This study aims to analyze various difficulties in learning the character of elementary school students in the online / digital era and their solutions through the use of video media. This research uses descriptive studies with a qualitative approach. The data sources in this study are elementary school teachers and parents of students related to the character learning process. Data collection was carried out through observation and in-depth interviews with informants; Teachers and Students. Data analysis is carried out by reduction, display and conclusion. The results showed that character learning problems carried out online were not able to stimulate emotional and motor aspects, so that children were less enthusiastic. Lack of proper media to teach the attitudes or behaviors of elementary school children who still like to play. Therefore, videos with certain characters and well presented can arouse children's attention and stimulate their behavior to learn more enthusiastically. Therefore, it is necessary to make and present videos that contain educational values to direct the behavior of elementary school students in learning so that they can change for the better. In this case, videos that are filled with educational values can be one of the character learning media in online learning for elementary school students.
A STUDY ON RISK ADJUSTED PERFORMANCE OF OPEN-ENDED EQUITY MID CAP AND MULTI – CAP MUTUAL FUND SCHEMES IN INDIA BY SHARPE RATIO : PRE COVID SCENARIO
Authors: Daliwala Noel 
Published: May 2024

Mutual funds are risky financial instruments, they are governed by the normal risks involved in investments. It is difficult to predict the performance of a mutual fund just on the basis of the return of the fund. The performance can only be evaluated in a correct manner if the risk is considered in evaluating the return. Hence a mutual fund's performance is accurate only if it is risk-adjusted performance.
In this study, 21 Open Ended Multi Cap Funds and 17 Open Ended Mid Cap funds are compared using the Sharpe Model by William F. Sharpe, who developed it in 1966. The data of 10 calendar years of pre covid is taken for the period between 1st January 2009 – 31st December, 2019. The S&P BSE SENSEX is taken as the benchmark index under this study. It was found that most of the funds had outperformed the market and given good returns.

Authors: Santos Rafaela Melo , Almeida Edson Vinicius Santos , Fagundes Naiara Lima , Pires Laila Eduarda Silva , Ladeia Luiz Eduardo de Góes 
Published: May 2024

Aims: Understand the relationship between bisphosphonates used in the treatment of osteoporosis and mandibular osteonecrosis, its outcomes, and implications for patient management, seeking to understand the best strategies for preventing and managing this condition.
Study Design: Integrative literature review.
Methodology: The research methodology was outlined as exploratory and qualitative, aiming to provide a deeper understanding of the problem under study and generate hypotheses. Works published in the last 10 years (2014 to 2024) were used, including books, articles, periodicals, and online resources. For the selection of the sample, priority was given to works indexed in national and international journals, available in full. The electronic search was conducted in databases such as Latin American and Caribbean Health Sciences Literature (LILACS), Medical Literature Analysis and Retrieval System Online (MEDLINE), and Scientific Electronic Library Online (SciELO). The descriptors used were "Antiresorptive", "Bisphosphonate", "Mandible" and "Bone necrosis", registered in the Health Sciences Descriptors (DeCS), combined with the Boolean operators "AND" and "OR". The inclusion criteria for the selection of articles were to be original, addressing the theme of the study, to be indexed in the selected databases, written in Portuguese or English, and to be free of charge. Studies that were not related to the theme, duplicates and that did not fit into the proposed analysis period were excluded.
Results: Through the studies surveyed, an association between the incidence of osteonecrosis and the use of osteoporosis drugs, such as bisphosphonates, especially osteonecrosis of the jaws (ONJ), was observed. Bisphosphonates, widely used in the treatment of osteoporosis, inhibit bone resorption, but their long-term use is associated with complications, including ONJ. Risk factors such as advanced age, long-term use of medications, comorbidities such as diabetes, and genetic predisposition have been identified.
Conclusion: Management of ONJ involves conservative therapies and surgical procedures, which are especially effective when the condition is diagnosed early. On the other hand, therapeutic alternatives, such as photodynamic therapy, are being investigated, highlighting the need for controlled clinical trials to determine their efficacy.
Energy Materials: Layered LaSrGa3O7‐Based Oxide‐Ion Conductors: Cooperative Transport Mechanisms and Flexible Structures (Adv. Funct. Mater. 22/2010)
Authors: Tealdi Cristina , Mustarelli Piercarlo , Islam M. Saiful 
Published: November 2010

