Coordination chemistry of polyoxo-carbocyclic compounds containing one or more neighboring oxo-groups
Authors: Kovalchukova Olga , Strashnova Svetlana 
Published: November 2013

AbstractThis is a review of publications concerning the results of X-ray analysis of single crystals and spectrochemical characteristics of metal complexes containing polyoxo-carbocyclic compounds with one or more neighboring oxo-groups. The features of lattice characteristics and coordination modes, depending on the nature of the organic dianion, are shown here. The squarate anions, ${{\rm{C}}_{\rm{4}}}{\rm{O}}_{\rm{4}}^{{\rm{2 - }}}$ are predominantly involved in monodentate bridging coordination, and the derivatives containing five or six C-atoms in the cycle (croconate and rhodizonate anions) usually form bidentate chelating bridged modes. The stabilization of the crystal lattices of the metal complexes is due to the formation of hydrogen bonds and π-π stackings, which produce self-assembled three-dimensional (3D) structures with cavities and intercalation of some small molecules. The strong interlayer interactions lead to appearance of specific conductometric and magnetic properties, which together with their high thermal stabilities, make the oxocarbon complexes new and perspective materials for electronics and related areas.

OBJECTIVE:Sudden and unexplained death is a leading cause of infant mortality. Certain characteristics of the sleep environment increase the risk for sleep-related sudden and unexplained infant death. These characteristics have the potential to generate asphyxial conditions. We tested the hypothesis that infants may be exposed to differing degrees of asphyxia in sleep environments, such that vulnerable infants with a severe underlying brainstem deficiency in serotonergic, γ-aminobutyric acid-ergic, or 14-3-3 transduction proteins succumb even without asphyxial triggers (eg, supine), whereas infants with intermediate or borderline brainstem deficiencies require asphyxial stressors to precipitate death.METHODS:We classified cases of sudden infant death into categories relative to a “potential asphyxia” schema in a cohort autopsied at the San Diego County Medical Examiner’s Office. Controls were infants who died with known causes of death established at autopsy. Analysis of covariance tested for differences between groups.RESULTS:Medullary neurochemical abnormalities were present in both infants dying suddenly in circumstances consistent with asphyxia and infants dying suddenly without obvious asphyxia-generating circumstances. There were no differences in the mean neurochemical measures between these 2 groups, although mean measures were both significantly lower (P &lt; .05) than those of controls dying of known causes.CONCLUSIONS:We found no direct relationship between the presence of potentially asphyxia conditions in the sleep environment and brainstem abnormalities in infants dying suddenly and unexpectedly. Brainstem abnormalities were associated with both asphyxia-generating and non–asphyxia generating conditions. Heeding safe sleep messages is essential for all infants, especially given our current inability to detect underlying vulnerabilities.

OBJECTIVES:
To establish longitudinal validation of a new tool, the Asthma Symptom Tracker (AST). AST combines weekly use of the Asthma Control Test with a color-coded graph for visual trending.

METHODS:
Prospective cohort study of children age 2 to 18 years admitted for asthma. Parents or children (n = 210) completed baseline AST assessments during hospitalization, then over 6 months after discharge. Concurrent with the first 5 AST assessments, the Asthma Control Questionnaire (ACQ) was administered for comparison.

RESULTS:
Test–retest reliability (intraclass correlation) was moderate, with a small longitudinal variation of AST measurements within subjects during follow-ups. Internal consistency was strong at baseline (Cronbach’s α 0.70) and during follow-ups (Cronbach’s α 0.82–0.90). Criterion validity demonstrated a significant correlation between AST and ACQ scores at baseline (r = −0.80, P &lt; .01) and during follow-ups (r = −0.64, −0.72, −0.63, and −0.69). The AST was responsive to change over time; an increased ACQ score by 1 point was associated with a decreased AST score by 2.65 points (P &lt; .01) at baseline and 3.11 points (P &lt; .01) during follow-ups. Discriminant validity demonstrated a strong association between decreased AST scores and increased oral corticosteroid use (odds ratio 1.13, 95% confidence interval, 1.10–1.16, P &lt; .01) and increased unscheduled acute asthma visits (odds ratio 1.23, 95% confidence interval, 1.18–1.28, P &lt; .01).

CONCLUSIONS:
The AST is reliable, valid, and responsive to change over time, and can facilitate ongoing monitoring of asthma control and proactive medical decision-making in children.

