Neither prelegal nor nonlegal: Oral memory in troubled times
Authors: Ngoepe Mpho
Published: June 2022

Oral testimony, oral tradition and documents, as represented by written accounts of the facts and the material instruments of the acts and the records, are all ways of indirectly accessing the past. In both cases of oral and written records, what is considered ‘true’ is entirely dependent on the trustworthiness of its source. African societies have been communicating and storing valuable information through memory, murals and rock art paintings since time immemorial. The dominant Western canons have previously classified this memory as prelegal and nonlegal. This study, using a literature review, mainly through previous work of this author, explores oral memory as a trusted record in troubled times. It is concluded that, like digital records, oral memory requires proactive efforts to be preserved, as in both instances the content migrates from one carrier to another. Therefore, oral memory is trustworthy when transmitted in its context. Oral memory, it is argued, perfectly fits the description of a record and thus cannot be classified as either prelegal or nonlegal. The transmitter of information through oral history is no different from other media of records.Contribution: The study contributes to the ongoing academic discourse of decolonising and Africanising archives. The study is linked to the scope of the journal for advocating the inclusion of silenced voices into the national archival system.
Pathology and pain, disease and disability: The burdens of the body in the Book of Job peering through a psychoanalytic prism
Authors: Van der Zwan Pieter
Published: June 2022

Not only trauma, mourning and disease, but also disability has been recognised in the Book of Job in which the body plays an exceptional role. The protagonist is suffering physically, psychically and spiritually. Although the word, חלה [be sick, ill], never occurs in the book, his body is portrayed negatively being afflicted by some unknown illness, which would probably exclude him from the community described in Leviticus 13–14. While חָרֵשׁ [be silent] occurs several times in the book, it never has the alternative meaning of deaf. Yet, his explicit empathy and sacrificial charity לַעִוֵּר [for the blind] and לַפִּסֵּחַ [for the lame] in 29:15 resonate with his own plight and undermine the possible discriminatory restrictions of like disabled in Leviticus 21:18. In this way, the Book of Job has a transgressive and yet liberating subtext, subverting the idealised body of his status quo. This subtle and veiled critique by the protagonist and therefore the book can be interpreted from a psychoanalytic perspective on physical disability and illness, where the symptoms and alleged imperfections of the body quietly cry out against social and cultural injustice of which they are the projections and mirrors when the context has silenced a concern for the body because of a lack of compassion as it is in the situation of Job.Contribution: The intersection and cross-fertilisation of Biblical Studies, Disability Studies and psychoanalytic theory as interdisciplinary approach widens the horizons and deepens the insight of all three research fields, hopefully for the benefit of those who suffer from their bodies, their psyches and their societies.
Eenheid en gelykheid uitgedruk deur die metafoor van die wapenrusting in Efesiers 6:10-18
Authors: Vrey Alta
Published: June 2022

The Holy Spirit and the Word of God are gifts to the whole church. Every believer in Jesus Christ is part of the body of Christ, the temple of God, the household of the Father and the army of the Spirit. One of the main themes of the letter to the Ephesians is unification in Christ between Jews and Gentiles. The author concludes his letter in Ephesians 6:10 with the metaphor of the armour of God: ‘In conclusion, be strong in the Lord [be empowered through your union with Him] and in the power of His might.’ (AMP). Our union with Christ, which should be reflected in our union with other believers, empower us to be strong in our fight against evil in this world. Unification cannot be complete if the value of each member is not acknowledged. Though roles may differ, the value of each member is measured by the price that Christ paid on the cross for our redemption. Equality unite; inequality divide. Equality for all members of Christ’s church is essential in the fight against evil powers like domination and inequality.The writer of Ephesians uses metaphors to convey the message of unification and equality, especially between Jews and Gentiles, in the newly formed first century church. Unfortunately the position of slaves, woman and children in the church are still subject to cultural norms and values of the time.The message of this letter should be filtered through the lens of patriarchy in the first century Mediterranean world. According to Osiek the whole Mediterranean society was patriarchal (2006:832). The metaphor of the Roman soldier’s armour is a male image used to describe a spiritual war in which all believers are involved. The equality in today’s society should not be limited by cultural first century boundaries, in Ephesians the fight against evil should be an example of the unification and equality of gender, ethnicity, social status and age groups.ContributionThe metaphor of the armour of God describe the spiritual fight against evil powers and although the image of a male Roman soldier is used, the fight is not limited to male members of the church. Every believer is valuable enough that Christ died for him/her and therefore every believer should be equal in the army of God. The empowering strength of the Holy Spirit should bring equality and unity in the church.

