Enhancement of the thermal stability and mechanical properties of recycled low density polyethylene/wheat biocomposite films with targeted repairing technology and network skeleton construction
Authors: Xiao Dingtian , Qing Shan , Yu Zhifeng , Xiao Huaqiang 
Published: May 2019

In this paper, biocomposite films were prepared by using recycled low density polyethylene from marine plastic waste and wheat straw micropowders from common agricultural wastes in northern China. In order to determine the optimal ratio, eight experimental groups were set up for comparative testing. For further improving the performance of the biocomposite film, the three-dimensional network skeleton construction and targeted repairing technology of the material were designed. The specimens were characterized by a HD camera, a universal examination machine, a research grade inverted microscope, and a thermogravimetric analyzer. The results indicate that the agglomeration of powders reduces the tensile strength of the material, and the elongation at break depends on the properties of the polyolefin matrix itself. The reinforced biocomposite film has a 13.7 MPa tensile strength and a 243% elongation at break. It has slightly better mechanical properties than ordinary materials, which can be used as an economical, thermally stable, and environmentally friendly material to manufacture new packaging and courier bags.

Published: May 2019

BackgroundCertain personality traits may mediate the relationship between familiality and adversity in causing depression.AimsTo examine whether the neuroticism and extraversion scales ofthe Eysenck Personality Inventory (EPI) represent enduring traits underlying the vulnerability to respond to adversity by developing depressive episodes.MethodA total of 108 subjects with depression and their siblings were compared with 105 healthy control subjects and their siblings. All were interviewed using the Schedules for the Clinical Assessment of Neuropsychiatry and the Life Events and Difficulties Schedule. Subjects also completed the EPI.ResultsBoth neuroticism and extraversion were familial and correlated with mood and life event measures. There were no differences on either measure between the never-depressed siblings of probands with depression and controls. Regression analyses showed that the major influence on neuroticism was current mood.ConclusionsNeither extraversion nor neuroticism measures trait vulnerability to depression, and neuroticism scores mainly reflect symptoms of depression.

Published: May 2019

BackgroundSpontaneous dyskinesia and parkinsonism have been reported in never-medicated patients with schizophrenia but there has been no previous study of the natural history of these conditions.AimsTo determine the prevalence of spontaneous dyskinesia and parkinsonism in a group of never-medicated, chronically ill patients with schizophrenia on two occasions separated by an 18-month interval.MethodDyskinesia was assessed by the Abnormal Involuntary Movements Scale using Schooler and Kane criteria for its presence; parkinsonism by the Simpson and Angus scale; and mental state by the Positive and Negative Syndrome Scale for schizophrenia.ResultsThirty-seven patients were examined on two occasions. Nine (24%) had dyskinesia on both occasions, 12 (33%) on one occasion and 16 (43%) on neither occasion. Twenty-one (57%) had dyskinesia on at least one occasion. Thirteen patients (35%) had parkinsonism on at least one occasion.ConclusionsSpontaneous dyskinesia and parkinsonism fluctuate over time. The former was found on at least one occasion in the majority of patients. It is an integral part ofthe schizophrenic disease process.

BackgroundMagnetic resonance imaging (MRI) has demonstrated abnormalities of brain structure, particularly of the temporal lobes, in schizophrenia. These are thought to be neurodevelopmental in origin, but when they become evident is unknown.AimsTo determine iftemporal lobe volumes reduce during the development of symptoms of schizophrenia in initially well people at high riskofthis disorder.MethodA group of 66 people who had at least two first— or second-degree relatives with schizophrenia and a control group of 20 healthy people had a structural MRI scan ofthe whole brain which was repeated after approximately 2 years. Regions of interest, specifically the amygdala-hippocampus complex and the temporal lobes, were traced semi-automatically by three masked raters with good inter— and intrarater reliabilityResultsRegional brain volume changes over 2 years did notdiffer between high-risk and healthy participants. Within the high-risk group, the 19 people with psychotic symptoms (12 at first assessment) had a mean reduction of 2163 mm3 intherighttemporal lobe compared with 97 mm3 in the 47 without symptoms (P⩵0.02).ConclusionsOur findings suggest that people at high risk of schizophrenia with psychotic symptoms show reductions in temporal lobe volumes.

