Authors: Patil Natasha , Maheshwari Neha , Sharma Rohit , Soni Shashank , Kushwah Ashish
Published: April 2020

Introduction: Skeletal maturity indicators are very important indicators when diagnosing and panning the treatment in growing population. Cervical Vertebrae Method (CVM) and Fishman’s Skeletal Maturity Indicators are two commonly used methods for the diagnosis and treatment planning. The aim of the study was to investigate the correlation between cervical vertebral maturation (CVM)and Fishman’s hand-wrist skeletal maturity indicator and chronological age by including subjects within the range of circumpubertal growth spurt in Central India.

Materials & Method: One Twenty Five contemporary hand-wrist and lateral cephalometric radiographs from population of Central India were randomly selected and analyzed. All subjects were within the circumpubertal period i.e. female subjects were between 10 and 15 years of age, and the male subjects were between 12 and 17 years of age. The hand-wrist bone analysis was evaluated using the method developed by Fishman whereas cervical vertebra bone analysis was evaluated using the method developed by Baccetti and co-workers. These two methods and chronological age were correlated using the Spearman rank correlation analysis.

Result: CVM was significantly correlated with hand-wrist maturation (r=0.8868). However low correlation was found between the CVM and chronological age( r =0.7139) and little correlation was found between the HWM and chronological age ( r =0.6892).

Conclusion: CVM is a valid indicator of skeletal growth during the circumpubertal growth period and has a high correlation with the HWM for the Central India population. However chronological age is not suitable to measure skeletal maturity as shown by the low correlations found between the chronological age and both CVM and HWM.

Published: April 2020

Concern about allergic reactions in orthodontic patients has been expressed regularly. Patients undergoing orthodontic treatment with fixed appliances are exposed to various biomaterials. Awareness of reactions that can occur with these dental materials is important to the orthodontist. The aim of this paper is to review the current literature on allergy in orthodontics and the implications of the allergic reaction in the management of patients during orthodontic treatment. Diagnosis and treatment should include a multidisciplinary team. In all instances, the patient’s well-being should guide treatment decisions, and general health not just oral health should be the goal.

The clinical and instrumental examination and polysomnographic examination were carried out in 94 patients with chronic brain ischemia on the background of venous cerebral dysfunction with concomitant pathology-chronic obstructive pulmonary disease. 21 (22.3%) patients from the subjects had clinical manifestations of obstructive sleep apnea/hypopnea syndrome: mild – in 3, moderate – in 11, severe – in 7. A significant correlation between the body mass index, the number of episodes of apnea and the level of saturation of hemoglobin with oxygen, symptoms of venous cerebral dysfunction is shown. There was no correlation with the forced expiratory volume index for the 1st s. It should be assumed that in the pathogenesis of obstructive apnea/hypopnea syndrome in chronic obstructive pulmonary disease, the degree of obesity and venous cerebral dysfunction, rather than the severity of lower respiratory tract obstruction, are more important.

Published: April 2020

There is a new public health crisis threatening the world with the emergence and spread of 2019 novel
coronavirus (2019-nCoV). Due to the specialty of oral healthcare settings, the risk of cross infection is
severe among patients and oral healthcare practitioners as they work in close proximity to their patients
employing droplet and aerosol generating procedures. The transmission modes of SARS-coronavirus appear
to be through droplet spread and close contact. Although the principle of universal precautions is widely
advocated and followed throughout the dental community, it is not sufficient to help control the spread of
this highly contagious disease. Management protocols must be modified to minimize public health risks.
This includes the identification, isolation, management and report of possible and probable cases and
contacts. Patient assessment should include questions on recent travel to infected areas and, contacts of
patients, fever and symptoms of respiratory infections. Hence, there is a need for strict and efficient infection
control protocols as the patient may be symptomatic as well as asymptomatic.

Authors: Hu Liming , Zhou Fuyou , Li Hongxia , Herman James G , Hu Liming , Guo Mingzhou , He Tao
Published: April 2020