Published: June 2022

This article seeks to explore the role of higher education institutions (HEIs) in climate change adaptation and disaster risk management (DRM). The study is based on the qualitative desk review, thematic and document analysis and uses the theory of change to facilitate a road map for HEIs in strengthening professional human development, policy consistency in dealing with climate-induced natural disasters (CINDs) research and policies. Academic journals covering the role of HEIs in climate and disaster management in Zimbabwe were selected on google scholar. Reviewed documents include universities’ curriculum documents, government disaster policy documents and other related disaster management policy protocols. The article’s findings reflect that HEIs in Zimbabwe have been engaged in climate change education and DRM as the country and the region are prone to threats posed by extreme weather events in the form of tropical cyclones and extreme droughts. The article concludes that HEIs core mission that includes public engagement to advance achieving sustainable development goals in Zimbabwe is growing at a steady pace to find ways to avert the impact of climate change and put strategies in place to respond to disaster to minimise social, environmental and economic losses posed by disasters. Bindura University of Science Education (BUSE) is enhancing people’s resilience in Chadereka village in Muzarabani through disaster preparedness training. National University of Science Technology (NUST) is also training communities on disaster concepts, disaster prevention, mitigation, preparedness and response.

Developing and prioritising strategies to improve the implementation of maternal healthcare guidelines in South Africa: The nominal group technique
Authors: Ramavhoya Thifhelimbilu I. , Maputle Maria S. , Lebese Tinyiko R.
Published: June 2022

Background: In South Africa, maternal healthcare guidelines are distributed to primary health care (PHC) facility for midwives to refer and implement during maternal healthcare services. Different training was offered for the use of maternal care guidelines. However, poor adherence and poor implementation of guidelines were discovered.Aim: This study aimed to develop and prioritise strategies to improve the implementation of maternal healthcare guidelines at PHC facilities of Limpopo province, South Africa.Method: Strengths, weaknesses, opportunities and threats analysis and its matrix together with the nominal group technique were used to develop the current strategy. Midwives, maternal, assistant and operational managers from PHC facilities of the two selected district of the Limpopo province were selected. Criterion-based purposive sampling was used to select participants. Data collection and analysis involved the four steps used in the nominal group technique.Results: Strategies related to strengths and weaknesses such as human resources, maternal health services and knowledge deficit were identified. Opportunities and threats such as availability of guidelines, community involvement and quality assurance as factors that influenced the provision of maternal healthcare services were identified.Conclusion: Researchers formulated actions that could build on identified strengths, overcome weaknesses such as human resources, explore opportunities and mitigate the threats such as quality assurance. Implementation of the developed strategies might lead to the reduction of the maternal mortality rate.
Digitally supported HIV self-testing increases facility-based HIV testing capacity in Ekurhuleni, South Africa
Authors: Mshweshwe-Pakela Nolundi T. , Mabuto Tonderai , Shankland Luke , Fischer Alex , Tsukudu Dikeledi , Hoffmann Christopher J.
Published: June 2022

Background: HIV testing is the first step for linkage to HIV prevention or treatment services. Facility-based HIV testing is the most utilised method, but faces challenges such as limited work space and human resources. Digitally supported HIV self-testing (HIVST) provided in clinics shifts testing to the client, potentially empowering the client, and addresses such constraints.Objectives: The study primary objective was to determine the feasibility of integrating digitally supported HIVST into the clinic. Secondary objectives were to describe HIV testing volume, populations reached, and antiretroviral treatment (ART) initiation.Method: We conducted an analysis of prospectively collected data during implementation of digitally supported HIVST in two healthcare facilities based in South Africa from June 2019 to September 2019. We described implementation and client characteristics using HIVST and compared testing before and during implementation.Results: During the 4-month implementation period there were 35 248 client visits. A total of 6997 (19.9%) of these visits involved HIV testing. Of those testing, 2278 (32.5%) used HIVST. Of the 2267 analysed, 264 (11.6%) were positive: 182 (12%) women and 82 (11%) men. Of those, 230 (95.4%) were confirmed HIV positive and 150 (65%) initiated ART within 14 days. During a four-month pre-implementation period, 14.5% of the clients tested for HIV. Compared to the pre-implementation period, we observed a 25% increase in HIV testing.Conclusion: Digitally supported HIVST increased the number of clients completing HIV testing in the health facility, without a need to significantly increase staff or space. Facility-based digitally assisted HIVST has the potential to increase HIV testing in high HIV prevalence clinic populations.
A diary study of the impression management strategies utilised by industrial and organisational psychology interns
Authors: McGowan Nasreen A. , Sekaja Lusanda
Published: June 2022

