Authors: Caviedes Pérez Giovanni , Gutiérrez Olaya Natalia , Mosquera Villareal Orlando
Published: March 2018

El uso indiscriminado de medicamentos en las gestantes, hace que se deba realizar una vigilancia estricta, debido a los múltiples riesgos tales como malformaciones fetales y aumento en la morbimortalidad matera y fetal. El problema fundamental radica en la ausencia de estudios clínicos controlados en este tipo de población debido a razones éticas. Se realizó un estudio observacional descriptivo de corte trasversal de periodo, tomando las gestantes que acudieron a la unidad materna de la ESE Carmen Emilia Ospina en el tiempo comprendido entre el 1 de septiembre del 2011 hasta el 29 de febrero del 2012. El propósito del estudio fue caracterizar epidemiológicamente la utilización de medicamentos en las pacientes gestantes y establecer posibles factores asociados a su uso. Se consideraron casos aquellas pacientes que recibían medicamentos de uso no obligatorio en el embarazo y se realizó el análisis estadístico en stata 10,1. Se obtuvo una muestra de 365 pacientes con una mediana de edad de 22 años, la utilización de medicamentos se encontró en un 60%, siendo la automedicación responsable del 16,7%, la categoría farmacológica B se presentó con mayor frecuencia en un 82,8%. El control prenatal adecuado, que hace referencia al cumplimiento de este, acorde con la edad gestacional, se encontró solo en un 63,2% del total de las pacientes; el 78,5% de las gestantes cursaban estudios secundarios. El fármaco de mayor uso fue el acetaminofén en un 30%, seguido de la hioscina en un 18%, la metoclopramida en un 7% y la cefalexina en un 5%. Otros medicamentos tales como el metronidazol, la hioscina más dipirona, la cefradina ranitidina, dipirona fueron usados en menor proporción. Los motivos de prescripción fueron el dolor pélvico y la cefalea en un 29% y 17% respectivamente. Se realizó un analisis multivariado de regresión logística encontrándose que la segunda mitad de la gestación se comporta como factor protector para el uso de medicamentos durante la gestación. Las otras variables identificadas tales como el nivel cultural bajo, la procedencia urbana y la presencia de controles prenatales no mostraron datos estadísticamente significativos. Como conclusión se tiene que el uso de medicamentos en las gestantes es un problema grave de salud que se encuentra plenamente identificado en nuestra región y requiere planes estrategicos claros para su prevención.

Es un estudio analítico de casos y controles basado en la revisión de historias clínicas de las gestantes del programa de control prenatal que asistieron antes y después del primer trimestre de gestación en el periodo comprendido entre septiembre-diciembre de 2009 en la ESE San Sebastián de la Plata - Huila. El objetivo es determinar los factores asociados con la inasistencia al control prenatal durante el primer trimestre. Se estudiaron 139 casos de gestantes con inicio tardío de los controles prenatales y 149 controles. Se realizó el análisis univariado y bivariado mediante el paquete estadístico SPSS versión 19 para Windows. Para estimar el riesgo de inicio tardío de los controles prenatales asociado con los factores de riesgo se calculó el Odds Ratio (OR), y se calcularon intervalos de confianza (IC) al 95%. En los resultados, las edades de las 288 gestantes que acudieron a control prenatal oscilaron entre los 14 y 45 años. El 77,1% de las gestantes pertenecían al régimen subsidiado. Nivel educativo superior a primaria es un factor protector, estadísticamente significativo para quienes lograron terminar la secundaria (OR=1,85, I.C 95%= 1,05-3,14 p=0,015). El riesgo de inicio tardío del control prenatal se incrementó en la medida en que lo hacía el número de embarazos, siendo estadísticamente significativo el antecedente de 4 a 6 gestaciones (I.C 95%: 1,15-5,52; p-valor: 0,011). En conclusión, los principales factores asociados con el inicio del control prenatal después del primer trimestre son embarazo en adolescente, bajo nivel educativo; mujeres con 4 a 6 embarazos previos.

