Efecto del valor agregado del consumo cultural: una aproximación a la economía naranja en Colombia
Authors: Jiménez Iván Felipe , Millán María Fernanda , Suárez Diego Felipe
Published: September 2020

La economía naranja es definida como el conjunto de actividades que de manera encadenada permiten que las ideas se transformen en bienes y servicios creativos, cuyo valor está determinado por su contenido de propiedad intelectual. El valor estimado de esta economía es de alrededor de 4,3 billones de dólares. La determinación de su valor en Colombia es el objetivo de esta investigación; aun así, se hace un cálculo aproximado dada la complejidad de su valoración. Para ello se escogieron un grupo de nueve de actividades de consumo cultural durante un periodo de 10 años; artes visuales, artes escénicas, educación cultural, creación literaria, musical, teatral y audiovisual, filmes y videocintas, fabricación de juegos y juguetería, música, editorial y creación publicitaria. Se estima que en Colombia entre el 2005 y el 2014 la economía naranja, en promedio, correspondió a 0,69 % del PIB, su valor agregado sobre la producción al 53,09 %, y su grado de industrialización al 0,36 %.

Aproximación a la percepción de la economía colombiana en 2017: evidencia empírica de la comunidad estudiantil eanista
Authors: Rojas Díaz Diego Alejandro
Published: September 2020

La actualidad económica nacional es un fenómeno que concierne a los colombianos e inversionistas extranjeros. Actualmente se experimenta un momento de alta incertidumbre, a causa del panorama económico internacional, las fuertes coyunturas nacionales en materia de inversión, la duda sobre el papel ético del Estado como organismo y las tensiones en materia política por la alta migración y la crisis económica del Estado venezolano; no obstante, la perspectiva a corto plazo parece optimista, puesto que las economías emergentes siguen creciendo y actuando como aliados de la producción colombiana.

Y aunque el valor de inversión registrado por el DANE para el tercer trimestre de 2017 sobre el PIB fue del 2 %, se prevén cambios dependiendo de las decisiones que se tomen en el nuevo gobierno. En razón a estos cambios, el acercamiento hacia la apreciación colectiva sobre los mismos es lo que se procura evidenciar en esta investigación, mediante una muestra empírica destinada a conocer las opiniones de la comunidad estudiantil de la Universidad EAN.
Política vs. economía: enfoque desde la Universidad EAN
Authors: Garay Cortés Sebastián
Published: September 2020

A través de la realización de un conjunto de encuestas, practicadas por los integrantes del semillero Domus de la universidad EAN, a otros estudiantes de las distintas carreras de la institución, se pretende evidenciar la importancia de la percepción política en un país como Colombia, dando a conocer al lector la forma en la que la postura política de una población puede incidir de forma directa en el funcionamiento de su economía, esto teniendo en cuenta que existe una diferencia bastante importante entre los resultados generales de la economía colombiana con respecto a la distribución de la riqueza en el país, debido a los altos niveles de desigualdad que se observan. De esta manera, se logran identificar aspectos importantes frente a concepciones que se tienen respecto al funcionamiento político en el país y la confianza que genera el Gobierno actual.
Calidad de vida: tenderos en Bogotá
Authors: Rodríguez Cabarcas Jesús David , Acosta Mateus Nicolás , Ruiz Rivera Francisco Javier , Medellín Lancheros Laura Jahel
Published: September 2020

El siguiente artículo presenta un análisis de la calidad de la vida de los propietarios de tiendas de barrio ubicadas en las localidades de Ciudad Bolívar y Kennedy en Bogotá. Dicho análisis se realizó con base en las encuestas realizadas a tenderos de estas localidades a través del apoyo de la Secretaría de Desarrollo Económico.Según las encuestas realizadas se puede afirmar que algunas de las dimensiones de la calidad de vida laboral de la teoría de Richard Walton no se observan en la vida de la gran mayoría de los tenderos encuestados. Por ejemplo, algunas tiendas no cuentan con condiciones de trabajo saludables y seguras, y algunos tenderos tampoco con un equilibrio adecuado entre el trabajo y otros espacios de vida.
¿Hasta qué punto ser tendero se considera un trabajo digno?
Authors: Ávila Martínez Juan Camilo , Barbosa Amador Julieth Maritza , Forero Bustos Paula Daniela , Olmos Alonso Alejandra
Published: September 2020

