Introduction: In Cameroon, blood transfusion safety is a real public health problem. It is one of the African countries where screening for HBsAb is not systematic in blood donors, which can expose the beneficiaries of these donations to possible viral hepatitis B (VHB) infections. Methodology: We carry out a descriptive study at the Yaoundé Central Hospital blood bank during the period from August to October 2018. It was intended to determine the residual risk of transmission of VHB related to the presence of HBcAb in blood donors tested negative to HBsAg. The immunochromatographic technique was used for the detection of total HBcAb in blood donors tested negative for HBsAg, HCV, HIV and TPHA markers. The viral markers, HBsAg, HIV, HCVAb, and TPHA, were tested by ARCHITECT, an apparatus which uses the immunological principle of chemiluminescence. Results: Of the 148 donors registered in the study, we had 129 men and 19 women. We obtained an overall transmission risk of HBV related to the presence of HBcAb of 43.24%. This risk was 47.37% for family donors (p = 0.03999) and 27.3% for volunteers. No significant association was found between the sex of the participants (p = 0.3762), age (p = 0.7403), donor regularity (p = 0.4587) and HBcAb frequency. Concluson: In view of these results, the HBcAb remains very high in the blood donors tested HBsAg negative in Cameroon. To complete this study, we suggest the screening for viral DNA in donors who are tested HBsAg negative and HBcAb positive to eradicate this residual risk of HBV transmission through blood transfusion.

Published: September 2021

Introduction: Around 1.13 billion population and among them one in four men and one in five women are affected with this worldwide. In India, 20.6% of males and 20.9% of females were having hypertension. Orissa showed that 32% of men and 42% of women are affected with hypertension. Methodology: This descriptive comparative study focused on the gender based difference on the medication adherence among the hypertensive patients. A Self-structured questionnaire was used to collect the socio demographic profile and the Morisky Medication Adherence Scale used to collect the adherence to the patients. The sample size of this study was 93 females and 118 males selected from simple random sampling technique Results: Among the participants majority of the participants from the both group were 40- 60 years of age. The most of the male participants had a medium level of medication adherence (83%) and females had a low medication adherence level (34%) when comparing between the two genders. There is no significant difference (0.479) between the male and female medication adherence score. The study results showed that the female participants education and exercise status with the medication adherence had a significant association. Conclusion: The present study revealed that there is no gender based difference on the adherence of medication among the patients with high blood pressure. When considering the regular medication practice the males are better than the females

Background: Atherosclerosis is an important cause of cardiovascular mortality and morbidity in the world and its progression might be slowed in many people with appropriate lifestyle and drug interventions. Hence a lot of researches are targeting the atherosclerotic process and its mediators. Cystatin C is considered to be an active cysteine protease inhibitor found in all body fluids and expressed in all nucleated cells in the body and is a better marker of renal function when compared to creatinine. Elevated plasma levels of cystatin C is thought to be associated with increased risk of cardiovascular disease (CVD) and mortality in different populations. This may be due to the fact that it represents occult impaired renal function, which is associated with increased risk of CVD. However, in several studies, cystatin C has been associated with CVD even within normal ranges of eGFR. Aim: To evaluate the relation of the serum cystatin C level and atherosclerotic burden in coronary arteries Methods: Our study included 80 patients of both sexes with known or suspected ischemic heart disease who were candidates for coronary angiography. Their serum Cystatin C level was measured using ELISA technique and correlated with coronary atherosclerosis using Gensini score. Results: No association was found between coronary atherosclerosis severity and serum cystatin C level. There was also no difference in serum cystatin C level between patients presenting with acute coronary syndrome and those presenting with stable ischaemic heart disease. Conclusion: The relation between serum cystatin C level and coronary atherosclerosis is still unclear