AbstractNovel melilite‐type gallium‐oxides are attracting attention as promising new oxide‐ion conductors with potential use in clean energy devices such as solid oxide fuel cells. Here, an atomic‐scale investigation of the LaSrGa3O7‐based system using advanced simulation techniques provides valuable insights into the defect chemistry and oxide ion conduction mechanisms, and includes comparison with the available experimental data. The simulation model reproduces the observed complex structure composed of layers of corner‐sharing GaO4 tetrahedra. A major finding is the first indication that oxide‐ion conduction in La1.54Sr0.46Ga3O7.27 occurs through an interstitialcy or cooperative‐type mechanism involving the concerted knock‐on motion of interstitial and lattice oxide ions. A key feature for the transport mechanism and high ionic conductivity is the intrinsic flexibility of the structure, which allows considerable local relaxation and changes in Ga coordination.

Authors: Walker Michael J. , Ortega Jon , López Mariano V. , Parmová Klára , Trinkaus Erik 
Published: November 2010

AbstractThe Sima de las Palomas, southeastern Spain, has yielded a series of Neandertal postcranial remains, including immature and mature isolated elements and the fragmentary partial skeleton of a young adult (Palomas 92). The remains largely conform to the general late archaic/Neandertal morphological pattern in terms of humeral diaphyseal shape, pectoralis major tuberosity size and pillar thickness, ulnar coronoid process height, manual middle phalangeal epiphyseal breadth, manual distal phalangeal tuberosity shape and breadth, femoral diaphyseal shape, and probably body proportions. Palomas 92 contrasts with the Neandertals in having variably gracile hand remains, a more sellar trapezial metacarpal 1 facet, more anteroposteriorly expanded mid‐proximal femoral diaphysis, and less robust pedal proximal phalanges. The Palomas Neandertals contrast with more northern European Neandertals particularly in various reflections of overall body size. Am J Phys Anthropol, 2011. © 2010 Wiley‐Liss, Inc.

Authors: Röglin Lars , Lempens Edith H. M. , Meijer E. W. 
Published: November 2010

AbstractDendrimere haben eine Reihe einzigartiger Eigenschaften, die sie zu interessanten Architekturen für biomedizinische Anwendungen machen. Bisher wurden multivalente und multimodale dendritische Strukturen überwiegend durch die statistische Modifikation der Endgruppen hergestellt. Ihre potenzielle Anwendung am Patienten verlangt dagegen nach wohldefinierten, monodispersen Materialien mit einer einheitlichen Struktur. Aktuelle Fortschritte in der chemischen Biologie und bei chemoselektiven Ligationsmethoden ermöglichen es nun, sich dieser Herausforderung zu stellen. In diesem Kurzaufsatz diskutieren wir die unterschiedlichen Synthesestrategien, einige Anwendungen, die diese neue Generation multivalenter und multimodaler Architekturen bereits nutzen, und die Herausforderungen für zukünftige Weiterentwicklungen.
Swelling study of superabsorbent PAA‐co‐PAM/clay nanohydrogel
Authors: Patra Subrata K. , Swain Sarat K. 
Published: November 2010

AbstractA series of superabsorbent composites were prepared from acrylic acid (AA), acrylamide (AM), and Cloisite® 30B by aqueous solution polymerization technique using ammonium peroxodisulfate (APS) as initiator. The interaction of the organically modified nanoclay with PAA‐co‐PAM copolymer was verified by FTIR, whereas the morphology of the composite was studied by Scanning Electron Microscopy (SEM). The water absorbency in deionized water and saline water of the synthesized nanohydrogels was measured by calculating their percentage swelling ratio. The effects of copolymerization, monomer ratio, clay content, and temperature on the water absorbency were studied. The results indicated a considerable increase in swelling ratio by proper monomer proportion and incorporation of optimum clay percentage into the copolymer matrix. It was found that the nanohydrogel acquired highest water absorbency with 2% clay loading. The reswelling ability and water retention capacity of the PAA‐co‐PAM hydrogel and PAA‐co‐PAM/clay nanohydrogel were also measured. The water absorbency was found to increase after each reswelling for which it may be useful as recyclable superabsorbent material. The results of water retention capacity of the nanohydrogel were also encouraging and find application in agriculture, especially in drought‐prone areas. © 2010 Wiley Periodicals, Inc.

