Can we apply biomarkers in the management of non-steroidal anti-inflammatory drug exacerbated respiratory disease?
Authors: Rhyou Hyo-In , Nam Young-Hee , Park Hae-Sim
Published: August 2023

Non-steroidal anti-inflammatory drug (NSAID)-exacerbated respiratory disease (NERD) is characterized by adult-onset asthma, chronic rhinosinusitis with nasal polyps (CRSwNPs), and aspirin/NSAID hypersensitivity, presenting recurrent asthma exacerbation and poor clinical outcomes. Patients with NERD have heterogeneous clinical phenotypes/endotypes, and the management of NERD remains challenging. Dysregulation of arachidonic acid (AA) metabolism and persistent eosinophilic airway inflammation are the major pathogenic mechanisms in the upper and lower airways of NERD. To date, increased levels of urinary leukotriene E4 (uLTE4) [a terminal metabolite of the lipoxygenase (LOX) pathway] have been the most relevant biomarker for NERD. It is demonstrated that mast cells, platelets, and epithelial cells can amplify upper and lower airway inflammation in NERD, and several potential biomarkers based on these complicated and heterogeneous mechanisms have been suggested. This review summarizes potential biomarkers for application in the management of NERD.

Moosmonitoring: Trends in der Anreicherung von Metallen und Stickstoff und Einflüsse der Vegetationsstruktur/Moss monitoring: Trends in metal and nitrogen accumulation and influences of vegetation structure
Authors: Völksen Barbara , Dreyer Annekatrin , Nickel Stefan , Schröder Winfried
Published: August 2023

Ziel der hier vorgestellten Untersuchungen war es, die Trends der Metall- und Stickstoffakkumulation in Moosen zwischen 1990 bzw. 2005 und 2020 in Deutschland sowie die Auswirkung der Baumkronentraufe auf die Elementanreicherung zu ermitteln. Für die Trendanalyse wurde die Mindeststichprobenanzahl berechnet, die für eine zuverlässige Schätzung arithmetischer Mittelwerte und darauf beruhender statistischer Kennwerte erforderlich ist. Die Mindestprobenzahl wurde nur bei den Stickstoffmessungen erreicht. Daher wurden die Trends der Bioakkumulation von Metallen und Stickstoff anhand der Medianwerte berechnet. Für die Analysen der Baumkronentraufeffekte auf die Elementgehalte in Moosen wurden 14 Vegetationsstrukturmaße verwendet. Der Vergleich der bei der ersten Monitoring-Kampagne ermittelten Daten mit denen der Erhebung von 2020 zeigte einen deutlichen Rückgang der Bioakkumulation von Metallen. Im Gegensatz zu den Daten für die deutsche Berichterstattung atmosphärischer Metallemissionen stiegen zwischen 2000 und 2005 die Gehalte einiger sowie von 2015 bis 2020 die Gehalte aller Metalle in Moosen an. Die Konzentrationen von Metallen und Stickstoff waren unter Baumkronen signifikant höher als im Freiland. Die Stickstoffmediane sind zwischen 2005 und 2015 um –2 % gesunken und zwischen 2015 und 2020 um 8 % gestiegen. Diese Unterschiede sind nicht signifikant und stimmen nicht mit den Daten für die deutsche Berichterstattung atmosphärischer Stickstoffemissionen überein.

Authors: Probst Wolfgang
Published: August 2023

Der Verfasser dieses Beitrags hat sich als Obmann der Arbeitsgruppe ISO TC43 SC1 WG61 im Rahmen einer Revision der ISO 9613-2 mit den international vorliegenden Studien zum Vergleich Rechnung – Messung für WEAs befasst, da mit einem neuen Annex zu dieser Anlagenart der weltweiten Anwendung der Norm als Prognoseverfahren für die zu erwartende Schallimmission bei Standortplanungen Rechnung getragen werden sollte. Im Zuge dieser Revision – Stand zum Zeitpunkt dieses Beitrags siehe [1] – wurde auch ein Verfahren zur Berücksichtigung der Windklimatologie bei der Bildung der meteorologischen Korrektur Cmet bzw. der in großen Abständen aus der Windverteilung abgeleiteten Richtwirkung C0 aufgenommen. Der Kern des Konzepts ist auch in dieser Zeitschrift mit mehreren Beiträgen [8 bis 12] beschrieben und weiterentwickelt worden. Im Nachfolgenden wird das Konzept zur Verwendung des Langzeit-Mittelungspegels als bestimmender Kenngröße zur immissionsschutztechnischen Beurteilung von Windenergieanlagen (WEAs) als Alternative zur derzeitigen Beurteilungspraxis vorgestellt und beispielhaft erläutert. Es stellt aus Sicht des Verfassers alternativ zur gegenwärtigen Maximalwertbetrachtung eine geeignetere Methodik dar, um eine angemessene Balance zwischen den Anforderungen des Lärmschutzes einerseits und den ebenfalls ernst zunehmenden Anforderungen nach einer verstärkten Nutzung der Windenergie andererseits gerecht zu werden.

