Background: Birth asphyxia in neonates significantly contributes to their mortality and morbidity, as it leads to hypoxic ischemic encephalopathy (HIE) and multi organ dysfunction. The present study was conducted with an objective to ascertain whether serum levels of creatinine kinase muscle-brain fraction (CK-MB) and lactate dehydrogenase (LDH) can distinguish an asphyxiated from a non-asphyxiated term neonate and correlation of these enzymes cut-off levels with severity of HIE in asphyxiated term neonates.Methods: This prospective study was conducted at Sree Mookambika Institute of Medical Sciences, Kulasekharam, Kanyakumari from September 2012 to December 2013. The study included 50 cases (asphyxiated neonates) and 50 controls (non-asphyxiated neonates) after fulfilling the requirements of inclusion criteria. Their blood samples were collected at 8±2 hours and 72±2 hours of age for estimation of CK-MB and LDH respectively and sent for analysis. The values were compared between cases and controls by using descriptive statistics.Results: The mean CK-MB level at 8±2 hours and mean LDH level at 72±2 hours were significantly higher in cases compared to controls with p<0.001. Among the 50 neonates in case group, 19 (38%) had clinical evidence of HIE. Of them 3 (6%) had mild HIE, 12 (24%) had moderate HIE and 4 (8%) had severe HIE during the course in NICU. The correlation of Apgar scores of 0-3 and 4-6 at 1 minute and 5 minutes with the severity of HIE and the correlation of cut-off CK-MB level of 92.6 U/L and cut-off LDH level of 580 U/L with the severity of HIE were not significant (p>0.05).Conclusions: We conclude that estimating the levels CK-MB at 8 hours of life and LDH at 72 hours of life can help to distinguish an asphyxiated from a non-asphyxiated term neonate with reasonable degree of accuracy but the enzyme cut-off levels do not correlate with severity of HIE in asphyxiated term neonates.

African catfish (Clarias gariepinus) is one of the economically valuable aquaculture fish species in Indonesia. This research was aimed to produce F0 transgenic catfish carrying masou salmon Δ6-desaturase-like (OmΔ6FAD) gene. The Δ6-desaturase enzyme is involved in highly unsaturated fatty acid biosynthesis. Transgenic catfish was produced by sperm-mediated gene transfer using electroporation method. In this study, as the first step, sperms were electroporated with three different OmΔ6FAD concentration (25, 50, and 100 µg mL-1) to have the highest sperm viability after electroporation (125 V/cm, pulse frequency 5 times, pulse length 30 millisecond, pulse interval 0.1 second). The highest sperm viability and sperm carrying OmΔ6FAD were obtain at 100 µg mL-1. This concentration was then used to produce F0 transgenic catfish in the second step. Sperm motility, sperm viability, fertilization rate, hatching rate, and larval survival at 14 days after hatching were the same as the controls (p>0.05). Genomic DNA was extracted from caudal fin and then used as template to identify transgenic F0 by PCR method using specific primer for OmΔ6FAD gene. The PCR result showed that 53.84% of F0 carried OmΔ6FAD gene. The result of fatty acid analysis showed that EPA and DHA contents of F0 transgenic fish and non-transgenic fish were similar.

A ESCRITA NA AFASIA: DA PERDA À RECONSTITUIÇÃO DA LINGUAGEM
Authors: Pereira Lima Carvalho Magda Wacemberg , Da Silva Gonçalves de Azevedo Nadia Pereira 
Published: February 2018