Biosynthesis and degradation of the endocannabinoid 2‐arachidonoylglycerol
Authors: Ueda Natsuo , Tsuboi Kazuhito , Uyama Toru , Ohnishi Taira 
Published: November 2010

Abstract2‐Arachidonoylglycerol (2‐AG) is a monoacylglycerol (MAG) molecule containing an esterified arachidonic acid chain at sn‐2 position of the glycerol backbone. Together with structurally similar N‐arachidonoylethanolamine (anandamide), 2‐AG has been extensively studied as an endogenous ligand of cannabinoid receptors (an endocannabinoid) in brain and other mammalian tissues. Accumulating evidence demonstrates that the endocannabinoid system, including the central‐type cannabinoid receptor CB1 and 2‐AG, is responsible for synaptic retrograde signaling in the central nervous system. As 2‐AG is rapidly formed from membrane phospholipids on cellular stimuli and degraded to arachidonic acid and glycerol, the enzymes catalyzing its biosynthesis and degradation are believed to play crucial roles in the regulation of its tissue levels. The major biosynthetic pathway appears to consist of sequential hydrolyses of inositol phospholipids via diacylglycerol (DAG) by β‐type phospholipase C and DAG lipase, while MAG lipase is a principal enzyme in the degradation. In this short review, we will briefly outline rapid advances in enzymological research on the biosynthetic and degradative pathways of 2‐AG.

Published: November 2010

AbstractMonoclinic BiVO4crystals with preferentially exposed (040) facets were hydrothermally synthesized by using a trace amount of TiCl3as the directing agent; this function was confirmed by X‐ray diffraction patterns (XRD) and high‐resolution transmission electron microscopy (HRTEM). The effects of the directing agent TiCl3and the pH values applied during synthesis have been studied, and the optimized BiVO4sample with highly exposed (040) facet could be obtained by using 1.2 at. % of TiCl3as the directing agent at a pH value of 2. Some complementary techniques were also applied to exclude the effects of the structural and physical property changes, such as surface area and hydrophilicity. The photocatalytic activity of oxygen evolution on BiVO4is found to be proportionally correlated with the exposed surfaces of the (040) facet. It is assumed that the active sites with a BiV4structure on the exposed (040) facet is assigned to be responsible for the high activity of O2evolution.
Structural Effects of Fe3O4 Nanocrystals on Peroxidase‐Like Activity

Published: November 2010

AbstractThe catalytic activity of nanocrystal catalysts depends strongly on their structures. Herein, we report three distinct structures of Fe3O4 nanocrystals, cluster spheres, octahedra, and triangular plates, prepared by a similar hydrothermal procedure. Additionally, the three Fe3O4 nanostructures were used as peroxidase nanomimetics and the correlation between the catalytic activities and the structures was first explored by using 3,3′,5,5′‐tetramethylbenzidine and H2O2 as peroxidase substrates. The results showed that the peroxidase‐like activities of the Fe3O4 nanocrystals were structure dependent and followed the order cluster spheres>triangular plates>octahedra; this order was closely related to their preferential exposure of catalytically active iron atoms or crystal planes. Such investigation is of great significance for peroxidase nanomimetics with enhanced activity and utilization.
Use of standard markers and incorporation of molecular markers into breast cancer therapy
Authors: Kaufmann Manfred , Pusztai Lajos ,   the Biedenkopf Expert Panel Members
Published: November 2010

AbstractBreast cancer is a heterogeneous disease of different subtypes on the molecular, histopathological, and clinical level. Genomic profiling techniques have led to several prognostic and predictive gene signatures of breast cancer that may further refine outcome prediction, especially in clinically equivocal situations. In particular, the predictive value of today's most important therapeutic targets, ER and HER2, are strongly influenced by the proliferative status of the tumor. Genomic assays are generally performed in a centralized manner, whereas routine pathological evaluation is mostly done on a decentralized basis, making the comparison of these methods difficult. Thus, there remains considerable uncertainty about the use of the new molecular markers in routine clinical decision making and their role in patient selection or stratification for future clinical trials. To address this concern, a group of representatives from breast cancer research groups in the areas of breast pathology, genomic profiling, and clinical trials critically reviewed all available data. Consensus recommendations are made on the practical use of molecular markers in breast cancer management and their incorporation into future clinical trials.