Malignant hemopathies designate neoplasias of hematopoietic tissues, characterized by a disorder of the multiplication and differentiation of cells from one or more blood lines; Very few related studies are carried out in Africa due to diagnostic difficulties. We have carried out the present study to enrich the data on these pathologies. An analytical retrospective study was carried out in the hematology and medical oncology department of the Central Hospital of Yaoundé in Cameroon over 10 years, from January 1, 2008 to December 31, 2017. A technical sheet in which the epidemiological variables were noted, clinical, biological, therapeutic and evolutionary has been developed. Of the 167 files selected, the average age of the patients was 52 years +/- 16, with extremes of 21 and 87 years. Acute myeloid leukemias (AML) was more common in patients aged 45 to 54 (8 cases) and the disease affected more women than men at this age group (1H / 7F). Lymphoproliferative syndromes were the most common group of malignant hemopathies, accounting for 52.7% (88 patients). Non hodgkin lymphomas (NHL) were represented at all age groups with a male predominance. Patients with multiple myeloma clinically presented osteoarticular pain in 66.7% of cases. The chemotherapy protocols were varied according to the pathologies and their evolutionary stages. Toxic events were rare. Survival after one year was 9% for AML cases, 30% for CML cases. Few data being available on malignant hemopathies, this work allowed us to measure the importance of this group of pathologies in our context and to identify the clinical-biological profiles and the survival of the patients

To prevent excess morbidity and mortality of Covid-19, a prompt and accurate diagnosis is crucial. Antibody-based rapid diagnostic test (RDT) is a rapid, fairly reliable, and useful diagnostic testing solution for COVID-19. As a point-of-care test with fast turnaround time, the kit permits quick screening in hospitals to avoid the crowding of specimen collection. However, available RDTs kits have different sensitivity, specificity, and accuracy profiles due to antigen and antibody variability because of the sequence mutation of the SARS-CoV-2 gene. Therefore, it is strongly recommended to either re-measure the accuracy of a rapid test before using it in a different country or use tests developed based on local viral characteristics

Authors: Tembe Harka Raj
Published: September 2021

This research study focuses on the students’ perception on the use of mobile phones in EFL learning in the context of Nepal. It aims to investigate how the students are taking smart phones as a means for EFL learning in their educational experience. The study was carried out among the students of the bachelor level at Dhankuta Multiple Campus. It was largely informed by a phenomenological approach in order to examine the students’ experiences of using mobile phones in EFL learning. The semi- structured interview was held to collect the required data. Results indicate that all participants have positive attitudes on the use of mobile phones in learning English. However, they feel a few difficulties in understanding the text through the mobile phones. They expect supportive guidance and reliable network quality for effective EFL learning. Mobile phones can serve as a useful language learning tool if it is utilized properly for specific purposes. All curriculum developers, syllabus designer and policy makers should consider the space of mobile assisted English language learning in the present curriculum.
Essay Review: Evidence-Based Analysis of the COVID Pandemic
Authors: Bauer Henry
Published: September 2021

This short book suggests plausible answers to much of what has seemed inexplicable or unbelievable about what governments, the World Health Organization, and popular media have disseminated about the officially declared global pandemic.

The author is a recently graduated Swedish physician who recognized even during his training that many of the generally accepted shibboleths about medical matters are not evidence-based; are often, in fact, contrary to the available evidence.

Irrespective of his suggestions about COVID, several points in this book are important for everyone to know:

Modern medicine focuses on the handling of emergencies but says “extremely little about how to avoid chronic disease and maximize long term health” (p. 7).

More than half of the widely accepted recommendations about nutrition are nonsense, without any basis in solid evidence (p. 8): to eat more fruit, fish, vegetables, whole-grain cereals, and less salt, saturated fat, or meat.

Much purportedly scientific medical information stems from inappropriate use of surrogate endpoints and improper statistical analyses (pp. 34–39): The usual criterion for statistical significance (p ≤ 0.05) is arbitrary and very weak. The typical marketing ploy of citing relative rather than absolute risks is highly misleading (pp. 40–46).

