Mechanism of Inhibition of Hydroxyapatite Nanoparticles on Cancer Cells and Recent Advances in the Field
Authors: Rasouli Mohammad , Naghib Seyed Morteza
Published: July 2021

Background:

Calcium phosphates are chemically similar to bone minerals. The biocompatibility,
bioactivity, and high similarity of these substances to body organs such as bone have
made them a good choice for disease diagnosis and treatment. Here, the main use of calcium phosphates
is diagnosis and treatment of cancers. Hydroxyapatite is a bioactive material with a high affinity
for DNA and protein. Recently, hydroxyapatite nanoparticles exhibit different properties than
those of bulk hydroxyapatite in chemistry and biology. In general, the anticancer effects of hydroxyapatite
nanoparticles have been attributed to high amounts of endocytosis in cancer cells and inhibits
of protein synthesis in cells.

Methods:

Herein, we evaluated the structure, properties, and methods of synthesis of hydroxyapatite
nanoparticles. Moreover, the mechanism of inhibition of hydroxyapatite nanoparticles on cancer
cells and recent advances in this field have been examined.

Conclusion:

Hydroxyapatite nanoparticles had the ability to eliminate the development of cancer
cells in vitro and in vivo. In the live tissue environment, injection of hydroxyapatite nanoparticles at
the tumor’s surrounding area had a significant decrease in tumor size (about 50%).

Published: July 2021

Since the ‘Coronavirus Disease 2019’ (COVID-19) struck the world and Malaysia, the general attention of the media and leaders has been focused on the high population density areas that have high infection rates and deaths. This article aims to rethink population density in urban development policy, thus providing development for policy direction in the post-COVID-19 era in Malaysia. The available national development planning policies in Malaysia, i.e., the National Physical Plan and the National Urbanisation Policy, and scholarly articles related to the population density topic were investigated through a scoping literature review and a keyword analysis. The findings showed mixed results in terms of the relationship between dense areas causing higher rates of COVID-19 infection and death rates. This article argues that policies related to spatial urban planning should continuously advocate dense city planning in considering how to achieve economic, social, and environmental sustainability and human quality of life. To this extent, this article contributes to the densification topic in spatial urban planning policies in terms of their application in the post-COVID-19 era, which needs urgent direction and clarification.

Published: July 2021

Malaysian government aims to transform rural areas into economic focal points, improves rural livelihoods, living environment and narrows the life quality gaps between those living in urban and rural areas. Inspired by the government directive-aspirations and the emergence of new technologies in national and global rural practices, this paper attempts to discuss the formulation of a framework for rural development in Malaysia based on a modern approach. The process undertakes two main stages, namely focused literature study and review of the national existing policies and strategies to identify the key assessment elements and criteria for modern rural development. The next stage was to conduct an expert view survey to validate the developed elements and criteria, and then formulate a Malaysia modern rural development framework (FMRD). The FMRD was finally formulated by incorporating the elements and criteria promoted in the national policies and strategies and integrating them with smart technologies and ICT practices to reflect a holistic approach for rural issues. This paper concludes that the FMRD is a timely approach for the rural assessment measure to maximise its performance towards the future niches in Malaysia - rural liveability-resilient-and-smart.

Published: July 2021

Sustainability has emerged as a critical concern in any viable physical planning and development. Hence, the Malaysian government has promoted the concept of green procurement also known as Government Green Procurement (GGP) that aims to minimize environmental degradation. In GGP, life cycle perspective thinking is introduced where life-cycle cost (LCC) tools act as decision-making in controlling the initial and future value of building ownership. Despite the increasing importance of green procurement and LCC in the planning phase of green projects, the viability and implementation of LCC is still lacking. Many have stated the benefits of LCC in green procurement for green building projects, however the criteria of LCC are not clearly determined. The study aims to determine the important level of LCC components relating to the green project planning phase. Questionnaire survey was distributed to 50 respondents composed of project team members that were involved in the selected green government projects. 32 respondents returned their responses to the survey. The results revealed that the highest rank of LCC components in green procurement is energy consumption cost, greenhouse gas (GHG) savings cost, acquisition cost, energy simulation cost and utilities cost. These results would elevate the use of LCC in the green procurement adoption and viability of green projects.

