Authors: Červenka Libor , Fruhbauerová Michaela , Velichová Helena 
Published: March 2019

Carob (Cerationa soliqua L.) pod is the good source of dietary fiber, minerals and polyphenolic substances. The aim of this study was to prepare muffin where wheat flour was substituted with carob powder, and determine some physicochemical properties. Carob powder was prepared by milling dry carob pods to particles smaller than 600 μm. Then wheat flour in muffin dough was replaced by carob powder in 5, 10, 15 and 20% (w/w) and subsequently baked at 180 °C for 20 min. It was found that the height of the muffin fortified with carob powder decreased in comparison with that in control muffin sample. Although the height of muffins decreased with the increase in level of carob powder, the differences were not statistically significant. Weight loss was similar for all the muffin samples in this study. Moisture content of muffins with carob powder was significantly higher than that in control. Addition of carob powder had also effect on water activity of muffin. While 0.905 aw was observed in control sample, significantly higher aw values were determinated in fortified muffins (0.912 – 0.923 aw). The antioxidant characteristics were determinated using spectrophotometric assays for total phenolics (TPC), total flavonoids (TFC), radical scavenging activities (DPPH, ABTS) and hydrogen peroxide scavenging (HPS). TPC values gradually increased with the increase in level of carob powder from 348.1 to 829.1 μg gallic acid.g-1 dry matter but TFC values significantly increased in muffin with 15 and 20% (w/w) of carob powder. All the antioxidant assays showed strong and positive association with the increase in level of carob powder. Addition of carob powder resulted in the increase of browning index and FAST index as a metrics of the formation of Maillard products.

Repensar los valores de la sociedad humana para reconocer la «Tierra Patria» que propone Edgard Morín, que en el lenguaje de las Naciones Unidas se denomina desarrollo sostenible, marca una tendencia hacia las políticas de educación superior, el comportamiento de la generación de conocimiento e información a través de publicaciones y las declaraciones de políticas de las universidades públicas es de utilidad para identificar las acciones nacionales hacia esta tendencia. En esta investigación se identificó el interés en publicaciones de artículos indexados y publicaciones institucionales en el tema. En Honduras los documentos de modelos educativos incluyen, a nivel de macroestructura y mesoestructura, elementos que muestran intentos de integrar dimensiones del desarrollo sostenible como la dimensión social y ambiental. Los esfuerzos nacionales están siendo completados con apoyo de movimientos en la región centroamericana, como es el caso de la transversalización del currículo con los temas cambio climático y gestión de riesgo.

Depository Designations
Authors: Ahrens Aric 
Published: March 2019

Though the FDLP Modernization Act of 2018 failed to land on the president’s desk, the first serious attempt at a legislative solution to the structural hindrances facing the Federal Depository Library Program (FDLP) must be applauded. In particular, granting the Superintendent of Documents the authority to designate depositories is a vast improvement over the current and ancient Congressional District Model of Depository Allocation. The inadequacies of this well intentioned method of allocating depositories nationwide have been articulated since the nineteenth century.
Possibility of Allelopathic and Residues Effects of the Rotated Crops on Productivity, Chemical Composition, Nitrogen Utilization of Wheat (Triticum aestivum) and Soil Fertility
Authors: El-Shamy Moshira A. , El-Naqma Kholoud A. 
Published: March 2019

Aims: To evaluate the possibility of allelopathic effects of the rotated crops on productivity, chemical composition, N utilization of wheat and soil fertility.
Study Design: A split plot design with three replications was used. The main plots were assigned with three previous crops, The sub plots were assigned by three nitrogen fertilizer rates (0, 35 and 70 kg N fed-1).
Place and Duration of Study: A field study was carried out at Sakha Agricultural Research Station farm, ARC, Kafr El-Sheikh governorate, Egypt, during two successive seasons of 2016/2017and 2017/2018
Methodology: The local wheat cultivar (Sids 12) was sown after three crops (fahl berseem) after rice, (Drawa) after rice and Fallow after rice as preceded crops.
Results: The results showed that fahl berseem roots and residues in the clover (berseem)-wheat rotation secreted biologically active chemical compounds which have a positive effect on growth and development of wheat. The preceding clover (fahl berseem) wheat rotation appeared to be promising for wheat productivity, N, P, K concentrations, N-uptake, N utilization, protein content of wheat grain and straw, availability of N, P and K after wheat harvest compared with fallow after rice, green maize (drawa-wheat rotation). The interaction between the preceded crops and N fertilizer rates was significantly for all the studied traits. The highest performance of wheat traits were observed when wheat was grown after fahl berseem and fertilized with 70 kg N.fed-1. While the lowest performance was obtained following cereal crops rice (fallow) and the lowest N level in both seasons. Treatment of fahl berseem with nitrogen fertilizer (70 kg N.fed-1) had given a best values from grain yield with relative increments of (37.54%) compared with preceding rice-wheat rotation and (23.26%) compared with rice-drawa rotation.
Conclusions: Cereal winter crops can be sow after preceding legume crops rather than summer cereal crops. We can sow fahl berseem crop as a forage to animals after cereal crop (rice) and before sowing wheat crop to improve soil properties and its availability of the essential elements and consider additional revenue to farmer. Fahl barseem had be sown in the end of august month after rice crop to produce approximetly 20 ton fresh forage.fed-1 (~ 9 ton dry grass.fed-1) which provides farmers with (~ 9 thousands EL) in 88 days only.
A Survey of Symptoms of Fungal Disease in Sugarcane (Saccharum officinarum L.) in Buea, in the South West Region of Cameroon
Authors: Tambe Bechem Eneke Esoeyang , Jackai Mbella Clara Elinge 
Published: March 2019

