Authors: Sainz Villanueva José Luis
Published: April 2024

El artículo describe los resultados de la investigación denominada "El comité vecinal, experiencia para conformar las nuevas figuras de representación social en el Distrito Federal: naturaleza, desarrollo y redefinición". El estudio se realizó en siete colonias de la zona poniente de la delegación Álvaro Obregón. Se pondera la representación ciudadana y específicamente la representación vecinal como un mecanismo que fortalece la sociedad civil y establece condiciones y espacios para una mayor inclusión en la toma de decisiones de la población respecto de actividades y asuntos que le conciernen y que son determinantes en su vida y desarrollo, por lo que se puntualiza la necesidad de generar un mayor poder político a partir de reformas en los marcos jurídicos y en la figura de representación vecinal. Así mismo, se vincula a la necesidad de generar procesos de construcción ciudadana con énfasis en una dimensión imaginaria que dé pauta a la reconfiguración de visiones, prácticas y horizontes de expectativas que operen como activador de una participación ciudadana más incluyente y autónoma con un alto compromiso con su entorno, con su ámbito local y con la sociedad.

Authors: Arancibia-Olivares Rubén Ignacio , Barriga-González Germán , Reyes-González David
Published: April 2024

El laboratorio es parte fundamental en los cursos de química debido a su capacidad de articular ambientes únicos de aprendizaje. A pesar de ello, se reportan cuestionamientos asociados a la falta de evidencia empírica que demuestren sus efectos en el aprendizaje. Con la finalidad de contribuir a esta brecha, se reporta una revisión bibliográfica enfocada en los aportes de autores afiliados a instituciones latinoamericanas respecto al aprendizaje en el laboratorio de química para nivel universitario. Se identificaron 80 artículos, los cuales destacan por ser escritos principalmente por autores brasileños (43%), mayormente en inglés (83%) y principalmente en el Journal of Chemical Education (61%). Estos documentos se caracterizan por ser innovaciones curriculares (91%) con un enfoque disciplinar y presentar intencionalidades pedagógicas y metodologías para la evaluación del aprendizaje diversas y no articuladas. Estos resultados muestran que los aportes latinoamericanos están centrados en el contenido disciplinar, lo cual da espacio a nuevas investigaciones centradas en otros aspectos del aprendizaje en el laboratorio. Finalmente, es recomendable que los investigadores puedan especificar en sus publicaciones aspectos como los objetivos de sus propuestas de laboratorio, las bases teóricas con las cuales se establece el aprendizaje y los instrumentos empleados para su medición.

Published: April 2024

Se relata una experiencia sobre Cambio Climático (CC), realizada en el Máster de Profesorado de Ciencias en Formación Inicial de una universidad española. Se reproducen los experimentos de Eunice Newton Foote (1856), precursora de la ciencia climática, y se muestra su importancia crucial para la Historia de la Ciencia. La secuencia didáctica sigue un Ciclo de Aprendizaje de Karplus que busca la metacognición y la autorregulación de los aprendizajes, se contextualiza en la crisis ambiental actual, de origen antropogénico, recogida en informes internacionales. La experiencia de Foote se actualiza al siglo XXI, respecto al marco teórico y a la utilización de tecnologías electrónicas e informáticas. Los resultados muestran satisfacción del alumnado, en relación con el trabajo realizado, los conocimientos adquiridos y también reflexión metacognitiva y mejoras en sus aprendizajes, pero evidencian carencias en su formación inicial, que dificultan su interpretación de los hechos experimentales y el diseño de actividades de aula que impliquen aprendizajes significativos.
Implementación de una secuencia didáctica a distancia para cuantificación de almidón en alimentos por espectrofotometría
Authors: Hernández Valdepeña Miguel Ángel , Sandoval Guillén Bertha Julieta , Bermúdez García Eva
Published: April 2024

