Authors: Snijders T.E. , Schlösser T.P.C. , van Gaalen S.M. , Castelein R.M. , Weinans H. , de Gast A. 
Published: July 2018

Background:
Acetabular cup orientation plays a key role in implant stability and the success of total hip arthroplasty. To date, the orientation has been measured with different imaging modalities and definitions, leading to lack of consensus on optimal cup placement. A 3-dimensional (3D) concept involving a trigonometric description enables unambiguous definitions. Our objective was to test the validity and reliability of a 3D trigonometric description of cup orientation.

Methods:
Computed tomographic scans of the pelvis, performed for vascular assessment of 20 patients with 22 primary total hip replacements in situ, were systematically collected. On multiplanar reconstructions, 3 observers independently measured cup orientation retrospectively in terms of coronal inclination, sagittal tilt, and transverse version. The angles measured in 2 planes were used to calculate the angle in the third plane via a trigonometric algorithm. For correlation and reliability analyses, intraobserver and interobserver differences between measured and calculated angles were evaluated with use of the intraclass correlation coefficient (ICC).

Results:
Measured and calculated angles had ICCs of 0.953 for coronal inclination, 0.985 for sagittal tilt, and 0.982 for transverse version. Intraobserver and interobserver reliability had ICCs of 0.987 and 0.987, respectively, for coronal inclination; 0.979 and 0.981, respectively, for sagittal tilt; and 0.992 and 0.978, respectively, for transverse version.

Conclusions:
The 3D concept with its trigonometric algorithm is a valid and reliable tool for the measurement of cup orientation.

Clinical Relevance:
By calculating the transverse version of cups from coronal inclination and sagittal tilt measurements, the trigonometric algorithm enables a 3D definition of cup orientation, regardless of the imaging modality used. In addition, it introduces sagittal tilt that, like pelvic tilt, rotates around the transverse axis.

Acceptability of fall prevention strategies for older people with vision impairment
Authors: Dillon Lisa , Duffy Patricia , Tiedemann Anne , Keay Lisa 
Published: July 2018

Abstract
Despite the high risk of falls for older people with vision impairment, adherence to exercise-based fall prevention programs is low. We investigated the attitudes of older people with vision impairment to fall prevention programs as well as home modifications. This was completed through focus group and semi-structured interviews with 19 community-dwelling people aged ≥63 years with vision impairment. The results indicated that participants did not attribute falls to vision impairment, nor consider themselves appropriate candidates for a fall prevention program. Participants also reported such barriers as competing priorities, transport issues and comorbidities. It is recommended that exercise-based fall prevention programs cater to the unique challenges of this population, such as delivery in home by Orientation and Mobility Specialists.
Chemotaxis of Caenorhabditis elegans toward volatile organic compounds from Stropharia rugosoannulata induced by amino acids
Authors: Bian Jing , Zhang Haili , Meng Shuai , Liu Yajun 
Published: July 2018

Abstract
A variety of natural substances including both volatile organic compounds and water-soluble compounds play a significant role in the chemotactic behaviors of the model nematode Caenorhabditis elegans. We observed chemotactic behaviors of C. elegans with respect to response to attractants produced by nematode parasitic fungus Stropharia rugosoannulata, which were partially induced by specific amino acids. The results of gas chromatography-mass spectrometer analysis suggested that 1-octen-3-ol was produced and benzaldehyde concentrations increased when L-phenylalanine was added to water agar plate. Similarly, the addition of L-tryptophan to the medium induced the production of benzaldehyde, 1-octen-3-ol and indole. The presence of L-phenylalanine and L-tryptophan increased the attraction of C. elegans to S. rugosoannulata. With attraction increased, nematode mortality increased more than 6 times higher.

