Sliced Fluorescence Imaging Techniques for the Study of Photo‐initiated Dynamic Processes in Bulbs
Authors: Chen Yu‐wei , Chen Kuo‐mei 
Published: August 2013

AbstractTo study photo‐initiated dynamic processes in bulbs, sliced fluorescence imaging techniques have been developed to obtain quantum‐state resolved information on the speed and angular distributions of reaction products, and their angular momentum polarization characteristics. For fluorescent chemical species, an unconventional experimental arrangement can generate a two‐dimensional projection of the Newton sphere from a single photolysis center. Consequently, image blurring for photo‐initiated experiments in bulbs can be dramatically diminished. A combination of optical‐optical (or infrared‐optical) double resonance excitation scheme and the fluorescence imaging detection method warrants a novel technique to acquire three‐dimensional sliced fluorescence images of scattering products. A theoretical framework, which employs a double Legendre moment analysis on the central sliced images, has been developed to determine differential cross sections and kinetic energy release of co‐products in photo‐initiated dynamic processes. Experimental images of collisional relaxations of CN photofragments from disequilibrium to equilibrium are presented to illustrate the distinctive advantage of the present method in comparison with other imaging and spectroscopic techniques.

AbstractPseudomonas aeruginosa is an opportunistic pathogen capable of group behaviors including swarming motility and biofilm formation. Swarming motility plays an important role in the bacterium's spread to new environments, attachment to surfaces, and biofilm formation. Bacterial biofilm is associated with many persistent infections and increased resistance to antibiotics. In this study, we tested the effect of a 2‐alkyl‐4(1H)‐quinolone (AHQ) signal, the Pseudomonas quinolone signal (PQS) on P. aeruginosa swarming and biofilm formation. Our results show that PQS repressed the swarming motility of P. aeruginosa PAO1. Such repression was independent of its cognate receptor PqsR and was not related to changes in the flagellae, type IV pili or the production of the surface‐wetting agent rhamnolipid surfactant. While PQS did not affect twitching motility in PAO1, a pqsR deletion abolished twitching motility, indicating that pqsR is required for twitching motility. Our results also indicate that the enhancement of biofilm formation by PQS is at least partially dependent on the GacAS‐Rsm regulatory pathway but does not involve the las or rhl QS systems.

Published: August 2013

ABSTRACTThe kinetics of the reactions of 1‐methylimidazole with iodoethane, 1‐iodobutane, 1‐bromobutane, 1‐bromohexane, 1‐bromooctane resulting in the formation of corresponding 1‐alkyl‐3‐methylimidazolium halide ionic liquids in acetonitrile and cyclopentanone solutions has been studied in a wide range of concentrations and degrees of conversion. The studied reactions were found to follow the SN2 rate law in the dilute solutions. The significant deviations from the simple SN2 rate law observed at higher concentrations of the reactants were assigned to the concentration dependence of activity coefficients for the reactants and the transition states. The experimental data were processed with the conductor‐like screening model–segment activity coefficient (COSMO‐SAC) model and the Scatchard–Hildebrand equation. The latter was found to provide somewhat better description of the experimental results; however, the former has a wider predictive ability. The Arrhenius activation energies and the activation enthalpies were calculated for the investigated systems. The rate constants at infinite dilution were obtained for a large number of 1‐haloalkane + 1‐methylimidazole + solvent systems with the use of the COSMO‐SAC model. It was demonstrated that the rate constants of the studied reactions in various non‐hydrogen‐bonding solvents can be estimated from a correlation with the Hildebrand solubility parameter.

