Published: September 2019

Bacterial resistence is one of the global problems both in developed countries and devoloping countries. The high cases of resistence to antibiotics require the discovery of new active substances such as antibiotics agents. Therefore, to prevent the occurence of bacterial resistance to antibacterials need to be developed research in the disovery of new drugs derived from nature one of them is propolis. Propolis is a substance produced by bees to protect the nest from variety of threats, either unfavorable environmental threats or other organism attacks. One of type of bee that produces propolis is Trigona bee ( Trigona spp). The type of chemical compounds contained in propolis are very complex, among others alkaloid, flavonoid, steroid, saponin and tannin. This research is laboratory experimental study that aim to determine the antibacterial activity of ethanol extract of Trigona spp bee propolis against Propionibacterium acnes by disc diffusion methode. The concentration of ethanol extract of propolis used was 10 %, 20%, 30 %, 40 % with positif positive using clindamycin. From the result of the research, the inhibitory power of of ethanol extract of Trigona spp bee propolis with concentration 10 %, 20 %, 30 % dan 40 % is 11,7 mm, 12,3 mm, 13,6 mm and 14, 3 mm.

Authors: Amarnath Surath , Reddy Mettu Rami , Rao Chayam Hanumantha , Surath Harsha Vardan 
Published: September 2019

ABSTRACT
Background: Negative pressure wound therapy (NPWT) is an established modality in the treatment of chronic wounds, open fractures, and post-operative wound problems. This method has not been widely used due to the high cost of equipment and consumables. This study demonstrates an indigenously developed apparatus which gives comparable results at a fraction of the cost. Readily available materials are used for the air-tight dressing. Materials and Methods: Equipment consists of suction apparatus with adjustable pressure valve set to a pressure 125-150 mmHg. An electronic timer switch with a sequential working time of 5 min and a standby time of 3 min provides the required intermittent negative pressure. Readily available materials such as polyvinyl alcohol sponge, suction drains and steridrapes were used to provide an air tight wound cover. Results: A total of 90 cases underwent 262 NPWT applications from 2009 to 2014. This series, comprised of 30 open fractures, 21 post-operative and 39 chronic wounds. The wound healing rate in our study was comparable to other published studies using NPWT. Conclusion: The addition of electronic timer switch will convert a suction apparatus into NPWT machine, and the results are equally effective compared to more expensive counter parts. The use of indigenous dressing materials reduces the cost significantly.

Published: September 2019

Background & objectives:
Prokinetics are extensively prescribed leading to several adverse events (AEs). The aim of this study was to assess the prescription pattern in patients receiving prokinetics, and characteristics of adverse drug reactions (ADRs) in an outpatient department set up in a tertiary care hospital in western India.

Methods:
Patients attending outpatient departments of a tertiary care hospital and who had received prokinetic agent for at least seven days over the last one month were enrolled. Causality assessment of AEs was done and assessed for severity, preventability, seriousness and predictability.

Results:
A total of 304 patients [161 males (52.96%); 143 females (47.04%)] were enrolled. Most prescriptions (299/304, 98%) included domperidone, most commonly prescribed as fixed-dose combination (FDC) with pantoprazole (274/304, 90%). Prokinetic dose was not mentioned in 251/304 (83%) prescriptions, and 18/304 (6%) did not mention frequency. Of the 378 AEs reported from 179 patients (47.35%), 306 (81%) were mild, all non-serious; 272 (72%) not preventable and 291 (77%) predictable in nature. Decreased appetite (n=31, 8.2%) and fatigue (n=27,7.14%) were most commonly reported. Causality assessment by the World Health Organization-Uppsala Monitoring Centre scale showed that 180 AEs were related to suspected drug (17 probable and 163 possible ADRs). Significant correlation was observed for AEs with increasing number of drugs per prescription (Spearman's R=+0.8, P=0.05) and with increasing therapy duration (Spearman's R=+1.00, P<0.001).

