Published: December 2020

Pendidikan merupakan suatu hal yang harus diprioritaskan dalam kehidupan manusia. Sebab dunia tanpa pendidikan adalah dunia tanpa arti. Kehidupan manusia tidak mengacu pada pendidikan maka akan senantiasa dalam alam kebodohan. Dalam artian memisahkan manusia pada pendidikan sama artinya memisahkan manusia pada kehidupan yang sejati. Eksistensi penciptaan manusia bersama dengan kewajiban untuk berpendidikan. Kewajiban berpendidikan sama artinya kewajiban dalam beribadah. Pahala membaca sama artinya pahala beribadah, karena beribadah tanpa dasar ilmu pengetahuan akan berujung kepada kesia-siaan.
Awal dari kehancuran dunia Pendidikan karena krisis disiplin. Negara barat salah satu penyebab kemajuan mereka yakni dengan menumbuhkan kesadaran untuk disiplin. Dalam hal ini perlu juga ditanya mengapa pada dasarnya manusia harus disiplin? Kedisiplinan pada dasarnya berguna bagi manusia itu sendiri. Dan bila manusia tidak displin maka akan berakibat tidak baik bagi dirinya. Misalnya disiplin lalu lintas, lampu merah yang ada dijalan raya, bukan penghambat pengemudi, namun pada dasarnya untuk memberikan keamanan bagi pengemudi itu sendiri. Coba bila lampu merah itu dilanggar, maka berakibat akan terjadinya kecelakaan.
Jadi meningkatnya kedisiplinan sangatlah penting, Negara Jepang, Cina dan Amerika, dalam dunia pendidikan mereka sangat maju, dan salah satu rahasia mereka adalah disiplin. Kegiatan belajar dan mengajar (KBM) tidak akan efektif dan maksimal bila tingkat disiplin masih belum diperhatikan. Bahkan Negara Indonesia juga tidak akan pernah maju dan berkembang kalau tidak disiplin. Jangan sampai kehancuran pendidikan Negara Indonesia ini karena menganggap remeh arti disiplin. Meningkatkan kedisiplinan merupakan kunci untuk kemajuan. Dan krisis disiplin haruslah kita akhiri mulai detik ini. Bila ingin Negara kita ini dapat mengejar ketertinggalan dari Negara maju lainnya terutama dalam bidang pendidikan. Marilah kita hidupkan disiplin dalam kehidupan kita.

Published: December 2020

El frijol es un cultivo estratégico para México, representa una importante fuente de ocupación e ingreso en la economía campesina y en la dieta, representa la única y principal fuente de proteínas, para amplias sectores de la población, además es un alimento con importantes propiedades nutracéuticas. En el sur de Veracruz, se obtienen rendimientos promedio de 700 kilogramos por hectárea, esta baja productividad obedece principalmente al uso de materiales criollos regionales de limitada capacidad productiva y susceptible a enfermedades y un manejo inadecuado del cultivo, por lo que el objetivo de este estudio fue determinar el potencia de rendimiento de cuatro genotipos de frijol (Phaseolus vulgaris L.), su respuesta a la fertilización mineral y al uso de biofertilizantes, en el municipio de Catemaco, Veracruz. Los rendimientos de grano ha-1 indican que no hubo diferencia entre genotipos, con rendimientos promedio de casi 2 t ha-1, casi el triple de los promedios de la región. El uso de la fórmula 40-40-40, casi duplica el rendimiento del testigo absoluto, el uso de biofertilizantes también incrementó el rendimiento y la interacción de primer orden entre genotipos y fertilización mineral, resulto significativa estadísticamente.

