Air Pollution and Risk of Parkinson’s Disease in a Large Prospective Study of Men

Background: Exposure to air pollution has been implicated in a number of adverse health outcomes, and the effect of particulate matter (PM) on the brain is beginning to be recognized. Objectives: We aimed to examine whether exposure to PM air pollution is related to risk of Parkinson's disease (PD) in the Health Professionals Follow-up Study (HPFS), a large prospective cohort of U.S. men. Methods: We prospectively followed 50,352 men in the HPFS, a large prospective cohort of U.S. men, and identified 550 incident PD cases. Cumulative average exposure to various size fractions of PM [PM10 (≤10μm microns in diameter), PM2.5 (≤2.5μm in diameter), and PM2.5–10 (between 2.5 and 10μm in diameter)] up to 2 years before the onset of PD was estimated using a spatiotemporal model by linking each participant’s place of residence throughout the study with location-specific PM levels. We used multivariable Cox proportional hazards models to independently estimate the risk of PD associated with each size fraction of PM. Results: In models adjusted for age, smoking, region, and population density, we did not observe statistically significant associations between exposure to PM and PD risk. In analyses considering cumulative average PM exposure, the comparing the top to the bottom quintile of PM exposure was 0.85 [95% confidence interval (CI): (0.63, 1.15)] for PM10, 0.97 [95% CI: (0.72, 1.32)] for PM2.5, and 0.88 [95% CI: (0.64, 1.22)] for hazard ratio (HR) PM2.5–10. The results did not change markedly when restricted to men who did not move during the study or when stratified by smoking status or population density. Conclusions: In this study, we found no evidence that exposure to air pollution is a risk factor for PD in men. https://doi.org/10.1289/EHP259
Twenty‐Five‐Year Alcohol Consumption Trajectories and Their Association With Arterial Aging: A Prospective Cohort Study

Background Emerging evidence suggests that arterial stiffness, an important marker of cardiovascular health, is associated with alcohol consumption. However, the role of longer‐term consumption patterns in the progression of arterial stiffness over time remains unclear. A longitudinal cohort design was used to evaluate the association between alcohol consumption over 25 years and subsequent changes in arterial stiffness. Methods and Results Data (N=3869; 73% male) were drawn from the Whitehall II cohort study of British civil servants, in which participants completed repeat pulse wave velocity assessments of arterial stiffness across a 4‐ to 5‐year interval. Repeated alcohol intake measurements were used to categorize participants into alcohol consumer types, accounting for longitudinal variability in consumption. Sex‐stratified linear mixed‐effects modeling was used to investigate whether drinker types differed in their relationship to pulse wave velocity and its progression over time. Males with consistent long‐term heavy intake >112 g of ethanol/week had significantly higher baseline pulse wave velocity (b=0.26 m/s; P=0.045) than those who drank consistently moderately (1–112 g of ethanol/week). Male former drinkers showed significantly greater increases in arterial stiffness longitudinally compared to consistently moderate drinkers (b=0.11 m/s; P=0.009). All associations were nonsignificant for females after adjustment for body mass index, heart rate, mean arterial pressure, diabetes mellitus, high‐density lipoprotein, and triglycerides. Conclusions This work demonstrates that consistently heavy alcohol consumption is associated with higher cardiovascular risk, especially among males, and also provides new insights into the potential impact of changes in drinking levels over time. It discusses the additional insights possible when capturing longitudinal consumption patterns in lieu of reliance on recent intake alone.

PARS: a web server for the prediction of Protein Allosteric and Regulatory Sites

The regulation of protein activity is a key aspect of life at the molecular level. Unveiling its details is thus crucial to understanding signalling and metabolic pathways. The most common and powerful mechanism of protein-function regulation is allostery, which has been increasingly calling the attention of medicinal chemists due to its potential for the discovery of novel therapeutics. In this context, PARS is a simple and fast method that queries protein dynamics and structural conservation to identify pockets on a protein structure that may exert a regulatory effect on the binding of a small-molecule ligand.
Two new species of Phrynopus (Anura, Strabomantidae) from high elevations in the Yanachaga-Chemillén National park in Peru (Departamento de Pasco)