How deadly is COVID?
More Sloppy Reasoning about Survival
Authors: Braude Stephen
Published: September 2021

In my writings on the evidence for postmortem survival. I’ve made no secret of the fact that I consider much of the literature on the subject to be very shabby, usually because the authors are empirically myopic or inferentially-challenged. That is, writers on survival notoriously ignore or treat very superficially relevant areas of research having their own extensive literatures (e.g., on dissociation, savantism, prodigies, gifted under-achievers, and language mastery), and too often they seem unable to formulate valid arguments. In Braude, 2003 I explored these deficiencies in great detail. Here, I’d like simply to comment on a particular class of confusions and a recent eruption of nonsequiturs.

Published: September 2021

In a veterinary medicine curriculum, students’ hands-on practice is essential but is still considered one of the major deficiencies in veterinary schools in Europe. After theoretical and basic practical training, students, under the control of experienced veterinarians (supervisors), monitored the reproductive cycle of embryo recipients by transrectal palpation and ultrasound. To evaluate the skills of students, the question “Has she ovulated?” was posed when a dominant follicle ≥ 35 mm was recorded in the previous day’s examination and a score of 1 or 0 was assigned in the case of a correct or incorrect answer (test palpation), respectively. Study 1 involved the retrospective evaluation of 3,509 test palpation records of 43 students (31 females, 12 males) and showed a statistically significant positive correlation between the number of test palpations performed and the proportion of correct answers. There was a statistically significant effect of the number of test palpations performed by each student, their gender, and the season on the correct answers. When performing > 50 test palpations, a statistical difference between gender was observed ( p < .05). Study 2 involved the prospective evaluation of 687 records on 52 standardbred or thoroughbred recipient mares collected from nine right-handed female students. The different mares, breed, occurrence of ovulation on the left or right ovary, and the presence of one or more large follicle(s) per ovary had no effect on the correct answers ( p > .05). Individual students’ performances were statistically different ( p < .05), ranging from 60% to 92%.

Las varices intraabdominales de la vena umbilical fetal son entidades poco comunes caracterizadas por la dilatación aneurismática focal. Representan aproximadamente 4% de las anomalías del cordón umbilical y se cree que son una anomalía del desarrollo más que una malformación congénita. Su importancia clínica aún no ha sido establecida claramente. El diagnóstico prenatal es realizado por ecografía convencional en la cual la lesión aparece como una estructura quística redonda o fusiforme dentro del abdomen fetal. Además, es útil para establecer el diámetro y la presencia de otras anomalías fetales asociadas. La evaluación Doppler permite identificar el tipo de flujo intralesional. El pronóstico perinatal es favorable cuando es identificada como un hallazgo aislado. No obstante, en aquellos casos asociados a otras alteraciones anatómicas / estructurales, la resultante fetal y neonatal es variable. Se presenta un caso de diagnóstico prenatal de varice intraabdominal de la vena umbilical fetal.
Concept of Universal Human Rights: Development and Evolution

Published: September 2021

The concept of human rights, having presumably universal meaning, usually derived from "Western' tradition. Although liberals of XVII and XVIII centuries consider the law of nature as a tool for it's protection starting from XIX century the rights (called the human rights by that time) considered as positive abilities to formulate one's personal, subjective preferences of individuals. That evolution must be taken into account both in researches and in political practices, carried out by representatives of different cultures, since the comprehension of an individual and a person as culturally justified serves as a besetting element. Thus the project of universal human rights must be the object of contemplation from the point of view of different cultures and the variety of preferences, oftentimes contradictory ideas, dominating in specific societies, rooted in their cultures, formed and developed over a long many of years. Indeed, both theoretical and practical concepts have huge impact for political being. Speaking not only about implications of specific legislative branches and governments to applications universal human rights standard, but also about creating such standard from different point of views in accordance with the idea of not competing with popular sovereignty.

