Published: August 2022

The study examined economics of smoke Catfish in Kainji Lake Basin, Nigeria. Random sampling technique was used to select 80 farmed-catfish processors from 20 communities. Primary data were collected through interview schedule and presented using percentages, mean, and 2-stage least square regression analysis. Results showed that the use of local oven (banda kilns) constitute the majority (at least 67%) of the method used in fish smoking. Roles such as gutting, folding, salting/brining, setting of fire and fish monitoring were mostly performed by the women, while the men and youths supply fire woods as well as fish arrangement on racks. The average gender ratio between the men, women and youths was 0.80, indicating a near gender equality in terms of value of fixed assets, revenue, employees and wage. Profitability indicators showed that smoke fish processing is a viable business with return on investment of 11.71 % for the men, 9.99 % for the women and 8.48 % for the youths respectively. The major determinants of netincome were age, experience and initial capital investment. Hence, it is recommended that the processing industry should be strengthened through subsidy on improved smoking kilns to enable processors produce high quality processed farmed catfish.
Work Facets Predicting Overall Job Satisfaction among Teachers in Selected Secondary schools in Ibadan South-West Nigeria: A Minnesota Satisfaction Questionnaire Survey

Published: August 2022

Background: Global measures are often used to assess employees’ job satisfaction. However, important information is lost when this approach is adopted. The use of multidimensional approach provides robust information for potential intervention. This study aimed to assess the work facets predicting the overall single-item job satisfaction measure among teachers in Ibadan, Nigeria.
Methods: This was a cross-sectional descriptive study conducted among 476 secondary school teachers selected using a multistage sampling method. A structured questionnaire was used for data collection while data was analyzed using SPSS version 26. The Minnesota Satisfaction Questionnaire (MSQ) and a single-item satisfaction measure assessed satisfaction. A linear regression model of the overall job satisfaction was developed. P-value ≤ 0.05 was regarded as statistically significant.
Results: The mean age of respondents was 38.1±9.0 years. Majority of respondents were females 263 (55.3%) and married 363 (76.3%). The respondents expressed above average satisfaction with all work facets except compensation 161 (33.8%) and work conditions 223 (46.8%). The work facets which significantly predicted overall job satisfaction included: supervision-human relations (β = 0.121: 95% CI = 0.013 to 0.229; p = 0.028);policies & practices (β = 0.111: 95% CI = 0.021 to 0.201; p = 0.016); compensation (β =0.125: 95% CI = 0.035 to 0.214; p = 0.006) and recognition (β = 0.113: 95% CI = 0.006 to 0.220; p = 0.039)
Conclusion: Overall job satisfaction was mostly predicted by factors extrinsic to the job, so these could be specifically targeted for interventions to improve job satisfaction among teachers.
Bioaccumulation and depuration of zinc in the tissues of Heterobranchus longifilis exposed to zinc oxide nano-particles
Authors: Abdulkareem SI , Owolabi OD 
Published: August 2022

Industries use zinc oxide nano-particles (ZnO-NPs) to produce most commercial and medicinal goods, but indiscriminate discharge of their effluents into the aquatic environment may accumulate in the tissues of the fish. The ability of these metal oxides to accumulate in the tissue of fish due to their nano size could lead to a reduction in the nutritional value of the fish. Therefore, this study aimed to evaluate the rate of zinc bioaccumulation in tissues of Heterobranchus longifilis. Juveniles of H. longifilis were exposed to sub-lethal concentrations (0.0, 6.00, 8.00, 10.00, 12.00 mg/l) of ZnO-NPs for 60 d and depurated for 30 d. At the end of each experiment, fish were sacrificed and analyzed for bioaccumulation. The increasing order of concentration of zinc was as follow: bone< muscle < blood < skin < kidney < liver < GIT < gills having 0.068mg/g to 0.263 mg/g from muscle to gills. That was above the permissible limits (0.050 mg/g) in fish tissues, except in the bone with 0.054 mg/g, which was still within the acceptable limits. Gills accumulated the highest (0.263 mg/g) content of zinc, and bone had the lowest (0.054 mg/g). After the depuration period, the content of zinc in the tissues decreased in all the tissues but still remained above the maximum permissible limits in gills, GIT, kidney, liver and skin (0.175 mg/g, 0.162 mg/g, 0.066 mg/g, 0.071 mg/g and 0.073 mg/g respectively). However, the bone, blood and muscle were able to depurate the zinc content to values (0.031 mg/g, 0.034 mg/g, and 0.044 mg/g, respectively) below the acceptable limits of Zn in fish tissues. The results indicated that zinc from ZnO-NPs bioaccumulated in H. longifilis tissues, but the fish could depurate the metal naturally. However, the ability to depurate the bioaccumulated metal is time-dependent.
Aromadendrin protects mouse liver from sepsis-induced injury by inhibiting NF-κB signaling pathway
Authors: Zhou Zhihui , Yin Qun 
Published: August 2022

