Published: October 2024

Background: Dynamic balance is essential when performing activities that require rapid acceleration, rapid deceleration, and rapid changes in direction, such as basketball. This allows athletes to adjust their posture and footing quickly during high-intensity activities, reducing the risk of injury. The objective of our study is to determine the correlation between dynamic balance and female basketball players' jump performance, sprints, and agility abilities. Methods: The dynamic balance of 14 female basketball players in Saudi Arabia, ages 18 to 23, was measured using the modified star excursion balance test (mSEBT). Jump performance, sprints, and agility skills were assessed using five tests: a vertical jump test (VJT), a standing board jump test (SBJT), a ten-meter sprint test (10mST), and a T-Agility test. Result: Dynamic balance was positively correlated with vertical jump, broad jump, and negatively correlated with the 10-m sprint and T-agility tests. Conclusion: Dynamic balance is a significant factor affecting performance in specific tests. This emphasizes the importance of incorporating dynamic balance exercises into training programs for basketball players.Arabia.

Environmental Management Systems Implementation in Selected Industries in Uganda
Authors: Alhadhuri Nadia , Barakagira Alex , Nabukonde Ameria 
Published: October 2024

Environmental Management Systems (EMS) were of less significant focus in the earlier times because of the less degradation the industrial activities caused to the environment. However, the EMS evolved over time due to a variety of factors, including changing consumer demands, regulatory requirements, and increased awareness of environmental issues. The current study was set to examine the EMS implementation during the production processes in selected industries in Uganda. The study was based on three objectives: to determine the types of pollution control environmental management systems implemented in the selected industries in Uganda; to explore the benefits obtained as a result of the implementation of the pollution control environmental management systems during the production of goods in Uganda; and to examine the challenges faced during the implementation of the pollution control environmental management systems in the selected industries in Uganda. The study randomly selected three manufacturing industries, X, Y, Z and targeted a population of 100 members of staff. A total of the 76 respondents participated in the study. A case study research design was employed and both quantitative and qualitative approaches of data collection were used. A questionnaire and interview guide were used to collect data from the respondents. Data were entered into a Statistical Package for Social Scientists (SPSS) for analysis. Data were analyzed using descriptive statistics and multiple regression. The study findings revealed that scrubbers and filters, regulatory command and control, use of energy efficient technologies and efficient waste management systems are some of the pollution control mechanisms implemented by the industries. The benefits that accrued as a result of implementing the EMS on production processes within the factories include: cost savings due to efficient resource use, enhanced industry’s reputation, improved product quality, customer satisfaction among others. The challenges encountered during EMS implementation include; insufficient technical expertise, inadequate infrastructure, high operational costs, limited financial resources, and employee resistance to embrace the new technologies. The presence of the challenges encountered during EMS implementation are likely to stifle full attainment of the associated outcomes among the industries in Uganda. Hence, awareness of the benefits as a result of implementation of EMS should be created amongst all the employees for effective implementation. Also, industries should create a clear environmental policy that aligns the industrial goals and regulatory requirements. The institution concerned with implementation of the EMS should constantly monitor all the industries operating in Uganda for the uniform implementation of the systems.

Published: April 2018

AbstractThe development of Au/AgI dimeric nanoparticles (NPs) is reported for highly selective colorimetric detection of hydrogen sulfide (H2S). The detection mechanism is designed by taking advantage of the chemical transformation of AgI to Ag2S upon reacting with sulfide, which leads to a shift in the plasmonic band of the attached Au NPs. The plasmonic shift is accompanied by a color change of the solution from purplish red to blue and finally to light green depending on the concentration of sulfide, thus enables a naked‐eye readout and UV–vis quantitation of the sulfide exposure. The Au/AgI dimeric NPs are further immobilized in agarose gels to produce test strips, which can be used for both naked‐eye readout and quantitative detection of sulfide using UV–vis spectroscopy thanks to its transparency in the visible region. Compared to commercial Pb(Ac)2 test papers, the agarose gel strip has superior performance for detecting sulfide in terms of sensitivity, selectivity, stability, and fidelity. The agarose gel is also capable of detecting gaseous H2S at important concentration thresholds, suggesting its practicability in real life applications. The potential of agarose gels is further highlighted by its ability in the enrichment and colorimetric detection of gaseous H2S released during cell cultivation.

