Authors: Widyastuti Andriani , Aji Ludi Parwadani 
Published: October 2019

<strong>Some Aspects of Reproduction in Conch Lambis lambis of Yenusi Coastal Waters, Biak.</strong> Lambis lambis is a very popular conch species that has been harvested in all sizes encountered. This condition is very alarming because in the long term, its existence in nature will be reduced because there is no chance to reproduce naturally. This study aims to determine the sex ratio and gonad maturity levels of L. lambis in Yenusi waters, so the appropriate time of harvest can be arranged. Samples were collected every month from January to December 2013. Testing and histological analysis were performed in the laboratory. Samples collected were 99 individus with the number of males 45 individus and females 54 individus. The sex ratio of males and females was 1.0:1.2. Gonad maturity level found included all four stages of gonadal development, from TKG I to TKG IV. Gonadal development showed the process of formation and maturation, and the spawning occured throughout the year, with peak spawning in January until March 2013. The size of the shell length obtained ranged from 4.55 to 13.72 cm indicating over-exploitation. Due to the custom local where residents harvested the conches in all sizes found, sustainable management strategies are urgently needed, including moratorium period when L. lambis is at the peak of spawning, and harvest should only be performed on adult individuals with a minimum shell size of 7 cm, while observing the thickness of the shell and marginal digitations have been formed. <br /><br />

Published: October 2019

<strong>Mangrove Mapping of The Lease Islands, Maluku Province Using Multi-Temporal And Multi-Sensor Of Landsat Satellite Images.</strong> Mangrove mapping in the Lease Islands, Maluku Province has been done, but using only a single date satellite image. Therefore, it is difficult to know the dynamics of their changes. The aim of this study is to map mangroves every 5 year (1985-2015) using multi-sensors (MSS, TM, ETM+ and OLI) of Landsat and field data. Supervised classification using maximum likelihood was used for classifying mangrove and other habitats, and counting their areas. Results showed that mangrove in the Saparua and Nusalaut Islands, consisted of 22 and 13 species, respectively, with the longest distribution along the cost line of Tuhaha Bay due to freshwater supplay from the surrounding river, while the rest are grown in the hardy reef flat substrates. The mean overall acurracies of the maps was good enough (74.7%), except for one Landsat-5 TM and Landat-8 OLI because of the influences of cloud cover or haze. During 30 years, the areas of mangrove are relatively stable since they are protected by local wisdom called "Kewang". The highest bias of 11.4% that made the areas of mangrove increase or decrease was not due to the utilization or conversion of mangrove, but mainly due to the influences of cloud cover/haze and the geometric differences among Landsat sensors. In the near future, the OBIA method should be try, because it seems to be able to produce mangrove maps with better accuracy.

Published: October 2019

<p>Jakarta Bay is an estuarine ecosystem and facing the small island groups of Seribu Island. Jakarta Bay is known as nursery ground for many marine biotas, determined by numerous numbers of meroplankton. The distributions of meroplankton are highly influence by environmental conditions of Jakarta Bay and Seribu Islands. This research objective was to analyze the habitat preferences of some meroplankton groups such as shrimp, mollusk, crab and fish larvae in Jakarta Bay and Southern Seribu Islands. Fish larvae sampling was conducted in 13 stations that categorized into estuarine and small island stations in Jakarta Bay and Southern Seribu Island, combination of seven estuarine stations and six small island stations. The results found that there was a variation on the distribution and composition of meroplankton in sampling area. There were six groups of marine meroplankton, namely shrimps, mollusk, crabs, fish, jelly fish and squid larvae in Jakarta Bay and Seribu Island. The abundance of shrimp, mollusk and fish larvae is higher in April than August. The abundance of crab larvae is higher in August than April, while the others are found in small number both in April and August. Shrimps, fish and mollusks larvae have no specific preferences in habitat used, however they mostly used small island stations as their habitat compare to estuary, which has high temperature and salinity <br /><br /></p>
The Impact of Obesity and Type 2 Diabetes on Chronic Liver Disease
Authors: Younossi Zobair M. , Henry Linda 
Published: October 2019