Authors: Zihannudin Nur Zafira , Adi Maimun Nurul Hana , Ibrahim Nurul Liyana
Published: July 2021

The existence of Brownfield sites is one of the main challenges that Malaysia must face due to financial, administrative and policy problems. The negative environmental and social impacts of Brownfield sites jeopardise residents’ health and well-being, causing nearby areas to be less desirable for occupation and investment. These impacts result in price discounts. Hence, this research aims to establish the sensitivity of the property market towards Brownfield sites through a critical review. An overview of previous studies shows that property prices are sensitive towards Brownfield sites. This indicates that the proximity to a Brownfield site is considered when making property purchase decisions. Thus, property valuers, planners and developers should consider the Brownfield factor during property planning, development and valuation.

ClinicalTrials.gov as a Source of Information About Expanded Access Programs: Cohort Study
Authors: Borysowski Jan , Górski Andrzej
Published: July 2021

Background

ClinicalTrials.gov (CT.gov) is the most comprehensive internet-based register of different types of clinical studies. Expanded access is the use of unapproved drugs, biologics, or medical devices outside of clinical trials. One of the key problems in expanded access is the availability to both health care providers and patients of information about unapproved treatments.

Objective

We aimed to evaluate CT.gov as a potential source of information about expanded access programs.

Methods

We assessed the completeness of information in the records of 228 expanded access programs registered with CT.gov from February 2017 through May 2020. Moreover, we examined what percentage of published expanded access studies has been registered with CT.gov. Logistic regression (univariate and multivariate) and mediation analyses were used to identify the predictors of the absence of some information and a study’s nonregistration.

Results

We found that some important data were missing from the records of many programs. Information that was missing most often included a detailed study description, facility information, central contact person, and eligibility criteria (55.3%, 54.0%, 41.7%, and 17.5% of the programs, respectively). Multivariate analysis showed that information about central contact person was more likely to be missing from records of studies registered in 2017 (adjusted OR 21.93; 95% CI 4.42-172.29; P<.001). This finding was confirmed by mediation analysis (P=.02). Furthermore, 14% of the programs were registered retrospectively. We also showed that only 33 of 77 (42.9%) expanded access studies performed in the United States and published from 2014 through 2019 were registered with CT.gov. However, multivariate logistic regression analysis showed no significant association between any of the variables related to the studies and the odds of study nonregistration (P>.01).

Conclusions

Currently, CT.gov is a quite fragmentary source of data on expanded access programs. This problem is important because CT.gov is the only publicly available primary source of information about specific programs. We suggest the actions that should be taken by different stakeholders to fully exploit this register as a source of information about expanded access.
Mental Health Screening in General Practices as a Means for Enhancing Uptake of Digital Mental Health Interventions: Observational Cohort Study
Authors: Whitton Alexis E , Hardy Rebecca , Cope Kate , Gieng Chilin , Gow Leanne , MacKinnon Andrew , Gale Nyree , O'Moore Kathleen , Anderson Josephine , Proudfoot Judith , Cockayne Nicole , O'Dea Bridianne , Christensen Helen , Newby Jill Maree
Published: July 2021

Background

Digital mental health interventions stand to play a critical role in managing the mental health impact of the COVID-19 pandemic. Thus, enhancing their uptake is a key priority. General practitioners (GPs) are well positioned to facilitate access to digital interventions, but tools that assist GPs in identifying suitable patients are lacking.

Objective

This study aims to evaluate the suitability of a web-based mental health screening and treatment recommendation tool (StepCare) for improving the identification of anxiety and depression in general practice and, subsequently, uptake of digital mental health interventions.