AbstractUtilization of self‐healing chemistry to develop synthetic polymer materials that can heal themselves with restored mechanical performance and functionality is of great interest. Self‐healable polymer elastomers with tunable mechanical properties are especially attractive for a variety of applications. Herein, a series of urea functionalized poly(dimethyl siloxane)‐based elastomers (U‐PDMS‐Es) are reported with extremely high stretchability, self‐healing mechanical properties, and recoverable gas‐separation performance. Tailoring the molecular weights of poly(dimethyl siloxane) or weight ratio of elastic cross‐linker offers tunable mechanical properties of the obtained U‐PDMS‐Es, such as ultimate elongation (from 984% to 5600%), Young's modulus, ultimate tensile strength, toughness, and elastic recovery. The U‐PDMS‐Es can serve as excellent acoustic and vibration damping materials over a broad range of temperature (over 100 °C). The strain‐dependent elastic recovery behavior of U‐PDMS‐Es is also studied. After mechanical damage, the U‐PDMS‐Es can be healed in 120 min at ambient temperature or in 20 min at 40 °C with completely restored mechanical performance. The U‐PDMS‐Es are also demonstrated to exhibit recoverable gas‐separation functionality with retained permeability/selectivity after being damaged.

AbstractAs a new category of solids, crystalline materials constructed with amorphous building blocks expand the structure categorization of solids, for which designing such new structures and understanding the corresponding formation mechanisms are fundamentally important. Unlike previous reports, new amorphous carbon clusters constructed ordered carbon phases are found here by compressing C8H8/C60 cocrystals, in which the highly energetic cubane (C8H8) exhibits unusual roles as to the structure formation and transformations under pressure. The significant role of C8H8 is to stabilize the boundary interactions of the highly compressed or collapsed C60 clusters which preserves their long‐range ordered arrangement up to 45 GPa. With increasing time at high pressure, the gradual random bonding between C8H8 and carbon clusters, due to “energy release” of highly compressed cubane, leads to the loss of the ability of C8H8 to stabilize the carbon cluster arrangement. Thus a transition from short‐range disorder to long‐range disorder (amorphization) occurs in the formed material. The spontaneous bonding reconstruction most likely results in a 3D network in the material, which can create ring cracks on diamond anvils.

AbstractA one‐step, I2‐promoted P−H phosphorylation and oxygenation of phosphinecarboxamides to give carbamoylphosphonates was achieved. This transformation exhibits exceptional substrate generality and functional group compatibility and affords good to excellent yields of the desired phosphonates. Notably, cyclic carbamoylphosphonates can be obtained from diols. The mechanism was investigated using IR, 1H and 31P NMR spectroscopy.magnified image

AbstractIn this study, we investigated the incidence and prognostic impact of monosomal karyotype (MK) in 405 higher‐risk Myelodysplastic Syndromes (MDS) patients treated with 5‐AZA. The MK was present in 66 out of 405 (16.3%) patients, most of whom had complex karyotype (CK). MK was strongly associated with CK and the cytogenetic risk defined according to IPSS‐R, as well as with high‐risk disease, according to IPSS (P = .029), IPSS‐R (P < .001), and WPSS (P < .001) classification systems. The overall response rate (ORR) was not different between MK+ and MK– patients (46.6% vs. 46.2%). At 28 months median follow‐up, the median duration of response was 11 months in the entire cohort, 9.5 months in MK+ patients and 11 months in MK‐patients (P = .024). The estimated median time to transformation to acute myeloid leukemia for MK+ patients was 17 months vs. 23 months for MK– patients (P = .025). The estimated median OS for MK+ patients was 12 months vs. 18 months for MK– patients (P < .001). Multivariate Cox regression analysis revealed that performance status (P < .001), IPSS‐R (P < .001), and MK (P = .002) were independently associated with overall survival (OS). In a subgroup consisting of high and very‐high risk patients according to IPSS‐R, MK– patients showed better OS rates compared to MK+ patients (estimated median OS: 17 months vs. 12 months, P = .002). In conclusion, we found that MK is associated with reduced OS in patients with higher‐risk MDS treated with 5‐AZA. Furthermore, we showed that in MDS with high or very‐high IPSS‐R risk score, MK can further distinguish patients with worse outcome.

Published: April 2018

AbstractChromones and coumarins are privileged scaffolds that are widely distributed in natural products, synthetic building blocks, pharmaceutical agents, and functional materials. Chromones and coumarins have chemically distinct C−H bonds that can be converted into valuable functional groups for the purpose of constructing compounds with diverse pharmacological profiles. Recent advances in the development of methods and an understanding of the innate electronic properties of chromones and coumarins have led to approaches that provide high levels of site‐selectivity. This focus review highlights recent innovative strategies for the efficient modification of these structural frameworks through site‐selective C−H bond functionalizations.

