Asma, abitudini e stile di vita "Analisi retrospettiva di un campione di pazienti asmatici seguito in ambulatorio di terzo livello"

Growing evidence suggest the importance of different environments in promoting the pathogenesis and/or exacerbation of asthma. Indoor air pollution is a major contributor to human exposure, since people spend up to 90% of their day indoors. Apart from active smoking, indoor pollution is considered one of the major preventable risk factors of chronic respiratory diseases. The professional activity can also be dangerous because it exposes the subject to environments that can promote the onset of asthma or worsening of the latter in those already affected. Even bad habits such as incorrect diet, lead to more difficulty in controlling their disease. However asthma is a multifactorial disease in nature so it is not easy to distinguish the role of occupational exposure, pollution and normal habits such as smoking, nutrition, sports, etc. This retrospective study was conducted on a sample of asthma patients residing in the metropolitan area of Parma. 116 patients were selected among those who are followed up at least two years at the Asthma outpatient Clinic of Parma University Hospital. The sample in question is therefore closely controlled and monitored; it comes to patients who are well educated on the control of their disease, are able to take appropriate measures to minimize the symptomatology. With this tight approach is proposed to minimize the effect of confounding and then traced with greater certainty the possible cause of the failure to control the disease. For this purpose, each patient was subjected to regular checkups; we took as a reference the period of time between April and October 2015. During each visit, in addition to general data for each patient, we were collected personal information about their habits and way of life through a validated questionnaire delivered and completed by the patient during the visit in the presence of the permanent staff. The questionnaire covers mainly the qualification of the patient, its possible occupational exposure, his home, with information about nearby traffic, time spent outside, physical activity (place and time), exposure to chemicals, exposure to various fumes (fireplace or stove) and cigarette smoke, comorbidities and any drugs taken during the visits considered. Regarding the respiratory conditions of patients during every examination we were considered: Asthma Control Test (a test performed by patients to assess the state of the disease during the month preceding the test), the measurement of exhaled nitric oxide (FeNO) as an index of airways inflammation, measuring the resistance level of small airways (R5-R20) and some spirometric values observed in experiment; in particular the forced vital capacity (FVC), forced expiratory volume in the first second (FEV 1), FEV1/FVC ratio, forced expiratory flow rate over the middle 50% of the FVC (FEF25–75) and FEF25-75/FVC were recorded. The sample has been studied considering both the changes of the respiratory parameters for every patient in their examinations, and the respiratory parameters of all the examinations took as a whole in relation with the variables considered. From the results obtained, the patients are clinically stable; their adopted lifestyle and the exposure to possible sources of outdoor pollution, seems not affect the overall control of their disease. Some findings of our study are of interest. First, the subjects who carry a steroid therapy show a clinical worst, as revealed by the decrease of most spirometric indices, particularly FEF25, FEF75, FEF25-75 and R5-R20; also, the presence of comorbidities and the subsequent intake of other drugs, in addition to normal therapy for asthma, seem to be conditions associated with poorer performance in the functional respiratory parameters in particular FEV1/FVC, FEF75 and FEF25-75. Spirometric indexes that are down are mainly those related to obstruction imposed on small airways; this suggests a neglect to the latter on the contrary should be further explored and treated accordingly. It is also observed that both patients are overweight than those living on the lower floors and/or who have the most windows exposed to traffic, showed a decrease of pulmonary function, especially those relate to an obstruction at the small airways level. In conclusion, our results provided the evidence that a most appropriate therapy, specific to reach the small airways, associated with a healthy lifestyle, can help improve the management of asthma.

Challenging From Within : Youth Associations and Female Leadership in Swedish Mosques

This chapter focuses on women members of the Sunnī-dominated national organization Sweden's Young Muslims (Sveriges Unga Muslimer, SUM) and some of its local youth associations in different Swedish towns, to argue that involvement with these associations is increasing Muslim women's engagement with mosques and other venues for acquisition of Islamic knowledge. Illuminating the continuous challenges to the women's presence in mosques and their wider public activism the chapter examines how these women defend their right to exercise religious authority while supporting the traditional sources of Muslim authority in the public sphere. It analyzes how the women reinterpret the Islamic texts to change their daily lives as well as their position within both the Muslim community and Swedish society as a whole. The chapter emphasizes that in more informal situations, backstage among peers, the women put gender on the agenda, initiate reflexive deliberations, and test alternative norms and practices.