Abstract We describe two new species of Phrynopus from a cloud forest of the Cordillera Yanachaga, Yanachaga-Chemillén National Park in Peru and describe and document the first clutch and case of parental care for a species of Phrynopus. One of the new species of Phrynopus is described based on two females (SVL 19.1–21.0 mm) which were found in leaf litter and moss layer in a cloud forest at 2900 m elevation. This new species is most similar to Phrynopus bracki. The second new species of Phrynopus was found in the transitional formation between cloud forest and wet puna at 3000 m elevation. Its description is based on a single female (SVL 20.7 mm) that was observed guarding nine eggs under moss. This new species is most similar to Phrynopus nicoleae. The eggs had a diameter of 5.7–5.8 mm (n = 3) and froglets when hatched a SVL of 6.2–6.5 mm (n = 3). Sympatric anurans include Gastrotheca sp. , Pristimantis aniptopalmatus, Pristimantis bromeliaceus, Pristimantis sp. , and Rhinella yanachaga.
Routing in pocket switched networks

Pocket switched networks (PSNs) provide a new networking paradigm that takes advantage of human mobility to distribute data. Due to the frequent and long-duration disruptions of network links, routing in PSNs is nontrivial. In this article, we first outline the challenges of PSN routing. After that, we summarize the behavioral traits of human beings employed by existing PSN routing schemes and give a brief survey on the state-of-the- art PSN routing techniques. Finally, we analyze the characteristics of existing PSN routing protocols and present some open problems that may foster future research on PSN routing.
Natural history of Mycobacterium avium complex lung disease in untreated patients with stable course

Little is known about the long-term natural history of Mycobacterium avium complex lung disease (MAC-LD) in untreated patients with stable course. The aim of this study was to investigate the natural course of untreated stable MAC-LD, with a focus on factors associated with clinical deterioration, spontaneous sputum conversion and prognosis. Of 488 patients diagnosed with MAC-LD between 1998 and 2011, 305 patients (62.5%) showed progressive MAC-LD resulting in treatment initiation within 3 years of diagnosis and 115 patients (23.6%) exhibited stable MAC-LD for at least 3 years with a median follow-up duration of 5.6 years. Patients with stable MAC-LD were more likely to have higher body mass index and less systemic symptoms at initial diagnosis compared with patients with progressive MAC-LD, while positive sputum acid-fast bacilli smear, fibrocavitary type and more extensive disease in radiological findings were more associated with progressive MAC-LD. Of the untreated patients with stable MAC-LD, 51.6% underwent spontaneous sputum conversion, with younger age, higher body mass index and negative sputum acid-fast bacilli smear at initial diagnosis found to be predictors of this occurrence. Advanced age, fibrocavitary type and abnormal pulmonary function were negative prognostic factors for survival in patients with stable MAC-LD. Host predisposing factors are relatively more important than microbiological factors in stable MAC-LD patients http://ow.ly/nf9N306AQd0
Somatoform disorder in primary care: The influence of co‐morbidity with anxiety and depression on health care utilization

RATIONALE, AIMS, AND OBJECTIVES Patients with somatoform disorders are frequent attenders in primary and secondary care. While co-morbid mental disorders, especially depression and anxiety, are frequently present, there is controversy on whether mental co-morbidity leads to higher health care utilization (HCU). The present paper investigates the influence of co-morbid depressive and anxiety disorders on primary, specialized somatic and mental HCU in primary care patients with somatoform disorders. Additionally, we investigated the predictive value of self-rated health and illness perception on HCU. METHODS Patients in 19 primary care practices were screened with the Patient Health Questionnaire, and patients at high risk for somatoform disorders were assessed using the Composite International Diagnostic Interview. N = 71 patients with somatoform disorders were analysed. We analysed whether having one vs two co-morbidities (depression and/or anxiety), self-rated health, and illness perception were predictors for primary, specialized somatic and mental HCU using binominal and hierarchical regression analyses. RESULTS Having both co-morbid depressive and anxiety disorder predicted higher primary HCU (IRR = 1.96, 95% CI, 1.30-2.93), and increased the odds of being in mental health care (OR = 5.16, 95% CI, 1.10-24.20), while only one co-morbidity did not. No differences were found for specialized somatic HCU. Illness perception and self-rated health did not predict HCU. CONCLUSION Not a single but only the presence of multiple co-morbidities predicts primary and mental HCU in patients with somatoform disorder. Health care utilization might be essentially influenced by the associated psychological distress, which should be considered in treatment.
Bride Price and Female Education

