Programa Bracero y Guerra Fría: auge y declive, 1942–1964
Authors: Vézina Catherine 
Published: March 2018

El Programa Bracero, creado por Estados Unidos y México en 1942 durante la Segunda Guerra Mundial, se mantuvo hasta 1964. Los estudios sobre este programa señalan la importancia de los intereses domésticos de Estados Unidos para explicar la longevidad del mismo. El presente artículo se enfoca en los factores estratégicos propios de la lógica de la Guerra Fría que intervinieron en la decisión de mantener o cancelar este programa bilateral de trabajo temporal agrícola. Mediante un examen atento sobre la época del auge y del declive del programa, se replantean estos debates dentro del contexto nacional, pero también bilateral y panamericano.
The Bracero Program, created by the United States and Mexico during the Second World War, survived until 1964. Studies that look at this program generally signal the importance of domestic factors in the United States to explain its longevity. This article analyzes dynamics of Cold War logic that played a role in the decision of whether to maintain or cancel this bilateral program for migratory agricultural work. By carefully examining the rise and fall of the program, these debates are reconsidered within a national context, as well as one that is bilateral and Pan-American.

Authors: Mansoorinasab Mohamad , Abdolhoseinpour Hesam 
Published: March 2018

Background
Vertebral fractures (VFs) are the most usual convolution of metastatic tumors and the vertebral column is the third most ordinary site for painful bone metastases and remains a chief factor of morbidity in cancer patients.

Methods
In this paper, we investigated the previous literature on the status of clinical and prospects for the use of percutaneous vertebroplasty (PVP) with polymethylmethacrylate as a remedial alternative for the therapy of refractory pain resulting from malignant vertebral compression and pathologic fractures associated with metastatic tumors of various sites in numerous studies. The scientific document for this remedy, containing safety, immediate and long-term efficacy, and outcome measures, and also the risks of complications, was analyzed in detail.

Results
PVP is a safe, feasible, reliable, effective, and useful procedure, a minimally invasive treatment, and a significant tool for reduction of pain and the relief of pain symptoms.

Conclusions
This method can be employed as a further or narcotic remedy in elected patients. The techniques of PVP present a novel alternative therapy for diverse metastases with potentially large application.

Published: March 2018

An 88-year-old male patient of high surgical risk was presented with left sciatic pain symptoms and a palpable pulsatile left lower abdominal mass. He was operated 8 years ago for a large infrarenal aortic aneurysm. Computed tomography angiography (CTA) revealed a giant 161 mm left internal iliac aneurysm with multilocular appearance and left sacral bone erosion causing the symptoms. Endovascular repair was successfully performed using a monotubular iliac stent-graft. Follow-up CTA showed absence of contrast enhancement and a fully thrombosed sac. Patient recovered completely and was discharged 1 month after the procedure in a relatively good condition, nevertheless sciatic symptoms remained.

Published: March 2018

Aim
This study aims to establish the isolation method of stem cells from pulp tissue of carious deciduous teeth.

Methods
The teeth were soaked in 1% povidone–iodine solution for about 1 min followed by washing in PBS with 1% antibiotic–antimycotic thrice. Dental pulp tissue was removed by extirpation, and then cultivated in the culture medium. Characterization of mesenchymal stem cell (MSC) was carried out using human MSC analysis kit with positive markers CD90, CD73, and CD105, but negative for expressions of CD45, CD34, CD11b, CD19, and HLA-DR. Differentiation capacity of stem cells from human exfoliated deciduous (SHED) was determined by staining with Alizarin S, Alcian Blue, and Oil Red O.

Results
There is no contamination after 3 days of culture. SHED derived from dental pulp were expressions of 99.2% of positive marker and 0.3% of the negative marker. At passage 5, SHED was differentiated into osteocyte, chondrocyte, and adipocyte types of cells in the induction medium.

Conclusion
SHED derived from carious deciduous teeth can be used as a source of stem cell for regenerative medicine.
Paraoxonase 1 activities and its gene promoter single nucleotide polymorphisms (-108, -126, and -162) in diabetes mellitus
Authors: Emami Asefesadat , Tajadini Mohamadhasan , Zeinalian Mehrdad , Keshvari Mahtab , Asgary Sedigheh 
Published: March 2018

Background
Paraoxonase 1 (PON1) enzyme is known enzyme with, aryl esterase, phosphatase, peroxidase, and lactonase activities. According to some studies, the activity of PON1 enzyme is decreased in type 2 diabetic patients. We analyzed the enzyme activity and its single nucleotide polymorphisms (SNPs) distribution on promoter regions (-108, -126, and -162) in type 2 diabetic patients compared with non-diabetic individuals to reveal the likely relationship between PON1 activity and its gene promoter polymorphisms.

