to assist with neuropsychiatric evaluation. Brain function is evaluated at baseline, before and after pharmacotherapy or psychotherapy, and following a number of activation tasks to examine a large number of psychiatric conditions. The integration of SPECT and CT in a single imaging device facilitates anatomical localization of the radiopharmaceutical to differentiate physiological uptake from that associated with disease. SPECT and SPECT/CT is continuing to evolve with the introduction of new technologies that have the potential to improve performance beyond that possible with Anger's pioneering approach.

The science of extra-solar planets is one of the most rapidly changing areas of astrophysics and since 1995 the number of planets known has increased by almost two orders of magnitude. A combination of ground-based surveys and dedicated space missions has resulted in 560-plus planets being detected, and over 1200 that await confirmation. NASA's Kepler mission has opened up the possibility of discovering Earth-like planets in the habitable zone around some of the 100,000 stars it is surveying during its 3 to 4-year lifetime. The new ESA's Gaia mission is expected to discover thousands of new planets around stars within 200 parsecs of the Sun. The key challenge now is moving on from discovery, important though that remains, to characterisation: what are these planets actually like, and why are they as they are?
In the past ten years, we have learned how to obtain the first spectra of exoplanets using transit transmission and emission spectroscopy. With the high stability of Spitzer, Hubble, and large ground-based telescopes the spectra of bright close-in massive planets can be obtained and species like water vapour, methane, carbon monoxide and dioxide have been detected. With transit science came the first tangible remote sensing of these planetary bodies and so one can start to extrapolate from what has been learnt from Solar System probes to what one might plan to learn about their faraway siblings. As we learn more about the atmospheres, surfaces and near-surfaces of these remote bodies, we will begin to build up a clearer picture of their construction, history and suitability for life.
The Exoplanet Characterisation Observatory, EChO, will be the first dedicated mission to investigate the physics and chemistry of Exoplanetary Atmospheres. By characterising spectroscopically more bodies in different environments we will take detailed planetology out of the Solar System and into the Galaxy as a whole.
EChO has now been selected by the European Space Agency to be assessed as one of four M3 mission candidates.

We address the sensitivity of large-eddy simulations (LES) to parametric uncertainty in the subgrid-scale model. More specifically, we investigate the sensitivity of the LES statistical moments of decaying homogeneous isotropic turbulence to the uncertainty in the Smagorinsky model free parameter Cs (i.e. the Smagorinsky constant). Our sensitivity methodology relies on the non-intrusive approach of the generalized Polynomial Chaos (gPC) method; the gPC is a spectral non-statistical numerical method well-suited to representing random processes not restricted to Gaussian fields. The analysis is carried out at Reλ, =, 100 and for different grid resolutions and Cs distributions. Numerical predictions are also compared to direct numerical simulation evidence. We have shown that the different turbulent scales of the LES solution respond differently to the variability in Cs. In particular, the study of the relative turbulent kinetic energy distributions for different Cs distributions indicates that small scales are mainly affected by changes in the subgrid-model parametric uncertainty.

A theoretical analysis is presented on the behaviour of the model coefficients for the well-known Smagorinsky model and two variational multi-scale (VMS) variants of the Smagorinsky model. The dependency on two important parameters is addressed, i.e. the ratio of the LES-filter width $\varDelta$ and the Kolmogorov scale $\eta$ on the one hand, and the ratio of the integral length scale $L$ and the LES-filter width $\varDelta$ on the other hand. First of all, it is demonstrated that the model coefficients vary strongly with $\varDelta/\eta$. By evaluating the model coefficients as functions of the subgrid activity $s$ (which expresses the relative contribution of the subgrid-scale model in the total dissipation, and corresponds to a nonlinear transformation of $\varDelta/\eta$), we show that a classical Lilly–Smagorinsky model overestimates the dissipation, even in cases where the dissipation of the subgrid-scale model is dominant. Therefore, generic and easy-to-use modifications to the different models are proposed, which provide close approximations to the models employing ‘exact’ coefficients. For the standard Smagorinsky model, this modified model corresponds to approximating the eddy viscosity $\nu_t$ as $\nu_t\,{=}\,(\nu_{\mbox{\textit{\scriptsize Lilly}}}^2\,{+}\,\nu^2)^{1/2} -\nu$, with $\nu_{\mbox{\textit{\scriptsize Lilly}}}$ the turbulent viscosity obtained by employing Lilly's classical Smagorinsky constant and $\nu$ the laminar viscosity. Similar easy-to-use relations are presented for the variational multi-scale Smagorinsky models. Next to the $\varDelta/\eta$ dependence of the model coefficients, the $L/\varDelta$ behaviour is also elaborated. Although a strong dependence on $L/\varDelta$ is observed for low values of the ratio, we do not advocate the use of $L/\varDelta$-dependent model coefficients. Rather, the asymptotic $L/\varDelta$ independence and the speed of asymptotic convergence are used as a tool to compare the quality of subgrid-scale models (e.g. $L/\varDelta \,{>}\, 10$ is a minimum order of magnitude for the small–small VMS model), and differences are observed between the standard Smagorinsky model and its two VMS variants. Finally, for the VMS models, the influence of the shape of the high-pass filter, used in the variational multi-scale formulation, is investigated. We observed that smooth high-pass filters result in more robust VMS Smagorinsky models.

