Published: September 2017

We have studied the relative positions of the frontier levels determine the main electronic properties and reaction ability, there is important necessity to compare the MO of the purine and рyrimidine bases: adenine (A), guanine (G), cytosine (C), thymine (T) and uracil (U). The donor and acceptor properties are the fundamental characteristic of the conjugated molecules and can be quantitatively estimated by relative positions of the frontier molecular orbitals. The MO’s energies can be estimated experimentally or quantum-chemically. Analysis of the relative position of the frontier levels (calibrated by the energy gap) enables the investigation of the donor/acceptor properties of the RNA/DNA bases more detailed. The index φ0 is proposed for the quantitative quantum-chemical estimation of the donor ability of the conjugated molecules: it points on the shifting of the energy gap relative to the reference electron balanced system. The RNA/DNA bases divided strictly by two groups: predominantly donors (φ0 > 0.5) and predominantly acceptors (φ0 > 0.5). Each representative base of the first group forms the stable base pair the representative base of the second group the difference of indices Δφ0 should be optimal to enables the DNA replication.

A marine fibrinolytic compound FGFC1 enhancing fibrinolysis was obtained involving in enzymatic kinetic parameters of reciprocal activation system with single chain urokinase type plasminogen activator and plasminogen. FGFC1, a kind of bisindole alkaloid from a metabolite of rare marine fungi Starchbotrys longispora FG216, modulated enzymatic kinetic parameters including fibrinolytic reaction rate and fibrin degradation characteristics. The enzymatic kinetics of fibrinolysis was described based on enzymatic reaction of chromogenic-substrate associated with p-nitroaniline (p-NA). While single chain urokinase-type plasminogen activator (pro-uPA) actived plasminogen, Kcat and kcat/km increased significantly with increase of FGFC1 concentration. Moreover, Kcat and kcat/km exhibited 26.5-fold and 22.8-fold enhanced activity at the concentration of 40 μg•mL−1 of FGFC1, respectively. The results suggested that FGFC1 improved significantly the maximum catalytic efficiency and the total catalytic activity of fibrinolysis base on the reciprocal activation of pro-uPA and plasminogen. Km increased with increasing FGFC1 concentration, which indicated that FGFC1 decreased slightly the affinity activity of pro-uPA and plasminogen versus enzyme substrate. The marine bisindole alkaloid FGFC1 enhanced fibrinolysis which was taken on enzymatic kinetic characteristics.

Ensaios de Velocidade de Propagação de Pulso Ultrassônico (VPU) são cada vez mais usados para detectar falhas em concreto. Este trabalho é parte de um programa experimental amplo que buscou estudar a influência de variáveis-chave na capacidade de detecção usando ensaios de VPU em elementos de escala natural. Para essa investigação foram moldados dois elementos de concreto de larga escala, com vários objetos introduzidos em um deles para simular possíveis falhas de concretagem. Ademais, para verificar a capacidade de identificação de vazios não-aparentes com a técnica de VPU, perfurações graduais em diferentes profundidades foram feitas a partir da face não monitorada. Os resultados confirmam que o ensaio de VPU é uma ferramenta adequada para detecção de falhas no concreto, até certa profundidade.

Authors: Vila Patricia , Pereyra María Noel , Gutiérrez Álvaro
Published: September 2017

Con el objetivo de validar el ensayo de resistencia a la compresión en medio adoquín para el control de calidad, se analizaron experimentalmente adoquines enteros y medios adoquines en un total de 24 lotes de producción. El resultado en adoquín entero fue mayor que en medio adoquín, siendo posible relacionarlos mediante un factor de forma. Si bien el estudio se limitó a un rango de resistencia y a una única forma y espesor, se comprobó que es posible ensayar medio adoquín para el control de calidad de estos elementos. Esto permitiría utilizar la otra mitad para otro ensayo, simplificando los controles de obra con una menor cantidad de adoquines y la posibilidad de utilizar prensas de menor capacidad.