We document an important consequence of bride price, a payment made by the groom to the bride’s family at marriage. Revisiting Indonesia’s school construction program, we find that among ethnic groups without the custom, it had no effect on girls’ schooling. Among ethnic groups with the custom, it had large positive effects. We show (theoretically and empirically) that this is because a daughter’s education, by increasing the amount of money parents receive at marriage, generates an additional incentive for parents to educate their daughters. We replicate these findings in Zambia, a country that had a similar large-scale school construction program.
Effect of dietary calcium, phosphorus, chloride, and zeolite on the development of tibial dyschondroplasia.

The effect of synthetic zeolite was investigated on the development of tibial dyschondroplasia in young broilers fed diets in which the dietary levels of calcium, phosphorus, and chloride ranged from adequate to deficient. In the first two experiments the calcium level was maintained at . 65% and four combinations were fed of . 30% and . 15% chloride and . 75% and . 50% phosphorus with and without 1% zeolite. Feeding the high phosphorus diet caused a high incidence of tibial dyschondroplasia that was lowered by feeding 1% zeolite. In both experiments the feeding of zeolite at a low level of dietary phosphorus caused a significant lowering of 16-day weight and bone ash. In the third experiment, when diets containing all combinations of . 65% and . 80% calcium and . 50% and . 60% phosphorus were fed, the addition of 1% zeolite caused a significant lowering of the 16-day weight, bone ash, and incidence, score, and percentage severe tibial dyschondroplasia. Once again as in the previous two experiments, there was a significant interaction between dietary phosphorus level and zeolite and 16-day weight and bone ash. Feeding zeolite significantly decreased phytate phosphorus retention.
Human papillomavirus E6 and Myc proteins associate in vivo and bind to and cooperatively activate the telomerase reverse transcriptase promoter

The papillomavirus E6 protein binds and directs the ubiquitin-dependent degradation of the p53 tumor suppressor protein. Independent of this p53-degradative function, however, E6 induces cellular telomerase activity. This increase in enzyme activity reflects E6-enhanced transcription of the human telomerase reverse transcriptase (hTERT) catalytic subunit, but the molecular basis for this transactivation is unknown. In the present study, we demonstrate that E6/Myc interactions regulate hTERT gene expression. Mad protein, a specific antagonist of Myc, repressed E6-mediated transactivation of the hTERT promoter and this repression was relieved by Myc overexpression. The proximal Myc/ Max-binding element (E-box) in the hTERT promoter was the major determinant of both E6 and Myc responsiveness in keratinocytes. E6 did not alter Myc protein expression or Myc/Max association, and the induction of hTERT by Myc/E6 was independent of Myc phosphorylation at Thr-58/Ser-62 within the transactivation domain. However, immunoprecipitation studies demonstrated that endogenous Myc protein coprecipitated with E6 protein and chromatin immunoprecipitation analyses demonstrated that both E6 and Myc proteins bound to a minimal 295-bp hTERT promoter. Only the “high-risk” E6 proteins bound to the hTERT promoter, consistent with their preferential ability to induce telomerase. The observation that E6 associates with Myc complexes and activates a Myc-responsive gene identifies a mechanism by which this oncogene can modulate cell proliferation and differentiation.
Cross-linkers both drive and brake cytoskeletal remodeling and furrowing in cytokinesis

