Authors: Akinnagbe Oluwole Matthew , Ipinmoye Obadamilola Enitan
Published: August 2022

The study examined the effects of urban agriculture on households’ livelihoods in Ondo State, Nigeria. A multistage sampling procedure was employed in selecting 150 respondents. Data were obtained through the use of interview schedule and analysed using percentage, charts, and mean statistic. Results revealed that the major crop and livestock kept were leafy vegetables (100.0%) and broilers chicken (57.0%), respectively. The majority (82.0%) of the respondents that practised urban agriculture had no contact with extension agent. The practice of urban agriculture had significant effects on respondents’ livelihood in term of improvement in standard of living from 85.0% to 98.0%, and improvement in saving pattern from 66.7% to 100.0%. The practice of urban agriculture had also led to an improved knowledge of the respondents. The extension services of Ondo State Agricultural Development Programme should be extended to those practicing urban agriculture. This will go a long way in improving and sustaining households’ livelihoods.
Creating a Functional Health System for Nigeria
Authors: Odusanya O.
Published: August 2022

Background: Health systems are more than static health facilities. The World Health Organization has identified six building blocks of the health  system namely: human resources for health, service delivery, medicines, vaccines and technology, health information, health financing and  leadership and governance. This paper examines the Nigerian health system and posits that it is not functional.Discussion: The dysfunctional state is a result of chronic neglect of both the building blocks of the health system and the wider determinants of  health such as education, sanitation, and food security in addition to the lack of synergy between the health and non-health sectors.Conclusion: Creating a functional health system in Nigeria does not require fresh policies rather the political will and commitment of resources to  improve the quality of life of the citizens in the non-health sector and the implementation of the numerous policies and strategies in the health  sector. Adequate attention should be paid to primary health care.

Background: Fire outbreak in a healthcare facility presents enormous challenge and a need for rapid response. The purpose of this study was to  examine fire safety (FS) knowledge of workers and preparedness measures in Federal Medical Centre Umuahia, Nigeria.Methods: This cross-sectional study involved 27 buildings and 310 employees from different units and departments, recruited by convenient non-  probability sampling technique. A walk-through observational checklist and self-administered questionnaire were used to collect data which was  analysed with SPSS software, version 20. Association between knowledge of FS and respondents’ working experience and FS training was measured  using χ2- test. P ≤0.05 was assumed to be statistically significantResults: The highest proportion of participants were administrative staff 93 (30%), followed by medical doctors 80 (25.8%) and nurses 63 (20.3%).  Only 28 (9.0%) had received training on FS, 109 (35.2%) knew how to operate a fire extinguisher, while 139 (41.9%) had knowledge of the location of  fire extinguisher in their workplaces. Twenty-six (8.4%) knew the emergency number(s) to call if fire occurs. Only 107 (34.5%) of them had good  knowledge of fire safety. Training on FS was significantly associated with knowledge of fire safety (p=0.026). All the buildings lacked necessary measures for FS.Conclusion: FS knowledge and level of preparedness were unsatisfactory in the hospital, which may constitute serious threat to the safety of  workers and patients. The hospital management should implement regular FS training programmes for the workers to improve their knowledge, as  well as put in place other FS measures.

Published: August 2022

A comparative study to determine the impact of gas flaring (GF) on some phytoconstituents of five commonly used green leafy vegetables was done. Two locations in south-east states in Nigeria, Ibeno in Akwa Ibom State, a gas flaring (GF) community and Nsukka in Enugu State, a non-gas flaring (NGF) community, were used. Five fresh green leafy vegetable samples were used for this study (Amaranthus hybridus, Gnetum africanum, Talinum triangulare, Telfairia occidentalis, and Vernonia amygdalina) and were obtained from community farmlands during the rainy season between August and November, 2016. After collecting and identifying the green leafy vegetables from five different farmlands in GF and NGF areas and at a distance of about 2km radius from the flare site in GF communities, detailed laboratory analysis was done for alkaloids, flavonoids, saponins and tannins. For A. hybridus, the flavonoid and tannin contents in NGF community were significantly (p<0.05) higher than in GF community; G. africanum, the alkaloid and tannin contents were higher in NGF community; T. triangulare, the alkaloid content alone was higher in NGF community; T. occidentalis, the alkaloid, flavonoid, saponin and tannin contents were significantly (p<0.05) higher in the NGF community; V. amygdalina, the tannin content alone was higher in NGF community compared to the GF community. Most green leafy vegetables from NGF community produced higher and better phytoconstituent concentrations than the GF community. This can be attributed to the non-pollution of the former environment.
Isosorbide mononitrate inhibits myocardial fibrosis in diabetic rats by up-regulating exosomal MiR-378
Authors: Zhao Kaidi , Zhang Junyi , Li Ping , Yan Rongqiang
Published: August 2022

