Indonesia’s Democracy in the 21st Century: A Book Review
Authors: Rahma Bachtiar Farahdiba
Published: March 2019

There are plenty of books wrote about Indonesia’s democracy by foreign scholars. Yet, many of them are very heavy read when it comes to politics. The book is an alternative. Intentionally wrote to offer brief overview about Indonesia’s, the book by McDonald indeed is presented to be ease for understanding yet contains fruitful topics on Indonesia’s democracy. His long experience as a journalist and writer of the classic book -Suharto’s Indonesia, as well as his journey to the country gave him adequate capacity to understand Indonesia better in the past and today. And thus it is why as mentioned before that he offers what he called “authoritative introduction”, because he is not a pure academia. Therefore, it is better not to expect depth analysis about any particular subject. But the novelty of the book lies on its details of some particular cases which not too often revealed by other books.

Published: March 2019

The aim of this study was to investigate the retention forces of secondary telescopic crowns made of polyetherketoneketone (PEKK) in combination with primary crowns made of four different dental alloys and to determine whether the retention forces change in the course of up to 5000 simulated wear cycles. A total of four groups of telescopic crowns were investigated: group 1: 10 primary crowns made of a gold alloy (NEOCAST®3), group 2: 10 primary crowns made of a non-precious metal alloy (Girobond NB), group 3: 10 primary crowns made of zirconium (Cercon®base) and group 4: 10 primary crowns made from PEKK (Pekkton®ivory). The corresponding secondary crowns were made from PEKK in all the four groups. Each pair was fixed axially in a wear simulator specifically designed for the study. Overall, 10,000 joining and separating cycles were performed for each group. To simulate intraoral conditions, a saliva substitute served as a lubricant. Force transducers were used to record the retention forces and after completing 10,000 cycles, the surface of each primary crown was examined using a scanning electron microscope (SEM). All groups showed an increase in the retention force for the first 2000 cycles which stayed constant for the remaining 8000 cycles. The Pekkton®ivory/Pekkton®ivory and NEOCAST®3/Pekkton®ivory combinations displayed mean retention force values of 16 N after a slight increase in the retention force. The Cercon®base/Pekkton®ivory and Girobond NB/Pekkton®ivory combinations displayed an initially high increase in the retention force and then showed a mean retention force of up to 29 N. All primary crowns displayed surface wear. Zirconium primary crowns showed the least wear compared to PEKK and the gold and non-precious metal alloys.
Phylogenetic relationships of Pakistan Gelidium (Gelidiales, Rhodophyta) species with recognition of Gelidium pakistanicum stat. nov.
Authors: Freshwater D. Wilson , Shahnaz Laila
Published: March 2019

Two species of Gelidium, Gelidium usmanghanii and Gelidium pusillum var. pakistanicum are reported only from Pakistan, but their taxonomic status, phylogenetic relationships, and distributions have not been assessed with molecular data. Analysis of rbcL sequences revealed that G. usmanghanii was a distinct species with a distribution extending at least to the coast of Oman. This analysis also resolved G. pusillum var. pakistanicum within a Gelidium millariana species complex that was distantly related to G. pusillum. Further analyses of rbcL and COI-5P sequences showed that G. pusillum var. pakistanicum was a distinct species in this complex, and based on these molecular, and previous morphological results, this variety is elevated to the rank of species as Gelidium pakistanicum stat. nov.
Measuring the chronology of the translational process of molecular genetic discoveries
Authors: Rousseau François , Lindsay Carmen , Labelle Yves , Giguère Yves
Published: March 2019

Background

The process of technology validation and transfer of new molecular diagnostic tests towards the clinic faces challenges and needs to be improved. There is no empirical measure of the chronology and pace of technology transfer of molecular genetic discoveries.

