Published: March 2023

OBJECTIVE

To investigate the effects of interleukin-1β (IL-1β) and methylprednisolone acetate (MPA) on equine intrabursal deep digital flexor tendon (DDFT) and navicular bone fibrocartilage (NBF) cells in vitro.

SAMPLE

Third passage DDFT and NBF cells from 5 healthy donor horses ages 11–17 years euthanized for reasons unrelated to musculoskeletal conditions.

PROCEDURES

Aggregate cultures were incubated with culture medium alone (control), 10 ng/mL IL-1β, 10 ng/mL IL-1β + 0.05 mg/mL MPA, or 10 ng/mL IL-1β + 0.5 mg/mL MPA for 24 hours. Extracellular matrix (ECM) gene expressions were assessed via real-time polymerase chain reaction (rtPCR). Culture media matrix metalloproteinase (MMP) -3 and -13 concentrations were quantified via ELISA. Total glycosaminoglycan (GAG) content in the cell pellets and culture media was also assessed.

RESULTS

IL-1β and IL-1β combined with MPA significantly downregulated ECM gene expression to a greater extent in NBF cells compared with DDFT cells. IL-1β and IL-1β combined with MPA significantly upregulated MMP-3 culture media concentrations in DDFT cells only, and MMP-13 culture media concentrations to a greater extent in NBF cells compared with DDFT cells.

CLINICAL RELEVANCE

NBF cells were more susceptible to IL-1β and MPA-mediated ECM gene expression downregulation in vitro. These results serve as a first step for future work to determine intrabursal corticosteroid regimens that limits or resolve the inflammation as well as take into consideration NBF cell biosynthesis in horses with navicular disease, for which currently no information exists.

Published: March 2023

OBJECTIVES

This study aims to assess intrathecal mepivacaine for euthanasia in anesthetized horses and compare it to a traditional euthanasia method using a single intravenous injection of pentobarbital in sedated horses.

ANIMALS

Client-owned horses and horses requiring euthanasia due to involvement in concurrent research projects were used. Horses were randomly assigned to 1 of 2 groups: intrathecal mepivacaine after anesthesia or intravenous pentobarbital after sedation. All horses had normal vital parameters and no signs of infectious disease at the time of euthanasia.

PROCEDURES

The intrathecal mepivacaine group was anesthetized before the intrathecal injection of mepivacaine. The pentobarbital group was sedated, concurrently anesthetized and euthanized using intravenous pentobarbital, then received an intrathecal saline (0.9% NaCl) solution injection to a blind observer. Both groups were sedated with detomidine and the time from sedation to the cessation of vital parameters (respirations, pulse, corneal reflex, and ECG) was recorded. Euthanasias were recorded for review by a blinded anesthesiologist, using an independent scale to assess the quality of sedation, anesthesia induction, and lateral recumbency.

RESULTS

Time from detomidine administration to cessation of each vital parameter was significantly longer in the intrathecal mepivacaine group. There was no statistically significant difference in qualitative scores between groups for sedation or induction, but lateral recumbency was subjectively superior in the anesthetized intrathecal mepivacaine group.

CLINICAL RELEVANCE

Intrathecal mepivacaine provided a safe, effective, alternative method of euthanasia to intravenous pentobarbital and addresses concerns about barbiturate availability. This study also informs practitioners of what to expect (ie, longer cessation of vital parameters) when using the intrathecal mepivacaine method.

Published: March 2023

The aim of the study was to determine the effect of the inclusion of 2%, 4% and 6% extruded flaxseed in the diet of fattening pigs on their growth performance parameters, carcass parameters, and selected blood parameters. The experiment was conducted on 160 weaners (from about 30 kg to about 110 kg BW) assigned to four experimental groups of 40 animals each (5 replicates with 8 individuals each). The animals in control group received a diet in which the source of fat was soybean oil. The other groups received extruded flaxseed (FE) in place of soybean meal in the amount of 2% (group 2FE); 4% (group 4FE) and 6% (group 6FE). Soybean oil was added to the diets in the experimental treatments to obtain equal amounts of fat. The inclusion of 2% and 4% extruded flaxseed in the diet of fatteners in place of soybean meal significantly improved the digestibility of basic nutrients, i.e. ether extract (by about 5%) and dietary fibre (by more than 20%) and led to better growth performance (higher BW by about 11%; higher ADG by about 20% and lower FCR by about 12%) vs group C. In the groups with 2% and 4% extruded flaxseed there was also an increase in the lean meat content of the carcasses (by about 6%) and the thickness of the backfat (by about 6.5%) vs group C. The inclusion of extruded flaxseed did not affect the animals’ condition, as indicated by the haematological and biochemical parameters of the blood, which were within reference ranges. The results for production, nutrient digestibility and carcass analysis between groups 2FE and 4FE were similar, and at this stage of research indicate that the use of 2% extruded flaxseed is economically more justified.