Authors: Ahmad Sajjad , Rashid Haji Muhammad , Hassan Hiza , Mujahid Muhammad , Gul Maryam
Published: August 2023

Background: Thyroid hormone variations have been observed according to age and sex. Seasonal effects also induce variations in thyroid function even in people with normal thyroid levels. The majority of clinical laboratories follow a single reference range without the consideration of age, gender, and especially seasonal variations in thyroid function tests.

Objectives: To evaluate age, gender, and seasonal variations in thyroid function tests in adults with normal thyroid functions.

Methodology: This cross sectional study was carried out at Pathology Department, Quaid-e-Azam Medical College, Bahawalpur. One year data from Jan 2018 to Jan 2019 of thyroid function tests (TSH, T3 and T4) and demographic details were obtained for all those patients whose Thyroid Stimulating Hormone (TSH) was in normal reference range (0.5-4.5mU/L). We found the data of 418 subjects from 16 to 75 years of age, among them 196 were females and 222 were males.

Results: Serum TSH levels were higher in females (2.11mU/L ±1.54) than serum TSH levels of males (1.59mU/L ±1.2) with a p-value of 0.0002. FT4 levels (normal range: 0.89-1.76ng/dL) were significantly lower (p-value 0.0018) in females (1.33ng/dL ±0.50) as compared to males (1.48ng/dL ±0.48). In <20 years of the age group of both genders, serum TSH was at lowest levels, while highest in 20-40 years of the age group of males and >60 years of females. The mean TSH of all subjects was high (2.98mU/L) in winters and it was low (2.4mU/L) in autumn. FT4 was at the lowest level (1.16ng/dL) in winters and it was highest (1.46ng/dL) in summers. FT3 levels in the winter season were higher than in other seasons.

Conclusion: Age, gender, and season affects the thyroid hormones levels, and these factors should be considered while interpreting the lab results of thyroid function tests.

Authors: Panhwar Bushra Urooj , Keerio Abdullah , Panhwar Aasia Akbar , Panhwar Rabia Akbar , Panhwar Faiz Hussain , Channa Abdul Razzaque
Published: August 2023

Background: A key desire of a farmer is to produce a higher yield with low inputs. Through proper nutrient management, potential yield can be picked but mostly cotton is not grown with balanced nutrition. In this scenario, seed priming and foliar fertilizers have the advantage of quick plant responses. Therefore, a cost-effective, farmers-friendly, and full of nutrients supplement should be considered. Moringa is known as a miracle plant and its role as a seed priming agent and foliar spray has been observed in many other crops.

Objective: In this regard present study was conducted to evaluate the effect of the leaf extract of a miracle plant (Moringa oleifera L.) on the growth and development of cotton.

Methodology: Two cotton varieties CRIS-585 and CRIS-342 were seeded with an experimental design of split-plot repeated thrice. The details of the experiment were i) control ii) foliar spray of tap water iii) seed priming with leaf extract of miracle plant (MLE), iv) seed priming and foliar spray with MLE v) foliar spray with MLE. The extract was 3% solution. Cotton seeds were soaked to complete seed priming for 3 hours. After emergence 30, 60, and 90 days were selected to apply the foliar spray.

Results: It indicated from the application of leaf extract that seed priming, as well as a foliar spray on cotton crops, had significant (p=0.05) effects on its yield and related parameters. The highest boll weight (3.8 g) and seed cotton yield (3844 kg ha-1) were recorded when a combined application of seed priming and foliar spray was done followed by the sole application of the foliar spray. While the minimum values of boll weight and seed cotton yield were found from the control where no seed priming or foliar spray was done.

