Published: December 2017

ABSTRACTThe introduction and utilization of new maize (Zea mays L.) germplasm from sources, such as the International Maize and Wheat Improvement Center (CIMMYT), can be valuable for broadening the genetic base of breeding populations through the introgression of new alleles. Twenty‐five inbred lines, derived from CIMMYT breeding populations, were selected on the basis of grain color, resistance to turcicum leaf blight, and per se line performance in Yunnan. To use the lines effectively, information on their performance in hybrid combinations and on general combining ability (GCA) and specific combining ability (SCA) needed to be obtained. The objectives of this study were (i) to evaluate these lines for grain yield (GY) in hybrid combinations and determine GCA of parental lines and SCA of crosses between the 25 introduced lines and six testers using North Carolina Design II; and (ii) to classify the lines into different maize heterotic groups. The field testing at three locations identified crosses with lines from Cateto and Population 147 (P147) as having significantly higher GY than those from SA3 and other introduced populations, and the high GY was largely attributable to their high positive GCA effects. Lines from the same population were not necessarily classified into same maize heterotic group. Lines selected at S4 or a later generation would be expected to have more stable GCA effects than lines selected in earlier generations.

Core Ideas
Terrestrial lidar technology can provide surface data at high spatial resolution and accuracy.
For rill erosion within furrows, lidar provides high‐quality quantitative information.
Sheet erosion is more difficult to quantify.
Soil swelling needs to be taken into account.
Terrestrial lidar technology provides accurate surface data at high spatial resolution. This study examined the ability of lidar scanners to evaluate soil erosion and deposition at high spatial and temporal resolutions. Lidar scans were conducted in six field plots with three different tillage systems during two rain seasons, focusing on four major rainfall events. Results show that the lidar scanner identifies changes in the surface elevation in the case of rill erosion within the furrows. In these cases, the high‐quality quantitative data can assist practical decision‐making and can contribute to the calibration of physically based erosion models. In other cases, however, the results show that the ability of the lidar scanners to detect erosion and deposition processes is limited. The reasons for this limitation are the minor effect of sheet erosion on flat surfaces and soil swelling and shrinking occurring during and after rainfall events. Swelling–shrinking and soil compaction processes need to be taken into account during lidar scanning, as their magnitude is comparable to that of soil loss by erosion. On the other hand, the ability to measure these processes allows investigation of the dynamics of surface processes during wetting and drying sequences. The results showed also that the effect of the rainfall pattern was stronger when the rainfall intensity and the initial soil moisture were higher, and that rill erosion is more important when the furrows are parallel to the slope direction, while deposition is accentuated when the furrows are perpendicular to the slope.
Diagnosis of acute compartment syndrome following regional anaesthesia

Published: December 2017

SummaryA 54‐year‐old female required open reduction and internal fixation of a left sided distal radius and ulnar fracture. Due to suffering from a concurrent chest infection and significant chronic obstructive pulmonary disease, she underwent the procedure using regional anaesthesia. The operation was completed without incident using an axillary brachial plexus nerve block. Following this, the patient developed severe forearm pain in the post‐anaesthetic recovery unit despite otherwise dense sensorimotor block in her arm. A diagnosis of iatrogenic compartment syndrome was made secondary to plaster cast immobilisation. The symptoms were alleviated by releasing the cast. The patient subse quentlymade an uncomplicated recovery. This case highlights how it is possible to diagnose acute compartment syndrome in the presence of working regional anaesthesia.
Evaluating the suitability of tungsten, titanium and stainless steel wires as current collectors in microbial fuel cells
Authors: Sharma I. , Ghangrekar M. M. 
Published: December 2017

AbstractAn appropriate current collector (CC) is crucial for harvesting substantial power in a microbial fuel cell (MFC). In the present study, stainless steel (SS) and titanium wires were used as the CCs for both the anode and cathode of MFC-1 and MFC-2, respectively. Tungsten wire (TW) was used as the anode CC in MFC-3, with SS wire as the cathode CC. In MFC-4, TW was used as the cathode CC with SS wire as the anode CC, and in MFC-5 both electrode CCs were TW. The power density, current density, oxidation current and bio-capacitance were compared to select the best and most cost effective CC material to enhance the power output of MFCs. Maximum power densities (mW/m2) of 32.28, 93.10, 225.38, 210.74, and 234.88 were obtained in MFC-1, MFC-2, MFC-3, MFC-4, and MFC-5, respectively. The highest current density (639.86 mA/m2) and coulombic efficiency (23.12 ± 1.5%) achieved in MFC-5 showed TW to be the best CC for both electrodes. The maximum oxidation current of 7.4 mA and 7 mA and bio-capacitance of 10.3 mF/cm2 and 9.7 mF/cm2 were achieved in MFC-3 and MFC-5, respectively, suggesting TW is the best as the anode CC and SS wire as the cathode CC to reduce MFC fabrication costs.

