Post-operative residual neuromuscular blockade after the administration of a single intubating dose of intermediate-acting non-depolarising neuromuscular blocking agent in adult elective surgical procedures
Authors: Gollaba Rita Mae J. , Sumalapao Derick Erl P. , Chiong-Perez Mary Ellen M.
Published: July 2020

Objectives:

Post-operative residual neuromuscular blockade may result in life-threatening conditions if not properly managed making it a common and significant concern among anaesthesiologists. Among adult elective surgeries requiring single intubating dose of intermediate-acting non-depolarising neuromuscular blocking agent, the study determined the incidence and risk factors associated with post-operative residual neuromuscular blockade during early post-operative period.

Materials and Methods:

A prospective, open-labelled, non-randomised observational study conducted in an operating room and post-anaesthesia care unit. A total of 175 ASA-PS Class I and II patients admitted in the surgical wards scheduled for elective surgical operation and were administered of a single intubating dose of intravenous intermediate-acting non-depolarising neuromuscular blocking drug. The train-of-four (TOF) method of peripheral nerve stimulation detects the presence of post-operative residual neuromuscular blockade.

Results:

A significant post-operative residual paralysis was identified in specific age groups (26–35, 46–55 and 56–65), in surgical procedures in the orthopaedic service, and among patients who were given a reversal agent. Residual neuromuscular blockade is still present even if the interval between the last dose of muscle relaxant and the measurement of TOF ratio at the post-anaesthesia care unit was long, however, less than that observed in short interval surgeries.

Conclusion:

Clinical importance of residual neuromuscular blockade is still evident up to the present time and the present study recommends routine monitoring of neuromuscular blockade and pharmacologic antagonism in the reversal of non-depolarising neuromuscular blocking drugs.

Authors: Dutt R. Aswini , Jain Rashmi , Bangera Shobith
Published: July 2020

Objectives:

A good conceptual understanding of physiology is very important to build a strong foundation for medical students. It is a daunting job for teachers to emphasise the clinical relevance of basic science subjects as exposure to patients invariably starts after these subjects have been taught. With the introduction of early clinical exposure in the newly revised Indian undergraduate medical curriculum, this problem can be addressed to a certain extent. We developed an integrated simulation module for teaching cardiovascular physiology to pre-clinical students as a part of early clinical exposure.

Materials and Methods:

We included 145 medical students of a Private Medical College of a Deemed to be University in Mangalore, Karnataka, India. The teaching module covered the topics of cardiovascular physiology such as functional anatomy, cardiac cycle, normal electrocardiogram (ECG), arrhythmia, arterial pulse examination, heart sounds and hands-on cardiovascular examination using a variety of simulators. The assessment was done by pre-test and post-test. A retro-pre questionnaire was used to assess their self-perceived knowledge gain and level of clinical skills. Feedback on overall experience was collected from the participants.

Results:

The student feedback showed that learning experience was life-like (98.6%), effective, innovative and enjoyable (99.3%) and making the overall experience of learning easier (95.2%). It also improved participation, communication (93.8%), clinical skills and a better understanding of patient care (99.3%). The results of the retro- pre questionnaire to assess their self-perceived knowledge gain (95%) and level of clinical skills (96%) were highly satisfactory. The assessment of knowledge domain showed 100% of the students achieved pass percentage (>50%) with significant difference among pre- and post-test scores. Faculty (100%) opined that simulation-based teaching resulted in effected learning.

Conclusions:

The use of simulation-based teaching in cardiovascular physiology as part of early clinical exposure leads to enhanced learning and clinical application. This will stimulate interest in subject and promote better learning.