Authors: Ma Yifei , He Shaohui , Liu Tielong , Yang Xinghai , Zhao Jian , Yu Hongyu , Feng Jiaojiao , Xu Wei , Xiao Jianru
Published: October 2017

Background:

Patients with spinal metastasis from cancer of unknown primary origin have limited life expectancy and poor quality of life. Surgery and radiation therapy remain the main treatment options, but, to our knowledge, there are limited data concerning quality-of-life improvement after surgery and radiation therapy and even fewer data on whether surgical intervention would affect quality of life.

Methods:

Patients were enrolled between January 2009 and January 2014 at the Changzheng Hospital, Shanghai, People’s Republic of China. The quality of life of 2 patient groups (one group that underwent surgery followed by postoperative radiation therapy and one group that underwent radiation therapy only) was assessed by the Functional Assessment of Cancer Therapy-General (FACT-G) questionnaire during a 6-month period. A subgroup analysis of quality of life was performed to compare different surgical strategies in the surgical group.

Results:

A total of 287 patients, including 191 patients in the group that underwent surgery and 96 patients in the group that underwent radiation therapy only, were enrolled in the prospective study; 177 patients completed all 5 checkpoints and 110 patients had died by the final checkpoint. The surgery group had significantly higher adjusted quality-of-life scores than the radiation therapy group in each domain of the FACT-G questionnaire (all p < 0.05). Subgroup analysis showed that adjusted functional and physical well-being scores were higher in the circumferential surgical decompression group.

Conclusions:

Surgery followed by postoperative radiation therapy improved and maintained quality of life in patients with spinal metastasis from cancer of unknown primary origin in the 6-month assessment. In terms of surgical strategies, circumferential decompression seems better than laminectomy alone in quality-of-life improvement.

Blood Conservation Using Tranexamic Acid Is Not Superior to Epsilon-Aminocaproic Acid After Total Knee Arthroplasty
Authors: Boese Clifford Kent , Centeno Leslie , Walters Ryan W.
Published: October 2017

Background:

Epsilon-aminocaproic acid (EACA) and tranexamic acid (TXA) are synthetic amino acid derivatives that interfere with fibrinolysis, promoting hemostasis by pharmacological means. Although both drugs have been shown to decrease blood loss with a minimal risk of thromboembolic adverse events following cardiac and vascular surgery, we are aware of only 1 published trial that directly compared the antifibrinolytic effects of EACA with those of TXA after total knee arthroplasty (TKA). The primary aim of this prospective, randomized, controlled trial was to determine whether TXA provides superior blood conservation following TKA compared with that provided by EACA.

Methods:

A total of 194 patients scheduled to undergo a primary unilateral TKA in the same community-based hospital were prospectively randomized to receive intravenous EACA (n = 96) or TXA (n = 98). Both the patients and the operating surgeons were blinded to the treatment assignments. Primary outcome measures included transfusions, estimated blood loss, and the drop in the hemoglobin (Hgb) level. Secondary outcomes measures included the change in the serum creatinine level, postoperative complications, and length of hospital stay.

Results:

Although the patients who received TXA averaged less estimated blood loss than the patients who received EACA (t185 = 2.18, p = 0.031; mean difference = 144.2 mL, 95% confidence interval = 13.62 to 274.78 mL), no transfusions were required in either group. We observed no statistically significant or clinically relevant between-group differences in the change in Hgb or serum creatinine level, postoperative complications, or length of hospital stay.

Conclusions:

Although the estimated blood loss was significantly greater in the EACA group, no transfusions were required and no significant between-group differences were observed for any other outcomes measured. We concluded that EACA may be an acceptable alternative to TXA for blood conservation following TKA, although replication of our results in noninferiority trials is necessary.

Limiar de eficiência em avaliações de tecnologias em saúde
Authors: Saad Ricardo , Lemmer Teresa , Clark Otávio
Published: October 2017