Orientation: When interns enter a new workplace, they are compelled to create and maintain a good impression through a range of image-enhancing behaviours. Impression management strategies can help interns to do this.Research purpose: This study aimed to understand the strategies used by industrial and organisational (I/O) psychology interns, their goals for using them and the targets of these strategies.Motivation for the study: Interns are generally new to the workplace and, as such, may not be aware of how to play the ‘social game’ to create positive impressions about themselves, be perceived in a positive light, gain projects to fulfil their internship requirements, and, where possible, gain full-time employment from the organisation.Research approach/design and method: A qualitative design was used. Data were collected from 14 I/O psychology interns in the form of diary entries and semi-structured interviews.Main findings: The thematic analysis revealed eight key impression management strategies, some existing and others novel: ingratiation, self-promotion, rendering favours, exemplification, professionalism, openness to learning, conformity and building strategic relationships.Practical/managerial implications: Industrial and organisational psychologists should develop workshops to assist interns in using impression management skills to create a positive internship experience and advance in their respective organisations.Contribution/value-add: The study adds theoretically (the study of impression management is relatively new in South Africa), practically (findings may help direct future I/O psychology interns to the correct strategies for creating a positive impression at work) and methodologically (diary studies are not common in qualitative organisational research).
Injury surveillance in community cricket: A new inning for South Africa
Authors: Olivier Benita , Obiora Oluchukwu L. , MacMillan Candice , Finch Caroline
Published: June 2022

Published injury rates amongst elite and club-level youth cricketers highlight the need to implement injury risk-reducing strategies amongst the youth cricketing population. Data from sports injury surveillance systems are a prerequisite for the development and evaluation of strategies to reduce injury risk. Therefore, collecting injury surveillance data is a positive move towards reducing injuries in cricket. In South Africa, a systematic, standardised, evidence-informed injury surveillance system currently does not exist for community levels of play, namely, in cricket-playing high schools and cricket clubs. Although injury surveillance systems exist at elite levels, the obvious differences in elite versus community cricket settings mean that these systems cannot be implemented in their current form at community-level cricket. An innovative model is required to implement an injury surveillance system in community cricket.Clinical implications: This article proposes and describes a new research–practice partnership model to implement a systematic, standardised, evidence-informed injury surveillance system at cricket-playing high schools or cricket clubs within South Africa. Once this model has been employed, database systems will need to be established to allow long-term data management and sharing.

Published: June 2022

This protocol describes a study in which we would assess the effect of using community lay counselors, self-help groups (SHGs), and trained frontline health workers to reduce mental disorders and improve quality of life (QOL) of persons affected by leprosy or Buruli ulcer (BU). A cluster randomized controlled study design will be employed. The study will involve persons affected by leprosy or BU. Ten local government areas (clusters) with the highest number of notified leprosy or BU cases between 2014 and 2018 in Southern Nigeria will be purposively selected. The clusters will be randomized into intervention and control groups using a computer-generated list of random numbers. At baseline, data were collected using the following validated questionnaires, Patient Health Questionnaire, Generalized Anxiety Disorder questionnaire, Stigma Assessment and Reduction of Impact Scale, World Health Organization QOL BREF and Warwick-Edinburgh Mental Well-being scale among persons affected by leprosy or BU. The intervention will last for 2 years and will involve use of community lay counselors, SHGs, and appropriately trained frontline health workers in reducing mental disorders and improving QOL of persons affected by leprosy or BU. This project postulates that the reduction of burden of mental health problems and improved QOL among persons affected by leprosy or BU could be achieved through a holistic approach involving SHGs, appropriately trained community opinion leaders, and general health-care workers as well as a functional referral system. If successful, the model will be integrated into the activities of the National Tuberculosis and Leprosy Control Programme and scaled up nationwide.

A Rare Case of Intramedullary Tuberculosis with Paraparesis
Authors: Acharya Abhijit , Panigrahi Souvagya , Choudhary Ritu Priya , Puppala Sumirini , Dash Atmaranjan
Published: June 2022

Intramedullary tuberculoma (IMT) is considered to be a rare form of spinal tuberculosis (TB). Overall, TB of the central nervous system accounts for approximately 1% of all cases of TB and 50% of these involve the spine. The clinical presentation of spinal intramedullary TB is similar to an intramedullary spinal cord tumor mass. The factors attributable could be malnutrition, poor socioeconomic conditions, and immunodeficiency syndromes. As per the reports, the incidence of primary intramedullary TB is 2 in 100,000 cases among patients with TB. We describe one such patient who presented with progressive asymmetrical paraparesis due to histologically confirmed intraspinal tuberculoma. Paraparesis in spinal IMT is considered to be rare. Hereby, we present the case of a 29-year-old female who presented with asymmetric onset paraparesis of 6 months with associated numbness and tingling began in the left foot 3 months which was ascending in nature. There was no history of stiffness, involuntary movements, flexor spasms, thinning, or fasciculations of muscles. There was a loss of sensation pain, touch, and temperature below L3 with normal reflexes. Power in both the lower limbs was 1/5 as per Medical Research Council (MRC) grading. She underwent a contrast magnetic resonance imaging spine which was suggestive of an intramedullary SOL at D12 vertebral level. The patient underwent surgical intervention with resection of the SOL. Histopathology was confirmed to be an IMT. She was started on Category 1 (antitubercular drugs) and further investigated for primary source, which was found to be negative. We want to emphasize that TB can involve any part of the body. It should be kept as a differential diagnosis of any chronic inflammatory lesion involving the bony skeleton, especially in endemic countries where combined surgical and medical treatment is usually sufficient to provide a cure.
Knockdown of the Type-II Fatty Acid Synthase Gene hadC in Mycobacterium fortuitum Does Not Affect Its Growth, Biofilm Formation, and Survival under Stress
Authors: Sharma Ayushi , Vashistt Jitendraa , Shrivastava Rahul
Published: June 2022