Las asignaturas experimentales en Química permiten a los estudiantes consolidar y aplicar conceptos teóricos mientras desarrollan competencias y habilidades básicas para su formación, como el uso de equipo e instrumental y la capacidad para resolver problemas. Ante la posibilidad de que ocurran situaciones que limiten la ejecución de prácticas de laboratorio de manera presencial, es importante contar con herramientas docentes para llevar a cabo sesiones experimentales en casa. En este trabajo se analiza la implementación de una secuencia didáctica experimental a distancia que se aplicó a estudiantes del Laboratorio de Alimentos I, en la que, con fundamento en técnicas iodométricas, se cuantifica el contenido de almidón en alimentos; obteniendo una curva patrón y utilizando una aplicación de teléfono móvil como espectrofotómetro. Al implementar la secuencia se observó una mejora significativa en la adquisición de conocimientos de los estudiantes al comparar las calificaciones de evaluaciones parciales con las de semestres previos en los que las actividades a distancia fueron sólo teóricas. Por lo que se propone que la secuencia desarrollada es una herramienta útil en contextos de enseñanza a distancia, que cumple con sus objetivos de aprendizaje y permite el desarrollo de las competencias buscadas.

Authors:   Universidad del Zulia, Carrillo Palma Julio M.
Published: April 2024

Los intercambiadores de calor de placas soldadas son equipos fundamentales para los procesos de esterilización en la industria farmacéutica, por lo que es crucial diseñar planes de mantenimiento eficaces para evitar fallos que puedan comprometer la confiabilidad de estos procesos. El objetivo de esta investigación fue determinar, mediante la simulación de Montecarlo, una política óptima de mantenimiento para estos intercambiadores. Se utilizó una metodología descriptiva, aplicada y transversal basada en un diseño de campo. Se estudiaron siete intercambiadores de calor en una planta farmacéutica, sirviendo como población y muestra. Los instrumentos de recolección de datos incluyeron la revisión de registros existentes y la validación por expertos. El estudio demostró que la distribución Weibull es una herramienta útil para modelar los tiempos de falla de los intercambiadores y reveló que el tiempo óptimo de reemplazo es de aproximadamente 1,7 años, con un costo mínimo asociado de US$2.139. Estos hallazgos resultan esenciales para la planificación eficaz del mantenimiento y reemplazo de los equipos, así como para la optimización de los recursos económicos. Sin embargo, se reconoce la necesidad de una muestra más grande y de más datos para reforzar estas conclusiones.

Authors: Kanemoto Ngomoyogoli Judith Emery , Ella Fils Armand , Kanemoto Stanley Olivier , Boudjeko Thaddée , Ngondi Judith Laure , Njintang Yanou Nicolas
Published: April 2024

The hot-water extraction method has been employed to enhance the diffusion rate of heteroglycans, thereby augmenting the extraction efficiency. This study investigates the antioxidant activities and immunological properties of water-soluble polysaccharides derived from the Hibiscus sabdariffa calyx (HWPF and LWPF). These polysaccharides were isolated through two distinct extraction methods involving hot water followed by ethanol precipitation. The physicochemical characterization was conducted through a series of experiments encompassing monosaccharide composition, ultraviolet-visible spectrum analysis, and Fourier-transform infrared (FT-IR) spectroscopy. The evaluation of antioxidative properties employed various techniques, including DPPH and ABTS radical scavenging activities, Ferric Reducing Antioxidant Power, ferrous chelating power, total reducing power, and protection against DNA damage. The assessment of anti-inflammatory potential involved the inhibition of hemolytic activity induced by a hypotonic solution and heat. Furthermore, the impact of the polysaccharides on the production of pro-inflammatory cytokines was analyzed through Luminex assay and RTPCR assay in PBMCs and LPS-stimulated RAW 264.7 cells, respectively. The findings revealed that heteroglycans (LWPF and HWPF) exhibit a content of Ara-Man-Rha-GluA-GalA (41.2:17.2:15.7:9.2:8.8) and Ara-Glu-Rha-Xyl-GluA-Man (31.5:23.8:12.16:10.4:7:6) with molecular weights of approximately 4.5 KDa and 41.3 KDa, respectively. HWPF demonstrated robust metal chelating and scavenging activities. Additionally, each fraction exhibited substantial protection of DNA against damage induced by H2O2. LWPF was observed to significantly down-regulate the expression of pro-inflammatory cytokines IL-6 and COX-2 at both transcriptional and translational levels, along with inhibiting NO production. In summary, these results indicate that the choice of extraction methods influences both the structure and biological activities of heteroglycans, providing valuable insights into the structure-activity relationship.