The combined effects of Spirulina platensis (SP) and Pediococcus acidilactici (PA) on growth performance, digestive enzyme activity, antioxidative status, and immune genes in zebrafish were investigated in the present study. Four experimental diets were designed: control and three test diets mixed with SP at 2.5%, PA at 107 CFU/g, or a combination of 2.5% SP and 107 CFU/g PA. After 56 days, fish treated with PA and SP mixture had higher final weight, weight gain, SGR, and lower FCR than fish fed the control and SP diets (P<0.05). The results also illustrated that fish fed PA, SP, and their mixture had higher (P<0.05) protease and amylase activities than the control. The lipase activity was significantly higher in fish treated with PA or the mixture of PA and SP than in the control (P<0.05). The alternative complement pathway (ACH50) and lysozyme activity in the mucus samples of fish treated with PA or both PA and SP were significantly higher (P<0.05) than in fish treated with the control and SP diets. The total immunoglobulin level in the skin mucus was significantly higher (P<0.05) in fish fed PA than in control. In the body homogenates samples, the lysozyme activity and immunoglobulin levels were markedly higher (P<0.05) in fish treated with the mixture of PA and SP than in the control. The dietary PA and SP diet mixture improved the glutathione peroxidase, superoxide dismutase, and total antioxidative capacity. The expression of IL-1β and IL-8 genes in fish treated with PA or the mixture of PA and SP was significantly higher (P<0.05) than in fish treated with the control or SP diets. Fish treated with PA, SP, or both PA and SP had marked (P<0.05) upregulation of the lysozyme gene expression. In conclusion, the mixture of S. platensis and P. acidilactici is more effective than using each individually for improving the growth performance, digestive enzyme activity, and the immune and antioxidative capacity of zebrafish.

Published: March 2023

The article aims to provide an overview of the interrelationships between public knowledge, attitudes, and practical behaviours in the context of a global pandemic and the risk management measures used by the government. By reviewing some of the key trends in crisis management in Lithuania, it seeks to explore the response of society. The aim of the paper is to analyse the interrelationship among subjective public informativeness, attitudes, and behaviours according to different socio-demographic aspects. To meet the main objective of the paper, a representative public survey (N-804) on attitudes towards COVID-19 was conducted (at the end of 2020). The survey sought to explore individual self-protection measures, attitudes towards the dangerousness of the virus, the measures used by the government to combat the pandemic, and prevalent stereotypes and their implications on personal behaviour. The paper discusses the indicators, which are divided into separate blocks, on the basis of which the responses of the study participants are summed up and evaluated on a three-level (good, average, poor) rating scale, followed by correlation analyses on various socio-demographic parameters. The survey revealed that a higher proportion of Lithuanian society behaved responsibly, even being moderately informed and characterised by diverse attitudes.

Published: March 2023

This study was carried out to find a method to determine the seed germination ability (percentage) in the Turkish red pine (Pinus brutia Ten.) quickly and with high reliability. For this purpose, 82 seed lots of Turkish red pine were used, collected from different seed stands and orchards in different years. Since none of the seeds were folded, the germination ability was evaluated in a period between the 7th to 28th days. The seeds were divided into 4 groups (20–39.9%, 40–59.9%, 60–79.9%, 80–100%). Germination Percentage Index (GPI) are expressed with the mid-value of the related interval (e.g. GPI_30: germination ability between 20–39.9%). Four different germination percentage intervals describing the germination percentage was fitted with 11 different regression models. The best fit of these models was determined by 7 fitness measures. As a result, the current germination percentage increment reached the highest values on the 13th, 13th, 14th, and 13th day for the indexes of 90, 70, 50, and 30, respectively. Within this study, it has been revealed that germination percentages in Turkish red pine seed lots can be predicted 7 to 10 days in advance.