Published: July 2018

Abstract
Tifguard was released in 2008 as a peanut cultivar with a high level of resistance to Meloidogyne arenaria. Our objective was to determine the role of temperature on infection and development of M. arenaria in Tifguard compared to that in the nematode susceptible cultivar, Georgia-06G. Temperature affected the rate of nematode infection and development in both Tifguard and Georgia-06G (P ≤ 0.05). In Georgia-06G, egg-laying females were observed 25, 20 or 25 days after inoculation at 28°C, 31°C, and 34°C, respectively. There were greater numbers of nematodes entering roots and acceleration of development in response to 31°C compared with that at 28°C. There was, however, a decrease in the number of nematodes entering roots and their development was retarded at 34°C compared with that occurring at 31°C. Although second-stage juveniles penetrated Tifguard roots, they did not develop further at 28°C or 31°C; however, at 34°C both females, males, and a few egg-laying females of M. arenaria were observed. The optimum temperature for nematode infection and development was 31°C in Georgia-06G. In summary, it is unlikely that high soil temperatures would lessen the effectiveness of the nematode resistance gene in Tifguard.

Abstract
Soybean cyst nematode (SCN, Heterodera glycines Ichinohe) is a serious soybean pathogen worldwide. HG Type 0 had been a predominant SCN in Heilongjiang province, the largest soybean (Glycine max L.) producing region in China. Recently, increased virulence on resistant cultivars originally developed for resistance to HG Type 0 was observed in fields. In order to identify new cultivars resistant to local SCN populations, two soil samples were collected from two counties (Anda and Wuchang) in which increased virulence on resistant cultivars occurred, and single-cyst cultures from each soil sample were maintained for more than five generations. Two single-cyst cultures from the Anda sample were identified as HG Type 1.2.3.5.6.7 and HG Type 1.3, and one single-cyst culture from Wuchang was identified as HG Type 2.5.7. Then 18 soybean genotypes, including 11 local cultivars originally developed for resistance to HG Type 0, were used to evaluate resistance response to the three identified SCN populations. Various levels of resistance or susceptibility to the three SCN populations were observed among 18 genotypes. Two tests produced similar results for the three SCN populations. Both ‘Kangxian12’ and ‘Kangxian13’ showed resistance or moderate resistance to HG Type 2.5.7, HG Type 1.2.3.5.6.7 and HG Type 1.3. The germplasm ‘09-138’ was resistant to HG Type 1.3 and HG Type 1.2.3.5.6.7. Cultivars with ‘Peking’-resistance were resistant or moderately resistant to HG Type 2.5.7 in both tests except for ‘Kangxian8’ in test 1. The identified resistant varieties would be valuable sources of breeding materials for resistance against multiple SCN populations.
The Structure of Node and Edge Generation in a Delusional Social Network
Authors: Martin John Levi 
Published: July 2018

Abstract
A rare set of data on a changing social network of personalities, drawn by a sufferer of Multiple Personality Disorder are investigated using random graph theory. The key features guiding the patient’s production of these wholly delusional networks, features which define her “schema” of social network, are derived by fitting a family of nested distributions. From this, we can derive a tentative hypothesis of how the laity may understand the logic of social networks, a hypothesis that is consonant with other forms of informal evidence.

Abstract
The aim of this study was to evaluate the usefulness of chromogenic media for isolation of bacteria from urine and direct identification of UTI pathogens. A total of 100 urine specimens were inoculated on blood agar and MacConkey agar as a reference method and on the following media to be tested: chromID® CPS® Elite (CPSE, bioMérieux), CHROMagarTM Orientation (BioMaxima), BD CHROMagar Orientation Medium (ORI, Becton Dickinson), CHROMagarTM Orientation (ORIE, Graso) and Brillance UTI Clarity Agar (UTI C, Oxoid). After a 24-hour incubation period, 47 Gram-positive cocci and 62 Gram-negative rods were observed. The specificity and sensitivity of all chromogenic media was 97.3% and 93.5% respectively for qualitative diagnostic; and 81.9% and 81.3% respectively for semi-quantitative diagnostic. The mean PPV and NPV of the chromogenic media were 98.7% and 87.7% for qualitative UTI diagnostic, and 90.9% and 71.9% respectively for semi-quantitative diagnostic.