Methods
On the whole, 98 diabetic and 104 non-diabetic individuals were examined in this study. The enzyme activity and the genotypes were studied using spectrophotometry, real-time PCR-HRM, and sequencing techniques, respectively.

Results
There was no meaningful difference in enzyme activity between two under-studied groups (P.V = 0.671). Moreover, no meaningful difference was also seen between two groups in terms of the frequency of polymorphism -108 (P.V = 0.277). The frequencies of SNPs -126 and -162, however, showed a meaningful difference between two groups (P.V = 0.000 and P.V = 0.017, respectively).

Conclusions
We indicated PON1 activity could be similar in DM-2 patients and non-DM-2 individuals. The significant role of SNP -108 in PON1 activity in DM-2 patients compared with non-DM-2 individuals was confirmed in the study too. On the other hand, the role of -162 and -126 SNPs in causing diabetes cannot be easily overlook because of a meaningful difference of their distribution in understudied groups. However, they may be attributed to DM-2-associated genes.
Técnicas de remediación de metales pesados con potencial aplicación en el cultivo de cacao.
Authors: Casteblanco Javier Andrés 
Published: March 2018

El cacao (Theobroma cacao) a nivel mundial ha aumentado su área sembrada y rendimiento por hectárea, sin embargo actualmente los productores se enfrentan a una fuerte legislación emanada por la Unión Europea respecto a los contenidos máximos de plomo y cadmio que deben tener los chocolates que contienen una cantidad mayor o igual al 50% de sólidos de cacao. En base a una revisión de los trabajos realizados alrededor del mundo y que han sido publicados en los últimos tres años en bases de datos mundiales se presentan en primera instancia los problemas ocasionados en las personas por el consumo de alimentos contaminados por metales pesados y las rutas a través de las cuales se puede contaminar el cacao, desde su siembra hasta su procesamiento. A continuación y dando cumplimiento a el objetivo de la revisión se muestran las técnicas de remediación (fitoremediación y bioremediación) que han obtenido buenos resultados respecto a la limpieza de suelos contaminados o que evitan la traslocación de los contenidos de plomo y cadmio del suelo a varios cultivos de interés comercial para tener opciones de potencial aplicación en las zonas cacaoteras de Colombia o cualquier parte del mundo. De los resultados obtenidos se resalta la importancia que tiene la implementación de un sistema integrado de remediación de suelos que incluya la incorporación gradual de árboles nativos, plantas herbáceas, plantas acuáticas, biochar, bacterias y micorrizas arbusculares.

bezlerinde yerleşen ağrılı, akıntılı apse oluşumları, sinüs, fistül ve skarlar
ile çevre dokulara yayılan tekrarlayıcı bir hastalıktır. Etyolojisi kesin olarak bilinmemekle birlikte
genetik yatkınlık, hormonal faktörler, obezite ve sigara kullanımı suçlanan
faktörlerdir. Erken dönem lezyonlara medikal tedavi uygulanırken, kronik,
komplike olgularda tedavi cerrahidir. Bununla birlikte nüksler görülebilir ve
reeksizyon gerekebilir. Bu çalışmada farklı anatomik bölgelerde bulunan ve
klinik olarak farklı güvenlik sınırıyla eksizyon uygulanmış hidradenitis süpürativa
olgularındaki nüks ve diğer komplikasyon oranlarının araştırılması
amaçlanmıştır.

Gereç
Ve Yöntemler: Bu çalışmada Ocak 2000- Mart 2017 tarihleri arasında plastik
cerrahi polikliniğine müracat eden, medikal tedaviye dirençli, kronik,
rekürrens gösteren ve cerrahi tedavi uygulanan 45 hasta lezyonların yerleşim
yeri, uygulanan cerrahi yöntemler ve komplikasyonlar açısından retrospesifik
olarak değerlendirildi. Hastaların 25’i erkek, 20’si kadın ve yaş ortalaması 36,7
idi (15–78).

Bulgular
: Hidradenitis süpürativalı hastaları tedaviye yönlendiren temel sebep yaşam
kalitesinin bozulması ve psikolojik sorunlara kadar uzanan sağlık problemlerine
sebep olmasıdır. Hidradenitis süpürativa’da tedavi hastalığın bulguları ve

olan 3 hastada lezyon sınırında yapılan
eksizyonlar sonrası nüks görüldü. Toplamda hastalarda nüks oranı %11,1 olarak
tespit edildi ve bu hastalara daha geniş cerrahi sınırla reeksizyon yapıldı. Bu
çalışmanın amacı hidradenitis süpürativa tedavisinde geniş ve derin cerrahi
eksizyonu önemini vurgulamaktır.
Sociolinguística, teoria social e padronização linguística
Authors: Santos Marcos Bispo 
Published: March 2018