Purpose: To investigate the effect of isosorbide mononitrate on diabetic cardiomyopathy (DCM), and the potential mechanism of action.Methods: The effects of isosorbide mononitrate and isosorbide mononitrate + GW4869 on cardiac function and myocardial fibrosis in DCM rats were determined via hemodynamics, hematoxylin-eosin (H&E) staining and Masson staining. Exosomes were extracted from the serum, and the differential expressions of microribonucleic acids (miRNAs) related to myocardial fibrosis were determined by reverse transcription-polymerase chain reaction (qRT-PCR). Western blotting was performed to determine the effects of isosorbide mononitrate and isosorbide mononitrate + GW4869 on IGF1R/STAT3 signaling pathway.Results: Isosorbide mononitrate exerted a protective effect against DCM--induced cardiac dysfunction and myocardial fibrosis, while such a protective effect was suppressed by the exosome inhibitor GW4869 (p < 0.05). The expression of miR-378 in exosomes significantly rose in isosorbide mononitrate group. The increased expression of miR-378 in vitro inhibited the proliferation of primary myocardial fibroblasts, and reduced the expression of myocardial fibrosis markers (p < 0.05). Luciferase reporter assay data showed that miR-378 negatively regulated the expression of IGF1R by direct binding to IGF1R mRNA 3'-untranslated region (3'UTR). In primary myocardial fibroblasts, miR-378 mimic significantly reduced the protein expressions of IGF1R, p-STAT3/STAT3 and c-Myc (p < 0.05). Isosorbide mononitrate lowered the protein expressions of IGF1R, p-STAT3/STAT3 and c-Myc, but the inhibitory effect was weakened by the exosome inhibitor, GW4869 (p < 0.05).Conclusion: Isosorbide mononitrate inhibits myocardial fibrosis in diabetic rats by up-regulating exosomal miR-378, and targeting the axis of STAT3/IGF1R. The results of this study may provide a new insight into the treatment of DCM.

Published: August 2022

Purpose: To investigate the combined diagnostic value of multi-slice spiral computerized tomography (MSCT) and serum C-reactive protein (CRP) levels in children with mycoplasma pneumonia (MPP) after azithromycin treatment.Methods: Clinical data for 60 children with MPP who were treated in The First People's Hospital of Chenzhou, Chenzhou from February 2019 to February 2020, were retrospectively analyzed. All children were treated with azithromycin. Serum CRP levels were measured using immunoturbidimetric endpoint assay, while MSCT examination was done before and after treatment. This was a self-control clinical study in which the 60 patients served as their own controls. Thus, results obtained before treatment (control group, CG) were compared with those obtained after treatment (study group, EG). Within the same period, 60 healthy subjects were selected as the healthy group (HG), and were subjected to MSCT examination and serum CRP assay. The diagnostic results of CT were analyzed, and the responsiveness, selectivity, and positive and negative predictive values of the combination of MSCT and serum CRP levels were calculated.Results: Pre-treatment serum CRP level was higher in CG than in EG and HG, and CRP level was higher in EG than in HG (p < 0.001). The MSCT imaging features of EG were significantly different from those of CG (p < 0.05). The probabilities of bronchial wall thickening, hilar and mediastinal lymphadenopathy and pleural effusion were significantly higher in CG than in EG (p < 0.05). The responsiveness, selectivity, and positive and negative predictive values of combination of MSCT and serum CRP in MPP children after azithromycin treatment were 70.0, 66.7, 67.7 and 69.0 %, respectively.Conclusion: The combination of MSCT examination and serum CRP levels resulted in high diagnostic efficiency, and it may be useful for monitoring MPP in children after azithromycin treatment. Therefore, the combined procedure may reduce the burden on families of MPP children by enhancing efficiency of diagnosis of the disease.