COVID-19 cases increase at a high rate and become dangerous in recent months. As a consequence, some healthcare and research organizations are attempting to find an effective cure for the COVID-19 outbreak. Many natural products have been reported to have powerful activity against COVID-19 in recent research studies. The primary aim of this article is to establish natural bioactive compounds with suitable antiviral properties. Lui et al. have reported in their study that SARS-Cov-2 main protease is present in a crystalline structure known as a novel therapeutic drug target. It is important to inhibit SARS-Cov-2 main protease to stop the replication of viral proteins. In this study natural compounds were screened using molecular modeling techniques to investigate probable bioactive compounds that block SARS-Cov-2. From these studies many natural compounds were found to have the potential to interact with viral proteins and show inhibitory activity against COVID-19 main protease (Mpro) and these natural compounds were also compared to known antiviral drugs such as Saquinavir and Remdesivir. Besides that, additional research is needed before these potential leads can be developed into natural therapeutic agents against COVID-19 to fight the epidemic.

In the article the thermal characteristics of a copolymer of poly(ethylene glycol)fumarate with methacrylic acid were studied in a dynamic mode in a nitrogen atmosphere for the first time. A kinetic analysis of the thermal destruction process was carried out using three different data processing methods (Freeman-Carroll, Sharp-Wentworth, Achar). Thermodynamic characteristics were also calculated, namely the change in the Gibbs energy (∆G), enthalpy (∆H) and entropy of activation (∆S). The curves of thermogravimetric and differential thermogravimetric analysis of the copolymer were studied in a nitrogen atmosphere at a heating rate of 10 °C/min. The main stage of the copolymer decomposition was found to occur in a narrow temperature range, which is confirmed by a peak in the differential curve. Changes in the reaction rate of the copolymer were shown due to the decrease in the sample mass. It was shown that the results of kinetic analysis depend on the molecular structure of the compounds under study. The activation energies found by the Freeman-Carroll method have lower values, while the Achar and Sharp-Wentworth methods give the same results.

Some technological solutions contain valuable components and can become an additional source of rare-earth elements to satisfy the current production demands. This research provides the study on using a combination of polyacrylic acid hydrogel (hPAA) and hydrogel of poly-4-vinylpyridine (hP4VP) in different molar ratios for praseodymium ions sorption from its nitrate solution. The mutual activation of the hydrogels in an aqueous medium provides their transformation into a highly ionized state by the conformational and electrochemical changes in properties during their remote interaction. The electrochemical properties of solutions were studied by the methods of electrical conductivity, and pH measurements of the solutions. The research showed that the maximum activation of hydrogels was revealed within the molar ratio of hPAA:hP4VP equal to 1:5. Moreover, the total praseodymium ions sorption degree after 24 hours of sorption by individual hPAA and hP4VP was 54 % and 47 %, respectively, whereas the praseodymium ions sorption degree by the hPAA–hP4VP intergel system in the molar ratio 1:5 became 62 %. A slight increase in the sorption degree of praseodymium ions by the intergel system in comparison with individual hydrogels can be explained by the achievement of a higher ionization degree of hydrogels being activated in the hPAA–hP4VP interpolymer system by the remote interaction effect.

The copper-zinc manganites of LaMeIICuZnMnO6 (MeII — Mg, Ca, Sr, Ba) have been synthesized with the high-temperature interaction of alkaline earth metals carbonates with oxides of lanthanum (III), copper (II), zinc (II) and manganese (III). The synthesized polycrystalline copper-zinc manganites have been grinded on the Retsch vibration mill MM301 (Germany). As a result their nanostructured particles have been obtained. Their sizes have been determined using an electron microscope Mira3 LMU, Tescan. Methods of radiography determined that all synthesized nanostructured copper-zinc manganites crystallize in the cubic syngony with the following parameters of a lattice: LaMgCuZnMnO6 — а = 13.530.02 Å, Vo = 2476.810.06 Å3, Z = 4, Voelect.cell = 619.200.02 Å3, roent = 4.52; pick = 4.500.01 g/cm3; LaCaCuZnMnO6 — а = 13.690.02 Å, Vo = 2565.730.06 Å3, Z = 4, Voelect.cell. = 641.430.02 Å3, roent = 4.43; pick = 4.410.01 g/cm3; LaSrCuZnMnO6 — а = 13.910.02 Å, Vo = 2691.420.06 Å3, Z = 4, Voelect.cell = 672.850.02 Å3, roent = 4.99; pick. = 4.960.01 g/cm3; LaBaCuZnMnO6 — а = 14.550.02 Å, Vo = 3080.270.06 Å3, Z = 4, Voelect.cell = 770.070.02 Å3, roent = 4.95; pick = 4.940.01 g/cm3. The X-ray investigations demonstrated that the values of lattice parameters of the studied copper-zinc manganites have been increased from Mg to Ba. As a result of the investigations, these compounds can be included in Pm3m spatial group.

