Valve replacement for aortic stenosis normalizes subendocardial function in patients with normal ejection fraction.

AIMS Long-standing aortic stenosis (AS) causes various degrees of left ventricular (LV) dysfunction, which may improve after valve replacement. The aim of this study was to assess the nature of LV subendocardial abnormalities in AS and their response to valve replacement (AVR). METHODS AND RESULTS We studied 41 consecutive symptomatic patients (age 64 +/- 13 years) with severe AS, normal LV ejection fraction (EF), but no obstructive coronary artery disease before, a week after AVR, and 6 months after AVR. LV subendocardial function was studied from recordings of long-axis M-mode (amplitude), tissue-Doppler (myocardial velocities) and speckle tracking (myocardial strain) echocardiographic techniques. Results were compared with those from 20 age- and gender-matched controls. In patients, LV dimensions and markers of asynchrony, total isovolumic time (t-IVT), and Tei index were not different from controls before AVR and remained unchanged afterwards. LV lateral long-axis amplitude, as well as lateral and septal systolic velocities and strain, were reduced (P < 0.001 for all) and E/E' was modestly raised. Lateral long-axis amplitude, systolic and diastolic velocities normalized within a week of AVR but strain lagged behind until 6 months later. The reduced septal long-axis amplitude remained permanently unchanged (NS) despite the early normalization of its systolic velocities (P < 0.001) and strain (P < 0.001). LV mass normalized at 6 months after AVR (P < 0.005). CONCLUSIONS In patients with severe AS and maintained LV ejection fraction, subendocardial function is globally abnormal showing reduced amplitude of motion, velocities, and strain. The different response of its components suggests an evidence for differential reverse remodelling, irrespective of myocardial mass regression.
Functional Components of Public Expenditure, Fiscal Consolidations, and Economic Activity

This paper analyses how the functional components of public expenditure and spending-driven consolidations affect the economic growth, unemployment and income inequality. A dynamic panel data LSDVC estimator is employed over a sample of 15 European Union countries during the period 1990-2012. The empirical results show that real GDP growth decreases when fiscal austerity measures are implemented, especially if they are spending-driven. Cuts in public expenditure undermine economic growth, namely if they slash spending on public order, recreation and education. Spending cuts on education, in particular, affect the investment in human capital, harming not only growth but also economic, social and human development. The unemployment rate also proved to be significantly boosted when austerity measures restrict spending on education, while income inequality rises when social protection expenditures are cut.
100-Gbit/s logic IC using 0.1-/spl mu/m-gate-length InAlAs/InGaAs/InP HEMTs

High-speed electrical multiplexing and demultiplexing are keys in optical fiber communication systems. In the last few years, multiplexing operations at over 80 Gbit/s have been reported for selector ICs using InP HEMT and InP HBT technologies. The record operating speed is, however, still 90 Gbit/s, which was characterized only by means of a waveform observation on digitizing sampling oscilloscope. This paper describes 100-Gbit/s multiplexing and demultiplexing error-free logic operations in InP HEMT technology.
Qualitative exploration of relationships between peers in residential addiction treatment

Relationships between peers are often considered central to the therapeutic process, yet there is relatively little empirical research either on the nature of peer-to-peer relationships within residential treatment or on how those relationships generate positive behaviour change or facilitate recovery. In this paper, we explore relationships between peers in residential addiction treatment, drawing upon the concept of social capital to frame our analyses. Our study was undertaken during 2015 and 2016 in two English residential treatment services using the same therapeutic community-informed model of treatment. We conducted 22 in-depth interviews with 13 current and 9 former service residents. All interviews were audio-recorded, transcribed verbatim, coded in MAXQDA, and analysed using Iterative Categorisation. Residents reported difficult relationship histories and limited social networks on entry into treatment. Once in treatment, few residents described bonding with their peers on the basis of shared experiences and lifestyles. Instead, interpersonal differences polarised residents in ways that undermined their social capital further. Some senior peers who had been in residential treatment longer acted as positive role models, but many modelled negative behaviours that undermined others' commitment to treatment. Relationships between peers could generate feelings of comfort and connectedness, and friendships developed when residents found things in common with each other. However, residents more often reported isolation, loneliness, wariness, bullying, manipulation, intimidation, social distancing, tensions and conflict. Overall, relationships between peers within residential treatment seemed to generate some positive but more negative social capital; undermining the notion of the community as a method of positive behaviour change. With the caveat that our data have limitations and further research is needed, we suggest that residential treatment providers should more routinely open the "black box" of "community as method" to consider the complex and dynamic nature of the relationships and social capital inside.
Influence of Inositol Pyrophosphates on Cellular Energy Dynamics