Robust DOA estimation for nested arrays in unknown mutual coupling
Authors: He Shun , Li Xue , Sun Bing
Published: April 2024

Aiming at solving the problem that the capability of direction of
arrival (DOA) method for estimation of nested arrays decreases sharply
under unknown mutual coupling, an iterative weighted low rank matrix
reconstruction (IW-LRMR) algorithm is proposed in this paper. Firstly,
the received data covariance matrix is extended, and a weighted low-rank
matrix recovery problem is formulated for joint estimations of the
Toeplitz matrix and mutual coupling coefficients. Next, the DOA from
recovered Toeplitz matrix is retrieved by using the root multiple signal
classification (Root-MUSIC) algorithm. Experimental results show that
IW-LRMR algorithm can effectively avoid the influence of mutual coupling
while solving the grid mismatch problem so that the accuracy and the
resolution of estimation are improved.
Topographic Roughness as an Emergent Property of Geomorphic Processes and Events
Authors: Doane Tyler H , Gearon James , Martin Harrison K , Yanites Brian J , Edmonds Douglas Arthur
Published: April 2024

Topographic roughness is a popular yet ambiguous metric used in surface
process research for many applications that indicates something about
the variation of topography over specified measurement intervals. In
soil- and sediment-mantled settings topographic roughness may be framed
as a competition between roughening and smoothing processes. In many
cases, roughening processes may be specific eco-geo-hydromorphic events
like shrub deaths, tree uprooting, river avulsions, or impact craters.
The smoothing processes are all geomorphic processes that operate at
smaller scales and tend to drive a diffusive evolution of the surface.
In this article, we present a generalized theory that explains
topographic roughness as an emergent property of geomorphic systems
(semi-arid plains, forests, alluvial fans, heavily bombarded surfaces)
that are periodically shocked by an addition of roughness which
subsequently decays due to the action of all small scale, creep-like
processes. We demonstrate theory for the examples listed above, but also
illustrate that there is a continuum of topographic forms that the
roughening process may take on so that the theory is broadly applicable.
Furthermore, we demonstrate how our theory applies to any geomorphic
feature that can be described as a pit or mound, pit-mound couplet, or
mound-pit-mound complex.
Le respect des delais de paiement : Ancrage a deployer pour soutenir les PME marocaines
Authors:   Université Chouaib Doukkali, El Jadida, Maroc, Soualih Yassine
Published: April 2024

This study aims to assess the impact of longer payment terms on the survival of Moroccan SMEs. The data collected and processed by Bank Al-Maghrib and the Observatory of payment delays in Morocco, converge towards the same unique observation, that Moroccan VSEs are the first victims of payment delays, with customer delays exceeding 8 months in 2021. This study highlights the challenges faced by these companies, and explores the legislative measures that could improve their situation. Using a methodological approach based on narrative synthesis and the analysis of quantitative data, the study highlights the positive impact of respecting payment deadlines on the growth and sustainability of Moroccan SMEs. According to a survey conducted by the World Bank, late payment is the cause of 35% of business failures in Morocco. A strong correlation is becoming evident between payment delays and business failures, with nearly 40% of failures caused by late payment. Since 2010, late payments have been the leading cause of business failure.
Becoming known: Practicing equine rescue and rehabilitation as a response-able ethic of interspecies care
Authors: Franklin Alex , Schuurman Nora
Published: April 2024