Authors: Camacho Castro Alberto Jorge 
Published: December 2020

ANTECEDENTES: Los ganglioneuromas son tumores excepcionales. Hasta el momento no existe un consenso de tratamiento, por lo que es necesario individualizar cada caso. CASO CLÍNICO: Paciente masculino de 36 años, con afectación intermitente de la fosa renal izquierda y el flanco ipsilateral de cuatro meses de evolución. El ultrasonido abdominal reportó una masa adyacente al riñón izquierdo, en su porción superior, de 5 x 4 cm, hipoecoica, sin calcificaciones. La tomografía abdominopélvica simple y contrastada evidenció una neoplasia suprarrenal izquierda, de 8 x 5 cm. Se programó para adrenalectomía laparoscópica izquierda. Durante el procedimiento se encontró una neoplasia suprarrenal de 9 x 8 cm, firmemente adherida a la vena renal ipsilateral, por lo que solo se practicó la resección parcial del tumor. La evolución del paciente fue satisfactoria y egresó al segundo día posoperatorio. El reporte de patología evidenció dos fragmentos de tejido, que en conjunto pesaron 55 g, y por separado 5.5 x 4.2 cm y 4.5 x 2.8 cm, respectivamente. La histología mostró un estroma constituido por células de Schwann, orientadas en dirección longitudinal y transversal, entrecruzadas en forma irregular. De acuerdo con los hallazgos histopatológicos y el estudio de inmunohistoquímica se estableció el diagnóstico de ganglioneuroma suprarrenal. CONCLUSIONES: Los ganglioneuromas suelen provocar síntomas inespecíficos, por lo que el diagnóstico se establece de forma fortuita. Después de la resección del tumor, el pronóstico de los pacientes es excelente. Este es el primer caso de ganglioneuroma reportado en México. PALABRAS CLAVE: Ganglioneuroma; neoplasia suprarrenal; adrenalectomía laparoscópica.
Reflexões sobre o conceito de Autonomia para o Ensino de Ciências: elementos da filosofia de Cornelius Castoriadis como fundamento para a crítica da pós-verdade
Authors: Monteiro Midiã Medeiros , Silva Márcia Gorette Lima da 
Published: December 2020

Um importante aspecto que diz respeito ao Ensino de Ciências (EC) e que acreditamos permanecer com lacunas a serem preenchidas diz respeito ao seu objetivo. Este artigo tem como foco discutir a autonomia como um objetivo para o EC, esta pensada à luz da perspectiva filosófica de Cornelius Castoriadis. Em concreto, nos propomos reflexões em três direções, inicialmente interrogar a concepção de formação humana e o objetivo do EC apontando a autonomia como um sentido para pensar esta formação; em seguida, apresentar a perspectiva filosófica de Cornelius Castoriadis e o seu Projeto de Autonomia, considerando sobretudo os conceitos de imaginário, imaginação e instituições sociais, sustentando que a criticidade figura como um de seus elementos constitutivos e; por fim, defender a ideia de que essa perspectiva pode contribuir para a reflexão sobre o EC na superação da ideia de pós-verdade. É na análise crítica das afirmações de conhecimento que situamos a autonomia, podendo parecer paradoxal pensá-la em oposição a pós-verdade quando se concebe nela uma possível relativização da verdade, mas que enseja uma crítica a verdade.

Introduction and Aim: Iron deficiency anemia is the commonest cause of anemia in developing country like India in all age groups. It is most easy to prevent as well as to treat. Its diagnosis and treatment are based on serum ferritin levels in developed countries which is not possible in India at primary healthcare setting. This study was undertaken to explore if red cell indices could replace serum ferritin in detecting iron deficiency.
Materials and Methods: Study of association of red cell indices like Mean Corpuscular Volume (MCV), Mean Corpuscular hemoglobin (MCH), Mean Corpuscular hemoglobin Concentration (MCHC), Red cell Distribution Width (RDW) and Hemoglobin concentration (Hb%) with iron deficiency anemia and the correlation of these Red cell indices and Hb% with serum ferritin was done in 220 anemia patients of all age groups with Hb% <12g/dL.
Results: Descriptive data showed skewed distribution of serum ferritin. Statistically significant reduction in all red cell indices values among iron deficiency anemia patients and statistically significant correlation of all red cell indices values except red cell distribution width with serum ferritin was found.
Conclusion: Unlike developed countries we can use simple estimation of hemoglobin concentration along with red cell indices for diagnosing iron deficiency anemia in primary healthcare setting of India.

