Transfeminismo y activismos queer: emergencia y cohabitación en las fronteras de la coalición
Authors: Pérez Navarro Pablo 
Published: October 2019

El ciclo de protestas que se abrió en las primaveras árabes ha servido para revitalizar la reflexión teórica sobre el modo en que los procesos de agenciamiento político son indisociables de los modos de producción de los espacios de coalición. Es el caso de Judith Butler en Cuerpos aliados y lucha política, junto con otras autoras que han mostrado la importancia de pensar los modos de encuentro corporal, y las políticas de acceso a los espacios de aparición, como parte central de la lucha y la reflexión política. En diálogo con estas y otras provocaciones teóricas, fundamentalmente en el ámbito de los estudios queer, este ensayo explora los modos de producción del espacio de coalición transfeminista y queer a partir de experiencias activistas recientes en la ciudad de Madrid.The cycle of protests opened by the Arab Springs has served to revitalize theoretical reflections on the interplay between the construction of political agency and the production of coalitional spaces. This is the case of Judith Butler in Bodies in Alliance and the Politics of the Street, along with other authors that have shown the importance of thinking bodily encounter, and the politics of accessibility to the space of appearance, as a central part of political reflection and struggle. In dialogue with these and other theoretical provocations, specially coming from Queer Studies, this essay explores the modes of production of the space of transfeminist and queer coalition drawing on recent activist experiences in the city of Madrid.
Personal data are political. A feminist view on privacy and big data
Authors: Suárez-Gonzalo Sara 
Published: October 2019

The second-wave feminist critique of privacy defies the liberal opposition between the public-political and the private-personal. Feminist thinkers such as Hanisch, Young or Fraser note that, according to this liberal conception, public institutions often keep asymmetric power relations between private agents away from political discussion and action. The resulting subordination of some agents to others tends, therefore, to be naturalised and redefined as a «personal problem». Drawing on these contributions, this article reviews the social and political implications of big data exploitation and questions whether personal data protection must remain a matter of «privacy self-management». It aims to show that feminist political theory can decidedly help to identify and tackle the root causes of what I call «data domination».La crítica feminista de segunda ola a la privacidad desafía la oposición liberal entre lo público-político y lo privado-personal. Pensadoras feministas como Hanisch, Young o Fraser señalan que, de acuerdo con esta concepción liberal, las instituciones públicas a menudo dejan fuera de la discusión y la acción política las relaciones de poder asimétricas entre agentes privados. La resultante subordinación de unos agentes a otros tiende, por tanto, a ser naturalizada y redefinida como un «problema personal». Basándose en estas contribuciones, este artículo revisa las implicaciones sociales y políticas de la explotación de datos masivos y cuestiona si la protección de los datos personales debe continuar siendo una cuestión de «auto-gestión de la privacidad». Su objetivo es mostrar que la teoría política feminista puede ayudar decididamente a identificar y enfrentar las causas de lo que llamo «dominación a través de los datos».

Development of a Training Program for Family Caregivers on Home Care of Older Adults in Cameroon
Authors: Ubenoh Ukum Susan , Bassah Nahyeni , Palle John Ngunde 
Published: October 2019

Background: Family caregivers who are the primary care providers to the elderly in communities in Cameroon, specifically in the Buea health district, are not aware of available resources and lack adequate knowledge and skills on the care of the elderly. As a result, the elderly are not receiving adequate care and support which might also affect their quality of life. In line with the World Health Organization’s (WHO) strategic proposed objectives of promoting healthy aging, the aim of this study was to develop a training program for family caregivers of the elderly.
Methods: An exploratory, cross-sectional study research design was employed, with the use of qualitative methods for data collection. In-depth interviews were conducted with 15 key informants including nurses, social workers, community relay persons, personnel from the ministries (Public Health and Social Affairs), director of a geriatric nurse training school and directors of Non-Governmental Organizations (NGOs) concerned with age-care who were purposively recruited. Information on the scope of practice and available resources was obtained. The sample size was determined based on data saturation. Data was transcribed verbatim and analysed using thematic content analysis.
Results: Two major themes emerged from data analysis; ‘Recognise the boundary’ for the scope of practice of family caregivers which was further divided into two categories (bridge the gap and shared responsibilities)’ and ‘Health and wellbeing’ as all available resources were aimed at improving the health and wellbeing of the elderly.
Conclusion: The training program should include a pyscho-educational intervention with information on available resources such as: Geriatric nurses and social centers, the scope of practice for family caregivers which includes: Assistance with Activities of Daily Living & Instrumental Activities of Daily Living, Psychosocial care, strategies to involve elderly persons in various activities and the creation of age- friendly environments.