Limiares de custo-efetividade (CE) têm sido foco de discussão em relação à necessidade de um limiar fixo para a realidade brasileira, em particular do Sistema Único de Saúde (SUS). Frequentemente é referido o uso desse tipo de limiares em outros países, porém, estes variam significativamente e muitos são implícitos. Os limiares de CE se baseiam em resultados incrementais (ICERs), incluindo frequentemente medidas de anos de vida ajustados pela qualidade (QALY) e, assim, estão estritamente atrelados às limitações destes. Têm sido propostas alternativas ao uso desses limiares de CE, entre estes o limiar de eficiência, método utilizado pelo governo alemão para determinar valores máximos de reembolso de novas tecnologias inseridas em seu sistema de saúde. Para cada área terapêutica é traçado um gráfico de benefício vs. custo incremental das tecnologias já incorporadas. As opções com maior CE são conectadas formando o limiar de eficiência, permitindo a avaliação de novas intervenções. Este artigo revisa as características, limitações e alternativas aos limiares de CE e propõe uma temática que vá além da atual discussão sobre a adequação ou não do estabelecimento de um limiar fixo para o Brasil.
Literature Review of Saccharomyces boulardii in the Treatment of Refractory Recurrent Clostridium difficile Infection
Authors: Warila Rachel , Hoover Rebecca
Published: September 2017

Objective: To evaluate the efficacy of S. boulardii for the treatment of recurrent C. difficile infections.

Methods: Eligible articles included S. boulardii in patients with recurrent C. difficile infection. The primary endpoint examined was clinical resolution of infection with no further recurrences during follow-up.

Results: Six studies met inclusion criteria. A case report showed resolution of recurrences in one patient, and an experimental trial showed a trend towards decreased recurrences in patients receiving S. boulardii (85% no further recurrences). Two randomized controlled trials found a significant decrease in recurrences for S. boulardii versus placebo (34.6% vs 64.7%, P=0.04; 16.7% vs 50%, P=0.05). One meta-analysis determined significant efficacy for S. boulardii in reducing relapses (RR 0.59, 95% CI 0.35-0.98), while another concluded there was insufficient evidence to recommend probiotics for C. difficile infection.

Conclusions: S. boulardii may be considered for patients with recurrent C. difficile infection, refractory to antibiotic regimens alone.

Assessment of climate change impact on rainfall for studying water availability in upper Mahanadi catchment, India
Authors: Jaiswal R. K. , Tiwari H. L. , Lohani A. K.
Published: October 2017

The paper deals with the projected rainfall for eight rain gauge stations located in the upper Mahanadi catchment in Chhattisgarh state of India and corresponding changes on the water availability in few reservoirs of the catchment. Rescaled predictors obtained from NCEP were used and statistically tested for selection of best-fit set of predictors using percentage reduction methods. The calibrated and validated models were used to generate multiple series for early, mid and late century periods, i.e. for 2020–2035 (FP-1), 2046–2064 (FP-2) and 2081–2099 (FP-3) under CMIP5 climatic forcing conditions of RCP2.6, RCP4.5 and RCP8.5 using predictors data of CanESM2, Canadian GCM. The comparisons of future predicted rainfall with the base period (1981–2003) showed mixed trends, viz. declining trend at five stations, both declining and increasing trend at two stations, and increasing trend at one station. The predicted reduced rainfall during August and September attribute to a significant impact on paddy cultivation and industrial development. The analysis of future catchment rainfall on five important reservoirs in this region indicated a reduction of 12–29% seasonal rainfall with respect to the base period rainfall; while for one reservoir not much variation (–7 to 5%) in the rainfall was noted, possibly due to the large catchment area.

Authors: Hanief Aslam , Laursen Andrew E.
Published: October 2017

The Grand River watershed (GRW) is an important agricultural area in Southern Ontario. Land use has been modified by various human endeavors, altering hydrology and increasing export of sediment and nutrients. The objective of this study was to predict spatial and temporal patterns of hydrology, and export of sediment and nutrients from the GRW to Lake Erie using the Soil and Water Assessment Tool (SWAT) model. The Sequential Uncertainty FItting (SUFI2) program was used to calibrate and validate stream flow for years 2001–2010. Calibration and validation of the SWAT model for monthly stream flow at York indicated good model performance (R2, NSE, and PBIAS = 0.64, 0.63 and 7.1 for calibration (2001–2005); = 0.82, 0.74 and 0.2, for validation (2006–2010)). The model was applied to predict sediment and nutrient export from the GRW into Lake Erie. Predicted loading at Dunnville (near the mouth) was 2.3 × 105 tonnes y−1 total suspended sediment, 7.9 × 103 tonnes y−1 TN, and 2.3 × 102 tonnes y−1 TP. This SWAT model can now be used to investigate the relative effects of best management practices, and to forecast effects of climate change, on sustainable water management, hydrology, and sediment and nutrient export to Lake Erie.

