Authors: Bako I. A. , Jamda M. A. , Audu O. , Araoye M. O. 
Published: May 2017

Abstract
The study was aimed at determining the HIV risk perception and sexual behaviour among commercial motorcyclists in Makurdi, Benue State, Nigeria. The study design was cross sectional study among 344 consenting, registered commercial motorcyclists, aged 18 years and above working in Makurdi, Benue State capital. A multistage sampling technique was used to select the respondents from a total of 5000 motorcyclists spread across 45 stations within Makurdi. Data was collected in September 2014 using structured interviewer administered questionnaire. Analysis was done with SPSS version 20.0. The mean age was 28.18 (± 7.94) years. Approximately 93% of the participants reported ever having sex. The average lifetime number of sexual partners was 8.9 (± 20.26) while 48.0% reported having had more than one sexual partner in the previous one year. A two third of the respondents (66.7%) reported use of condom during their last sex with a non-regular partner. Slightly less than a quarter (24.1%) of the respondents have paid to have sex in the previous one year. However only 29.6% perceived themselves as been at moderate or high risk of contracting HIV. There was significant association between risk perception and use of condom during last sex with any partner {OR-2.687 (95% CI= 1.337 - 5.400) p=0.005}. There is low personal risk perception despite high proportion of risky sexual behaviours among the respondents. HIV prevention interventions among commercial motorcyclists need to be more tailored and with the objective of building assertive skills in addition to imparting knowledge.

Abstract
The performance of state-owned enterprises (SOEs) is rated as an important component of the economic development in Indonesia. Indonesian government has set strategic steps to fix the financial value of the SOEs. Knowledge management is one of strategic implementation of SOEs. The result of the researcher’s analysis reveals that the implementation of the knowledge management does not always give a positive contribution to the performance of the SOEs. Accordingly, it is important to conduct a research related to the efforts taken in implementing knowledge management and its impacts on organizational performance of the SOEs. The main objective of this study is to figure out the relationship between knowledge management and organizational performance by involving organizational learning as the intervening variable. This study involves six state-owned enterprises in Indonesia. The total number of respondents successfully examined were 189 employees of the six state-owned enterprises. The data was processed by SEM technique using AMOS 22 Software and the result shows that knowledge management has a significant impact by 45% toward organizational performance, and organizational learning influences significantly by 44% on organizational performance.

Abstract
The aim of this study is to analyze the importance of effects and impact of seasonal fluctuations on income of farmers, workoccupation in farm and sales on apples activity for areas of Korça and Prizren , and in tomatos activities for areas Lushnja and Prizren. Lushnja area is one of the most popular areas of Albania on the quality of vegetable production. Seasonal effects that influence on the apples production in areas of Korça and Prizren and tomatos in areas of Lushnja and Prizren. Some seasonal effects comes as a result of weather conditions, pests and diseases, and are more expressed in those economic phenomenon such us: the volatility of price over year, to farmers income and to farmers work-occupation over a year. We also can say that the production of apples and tomatos in our country includes more intensive activities of production that require large investments. Their production cost turns out to be higher for manufacturers, but, while also enabling high levels of profit. Our estimates are based on data obtained from surveys, for 300 farmers, to make our evaluations we build some econometric models. In this paper we have used the model of seasonal indexes, where seasonal variation can be measured in terms of an index called the seasonal index. We have used these methods: seasonal indexes standard deviations, and econometric modeling. Also we have defined indicators and values of the variations coefficient. The variations coefficient is a relative indicator which expresses the ratio between to standard deviation size and arithmetic average of mass phenomenon.

