Comparison of Four Systems for Propagation of Coleus by Stem Cuttings
Authors: Peterson Bryan J. , Sanchez Olivia , Burnett Stephanie E. , Hayes Darren J.
Published: May 2018

Overhead mist (OM) facilitates the propagation of stem cuttings by preventing transpirational water loss. However, drawbacks to OM include the application of large volumes of water, potentially unsanitary conditions, irregular misting coverage, and leaching of foliar nutrients. We explored three alternatives to OM that might avoid these problems by applying moisture below, rather than overhead. These included 1) a submist (SM) aeroponic system configured to provide intermittent mist only to the rooting zone, 2) a subirrigation (SI) system that provided water via capillary action through perlite from a reservoir maintained below the base of each cutting, and 3) a subfog (SF) aeroponic system that was configured to provide constant fog only to the rooting zone. To initiate each system, we wetted perlite or filled reservoirs using either water or quarter-strength Hoagland solution. Stem cuttings of ‘Wizard Mix’ coleus (Plectranthus scutellarioides) were propagated in the systems for 21 days. Cuttings in the SM system produced more than three times as many roots as cuttings in the OM system, with roots more than six times the length. Root dry weights averaged 28 mg for cuttings in the SM system, compared with only 3.5 mg among cuttings receiving OM. The SF and SI systems produced results broadly comparable to the OM. Fertilizer did not consistently improve rooting measures across the systems. Although we observed few fine roots on cuttings rooted using SM, they transplanted well into a soilless substrate and quickly produced new root growth. The SM system used less than 1/5 the water used by the SI system, and less than 1/50 the water used by the SF system. In comparison, a single OM nozzle operating for 10 seconds released about one-third of the total water lost through transpiration from each SM system over the entire experiment. Our results show that SM systems merit further evaluation for propagation of plants by stem cuttings.

Published: May 2018

Specialty crop production in high tunnel systems has greatly expanded in the central United States. Strawberry (Fragaria ×ananassa) may be a viable high-value crop for high tunnel growers, but fall-planted production systems have a high opportunity cost in regard to winter production space. This study investigates the feasibility of spring-planted day-neutral strawberry cultivars in a high tunnel production system in Kansas. Furthermore, the goals of this report are to identify day-neutral cultivars that are successful in this production system and investigate the utility of evaporative cooling (EC), as they relate to fruit yield and marketability as well as incidence of gray mold (caused by Botrytis cinerea). High tunnel trials were conducted at the Kansas State University Olathe Horticulture Research and Extension Center during 2014 and 2015. Six commercially available cultivars were evaluated: Albion, Evie 2, Monterey, Portola, San Andreas, and Seascape in both years. Mature fruit (90% to 100% red) were harvested twice weekly for total and marketable (fruit with no defects) fruit yield. The results indicate that ‘Portola’ had the highest total fruit weight in both years at 0.60 and 0.51 kg/plant, respectively, and was significantly higher than ‘Monterey’, ‘Albion’, and ‘San Andreas’ in both years (P < 0.05). In 2014, ‘Portola’, ‘San Andreas’, and ‘Albion’ produced the largest total fruit average weight (grams/fruit) and were significantly larger than ‘Seascape’ and ‘Evie 2’ (P < 0.05). In 2015, ‘Portola’ had significantly larger fruit than all the other cultivars except San Andreas (P < 0.05). Marketability percent by weight ranged from 76.5% to 88.6% across both years and the highest marketability was observed with ‘Albion’ (89% and 83%) and ‘Monterey’ (85% and 84%) in 2014 and 2015, respectively. An examination of fruit production during the early, mid-, and late seasons was used to determine seasonal dynamics of each cultivar and the high tunnel system. The overall trend was that total fruit weight was highest during the midseason and total average fruit weight was largest in the early season. However, ‘San Andreas’ and ‘Seascape’ had similar levels of production between the early and midseason and had the lowest level of production in the midseason, particularly in the 2015 trial. In our trials, the use of EC did not affect fruit weight or gray mold incidence on strawberry fruit. Based on the crop productivity observed in our study, this production system has the potential to extend the season for strawberry growers in the central United States or provide a high-value rotational crop for existing high tunnel growers that does not require winter production space.
Training Systems for Cold Climate Interspecific Hybrid Grape Cultivars in Northern Climate Regions
Authors: Wimmer Madeline , Workmaster Beth Ann , Atucha Amaya
Published: May 2018