Background:

Mycobacterial fatty acid synthase Type-II (FAS-II) components are major virulence factors exploited as potential targets for developing novel antimycobacterial drugs. The FAS-II enzyme 3-hydroxyacyl-ACP dehydratase (HadC) is important for biofilm development and pathogenesis of Mycobacterium tuberculosis and other mycobacterial species.

Methods:

Literature review and homology search led to the identification of Mycobacterium fortuitum MFhadC gene. Functional interaction study of MFHadC protein was done using STRING. M. fortuitum MFhadC over-expressing (HS) and knockdown (HA) strains were constructed and validated by expression analysis using quantitative polymerase chain reaction. The strains were analyzed for growth behavior and surface spreading ability. Biofilm formation was assayed through crystal violet assay, viability count, and basic fuchsin staining. In addition, survival of the strains was studied under in vitro nutrient starvation and detergent stress.

Results:

STRING analysis showed the interaction of HadC with proteins involved in biofilm formation. The strains HS and HA showed spreading ability on the agarose surface, exhibiting translocation patterns similar to the vector control strain. All three strains showed a similar amount of biofilm formation when analyzed using crystal violet assay, viability count, and basic fuchsin staining. The strains showed no deviation in survival when incubated under nutrient starvation and detergent stress.

Conclusion:

Our results suggest that MFhadC may not be important for the formation and maintenance of biofilm, a factor critically important in M. fortuitum pathogenicity. However, not essential for survival and growth, MFhadC maintains the viability of M. fortuitum under a nutrient-starved environment. Collectively, MFhadC may not be used as a biofilm-specific marker for M. fortuitum.
Quality Implications of Regular Versus Overnight Processing of Stored Human Platelets: An Institutional Study
Authors: Das Subhashish , Harendra Kumar M L
Published: June 2022

ABSTRACT

Background:

Platelet concentrates (PC) are prepared from random donor platelets (RDP) and single donor platelets (SDP) and the various quality parameters of the PC are multifactorial which includes the preparation techniques, types of bags used, holding period prior to processing, type of anticoagulant used, use of additive solutions, the storage conditions after processing, etc. Extending the holding period before processing and ensuring the absence of deleterious affect on the quality parameters of the PC can be extremely beneficial from operational and logistical reasons to meet the increased clinical demand of PCs, particularly for oncology cases and during dengue epidemic.

Aims and Objectives:

The comparative evaluation of various quality parameters including morphological, biochemical and molecular aspects of PCs between fresh whole blood (WB) (8 hrs) versus overnight hold blood (24 hrs) on the 0, 3rd and 5th day of storage.

Materials and Methods:

Fifty units of blood were collected and stored overnight (24 hrs) hours at a temperature of 220C to 240C and processed subsequently. The other 50 units were processed immediately within 8 hours. All the PCs had undergone mandatory serological testing and all the sero-negative PCs had fulfilled quality control parameters. Sterility confirmation was done on 0, 3rd and 5th day of storage. Morphological, biochemical and molecular aspects for both the categories of PCs were studied. For statistical analysis, t-test at 95% confidence interval was done with a P value of <0.05 taken as statistically significant.

Results:

All essential quality parameters in both the categories of PCs were within acceptable limits. No adverse impact on quality was noted in the overnight PCs.

Conclusion:

The preserved quality of overnight PCs along with associated logistic benefits should encourage blood bank management to seriously explore the feasibility of undertaking the 24-hours whole blood holding period (overnight) before preparing PCs.
Prevalence and pattern of maxillofacial injuries and treatment outcome after bear attacks in Jharkhand population
Authors: Vishal  , Rohit  , Shahi Ajoy Kumar , Prajapati V. K. , Prakash Om , Khaitan Tanya
Published: June 2022

Introduction:

Sloth bear, a native species of Indian subcontinent, has a population estimate of 1200–1500 in Jharkhand. Human habitats in proximity to forest reserve cause frequent human–bear interactions and thus bear attack injuries. Face is the most common site affected. This is a prospective study performed to evaluate the incidence and pattern of maxillofacial trauma after bear attack and the outcome of the treatment provided to them.

