Authors: Fernandez Fernandez Francisco , Eberhardt Oliver , Schröter Steffen , Wirth Thomas , Ihle Christoph 
Published: September 2019

AbstractBackground Tibial tubercle avulsion fractures are rare, they represent less than 1% of all physeal fractures. Compared to monolateral tibial tubercle avulsion fractures, bilateral occurrence is even rarer. The purpose of this study is to report about the so far largest group of bilateral avulsion fractures and to compare them to unilateral fractures as well as to current literature.Method All patients who suffered from bilateral tibial tubercle fractures between January 2009 and March 2019 were included. All medical records and radiographs were reviewed and a clinical follow-up was performed. The examined criteria were age, gender, mechanism of injury, classification, risk factors, complications, management and outcomes. Clinical outcome was measured using the well established Tegner activity scale and Lysholm-Gillquist score. The same criteria were analyzed in a literature review of bilateral tibial tubercle fractures to compare our results to available literature.Results We found four children with bilateral tibial tubercle avulsion fractures. All patients were male with a mean age of 14.5 ± 0.7 years (13 – 15). Mean follow-up examination was 13.6 ± 6.5 months (8 – 29) after surgery. The avulsions occurred during jumping activities in all cases. All children could no longer stand or move because of sudden pain in the knee. We found type IV fractures in three cases, type III fractures in four cases and one type V fracture according to the Ogden classification. All children were treated by open or closed reduction and stabilization with screws or K-wires. Follow-up showed complete fracture healing without complications in all patients. There were no changes in Tegner activity scale and Lysholm-Gillquist Score and knee function comparable to prior to the accident was achieved in all cases.Conclusion Good clinical results without restrictions regarding function of the knee joint can be achieved by direct operative treatment of bilateral tibial avulsion fractures. A reduction in sporting activity has not to be expected. There were no differences between bilateral or unilateral tibial tubercle avulsion fractures.

Authors: Cardona Maya Walter D. 
Published: September 2019

ResumenDeterminar el efecto del glifosato sobre la calidad seminal en humanos a través de una revisión sistemática. Se realizó una búsqueda de la literatura en dos bases de datos (Pubmed y Scopus) de los terminos glyphosate/gliphosate/Roundup/yerbimat y sperm/“male reproductive tract”. Los criterios de selección permitieron analizar tres artículos sobre el efecto del glifosato sobre los espermatoozides humanos. Se observó un efecto de negativo del glifosato sobre los espermatoozides humanos (movilidad, actividad mitocondrial y DNA). Aunque son pocos los artículos que evalúan el efecto del glifosfato sobre la calidad seminal, todos concluyen en sus repercusiones negativas. Investigaciones sobre el tema se requieren especialmente ahora que el Gobierno Nacional pretende implementar su uso.

AbstractFor the first time, we report about two extremely low birth weight infants who were born at 25 and 22 weeks' gestation and who survived functional pulmonary atresia (fPA) with normal intracardiac anatomy. A slow, reflected, and bimodal blood flow pattern in the pulmonary artery (both cases) and the presence of pulmonary regurgitation (1 case) were useful for diagnosing fPA. Timely use of lipo-prostaglandin E1 to maintain adequate pulmonary flow and reduce pulmonary arterial resistance and sodium bicarbonate to improve acidosis were effective treatments to attain forward flow. As optimal management is essential for the intact survival of extremely early preterm infants and the accurate diagnosis of fPA is difficult without the awareness of the disease entity, our cases underline the importance of recognizing that fPA can occur even in extremely low birth weight infants with normal intracardiac anatomy.
Late Ordovician to early Silurian calc-alkaline magmatism in the Xiemisitai Mountains, northern West Junggar: a response to the subduction of the Junggar-Balkhash Ocean

