Authors: Yonphan Saksit , Seithtanabutara V. , Wongwuttanasatian Tanakorn
Published: August 2022

Dye-sensitizer is heart of dye-sensitized solar cell which is an electron donor when receiving irradiation on the surface. Dye can be classified as synthesized dye or natural dye. Natural dye can be obtained colourfully from various plants such as tomato, carrot, grapes, chili, and so on. In this work, three selected plants which are locally available were chosen for three different colours. Green colour was extracted from leaves of Tiliacoratriandra (Ya-nang). Red colour was from flower of Hibiscus sabdariffa (Rosella), and purple colour was from fruits of Morus alba (Mulberry). They were dried and ground into powder and their colour was extracted using 95%-ethanol. The concentrations of solution were 5, 10, and 20 g of powder per 200 ml for solvent extraction of each colour. These three colours were tested for absorbance index indicating ability of light absorption. The absorbance index curves showed that Ya-nang in green colour gave the best absorbance index having several peaks at 458 and 675 nm wavelengths for the 20 g/200 ml solution. While Rosella in red colour showed the peak at 534 nm wavelength and Mulberry in purple colour gave peak at 666 nm wavelength. The characteristics from the absorbance index curves also revealed the type of colour pigment in the dye. It was found that Ya-nang in green dye, Rosella in red dye and Mulberry in purple dye contained “Chlorophyll”, “Anthocyanin” and “Betacyanin” pigments respectively. Moreover, the area under the curves obviously indicated that the area of the green colour from Ya-nang was higher than those of Rosella and Mulberry. This implied that Ya-nang had higher potential to be dye-sensitizer and would give better dye sensitized solar performance compared with Rosella and Mulberry.

Published: August 2022

The research on the nanofluid as an alternative transformer oil has been widely attracted the concern of many researchers as the effectiveness as insulation and cooling agent of the existing transformer oil is not achieved satisfactory to accommodate the rising demand of high voltage rate. In this study, nanofluid with a nanomaterial, Carbon Nanotube (CNT), with and without Polyvinylpyrrolidone (PVP) has been formulated, and their AC breakdown voltage of the mineral oil (MO) according to IEC 60156 standard has been characterized. The concentration of CNT study is 0.005, 0.01, 0.015 and 0.02 g/L. It is found that the optimum concentration in nanofluids without PVP is 0.005g/L of nanofluids concentration with the highest breakdown voltage 53.52. In comparison, the highest breakdown voltage for nanofluids with PVP is 33.4kV at 0.01g/L. The existence of PVP in the nanofluids seems not significantly affect the dielectric performance of the degradation of the nanofluid from 5% to 43%. Hence, nanofluids with CNT addition are proofed as a good additive in insulation oil for future transformer applications.

Background: Hospital admissions with diabetes-related complications are on the rise in Sri Lanka. We aimed to study indications for hospital admissions and the prevalence of micro, macrovascular and non-vascular comorbidities in patients with diabetes mellitus admitted to a medical unit in a tertiary care hospital. Methods: A hospital-based, cross-sectional study was carried out in Teaching Hospital Karapitiya over six months. Four hundred in-ward patients with diabetes were studied. Evidence of diabetes nephropathy, nonvascular co-morbidities and indication for admission were extracted from medical records using a pretested data extraction form. Screening for Diabetic peripheral neuropathy (DPN), and diabetic retinopathy (DR) were carried out using standard protocols. Results: The highest number of admissions (142) were due to infections of which 52.8 % were females. One-third (33.8%) of the patients had previous admissions during the past year with a significant female preponderance (66%). DPN and DR were detected in 55.4% and 52.9% respectively with a significant proportion of them being females. Diabetic nephropathy was diagnosed in 27.9%. Nearly half (47.3%) of the sample was on treatment for hypertension and 39.4% were on statins. Evidence of previous myocardial infarction was significantly higher among the females compared to males (72.8% vs. 27. 2%). Conclusions: Infections were the most frequent indication for hospital admission among diabetic patients. DPN and DR are significantly higher among females than males. Use of statins for dyslipidaemia is suboptimal among the admitted patients.

