Authors: Mai Nguyen Sao , Tan Dao Van 
Published: April 2018

Sonneratia apetala pneumatophore samples were collected from Xuan Thuy National Park, and then 80% methanol extract was fractionated through Sephadex LH-20 column chromatography. After elution with 95% ethanol and 50% acetone, two phenolic fractions were obtained from the crude extract of of S. apetala pneumatophore. The acetone fraction consisted of tannins having high antioxidant activity, 1.14 times higher than that of ascorbic acid. This fraction also have higher activity of α-amylase inhibition (IC50 0.83 mg/mL) and R. sativus root growth inhibition (IC50 6.4 mg/mL) than did the ethanol fraction. In contrast, ethanol fraction consisted of low-molecular phenolic compounds having inhibitory effects on Samonella tiphimurium growth. Such antibacterial activity was not observed in the acetone extract. Citation: Nguyen Sao Mai, Dao Van Tan, 2017.

Published: April 2018

Tintinnidsarean important protozoan group in the aquatic food web and had been widely studied in various waters. There are about 1000 known species in the world. However, there have beenvery few taxonomic studies in Vietnam and therefore the number of Tintinnid taxa and their distribution are poorly known. Thepresent study documents 65 tintinnids species belonging to 30 genera and 13 families in samples collected from Khanh Hoa - Binh Thuan waters in 2016 and 2017. There were 17 new taxa records for Vietnam protozoan fauna, raising the number of tintinnids recorded in Vietnam to 125 taxa. Tintinnid assemblages in Khanh Hoa-Binh Thuan waters shared about 17 species with Ha Long Bay, 32 species with Con Co island and 26 species with coastal waters of South Vietnam. Analysis of species diversity shows that the Shannon diversity index H' varied from 1.5 to 2.6. Distribution of species numbers and diversity in the Khanh Hoa - Binh Thuan waters revealed possible combined effects of hydrographical activities (e.g. upwelling), Mekong river influent (e.g. salinity), and food available on tintinnid communities.

Published: April 2018

Background: Yoga is a traditional technique to conserve and purify body, mind and soul. It is a mind-body bridge which involves relaxation, meditation and a set of physical exercises performed in association with breathing. In this new era of evolution, most of the population are depressed or in stress, irrespective of their age and gender.Methods: This study is performed on 1st yr. medical students whose stress level is in higher side due to academic burden. An 55 medical students were selected as participants through counseling and were divided into yoga group (n= 27) and control group (n=28). Their morning serum cortisol level was assessed, and yoga group were instructed to practice yoga (1hr/day for 12 weeks) under supervision of yoga instructor. No such instruction was given to control group.Results: Serum cortisol level is the marker of stress and inflammation. Higher cortisol level means high stress level. Yoga and meditation is documented to reduce stress level in regular practitioners. Statistical analysis has shown decrease in morning serum cortisol level (572.18±168.03 to 544.98±139.89, 4.8% decrease, P value ˂0.05, significant) in yoga group after study. Control group have shown marked increase in cortisol level (558.89±162.69 to 577.26±254.5, 3.4% increase, P value = 0.74, not significant) after three months of study.Conclusions: This study concludes that practicing Yoga has a significant effect on the reduction of stress and anxiety level in medical students.
Early complications of ultrasound guided central vein catheterization in children
Authors: Arda Mehmet Surhan 
Published: April 2018

Background: Since mid-20th century Central Venous Catheter (CVC) has been in use. Cut-down was the initial approach that was followed by Seldinger method. Thereafter, anatomic land-mark has been recommended and finally it was switched to ultrasound (USG) guidance. In adults the lower complication and higher success rates of USG guided catheterization has been reported. However, in children, although it was accepted that USG guidance lowers puncture rates, increased success and decreased complication by USG was controversial. Methods: Between 01/07/2014 and 31/12/2017 records of patients that were younger than five years old and that were undergone USG guided CVC placing have been extracted. The early complications due to catheterization was evaluated.Results: A total 259 patients met our criteria. All of them have placed catheter successfully whereas mean puncture rate was 1.32. The 18.9% of them necessitated repetitive procedures of whom 44.9% (n= 22) of them have been catheterized from the previous central line. Thrombosis was detected in only 2.7% (n= 7) of them. Arterial puncture was noticed in four.Conclusions: USG guided central vein catheterization is safe and reliable with lower complication. It could be speculated that lower puncture rates might have great influence on patency of vessels.