AbstractAimsStudies of overactive bladder (OAB) have shown urothelial/suburothelial changes and increased bladder afferents, while in the brain the frontal micturition area that normally suppresses the bladder is deactivated. It has been unclear whether anticholinergic medication could reverse this suppression. To address this question, we performed a real‐time NIRS (near‐infrared spectroscopy)‐urodynamic study in OAB patients before and after the administration of an anticholinergic agent, tolterodine.MethodsWe recruited 13 OAB patients in our outpatient clinic (9 males, 4 female; mean age 73 years). Before and after the administration of 4 mg/day tolterodine for 3 months, all patients completed the OAB‐symptom scale and a NIRS‐urodynamics examination. Cerebral changes in the oxy‐hemoglobin concentration (oxy‐Hb) were sampled. Concentration changes in oxy‐Hb were calculated based on a modified Beer–Lambert approach.ResultsTolterodine significantly reduced the OAB patients' nighttime frequency (P < 0.05) and increased their first‐sensation volume (290–359 ml, P < 0.01). The number of patients with detrusor overactivity did not lessen significantly (11–9). The real‐time NIRS‐urodynamic study showed that, during slow bladder filling between start and bladder capacity, tolterodine significantly activated the right frontal micturition area of the OAB patients (P < 0.05). The activation was prominent in Brodmann's area 8, 9, 10 of the prefrontal cortex.ConclusionsTolterodine reduced bladder sensation together with a significant activation of the frontal micturition area of OAB patients, particularly Brodmann's area 8, 9, 10 of the right prefrontal cortex. This activation seems to be a secondary phenomenon, since tolterodine does not easily penetrate the blood–brain barrier. Neurourol. Urodynam. 33:1110–1115, 2014. © 2013 Wiley Periodicals, Inc.

Published: August 2013

ABSTRACTAimsIn human urinary bladder, beta3‐ARs play an important role in promoting detrusor relaxation during the storage phase of the micturition cycle. The present study investigated whether a Trp64Arg polymorphism of the gene encoding the beta3‐AR is associated with overactive bladder (OAB) syndrome.MethodsThis study involved 100 women with OAB and 101 healthy control women without OAB. Hair root samples were obtained from all subjects and used for beta3‐AR gene analysis. Polymerase chain reaction (PCR)–restriction fragment length polymorphism (RFLP) analysis was performed to analyze a polymorphism in the gene of Trp64Arg.ResultsThe overall frequency of the 64Arg variant (heterozygous plus homozygous) in OAB patients was 47% and significantly higher than the frequency of 22.8% found in non‐OAB control women. Within OAB patients, numbers of micturitions per day, urgency episodes per day, and urgency incontinence episodes per day in the 64Arg variant carriers were not significantly different from those in the normal gene carriers.ConclusionsThis study shows that the Trp64Arg polymorphism in the beta3‐AR gene is weakly but significantly associated with OAB syndrome.

The effect of angiotensin inhibition on urinary incontinence: Data from the national health and nutrition examination survey (2001–2008)
Authors: Elliott Christopher S. , Comiter Craig V. 
Published: August 2013

AbstractIntroductionLocal renin–angiotensin systems exist within the genitourinary tract, specifically in the bladder and urethra. Experimental data suggest that angiotensin receptor blockade with either angiotensin converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) decreases both detrusor overactivity and urethral sphincter tone leading to decreased urge incontinence (UUI) and increased stress urinary incontinence (SUI). This has not been examined in a human population.MethodsData from the National Health and Nutrition Examination Survey (NHANES) was accessed for the years 2001–2008. Multivariate logistic regression was used for modeling.ResultsWe studied 8,754 females and 8,886 males who met inclusion criteria. Use of ACE inhibitors or ARBs was not associated with a change in SUI in either men or women. In men, use of an ACE inhibitor or ARB was associated with a statistically significant 25–30% decrease in UUI (monthly or any urge incontinence). A similar, albeit non‐significant trend was also seen for daily and weekly UUI. Other antihypertensive medications (diuretics, beta‐blockers, calcium‐channel blockers) were not associated with a decrease in UUI. In subanalysis, duration of ACE inhibitor or ARB use did not alter the strength of the effect on UUI nor did an elevated prostate specific antigen (PSA) level (used as a surrogate for bladder outlet obstruction due to benign prostatic hypertrophy). ACE inhibitor and ARB use did not affect UUI rates in women, though did show a trend for improvement in nulliparous women without SUI.ConclusionAngiotensin receptor blockade may be a viable treatment approach for the treatment of UUI, especially in men.