Published: August 2022

Background: Anaemia in older adults is a common medical problem but it is often not evaluated as a sole clinical entity and its importance is undermined. The gravity of anaemia in older adults and its impact on other diseases is not well known in Sri Lanka. Methods: This was a cross-sectional descriptive study where data was extracted retrospectively from the database and clinical records of patients who were referred to the haematology unit of Teaching Hospital Jaffna, Sri Lanka for the evaluation of anaemia, from September 2020 to February 2021. The common types of anaemia, their severity, aetiological classifications and association with other diseases were analysed. Results: A total of 1121 medical records of patients above 60 years were analysed during the study period. The main source of referrals was from medical wards. The female to male ratio was 51.2:48.8.The majority belonged to the age group of 60-69 years. Two-third of the patients had normocytic anaemia (70.3%) followed by microcytic (23.7%) and macrocytic anaemia (6.0%). A moderate degree of anaemia was seen commonly, but 28.3% were found to have severe anaemia. Aetiological classification revealed anaemia of chronic disease as the commonest type of anaemia in older adults accounting for 37% of the study sample, followed by multifactorial aetiology and iron deficiency anaemia. Common chronic diseases identified along with anaemia were diabetes, hypertension, ischaemic heart disease and chronic kidney disease. Conclusions: Normocytic anaemia was the commonest type identified and the majority were of a moderate degree. Though the commonest aetiological cause identified is anaemia of chronic disease, there was a considerable percentage of multifactorial causes indicating the need to be on the lookout for other possibilities. Identifying the prevalence of anaemia in all hospitalised older adult patients in the local setting, the causes and the impact on chronic and acute illnesses will immensely help in the management of older adult patients and improve their quality of life.

Published: August 2022

E-learning is a method of delivering education via electronic media, typically using the internet. E-Learning contributes to conventional teaching methods and provides many advantages to society and citizens. Even if it facilitates fast learning at low cost, provide more access to learning platforms and has clear accountability for all participants in the learning systems, the problem is still a majority of students are demanding the interaction, attention and the quality of virtual education which they achieve from the traditional learning. Effectiveness in e-learning with reference to the learner is measured as whether the learner could meet the learning goals while learning online. Since traditional education couldn’t be continued, it was very important to find the significance of e-learning, the challenges students face using virtual platforms, and the factors that influence effectiveness of virtual education. While the literature reveals the factors that influence the effectiveness of e-learning, the study discovered the variables influencing the efficacy of e-learning initiative in the senior secondary education in a factual way using descriptive survey method involving hypothesis test to evaluate how contemporary information technology can develop a successful asynchronous system of education. The data were collected through an online survey which covered the private schools in Colombo, Sri Lanka, that follow the local curriculum set up by the Ministry of Education in local language mediums of Sinhala, Tamil or English. The conclusion is based on the 369 responses received from the senior secondary level students and the study discovered that IT Infrastructure, Instructor Competencies, Perceived Ease of Use and Perceived Usefulness have a significance impact on Effectiveness of e-learning.

Authors: Silva Dilshan , Wanninayake W. M. C. B.
Published: August 2022

Most significantly, in apparel manufacturing, the introduction of sewing automation with strategic intention has improved productivity largely. Automation in apparel manufacturing was primarily considered as critical productivity enhancement approach and it can be argued that success of sewing automation may depend on astute employee engagement. Therefore, this paper intends to outline how employee engagement benefits sewing operation automation in the apparel industry to realize its successful outcomes. Thus, to conduct the research study on this topic, the researchers considered manual sewing operation at ABC Company, which was selected due to its low productivity and high rework leading to high costs. The outcomes of the research study are generalizable towards the apparel industry in Sri Lanka. Having conducted a comprehensive review of the literature and empirical studies; Employee Engagement, Employee Competency, Employee Motivation and Top Management Commitment have been selected as the independent variables and Sewing Automation Success is presented as the dependent variable. Results show that, developed conceptual model is accepted and a strong positive relationship between all the independent variables and the dependent variable (Sewing Automation Success) is established. The researchers used quantitative method and data collection by deploying a questionnaire to 196 operators, the result has been analyzed using SPSS version 27. The findings suggest a significant impact of employee engagement towards sewing automation. Recommendations stress that top management should focus on employee engagement providing career prospects to optimize their potential.

Authors: Fernando M. B. V. L. , Jeewanthi H. A. C.
Published: August 2022

The purpose of this study is to synthesize the impact of integrated reporting on the firm value of licensed banks and finance companies in Sri Lanka. This paper develops an informative outcome, covering 20 licensed banks and finance companies for the period from 2015 to 2020. The quantitative approach was employed to generate a multi-dimensional perspective on integrated reporting and firm value. The integrated reporting was measured using content analysis with the support of an integrated reporting index and, the firm value was measured by Tobin’s Q and market to book ratio. The study results revealed that integrated reporting has a significant negative relationship with firm value. As an emerging voluntary disclosure requirement, Sri Lankan licensed banks and finance companies showed a strong motive to follow the International Integrated Reporting Framework in their integrated reporting disclosures. However, Sri Lankan banks and finance companies have failed to gain the supreme benefits of integrated reporting yet. Even though, there are a few studies regarding integrated reporting and firm value, this study becomes one of the dominant studies which strive to explore the impact of integrated reporting on firm value using market-based performance indicators to measure firm value concerning Sri Lanka. Moreover, this study used a self-constructed scoring index to measure integrated reporting in Sri Lanka based on literature. The findings facilitate the practitioners and policymakers about rethinking and revisiting the adoption and the use of integrated reporting effectively.
Determinants of Environmental Management Accounting Practices: A Comparative Study between Listed Companies and Small and Medium Enterprises in Sri Lanka
Authors: Malavige T. , Wijesinghe B. A. C. H.
Published: August 2022