Published: May 2019

AbstractContextThe incidence of type 1 diabetes (T1D) is increasing worldwide. The quest to understand T1D etiology and how to predict diabetes is ongoing; and, in many ways, those goals intertwine. Although genetic components associate with T1D, not all individuals with T1D have those components, and T1D does not develop in all subjects with those components.ObjectiveMore robust methods for prediction of T1D are needed. We investigated if high CD4+CD40+ T-cell (Th40) levels can be used as a biomarker.MethodsTh40 levels were assessed along with other parameters in blood collected from prediabetic subjects in TrialNet.ResultsIn prediabetic subjects stratified according to Th40 cell level, patterns paralleled those seen between control subjects and those with T1D. Cytokine patterns were significantly different between those with high Th-40 levels (Th40-high) and those with low levels, and a CD4/CD8 double-positive population was more represented in Th40-high groups. Subjects experiencing impaired glucose tolerance had a significantly higher Th40 level than did control subjects. HLA DR4/DR4 and DQ8/DQ8 were more likely found among Th40-high subjects. Interestingly, HLA DR4/DR4 subjects were significantly older compared with all other subjects, suggesting that this haplotype, together with a high Th40 level, may represent someone in whom T1D will develop after age 30 years, which is reported for 42% of T1D cases.ConclusionConsidering the differences found in relation to prediabetic Th40 cell level, it may be possible to devise methods that more accurately predict who will proceed toward diabetes and, possibly, indicate prediabetic stage.
Mais Viva!
Authors: Santana Dora Silva 
Published: May 2019

Abstract
The author focuses on the concept of mais viva, a term in Brazilian Portuguese that can be roughly translated as “more alive, alert, savvy.” She theorizes the concept of mais viva as an embodied knowledge of black and trans resistance, a kind of critical awareness necessary for building self-love and building communities, along the lines of bell hooks's work. This discussion is an outcome of the dialogic theorizing that took place in the author's conversations with black Brazilian travesti activist Selen Ravache and her engagements with the work of Brazilian black feminist Beatriz Nascimento. The author argues that Selen's story is an instantiation of trans feminist work that taps on the Afro-diasporic legacy of fugitivity as refusal to lose oneself, even when one's self constitutes transformation, movement. She connects that discussion of fugitivity in the Brazilian African diaspora with the debates on trans and black fugitive principles in the United States indexed in the work of Tourmaline, Miss Major, C. Riley Snorton, Saidiya Hartman, and James Ford III, to name a few. Foregrounding black trans experiences from the southern hemisphere in relationship to transnational debates on gender, race, class, sexuality, disability, and nationality, among others, as part of a contingent conglomeration of elements, using Susan Stryker, Paisley Currah, and Lisa Jean Moore's terms, an assemblage constitutes one of the possibilities to rearrange, reassemble the ways we understand, move within, and intersect black, trans, and feminist studies.
Use of the surgical safety checklist in the operating room: Operating room nurses’ perspectives
Authors: Kisacik Oznur Gurlek , Cigerci Yeliz 
Published: May 2019

Objective: To determine the opinions of operating room nurses towards the Surgical Safety ChecklistTR (SSCTR) and to determine applications for using SSCTR in operating rooms.
Methods: This descriptive and cross-sectional study was conducted with 102 nurses working in the operating rooms of a state hospital and a university hospital in the Afyonkarahisar province. Descriptive statistics method were used for data analysis.
Results: It was found that all operating room nurses knew the SSCTR and that they had a positive opinion regarding the necessity of the SSCTR. However, most of the participants stated that the SSCTR was not applied effectively in the operating room.
Conclusion: The results obtained from the study show that changes focusing on the development of a culture of patient safety (PS) and team collaboration in operating rooms must be made in order to apply SSCTR consistently and properly.

Attitudes and perceptions of paramedics about end-of-life care: a literature review
Authors: Pentaris Panagiotis , Mehmet Nevin 
Published: May 2019

Background: Paramedics must be prepared to respond to crises in which a threat to a patient's health may result in death. They are therefore highly involved with end-of-life care. Aims: Involvement with end-of-life care is the context in which this paper examines how paramedics perceive and respond to this part of their role. Methods: This is a systematic literature review that examines current evidence. Findings: Five themes emerged, which suggest that paramedics are not prepared to work with crisis situations involving the end of patients' lives: emotional resilience; decision making; communicating death; recognising dying patients; and death education. Conclusion: The current review concludes that the dearth of data is not preventing improvements in services, nor education and training, in this field.
Sobre la crítica de la presentación noemática de la alteridaden M. Henryy el despliegue de una fenomenología de lo inaparente
Authors: Inverso Hernán 
Published: May 2019

En vistas de una revisión general de la noción de sujeto, Michel Henry objeta, por un lado, su asociación con la representación y, por otro, el tratamiento de la alteridad presentada de manera intencional. Apunta con ello a mostrar en qué sentido la intencionalidad y la constitución no son las vías fenomenológicas adecuadas para dar cuenta del a priori universal de la experiencia de la alteridad. En rigor, la posición henryana sobre la crítica del sujeto no sólo pone en cuestión las presentaciones noemáticas de la alteridad, sino que se extiende hacia todo intento de dar cuenta del Otro desde una perspectiva que no sea auto-afectiva. Sin embargo, lo que a primera parece irreconciliable con el horizonte fenomenológico husserliano, puede resultar un aporte sustantivo en este mismo terreno. Examinaremos aquí la crítica a la postura husserliana para establecer una clave de lectura que no provoque una colisión entre ellas sino una sinergia que, retomando la potencia de los orígenes, despliegue un programa de investigación que abarque el estudio de todo el arco de la fenomenicidad.
Effect of moderate and high-intensity endurance and resistance training on serum concentrations of MSTN and IGF-1 in old male Wistar rats
Authors: Shanazari Zohreh , Faramarzi Mohammad , Banitalebi Ebrahim , Hemmati Roohullah 
Published: May 2019