Cytokinesis and other cell shape changes are driven by the actomyosin contractile cytoskeleton. The molecular rearrangements that bring about contractility in non-muscle cells are currently debated. Specifically, both filament sliding by myosin motors, as well as cytoskeletal crosslinking by myosins and non-motor crosslinkers, are thought to promote contractility. Here, we examined how the abundance of motor and non-motor crosslinkers controls the speed of cytokinetic furrowing. We built a minimal model to simulate the contractile dynamics of the C. elegans zygote cytokinetic ring. This model predicted that intermediate levels of non-motor crosslinkers would allow maximal contraction speed, which we found to be the case for the scaffold protein anillin, in vivo. Our model also demonstrated a non-linear relationship between the abundance of motor ensembles and contraction speed. In vivo, thorough depletion of non-muscle myosin II delayed furrow initiation, slowed F-actin alignment, and reduced maximum contraction speed, but partial depletion allowed faster-than-expected kinetics. Thus, both motor and non-motor crosslinkers promote cytokinetic ring closure when present at low levels, but act as a brake when present at higher levels. Together, our findings extend the growing appreciation for the roles of crosslinkers, but reveal that they not only drive but also brake cytoskeletal remodeling.
Evaluation of low-template DNA profiles using peak heights

Abstract In recent years statistical models for the analysis of complex (low-template and/or mixed) DNA profiles have moved from using only presence/absence information about allelic peaks in an electropherogram, to quantitative use of peak heights. This is challenging because peak heights are very variable and affected by a number of factors. We present a new peak-height model with important novel features, including over- and double-stutter, and a new approach to dropin. Our model is incorporated in open-source R code likeLTD. We apply it to 108 laboratory-generated crime-scene profiles and demonstrate techniques of model validation that are novel in the field. We use the results to explore the benefits of modeling peak heights, finding that it is not always advantageous, and to assess the merits of pre-extraction replication. We also introduce an approximation that can reduce computational complexity when there are multiple low-level contributors who are not of interest to the investigation, and we present a simple approximate adjustment for linkage between loci, making it possible to accommodate linkage when evaluating complex DNA profiles.
ABO and D typing and alloantibody screening in marrow samples: relevance to intraosseous blood transfusion

Blood transfusion through the intraosseous route is gaining popularity in emergency medicine. Pretransfusion peripheral blood (PB) samples are usually not available in these patients, leading to discrepancies in blood group typing and a possible delay in transferring to group‐specific blood products. The aim of this study was to assess the feasibility of ABO and D typing and red blood cell alloantibody screening in marrow (BM) samples.
A new motor screening assessment for children at risk for motor disorders: construct validity

ABSTRACT Objective: To develop a motor screening assessment and provide preliminary evidence of its psychometric properties. Methods: A sample of 365 elementary school students was assessed, with structural equation modeling applied to obtain evidence of the adequacy of the factor structure of the motor screening assessment. As well, differential item functioning was used to evaluate whether various identifiable subgroups of children (i.e., sex and grade) perform particular tasks differently. Results: Overall, girls obtained higher scores than boys while, for both sexes, the assessment scores increased with age. Furthermore, differential item function analysis revealed that the precision of the test was highest for those with moderate to low motor performance, suggesting that this tool would be appropriate for identifying individuals with movement difficulties. Conclusion: Although further tests of its psychometric properties are required, the motor screening assessment appears to be a reliable, valid, and quickly-administered tool for screening children's movements.
Seasonal Abundance of Mango Fruit Flies (Diptera: Tephritidae) and Ecological Implications for Their Management in Mango and Cashew Orchards in Benin (Centre & North)

ABSTRACT We report the results of a large-scale (six orchards) and long-term (5-yr) study on seasonal population fluctuations of fruit flies (Diptera Tephritidae) in mango (2005–2009) and cashew (2007–2009) orchards in the Borgou Department, Benin. During the five consecutive years of mango fruit fly monitoring, 25 tephritid species were captured including three species of Bactrocera, 11 of Ceratitis, and 11 of Dacus, which is represented by 2,138,150 specimens in mango orchards. We observed significant differences in Bactrocera dorsalis (Hendel) counts between “high” and “low” mango production years from 2005 to 2008 but not in Ceratitis cosyra (Walker) counts. The native species, C. cosyra, the most abundant species during the dry season, peaked beginning of May, while the exotic species, B. dorsalis, the most abundant species during the rainy season, peaked in June. Preliminary results underlined the role of nine species of wild hosts and seven species of cultivated ones around mango orchards that played an important role in maintaining B. dorsalis in this Sudan zone all year round. The presence of C. cosyra stretched over 9 mo. During the first 14 wk of tephritid monitoring on cashew orchards situated near mango orchards, most flies (62%) were captured in traps positioned in cashew orchards, showing the strong interest of an early fly control on cashew before the mango season. According to these results, in the Sudan zone, effective and compatible control methods as proposed by the IPM package validated by the West African Fruit Fly Initiative project against mango fruit flies are proposed for a large regional tephritid control program in same zones ofWest Africa.
Horizontal-flow anaerobic immobilized sludge (HAIS) reactor for paper industry wastewater treatment