Methods

StepCare screens patients for symptoms of depression (9-item Patient Health Questionnaire) and anxiety (7-item Generalized Anxiety Disorder scale) in the GP waiting room. It provides GPs with stepped treatment recommendations that include digital mental health interventions for patients with mild to moderate symptoms. Patients (N=5138) from 85 general practices across Australia were invited to participate in screening.

Results

Screening identified depressive or anxious symptoms in 43.09% (1428/3314) of patients (one-quarter were previously unidentified or untreated). The majority (300/335, 89.6%) of previously unidentified or untreated patients had mild to moderate symptoms and were candidates for digital mental health interventions. Although less than half were prescribed a digital intervention by their GP, when a digital intervention was prescribed, more than two-thirds of patients reported using it.

Conclusions

Implementing web-based mental health screening in general practices can provide important opportunities for GPs to improve the identification of symptoms of mental illness and increase patient access to digital mental health interventions. Although GPs prescribed digital interventions less frequently than in-person psychotherapy or medication, the promising rates of uptake by GP-referred patients suggest that GPs can play a critical role in championing digital interventions and maximizing the associated benefits.

Published: July 2021

Background

A digital tool, Multiple Sclerosis Progression Discussion Tool (MSProDiscuss), was developed to facilitate discussions between health care professionals (HCPs) and patients in evaluating early, subtle signs of multiple sclerosis (MS) disease progression.

Objective

The aim of this study is to report the findings on the usability and usefulness of MSProDiscuss in a real-world clinical setting.

Methods

In this cross-sectional, web-based survey, HCPs across 34 countries completed an initial individual questionnaire (comprising 7 questions on comprehensibility, usability, and usefulness after using MSProDiscuss during each patient consultation) and a final questionnaire (comprising 13 questions on comprehensibility, usability, usefulness, and integration and adoption into clinical practice to capture the HCPs’ overall experience of using the tool). The responses were provided on a 5-point Likert scale. All analyses were descriptive, and no statistical comparisons were made.

Results

In total, 301 HCPs tested the tool in 6974 people with MS, of whom 77% (5370/6974) had relapsing-remitting MS, including those suspected to be transitioning to secondary progressive MS. The time taken to complete MSProDiscuss was reported to be in the range of 1 to 4 minutes in 97.3% (6786/6974; initial) to 98.2% (269/274; final) of the cases. In 93.54% (6524/6974; initial) to 97.1% (266/274; final) of the cases, the HCPs agreed (4 or 5 on the Likert scale) that patients were able to comprehend the questions in the tool. The HCPs were willing to use the tool again in the same patient, 90.47% (6310/6974; initial) of the cases. The HCPs reported MSProDiscuss to be useful in discussing MS symptoms and their impact on daily activities (6121/6974, 87.76% initial and 252/274, 92% final) and cognitive function (5482/6974, 78.61% initial and 271/274, 79.2% final), as well as in discussing progression in general (6102/6974, 87.49% initial and 246/274, 89.8% final). While completing the final questionnaire, 94.9% (260/274) of the HCPs agreed that the questions were similar to those asked in regular consultation, and the tool helped to better understand the impact of MS symptoms on daily activities (249/274, 90.9%) and cognitive function (220/274, 80.3%). Overall, 92% (252/274) of the HCPs reported that they would recommend MSProDiscuss to a colleague, and 85.8% (235/274) were willing to integrate it into their clinical practice.