Methods

We studied these for 29 molecular genetic test discoveries in order to (1) provide estimates of the timeframe between discovery of a clinical application and complete clinical implementation, and (2) compare the trajectories between different new tests to identify common patterns. We identified 11 publicly available “timestamps” for the technology transfer process ranging from discovery of the marker to use in a clinical setting. For each test selected, we searched public databases to identify available timestamps and dates. We plotted and compared trajectories of individual tests, including chronology.

Results

We show that there is much variability in the chronology of transfer between biomarkers. The median time between discovery of the marker and availability of the clinical test was 9.5 years (minimum 1). There was a median time of 18 years between test discovery and FDA approval (minimum 7 years), and it took a median of 17 years between discovery and the availability of a certified reference material for the 10 assays that have one (minimum 9 years).

Conclusions

We conclude that new molecular genetic tests take significant time between discovery and clinical implementation, and that further work is needed to pinpoint key factors, including policy and organization factors, that may allow for improving and streamlining this process.
Clinical impact of citrate-containing tubes on the detection of glucose abnormalities by the oral glucose tolerance test
Authors: Bonetti Graziella , Giavarina Davide , Carta Mariarosa
Published: March 2019

Background

Plasma glucose levels provide the cornerstone of diabetes evaluation, and so it is crucial that clinical laboratories provide accurate and reliable plasma glucose results. To prevent in vitro glycolysis, citrate is used. Here, we present the first study on the 75-g oral glucose tolerance test (OGTT) using the currently available new citrate-containing tubes in liquid and granular forms and the previous sodium fluoride (NaF) for the diagnosis of carbohydrate metabolism disorders and gestational diabetes mellitus (GDM) according to the American Diabetes Association (ADA) guidelines.

Methods

The 75-g OGTT was performed in 147 volunteers, 83 of whom were pregnant women. Blood was collected in NaF/K3 ethylenediaminetetraacetic acid (EDTA) and NaF/Na2EDTA/citrate in liquid form in tubes in Brescia and in NaF/K2Ox and NaF/Na2EDTA/citrate in granular form in Vicenza. Glucose was measured within 3–4 h from the OGTT. The mean biases were calculated and compared with the desirable bias (<± 2.1%).

Results

OGTT glucose concentrations were higher in citrate tubes when compared to NaF-containing tubes. When citrate tubes were used, GDM increased to 12.5 and 11.7% in Brescia and Vicenza, respectively. Impaired fasting glucose (IFG), impaired glucose tolerance (IGT) and diabetes mellitus (DM) increased to 36.7, 6.7 and 3.4%, respectively, in Brescia. In Vicenza, an increase of 47 and 1.9% in IFG and IGT, respectively, was found.

Conclusions

OGTT glucose measurement in citrate-containing tubes was shown to be more effective than those containing only NaF in diagnosing carbohydrate disorders. This new glycolysis inhibitor seems to be a necessary preanalytical tool for accurate and reliable plasma glucose results.
Selective recovery of polyphenols from MDF process waters by adsorption on a macroporous, cross-linked pyrrolidone-based resin
Authors: Lindemann Martin , Rieder-Gradinger Cornelia , Kuncinger Thomas , Srebotnik Ewald
Published: March 2019

A scalable, fixed-bed adsorption system for the removal and selective recovery of polyphenols (lignans and stilbenes) from medium-density fiberboard (MDF) process waters was developed. Before adsorption, fibers and non-colloidal substances were removed from process water by centrifugation, while colloidal fatty and resin acids were removed by filtration through a 30-kDa cut-off membrane. Polyphenols were then isothermally adsorbed on a medium-pressure liquid chromatography (MPLC) column packed with Divergan® RS, a regenerable macroporous, cross-linked pyrrolidone-based [polyvinylpolypyrrolidone (PVPP)] resin. Loading at acidic pH and subsequent gradient elution of polyphenols with methanol were monitored at 280 nm, and elution conditions for selective polyphenol recovery were optimized based on gas chromatography/mass spectrometry (GC/MS) analyses of the obtained fractions. Lignans were eluted in successive fractions containing the individual lignans in different proportions, followed by pinosylvin in a separate fraction. The capacity of the PVPP for hydroxymatairesinol (HMR) as a model lignan was determined to be 37.4 mg g−1 at 1% breakthrough. Highly polar substances such as sugars and sugar alcohols, however, were not retained on the column and remained in the flow-through. The results revealed the benefits of PVPP for the recovery of potentially valuable polyphenols from MDF process waters while reducing carbon load and toxicity for subsequent biological treatment.
The influences of stimulation mode and stimulus frequency on acoustic reflex latency (ARL) among young adults