Inositol pyrophosphates are implicated in coordination of cell proliferation and metabolism. With its high-energy phosphate bonds, adenosine triphosphate (ATP) is the main intracellular energy carrier. It also functions in most signaling pathways, as a phosphate donor or a precursor for cyclic adenosine monophosphate. We show here that inositol pyrophosphates participate in the control of intracellular ATP concentration. Yeasts devoid of inositol pyrophosphates have dysfunctional mitochondria but, paradoxically, contain four times as much ATP because of increased glycolysis. We demonstrate that inositol pyrophosphates control the activity of the major glycolytic transcription factor GCR1. Thus, inositol pyrophosphates regulate ATP concentration by altering the glycolytic/mitochondrial metabolic ratio. Metabolic reprogramming through inositol pyrophosphates is an evolutionary conserved mechanism that is also preserved in mammalian systems.
Description of a 96-well plate assay to measure cytochrome P4503A inhibition in human liver microsomes using a selective fluorescent probe.

The standard method to evaluate CYP3A inhibition is to study the conversion of the specific CYP3A probe testosterone to its 6 beta-hydroxy metabolite in human liver microsomes, in the absence and presence of potential inhibitors. Quantification of the 6 beta-hydroxy metabolite is achieved by HPLC resulting in a tedious and time-consuming assay. In order to increase the P450 inhibition throughput, efforts were made to find a CYP3A probe that would produce a fluorescent metabolite. This paper reports the discovery of DFB as a potential CYP3A fluorescent probe. DFB was significantly metabolized in human microsomes (approximately 1-2 nmol/(min. mg protein)) to give the fluorescent compound DFH. The involvement of CYP3A in the metabolism of DFB was determined using multiple approaches. First, incubations conducted with microsomes made from cell lines expressing single CYPs (Gentest Supersomes) indicated that CYP3A played a major role in the metabolism of DFB. Secondly, immunoinhibition studies conducted with CYP3A antibody resulted in >95% inhibition of DFB metabolism in HLM. Thirdly, inhibition studies with specific CYP1A1, 1A2, 2C8/9, 2C19, 2D6, and 2E1 chemical inhibitors did not suppress DFB activity in HLM. However, ketoconazole, miconazole, nicardipine, and nifedipine, all known CYP3A inhibitors, completely abolished the formation of DFH in HLM. The potency of several inhibitors determined using DFB and testosterone as CYP3A probes was consistent (R = 0.98). Finally, a good agreement was obtained for the formation of DFH and production of 6 beta-hydroxytestosterone when DFB and testosterone were incubated separately with various human liver microsome preparations (R = 0.94, N = 11). In order to use DFH as a fluorescent CYP3A marker in a 96-well plate format, it was important to remove the excess of NADPH at the end of the incubation because the fluorescence of NADPH interferes with DFH detection. This was achieved by adding oxidized glutathione and glutathione reductase to convert NADPH to NADP(+) which is not fluorescent. The liquid-handling steps were fully automated in a 96-well plate format and a template was designed to generate IC(50) curves and to address potential fluorescent interferences from the test compounds. The assay was found to be reproducible (intraday variability <10% and interday variability indicated less than a 2-fold variation in the IC(50) values) and is now routinely used in our laboratory to evaluate CYP3A inhibition of NCEs.
Offshore Profit Shifting and Domestic Productivity Measurement