The purpose of this research is to identify the determinants of Environmental Management Accounting (EMA) practices of the Public Listed Companies (PLCs) and Small and Medium Enterprises (SMEs) in Sri Lanka. Using a self-administered questionnaire survey, primary data were collected from 33 PLCs and 40 SMEs in Sri Lanka. Findings imply that environmental laws, shareholder perception, consumer perception, competitor perception, staff motivation, and pressure from environmental groups are the significant determinants of EMA adoption in PLCs and SMEs. However, EMA implementation by PLCs and SMEs is hindered by unions and financial institutions. In SMEs, resource constraints and resistance to change are the main impediments, whereas financial and resource constraints are the main obstacles to adopting EMA practices in PLCs. SMEs believe that EMA practices reduce environmental damage, increase ecological sustainability, and improve the firm's reputation. Moreover, most PLCs believe that implementing EMA practices reduces pollution, lowers costs, improves environmental stewardship, and improves the firm's reputation. This study updates and extends on prior survey-based research on EMA comparing PLCs and SMEs. The study can help SME owners and PLC management comprehend the benefits of EMA while green-friendly stock investments will be encouraged.
IL-27 Promotes Intestinal Barrier Integrity following Ethanol Intoxication and Burn Injury
Authors: Luck Marisa E , Li Xiaoling , Herrnreiter Caroline J , Cannon Abigail R , Choudhry Mashkoor A
Published: August 2022

Alcohol intoxication combined with burn injury can lead to life-threatening complications, including sepsis, multiple organ failure, and death. After an acute burn, the gastrointestinal system becomes hypoxic because of fluid loss and reduction of intestinal blood flow. This can cause perturbations in the intestinal epithelial barrier, immune function, and the composition of the gut microbiome. Increased gut permeability leads to proinflammatory signaling, contributing to further damage to the intestinal barrier. Recent studies have suggested that IL-27 plays an anti-inflammatory role, which may be beneficial in intestinal barrier repair. Therefore, in this study, we examined the effect of ethanol and burn injury on IL-27 in the small intestine, as well as the potential beneficial role of IL-27 in restoring the intestinal barrier after intoxication and burn. Male C57BL/6 mice were gavaged with 2.9 g/kg ethanol before receiving a ∼12.5% total body surface area scald burn with or without rIL-27 in resuscitation fluid. Our results demonstrate that IL-27–producing cells are reduced in the small intestine after injury. When IL-27 is supplemented in resuscitation fluid, we were able to restore intestinal barrier integrity and transit, mediated through increased intestinal epithelial cell proliferation, reduced inflammatory cytokines, and increased anti-inflammatory cytokine IL-10. We also observed increased gene expression of tight junction proteins. These findings suggest that IL-27 may be a contributor to maintaining proper intestinal barrier function after injury through multiple mechanisms, including preventing excess inflammation and promoting intestinal epithelial cell proliferation and tight junction integrity.

Authors: Zaki Rania G.E. , Gharieb Hesham M. , Othman Ihab S.
Published: August 2022

Aim of the study

Measurement of the mean angle Kappa pre-keratorefractive and post-keratorefractive surgery utilizing Orbscan 3.

Patients and methods

This retrospective study was conducted on patients who had refractive surgeries, group A included patients who underwent Lasik and group B included patients who underwent Photo Refractive Keratectomy (PRK). Mean age from 18 to 45 years. Preoperative, 1-week, and 1-month postoperative assessments included detailed ocular examination, slit-scanning topography done by Orbscan 3, and total ocular aberrations by Zywave 3 were done.

Results

The study comprised 146 eyes of 75 individuals. Preoperative data demonstrated that angle Kappa mean in Lasik group (group A) was 2.38±1.54 at 147.05±96.94, in PRK group (group B) was 2.31±1.17 at 137.67±85.7. Paired mean differences of the two groups between preoperative data and 1-week postoperative show no statistically significant difference in central corneal thickness (CCT) nor angle Kappa values. Paired mean differences of the two groups between preoperative data and 1-month postoperative show no statistically significant difference regarding CCT nor angle Kappa values. Preoperative, 1-week postoperative, and 1-month postoperative correlation of angle Kappa to refractive error, spherical equivalent, average K-reading, CCT and axial length, showed that both groups had a positive correlation with axial length.