Conclusions

MSProDiscuss is a usable and useful tool to facilitate a physician-patient discussion on MS disease progression in daily clinical practice. Most of the HCPs agreed that the tool is easy to use and were willing to integrate MSProDiscuss into their daily clinical practice.
A Philosophical Reexamination of Durkheim’s Socio-political Deviation
Authors: Ding John Zijiang
Published: July 2021

Durkheim’s theory of deviation has powerfully influenced the scholars of sociology. His idea is still one of the fundamental theories in sociology. Durkheim’s whole investigation is threefold: first, to establish a framework of theory; second, to solidify it once established; and third, to promote its greater perfection. In general, Durkheim’s establishment of this framework was fruitful. This paper attempts: 1) to re-formalize the rules of socio-political deviation; 2) to re-correlate socio-political deviation and other socio-political phenomena; 3) to re-justify the necessity and causality of socio-political. We can concede that Durkheim was an original deviser of a blueprint for a new theoretical mansion, but at the same time, one should realize that he was also a failure as a builder of this construction.

Published: July 2021

COVID -19 pandemic is the defining global health crisis of our time which eventually led to the use of face mask and maintaining safe social distancing, which became mandatory for reducing the rate of transmission of virus. This has parallelly raised a challenge in identifying people since most of the face regions are hidden inside the mask. So we came up with a system which identifies maked face along with which it ensures whether people follows safe social distancing or not. For this purpose we are using deep convolutional neural network (CNN) along with this MLP is also used for classification process. We also incooperates an efficient system that makes real time automated monitoring of people to detect safe social distancing and use of thermal cameras for detecting the body temperature. Thus the entire system favours the society by saving time and the automated inspection reduces the manpower to inspect the public.
Arduino Based Solar Tracking System for Energy Improvement of PV Solar Panel
Authors: Dinker Smita
Published: July 2021

Solar energy is a clean, easily accessible and abundantly available alternative energy source in nature. Getting solar energy from nature is very beneficial for power generation. Using a fixed Photovoltaic panels extract maximum energy only during 12 noon to 2 PM in Nigeria which results in less energy efficiency. Therefore, the need to improve the energy efficiency of PV solar panel through building a solar tracking system cannot be over-emphasized. Photovoltaic panels must be perpendicular with the sun in order to get maximum energy. The methodology employed in this work includes the implementation of an Arduino based solar tracking system. Light Dependent Resistors (LDRs) are used to sense the intensity of sunlight and hence the PV solar panel is adjusted accordingly to track maximum energy. The mechanism uses servo motor to control the movement of the solar panel. The microcontroller is used to control the servo motor based on signals received from the LDRs. The result of this work has clearly shown that the tracking solar panel produces more energy compared to a fixed panel.
Analysis of Fine Gained Air Quality Using Deep Learning
Authors: Singh Shivangi
Published: July 2021

With the rapid development of industrialization and urbanization, air pollution is increasing at an alarming rate in many developing countries. The four air pollutants which are becoming a concerning threat to human health are namely respirable particulate matter, nitrogen oxides, particulate matter and sulphur dioxide. The models which are currently used for air quality prediction by comparing to the AQI indexes do not give satisfactory results, which inspired us to examine the methods of predicting air quality based on deep learning using the K-Mean Clustering algorithm and Image Processing Technique. The interpolation, prediction, and feature analysis of fine-gained air quality are three important topics in the area of air computing. A good interpolation helps to estimate the limited air quality monitoring stations whose distribution is uneven in a city; an accurate prediction provides valuable information to protect humans and take necessary measures to reduce the effect of air pollution; a reasonable feature analysis is used to provide a more effective and general model. Overall, finding solutions to these topics can bring out extremely useful information to support air pollution control, and consequently generate great societal and technical impacts.

Authors: Hasan S. M Mehady
Published: July 2021

A comparison between NACA 0012 and NACA 2412 has been made by comparing the lift co- efficient, drag co-efficient, pressure contour and velocity contour at various angles of attack. The process has been done taking steady state flow around NACA-0012 and NACA-2412 airfoil using 1m chord length and a velocity of 88.65m/s. The main aim is to understand the aerodynamic characteristics of both the airfoils at different angles of attack and draw a conclusion on which performs better under the same conditions. Modelling and numerical analysis has been carried out by using commercially available CFD software, which is a convenient method of analysis since computational methods are more preferred to experimental methods due to low expenses involved. The numerical results demonstrated are compatible with those of the theory. This confirms the validity of using Computational Fluid Dynamics (CFD) as a reliable alternative to experimental procedures.
Design of Axial Magnetic Coupling for Compressor
Authors: Khot Dr. Maruti M.
Published: July 2021