Published: September 2019

The Early Palaeozoic tectonic evolution of northern West Junggar is essential for understanding the tectonic framework and accretionary processes in the southwestern segment of the Central Asian Orogenic Belt. However, its evolutionary history is controversial due to insufficient pre-late
Silurian magmatic data. In order to clarify this issue, we conducted geochronological, geochemical, and Sr-Nd-Hf isotope analyses on samples from the Dengdeer and Maodun complexes in the Xiemisitai Mountains of Boshchekul-Chingiz (BC) arc, northern West Junggar. LA-ICP-MS zircon U-Pb dating
yielded ages ranging from 445 Ma to 429 Ma, revealing the Late Ordovician to early Silurian magmatic events in northern West Junggar. The dioritic and metaluminous Dengdeer complex has high Mg# (49.5–52.9), moderate La/Yb (11.0–12.3), and low initial 87Sr/86Sr
(0.70324–0.70410) and εNd(t) (+3.7 to +4.5). This complex exhibits variable zircon εHf(t) (+11.31 to +17.62), young Hf model ages (470–440 Ma), and appears to have been produced by differentiation of melts from metasomatized mantle. The intermediate to felsic, metaluminous
to weakly peraluminous Maodun complex has abundant enclaves and inherited zircons. This complex seems to have fractionated from mantle- and crustal-derived magma mixing with some crustal contamination, based on its high Mg# (36.6–49.5), low Sr/Y (8.7–29.6), Nb/Ta (8.3–13.9),
initial 87Sr/86Sr (0.70377) and εNd(t) (+4.0 to +4.2), and variable zircon εHf(t) (+11.59 to +15.21). The Dengdeer and Maodun samples are high-K calc-alkaline, rich in hydrous minerals, Rb, Th, and LREEs, depleted in Nb, Ta, and Ti, and show decoupling Hf-Nd isotopic
signatures. These characteristics indicate that their source had been modified by melts from slab sediments. After combining our data with previous observations, we conclude that a trench-ward migration of an arc-back-arc system occurred during the Late Ordovician to early Silurian in northern
West Junggar, while the Dengdeer and Maodun complexes were related to subduction-accretionary processes of the Junggar-Balkhash oceanic slab beneath the BC arc.

Abstract
Geological, mineralogical, petrochemical and geochronological data are considered for the Khairkhan dunite-troctolite-gabbro massif in the Lake zone of Western Mongolia. The massif intrude the Lower Cambrian molasse stratum and intruded by the Middle Cambrian diorite-plagiogranite bodies (507 Ma). Mineralogical, petrographic and geochemical data show typical suprasubduction characteristics: high An component of plagioclases with increased iron content of olivines, high whole-rock alumina content, low contents of titanium and alkalis, Ta, Nb, Zr and Hf minima. The layered series is characterized by a layers of orbicular gabbros, which can be considered as gabbro-gabbro mingling. At the same time, high-temperature viscous-plastic deformations are characteristic of the layered series, which cover the entire volume of the intrusion. These observations, together with geological and geochronological data related to the melting of the suprasubduction mantle in the Cambrian-Ordovician time, allow treating the Khairkhan massif as an example of syncollisional stratified gabbroids.

Authors: Semiryakov A S , Grinev O M , Bestemianova K V , Grinev R O 
Published: September 2019

Abstract
The object of the present study are the ore-bearing breccias of the worked-out lower-middle Devonian gold-silver barite-polymetallic Zmeinogorsky deposit belonging to the cognominal ore district and the conserved massive sulfide Chekmar deposit belonging to the Leninogorsk ore district. Both ore districts occupy an adjacent position within the northeastern depression zone of the Ore Altai megatrough. A brief structural and geological description of near-fault ore-bearing breccias, which developed within the peripheral parts of the deposits, is given. Analysis of petrographic composition of breccia fragments and their cementing material allowed to define barite-quartzite breccias of the Zmeinogorsky deposit and pyritized adularia-quartz metasomatites formed upon acidic igneous rocks and greenschists of the Chekmar deposit. Results of mineralogical studies with use of raster electron microscope show that there are ore minerals microinclusions in the detrital material and cement of breccias. Barite-quartzite breccias of Zmeinogorsk deposit contain barite, galena, Hg and Sb containing polymineral formations, tetrahedrite-boulangerite, bromargyrite, leucoxene. Microquartzites of these breccias mostly consist of quartz. Chekmar deposit ore breccias detrital material contains pyrite, barite, arsenopyrite, galena, sphalerite, zircon, titanite, leucoxene and REE minerals. Quartzitic compound of these breccias is cryptocrystalline and consists of quartz and adularia with admixtures of sericite and pyrite. Due to results obtained by use of SEM it was stated that barite, sulfides and sulfosalts of breccias contain noticeable amounts of dissipated Au, Pd, Pt, Ir. ICP-MS results confirm that studied ore breccias contain such noble metals as Au, Ag, Pd, Pt. Moreover, noble metals contents in Zmeinogorsk deposit breccias reach industrial standards while noble metals of Chekmar deposit ores can be extracted along with the processing of basic massive sulfide ores. Further study of ore breccias is important as these breccias can be considered as a noble metals containing subformation among polymetallic ores of Ore Altai.