For the first time, double gadolinium tellurites of the composition GdMIITeO4.5 (MII — Sr, Ba) were synthesized by the solid-phase method. The solid-phase synthesis of samples was carried out from decrepitated gadolinium (III) and tellurium (IV) oxides, strontium, and barium carbonates according to the standard ceramic technology. The synthesis was carried out in the temperature range of 800-1100 °C. The samples obtained were confirmed by X-ray phase analysis. X-ray phase analysis was carried out on an Empyrean instrument in the XRDML Pananalitical format. The intensity of the diffraction maxima was estimated on a 100-point scale. X-ray diffraction patterns indexing of the powder of gadolinium tellurites — alkaline earth metals studied were carried out by the homology method. The reliability and correctness of the results of indexing the X-ray diffraction patterns are confirmed by the good agreement between the experimental and calculated values of the interplanar distances (d) and the agreement between the values of the X-ray and pycnometric densities. It was found that compounds GdSrTeO4.5 and GdBaTeO4.5 crystallize in the monoclinic system and have the unit cell parameters, namely GdSrTeO4.5 — a = 12.7610, b = 10.4289, c = 8.6235 Å, V° = 1141.83 Å3, β = 95.77°, Z = 5, ρrent. = 3.22, ρpikn. = (3.10±0.09) g/cm3; GdBaTeO4.5 — a = 15.7272, b = 15.8351, c = 7.1393 Å, V° = 1769.72 Å3, β = 95.53°, Z = 8, ρrent = 3.71, ρpick = (3.61±0.10) g/cm3. Using the Landiya method, the standard heat capacities of the compounds were estimated from the calculated values of the standard entropies, and the temperature dependences of the heat capacities of the gadolinium tellurites synthesized were determined in the temperature range of 298–850 K.

The inhibition effect of series of thiadiazole derivatives against the corrosion of mild steel in 15 % HCl was studied by weight-loss method and electrochemical measurements. The experiments were performed on steel St3 at 293 K, the exposure time of the samples in solution for weight-loss measurements was 24 h. Potentiodynamic polarization curves were obtained in a typical three electrode cell with the help of electrochemical measuring complex SOLARTRON 1280 C. A scan rate was 1 mV⋅s-1 and a measurement point was taken every 0.2 s. 2-aminothiazole, 5-amino-1,3,4-thiadiazole-2-thiol, 2-amino-1,3,4-thiadiazole, 2-amino-5-(furan-2-yl)- 1,3,4-thiadiazole, 1,3,4-thiadiazole-2-ylamide of acetic acid were studied as potential inhibitors. The maximal inhibition efficiency was obtained at concentration 0.10-0.20 g⋅L−1. The best result was demonstrated by 5-amino-1,3,4-thiadiazole-2-thiol (inhibition effect was more than 90 %). The minimal inhibition effect had 1,3,4-thiadiazole-2-ylamide acetic acid. The corrosion inhibition effect calculated from data of the corrosion current density and from the weight-loss measurements were in sufficiently good agreement. The effective activation energy of the corrosion of St3 increased significantly due the presence of the inhibitors (from 3.3 to 94.8 kJ⋅mol-1). The results point to promising of investigating of series of thiadiazole derivatives and inhibitory compositions based on thiadiazole as potential acid corrosion inhibitors.