Conclusion

Keratorefractive surgeries do not affect angle Kappa or its intercept measurements.

Authors: Mostafa Mohamed A. , El-Shayeb Ashraf A.-H. , El-Shahed Ahmed F.
Published: August 2022

Aim

To evaluate the visual outcome of implantable phakic contact lens (IPCL) in high myopia.

Setting

Al-Mashreq Eye Center, Cairo, Egypt.

Patients and methods

Thirty eyes of 17 patients underwent surgery to correct high myopia using IPCL (Care Group-India) with a central hole (V2.0). Visual acuity, spherical equivalent, and intraocular pressure (IOP) were evaluated 6 months postoperatively. Anterior chamber parameters Anterior chamber volume (ACV), Anterior chamber depth (ACD), Anterior chamber angle width (ACAW) were measured using Pentacam.

Results

After 6 months, spherical equivalent decreased from −14.19±4.2 to −0.18±0.66 D, all cases were within ±1.00 D of intended correction. Best corrected visual acuity (BCVA) remained unchanged in 13% of cases, 13% gained one line, and 74% gained two or more lines. ACV, ACD, and ACAW decreased from 189.77±20.19 mm3, 3.15±0.27 mm, and 37.31±5.63° to 131.4±14.01 mm3, 3.05±0.29 mm, and 23.94±4.81°, respectively. Changes in IOP between preoperative and 6 months postoperatively were statistically insignificant.

Conclusion

IPCL is a safe, effective, and predictable surgery to correct high myopia. Most cases gained one or more lines of BCVA. Reduction of ACV did not induce IOP rise during 6 months of follow-up.

Published: August 2022

Lipomatous hypertrophy of the interatrial septum (LHIS) is a histologically benign cardiac lesion that is defined by excessive fat accumulation in the area of the interatrial septum (IAS) that does not include the fossa ovalis. Another unusual illness is lipomatosis, which is defined as a broad overgrowth of mature adipose tissue that involves a large portion of an extremity or trunk. We describe a rare case with significant LHIS accompanied by subcutaneous lipomatosis. Echocardiography revealed a mass in the right atrium in this patient. Magnetic resonance imaging revealed that this mass was composed of the adipose tissue and was an extension of a huge thickened IAS. Furthermore, this significant hypertrophy of the IAS was in direct continuation with the excessive mediastinal and epicardial fat.

Studying cardiac masses is one of the most challenging tasks for cardiac imagers. The aim of this review article is to focus on the modern imaging of cardiac masses proceeding through the most frequent ones. Cardiac benign masses such as myxoma, cardiac papillary fibroelastoma, rhabdomyoma, lipoma, and hemangioma are browsed considering the usefulness of most common cardiovascular imaging tools, such as ultrasound techniques, cardiac computed tomography, cardiac magnetic resonance, and in the diagnostic process. In the same way, the most frequent malignant cardiac masses, such as angiosarcoma and metastases, are highlighted. Then, the article browses through nontumoral masses such as cysts, mitral caseous degenerative formations, thrombi, and vegetations, highlighting the differential diagnosis between them. In addition, the article helps in recognizing anatomic normal variants that should not be misdiagnosed as pathological entities.

Authors: Abomandour Hala Gouda , Elnagar Ahmed Mahmoud , Aboleineen Mohamed Wafaie , Shehata Islam Elsayed
Published: August 2022

Objectives:

Type 2 diabetes mellitus (DM) and obesity are an independent risk factor for cardiovascular diseases, so early prediction of LV dysfunction carries better prognosis. So our aim was to assess the subclinical LV dysfunction in type 2 diabetic obese and non-obese patients using two-dimensional speckle tracking echocardiography (2DSTE).

Materials and Methods:

We studied 93 patients, including two groups of 31 each with type 2 diabetes mellitus (T2DM), divided by body mass index (BMI), and 31 non-diabetic non-obese controls. All these subjects underwent two-dimensional Echo (2DE) imaging with analysis of conventional parameters of systolic and diastolic function, as well as speckle tracking echocardiography s (STE) analysis of LV global and regional longitudinal strain.

Results:

We reported significant inter-group differences in parameters of diastolic function, but no significant differences in ejection fraction or fractional shortening. Nevertheless, we found significant differences in strain, which we interpreted as evidence of subclinical systolic dysfunction.