A mechanical device which raises the pressure of a gas by decreasing its volume is called as compressor. A coupling is a device which transmits the power from one end to another end. The purpose of coupling is to join two parts which allowing some degree of misalignment or end movement or both. But in conventional coupling, there are lots of losses like mechanical losses, noise and vibration losses etc. These losses have effects on the efficiency of the system. In mechanical seals, leakages are possible. So, leakage of hazardous chemicals polluting the environment has to prevent. The mechanical seal limits the speed of the compressor as the wear rates of the seal are proportional to speed. To improve the efficiency of coupling and to minimize the mechanical losses of coupling, magnetic coupling is introduced. It is contactless coupling which transfer the power from input shaft to output shaft. MATLAB software is used for analysis of magnetic coupling. This paper represents evaluation of force and torque transmitted by magnetic coupling. The theoretical analysis of magnetic coupling is carried out by using basic principle of electromagnetism. Magnetic coupling is designed to sustain the given load and torque. Permanent disc magnets of NdFeB material are selected for magnetic coupling for high strength of magnetic field. The brass plates are used to hold the magnets.

Design and Fabrication of Solenoid Compressed Hybrid Air Engine
Authors: Yadav Dr. Akhilendra
Published: July 2021

As we are moving towards the developed country, the need of fossil fuel is increasing day by day with increasing population. We need alternative to replace fossil fuel. In IC engine, the chemical energy get converted into mechanical energy, i.e., the low grade energy get converted into high grade energy. The IC engine we use cause more pollution. So to overcome this problem, the electromagnetic force and compressed air is use to run the engine. The solenoid compressed hybrid air engine which uses electric energy and compressed air to run, can replace the use of IC engine. As we pass current through the copper wire winding, the magnetic field generated near the copper wire. The polarity of the magnetic field can vary according to the current. The magnet attached at the piston get attracted up as the polarity of permanent magnet and this force is transferred to the connecting rod and crankshaft assembly, which transfer the reciprocating motion of piston into rotating motion of crankshaft and finally the flywheel. The electromagnetic engine should be more compatible. The electromagnetic engine does not require extra components like cam follower, valves, fuel pump, injectors, fuel tank etc. The strength of magnetic force can be increase by varying the input voltage and current.

A Survey on Intensification Techniques used in Satellite Images
Authors: Tamkhane Bipin D.
Published: July 2021

An image intensification is a required methodology in field of Satellite image research area. The images taken through satellite are captured from very longer distance and because of this images having garbling and noise as lots of airy barriers are present in between the path. The usage of Satellite images is very diverse in research areas like astrological studies, geographical studies, study of geoscience, etc. Nowadays, after taking a snapshot of an image, some of the radiometric or geometric based enhancement techniques are applied on the images taken from satellite but these techniques do not fulfill the requirements in all application areas. This is what there is a need to improvise the quality of an image before it is being actually used. The main objective behind this research work is to understand the different methodologies used in intensification of satellite images and how can we perform more improvements to existing techniques so these type of images which are taken from satellite are intelligible to the human eyes. The meaning of intensification in term of image is nothing but the altering of a look and feel of the image in a way that the information contained by that image is more readily intelligible visually.