Abstract
The growing global epidemic of obesity and type 2 diabetes mellitus (T2DM) has led to the increasing prevalence of nonalcoholic fatty liver disease. In addition, the presence of obesity and T2DM has been shown to increase the likelihood of adverse outcomes in patients with chronic liver disease. In a study by Harris et al., a combination of obesity and T2DM was associated with an increased risk for higher liver stiffness, as measured by transient elastography. It is possible that public health and clinical intervention targeting these components of metabolic syndrome can lead to improved outcomes of subjects with nonalcoholic fatty liver disease and other chronic liver diseases.
Cold Snare Polypectomy in Patients Taking Dual Antiplatelet Therapy: A Randomized Trial of Discontinuation of Thienopyridines
Authors: Won Ma Dae , Kim Joon Sung , Ji Jeong-Seon , Kim Byung-Wook , Choi Hwang 
Published: October 2019

INTRODUCTION:
Cold snare polypectomy (CSP) is a safe and effective method for removing polyps ≤10 mm. The aim of this study was to compare the risk of clinically significant bleeding and thromboembolic events after CSP between stopping and continuing thienopyridines in patients taking dual antiplatelet therapy (DAPT).

METHODS:
The study was a single-center, noninferiority, and randomized controlled study involving patients who received colonoscopy from October 2015 to October 2016. Patients receiving DAPT with polyps ≤10 mm were randomly assigned to either the DAPT group (patients continued DAPT) or the aspirin group (patients discontinued thienopyridines for 1 week). Primary outcome was clinically significant bleeding. Secondary outcomes included intraprocedural bleeding, nonsignificant hematochezia, and occurrence of thromboembolic events.

RESULTS:
Forty-two patients with 104 eligible polyps were allocated to the DAPT group, and 45 patients with 101 eligible polyps were allocated to the aspirin group. Patient demographic characteristics including size, location, shape, and pathology of the removed polyps were similar in the 2 groups. Intraprocedural bleeding and nonsignificant hematochezia rates were also similar between the 2 groups (4.8% vs 2.2%, P = 0.608; 19.0% vs 8.9%, P = 0.170). No thromboembolic event occurred in either group. Only 1 patient (2.4%) in the DAPT group showed clinically significant bleeding. No significant bleeding was found in the aspirin group.

DISCUSSION:
Clinically significant bleeding rate after CSP for polyps ≤10 mm in patients continuing to take DAPT was 2.4%. Therefore, CSP is a safe method for removing small polyps even in patients taking DAPT (ClincialTrials.gov number, NCT02865824).

Authors: Белова Юлия Юрьевна , Фадеева Ирина Михайловна 
Published: October 2019

Виртуальные социальные сети мгновенно реагируют на происходящие в обществе процессы, в них отражаются актуальные практики поведения людей, в том числе по отношению к употреблению алкоголя. Обсуждение процесса алкоголепотребления в социальных сетях характеризуется экспрессивной коммуникацией, особенно в комментариях интернет-пользователей.
Цель исследования состоит в выявлении смысловой структуры репрезентации повседневного потребления алкоголя в дискурсе виртуальных социальных сетей. С помощью качественного анализа комментариев пользователей социальных сетей определены ведущие смысловые модели репрезентации, отражающие доминирующие практики повседневного потребления алкоголя. В ходе исследования проанализировано 10195 комментариев, опубликованных 9 000 российскими пользователями популярных социальных сетей: «ВКонтакте», «Одноклассники», Facebook, Google+, Instagram, — за период с 16 марта по 16 апреля 2018 г. Для отбора комментариев использовалась информационно-аналитическая система «Медиалогия».
По результатам исследования сделан вывод о наличии множественности смысловых моделей репрезентации повседневного потребления алкоголя, отраженных в пространстве социальных сетей. Они позволили выделить основные алкогольные дискурс-практики и социокультурные черты потребления алкоголя, маркеры его общественной нормативности.
Исследование показало, что обсуждение потребления алкоголя в социальных сетях репрезентирует следующие социокультурные смыслы: социальная нормативность, доступность, обыденность, стереотипизированность, стандартизация, сакральность, социокультурная укорененность. Многообразие проалкогольного контента в социальных сетях свидетельствует о высокой значимости этого феномена в социальном пространстве и представлениях людей, указывает на наличие социокультурных характеристик современной интернет-коммуникации, в рамках которой формируются свой метаязык и соответствующие смыслы, требующие изучения на междисциплинарном уровне.