Esta investigación inició con la idea de caracterizar uno de los empleos más comunes y proliferantes en la ciudad de Bogotá, en especial, en ciertas localidades: la labor de tendero.Para ello, se practicaron una serie de encuestas y se realizó un análisis de los datos recolectados con el cual se buscó evaluar los distintos patrones de comportamiento que desarrollan los tenderos y sus empleados en el transcurso de la ejecución de sus actividades, para de esta manera determinar qué tan digno puede considerarse el oficio de tendero.Para ello se revisaron dos factores fundamentales: el tiempo de dedicación a la labor y los ingresos o réditos que generan las tiendas. Se encontró finalmente que existe una sobrecarga laboral en los tenderos, quienes además de dedicarle más de 12 horas diarias a su labor, no toman vacaciones anuales, lo que va ligado al segundo factor, ya que los ingresos que generan las tiendas apenas cubren los gastos básicos del hogar y del local, dejando un margen nulo de dinero para otro tipo de inversiones.

Graphene oxide and thiol functionalized natural zeolite for the removal of lead from water
Authors: Manjili Mohsen , Silva Marcia R. , Garman David , Zhang Hai-Feng
Published: September 2020

Materials with potentially enhanced adsorption properties were developed by functionalizing natural clean clinoptilolite zeolite (CZ) to fabricate graphene oxide coated zeolite (GOZ) and cystamine dihydrochloride zeolite (CDHZ). The functionalized materials were characterized with Fourier transform infrared spectroscopy (FTIR), Raman, thermogravimetric analysis (TGA), and a scanning electron microscope (SEM) equipped with X-ray spectroscopy (EDS) techniques. The solution pH effect on removal efficiency was investigated at acidic, neutral, and basic pH levels. All adsorbent materials showed the highest adsorption capacities at neutral pH. Experiments were used to assess efficacy for the removal of lead with the sorption kinetics and the adsorption isotherms being determined for the baseline material CZ and treated zeolites. The addition of graphene oxide and thiol functional groups increased the lead removal capacity of natural clean zeolite by 16.81% and 34.53%, respectively. Diffusion studies revealed that the overall lead adsorption process is a particle diffusion process. Theoretical calculations confirmed the pseudo-second-order model as the kinetic mechanism for lead adsorption for CZ, GOZ and CDHZ.

Functional Role of Glycosphingolipids in Cancer
Authors: Zheng Changping , Terreni Marco , Sollogoub Matthieu , Zhang Yongmin
Published: September 2020

:

Glycosphingolipids (GSLs) are ubiquitous components on animal cell membranes, and exposed on the outer surface. Various studies have demonstrated that they play key roles in cells proliferation, adhesion, motility and differentiation.
Usually, the specific types of GSLs are expressed more highly in tumors than in normal tissues, which are known as tumorassociated antigens. It has been revealed that most tumor cells show altered GSLs patterns on their surface, abnormal GSLs
signaling and biosynthesis, which together play a major role in tumor development. Tumor-associated GSL antigens have
been used in the development of antitumor vaccines. It is no doubt that GSLs play a crucial role in tumor progression and
would be a promising target for cancer treatment.
Molecular Docking Analysis of Flavonoid Compounds with Matrix Metalloproteinase- 8 for the Identification of Potential Effective Inhibitors
Authors: Taherkhani Amir , Orangi Athena , Moradkhani Shirin , Khamverdi Zahra
Published: September 2020

Background:

Matrix metalloproteinase-8 (MMP-8) participates in the degradation of different
types of collagens in the extracellular matrix and basement membrane. Up-regulation of the
MMP-8 has been demonstrated in many disorders including cancer development, tooth caries, periodontal/
peri-implant soft and hard tissue degeneration, and acute/chronic inflammation. Therefore,
MMP-8 has become an encouraging target for therapeutic procedures for scientists. We carried out a
molecular docking approach to study the binding affinity of 29 flavonoids, as drug candidates, with
the MMP-8. Pharmacokinetic and toxicological properties of the compounds were also studied.
Moreover, it was attempted to identify the most important amino acids participating in ligand binding
based on the degree of each of the amino acids in the ligand-amino acid interaction network for
MMP-8.