Catalytic Chemoselective Sulfimidation with an Electrophilic [CoIII(TAML)]-Nitrene Radical Complex
Authors: van Leest N.P. , van der Vlugt J.I. , de Bruin Bas
Published: July 2020

The cobalt species PPh4[CoIII(TAMLred)] is a competent and stable catalyst for the sulfimidation of (aryl)(alkyl)-substituted sulfides with iminoiodinanes reaching turnover numbers up to 900 and turnover frequencies of 640 min-1 under mild and aerobic conditions. The sulfimidation proceeds in a highly chemoselective manner, even in the presence of alkenes or weak C-H bonds, as supported by inter- and intramolecular competition experiments. Functionalization of the sulfide substituent with various electron-donating and electron-withdrawing arenes and several alkyl, benzyl and vinyl fragments is tolerated, with up to quantitative product yields. Sulfimidation of phenyl allyl sulfide led to [2,3]-sigmatropic rearrangement of the initially formed sulfimide species to afford the corresponding N-allyl-S-phenyl-thiohydroxylamines as attractive products. Mechanistic studies suggest that the actual nitrene transfer to the sulfide proceeds via (previously characterized) electrophilic nitrene-radical intermediates that afford the sulfimide products via electronically asynchronous transition states, in which SET from the sulfide to the nitrene-radical complex precedes N-S bond formation in a single concerted process.

Published: July 2020

Cyclobenzoins are stable and shape-persistent macrocycles which offer promise as components of optoelectronic and porous materials. We report three new cyclotetrabenzoins, derived from biphenyl, naphthalene, and tolane skeletons. Their synthesis relied on the N-heterocyclic carbene-catalyzed benzoin condensation. Isolated as their acetic esters, these compounds are characterized by structures similar in shape, but larger in size than the parent cyclotetrabenzoin. Alkyne groups of the tolane-based cyclotetrabenzoin were post-synthetically functionalized with Co2(CO)6 moieties under mild reaction conditions.

Published: July 2020

In a world of constant rush towards novel energy sources, hybrid nanomaterials have raised huge interest as their components can synergistically improve the expected performances in terms of power. In this regard, direct methanol oxidation (DMO) is among the most investigated reactions for implementation in portable and other devices. Herein, we report the design of gold-decorated CNT-aryl nanohybrids as electrocatalyst of DMO. In a first step, Azure A (AA), Neutral Red (NR) and Congo Red (CR) dye diazonium salts were reacted with CNTs to provide CNT-Dye nanoscale platforms for the immobilization of gold NPs. This step was conducted with CNT-Dye platforms evenly spread over glassy carbon (GC) electrodes. The CNT-Dye@Au nanohybrid electrode materials served for DMO electrocatalysis. Cyclic voltammograms show that bare CNT-Dye nanohybrids exhibit high electrocatalytic activity, particularly for the CNT-CR nanohybrid which returned a 3-fold improvement. With anchored Au NPs, a further 4 time remarkable increase in the oxidation peak intensity was achieved (i.e. about 12-fold the peak intensity recorded in the absence of any nanocatalyst). The forward to the backward anodic peak current density ratio Jf/Jb was found to be as high as is 1.68. This work provides a simple, elegant and efficient approach for designing robust, nanohybrid electrocatalyst for DMO, based on the smart combination of CNTs, diazotized dyes and gold NPs.

Authors: hatefi Nayyereh , Smith William
Published: July 2020

Ideal{gas thermochemical properties (enthalpy, entropy, Gibbs energy, and heat capacity, Cp) of 49 alkanolamines potentially suitable for CO2 capture applications and their carbamate and protonated forms were calculated using two high{order electronic structure methods, G4 and G3B3 (or G3//B3LYP). We also calculate for comparison results from the commonly used B3LYP/aug-cc-pVTZ method. This data is useful for the construction of molecular{based thermodynamic models of CO2 capture processes involving these species. The Cp data for each species over the temperature range 200 K{1500 K is presented as functions of temperature in the form of NASA seven-term polynomial expressions, permitting the set of thermochemical properties to be calculated over this temperature range. The accuracy of the G3B3 and G4 results is estimated to be 1 kcal/mol and the B3LYP/aug-cc-pVTZ results are of nferior quality..
Simultaneous Detection of Copper, Lead and Mercury in River Water with In-Situ pH Control Using Electrochemical Stripping Techniques