Использование интернета и культурное потребление в странах Европы: сравнительный анализ
Authors: Корсунова Виолетта Игоревна , Волченко Олеся Викторовна 
Published: October 2019

В работе анализируется связь между онлайн- и офлайн-практиками культурного потребления в странах Европы. Существует множество исследований, рассматривающих связи между использованием интернета и офлайн-жизнью пользователей, однако их результаты разнятся: с одной стороны, интернет воспринимается как «заместитель», вытесняющий традиционные формы социальных взаимодействий; c другой стороны, в ряде работ показывается, что, напротив, интернет положительно связан с социальной активностью, разнообразием форм досуга и является одной из составляющих нового культурного капитала. Вместе с тем в существующей литературе недостаточно изучена связь между онлайн-практиками досуга и соответствующими традиционными практиками досуга. В данной статье на примере культурных практик посещения кинотеатров, концертов и оперы рассматривается эффект использования интернета в культурных целях. В частности, проанализирована связь между использованием интернета для скачивания/просмотра фильмов, а также скачивания/прослушивания музыки и соответствующих офлайн-практик. На данных Евробарометра 79.2 (2012-2013 гг.) установлена положительная связь между офлайн-практиками и соответствующими практиками онлайн. В то же время данная связь оказывается зависимой от иных характеристик, таких как возраст, размер населенного пункта и уровень развития страны.

Findings of metabolic bone disease in infants with unexplained fractures in contested child abuse investigations: a case series of 75 infants
Authors: Miller Marvin , Stolfi Adrienne , Ayoub David 
Published: October 2019

Abstract

Background
Infants who present with multiple unexplained fractures (MUF) are often diagnosed as victims of child abuse when parents deny wrongdoing and cannot provide a plausible alternative explanation. Herein we describe evidence of specific and commonly overlooked radiographic abnormalities and risk factors that suggest a medical explanation in such cases.

Methods
We evaluated such infants in which we reviewed the radiographs for signs of poor bone mineralization. We reviewed medical, pregnancy and family histories.

Results
Seventy-five of 78 cases showed poor bone mineralization with findings of healing rickets indicating susceptibility to fragility fractures that could result from a wide variety of causes other than child abuse. We found risk factors that could explain the poor bone mineralization: maternal and infant vitamin D deficiency (VDD), decreased fetal bone loading, prematurity and others. Most infants had more than one risk factor indicating that this bone disorder is a multifactorial disorder that we term metabolic bone disease of infancy (MBDI). Maternal and infant VDD were common. When tested, 1,25-dihydroxyvitamin D levels were often elevated, indicating metabolic bone disease.

Conclusions
Child abuse is sometimes incorrectly diagnosed in infants with MUF. Appreciation of the radiographic signs of MBDI (healing rickets), risk factors for MBDI and appropriate laboratory testing will improve diagnostic accuracy in these cases.