Abstract
The batik industry potentially pollutes the environment with the liquid waste of synthetic dyes. Cleaner production approach can be implemented to minimize pollution concerning environmental, technical as well as economic aspects. This study was aimed to analyze the strategy for implementing a cleaner production concept in the batik industry located in Bogor concerning technical, environmental and financial aspects. The methods used in this study were a quick scan for waste identification along with with the production flow, fishbone diagram for problems’ mapping, and analytical hierarchy process (AHP) for selecting the best strategy. The quick scan result indicated that dyeing, soaking and rinsing processes were main contributors of the dye waste. The use of natural dyes was considered as the best strategy to achieve environment-friendly and sustainable batik industry, whereas the production process and batik industry were the most important factor and actor, respectively. The use of bucket under drying fabrics to retain falling water is recommended as the best option, with low investment cost and a payback period of 6 months. Sustainable batik industry through institutional development is also recommended for optimizing the use of resources to provide natural dyes, as well as skillful entrepreneurs, and workers of dyes-extracting and batik industries.
Landscape structure and parasitoid diversity as measures of sustainable landscape

Published: September 2019

Abstract
Complexity and structure of a landscape influence the presence of insect parasitoids in agricultural landscapes. Landscape structures are often formed from semi-natural habitat fragmentation, which can reduce the richness and abundance of insect parasitoid and affect their ability to suppress pest population. This study was aimed to study the effect of landscape structure on the diversity and abundance of insect parasitoids in long beans fields. In six agricultural regions, landscape parameters were calculated, i.e class area (CA), a number of patches (NumP), and mean patch size (MPS). Insect samplings were conducted using transect methods and direct collection. Results of landscape complexity did not affect the species richness of parasitoid, but it did affect the species composition. The results showed that the higher the CA of the tree, the higher the percentage of parasitization, but the higher the CA of agriculture, the lower the percentage of parasitization. This shows that there are landscape parameter indicators that can be used as a key to see the presence of parasitoids so that they can provide an indication of sustainability. Therefore, landscape structure must consider the importance of landscape management habitats for the conservation of natural enemies especially insect parasitoid as a biological control agent to create sustainable landscapes.
Materials selection rules for optimum power factor in two-dimensional thermoelectrics
Authors: Kommini Adithya , Aksamija Zlatan 
Published: September 2019

Abstract
Two-dimensional (2D) materials have emerged as the ideal candidates for many applications, including nanoelectronics, low-power devices, and sensors. Several 2D materials have been shown to possess large Seebeck coefficients, thus making them suitable for thermoelectric (TE) energy conversion. Whether even higher TE power factors can be discovered among the ≈2000 possible 2D materials (Mounet et al 2018 Nat. Nanotechnol.
13 246–52) is an open question. This study aims at formulating selection rules to guide the search for superior 2D TE materials without the need for expensive atomistic simulations. We show that a 2D material having a combination of low effective mass, higher separation in the height of the step-like density of states, and valley splitting, which is the energy difference between the bottom of conduction band and the satellite valley, equal to 5 k

B

T will lead to a higher TE power factor. Further, we find that inelastic scattering with optical phonons plays a significant role: if inelastic scattering is the dominant mechanism and the energy of the optical phonon equals 5 k

B

T, then the TE power factor is maximized. Starting from a model for carrier transport in MoS2 and progressively introducing the aforementioned features results in a two-orders-of-magnitude improvement in the power factor. Compared to the existing selection rules or material descriptors, features identified in this study provide the ability to comprehensively evaluate TE capability of a material and helps in identifying future TE materials suitable for applications in waste-heat scavenging, thermal sensors, and nanoelectronics cooling.
Female preferences when female condition and male ornament expression vary
Authors: Reyes-Ramírez Alicia , Rocha-Ortega Maya , Córdoba-Aguilar Alex 
Published: September 2019