Former le citoyen européen ? Réflexions sur le concept d’éducation civique dans le cadre de l’intégration politique transnationale de l’Europe
Authors: Heimpel Daniela 
Published: May 2017

Dans cet article, l’auteure s’interroge, du point de vue de la théorie politique, sur la possibilité de penser une éducation à la citoyenneté européenne. En 2009, le Comité économique et social européen a suggéré à l’Union européenne (UE) l’introduction d’une « instruction civique européenne commune » afin de « donner à ses citoyens un réel sentiment d’appartenance » à l’Europe. Si des programmes d’éducation civique existent au niveau national, leur transposition, de manière analogue, au cadre européen et à la citoyenneté européenne ne va pas de soi. En effet, et sans compter les raisons politico-pratiques, l’UE ne souscrit pas à la même logique de construction que jadis les États-nations. Il semble à la fois contre-productif et indésirable, quant au processus d’intégration européenne, d’attribuer à l’éducation le rôle qu’elle a pu avoir dans la construction étatique. De plus, l’UE présente quelques traits spécifiques qui posent des défis particuliers à l’application de l’éducation civique à la citoyenneté européenne ; en effet, ce type d’enseignement a traditionnellement été pensé à partir de présupposés stato-nationaux (catégories, questionnements et problèmes). En s’appuyant sur les travaux post- et transnationaux en études européennes et différents écrits sur le rôle des écoles dans la construction des États-nations et sur l’éducation civique en tant que problème éthique et politique, l’auteure entame ici une analyse de ces défis et offre quelques pistes pour repenser l’éducation civique dans le cadre européen.

ImportanceGuidelines for blood pressure (BP) measurement recommend arm support on a desk with the midcuff positioned at heart level. Still, nonstandard positions are used in clinical practice (eg, with arm resting on the lap or unsupported on the side).ObjectiveTo determine the effect of different arm positions on BP readings.Design, Setting, and ParticipantsThis crossover randomized clinical trial recruited adults between the ages of 18 and 80 years in Baltimore, Maryland, from August 9, 2022, to June 1, 2023.InterventionParticipants were randomly assigned to sets of triplicate BP measurements with the arm positioned in 3 ways: (1) supported on a desk (desk 1; reference), (2) hand supported on lap (lap), and (3) arm unsupported at the side (side). To account for intrinsic BP variability, all participants underwent a fourth set of BP measurements with the arm supported on a desk (desk 2).Main Outcomes and MeasuresThe primary outcomes were the difference in differences in mean systolic BP (SBP) and diastolic BP (DBP) between the reference BP (desk 1) and the 2 arm support positions (lap and side): (lap or side − desk 1) − (desk 2 − desk 1). Results were also stratified by hypertensive status, age, obesity status, and access to health care within the past year.ResultsThe trial enrolled 133 participants (mean [SD] age, 57 [17] years; 70 [53%] female); 48 participants (36%) had SBP of 130 mm Hg or higher, and 55 participants (41%) had a body mass index (calculated as weight in kilograms divided by height in meters squared) of 30 or higher. Lap and side positions resulted in statistically significant higher BP readings than desk positions, with the difference in differences as follows: lap, SBP Δ 3.9 (95% CI, 2.5-5.2) mm Hg and DBP Δ 4.0 (95% CI, 3.1-5.0) mm Hg; and side, SBP Δ 6.5 (95% CI, 5.1-7.9) mm Hg and DBP Δ 4.4 (95% CI, 3.4-5.4) mm Hg. The patterns were generally consistent across subgroups.Conclusion and RelevanceThis crossover randomized clinical trial showed that commonly used arm positions (lap or side) resulted in substantial overestimation of BP readings and may lead to misdiagnosis and overestimation of hypertension.Trial RegistrationClinicalTrials.gov Identifier: NCT05372328
Domain swapping: a mathematical model for quantitative assessment of structural effects
Authors: Roterman Irena , Stapor Katarzyna , Dułak Dawid , Konieczny Leszek 
Published: October 2024

The domain‐swapping mechanism involves the exchange of structural elements within a secondary or supersecondary structure between two (or more) proteins. The present paper proposes to interpret the domain‐swapping mechanism using a model that assesses the structure of proteins (and complexes) based on building the structure of a common hydrophobic core in a micelle‐like arrangement (a central hydrophobic core with a polar shell in contact with polar water), which has a considerable impact on the stabilisation of the domain structure built by domain swapping. Domains with a hydrophobicity system that is incompatible with the micelle‐like structure have also been identified. This incompatibility is the form of structural codes related to biological function.