AbstractAimsTo study micturition and bladder overactivity in female rats after chronic treatment with the fatty acid amide hydrolase (FAAH) inhibitor oleoyl ethyl amide (OEtA).MethodsSprague–Dawley rats received daily subcutaneous injections of OEtA (0.3 mg/kg), or vehicle for 2 weeks. Cystometries, organ bath studies, Western blot, and immunofluorescence were then used. Expressions of FAAH, cannabinoid 1 and 2 receptors (CB1 and CB2), mitogen‐activated protein kinase (MAPK), vesicular acetyl choline‐transporter protein (VAChT), and calcitonin gene‐related peptide (CGRP) were evaluated.ResultsAt baseline, OEtA‐treated rats had higher values (P < 0.05) of micturition intervals (MI) and volumes (MV), bladder capacity (BC), threshold pressure, and flow pressure than vehicle controls. Intravesical PGE2 reduced MI, MV, and BC, and increased basal pressure and the area under the curve in all rats. However, these urodynamic parameters were altered less by intravesical PGE2 in OEtA‐treated rats (P < 0.05 vs. vehicle controls). Compared to vehicle controls, detrusor from OEtA‐treated rats had larger contractions to carbachol at 10–0.1 µM, but no difference in Emax was recorded. FAAH, CB1, CB2, VAChT, or CGRP was similarly expressed in bladders from all rats. In separate experiments, intravesical OEtA increased mucosal expression of phosphorylated MAPK.ConclusionsChronic FAAH inhibition altered sensory urodynamic parameters and reduced bladder overactivity. Even if it cannot be excluded that OEtA may act on central nervous sensory pathways to contribute to these effects, the presence of FAAH and CB receptors in the bladder and activation of intracellular signals for CB receptors by intravesical OEtA suggest a local role for FAAH in micturition control.

Reflective function as a mediator between childhood adversity, personality disorder and symptom distress
Authors: Chiesa Marco , Fonagy Peter 
Published: August 2013

ABSTRACTA growing body of literature has indicated the central role of childhood adversity for the development in later life of personality disorder (PD) and psychiatric distress. In this investigation, we examine the role of reflective function (RF) as a mediator between childhood adversity, subsequent development of PD and psychiatric morbidity. We tested the hypothesis that adversity leads to decreased RF, which in turn is associated with PD, and both increase the likelihood of psychiatric distress. The study sample consisted of 234 individuals, drawn from a clinical PD group (n = 112) and one demographically matched non‐psychiatric group (n = 122) using a shared battery of measures, which included the Structured Clinical Interview for DSM‐IV, the Symptom Checklist‐90‐R and the Adult Attachment Interview, which was used to assess RF levels. The results indicated that childhood adversity predicted low level of RF, which in turn was associated with PD onset later in life. A combination of different early adverse experiences had a significantly greater impact on lowering RF scores than experiencing either neglect or abuse alone. Mediation analyses confirmed that RF was a significant mediator between adversity and PD diagnoses and between adversity and psychiatric distress. Copyright © 2013 John Wiley & Sons, Ltd.
Depression, anxiety, and somatic symptoms in older cancer patients: a comparison across age groups
Authors: Cohen Miri 
Published: August 2013

