Authors: Malik Sadia , Vitales Daniel , Qasim Hayat Muhammad , Korobkov Aleksandr A. , Garnatje Teresa , Vallès Joan 
Published: August 2017

AbstractArtemisia subg. Seriphidium is one of the largest groups within Artemisia, encompassing more than one hundred species, some of them having considerable ecological and economical importance. However, the evolution of subg. Seriphidium has received less attention in comparison to other subgenera of Artemisia, probably, apart from the difficulty of sampling throughout its very large distribution area, because of the low molecular and morphological variability observed in previous studies. Here, we use thorough taxonomic sampling within both Artemisia and subg. Seriphidium to reconstruct the evolutionary history of the subgenus, employing nuclear and plastid DNA sequences as well as various phylogenetic, biogeographic and diversification dynamics tools to analyse the data. Our results show that subg. Seriphidium is not monophyletic, but segregated into two main clades: one large monophyletic group corresponding to the formerly recognised sect. Seriphidium and a second, small clade, phylogenetically distant from the first. Biogeographic and diversification analyses indicate that a rapid radiation of species within sect. Seriphidium occurred in Central Asia during the Miocene‐Pliocene transition. The results of our biogeographic analysis suggest that this diversification process started around the Tian‐Shan, Pamir and Hindu Kush mountain ranges, subsequently expanding into the Eurasian continent. Finally, we uncovered numerous incongruences between taxonomic and genetic information in several sect. Seriphidium species, which could be explained by morphological uniformity, hybridisation and/or incomplete lineage sorting processes.
Coercivity of integral functionals with non-everywhere superlinear lagrangians
Authors: Marcelli Cristina 
Published: August 2017

AbstractWe consider the classical non-autonomous variational problem\text{minimize }\biggl{\{}F(v)=\int_{a}^{b}f(x,v(x),v^{\prime}(x))\,\mathrm{d}%
x:v\in\Omega\biggr{\}},where {\Omega:=\{v\in W^{1,1}(a,b),\,v(a)=A,\,v(b)=B,\,v(x)\in I\}},
when the lagrangian f has non-everywhere superlinear growth, in the sense
that it can vanish at some {x_{0}\in[a,b]}, or {s_{0}\in I}. We prove some
sufficient conditions ensuring the coercivity of the functional F.
As a consequence, when f is convex with respect to the last variable,
the existence of the minimum can be immediately derived.
Sudden fetal death of a co-twin as a complication of intrafetal laser surgery and placenta examination with dye
Authors: Erenel Hakan , Korkmaz Sevim Ozge , Karsli Mehmet Fatih , Ozel Aysegul , Sen Cihat 
Published: August 2017

Abstract
Monochorionic (MC) twin pregnancy is a distinct entity and has certain differences from dichorionic twins due to the unique placental angioarchitecture. It is characterized by twin-to-twin transfusion syndromes (twin oligohydramnios-polyhydramnios sequence and twin anemia-polycythemia sequence), acardiac twinning, selective fetal growth restriction and congenital anomalies. Selective termination is an option in MC twins complicated by selective fetal growth restriction and discordant fetal anomaly. Fetal demise of the co-twin can occur even after uncomplicated surgery. A selective fetal termination using an intrafetal laser was performed in the case of an MC twin pregnancy complicated by twin oligohydramnios-polyhydramnios sequence and hydrocephalus in the donor twin. Fetal demise of the co-twin was observed after surgery. The placenta was examined with dye injections after abortion and showed vascular anastomoses causing unexpected fetal demise.
Perceived Feasibility and Desirability of Entrepreneurship in Institutional Contexts in Transition
Authors: Heilbrunn Sibylle , Itzkovitch Yariv , Weinberg Caren 
Published: August 2017

AbstractWe have scrutinized the role of regulative, normative and cognitive institutional environments on perceived desirability and feasibility of entrepreneurial action by applying the institutional framework to two types of Israel kibbutz cooperative communities. When combining convenient and snowball sampling, entrepreneurial drive indicators were identified among 253 community members in 2010. MANOVA analysis revealed that members of wage differential oriented kibbutzim perceived entrepreneurial action as more feasible but not more desirable than members of egalitarian kibbutzim. This reaffirms the importance of accounting for specific community characteristics when researching aspects of entrepreneurship.