Published: December 2020

Introduction and Aim: Adequate birth spacing has proved to be an important factor in reducing both Maternal and Childhood mortality and morbidity. According to NFHS 4 data currently in India only 2/3rd of the births are having spacing of more than 2 years. Therefore this study was planned to find out the awareness and practice of birth spacing among Married women residing in asemiurban area near Chennai.
Methods: Cross-sectional study was conducted among 115 married women of Reproductive age group. Pretested and predesigned semi structured Questionnaire was used to collect data on Awareness and practice regarding birth spacing. Data was analysed using proportions.
Results: 96.5% women considered birth spacing as a good practice, 71.3% women had knowledge regarding birth spacing methods. 31.6% women practiced spacing after their first child. IUCDs was the most preferred method adopted. Lack of awareness regarding contraceptives followed by fear of complications was the major reason for not adopting spacing methods.
Conclusion: Attitude regarding spacing was found to be good but knowledge and practice were less. It is high time that New contraceptives like injectable DMPA, POP and Centchroman be introduced in all the health facilities and people should be made aware of all the available methods.

Introduction and Aim: Rapid prototyping is an advanced fabricating method, where three dimensional objects are built precisely from their three-dimensional computer aided design models in a very short duration. In contrast to traditional machining methods, most of the rapid prototyping techniques tend to fabricate parts based on additive manufacturing process. Fabrication of biomaterial into 3-D scaffold structures is the next vital step in the development of bone implants depending on bone injuries of individual patients, and it is highly demanding among the Indian orthopedic surgeons for treating those bone related defects. Therefore, the need for reliable and economically feasible design, better biomaterials, and efficient fabrication method for scaffold to treat musculoskeletal defects has increased in recent years.
Materials and Methods: Investigation of scaffold for porous structured bone implant is a recently emerging field in medicine and is involved in developing artificial bones like structure using materials like Tri Calcium Phosphate (TCP), Polyether ether ketone (PEEK), Hydroxyapatite (HA), Polycaprolactone, polycarbonate (PC), poly (l-lactide) PLLA or Polyamide (PA) etc., by incorporating pores in the scaffold. In this research, the samples of the scaffold specimens were designed and fabricated using Stereo lithography technique with biocompatible PC resin and the strength of each sample were analyzed.
Results: The porous scaffold models are structured with different designs utilizing the CAD software. The porous scaffold with various porosity and pore shape is analyzed through Finite Element Analysis (FEA). StereolithographyViperSi2 method was utilized to manufacture the polycarbonate scaffold. The manufactured rhombus pore model shows the stress value esteems around 200 MPa¸ which is nearest to the compressive strength of human bone. Subsequently the rhombus pore model gives better mechanical load bearing capacity when implanted for tissue recovery in bones.
Conclusion: Bisphenol-A Polycarbonate material give better surface completion, 100% pore interconnectivity and new tissue arrangement of the fabricated porous scaffold. The SLA technique offers the more noteworthy load bearing quality and great exactness of the fabricated scaffold.

Introduction and Aim: Cigarette smoking, one of the fundamental roots of preventable morbidity, has a myriad of notorious effects. Nicotine is the most bountiful and symbolic constituent of cigarette smoke. The liaison between smoking and infertility has been investigated for decades; but it’s still dubious whether the noxious effects of cigarette smoking on testis and sperm characteristics are by virtue of nicotine. Therefore, the current study interrogated the ameliorative effects of folic acid and vitamin B12 on nicotine induced catastrophe in testicular tissue and sperm characters in male albino rats.
Materials and Methods: Rats were treated with nicotine (3 mg/kg body weight/day, intraperitoneal) with or without folic acid (36µg/kg body weight/day, orally) and vitamin B12 (0.63µg/kg body weight/ day, orally) for 21 days. Sperm qualities were analyzed for motility and morphology. Various oxidative and anti- oxidative stress parameters, pro inflammatory cytokines levels, hormonal assays were performed.
Results: Findings marked that nicotine caused degenerative changes in the testicular tissue. Supplementation with folic acid and vitamin B12 reversed these results along with suppressing the nicotine induced changes in TNF- ?, IL-6, and markers of oxidative stress. Moreover, folic acid and vitamin B12 in combination also significantly blunted the altered activities of testicular key androgenic enzymes, plasma levels of testosterone, LH, and FSH following nicotine exposure.
Conclusion: In closure, testimonies manifested that folic acid and vitamin B12 may act as plausible strategy against oxidative stress, which is a pivotal step in nicotine-induced reproductive toxicity, and bettering functional status of testicular tissue by scavenging free radicals and hindering the generation of pro- inflammatory cytokines.