In this paper we discuss the intertwining of care with learning to know and become with the other in interspecies relationships. Drawing on interviews at horse rescue yards (England), we ask: How does an animal come to be known? What does it mean to care with an animal well? How does animal agency shape the practicing of response-able care? Caring well for a rescue horse is centred upon establishing an intimate knowledge of horses as individuals and as agents of their own life. Often the life history of an individual animal is not known and it is up to the human to imagine a possible past and present for them by interacting with the animal. Central to this process is how the agencies of both human and horse shape the emerging relational embodied interaction. Weaving together scholarship on care, agency, and interspecies relationality, we explore how the situated and intertwined processes of getting to know the other and caring well unfold. Our main assertion is that the relational knowledge which underpins the practicing of a response-able ethic of interspecies care is itself dependent on the ability of both animal and human to actively enter into a mutual (ongoing) process of learning to know and become know-able by the other. By its very (relational) nature, therefore, practicing a response-able ethic of interspecies care is simultaneously situational, dynamic, intimate and unstable. It is beyond the control of either individual alone, yet ultimately not always determinable by mutual consent of either.
Определение массы и размера нейтрона с помощью волнового уравнения Шрёдингера. Взаимодействие нейтронов в нейтронной звезде.
Authors: Чернов Андрей
Published: April 2024

В основу этого исследования было положено утверждение о существовании волны у нейтрона, когда он находится в состоянии покоя. В условиях очень плотного сближения нейтронов в нейтронных звёздах происходит обмен волнами между нейтронами. Это приводит к очень слабому взаимодействию между нейтронами. Для проверки этого утверждения в исследовании были применены два известных решения уравнения Шрёдингера: решение волнового уравнения Шрёдингера для атома водорода и решение уравнения Шрёдингера для энергии частицы в бесконечно глубокой одномерной потенциальной яме.
В результате произведённых физико-математических расчётов была определена масса нейтрона в нейтронной звезде 1,630740013 ∙〖10〗^(-27)кг и определен размер нейтрона 9,58375276 ⋅〖 10〗^(-16) м. Оба значения с высокой точностью совпали с экспериментальными данными относительно нейтрона. Небольшое отличие по массе со свободным нейтроном 2,6% можно объяснить дефектом массы нейтронов в результате гравитационного сжатия в нейтронной звезде. (В ядрах атомов химических элементов масса нейтронов также меньше массы свободного нейтрона в среднем на 0,8%). Масса нейтрона была получена через формулу, базирующуюся на трёх фундаментальных константах без применения дополнительных коэффициентов
В этом исследовании была определена величина энергии слабого взаимодействия между двумя нейтронами в нейтронных звездах: E_bind=-4,82451403 ⋅〖10〗^(-15)Эв
Были получены другие результаты, имеющие научное значение.
The Institution of the Prefecture in Romania (1864–1892): Between social relations of patronage and political networks
Authors: PLOSCARU Cristian
Published: April 2024

Historical research on the institution of the prefecture in Romania (United Principalities) in the 19th century, as a fundamental institution of modern state administration, involves several levels of analysis, combining institutional, political and social history. Our paper will focus on several aspects, in relation to a number of historical features specific to the Romanian case. These features stem from the implementation of a Western-origin institutional model in Romania, after the union of the Principalities of Moldavia and Wallachia, until the end of the 19th century. During this period, a maturation of the modern administration can be observed, both legislatively and functionally. In addition to the legislative framework of this period (the communal law of April 1864, amended in March 1872 and March 1883, the law on county councils of April 1864 and the law on the organization of administrative authorities of November 1892), other factors are also noteworthy, which made the prefect in Romania not only a government agent at the local level, but also a county administrator: the patronage relations of the Romanian elite – a legacy of the Old Regime, and the gradual consolidation of the power networks of the governing political parties, both of which had a relevant impact on the selection process of local officials and the conduct of parliamentary elections.
Rezumat: Cercetarea istorică a instituţiei prefecturii în România (Principatele Unite) în secolul al XIX-lea, ca instituţie fundamentală a administraţiei de stat moderne, implică mai multe niveluri de analiză, combinând istoria instituţională cu istoria politică şi socială. Ne vom concentra asupra câtorva aspecte, în legătură cu unele trăsături istorice specifice cazului românesc, rezultate din aplicarea unui model instituţional de origine occidentală în România, după unirea Principatelor Moldovei şi Valahiei, până la sfârşitul secolului al XIX-lea, când se poate observa o maturizare a administraţiei moderne, atât din punct de vedere legislativ, cât şi funcţional. Pe lângă cadrul legislativ al acestei perioade (legea comunală din aprilie 1864, modificată în martie 1872 şi martie 1883, legea consiliilor judeţene din aprilie 1864 şi legea de organizare a autorităţilor administrative din noiembrie 1892), se remarcă şi alţi factori care au făcut ca prefectul să fie în România nu doar un agent guvernamental la nivel local, ci şi un administrator al judeţului: relaţiile de patronaj proprii elitei româneşti, moştenire a Vechiului Regim şi consolidarea treptată a reţelelor de putere ale partidelor politice guvernamentale, ambele având un impact relevant în procesul de selecţie al funcţionarilor de la nivel local şi în desfăşurarea alegerilor parlamentare.