Background: The function of TMEM176A in human lung cancer remains to be elucidated.
Materials & Methods: Nine cell lines and 123 cases of lung cancers were employed.
Results: TMEM176A was highly expressed in H727 cells, reduced expression was observed in A549, H446
and H460 cells, loss of expression was found in H157, H1563, H358, H1299 and H23 cells. TMEM176A
was unmethylated in H727 cells, partially methylated in A549, H446 and H460 cells, and fully methylated
in H157, H1563, H358, H1299 and H23 cells. Loss of/reduced expression of TMEM176A is correlated to
promoter region methylation. Restoration of TMEM176A expression was induced by 5-AZA-2-
deoxycytidine in complete methylated cells, increased expression of TMEM176A was observed in partially
methylated cells. These results suggest that TMEM176A is regulated by promoter region methylation in
lung cancer cells. TMEM176A was methylated in 53.66% (66/123) of non-small cell lung cancers
(NSCLCs) samples. Reduced expression of TMEM176A was associated with promoter region methylation
in 40 cases of matched primary NSCLCs and adjacent tissue samples (P<0.05). TMEM176A expression
induced cell apoptosis, inhibited colony formation, cell proliferation, migration and invasion.
Conclusion: Methylation of TMEM176A activated ERK signaling in lung cancer cells. TMEM176A
suppressed human lung cancer cell xenograft growth in mice.

Authors: Abdul-Kahar Adam  , Nasser Salim Al Saadi  , Dr. Ebi Shahrin Bin Suleiman
Published: April 2020

This is theoretically basic research with conceptual studies theories to establish the importance of work culture in an organisation. Work Culture is seen as the behaviours, attitudes, commitments and staff performance are key in advancing towards orgnisational objectives. Work Culture have direct correlation with job satisfaction and good governance and that is if organisations really want to grow their business. Job satisfaction on the other hand states that both extrinsic and intrinsic factors such as the salary increment and employees’ welfare are paramount to the hearts of staff. Moreover, good governance demands that the following principles must be put into practice namely accountability, integrity, compliance, trustworthy, discipline, ethical leadership, efficiency and effectiveness, and participation. In the methodology, a random sample of 40 public bus drivers were interviewed with their responses used to generate data for analysis in SmartPLS. The results indicated that all the three (3) variable constructs are valid and reliable. The Cronbach Alpha for Job Satisfaction, Good Governance, and Work Culture was 0.7, 0.8, and 0.7 consecutively. According to Hair et al., (2007) argued that a Cronbach alpha value of 0.6 and above means there is high reliability. This was a quantitative research study. This conceptual research showed that in the transport industry especially the public sector more attention must be paid to these three variables in order to achieve objectives namely good governance, job satisfaction and work culture to improve the human resource management practices in the public transportation industry.

The impact of globalization has caused the inevitable challenges which demands education to emphasis on developing students holistically in both cognitive and non-cognitive aspects of learning. The United Nations 2030 Agenda for Sustainable Development Goals (SDG) promotes the role of education in promoting sustainable development. Goal 4 in SDG: “Ensure inclusive and equitable quality education and promote lifelong learning opportunities for all” and its corresponding targets. Target 4.7 in SDG 4 emphasis on values education to develop students to be responsible citizens locally and globally. Nurturing global citizenship among students is crucial to ensure students are well equipped with appropriate skills, and being responsible and responsive to the local and global issues. However, students show moderate level of students’ knowledge, skills, and attitudes on global citizenship. The Middle Years Programme International Baccalaureatte (MYPIB) was introduced by Ministry of Education Malaysia in 2013 to develop students holistically through the development of International Baccalaureatte Learner Profile. The implementation of the MYPIB in International Baccalauretae World (IB) School Kementerian Pendidikan Malaysia has succeeded in nurturing International Baccalaureate (IB) Learning Profile among IBWS KPM students, thus, simultaneously promoting global citizenship among them.

Authors: Singh Meljev
Published: April 2020

This paper will review and discuss the presence of healthcare facilities in Melaka while it was under Portuguese rule from 1511 to-1641. The presence of healthcare facilities, while recorded, has not been studied in detail. While most of Portuguese Melaka was destroyed by the Dutch bombardment of 1641, some of the healthcare facilities that existed in the city were recorded even though they were eventually destroyed by the Dutch as they took over the city. This paper will record some of these institutions and detail the type of healthcare provided. Here, Portuguese records will be reviewed and evidence of hospitals will be elaborated upon. This paper will rely solely on historical writings by modern scholars and where possible, ancient Portuguese records. This paper aims to enable us to better understand the role of hospitals in the city of Melaka and why the Portuguese emphasized building them from an early period.
Dysembryoplastic neuroepithelial tumor presenting as a hypothalamic hamartoma in a child with gelastic seizures: case report
Authors: Cai Yuxiang , Wang Yanjin , Yang Zhiquan
Published: April 2020