Interpretation & conclusions:
Our findings showed that prokinetics were often prescribed as FDCs, with incomplete prescriptions. Domperidone was found to be associated with multiple AEs. It is suggested that regular prescription monitoring should be done in hospitals to encourage rational use of drugs.
The Twenty-First Century Revolutions and Internationalism: A World-Historical Perspective
Authors: Karataşli Şahan Savaş 
Published: September 2019

In his essay, “It is imperative to reconstruct the Internationale of workers and peoples”, Samir Amin (2018) suggested that in order to “deconstruct the extreme centralization of wealth and the power that is associated with the [capitalist world] system”, we should seriously study “the experience of the worker Internationales [...], even if they belong to the past. This should be done, not in order to ‘choose’ a model among them, but to invent the most suitable form for contemporary conditions.” In this paper, I will follow Amin’s (2018) suggestion and provide a brief examination of the past experiences of first Internationales in the nineteenth century and conditions that produced them with an eye to the present moment. By comparing the political climate of the early twenty-first century to analogous comparable periods in world history, I will argue that today we need two distinct forms of global political organizations that are modeled after the International Workingmen’s Association and the Communist League. First one should serve as a horizontal “movement of movements” that would reflect the spontaneous and creative energy of mass movements from below; the second one should serve as a hierarchically organized world communist party.
Space, Environment, and Appropriation: Sport and Settler Colonialism in Mi’kma’ki
Authors: Reid John 
Published: September 2019

AbstractThe displacement of Indigenous populations by settler societies forming within the British Empire was a global development during the eighteenth and nineteenth centuries, one in which settler sport took a significant role. Settler colonialism must be understood as a spatial and environmental phenomenon as well as a social and political one. This essay focuses on one geographical area: Mi’kma’ki, the homeland of the Mi’kmaq, corresponding to a substantial proportion of what is known in non-Indigenous terms as Canada’s Maritime region. It reflects on the direct and indirect appropriation of unceded Indigenous space for sporting purposes, along with the implications for Indigenous sport and the nature of Indigenous response to settler encroachment. Sport as an important element of social and cultural history has strong explanatory power in showing how settler colonialism and Indigenous persistence became entangled.
Decolonizing Dialogues: Sport, Resistance, and Australian Aboriginal Settlements
Authors: Osmond Gary 
Published: September 2019

Abstract
This paper seeks to extend understandings of Australian Aboriginal sport history by arguing that sport constituted a site of resistance for Aboriginal athletes in controlled settlements. While examples of overt resistance are rare, opportunities for covert, everyday resistance abounded. For activities performed beyond the notice of settlement administrators provided safe spaces for identity assertion and for expression of anger, dissatisfaction, grievance, unhappiness, or other sense of injustice. Sport, although publicly performed, was a potential site for acts of everyday resistance. This paper explores resistance through oppositional acts of stealing, drinking, and playing-to-rule, which are explored through “hidden transcripts. “ Research for this paper focuses on Queensland, a state with a uniquely odious record on Aboriginal affairs. By focusing on sport as a site of resistance, it offers new insight into the sociocultural practice and meanings of sport in Aboriginal communities historically and, more broadly, on decolonizing sport history.
Runaways, Dutiful Daughters, and Brides: Family Strategies of Formerly Enslaved Girls in Senegal, 1895–1911
Authors: Bryant Kelly M. Duke 
Published: September 2019

Abstract
This article explores how formerly enslaved girls in Senegal interacted with, challenged, rejected, and formed families in the early twentieth century. Relying on records pertaining to the system of guardianship, which supervised these so-called liberated minors following the French emancipation decree of 1848, the article shows how marginalized girls used a variety of strategies to pursue their familial goals, sometimes turning state structures to their advantage. It argues that girls’ efforts to establish family-like relationships with guardians or others, to take up residence with sexual partners, to marry, and to have children must be read as steps toward reclaiming personhood and rejecting slavery.
When Social Media Yields More than “Likes”: Black Girls’ Digital Kinship Formations
Authors: Wade Ashleigh 
Published: September 2019

Abstract
This article explores the tenets of Black girls’ digital kinship by detailing an ethnographic study in which I developed and taught an elective course for a group of Black high school girls. I use my participant-observation from a five-month period teaching these students in order to argue that there is mutual mediation between kinship and digital production. I define digital kinship as a relational practice through which familial ties—with both origin family and chosen family— are established and/or maintained through digital technologies. Contextualizing my definition of digital kinship within the literatures of Black American family structures and digital community-building, I show how Black girls’ offline familial ties appear in and/or influence their content on digital platforms such as Facebook and Snapchat along with what kinds of factors lead to the establishment of kin relationships within digital spaces specifically. Ultimately, I analyze the digital kinships formed by the girls in my class to conclude that digital spaces create more possibilities for Black girls to form support networks and exercise an agency to control space often denied them in their everyday school and home environments.