Methods:

Three-dimensional structure of the protein was gained from the RCSB database (PDB ID: 4QKZ).
AutoDock version 4.0 and Cytoscape 3.7.2 were used for molecular docking and network analysis,
respectively. Notably, the inhibitor of the protein in the crystalline structure of the 4QKZ was considered
as a control test. Pharmacokinetic and toxicological features of compounds were predicted
using bioinformatics web tools. Post-docking analyses were performed using BIOVIA Discovery
Studio Visualizer version 19.1.0.18287.

Results and Discussions:

According to results, 24 of the studied compounds were considered to be
top potential inhibitors for MMP-8 based on their salient estimated free energy of binding and inhibition
constant as compared with the control test: Apigenin-7-glucoside, nicotiflorin, luteolin,
glabridin, taxifolin, apigenin, licochalcone A, quercetin, isorhamnetin, myricetin, herbacetin,
kaemferol, epicatechin, chrysin, amentoflavone, rutin, orientin, epiafzelechin, quercetin-3-
rhamnoside, formononetin, isoliquiritigenin, vitexin, catechine, and isoquercitrin. Moreover, His-
197 was found to be the most important amino acid involved in the ligand binding for the enzyme.

Conclusion:

The results of the current study could be used in the prevention and therapeutic procedures
of a number of disorders such as cancer progression and invasion, oral diseases, and
acute/chronic inflammation. Although, in vitro and in vivo tests are inevitable in the future.

Numerous treatment methodologies which have been applied to the degradation of dyes. The current study has been focused on the distinct low cost and cost-effective adsorbents used in the removal of various dye pollutants. Also, the application of nanoparticles in the removal of the hazardous dye pollutants had received great interest because of its size and high reactive nature.

Methods:

The treatment technologies used in the removal of dye pollutants from wastewater have been listed as adsorption, coagulation, electrocoagulation, flocculation, membrane filtration, oxidation and biological treatment.

Results:

The complex structure of the dyes causes a great harmful impact on the aquatic environment. Though numerous treatment technologies have been applied, adsorption has been preferred by various researchers because of its cost-effective nature.

Conclusion:

The various adsorbents are used in the removal of cationic, anionic and non-ionic dyes. The different types of adsorbent from agricultural waste, activated carbons, nanomaterials and biomaterials have been discussed with the advantages and limitations.
Current Use of Cardiac Biomarkers in Various Heart Conditions
Authors: Khan Shahzad , Rasool Sahibzada T.
Published: September 2020

Biomarkers are increasingly recognized to have significant clinical value in early identification
and progression of various cardiovascular diseases. There are many heart conditions, such
as congestive heart failure (CHF), ischemic heart diseases (IHD), and diabetic cardiomyopathy (DCM),
and cardiac remodeling, in which the severity of the cardiac pathology can be mirrored
through these cardiac biomarkers. From the emergency department (ED) evaluation of acute coronary
syndromes (ACS) or suspected acute myocardial infarction (AMI) with cardiac marker Troponin
to the diagnosis of chronic conditions like Heart Failure (HF) with natriuretic peptides, like
B-type natriuretic peptide (BNP), N-terminal pro-B- type natriuretic peptide (Nt-proBNP) and mid
regional pro-atrial natriuretic peptide (MR- proANP), their use is continuously increasing. Their
clinical importance has led to the discovery of newer biomarkers, such as the soluble source of tumorigenicity
2 (sST2), galectin-3 (Gal-3), growth differentiation factor-15 (GDF-15), and various
micro ribonucleic acids (miRNAs). Since cardiac pathophysiology involves a complex interplay between
inflammatory, genetic, neurohormonal, and biochemical levels, these biomarkers could be
enzymes, hormones, and biologic substances showing cardiac injury, stress, and malfunction.
Therefore, multi-marker approaches with different combinations of novel cardiac biomarkers, and
continual assessment of cardiac biomarkers are likely to improve cardiac risk prediction, stratification,
and overall patient wellbeing. On the other hand, these biomarkers may reflect coexisting or
isolated disease processes in different organ systems other than the cardiovascular system. Therefore,
knowledge of cardiac biomarkers is imperative. In this article, we have reviewed the role of
cardiac biomarkers and their use in the diagnosis and prognosis of various cardiovascular diseases
from different investigations conducted in recent years.