A new role for Low German? Language insertion as bilingual practice in the process of language shift

This article analyses language insertion as a bilingual communicative practice, applying a functional, speaker-focused approach to the study of sociolinguistics and language contact. The article is based on a study of contact phenomena in a formerly diglossic region in Northern Germany, where the previously spoken language – Low German – is in the process of being replaced by the dominant standard variety, German. It examines regional publications in order to establish the linguistic techniques by which Low German elements are incorporated into the Standard German texts and the communicative purposes that they serve. The paper concludes that in the process of language shift an emblematic repertoire from Low German is created which can be applied into the dominant contact language, German, for specific communicative purposes.

Novel peptide antagonists of adrenomedullin and calcitonin gene-related peptide receptors:identification, pharmacological characterization, and interactions with position 74 in receptor activity-modifying protein 1/3

Human adrenomedullin (AM) is a 52-amino acid peptide belonging to the calcitonin peptide family, which also includes calcitonin gene-related peptide (CGRP) and AM2. The two AM receptors, AM(1) and AM(2), are calcitonin receptor-like receptor (CL)/receptor activity-modifying protein (RAMP) (RAMP2 and RAMP3, respectively) heterodimers. CGRP receptors comprise CL/RAMP1. The only human AM receptor antagonist (AM(22-52)) is a truncated form of AM; it has low affinity and is only weakly selective for AM(1) over AM(2) receptors. To develop novel AM receptor antagonists, we explored the importance of different regions of AM in interactions with AM(1), AM(2), and CGRP receptors. AM(22-52) was the framework for generating further AM fragments (AM(26-52) and AM(30-52)), novel AM/alphaCGRP chimeras (C1-C5 and C9), and AM/AM(2) chimeras (C6-C8). cAMP assays were used to screen the antagonists at all receptors to determine their affinity and selectivity. Circular dichroism spectroscopy was used to investigate the secondary structures of AM and its related peptides. The data indicate that the structures of AM, AM2, and alphaCGRP differ from one another. Our chimeric approach enabled the identification of two nonselective high-affinity antagonists of AM(1), AM(2), and CGRP receptors (C2 and C6), one high-affinity antagonist of AM(2) receptors (C7), and a weak antagonist selective for the CGRP receptor (C5). By use of receptor mutagenesis, we also determined that the C-terminal nine amino acids of AM seem to be responsible for its interaction with Glu74 of RAMP3. We provide new information on the structure-activity relationship of AM, alphaCGRP, and AM2 and how AM interacts with CGRP and AM(2) receptors.

Jiddisch - niederdeutsche Sprachbeziehungen in Ostfriesland:Low German language relations in East Frisia

Recently discovered sources indicate that the Jewish population of East Frisia in Northwest Germany used a variety based on Western Yiddish as an in-group vernacular well into the 20th century. The East Frisian Jewish variety shows contact-induced traces of Low German, mainly in the lexicon but also in a number of morphological structures. This study does not only analyzes the influence of Low German on the East Frisian Jewish variety but also asks the question, whether three hundred years of language contact have led to traces of the Jewish variety in east Frisian Low German.

Linear binocular combination of responses to contrast modulation:contrast-weighted summation in first- and second-order vision

Binocular combination for first-order (luminancedefined) stimuli has been widely studied, but we know rather little about this binocular process for spatial modulations of contrast (second-order stimuli). We used phase-matching and amplitude-matching tasks to assess binocular combination of second-order phase and modulation depth simultaneously. With fixed modulation in one eye, we found that binocularly perceived phase was shifted, and perceived amplitude increased almost linearly as modulation depth in the other eye increased. At larger disparities, the phase shift was larger and the amplitude change was smaller. The degree of interocular correlation of the carriers had no influence. These results can be explained by an initial extraction of the contrast envelopes before binocular combination (consistent with the lack of dependence on carrier correlation) followed by a weighted linear summation of second-order modulations in which the weights (gains) for each eye are driven by the first-order carrier contrasts as previously found for first-order binocular combination. Perceived modulation depth fell markedly with increasing phase disparity unlike previous findings that perceived first-order contrast was almost independent of phase disparity. We present a simple revision to a widely used interocular gain-control theory that unifies first- and second-order binocular summation with a single principle-contrast-weighted summation-and we further elaborate the model for first-order combination. Conclusion: Second-order combination is controlled by first-order contrast.