Luego de la exégesis de textos fundamentales realizada en el artículo complementario "La míimesis como arte - Primerta Parte : Hermenéutica", en este segundo artículo nos vemos confrontados con el  desafío de transformar la teoría en acción, en práctica musical. En primer lugar, el término "heurística" será explorado, poniendo de relieve  la importancia de las ficciones en la impulsión que lleva a la acción. Los antecedentes de la Heurística Musical serán expuestos a continuación, para continuar con la presentación de esta disciplina de vocación musicológica. Expuestos estos prolegómenos, pasaremos a explicar la propuesta de reconstucción perceptiva de obras, descendiente directa de la mímesis de Aristóteles.  Gracias al pensamiento del Estagirita creemos haber podido realizar la transmutación que nos propusimos originalmente como problemática.
“Con la memoria, con el olvido”: documental musical y dictadura en Chile
Authors: Farias Martin
Published: July 2021

Dentro de un corpus de más de doscientos documentales sobre música producidos en Chile en la postdictadura, un número significativo aborda temas como el exilio, el encarcelamiento y el asesinato de músicos chilenos con posterioridad al golpe de Estado de 1973. En este artículo examino cuatro de estos documentales para mostrar las diversas miradas del pasado traumático del país que emergen desde lo musical y cuáles son los diálogos que establecen con el Chile de hoy. Asimismo, me propongo discutir las reflexiones que estas películas ofrecen sobre el vínculo entre música y política.

Benign Paroxysmal Positional Vertigo (BPPV) is the most common and treatable vestibular disorder. It is commonly seen in the elderly population. BPPV is a type of vertigo that is brought on by change in position of the head with respect to gravity. The objective of this study was to find out the prevalence of appropriate age group of the individuals suffering from BPPV in elderly population. The study was an observational study. A total of 64 people were recruited for the study aged between 60-70 and 71-80yrs that were selected from Krishna hospital Karad through a simple random sampling method. Inclusion and exclusion criteria were used to select the individuals for the study. Individuals of age group between 60-80 years of both the sex were also considered for the study. The individuals who were not included in the study were those not willing to participate, individuals’ history of acute trauma. Demographic data, assent and consent were taken from the individuals and the explanation of the study was given.   The special tests like Dix-Hallpike positioning test, Horizontal roll test and Head pitch test were performed over the individuals. In this study the overall prevalence of age induced BPPV was evaluated according to Dix-Hallpike test it was found that out of 64 individuals 61% were positive for Dix-Hallpike test. Out of 45 males 26 were positive and 13 females from total 19 were indicated Dix-Hallpike test as positive. Thus, this result shows that females are more prone to develop BPPV. This study concluded that BPPV was common among the age group of 71-80 years than the age group of 60-70 years. The study revealed that the individuals in middle old age group are getting more affected by BPPV than the individuals in young old age group. Thus the societal impact which affects the individuals with BPPV can be reduced by making preventive strategies to improve the quality of life and to decrease the disability adjusted years.

Women in postmenopausal period of their life face various physical and physiological changes causing lack of estrogen and progesterone hormones, changes in the reproductive and genitals organs, vasomotor system in the body along with mood related symptoms such as anxiety, etc. Lifestyle, body fat distribution and anthropometric changes adds on to the bone strength in postmenopausal women. It may be a risk factor for osteoporotic fracture, cardiovascular, metabolic diseases, etc. Core strength and stability is greatly influenced by body composition and adiposity. The aim of the study was to correlate the core strength assessed with the Body Mass Index (BMI) among postmenopausal women. The objective of the study is to find the correlation between the core strength assessed with the Body Mass Index using 60° flexion test, Beiring Sorenson test and Unilateral Hip Bridge Endurance test among postmenopausal women with age ranging from 46-70 years. 96 healthy postmenopausal women in Karad city with a natural history of menopause were selected for the study. Based upon BMI values, the subjects were grouped as Underweight (<18.5 kg/m2), Normal weight (18.5-24.9 kg/m2), Overweight (25-29.9 kg/m2 and more). The outcome values for strength were correlated with the BMI of postmenopausal women. In the study, the Pearson correlation(r) was -0.361 and the P value was 0.0003 showing extremely significant correlation between the BMI and 60° Flexion test. For the Beiring Sorenson Test, the Pearson correlation value was -0.305 and the P value was 0.0025 showing very significant correlation between the BMI and Beiring Sorenson Test. Correlation of BMI and Unilateral Hip Bridge Endurance Test shows a Pearson Correlation value of -0.322 and the P value 0.0013 claiming very significant correlation between the BMI and Unilateral Hip Bridge Endurance Test. The study concludes that there is a significantly negative correlation between the core strength and stability with the Body Mass Index among postmenopausal women.
Biometric Estimation for Understanding the Nature of Vorticella Stalk Contraction-Extension Repeated Consequential Cyclic Processes
Authors: Dr. Amit Kumar Verma
Published: July 2021