Preimaginal mortality ofMusca domestica(Diptera: Muscidae) due toHabronema muscae(Nematoda: Habronematidae)
Authors: Schuster R. K. 
Published: August 2017

SummaryIn order to study the damage ofHabronema muscae(Carter, 1861) on its intermediate host,Musca domesticaLinnaeus, 1758, fly larval feeding experiments were carried out. For this, a defined number of praeimaginal stages ofM. domesticawas transferred in daily intervals (from day 0 to day 10) on faecal samples of a naturally infected horse harboring 269 adultH. muscaein its stomach. The development ofM. domesticawas monitored until imagines appeared. Harvested pupae were measured and weighted and the success of infection was studied by counting 3rdstage nematode larvae in freshly hatched flies. In addition, time of pupation and duration of the whole development of the flies was noticed. Pupation, hatching and preimaginal mortality rates were calculated and the number of nematode larvae in freshly hatched flies was counted. Adult flies harboured up to 60Habronemalarvae. Lower pupal volumes and weights, lower pupation rates and higher preimaginal mortality rates were found in experimental groups with long exposure to parasite eggs compared to experimental groups with short exposure or to the uninfected control groups. Maggots of the former groups pupated earlier and fly imagines occurred earlier. These findings clearly showed a negative impact ofH. muscaeon the development ofM. domestica. The results are discussed in connection with the destruction of adipose cells in the maggots by developing nematode larvae.

SummaryThe aim of this paper was to study the occurrence of helminths inMus musculusandRattus rattusfrom urban, suburban and rural settlements in Yucatán, Mexico; and to analyse the host factors (e.g. sex) related to helminths’ distribution. Helminths in a total of 279 rodents were surveyed by visual examination of the liver for metacestodes and faecal examination for helminth eggs using the formalin-ethyl acetate sedimentation technique. The cestodesHydatigera taeniaeformis(metacestodes detected in the liver) andHymenolepis diminuta,and the nematodesAspiculurissp.,Nippostrongylus brasiliensis,Syphacia muris,Syphacia obvelata, andTrichuris muriswere identified. InM. musculus, the prevalence of infection withT. murisandH. taeniaeformiswas higher in the rural village compared to those in the suburban neighbourhood. ForR. rattus, a higher prevalence of infection withH. diminutawas found in the urban site compared to that in the suburban site. This study reports the occurrence ofH. diminutaamong rodents living in close proximity to humans, representing a potential public health risk. In addition, this survey increases our understanding of dynamic transmission among intestinal helminths recorded in Yucatán, Mexico.
Morphological and molecular genetic analysis of Synhimantus (Synhimantus) laticeps (Rudolphi, 1819) (Nematoda, Acuariidae) from the barn owl (Tyto alba) and the common kestrel (Falco tinnunculus) in Austria

Published: August 2017

Summary
In the framework of the biodiversity initiative and barcoding project “Austrian Barcode of Life” (ABOL) post mortem examinations of the gastro-intestinal tracts of different species of wild birds were carried out and several adult helminths were retrieved. In the gizzard of two barn owls (Tyto alba) and one common kestrel (Falco tinnuculus) acuariid nematodes belonging to the species Synhimantus (Synhimantus) laticeps (Rudolphi, 1819) were discovered. This report illustrates the identification of this parasitic nematode by morphometric comparison and scanning electron microscopic photographs. Furthermore, genetic identification of individual parasites based on a fragment of the mitochondrial cytochrome c oxidase subunit I (COI) gene and the nuclear 18S ribosomal RNA gene was carried out. This report constitutes the first COI-based DNA barcoding of S. (S.) laticeps and its first record in the barn owl (Tyto alba) in Austria.
The molecular mechanisms involved in lectin-induced human platelet aggregation
Authors: Signorello Maria Grazia , Leoncini Giuliana 
Published: August 2017

