Tidskriftsartikel (refereegranskat)abstract
- DIII-D physics research addresses critical challenges for the operation of ITER and the next generation of fusion energy devices. This is done through a focus on innovations to provide solutions for high performance long pulse operation, coupled with fundamental plasma physics understanding and model validation, to drive scenario development by integrating high performance core and boundary plasmas. Substantial increases in off-axis current drive efficiency from an innovative top launch system for EC power, and in pressure broadening for Alfven eigenmode control from a co-/counter-I p steerable off-axis neutral beam, all improve the prospects for optimization of future long pulse/steady state high performance tokamak operation. Fundamental studies into the modes that drive the evolution of the pedestal pressure profile and electron vs ion heat flux validate predictive models of pedestal recovery after ELMs. Understanding the physics mechanisms of ELM control and density pumpout by 3D magnetic perturbation fields leads to confident predictions for ITER and future devices. Validated modeling of high-Z shattered pellet injection for disruption mitigation, runaway electron dissipation, and techniques for disruption prediction and avoidance including machine learning, give confidence in handling disruptivity for future devices. For the non-nuclear phase of ITER, two actuators are identified to lower the L-H threshold power in hydrogen plasmas. With this physics understanding and suite of capabilities, a high poloidal beta optimized-core scenario with an internal transport barrier that projects nearly to Q = 10 in ITER at ∼8 MA was coupled to a detached divertor, and a near super H-mode optimized-pedestal scenario with co-I p beam injection was coupled to a radiative divertor. The hybrid core scenario was achieved directly, without the need for anomalous current diffusion, using off-axis current drive actuators. Also, a controller to assess proximity to stability limits and regulate β N in the ITER baseline scenario, based on plasma response to probing 3D fields, was demonstrated. Finally, innovative tokamak operation using a negative triangularity shape showed many attractive features for future pilot plant operation.

- Cell death is essential for a plethora of physiological processes, and its deregulation characterizes numerous human diseases. Thus, the in-depth investigation of cell death and its mechanisms constitutes a formidable challenge for fundamental and applied biomedical research, and has tremendous implications for the development of novel therapeutic strategies. It is, therefore, of utmost importance to standardize the experimental procedures that identify dying and dead cells in cell cultures and/or in tissues, from model organisms and/or humans, in healthy and/or pathological scenarios. Thus far, dozens of methods have been proposed to quantify cell death-related parameters. However, no guidelines exist regarding their use and interpretation, and nobody has thoroughly annotated the experimental settings for which each of these techniques is most appropriate. Here, we provide a nonexhaustive comparison of methods to detect cell death with apoptotic or nonapoptotic morphologies, their advantages and pitfalls. These guidelines are intended for investigators who study cell death, as well as for reviewers who need to constructively critique scientific reports that deal with cellular demise. Given the difficulties in determining the exact number of cells that have passed the point-of-no-return of the signaling cascades leading to cell death, we emphasize the importance of performing multiple, methodologically unrelated assays to quantify dying and dead cells.

The interaction between predation and competition : a review and synthesis
- 2002

Ingår i: Ecology Letters. ; 5:2, s. 302-315
-
Tidskriftsartikel (refereegranskat)abstract
- This review discusses the interface between two of the most important types of interactions between species, interspecific competition and predation. Predation has been claimed to increase, decrease, or have little effect on, the strength, impact or importance of interspecific competition. There is confusion about both the meaning these terms and the likelihood of, and conditions required for, each of these outcomes. In this article we distinguish among three measures of the influence of predation on competitive outcomes: short-term per capita consumption or growth rates, long-term changes in density and the probability of competitive coexistence. We then outline various theoretical mechanisms that can lead to qualitatively, distinct effects. of predators,. The qualitative effect of predators can depend both on the mechanism of competition and on the definition of competitive strength/impact. In assessing the empirical literature, we ask: (1) What definitions of competitive strength/impact have been assumed? (2) Does strong evidence exist to support one or more of the possible mechanisms that can produce a given outcome? (3) Do biases in the choice of organism or manipulation exist, and are they, likely, to have influenced the conclusions reached? We conclude by discussing several unanswered questions, and espouse a stronger interchange between empirical and theoretical approaches to this important question.