Background:
Crocus sativus (Iridaceae) has been traditionally used in the Iranian folk medicine and
as a culinary additive. Major components of the plant that are responsible for biological properties are saffranal,
crocin, picrocrocin and crocetin. Although the level of crocetin is not high, some of the important activities of
saffron such as antioxidant activity have been attributed to crocetin.

Objective:
In the present study, we investigated the effects of crocetin on melanogenesis in B16 melanoma cells.

Methods:
The effect of crocetin on intracellular and mushroom tyrosinase activity and the content of melanin
was evaluated spectrophotometrically. Tyrosinase and Microphthalmia-Associated Transcription Factor (MITF)
protein levels were compared between Crocetin-treated and control cells after western blot analysis. The antioxidative
activity of crocetin was also investigated.

Results:
Crocetin could inhibit mushroom tyrosinase activity and lower the amount of melanin in B16
melanoma cells. Protein levels of tyrosinase and MITF were also decreased by crocetin. Crocetin also showed
antioxidant activity and depleted cellular Reactive Oxygen Species (ROS) content but had no cytotoxicity in
alamarBlue® assay.

Conclusion:
Taken together, decreased tyrosinase activity, melanin content, tyrosinase and MITF proteins levels,
and ROS production showed the inhibition of melanogenesis in B16F10 cells by crocetin. Hence, crocetin
could be suggested as a potential dermatological whitening agent in skin care products.

Published: December 2017

BACKGROUND

Although electronic medication administration record systems have been implemented in settings where nurses work, nursing students commonly lack robust learning opportunities to practice the skills and workflow of digitalized medication administration during their formative education. As a result, nursing students’ performance in administering medication facilitated by technology is often poor. Serious gaming has been recommended as a possible intervention to improve nursing students’ performance with electronic medication administration in nursing education.

OBJECTIVE

The objectives of this study are to examine whether the use of a gamified electronic medication administration simulator (1) improves nursing students’ attention to medication administration safety within simulated practice, (2) increases student self-efficacy and knowledge of the medication administration process, and (3) improves motivational and cognitive processing attributes related to student learning in a technology-enabled environment.

METHODS

This study comprised the development of a gamified electronic medication administration record simulator and its evaluation in 2 phases. Phase 1 consists of a prospective, pragmatic randomized controlled trial with second-year baccalaureate nursing students at a Canadian university. Phase 2 consists of qualitative focus group interviews with a cross-section of nursing student participants.

RESULTS

The gamified medication administration simulator has been developed, and data collection is currently under way.

CONCLUSIONS

If the gamified electronic medication administration simulator is found to be effective, it could be used to support other health professional simulated education and scaled more widely in nursing education programs.

Persiles
Authors: Albistur Jorge 
Published: December 2017

Obra póstuma, Los trabajos de Persiles y Sigismunda ha sido tenida, ateniéndose a la posible fecha de composición y casi inexplicablemente, como la primera y la última obra de Cervantes. Una buena lectura exige despejar el asunto de su ubicación cronológica, pues hacerlo ayuda a situar correctamente al Persiles en el conjunto de la producción cervantina. Los siglos han interpretado la novela de modos bien distintos, como igualmente la Ilustración, el romanticismo y el 98 leyeron un Quijote diferente. En la conmemoración del cuarto centenario de la muerte de Cervantes, es bueno revisar las lecturas del pasado. Es tarea necesaria, asimismo, explorar en las etimologías, los símbolos y los episodios alegóricos que pueden iluminar un mensaje de la novela. En nuestra opinión, ese mensaje es confirmatorio del Cervantes librepensador y erasmista, adelantado a su tiempo, que se ha visto a partir del Quijote. Unas páginas del Persiles asoman a otra cuestión, singularmente importante cuando se lee en estos litorales: la presencia de América en la obra de Cervantes. De tal modo pasea su mirada curiosa por todas las fronteras del universo conocido.

Presentamos los principales resultados del análisis de los discursos que profesorado y alumnado (según sexo) han elaborado sobre los fies de un conjunto de asignaturas de titulaciones universitarias de la Universitat Autònoma de Barcelona (UAB) (Catalunya, España). Analizamos, desde la perspectiva de género, qué tipo de relaciones de cuidado y de provisión remiten dichos discursos. Identifiamos una concepción compartida entre profesorado y alumnado, independientemente del sexo y de la titulación, que pone el acento en la provisión como principal fi de las asignaturas. La incorporación de la dimensión del cuidado en los fies aparece como un elemento secundario.