Authors: Bosgana Pinelopi , Nikou Sophia , Dimitrakopoulos Foteinos-Ioannis , Logotheti Souzana , Tzelepi Vasiliki , Kalophonos Charalambos , Bravou Vasiliki , Kourea Eleni , Sampsonas Fotios , Zolota Vassiliki
Published: September 2020

Background:

Genetic events cannot account for the complexity of human carcinogenesis alone. Mutations of epigenetic regulators and aberrations of their expression patterns have been detected in various human malignancies. Methylation of histone H3 at lysine 4 (H3K4me), is an evolutionarily conserved histone modification that marks regions of active transcription and regulates cell growth, migration, and invasion. The MLL/KMT2 family of histone methyltransferases specifically methylate histone H3 at lysine 4.

Objective:

The aim of this study was to explore the role of KMT2C/MLL3 as well as key histone modification activating markers, such as H3K4me2 and H3K4me3 in a cohort of surgically resected human lung adenocarcinomas in an effort to reveal possible biomarkers for lung adenocarcinoma diagnosis and prognosis and potential therapeutic targets.

Method:

The immunohistochemical expression of KMT2C/MLL3, H3K4me2 and H3K4me3 was analyzed in formalin fixed paraffin embedded tissue from 96 patients with lung adenocarcinoma. Results were associated with clinicopathologic parameters and patient’s prognosis.

Results:

Nuclear expression of KMT2C/MLL3 in epithelial cells was independently associated with shorter overall survival. Cytoplasmic H3K4me2 expression was associated withT stage and nuclear H3K4me2 expression was associated with female gender and patients’ prognosis. The latter association persisted after multivariate analysis. No association was found between H3K4me3 expression and clinicopathological data or disease outcome in our cohort of patients.

Conclusion:

These results suggest that the pattern of histone modifications and KMT2C/MLL3 expression can be used as an independent prognostic factor in lung adenocarcinoma, revealing that chromatin remodeling is criticallyinvolved in cancer progression.
Multi-Strategy Learning for Recognizing Network Symptoms
Authors: Sobh Tarek S.
Published: September 2020

Background:

Many network symptoms may happen due to different reasons in today's computer networks. The
finding of a few kinds of these interesting symptoms is not direct. Therefore, an intelligent system is presented for
extracting and recognizing that kind of network symptoms based on prior background knowledge.

Methods:

Here, the main target is to build a network-monitoring tool that can discover network symptoms and provide
reasonable interpretations for various operational patterns. These interpretations are discussed with the purpose of
supporting network planners/administrators. It introduces Multi-Strategy Learning (MSL) that can recognize network
symptoms. Repeated symptoms or sometimes a single event of heavy traffic networks may lead us to recognize various
network patterns that maybe expressed for discovering and solving network problems.

Results:

To achieve this goal an MSL system that can accommodate network observations. The first technique is done in
an empirical manner. It focuses on selecting subsets data traffic by using certain fields from a group of records related to
database samples using queries. The data abstraction is accomplished and various symptoms are extracted. A second
technique is based on explanation-based learning. It produces a procedure that obtains operational rules. These rules may
lead to network administrators solving some problems later. By using only one formal training example in the domain
knowledge (network), we can learn and analyze in terms of this knowledge.
In this work, to store and maintain network-monitoring traffic, network events, and the knowledge base for implementing
the above techniques a Hadoop and a relational database are used.

Discussion:

Using EBL only is not suitable and it cannot take the same props like other types of available training data set
as SBL can. EBL does not need only a complete domain theory but also need consistent domain theory. This reduces the
suitability of EBL as knowledge acquisition. For this reason, we used EBL for discovering the pattern of network
malfunction in case of a single example only in order to take a complete solution for this example.

Conclusion:

Hence, the proposed system can discover abnormal patterns (symptoms) of the underlying network traffic. A
real network using our MSL, as such, could recognize these abnormal patterns.
The network administrator can adapt the current configuration according to advice and observations that come from that
intelligent system in order to avoid the problems that may currently exist or it may happen in the near future. Finally, the
proposed system is capable to extract different symptoms (behaviors and operational patterns) and provide sensible advice
in order to support network-planning activity.
Formal Specification and Verification of Data Separation for Muen Separation Kernel
Authors: Bhushan Ram C. , Yadav Dharmendra K.
Published: September 2020

Introduction:

Development of integrated mixed-criticality systems is becoming increasingly popular for
application-specific systems, which needs separation mechanism for available onboard resources and the processors
equipped with hardware virtualization. Hardware virtualization allow the partitions to physical resources, which include
processor cores, memory, and I/O devices, among guest virtual machines (VMs). For building mixed criticality computing
environment, traditional virtual machine systems are inappropriate because they use hypervisors to schedule separate VMs
on physical processor cores. In this article, we discuss the design of an environment for mixed-criticality systems: The
Muen an x86/64 separation kernel for high assurance. The Muen Separation Kernel is an Open Source microkernel which
has no runtime errors at the source code level. The Muen separation kernel has been designed precisely to encounter the
challenging requirements of high-assurance systems built on the Intel x86/64 platform. Muen is under active development,
and none of the kernel properties of it has been verified yet. In this paper, we present a novel work of verifying one of the
kernel properties formally.

Method:

The CTL used in NuSMV is a first-order modal along with data-depended processes and regular formulas. CTL
is a branching-time logic, meaning that its model of time is a tree-like structure in which the future is not determined;
there are different paths in the future, any one of which might be an actual path that is realized . This section shows the
verification of all the requirements mentioned in section 3. In NuSMV tool the command used for verification of the
formulas written in CTL is checkctlspec -p ”CTL-expression”. The nearest quantifier binds each occurrence of a variable
in the scope of the bound variable, which has the same name and the same number of arguments.

Result:

Formal methods have been applied to various projects for specification and verification purpose. Some of them
are the SCOMP , SeaView , LOCK,and Multinet Gateway projects. The TLS was written formally. Several mappings
were done between the TLS and the SCOMP code: Informal English language to TLS, TLS to actual code , and TLS to
pseudo-code. The authors present an ACL2 model for a generic separation kernel also known as GWV approach.

Conclusion:

We consider the formal verification of data separation property which is one of the crucial modules to
achieve the separation functionality. The verification of the data separation manager is carried out on the design level
using the NuSMV tool. Furthermore, we present the complete model of the data separation unit along with its code written
in the NuSMV modelling language. Finally, we have converted the non-functional requirements into the formal logic,
which then has verified the model formally.
Resource Efficient Deployment and Data Aggregation in Pervasive IoT Applications (Smart Agriculture)
Authors: Zahoor Saniya , Naaz Roohie
Published: September 2020

Aims:

Internet of Things (IoT) is the evolution of the Internet designed to sense, collect,
analyze and distribute the data via IoT devices that form its core component. An important aspect of
pervasive IoT applications is its resource-constrained devices. Most of the real-time Edge-IoT applications
generate a huge amount of data, which add to the resource consumption in these devices. To save
resources in such applications, efficient node deployment and data aggregation techniques can be used.
This paper presents the design and modeling of node deployment and data aggregation in Edge-IoT
applications along with the homogeneous and heterogeneous network scenarios for smart agriculture.

Objectives:

To save resources in such applications, efficient node deployment and data aggregation
techniques can be used. This paper presents the design and modeling of node deployment and data
aggregation in Edge-IoT applications along with the homogeneous and heterogeneous network scenarios
for smart agriculture.

Methods:

For heterogeneous scenarios, we propose a clustering approach, Superior Aggregator Resource
Efficient Clustering (SAREC), to address the resource constraints in pervasive Edge-IoT applications.
The comparison of homogeneous and heterogeneous networks is based on LEACH and
SAREC protocols, respectively.

Results:

The results show that SAREC is 25% more efficient in energy utilization and network lifetime
than LEACH. The results also show that SAREC is more efficient in terms of storage and processing
time as compared to LEACH.

Conclusion:

Node deployment is an important aspect in determining the architecture, which plays an
important role in resource management in pervasive applications of IoT. The IoT nodes are distributed
in a selected geographical location and the topology of the network is pre-decided to form an
Edge-IoT network. In such an environment, the nodes are deployed to sense, aggregate and analyze
the data. This paper presents a pervasive Edge-IoT network along with the mathematical modeling
consisting of deployment and aggregation models. An Edge-IoT network for smart agriculture has
been deployed and analysis of resource utilization has been performed in homogeneous and heterogeneous
scenarios of the network. The resource limitations in pervasive IoT network motivated us to
develop a SAREC approach for such Edge-IoT applications that optimizes the use of resources. The
comparison of the proposed SAREC protocol is made with respect to LEACH protocol on the basis
of energy, network lifetime, number of alive nodes, storage and processing time. The results show
that SAREC protocol is 25% more efficient in energy utilization and network lifetime than LEACH.
It is also evident from the results that the SAREC is more efficient in terms of storage and processing
time as compared to LEACH.