Abstract
The phytochemical study of the roots, leaves and twigs of Penianthus camerounensis Dekker (Menispermaceae) has led to the isolation and the characterization of 20 compounds. A ceramide, camerounamide (1), and a furoclerodanediterpenoid, camerounin (2), have not been described previously, while the compounds xylopic acid (3), syringaresinol (4), iso-propylmethylcyclohexa-1,4-diol (5), 1-(28-hydroxyoctacosanoyl)glycerol (6), scoparone (7), friedelin (8), friedelanol (9) and betulinic acid (10) are being reported for the first time from the genus Penianthus alongside 10 known compounds (11–20). Chemical structures were determined using 1D- and 2D-NMR spectroscopy, MS and chemical analysis. Their chemotaxonomic importance is discussed.
Magnesium Ferrite (MgFe2O4) Nanoparticles for Photocatalytic Antibiotics Degradation
Authors: Becker Anna , Kirchberg Kristin , Marschall Roland 
Published: October 2019

Abstract
Removal of drug residuals in waste water by easy-separable catalysts is of fundamental interest for clean water provision by photocatalytic water remediation. Here, we present our studies to use the ferrimagnetic earth-abundant absorber MgFe2O4, prepared by microwave-assisted synthesis, for the photocatalytic removal of methylene blue and tetracycline from model solutions under dark and sunlight conditions. The surface of MgFe2O4 has a strong influence on the tetracycline removal, while more than 75% tetracycline degradation can already be achieved in 2 h with unmodified MgFe2O4. Using surface-modified MgFe2O4 nanoparticles, the adsorption of tetracycline is even more pronounced, however goes in line with release of the surface capping agent.
Differential Adaptation in Azimuth and Elevation to Acute Monaural Spatial Hearing after Training with Visual Feedback
Authors: Zonooz Bahram , Van Opstal A. John 
Published: October 2019

AbstractSound localization in the horizontal plane (azimuth) relies mainly on binaural difference cues in sound level and arrival time. Blocking one ear will perturb these cues, and may strongly affect azimuth performance of the listener. However, single-sided deaf listeners, as well as acutely single-sided plugged normal-hearing subjects, often use a combination of (ambiguous) monaural head-shadow cues, impoverished binaural level-difference cues, and (veridical, but limited) pinna- and head-related spectral cues to estimate source azimuth. To what extent listeners can adjust the relative contributions of these different cues is unknown, as the mechanisms underlying adaptive processes to acute monauralization are still unclear. By providing visual feedback during a brief training session with a high-pass (HP) filtered sound at a fixed sound level, we investigated the ability of listeners to adapt to their erroneous sound-localization percepts. We show that acutely plugged listeners rapidly adjusted the relative contributions of perceived sound level, and the spectral and distorted binaural cues, to improve their localization performance in azimuth also for different sound levels and locations than those experienced during training. Interestingly, our results also show that this acute cue-reweighting led to poorer localization performance in elevation, which was in line with the acoustic–spatial information provided during training. We conclude that the human auditory system rapidly readjusts the weighting of all relevant localization cues, to adequately respond to the demands of the current acoustic environment, even if the adjustments may hamper veridical localization performance in the real world.
Dispersão e mobilidade urbana no Brasil: estudo de um aglomerado urbano
Authors: Cordovil Fabíola Castelo de Souza , Barbosa Leonardo Cassimiro 
Published: October 2019

Analisamos as tendências da cidade contemporânea, de expansão e dispersão aliadas à mobilidade urbana, em um aglomerado urbano brasileiro, localizado no noroeste do Paraná, Brasil. Abordamos conceitos de cidade difusa, de dispersão e de fragmentação urbana refletindo sobre as tendências de conformação regional e o papel da mobilidade urbana. Para tanto, investigamos a história da formação do território, analisamos mapeamentos de uso do solo, os eixos regionais e dados de população, de frota e de deslocamento populacional. Observamos que o município polo concentra as atividades econômicas e os movimentos pendulares, cada vez mais dependentes do transporte individual de passageiros. Com a instalação de grandes polos de atração em áreas periféricas, a partir de fluxos regionais que produzem novas centralidades, percebe-se a tendência de abandono do forte caráter polarizador para relações de fluxos mais horizontais.
