Published: August 2024

This study investigates the modulatory effects of morphine and Xylopia aethiopica extract on kappa opioid receptors (KOR), delta opioid receptors (DOR), pain hypersensitivity, and motor functions in Wistar rats. We utilized three experimental groups: a control group receiving distilled water, a morphine group receiving either low (5 mg/kg) or high (10 mg/kg) doses after inducing pain, Xylopia aethiopica group received either 25 mg/kg or 50 mg/kg of hydromethanolic extract following similar pain induction. Pain perception was quantified using the tail flick test and Analgesy-Meter while motor functions were assessed through the Rotarod and Climbing/Beam Walk tests. Additionally, molecular docking studies were performed on selected compounds from Xylopia aethiopica to determine their binding affinities to opioid receptors using Vina. Results demonstrated that morphine and Xylopia aethiopica significantly increased tail flick response times, indicating notable analgesic effects, while improving motor functions particularly in animals treated with higher doses of Xylopia aethiopica. Molecular analysis revealed potential interactions between bioactive compounds and opioid receptors, suggesting further therapeutic applications. These findings highlight the potential of Xylopia aethiopica as a natural analgesic and its implications in managing pain and associated motor deficits, the findings further revealed that Morphine and not Xylopia aethiopica is implicated in pain hypersensitivity after long term exposure. Further research should pay attention on improving the pharmacological profiles of the identified compounds for clinical use.
Roadside Testing: Kits for Drugs
Authors: Verstraete Alain G. 
Published: December 2014

Abstract

Most onsite oral fluid (OF) drug tests are based on lateral flow immunoassays; with a few tests, the presence of a line means the presence of the drug; however with many, the presence of a line means that the drug is not present. In the past 15 years, there has been slow but steady improvement. The first tests were derived from urine drug tests and had many failures (due to the viscosity of OF) and lacked reliability, particularly for cannabis. Nowadays, the reliability has improved much and one of the tests can detect the presence of tetrahydrocannabinol (THC) in OF for up to 22 h after last use at a cutoff of 5 µg l
−1
. Onsite OF drug tests are now part of the legal procedure for detecting drugged drivers in several countries in Europe and in five Australian states. There are still a few issues that need to be studied further and resolved before onsite OF drug tests become as convenient as breathalyzers: a shorter and less complex test sequence and the need for a very small sample in order to perform the test in people with dry mouth.
Hypervalent Iodine Reagents Enable Chemoselective Deboronative/Decarboxylative Alkenylation by Photoredox Catalysis
Authors: Huang Hanchu , Jia Kunfang , Chen Yiyun 
Published: December 2014

AbstractChemoselective C(sp3)C(sp2) coupling reactions under mild reaction conditions are useful for synthesizing alkyl‐substituted alkenes having sensitive functional groups. Reported here is a visible‐light‐induced chemoselective alkenylation through a deboronation/decarboxylation sequence under neutral aqueous reaction conditions at room temperature. This reaction represents the first hypervalent‐iodine‐enabled radical decarboxylative alkenylation reaction, and a novel benziodoxole‐vinyl carboxylic acid reaction intermediate was isolated. This C(sp3)C(sp2) coupling reaction leads to aryl‐and acyl‐substituted alkenes containing various sensitive functional groups. The excellent chemoselectivity, stable reactants, and neutral aqueous reaction conditions of the reaction suggest future biomolecule applications.
Time‐dependent exhaust steam temperature profile to mitigate fouling
Authors: Srivastava Divya 
Published: December 2014

AbstractIn sugar industries, a decrease in the exit liquor concentration is observed because of fouling in multiple‐effect evaporator (MEE) systems, which finally decreases the yield of the MEE system. In the present work, a time‐dependent exhaust steam temperature profile has been developed to compensate the ill effect of fouling. In the suggested temperature profile, the temperature of exhaust steam has been raised daily throughout the cycle of operation to achieve a constant exit liquor concentration. Further, the main drawback with this strategy is the increase in fouling resistance. For this purpose, an increase in foulant thickness has been determined, and it is found that only 0.4‐mm foulant thickness has been increased with the suggested strategy, and it will not cost any extra effort in cleaning, and with this strategy, constant exit liquor concentration can be achieved.

Assessing the Financial Landscape for the Association of Southeast Asian Nations Economic Community, 2015
Authors: Lee Choong Lyol , Takagi Shinji 
Published: December 2014

AbstractThe article assesses Association of Southeast Asian Nations (ASEAN)'s financial landscape and considers issues related to regional financial cooperation. Although the ASEAN Economic Community is expected to come into force by the end of 2015, given the large disparity between the more and the less advanced member countries, regional financial integration in ASEAN can only be an evolutionary process. Regional cooperation is needed not only to help integrate the region financially but also to manage the attendant risks. Areas of cooperation must include, among others, establishing common licensing standards for financial institutions and creating region‐wide systems for deposit insurance, credit rating, financial market supervision, payment and settlement, and consumer protection.
Minimierung von Hitzestress und Heizenergiebedarf in mechanisch belüfteten Mastgeflügelställen