Published: September 2019

Maximum production potential of leafy vegetable is limited by phosphorous (P) deficiency in the soils. This is due to the high cost of the phosphate fertilizer and the fixed form of the available phosphorous in the soil. There is therefore, need for farmers to use alternative and cheaper sources of P that are economic friendly to supply the required mineral nutrition to their crops. Rock phosphate is widely available but has a challenge in solubilization to make P available to the crops. In the current study, the aim was to evaluate the effect phosphate forms and acidulate rock phosphate on growth and yield of selected leafy vegetables. The experiment was laid out in Randomized Complete Block Design in split-plot arrangement, with three leafy vegetables (cowpeas, kales and amaranth) being the main plots, and various sources of P (Triple super phosphate (TSP) Mijingu Phosphate Rock(MPR), Mijingu phosphate Rock + sulphur (MPR)PR+S and control) constituting the subplots with three replicates. The collected data included: root dry weight, leaf area, shoot fresh weight and leaf area and was subjected to SAS for ANOVA and where there were significant differences between means were further separated using the Fischer’s LSD at 5% level of significance. The results revealed that there were significant increase in the growth parameters of the vegetables as an effects of phosphorus application compared with the control. TSP elicited the best results in all the tested parameters in 5 WAP, 6 WAP and 7 WAP respectively in both seasons The highest value of root dry weight (11.2 g), leaf area (1905.0 cm2), number of branches (40.67) shoot fresh weight (236.8 g) as influenced by TSP application in the vegetable species. The MRP + sulphur also followed in superiority of increasing the growth parameters which is an indication that sulphur can be used in solubilizing rock phosphate and making it a suit alternative for farmers. Thus, farmers are advised to directly apply rock phosphate and sulphur to soil as a possible alternative to the more expensive soluble phosphate fertilizers in tropical cropping system.

ObjectiveDifferent classification criteria for systemic lupus erythematosus (SLE) have been proposed for many years. The most widely used and accepted criteria has been the 1997 American College of Rheumatology (ACR) criteria. In 2012, the Systemic Lupus International Collaborating Clinics (SLICC) criteria were published in an attempt to improve the clinical relevance of SLE criteria. In 2017, weighted criteria were proposed that included entry criteria, something the 1997 ACR and the 2012 SLICC criteria did not identify. The aim of the present study was to validate the 2017 weighted criteria, the 1997 ACR criteria, and the 2012 SLICC criteria and compare the sensitivities and specificities in pediatric SLE.MethodsFor the past 15 years, retrospective chart review of patients diagnosed with SLE before age 19 years was conducted. The controls were patients referred for serologies positive for antinuclear antibodies but did not fulfill criteria for diagnosis of SLE at the initial visit or were diagnosed with another autoimmune disease. The 3 classification criteria sets were applied to these patients and compared against a gold standard of physician diagnosis.ResultsA total of 156 patients were diagnosed with SLE. The sensitivity for the 2017 weighted criteria was 0.974 (95% confidence interval [95% CI] 0.936–0.993) and the specificity was 0.984 (95% CI 0.966–0.994). The sensitivity for the 1997 ACR criteria was 0.872 (95% CI 0.809–0.920) and the specificity was 1.00 (95% CI 0.990–1.000). The sensitivity for the 2012 SLICC criteria was 0.974 (95% CI 0.936–0.993) and the specificity was 0.997 (95% CI 0.985–1.000).ConclusionThe 2017 weighted criteria and the 2012 SLICC criteria were more sensitive than the 1997 ACR criteria. There were no significant differences in sensitivity and specificity between the 2012 SLICC and the 2017 weighted criteria.

