BACKGROUND: Prognostic scores and models of illness severity are useful both clinically and for research. The aim of this study was to develop two prognostic models for the prediction of long-term (6 months) and 28-day mortality of postoperative critically ill patients with faecal peritonitis (FP). METHODS: Patients admitted to intensive care units with faecal peritonitis and recruited to the European GenOSept study were divided into a derivation and a geographical validation subset; patients subsequently recruited to the UK GAinS study were used for temporal validation...

Robert Ehrlich
In The Long Week-End Wilfred Bion focuses on his emotional distress during the first twenty-one years of his life. Rarely employing psychoanalytic terminology, he attempts to explore his emotional experience directly, struggling to find a language that could capture the complexity of inner life. Central to The Long Week-End is his desire to communicate how easily he could feel unintelligent, inept, weak, ashamed, guilty, angry, frightened, and cowardly in various settings. This self-criticism at times undermines his theoretical stance in this work, as he emphasizes the importance of doubt and uncertainty when attempting to comprehend most dimensions of experience...

Previously our laboratory documented increases in calvaria bone volume and thickness in mice exposed to 15 days of spaceflight aboard the NASA Shuttle mission STS-131. However, the tissues were not processed for gene expression studies to determine what bone formation pathways might contribute to these structural adaptations. Therefore, this study was designed to investigate both the structural and molecular changes in mice calvariae after a longer duration of spaceflight. The primary purpose was to determine the calvaria bone volume and thickness of mice exposed to 30 days of spaceflight using micro-computed tomography for comparison with our previous findings...

Improving the nutritional and health properties of food products, e.g. infant milk formula, by the addition of functional ingredients is of primary importance. This study focused on bioactive milk polar lipids (PLs) recovered from dietary sources that are of increasing interest. The chemical compositions of buttermilks and butter serums were determined and the modulation of the fatty acid composition of milk PLs was investigated. Butter serums contain a higher amount of milk PLs than buttermilks (88 vs. 13-18g/kg dry matter), with a higher proportion of sphingomyelin (34 vs...

Mechanical loading is necessary for the development and maintenance of the musculoskeletal system. Removal of loading via microgravity, paralysis, or bed rest leads to rapid loss of muscle mass and function; however, the molecular mechanisms that lead to these changes are largely unknown, particularly for the spaceflight (SF) microgravity environment. Furthermore, few studies have explored these effects on the shoulder, a dynamically stabilized joint with a large range of motion; therefore, we examined the effects of microgravity on mouse shoulder muscles for the 15-d Space Transportation System (STS)-131, 13-d STS-135, and 30-d Bion-M1 missions...

The author contends that, contrary to the usual perception that Winnicott followed a linear progression "through pediatrics to psychoanalysis," Winnicott's vision was always a psychoanalytic one, even during his early pediatric work. His place in the development of psychoanalytic theory is highlighted, and the author discusses such key Winnicottian concepts as transitional space, the false self, and the use of the object. Winnicott's unique approach to the form and value of analytic interpretation is particularly emphasized, and his thoughts on the treatment of depression are also addressed, as well as his distinction between regression and withdrawal...

Harsh environmental conditions including microgravity and radiation during prolonged spaceflights are known to alter hepatic metabolism. Our studies have focused on the analysis of possible changes in metabolic pathways in the livers of mice from spaceflight project "Bion-M 1". Mice experienced 30 days of spaceflight with and without an additional re-adaption period of seven days compared to control mice on Earth. To investigate mice livers we have performed proteomic profiling utilizing shotgun mass spectrometry followed by label-free quantification...

The photoreactivity of plant activator benzo(1,2,3)thiadiazole-7-carbothioic acid S-methyl ester (BTH), commonly named acibenzolar-S-methyl, was studied on the surfaces of glass, paraffinic wax films, and apple leaves. Experiments were carried out in a solar simulator using pure and formulated BTH (BION). Surface photoproducts were identified using liquid chromatography coupled with electrospray ionization and high-resolution Orbitrap mass spectrometry, while volatile photoproducts were characterized using an online thermal desorption system coupled to a gas chromatography-mass spectrometry (GC-MS) system...

It is common knowledge that the same phenomena can be viewed in a variety of ways. This paper considers the implications of a constellation observed in some adult patients who have increasingly reminded the author of some of the children of latency age with whom he has also worked. In the literature these patients may also have been thought about in terms of 'defences of the self' (Fordham), patients who are 'difficult to reach' (Joseph), 'psychic retreats' (Steiner), and those who make 'attacks on linking' (Bion)...

Various neurological and psychiatric diseases lead to alterations in cortical serotonergic activity as one of their underlying processes. However, the electrophysiological implication of changes in serotonergic activity remains a matter of investigation. In this study, we investigated whether brain serotonergic activity influences the excitability-related phenomenon known as cortical spreading depression (CSD). CSD parameters (propagation velocity, and amplitude and duration of the DC-shift) was evaluated in rats that received two treatments that increased cortical serotonergic activity, electrical stimulation of the raphe nuclei and subcutaneous injection of a selective serotonin reuptake inhibitor, sumatriptan...