Abstract
Variation in the condition of females can affect their mate preferences. This may explain variation in the expression of male ornaments. We tested these ideas in the mealworm beetle (Tenebrio molitor), a species in which females choose males based on their pheromones. We modified female condition using diets that differed in proteins and carbohydrates. We then allowed females to choose among males in which we had previously modified pheromone expression (either by varying diets as in females, or by fungal infection). Females were offered a choice between two males, both of which had been fed the same diet as the female, but which differed in whether they were infected or not. We repeated the same diet and infection treatments to determine whether poor (lower carbohydrate) diets decrease survival in both sexes. There was no effect of female diet on mate choice, but the infection state of the male did have an effect, with infected males being preferred. It is possible that infected males invest their resources in producing pheromones rather than attacking the pathogen. Both sexes, independent of infection, had higher survival when fed carbohydrate-rich diets. The results showed no effect of female condition on their preferences, at least not prior to copulation.
Systematic Review: Clinical Utility of Gastrointestinal Ultrasound in the Diagnosis, Assessment and Management of Patients With Ulcerative Colitis
Authors: Smith Rebecca L , Taylor Kirstin M , Friedman Antony B , Gibson Robert N , Gibson Peter R 
Published: September 2019

Abstract

Background and Aims
Gastrointestinal ultrasound is useful in the assessment of patients with Crohn’s disease, but its application in ulcerative colitis [UC] is less well established. Here we systematically review the role of gastrointestinal ultrasound in patients with UC.

Methods
Searches of the PUBMED and EMBASE databases were performed with the following search strategy: [ultrasound OR sonography] AND [intestinal OR bowel] AND [ulcerative colitis OR inflammatory bowel disease]. The final search was performed in August 2019.

Results
Of 6769 studies identified in the search with a further two studies found from other sources, 50 studies met the inclusion criteria. Increased bowel wall thickness and detection of increased blood flow by colour Doppler were the most often applied criteria for defining disease activity and distribution. When compared with other reference investigations, gastrointestinal ultrasound accurately determined disease extent, severity and response to medical therapy. While further information can be obtained from haemodynamic measurements of the abdominal vessels and contrast-enhanced ultrasound, their clinical value was uncertain. Likewise, hydrocolonic sonography has few advantages over standard gastrointestinal ultrasound examination. Of several scoring systems proposed, there is disparity between the measures and a general lack of validation. There has been limited application of gastrointestinal ultrasound in acute severe ulcerative colitis with toxic megacolon, and, while performing well in children, normal limits differ from those in adults.

Conclusion
Current evidence indicates that gastrointestinal ultrasound has utility in the non-invasive assessment of patients with UC. Continued advances in technology with better image resolution, validation of scoring systems and application at the point of care by gastroenterologists are likely to contribute to increased use of gastrointestinal ultrasound in routine clinical practice.
Echocardiographic and radiological evaluation of an unusual aortic root mass in an asymptomatic patient: a case report
Authors: Memtsas Vassilios , Sharma Naveen , Lynch Mary 
Published: September 2019

Abstract

Background
Incidental echocardiographic findings in the asymptomatic patient can present a diagnostic challenge to the clinician. This case report demonstrates that both natural occurring and iatrogenic causes should be considered in the differential diagnosis of isolated aortic root masses.

Case Summary
A patient presenting for a routine transthoracic echocardiogram to evaluate worsening breathlessness on exertion is found to have an unexpected aortic root mass. Due to the unusual appearances of the aortic root mass, it is further evaluated with additional imaging modalities, including transoesophageal echocardiogram and computed tomography coronary angiography. The mass is fully characterized following the computed tomography coronary angiography as a right coronary artery stent, from a previous coronary angioplasty, protruding into the lumen of the aortic root. No further investigation or intervention is required.

Discussion
A wide differential diagnosis of focal aortic root masses is presented. The non-invasive characterization of such masses can present a challenge. This case demonstrates the value of a multimodality imaging approach, including transthoracic, transoesophageal echocardiography, and computed tomography coronary angiography, in the evaluation of such masses.