Published: July 2020

ABSTRACT: An electrochemical sensor for the detection of lead, mercury and copper in neutral solutions is described. The electrode is made of two distinct parallel gold interdigitated microband electrodes that can be polarized separately. Biasing one electrode “protonator” sufficiently positive to begin water electrolysis, results in the production of H+ ions which consequently drops the pH in the locality around the other second interdigitated “sensing” electrode. This decrease in pH permits the electodeposition (and consequent stripping) of metals at the sensing electrode without the need to acidify the whole test solution. In this work, the local pH can be adjusted from 1 to 7 in a stable and reproducible way by tailoring the applied potential to the protonator electrode. Using this approach, linear ranges for lead 10-100 ppb, copper 5-100 ppb and mercury 1-75 ppb, respectively were demonstrated which exhibit extremely high sensitivity. This technique allowed detection of these metals in a complex water matrix (river water) without sample pretreatment, with excellent results. The electrode reproducibility is high (RSD < 10%) and the metals can be co-detected when present all together. This is the first demonstration of the in-situ pH control for heavy metal detection using solid state sensors and will unable real time and in situ analysis of heavy metals by unskilled personnel in remote settings.

Published: July 2020

Azithromycin (AZT) is a broad-spectrum antibiotic and is found in ocular tissues when administered systemically. AZT inhibits RNA-dependent protein synthesis and hence has effective bactericidal capability against Staphylococcus aureus, Pseudomonas aeruginosa, which are the primary causative organisms for bacterial infection. In situ ophthalmic gels are systems which undergo a sol-to-gel transformation when instilled in eyes. In situ gels overcome the shortcoming of ophthalmic drops as they get washed out and diluted due to tear fluid. The aim and objective of present study was to formulate in situ ophthalmic gelling systems of Azt and determine in vivo ocular residence time in rat eyes of Tc99 labelled Azt by Micro SPECT. The in situ gel was formulated using Poloxamer 407, which is a temperature-induced gelling agent and HPMC K4M, which is known to increases mucosal adhesivity and enhance viscosity to facilitate sustained release of drug. The formulations developed were evaluated for pH, clarity, viscosity, gelling capacity and % drug release. The selected formulation was subjected to isotonicity and In Vivo Bio-distribution studies. Experimental studies on compatibility showed no interaction between polymers and AZT. AZT was found soluble in PB6.8. All formulations were found clear immediately after preparation and after sterilization & pH after gelation was satisfactorily in the range of 6 to 7. Viscosity and Gelation capacity of in situ gel increased with increase in polymer concentration. Formulations F2 showed desired results w.r.t viscosity, gelation capacity, drug release. In Vivo Biodistribution studies of Tc99 labelled AZT by Micro SPECT showed there was a significant increase in ocular residence time of in situ gel when compared with Tc99 labelled marketed solutions.

The human sacrum is a complex structure and provides accommodation for spinal nerves which stabilises the pelvis. Morphometric measurements of sacrum determine the sex of the individual. The measurement of sacral index using the sacrum bone is considered as one of the best methods for determination of sex. The aim of this study is to find out the importance of sacral index in sexual dimorphism and to compare the findings with various age groups. 100 fully ossified sacral bones were collected from department of Anatomy. Average sacral length and breadth were taken by using sliding Vernier caliper and sacral index was calculated. The obtained values were tabulated against their respective parameters and then interpreted for the study. Avergae sacral index in females (109) is significantly greater than males (94). As per present study sacral index can reliably identify 58% of male sacrum and 42% of female sacrum. It is therefore a quite reliable and significant criteria for sex determination of sacrum. Thus, regional and racial differences in sacrum along with sacral index can be used for anatomical, medico-legal and anthropological purposes.