Authors: Willett Sarah A. , Akoh Casimir C. 
Published: April 2018

AbstractStructured lipids (SL) were produced using menhaden oil and capric acid or ethyl caprate as the substrate. Enzymatic reaction conditions were optimized using the Taguchi method L9 orthogonal array with three substrate molar ratio levels of capric acid or ethyl caprate to menhaden oil (1:1, 2:1, and 3:1), three enzyme load levels (5, 10, and 15% [w/w]), three temperature levels (40, 50, and 60 °C), and three reaction times (12, 24, 36 hours). Recombinant lipase from Candida antarctica, Lipozyme® 435, and sn‐1,3 specific Rhizomucor miehei lipase, Lipozyme® RM IM (Novozymes North America, Inc., Franklinton, NC, USA), were used as biocatalysts in both acidolysis and interesterification reactions. Total and sn‐2 fatty acid compositions, triacylglycerol (TAG) molecular species, thermal behavior, and oxidative stability were compared. Optimal conditions for all reactions were 3:1 substrate molar ratio, 10% [w/w] enzyme load, 60 °C, and 16 hours reaction time. Reactions with ethyl caprate incorporated significantly more C10:0, at 30.76 ± 1.15 and 28.63 ± 2.37 mol% versus 19.50 ± 1.06 and 9.81 ± 1.51 mol%, respectively, for both Lipozyme® 435 and Lipozyme® RM IM, respectively. Reactions with ethyl caprate as substrate and Lipozyme® 435 as biocatalyst produced more of the desired medium‐long‐medium (MLM)‐type TAGs with polyunsaturated fatty acids (PUFA) at sn‐2 and C10:0 at sn‐1,3 positions.
Spinal Accessory Motor Neurons in the Mouse: A Special Type of Branchial Motor Neuron?
Authors: Watson Charles , Tvrdik Petr 
Published: April 2018

ABSTRACTThe spinal accessory nerve arises from motor neurons in the upper cervical spinal cord. The axons of these motor neurons exit dorsal to the ligamentum denticulatum and form the spinal accessory nerve. The nerve ascends in the spinal subarachnoid space to enter the posterior cranial fossa through the foramen magnum. The spinal accessory nerve then turns caudally to exit through the jugular foramen alongside the vagus and glossopharyngeal nerves, and then travels to supply the sternomastoid and trapezius muscles in the neck. The unusual course of the spinal accessory nerve has long prompted speculation that it is not a typical spinal motor nerve and that it might represent a caudal remnant of the branchial motor system. Our cell lineage tracing data, combined with images from public databases, show that the spinal accessory motor neurons in the mouse transiently express Phox2b, a transcription factor that is required for development of brain stem branchial motor nuclei. While this is strong prima facie evidence that the spinal accessory motor neurons should be classified as branchial motor, the evolutionary history of these motor neurons in anamniote vertebrates suggests that they may be considered to be an atypical branchial group that possesses both branchial and somatic characteristics.

Extracranial Course of the Facial Nerve Revisited
Authors: Martínez Pascual Paula , Maranillo Eva , Vázquez Teresa , Simon de Blas Clara , Lasso Jose Maria , Sañudo José Ramón 
Published: April 2018

ABSTRACTIntroduction: The extrapetrous course of the facial nerve has been a matter of study and debate since XIX century. Two different classifications have been classically proposed and widely accepted by most of the authors. Nevertheless, there are reported cases which do not fit in any of those. The aim of this study is to propose a new and useful classification. Material and methods: We have used 23 embalmed Caucasian adult cadavers (11 male and 12 female) belonging to the Bodies Donation and Dissecting Rooms Centre of the University Complutense of Madrid. The extra‐petrous facial nerve was dissected in the possible specimens resulting in 38 facial nerves. The studied parameters were length, diameter of divisions, terminal branches, and nerve connections. Results: In every specimen two main divisions were found, temporofacial and cervicofacial. They divided into five terminal branches from cranial to caudal: temporal, zygomatic, buccal, marginal or mandibular, and cervical. Based on the comparison with previous proposed classifications, we have unified the patterns in 12 types being the most frequent types the type 3 (eight cases, 21.05%), with connections between temporal, zygomatic and buccal branches and the type 8 (eight cases, 21.05%), a complex network between temporal, zygomatic, buccal, and mandibular branches. The number of terminal branches was so variable. Conclusion: We propose a new 12‐patterned classification which summarizes the previous ones. However, we consider that a good study of the number of terminal branches, connections between branches or with other cranial nerves are more useful for surgeons to avoid injuries to the facial nerve during surgery than complex classifications.