Published: March 2023

The hands are one of the most susceptible parts of the human body to bacterial infection. One way to maintain health is to maintain hand hygiene. Ethanolic rambutan rind extract from Aceh province has been studied in order to determine if it can inhibit bacterial growth. This research was conducted to determine the antiseptic activity of the ethanol extract of rambutan rind against Stahpylococcus aureus by determining the phenol coefficient and determining whether the ethanolic extract of Aceh’s rambutan rind can be formulated into a hand sanitizer gel. Antiseptic activity testing was performed using the Rideal-Walker method which was carried out in 5 dilutions (1:100, 1:150, 1:200, 1:250 and 1:300). The absorbance measurement showed that the extract could act as an antiseptic, at a concentration of 1% and at a dilution of 1:200 which has phenol coefficient of 1.67. The ethanolic extract of Aceh’s rambutan rind can be formulated in the form of a hand sanitizer gel using 1% Carbopol as gelling agent. The results showed that the gel was brown with a distinctive menthol odor and changed into a dark brown color after a cycling test. The evaluation results of all formulas appropriated the requirements except for adhesion parameter. The results of the irritation test showed that the volunteers did not experience any signs of irritation. The results of the preference test showed that the respondents liked the shape and aroma parameters but not the color parameter.

Published: March 2023

The production of biodegradable plastic from microorganisms has great potential as a substitute for conventional plastic. This study aims to isolate bacterial strains capable of polyhydroxyalkanoates (PHAs) production from the Kampung Jawa landfill land (KJLL) and characterize biopolymers. The bacterial strains were able to produce PHA using a mineral salt medium (MSM) with glucose as a carbon source. The qualitative screening of PHA-producing bacteria was conducted by Sudan Black and Nile Red. Of the 64 bacteria strains, only 41 were able to accumulate PHA in Sudan Black and Nile Red. The results showed that one bacteria the Coccobacillus strain had the highest color intensity for further characterization of PHA. The characterization of PHA by Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA) showed a melting temperature (Tm) of 101.54°C. X-ray diffraction (XRD) analysis revealed a crystalline structure with an index crystallinity (ICr) value of 15.82% for PHA. The results of the analysis proved that PHA was produced by bacteria isolate. This study suggests that this is the first report of the bacteria from the Kampung Jawa landfill producing PHA with good characteristics and potential biotechnology applications.
An Overview of the Mechanical and Tribological Characteristics of Non - Ferrous Metal Matrix Composites for Advanced Engineering Applications
Authors: Singh Wadhwa Amandeep , Chauhan Amit
Published: March 2023

The ever increasing service requirement of industries like automobile, aerospace, marine, infrastructure and transportation have evolved non-ferrous metal matrix composites with different combinations of ceramic and soft reinforcements which have resulted in the improvement of their tribo-mechanical properties as compared to an unreinforced alloy. Secondary reinforcements provide safe disposal of agro-industrial waste thereby reducing environmental degradation. The scanning electron micrographs reveals fairly uniform dispersal of reinforcement in metal matrix if proper conditions are maintained and porosity levels are found to be in acceptable range. The density, hardness, wear resistance, tensile strength, fatigue strength and impact strength of non-ferrous composites have been found to be either comparable or superior to an unreinforced alloy with minimum weight and cost. The purpose of current study is to explore the nonferrous composites and propose their application area based on material properties. An attempt has been made for indepth review on the effect of controllable process parameters on tribo-mechanical properties of the non-ferrous composites. The study concludes that non- ferrous composites with single or more than one reinforcement have superior tribo-mechanical characteristics making them suitable for design of high performance, low cost and low weight to strength ratio components.

Published: March 2023

Osteoarthritis (OA) is a degenerative disease of the knee joint caused by the formation of cracks within the collagen fibers of the articular cartilage. Current research is directed towards less invasive procedures for treating this degenerative disease using tissue engineering and 3D bioprinting. Therefore, it is crucial to obtain the exact shape of the damaged tissue, reconstruct the original shape of the tissue, and estimate the volume and area resulting from the wear of the contact surfaces. The study used the tibial plateau of a patient with OA that was removed during total knee arthroplasty, and the data was collected using a 3D scanner. After the reconstruction of the tibial plateau, an assessment of the area and volume of wear on the medial condyle of the tibia was performed, along with a FEM analysis of the real and approximate shape of the cartilage tissue. In this way, it is possible to simulate and create a patient-specific 3D model with a reconstructed wear volume, which can be highly attractive for future treatment strategies for cartilage damage or early stages of OA.

Background and Objective: Mobile phones have become an indispensable part of our daily life. Nomophobia (NMP) is an abbreviation for “no-mobile-phone phobia,” which defines apprehension faced by mobile phone users in its absence which leads them to become technically unable to communicate. Objective of the study is to determine the prevalence of NMP and its association with the demographic factors among medical students of a private medical college in Lahore.