Published: March 2019

Introduction

Acoustic reflex (AR) is a valuable clinical test for hearing diagnosis. Parameters of AR such as its amplitude and threshold have been commonly reported in research. Acoustic reflex latency (ARL) has not been widely studied and more research is warranted to determine its basic properties and clinical usefulness. The present study aimed to determine the influences of stimulation mode and stimulus frequency on ARL.

Methods

In this study, 52 healthy young adults were enrolled (mean age = 23.2 ± 0.8 years, 61.8% were males). They underwent the standard AR testing and ARL values were computed. Both ipsilateral and contralateral recordings were made at 500, 1000, 2000 and 4000 Hz frequencies.

Results

The ARL values obtained are consistent with the findings from the previous studies. Two-way analysis of variance (ANOVA) revealed that the ARL values were not statistically influenced by either stimulation mode (p = 0.061) or stimulus frequency (p = 0.598).

Conclusion

Among young adults, ARL does not appear to be influenced by stimulation mode and stimulus frequency. Further large scale research is warranted to support the present study’s findings. The preliminary normative data for ARL obtained in this study can serve as the reference for future research involving this particular population.

Authors: Movlavi Sedigheh , Salehi Shayesteh
Published: March 2019

Introduction

The nursing process is a method for solving the problems used to meet the health and care needs of individuals. Using the nursing process enables nurses to use critical thinking for clinical judgment and their care activities. Thus, the present study was conducted to specify the effect of the implementation of the nursing process on students’ health behaviors.

Materials and methods

The population was first-year high school girl students in Kurdistan in 2016–2017 that comprised 90 students. The questionnaire used was one for the health needs of adolescent girls and was a standard questionnaire with 65 questions. The purpose was to evaluate the health needs of girls from different aspects (mental health, emotional needs, social health needs, educational needs, physical health needs, belief needs). Students were randomly assigned into experimental and control groups and nursing-based interventions were done for the experimental group. Data were analyzed in SPSS.

Results

The results showed no significant differences between students’ health behaviors before the implementation of the nursing process, but after performing the intervention according to the implementation of the nursing process, the status of observing the students’ health behaviors significantly improved.

Conclusion

Given the positive effect of the nursing process on enhancing students’ health behaviors, this type of nursing intervention should be done in other studies and in clinics to enhance the health of the students.

Authors: Abiodun Olumide , Ladele Akindele , Olu-Abiodun Oluwatosin , Ashipa Temitope
Published: March 2019

Purpose

The burden of hypertension is rising both globally and in Africa specifically. We determined the prevalence of hypertension and the risk factors for clinical hypertension in a population of new university intakes over a 4-year period.

Methods

We analyzed retrospectively, the records of 6980 older adolescents (15–19 years). We used population-specific metrics to categorize blood pressure (BP) based on the 2017 Clinical Practice Guidelines by the American Academy of Pediatrics.