Training systems influence grapevine (Vitis sp.) size, shape, and canopy architecture, which ultimately affects yield and fruit composition. Cold climate interspecific hybrid grapes (CCIHG) have propelled the creation of a new and fast-growing grape and wine industry in the northeast and upper midwest of the United States. This study evaluated the effect of three training systems: high cordon (HC), midwire vertical shoot positioning (VSP), and modified Scott Henry (SH) on vine growth, yield, and fruit composition of four CCIHG cultivars, Brianna, Frontenac, La Crescent, and Marquette, during two growing seasons. The divided canopy training system SH increased the crop yield per meter of row in all cultivars relative to HC and VSP, despite reduction in crop size imposed by crop thinning in vines trained to SH. VSP-trained vines had lower yields compared with HC, and this was most evident during the second year of the study, as vines were still being trained when the study commenced. Despite the higher crop size associated with vines trained in a SH system, there were minimal differences in fruit soluble solid concentration (SSC), titratable acidity (TA), and pH at harvest time. No differences were observed in vine size, expressed as dormant cane pruning weights, among training systems possibly because of the control of vegetative vigor, especially in VSP-trained vines, through shoot positioning and summer pruning. CCIHG cultivars appear to have the capacity to support higher yields under SH and HC systems without compromising fruit quality; however, labor requirements involved in establishing and maintaining more complex training systems should be considered when selecting a training system for CCIHG cultivars.

Towards More Resilient Cities: Land Use and Urban Efficiency
Authors: Drewes J.E , Aswegen M. van , Richter M.
Published: May 2018

High rates of urbanization lead to a fragmented urban form with unequal access to jobs, amenities and public services. The lack of efficient and adaptive layout and design, integrated land uses (Paton et al., 2013; Saunders & Becker, 2015), urban connectivity (Taaffe et al., 1963) and sufficient forward planning at all levels of government is identified as a shortcoming which only exacerbates the consequences of urbanization. Based on an analysis of spatial planning principles, this paper proposes a practical and policy-related set of tools for improved forward planning, promoting resilient layout planning and smart land use management as a means to enable diverse settlements to respond to events such as intense levels of urbanization. The case study is focused on the dualistic urban settlements of South-Africa, but principles proposed could be applied to other settlements with similar spatially distorted patterns. The proposed set of tools could potentially improve urban resilience and efficiency.

Authors: Sedlak Otilija , Ćirić Zoran
Published: May 2018

The paper studies the sustainable development opportunities of the public passenger transport market in the globalized environment. The main aim of the research is to improve the competitiveness of sustainable public transport. Transportation needs to be considered as an important aspect of the development of cities in a sustainable manner and for an attempt to create a smart city. Those cities care about inhabitants, apply environmentally acceptable methods of waste management, offer more efficient public transportation, health care, and social system. Many studies have shown the relationship between effective public transportation services and sustainable development at the city level. European Commission is trying to motivate all the regional administration in an overall acceptance of sustainable urban mobility plans as part of the strategic vision for solving pressing problems in the process of functioning of modern cities. The purpose of this study is to present a concrete step in achieving the objectives of the "smart city" concept with the use of modern information technology in the traffic and passengers in the real-time monitoring process, tickets issuing, as well as passengers informing in Subotica, Serbia. There is a wide gap between community expectations from public transportation services and the actual quality of service provided. The resulted grounded theory has brought attention to the necessary reform of transportation institutions; transportation policy which is integrated into settlement development of the smart city strategy and consistency of economic systems; public transportation development proceeding from supply improvement; and finally, the need of awareness improvement via education. The research conclusion is a necessity of external fund allocation through emerging means of liberalization and public-private partnership and the introduction of the more demand responsive transportation system while taking into account sustainable consumption as well.
Validating the importance of criteria for assessing climate change scenarios
Authors: Srdjevic Bojan , Srdjevic Zorica , Lakicevic Milena
Published: May 2018