Immobilized cell reactors are known to permit the continuous operation without biomass washout and also for increasing the time available for cells` catalytic function in a reaction or in a series of reactions. Several cell immobilization supports have been used in different reactors for anaerobic wastewater treatment, such as: agar gel, acrylamide, porous ceramic, and polyurethane foam besides the self-immobilized biomass from UASB reactors. However, the results are not conclusive as to the advantages of these different reactors with different supports as compared to other anaerobic reactor configurations. This paper describes a new anaerobic attached growth reactor configuration, herein referred as horizontal-flow anaerobic immobilized sludge (HAIS) reactor and presents the results of its performance test treating kraft paper industry wastewater. The reactor configuration was conceived aiming to increase the ratio useful volume/total volume by lowering the volume for gas separation. The HAIS reactor conception would permit also to incorporate the reactor hydrodynamic characteristics in its design criteria if the flow pattern could be approximated as plug-flow.
A Method for Assessing Auditory Spatial Analysis in Reverberant Multitalker Environments.

BACKGROUND Deficits in spatial hearing can have a negative impact on listeners' ability to orient in their environment and follow conversations in noisy backgrounds and may exacerbate the experience of hearing loss as a handicap. However, there are no good tools available for reliably capturing the spatial hearing abilities of listeners in complex acoustic environments containing multiple sounds of interest. PURPOSE The purpose of this study was to explore a new method to measure auditory spatial analysis in a reverberant multitalker scenario. RESEARCH DESIGN This study was a descriptive case control study. STUDY SAMPLE Ten listeners with normal hearing (NH) aged 20-31 yr and 16 listeners with hearing impairment (HI) aged 52-85 yr participated in the study. The latter group had symmetrical sensorineural hearing losses with a four-frequency average hearing loss of 29.7 dB HL. DATA COLLECTION AND ANALYSIS A large reverberant room was simulated using a loudspeaker array in an anechoic chamber. In this simulated room, 96 scenes comprising between one and six concurrent talkers at different locations were generated. Listeners were presented with 45-sec samples of each scene, and were required to count, locate, and identify the gender of all talkers, using a graphical user interface on an iPad. Performance was evaluated in terms of correctly counting the sources and accuracy in localizing their direction. RESULTS Listeners with NH were able to reliably analyze scenes with up to four simultaneous talkers, while most listeners with hearing loss demonstrated errors even with two talkers at a time. Localization performance decreased in both groups with increasing number of talkers and was significantly poorer in listeners with HI. Overall performance was significantly correlated with hearing loss. CONCLUSIONS This new method appears to be useful for estimating spatial abilities in realistic multitalker scenes. The method is sensitive to the number of sources in the scene, and to effects of sensorineural hearing loss. Further work will be needed to compare this method to more traditional single-source localization tests.
Modeling for automated test generation - a comparison

In this contribution, we compare and analyze different methodologies of modeling for test generation. As an example, we use an industrial requirement specification given in natural language, which describes a safety function in a hybrid car. We model these requirements with three different paradigms and languages: as the specification imposes several timing constraints, we choose Abstract State Machines, Timed Automata and UML2 State Machines to formalize the given requirements. From these models, we employ different tools for generating test cases, and compare the resulting test suites with respect to coverage and fault detection capabilities. We discuss the process of designing the models and the implications for professional software testing.