Dysembryoplastic neuroepithelial tumors (DNETs) are benign intracranial tumors of neuroglial origin, mostly located in the supratentorial regions and particularly in the temporal lobe. Few cases of DNETs in the hypothalamus have been described. The authors present the case of a DNET in the hypothalamus. The 5-year-old girl with complaints of limb and gelastic seizures was admitted to the neurosurgical department of Xiangya Hospital. Neurological examination findings were unremarkable. MRI showed isointensity without significant enhancement on T1- and T2-weighted images. The lesion exhibited clearly defined borders on the sagittal, coronal, and axial images. The preliminary diagnosis was hypothalamic hamartoma (HH); however, the lesion was surgically removed, and histopathological examination confirmed the diagnosis of a DNET. Hypothalamic DNETs are extremely rare. Based on their clinical manifestation and imaging, DNETs are easily misdiagnosed as HHs. Diagnoses apart from HHs must be entertained when a hypothalamic lesion is being investigated.

Reinforcement learning for personalization: A systematic literature review
Authors: den Hengst Floris , Grua Eoin Martino , el Hassouni Ali , Hoogendoorn Mark
Published: April 2020

The major application areas of reinforcement learning (RL) have traditionally been game playing and continuous control. In recent years, however, RL has been increasingly applied in systems that interact with humans. RL can personalize digital systems to make them more relevant to individual users. Challenges in personalization settings may be different from challenges found in traditional application areas of RL. An overview of work that uses RL for personalization, however, is lacking. In this work, we introduce a framework of personalization settings and use it in a systematic literature review. Besides setting, we review solutions and evaluation strategies. Results show that RL has been increasingly applied to personalization problems and realistic evaluations have become more prevalent. RL has become sufficiently robust to apply in contexts that involve humans and the field as a whole is growing. However, it seems not to be maturing: the ratios of studies that include a comparison or a realistic evaluation are not showing upward trends and the vast majority of algorithms are used only once. This review can be used to find related work across domains, provides insights into the state of the field and identifies opportunities for future work.

Published: April 2020

This paper aims to exhibit of optimal location and capacity of energy storage (ES) in electricity development planning, including transmission expansion planning (TEP) and generation expansion planning (GEP). Renewable energy sources are being developed in the world in order to replace the increasingly exhausting and polluting fossil energy sources. However, the energy generation of these types cannot be intentionally controlled but depends on natural conditions. To support the defects that renewable energy causes, energy storage systems have been studied and applied. Developing energy storage to charge cheap energy and provide higher prices in the electricity market is one of the issues that have being attention recently. Although choosing the proper location to place is a great challenge. A number of algorithms have been researched for a long time to find suitable locations for GEP; heuristic algorithms have been used in recent years because of their flexibility and wide range. The heuristic approaches, although being varied over time to become more and more effective search engines, but the problem is withheld into local extremes during searching, the number of too many loops when applied to large network systems... are still being researched and overcome by scientists for heuristic algorithms. On the other hand, the Max-Flow-Min-Cut (MFMC) algorithm has been applied to determine thyristor controlled series compensation (TCSC) to manage congestion that also has been of interest to many researchers but it has some limitations. The MFMC algorithm will be improved more effectively to eliminate congestion collaborate with a heuristic in the paper, and the simulation results tested to determine the position and power of ES on the 24 bus IEEE system showed the algorithm's feasibility.

Método: Trata-se de um estudo retrospectivo e descritivo onde foram pesquisados 348 prontuários de pacientes com diagnostico de câncer de próstata no Instituto Maranhense de Oncologia Aldenora Bello. As variáveis pesquisadas foram: faixa etária; procedência; ocupação; antígeno prostático especifico inicial; escore de Gleason da biopsia; escore de Gleason da peça cirúrgica (em pacientes cujas terapêuticas incluíram prostatectomia radical ou ressecção transuretral de próstata); e tratamento instituído. Resultados: A faixa etária mais acometida foi de 71 a 80 anos (39,7%). A maior parte dos pacientes era procedente de São Luís - MA (64,1%) e não possuía ocupação (55,2%). A maioria dos pacientes (32,8%) apresentou antígeno prostático especifico inicial entre 4,1 e 10 ng/ml. O Gleason da biopsia revelou, em 48,5% dos casos, tumores moderados a fracamente diferenciados. A terapêutica predominante foi composta de tratamento clinico e/ou orquiectomia subcapsular bilateral. Conclusão: O presente estudo demonstrou uma associação significativa do antígeno prostático especifico com a faixa etária e o Gleason, revelando maior tendência de aumento dos seus níveis quanto maior a idade e maior a graduação histológica dos tumores. Do total dos pacientes, 36,5% obtiveram escores de Gleason da biopsia e peca cirúrgica equivalentes.
A educação como arma contra o obscurantismo
Authors: Mata Vilson Aparecido da
Published: April 2020