Published: December 2014

AbstractDas Stallklima hat einen wesentlichen Einfluss auf die Gesundheit der eingestallten Nutztiere. Neben der erforderlichen Stalllüftung zur Gewährleistung von genügend Frischluft ist speziell in den Aufzucht‐ oder Mastbeginnphasen eine ausreichend hohe Stalltemperatur erforderlich. Für den wirtschaftlichen Betrieb von beheizten Nutztierställen stellt sich deshalb, wie bei jeder Gebäudekonzeption, die Frage nach der optimalen Gestaltung und Abstimmung von Lüftungssystem und Wärmedämmung der Gebäudehülle. Während sich die Anwendung von Standardprogrammen zur dynamisch‐thermischen Simulation von Wohn‐ und Verwaltungsbauten stetig durchsetzt, werden sie bei der Planung von Stallbauten bisher nur vereinzelt eingesetzt. In dem vorliegenden Artikel wird am Beispiel eines Mastgeflügelstalls der Einsatz von dynamisch‐thermischen Simulationen dokumentiert. Dazu wird für ein Stall‐Modell der Betrieb über ein Kalenderjahr simuliert und bewertet. Betrachtet werden drei Aspekte: (1) die Herausforderungen bei der Simulation von Ställen im Vergleich zur Simulation von Wohn‐ und Verwaltungsbauten; (2) die Qualität der Simulationsresultate im Vergleich zu gemessenen Betriebswerten und (3) die Bewertung der Einflüsse von Wärmedurchgangskoeffizienten von Dach und Außenwänden sowie der Rückwärmezahl einer Wärmerückgewinnungsanlage in der Abluft in Bezug auf den Jahresheizenergiebedarf.Minimizing heat stress and energy demand for heating in mechanically ventilated poultry animal houses. The indoor environmental conditions in mechanically ventilated animal houses have a fundamental impact on health and well‐being of the kept animals. Apart from the need to sufficiently ventilate the animal house it is important to maintain an indoor air temperature which corresponds to animal growth, particularly at the beginning of the fattening period. Thus, in order to provide an appropriate climate within the animal house building insulation, ventilation system and heating system operation need to be integrated and optimized. Whilst dynamic‐thermal simulation programs are increasingly used for the design of residential and office buildings, they are rarely used for the design of animal houses. This article illustrates the benefit using the dynamic‐thermal simulation on the example of a mechanically ventilated poultry house. Three aspects are being discussed: (1) the challenges in modelling poultry houses opposed to modelling residential and office buildings; (2) the quality of simulated performance data compared to measured data and (3) the impact of the heat recovery system COP as well as heat transfer coefficients of roof and walls on energy demand for heating and overheating risk. The results show the dominating impact of the ventilation system operation on energy demand for heating and the benefit of a high thermal storage capacity of the walls to eliminate life‐threatening heat stress for the poultry.
Essential‐Oil Composition of the Fruits of Six Heracleum L. Species from Iran: Chemotaxonomic Significance
Authors: Radjabian Tayebeh , Salimi Azam , Rahmani Nosrat 
Published: December 2014

AbstractThe fruit essential oils of Heracleum persicum, H. rechingeri, H. gorganicum, H. rawianum, H. pastinacifolium, and H. anisactis from Iran were obtained by hydrodistillation and characterized by GC‐FID and GC/MS analyses. The oils of the six species were compared to determine the similarities and differences among their compositions. Overall, 36 compounds were identified in the fruit oils, accounting for 92.40–96.74% of the total oil compositions. Aliphatic esters constituted the main fraction of the oils (86.61–94.31%), with octyl acetate and hexyl butyrate as the major components. The oil compositions of species belonging to section Pubescentia (H. persicum, H. gorganicum, and H. rechingeri) were discriminated by equally high contents of both octyl acetate (13.84–20.48%) and hexyl butyrate (17.73–38.36%). On the other hand, the oils of H. rawianum, H. pastinacifolium and H. anisactis, belonging to section Wendia, showed lower hexyl butyrate contents (3.62–6.6%) and higher octyl acetate contents (48.71–75.36%) than the former. Moreover, isoelemicin was identified at low amounts (0.10–2.51%) only in the oils of the latter species. The differences in the oil composition among the six species were investigated by hierarchical cluster and principal component analyses, which indicated that the oil composition confirmed well the taxonomical classification based on the morphological and botanical data, and, thus, may provide a reliable marker to discriminate Heracleum species at the intersectional level.