Materials and Methods:

Patients with bear attack injuries reporting to the outpatient department were recruited for the study. The incidence was recorded in terms of time, month, and site. Details of maxillofacial wounds and fractures were noted. The variables used to analyze the outcome of the treatment were ugly scar, facial asymmetry (eyelid, nose, cheek, and lips), facial nerve paralysis, loss of vision, and alopecia.

Results:

Majority of the cases were reported in April and March. Victims were from Ranchi 4 (26.6%), Gumla 3 (20%), Lohardaga 2 (13.3%), Latehar 2 (13.3%), Simdega 1 (6.6%), Ramgarh 1 (6.6%), Khunti 1 (6.6%), and West Singhbhum 1 (6.6%) districts of Jharkhand. Zygoma (10) was the most affected fractured bone, followed by frontal (9) and mandible (6). Minor ugly scar was found in 14 (93.3%) of the patients, postoperative facial deformity in 12 (80%), unilateral facial paralysis in 2 (13.3%), and alopecia patch in the scalp in 1 (13.3%).

Conclusion:

Spring and early summer are the breeding seasons of sloth bears in Jharkhand. Mahua petal which attracts the wild bear falls from trees during these months causing such human attacks. Loss of vision describes the mutilating nature of bear attack.
Mucormycosis of jaws – literature review and current treatment protocols
Authors: Dewan Hitesh , Patel Hiren , Pandya Haren , Bhavsar Bijal , Shah Urvi , Singh Surya
Published: June 2022

Mucormycosis is a modern-day lifestyle disease that has burst into the health-care scenario. It is an opportunistic fungal infection that proliferates into the immunocompromised host by invasion of the fungus into the paranasal sinuses, thereby invading the palate, maxilla, and orbit. Left untreated it invades the cranial components such as cavernous sinus, skull base, and brain. Mucormycosis invades blood vessels, making these infections highly angioinvasive. We reviewed 45 cases of mucormycois of the head-and-neck region from 2010 to 2020 on the basis of electronic search peer-reviewed journals in Medline (PubMed) database. Presenting symptoms, risk factors, history of extraction, and treatment were tabulated and the data were analyzed. The mean age of patients was 53.8 years. 73.93% of patients had diabetes mellitus, 13.63% of patients had no immunocompromised state, and 8.74% of patients had other medical disorders. About 34.78% of cases had a history of extraction prior to manifestation of symptoms. Mucormycosis remains difficult to treat disease with a high mortality rate. At present, the triad of clinician's awareness, appropriate antifungal therapy, and aggressive surgical intervention represents treatment protocols against the disease.
Piezo-osteotomy in orthognathic surgery
Authors: Raj Harshitha , Singh Madhumati , Shah Anjan Kumar
Published: June 2022

Background:

After the clinical introduction of ultrasound scalpel in recent years, piezosurgery has become competitive with conventional instruments in orthognathic procedures to reduce the operative and postoperative complications reported to occur in association with these surgeries.

Aims:

The aim of this prospective clinical study was to compare intraoperative and postoperative outcomes of both piezoelectric device and the traditional bur technique in orthognathic surgery. Intraoperative bleeding time, operative time, postoperative swelling, and neurological impairment were evaluated.

Materials and Methods:

In this study, a split-mouth technique was applied on ten patients requiring orthognathic surgery. To make the osteotomy cuts, on the one side, piezo-osteotome was used, and on the other side, conventional osteotomy bur was used.

Results:

Duration of osteotomy was found to be greater with piezo osteotomy compared to bur osteotomy. Mild bleeding was observed with piezosurgery. Postoperative swelling was greater on the side of piezosurgery compared to the bur side. Altered neurosensory activity was found to be equal on the 1st day postoperatively, but the piezo side recovered faster compared to the bur side in the 1st month after surgery.

Conclusion:

Piezoelectric device offers better advantages over the conventional bur in orthognathic surgery and hence can be considered an alternative to the bur in some orthognathic procedures.
Electro-surgical management of a traumatic fibroma with clinical assessment of re-epithelialization using methylene blue assay: A clinico-histopathological case report
Authors: Manjunatha Vinayaka Ambujakshi , Vemanaradhya Gayathri Gunjiganur , Kulkarni Manjiri , Machetty Laxmi
Published: June 2022