Published: November 2010

AbstractBACKGROUND:The impact of FMS‐like tyrosine kinase 3 (FLT3) mutations and mutation burden among cytogenetic subgroups of patients with acute myeloid leukemia (AML) other than normal karyotype (NK) AML is unclear.METHODS:Patients with newly diagnosed AML were divided among 3 cytogenetic subgroups: core binding factor (CBF) AML, NK‐AML, and poor‐risk AML.RESULTS:In total, 481 patients were included: 13% had, CBF‐AML, 57% had NK‐AML, and 30% had poor risk AML, and the frequency of any FLT3 mutations was 20%, 32%, and 7.6% in the respective cytogenetic subgroups. FLT3 mutation did not have an impact on event‐free survival (EFS) in patients with CBF‐AML (P = .84) and poor‐risk AML (P = .37). In patients with NK‐AML, EFS was worse in the FLT3‐internal tandem duplication (ITD) group (20 weeks vs 41 weeks; P < .00,001) but not in the FLT3‐tyrosine kinase domain (TKD) point mutation group (61 weeks vs 41 weeks; P = .15). Worse EFS and overall survival (OS) were observed among patients with NK‐AML and higher FLT3‐ITD burden but not among patients with FLT3‐TKD mutation. In multivariate analysis, FLT3‐ITD mutation was prognostic of EFS in patients with NK‐AML (hazard ratio, 3.1; P = .03).CONCLUSIONS:FLT3 mutations did not have a prognostic impact in patients with AML who had good‐risk and poor‐risk karyotypes. In patients with NK‐AML, FLT3‐ITD mutations led to worse survival, which was even worse among patients who had high mutation burden. Cancer 2011. © 2010 American Cancer Society.

Published: November 2010

AbstractBACKGROUND:Several sirtuin family members (SIRT1‐7), which are evolutionarily conserved NAD‐dependent deacetylases, play an important role in carcinogenesis. However, their role in oral cancer has not yet been investigated. Therefore, the objective of this study was to investigate whether sirtuins play a role in oral cancer carcinogenesis.METHODS:The expression levels of all sirtuins in several oral squamous cell carcinoma (OSCC) cell lines were compared with normal human oral keratinocytes and observed that SIRT3 was highly expressed. Therefore, tissue microarrays were used to evaluate the clinical relevance of this overexpression. SIRT3 down‐regulation in OSCC cell proliferation and survival was investigated and analyzed by using cell‐proliferation and cell‐viability assays. Ionizing radiation and cisplatin were used to investigate whether SIRT3 down‐regulation could increase the sensitivity of OSCC to both treatments. To further assess the in vivo role of SIRT3 in OSCC carcinogenesis, a floor‐of‐mouth oral cancer murine model was used to study the effect of SIRT3 down‐regulation on OSCC tumor growth in immunodeficient mice.RESULTS:The current results demonstrated for the first time that SIRT3 is overexpressed in OSCC in vitro and in vivo compared with other sirtuins. Down‐regulation of SIRT3 inhibited OSCC cell growth and proliferation and increased OSCC cell sensitivity to radiation and cisplatin treatments in vitro. SIRT3 down‐regulation also reduced tumor burden in vivo.CONCLUSIONS:The current investigation revealed a novel role for SIRT3 in oral cancer carcinogenesis as a promoter of cell proliferation and survival, thus implicating SIRT3 as a new potential therapeutic target to treat oral cancer.

Authors: Hsieh Susan Gyea‐Su , Hibbert Sally , Shaw Peter , Ahern Verity , Arora Manish 
Published: November 2010

AbstractBACKGROUND:The aim of this study was to examine the effect of antineoplastic therapy on dental development and saliva function in recipients of childhood antineoplastic therapy.METHODS:Patients attending the long‐term follow‐up clinic at Children's Hospital at Westmead, NSW, Australia, were included if they had received treatment prior to 16 years of age and were in remission for more than 5 years. A dental examination and saliva test were performed for each participant. Holtta's Defect Index (HDI) was used to assess tooth aplasia, microdontia, and root‐crown ratio on an orthopantomogram (OPG). Multivariable‐adjusted regression analyses were used to estimate the association of patient characteristics and treatment modalities with dental outcomes.RESULTS:One hundred six participants (61% male) were recruited (response rate = 88%). The mean HDI score was 24.7 ± 17.8. A cumulative dose of cyclophosphamide >7500 mg/m2 increased the HDI score by 13.06 (P = .01). Recipients of cyclophosphamide also had significantly increased odds of exhibiting very low saliva flow (<0.7 mL/min) (odds ratio = 12.43; 95% confidence interval, 2.08‐74.35; P = .006).CONCLUSIONS:Children and adolescents who received high doses of cyclophosphamide were at increased risk of dental disturbances. Cyclophosphamide recipients were also at greater risk of exhibiting very low saliva flow. This study applied the HDI to patients receiving all forms of antineoplastic treatment and highlights the dose‐dependent relation between cumulative dose of cyclophosphamide and dental disturbances.