Aim: Sugarcane (Saccharum officinarum L.) which is mostly cultivated in tropical and subtropical regions of the world is an important source of sucrose. This crop which was originally grown in South Eastern Asia and the Pacific for the sole purpose of chewing is mainly used nowadays for the production of sugar, bio-fuels, medicine etc. In spite of its numerous uses, the production of sugarcane in Buea, South West region of Cameroon is hampered by many factors including the incidence of disease. It is possible that some varieties are no longer cultivated because of their susceptibility to fungal diseases. It was for these reasons that we decided to survey the sugarcane farms in this area, to evaluate the presence of diseased symptoms due to activity of fungi.
Study Design: Random sampling.
Place and Duration of Study: Buea and its environs, Rubber Pathology Laboratory IRAD Ekona, and Life Sciences Laboratory, University of Buea, between June 2016 and July 2017.
Methodology: During the survey, sugarcane farms in five villages in Buea and its environments were visited. The leaves and stems of the plants were observed for any symptoms of fungal activity. The incidence, severity and prevalence of the symptoms were noted. Leaf samples were collected from diseased sugarcane plants and transported to the laboratory for the isolation of fungi on Potato Dextrose Agar growth medium. The isolates were identified based on their cultural and micro-morphological characteristics.
Results: Sugarcane plants with fungal disease symptoms were seen in all the farms visited during the survey, thus a prevalence of 100%. The disease incidence varied from 54- 100%, while the severity ranged from 20- 55%. Two genera of fungi were isolated from the diseased plants viz: Chaetomium sp. and Bipolaris sp.
Conclusion: Chaetomium and Bipolaris are associated with fungal symptoms in diseased sugarcanes hence any management plans geared towards the improvement of sugarcane production in this area must include control measures for these fungi.
Rituximab in kidney disease and transplant
Authors: Chauhan Kajal , Mehta Anita A. 
Published: March 2019

AbstractRituximab is a chimeric monoclonal antibody that binds toCD20 antigen of B‐cells. It depletes the level of mature B‐cells by various mechanisms such as mediation of antibody‐dependent cellular cytotoxicity, complement‐dependent cytotoxicity, and B‐cell apoptosis. Rituximab is aUSFDAapproved drug for clinical use in non‐Hodgkin's B‐cell lymphoma (NHL), rheumatoid arthritis, chronic lymphocytic leukemia (CLL), granulomatosis with polyangiitis and pemphigus vulgaris. It is also known for its “off label” use in renal disease and renal transplant worldwide. However, the exact mechanisms by which it exerts its effect in the aforementioned condition remain unclear but may be related to its long‐term effects on plasma cell development and the impact on B‐cell modulation of T cell responses. This review discusses the current use of rituximab in renal disease and renal transplantation, and its potential role in novel therapeutic protocols.

Published: March 2019

AbstractThere is a pressing need for new computational tools to integrate data from diverse experimental approaches in structural biology. We present a strategy that combines sparse paramagnetic solid‐state NMR restraints with physics‐based atomistic simulations. Our approach explicitly accounts for uncertainty in the interpretation of experimental data through the use of a semi‐quantitative mapping between the data and the restraint energy that is calibrated by extensive simulations. We apply our approach to solid‐state NMR data for the model protein GB1 labeled with Cu2+‐EDTA at six different sites. We are able to determine the structure to 0.9 Å accuracy within a single day of computation on a GPU cluster. We further show that in some cases, the data from only a single paramagnetic tag are sufficient for accurate folding.