Published: September 2017

Small-scale irrigation continues to cushion the food security gap in sub-Saharan Africa. Irrigation is largely governed by water availability, soil type and crop water requirements, among other factors. Thus, a study was conducted to assess the suitability of various water sources for irrigation in northern Ghana. Specifically, the study sought to assess quality of water sources in the Savelugu, Kasena-Nankana East, and Nabdam districts for small-scale irrigation development. The water quality parameters used were: pH, electrical conductivity (ECw), sodium adsorption ratio (SAR), sodium percent (Na%), soluble sodium percentage (SSP), magnesium adsorption ratio (MAR), Kelley's ratio (KR), total hardness (TH), chloride (Cl), Escherichia coli, and fecal coliforms. While we found most of the irrigation water sources, including small reservoirs, dams, wells and rivers suitable, few unsuitable irrigation water sources were also identified. Overall, the study found that opportunities for scaling small-scale irrigation exist in all the sites. The knowledge generated from this study will guide irrigation water use, and agricultural policy for sustainable smallholder irrigation development in the region.
Developing Social Media-Based Suicide Prevention Messages in Partnership With Young People: Exploratory Study
Authors: Robinson Jo , Bailey Eleanor , Hetrick Sarah , Paix Steve , O'Donnell Matt , Cox Georgina , Ftanou Maria , Skehan Jaelea
Published: October 2017

Background

Social media is increasingly being used by young people for health-related issues, including communicating about suicide. Due to the concerns about causing distress or inducing suicidal thoughts or behaviors, to date young people neither have been engaged in the development of social media–based suicide prevention interventions nor have interventions focused on educating young people about safe ways to communicate about suicide online. Given the potential that social media holds to deliver messages to vast numbers of people across space and time and the fact that young people often prefer to seek help from their friends and peers, safely educating and engaging young people to develop suicide prevention messages that can be delivered via social media is an obvious next step.

Objectives

The objectives of this study were to (1) provide education to a small number of secondary school students about safe ways to communicate about suicide via social media; (2) engage the same young people in the development of a suite of social media–based suicide prevention multimedia messages; (3) assess the impact of this on participants; and (4) assess the acceptability and safety of the messages developed.

Methods

This study involved two phases. In phase 1, 20 participants recruited from two schools took part in an 8- to 10-week program during which they were provided with psychoeducation about mental health and suicide, including how to talk safely about suicide online, and they were then supported to design and develop their own media messages. These participants completed an evaluation questionnaire at the conclusion of the program. In phase 2, a larger group of participants (n=69), recruited via an opt-in process, viewed the media messages and completed a short questionnaire about each one.

Results

Participants in phase 1 enjoyed the program and reported that they learned new skills, such as how to talk safely about suicide online, and felt more able to provide emotional support to others (16/20, 80%). No participants reported that the program made them feel suicidal. Participants in phase 2 generally rated the media messages as safe and acceptable, although some messages were rated more highly than others.

Conclusions

This study suggests that young people can be safely engaged in developing suicide prevention messages, which can be disseminated via social media. Engaging young people in this process may improve the traction that such campaigns will have with other young people. The study also suggests that educating young people regarding how to talk safely about suicide online has multiple benefits and is not associated with distress. Overall, these findings pave the way for new approaches to prevent suicide among young people.
Integrated Hepatitis C Care for People Who Inject Drugs (Heplink): Protocol for a Feasibility Study in Primary Care (Preprint)
Authors: McCombe Geoff , Swan Davina , O’Connor Eileen , Avramovic Gordana , Vickerman Peter , Ward Zoe , Surey Julian , Macías Juan , Lambert John S , Cullen Walter
Published: October 2017

BACKGROUND

Hepatitis C virus (HCV) infection is a major cause of chronic liver disease and death. Drug use remains the significant cause of new infections in the European Union, with estimates of HCV antibody prevalence among people who inject drugs ranging from 5% to 90% in 29 European countries. In Ireland and the European Union, primary care is a key area to focus efforts to enhance HCV diagnosis and treatment among people who inject drugs.