Published: November 2013

OBJECTIVES:
To determine if a standardized global child health (GCH) modular course for pediatric residents leads to satisfaction, learning, and behavior change.

METHODS:
Four 1-hour interactive GCH modules were developed addressing priority GCH topics. “Site champions” from 4 Canadian institutions delivered modules to pediatric residents from their respective programs during academic half-days. A pre–post, mixed methods evaluation incorporated satisfaction surveys, multiple-choice knowledge tests, and focus group discussions involving residents and satisfaction surveys from program directors.

RESULTS:
A total of 125 trainees participated in ≥1 module. Satisfaction levels were high. Focus group participants reported high satisfaction with the concepts taught and the dynamic, participatory approach used, which incorporated multimedia resources. Mean scores on knowledge tests increased significantly postintervention for 3 of the 4 modules (P &lt; .001), and residents cited increases in their practical knowledge, global health awareness, and motivation to learn about global health. Program directors unanimously agreed that the modules were relevant, interesting, and could be integrated within existing formal training time.

CONCLUSIONS:
A relatively short, participatory, foundational GCH modular curriculum facilitated knowledge acquisition and attitude change. It could be scaled up and serve as a model for other standardized North American curricula.
Cough and Cold Medication Adverse Events After Market Withdrawal and Labeling Revision
Authors: Hampton Lee M. , Nguyen Duc B. , Edwards Jonathan R. , Budnitz Daniel S. 
Published: November 2013

BACKGROUND:
In October 2007, manufacturers voluntarily withdrew over-the-counter (OTC) infant cough and cold medications (CCMs) from the US market. A year later, manufacturers announced OTC CCM labeling would be revised to warn against OTC CCM use by children aged &lt;4 years. We determined whether emergency department (ED) visits for CCM adverse drug events (ADEs) declined after these interventions.

METHODS:
We used National Electronic Injury Surveillance System-Cooperative Adverse Drug Event Surveillance data from 2004 to 2011 to estimate the number of ED visits for CCM ADEs before and after each intervention.

RESULTS:
Among children aged &lt;2 years, ED visits for CCM ADEs decreased from 4.1% of all ADE ED visits before the market withdrawal to 2.4% of all ADE visits afterward (difference in proportion: –1.7%, 95% confidence interval [CI]: –2.7% to –0.6%). Among children aged 2 to 3 years, ED visits for CCM ADEs decreased from 9.5% of all ADE ED visits before the labeling revision announcement to 6.5% of all ADE visits afterward (difference in proportion: –3.0%, 95% CI: –5.4% to –0.6%). Unsupervised ingestions accounted for 64.3% (95% CI: 51.1% to 77.5%) of CCM ADE ED visits involving children aged &lt;2 years after the withdrawal and 88.8% (95% CI: 83.8% to 93.8%) of visits involving children aged 2 to 3 years after the labeling revision announcement.

CONCLUSIONS:
After a voluntary market withdrawal and labeling revision, ED visits for CCM ADEs declined among children aged &lt;2 years and 2 to 3 years relative to ADE ED visits for all drugs. Interventions addressing unsupervised ingestions are needed to reduce CCM ADEs.

Resistance Conditions and Applications
Authors: Kinnunen Juha , Silvestre Pilar 
Published: November 2013

Abstract
This paper studies analytic aspects of so-called resistance
conditions on metric measure spaces with a doubling measure.
These conditions are weaker than the usually assumed
Poincaré inequality, but however, they are sufficiently strong
to imply several useful results in analysis on metric measure
spaces. We show that under a perimeter resistance condition,
the capacity of order one and the Hausdorff content of
codimension one are comparable. Moreover, we have connections
to the Sobolev inequality for compactly supported
Lipschitz functions on balls as well as capacitary strong type
estimates for the Hardy-Littlewood maximal function. We also
consider extensions to Sobolev type inequalities with two different
measures and Lorentz type estimates.