Published: March 2019

AbstractGreat success has been achieved in recent years in the development of synthetic or assembled nanobiomaterials. Among these, biomolecule‐based nanoarchitectures with special optical property are of particular interest. Here, we demonstrate that vitamin B2 nanocrystals assembled as nanorods can be obtained with precise control. Excitingly, such one‐dimensional nanostructures not only exhibit intrinsic optical waveguiding properties but also the ability to sensitize oxygen to produce reactive oxygen species. With these properties, we applied the obtained vitamin B2 nanorods under remotely localized light illumination into single tumour cells in vitro for anticancer photodynamic therapy. Further, vitamin B2 nanorods were explored for in vivo photodynamic therapy by using a tumour model. With such bionanostructures, new features and functions of vitamin B2 and its derivatives have been developed.

Published: March 2019

AbstractA palladium‐catalyzed enantioselective intramolecular σ‐bond cross‐exchange between C−I and C−C bonds is realized, providing chiral indanones bearing an alkyl iodide group and an all‐carbon quaternary stereocenter. Pd/TADDOL‐derived phosphoramidite is found to be an efficient catalytic system for both C−C bond cleavage and alkyl iodide reductive elimination. In addition to aryl iodides, aryl bromides can also be used for this transformation in the presence of KI. Density‐functional theory (DFT) calculation studies support the ring‐opening of cyclobutanones occuring through an oxidative addition/reductive elimination process involving PdIVspecies.

Published: March 2019

AbstractB(npy)Ar2 (npy=2‐(naphthalen‐1‐yl)pyridine) compounds bearing various nonbulky aryl groups undergo a clean and sequential two‐step photoisomerization in which two aryl substituents on boron migrate to a carbon atom of the naphthyl moiety. The second isomerization step is the first example of a reversible photoisoermization between a borepin and a borirane. Both steric and electronic factors have been found to have a great impact on this photoreactivity. Furthermore, the borirane isomer reacts with oxygen, forming a rare oxaborepin dimer.

Authors: Wei Wenbo , Bai Feng , Fan Hongyou 
Published: March 2019

AbstractSelf‐assembly of anisotropic plasmonic nanomaterials into ordered superstructures has become popular in nanoscience because of their unique anisotropic optical and electronic properties. Gold nanorods (GNRs) are a well‐defined functional building block for fabrication of these superstructures. They possess important anisotropic plasmonic characteristics that result from strong local electric field and are responsive to visible and near‐IR light. There are recent examples of assembling the GNRs into ordered arrays or superstructures through processes such as solvent evaporation and interfacial assembly. In this Minireview, recent progress in the development of the self‐assembled GNR arrays is described, with focus on the formation of oriented GNR arrays on substrates. Key driving forces are discussed, and different strategies and self‐assembly processes of forming oriented GNR arrays are presented. The applications of the oriented GNR arrays in optoelectronic devices are also overviewed, especially surface enhanced Raman scattering (SERS).

Published: March 2019

AbstractFinding appropriate stimuli for controlling the breathing behavior of flexible metal–organic frameworks (MOFs) is highly challenging. Herein, we report the solvent‐induced changes in the particle size and stability of different breathing phases of the MIL‐53 series, a group of flexible MOFs. A water/dimethylformamide (DMF) ratio is tuned to synthesize members of the MIL‐53 series which have different behaviors. The breathing is explored by high‐pressure methane sorption tests. Increasing DMF concentration decreases MOF particle size and increases the stability of the porous phases, boosting the 5.8–65 bar sorption difference of methane, which is required for natural‐gas delivery.

Published: March 2019

AbstractThe dynamics of DNA and RNA structures in live cells are important for understanding cell behaviors, such as transcription activity, protein expression, cell apoptosis, and hereditary disease, but are challenging to monitor in live organisms in real time. The difficulty is largely due to the lack of photostable imaging probes that can distinguish between DNA and RNA, and more importantly, are capable of crossing multiple membrane barriers ranging from the cell/organelle to the tissue/organ level. We report the discovery of a cationic carbon quantum dot (cQD) probe that emits spectrally distinguishable fluorescence upon binding with double‐stranded DNA and single‐stranded RNA in live cells, thereby enabling real‐time monitoring of DNA and RNA localization and motion. A surprising finding is that the probe can penetrate through various types of biological barriers in vitro and in vivo. Combined with standard and super‐resolution microscopy, photostable cQDs allow time‐lapse imaging of chromatin and nucleoli during cell division and Caenorhabditis elegans (C. elegans) growth.

Published: March 2019

HKUST‐1‐Cu synthesized in the presence and absence of P‐123 trough solvotermal method. After characterization using some different microscopic and spectroscopic techniques such as XRD, FT‐IR, SEM, ICP, BET and TEM its catalytic activity was investigated in the oxidative coupling of benzyl alcohol, benzaldhyde, benzoic acid, styrene and phenyl acetylene with N,N‐dialkylformamides for the preparation of N,N‐dimethylformamides. Different derivatives of tertiary amides were synthesized in moderate to good yields in the presence of just ~0.28 mol% of this catalytic system. Reusability of the synthesized catalysts was examined and catalysts were reusable for 8 times without significant decrease in optimized conditions.