Authors: Liao Lijuan , Huang Wenwu , Xiong Chun
Published: August 2022

Purpose: To investigate the diagnostic significance of two-dimensional echocardiography (2DE) combined with coronary angiogram in patients with acute myocardial infarction, and to determine the effectiveness of atorvastatin.Methods: Patients (n = 100) with acute myocardial infarction admitted in Affiliated Hospital of Jinggangshan University, Ji’an, China, were divided into control group (CG) treated with conventional therapy, and study group (EG) treated with atorvastatin, in addition to conventional therapy. The diseased vessels examined by echocardiography and coronary angiogramv were recorded and compared. The effectiveness of atorvastatin treatment was assessed by evaluating myocardial injury, oxidative stress, vascular injury and cardiac function indices, viz, left ventricular ejection fraction (LVEF), left ventricular end-diastolic internal diameter (LVEDD), left ventricular end-systolic internal diameter (LVESD), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV).Results: The number of double and multiple lesions shown on coronary angiogram were significantly higher than those shown in echocardiography. Phosphocreatine kinase (CK), creatine kinase isoenzyme (CK-MB) and cardiac troponin T (cTnT) improved significantly in both groups after surgery, with CK-MB significantly lower in EG than those in CG at 1 and 3 days post-operation. Interleukin-6 (IL- 6) was significantly lower in EG than in CG at 1 and 7 days after the surgery (p < 0.05). N-terminal Btype natriuretic peptidogen (NT-proBNP) was lower in EG than in CG on the 3rd day after surgery (p < 0.05). Superoxide dismutase (SOD) was significantly higher in EG than in the CG at 1, 3 and 7 days after surgery. The QRS scores significantly improved in both groups after surgery (p < 0.05).Conclusion: Echocardiography, when used in combination with coronary angiogram, accurately assesses the coronary lesions in acute myocardial infarction, and atorvastatin treatment after PCI reduces myocardial injury, relieves inflammation, and promotes the recovery of cardiac function in patients.

Purpose: To investigate the efficacy and safety of mycophenolate mofetil (MMF) combined with lowdose steroids in the treatment of pediatric systemic lupus erythematosus (pSLE).Methods: A total of 76 children were diagnosed and admitted with SLE, lupus nephritis (LN) and type IV diffuse proliferative glomerulonephritis at Hainan Women and Children’s Medical Center, Haikou, China from March 2017 to December 2018, had their clinical data analyzed retrospectively. Among them, 38 children received methylprednisolone pulse combined with MMF and intermittent oral low-dose glucocorticoids (GC), labelled MMF group, while the remaining 38 children, which served as control group, were treated with oral GC and transitional reduction. Pertinent biochemical parameters were evaluatedResults: Compared with control group, MMF group showed a notably lower level of erythrocyte sedimentation rate (ESR), a higher level of complement C3, lower level of serum creatinine (Scr) and 24-h urine protein level 6 months after treatment (p < 0.05). Albumin level was higher in MMF group at 6 months and 12 months after treatment than in the control group. Compared to control group, the SLEDAI score in MMF group was significantly lower at 6 months and 12 months after treatment (p < 0.05). Body mass index, triglyceride, fasting blood glucose and intraocular pressure levels in the MMF group were significantly lower than those in the control group (p < 0.05). Post-treatment, peripheral blood CD3+ and CD4+ T lymphocytes, CD4+/CD8+ ratio and NK cell levels in the two groups were significantly increased, while CD8+ T lymphocyte level declined.Conclusion: MMF combined with low-dose methylprednisolone controls symptoms early and mitigates renal injury in the treatment of pSLE. It is also safe, and effectively regulates the patient's cellular immune function.

Published: August 2022

Purpose: To investigate the effect of S-adenosyl-L-methionine (SAM) on angiogenesis and fibrosis in the heart of rats with myocardial infarction (MI), and to determine the mechanism of action.Methods: Sprague Dawley rats with MI received SAM treatment (15 mg/kg) intraperitoneally. The cumulative survival (%) of rats was recorded to determine their rate of survival. Hematoxylin-eosin staining, echocardiography, and hemodynamics were also performed. In addition, the effects of SAM vascular regeneration in the rats were analyzed by determining the expression of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF) and hypoxia-inducible factor 1-α (HIF1-α) in rats.Results: The 8-week survival rate of the MI group was significantly lower than that of the sham group, while SAM significantly improved the survival rate of the rats. In addition, SAM improved the contractile and diastolic heart function in the rats and also increased the ventricular pressure change. Furthermore, SAM elevated the expressions of VEGF, bFGF and HIF1-α in rat myocardium and serum. In myocardial tissues of SAM-treated rats, the expressions of collagen I, collagen III and α-sma were reduced, indicating that SAM inhibited myocardial fibrosis. In addition, SAM promoted cardiac angiogenesis by activating Jagged1/Notch1 signaling pathway.Conclusion: SAM promotes angiogenesis of the myocardium by activating Jagged1/Notch1 signaling pathway and inhibiting fibrosis in rat myocardium. Therefore, SAM effectively inhibits ventricular remodeling in rats after MI, thereby improving the rats’ heart structure and function. The results may provide new targets for the treatment of myocardial infarction.