Fresh material of the inadequately described male of Gymnophora lapidicola (Bezzi, 1922), which is flightless in both sexes, has allowed illustration of critical details, including correction of an error in the description of the female by Ghidini (1934). The possibility that populations on different mountains may have diverged to form separate subspecies or sibling species is raised.

Liver disfunction is characterized by increased levels of SGOT and SGPT. The mechanism of liver disfunction by anti-tuberculosis drug (ATD) is not yet clearly known, but several research mention the occurrence of hepatotoxicity which caused by direct effect or through the complex production of drug enzyme which have consequences in cell disfunction as well as membrane disfunction. Hepatotoxicity due to ATD does not occur in each patient, but it could cause liver injury. research objective to find out the description of examination of SGOT and SGPT levels in patients of pulmonary tuberculosis. The research type was descriptive using medical records data and laboratory data of RSUP patients of pulmonary TB in January-March 2020.

Plant Macro-Remains and Traces of Leaves from Virje and Hlebine
Authors: Šoštarić Renata , Vilović Tihana
Published: September 2021

During years of archaeological research of mediaeval settlements and Late Antique and mediaeval smelting workshops in the area of Podravina, archaeobotanical samples were collected from the following sites: Hlebine – Dedanovice (H-Ded), Hlebine – Velike Hlebine (H-VH), Virje – Volarski breg (V-VB), and Virje – Sušine (V-Suš). They include fruits, seeds, and leaf imprints/remains. Despite the relatively large number of samples, only a small number of finds was found. It mostly consisted of non-carbonized plant remains from various species of weed and ruderal plants, that most likely represent recent contamination. Of the few carbonized finds, the most significant are the remains of cereals preserved in a rather poor condition: proso millet (Panicum miliaceum), foxtail millet (Setaria italica), spelt (Triticum spelta) and naked wheat (Triticum aestivum group), and fragmented and damaged remains of large-grain cereals (Cerealia). Due to the small number of archaeobotanical finds originating from the archaeological formations dated into the wide period from the Late Iron Age to the Early Modern Age, nothing can be said in more detail about the diet, agriculture, or other activities of the population of Virje and Hlebine during individual archaeological and historical periods. In general, it can be concluded, taking into account other sites from the area of Podravina (Torčec and Virovitica Kiškorija jug), that different types of cereals, such as wheat/spelt (Triticum), barley (Hordeum vulgare) and proso millet (Panicum miliaceum), formed the basis of the daily diet of the population of Podravina throughout various investigated periods, probably in combination with legumes, and that they were grown in the vicinity of the settlement. Finds of grapevine (Vitis vinifera) suggest that wine also had a significant place in the past of Podravina. At the position of Virje – Sušine, in Trench S-7, SU 314, a smelting furnace hearth wall fragment with a leaf imprint was found. The imprint most probably belongs to black alder (Alnus glutinosa) and dates from the period of Late Antiquity (late 4th/early 5th century). At the position of Hlebine – Velike Hlebine, in Trench S-2, SU 102, a partially fossilized leaf was found in the slag from the period of the transition from Late Antiquity to the Early Middle Ages. Since the sample was too small, it could not be identified with certainty.
Methodological Framework for Experiments Related to Bloomery Iron Production Procedures: Ore Preparation and Smelting
Authors: Karavidović Tena
Published: September 2021

Systematic, well-designed experimental research and standardized documentation is a starting point for explaining the outcome of experiments and comparative analyses, whether within single experimental research or a wider frame of comparison with other research. This contribution presents a sequence of research procedures that served as a basis for the design and implementation of experiments related to bloomery iron production procedures. A proposal for the method of documentation is made with the aim of combining all general functional parameters relevant to the procedures of ore preparation and direct process of reduction in the reconstruction of a smelting furnace, based on personal experiences and the current state of experimental research related to iron production. The objective is to give a structured basic template of main parameters that should be recorded and reported when performing experiments related to the mentioned procedures. The hope is to bring forward a layout that should be upgraded and further developed based on specific research questions one could have.