AbstractSeparation of challenging mixtures using metal–organic frameworks can be achieved by an entropy‐driven mechanism, where one of the components can arrange into a “face‐to‐face” stacking, thus reducing its “footprint” and reaching a higher saturation loading.
Evaluating the spectrum of periodic pulling in subharmonic resonant LC circuits
Authors: Buonomo Antonio , Lo Schiavo Alessandro 
Published: December 2014

SummaryWe analyze the features of the oscillations arising in forced inductor–capacitor (LC) oscillators when they operate in the periodic pulling mode, under the action of a weak injection signal. In radio frequency integrated circuits, both voltage‐controlled oscillators subject to undesired couplings and injection‐locked frequency dividers behave like forced LC oscillators. These are modeled as second‐order driven oscillators working in the subharmonic (secondary) resonance regime. The analysis is based on the generalized Adler's equation, which we introduce to describe the phase dynamics of dividers of any division ratio and to derive closed‐form expressions for the spectrum components of the system's oscillatory response. We show that the spectrum is double‐sided and asymmetric, unlike the single‐sided spectrum of systems with primary resonance. Numerical and experimental results are given to validate the presented results, which significantly generalize those available in the literature. Copyright © 2014 John Wiley & Sons, Ltd.

The crystal structures of 2, 4–6, 7·8, 9–14, and 16 are reported. The different coordination modes in their solid‐state structures are discussed and generally compared to the solution behavior of those species.
Pentafluorosulfanyltrimethylsilane: A Nonexistent Molecule?
Authors: Ghosh Abhik , Conradie Jeanet 
Published: December 2014

AbstractFrom a medicinal chemistry standpoint, the pentafluorosulfanyl (SF5) group is justifiably viewed as a “super‐trifluoromethyl” group. Unfortunately, synthetic routes to this remarkable, strongly electron‐withdrawing, highly lipophilic substituent are limited. In this study, DFT calculations with large basis sets indicate that reagents of the form MSF5, where M = Me3Si, Li, Cu, MeZn, MeCd, and MeHg, are both thermodynamically and kinetically unstable. Attempts to synthesize reagents such as pentafluorosulfanyltrimethylsilane (TMSSF5) and pentafluorosulfanylcopper (CuSF5) are therefore likely to fail.

Published: December 2014

AbstractA selective and sensitive electroanalytical method was developed for arsenic determination based on a nanogold (AuNP) modified solid carbon paste working electrode (SCPE) modified in two steps (i) physisorption and (ii) additional electrodeposition of nanogold particles in the presence of iodide. Copper(II) interference was solved by covering the gold layer by a self assembled mono layer (SAM) of glutathione. Using DPASV a linear response of the signal was obtained as a function of As(III) in the concentration range 0.05–20 µM (4–1498 ppb) with a limit of detection of 0.01 µM (0.9 ppb). Sample stirring and degassing were not needed. Application to the determination of arsenic(III) and (V) in underground water samples from Burkina Faso was successfully achieved.

Published: December 2014

AbstractAn “abiotic” biofuel cell composed of catalytic electrodes modified with inorganic nanoparticles (NPs) deposited on carbon black (CB) was used to activate a wireless information transmission system. The cathode and anode were made of carbon paper modified with Pt‐NPs/CB and buckypaper modified with Au80Pt20‐NPs/CB, respectively. The cathode/anode pair was implanted in orange pulp extracting power from its content (glucose and fructose in the juice). The open circuit voltage, Voc, short circuit current density, jsc, and maximum power produced by the biofuel cell, Pmax, were found as 0.36 V, 1.3 mA cm−2 and 182 µW, respectively. The voltage produced by the biofuel cell was amplified with an energy harvesting circuit and applied to a wireless transmitter. The present study continues the research line where different implantable biofuel cells are used for activation of electronic devices.

AbstractMany flavour regulations around the world contain a list of so‐called ‘restricted substances’ (RS), i.e. substances that occur naturally in source materials for flavourings and food ingredients with flavouring properties, but whose presence in certain foods is restricted and/or for which maximum levels are set, for example, the European regulation 1334/2008. Only a few publications refer to the determination of RS in compound flavourings or their raw materials, and the latter only concern the analysis of one or two individual RS in single essential oils. The Working Group on Methods of Analysis of the International Organization of the Flavor Industry (IOFI) has developed a method for the rapid routine determination of β‐asarone, coumarin, menthofuran, methylchavicol, methyleugenol, pulegone, safrole and α‐ and β‐thujones in flavourings and their raw materials by gas chromatography‐mass spectrometry (GC‐MS), using selected‐ion monitoring and internal standards. The method has been evaluated by nine flavour‐industry laboratories using a complex surrogate flavouring containing all of the above analytes, at concentrations that would be likely to produce levels in finished foods of around typical maximum limits for these RS. Results were obtained from a total of 15 columns and sets of analytical conditions, using 11 GC/MS instruments, with in each case a determination of the analyte in two versions of the flavouring. With reproducibility relative standard deviations (RSDR) of less than about 20%, and recoveries of 80–120%, the method performance can be considered as satisfactory for rapid routine checks on the levels of restricted substances in compound flavourings. The method is intended for flavour‐industry laboratories in order for them to fulfil their obligation to inform food‐industry clients of the amounts of these substances in commercial flavourings, but is not intended for their analysis in finished foods.