Conclusion: It is concluded that the application of leaf extract of miracle plants as seed priming and foliar spray in cotton crops significantly affected seed cotton yield and its traits.

Authors: Malik Rubab , Khatoon Nasira
Published: August 2023

Background: Poultry production in Pakistan is growing remarkably and contributing significantly to the economy. However, disease outbreaks are the most serious threat to poultry productivity. Among other poultry diseases which cause huge damage to poultry, parasitic diseases are also included, but no significant work has been done on this area of concern in Pakistan.

Objective: This study is carried out to evaluate the prevalence rate of one of the major helminth parasite groups, Cestodes, and their effects on the health of chickens in the districts of Korangi, Karachi, Sindh.

Method: Between February 2018 and January 2019, 76 chickens were examined for Cestodes infection. Cestodes were extracted from the gut and fixed in F.A.A. fixative for 24 hours with a little cover slip pressure. The cestodes were then thoroughly cleaned with 70% ethanol, stained with Mayer's carmalum, dehydrated in progressively stronger alcohol, clarified with clove oil, rinsed with xylene, and permanently mounted in Canada balsam.

Results: The overall prevalence was 52.6%. Parasite burden is high in males (63.8%) compared to females (45.6%). Six species of Cestodes parasites were identified from the intestine of the infected chickens. Raillietina tetragona, R. cesticillus, R. echinobothridia, R. ransomi, Choanotaenia infundibulum, and Raillietina sp. are the Cestode species that have been found. Their prevalence was 42.1%, 34.2%, 26.3%, 22.2%, 15.7%, and 7.8%, respectively. The prevalence rate also varies from season to season. Spring had the highest rate of infection at 60%, summer was next at 58%, and autumn and winter both had a rate of 40%.

Conclusion: The study concludes that heavy infestation has a negative impact on the physical health of chickens and points to the need to control Cestodes parasite infection in order to reduce mortality and increase poultry yield.

Authors: Wang Shijin , Zhou Huiying , Tian Keqin
Published: August 2023

Industrial structure upgrading plays an important role in improving economic development efficiency. Taking Jiangsu as the study subject, the paper selects panel data from 2005 to 2018 and performs dynamic panel models and threshold models to analyze the influence mechanism of foreign direct investment (FDI) and green technology innovation on industrial structure upgrading (including rationalization and advancement). The results show that FDI acts negatively on industrial structure upgrading, exhibiting U-shaped relationship with advancement, in contrast, green technology innovation shows a positive contribution to upgrading. In addition, rationalization is limited by fixed assets growing but increases with rising education levels. An increase in fixed assets and education both have a positive effect on advancement. Further, FDI plays a facilitating role in advancement considering the positive moderating effect of green technology innovation. Therefore, the study provides a theoretical reference for the development path of foreign investment and industrial structure upgrade breakthrough in Jiangsu.

The relationships of these two taxa and their close relatives are clarified. Data on the sexual dimorphism of the two new taxa and on the intrasubspecific variability of S. coriniensis nonveillerissp. nov. are presented. We also redescribed S. novaki, the type species of both the genus Spelaeobates and the subgenus Spelaeobates and the closest relative of the newly described species. A key for identification of the taxa of the genus Spelaeobates is included. The new taxa are endemic to the Dinaric Alps of Croatia. Spelaeobates (Pretneriella) kraussi Müller, 1903 and S. (P.) pharensis langhofferi Müller, 1931 were found for the first time outside their type locality.

The present paper reports the first occurrence of Seira ferrarii Parona, 1888 from Hungary. On this occasion, molecular analyses were performed on both S. ferrarii and another historical species of the genus, S. pallidipes Reuter, 1895, originally described from Hungary. Using low-coverage whole-genome sequencing, the complete mitogenomes were assembled and annotated using MitoZ. To test the phylogenetic placement of both species, we performed maximum likelihood and Bayesian analyses using a matrix containing 14 Seirinae species and two outgroups. Both resultant trees showed that the European populations of the sampled Seira spp. likely derive from ancestral branches of Seirinae, compared to the Asian and American populations. Our results put in question the monophyly of the genus Seira, as already observed in previous studies.