Authors: Omodamiro Olorunshola Dave , Nwankwo Chinedu
Published: March 2018

Chrysophyllum albidum G. is generally regarded as a plant with many ethno-medicinal uses. The study was aimed at evaluating the in vitro antioxidant, diuretic, and hypoglycemic properties of the ethanol extract of leaves of C. albidum Male Wistar albino rats weighing between 150g and 200g were used for the experiment. The DPPH scavenging activity was determined using DPPH assay, inhibition of lipid peroxidation was carried out using the reactions of peroxides with thiobarbituric acid, while nitric oxide was conducted based on the Greiss reaction. Diuretic activity was carried out using the method of Lipschitz with slight modifications. Alloxan (140 mg/kg) was used to induce diabetes in the rats. The extract showed a concentration-dependent increase in DPPH radical scavenging activity, anti-lipid peroxidation activity, and nitric oxide inhibition activity maximal at 200 mg/ml (84.99±7.97, 79.82±6.10, 69.99±2.22 respectively) and this was significant (p<0.05) when compared with that of 100 mg/ml of vitamin C (97.68±0.84, 99.05±0.24 and 98.15±0.29 respectively) which served as the control. The extract also significantly (p<0.05) increased; urine volume, urinary sodium, and urinary chloride particularly at 2000 mg/kg (1.55±0.07, 109.60±0.57, and 106.00±1.41 respectively) when compared with the standard drug (1.85±0.07, 115.20±0.57, and 112.85±0.49 respectively). The increase in potassium excretion was also significant (p<0.05) particularly at 2000 mg/kg (13.70±0.28) but less than those of sodium (109.60±0.57) and chloride (106.00±1.41) at the same concentration. There was no significant (p<0.05) increase in urinary bicarbonate the maximum being at 250 mg/kg (22.55±0.78). The extract caused a non-significant (p<0.05) decrease in the fasting blood glucose level of the rats. It was concluded that the leaves of C. albidum could be used as a source of natural antioxidant boosters and also a diuretic.

Published: March 2018

The objective of the current study was led to reveal the possible protective effects of n-butanol extract of Helianthemum
confertum (H. confertum) against doxorubicin (DOX) induced liver damage and its implication on the integrity of liver
cells. Adult male rats were randomly divided into groups treated with plant extract (50 mg/kg, 100 mg/kg) for 10 days
and/or injected with a single dose of DOX (10 mg/kg). Liver function as well as oxidative stress parameters and histological
study were estimated. DOX treated rat’s induced hepatic dysfunction revealed by a significant increase in biochemical
parameters (serum transaminases, cholesterol and triglycerides) and disturbance in oxidative stress parameters described
by an increase in malondialdehyde (MDA) levels, providing information on the loss of cellular integrity. This later elicited
histopathological changes in the liver which was confirmed on histological section chowing necrotic cells. Altghout the
DOX-treatment reduced significantly the reduced glutathione (GSH) level and the glutathione peroxidase (GPx) activity.
The pretreatment of the animals with n-butanol extract of H. confertumat 50 mg/kg and 100 mg/kg counteracted almost all
adverse effects induced by DOX. The results showed a considerable decrease in serum markers of liver function and lipid
peroxides. There was significant increase in the GSH level and the activity of antioxidant enzyme (GPx), which allowed
the normalization of redox status in liver cells. Data suggest that DOX-induced an oxidative stress in rat’s liver and nbutanol
extract of H. confertum exerted antioxidant properties.