The advantages of fluorine co-implantation on reducing the deep P junction profile is investigated and commented as a possible valuable solution for further scaling of the NMOS transistors spacer length. On PMOS transistors, Ge+C+B cocktail junctions lead to improved short channel effects control, S/D resistance and performance over the conventional approaches. Additional laser annealing induces a partial dissolution of the doping clusters in the junction and lower the S/D transistors resistance. A performance improvement is demonstrated both for NMOS and PMOS with cocktail junctions activated by spike RTA and additional laser annealing.

Objective:
To evaluate a new classification for bloodstream infections that differentiates hospital acquired, healthcare associated, and community acquired in patients with blood cultures positive for Staphylococcus aureus.
Design:Prospective, observational study.
Setting:Three tertiary-care, university-affiliated hospitals in Dublin, Ireland, and Strasbourg, France.
Patients:Two hundred thirty consecutive patients older than 18 years with blood cultures positive for S. aureus.
Methods:S. aureus bacteremia (SAB) was defined as hospital acquired if the first positive blood culture was performed more than 48 hours after admission. Other SABs were classified as healthcare associated or community acquired according to the definition proposed by Friedman et al. When available, strains of methicillin-resistant Staphylococcus aureus (MRSA) were analyzed by pulsed-field gel electrophoresis (PFGE).
Results:Eighty-two patients were considered as having community-acquired bacteremia according to the Centers for Disease Control and Prevention (CDC) classification. Of these 82 patients, 56% (46) had healthcare-associated SAB. MRSA prevalence was similar in patients with hospital-acquired and healthcare-associated SAB (41% vs 33%; P > .05), but significantly lower in the group with community-acquired SAB (11%; P < .03). PFGE of MRSA strains showed that most community-acquired and healthcare-associated MRSA strains were similar to hospital-acquired MRSA strains. On multivariate analysis, Friedman's classification was more effective than the CDC classification for predicting MRSA.
Conclusion:These results support the call for a new classification for community-acquired bacteremia that would account for healthcare received outside the hospital by patients with SAB.

Objective:
To demonstrate the effectiveness of the Charlson weighted index of comorbidity (WIC) for controlling comorbidity in prospective studies focusing on mortality in patients with Staphylococcus aureus bacteremia (SAB).
Design:Cohort study.
Setting:Two tertiary-care, university-affiliated hospitals in France.
Patients:One hundred sixty-six inpatients 18 years or older consecutively diagnosed with SAB from May 15, 2001, to May 15, 2002.
Methods:Patients were prospectively assessed and cases were followed by the infectious diseases consult service at least 3 months after effective antibiotic therapy completion. The Charlson WIC was computed and dichotomized into scores of fewer than 3 points and 3 or more points. Bacteremia source, acute complication due to SAB acquisition in the ICU, and inappropriate empiric antibiotic therapy were recorded. The endpoint was death due to SAB and overall mortality.
Results:In univariate analysis, the Charlson WIC was able to predict overall mortality and S. aureus-related death. The following variables were found to be independently predictive of mortality due to SAB using the Cox model: an acute complication due to S. aureus (OR, 8.9; CI95, 4 to 19.7; P < .001), a Charlson WIC score of 3 or more (OR, 3; CI95, 1.3 to 5.5; P = .006), and age (OR, 1.04; CI95, 1.009 to 1.07; P < .01).
Conclusions:Comorbidity contributes to death in patients with SAB. The Charlson WIC is a good predictor of mortality in this population and may be a useful instrument to control comorbidity in studies aiming to investigate risk factors for death due to bacteremia.