AbstractBackgroundPrevious studies have reported that older cancer patients experience lower psychological distress than younger patients, but most prior studies do not differentiate between age groups within the ‘older’ category.AimThe aim of this study was to assess the intensity of the symptoms of depression, anxiety, and somatic symptoms among different age groups of older cancer patients.MethodsParticipants were composed of 321 cancer patients 60 years and older, who were divided into three age groups: 60–69, 70–79, and 80+ years. The participants answered the Brief Symptom Inventory‐18, which included subscales for depression, anxiety, and somatic symptoms and the cancer‐related problem list, in addition to providing personal and cancer‐related details.ResultsDepressive, anxiety, and somatic symptoms and cancer‐related problems were lowest in the 70–79 years age group and highest in the 80+ years age group. Comparisons between pairs of groups showed significant differences between each of the groups in Brief Symptom Inventory total scores and between the 80+ years age group and the other two groups in regard to depressive symptoms and cancer‐related problems. Differences, related to anxiety and somatic symptoms, were significant for the 70–79 year olds, in comparison with the youngest and oldest groups. Intensity of symptoms was explained by older age, higher number of cancer‐related problems, female gender, and lower income.ConclusionNonlinear relations exist between age and psychological symptoms, which is in line with the postponement of age‐related health and functional decline in the modern era. These results suggest that the study of psychological reactions to cancer should examine differences between age groups among older cancer patients. Copyright © 2013 John Wiley & Sons, Ltd.

Published: August 2013

AbstractBACKGROUNDObservational studies suggest an inverse association between vitamin E and risk of prostate cancer, particularly aggressive tumors. However, three large randomized controlled trials have reported conflicting results. Thus, we examined circulating vitamin E and vitamin E‐related genes in relation to risk of high‐grade prostate cancer and prostate cancer recurrence among men initially diagnosed with clinically organ‐confined disease.METHODSWe measured circulating α‐ and γ‐tocopherol and genotyped 30 SNPs in SOD1, SOD2, SOD3, TTPA, and SEC14L2 among 573 men with organ‐confined prostate cancer who underwent radical prostatectomy. We examined associations between circulating vitamin E, genotypes, and risk of high‐grade prostate cancer (Gleason grade ≥ 8 or 7 with primary score ≥ 4; n = 117) using logistic regression, and risk of recurrence (56 events; 3.7 years median follow‐up) using Cox proportional hazards regression.RESULTSCirculating γ‐tocopherol was associated with an increased risk of high‐grade prostate cancer (Q4 v. Q1 odds ratio [OR] = 1.87; 95% confidence intervals [CI]: 0.97–3.58; Ptrend = 0.02). The less common allele in SOD3 rs699473 was associated with an increased risk of high‐grade disease (T > C: OR = 1.40, 95% CI: 1.04–1.89). Two independent SNPs in SOD1 were inversely associated with prostate cancer recurrence in additive models (rs17884057 hazard ratio [HR] = 0.49, 95%CI: 0.25–0.96; rs9967983 HR = 0.62, 95% CI: 0.40–0.95).CONCLUSIONSAmong men with clinically organ‐confined prostate cancer, genetic variation in SOD may be associated with risk of high‐grade disease at diagnosis and disease recurrence. Circulating γ‐tocopherol levels may also be associated with an increased risk of high‐grade disease at diagnosis. Prostate 73:1786–1795, 2013. © 2013 Wiley Periodicals, Inc.
Nanocrystalline and microcrystalline diamond stacking structure as an insulating material deposited on large area
Authors: Yamada Takatoshi , Hasegawa Masataka 
Published: August 2013

AbstractA stacking structure of nanocrystalline diamond (NCD) and microcrystalline diamond (MCD) was proposed to use as an insulating layer for silicon on insulator (SOI) substrates with large wafer size, in order to improve both break down field and thermal conductivity. NCD with a thickness of about 200 nm was deposited by the surface wave microwave plasma chemical vapor deposition (CVD) on silicon (Si) substrate after seeding process and then MCD (6 µm in thickness) was deposited on the as‐grown NCD surface by hot filament CVD. It was confirmed, by scanning electron microscope observation, formation of the stacking structure of NCD and MCD. From measurements of current versus voltage characteristics, the break down field of the stacking structure was three times higher than that of MCD layer. Thermal conductivities of the self‐standing of stacking structure measured by thermo‐reflectance measurement were from 320 to 500 W mK−1, which was almost the same as the thermal conductivities of the MCD layers.