AbstractWe have compared the effect of three legume lectins, wheat germ agglutinin (WGA),Phaseolus vulgarisagglutinin (PHA) andLens culinarisagglutinin (LCA), on the function of human platelets. We have found that WGA is more active than PHA in stimulating platelet activation/aggregation, while LCA has no effect. Studies on the mechanisms involved show that WGA and PHA induce phosphorylation/activation of PLCγ2 and increase [Ca2+]i. For the first time, it has been shown that Src/Syk pathway, the adapter protein SLP-76 and the exchange protein VAV, participate in the PLCγ2 activation by these lectins. Moreover WGA and PHA stimulate the PI3K/AKT pathway. PI3K, through its product phosphatidylinositol-3,4,5-trisphosphate activates Bruton’s tyrosine kinase (BTK) and contributes to PLCγ2 activation. In conclusion, our findings suggest that PLCγ2 activation induced by WGA and PHA is regulated by Src/Syk and by PI3K/BTK pathways through their concerted action.

Abstract

Background
The Build, Educate, Advance, Transition, in Sickle cell disease (BEATS) music therapy program was developed to address health challenges faced by adolescents/young adults (AYA) with sickle cell disease (SCD) during the transition to adult medical care.

Objective
The purpose of this study was to investigate the effects of BEATS on self-efficacy, trust, knowledge about SCD, and adherence in adolescents/young adults (AYA) with SCD.

Subjects
Thirty AYA with SCD, 18–23 years old, recruited from an adult SCD clinic agreed to participate in four BEATS sessions over 1 year.

Methods
Self-efficacy, trust and SCD knowledge were measured prospectively at baseline and months 3, 6, 9, and 12. Adherence to clinic appointments and healthcare utilization were measured retrospectively from medical records. A repeated measures linear mixed-effect model with compound symmetry covariance structure was used to fit the data.

Results
BEATS participants demonstrated a significant improvement in SCD knowledge (p = 0.0002) compared to baseline, an increase in acute care clinic, but not emergency department, utilization (p = 0.0056), and a non-significant improvement in clinic attendance (p = 0.1933). Participants’ subjective evaluations revealed a positive response to BEATS. There were no significant changes in self-efficacy, trust, hospital admissions, or blood transfusion adherence.

Conclusion
Culturally tailored, developmentally appropriate music therapy transition interventions can concretely improve SCD knowledge and may improve transition for AYA with SCD.

Abstract

Background
Physical Education and Sport (PES) is compulsory in Cameroonian education system. Cardiac accidents and sudden cardiac deaths (SCD) have been reported during PES examinations. This study aimed to contribute in the prevention of these cardiac accidents by studying pre- and post-exercise electrocardiogram (ECG) pattern modifications in apparently healthy school adolescents.

Methods
One hundred school adolescents without apparent heart disease [aged 18 ± 2 years; body mass index (BMI): 21.9 ± 2.3] were included. Participants performed two intermittent sprint-endurance tests. The test consisted in walking 2000 m as warm-up, followed by sprint and endurance races. A 12-leads ECG was performed before and in 5 min after the tests. ECG patterns changes were studied with particular attention to abnormalities that could be associated with risk of SCD.

Results
At rest, ECG patterns variants consisted of bradycardia (30%), sinus arrhythmia (9%), posterior hemi post-block (2%), and early repolarization (3%). which disappeared after exercise in all participants. QTc (ms) and heart rate (HR) increased after exercise (p < 0.001); and RR (ms) decreased post-exercise (p < 0.001). Other changes includes the appearance of the T-waves reversed in precordial leads (V2–V4) (p < 0.001), ventricular (6%), atrial and other supraventricular premature beats (2%) in the post-exercise ECG. Left ventricular hypertrophy (2%), right auricular enlargement (2%), short PR (2%) appeared at the end of the tests.