Published: March 2018

Introduction: Herbal drugs constitute a major part in all traditional system of medicine. Researchers have no doubt that
nature is still the preeminent synthetic chemist and that in plants, particularly; there are almost infinite reserves of chemical
constituents with actual and potential effects on human body. The herb Capsicum annuum is a culinary herb and its two
pharmacological properties i.e. lipid lowering and antidiabetic activity are unexplored. This research paper focuses on
hypocholesterolemic and antidiabetic property of capsaicinoids and its further use as an antiobese drug. Experimental
Work: Wister strain of albino rats were divided into four groups comprising of six rats each. Group I served as normal
control fed with normal pellet chow, group II served as disease control fed with high fat diet /diabetogenic diet, group III
and IV animals, received capsaicinoids and standard drug (Atorvastatin / metformin) respectively. The study was carried
out for a period of 9 weeks for hypocholesterolemic and 11weeks for antidiabetic activity. Results: Administration of HFD
or diabetogenic diet for stipulated days to rats significantly increased the body weight, serum total cholesterol, LDL
cholesterol, VLDL cholesterol, triglycerides and glucose levels; and decreased HDL cholesterol as compared to normal
control. Treatment with capsaicinoids/ atorvastatin showed a significant reduction in the body weight gain, and the levels
of serum triglycerides, total, LDL, VLDL cholesterol and increase in HDL cholesterol . However capsaicinoids not only
significantly reduced the cholesterol levels but also reduced the glucose levels which were due to dyslipidemia when
compared with the standard. This was true with antidiabetic activity where the blood serum profiles reduced along with
glucose levels

Published: March 2018

Hypertension has been cited as a major risk factor of morbidity and mortality related to cardiovascular diseases and it is considered a public health problem worldwide. There is a lack of information regarding the real prevalence of hypertension among children and adolescents because blood pressure assessment is not considered part of the routine clinical assessment in this population.The aim of this study was analyze the reported prevalence of hypertension in children and adolescents according gender and nutritional status during the period 2000-2014.Methods: A systematic review focused on the assessment of high blood pressure was conducted. Only original articles were selected on the basis of strict inclusion and details and reviewed by pairs. 98 studies met the inclusion criteria. Computerized searches were completed using multiple databases.Results: Nutritional status strongly influences whether children are more likely to have hypertension. However this condition is not the same for overweight children in the United States that have less hypertension than obese children or the adolescents in Asia that the same effect occur. In the case of sex, it was observed that boys in most of the regions are more likely to have hypertension, however this change in the United States and in Africa where girls suffer more of hypertension. According with the age, there are more cases of hypertension among adolescents  than in children, where Latin America reported the highest level of hypertension.Conclusion: The data indicated that despite differences between regions, childhood hypertension has increased in the course of 14 years and it is higher among boys (36.69%) than girls (35.87%), and is also affect by the nutritional status of individuals (37.29% normal weight, 49.49% obese and 68.55% overweight). The reporting of prevalence among children and adolescents around the world need to be improved considerably in order to diminish the inconsistences.

Published: March 2018

Cancer is a disease that can threaten human life. Various methods of cancer therapy havebeen widely practiced, one of which is chemotherapy. But the cost used for the therapy is alsovery expensive. This difficulty led many researchers to conduct research to find activecompounds from natural materials. Moringa leaf (Moringa oleifera) has cytotoxic activity,because it contains a lot of flavonoids. Flavonoids are polyphenol compounds produced fromsecondary metabolism in plants. The most flavonoids that are anticancer active substances inthe Moringa leaf are quercetin, kaempferol and myricetin. Cytotoxic activity because theseactive substances can induce apoptosis through intrinsic pathways by inhibition of mitogen-activated protein kinase (MAPK), extracellular-signal-regulated kinase 1/2 (ERK 1/2), c-Jun N-terminal protein kinase 1 (JNK), and protein kinase C (PKC).Keywords: Moringa leaf, quersetin; kaempferol; myricetin; anticancer

Meningioma is an intracranial tumor that generally involves meninges. This tumor canbe found along the dura layers at the skull base. Meningioma has vast vascularization from thearteries near dura attachment. Pre-operative embolization technique is an effective strategy toprevent intra-operative complications and better outcomes. The patient was a 24 year-oldwoman who has been complaining of headaches since 2 months ago. The CT Scan resulted in a12 x 9 x 7 cm isodense mass in the left temporoparietal enhanced homogenously by contrast.Pre-operative embolization was performed on the tumor feeding artery as a strategy to preventintra-operative blood loss. A left frontotemporosphenoidal craniotomy was performed 10 daysafter embolization to remove the tumor. A complete resection was successfully achieved withless intraoperative blood loss and without complication. The pathology examination resulted inmeningotheliomatous meningioma. A follow-up picture showed no recurrent tumor afterresection and the patient had no symptoms and neurological deficits until 6 months after thesurgery. In conclusion, meningioma is a common intracranial tumor with a lot of blood supply.However, tumor resection can be safely and efficaciously performed with good pre-operativestrategy.Keywords: brain tumor, embolization, meningioma, resection, skullbase