AbstractSelective manipulation of specific single cells for therapeutics is important and highly desirable in biomedical research. As a simple and maneuverable tool, tubular micromotors have displayed appealing applications in encapsulation and transportation of cells. However, so far there are no reports on the simultaneous transportation of target single cells and the drugs with microtubes in a custom arrayed environment for targeted therapeutics. Moreover, fabrication of microtubes with 3D features in a reproducible and single‐step fashion, while, endowing them with the ability of remote control, remains challenging. In this study, a novel method for one‐step fabrication of magnetic 3D tubular micromotors by single exposure of structured optical vortices in a magnetic photoresist is presented. The size and geometry of fabricated microtubes are flexibly controlled in three dimensions. Precise propelling of the tubular micromotors and precise capture, targeted delivery, and release of SiO2 microparticles are realized. Finally, as a proof‐of‐concept demonstration, in situ observation of the development of doxorubicin in Hela cells for therapeutic study is performed by targeted delivery of single cells and drug particles. The technology is simple and stable, which has promising applications in targeted cell therapy, drug screening, single cell studies, and other biomedical areas.
The Reliability of the Density‐Functional Theory in Actinide Endohedral Systems

Published: September 2019

AbstractDensity‐functional theory (DFT) has shown obvious violation to the Jacob's ladder in predicting the geometric and electronic structures of carbon‐based high‐Z elements endohedral metallofullerenes (hZ‐EMFs). This has aroused long‐term discussion in both theoretical and experimental fields, because this is related to whether the computationally efficient DFT can be the substitution to post‐HF. In this work, the violation to the Jacob's ladder emerges again on the boron based uranium endohedral structure U@B40. The proper choice of functionals has been a significant factor to predict both geometric and electronic structures of U@B40. Pure generalized gradient approximations (GGA) functionals give a high symmetrical singlet ground state of D2d, while a slightly tortured C2v triplet state is more stable when hybrid GGAs are used. Compared to pure GGAs triplet state, the spin density accumulates more obviously on its B40 cage in hybrid GGAs triplet state. The qualitative difference originates in the proportion of exact exchange energy that can exert a tremendous influence on energy splitting between electronic states of U@B40. This controversial calculation is an ideal model to reestimate the role of exchange functionals in studying hZ‐EMFs. Therefore, these findings will provide important references to the benchmark experiments and future theoretical predictions.

AbstractAll‐solid‐state lithium metal batteries (ASSLMBs) stand out for the next generation of energy storage system. However, the further realization is severely hampered by the lithium dendrite formation in solid state electrolytes (SSEs), by mechanisms that remain controversial. Herein, with the aid of experimental and theoretical approaches, the origin of dendrite formation in representative LiBH4 SSE, which is thermodynamically stable with the Li metal, suppressing the side reaction between Li and SSE is elucidated. It is demonstrated that upon diffusion, Li+ encounters an electron, and is subsequently reduced to Li0 within the grain boundary/pore of SSE, eventually leading to short circuit. Thus, introducing LiF with the ability of interstitial filling and low electronic conductivity into SSE is the effective countermeasure, and as expected, with the addition of LiF, the critical current density (CCD) increases by 235% compared to the value of pure LiBH4. The TiS2|LiBH4–LiF|Li ASSLMBs manifest a reversible capacity of 137 mAh g−1 at 0.4 C upon 60 cycles. These findings not only unravel critical issues in Li dendrite formation in SSE, but also propose the countermeasure.

Published: September 2019

Cu‐doped Ni‐based metal–organic frameworks (MOFs) nanomaterials fabricated through a one‐pot hydrothermal reaction were characterized, and their performance as supercapacitor electrode materials was further studied for the first time. The results indicated that the doping of foreign metals and the introduction of K3[Fe(CN)6] in the KOH electrolyte significantly improve the performance of the supercapacitor. The results indicated that the Ni2.6Cu0.4 MOFs material shows the highest specific capacitance (1282 F g−1 at 1 A g−1 in mixed 2 M KOH and 0.1 M K3[Fe(CN)6]) and optimal capacitance retention (85.7% after 2000 cycles). This work provides a feasible optimization strategy for the construction of MOFs‐based supercapacitor electrode materials with excellent performance, and also provides a reliable experimental and theoretical basis for practical industrial production.