Digital Currencies: Is Africa Ready?
Authors: MPOFU Favourate Y.
Published: April 2024

Digital currencies are likely to modify the way businesses, people and governments transact in Africa. Nonetheless, several factors need to be assessed before the wide adoption of digital currencies in the continent. These factors include the regulatory environment for fintech, the condition of digital infrastructure and the degree of financial inclusion. This paper assesses the readiness of African countries for the issuance of digital currencies. The paper gives an overview of the African countries that have implemented or are considering implementing digital countries. It discusses the issues to be considered for a conducive environment to launch digital currencies. It explores the opportunities and challenges of developing and issuing digital currencies in Africa. The paper finds that although the developed mobile money network infrastructure, high mobile money penetration, the growth of the digital economy and high degrees of financial exclusion position Africa well for the adoption of central bank digital currencies (CBDCs), several challenges need to be addressed. These encompass lower levels of financial inclusion, digital exclusion, the digital divide, poor digital infrastructure and regulatory uncertainty. The paper provides recommendations for improving the prospects of digital currencies in Africa. These include the creation of a legal and regulatory framework for digital currencies, investing in digital infrastructure, improving internet connectivity and educating citizens on digital currencies. Digital currencies can lead to improved economic growth, increase cross border payments, promote financial inclusion and sustainable development.

Rotor Flux and EEMF Observer for Interior Permanent Magnet Synchronous Machine
Authors: Vyas Deepak , Morawiec Marcin , Wachowiak Daniel
Published: April 2024

In recent years, the use of the Interior Permanent Magnet Synchronous Machine (IPMSM) in various applications has grown significantly due to numerous benefits. Sensors are used to achieve high efficiency and good dynamic response in IPMSM drives but due to their high cost and reduce overall size of system,sensorless control techniques are preferred. Non-sinusoidal distribution of rotor flux and slot harmonics are present in the considered IPMSM. In this article, these problems are considered as control system disturbances. With the above-mentioned problems, the classical observer structure based on (d-q) fails to estimate at low-speed ranges. This article proposes an observer structure based on a rotor flux vector in (α-β) stationary reference frame, which works using the adaptive control law to estimate speed and position, and a non-adaptive EEMF-based observer to estimate speed and position. Moreover, a comparative analysis between both observer structures at the different speed ranges is also considered in this article. The effectiveness of the observer structure is validated by simulation tests and experimental tests using the sensorless control system with a field-oriented control scheme for 3.5 kW IPMSM drive system.

Comprehensive metabolic diagnostics is a is a prerequisite for preventing the progression of the disease. However, the care situation in the diagnosis of MASH is characterised by a number of characterised by a number of limitations, including the limited use of the of the screening algorithm and the challenges involved in making a definitive diagnosis by means of liver biopsy. The discrepancy between the diagnosed number of MASH cases diagnosed and the presumed prevalence indicates a significant significant number of undiagnosed cases, which ultimately also leads to therapeutic deficit
Prospects for the development of the EAEU amid a confrontation between Russia and the West
Authors: Ovcharenko D. V.
Published: April 2024