Published: March 2018

Radiation pattern of Yagi-Uda antenna is elliptical. This pattern can be used as a detector for the direction of the source of a radio emission. A total of nine Yagi-Uda antennas fitted with a 3x3 configuration. With this configuration, the measurement range for azimuth and elevation angles can reach 80º. The simulation was performed by using an antenna radiation pattern data. The number of antennas used for this simulation is nine. Then the data is merged into a 3x3 antenna configuration data. Based on data from nine antenna radiation patterns, the algorithm for the estimation of azimuth and elevation angles can be applied. Simulation results show that the measurement error of the signal without noise is close to zero. The algorithm used in this simulation can be applied to noise below 25%.

Published: March 2018

Since the conceptual design phase, the estimate of airplane life cycle cost (LCC) is carried out to support a decision making process. The LCC consist of research, development, testing, and evaluation cost, where an airplane estimated price (AEP) is a part of this calculation. Furthermore, AEP is employed as a non linear objective funtion for developing a constrained optimization algorthm. Rosen’s gradient projection is applyed in the development of computer program named Cost Analysis implementing object oriented approach on Microsoft Visual C++ 6.0. In order to verify the application, some data of Ourania jet airplane were utilized for carrying out a case study. The result of Cost Analysis shows that the estimated LCC are similar to the reference. Also, the optimization problems can be solved by Rosen’s algorithm less than ten iterations.

Published: March 2018

This paper discusses the development of a computer software for simulating and analyzing flight trajectory of rocket systems. Many aspects may influence the trajectory, such as those related to the internal characteristic of the system, those representing external or environmental influence, and also the ones corresponding to the procedures of the launching and the operation during its flight. The software is developed based on the mathematical equations representing the balance of forces and moments occur during the flight of a rocket. Some conditions related to rocket internal characteristic variation, external perturbance, and flight procedure/operation are represented as parameters variations of the mathematical equations used for computing the rocket system attitude and movement variables. The software, developed using MATLAB/ SIMULINK application, is then used for simulating and analyzing the flight trajectory of a multi-stage rocket in some flight conditions. At this development stage, as the simulation results show, the software can perform its function quite well to compute the system variables during each of its flight phases and display the information required for further analysis. In future development, some validation tests still need to be accomplished for ensuring the accuracy and validity of the method used in this software.

Authors: Dewi Wiwiek Utami
Published: March 2018

Decomposition of propellant Mechanism and kinetics have been investigated by using DTG/TA with three different methods: Kissinger, Flynn Wall Ozawa and Coats & Redfern. This research aims to determine decomposition kinetic parameters of LAPAN’s propellant. The propellants have different composition of Al and AP modal. RUM propellant consist of AP/HTPB. 450 propellant consists AP/HTPB/Al (bimodal). Meanwhile 1220 propellant consists of AP/HTPB/Al (trimoda). Thermal analysis takes place at 30 – 400oC and nitrogen atmosphere flow rate is 50 ml/min. The result according showed that propellant was decomposed by F1 mechanism (random nucleation with one nucleus on the individual particles). Activation energy of propellants are in range between 100.876 – 155.156 kJ/mol meanwhile pre-exponential factor are in range between 4.57 x 107 – 3.46 x 1012/min. Activation energy (E) as well as pre-exponential factor for 1220 propellant is the lowest among the others. AP trimodal application generates catalytic effect which decreases activation energy. 1220 propellant is easier to decompose (easier to react) than RUM and 450 propellant. AbstrakMekanisme dan kinetika dekomposisi propelan telah diinvestigasi menggunakan DTG/TA dengan tiga jenis metode yang berbeda yaitu Kissinger, Flynn Wall Ozawa dan Coats & Redfern. Penelitian ini bertujuan untuk mengetahui parameter kinetika dekomposisi propelan LAPAN. Propelan yang digunakan memiliki perbedaan komposisi Al dan jenis moda AP. Propelan RUM adalah propelan AP/HTPB. RX 450 adalah AP/HTPB/ Al (bimoda). Sementara itu, RX 1220 adalah AP/HTPB/ Al (trimoda). Pengujian termal berlangsung pada suhu 30 - 400oC dan atmosfer nitrogen berlaju alir 50 ml/menit. Hasil penelitian mengungkapkan bahwa semua jenis propelan terdekomposisi dengan mekanisme F1 (nukleasi acak dengan satu nukleus pada partikel individu). Energi aktivasi propelan berkisar antara 100,876 – 155,156 kJ/mol sementara faktor pre-eksponensial berkisar antara 4,57 x 107 – 3,46 x 1012/min. Energi aktivasi (E) dan faktor pre-eksponensial (A) RX 1220 adalah terendah dari ketiga sampel. Penggunaan jenis AP trimodul menciptakan efek katalitik yang menurunkan besarnya energi aktivasi. Propelan RX 1220 lebih mudah terdekomposisi (lebih mudah bereaksi) daripada propelan RUM dan RX 450.