Tidskriftsartikel (refereegranskat)abstract
- There is great need for coordination around standards and best practices in neuroscience to support efforts to make neuroscience a data-centric discipline. Major brain initiatives launched around the world are poised to generate huge stores of neuroscience data. At the same time, neuroscience, like many domains in biomedicine, is confronting the issues of transparency, rigor, and reproducibility. Widely used, validated standards and best practices are key to addressing the challenges in both big and small data science, as they are essential for integrating diverse data and for developing a robust, effective, and sustainable infrastructure to support open and reproducible neuroscience. However, developing community standards and gaining their adoption is difficult. The current landscape is characterized both by a lack of robust, validated standards and a plethora of overlapping, underdeveloped, untested and underutilized standards and best practices. The International Neuroinformatics Coordinating Facility (INCF), an independent organization dedicated to promoting data sharing through the coordination of infrastructure and standards, has recently implemented a formal procedure for evaluating and endorsing community standards and best practices in support of the FAIR principles. By formally serving as a standards organization dedicated to open and FAIR neuroscience, INCF helps evaluate, promulgate, and coordinate standards and best practices across neuroscience. Here, we provide an overview of the process and discuss how neuroscience can benefit from having a dedicated standards body.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: To investigate the efficacy and safety of oral desmopressin in the treatment of nocturia in men. PATIENTS AND METHODS: Men aged >/=18 years with verified nocturia (>or=two voids/night) and nocturnal urine production greater than their maximum functional bladder capacity were recruited. A 3-week dose-titration phase established the optimum desmopressin dose (0.1, 0.2 or 0.4 mg). After a 1-week 'washout' period, patients who responded in the dose-titration period were randomized to receive the optimal dose of desmopressin or placebo in a double-blind design for 3 weeks. RESULTS: In all, 151 patients entered the double-blind period (86 treated with desmopressin, 65 with placebo). In the desmopressin group 28 (34%) patients and in the placebo group two (3%) patients (P<0.001) had fewer than half the number of nocturnal voids relative to baseline; the mean number of nocturnal voids decreased from 3.0 to 1.7 and from 3.2 to 2.7, respectively, reflecting a mean decrease of 43% and 12% (P<0.001). The mean duration of the first sleep period increased by 59% (from 2.7 to 4.5 h) in the desmopressin group, compared with an increase of 21% (from 2.5 to 2.9 h) in the placebo group (P<0.001). The mean nocturnal diuresis decreased by 36% (from 1.5 to 0.9 mL/min) in the desmopressin group and by 6% (from 1.7 to 1.5 mL/min) in the placebo group (P<0.001). The mean ratio of night/24-h urine volume decreased by 23% and 1% (P<0.001), and the mean ratio of night/day urine volume decreased by 27% and increased by 3% (P<0.001) for the desmopressin and placebo groups, respectively. In the double-blind treatment period, similar numbers of patients had adverse events; 15 (17%) patients in the desmopressin and 16 (25%) patients in the placebo group. Most adverse events were mild. Serum sodium levels were <130 mmol/L in 10 (4%) patients and this occurred during dose-titration. CONCLUSIONS: Orally administered desmopressin is an effective and well-tolerated treatment for nocturia in men.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: To characterize the utility of nitrotyrosine (NT) as a biomarker for arthritis and joint injury. Design: Synovial fluid, plasma, and urine from patients diagnosed with osteoarthritis (OA), rheumatoid arthritis (RA), anterior cruciate ligament (ACL) injury, meniscus injury and pseudogout, and knee-healthy volunteers were analyzed for concentrations of NT, nitrate and nitrite (NOx), matrix metalloproteinase (MMP)-3, MMP-1, MMP-9, more than 40 chemokines and cytokines. Results: In OA, plasma and synovial fluid NT were increased versus healthy volunteers. Synovial fluid to plasma NT ratios were elevated in OA patients. Synovial fluid from patients with ACL and meniscus injury and pseudogout had increased levels of NT (P < 0.001). In these samples, NT levels significantly correlated with ARGS-aggrecan neoepitope generated by aggrecanase cleavage of aggrecan (P <= 0.001), cross-linked C-telopeptides of type II collagen (P < 0.001), MMP-1 (P = 0.008), and MMP-3 (P <= 0.001). In RA, plasma NT decreased following 6 months of anti-tumor necrosis factor (TNF) treatment. For every 1.1% change in log(10) NT, there was a 1.0% change in the log(10) disease activity scores (DAS28-3 CRP). Both predicted and observed DAS28-3 CRP showed a robust linear relationship with NT. RA plasma NT positively correlated with CRP, MMP-3 and interferon gamma-induced protein 10. Conclusions: NT may serve as a useful biomarker for arthritis and joint injury. In RA, NT is highly correlated with several biomarkers and clinical correlates of disease activity and responds to anti-TNF therapy. (C) 2012 Osteoarthritis Research Society International.