OBJECTIVE

The Heplink study aims to improve HCV care outcomes among opiate substitution therapy (OST) patients in general practice by developing an integrated model of HCV care and evaluating its feasibility, acceptability, and likely efficacy.

METHODS

The integrated model of care comprises education of community practitioners, outreach of an HCV-trained nurse into general practitioner (GP) practices, and enhanced access of patients to community-based evaluation of their HCV disease (including a novel approach to diagnosis, that is, Echosens FibroScan Mini 430). A total of 24 OST-prescribing GP practices were recruited from the professional networks and databases of members of the research consortium. Patients were eligible if they are aged ≥18 years, on OST, and attend the practice for any reason during the recruitment period. Baseline data on HCV care processes and outcomes were extracted from the clinical records of participating patients.

RESULTS

This study is ongoing and has the potential to make an important impact on patient care and provide high-quality evidence to help GPs make important decisions on HCV testing and onward referral.

CONCLUSIONS

A substantial proportion of HCV-positive patients on OST in general practice are not engaged with specialist hospital services but qualify for direct-acting antiviral drugs treatment. The Heplink model has the potential to reduce HCV-related morbidity and mortality.

Globalization, National Identity and Foreign Policy: Understanding 'Global Korea'
Authors: John Jojin V.
Published: October 2017

One of the striking themes in contemporary South Korean foreign policy is a strong emphasis on achieving seonjinguk (advanced nation) status in international affairs, as articulated in the slogan 'Global Korea'. Engaging with the discourse of globalization, the concept of seonjinguk has provided Korea with an interpretive framework for discussions of its national identity and global position. The historical experience of Korea as a hujinguk (backward country) underlies the emphasis accorded to the goal of becoming seonjinguk. The article argues that the discursive practice of Global Korea was not merely a point of departure in Korean foreign policy but was also the key site of Korean national identity construction. Through an exploration of the historical context and diplomatic practice of constructing Global Korea, it illustrates the continuity and authority of the discourse of seonjinguk in interpreting and constructing Korean national identity.
The Inflow of Southeast Asian Healthcare Worker Candidates in Japan:Japanese Reactions to the Possibility of Cultural and Ethnic Diversity
Authors: Kaneko Kenji
Published: October 2017

This paper examines the social and cultural meanings of the incorporation of Southeast Asian healthcare migrant workers in Japan, focusing in particular on Japanese attitudes and perspectives. I argue that several issues and concerns are related to the way the Japanese see Japan as a homogeneous society, and that these issues and concerns intertwine with Japan's historical experience of the inflow of non-Japanese migrants. The arrival of Southeast Asian healthcare workers has been met with concern in Japanese society, but because of its rapidly aging and shrinking population, Japan's healthcare industry needs to internationalize. The article is based on research data that includes information on events, debates and arguments in official and unofficial documents, newspaper articles and transcripts of interviews in the press in both Japanese and English. It aims to provide a better understanding of how Japan is tapping into the international labour market to bolster its health industry. The situation of Southeast Asian healthcare migrant workers in Japan is also examined in its historical, social and cultural contexts.

Authors: Soares CJ , Rosatto CMP , Carvalho VF , Bicalho AA , Henriques JCG , Faria-e-Silva AL
Published: October 2017

Objectives:

To compare radiopacity and porosity as expressed by the presence of voids in restorations carried out using bulk-fill and incremental filling techniques to restore large mesio-occlusal-distal (MOD) cavities.

Methods:

Fifty-five molars with MOD preparations were incrementally filled with Filtek Z-350XT (Z350XT) or bulk-fill composite: Filtek Bulk Fill/Z-350XT (FBF/Z350XT), Venus Bulk Fill/Charisma Diamond (VBF/CHA), SDR/Esthet-X HD (SDR/EST-X), Tetric EvoCeram Bulk Fill (TEC). Digital radiographic images (Vistascan scanner) were taken of restored molars and analyzed at the gingival and isthmus floors. Radiodensity measurements were performed using standardized points symmetrically distributed over each region of composite and tooth structure. Three calibrated evaluators visually assessed the presence of voids. Confidence intervals were calculated, and data were analyzed using analysis of variance and χ2 tests.