Nanopore technology has been extensively investigated for analysis of biomolecules, and a success story in this field concerns DNA sequencing using a nanopore chip featuring an array of hundreds of biological nanopores (BioNs). Solid-state nanopores (SSNs) have been explored to attain longer lifetime and higher integration density than what BioNs can offer, but SSNs are generally considered to generate higher noise whose origin remains to be confirmed. Here, we systematically study low-frequency (including thermal and flicker) noise characteristics of SSNs measuring 7 to 200 nm in diameter drilled through a 20-nm-thick SiNx membrane by focused ion milling...

The plant activator acibenzolar-S-methyl (BTH) undergoes phototransformation when exposed to solar radiation. Here we investigated the changes in its elicitation properties on BY-2 tobacco cells at different stages of the photochemical reaction. Both pure BTH and formulated BTH were irradiated in controlled conditions to achieve different extents of conversion. Both pure BTH (900 μM) and Bion(®) (0.4 g.L(-1)) induced BY-2 cell death, but BTH photoconverted to an extent of 25 ± 3% lowered the cell death rate...

The safety of space flight is challenged by a severe loss of skeletal muscle mass, strength, and endurance that may compromise the health and performance of astronauts. The molecular mechanisms underpinning muscle atrophy and decreased performance have been studied mostly after short duration flights and are still not fully elucidated. By deciphering the muscle proteome changes elicited in mice after a full month aboard the BION-M1 biosatellite, we observed that the antigravity soleus incurred the greatest changes compared with locomotor muscles...

The weightless environment during spaceflight induces site-specific bone loss. The 30-day Bion-M1 mission offered a unique opportunity to characterize the skeletal changes after spaceflight and an 8-day recovery period in mature male C57/BL6 mice. In the femur metaphysis, spaceflight decreased the trabecular bone volume (-64% vs. Habitat Control), dramatically increased the bone resorption (+140% vs. Habitat Control) and induced marrow adiposity invasion. At the diaphysis, cortical thinning associated with periosteal resorption was observed...

Animals are an essential component of space exploration and have been used to demonstrate that weightlessness does not disrupt essential physiological functions. They can also contribute to space research as models of weightlessness-induced changes in humans. Animal research was an integral component of the 30-day automated Russian biosatellite Bion-M 1 space mission. The aim of the hemodynamic experiment was to estimate cardiovascular function in mice, a species roughly 3000 times smaller than humans, during prolonged spaceflight and post-flight recovery, particularly, to investigate if mice display signs of cardiovascular deconditioning...

This is a paper showing how a concept central to the work of Wilfred Bion, and one of Klein's important recommendations concerning the practice of analysis with adults and small children, can both be seen in the light of Freud's earliest formulation of the origin of anxiety and the mother's first responses to her infant in distress. In the paper I suggest that these clinically influential concepts of Klein and Bion show an underlying consistency and affinity with Freud's early ideas about the management of anxiety in the mother-infant relationship, described in two of his pre-psychoanalytic writings, How Anxiety Originates (1894b), and The Project for a Scientific Psychology (1950 [1895])...

Microgravity as well as chronic muscle disuse are two causes of low back pain originated at least in part from paraspinal muscle deconditioning. At present no study investigated the complexity of the molecular changes in human or mouse paraspinal muscles exposed to microgravity. The aim of this study was to evaluate longissimus dorsi adaptation to microgravity at both morphological and global gene expression level. C57BL/N6 male mice were flown aboard the BION-M1 biosatellite for 30 days (BF) or housed in a replicate flight habitat on ground (BG)...

Chymosin is the major enzyme used in cheesemaking but latex enzymes are also used. The aim of this work was to characterize the composition and the structure of dairy gel obtained by an extract of Calotropis procera leaves in comparison with those obtained by chymosin. The biochemical and mineral compositions of the curds and the cheese yields obtained by using Calotropis procera extract or chymosin were relatively similar. Quantitative and qualitative evaluations of proteolysis after milk coagulation, determined by the non-protein nitrogen content and chromatography coupled to mass spectrometry, indicated that Calotropis procera extract was more proteolytic than chymosin and that κ-casein was proteolyzed...

Importance: Latent cytomegalovirus (CMV) infection is present in more than half the adult population, and a viral reactivation (ie, when the virus becomes measurable in body fluids such as blood) can occur in up to one-third of these individuals during episodes of critical illness. Objective: To determine whether antiviral therapy is safe and effective for preventing CMV reactivation in a general population of critically ill patients. Design, Setting, and Participants: A single-center, open-label, randomized, controlled clinical trial recruited 124 CMV-seropositive patients undergoing mechanical ventilation for at least 24 hours in the intensive care unit between January 1, 2012, and January 31, 2014...