Published: August 2022

Промысловый лов неводом – один из самых распространенных видов лова рыбы (не считая траулерного). При таком методе добычи рабочий процесс на судне состоит из нескольких операций, где наиболее трудоемкая и затратная по времени – это выборка невода. Для ее осуществления чаще всего применяются неводовыборочные машины фрикционного типа. Основной принцип работы данных механизмов основан на действии силы трения, за счет которой происходит зацепление между делью и барабаном фрикционной машины достаточной силы, чтобы произвести выборку орудия лова. Главным показателем этой силы является коэффициент трения. В статье представлены методика проведения и результаты экспериментальных исследований по определению данного коэффициента для рыболовных делей на барабане механизма фрикционного типа (МФТ). Описанные опыты основаны на предыдущей работе авторов, связанной с их планированием. Для выполнения экспериментов были изготовлены сетные образцы с заданными параметрами, соответствующие реальным неводам, применяемым на промысле. Каждый из них взаимодействовал с тремя стальными барабанами различных диаметров при разных углах дуги контакта. С помощью тензодатчика, подключенного к тензостанции "MIC-200", фиксировались значения натяжения набегающей ветви (S1) и строились графические зависимости S1 от времени эксперимента (t). Чтобы определить поведение коэффициента трения относительно нормальной площади контакта (A_n), используя полученные максимальные значения S1 (S1max) и ширину жгута дели на барабане (b_б), строились графические зависимости S_1max=f(A_n,C_э). После этого были сделаны соответствующие выводы, и спланировано дальнейшее продолжение исследований.

Published: August 2022

Чем выше влажность осадка, тем выше затраты на его дальнейшую переработку. Целью обезвоживания агломерированного шлама является снижение затрат на последующую сушку и транспортировку. Работа посвящена изучению параметров флокуляции сточных вод катионными флокулянтами с последующим фильтрованием осадка на пресс-фильтрах. Для улучшения обезвоживания шлама использовали химические реагенты – катионные полиэлектролиты "Зетаг-7664", "Зетаг-7689" и "Зетаг-7692". Определяли скорость осаждения твердых частиц, флокулирующую способность и флокулирующий эффект, а также влажность осадка после фильтрования на пресс-фильтрах. Установлено, что наибольшей скоростью осаждения (7 мм/с), наибольшими флокулирующей активностью и флокулирующим эффектом (0,66 и 26,2, соответственно) обладает среднекатионный флокулянт "Зетаг-7689". Доказано, что после фильтрования наименьшую остаточную влажность имеет среднекатионный флокулянт "Зетаг-7689" (36 %). В высококатионном "Зетаг-7664" и низкокатионном "Зетаг-7692" отмечалась остаточная влажность после флокуляции и фильтрования – 39 и 37 %, соответственно. Остаточная влажность осадка, отфильтрованного на фильтр-прессе, соответствует технологическим требованиям. Выделение воды из этой структуры при фильтрации можно объяснить явлением капиллярности. Между частицами образуется мениск жидкости. В мениске с противоположной стороны жидкости капиллярные потенциалы направлены в противоположные стороны, но их абсолютные значения не равны. В результате жидкость движется по капилляру до тех пор, пока потенциалы не сравняются. Для достижения разумного обезво-живания осадка необходимо провести пробную флокуляцию, изучить процессы адсорбции полиэлектролитов на осадке, реологические свойства суспензий сточ-ных вод и растворов флокулянтов. Необходимо выбрать и контролировать пара-метры фильтр-пресса.