Published: September 2020

Cilj: Cilj rada bio je ispitati oblik Blumensaatove linije te utvrditi položaj lateralnog interkondilarnog grebena u odnosu na nju. Ispitanici i metode: U radu je korišteno 12 preparata femura sa Zavoda za anatomiju Medicinskog fakulteta u Rijeci. Na svakom preparatu tankom savitljivom žicom obilježen je lateralni interkondilarni greben. Učinjena je postranična rendgenska snimka femura uz potpuno preklapanje kondila. Na snimkama je analiziran oblik Blumensaatove linije, razlika u rendgenološkoj gustoći prikaza pojedinih dijelova te položaj lateralnog interkondilarnog grebena u odnosu na Blumensaatovu liniju. Rezultati: Na rendgenološkom prikazu Blumensaatova linija bila je ravna u 25 % preparata. U 75 % preparata stražnji dio linije bio je konveksan u smjeru prema distalno. S obzirom na radiografsku gustoću Blumensaatove linije mogla se podijeliti u tri dijela. Prednji i stražnji dio imali su gustoću intenziteta kortikalne kosti, dok je gustoća srednjeg dijela odgovarala intenzitetu spongiozne kosti. Lateralni interkondilarni greben spaja se s Blumensaatovom linijom u točki koja stražnji segment dijeli u omjeru 58 % : 42 %. Lateralni greben s Blumensaatovom linijom zatvara kut od 62.40 stupnjeva. Zaključak: Blumensaatova linija u 75 % analiziranih preparata nije ravna, već je u stražnjem dijelu zaobljena s konveksitetom usmjerenim prema distalno. Na profilnoj RTG snimci LIR koljena zatvara kut od 62.40 stupnjeva.

Cilj: Istražiti jesu li nakon ozljede prednjeg križnog ligamenta koljena aktivni mehanizmi stabilizacije zgloba, potaknuti vježbama propriocepcije i ravnoteže tijekom programa rehabilitacije, dovoljni za uspostavljanje normalne funkcije zgloba, praćenjem živčano-mišićne kontrole na nestabilnoj podlozi u ranim razdobljima od ozljede, odnosno operacije rekonstrukcije prednjeg križnog ligamenta (od 1 mjesec do 1 godine). Ispitanici i metode: U kliničko istraživanje bilo je uključeno 53 ispitanika s ozljedom prednjeg križnog ligamenta (PKL) koljena, liječenih konzervativno/operacijski. Svi su nakon ozljede/operacije proveli rehabilitacijski program s naglaskom na vježbama na nestabilnoj podlozi za poticanje živčano-mišićne koordinacije i ravnoteže. Statičku i dinamičku stabilnost pratili smo i mjerili aparatom SportKAT 2000. Usporedbu rezultata vršili smo prema usporedbenoj skupini zdravih ispitanika i/ili prema zdravom ekstremitetu istog ispitanika. Rezultati: Koristeći se Sport KAT metodom, pronašli smo disfunkciju neuromišićne kontrole u održavanju statičke i dinamičke stabilnosti zgloba i ravnoteže u promatranim skupinama pacijenata određivanjem statičkih i dinamičkih ravnotežnih indeksa. Vježbe živčano-mišićne koordinacije, kao dio rehabilitacijskog protokola nakon ozljede PKL-a koljena, vrlo brzo dovode do poboljšanja obaju ravnotežnih indeksa (p < 0,001), u obje skupine pacijenata. No, ako se navedene vježbe svakodnevno ne izvode, dinamički ravnotežni indeks pogoršava se u neoperiranoj skupini, dok se nakon operacijske stabilizacije zgloba uspostavlja „normalizacija” ravnoteže (p < 0,001). Zaključak: S ciljem rehabilitacije neurosenzoričkih i propriocepcijskih oštećenja nastalih nakon ozljede PKL-a koljena liječenih konzervativno/operacijski, potrebno je koristiti vježbe koje stimuliraju dinamičke stabilizatore zgloba, preko mehanizama neuromišićne ko-kontrakcije tijekom održavanja ravnoteže. Spomenuto predstavlja znanstveni doprinos ovog rada s naglašavanjem važnosti živčano-mišićne koordinacije u rehabilitaciji donjeg ekstremiteta pri održavanju stabilnosti zglobova.