Results

The overall prevalence of high BP in our study was 25.1% [95% confidence interval (CI) 24.1–26.2] for elevated BP, 19.8% (95% CI 18.9–20.8) for stage 1 hypertension, and 5.5% (95% CI 5.0–6.1) for stage 2 hypertension. The prevalence of stage 2 hypertension was 8.7% (7.5–9.5) among the male participants and 3.2% (95% CI 2.7–3.2) among the female participants (p < 0.001). The multivariate analyses demonstrated an increased risk of high levels of BP (p < 0.001) with age (1.21: 95% CI 1.16–1.26), waist-to-height ratio (WHtR) (1.05: 95% CI 1.04–1.05), z-score for body mass index (BMI) (1.47: 95% CI 1.41–1.54), and hemoglobin concentration (1.10: 95% CI 1.09–1.12). It demonstrated a reduced risk of high levels of BP (p < 0.001) being female (0.35: 95% CI 0.32–0.39).

Conclusions

Hypertension, its risk factors and the risk of cardiovascular diseases in later life are prevalent in our Nigerian adolescent population. There is, therefore, a need for the development, evaluation and implementation of context-appropriate strategies and interventions to mitigate the risk of hypertension among adolescents, and cardiovascular diseases later in life.
Stability Analysis of a Mathematical Model for Glioma-Immune Interaction under Optimal Therapy
Authors: Khajanchi Subhas
Published: March 2019

We investigate a mathematical model using a system of coupled ordinary differential equations, which describes the interplay of malignant glioma cells, macrophages, glioma specific CD8+T cells and the immunotherapeutic drug Adoptive Cellular Immunotherapy (ACI). To better understand under what circumstances the glioma cells can be eliminated, we employ the theory of optimal control. We investigate the dynamics of the system by observing biologically feasible equilibrium points and their stability analysis before administration of the external therapy ACI. We solve an optimal control problem with an objective functional which minimizes the glioma cell burden as well as the side effects of the treatment. We characterize our optimal control in terms of the solutions to the optimality system, in which the state system coupled with the adjoint system. Our model simulation demonstrates that the strength of treatment

, 4 h reaction time, pH 4.5, dose of histidine 1 %. Under the optimum reaction conditions, the tensile and burst indexes of the sheet made from laccase/histidine treatment were increased by 25.2 % and 34.0 %, compared with that of the control sample. The SEM results showed that compared with the control sample, the fibrillation of the fiber modified with laccase/histidine was more obvious. Finally, the content of acid-insoluble lignin of the fiber was determined. The content of acid-insoluble lignin of the control sample was 29.2 %, and the content of acid-insoluble lignin of the fiber treated by laccase/histidine system in optimum reaction conditions was 16.0 %, which decreased by 13.2 %. Laccase/histidine system could improve the physical properties of recycled fiber, alleviate fiber decay, which are of great significance to solve the resource shortage and environment pollution of the paper-making industry.
Separation of trivalent actinides and lanthanides using various ‘N’, ‘S’ and mixed ‘N,O’ donor ligands: a review
Authors: Bhattacharyya Arunasis , Mohapatra Prasanta K.
Published: March 2019

Separation of trivalent actinide (An) and lanthanide (Ln) elements is one of the burning topics in the back end of the nuclear fuel cycle due to the similarity in their chemical behaviour. A significant amount of research is being carried out worldwide to develop suitable ligands for the separation of the trivalent actinides and lanthanides. Some of the research groups are engaged in continuous improvement of the di-ethylene-triamine-penta acetic acid (DTPA) based Ln/An separation method, whereas extensive research is going on for the development of the lipophilic and hydrophilic ‘N’ donor heteropolycyclic ligands as the actinide selective ligand. A number of ‘S’ donor ligands are also explored for the Ln/An separation. In the present review, we made an attempt to highlight various separation processes based on soft donor ligands developed for Ln/An separations. Beside the conventional solvent extraction processes, separation possibilities membrane based and solid phase extraction techniques are evaluated for the Ln/An separation and are compiled in the present review.

