Published: January 2024

Socio-cultural factors, attitude and belief have been identified as major factors of diseases compliance and are germane to preventing COVID-19 because of their direct influence in the preventive process of COVID-19. There is dearth of data concerning these variables in the spread of COVID-19. This study examined the influence of socio-cultural factors, attitude, and belief in the prevention of COVID-19 in Abuja, Nigeria and the pivotal role of health education in order to ascertain how the listed factors affect compliance of Abuja residents in preventing the spread of the disease. A cross-sectional survey design, and 338 participants selected using snowball sampling technique. A self-structured validated questionnaire (coefficient reliability 8.0) administered electronically for three weeks (June 2020) was used for data collection. Data analyzed using frequency counts, percentages and mean for demographic data. Hypotheses tested using inferential statistics of regression, T-test, ANOVA and Schefft’s Post Hoc at 0.05 significance level. Attitude and belief were significant predictors of participants’ preventive measures, F (2, 335) = 6.373 where p < 0.05; indicating that increase in attitude and belief of the participants led to taking more precautionary measures of COVID-19. Family type of the participants influenced compliance to COVID-19 (T (336) = -3.109 where p < 0.05). Other socio-cultural factors: occupation, education, ethnicity, and income influenced participants’ compliance to COVID-19 prevention (p < 0.05). Religion and neighborhood did not influence the participants’ compliance to COVID-19 prevention (p > 0.05). Health education is a veritable tool to ameliorate socio-cultural factors influencing compliance to COVID-19 and has a pivotal role to play in preventing the spread of COVID-19. It should be positioned proactively to reduce the impact of the influence of socio-cultural factors on the spread of COVID-19. Similar studies should be carried out in other parts of Nigeria for comparison.

Authors: Yakıştıran Betül , Çelen Şevki , Aksakal Uslu Ayşegül 
Published: January 2024

Background: Hemangioma is one of the umbilical cord anomalies and it is arising from the remnants of embryo hemangioblasts. It is associated with increased perinatal morbidity and mortality.
Case report: We describe an umbilical cord hemangioma that was identified in antenatal period. The patient was referred to our hospital for further evaluation of omphalocele that was noticed at gestational age of 29 week. The mass, measured 80*75*50 mm diameter, was surrounded by edema of the Wharton jelly. Color Doppler imaging revealed arterial and venous flow within the mass. The neoplasm was composed of organized and non-organized capillary vessels within the myxoid stroma. Neoplasm was covered with squamous epithelium focally but the epithelium was widely eroded. The immunohistochemical examination positive staining was obtained for vimentin, desmin, CD34 and SMA.
Conclusion: Umbilical cord anomalies are rare. Early detection and close follow-up can reduce the risk of perinatal morbidity and mortality.
El debate parlamentario sobre la destitución de Dilma Rousseff: la palabra de las senadoras brasileñas
Authors: De Barros Antonio Texeira , Cavalhero Myriam Violeta 
Published: January 2024

Objetivo/contexto: el estudio tuvo como objetivo analizar el debate entre las senadoras brasileñas durante el juicio político a Dilma Rousseff, en 2016. Metodología: se utilizó el análisis del discurso sobre la principal cuestión examinada: ¿cómo fue el debate entre las senadoras, considerando el espectro ideológico-partidario y la posición con respecto a la destitución (a favor o en contra)? El análisis presenta un perfil político-ideológico de las senadoras, los argumentos que utilizaron en el debate, además de los diferentes usos de la defensa de la democracia. Conclusiones: las senadoras de izquierda fueron más asiduas, además de repetir con mayor frecuencia sus argumentos, con el objetivo de aumentar la visibilidad discursiva. Asimismo, abordaron la inexistencia de un delito de responsabilidad, condición para el inicio de un proceso de juicio político. Las senadoras de derecha y centro, por su parte, recurrieron a modelos retóricos para reiterar que la entonces presidente de la República ya no estaba en condiciones de mantener una base parlamentaria que sustentara su gobierno. Las senadoras de este grupo también afirmaron que las investigaciones demostraron el uso de esquemas para disfrazar irresponsablemente las cuentas públicas, exclusivamente con miras a la reelección de Rousseff. Originalidad: es importante resaltar el hecho de que se trata de un análisis del impedimento de una mujer en el cargo de presidente de la República, desde la perspectiva femenina del órgano parlamentario del Senado, institución encargada de juzgar el proceso de juicio político.
Synthesis and Thio-Functionalization of Metal Organic Frameworks of Isonicotinate Ligands and their Application for Fluorescein Removal from Aqueous Solution
Authors: Ajayi Samson Abidemi 
Published: January 2024