Penyakit demam berdarah dengue merupakan penyakit yang berbahaya karena dapat menye-babkan kematian dalam waktu relatif singkat. Penyakit ini disebabkan oleh virus dengue yang masuk ke dalam tubuh manusia melalui gigitan nyamuk Aedes sp. Kegiatan pencegahan pe-nyakit DBD yang dilakukan di antaranya adalah dengan menabur bubuk larvasida pada tempat penampungan air yang sulit dibersihkan. Larvasida yang sering digunakan oleh masyarakat abate (temephos 1 %). Tujuan penelitian adalah untuk mengetahui efektivitas aplikasi larvasida temephos 1 % menggunakan sistem membran dengan kain paris yang dibandingkan dengan sistem tabur. Jenis penelitian yang digunakan adalah eksperimen dengan rancangan post-test with control group. Sampel larva Aedes sp adalah instar III dan IV atau berumur 4-6 hari se-telah penetasan telur sebanyak 1350 ekor secara keseluruhan. Perhitungan kematian larva di-lakukan setelah 24 jam kontak dengan temephos 1 % yang dilakukan setiap dua minggu sekali selama tiga bulan. Data yang diperoleh dianalisis menggunakan uji t-test bebas dengan derajat kepercayaan 95 %. Hasil memperlihatkan bahwa rerata persentase kematian larva Aedes sp akibat aplikasi larvasida temephos 1 % dengan sistem membran, pada pengamatan dua ming-gu pertama sampai ke enam, secara berturut-turut adalah: 100 %, 94 %, 80 %, 68 %, 35 %, dan 23 %; sedangkan pada aplikasi sistem tabur sebagai kontrol positif adalah 100 %, 86 %, 37 %, 23 %, 12 %, dan 6 %. Secara deskriptif berdasarkan grafik perbedaan kematian larva dapat disimpulkan bahwa aplikasi sistem membran lebih efektif dibandingkan dengan sistem tabur. Namun demikian, analisis statistik terhadap data kematian pada pengamatan dua ming-gu yang pertama hingga ke-enam, menunjukkan bahwa perbedaan persentase rata-rata kema-tian larva Aedes sp dari kedua jenis aplikasi tersebut tidaklah bermakna (nilai p = 0,298).

Published: December 2017

Bakteri Coliform merupakan indikator terjadinya pencemaran tinja dalam air. Banyaknya Coli-form di dalam air dapat menyebabkan penyakit pada manusia yang mengkonsumsi air terse-but. Salah satu upaya untuk menurunkannnya adalah melalui disinfeksi. Tujuan penelitian ini adalah untuk mengetahui efektivitas penggunaan disinfektan alami berupa campuran serbuk kulit nanas dan arang aktif dalam menurunkan MPN Coliform pada air bersih. Penelitian ini me-rupakan pre-xperiment dengan menggunakan rancangan one group pre-test post-test. Ada tiga variasi disinfektan yang digunakan (yaitu perbandingan 1:1, 1:2 dan 1:3) dan dua waktu pe-maparan, masing-masing diaplikasikan ke dalam 5 liter air yang mengandung bakteri Coliform, dalam tiga kali ulangan. Pemeriksaan MPN Coliform dilakukan di Laboratorium Mikrobiologi Ju-rusan Kesehatan Lingkungan Poltekkes Kemenkes Yogyakarta. Hasil analisis statistik menggu-nakan t-test terikat pada α 0,05 menghasilkan nilai p sebesar 0,003 yang menunjukkan bahwa MPN Coliform pre-test dan post-test berbeda secara bermakna. Hasil analisis berikutnya de-ngan menggunakan one way anova pada α yang sama, untuk pemaparan 30 menit diperoleh nilai p value 0,249, dan untuk pemaparan 60 menit diperoleh nilai p value 0,724; yang berarti bahwa MPN Coliform hasil post-test di antara tiga variasi dosis disinfektan yang digunakan pada kedua waktu pemaparan, tidak berbeda secara bermakna. Berdasarkan hasil tersebut dapat disimpulkan bahwa campuran serbuk kulit nanas dan arang aktif sebagai disinfektan ala-mi berpengaruh dalam menurunkan MPN Coliform. Namun demikian, perbedaan penurunan yang terjadi di antara ketiga dosis dan waktu pemaparan yang diteliti tidaklah signifikan.