Conclusion:

2DSTE is better than basic echocardiographic measurements in assessment of subclinical LV dysfunction in type 2 diabetic obese and non-obese patients which can be used to predict cardiomyopathic changes in the earlier course of type 2 DM and start earlier treatment with better prognosis.
Critical Analysis of Laboratory Requisition Forms Received in a Cytopathology Laboratory of a Tertiary Care Centre
Authors: Sehgal Shivali , Jetley Sujata , Jairajpuri Zeeba S. , Khan Sabina
Published: August 2022

Background:

A laboratory requisition form (LRF) is the main communication link between the laboratories and the clinicians. In a cytopathology laboratory, incomplete forms with inadequate information significantly impact the quality of the results and waste precious time of the lab.

Aims:

The aim of this study was to audit the LRFs for adequacy of demographic and clinical data and to analyze the reasons for the same.

Settings and Design:

A retrospective study was conducted in the cytopathology laboratory of a tertiary care center.

Materials and Methods:

All the original LRFs received for Pap smears and FNACs of 1-month duration were retrieved. The forms were scrutinized for the presence of specific parameters which were classified as patient information, clinician information and clinical information. In addition to the completeness of the form, clarity of the data was also noted.

Statistical Analysis:

The data were entered on excel worksheets and percentage of Pap smear and FNAC forms lacking information of various parameters was calculated.

Results:

A total of 431 LRFs were received in the month of January 2020. These included 274 Pap smear LRFs and 157 FNAC LRFs. Patient information was mentioned in predominantly all the forms, however, clinician and clinical information, which is indispensible for reporting, was missing in a significant proportion of the Pap smear and fine needle aspiration cytology (FNAC) forms.

Conclusions:

Receiving inadequately filled LRFs has been an age-old problem in all medical laboratories. Audit of inadequacy of LRFs helped in assessing the prevailing practices in the hospital and gave an insight into the quality of information available to the cytologists for reporting. Many clinicians withhold information out of ignorance about its importance or due to lack of time to fill up the details on the LRF. Also, filling out a LRF is a task usually delegated to the junior doctor in the OPD and the significance of filling the LRF correctly and comprehensively is often not emphasized upon adequately by the senior clinicians. This audit helped us taking preventive action by giving feedback to the clinicians and emphasizing to them the importance of clinical data on the LRF and in improvising the LRF using a more objective and user-friendly format.

Authors: Alay G H , Tatlisuluoglu D , Bulut K , Fikri B I , Oztas A , Turan G
Published: August 2022

Background:

Acute phase reactants and inflammation biomarkers such as ferritin, procalcitonin, C-reactive protein (CRP), and complete blood count parameters (White blood cell, platelet count) are usually used to evaluate and monitor the disease severity and treatment response of systemic inflammatory diseases. In addition to these parameters, Immature granulocytes (IG) that increase during systemic infection, hematological malignancy, and drug treatments (such as chemotherapy and glucocorticoids) are important parameters for evaluating systemic inflammation. The sensitivity and specificity of IG are as high as the abovementioned inflammatory biomarkers for monitoring disease severity and treatment response.

Aim:

The aim of the study is to evaluate the relationship between IG count and the need for mechanical ventilation and mortality in patients hospitalized in the intensive care unit (ICU) due to coronavirus disease 2019 (COVID-19).

Patients and Methods:

The medical records of the 401 patients who were followed up in the ICU due to COVID-19-related acute respiratory distress syndrome between October 2020 and February 2021 were retrospectively reviewed. On the day of admission to the ICU complete blood count (CBC), arterial blood gas analysis, coagulation parameters (fibrinogen, D-dimer) are recorded. CRP, procalcitonin, and ferritin levels are also recorded at the day of admission. During the follow-up period, the survival status and mechanical ventilation status of the patients were recorded and the relation between IG count and these parameters was evaluated.

Results:

The mean IG at the admission was 0.2 ± 0.4 109/L. The IG level of the intubated patients at the time of intubation was 0.3 ± 0.5 109/L. There was a significant positive correlation between mortality and IG levels at admission and at the time of intubation (IG admission; P = 0.001, r = 0.347 and IG at intubation; P = 0.001, r = 0.228).

Conclusion:

IG levels in CBC data could be a potential practical biomarker. This issue requires further research and the development of therapies targeting IG cells is needed.
In Vitro Study of the Effect of High Temperature on Erythrocytes in Sickle Cell Trait
Authors: Aljohani Maher M
Published: August 2022

Background:

Although, sickle cell trait (SCT) was considered a benign condition with most patients being asymptomatic, however, there is an impressive increase in the number of sudden deaths in the military recruits and athletes, which has led to SCT as a rapidly emerging medical issue. Genetic factors have been extensively investigated in the etiopathogenesis of SCT but, environmental factors have not been studied in depth.