Medical institutions in loose medical consortia tend to have poor cooperation due to fragmented interests. We aim to explore any issues associated with patient upward transfer in a loose medical consortium system consisting of two tertiary hospitals with both cooperative and competitive relationships. A two-sided evolutionary game model was constructed to assess the stability of equilibrium strategy combinations in the process of interaction between game players under different cost-sharing scenarios and different degrees of penalties when running patient upward transfer between super triple-A hospitals (STH) and general triple-A hospitals (GTH). We found that a hospital's stabilization strategy was related to its revenue status. When a hospital has high/low revenues, it will treat patients negatively/positively, regardless of the strategy chosen by the other hospital. When the hospital has a medium revenue, the strategy choice will be related to the delay cost, delay cost sharing coefficient, government penalty and the strategic choice of the other hospital. Delay cost-sharing coefficient is an important internal factor affecting the cooperation in a medical consortium for patient upward transfer. External interventions, such as government penalty mechanisms, can improve the cooperation between hospitals when hospitals have moderate revenue.

Characterisation of Residual Stresses of Rheocast Al Alloy
Authors: Fracchia Elisa , Gattelli Ivano , Grande Marco Actis
Published: August 2023

Rheocasting is a semisolid casting process allowing to obtain near-net shape parts. Through the Rheocasting process, it is possible to achieve aluminium castings having a low grade of porosity if compared to traditional die-casting methods, encouraging the production of automotive frame parts. However, casting processes, as commonly known, may cause tensile residual stresses inside the parts. On the other hand, compressive stresses inside castings can significantly increase the life of components: residual compressive stresses increase the material's resistance by counteracting crack initiation and propagation. The cracks propagate when the material is under tensile stress, while the Rheocasting technique seems to promote compressive stresses inside the castings. This work aims to analyse an aluminium rheocasted frame component for race cars in both the as-cast and heat-treated conditions. First, the mechanical properties of the components were evaluated in terms of tensile tests and microhardness. Then, residual stresses were measured at specific points of the casting. Finally, the evolution of the residual stresses inside the component before and after heat treatment led to assessing the effect of the Rheocasting process condition and the heat treatment, proving the marked advantage of using such a technology.
Mechanical and Microstructural Investigations on a Symmetric Mould Processed with Semi-Solid Aluminum RheoMetalTM: Analysis of the As-Cast Proprieties

Published: August 2023

High-pressure die-casting (HPDC) can be a productive process for high-quality cast aluminium alloy components. However, it is also a process prone to generate defects, such as gas porosities and incomplete fillings, resulting in rejections. One way to reduce the reject rate is to employ Semi-Solid Metal processing with HPDC. The most important advantages of Semi-Solid alloys are reduced shrinkage defects, fewer gas porosities, and fewer chances of filling-related problems. To take full advantage of a semi-solid metal slurry, the casting process must be controlled meticulously to reach homogeneous casting quality and high process repeatability. A study has been conducted on cast parts composed of two-dimensional symmetrical cavities. From the mechanical tests, unexpected differences emerged in both tensile strength and fracture elongation, which were confirmed by differences in the microstructure. The paper investigates the reasons for the asymmetry in the proprieties to avoid similar problems in future studies and maximize the effectiveness and repeatability of the high-pressure die-casting process.
A Comparative Study on Microstructure, Mechanical Property, and Electrical Conductivity of Al-7Si-0.6Mg Alloy Produced by High Pressure Die Casting and Semisolid Die Casting

Published: August 2023

Two casting technologies were introduced to fabricate the Al-7Si-0.6Mg alloy, including high pressure die casting (HPDC) and semi-solid die casting (SSM). The microstructure and mechanical property were studied by optical microscopy (OM), scanning electron microscopy (SEM), X-Ray diffraction (XRD), microhardness and tensile test. The electrical conductivity was also introduced to evaluate the thermal conductivity of the alloys. Results show that the as-cast microstructure of the HPDC alloy and SSM alloy both consists of primary α-Al, eutectic Si and Mg2Si phase. The primary α-Al phase in HPDC alloy possesses fine equiaxed dendrite structure with an average grain size of 29.4 μm. While the SSM alloy forms abundant coarse and globular structure α-Al phase, and the average grain size reaches 98.9 μm. This is because of the lower cooling rate during slurry preparation promotes the formation of a relative coarse microstructure in the SSM alloy. Furthermore, the increased content of eutectic Mg2Si phase was also detected in the SSM alloy. Therefore, the average yield strength and ultimate tensile strength decreases from 148 MPa and 275 MPa of the HPDC alloy to 140 MPa and 254 MPa of the SSM alloy, respectively. However, the elongation and electrical conductivity of the SSM alloy both increases from 5.8±1.3% and 20.0±0.1 MS/m of the HPDC alloy to 7.5±1.2% and 20.6±0.1 MS/m, respectively.