AbstractThe biological activity of three previously synthesized 17β‐carboxamide glucocorticoids (BG, BEG, and MPEA) was tested in vitro on mitogen stimulated and non‐stimulated peripheral blood mononuclear cells (MNCs) and granulocytes from human healthy donors, and the results were compared to the conventional glucocorticoid dexamethasone. The tested 17β‐carboxamide glucocorticoids did not induce decreases in MNC viability and proliferation, while modulation of reactive oxygen species (ROS) synthesis in granulocytes was dependent on the cell donor. The obtained results indicate the possibility of avoidance of strong lymphocyte suppression, which is generally recognized during administration of conventional glucocorticoids. Furthermore, the metabolism of the tested derivatives was predicted in silico. The predicted metabolites were synthesized and the in silico results were confirmed by in vitro evaluation of the metabolism of BG, BEG, and MPEA in human serum and in cultures of peripheral blood MNCs. The results of the biological activity and metabolism evaluation and of previous in vivo evaluations of biological activity indicate the soft drug nature of BG, BEG, and MPEA. In order to be fully considered as soft glucocorticoids, further investigations on the toxicity and activity of the formed metabolites are required.
2‐(4′‐Pyridyl‐N‐oxide)‐Substituted Hemithioindigos as Photoresponsive Guests for a Super Aryl‐Extended Calix[4]pyrrole Receptor
Authors: Moncelsi Giulia , Escobar Luis , Dube Henry , Ballester Pablo 
Published: April 2018

AbstractWe report the synthesis of two 2‐(4′‐pyridyl‐N‐oxide)‐substituted hemithioindigos (HTIs). We probed their photoisomerization by using UV/Vis and 1H NMR spectroscopy techniques. Light irradiation at λ=450 nm provoked the isomerization of the HTI Z isomer to the E counterpart to a large extent (≈80 % at the photostationary state). 1H NMR titration experiments revealed the formation of thermodynamically and kinetically stable 1:1 inclusion complexes of the (Z)‐HTI isomers with a super aryl‐extended host (association constant>104 m−1). Photoirradiation at λ=450 nm of the inclusion complexes induced the isomerization of the bound HTI N‐oxide to afford the (E)‐HTI⊂calix[4]pyrrole complex. We determined accurate association constant values for the 1:1 inclusion complexes of the (Z)‐ and (E)‐HTI isomers by using isothermal titration calorimetry experiments. The results showed that the stability constants of the (E)‐HTI complexes were 2.2–2.8‐fold lower than those of the (Z)‐HTI counterparts, which explains the lack of light‐induced release of the former to the bulk solution.

AbstractDer Fluss Ahse wird im Bereich des Kurparks Hamm durch einen Düker unter dem Datteln‐Hamm‐Kanal (DHK) geführt und mündet direkt im Anschluss in die Lippe. Die Dükeranlage befindet sich im Eigentum der Wasserstraßen‐ und Schifffahrtsverwaltung des Bundes (WSV). Aufgrund des hohen Bauwerksalters kann die Prüfung des Gesamtbauwerks nicht mehr stattfinden, da ein Trockenlegungs‐ und Betretungsverbot angeordnet wurde. Eine gefahrlose Begehung zum Zweck der Bauwerksprüfung ist nicht mehr möglich. Der Ersatz der Dükeranlage liegt im Wohl der Allgemeinheit, da der bestehende Düker aufgrund von Ablagerungen nicht mehr zweifelsfrei imstande ist, die Abflussmengen im Hochwasserfall abzuführen. Ein schadloser Wasserabfluss der Ahse, insbesondere der Hochwasserabfluss, ist durch einen zeitnahen Ersatzneubau zu gewährleisten. Der Bau des Dükers an gleicher Lage kann nicht ausgeführt werden, da in dem Fall während der Bauzeit kein Abfluss der Ahse zur Lippe gegeben ist. Ein vorübergehendes Einleiten der Ahse in den DHK ist nicht möglich, da unterschiedliche Wasserabflüsse zu hohen Wasserständen im Kanal führen. Aus diesen Gründen ist der Neubau mit einem Abstand von 60 m zum bestehenden Bauwerk geplant, um zu verhindern, dass Erschütterungen beim Neubau zu Beschädigungen des vorhandenen Dükers führen.