While evaluating climate impacts within different climate change scenarios, analysts and stakeholders may have different goals and therefore it is usually difficult to define a common decision-making framework applicable for various practical uses. In this paper, we combine two different group decision-making methodologies to prioritise criteria for assessing output information from regional climate models. The first is based on use of a multi-criteria analytic hierarchy process (AHP) to determine weights of criteria as cardinal information about their importance. The second methodology uses two voting methods, namely Borda count and Approval voting, to generate ordinal information (ranks) for criteria. A set of five criteria is assessed by 16 PhD students from the field of climatology, and generated decisions about their importance in the validation of regional climate models' quality are summarised, compared, and critically discussed. The paper is closed with recommendations for further research.

Authors: Salari M. , Rakhshandehroo G. R. , Nikoo M. R.
Published: May 2018

Optimization methods are used to study and survey the optimal values for input factors and effect of optimized parameters on response variables. In this study, the effect of different factors on ciprofloxacin (CIP) removal of water soluble was studied. In this regard, a multi-objective optimization was performed utilizing the Taguchi method based on a grey relational analysis. Optimum levels of factors were determined to optimize three responses simultaneously with grey Taguchi. Meanwhile, grey relational analysis was applied to model and optimize three target responses, namely, CIP removal, chemical oxygen demand (COD) removal, and sludge to iron ratio. Multi-objective optimization results obtained based on grey relational analysis showed that the optimal value of the input factors were CIP concentration of 100 mg/L, H2O2 concentration of 100 mM, Fe(II) concentration of 10 mM, pH of 3, and a reaction time of 15 min. To confirm the results, the values obtained through a confirmation test were examined. Multi-objective optimization results from process factors were determined by analysis of variance (ANOVA) analysis and grey Taguchi method. Based on ANOVA analysis for the grey relational grade, Fe(II) concentration and H2O2 concentration were found to be the most influencing factors.

Published: May 2018

Combinations of antiretroviral drugs are successfully used to treat HIV-infected
patients. However, drug resistance is a major problem that makes discovery of new antiretroviral
drugs an ongoing priority. The ribonuclease H (RNase H) activity of the HIV-1 reverse
transcriptase catalyzes the selective hydrolysis of the RNA strand of RNA:DNA heteroduplex
replication intermediates, and represents an attractive unexploited target for drug
development. This review reports on recent progress in the characterization of HIV-1
RNase H inhibitors from 2013 to 2016, describing their chemical structures, structureactivity
relationship and binding modes. Focus is given to emerging medicinal chemistry
principles and insights into the discovery and development of RNase H inhibitors.

Published: May 2018

Background:

Tuberculosis (TB) is the second important cause of death worldwide caused by a bacterium calledMycobacterium tuberculosis. There is a need to find and develop new Anti-TB medications that are effective, inexpensive and suitable with human immunodeficiency virus and other anti-TB drugs used in many countries and mainly the developing countries where the disease is widespread. These drugs must be designed to shorten treatment time and to be active against resistant forms of the mycobacteria that will help to increase the patients compliance. A key compound which could be used as a lead to meet these requirements, is the thiolactomycin (TLM). This antibiotic which is naturally available has an ability to treatM. tuberculosisby inhibiting condensing enzymes called FAS II (mtFabH, KasA and KasB) which are related to biosynthesis of mycolic acid.

Methods:

Our main aims are to design and synthesize analogues of TLM as new lead molecules which could be a possible anti–TB candidate. To overcome the synthetic challenges associated with preparing the chiral TLM analogues; we synthesized and investigated a series of triazole analogues as inhibitors of KasA enzyme and the whole cellMycobacteria. A series of twelve compounds were synthesized, purified and fully characterized using several spectroscopic techniques. Molecular modelling studies for our synthesised compounds were achieved by using a modelling program called AutoDock 4.2 utilising rigid docking.