AbstractOverproduction of reactive oxygen species (ROS) during reperfusion in ischemic stroke (IS) severely impedes neuronal survival and results in high rates of morbidity and disability. The effective blood‐brain barrier (BBB) penetration and brain delivery of antioxidative agents remain the biggest challenge in treating ischemic reperfusion‐induced cerebrovascular and neural injury. In this study, a metal‐organic framework (MOF) nanozyme (MIL‐101‐NH2(Fe/Cu)) with ROS scavenging activities to encapsulate neuroprotective agent rapamycin is fabricated and decorating the exterior with BBB‐targeting protein ligands (transferrin), thereby realizing enhanced drug retention and controlled release within ischemic lesions for the synergistic treatment of IS. Through the receptor‐mediated transcellular pathway, the transferrin‐coated MOF nanoparticles achieved efficient transport across the BBB and targeted accumulation at the cerebral ischemic injury site of mice with middle cerebral artery occlusion/reperfusion (MCAO/R), wherein the nanocarrier exhibited catalytic activities of ROS decomposition into O2 and H2O2‐responsive rapamycin release. By its BBB‐targeting, antioxidative, anti‐inflammatory, and antiapoptotic properties, the MOF nanosystem addressed multiple pathological factors of IS and realized remarkable neuroprotective effects, leading to the substantial reduction of cerebral infarction volume and accelerated recovery of nerve functions in the MCAO/R mouse model. This MOF‐based nanomedicine provides valuable design principles for effective IS therapy with multi‐mechanism synergies.

AbstractOrganic photothermal materials have attracted extensive attention due to their designable molecular structure, tunable excited‐state properties, and excellent biocompatibility, however, the development of near‐infrared II (NIR‐II) absorbing organic photothermal materials with high photothermal conversion efficiency (PTCE) and molar extinction coefficient (ɛ) remains challenging. Herein, a novel “electron‐donor iteration” strategy is proposed to construct organic photothermal dendrimers (CR‐DPA‐T, CR‐(DPA)2‐T and CR‐(DPA)3‐T) with donor‐π‐acceptor‐π‐donor (D‐π‐A‐π‐D) features and diradical characteristics. Owing to the enhanced D–A effect and intramolecular motions, their absorption and photothermal capacity increase as the generation grows. Surprisingly, an excellent photothermal performance (ɛ1064 × PTCE1064) with a superb value of 2.85 × 104 in the NIR‐II region is achieved for CR‐(DPA)3‐T nanoparticles (CR‐(DPA)3‐T NPs) compared to most reported counterparts. Besides, CR‐(DPA)3‐T NPs exhibit superior antitumor efficacy by the synergistic effect of photothermal therapy (PTT) and immunotherapy, efficiently inhibiting the growth of both primary and distant tumors. To the best knowledge, organic photothermal dendrimer is for the first time reported, and a universal donor engineering strategy is offered to develop NIR‐II‐absorbing organic photothermal materials for photothermal immunotherapy.

Published: October 2024

AbstractPerovskite nanocrystals (PNCs) are promising luminescent materials for electronic color displays due to their high luminescence efficiency, widely‐tunable emission wavelengths, and narrow emission linewidth. Their application in emerging display technologies necessitates precise micron‐scale patterning while maintaining good optical performance. Although photolithography is a well‐established micro‐patterning technique in the industry, conventional processes are incompatible with PNCs as the use of polar solvents can damage the ionic PNCs, causing severe luminescence quenching. Here, we report the rational design and synthesis of a new bidentate photo‐crosslinkable ligand for the direct photo‐patterning of PNCs. Each ligand contains two photosensitive acrylate groups and two carboxylate groups, and is introduced to the PNCs via an entropy‐driven ligand exchange process. In a close‐packed thin film, the acrylate ligands photo‐polymerize and crosslink under ultraviolet light, rendering the PNCs insoluble in developing solvents. A high‐density crosslinked PNC film with an optical density of 1.1 is attained at 1.4 µm thickness, surpassing industry requirements on the absorption coefficient. Micron‐scale patterning is further demonstrated using direct laser writing, producing well‐defined 20 µm features. This study thus offers an effective and versatile approach for micro‐patterning PNCs, and may also be broadly applicable to other nanomaterial systems.