Published: July 2020

Pseudomonas aeruginosa is one among the leading nosocomial pathogens worldwide. It is therefore necessary to decrease and to prevent a rebound of growth. Comparison of novel suspension testing method and agar cup diffusion method results in determination of the sensitive method to identify effectiveness of disinfectants against microbial activity. This study was carried out to determine the effectiveness among novel suspension testing and agar cup diffusion method to determine disinfectant susceptibility and also to identify the efficacy of ethanol and chlorhexidine gluconate at manufacturer’s concentration against Pseudomonas aeruginosa. In this study 50 isolates of Pseudomonas aeruginosa were included. Each isolate was subjected to novel suspension testing method and agar cup diffusion method with ethanol and chlorhexidine gluconate, the results were observed and recorded. The 50 isolates, sensitive strains showed 100% sensitivity to chlorhexidine gluconate and 95% to ethanol. Whereas resistant strains showed 100% sensitivity to chlorhexidine gluconate, 75% were sensitive to ethanol. Both agar cup diffusion method and novel suspension method yielded similar results. With the advantage of easy processing and less time consumption, agar cup diffusion method can be routinely used for determining the disinfectant susceptibility testing.
Beneficial effects of long term caloric vestibular stimulation on changes in brain neurotransmitter dopamine and locomotor activity in Parkinson’s Disease induced rats
Authors: Thanalakshmi J  , Archana R  , Senthil Kumar S
Published: July 2020

Parkinson's Disease (PD) is a neurodegenerative disorder caused due to deficiency of Dopamine in the Substantia nigra. The existing pharmaceutical treatments are not meeting the need, whereas deep brain stimulation is not suitable for patients with co-morbidities. Therefore, a need for non-invasive and conventional treatment with fewer side effects is required. So we have tried a simple method of Caloric Vestibular Stimulation (CVS) for the long term and assessed its neuroprotective effect in PD induced rats. In the present study, 30 adult male Wistar albino rats (250 - 300g) were randomly assigned into five groups. Group 1 control, Group 2 was induced with Parkinson’s disease using rotenone, Group 3 was PD induced and CVS gave for 45 days, Group 4 was PD induced for 21 days and left untreated to study for its recovery, Group 5 was given CVS only for 45 days. The behavioral activity was recorded using an actophotometer and to assess the function of the nigrostriatal pathway. Dopamine produced in the striatum was measured using reverse-phase HPLC. Results showed significant (P< 0.05) alteration in dopamine and locomotor activity in PD, which was significantly (P< 0.05) improved by warm water CVS administration in Parkinson's disease-induced rat. In this aspect, CVS can be utilized as a conventional treatment method for PD and thus recommended for further investigations towards translational treatment in humans for Parkinson’s disease.

Published: July 2020

Citizens’ political participation and engagement on various social media handles have made it necessary for scholars to investigate and understand the potentials inherent in the political engagement and discourse of individual citizens. Hence, the study examined Twitter discourse on the 2019 pre-presidential election campaign in Nigeria. Purposive sampling technique with thematic textual research method was used to thematically analyse tweets based on the research questions. Findings from the study showed that the kind of engagement made or done by Nigerians regarding the 2019 pre-presidential election campaigns was based on the topic, with most topics being met with sarcasm. The sarcasm found in the tweets pointed to the way Nigerians react in a situation that they have no way of rectifying. Also, findings from the study showed that celebrity tweet gets more engagement compared to tweets made by unpopular tweeps. Conclusively, the study found that the level of discourse on Twitter regarding Nigeria’s 2019 pre-presidential elections was very rich and participatory this implies that Nigerians have a high propensity to relate on social media as their rate of responses as well as their frequency of responses remained high throughout the election campaign period which to a large extent predicts real-life events.
Virtual Reality and Situated Experiential Education A conceptualisation and exploratory trial
Authors: Schott Christian , Marshall Stephen
Published: July 2020

Virtual reality is widely recognised as
offering the potential for fully immersive environments. This paper describes a
framework that guides the creation and analysis of immersive environments that
are pedagogically structured to support situated and experiential education.
The “situated experiential education environment” framework described in this
paper is used to examine the impact that a virtual environment can have on the
user experience of participants in a virtual space. The analysis of a virtual
environment implemented to support learner exploration of issues of tourism
development and the related impacts suggests that this type of experience is
capable of providing participants with a holistic experience of real world
environments that are otherwise too expensive, impractical or unethical for
large groups of people to visit in person. The pedagogical value of such
experiences is enabled through immersion in a reality-based environment,
engagement with complex and ambiguous situations and information, and
interaction with the space, other students and teachers. The results demonstrate
that complex immersive learning environments are readily achievable but that
high levels of interactivity remains a challenge.