Methods: A cross-sectional study was conducted among the medical students from first to final year classes from May to November 2021. A validated NMP questionnaire was used along with questions related to the sociodemographic profile and frequency of mobile phone usage by the respondents. The self-reported questionnaire was filled out by all the students who were present on the day of data collection. Data were analyzed by SPSS 20.

Results: Out of 646 medical students, 618 filled the questionnaire. Out of 618 respondents, 51.5% had moderate and 38.2% had severe NMP. Among sociodemographic variables, females (40.8%) had a statistically significant association with NMP (p = 0.027). Usage of mobile phones per day and disturbance in the students’ daily routine had a statistically significant association with the NMP (p = 0.029 and p = <0.001, respectively).

Conclusion: NMP is very common among medical students and females are more likely to experience this phenomenon. Frequent usage of mobile phones is directly related to NMP affecting the daily routine of the medical students.

Used cooking oil is an oil that has been used repeatedly in the process of frying food. Repeated use of cooking oil will cause a decrease in the quality of used cooking oil and if consumed will be harmful to health. The decrease in the quality of used cooking oil due to the formation of more double bonds in the structure of used cooking oil causes the oil to be more easily oxidized. The oxidation experienced by used cooking oil causes the quality of used cooking oil to decrease marked by the increasing value of peroxide number, free fatty acid content, water content and acid number of used cooking oil. One of the efforts that can be done to improve the quality of used cooking oil is to add an adsorbent to the used cooking oil. The added adsorbent serves to adsorb the impurities contained in the used cooking oil. One of the adsorbents that can be used is zeolite, zeolite can be used as an adsorbent because of the wide surface area of ​​zeolite which makes it easier for zeolite to adsorb chemical compounds on its surface. To test the quality of the oil can be done by measuring the peroxide number, free fatty acid content, water content and acid number. In this community service, training activities for refining used cooking oil will be carried out to the people of the Tanjung Gedong area, Tomang, West Jakarta. The link between PkM training in refining used cooking oil using natural zeolite for residents of the Tanjung Gedong area, West Jakarta and PkM flagship usakti, namely in the areas of regional development, ecogreen, and alternative energy.

Kegiatan penyediaan air bersih merupakan salah satu kebutuhan pokok bagi masyarakat, mengingat air bersih adalah faktor penting dalam kehidupan dan kesehatan masyarakat. Semakin bertambahnya populasi penduduk ditunjang dengan aktifitas ekonomi yang semakin kompleks, juga berdampak pada strategi pelayanan kebutuhan akan air bersih dan pemaksimalan usaha untuk menghadirkan sarana air bersih. Masalah air bersih tidak hanya hadir di daerah-daerah terpencil yang belum tersentuh pembangunan, daerah perkotaan dengan jaringan infrastruktur PAM yang sudah memadai pun terkadang masih terkendala dengan aktifitas pencemaran air dan penggunaan air berlebihan yang tidak efektif dan efisien. Desa Sungai Dayo Kec. Bahar Utara Kab. Muaro Jambi, memiliki permasalahan air yang kotor dengan kandungan mangan dan besi yang tinggi. Selain tercemar limbah, hasil penelitian menunjukkan bahwa air tanah di daerah tersebut bersifat payau dan mengandung pengotor unsur mangan, besi, dan fluoride tinggi yang tidak baik untuk kesehatan, terutama kesehatan gigi. Berkaitan dengan hal tersebut diperlukan aplikasi teknologi tepat guna untuk memaksimalkan potensi air yang sudah tersedia, berikut peluang untuk memanfaatkan air bekas pakai dalam aktivitas untuk meningkatkan taraf hidup dan perekonomian warga.

The purpose of this study is to examine the effect of audit quality proxied by the size of the auditor, auditor industry specialization and audit tenure on earnings management. Earnings management is proxied by discretionary accruals. This study uses three control variables, which are firm size, operating cash flow ratio, and leverage. This study uses secondary data derived from the financial statements of listed companies on the Indonesia Stock Exchange from 2017-2019. Based on the purposive sampling method we obtain 366 observations, and the technique for examining the hypothesis is multiple regression analysis. The results show that audit quality has no significant effect on earnings management. However, this study finds that Big 4 audit quality and auditors of industry specialization moderated the relationship between cash flow from operations and earnings management, while leverage moderates the relationship between Big 4 audit quality and earnings management.