Results:

TEC and VBF/CHA showed significantly higher radiodensities, while the lowest values were observed for FBF/Z350XT and Z350XT. Radiodensity at the cervical regions tended to be greater than that found at the isthmus floor. The lowest incidence of voids was found for VBF/CHA, whereas the incremental insertion technique resulted in the highest rate of voids.

Conclusion:

Bulk-fill composite resin demonstrated an adequate level of radiodensity and a reduced presence of voids compared with the incremental filling technique.

LA ENSEÑANZA DE LA GEOGRAFÍA Y LA FORMACIÓN GEOGRÁFICA EN LOS ESTUDIOS UNIVERSITARIOS DE MAESTRO
Authors: Martínez Fernández Luis Carlos
Published: September 2017

Siguiendo lo enunciado por Wartofsky (1983, p. 23), parece oportuno “analizar o delimitar las funciones, los modos de actividad y los procedimientos típicos de la ciencia con respecto a los fines o propósitos que sirve”. Con este trabajo se plantea una reflexión acerca del interés y sentido que la enseñanza de la Geografía, en cuanto disciplina académica construida en torno a un cuerpo sistematizado de conceptos, conocimientos y metodologías, tiene en relación a la formación universitaria de los futuros maestros. Y ello en un contexto, el actual, en el que la situación de la Geografía en los nuevos títulos de Magisterio o Educación puede ser calificada de verdadero arrinconamiento disciplinar, como lo demuestra la consulta efectuada a todas y cada una de las asignaturas y encargos docentes de las titulaciones existentes en las universidades públicas de España. Se trata de pensar, en última instancia, una propuesta con la que dotar de coherencia a la docencia que desde las áreas de conocimiento de Geografía se imparte en los Grados en Educación Primaria.
ASPECTOS A CONSIDERAR FRENTE AL CONCEPTO DE INTELIGENCIA EN NIÑOS PRIVADOS SOCIOCULTURALMENTE: LA IMPORTANCIA DE LAS EVALUACIONES DINÁMICAS
Authors: Cabezas Corcione Andrés
Published: September 2017

El constructo inteligencia se ha utilizado principalmente para medir la capacidad que tienen los individuos de resolver un problema, correlacionando el cociente intelectual con el rendimiento escolar. Esto ha generado una visión estática y poco modificable de ciertas habilidades cognitivas, con resultados poco favorables en niños de contextos rurales o deprivados socioculturalmente, evidenciando el impacto de la cultura en las diferencias  individuales. En primera instancia, se realiza un breve barrido histórico sobre el concepto inteligencia, para luego señalar alcances y limitaciones de la medición del cociente intelectual, discutiendo el concepto de retardo mental sociocultural que no busca afirmar una etiología cultural, sino comprender y resaltar la importancia del contexto y las diferencias individuales en las habilidades cognitivas. Finalmente se concluye que la inteligencia y su medición deben cumplir con el objetivo de identificar fortalezas y no sólo déficits en el rendimiento escolar, enfatizando la aplicación de mediciones positivas dinámicas.

The wound healing process of the soft tissue aims to accelerate the closing of the wound by recurring, restoring the function, and minimizing the scar tissue. This process has to occur in the surgery process to obtain better-wound healing. The aim of this study was to know the stimulation effect of the wound dressing to accelerate the wound healing process of the soft tissue using Collagen (amino acid) and Amnion (proteinase inhibitors). This true experimental study was done to 36 mice (Sprague Dawley) that were divided into three different groups, two groups were the treatment groups and one group was the control group. Each group was adapted in Pathology Laboratory of Faculty of Veterinary Medicine Bogor Agricultural University. All of the mice were injured on the skin by incising the right side of the back for 2 cm in length and 4 mm in depth and then cleaned with 0.9% NaCl solution. To the first group of treatment, the wound was applicated by Amnion, and the second group was applicated by Collagen. Each 4 mice of all group were a termination by ether and encryption on the wounded tissue was conducted on day 3rd, 7th, and 14th. Assessment for a number of fibroblast and collagen synthesis on the wound of back tissue was conducted with the histological examination by painted using hematoxylin-eosin. The results concluded that Collagen application was influencing the mean of fibroblast higher than Amnion, and the lowest was controlled with statistically significant. The mean of collagen used Collagen lower than Amnion, and the lowest was control with statistically significant. It could be concluded that collagen application was preeminent in increasing the productivity of the fibroblast, as well as in developing forms of the collagen synthesis compared with Amnion and control.