Published: July 2018

The paper presents the studies on the degree of raw fat extraction from meat systems by various methods. Relative differences in extraction methods are shown depending on the polarity of solvents used. Fat was extracted using the classical Soxhlet method, as well as two-step extraction. Specially prepared model systems were used as test samples including both simple and multicomponent mixtures in the form of meat-and-bone meal, bone meal, and meat-and-plant meal. It was found that when using non-polar solvents, a large amount of polar lipids was lost. The influence of the solvent on the degree of extraction for glycerides, phosphatides, free fatty acids and oxidation products was shown. A number of experiments are presented and the results are given on the degree of fat extraction using mixtures of organic solvents with mineral acid. The studies allowed to choose the best extraction method for each type of meat and meat-containing raw materials. Based on the results, methodical recommendations are proposed on the use of hydrophobic and hydrophilic solvents and their mixtures. Methods of lipid extraction from food products after alkaline and acid hydrolysis are considered. Examples of fat determination by instrumental methods (refractometry) are given. Classical methods for fat content evaluation are described (Randall method, Twisselmann method, and Rushkovsky method).ContributionAll authors bear responsibility for the work and presented data.

Providing the country’s population with quality food products in a demanded range and quantity is an important national economic task. A priori in the implementation of appropriate social and economic programs, an important place is taken by products of the dairy industry. Taking into account the geographical features and climatic conditions of Russia, strategic considerations, the existing fragmentation of the consumer market and economic factors, special importance is acquired by researches, aimed at improving traditional and developing new technologies for canned milk products, as high-nutritional products with a pronounced priority of enhanced storage stability. The system of ensuring the stabilization of canned milk in storage is represented by two main blocks: technologically formed potential and post-technological requirements for its maintenance. The first forms the basic properties of the product and stabilizes them. The second one is to ensure the conditions under which the risks of initiation and/or intensity of the abiogenic and biogenic nature degradation reactions are minimized. To assess the canned milk quality and safety proposed and standardized a number of relevant indicators. However, taking into account the technology development, the expansion of the raw ingredients range, the requirements for the extension of shelf life and much more, the scope of the evaluation criteria for quality and safety indicators is constantly expanding, new methods of a priori and a posteriori analysis are being created, which is fixed in normative and technical documents, that are integrally reflected the level of modern technology. An analysis of the world tendencies in the development of canning, shows, that the reserves of improving the traditional technologies of dairy canned food, increasing their quality, are far from exhausted. Significant potential lies in the research of thermodynamic characteristics, functional and technological indicators of dairy products and further implementation of the obtained data, as system criteria of the technological operations rationality definition, the validity of production schemes, and the evaluation of product quality. The data, obtained over the last decades on the indicator of «water activity», inhibition of the degradation of micro and macro components, «barrier» conservation technologies and many other directions in various food systems can suggest, that it is possible to mediate most of the methodological approaches applied to canned milk technologies, to predict strategic, economic and social significance of such developments.

Increased public health risk caused by pathogen contamination in streams is a serious issue, and mitigating the risk requires improvement in existing microbial monitoring of streams. To improve understanding of microbial contamination in streams, we monitored Escherichia coli in stream water columns and streambed sediment. Two distinct streams and their subwatersheds were studied: (i) a mountain stream (Merced River, California), which represents pristine and wild conditions, and (ii) an agricultural stream (Squaw Creek, Iowa), which represents an agricultural setting (i.e., crop, manure application, cattle access). Stream water column and sediment samples were collected in multiple locations in the Merced River and Squaw Creek watersheds. Compared with the mountain stream, water column E. coli concentrations in the agricultural stream were considerably higher. In both mountain and agricultural streams, E. coli concentrations in bed sediment were higher than the water column, and principal component analysis indicates that land use affected water column E. coli levels significantly (p < 0.05). The cluster analysis showed grouping of subwatersheds for each basin, indicating unique land use features of each watershed. In general, water column E. coli levels in the mountain stream were lower than the USEPA's existing water quality criteria for bacteria. However, the E. coli levels in the agricultural stream exceeded the USEPA's microbial water quality criteria by several fold, which substantiated that increased agricultural activities, use of animal waste as fertilizers, and combined effect of rainfall and temperature may act as potential determining factors behind the elevated E. coli levels in agriculture streams.Core Ideas
Watershed land use influences in‐stream pathogen contamination and hence public health risk.
The agricultural stream showed higher E. coli concentration than the mountain stream.
Increased forest and grassland use showed lower E. coli concentrations in stream water.
Increased agricultural land use showed higher E. coli concentrations in stream water.
The agricultural stream water column E. coli concentrations far exceeded USEPA recommended values.