Analysis of Mn-deposits in swedish lakes

In connection with a discovery of oxidic manganiferous and ferriferous precipitations in northern Vermland and north-western Dalecarlia, pH measurements of different waters and chemical analyses of waters and bog ores were carried out. The origin of the different bog ores is dealt with in connection with a discussion of some problems of the geochemistry of manganese and iron.

Particle flux at mooring sites in the Pacific Ocean (Table 1)

In order to understand the vertical transport of particulate matter, suspended and settling particles were collected along a meridional transect between 46°N and 35°S and an equatorial longitudinal transect between 135°E and 175°E in the Pacific. The low COrganic/N atomic ratios (<8.2) of suspended particulate organic matter (OM) and good correlation between particulate organic carbon (OC) and chlorophyll-a confirmed that the suspended particulate OM in the surface water was mainly produced by phytoplankton. Only 0.1-3.2% of primary production was transported to 1.3 km water depth in the boreal central Pacific. All data on settling particles (excluding deep trap data) showed strongly positive correlation between total mass and OM fluxes with high correlation factor of 0.93. Biogenic opal-producing plankton, mainly diatoms were responsible for most of the vertical transport of particulate OM in association with higher COrganic/CCarbonate ratios in the subarctic and equatorial hemipelagic regions in the Pacific. This vertical transport of settling particles potentially works as a sink of CO2. In the transition zone during the May 1993, large difference between PCO2 (<300 µatm) in the surface water and pCO2 (340 µatm) in the atmosphere was actually due to enhanced particulate OM flux. Since the deep water of the Pacific is enriched in CO2 and nutrients, upwelled seawater may tend to release CO2 to the atmosphere. However, higher production of particulate matter could reduce the partial pressure of CO2 in the surface water. Also terrestrial nutrients' inputs in the western equatorial Pacific have potential for the reduction of CO2 in the surface water.

Investigating relative clauses in children with specific language impairment

Background: It is well documented that children with Specific Language Impairment (SLI) experience significant grammatical deficits. While much of the focus in the past has been on their morphosyntactic difficulties, less is known about their acquisition of complex syntactic structures such as relative clauses. The role of memory in language performance has also become increasingly prominent in the literature. Aims: This study aims to investigate the control of an important complex syntactic structure, the relative clause, by school age children with SLI in Ireland, using a newly devised sentence recall task. It also aims to explore the role of verbal and short-termworking memory in the performance of children with SLI on the sentence recall task, using a standardized battery of tests based on Baddeley’s model of working memory. Methods and Procedures: Thirty two children with SLI, thirty two age matched typically developing children (AM-TD) between the ages of 6 and 7,11 years and twenty younger typically developing (YTD) children between 4,7 and 5 years, completed the task. The sentence recall (SR) task included 52 complex sentences and 17 fillers. It included relative clauses that are used in natural discourse and that reflect a developmental hierarchy. The relative clauses were also controlled for length and varied in syntactic complexity, representing the full range of syntactic roles. There were seven different relative clause types attached to either the predicate nominal of a copular clause (Pn), or to the direct object of a transitive clause (Do). Responses were recorded, transcribed and entered into a database for analysis. TheWorkingMemory Test Battery for children (WMTB-C—Pickering & Gathercole, 2001) was administered in order to explore the role of short-term memory and working memory on the children’s performance on the SR task. Outcomes and Results: The children with SLI showed significantly greater difficulty than the AM-TD group and the YTD group. With the exception of the genitive subject clauses, the children with SLI scored significantly higher on all sentences containing a Pn main clause than those containing a transitive main clause. Analysis of error types revealed the frequent production of a different type of relative clause than that presented in the task—with a strong word order preference in the NVN direction indicated for the children with SLI. The SR performance for the children with SLI was most highly correlated with expressive language skills and digit recall. Conclusions and Implications: Children with SLI have significantly greater difficulty with relative clauses than YTD children who are on average two years younger—relative clauses are a delay within a delay. Unlike the YTD children they show a tendency to simplify relative clauses in the noun verb noun (NVN) direction. They show a developmental hierarchy in their production of relative clause constructions and are highly influenced by the frequency distribution of the relative clauses in the ambient language.