Mechanochemical syntheses of four (4) know metal organic frameworks (MOFs) were obtained by grinding stoichiometric amounts of metal salts [Zn (II) and Cu (II)] and corresponding carboxylate ligands [Fumaric and Isonicotinic acids] in a mortar with a pestle. Also, Solvent-based syntheses of MOFs were carried out with the reaction of metal salts and each carboxylate ligand by mixing in the presence of solvents. The compounds were characterized by the comparison of melting point, elemental analysis, FT-IR spectroscopy and XRPD results with those of the free ligands and literature. The analytical and spectroscopic data of the compounds prepared via the two different methods gave the expected product.
The presence of coordinatively unsaturated metal centers in the synthesized MOFs provides an accessible way to selectively functionalize them through coordination bonds. In this work, thiol-functionalization of MOFs were described by choosing six well known MOFs in which three (3) are Zn-based while the other three (3) are Cu-based MOF, by a facile coordination based postsynthetic strategy. The obtained thiol-functionalized MOFs were characterized by powder X-ray diffraction, CHN and infrared spectroscopy. The analytical and spectroscopic data of the unmodified and modified compound were different.
A series of [Cu (Ina)2] samples stoichiometrically decorated with thiol groups has been prepared through coordination bonding of coordinatively unsaturated metal centers with –SH group in thioglycolic acid. [Cu (Ina)2]. H2O and [Cu(Ina)2]-TH were investigated for the adsorptive removal of fluorescein from aqueous solution. The parameters that affect the dye sorption such as contact time, solution pH, initial fluorescein concentration and temperature, have been investigated and optimized conditions determined at PH of 7.8. Dubinin–Radushkevich Equilibrium isotherm studies were used to evaluate the maximum sorption capacity of MOFs and experimental results showed that the removal efficiency decreases in the order of [Cu(Ina)2]-TH > [Cu(Ina)2].H2O both in adsorption rate and adsorption capacity. The Langmuir, Freundlich, Temkin and Dubinin Radushkevich models have been applied and the data correlate well with Dubinin Radushkevich model. The adsorption mechanism may be explained with a simple electrostatic interaction and π- π interaction. Finally, it can be suggested that modification of MOFs can be use to improve their adsorption capacity and rate, making them a better adsorbent to remove emerging dyes contaminants from waste water.

Published: January 2024

Renewable energy is the most promising energy-saving and environmentally friendly option. The concentrating type solar collector like parabolic trough collectors can be utilized for solar thermal energy collection due to low cost and high-temperature output. The paper is an experimental study of a solar parabolic trough collector with manual sun tracking. A parabolic trough with an area of 2.5´1.75 m² was constructed for the present study. A highly polished aluminum sheet for concentrating the reflecting sunlight to the focal line contains the receiver tube. The parabolic trough was tracked at regular interval of one hour concerning the sun position and focused the sunlight into the receiver tube to ensure sound performance. Water is used as a working fluid inside the receiver tube, and experiments were done with three different mass flow rates of 0.0072,0.0112 and 0.0158 kg/s. Two heat-collecting elements, such as a stainless-steel receiver tube and a glass-coated copper receiver tube, were tested with a parabolic trough. The performance was analyzed based on the difference in the inlet and outlet temperature of the working fluid at the ends of the receiver tubes of the parabolic trough. The instantaneous efficiency of the parabolic trough with two different materials of receiver tube at three different flow rates were evaluated. The results showed that the glass coated copper tube surpassed in performance compared with stainless steel receiver tubes. The instantaneous efficiency of the glass coated copper tube is found to be 71.17% at a flow rate of 0.0158 kg/s which was significantly high when compared with that of the stainless-steel receiver tube. The glass coated copper tube prevents the convective heat transfer loss and thereby increases the efficiency. The experiment shows that the performance of the parabolic trough solar collector strongly depends upon solar light tracking and the focal line containing the receiver tube.