Published: March 2019

Hand‐held devices have revolutionized communication and education in the last decade. Consequently, mobile learning (m‐learning) has become popular among medical students. Nevertheless, there are relatively few studies assessing students' learning outcomes using m‐learning devices. This observational study presents an anatomy m‐learning tool (eMed‐App), an application developed to accompany an anatomy seminar and support medical students' self‐directed learning of the skeletal system. Questionnaire data describe where, how frequently, and why students used the app. Multiple choice examination results were analyzed to evaluate whether usage of the app had an effect on test scores. The eMed‐App application was used by 77.5% of the students, mainly accessed by Android smartphones, and at students' homes (62.2%) in order to prepare themselves for seminar sessions (60.8%), or to review learning content (67%). Most commonly, students logged on for less than 15 minutes each time (67.8%). Frequent app users showed better test results on items covering eMed‐App learning content. In addition, users also achieved better results on items that were not related to the content of the app and, thus, gained better overall test results and lower failure rates. The top quartile of test performers used the eMed‐App more frequently compared to students in lower quartiles. This study demonstrated that many students, especially the high‐performing ones, made use of the eMed‐App. However, the app itself did not result in better outcomes, suggesting that top students might have been more motivated to use the app than students who were generally weak in anatomy.
H∞ output feedback control for stochastic systems with randomly occurring convex‐bounded uncertainties and channel fadings
Authors: Jiang Xiangli , Xia Guihua , Feng Zhiguang , Li Tao 
Published: March 2019

AbstractIn this paper, the H∞ output feedback control problem for a class of stochastic discrete‐time systems with randomly occurring convex‐bounded uncertainties and channel fadings is investigated. A sequence of mutually independent random variables with known probabilistic distributions are utilized to describe the randomness that convex‐bounded uncertainties appear in practical systems. The measurements with channel fadings are given by a stochastic Rice fading model which is regulated by a set of random variables with certain probability density functions. The purpose of this paper is to design an output feedback controller such that the closed‐loop control system is asymptotically stable with a prescribed H∞ performance level. The less conservative results are obtained by employing the stochastic Lyapunov technique. Numerical examples are presented to illustrate effectiveness of the proposed approach.

Published: March 2019

Abstract

Background
Previous lower abdominal surgery is considered a relative contraindication to laparoscopic totally extraperitoneal (TEP) inguinal hernia repair. This was a meta-analysis of studies comparing the feasibility and safety of TEP repair between patients with (PS), and without (NS) a history of lower abdominal surgery.

Methods
A systematic literature search was undertaken for studies comparing the outcome of TEP inguinal hernia repair in patients with, and without previous lower abdominal surgery. Data on postoperative outcomes were extracted and compared by meta-analysis. Odds ratios (ORs) and mean differences with 95 per cent confidence intervals were calculated.

Results
Seven comparative cohort studies were identified, involving a total of 1657 procedures (PS 326, NS 1331). There was a statistically significant difference between PS and NS favouring the NS group with regard to both primary outcomes: intraoperative morbidity (OR 2·85, 95 per cent c.i. 1·19 to 6·80; P = 0·02; 7 studies; I2 = 33 per cent), and postoperative morbidity in the multiport subgroup (OR 2·14, 1·28 to 3·58; P = 0·004; 5 studies; I2 = 0 per cent). For the secondary endpoints conversion rate, peritoneal tears, major intraoperative bleeding, postoperative haematoseroma and delay in return to normal activities, there was a statistically significant difference favouring the NS group.

Conclusion
This study suggests that patients with previous lower abdominal surgery who need hernia repair get less benefit from TEP repair than those with no history of surgery.
A triple‐win scenario for horizontal collaboration in logistics: Determining enabling and key success factors
Authors: Palmieri Antonio , Pomponi Francesco , Russo Angeloantonio 
Published: March 2019

AbstractHorizontal collaborations emerged as a new strategic option in the logistics sector during the last decade. However, successful implementation of horizontal collaborations is far from a developed issue due to several barriers that exist or emerge when setting up such collaborative projects. This study aims at identifying the enabling factors supporting successful implementation of horizontal collaborations in the logistics sector, and in identifying key success factors that logistics service providers (LSPs) should consider. Results from a within‐ and cross‐case analysis of two horizontal collaboration projects in the contract logistics sector support the proposed theoretical framework, highlighting both enabling and key success factors of horizontal collaborations. The former refers to factors that are related to LSPs, customers, and industries, whereas the latter results in a triple‐win scenario characterised by LSP competences, trust, and environmental management orientation of successful horizontal collaboration projects.