Teaching second languages for the workplace
Authors: Newton Jonathan , Kusmierczyk E
Published: July 2020

Workplace culture and organization are evolving as they adapt to globalization and rapid technological development. Likewise, the nature and role of workplace language and the literacy demands of work are changing in the face of increasingly multicultural workplaces and global communication networks. Among these changes, recent research has highlighted the role that informal modes of interpersonal communication play in the functioning of the modern workplace. Successful participation in such interactions is seen as not just a question of fitting in socially, but of doing work through talk. Ethnographic research in the workplace has stressed the importance of understanding language by viewing it within its social setting and understanding the interactional norms of particular communities of practice. Research into language programs for the workplace reflects this shift in emphasis. In contrast to research in the field of language for specific purposes on the specialized vocabulary and formal registers of particular professions, a growing body of research focuses on teaching and learning the language of routine workplace interactions. This article reviews current research into the nature of workplace language, noting in particular the contributions from ethnographic and language socialization research. It then discusses research into four aspects of the content of language programs for the workplace: employability skills, interpersonal communication, intercultural and critical language awareness, and teaching focused on the employment interview. © Cambridge University Press, 2011.

Published: July 2020

Sometimes we need to minimize the conditions of topology for different reasons such as obtaining more convenient structures to describe some real-life problems, or constructing some counterexamples whom show the interrelations between certain topological concepts, or preserving some properties under fewer conditions of those on topology. To contribute this research area, in this paper, we establish some new concepts on supra topological spaces using supra semi-open sets and give some characterizations of them. First, we introduce a concept of supra semi limit points of a set and study main properties, in particular, on the spaces that possess the difference property. Second, we define and investigate new separation axioms, namely supra semi Ti-spaces (i = 0, 1, 2, 3, 4) and give complete descriptions for each one of them. We provide some examples to show the relationships between them as well as with STi-space.

The sandstones at the base of the Honda Group (La Victoria Formation - Early Miocene), in the Dina Field, Upper Magdalena Valley Basin (UMVB) – Colombia, which are present in the analyzed interval of the Dina Norte 27 and Dina Norte 37 wells, are composed of immature clastic rocks classified as Litharenites / Feldspathic Litharenites, due to the presence of volcanic fragments, feldspar / plagioclase and unstable minerals.They are texturally immature due to poor selection and low roundness of the detritus. The following sequence of diagenetic processes is proposed: minor compaction; grain coating by illite/smectite detritical clay, dissolution of unstable minerals, zeolite (heulandite) precipitation, partial precipitation of nonferroan calcite cement and finally chloritization of clays prior to hydrocarbon migration.

Authors: Tellez- Gutierrez Sandra Milena , Duarte Velasco Oscar German , Rosero García Javier
Published: July 2020

This paper sets out features of traditional Energy Key Performance Indicators (KPIs) employed in energy management programs; then, new indicators are proposed based on Advanced Metering Infrastructure (AMI) usage. These indicators make it possible to directly relate the amount of energy, type of end use and user consumption patterns. Analysis of AMI system information enables planning for differentiated Demand-Side Management (DSM) strategies. A case study developed at Universidad Nacional de Colombia - Bogotá campus is presented, which proposes new Energy Key Performance Indicators in Real Time. These indicators enable information analysis and DSM strategies that are appropriate for new technologies and that are aimed at increasing energy efficiency. Additionally, this paper presents the factors that have to be taken into account when implementing KPIs (Key Performance Indicators) and the decision-making process. This results in variable overall energy savings between 5 and 40%, according to the DSM strategy implemented.
Analysis of the covariance matrix in FWI through density of covariance maps
Authors: Jimenez Anyeres Neider , Muñoz Cuartas Juan Carlos , Avendaño Sheryl , Gómez Bernal Leonardo
Published: July 2020