O texto aqui apresentado fez uma análise do modo pelo qual se constituiu um projeto educacional para a sociedade burguesa em seus primórdios. Esse projeto era fundamental na luta pela efetivação da nova sociedade, que procurava superar o obscurantismo medieval por meio, entre outros, da formação de indivíduos com conhecimentos de rudimentos das ciências e, para tanto, era preciso aprender a ler, fazer operações matemáticas e conhecer as leis da natureza. Para a burguesia ascendente, o conhecimento científico foi instrumento para a formação de pessoas capazes de melhor se conduzirem em meio às novas relações sociais, negando as antigas instituições feudais e fundando as novas instituições burguesas. Desse modo, foram resgatados aspectos do pensamento de Marx, Engels, John Locke, Jean-Jacques Rousseau, Michel de Montaigne e Condorcet. Entre os elementos abordados que deram forma à linha de reflexão para este artigo, o caráter histórico da educação, o processo de mudanças imanente à formação humana e a perspectiva de que a educação transformadora deve compor um projeto de sociedade foram definidos como fulcrais ao melhor entendimento da constituição da educação burguesa como instrumento de transformação da sociedade. A conclusão apontou para a mudança na abordagem da educação, pela burguesia, conforme mudou também sua posição histórica: como classe social revolucionária, a educação compunha um projeto de transformação, porém, uma vez sedimentada a sociedade capitalista burguesa, a educação tornou-se conservadora e dedicada à formação e qualificação profissional, despida de seus elementos transformadores.

Attempt was made towards optimizing an in vitro shoot multiplication of banana cultivar Gopi with subsequent assessment of genetic stability. Experiments on enhanced shoot multiplication were conducted in MS fortified with BAP, Kn and 2-iP (4 mg/l) for a period of 8 weeks. Administration of exogenous root inducing growth regulator was eliminated to reduce culture investment and economy. Treatment with BAP supplemented medium proved to be optimum for shoot multiplication whereas 2-iP produced satisfactory results for shoot elongation. Long term incubation in all the treatments had been favorable for developing efficient root system. Hardening of in vitro grown plantlets showed high rate of survival (95%) upon transfer to potted soil. Assessment of clonal fidelity through inter simple sequence repeats (ISSR) analysis revealed 100% uniformity.

Embryogenic callus was obtained from the leaf explants of jojoba (Simmondsia chinensis (Link) Schneider cultured on MS containing 0.5 mg/l NAA and 0.5 mg/l Kn. Growth of embryonic callus increased in 0.5 mg/l Kn + 6% sucrose. In order to improve oil content, the embryonic callus was exposed to different doses (5, 10 and 15 Kr) of gamma radiation. It was found that oil content of embryonic callus of jojoba increased 1.41% by exposing to 5 Kr gamma radiation. Also, size of oil bodies in embryonic callus irradiated with 5 Kr increased compared to control. Furthermore, production of the fatty acids was enhanced by gamma irradiation. The highest percentage of total fixed oil (1.41) was recorded in 5 Kr radiation. However, the highest content of total fatty acids (98.612) was obtained when embryonic callus were exposed to 10 Kr of gamma radiation.

Published: April 2020

Alteration of cellular components and host physiology due to five biotypes of Cucumber mosaic virus (CMV) were investigated to know the effects on ultimate growth and yield of chilli. Severe reduction of cellular components like chlorophyll-a (59.31%), chlorophyll-b (68.40%), total chlorophyll (63.20%) and β-carotene (51.14%) were observed in plant infected by mosaic and stunting (MoS) as compared to healthy plant. The ratio of RNA to DNA was increased in the infected leaves. The reduction of photosynthesis rate was found 6.32 to 17.10% in CMV infected plants as compared to healthy plants. Stomatal conductance and inter cellular CO2 was found lower in CMV infected plats. Considerable yield reduction (28.80 to 78.11%.) was found infected with five symptomatic isolate of CMV. The present findings indicate that multiplication of virus particles in the infected cells alter the biochemical compounds of cells that disrupt the physiological process which affect the growth and yield of chilli.