Aims:

The main aim of this study was to investigate the effect of high temperature on the red blood cells (RBCs) in those with SCT and compare this to a control group lacking SCT.

Patients and Methods:

Heat stress to RBCs was induced by in vitro incubation of freshly drawn blood at high temperatures (45°C for 35 min). Additional information such as hemoglobin (Hb) level, RBC count, mean corpuscular volume (MCV), and hemoglobin S level was obtained from the medical record of the case and control groups. Data were entered in Statistical Package for Social Sciences version 22.0 (IBM Corp, Armonk, NY, United States) and analyzed to examine the research hypothesis.

Results:

A total of 17 blood samples from SCT (HbAS subjects) labeled as cases and 16 samples from controls (HbAA subjects) were included in this study. The results of this study showed no significant change in sickled erythrocytes in SCT in response to in vitro heat stress.

Conclusion:

This study's findings appear to suggest that hyperthermia could be excluded as one of the major factors inducing sickling complications during exhausting exercise. Long-term studies in the future are recommended in this area, particularly to assess the effect of high temperature and sudden death in SCT.
Intravenous Immunoglobulin in Hemolytic Disease of the Newborn
Authors: Vardar G , Okan M A , Karadag N , Topcuoglu S , Ozalkaya E , Karatepe H O , Karatekin G
Published: August 2022

Background:

Alloimmune hemolytic disease of the newborn (AIHDN) results in hemolysis, anemia, hyperbilirubinemia with the potential for brain damage. Intravenous immunoglobulin (IVIG) has been investigated as an alternative low-risk procedure for the treatment of AIHDN in addition to traditional treatment methods such as phototherapy and exchange transfusion (ET).

Aim:

To evaluate the effectiveness of IVIG therapy in decreasing ET needs based on risk factors and clinical outcomes.

Materials and Methods:

Charts of neonates born >30 weeks of gestation who underwent phototherapy and were administered IVIG therapy due to AIHDN between January 2013 and July 2018 were retrospectively reviewed.

Results:

Sixty-three neonates were included in our study. Forty-three of them (68.3) % were full-term infants. ABO incompatibility (n = 33, 52.4%) was the major cause of AIHDN (n = 63). Additional risk factors for jaundice were found to coexist in 95.2% (n = 60) of the infants. Fifteen infants (23.8%) required ET, mostly due to Rh incompatibility (n = 11, 73.3%). Mortality was observed in 3.2% (n = 2) of the patients, 1.6% (n = 1) of whom were related to ET. Serum albumin value was found to be negatively correlated with the requirement for ET (r = 0.713, P < 0.001), whereas serum bilirubin albumin ratio was positively correlated (r = 0.489, _P < 0.001). Nine (14.3%) infants needed a simple transfusion during the hospitalization period, whereas five (7.9%) infants had readmission for simple transfusion after discharge. Apnea was the only complication seen in one (1.6%) patient.

Conclusion:

IVIG treatment should be considered due to its relative benefits when compared to exchange transfusion. In addition to its safety, it is a less complicated treatment modality with low side effect rates. It may be justified for elective use in neonates suffering from AIHDN, who will require ET with a risk of mortality by decreasing the peak of total serum bilirubin levels.

The study analyzed 33 patients with a median age of 59.79 ± 9.0 years. There was a significant difference preoperatively versus postoperatively in terms of all PSQI global scores and subdivisions (P < 0.001). A statistically significant improvement was determined by the simple shoulder test, the Constant and Murley shoulder scores, and VAS (P < 0.001).

Conclusion:

Sleep disturbance is common in patients with symptomatic rotator cuff tear, and sleep disturbance can resolve after arthroscopic rotator cuff repair.
Ureteropelvic Junction Obstructions
Authors: Ozaydin S , Celebi S
Published: August 2022

Background:

Ureteropelvic junction obstructions (UPJOs) occur more frequently on the left than on the right side. Among patients diagnosed during the neonatal period, those with left-side UPJO have a more severe course than those with right-side UPJO.

Aim:

This study examined clinical advances in the surgical management of right and left symptomatic UPJOs preoperatively and postoperatively, based on a retrospective analysis of cases.

Patients and Methods:

In this retrospective clinical trial, 650 patients were evaluated at the time of diagnosis and at surgery.