Cilj: Anatomska tehnika rekonstrukcije predstavlja zlatni standard pri operacijskom liječenju lezija prednjeg križnog ligamenta. Kod postavljanja femoralnog tunela glavni orijentir predstavlja lateralni interkondilarni greben. Greben se nalazi uz prednji rub hvatišta ligamenta i tuneli se postavljaju ispod njega, u centar hvatišta ligamenta. Cilj ove studije je opisati položaj grebena u odnosu na intaktno femoralno hvatište. Materijali i metode: U studiji je korišteno 10 svježe smrznutih kadaveričnih zglobova koljena. Nakon što je uklonjen medijalni kondil femura, vizualno i uz palpaciju analizirano je područje femoralnog hvatišta ligamenta, i to najprije uz očuvan bataljak prednjeg križnog ligamenta, a zatim nakon uklanjanja čitavog hvatišta. Rezultati: Uz održani ligament, u 70 % preparata niti jedan dio lateralnog interkondilarnog grebena nije bio vidljiv izvan hvatišta. U 20 % preparata greben je bio vidljiv samo iznad posterolateralnog snopa prednjeg križnog ligamenta. Nakon što smo odstranili sva vlakna hvatišta prednjeg križnog ligamenta, u jednom preparatu nismo sa sigurnošću mogli odrediti postojanje grebena. Zaključak: U 90 % ispitivanih preparata lateralni interkondilarni greben bio je unutar hvatišta prednjeg križnog ligamenta. Navedeno bi trebalo uzeti u obzir prilikom anatomske rekonstrukcije ovog ligamenta.

Postoperative imaging is necessary for assessing the technical success of the procedure and state of the cartilage healing, as well as for identifying potential complication. A plenty of radiological methods are available today in assessing the articular cartilage: radiography, computed tomography and thomositesis, ultrasonography and magnetic resonance. Radiography is the most used radiological modality but with high limitations in evaluation of the articular cartilage repair. Computed tomography and tomosynthesis are useful only after intraarticular contrast media injection (arthrography) and offer the evaluation of the cartilage surface but with the harmful influence of ionizing radiation. Magnetic resonance (MR) imaging provides non-invasive assessment of the entire joint including evaluation of the cartilage changes and lesions as well as the assessment of the repair site and all other joint tissues. Using compositional MR imaging of cartilage we may get information about its molecular status, specifically in regard to its collagen and glycosaminoglycan content. This article is a review of all imaging methods, in cartilage repair evaluation stressing novel imaging methods representing their advantages and limitations in cartilage repair evaluation.

Izolirana rekonstrukcija prednjeg križnog ligamenta (ACL) predstavlja zlatni standard u kirurškom liječenju rupture prednjeg križnog ligamenta. No, neuspjeh cijeljenja presatka i ostatna rotacijska nestabilnost koljena i dalje su česte postoperativne komplikacije. Anterolateralni ligament (ALL) i njegova uloga u kontroli rotacijske stabilnosti dobila je značajan interes 2013. nakon objave njegova „ponovnog otkrića”. Ta ligamentarna struktura, opisana još davne 1879., potječe od proksimalnog i stražnjeg dijela lateralnog epikondila bedrene kosti i hvata se na goljeničnoj kosti, na sredini između Gerdyjeva tuberkla i glavice fibule. Biomehanička ispitivanja pokazala su da anterolateralni ligament djeluje kao pasivni stabilizator koljena tijekom unutarnje rotacije koljena, i kod rupture ACL-a i lateralnih struktura koljena odgovoran je za nastanak pivot-shift fenomena. Pokazalo se da izolirana rekonstrukcija ACL-a u pacijenata s ozljedom ACL-a i ALL-a ne može vratiti normalnu kinematiku koljena, za razliku od njihove kombinirane rekonstrukcije. Uz to, dosadašnja literatura nudi brojne dokaze u smislu poboljšanja stabilnosti koljena nakon kombiniranog postupka rekonstrukcije ACL-a i ALL-a. Štoviše, nedavne kliničke studije pokazale su da ALL ima zaštitni učinak na očuvanje presatka ACL-a, kao i na brži ponovni povratak u sport i opće zadovoljstvo pacijenata s operativnim zahvatom. Ovaj pregledni rad ima za cilj dati pregled dosadašnjeg znanja anatomije, funkcije i učinka rekonstrukcije ACL-a i ALL-a u pacijenata s puknućem ACL-a.