A strip caster was used to cast two types of aluminium alloys: an almost eutectic Al-Si alloy (Al 10 Si) with contaminants of 0.6 Fe, 0.2 Pb, and 1.4 Sn, which exhibits a polyphase microstructure upon solidification, and recycled aluminium beverage cans made from Al 0.8 Mn alloy containing 0.4 Si, 0.5 Fe, and 0.1 Mg, which has a monophase microstructure upon solidification. The molten materials were poured at 650 oC (Al 10 Si) and 670 oC (Al 0.8 Mn, 0.4 Si, 0.5 Fe, 0.1 Mg) on a cooling slope specially designed to obtain a semisolid material. This semisolid material was then dragged between rolls at a rate of 0.2 m/s to obtain high-quality metal strips. There was less eutectic modification with larger Al-α grains in the middle region of the sheet between the fine eutectic layers, indicating a lower cooling rate. However, during the recycling of aluminium beverage cans, large grains were formed with a columnar structure at the interface of the rolls, and semisolid melts with cracks were formed between the columnar grain boundaries owing to the compression of the rolls. The middle of these grains contained smaller equiaxial grains that were subjected to dragging. The as-cast specimens were submitted to homogenisation heat treatment at 560 oC for a period of 10 h and cooled to room temperature before being cold rolled (Temper H18) and recrystallised (Temper O) to examine the effect of these treatments on the tensile mechanical properties. During cold rolling (Temper H-18), grain alignment occurred with a yield stress, maximum stress, and elongation of 209.5 MPa, 210.1 MPa, and 2.8%, respectively. The strength decreased (yield stress of 58 MPa and maximum stress of 120.2 MPa) under recrystallisation conditions (Temper O), but the ductility increased (8.9%). This is in contrast to the Al-Si (Al 10Si) strip, which exhibited a yield stress, maximum stress, and elongation of 103.3 MPa, 128.7 MPa, and 1.9%, respectively. The A1 10Si strips also fractured during cold rolling, indicating high material fragility.

In this paper, both thixocasting and rheocasting of Al-7Si-0.6Mg alloy (EN AC 42200) for the same part was performed. It was found that rheocasting of Al-7Si-0.6Mg alloy show a smaller primary Al grain size and significant improvement of cast defects compared with thixocasting of Al-7Si-0.6Mg alloy. This paper demonstrates that rheocasting of Al-7Si-0.6Mg alloy is more beneficial in terms of microstructure and cast defects compared with thixocasting of Al-7Si-0.6Mg alloy.

Early Childhood Education (ECE) is the foundation of education which helps to develop the child’s cognitive, emotional, and physical aspects. Unquestionably ECE educators play a vital role. Hence, teacher education in early childhood context is very important. However currently in Sri Lanka only very few state universities conduct Bachelor of Education in ECE and Primary Education and while other Non-State Higher Education institutes (NSHEIs) offer Early Childhood Education degrees affiliated to foreign universities. Further, presently no NSHEI offer the Ministry of Education or University Grants Commission approved degree in Early Childhood Education. Hence in this context objective of the study is to investigate the need for the Bachelor of Education ECE Degree programme at NSHEI in Sri Lanka. Study conducted in one of the prominent NSHEIs (ABC institute) in Sri Lanka. Therefore, Case study method adopted, and quantitative measures have been complemented with the qualitative measures. Sample size is seventy-five student teachers at ABC institute. This is a survey research and data collection methods are questionnaire for student teachers and key informant interviews conducted with some key stakeholders in the state universities and three preschool owners in Colombo district. Results of the study revealed that benefits of the ECE Degree to students and for the country and emphasized it is very crucial to commence the ECE programme as it provides more opportunities to students since few opportunities and capacity restraint in state universities. Furthermore, study highlighted that ninety six percent student like to start ECE Degree and if the institute commence the programme ninety percent student would like to join the programme. Therefore, study can be concludedthat ABC as a NSHEI there is a good potential and opportunity to proceed with the ECE Degree and contribute to the foundation of the education in the country which add value to the system.