The article examines the consequences of the Western states’ sanctions pressure on Russia for the EAEU. Special attention is paid to the position of the EAEU members amid two crucial events in the Ukrainian crisis: the reunification of Crimea with Russia (2014) and the beginning of a special military operation (SMO) in Ukraine (2022). Measures aimed at minimizing the damage from anti-Russian sanctions on the economies of the EAEU countries are considered, such as: customs, customs tariff and non-tariff regulation, protective measures; internal market and cooperation; financial and currency markets; international economic cooperation with third countries and integration associations. The priorities of Russia’s chairmanship in the EAEU in 2023 are analyzed. The prerequisites for the further development of the EAEU as a self-sufficient integration center in Eurasia and the prospects of the EAEU amid a confrontation between Russia and the West are examined. Among the negative factors slowing down the development of the EAEU the following stand out: the orientation of some members to the third countries’ markets, the modest pace of modernization and increasing the competitiveness of the economies of the EAEU countries, the insufficient level of development of transport infrastructure and logistics, the concerns of the EAEU members (Armenia, Kazakhstan, Kyrgyzstan) of «secondary» sanctions, the absence of a consolidated position within the union regarding Western sanctions, the violation of transactional payments as an outcome of Russia’s disconnection from international payment systems.

In this work, inspired by the structure of spider web, the water-resistant sticky polypropylene (PP) net was fabricated for capturing mosquitoes here. The waterresistant pre-glue was first obtained through mixing liquid polydimethylsiloxane (PDMS), solid polytetrafluoroethylene (PTFE) microparticles and tetraethyl silicate (TEOS), where TEOS was used as cross linker to enhance adhesion strength. The sticky mosquitoes PP net was obtained through heating the PP net painted with the water-resistant pre-glue uniformly on the two sides of PP net at 60°C for 2 days. This sticky mosquitoes PP net works well in sticking mosquitoes even in the humid air.

Background: Primary intraparenchymal meningiomas are extremely rare; their similarities to other intra-axial lesionsand thelack of dural adhesion make their presurgical diagnostic approach challenging. Case Description: A 27-year-old male, with no past medical history, presented to our emergency department for a first time grand mal seizure. Magnetic resonance imaging evidenced a 1,6×1,2 cm mass in the right temporo-parietal region. It was iso intense on T1WI, hyper intense on T2 WI, surrounded by large vasogenic edema and homogeneously enhanced on contrast magnetic resonance imaging with diffusion restriction. During surgery, the tumor was found to be located within the parenchyma with no dural attachment. It was removed en bloc. Histopathological examination confirmed the positive diagnosis of transitional meningioma (WHO Grade I). Conclusion: Intraparenchymal meningiomas are rarely reported in the literature. Their preoperative diagnosis is extremely difficult to make. Histopathological examination plays a key role for an accurate diagnosis.

Solitary Fibrous Tumor of the Pleura (SFTP) is an exceptionally rare mesenchymal tumor that typically originates from the visceral pleura and constitutes less than 5% of all pleural tumors. While it often displays benign histological features, the tumor’s behavior remains enigmatic and less comprehensively understood, primarily owing to its limited incidence and case studies. We present two cases of SFTP. The First one was a small pleural nodule a nodule in a 61 year old patien, confirmed as a SFTP through CT-guided biopsy. Successful tumor resection was performed, with histopathological confirmation, and the patient remained recurrence-free for two years. The second one was incidental finding in a 68-year-old patient of a huge pleural mass with necrotic regions and microcalcifications on imaging. Surgical removal revealed an encapsulated tumor with myxoid features, classified as an intermediate-risk SFTP. The patient experienced no complications and had no local recurrence 16 months post-surgery. Solitary fibrous tumors within the pleura are uncommon. The preferred treatment approach is surgical resection, with diligent post-operative monitoring.