Purpose: To investigate the protective role of aromadendrin in septic liver injury in mice, and its mechanism of action.Methods: Eight-week-old male C57BL/6 mice (n=6 for each group) were administrated with aromadendrin (SMB00175, Sigma-Aldrich) at 0 mg/kg, 30 mg/kg and 60 mg/kg via a hypodermic intraperitoneal injection. HE staining was used to examine liver histopathological structural changes in the liver while DAPI/Tunel staining was employed to evaluate liver cell apoptosis. The mRNA expression levels of TNF-α, IL-1β and IL-6 were determined by quantitative reverse transcriptionpolymerase chain reaction (qRT-PCR). Moreover, enzyme-linked immunosorbent assay (ELISA)was applied to assess the levels of TNF-α, IL-1β and IL-6, as well as the activities of catalase (CAT), antioxidant glutathione (GSH), superoxide dismutase (SOD) and malondialdehyde (MDA). Moreover, the protein levels of p65, p-p65, p-IκBα and IκBα were analyzed by Western blotting.Results: The liver tissues exhibited severe structural damages, with edema, necrosis, and neutrophil infiltration, but recovered as a result of aromadendrin treatment (p < 0.05). The increased serum levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in CLP mice were reduced by aromadendrin, which also attenuated liver injury and cell apoptosis. Aromadendrin inhibited the levels ofu TNF-α, IL-1β and IL-6 in the mice, while the activities of GSH and antioxidant enzymes (SOD and CAT) were also significantly lowered in the mice, but attenuated by aromadendrin (p < 0.05). Aromadendrin also prevented the increased level of MDA, and suppressed the phosphorylation of p65 and IκBα (p < 0.05).Conclusion: Aromadendrin protects mouse liver from sepsis-induced injury by inhibiting NF-κB signaling in vivo, thus suggesting a potential strategy for the therapy of sepsis-induced liver injury.

Purpose: To determine the efficacy of combined use of nebulized epinephrine inhalation and pulmicortrespules in the treatment of emergency pediatric laryngitis and, its impact on the incidence of adverse reactions.Methods: A total of 100 cases of pediatric laryngitis admitted in The People’s Hospital of Zhangqiu District between December 2018 and December 2020 were randomly assigned (1:1) to receive either pulmicort respules (control group) or pulmicort respules plus nebulized epinephrine inhalation treatment (study group). Outcome measures included level of effectiveness and adverse reactions.Results: Pulmicort respules plus nebulized epinephrine inhalation treatment was associated with shorter remission time for dyspnea, wheeze, croup, and hoarseness versus pulmicort respules. The combination treatment produced higher total effectiveness of 96 % than pulmicort respules with total effectiveness of 82 % (p < 0.05). After treatment, both groups had decreased serum levels of interleukin-8 (IL-8), IL-6, C-reactive protein (CRP), and tumor necrosis factor (TNF)-α, with markedly lower levels in the group given nebulized epinephrine inhalation in combination with pulmicort respules (p < 0.05). Compared with patients given pulmicort respules only, those given combination treatments had a significantly shorter hospitalization time and a lower incidence of adverse reactions (4 vs 8 %; p < 0.05).Conclusion: Nebulized epinephrine inhalation in combination with pulmicort respules has high safety in the treatment of emergency pediatric laryngitis, and it significantly reduces clinical symptoms, inflammatory response, and hospital stay. However, further clinical trials are required prior to its use in clinical practice.

Published: August 2022

Зубчатые колеса являются одними из самых распространенных деталей, входящих в различные машины и механизмы. Следовательно, повышение производительности и качества их изготовления – это одна из важнейших задач, стоящих перед технологами и инструментальщиками всего мира. Множество зубчатых колес для винтовых зубчатых передач имеют различную конструктивную форму, изготовление которой требует разнообразия технологий и зуборезных инструментов, основанных на схемах формообразования третьего класса. Такие передачи широко распространены в общем машиностроении и при-меняются в механизмах с малыми мощностями и значительными передаточными отношениями. Бесшумность и плавность работы передач являются одними из их основных преимуществ. Если передаточное отношение в них меньше восьми, то характер касания зубьев – точечный. Начальное касание зубьев происходит в точ-ке, при этом в зоне контакта возникают значительные скорости скольжения, при-водящие к интенсивному износу зубьев. В данной статье разработана винтовая зубчатая передача, имеющая линейный характер касания зубьев при любом пере-даточном отношении. От размеров пятна контакта в значительной степени зави-сит нагрузочная способность зубчатых передач и прежде всего их износ. Найдено пятно контакта в винтовых зубчатых передачах, а также в цилиндро-гиперболоидных, имеющих разные геометро-кинематические параметры. В экс-периментальном виде определена оценка влияния различных факторов на вели-чину пятна контакта. Установлена зависимость между площадью пятна контакта и геометрическими параметрами зубчатых колес, входящих в зубчатую передачу.
Данное исследование может быть использовано при конструировании раз-личных типов ортогональных винтовых зубчатых передач с целью в значительной степени повысить их нагрузочную способность и долговечность.