Conclusion
This study suggests that an intermittent exercise can induce cardiac abnormalities able to provoke cardiac accidents and SCD in apparently healthy school adolescents.
Preparation and TG/DTG, FT-IR, SEM, BET Surface Area, Iodine Number and Methylene Blue Number Analysis of Activated Carbon from Pistachio Shells by Chemical Activation
Authors: Kaya Mustafa , Şahin Ömer , Saka Cafer 
Published: August 2017

AbstractIn this study, low cost activated carbon was prepared from the pistachio shell by chemical activation with zinc chloride (ZnCl2). The prepared activated carbon was characterized by thermogravimetry (TG) and differential thermal gravimetry (DTG), infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and Brunauer, Emmett and Teller (BET) surface area analyses. Results showed that the activation temperature and impregnation ratio have significant effect on the iodine number of the prepared activated carbon. The optimum conditions for preparing the activated carbon having the highest surface area were found to be an activation temperature of 700 °C, soaking time of 24 h and ZnCl2/ pistachio shell ratio of 50 %. The results showed that the BET surface area, total pore volume, iodine number and methylene blue (MB) number of activated carbon prepared under the optimum conditions were 1108 m2/g, 0.39 cm3/g, 1051 mg/g, 98.48 mg/g, respectively.

Abstract
In this paper, a Haar wavelets based numerical method to solve a system of linear or nonlinear fractional differential equations has been proposed. Numerous nontrivial test examples along with practical problems from fluid dynamics and chemical engineering have been considered to illustrate applicability of the proposed method. We have derived a theoretical error bound which plays a crucial role whenever the exact solution of the system is not known and also it guarantees the convergence of approximate solution to exact solution.
Optimization and In-vitro Evaluation of Coating Process for Film-Coated Tablets
Authors: Maki Marwan Abdelmahmoud Abdelkarim , kumar Palanirajan Vijayaraj , Wei Yeong Siew 
Published: August 2017

Abstract
The proper efficiency of the tablet-coating process often results in a coating within adequate quality, which might avoid the rejection of the film-coated tablets, minimize the operating expenses and production time. In general, the optimum coating system performance and coating conditions are important for achieving the desirable tablet-coating uniformity and manufacturing reproducibility. In this study, HPMC-aqueous-based tablet film coating successfully conducted in a perforated pan coater for process scale-up using the spray-coating technique. Certain process parameters such as spray rate, inlet air temperature, pan temperature, atomizing pressure as well as pan speed were maintained carefully and the optimum coating quality was achieved with acceptable film performance. At lower initial pan speed, the strength of the coated tablets was remarkably improved and the highest weight gain obtained. The smoothest and uniform film obtained at high spray rate, high pan speed, and low atomizing pressure. The results revealed that the optimum film-coating quality and uniformity achieved at a spray rate of 480 ml/min, atomizing pressure at 5 bar, inlet temperature at 85 to 90 °C, pan temperature at 58 °C, initial pan speed at 1.5 rpm and final pan speed at 4.0 rpm using side-vented pan coater. At initial pan speed of 1.5 rpm, the strength of the coated tablets remarkably improved with minimum edges erosion, which increases the weight gain up to 3.3%w/w.
Gravity Meets Pricing to Market: What a Combined-Method Approach Tells Us on German Beer Exports and Pricing
Authors: Dreyer Heiko , Fedoseeva Svetlana , Herrmann Roland 
Published: August 2017

AbstractGravity and pricing to market (PTM) models have been used to elaborate determinants of bilateral trade and export pricing for different countries and branches. Typically, only one of the two methods was chosen. We show in a stepwise approach how a combination of both methods can reveal novel results on the determinants of exports and export pricing behaviour. For the case of German beer exports, we show that structural differences exist between markets on which exporters apply either PTM or non-PTM strategies. German beer exporters apply PTM strategies, in particular local-currency stabilization, on those markets where imports are very sensitive to exchange-rate changes. Non-PTM strategies, i. e. full exchange-rate transmission, occur on export markets with insensitive reactions. Apart from PTM strategies, German beer exports are strongly dependent on policy variables such as the introduction of the Euro and the partner country’s membership in the EU.