AbstractPhagocytosis of shed photoreceptor outer segments by the retinal pigment epithelium (RPE) is essential for retinal homeostasis. Dysregulation of the phagocytotic process is associated with irreversible retinal degenerative diseases. However, the molecular mechanisms underlying the phagocytic activity of RPE cells remain elusive. In an effort to uncover proteins orchestrating retinal function, the cylindromatosis (CYLD) deubiquitinase is identified as a critical regulator of photoreceptor outer segment phagocytosis. CYLD‐deficient mice exhibit abnormal retinal structure and function. Mechanistically, CYLD interacts with enkurin domain containing protein 1 (ENKD1) and deubiquitinates ENKD1 at lysine residues K141 and K242. Deubiquitinated ENKD1 interacts with Ezrin, a membrane‐cytoskeleton linker, and stimulates the microvillar localization of Ezrin, which is essential for the phagocytic activity of RPE cells. These findings thus reveal a crucial role for the CYLD‐ENKD1‐Ezrin axis in regulating retinal homeostasis and may have important implications for the prevention and treatment of retinal degenerative diseases.

AbstractMagnetostrictive materials are essential components in sensors, actuators, and energy‐storage devices due to their ability to convert mechanical stress into changes in magnetic properties and vice‐versa. However, their operation typically requires physical contact to apply stress or relies on magnetic field sources to control magnetic properties. This poses significant limitations to devices miniaturization and their integration into contactless technologies. This work reports on an approach that overcomes these limitations by using light to transfer mechanical stress to a magnetostrictive device, thereby achieving non‐contact and reversible opto‐mechanical control of its magnetic and electrical properties. The proposed solution combines a magnetostrictive Fe70Ga30 thin film with a photo‐responsive Liquid Crystalline Network (LCN). Magnetic properties are modulated by changing the light wavelength and illumination time. Remarkably, the stable shape change of the LCN induced by ultraviolet (UV) light leads to the retention of magnetic properties even after the light is switched off, resulting in a magnetic memory effect with an energy consumption advantage over the use of conventional magnetic field applicators. The memory effect is erased by visible light, which releases the mechanical stress in the photoresponsive layer. Therefore, this new composite material creates a fully reconfigurable magnetic system controlled by light.

AbstractAlthough the layer‐by‐layer (LBL) processing can usually achieve an optimal bulk‐heterojunction morphology for high‐performance Organic photovoltaics (OPVs), the unambiguous working principles governing the morphology evolution are still lacking. To address this issue, here the phase‐separation kinetics of LBL processing are comprehensively studied using in situ spectroscopies, which are very sensitive to the intermolecular interactions, e.g. the molecular packing and D:A phase‐separation. Upon casting the nonfullerene acceptor (i.e., the BTP‐eC9) solution on top of the polymer donor, i.e., PM6, it is found that 1) the solvent will first swell the polymer and induce a polymer gel, 2) following the polymer gelation, the NFAs will immediately permeate into the cavities of polymer gel and form a molecular‐level D:A mixing, and 3) with the evaporation of the solvent, phase‐separation between the donor and acceptor occurs and results in a bulk‐heterojunction morphology as those achieved with blend‐cast processing. With these understandings, more diverse processing conditions have been purposely utilized to dictate the phase evolution process precisely. As a result, a high efficiency of 19.7% is reached, representing one of the best among binary OPVs. Therefore, this work deciphers phase‐separation kinetics of LBL processing and should pave the way toward advanced morphology control for high‐performance OPVs.