Authors: O. Olusola-Makinde O. , J. Arotupin D. , C. Adetuyi F. 
Published: October 2019

Aims: This study examined the prevalence of filamentous fungi in Onyearugbulem abattoir wastewater samples in Akure, Nigeria.
Methodology: The abattoir’s water source, 5 m away from animal washings, the incinerator, 10 m upstream, 10 m downstream and 100 m downstream were sampled between November 2014 and October 2015 for aerobic and anaerobic fungal counts using standard recommended procedures. Fungal isolates were identified macroscopically and microscopically.
Results: The results showed that the water source had the lowest fungal count (1.4x103 sfu/ml in November and 2.0x102 sfu/ml in February for aerobic and anaerobic counts respectively) throughout the sampling period unlike the incinerator which had the highest fungal count (5.2x103 sfu/ml in August and 5.5x103 sfu/ml in July for aerobic and anaerobic counts respectively). The aerobic fungal count was lower than the anaerobic fungal count in all the six (6) sampling points except the abattoir water source. The trendline of the data collected also showed a significant increase (p≤0.05) of the fungal counts in the wet season as compared to the dry season. The fungi isolated are Rhizopus spp., Aspergillus fumigatus, Penicillium chrysogenum, Fusarium oxysporium and Saccharomyces cerevisiae.
Conclusion: This work indicated a high dominance of fungi in water bodies associated with the slaughterhouse and therefore warns against environmental and health hazards associated with these microorganisms.

Authors: Elnour Rahma Mohamed Salma , Alobied Alfadil , Ibrahim Saeed Mohamed , Mohamed Hussien Wafa 
Published: October 2019

Carbapenem resistance mediated by NDM is particularly gruesome as this carbapenemase can hydrolyze a wide range of β-lactam antibiotics.
Aim: This study aims to detect NDM mediated carbapenem resistance in clinical isolates of Pseudomonas aeruginosa.
Materials and Methods: 50 multi-drug resistant clinical urinary isolates of Pseudomonas aeruginosa from three major hospitals in Khartoum state Sudan; Khartoum Teaching Hospital, Medical Army Hospital and Omdurman teaching hospital, in period from July 2016 to September 2017, were investigated for carbapenem resistance using standard disc diffusion method and underwent real-time PCR to detect carbapenem resistance gene blaNDM. Data were analyzed using IBM SPSS.
Results: 60% were positive for the blaNDM, 82% were resistant to Imipenem and 75% of the samples were resistant to Meropenem.
Conclusion: The emergence of carbapenem resistance is a global problem that requires earnest attention. To make the suitable preventive measures, the emergence of these genes must be monitored closely. Our findings revealed that carbapenem-resistant due to the gene blaNDM is accounted for 60% of the cases, and due to lack of proper data documentation about the emergence of this gene in Sudan, these cases to the best of our knowledge are the first to be reported in Sudan.

Authors: M. Adeyemo O. , A. Onilude A. 
Published: October 2019

Aims: The aims of this study were to screen for potential broad-spectrum antimicrobial-producing actinomycetes from the tropical rain forest of Oyo State, Nigeria, to assess the effects of cultural conditions on antimicrobial metabolites, characterize the metabolites and determine its antimicrobial activity against indicator strains.
Place and Duration of the Study: Department of Microbiology, University of Ibadan, Ibadan, between April 2014 and August 2016.
Methodology: Ten soil samples were purposively collected between April and June 2014 for the isolation of Actinomycetes. The isolated strain was identified culturally and molecularly using 16S rDNA. The effect of cultural parameters on antimicrobial activity was done by a standard method. The antimicrobial metabolites were produced by submerged fermentation. Partial purification was carried out by column chromatography. Chemical characteristics of the metabolites were determined by Fourier transformed infra-red spectrometer (FTIR) and gas chromatography coupled with a mass spectrometer. The antimicrobial activity was done by agar well diffusion and macro broth dilution.
Results: Isolate OY62 had broad-spectrum antimicrobial activity and it was identified using its 16S rDNA gene as Streptomyces xinghaiensis-OY62 (KU934248). The highest antimicrobial activity against indicator strains was recorded between pH 7 and pH 8, 0.8% (w/v) sodium chloride, at elevated temperature 55°C, casein+KNO3 as a nitrogen source, starch or absence of carbon source and incubation period of fifteen days. Aliphatic alkene, hydroxyl, carboxylic acids, amides and carbonyls were functional groups detected while thirteen antimicrobial metabolites were characterized. The MIC against indicator strains was between 6.25 mg/L to 12.5 mg/L. Streptomyces xinghaiensis-OY62 exhibited broad-spectrum activity against indicator strains.
Conclusion: The observed results showed that potential broad-spectrum antimicrobial-producing strains of Streptomyces could be isolated from the soil of southwestern Nigeria, which could be useful in the production of antimicrobials that can inhibit the growth of resistant pathogens, reduce microbial infections and death.