Official statistics display a significant slowdown in U.S. aggregate productivity growth that begins in 2004. We show how offshore profit shifting by U.S. multinational enterprises affects GDP and, thus, productivity measurement. Under international statistical guidelines, profit shifting causes part of U.S. production generated by multinationals to be excluded from official measures of U.S. production. Profit shifting has increased significantly since the mid-1990s, resulting in lower measures of U.S. aggregate productivity growth. We construct an alternative measure of value added that adjusts for profit shifting. The adjustments raise aggregate productivity growth rates by 0.09 percent annually for 1994-2004, 0.24 percent annually for 2004-2008, and lowers annual aggregate productivity growth rates by 0.09 percent after 2008. Our adjustments mitigate, but do not eliminate, the measured productivity slowdown. The adjustments are especially large in R&D-intensive industries, which most likely produce intangible assets that facilitate profit shifting. The adjustments boost value added in these industries by as much as 8 percent in the mid-2000s.
Management and Outcome of Patients With Langerhans Cell Histiocytosis and Single‐Bone CNS‐Risk Lesions: A Multi‐Institutional Retrospective Study

Children with Langerhans cell histiocytosis (LCH) and single‐bone CNS‐risk lesions have been reported to be at increased risk of diabetes insipidus (DI), central nervous system neurodegeneration (CNS‐ND), and recurrence of disease. However, it is unknown whether the addition of chemotherapy or radiotherapy changes outcomes in these patients.
Degeneration, regeneration, and cicatrization after fat grafting: dynamic total tissue remodeling during the first 3 months.

BACKGROUND Fat grafting is promising, but clinical outcomes are not always predictable. The mechanisms of tissue revascularization/regeneration, and tissue necrosis and subsequent absorption/fibrosis of the graft, are poorly understood. METHODS An autologous inguinal fat pad was transplanted under the scalp of mice, and detailed cellular events during the first 3 months were investigated with immunohistochemistry. RESULTS Except for the most superficial surviving zone, death of all adipocytes was confirmed at 1 week. Perilipin-positive small new adipocytes appeared at 1 week and peaked in number at 4 weeks in the regenerating zone (the second zone). In the most central necrotizing zone, adipogenesis did not occur and many inflammatory cells were observed after 2 weeks. CD34+/Ki67+ proliferating adipose stem/progenitor cells were seen at 1 to 4 weeks, but the majority of proliferating cells were MAC2+ monocytes/macrophages. Although CD206+ M1 macrophages surrounded oil droplets for phagocytosis, CD206+ M2 macrophages appeared in areas where adipocyte replacement failed and formed multiple layers for cicatrization of oil drop spaces. Adipogenesis was complete by 12 weeks, but stabilization of nonregenerated areas was still ongoing at that time. Lipid droplets derived from dead adipocytes were absorbed slowly and thus aided adipose remodeling by maintaining the space until adipocyte regeneration. CONCLUSIONS Dynamic remodeling after fat grafting was confirmed. Adipocyte fate differed, depending on the microenvironment: intact survival, replacement with a new adipocyte, or replacement with cicatrization/oil cyst. This detailed understanding will help refine surgical grafting procedures and postoperative evaluation.
Anaerobic fitness in children with asthma: Adaptation to maximal intermittent short exercise

Nineteen asthmatic boys (aged 13.4 years, 25–75 percentile: 11.5–15.1 years) performed short bouts of maximal exercise (force‐velocity test) to test their anaerobic fitness and tolerance of maximal anaerobic exercise. Fourteen healthy boys (aged 13.9 years, 25–75 percentile: 11.6–15.7 years) matched for anthropometric characteristics including lean body mass (LBM), pubertal stage, and weekly physical activity formed a control group. The maximal anaerobic power (Wana) was measured during the force‐velocity test. The maximal oxygen uptake (V′ O 2max ) was assessed during a standard graded exercise test. Pre‐ and post‐exercise pulmonary function was measured by body plethysmography.
Aggressive therapy for neurosarcoidosis: long-term follow-up of 48 treated patients.