Results:

Our results indicate that analogues of TLM show a good activity as compared to TLM.

Conclusion:

The activity obtained for the synthesized compounds againstMycobacteria tuberculosisindicate that the synthesised compounds1,2,6and9are pharmacologically active as they restrained the growth of theMycobacteriabacteria.

Published: May 2018

Introduction:

Obesity, a disease characterized by an excess of adipose tissue, is a worldwide issue of growing interest in public health.

Methods:

The multifactorial etiology and pathogenesis of obesity strongly orient the scientific community in considering it as a chronic disease without an effective therapy that works for all patients affected by this clinical condition. This leads to a proliferation of non-scientific and dangerous treatment proposals and fake news. The Dietetic and Clinical Nutrition Unit at Bolzano Hospital in Italy has adopted a new strategy based on transparency to optimize time for the first visit and particularly to increase patients’ knowledge and motivation.

Results:

This new strategy provides a preliminary consultation between patients who ask for a nutritional examination and a clinical team composed of a clinician, a dietician and a psychologist. We discuss the preliminary results obtained during the period between February 2010 and March 2016.

Published: May 2018

Background:

Due to importance and unique properties of Multi-Wall Carbon Nanotube(s) (MWCNT), in the present study, effectiveness of these materials in Water Base Mud (WBM) is evaluated.

Objective:

The impacts of mud additives, local water and the addition of phases of bentonite and surfactants on the rheological properties, water loss and stability of water base mud in the absence of Multi-Wall Carbon Nanotube have been experimentally investigated.

Materials and Methods:

Then, the same experiment performed in the presence of Multi-Wall Carbon Nanotube to determine the efficiency and impact of Nanoparticles (NPs) on the properties of water base mud. The results have shown that additives, local water, Multi-Wall Carbon Nanotube dimensions, addition phase of bentonite and surfactants have influenced the rheological properties of the water base mud.

Results:

When Multi-Wall Carbon Nanotubes and polyethylene glycol alone or together are added, the performance terms of rheological properties decrease as by the subsequent order CNT; CNT + PEG; PEG. Multi-Wall Carbon Nanotube improves shale integrity and increases shale recovery.

Conclusion:

In general, the presence of Multi-Wall Carbon Nanotube increases the efficiency of polymers and rheological properties of the water base mud and eventually the shale stability is achieved.
Adolescent BMI: The Importance of Intrinsic and Extrinsic Factors
Authors: Jacobs Molly
Published: May 2018

Objectives:

Research shows that weight trends in adolescence persist into adulthood, but do the same factors contribute to weight in adolescence as in adulthood? Are extrinsic factors presumably more important than intrinsic characteristics? This study identifies the correlation between BMI and various intrinsic and extrinsic factors and evaluates their relative importance in BMI development. It compares the primary determinants for adolescents (12-20 years old) and adults (21+ years old).

Methods:

Using 15 years of panel data, generalized linear models, we assessed the impact of extrinsic-environmental, biological, geographic and household-and intrinsic-sexual activity, substance use, desire to lose weight,etc.-characteristics on adolescent and adult BMI. Multinomial logit models tested the contribution of these characteristics to weight categories.

Results:

Race and age were the most significant BMI correlates at all ages. This remains true for weight classification as well. For young adolescents, intrinsic factors are highly deterministic, while extrinsic factors play no role. As adolescents age into adults, intrinsic factors continue to be deterministic, while extrinsic covariates also emerge as deterministic. Intrinsic determinates of significance include age of first sexual encounter, tobacco experimentation, perspective on general health, and desire to lose weight (or stay the same weight).