Published: April 2020

The experiment was conducted to assess five tropical strawberry genotypes at phenotypic and molecular level. Among the five strawberry genotypes (BARI Strawberry 1, BARI Strawberry 2, BARI Strawberry 3, FA 005 and Festival), BARI Strawberry 2 was found to be the best in respect of fruit per plant (32.42), fruit yield per plant (594.73 gm) and yield per hectare (19.39 ton). Ten SSR primers were initially screened for molecular characterization and finally MFv104, ARSFL-10 and ARSFL-15 markers were selected for the analysis. EMFv104 and ARSFL-15 produced the maximum number of polymorphic alleles (4) while ARSFL-10 produced three polymorphic alleles. The major allele frequency at each locus ranged from 0.4 (EMFv104) to 0.6 (ARSFL-10). The PIC values varied from 0.4992 on ARSFL-10 to 0.672 on EMFv104. The gene diversity ranged from 0.56 (ARSFL-10) to 0.72 (EMFv104 and ARSFL-15). BARI Strawberry 1 and Festival were the closest genotypes with the lowest genetic dissimilarity value of 0.16667. EMFv104 and ARSFL-15 can be used as polymorphic markers for assessing genetic diversity of different strawberry genotypes.

The study aims at developing the valid Contextual Teaching-Learning (CTL) Approach-based audio visual learning media in order to improve the learning motivation and the critical thinking skills significantly and also at identifying the effectiveness level of the Contextual Teaching-Learning (CTL) Approach-based audio visual learning media in improving the students’ learning motivation and critical thinking skills. Therefore, autoatically the nature of the study is research and development. During the conduct of the study, the data were gathered by using the random sampling technique. Then, the data gathering instruments that had been implemented were the media assessment questionnaire, the observation, the motivation questionnaire and the critical thinking skills test. The results of the study show that the Contextual Teaching-Learning (CTL) Approach-based audio-visual learning media that has been developed by using the Borg & Gall model is considered valid. The students’ learning motivation has increased as having been confirmed by the fact that the students are more enthusiastic, more interested and happier in attending to the learning process. Furthermore, the results of the students’ critical thinking skills test in the experimental group show that 25 students have met the passing grade while the remaining 6 students have not met the passing grade. On the other hand, the results of the students’ critical thinking skills test in the control group show that 20 students have met the passing grade while the remaining 12 students have not met the passing grade. In other words, these findings show that the learning process through the use of the Contextual Teaching-Learning (CTL) Approach-based audio-visual learning media is able to improve the students’ learning motivation and critical thinking skills.

Recently, we derived “humanized” spontaneously hypertensive rats (SHR-CRP) in which transgenic expression of human CRP induces inflammation, oxidative stress, several features of metabolic syndrome and target organ injury. In addition, we found that rosuvastatin treatment of SHR-CRP transgenic rats can protect against pro-inflammatory effects of human CRP and also reduce cardiac inflammation and oxidative damage. In the current study, we tested the effects of rosuvastatin (5 mg/kg) on kidney injury in SHR-CRP males versus untreated SHR-CRP and SHR controls. All rats were fed a high sucrose diet. In SHR-CRP transgenic rats, treatment with rosuvastatin for 10 weeks, compared to untreated transgenic rats and SHR controls, was associated with significantly reduced systemic inflammation which was accompanied with activation of antioxidative enzymes in the kidney, lower renal fat accumulation, and with amelioration of histopathological changes in the kidney. These findings provide evidence that, in the presence of high CRP levels, rosuvastatin exhibits significant anti-inflammatory, anti-oxidative, and renoprotective effects.

Cigarette smoking is a risk factor for many diseases. It could be associated with sarcopenia. The aim of this meta-analysis was to determine whether smoking is an isolated risk factor for sarcopenia. We searched PubMed, Web of Science, EBSCO, and Science Direct for articles addressing the relationship between cigarette smoking and sarcopenia. A total of 12 studies containing information on 22,515 participants were included in this meta-analysis. Odds ratio (OR) was calculated for each study group and for all studies together. An OR was also calculated separately for each sex. We used a fixed-effect model in overall estimation and in males, because results of small studies were significantly different from the results of large studies in those cases and in females where the estimation showed only moderate heterogeneity we used a random-effect model. According to proposes of the Cochrane Handbook for Systematic Reviews. The resulting OR in the fixed-effect model was 1.12 (95 % CI 1.03-1.21), OR for each sex was in the fixed-effect model 1.20 (95 % CI 1.06-1.35) in males and in the random-effect model 1.21 (95 % CI 0.92-1.59) in females. The results of this meta-analysis indicate that cigarette smoking as an isolated factor may contribute to the development of sarcopenia. However, the results of the individual studies were largely inconsistent due to different approaches of measuring the main variables which affected the results.