Considerando que na afasia o quadro sintomático de linguagem é marcado pela “insistência/persistência de uma diferença” (LIER­-DE VITTO, 2006, p. 186, grifos da autora), este trabalho tem como objetivo compreender o processo de reconstituição da escrita de um sujeito em estado de afasia, cuja linguagem foi gravemente perturbada. De natureza exploratória com abordagem qualitativa, a pesquisa tem como corpus seis textos produzidos durante o período em que o sujeito esteve hospitalizado. O aporte teórico advém fundamentalmente de estudiosos da Afasiologia, da Aquisição e das Patologias de Linguagem, dentre os quais estão Freud ([1891] 1977; 2012); Jakobson ([1954] 2008); Morato (2012; 2013); Santana (2002); Lemos (1992; 2002; 2006); Lier-De Vitto (2006); Arantes (2006; 2009); Borges (2006; 2010); e Bosco (2010). Os resultados revelaram que o movimento de (re) composição da escrita do sujeito em questão foi marcado pela interação com o outro (terapeuta ou familiar), que como portador do texto-discurso conduziu o sujeito à escrita; significou e interpretou seus textos, por meio de atividades que envolviam situações cotidianas, (re) inserindo-o, com isso, no funcionamento linguístico-discursivo.
Predicting Geomechanical Dynamics of the Steam-Assisted-Gravity-Drainage Process. Part I: Mohr-Coulomb (MC) Dilative Model
Authors: Irani Mazda 
Published: February 2018

Summary
In the steam-assisted-gravity-drainage (SAGD) recovery process, the injection of high-pressure/high-temperature steam causes significant stress changes at the edge of the heated zone or steam chamber. These stress changes include shear dilation, which can both enhance the absolute permeability and result in horizontal and vertical formation displacements. The importance of considering geomechanical effects in thermal-recovery processes has been extensively discussed in the literature, but the prediction and surveillance of the resulting effects, such as the impact on production enhancement and reservoir displacement, have in many cases been neglected. Furthermore, issues related to these geomechanical effects on thermal production have been the subject of considerable debate in the industry with no conclusive, meaningful assessments of the effect on reservoir deliverability and production, or of the associated risks that such geomechanical effects have on wellbore and caprock integrity.
This study will focus on identification of the main findings from an extensive monitoring program conducted on the original SAGD pilot project conducted at the Underground Test Facility (UTF) in the late 1980s and a seismic program conducted during the last several years by an SAGD operator at a commercial thermal-recovery project. The measured displacements and identified dilation shear zones in these applications were compared with a Mohr-Coulomb (MC) dilative model. This paper illustrates some of the pros and cons of using such analytical models through comparison of the results based on field evidence of the dilation and shearing effects, and how these mechanisms affect both reservoir productivity (revenue) and wellbore and caprock integrity. Although the discussion on the geomechanical effects in thermal-recovery processes will no doubt continue, this study will provide field-supported results to illustrate both beneficial and potentially challenging impacts that these geomechanical effects can have in a thermal-recovery project.

Authors: Al-Tannak Naser F. , Al-Hasawi Nada A. , Novotny Ladislav 
Published: February 2018

Background:
Flavonoids as secondary metabolites of plants fulfill various functions in cell
protection. They are of a considerable scientific interest because of their potentially medical use due to
their anticancer, chemoprotective, antimicrobial, antiallergic, anti-inflammatory and antiviral activities.
</P><P>
Objective: The study aimed to develop a new UHPLC-UV method for morin and 2 other structurally
related flavonoids - naringenin and kaempferol as the structural similarity of huge numbers of flavonoids
does not limit their various biological functions and activities.

Methods:
Separation of morin and 2 other structurally related flavonoids - naringenin and kaempferol -
was achieved by using BEH C18 (1.7 µm, 2.1 x 50 mm) analytical column (Waters® Acquity UPLC)
and a mobile phase composed of 0.05%v/v Formic acid in water and acetonitrile in proportion of 77:23
v/v and pumped at a flow rate of 0.4 ml/min. Column temperature was set at 25 ºC and samples were
analyzed (3 µl injection volume) at a wavelength of 340 nm. Waters® Xevo G2-S QToF coupled with
Waters® Acquity UPLC system with binary Solvent Manager (I-Class) via electrospray ionization (ESI)
interface was used to confirm the identity of the peaks in biological samples.

Results:
A rapid and simple UHPLC-UV separation of morin, kaempferol and naringenin is documented
including methods validation. The developed method was applied to measuring morin,
kaempferol and naringenin in human plasma after a solid phase extraction. Additionally, stability of
morin in tissue culture medium was verified. The extraction method and UHPLC-UV elution conditions
described provide a practical means to analyze morin, kaempferol and naringenin in biological matrices.

Conclusion:
The developed method is fast and highly sensitive. Moreover, the flavonoids used were
stable in human plasma for more than 10 days.