Resumo: Neste artigo, questiona-se a pertinência e a relevância da sociolinguística variacionista como ciência aplicada na abordagem de questões relativas à padronização linguística no Brasil. Para isso, fez-se uma pesquisa bibliográfica dividida em dois eixos, o linguístico e o sociológico, com o intuito de compreender as bases teóricas da sociolinguística brasileira. No primeiro eixo, buscou-se compreender a natureza da sociolinguística com base nas pesquisas de Labov. No segundo, situou-se o componente propriamente sociológico da sociolinguística no contexto das teorias sociais. A análise evidenciou que a metodologia da pesquisa, no contexto da sociolinguística variacionista, é marcadamente positivista e não se coaduna com os princípios da pesquisa social contemporânea. Verificou-se ainda que a tese da ideologia dominante, elemento central da teoria social da sociolinguística brasileira, além de não exercer influência significativa na metodologia da pesquisa, já foi amplamente questionada e não exerce influência na pesquisa social contemporânea.Palavras-chave: padronização linguística; sociolinguística variacionista; teoria social.Abstract: In this article, we discuss the pertinence and relevance of Brazilian variationist sociolinguistics as applied science in the approach of issues related to linguistic standardization. In order to do so, we conducted a bibliographical research divided into two axes, the linguistic one and the sociological one, aiming at understanding the theoretical bases of Brazilian sociolinguistics. In the first axis, we discussed the nature of sociolinguistics taking Labov’s research as a starting point. Then, we situated the sociological component of sociolinguistics in the context of Social Theories. The analysis showed that in the context of variationist sociolinguistics, the research methodology is markedly positivist and does not conform to the principles of contemporary social research. We also observed that the Dominant Ideology Theory, a central element in the social theory of Brazilian sociolinguistics, not only did not exert significant influence in the methodology of the research works carried out in the area, but also had already been widely questioned in the context of social research and does not present satisfactory answers to the problems it is supposed to explain.Keywords: linguistic standardization; variacionist sociolinguistics; social theory.

Saliva Leptin Levels in Tooth Movement during Initial Stage of Orthodontic Alignment: A Pilot Study
Authors: Bakar Noraini Abu , Kamil Wisam , Al Bayati Lina , Mustafa Basma Ezzat 
Published: March 2018

Introduction: During orthodontic tooth movement, the early response of periodontal tissues to mechanical stress is an acute inflammatory reaction. Mechanical stress from orthodontic appliances is believed to induce cells in the periodontal ligament (PDL) to form biologically active substances, such as enzymes and cytokines, responsible for connective tissue remodeling (Nishijima Y et al 2006). Leptin, a polypeptide hormone has been classified as a cytokine (Zhang et al 1994). Earlier findings concluded that leptin at high local concentrations protects the host from inflammation and infection as well as maintaining bone levels. It has been also suggested that leptin plays a significant role in bone formation by its direct effect on osteoblasts (Alparslan et al 2010). This pilot study aimed to study leptin in saliva and its association with tooth movement during initial orthodontic alignment. Objectives: To determine if there are any differences in saliva leptin level before and after orthodontic alignment. Material and methods: Ten orthodontic patients (7 girls and 3 boys; mean age, 16.76 ± 1.1 years) with crowding (up to 5mm) that required orthodontic fixed appliances, on a non-extraction basis as part of the treatment plan, were recruited in this longitudinal study. Orthodontic study models were constructed at baseline and at 6- weeks after orthodontic treatment commenced. Full fixed orthodontic appliances with initial 0.014” Nickel Titanium archwire placed. The amount of crowding was measured, before and after initial alignment with an electronic digital caliper (Max-Cal, Japan Micrometer Ltd, Tokyo, Japan) with an accuracy of up to 0.01mm. Unstimulated morning saliva sample were collected at all visits, after at least an 8-hour period of fasting and no-toothbrushing. After centrifugation (4000x g;10min), the samples were stored at -25C and tested using Leptin Abnova LEP Human ELISA kit (KA3080) which was subsequently analyzed. Subjects’ periodontal health status was also monitored throughout the study. Ethical approval (ID IREC 262) was received on 7th April 2014 from International Islamic University Malaysia Research Ethics Committee (IREC). Results: Leptin concentration in saliva was significantly decreased in a time-dependant manner (t(9)=8.60, p<0.001), from before orthodontic treatment (7016.45± 425.15 pg/mL) and 6 weeks after bond-up (4901.92± 238.64 pg/mL). Conclusion: Leptin concentration in saliva is decreased during orthodontic tooth movement in initial alignment stage.