Muscarinic receptors: their distribution and function in body systems, and the implications for treating overactive bladder
- 2006

Ingår i: British Journal of Pharmacology. - : Wiley. - 1476-5381 .- 0007-1188. ; 148:5, s. 565-578

Forskningsöversikt (refereegranskat)abstract
- 1 The effectiveness of antimuscarinic agents in the treatment of the overactive bladder (OAB) syndrome is thought to arise through blockade of bladder muscarinic receptors located on detrusor smooth muscle cells, as well as on nondetrusor structures. 2 Muscarinic M-3 receptors are primarily responsible for detrusor contraction. Limited evidence exists to suggest that M-2 receptors may have a role in mediating indirect contractions and/or inhibition of detrusor relaxation. In addition, there is evidence that muscarinic receptors located in the urothelium/suburothelium and on afferent nerves may contribute to the pathophysiology of OAB. Blockade of these receptors may also contribute to the clinical efficacy of antimuscarinic agents. 3 Although the role of muscarinic receptors in the bladder, other than M3 receptors, remains unclear, their role in other body systems is becoming increasingly well established, with emerging evidence supporting a wide range of diverse functions. Blockade of these functions by muscarinic receptor antagonists can lead to similarly diverse adverse effects associated with antimuscarinic treatment, with the range of effects observed varying according to the different receptor subtypes affected. 4 This review explores the evolving understanding of muscarinic receptor functions throughout the body, with particular focus on the bladder, gastrointestinal tract, eye, heart, brain and salivary glands, and the implications for drugs used to treat OAB. The key factors that might determine the ideal antimuscarinic drug for treatment of OAB are also discussed. Further research is needed to show whether the M-3 selective receptor antagonists have any advantage over less selective drugs, in leading to fewer adverse events.

-
Ingår i: Journal of Clinical Microbiology. - : American Society for Microbiology. - 0095-1137 .- 1098-660X. ; 55:5, s. 1454-1468

Tidskriftsartikel (refereegranskat)abstract
- A curated Web-based user-friendly sequence typing tool based on antimicrobial resistance determinants in Neisseria gonorrhoeae was developed and is publicly accessible (https://ngstar.canada.ca). The N. gonorrhoeae Sequence Typing for Antimicrobial Resistance (NG-STAR) molecular typing scheme uses the DNA sequences of 7 genes (penA, mtrR, porB, ponA, gyrA, parC, and 23S rRNA) associated with resistance to β-lactam antimicrobials, macrolides, or fluoroquinolones. NG-STAR uses the entire penA sequence, combining the historical nomenclature for penA types I to XXXVIII with novel nucleotide sequence designations; the full mtrR sequence and a portion of its promoter region; portions of ponA, porB, gyrA, and parC; and 23S rRNA sequences. NG-STAR grouped 768 isolates into 139 sequence types (STs) (n = 660) consisting of 29 clonal complexes (CCs) having a maximum of a single-locus variation, and 76 NG-STAR STs (n = 109) were identified as unrelated singletons. NG-STAR had a high Simpson's diversity index value of 96.5% (95% confidence interval [CI] = 0.959 to 0.969). The most common STs were NG-STAR ST-90 (n = 100; 13.0%), ST-42 and ST-91 (n = 45; 5.9%), ST-64 (n = 44; 5.72%), and ST-139 (n = 42; 5.5%). Decreased susceptibility to azithromycin was associated with NG-STAR ST-58, ST-61, ST-64, ST-79, ST-91, and ST-139 (n = 156; 92.3%); decreased susceptibility to cephalosporins was associated with NG-STAR ST-90, ST-91, and ST-97 (n = 162; 94.2%); and ciprofloxacin resistance was associated with NG-STAR ST-26, ST-90, ST-91, ST-97, ST-150, and ST-158 (n = 196; 98.0%). All isolates of NG-STAR ST-42, ST-43, ST-63, ST-81, and ST-160 (n = 106) were susceptible to all four antimicrobials. The standardization of nomenclature associated with antimicrobial resistance determinants through an internationally available database will facilitate the monitoring of the global dissemination of antimicrobial-resistant N. gonorrhoeae strains.