Dentifrices used to aid plaque removal from dental surfaces and gums while teeth brushing. Propolis is one of bee products that can be added into dentifrices and its property is to inhibit plaque-forming bacteria growth. The main objective of this study was to rule out any plaque index differences before and after teeth brushing with and without propolis contained dentifrices. It was a quasi-experimental research with the single blind-parallel method. Subjects were 30 students from 33 Junior High School Bandung aged 11-13 years old, collected by purposive sampling technique. Subjects divided into groups which using propolis and without propolis dentifrices, teeth brushing. The plaque was assessed using the Patient Hygiene Performance (PHP) Index from Podsadley and Haley. Data collected would be tested using the paired t-test and independent t-test. This study concluded that there was a difference of plaque index before and after teeth brushing with and without propolis contained dentifrice. Indeed, the propolis contained dentifrice less much decrease the plaque index compared to the without propolis contained dentifrice.

Dentistry today has inherited technological advancement from other Dental Material sciences, examples are Nanocomposite and Giomers. Nanocomposites and Giomers are common materials used in Dentistry. But what are the implications when these materials are used in practice? The aim for this the study shows the analysis of tissue reaction due to implantation of Nanocomposite and Giomers. The subcutaneous tissue of a mouse is substituted with the human gum tissues. In the experimental group, Nanocomposite and Giomers were implanted in the subcutaneous tissue abdomen region in mice. The slides were made from the surrounding of implantation for both experimental and control groups. The evaluation of the effects of the implant is done in a time interval. Evaluated time intervals are 24 hours, 7" day, 14th day, 21st day and 28th day respectively. The amounts of inflammatory cells formation in both groups were compared.Once the results of the inflammatory cells are evaluated in the given time interval for Nanocomposite, Giomer, and control group then they are statistically analyzed. The statistics used in the experiments is Mann-Whitney and Wilcoxon. The conclusion of this research showed that statistically significant differences on lymphocytes value between treatment and control group.

The Thumb Rule of Leonardo da Vinci states that many proportions of the face show relationship with the length of thumb which is measured from the proximal tip of the proximal phalanx to the distal tip of the distal phalanx. Previous studies have shown that the length of the vertical dimension of occlusion (VDO) is similar to the length of thumb of the Caucasoid race. The purpose of this study is to determine whether the length of VDO have correlations with the length of thumb among those of the Mongoloid race. This study took a survey method with the analytical cross-sectional approach. A total of 80 students of Faculty of Dentistry who have fulfilled all population criteria were randomly chosen to measure the length of VDO and the length of the thumb. Results analyzed with Student's t-test statistic revealed that there was a significant difference between males and females in the length of VDO and the length of the thumb, however, there was no significant difference between the length of VDO and the length of the thumb. There were very strong correlations (P<0.05) between the length of VDO and the length of the thumb. As a conclusion, the length of thumb can be suggested as an objective method to determine the length of VDO in this population.

Dentist has long been recognized as a formal health profession. Health professionals have an important role to play in the fight against tobacco. Smoking tobacco is dangerous because it related disease and also due to it being labeled as a gateway to illicit drug abuse. As individuals, the dentist can help educate the population, as community members they can support anti-smoking policies and at a societal level, they can influence national and global tobacco control efforts. The associations between tobacco use and diseases affecting the oral cavity, such as periodontal disease and cancer, are now well recognized. This has lead to proposals from some members of the profession that members of the dental team should provide smoking cessation services. Before exploring effective ways to help smokers quit, it is important to understand the nature of the addictive process and how it affects both nicotine use and cessation attempts. The potential influence of dentists as agents of change is clear from even a brief consideration of the nature and conditions of the dentist-patient relationship. The dental practice setting provides a unique opportunity to assist tobacco users in achieving tobacco abstinence. The role of psychiatrists to support the effort, therefore, becomes all the more important.