Abstract
In this paper we prove that every collection of measurable
functions fα , |α| = m, coincides a.e. withmth order derivatives
of a function g ∈ Cm−1 whose derivatives of order m − 1 may
have any modulus of continuity weaker than that of a Lipschitz
function. This is a stronger version of earlier results of Lusin,
Moonens-Pfeffer and Francos. As an application we construct
surfaces in the Heisenberg group with tangent spaces being

Abstract
The study considers ship’s rolling amplitude as one of the key parameters influencing liquid sloshing in partly filled tanks during sea voyage. This issue is strictly related to the safety of navigation matters and belongs to the group of non-linear hydrodynamic phenomena. The presented investigation is focused on the estimation of typical and extreme rolling amplitude of a vessel in terms of dynamic approach towards liquid motion onboard ships. The number of exemplary numerical simulations of liquid sloshing taking place in moving tanks is carried out and the heeling moment due to liquid sloshing is obtained.

Published: November 2013

Abstract
Background: Although it is generally accepted that there is an increased oxidative stress status in alcoholics, the separate relevance of oxidative stress following alcohol withdrawal is still not understood to this date. There are reports stating that the increased oxidative stress status in alcoholics may persist independently of the constant presence of alcohol intake, while on the other side, it was demonstrated that the antioxidant defense mechanism could significantly increase after alcohol withdrawal.
Methods: In the present work, we were interested in studying the relevance of oxidative stress status in the alcohol withdrawal processes, by determining some oxidative stress markers (two antioxidant enzymes: superoxide dismutase - SOD and glutathione peroxidase - GPX and a lipid peroxidation maker - MDA) after one week and one month of abstinence, as compared to the baseline and a control group of subjects.
Results: Our data confirmed the increased oxidative stress status in alcoholic patients and, more importantly, we de m - onstrated here a significant decrease of the oxidative stress status one week and one month following the withdrawal, as showed by a significant increase in the specific activity of SOD (p<0.003), as well as by a decrease in MDA levels (p<0.019). Still, in the case of all three markers of oxidative stress status which we determined, the levels after one week or one month of abstinence were significantly altered when compared to controls.
Conclusions: This suggests that severe and prolonged deficiency in the oxidative stress marker levels needs longer than one month of abstinence to normalize.
The Proposal of Key Performance Indicators in Facility Management and Determination the Weights of Significance
Authors: Rimbalová Jarmila , Vilčeková Silvia 
Published: November 2013

Abstract
The practice of facilities management is rapidly evolving with the increasing interest in the discourse of sustainable development. The industry and its market are forecasted to develop to include non-core functions, activities traditionally not associated with this profession, but which are increasingly being addressed by facilities managers. The scale of growth in the built environment and the consequential growth of the facility management sector is anticipated to be enormous. Key Performance Indicators (KPI) are measure that provides essential information about performance of facility services delivery. In selecting KPI, it is critical to limit them to those factors that are essential to the organization reaching its goals. It is also important to keep the number of KPI small just to keep everyone's attention focused on achieving the same KPIs. This paper deals with the determination of weights of KPI of FM in terms of the design and use of sustainable buildings.
Hawthorne’s Perspectival Perversity: What if “Wakefield” Were (About) a Woman?; or, Credo Quia Absurdum
Authors: Semrau Janusz 
Published: November 2013

Abstract
Although “Wakefield” opens as a leisurely mnemonic act, it turns into an intensely emotional affair. However, the stance of moral indignation and, indeed, condemnation adopted in many readings of this classic tale seems to be a monological trap, an interpretive ride along Einbahnstrasse. The present close re-reading draws on the combined appreciation of perversity as (i) formal figuration in which the bearings of the original are reversed, (ii) attitudinal disposition to proceed against the weight of evidence (the so-called ‘being stubborn in error’). Building on this logic, the paper offers a transcriptive anti-type response to Hawthorne’s title. It is meant as a detour of understanding and a reclamation of a seemingly obvious relational and denotative proposition. Inasmuch as “Wakefield” is a distinctive rhetorical performance, foundationally a story about story-telling, its title can be naturalized as identifying the story-teller. Even if this does not come across as lucius ordo, it is argued that the order of reappropriative and be-longing signification is that of Mrs. rather than - as is commonly believed - that of Mr. Wakefield. Informed by object permanence and a peculiar looking bias, “Wakefield” proves to be her-tale rather than his-story. As a secret sharer and a would be-speaking gaze, the wife turns out to be a structural and existential pivot of the narrative. More broadly, Mrs. Wakefield can be appreciated as coarticulator of a ventriloquistic logos and choreographer of a telescopic parallactic vision. Unintentional challenge to both the heresy of paraphrase and the aesthetics of astonishment, this is ultimately to proffer a radical Shakespearean/Kantian re-cognition that in certain spheres there obtains nothing absolutely ‘moral’ or ‘immoral’, and it is only a particular perspectival discourse that may make it so.
Neighborhood base at the identity of free paratopological groups