Увеличение численности бобра речного (Castor fiber) в Калининградской области обусловило необходимость принятия мер по ее регулированию. Мясо бобров употребляют в пищу во многих странах, оно используется для производства мясной продукции, в том числе консервов и колбасных изделий, качество которых зависит не только от показателей безопасности и пищевой ценности сырья, но и от его реологических свойств и способности фарша к формованию. Для повышения пищевой ценности, органолептических показателей и рас-ширения ассортимента колбасных изделий применяются пищевые растительные компоненты (тыквенный шрот, капустный порошок, смесь пищевых волокон пшеницы и подорожника). В работе изучено их влияние на влагоудерживающую способность (ВУС), глубину погружения пенетрометра, предельное напряжение сдвига (ПНС), эффективную вязкость и адгезионные свойства фарша из мяса боб-ра. Во всех образцах фаршей с добавлением растительных компонентов показа-тель ВУС превысил значение показателя контрольного (50,75 %), что обусловило более сочную и плотную консистенцию и меньшие потери влаги фарша при теп-ловой обработке. Наибольшей сдвиговой прочностью и наименьшей вязкостью обладал образец с добавлением растительных волокон пшеницы и подорожника (488,5 Па и 15740,7 МПа∙с соответственно), тогда как внесение тыквенного шрота и капустного порошка по сравнению с контрольным практически не повлияло на ПНС, а вязкость фарша возросла. Липкость фарша с добавлением растительных компонентов, характеризуемая адгезионными свойствами в виде усилия отрыва, изменилась незначительно по сравнению с контрольным образцом (0,359 кПа). Выявлено, что наилучшими структурно-механическими свойствами обладал образец фарша с внесением смеси пищевых волокон пшеницы и подорожника.

The development of the world of work is growing so rapidly with the outsourcing work system. The outsourcing system is a work system that uses the services of a power expert in managing a particular job or project. There are some negative perceptions from the public about the status of outsourced employees because they are considered to have lower compensation rights and there is no guarantee of career certainty and employment status in the long term. In addition, the number of complaints and dissatisfaction with receiving compensation for outsourcing employees, directly or indirectly can affect work motivation. This study focuses on the motivation and compensation of the Outsourcing Security Worker Unit at PT Pesonna Optima Jasa in Sleman Yogyakarta entitled "The Meaning of Compensation in the Perspective of Survival". The purpose of this research is to find out: 1. perceptions of outsourcing work and compensation, 2. employee motivation and reasons for staying as outsourced employees. In this study, the authors used qualitative research methods with a case study approach and data collection methods in the form of interviews and documentation. Speakers are seven people.

Potencial do sistema fotovoltaico como uma alternativa ao suprimento energético em irrigação no Brasil
Authors:   , Valadão Giovana Franco
Published: August 2022

A irrigação é uma prática importante para garantir a produção agrícola em épocas com precipitação reduzida. Isso garante incremento da produtividade e rentabilidade econômica. No entanto, a irrigação requer um alto consumo de energia elétrica. O uso de fontes renováveis de energia na irrigação pode auxiliar na diversificação da matriz elétrica brasileira e diminuir o uso das fontes não renováveis. O objetivo deste trabalho foi a viabilidade econômica do sistema fotovoltaico como alternativa a fontes tradicionais de energia para o bombeamento na irrigação de áreas agrícolas. Foram avaliadas duas situações, divididas em dois capítulos, do uso do sistema fotovoltaico: conectado e não conectado à rede elétrica. No sistema não conectado à rede, o desempenho financeiro do sistema fotovoltaico foi comparado ao desempenho de um sistema de bombeamento a diesel. Também foi analisado, neste último, o impacto da venda de créditos de carbono na viabilidade do sistema fotovoltaico. O custo do ciclo de vida (LCC) foi a métrica utilizada para a análise de viabilidade econômica. O sistema fotovoltaico foi considerado viável se seu LCC foi menor ou igual ao LCC daquele ao qual está sendo comparado. Para o sistema conectado à rede elétrica foi observado que, em todas as regiões geográficas do país, houve viabilidade econômica do sistema fotovoltaico. No entanto, essa viabilidade é condicionada ao nível de irradiação e à alíquota do Imposto sobre Circulação de Mercadorias e Serviços (ICMS). Para o sistema não conectado à rede elétrica foi obtida viabilidade para grande parte do território nacional e a porcentagem de áreas viáveis aumentou consideravelmente com a venda do crédito de carbono. O sistema fotovoltaico é uma alternativa promissora para ambos os sistemas - conectado e não conectado à rede elétrica. Vale destacar também que a viabilidade financeira tende a aumentar conforme a requisição de energia elétrica aumenta. Palavras-chave: Sistema fotovoltaico. Energia na irrigação. Mapeamento de potencial fotovoltaico. Energia renovável em sistemas de irrigação.