This article addresses the clinical presentation, diagnosis, histological features, and management of a case of fibroma. Fibroma is proliferative fibrotic lesions of the gingiva and oral mucosa, which may cause aesthetic and functional problems. Fibrous hyperplasia and fibroepithelial hyperplasia are histological alternates of these nonneoplastic lesions. The case demonstrated an overgrowth in the lower back tooth region. The growth was pale in color, sessile, painless, and firm in consistency. The lesion caused discomfort when chewing food, the lesion was excised using dental electrocautery and sent for histopathological assessment. This lesion was caused by trauma or persistent irritation, and histological examination indicates that the cells in the lesion are from the oral mucous membrane. This case demonstrates the need for proper diagnosis, the role of biopsy, and histologic evaluation in the management of fibrotic lesions.
Morpho-functional restoration of an element in esthetic area through modified intentional replantation
Authors: Tagliatesta Luigi , Gaglione Thomas , Arcari Matteo , Rossi Alessandro Luigi
Published: June 2022

This study aims to evaluate the success of the morpho-functional restoration of a tooth with subgingival carious lesion using the modified replantation technique, which entails the rotation of the element of 180° on its axis. This study has a follow-up of 16 months. A 68-year-old man comes to rehabilitate the esthetic and the functionality of element 1.2, affected by destructive carious process extended below the gingival margin. At the clinical and radiological examination, the possibility of a conservative approach is excluded due to the total lack of healthy dental tissue to construct the ferula. It is executed the technique of modified intentional replantation, followed by a rehabilitative phase. After 16 months of follow-up, it can be appreciated the stability of the hard and soft tissue, the lack of pathological probing or symptomatology, and radiographically there is no evidence of bone or root resorption. The modified intentional replantation can be a valid alternative to the surgical lengthening of the clinical crown, to the orthodontic extrusion or to the surgical extrusion. This variation allows obtaining an apical stop during the replanting phase, which contributes to the stabilization of the element. Due to the short follow-up examination from us, further studies are necessary.

Authors: Ahmadi Jamshid , Bazrafshan Amir , Sahraian Ali , Jalali Sara , Fakhermanesh Maedeh , Hooshyari Zahra
Published: June 2022

Objectives:

In this double-blind, randomized clinical trial, the effectiveness of buprenorphine (BUPRE) in the reduction of anxiety symptoms among the methamphetamine (MA) dependents was evaluated.

Materials and Methods:

The 60 MA-dependent patients were randomly assigned to three groups (0.1 mg, 1 mg, and 8 mg of BUPRE), The Hamilton Anxiety Rating Scale was administrated to assess the anxiety symptoms daily at baseline and second to the 5th day after intervention. The inclusion criteria were the MA dependence, age of over 18 years, and absence of any chronic physical illnesses; exclusion criteria were the presence of other drug dependence in combination with MA. The mixed-design analysis of variance was performed for data analysis.

Results:

A significant main effect of time (F = 51.456, P < 0.001) and group (F = 4.572, P = 0.014) and group-by-time interaction (F = 8.475, P < 0.001) were detected.

Conclusions:

This finding supports the efficacy of BUPRE to decrease anxiety. High doses of the drug (1 and 8 mg) were more effective than 0.1 mg. Here was not a significant difference between anxiety score when patients received 1 mg of BUPRE instead of 8 mg.

Published: June 2022

Extended-Spectrum Beta-Lactamase (ESBL) producing bacteria are of great concern to healthcare because of theirresistance to β-lactam antibiotics. This study aims to screen Gram-negative bacteria recovered from fruit andvegetable salads for ESBL production. The bacteria in thirty samples of fruit and vegetable salads purchased fromfood vendors were isolated and identified with standard microbiological methods. The Gram-negative bacteriarecovered were screened for ESBL production by the double disk synergy test (DDST) and brilliance ESBL agar(BEA). The total coliform counts in the fruit and vegetable salads were in the ranges 2.3 - 19.1 x 104 cfu/g and 2.8- 19.4 x 104 cfu/g respectively. Ninety-eight (98) Gram-negative bacteria were recovered from the salad samples.They were Escherichia coli (34.7%), Citrobacter freundii (21.4%), Enterobacter cloacae (10.2%), Enterobacteraerogenes (9.2%), Pseudomonas aeruginosa (9.2%). Klebsiella oxytoca (8.2%), Klebsiella pneumoniae (4.1%) andProteus mirabilis (3.1%). For ESBL production using DDST, 43. 9% (43) of the isolates were positive for the test.On the brilliance agar, 68.4% (67) showed the expected colour change as outlined by the manufacturer. However,five strains of K. oxytoca showed blue growth while sixteen of C. freundii had brown growth. ESBL-producing E.coli strains that were not detected with DDST grew on BEA. This finding showed that ESBL-producing bacteriaare present in fruit and vegetable salads retail in Ago-Iwoye, hence, there is need to take the necessary precautionsduring the preparation and storage of these food products to prevent contamination by these pathogens andsubsequent production of ESBL.