Abstract
An acute gastroenteritis outbreak occurred at a private college in June 2014 in northwest China. This outbreak involved two teachers and 629 students (range: 17–27 years, average 21.3 years). The main symptoms included non-bloody watery diarrhea, stomach ache, nausea, and vomiting, and the duration of illness ranged from 1 to 7 days. Eight of 18 water samples were disqualified. Thirty-four norovirus (NoV) RNA-positive samples were identified from 48 stool-related samples (genotyping results: 13 GII, 13 GI and 8 GI + GII mixture). Fourteen NoV samples were successfully characterized for genotype, including two GII.6, five GI.6, four GI.3, and three GI.1. Enteropathogenic Escherichia coli (EPEC) and enteroadherent Escherichia coli (EAEC) DNA was detected from patient stool specimens and water samples from well one; two EAEC strains and one EPEC strain were isolated from patient stool specimens. The risk ratios (RRs) associated with wells one and two were 1.66 and 1.49, respectively, and the RR associated with living in north dormitory building one was 2.59. The patients' epidemiological characteristics, symptoms, and duration of illness indicated that NoV-contaminated water might be the origin of this outbreak, and RR analysis suggested that the two wells were linked to the outbreak.
Musculoskeletal Manifestations of Sarcoidosis: A Review Article
Authors: Shariatmaghani Somayeh , Salari Roshanak , Sahebari Maryam , Tabrizi Payman Shalchian , Salari Masoumeh 
Published: April 2018

Background:
Sarcoidosis is a multisystem inflammatory disease with an etiology that is
not clearly understood. Amongst the different organs that may be affected, the lungs are the most
common. Musculoskeletal manifestations of the disease are uncommon.

Objectives:
They include arthropathy, bone lesions, or myopathy, all of which may occur as initial
symptoms or develop during the course of the disease.

Methods:
: Articular involvement my present as arthralgia or arthritis. Skeletal complications usually
develop in the chronic state of the disease. Muscular disease is rare and usually asymptomatic. Appropriate
imaging modalities including X-ray, MRI, FDG-PET/CT assist in the diagnosis of rheumatic
sarcoidosis. However, biopsy is necessary for definite diagnosis.

Result and Conclusion:
In most cases of musculoskeletal involvement, NSAIDs and corticosteroids
are sufficient for symptomatic management. For more resistant cases immunosuppressive
drugs (i.e., methotrexate) and TNF- inhibitors are used. Our aim is to review various types of musculoskeletal
involvement in sarcoidosis and their existing treatment options.
Glioma and Neurokinin-1 Receptor Antagonists: A New Therapeutic Approach
Authors: Muñoz Miguel , Coveñas Rafael 
Published: April 2018