Published: November 2013

AbstractIn 1985, V. G. Pestov described a neighborhood base at the
identity of free topological groups on a Tychonoff space in
terms of the elements of the fine uniformity on the Tychonoff
space. In this paper, we extend Postev’s description to the
free paratopological groups where we introduce a neighborhood
base at the identity of free paratopological groups on any
topological space in terms of the elements of the fine quasiuniformity
on the space.

Abstract
A new distribution boundary of the dice snake, Natrix tessellate (Laurenti, 1768), in Ukraine has been established. The northern edge currently lies within the valley of the middle course of the Dnipro River: Trakhtemyriv Peninsula, Cherkasy Region on the right side (49°59′ N, 31°25′ E); on the left side in Kyiv Region within Pereyaslav-Khmelnytsky District: at a fishermen’s station (50°02' N, 31°17' E), yacht club (Kurinoye Estuary 50°02′ N, 31°29′ E); Lubny, Poltava Region (49°58 N, 33°01′ E). These points are located 70-80 km northwards from the previous boundary of the species home range. The level of Natrix tessellata population polymorphism in the North of Cherkasy Region is high; more than 40 % of specimens are dark-colored.
La fin de l'analyse et la formation du symbole

Published: November 2013

En s’appuyant sur deux textes fondamentaux, l’un de Freud, « L’analyse avec fin et l’analyse sans fin », l’autre de Jung, Psychologie du transfert , l’auteur explore ici l’effet de la formation du symbole au cours du processus de la fin de l’analyse. Cette formation d’un symbole donne le sens à l’arrêt de la relation analytique et à la poursuite de l’auto-analyse par la pratique de la fonction transcendante, ce travail conscient de la relation entre les forces conscientes et inconscientes.
A Rare Presentation of Euthyroid Orbitopathy in Papillary Thyroid Carcinoma
Authors: Vaidya Abhishek , Tamhankar Anup Sunil 
Published: November 2013

ABSTRACTOphthalmopathy is one of the known presenting features of Grave's disease. Its due to development of antithyroid receptor antib odies. Rarely it may b e asso ciated with th yroid malignancies developing in the Grave's nodule. There are few case reports of patients with coexisting thyroid associated orbitopathy (TAO) and thyroid carcinoma. Sometimes it may be the presenting symptom of an occult thyroid malignancy. Its still rarer if the patient is euthyroid on presentation. It is associated with low titers of antithyroid receptor antibodies. Here we present a very rare case of symmetrical nonmetastatic orbitopathy in a euthyroid papillary carcinoma of thyroid.Key messageIts important to rule out coexisting thyroid cancer in patient presenting with orbitopathy even if euthyroid. Orbitopathy may regress after thyroidectomy. Association of thyroid cancer, autoimmunity and orbitopathy is still to be proven due to lack of large case series.How to cite this articleChaturvedi P, Vaidya A, Tamhankar AS.

Published: November 2013

ABSTRACTMesenchymal chondrosarcoma is a rare aggressive neoplasm affecting the bones of young adults. It also arises extraskeletal in CNS, so ft tissu e and other o rgans. Intrac ran ial and those that originate from the dura mater are very rare. These tumors constitute an entirely different entity from classical chondrosarcoma. These are characterized by a bimorphic histological pattern composed of highly undifferentiated small round to oval cells and islands of well-differentiated hyaline cartilage with calcification and ossification. We hereby report a case of mesenchymal chondrosarcoma arising from the right tentorium cerebelli in a 40-year-old man with symptoms of mass effect. Histological examination demonstrated sheets of round to oval cells with islands of hyaline cartilage. The diagnosis of mesenchymal chondrosarcoma was made after a thorough microsco pic assessmen t. T umo r in add ition to cellular component also revealed a prominent cartilaginous component. We hereby discuss the morphological features of mesenchymal chondrosarcoma arising in the CNS, the differential diagnoses of small round-cell tumors within the CNS, and the differentiating features of mesenchymal chondrosarcoma from the other differential diagnoses.How to cite this articleTanvir I, Riaz S, Khan HA, Loya A, Shahid K.