Conclusion:

While biological/genetic attributes are the largest determinants of BMI at every age, intrinsic factors play a larger role in adolescent BMI development than adults. As individuals age, intrinsic determinants remain important, but extrinsic characteristics contribute significantly to weight classification. Thus, the weight determinants differ between adolescents and adults suggesting different methods of policy intervention be used for adolescents and adults.

BACKGROUND

Community-based participatory research is an effective tool for improving health outcomes in minority communities. Few community-based participatory research studies have evaluated methods of optimizing smartphone apps for health technology-enabled interventions in African Americans.

OBJECTIVE

This study aimed to utilize focus groups (FGs) for gathering qualitative data to inform the development of an app that promotes physical activity (PA) among African American women in Washington, DC.

METHODS

We recruited a convenience sample of African American women (N=16, age range 51-74 years) from regions of Washington, DC metropolitan area with the highest burden of cardiovascular disease. Participants used an app created by the research team, which provided motivational messages through app push notifications and educational content to promote PA. Subsequently, participants engaged in semistructured FG interviews led by moderators who asked open-ended questions about participants’ experiences of using the app. FGs were audiorecorded and transcribed verbatim, with subsequent behavioral theory-driven thematic analysis. Key themes based on the Health Belief Model and emerging themes were identified from the transcripts. Three independent reviewers iteratively coded the transcripts until consensus was reached. Then, the final codebook was approved by a qualitative research expert.

RESULTS

In this study, 10 main themes emerged. Participants emphasized the need to improve the app by optimizing automation, increasing relatability (eg, photos that reflect target demographic), increasing educational material (eg, health information), and connecting with community resources (eg, cooking classes and exercise groups).

CONCLUSIONS

Involving target users in the development of a culturally sensitive PA app is an essential step for creating an app that has a higher likelihood of acceptance and use in a technology-enabled intervention. This may decrease health disparities in cardiovascular diseases by more effectively increasing PA in a minority population.
Effectiveness of a Multimodal Digital Psychotherapy Platform for Adult Depression: A Naturalistic Feasibility Study (Preprint)
Authors: Marcelle Enitan T , Nolting Laura , Hinshaw Stephen P , Aguilera Adrian
Published: May 2018

BACKGROUND

Although psychotherapy is one of the most efficacious and effective treatments for depression, limited accessibility to trained providers markedly limits access to care. In an attempt to overcome this obstacle, several platforms seeking to provide these services using digital modalities (eg, video, text, and chat) have been developed. However, the use of these modalities individually poses barriers to intervention access and acceptability. Multimodal platforms, comprising those that allow users to select from a number of available modalities, may be able to provide a solution to these concerns.

OBJECTIVE

We aimed to investigate the preliminary effectiveness of providing psychotherapy through a multimodal digital psychotherapy platform. In addition, we aimed to examine differential responses to intervention by gender, self-reported physical health status, and self-reported financial status, as well as how prior exposure to traditional face-to-face psychotherapy affected the effectiveness of a multimodal digital psychotherapy intervention. Finally, we aimed to examine the dose-response effect.

METHODS

Data were collected from a total of 318 active users of BetterHelp, a multimodal digital psychotherapy platform. Data on physical health status, financial status, and prior exposure to psychotherapy were obtained using self-report measures. Effectiveness was determined by the extent of symptom severity change, which was measured using the Patient Health Questionnaire at Time 1 (time of enrollment) and Time 2 (3 months after enrollment). Intervention dosage was measured as the sum of individual therapist-user interactions across modalities.

RESULTS

Depression symptom severity was significantly reduced after the use of the multimodal digital psychotherapy intervention (P<.001). Individuals without prior traditional psychotherapy experience revealed increased improvement after intervention (P=.006). We found no significant dose-response effect of therapy, nor significant differences in outcomes across gender, self-reported financial status, and self-reported physical health status.