A study on “Synthesis, Characterization and Impact of Nano-urea on Growth and Yield of Wheat in Inceptisol” was conducted at Division of Soil Science, College of Agriculture, Pune during rabi 2021. The object of this experiment is to synthesize and characterize nano-urea at post graduate laboratory of Soil Science, College of Agriculture, Pune and which is named as COAP (College of Agriculture, Pune). Nano-urea was synthesized from granular conventional urea and characterised for size of nano particles by using scanning electron microscope. The experiment consisted of twenty one combinations of treatment based on 3 levels of recommended doses of nitrogen (0, 50, 75%) and six nitrogen levels for foliar sprays and water spray as a control which was replicated twice in factorial completely randomized Design (FCRD). The foliar sprays of nitrogen consisted of four levels of COAP nano-urea @ 50, 100, 150 and 200 ppm, IFFCO nano-urea @ 160 ppm and conventional urea @ 10,000 ppm applied at 30 and 50 DAS.
It could be revealed that average size of COAP (22.419 nm) and IFFCO (22.773 nm) nano-urea was almost same. Results revealed that conjoint application of 75% nitrogen along with two foliar sprays of conventional urea @10,000 ppm, COAP nano-urea @ 200 ppm and IFFCO nano-urea @ 160 ppm taken at 30 and 50 DAS for wheat recorded significantly higher periodical plant height and leaf area at 35 and 55 DAS. Significantly higher plant height was reported with combine application of 75% RDN along with two foliar sprays of urea @ 10,000 ppm (76.83 cm) which was statistically at par with nano-urea of IIFCO (76.20 cm) and COAP (74.20 cm) than rest of the treatment at 55 DAS. In case of leaf area, application of 75% RDN along with two foliar sprays of either conventional urea @ 10,000 ppm, IFFCO nano- urea @ 160 ppm and COAP nano-urea @ 200 ppm at 35 and 55 DAS. Application of 75% recommended dose of nitrogen along with two foliar sprays of 10,000 ppm conventional urea recorded significantly higher grain (45 g pot-1) and straw yield (65.39 g pot-1) of wheat which was found to be significantly at par with 75% RDN + IFFCO nano-urea @160 ppm (44.91 and 62.87 g pot-1) and 75% RDN + COAP nano-urea @ 200 ppm (44.83 and 60.66 g pot-1).

Published: January 2024

Background: The COVID-19 pandemic has aroused interest in understanding the immunological mechanisms involved in the response to SARS-CoV-2. The lectin pathway stands out in this scenario, since understanding the activation of this pathway during COVID-19 infection can provide valuable information about correlated immunological mechanisms, especially in the uncontrolled inflammatory response of severe cases.
Aim: Thus, the objective was to synthesize the available information on the role of the lectin pathway in the activation of the complement system and its relevance in the immune response and pathogenesis of COVID-19 infection.
Methods: This is a systematic review carried out according to the PRISMA guidelines using the PICOS strategy. The quality of the studies and risk of bias were evaluated using the Checklist Hawker. After the analysis, 11 pertinent studies with the objectives of this study were included.
Results: Patients with COVID-19 had high levels of mannose-binding lectin recognition protein (MBL), especially those with thromboembolic complications. MBL reduction due to certain genotypes (BB or AB) was associated with a more severe form of the disease. The interaction between VL recognition proteins and SARS-CoV-2 virus proteins suggests the activation of the complement system through this pathway. The interaction of SARS-CoV-2 protein N with the VL activator potentiates complement activation. There is a correlation between the genetic polymorphisms in the MBL2 gene and the expression of MBL in the tissues during infection.
Conclusion: Although some studies have not found consistent correlations between complement markers and disease severity, it is consensus that complement system activation is present in patients with COVID-19, and high levels of activation products are associated with more severe forms of the disease, suggesting that inadequate regulation of the complement system may contribute to the uncontrolled inflammatory response and serious complications of COVID-19. Future investigations should explore the specific mechanisms related to the activation of the complement system through the lectin pathway in SARS-CoV-2 infection, thus providing valuable insights for the development of more effective therapeutic strategies against COVID-19.
Giant Multicyst Neck Lymphangioma in Adult with Single Session Ethanol Ablation Treatment: Rare Case Report
Authors: Sentoso Joko Wibowo , Yarsa Kristanto Yuli 
Published: January 2024

Introduction: Neck lymphangioma is a benign congenital malformation that occurs frequently in children, and is rare in adults. They are usually found in the head and neck region and are often considered a metastatic lesion rather than a primary neoplasia. Most lymphangiomas are acquired at birth which is about 60%, and by the age of 2 years about 80% to 90% are present. The most common location of the abnormality is the submandibular region followed by the parotid gland.
Case Presentation: A 22-year-old man with complaints of lumps on the right side of the neck that has been getting bigger since 5 months ago. The lump initially appeared the size of a tennis ball, then quickly grew to the size of a watermelon within a month. Physical examination revealed a mass in the right colli region, cystic, fixed, multiple masses of varying size. The core biopsy examination showed the results of lymphangioma. The patient was treated with Ethanol Ablation.
Discussion: Neck lymphangiomas that are clinically more circumscribed than cavernous lymphangioma. On physical examination, they are soft, with varying sizes and shapes, and will typically grow if not surgically excised. MRI can be useful in determining the extent of anatomical involvement of cystic or cavernous lymphangiomas. Treatment of neck lymphoma is mainly surgical resection. Resection surgery can be associated with complications like lymphatic leaks, fistula formation, chronic wounds, neck on account of mucosal oedema, enlargement of internal lymphangiomas, and loss of neural innervation to the pharynx or tongue. Radiofrequency ablation is a safe, viable alternative and effective debulking treatment of neck lymphangioma.
Conclusion: We recommend ethanol ablation is a safe, viable alternative and effective debulking treatment of neck lymphangioma and thermal damage to surrounding tissues. This paper constitutes the first report of successful treatment of airway obstruction due to neck lymphangioma.