Full waveform inversion (FWI) is a tool for the inversion of seismic data. There are several sources of uncertainty in the results provided by FWI. The quantification of such uncertainties has been studied through the resolution matrix (Res), which rests on a quadratic approximation that interprets the Hessian matrix as the posterior covariance matrix. Despite efforts in the use of Res, there is no published analysis of the uncertainties contained in the full correlation matrix, (R). Our approach leads to build the full R matrix, which, at the end of the day, is the final quantity that includes all the information associated with uncertainties.We focused on uncertainties related to variation in the starting models of the FWI, and thus propose a method to study the full R matrix, which is-called the Density of Correlation Map, D. By using the D map, we found that the highest uncertainty zones in the FWI inverted model are near the sources, the model boundaries, and the interfaces. We argue that D can be a complement for the study and estimation of uncertainties in FWI.

Cheating among college students has long been a concern in the academic field. In addressing this problem, it is imperative to determine in what circumstances college students cheat. Looking into the internal factor, previous research found that the depletion of self-control increased the probability of cheating. To determine whether this result could be replicated in an Indonesian population, we conducted an experimental study. A sample of 63 undergraduates was randomized into two groups, a self-control depletion group (had difficult essay-writing task) and a self-control no-depletion group (had an easy essay-writing task). After writing the essay, the participants were then asked to complete a knowledge task directly on the test sheet and then copy their answers into a pre-marked sheet. Cheating was determined as modified answers from the test sheet to the pre-marked sheet. The results showed a significant difference in modified answers between the depleted and non-depleted self-control group (t = 2.09, p < 0.05). This finding indicates that depletion of self-control affects cheating. This study has a meaningful implication for determining the ideal setting in which the university should conduct their examinations.
A Model Penyesuaian Diri Mahasiswa Baru
Authors: Jamaluddin Muhammad
Published: July 2020

Salah satu tugas kehidupan seseorang secara psikologis itu diantaranya adalah harus mampu melakukan penyesuaian diri secara terus menerus dengan lingkungan dan perkembangan yang ada. Penyesuaian diri ini sangatlah dibutuhkan oleh setiap individu terutama pada individu yang sedang menginjak masa remaja, karena jika permasalahan penyesuaian diri ini tidak teratasi dengan baik, maka akan menimbulkan masalah-masalah baru dalam kehidupannya. Adapun dari penelitian ini didapatkan hasil adanya problematika penyesuaian diri yang meliputi aspek psikologis, akademis, sosial dan demografis. Sementara penyelesaian atas permasalahan atau problematika penyesuaian diri ini diantaranya melalui aspek internal (yakni dengan cara individu atau mahasiswa tersebut membuat goal setting, manajemen diri ataupun berinteraksi social dengan baik) dan eksternal (adanya kebutuhan terhadap pendampingan psikologis dan konseling dari lembaga).

Tujuan penelitian ini adalah untuk mengetahui hubungan antara self regulated learning, self-esteem, dukungan sosial dengan flow akademik pada siswa Program SKS dan Program Reguler. Penelitian ini merupakan jenis penelitian kuantitatif korelasional. Alat pengumpulan data dalam penelitian ini menggunakan skala seelf regulated learning, skala self esteem, skala dukungan sosial, dan skala flow akademik. Subjek dalam penelitian ini berjumlah 85 dari total populasi 890 siswa MAN 2 Kota Probolinggo melalui teknik menggunakan penelitian populasi dan quota sampling. Metode yang digunakan dalam penelitian ini adalah metode kuantitatif dengan teknik analisis berganda. Hasil penelitian menujukkan nilai F hitung = 38.874 dengan signifikansi 0.000 < 0.05, Hal ini menunjukkan bahwa hubungan self regulated learning, self-esteem, dan dukungan sosial secara bersama flow akademik pada siswa program sks dan program reguler, terdapat hubungan yang signifikan. Sehingga hipotesis yang diajukan diterima, artinya semakin tinggi self regulated learning, self-esteem, dukungan sosial yang dimiliki, maka akan semakin tinggi pula flow akademik yang dirasakan.