Background:In adults, the most lethal and frequent primary brain tumor is glioblastoma. Despite multimodal aggressive therapies, the median survival time after diagnosis is around 15 months. In part, this is due to the blood-brain barrier that restricts common treatments (e.g., chemotherapy). Unfortunately, glioma recurs in 90% of patients. New therapeutic strategies against glioma are urgently required. Substance P (SP), through the neurokinin (NK)-1 receptor, controls cancer cell proliferation by activating c-myc, mitogenactivated protein kinases, activator protein 1 and extracellular signal-regulated kinases 1 and 2. Glioma cells overexpress NK-1 receptors when compared with normal cells. The NK-1 receptor/SP system regulates the proliferation/migration of glioma cells and stimulates angiogenesis, triggering inflammation which contributes to glioma progression. In glioma cells, SP favors glycogen breakdown, essential for glycolysis. By contrast, in glioma, NK-1 receptor antagonists block the proliferation of tumor cells and the breakdown of glycogen and also promote the death (apoptosis) of these cells. These antagonists also inhibit angiogenesis and exert antimetastatic and anti-inflammatory actions.Objective:This review updates the involvement of the NK-1 receptor/SP system in the development of glioma and the potential clinical application of NK-1 receptor antagonists as antiglioma agents.Conclusion:The NK-1 receptor plays a crucial role in glioma and NK-1 receptor antagonists could be used as anti-glioma drugs.
The Underlying Role of Oxidative Stress in Neurodegeneration: A Mechanistic Review
Authors: Yaribeygi Habib , Panahi Yunes , Javadi Behjat , Sahebkar Amirhossein 
Published: April 2018

Background:
Neurodegeneration is a condition in which progressive loss of function and
structure of neurons occurs. Several lines of evidence suggest that oxidative stress has a central role in
neurodegenerative diseases.

Objective:
The aim was to survey molecular mechanisms underlying the involvement of oxidative
stress in developing different neurodegenerative diseases.

Methods:
Original and review articles were retrieved through a PubMed and Google scholar search
(from 1989 to 2015) using the following key words: “oxidative stress”, “nerve degeneration” and
“neurodegenerative diseases”.

Results:
A comprehensive analysis of the obtained articles confirmed strong involvement of oxidative
stress in the pathophysiology of neurodegenerative diseases through a variety of mechanisms including
induction of oxidation of nucleic acids, proteins and lipids, formation of advanced glycation end
products, mitochondrial dysfunction, glial cell activation, amyloid β deposition and plaque formation,
apoptosis, cytokine production and inflammatory responses, and proteasome dysfunction.

Conclusion:
Regarding the pivotal role of oxidative stress in neurodegeneration, modulation of free
radical production or alleviating their harmful effects can be considered as a potential therapeutic
strategy for preventing and controlling neurodegenerative diseases. Accordingly; boosting endogenous
antioxidant capacity besides providing exogenous sources of antioxidants merits future research in order
to discover new therapeutic agents.

Published: April 2018

Background:
Edema represents one of the earliest negative markers of survival and consecutive
neurological deficit following stroke. The mixture of cellular and vasogenic edema makes treating
this condition complicated, and to date, there is no pathogenically oriented drug treatment for edema,
which leaves parenteral administration of a hypertonic solution as the only non-surgical alternative.

Objective:
New insights into water metabolism in the brain have opened the way for molecular targeted
treatment, with aquaporin 4 channels (AQP4) taking center stage. We aimed here to assess the
effect of inhibiting AQP4 together with the administration of a neurotropic factor (Cerebrolysin) in
ischemic stroke.

Methods:
Using a permanent medial cerebral artery occlusion rat model, we administrated a single
dose of the AQP4 inhibitor TGN-020 (100 mg/kg) at 15 minutes after ischemia followed by daily
Cerebrolysin dosing (5ml/kg) for seven days. Rotarod motor testing and neuropathology examinations
were next performed.

Results:
We showed first that the combination treatment animals have a better motor function preservation
at seven days after permanent ischemia. We have also identified distinct cellular contributions
that represent the bases of behavior testing, such as less astrocyte scarring and a larger neuronalsurvival
phenotype rate in animals treated with both compounds than in animals treated with Cerebrolysin
alone or untreated animals.