The thioredoxin action upon the 2-oxoacid dehydrogenase complexes is investigated by using different thioredoxins, both wild-type and mutated. The attacking cysteine residue of thioredoxin is established to be essential for the thioredoxin-dependent activation of the complexes. Mutation of the buried cysteine residue to serine is not crucial for the activation, but prevents inhibition of the complexes, exhibited by the Clamydomonas reinhardtii thioredoxin m disulfide. Site-directed mutagenesis of D26, W31, F/W12, and Y/A70 (the Escherichia coli thioredoxin numbering is employed for all the thioredoxins studied) indicates that both the active site and remote residues of thioredoxin are involved in its interplay with the 2-oxoacid dehydrogenase complexes. Sequences of 11 thioredoxin species tested biochemically are aligned. The thioredoxin residues at the contact between the α3/310 and α1 helices, the length of the α1 helix and the charges in the α2-β3 and β4-β5 linkers are found to correlate with the protein influence on the 2-oxoacid dehydrogenase complexes (the secondary structural elements of thioredoxin are defined according to Eklund H et al., 1991, Proteins 11:13–28). The distribution of the charges on the surface of the thioredoxin molecules is analyzed. The analysis reveals the species specific polarization of the thioredoxin active site surroundings, which corresponds to the efficiency of the thioredoxin interplay with the 2-oxoacid dehydrogenase systems. The most effective mitochondrial thioredoxin is characterized by the strongest polarization of this area and the highest value of the electrostatic dipole vector of the molecule. Not only the magnitude, but also the orientation of the dipole vector show correlation with the thioredoxin action. The dipole direction is found to be significantly influenced by the charges of the residues 13/14, 51, and 83/85, which distinguish the activating and inhibiting thioredoxin disulfides.

The personality profiles for youths with Prader-Willi, fragile-X, or Williams syndrome were compared to three matched groups attending regular schools. Using the California Child Q-Set (CCQ), both of the parents of the 39 children with Prader-Willi syndrome, 32 boys with fragile-X syndrome, 28 children with Williams syndrome, and children in the comparison groups provided independent personality descriptions in terms of the Big Five personality factors of Extraversion, Agreeableness, Conscientiousness, Emotional Stability, and Openness, along with Motor Activity and Irritability. Specific personality phenotypes for each of the three syndrome groups were found to be differentially related to parental behaviours (i.e. control and anger) and family contexts (i.e. experienced family stress, marital conflict, and parental consistency).

Thioredoxins are ubiquitous small-molecular-weight proteins (typically 100–120 amino-acid residues) containing an extremely reactive disulphide bridge with a highly conserved sequence -Cys-Gly(Ala/Pro)-Pro-Cys-. In bacteria and animal cells, thioredoxins participate in multiple reactions which require reduction of disulphide bonds on selected target proteins/enzymes. There is now ample biochemical evidence that thioredoxins exert very specific functions in plants, the best documented being the redox regulation of chloroplast enzymes. Another area in which thioredoxins are believed to play a prominent role is in reserve protein mobilization during the process of germination. It has been discovered that thioredoxins constitute a large multigene family in plants with different subcellular localizations, a unique feature in living cells so far. Evolutionary studies based on these molecules will be discussed, as well as the available biochemical and genetic evidence related to their functions in plant cells. Eukaryotic photosynthetic plant cells are also unique in that they possess two different reducing systems, one extrachloroplastic dependent on NADPH as an electron donor, and the other one chloroplastic, dependent on photoreduced ferredoxin. This review will examine in detail the latest progresses in the area of thioredoxin structural biology in plants, this protein being an excellent model for this purpose. The structural features of the reducing enzymes ferredoxin thioredoxin reductase and NADPH thioredoxin reductase will also be described. The properties of the target enzymes known so far in plants will be detailed with special emphasis on the structural features which make them redox regulatory. Based on sequence analysis, evidence will be presented that redox regulation of enzymes of the biosynthetic pathways first appeared in cyanobacteria possibly as a way to cope with the oxidants produced by oxygenic photosynthesis. It became more elaborate in the chloroplasts of higher plants where a co-ordinated functioning of the chloroplastic and extra chloroplastic metabolisms is required.