El enfoque sociocrítico: ¿una perspectiva de investigación en vía de extinción?
Authors: Cristancho Altuzarra José Gabriel
Published: March 2018

Este trabajo analiza y sistematiza algunas de las experiencias cotidianas que implica el proceso de investigación con el ánimo de responder la pregunta por las condiciones de posibilidad del enfoque sociocrítico en la época contemporánea y contribuir al horizonte de debate y discusión en torno al quehacer investigativo. La cuestión se aborda en dos momentos: en el primero, se analizan algunas de las condiciones materiales, culturales y sociales de la investigación, pues se parte de la hipótesis de que estas condiciones van configurando unas formas de neutralización y desestimación del enfoque sociocrítico a nivel práctico y a nivel epistemológico. En la segunda parte se plantean algunas condiciones de posibilidad para que este enfoque se desarrolle y posibilite formas de construcción del conocimiento alternativas, planteando una segunda hipótesis: el enfoque sociocrítico, epistemológicamente fundamentado, es un puente para la construcción del conocimiento transdisciplinariamente; en suma, es una perspectiva que ayudaría a aunar esfuerzos de las ciencias naturales y aplicadas y de las ciencias sociales y humanas en los ámbitos de la universidad de investigación, currículo y proyección social.

Este artigo discute e apresenta possíveis potencialidades do uso de elementos da Semiótica Peirceana como instrumento para tratar do estatuto ontológico e epistemológico do papel das representações no Ensino de Química.  Busca-se apresentar uma abordagem que leve em consideração o plano ontológico e o plano linguístico na discussão sobre a representação em Química e no Ensino de Química. Defende-se que na perspectiva da semiótica de Peirce é possível avançar nas discussões sobre o estatuto ontológico da representação.
QUÍMICA PARA DAMAS: los instructivos y elegantes diálogos de Jane Marcet (1806)
Authors: Trindade Lais Santos Pinto , Beltran Maria Helena Roxo
Published: March 2018

Este estudio analiza el influyente papel de la mujer en la conservación, transmisión y difusión de los conocimientos sobre la materia, focalizando especialmente la obra Conversations on Chemistry (1806) de Jane Marcet. Aunque la participación de las mujeres en la manipulación y transformación de materiales es bastante antigua, este saber femenino sólo alcanzó vasta divulgación en el siglo XIX, en función del aumento de la alfabetización, desarrollo de la industria editorial y reevaluación de la educación femenina. En este escenario Jane Marcet, inspirada en las conferencias impartidas por Humphry Davy en la Royal Institution, escribió su libro dirigido especialmente a las mujeres, pues estaba convencida que los conocimientos químicos ampliarían su horizonte intelectual y las ayudaría a encontrar en la contemplación de la naturaleza una fuente de instrucción placentera.