CONCLUSIONS

Users of BetterHelp experienced significantly reduced depression symptom severity after engaging with the platform. Study findings suggest that this intervention is equally effective across gender, self-reported financial status, and self-reported physical health status and particularly effective for individuals without a history of psychotherapy. Overall, study results suggest that multimodal digital psychotherapy is a potentially effective treatment for adult depression; nevertheless, experimental trials are needed. We discuss directions for future research.
Dokter Lubis Program
Authors: Marlina Siti
Published: May 2018

.....The Indonesian government via a program called Healthy Living Community Movement (GERMAS) emphasizes the principle of healthy life style for community, family and individual to create healthy nation estimated number of children with special needs in Indonesia in 2015 is about 7-10% of the total number of children. In this regards, children with special needs should be assisted to achieve their better condition of health through healthy lifestyle. Handling of children with special needs aims at emphasizing the potential of the children rather than focusing on their barriers, and also maintaining an optimistic attitude to be able to provide medical, psychological, and prevention services. The various conditions of children with special needs are not an excuse to avoid them, but rather generate awareness on respect to the diversity of individuals and give attention and services as ideal as they need. One effort developed to handle children with special needs is the ‘Dokter Lubis’ program (school children as peer educator for children with special needs) which includes promotive, preventive, curative and rehabilitative activities......
Developmental Trial of Maternity Education Control Cards

Background: The behavior of a pregnant woman in maintaining her health during pregnancy is influenced by her knowledge of pregnancy. The greater the knowledge of pregnant women about pregnancy, the better the attitude of pregnant women in maintaining their pregnancy. Consequently, a primary care physician who is a health manager of pregnant women needs to pay attention to this knowledge aspect. Primary care physicians should be able to quickly identify the level of knowledge of pregnant women about pregnancy and determine whether that knowledge is sufficient. For that purpose, primary care physicians need to have the right measurement instruments.Objectives: This study aimed to develop, validate and test the instruments that primary care physicians can use to identify and add to pregnant women’s level of knowledge about pregnancy.Methods: This study involved research and development of a validated instrument that consisted of several stages, namely development, validation and testing. Validation was done through two stages, specifically content validation by experts and face validation by 7 doctors. The experimental phase was a quasi-experimental research with 35 pregnant women who presented for antenatal examination at the Puskesmas Banguntapan I (Community and Primary Health Care Center). T-tests were used to determine whether there was a significant difference between the knowledge of pregnant women before and after using the Maternity Education Control Cards.Results: The validated instrument called the Maternity Education Control Card developed by primary care physicians can be used to identify and increase the level of knowledge of pregnant women about pregnancy. The Maternity Education Control Card was validated by several experts, including communication experts, obstetricians and the Maternal and Child Health Program Coordinator at Bantul Regency. Layout, style, accessibility, and feasibility were assessed by a team of validators at the Puskesmas Banguntapan I (7 doctors and 1 midwife coordinator). The data analysis showed that there was a significant difference between pre-test and post-test scores (p = 0.000). This value was not influenced by age variables, educational level, number of pregnancies nor previous antenatal care frequency, but the level of education did affect the post-test value. The duration required for education was between 9 - 20 minutes, with an average of 14.63 minutes (± 2.61). The duration required for education related to the delta of pre and post-test values. The greater the delta, the longer time required for education.Conclusions: Maternity Education Control Card has been successfully established, validated and proven to significantly increase pregnant women’s knowledge about pregnancy.
Case Report: Worm Infection in Children

Published: May 2018

........The problem in this case was not about medical treatment of a pinworm disease, which was probably easily treated with antihelmintic within 1-2 days. At a glance this problem seems trivial, however, the interesting and challenging aspects of the above case are: 1) How to maintain the sustainability of clean and healthy life behavior by patients and their families, so the risk of worm infection does not occur in the future; 2) Behavior and use of latrines in the family where only 1 exists for all family members, to be healthy and regularly managed; and 3) How to educate the mother of the patient that this worm infection can occur in an outbreak, if the healthy lifestyle is not properly done while she keeps selling candle ice for elementary school children near their home........