BACKGROUND Neurosarcoidosis (NS) is a relatively rare neurologic disorder for which no accepted treatment guidelines are available. Treatment with corticosteroids has been described as the primary means of controlling progressive symptoms. However, some physicians have recently advocated early intervention with alternative immunosuppressive therapies in patients who present with disabling symptoms. OBJECTIVE To investigate our experience during the last decade regarding alternative immunosuppressive treatments, including corticosteroids and alternative therapies, in patients with NS. DESIGN Observational, retrospective, consecutive case series with longitudinal follow-up. SETTING Allegheny Neurological Clinic. Patients Seventy-eight patients with sarcoidosis were evaluated and classified as having possible, probable, or definite NS according to accepted criteria. Five cases of isolated NS were also included. MAIN OUTCOME MEASURES Patients with probable, definite, or isolated NS were scored before treatments and at final follow-up using estimated modified Rankin scores and the Disease Steps in Multiple Sclerosis scales. RESULTS Forty-three patients were categorized as having either definite or probable NS according to accepted criteria and an additional 5 as having isolated NS. Thirty patients were categorized as having possible NS and were not included in the analysis of treatment response. Patients had a mean +/- SD number of visits of 7.2 +/- 6.4 and were followed up for a mean +/- SD of 44.1 +/- 43.6 months. Twenty patients were treated with pulse and/or maintenance corticosteroids alone. Twenty-six patients were treated with alternative immunosuppressive medications, with 23 of them receiving these medications at the time of diagnosis or within 6 months of the diagnosis of NS. Of the patients treated with alternative immunosuppressive therapies, 18 (69%) improved, 4 (15%) remained stable, and 4 (15%) worsened (including 1 death). Of the patients treated with corticosteroids alone, 7 (35%) improved, 11 (55%) remained stable, and 2 (10%) worsened. Two patients received no treatment. CONCLUSIONS Approximately half of all patients with NS seen at our clinic were believed to have disabling disease and to be at high risk for disease progression. These high-risk patients were treated with corticosteroids plus alternative immunosuppressive therapy, and favorable outcomes were obtained in almost all patients. Toxic effects related to treatments were minimal.

Construction and characterization of a potential live oral carrier-based vaccine against Vibrio cholerae O139

The rfb region from Vibrio cholerae O139 strain MO45 was cloned from cosmid gene banks established in Escherichia coli HB101, using an immunoblot assay for screening of the correct clones. Immunoblot analysis of lipopolysaccharide (LPS) preparations revealed the presence of two types of positive clones: (i) those expressing only a short core-linked O polysaccharide (SOPS) and (ii) those also expressing a highly polymerized capsular polysaccharide (CPS) not bound to the E. coli K-12 LPS core. In addition, the latter clones appear to contain a locus which may encode a putative regulator of SOPS and CPS chain length. Further characterization in E. coli showed that CPS constitutes a barrier against large particles such as the bacteriophage Ffm but not against bacteriophage lambda or P1. In addition, a portion of the K-12 LPS core may not be substituted with SOPS. Loci associated with the two clonal types were transferred into V. cholerae CH19, an rfbAB deletion mutant of CVD103-HgR deficient in the production of the homologous Inaba O polysaccharide. This resulted in the stable expression of SOPS, alone or together with CPS, that was indistinguishable from that of wild-type V. cholerae O139. Strains CH25 and CH26, which correspond to CH19 bearing the V. cholerae O139 rfb region integrated into the chromosome, were found to be genetically stable and essentially identical to the parent CVD103-HgR with respect to physiological properties such as cell motility, mercury resistance, toxicity, and production of the cholera toxin B subunit. Rabbits immunized with CH25 elicited high titers of anti-O139 SOPS- and CPS-specific serum antibodies. These strains possess characteristics desirable in candidate live oral vaccines against V. cholerae O139.
Visual impairment and road traffic accidents among drivers in Jimma Town, Southwest Ethiopia.