Cilj: Cilj rada bio je prikazati da i manje traume u adolescentno doba mogu uzrokovati avulziju tuberositasa tibije te ukazati na mogućnost nastanka kompartment sindroma. Prikaz slučaja: Kod dječaka u dobi od 15 godina pri promjeni smjera kretanja došlo je do avulzije tuberositasa tibije. Ozljeda je popraćena velikim edemom. Nakon operacije razvila se pareza peronealnog živca koja je uz medikamentoznu i fizikalnu terapiju regredirala u cijelosti. Zaključak: Pri sumjnji na avulziju tuberositasa tibije potrebna je žurna dijagnostika i liječenje. Zbog mogućeg nastanka sindroma kompartmenta potreban je pojačan nadzor u perioperacijskom periodu.

Cilj: Prikazati iskustva u operacijskom liječenju sportskih ozljeda i oštećenja ručnog zgloba i šake u posljednjih 10 godina. Ispitanici i metode: U ovo istraživanje uključeno je 70 pacijenata kod kojih je učinjeno 70 operacija zbog sportske ozljede ili oštećenja ručnog zgloba i šake u periodu od 1. 3. 2010. do 31. 3. 2020. u Klinici za ortopediju i traumatologiju Lovran. Rezultati: Od 70 pacijenata uključenih u ovo istraživanje, njih 14 (20 %) je ženskog spola, a 56 (80 %) muškog spola. Raspon dobi pacijenata je od 10 do 50 godina. Prosječna dob pacijenata iznosi 23,7 ± 8,5 godina. Kod 35 (50 %) pacijenata bila je zahvaćena lijeva strana, a kod preostalih 35 (50 %) pacijenata desna strana. Kod 34 (49 %) pacijenata sportskom ozljedom ili oštećenjem bila je zahvaćena šaka, dok je kod 36 (51 %) pacijenata sportskom ozljedom ili oštećenjem bio zahvaćen ručni zglob. Od operacijski liječenih sportskih ozljeda u području šake (28) najzastupljeniji su operacijski zahvati osteosinteze prijeloma metakarpalnih kostiju (20) i falangi prstiju (8). Za razliku od operacijski liječenih sportskih ozljeda u području šake, učestalije je operacijsko liječenje sportskih oštećenja negoli ozljeda u području ručnog zgloba (P < 0,001). Zaključci: Ovo je prvo istraživanje u našoj populaciji kojim su dobiveni podaci o vrstama sportskih ozljeda i oštećenja ručnog zgloba i šake liječenih operacijski u posljednjih 10 godina. Gotovo 10 % operacija u području ručnog zgloba i šake su operacije sportskih ozljeda i oštećenja. Iako su prijelomi najčešći uzrok operacijskog liječenja sportskih ozljeda ručnog zgloba i šake, ozljede i oštećenja mekih tkiva ručnog zgloba i šake također su učestali uzrok operacijskog liječenja.
Post-Rainy Season Pigeonpea Holds Promise for the Diversification of Cropping Systems

Published: September 2020

The temporal and spatial intensity of rainfall in north-east plains (Central and Eastern Uttar Pradesh, Bihar, Jharkhand, West Bengal, Assom and North-Eastern states) often leads to temporary waterlogging, causing partial to complete mortality of pigeonpea seedlings during rainy season. Post-rainy season (September) plantings may be adopted as an alternate approach to address the issue of waterlogging and crop diversification. Research conducted at the ICAR-RCER, Patna has shown that sowing of ‘Pusa 9’ during second week of September after harvest of quality protein green cob maize provided up to 3.0 t/ha grain yield under zero tillage with optimum crop management practices (one hand weeding, one-two insecticide spray of imidacloroprid @1mL/L water at 10 days’ interval commencing from second fortnight of February). Similarly, ‘IPA 203’ sown on September 20, 2018 yielded more than 3.0 t/ha under conventional tillage practices (N: P: K: 20:50:0; two hand weeding; one irrigation during second fortnight of December and two spray of the same insecticide at the same interval). These findings indicate that the system is agronomically feasible, economically highly remunerative and ecologically sustainable to bring about diversification in upland ecology of north-east plains of India.