This work investigates the impact of elevation on terrain-induced slugging in a riser system. Fluid compositions were modeled with multiflash and exported to OLGA in a readable PVT Table File. Pipeline materials and properties with geometry of different elevation were modeled in OLGA to develop a flowline model. Two geometries (1 and 2) of different elevations were defined to establish their effect on accumulated liquid volume flow, surge liquid volume, slug length, number of slugs and slug density. The result shows that Geometry 1 with a total elevation(height)of 450 ft has a total liquid volume flow of 10.1058 ft3/s and Geometry 2 with a total elevation(height) of 300 ft has a total liquid volume flow of 0.197822 ft3/s for the same time of 2473.99 seconds. Also, Geometry 1 has a surge liquid volume of 543.4608484 ft3 at a drain rate of 0.20843960 ft3/s and Geometry 2 with a surge liquid volume of 210.7395 ft3 at a drain rate of 0.23892 ft3/s. There was no slug length and number of slugs in pipe of Geometry 1 while Geometry 2 has a slug length of 531.78 ft indicating severe slug in Geometry 2 system of different elevation. The slug density of Geometry 2 system was twice that of Geometry 1. Change in the elevation for the geometries has shown a significant effect on terrain–induced slugging in the pipe-riser system.

Motor induksi merupakan salah satu bagian terpenting dalam dunia industri saat ini, sehingga jika sebuah motor induksi mengalami kerusakan dapat mempengaruhi proses produksi. Oleh karena itu, gangguan-gangguan yang ada pada motor induksi harus dapat diprediksi ataupun dideteksi sedini mungkin. Salah satu penyebab kerusakan pada bearing adalah kurangnya pelumasan sehingga dapat menyebabkan peningkatan suhu pada motor, suara bising, vibrasi dan timbulnya bunga api sehingga dapat menyebabkan kerusakan pada bagian lain motor induksi. Maka penulis akan melakukan penelitian dengan menggunakan empat parameter berbeda yakni arus asut, vibrasi, dan suhu pada motor Kompresor Udara yang perlakuan pemeliharaannya dalam pelumasan ulang dilakukan berbeda. Dalam penelitian ini didapatkan bahwa apabila pelumasan pada bearing tidak dirawat dengan baik maka nilai vibrasi sangat tinggi berada di angka 23 hingga 24 mm/s, arus starting sendiri mengalami kenaikan hingga 8 kali arus nominal dimana hal tersebut dapat menyebabkan rugi tegangan yang besar, arus steady state sendiri untuk motor induksi yang pelumasan bearingnya kering arusnya berada di atas arus nominal motor yakni 133% dari arus nominal, dengan keringnya pelumasan pada bearing motor induksi gesekan tidak dapat diminimalisir sehingga suhu dari motor meningkat di mana diperoleh data kenaikan suhu motor induksi selama 5 menit kerja motor sebesar 2 kali suhu awal motor yakni 74.3⁰ C dan hal tersebut dapat membahayakan motor induksi itu sendiri, maka dapat diambil kesimpulan semakin kurangnya pelumasan pada bearing motor induksi hal tersebut mempengaruhi arus starting, arus steady state, suhu, dan vibrasi sehingga dapat dideteksi sedini mungkin apabila motor induksi mengalami kekurangan pelumasan pada bearing motor induksi.

As a country with the first largest Muslim population in the world, it should be able to make zakat funds paid by muzakki to address the problem of poverty in Indonesia. However, the Muslim community is still reluctant to channel their zakat funds to official zakat institutions. They prefer to pay their zakat to ustadz or mosques whose financial reports are still informal. This is also due to zakat institutions that have not adopted good governance and institutional inconsistencies in providing services and poor management. the purpose of the influence of governance, internal control, and institutional culture affects fraud prevention, and fraud prevention can mediate the relationship between governance, internal control, and institutional culture on the performance of zakat institutions. the method in this research is qualitative by distributing questionnaires. The difference between this research is the addition of internal control variables and institutional culture which are expected to affect the performance of zakat institutions. The results of this study are that internal control affects fraud prevention, fraud prevention affects the performance of zakat institutions and fraud prevention can mediate the relationship between internal control and zakat institution performance. This is because the internal controls that have been carried out zakat institutions have carried out the process of selecting human resources efficiently and effectively. besides that, the institution has given appreciation to employees for their performance and has committed to integrity by implementing applicable policies and procedures to improve the performance of zakat institutions.