Authors: Umar Aminu A.
Published: June 2022

There is a growing demand to establish reliable method for the detection of cyanobacterial toxins in order to bewell informed on the prevalence of cyanotoxins in our environments. This study employed the underivatizedmethod of analysis to detect the production of BMAA by the axenic cultures of cyanobacterial strains SynechocystisNPLB 2 and Nostoc MAC PCC 8009 using liquid chromatography-electrospray ionization - ion trap massspectrometry (LC/ESI-ITMS). Cyanobacterial cultures were grown in the laboratory for 12 weeks after whichBMAA was extracted using methanol and analysed by LC/ESI-ITMS. Based on retention time, mass-to-chargeratio, and ratio of the product ions, the underivatized method of analysis employed in this study showed that bothSynechocystis NPLB 2 and Nostoc MAC PCC 8009 strains produced BMAA. The results of this study suggests thatthe LC/ESI-ITMS is a promising method for the analysis of BMAA in cyanobacterial matrices.

Published: June 2022

Asymptomatic bacteriuria is a common occurrence among healthy students, with a tendency to develop intosymptomatic urinary tract infections (UTIs). This study was carried out to investigate the occurrence andantimicrobial susceptibility profile of Escherichia coli from the urine of asymptomatic students. A total of 180 midstreamurine samples were collected from apparently healthy students, whose consents were sought. E. coli wasisolated and tested for their susceptibility to commonly used antimicrobial agents using the disk diffusion protocol.Result analysis was done using one way analysis of variance (ANOVA) with the help of SPSS and level ofsignificance taken at p<0.05. The isolates showed resistance against 90% of the antibiotics used in this study with93.3% of the isolates resistant to cefuroxime and 35 % resistant to nitrofurantoin. Multidrug resistance (MDR) wasalso observed where the isolates showed resistance to at least three classes of the antimicrobial agents used in thisstudy. A multiple antibiotic resistance index greater than 0.2 was observed in over 80 % of the isolates. This studyshowed a rare occurrence in which almost all the Escherichia coli isolates showed resistance to over 90% of theantibiotics used in this study with the exception of nitrofurantoin which seems to be the most effective antibioticsagainst all the isolates. This situation portends grave danger to public health; hence, the need for high levelsurveillance and monitoring of the use of antibiotics in therapy as well as the molecular identification of theprevalent resistant strains.
Use of Time-Depth Conversion in Velocity Modeling of Well Data from an Onshore Field Dataset, Niger Delta Area, Nigeria
Authors: Sofolabo A. O. , Diri I. J.
Published: June 2022

The estimation of subsurface velocity is very important in seismic reflection as it controls the quality of the depth images, which is the basis of most geological interpretation. In this paper, time depth conversion technique had been used to develop a one-dimensional velocity model of an onshore field, using a layer-cake method in creating the model and seismic interpretation program to build the velocity model. The Sonic data and the checkshot data of field obtained were converted to time images to represent the true geological depth. The resulting velocity obtained from the model ranges from 188-2677ms-1, which is a true reflection of the subsurface layers velocities (from the unconsolidated to consolidated layers velocities) of most Niger Delta area.

Authors: Obodunrin O. P.
Published: June 2022

In this study, measurements of indoor radon concentrations were undertaken, and the annual effective dose to the residents relative to both general and field occupancy were estimated. The measurements were carried out in residential environments of Lagos Nigeria using CR-39 solid state nuclear track detectors. The detectors were mounted in ninety-eight different rooms within the selected buildings at approximate height of 2 m above the ground and exposed for a period of six months. Data were obtained from the residents with the use of semi-structured self-administered questionnaire. The indoor occupancy hour of 9.8, 1.8, 2.9 and 6.6 were recorded for bedroom, bathroom/ toilet, kitchen and living room respectively in the study area. The maximum and minimum occupancy factor recorded were 96% and 76% respectively from the data obtained. The dose received by a resident, ranged from 150.2 – 222.3 µSvy-1 and 166.7 – 185.3 µSvy-1 computed with the field occupancy factors and the general occupancy factor respectively.

Copper cadmium sulphide (CuCdS) thin film (TFs) is one of the most important ternary semiconductors for the development of various modern optoelectronic devices. In this study CuCdS TFs were deposited on soda-lime glass substrates utilizing chemical bath deposition (CBD) procedure at normal room temperature. The deposited materials were characterized by UV-Vis spectrophotometer and four-point (4-point) probes for its optical and electrical (O&E) properties. The band gap (BG) energy was determined to be 2.36 eV using the absorption spectrum fitting (ASF) method. Optical constants such as refractive index (n), extinction coefficient (k), real (Ɛᵣ) and imaginary (Ɛᵢ) dielectric constants, dielectric loss (tan ϕ), electrical susceptibility (Xc) have been calculated at a wavelength (𝜆) of 900 nm. The film also demonstrates an optical transmittance of above 75% at wavelength greater than 900 nm. The electrical resistivity and conductivity were estimated to be 2.5 Ω/cm and 0.4 (Ω/cm)-1 respectively. These determined properties confirmed CuCdS TFs as a potential ternary material for various optoelectronic applications.
Rethinking Varieties of Capitalism and growth theory in the ICT era*
Authors: Soskice David
Published: June 2022