Abstract

Background
Skeletal muscle is very sensitive to extracellular and intracellular signaling evoked by contractions from endurance and resistance exercise. The aim of this study was to compare the effects of moderate- and high-intensity endurance and resistance training on the serum myostatin (MSTN) and insulin-like growth factor (IGF-1) levels in older rats.

Materials and methods
Fifty old Wistar male rats (23 months old) were randomly divided into four experimental and one control groups, including moderate-endurance training (MET) (n = 10), high-intensity endurance training (EHT) (n = 10), moderate-intensity resistance training (MRT) (n = 10), high-intensity resistance training (HRT) (n = 10), and control group (C) (n = 10). Seventy-two hours after the last exercise session, euthanasia of the rats were rendered unconscious and direct blood samples were collected. Serum IGF-1 and MSTN concentration were measured using the enzyme-linked immuno sorbent assay (ELISA) method. The statistical analysis was performed using one-way analysis of variance (ANOVA) test with a significance level of p ≤ 0.05.

Results
There was a significant reduction in MSTN and an increase in IGF-1 concentrations was observed between IGF-I levels in high and moderate resistance and endurance training. However, no significant difference was observed in MSTN levels between groups.

Discussion
Therefore, it appears that resistance training, especially HRT, is effective to increase growth mediators among older rats.
On the Haagerup and Kazhdan properties of R. Thompson’s groups
Authors: Brothier Arnaud , Jones Vaughan F. R. 
Published: May 2019

Abstract
A machinery developed by the second author produces a rich family of unitary representations of the Thompson groups F, T and V.
We use it to give direct proofs of two previously known results.
First, we exhibit a unitary representation of V that has an almost invariant vector but no nonzero

-invariant vectors reproving and extending Reznikoff’s result that any intermediate subgroup between the commutator subgroup of F and V does not have Kazhdan’s property (T) (though Reznikoff proved it for subgroups of T).
Second, we construct a one parameter family interpolating between the trivial and the left regular representations of V.
We exhibit a net of coefficients for those representations which vanish at infinity on T and converge to 1 thus reproving that T has the Haagerup property after Farley who further proved that V has this property.
Comparing M/G/1 queue estimators in Monte Carlo simulation through the tested generator “getRDS” and the proposed “getLHS” using variance reduction
Authors: Boubalou Meriem , Ourbih-Tari Megdouda , Aloui Abdelouhab , Zioui Arezki 
Published: May 2019

Abstract
In this paper, we propose a Latin hypercube sampling (LHS) number generator in C language under Linux called getLHS in order to compare both methods LHS and refined descriptive sampling (RDS) method.
It was highly tested by adequate statistical tests and compared statistically to the getRDS number generator.
We noticed that getRDS has passed all tests better than the proposed getLHS generator.
A simulation of M/G/1 queues is performed using getRDS to sample inputs from the RDS method and getLHS to sample inputs from the LHS method.
The results obtained through simulation demonstrate that the RDS method produces more accurate point estimates of the true parameters than the LHS method.
Moreover, the RDS method can significantly improve the performance of the studied queues compared to the well-known LHS method since its variance reduction factor is quite good in almost all cases.
It is then proved that RDS is an improvement over LHS at least on queues.
Two cases of spontaneous remission of primary hyperparathyroidism due to auto-infarction: different management and their outcomes