BACKGROUND Vision play a vital role in driving where good and efficient visual functioning of the driver is essential. Any significant loss of visual function will diminish a driver's ability to operate a motor vehicle safely and will thus contribute to road traffic injury. However, there is little evidence indicating that defects of vision alone cause road traffic accidents. OBJECTIVE To determine the impact of visual impairment and other factors on road traffic accident among vehicle drivers. METHODS A cross-sectional descriptive study was conducted on 249 sampled drivers in Southwest Ethiopia. A pretested interviewer led questionnaire was used for interview and vision tests were done using Snellen's acuity chart and Ishihara pseudo-isochromatic plates. Statistical analyses were performed using SPSS version 16.0. RESULTS The mean age of drivers was 33.6 years (SD +/- 10.3). The relative frequency of self reported road traffic accident was 15.3%. The prevalence of uncorrected binocular visual impairment was 1.6% and there was a significant association between visual impairment and road traffic accident (P < 0.05). Uncorrected refractive error was seen in 7.6% and 8.8% of drivers in the right and left eyes respectively, and 3.2% of them had vision less than what is required to obtain driving license (visual acuity of 6/12). None of the drivers with refractive errors were wearing appropriate corrections. Color vision impairment was seen in 1.6% of the drivers. A significant proportion (9.6%) of the drivers did not have eye exam for their driving license. CONCLUSION Uncorrected binocular visual impairment was strongly associated with road traffic accident. There is need for consistent inspection and screening, strict rules and regulations of licensing and health education for drivers to minimize road traffic accident.
The Prevalence of Borderline Personality among Buprenorphine Patients

Objective: In this study, we examined the prevalence of borderline personality disorder (BPD) in a sample of patients seeking outpatient treatment with buprenorphine for opioid addiction. Method: To assess for BPD, we used three self-report surveys in a consecutive study sample. Results: Of the 111 participants who completed all three measures of BPD, 49 (44.1%) exceeded the cut-off score indicative of BPD. Conclusions: Among individuals who are addicted to opioids and seeking treatment with buprenorphine, the prevalence of BPD, as mutually confirmed by three self-report measures, is quite high.
Radiographic examination of mesiodens and their associated complications.

OBJECTIVES To examine mesiodens with regard to their status, their influence on adjacent teeth and their alteration during the follow-up period. METHODS From retrospective reviews of all patients who visited our institution from 1990-2001, we identified 200 patients (256 mesiodentes) who were shown to have mesiodentes on the basis of a periapical radiograph, a panoramic radiograph or an axial radiograph. RESULTS The number of supernumerary teeth was one in 146 cases (73%), two in 52 cases (26%) and three in 2 cases (1%). Of 256 mesiodentes, the direction of the crown of the mesiodens was inverted in 172 (67%), in a normal direction in 69 (27%) and in a horizontal direction with regard to the tooth axis in 15 (6%). Of the 147 mesiodentes for which axial radiography was performed, 131 (89%) were located at a palatal site against the dental arch, 16 (11%) overlapped the dental arch and none were at a labial site. Of our 200 cases, a delay of eruption of the permanent central incisor was seen in 12 (6%), malposition or rotation of the central incisor in 5 (2.5%) and dentigerous cyst formation arising from mesiodens in 22 (11%). Marked movement of the mesiodens was seen in 10 cases during the follow-up period of 5-7 years. Some complication arising from mesiodens was seen in 19.5% of all cases in our research. CONCLUSION Although mesiodentes are not caused by malocclusion, they may cause it. A long period of impaction of mesiodentes may bring about dentigerous cyst formation or movement of the mesiodentes.