- Proton-pumping rhodopsins (PPRs) are photoactive retinal-binding proteins that transport ions across biological membranes in response to light. These proteins are interesting for light-harvesting applications in bioenergy production, in optogenetics applications in neuroscience, and as fluorescent sensors of membrane potential. Little is known, however, about how the protein sequence determines the considerable variation in spectral properties of PPRs from different biological niches or how to engineer these properties in a given PPR. Here we report a comprehensive study of amino acid substitutions in the retinal-binding pocket of Gloeobacter violaceus rhodopsin (GR) that tune its spectral properties. Directed evolution generated 70 GR variants with absorption maxima shifted by up to ± 80 nm, extending the protein's light absorption significantly beyond the range of known natural PPRs. While proton-pumping activity was disrupted in many of the spectrally shifted variants, we identified single tuning mutations that incurred blue and red shifts of 42 nm and 22 nm, respectively, that did not disrupt proton pumping. Blue-shifting mutations were distributed evenly along the retinal molecule while red-shifting mutations were clustered near the residue K257, which forms a covalent bond with retinal through a Schiff base linkage. Thirty eight of the identified tuning mutations are not found in known microbial rhodopsins. We discovered a subset of red-shifted GRs that exhibit high levels of fluorescence relative to the WT (wild-type) protein.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: To determine the impact of overactive bladder (OAB) symptoms on issues related to employment, social interactions, and emotional well-being in a population aged 40-64 years. SUBJECTS AND METHODS: The study comprised a cross-sectional population-based survey of 11 521 individuals aged 40-64 years, conducted in France, Germany, Italy, Spain, Sweden, and the UK. The survey involved a two-stage screening procedure. Initially, individuals with any lower urinary tract symptoms were identified. Those whose only symptom/(s) was suggestive of a urinary tract infection, stress incontinence, or prostate obstruction were excluded from further study. Respondents were asked questions about the impact that their symptoms had on their emotional well-being, social interactions and productivity at home and at work. RESULTS: Of those with OAB, approximately 32% (1272) reported that having these symptoms made them feel depressed, and 28% reported feeling very stressed. There were statistically significant differences in reported feelings of stress and depression when OAB symptoms were stratified by OAB with incontinence (OAB+) vs those with OAB with no incontinence (OAB-), with values for emotional stress of OAB+ 36.4% vs OAB- 19.6%, for depression of OAB+ 39.8% vs OAB- 23.3%. Participants with OAB+ were significantly more likely than those with OAB- to express worry about having accidents and concern about participating in activities away from home because of their bladder symptoms. In addition, those with OAB+ were significantly more likely to report that these bladder symptoms were a source of great concern and made them feel uncomfortable in social situations compared to those with OAB-. Men were significantly more likely than women to report OAB+ having an impact on their daily work life, including worry about interrupting meetings, impact on decisions about work location and hours, and voluntary termination or early retirement. This effect was primarily in men reporting OAB+. CONCLUSION: OAB symptoms have a significant effect on the emotional well-being and productivity of those affected, both at home and at work.