Microbiological contamination of drinking water is still a major issue in developing and under developing countries. Until it was safe to drink, water was typically stored in a variety of metal pots. Copper was discovered to be far more effective than the other metals. Ayurveda also recommends copper pots for drinking water. Therefore, the goal of this research is to see how copper affects numerous multi drug-resistant Escherichia coli clinical isolates. A total of 40 multi drug-resistant Escherichia coli were identified from various clinical specimens. For different periods of time, deionized water was put on a household copper pot having a capacity of 2 liters and a surface area of 860cm2 (2, 6, 12, 18, and 24 hours). Atomic absorption spectroscopy was used to measure the amount of copper leached. Luria Bertani broth was prepared using water stored in copper pot at different time interval. Diluted bacterial suspension was spreaded on Mac-Conkey agar plate surface for viable count. Copper leached from 24hour storage water was found to successfully suppress bacterial growth within the safety limit, followed by shorter time intervals. To combat multidrug-resistant Escherichia coli, this study recommends drinking water from a copper pot.

Bacteria promoting cancer development and tumor progression are gramnegative bacteria like Salmonella’s species and can play key role in the therapy of cancer. As tumor site are oxygenated so it when systematically gramnegative bacteria rushed into the tumor site, then their necrotic region produced by the reduction of oxygen and declination of nutrients. In the patients of lung cancer, NSCLC mostly, diagnosing the persons which suffer with NSCLC showed that in advanced stage gram negative bacteria play major role in the infection of patients with (NSCLC). In NSCLC patients’ infection of lungs along with gram negative bacteria are usually issues after having surgical operation. Assembling proof specify a participation of gram-negative bacteria within the non-small cell lung cancer succession, fundamental processes endure unrevealed. This article would explain the consequence of GN bacteria on the progression of tumor tissues of NSCLC victims. After observance it is concluded that the process of infecting by gram negative bacteria predicted in preliminary stages. The increment and metastasis of non-small cell lung cells caused by incubation by NSCLC with Gram negative bacteria. The mechanism explored that Gram negative bacteria operated tall-like receptor no, 4 which signaling to NSCLC cells, which caused to increase the production of messenger-RNA and expression of protein of interleukin 33 by MyD88-passageway. The destruction of IL-33 revokes the participation of gram-negative bacteria to non-small cell lung cancer succession by controlling cancer metabolic occupation. The increment of IL-33 expression, CD133 expression was directly proportional to TLR4 expression. This information explains the molecular technique of gramnegative bacteria moderate tumor succession.

Katishoola is the term used in ayurvedic texts which resembles low back pain. The term ‘Kati’ used for lower back arises from the oldest language of human civilization, Sanskrit (4000–5000 BC). In an ancient text, Amarkosha ‘Kati’ has been related to the area of ‘Sroni’ or hip bone. Shoola (Ruja, Vyatha, Yama, or Ruk) is pain or discomfort. The earliest evidence of back pain outside the Indian subcontinent comes from an ancient Egyptian surgical text called Edwin Smith papyrus (named after Edwin Smith, who bought it in 1862. Sciatica pain is a direct result of pressure on sciatic nerve or sciatic nerve root pathology. The sciatic nerve is made up of the L4 through S2 nerve roots, which coalesce at the pelvis to form the sciatic nerve. About 2cm in diameter, the sciatic nerve is easily the largest nerve in the body. Sciatica pain often is worsened with twisting, bending, or coughing. In India most practicing doctors across all systems usually determine the cause of Sciatica pain by asking a few questions and a thorough physical examination. Imaging is initially of little value. An MRI or a non-contrast CT scan may be performed to evaluate fracture if plain films are negative. Management of Sciatica traditionally revolves around reducing pain and inflammation, strengthening supportive muscles in lower back, hips, and thighs. Laminectomy or Discectomy are attempted if the surgery is needed to relieve the pressure on the nerve. Of late a New German technology powered based on regenerating new tissue becoming popular. This article reviews about 5 patients and 6 episodes of Sciatica. Four episodes were common and two un-common conditions, of which only needed laminectomy. Their management by different systems of medical practice are described and review of the literature across the systems adds to the epidemiology, causes and management of Sciatica in India. Materials & Methods: Four cases, one of them suffering twice after an interval of a decade and traditional management of these cases by allopathic, Unani system, Homeopathy and Yoga exercises, for the core content of sciatica management in Primary and secondary settings. Brief notes on two cases needing surgery and the first-hand information on latest QI based neuromodulation approach update complete the options currently available in India.