Conclusion:
Our data show that water diffusion inhibition and Cerebrolysin administration after focal
ischemic stroke reduces infarct size, leading to a higher neuronal survival in the peri-core glial scar region.
Animal, Human and Robot Attribution: Ontologization of Roma, Romanian and Chinese Groups in an Italian Sample
Authors: Pivetti Monica , Di Battista Silvia , Pesole Milena , Di Lallo Antonella , Ferrone Benedetta , Berti Chiara 
Published: April 2018

Background:
The socio-psychological ontologization approach focuses on the attribution of a different “ontology” to outgroup members, that is the attribution of animal (or natural) attributes to the outgroup, and human (or cultural) attributes to the ingroups.

Objectives:
This study aims to enrich the ontologization approach in two ways: (1) A theoretical development of the ontologization approach is proposed, by including the attribution of the essence of automata to outgroup members; (2) whether the ontologization process is also verified for the Romanian and Chinese group is investigated, whereas the ontologization process has traditionally focused on the Roma minority.

Methods:
This study explores the ontologization process of an ingroup member, a Roma, Romanian and Chinese immigrant target via the attribution of a set of six randomly ordered animal, human and robot associates to one of the four targets (N = 269). We tested the idea that devaluation of Chinese immigrants relies on a mechanistic form of ontologization, instead of an animalistic one, such as the case for the Roma and Romanian groups.

Results:
The study confirms the animalization of Roma and Romanian targets in Italy. Both groups were ontologized by attributing animal-like associates to them and denying human-like associates. The Chinese target was ontologized based on a mechanistic approach as it was attributed a more automata-like dimension than an animal or human dimension.

Conclusion:
The pattern of the results regarding the association between the Roma and Romanian outgroup and animal-status may have negative consequences for intergroup relations in terms of reduced prosocial and increased antisocial behaviours.

Published: April 2018

À l'heure où les médias s'emparent des questions de gouvernance et de gestion des migrations irrégulières, de plus en plus d'études sociologiques et anthropologiques tentent de déconstruire les idées reçues, notamment sur l'emploi. Nous examinerons ici les manières dont des migrants sans-papiers, originaires de l’Afrique Subsaharienne, trouvent du travail en France. Il s'agira de démontrer comment les « identités de papiers », définissant un individu comme « protégé », « étranger » ou « national », témoignent d'un espace économique dédié à ces travailleurs, au travers d'interstices de jeux favorisant la négociation des différentes relations en jeu au sein du marché du travail. En s'inspirant de la notion de « jeux de vérité », au sens de Michel Foucault, nous essayerons alors de dévoiler, de manière originale, comment les niveaux interstitiels de jeux amènent à soulever la question des nombreux rapports de force opérationnels dans la définition des situations de travail et dans la régularisation des sans-papiers.
Oswald de Andrade: poesia e psicanálise / Oswald de Andrade: poetry and psychoanalysis

Published: April 2018

ResumoOswald de Andrade, importante artista do Modernismo brasileiro, fez de sua poesia e do seu pensamento inventivo o caminho para denunciar a massificação das idéias vigentes em sua época e a importância da crítica no processo de transformação social. A radicalidade da poesia de Oswald de Andrade é fator de certo estranhamento até os dias atuais, o que nos leva a uma interlocução com a psicanálise, através do texto O Estranho (1919), de Sigmund Freud. Esse estranhamento frente ao que não encontra uma resposta imediata é a chave para abrirmos interrogações sobre a massificação dos modos de sentir e de viver.Palavras-chave: Oswald de Andrade; poesia; psicanálise; utopia. AbstractThe important Brazilian Modernist artist Oswald de Andrade used his poetry and in­ventive thought to denounce the mass vulgarisation of the ideas of his time and to proclaim the importance of critique within the process of social transformation. The radicalism of Oswald de Andrade's poetry evinces to this day a certain alienating effect which compels us to confer with psychoanalysis and its articulation of the Freud’s text, The Stranger (1919). The estrangement which does not offer an immediate answer is the key to further questioning the mass vulgarisation of modes of feeling and living.Keywords: Oswald de Andrade; Poetry; Psychoanalysis; Utopia.