Authors: Fernández Paradas Antonio Rafael , Sánchez Guzmán Rubén
Published: March 2019

Aunque fue uno de los grandes taquillazos cinematográficos de la época, Juana la Loca… de vez en cuando (José Ramón Larraz, 1983), recibió unas duras críticas por parte del público especializado, que veían en la cinta una penosa manera de hacer cine. Personajes, ambientación, guion, interpretaciones, etc., nada escapó a la pluma de los críticos, que se cebaron duramente con ella. Aun así, el público conectó a la perfección con ella, no en vano, la Corte de los Reyes Católicos vino a hacer suya la lejana Transición española. Mediante la siguiente investigación, queremos poner en valor esta importante aportación del cine español, como un documento que refleja a la perfección la vida política, social, cultural y artística de la Transición española, ofreciendo un compendio que permita comprender la minuciosidad e intelectualidad del guion en toda su complejidad.

Representation of Haltere Oscillations and Integration with Visual Inputs in the Fly Central Complex
Authors: Kathman Nicholas D. , Fox Jessica L.
Published: March 2019

The reduced hindwings of flies, known as halteres, are specialized mechanosensory organs that detect body rotations during flight. Primary afferents of the haltere encode its oscillation frequency linearly over a wide bandwidth and with precise phase-dependent spiking. However, it is not currently known whether information from haltere primary afferent neurons is sent to higher brain centers where sensory information about body position could be used in decision making, or whether precise spike timing is useful beyond the peripheral circuits that drive wing movements. We show that in cells in the central brain, the timing and rates of neural spiking can be modulated by sensory input from experimental haltere movements (driven by a servomotor). Using multichannel extracellular recording in restrained flesh flies (Sarcophaga bullataof both sexes), we examined responses of central complex cells to a range of haltere oscillation frequencies alone, and in combination with visual motion speeds and directions. Haltere-responsive units fell into multiple response classes, including those responding to any haltere motion and others with firing rates linearly related to the haltere frequency. Cells with multisensory responses showed higher firing rates than the sum of the unisensory responses at higher haltere frequencies. They also maintained visual properties, such as directional selectivity, while increasing response gain nonlinearly with haltere frequency. Although haltere inputs have been described extensively in the context of rapid locomotion control, we find haltere sensory information in a brain region known to be involved in slower, higher-order behaviors, such as navigation.

SIGNIFICANCE STATEMENTMany animals use vision for navigation; however, these cues must be interpreted in the context of the body's position. In mammalian brains, hippocampal cells combine visual and vestibular information to encode head direction. A region of the arthropod brain, known as the central complex (CX), similarly encodes heading information, but it is unknown whether proprioceptive information is integrated here as well. We show that CX neurons respond to input from halteres, specialized proprioceptors in flies that detect body rotations. These neurons also respond to visual input, providing one of the few examples of multiple sensory modalities represented in individual CX cells. Haltere stimulation modifies neural responses to visual signals, providing a mechanism for integrating vision with proprioception.

Saray helvası Türkiye’ye özgü
geleneksel unlu bir şekerlemedir. Gevrek, lifli ve düşük su aktiviteli bir ürün
olmasından dolayı depolama sırasında öncelikle fiziksel bozulmalar
görülmektedir. Bu çalışmada, depo bağıl neminin ve sıcaklığının saray
helvasının kalitesine etkileri incelenmiştir. Saray helvası numuneleri 25 ve
35°C’de %22-90 arasında farklı bağıl nemlerde denge nemine ulaşılıncaya kadar
depolanmıştır. Üründeki kalite değişimlerini belirlemek amacıyla, depolama
öncesi ve sonrasında nem içeriği, su aktivitesi, sertlik, oksidasyon düzeyi,
renk ve X-ışını kırınımı ölçümleri yapılmıştır. Saray helvasının adsorpsiyon
izotermleri belirlenmiştir. Taze saray helvasının su aktivitesinin 0.21 olduğu
ve camsı halde bulunduğu saptanmıştır. Saray helvasının camsı yapısının 25°C’de %54 ve 35°C’de %32 bağıl nemde korunmadığı
ve hal değişimi sonucunda kristal yapı oluştuğu gözlenmiştir. Her iki
sıcaklıkta da bağıl nemin artmasıyla sertlikte önce bir artış daha sonra bir
azalış gözlenmiştir. Bağıl nem ve sıcaklık arttıkça üründe Maillard reaksiyonu
sonucunda renk değişimi ve oksidasyon sonucunda TBARS değerinde artış meydana
gelmiştir.
A rare cause of postpartum acute hyponatremia