Results:

Left-side UPJO was diagnosed in 66.1% of patients (P = 0.017). The median age of the patients at surgery for left- and right-side UPJO was 1.5 and 4.2 years, respectively (P = 0.001). At the preoperative evaluation, the ratio of parenchymal thickness (RPT) on the UPJO side versus the contralateral side was 0.55 ± 0.3 and 0.7 ± 0.3 for patients with left-side and right-side UPJO, respectively (P = 0.029). RPT during the first postoperative year was 0.83 ± 0.2 for patients treated on the left side and 0.9 ± 0.3 for those treated on the right side (P = 0.25). The respective values at 3 years postoperatively were 0.8 ± 0.3 and 0.9 ± 0.2 (P = 0.09). The preoperative kidney function value in the left-side group was 42.5 ± 13.4, which declined to 39.52 ± 15.8 at the 3-year follow-up examination. In the right-side group, preoperative kidney function was 38.8 ± 16.1, which increased to 40.2 ± 13.2 at 3 years postoperatively. Both the decline and improvement were significant (both P = 0.006).

Conclusions:

Those with left-side UPJO had a more severe course than those with right-side UPJO.

Le corossolier (Annona muricata L.) fait partir des espèces très sollicitées du point de vue socioéconomiques et thérapeutiques. Les difficultés de  régénération naturelles que connaît cette espèce réduisent sa distribution géographique impactant ainsi sa production au niveau du Cameroun. Face à cette contrainte, une étude axée sur le test de germination du corossolier a été effectuée au sein de la Station polyvalente Agricole de  Bertoua. L’approche méthodologique inclue l’application de 4 traitements à 4 lots de semences constitués suivant la durée de conservation. Les  résultats obtenus ont montré un taux de germination au-dessus de 80% pour la quasi-totalité des traitements appliqués aux différents lots, excepté  le témoin qui a eu un taux de germination de 67%. Le délai de germination débute le 25ème jour et va jusqu’au 31ème jour pour une durée de  germination variant de 2 à 6 jours. Les taux de germination ont régressés avec la durée de conservation et les graines conservées pendant 90 jours  ont eu le plus faible taux de germination.  Les traitements scarification et trempage des graines ont améliorées significativement le taux de germination des graines de corossolier et la conservation des semences au-delà de 90 jours affecte leur qualité germinative. Cette étude est une contribution sur les connaissances en rapport avec la durée de conservation sur la germination des graines de corossolier.
Actio de in rem verso. An Unwanted Continuity. The Doctrine of versio in rem in the Austrian Civil Code and Interwar Legal Discussion in Czechoslovakia
Authors: Dostalík Petr
Published: August 2022

This paper concerns of the doctrine of versio in rem (or actio de in rem verso) in the legal discussion in interwar Czechoslovakia. The paper presents a brief overview of the origin and field of application of actio de in rem verso in classical Roman law and the transformation of the doctrine of versio in rem i n the frame of Corpus Iuris Civilis. The scope of the changes made by the compilers is still uncertain and was a subject of extensive discussion among the legal scholars of the 19th century. The paper describes the nature of versio in rem in the Austrian Civil Code (provision of §1041) and presents legal statements of the prominent exponents of the various legal schools of interwar Czechoslovakia, the legal traditionalists and the supporters of the School of Pure Law Theory. The doctrine of versio in rem is still in the centre of attention of the modern legal scholars in the Czech Republic. The doctrine of versio in rem was adopted in the new Czech Civil Code, but without reflecting the results of the interwar discussion.
The Changes in the Right of Novelty in Hungarian Civil Procedure in the Interwar Period
Authors: Szivós Kristóf
Published: August 2022

As a result of the codification of Hungarian civil procedure, the first modern code of civil procedure was enacted in 1911. It was characterised by the principles of orality, immediacy, and publicity. An important question of the legislation was to decide to which extent should the parties be allowed to propose new allegations and proofs in the second instance proceedings. Furthermore, the legislative reforms of the interwar period amended the regulation of the appeal as well. The study examines these questions with the help of the primary sources of the era.

HF RADIATION PULSE SOURCE LOCATING IN DIN-2K ACCELERATOR
Authors: Druj O.S. , Yegorenkov V.V. , Marchenko S.V. , Yuferov V.B.
Published: August 2022

Experiments aimed at locating the source generating an HF pulse during the opening of the plasma switch and leading to explosive electron emission at the cathode were performed on DIN-2K pulse accelerator. It is demonstrated that certain lamps glow during the explosive electron emission pulse. This may point to the possible HF pulse generation during the opening of a plasma switch or radial interruption of current. In order to locate the radiation source the FR-2 dielectric insert was introduced into the vacuum diode and Ne lamps were placed over the anode mesh. The thickness of this insert was chosen to be larger than the electron penetration depth. The lack of Ne indicator lamps glow when the anode was shielded by an FR-2 insert was observed as opposed to the case of operation with the vacuum diode as a load. The virtual cathode caused by the explosive emission from the cathode is shown to be the source of HF radiation.
The Rise of the White Serbia in the Light of the Merovingians’ Thuringia Policy
Authors: Vatseba R.
Published: August 2022