POLOXAMER 407 GEL FOR TOPICAL ADMINISTRATION: INFLUENCE OF ACETIC ACID AND DEMINERALIZED WATER ON THE BEHAVIOR OF THE GEL OBTAINED
Authors: Li Dally , Gja Lia , A N'guessan , Any-Grah Aka , A Tuo , C N'guessan , Aa Koffi
Published: July 2020

Background: Poloxamers are low-toxicity copolymers whose aqueous solutions can pass reversibly from the ground state to the gel state at temperatures approaching body temperature, which is of interest for their use as a reservoir system of active principle. Understand the effect of the type of solvent on the rheological characteristics of the gel obtained.

Methods: Various formulations of Poloxamer 407 gel at 16% and 17,5% were prepared and evaluated successively in acetic acid and demineralised water. The main evaluation parameters were the gelling temperature (T gel) and the concentration of these different solvents.

Results: The T (gel) at 16% F127 in demineralised water and 0.1M acetic acid was 27º ± 0.3 and 17.5% at 25º to 29ºC ± 0.1. in 0.1M and 16 % acetic acid, there is no marked gelation. At 17.5% F127 in acetic acid, gelationwas observed and the Tgel was higher than with F127 in deionized water.

Conclusion: The gelation process is favored by increasing the concentration of  F127 and is substantially disadvantaged by 0.1M acetic acid.
THE CAUSAL LINK BETWEEN VACCINATION ADJUVANTS AND AUTISM
Authors: Prevenslik Thomas
Published: July 2020

Adjuvants essential in vaccines to stimulate activation of the immune system comprise submicron (< 100 nm) nanoparticles (NPs) of aluminum hydroxide that upon vaccine injection cross the blood-brain-barrier (BBB) and because of their low solubility may remain in the brain for an extended time. Despite over a century of use, the mechanism underlying the stimulation of the immune system by adjuvants has not been understood. Solar UV can optically stimulate most immune systems in the skin, but solar UV is not available inside the brain. By the process of simple QED, the NPs lacking heat capacity by the Planck law conserve heat from brain tissue by emitting UV radiation instead of increasing in temperature. Hence, the causal link between vaccination adjuvants and autism is UV stimulation of the immune system from constituent NPs that cross the BBB. But the UV also damages the DNA of brain tissue and increases the pro-inflammatory interleukin (IL-6) cytokine levels common in autism patients. Pre-vaccination enzyme-linked immunosorbent assay (ELISA) tests of IL-6 level including UV blood irradiation (UBI common in immune-modulating therapy are suggested to determine if a patient will have an adverse vaccination response. Patients having high IL-6 levels are not recommended for vaccination.

Authors: Michael Tomy
Published: July 2020

Pulau Sentinel sebagai pulau yang memiliki kompleksitas permasalahan hukum seperti adanya izin dari Pemerintah India untuk mengunjunginya dan larangan untuk mengunjungi di sekitarnya. Penelitian ini dilakukan dengan metode penelitian metode pendekatan empiris yuridis, yaitu dimana penulis mencari, menggali, dan menemukan fakta-fakta serta kenyataan yang ada di dalam masyarakat dengan melihat situasi dan kondisi yang terjadi. Di dalam perspektif UNCLOS 1982, pulau buatan tidak diperinci secara detail karena pulau masih menganut pemahaman akan ekonomis padahal pulau buatan untuk saat ini adalah suatu kebutuhan di suatu negara. Keleluasaan ini secara tertulis diatur dalam Pasal 87 UNCLOS 1982 dimana laut lepas terbuka untuk semua Negara, baik Negara pantai atau tidak berpantai. Sebagai kesimpulannya Pulau Sentinel termasuk pulau alami yang tidak berpenghuni. Pemberian pulau alami dikarenakan pulau ini ada dan tidak merupakan pulau buatan dalam perspektif UNCLOS 1982. Sementara pemberian nama pulau tidak berpenghuninya karena adanya larangan dari Pemerintah India dengan argumen tidak menghuni untuk menjaga keberlangsungan hidup dari suku asli tersebut.