Published: March 2019

A previously healthy 24-year-old female underwent an emergent caesarean section without a major bleeding described. During the first post-operative days (POD) she complained of fatigue, headache and a failure to lactate with no specific and conclusive findings on head CT. On the following days, fever rose with a suspicion of an obstetric surgery-related infection, again with no evidence to support the diagnosis. On POD5 a new-onset hyponatremia was documented. The urine analysis suggested SIADH, and following a treatment failure, further investigation was performed and demonstrated both central hypothyroidism and adrenal insufficiency. The patient was immediately treated with hydrocortisone followed by levothyroxine with a rapid resolution of symptoms and hyponatremia. Further laboratory investigation demonstrated anterior hypopituitarism. The main differential diagnosis was Sheehan’s syndrome vs lymphocytic hypophysitis. Brain MRI was performed as soon as it was available and findings consistent with Sheehan’s syndrome confirmed the diagnosis. Lifelong hormonal replacement therapy was initiated. Further complaints on polyuria and polydipsia have led to a water deprivation testing and the diagnosis of partial central insipidus and appropriate treatment with DDAVP.

Learning points:

Sheehan’s syndrome can occur, though rarely, without an obvious major post-partum hemorrhage.

The syndrome may resemble lymphocytic hypophysitis clinically and imaging studies may be crucial in order to differentiate both conditions.

Hypopituitarism presentation may be variable and depends on the specific hormone deficit.

Euvolemic hyponatremia workup must include thyroid function test and 08:00 AM cortisol levels.

Objetivo. Interpretar los relatos de profesores sobre la enseñanza y específicamente sobre la evaluación de los aprendizajes en la carrera de Psicología de la Universidad Nacional de Mar del Plata.Metodología. Se optó por un enfoque cualitativo desde una perspectiva narrativa concentrada en la comprensión de los significados que los participantes de la investigación otorgan a las prácticas evaluativas. Para recolección de datos se privilegió la técnica de entrevistas semiestructuradas combinadas con materiales, instrumentos y prácticas de evaluación de los aprendizajes elaborados y empleados por los profesores seleccionados. El diseño y la puesta en práctica de los sistemas de evaluación propuestos por cada uno de los docentes entrevistados tienden a ligarse a las valoraciones particulares que cada uno de ellos verbaliza sobre la evaluación de los aprendizajes.Resultados. Variables como la complejidad, la articulación y el trazado de las formas de evaluación son distintas en función de que las mismas sean consideradas de mayor o menor importancia dentro de las actividades pedagógico docentes. Reconocemos además una recurrencia similar donde evaluación, enseñanza y aprendizaje suceden casi en simultáneo y los cambios en las prácticas refieren a modificaciones más amplias desde el currículo y la didáctica.
Урбанонимы в украинском и английском сленге: к вопросу об эквивалентности в переводе
Authors: Бондаренко Екатерина

[full article and abstract in Russian; abstract in English]

This article investigates the informal verbalizations of urban place names; it also questions the hypothesis of their potential untranslatability. The concept of slang is based on the assumption that slang acts as a linguistic channel for liberating carnivalesque laughter. The most numerous lexical fields (presumably most important for the carnivalesque worldview) are those denoting entertainment establishments (brothels, night clubs, cafes), prisons and hospitals. Humankind resorts to substandard communication to state the predominance of primeval instincts, a negative relation to the dominant value system with its restrictions. Mocking values and norms, physiological deficiency, gender or racial peculiarities is the essence of slang as a constituent of humour culture. Slang is a revolt against hierarchy. It relieves tension without endangering the stability of the society. Lexical semantic analysis of slang toponyms shows the potential possibility of adequate comparing and translating of place names in both directions.
Raganos ir burtininkai lietuvių mitologinėse sakmėse ir jų atitikmenys rusų ir anglų kalbose