Published: October 2019

Aims: Production of gellan gum by Sphingomoas paucimobilis from whey was optimized by different fermentation techniques.
Study Design: Study the growth behavior of Sphingomoas paucimobilis was cultivated on 40% sweet whey medium in the bioreactor as a batch, fed batch and continuous culture and effect of aeration and agitation speed on gellan production.
Place and Duration of Study: Microbiology Dept., Fac. of Agriculture, Ain Shams Univ., Cairo, Egypt, 2016/ 2017.
Methodology: Using Sphingomoas paucimobilis on sweet whey in the bioreactor as a batch, fed batch (pulsed & continuous) and continuous culture. Among the four levels of air saturation and four levels of agitation speeds.
Results: Using the continuous feeding of sugar sweet whey at 1.53 gl-1h-1during 12 h was favorable than pulsed feeding for gellan production in fed-batch culture. In continuous culture addition of 40% SW at 0.055 h-1 dilution rate (110 ml h-1), the values of gellan parameters recorded by Sphingomoas paucimobilis were 24.34%, 26.54% & 0.337 gl-1h-1 for gellan yield, conversion coefficient and gellan productivity during 24 h. At 28ºC. This technique increments the gellan production (gl-1h-1) by 3.3 & 2.2-2.5 and 1.5- 1.6 fold as compared to that produced by using batch & fed- batch pulsed and fed-batch continuous techniques respectively. The emulsifying capability of the partially purified gellan was 100% whereas it was 95% for xanthan gum, as well as its high flocculating activity than xanthan. A tough worm-like gel or firm gel were formed when 10% calcium chloride solution or 0.5 g sodium chloride were added to gellan solution.
Conclusion: The maximum gellan yield and lower fermentation period were obtained with air saturation of 60% at 750 rpm agitation speed. The continuous feeding at 1.53 gl-1h-1 was favorable than pulsed feeding for gellan production in fed-batch culture, while the maximum gellan productivity was obtained by using a continuous culture technique at 0.055 h-1 dilution rate.

Published: October 2019

Aims: Currently there is a high demand on novel anti-microbial agents derived from natural sources due to low cost and less adverse effects. The present study was designed to screen the anti-microbial activity of different extracts of Oldenlandia auricularia against common pathogenic bacteria and fungi.
Study Design: Experimental study.
Place and Duration of Study: Department of Basic Sciences at Faculty of Allied Health Sciences and Research Laboratory at Faculty of Medicine, General Sir John Kotelawala Defence University, Ratmalana, Sri Lanka, between July 2018 and November 2018.
Methodology: The aqueous, methanol, acetone and hexane extracts were prepared with the leaves, roots and stem of the plant Oldenlandia auricularia separately. The agar well diffusion method and broth macro dilution method were applied in order to screen the anti -microbial activity of each test extract against the Escherichia coli, Salmonella enterica, Shigella dysenteriae, Candida albicans and Staphylococcus aureus.
Results: The zone of inhibition of most of the test extracts showed a significant (P =.05) difference, when compared with the negative control. The lowest MIC value for test extracts was 31.25 mg/ml, while the highest was 250 mg/ml. The acetone extract of the stem showed the lowest MIC value against E. coil. The highest anti-bacterial activity against S. enterica exerted by the root of the plant. All three tested parts of the plant were active against S. aureus and the maximum activity against C. albicans was shown by the leave extracts. The lowest MIC value against S. dysenteriae was 62.5 mg/ml, which indicated that the plants materials are less sensitive to the S. dysenteriae than the other tested pathogens. The results of the quantitative assay confirmed the results obtained from the qualitative assay.
Conclusion: The different parts of Oldenlandia auricularia plant displayed potential antimicrobial activity against different pathogens.

A study on the antibacterial activities of Bryophylum pinnatum against multidrug resistant bacterial pathogens was carried out in this research. Air-dried and powered Bryophylum pinnatum leaves was extracted using ethanol and aqueous solvents. Five bacteria strains including Staphylococcus aureus, Streptococcus pneumoniae, Bacillus subtilis, Escherichia coli and Pseudomonas aeruginosa were obtained from the University of Benin Teaching Hospital and they were preliminarily identified using standard microbiological methods. Antibacterial activity was carried out using agar well diffusion method. Mean zone diameter of inhibition in aqueous extract ranged from 9.20±0.17-10.50±0.50mm and 9.30±0.33- 10.33±0.89mm against Escherichia coli and Staphylococcus aureus respectively at 25-100mg/ml. In the ethanol extract, mean zone of inhibition ranged from 9.50±0.28-13.33±0.88mm and 10.67±0.67-19.00±0.58mm at concentration range of 6.25-100mg/ml. Minimum inhibitory concentrations of ethanol extract ranged from 6.25-100 mg/ml against bacterial strains. While those of aqueous extract ranged from 25-100 mg/ml against bacterial isolates. Minimum bactericidal/fungicidal concentrations of ethanol extract ranged from 25-50 mg/ml. While in the aqueous extract, value was 50 mg/ml and against bacteria. The test bacterial pathogens were found to possess multiple drug resistance potential with multidrug resistance index ranging from 0.3 – 0.5. This study has shown that multidrug resistant clinical bacterial pathogens are sensitive to aqueous extract of Bryophyllum pinatum.