Going beyond the Varieties of Capitalism comparative analysis, a theory of advanced capitalism is developed to explain what has been driving advanced capitalism through the massive creative destruction of the information and communication technologies (ICT) revolution of recent decades. Second, it is argued – reconfiguring Varieties of Capitalism – that the advanced capitalist economies should be seen not just in terms of comparative capitalisms, but as an advanced world innovation system of interacting advanced economies. Critically, the dominant position in that system is the (hegemonic but also fragile, problematic and handicapped) United States as the world driver of radical innovation: this reflects the key role of its top research universities, their diasporas and associated deregulated high-risk-taking venture capitalist and investment banking ecosystems; its decentralised and business-porous political and legal systems; and its dominance ab initio of digitalisation. Problematic has been the major reduction since the early 1990s in Federal R&D, itself a consequence of the anti-public-expenditure Republican gridlock in Congress, and in turn the result of the political, geographical and socioeconomic polarisation associated with technological creative destruction more dramatically in the US than elsewhere. Third, it addresses the paradox – in the contemporary technologically revolutionary age – of productivity growth falling below that of the Fordist era. It is argued that Schumpeterian growth expectations play a much larger role in R&D investment in the high-sunk-cost and high-risk US-centred ICT era than in the relative stability of Fordism and Chandlerian corporations; the author sets out a simple Keynesian–Kaldorian expectations-based multiple equilibrium productivity growth model, where major crashes shift economies down to lower growth equilibria. The conclusion raises six areas of future work which stem from the approaches outlined above.

Los atentados al Estado de Derecho. Una reflexión desde el Derecho Público.
Authors: Sarmiento Acosta Manuel Jesús
Published: June 2022

El Estado de Derecho implica el sometimiento del poder al Derecho; en España supuso un gran logro en 1978, pero se observan perversiones muy significativas en distintos sectores que constituyen el corazón del Estado, como los excesos de la Administración tributaria, la colonización por los partidos políticos del gobierno del Poder Judicial, la exacerbación del derecho al voto al margen de lo que permite el ordenamiento o la vulneración de los principios de mérito y capacidad, entre otros casos. Es obligado rectificar el ordenamiento jurídico en estos ámbitos para asegurar la misma existencia del Estado de Derecho en la actualidad.
El principio de recuperación de costes en la Ley de Aguas de Andalucía
Authors: Martín Martín Jesús Enrique
Published: June 2022

La Ley 9/2010, de 30 de julio, de Aguas de Andalucía desaprovechó la ocasión para haber regulado un régimen económico-financiero propio sin remitirse a lo establecido en la legislación básica y, así, alcanzar la implantación del principio de recuperación de costes en Andalucía. Ello ha provocado que, al igual que en el resto de España, el porcentaje de recuperación de los costes sea inferior al 80% y que desde los sectores medioambientales y sociales se reclame con insistencia una reforma en profundidad de la fiscalidad del agua tanto en Andalucía como en España.

Generation of runaway electrons in fusion experiments can drive to serious damage of plasma devices components. Injection of gas with a large mass number decreases the generation processes. Also, magnetic perturbations decrease generation of runaway electrons by increasing the loss rate. We investigated the influence of working gas pulse injection and natural fluctuations of the magnetic confining field on runaway electrons dynamics. The interaction of runaway electrons with an Alfven wave in plasma is noted.
VELOСITY DISPERSION OF DUST PARTICLES CONFINED IN A SHEATH
Authors: Zasenko V.I.
Published: June 2022

Velocity distribution of dust particles localized in a plasma sheath near an electrode was found in a number of experiments. Velocity dispersion indicated that the kinetic temperature of dust grains significantly exceeds the temperature of plasma environment. Consequently, the question arose about the stochastic mechanisms of anomalous heating of grains. We propose the model in which the kinetic energy is due to the significant potential energy that grains have at the moment of their release from the crystalline structure on melting. Stochastic processes only modify the regular motion of dust grains, forming a velocity distribution similar to а Gaussian.

The paper describes the design features of a gas valve for the axial (parallel to the axis of the accelerator) working gas supply into the accelerator channel. The results of gas-dynamic studies of the injectors are presented. The amount of the working gas inlet was investigated as a function of gas pressure under the blocking valve element. A strong dependence of the amount of the injected working gas on the electric current value in the control coil was found.