[full article and abstract in Lithuanian; abstract in English]

This article aims to find cultural equivalents for a group of Lithuanian mythological creatures, namely, magical people, including wizards, witches, sorcerers, etc. in English and Russian languages. Therefore, first, different sources of folkloric translation and its specific issues were consulted, which created the possibility for discussion of some cultural aspects as well as links between Lithuanian, Slavic and Celtic folklore. Second, a comparative analysis of the named mythological creatures in Lithuanian, Russian and English languages and cultures was carried out. The results of the analysis have shown which names of these creatures might be considered exact cultural equivalents and which of them are only partial analogs. Such information is useful not only when choosing a domestication strategy, but for a foreignization strategy as well because these equivalents can be used both in the translation text itself and in additional extratextual comments.

The conclusions given at the end of this article and the provided table, where specific translation suggestions are given, may be of practical importance for translators or authors writing about Lithuanian mythology and folklore for English or Russian speaking readers.

AIMS: To verify the impact of self-perceived health on the chance of developing urinary incontinence in very-old.METHODS: This is a cross-sectional and analytical study with elderly individuals aged 90 years and over. The statistical and analytical variables (sex, marital status, continence, age, depressive symptoms, cognition, comorbidities and ability to perform activities) were analyzed analytical and descriptive statistics (frequencies, mean and standard deviation, univariate and health self-perception adjusted logistic regression analysis).RESULTS: There were 182 participants, 71% women. The previous diagnosis of depression, the score of depressive symptoms and the percentage of ease for functional and basic activities were related to self-perception of health (p<0.05). The loss of urine, however, was not related to self-perceived health. The self-perception of health influenced the effect of the variables previous diagnosis of depression, number of depressive symptoms, Mini-Mental State Examination score and number of comorbidities on the chance of urinary incontinence in thepresence of these variables. Males, widowhood and ease of performance of basic and functional activities were significantly related to urinary incontinence regardless of the adjustment of health self-perception.CONCLUSIONS: There was no relationship between urinary incontinence and health self-perception. However, health self-perception influenced the effect of sociodemographic and clinical variables on the chance of having urinary incontinence.

The tongue flap is a hardy flap that is routinely utilized by oral and maxillofacial surgeons to cover intraoral defects. It has not been previously described as a method for keratinized soft tissue coverage in conjunction with dental implant placement. In this article, we describe use of a tongue flap in the closure of a chronic anterior maxillary dehiscence and to provide keratinized soft tissue coverage for anterior dental implants.
Inhibition of Serotonin Synthesis May Have Antitumor Activity? Long-Term Efficacy in a Patient with Gastrointestinal Neuroendocrine Tumor
Authors: Molina-Cerrillo Javier , Grande Enrique , Alonso-Gordoa Teresa
Published: March 2019

In this article, we propose, based on a clinical case, the potential antitumor effect related to the inhibition of serotonin in neuroendocrine tumors (NETs). Currently, the only drug that exists for the symptomatic treatment of carcinoid syndrome refractory to somatostatin analogues is telotristat, based on its pivotal study, the TELESTAR trial. Based on the existing preclinical rationale, it seems that the inhibition of serotonin may have an antitumoral role in NETs. Briefly, serotonin may act as an autocrine growth factor of NETs, and it may also play an immunomodulatory role by enhancing macrophage polarization to an immunotolerant M2 phenotype. To our knowledge, this rationale for the possible antitumor effect of serotonin in NETs has not yet been published in the literature.