In 2016, Hazara Division reported his major outbreak of Dengue fever. In this context, current epidemiological and serological survey conducted to highlight the actual burden of Dengue fever in cities of Hazara Division. Blood samples were taken from the total of 1462 suspected people for detection of Dengue antibodies. Among these patients, 1359 (93%) were found to be positive for Dengue, including 965 (71%) males and 394 (29%) females. Distribution in keeping the presence of antibodies shows 897 (66%) IgM positive people. Second most frequently seen antibodies were both IgG and IgM in 435 (32%) people. Presence of IgG antibodies was detected in 27 (2%) individuals. 1142 (84%) of Dengue positive people were not found to be symptomatic while rest of 217 (16%) observed with various symptoms. In this outbreak peak incidence of Dengue fever was observed in Manshera city. Although minimum was seen in Abbottabad city. To conclude, this might be the largest outbreak in the history of Hazara Division and second in Khyber Pakhtunkhwa. We recommend that policymakers and the government of Khyber Pakhtunkhwa desperately need to make efforts to prevent this mounting ratio of Dengue fever and implement the vector management policies by environmental measures and promote awareness in this area.
TEATRO EN TRANSICIÓN. DRAMATURGIA, POLÍTICA Y RELACIONES SOCIALES EN SANTA FE (ARGENTINA), ENTRE LA ÚLTIMA DICTADURA Y LA TRANSICIÓN DEMOCRÁTICA
Authors: Alonso Luciano
Published: May 2018

No estudo dos fenômenos artísticos e literários durante a última ditadura cívico-militar argentina (1976 -1983), tem passado pelo predomínio de uma interpretação baseada na noção de “apagão cultural” provocado pela repressão e censura, prevalendo, a consideração de uma certa “resistência cultural”. Por outro lado, a historiografia sobre as atitudes sociais frente às ditaduras tem mostrado a existência de amplas “zonas cinzentas” e a inextricável combinação de consentimentos e dissidências. Este texto enfoca o desenvolvimento do “teatro independente” santafesino, a partir do momento central da ditadura até a transição democrática. Apresentando uma caracterização geral do espaço teatral e a postulação de uma “comunidade” formada em torno de certas relações sociais, o texto enfoca alguns episódios que permitem uma análise mais densa. Demonstra a coexistência de atitudes de integração no quadro institucional ditatorial com outras de resistência micropolítica e de expressão de uma subjetividade dissidente. Finalmente, postula que a transformação dessas relações em termos de transição política, era da mão de uma transição geracional e estética na construção de uma nova dramaturgia.

Cedera saraf perifer menyebabkan jumlah neuron menurun di ganglion sensorik, sehingga regenerasinya tidak baik. Pemberian Citicoline telah dilaporkan dapat memperbaiki kondisi fungsi motorik dan mencegah nyeri neuropati pada model tikus cedera saraf perifer. Pada ganglion sensorik, peningkatan regenerasi terkait dengan SIRT1 yang mendorong kelangsungan hidup neuron. Penelitian ini bertujuam untuk menguji hipotesis bahwa pemberian citicoline meningkatkan ekspresi gen SIRT1 fase akut pada model tikus cedera saraf mentalis. Setelah dianestesi, saraf mentalis kanan dijepit dengan klem tanpa gerigi selama 30 detik. Tikus-tikus dibagi menjadi 3 kelompok, kelompok operasi sham, kelompok cedera dan kelompok citicoline. Citicoline diberikan secara i.p. 50 mg/kg BB/hari selama 7 hari. Tikus dinekropsi pada hari ke-1, 3 dan 7 setelah cedera. Pada hari ke-1,3,7 (3 tikus per kelompok), ganglion trigeminal kanan dipotong dan diekstraksi RNA, reverse transcriptase PCR dan qPCR untuk melihat ekspresi gen SIRT1. Hasil penelitian menunjukkan peningkatan ekspresi SIRT1 hari ke-7 setelah cedera saraf mentalis tikus yang diberikan terapi citicoline i.p. Sebagai kesimpulan, pemberian citicolin segera setelah cedera saraf mentalis meningkatkan ekspresi SIRT1 pada hari ke-7.