The study offers an analytical overview of the international relations in the territory of the Middle Elbe basin from the 530s until the early 8th century, specifically concerned with the policy of the Merovingian kings towards the former Thuringian kingdom lands and the issue of the rise of White Serbia. The author considers Frankish policy as an influencing factor in slavisation of the discussed region while examining the impact of a wider spectrum of possible factors, in particular, the changes in ecology and the Avar presence in the Middle Danube region. The chronology of the Serbian settlers’ arrival into the Middle Elbe valley as well as their political & legal status in that land are specified. The author discusses the issue of the White Serbs’ initial foreign policy orientation and investigates the causes, direction, time & consequences of its change. The main research content is complemented by the excurses on the climatic crisis of the Late Antique Little Ice Age and chosen aspects of the Avars’ & the White Serbs’ early ethnic history. The author develops W. Fritze’s hypothesis of the Merovingians’ active involvement and support of the Serbian immigration into the Middle Elbe and Saale region together with an idea of anti-Avar direction of this measure. Whereas, the results of the study have rejected the assumptions, that the Elbe Germans abandonment of the area to the east of the Elbe and Saale at the end of the third quarter of the 6th century was caused by the Frankish-Avar agreement or Slavic pressure. The author concludes that the first group of the Serbian settlers arrived to the Middle Elbe and Saale from the North-Western Bohemia during the Austrasian king Theudebert ІІ’s reign, probably, at the invitation of the famous Brunhilda, receiving the lands in Thuringia’s border zone as the Frankish foederati. The interconnection between the initial successes of the Merovingians’ Serbian policy in the east of Thuringia during the first decades of the 7th century and the settlement of the Croats & Serbs in the Balkans by the emperor Heraclius is revealed. It has been demonstrated that further expansion of the White Serbia’s territory from the 630s was of spontaneous nature and took place under the circumstances of the collapsed Merovingian control over Thuringia.

Authors: Márquez Juan José Palacios , Pérez Jessica Quintero , Monreal Marleni Reyes , Escalera Miguel Pérez , Lazalde Arturo Reyes , Bonilla María Eugenia Pérez
Published: August 2022

El colesterol es una molécula lipídica que participa en la permeabilidad de la membrana celular, en procesos de señalización transmembranal y en la producción de hormonas esteroideas. El hígado y el intestino regulan la concentración sanguínea de colesterol (colesterolemia) a través de la síntesis, consumo de alimentos, almacenamiento y excreción. Niveles altos de colesterol sanguíneo (hipercolesterolemia) causan complicaciones fisiopatológicas que implican costos biológicos y económicos. Se realizó un programa de cómputo formado por tres módulos: (1) leccionario, (2) modelos matemáticos y (3) módulo de simuladores: simulador hepato-intestinal y simulador de regulación génica de la síntesis de colesterol en el hepatocito. El programa fue compilado en lenguaje Visual Basic® 6.0 para ambiente Windows®. Los simuladores pueden reproducir el control de la concentración de colesterol en condiciones normales y patológicas.

Published: August 2022

O Business Intelligence (BI) é um conjunto de ferramentas utilizadas em organizações públicas e privadas, que possibilita resultados com dados precisos, utilizando-se de um banco de dados multidimensional, orientado por assunto, não volátil, histórico, decisório e variável em relação ao tempo. Ao aplicar o uso do Data Mart para uma Instituição Federal de Ensino no setor de gestão de pessoas, essa pesquisa trabalhou especificamente com dados de servidores aposentados e ativos da Universidade Federal de Viçosa (UFV) a fim de desenvolver indicadores para a tomada de decisão. Questões como a falta de sinergia entre as bases de dados existentes, qualidade dos dados fornecidos e impossibilidade de emissão de relatórios gerenciais em tempo hábil, foram tratadas nesse estudo. As ferramentas BI possibilitaram o preenchimento dessas lacunas, empregando as etapas: processo ETL (Extract, Transform, Load) com extração, tratamento e carga de dados no Data Warehouse; visualização de dados analíticos em relatórios, gráficos, tabelas e mapas. Concluiu-se que a aplicação e implantação de Business Intelligence por meio do Data Mart, com ferramentas open source, pode gerar dados precisos e fornecer indicadores de desempenho, auxiliando nos processos decisórios das Instituições.