- Introduction. The prevalence of sexual dysfunction, including erectile dysfunction (ED), is greater in men with lower urinary tract symptoms (LUTS), including overactive bladder (OAB), than in men without LUTS. Aim. To evaluate the prevalence of ED, the impact of urinary symptoms on sexual activity and sexual enjoyment, and sexual satisfaction in men with OAB. Methods. A nested case-control analysis was performed on data from a subset of men with (cases) and without (controls) OAB frequency-matched for age (5-year age strata) and country from the EPIC study. Respondents were asked about OAB symptoms (using the 2002 International Continence Society [ICS] definitions) and sexual activity. Sexually active respondents were asked about ED, sexual enjoyment, and overall satisfaction with their sex lives. Conditional logistic regression was used to assess factors associated with ED. Main Outcome Measures. The percentage of cases and controls reporting ED, a reduction in the frequency of sexual activity or enjoyment of sexual activity because of urinary symptoms, and overall satisfaction with their sex lives was determined for cases and controls. Results. A total of 502 cases and 502 controls were matched for age strata and country. Significantly more cases (14%) reported reduced sexual activity because of urinary symptoms compared with controls (4%; P

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: Estimate the prevalence of urinary incontinence (UI), overactive bladder (OAB), and other lower urinary tract symptoms (LUTS) among men and women in five countries using the 2002 International Continence Society (ICS) definitions. METHODS: This population-based, cross-sectional survey was conducted between April and December 2005 in Canada, Germany, Italy, Sweden, and the United Kingdom using computer-assisted telephone interviews. A random sample of men and women aged >/= 18 yr residing in the five countries and who were representative of the general populations in these countries was selected. Using 2002 ICS definitions, the prevalence estimates of storage, voiding, and postmicturition LUTS were calculated. Data were stratified by country, age cohort, and gender. RESULTS: A total of 19,165 individuals agreed to participate; 64.3% reported at least one LUTS. Nocturia was the most prevalent LUTS (men, 48.6%; women, 54.5%). The prevalence of storage LUTS (men, 51.3%; women, 59.2%) was greater than that for voiding (men, 25.7%; women, 19.5%) and postmicturition (men, 16.9%; women, 14.2%) symptoms combined. The overall prevalence of OAB was 11.8%; rates were similar in men and women and increased with age. OAB was more prevalent than all types of UI combined (9.4%). CONCLUSIONS: The EPIC study is the largest population-based survey to assess prevalence rates of OAB, UI, and other LUTS in five countries. To date, this is the first study to evaluate these symptoms simultaneously using the 2002 ICS definitions. The results indicate that these symptoms are highly prevalent in the countries surveyed.

Prevalence, Severity, and Symptom Bother of Lower Urinary Tract Symptoms among Men in the EPIC Study: Impact of Overactive Bladder
- 2009

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Lower urinary tract symptoms (LUTS) are prevalent among men. OBJECTIVE: To describe the prevalence, severity, and symptom bother of LUTS in all men and men with overactive bladder (OAB) symptoms in the EPIC study. DESIGN, SETTING, AND PARTICIPANTS: A secondary analysis of data from EPIC, a multinational population-based survey of 19 165 adults, was performed. Current International Continence Society definitions were used for individual LUTS and OAB; OAB cases were defined as men reporting urgency. MEASUREMENTS: Participants were asked about the presence of individual LUTS and associated symptom bother. LUTS severity was measured using the International Prostate Symptom Score (IPSS). RESULTS AND LIMITATIONS: There was substantial overlap of storage, voiding, and postmicturition symptoms among all men (n=7210) and in men with OAB symptoms (n=502); men with OAB symptoms were more likely to experience multiple LUTS subtypes. Among both populations, nocturia was the most commonly reported symptom, except for urgency (the hallmark symptom) among men with OAB symptoms; terminal dribble and sensation of incomplete emptying were the most common voiding and postmicturition symptoms. The prevalence of all LUTS increased with age among the general population; only storage LUTS increased with age among men with OAB symptoms. Number of LUTS and mean IPSS increased with age in both populations but were higher among men with OAB symptoms at all ages; the proportion reporting moderate-severe LUTS was higher than the general population (30% vs 6%). The proportion of men with OAB symptoms reporting symptom bother increased with urgency severity and severity and number of LUTS. LUTS severity may have been underestimated by the IPSS, which does not assess incontinence. CONCLUSIONS: Men with LUTS commonly experience coexisting storage, voiding, and postmicturition symptoms, emphasizing the need for comprehensive urologic assessments. Men with OAB symptoms reported more LUTS and greater severity than the general population. Symptom bother was related to number of LUTS and urgency severity.