Vorticella stalk is the storehouse of two types of novel proteins, known with the names of spasmins and batonnets. On the basis of nature of proteins and the arrangements of amino acid residues of these proteins, the repeated consequential cyclic processes of contraction dynamics worked by neutralizing the negatively charged amino acid residues as per the laws obeyed by Heber-Weiss, Nernst and Fenton reactions. H+-integrated physiological performances in combination with pCa (partial pressure of calcium ion concentrations) and DNFB (2,4 – dinitrofluorobenzene/Sanger’s reagent) concentration gradients at the range of 1mM to 5mM represented velocity inclination in acidic medium which were more actively pronounced if it was compared with alkaline medium where permeabilized stalk exaggerated potential biochemical-shift-perturbation if it was in respect of non-permeabilized live specimens in both artificial as well as in natural medium in different experimental trials under controlled electro-physiological instrumental setup conditions. On the basis of these experimental designs it was confirmed that spasmins and batonnets are two different types of novel proteins with multitudes of potential applications in the favour of biomedical engineering devices formulation, then their construction at the nano-scale where H+-integrated pCa dependent electrophysiological nature of recommended proteins were found more ROS (reactive oxygen species) resistant if there was the introduction of DNFB in fixed concentrations than in the acto-myosin as well as tubulin-dynein systems being exclusively controlled under post-translational biochemical reactions catalysed in the light of software based modern bioinformatics’ tools and techniques. In live as well as permeabilized specimens, different types of biochemical reaction kinetics of amino acid residues were performed at different rates among the sequentially determined spasmins and batonnets like novel proteins where molecular orientations and motive-force generation in measurable parameters per millisecond confirmed the electrophysiological significance of Vorticella stalks’ on the basis of colligative nature of novel proteins of saccular compartments of spasmoneme, the well explained active contractile organelle of the stalk in relation with other resembling proteins found in Protein Data Bank (PDB) as centrins, calmodulins and others significantly pronounce their life saving and medicinal properties. This present statement/study was aimed to know the biochemical behaviour of spasmins and batonnets like novel proteins in the light of electrochemical behavior of the Vorticella stalk under some selective chemical stress conditions, that’s why this research helped us to know the ROS resistance properties of novel protein polymers found in stalk. On the basis of which reference proteins as described in this paper can be used as a diagnostic tools in pharmaceutical industries in the favour of molecular medicines and drugs’ designing.

Este artigo resulta de pesquisa que se dedicou ao estudo comparado das políticas esportivas de Brasil e Espanha. Teve como como objetivo principal analisar – de forma comparativa – a legislação esportiva de ambos os países após a constitucionalização do direito ao esporte. Adotando os procedimentos de estudos comparados e a técnica de pesquisa de análise de conteúdo, foram estudadas as legislações infraconstitucionais de Brasil e Espanha que regulamentam o setor esportivo. As análises demonstram: (i) a constituição de uma arquitetura híbrida de gestão da política esportiva, que combina ação tutelar do Estado com autonomização/liberalização do setor privado; (ii) o estímulo à criação de entidades cuja natureza jurídica alinha-se à perspectiva empresarial; (iii) a diversificação de fontes de financiamento ao esporte, em especial o de alto rendimento, mais atrativo ao mercado devido ao potencial de impulsionar a atividade comercial.