SummarySpontaneous remission of primary hyperparathyroidism (PHPT) due to necrosis and haemorrhage of parathyroid adenoma, the so-called ‘parathyroid auto-infarction’ is a very rare, but previously described phenomenon. Patients usually undergo parathyroidectomy or remain under close clinical and biochemical surveillance. We report two cases of parathyroid auto-infarction diagnosed in the same tertiary centre; one managed surgically and the other conservatively up to the present time. Case #1 was a 51-year old man with PHPT (adjusted (adj.) calcium: 3.11 mmol/L (reference range (RR): 2.20–2.60 mmol/L), parathyroid hormone (PTH) 26.9 pmol/L (RR: 1.6–6.9 pmol/L) and urine calcium excretion consistent with PHPT) referred for parathyroidectomy. Repeat biochemistry 4 weeks later at the surgical clinic showed normal adj. calcium (2.43 mmol/L) and reduced PTH. Serial ultrasound imaging demonstrated reduction in size of the parathyroid lesion from 33 to 17 mm. Twenty months later, following recurrence of hypercalcaemia, he underwent neck exploration and resection of an enlarged right inferior parathyroid gland. Histology revealed increased fibrosis and haemosiderin deposits in the parathyroid lesion in keeping with auto-infarction. Case #2 was a 54-year-old lady admitted with severe hypercalcaemia (adj. calcium: 4.58 mmol/L, PTH 51.6 pmol/L (RR: 1.6–6.9 pmol/L)) and severe vitamin D deficiency. She was treated with intravenous fluids and pamidronate and 8 days later developed symptomatic hypocalcaemia (1.88 mmol/L) with dramatic decrease of PTH (17.6 pmol/L). MRI of the neck showed a 44 mm large cystic parathyroid lesion. To date, (18 months later), she has remained normocalcaemic.Learning points:Primary hyperparathyroidism (PHPT) is characterised by excess parathyroid hormone (PTH) secretion arising mostly from one or more autonomously functioning parathyroid adenomas (up to 85%), diffuse parathyroid hyperplasia (<15%) and in 1–2% of cases from parathyroid carcinoma.PHPT and hypercalcaemia of malignancy, account for the majority of clinical presentations of hypercalcaemia.Spontaneous remission of PHPT due to necrosis, haemorrhage and infarction of parathyroid adenoma, the so-called ‘parathyroid auto-infarction’, ‘auto-parathyroidectomy’ or ‘parathyroid apoplexy’ is a very rare in clinical practice but has been previously reported in the literature.In most cases, patients with parathyroid auto-infarction undergo parathyroidectomy. Those who are managed conservatively need to remain under close clinical and biochemical surveillance long-term as in most cases PHPT recurs, sometimes several years after auto-infarction.
La communauté déplacée. Écriture et communauté dans le dialogue entre Maurice Blanchot et Jean-Luc Nancy.
Authors: Martínez Olguín Juan José 
Published: May 2019

Avec la publication de La communauté désœuvrée et La communauté inavouable, Maurice Blanchot et Jean-Luc Nancy commencent, au début des années 1980, un dialogue dont l’objet fut le thème de la communauté. Ce dialogue, cependant, n’impliquait pas seulement les noms de Blanchot et Nancy : ils se reconnaissaient héritiers d’une réflexion qui avait déjà commencé Nietzsche et Bataille. Plusieurs années plus tard, dans La communauté désavouée, Nancy revient sur ce débat et il s’y interroge : qu’est-ce que Blanchot voulait dire avec les arguments qu’il avait opposé contre le livre écrit par Nancy ? Partant de cette question, avec laquelle Nancy commence le dernier essai autour ce thème, ce travail propose de reconstruire le dialogue entre Blanchot et Nancy pour y trouver le lien entre communauté et écriture.
My Tattoos Caused My Dry Eye?
Authors: Morrison Caitlin J , Stamm Joseph M 
Published: May 2019

Purpose: This case report describes the potential impact of tattooed eyeliner on eyelid structure and function resulting in an increase in dry eye symptoms and findings.
Case Report: A 59-year-old Hispanic female presented for an evaluation following longstanding dry eye symptoms with little relief from artificial tears. Imaging showed meibomian gland dropout, possibly a result of her tattooed eyeliner. Symptoms and objective measurements improved successfully with warm compresses, lid massage, and lipid-based artificial tears.
Conclusions. Permanent tattooed eyeliner may enhance dryness of the eyes in two main ways: disruption of the architecture of the lids and chronic inflammation from tattoo pigment granules. Recognizing these possible effects in patients with tattooed eyeliner may help tailor treatment to be specific to the etiology of the patient’s dry eye: aiding the remaining meibomian glands by utilizing warm compresses, lid massage and supplementing the lipid from the missing meibomian glands by employing lipid-based artificial tears.
The seniors boom and economic repercussions: Waterloo Region economic development opportunities for growth in an aging society
Authors: Suerich Tracy 
Published: May 2019

<p>The population in Canada is aging, and even the ‘Silicon Valley of the North’ Waterloo Region is no exception. Aging societies can have a positive impact on the Economy; however, proper policies and programs must be in place in order to thrive through the peak of the Baby Boom retirement wave in 2026. This paper discusses research and recommendations from literature reviews and best practices found among municipalities regarding methods to thrive in an aging society. It is hoped that this paper will aid economic developers and supporting organizations to prepare for the impending age shift through adapting new employment, service, and built environment policies and programs. Adapting economic development now may prevent future economic downturns due to changes in work, lifestyle, and spending habits that are expected throughout the aging and retirement of the baby boom generation. </p><p><strong>Keywords: </strong>Older adults, senior, caregiver, age friendly, anti-aging, adaptive employment</p>
