Ureteroneocystostomy for treatment of struvite urolithiasis in a ferret
Authors: Laminette Peter J. , Trout Nicholas J. , Noonan Brendan , Viani Emily
Published: May 2023

OBJECTIVE

To assess the clinical outcome of a ferret undergoing a ureteroneocystostomy for treatment of urolithiasis.

ANIMAL

A 10-month-old spayed female ferret.

CLINICAL PRESENTATION, PROGRESSION, AND PROCEDURES

The ferret was evaluated for straining to urinate and defecate, hematochezia, and a rectal prolapse. Plain radiographs revealed large cystic and ureteral calculi. Clinicopathologic analyses indicated the ferret was anemic with an elevated creatinine concentration. Exploratory laparotomy defined bilateral ureteral calculi that were unable to be successfully moved into the bladder. A cystotomy was performed to remove a large cystic calculus. Serial abdominal ultrasonographic examinations showed progressive hydronephrosis of the left kidney and persistent pyelectasia of the right kidney secondary to bilateral ureteral calculi. This confirmed a left ureteral obstruction secondary to the distal calculus while the right ureter remained patent.

TREATMENT AND OUTCOME

A ureteroneocystostomy was performed to allow for left renal decompression. The ferret recovered well despite worsening hydronephrosis of the left kidney in the perioperative period. The ferret was discharged from the hospital 10 days after initial evaluation. At 3-week follow-up, abdominal ultrasonography confirmed resolution of hydronephrosis and ureteral dilation of the left kidney and ureter.

CLINICAL RELEVANCE

A ureteroneocystostomy successfully allowed renal decompression and ureteral patency in a ferret with urolithiasis. To the authors’ knowledge, this is the first time this procedure has been reported in a ferret for treatment of a ureteral calculus obstruction and may result in good long-term outcome.

Published: May 2023

OBJECTIVE

To investigate the CT features of cavitary pulmonary lesions and determine their utility to differentiate malignant from benign lesions.

ANIMALS

This retrospective study included cases from 5 veterinary medical centers between January 1 2010, and December 31, 2020. Inclusion criteria included having a gas-filled cavitary pulmonary lesion on thoracic CT and definitive diagnosis by either cytology or histopathology. Forty-two animals (27 dogs and 15 cats) were included in this study.

PROCEDURES

Medical records systems/imaging databases were searched, and cases meeting inclusion criteria were selected. The CT studies were interpreted by a third-year radiology resident, and findings were reviewed by a board-certified veterinary radiologist.

RESULTS

7 of the 13 lesion characteristics investigated were not statistically associated with the final diagnosis of the lesion, whereas 6 were statistically associated. Those that were associated included the presence of intralesional contrast enhancement, type of intralesional contrast enhancement (heterogenous and homogenous analyzed separately), presence of additional nodules, wall thickness of the lesion at its thickest point, and wall thickness at the thinnest point.

CLINICAL RELEVANCE

Results from the present study showed that thoracic CT imaging of cavitary pulmonary lesions can be used to further refine the list of differential diagnoses. Based on this data set, in lesions that have heterogenous contrast enhancement, additional pulmonary nodules, and wall thickness > 40 mm at their thickest point, it would be reasonable to consider malignant neoplastic disease higher on the list of differentials than other causes.

Published: May 2023

OBJECTIVE

To assess and compare the quality of smartphone ECG tracings to standard (base-apex) ECG tracings and assess agreement of ECG parameters between smartphone-based ECG and standard ECG.

ANIMALS

25 rams.

PROCEDURES

The rams were consecutively examined with standard ECG and smartphone-based ECG (KardiaMobile; AliveCor Inc) after physical examination. ECGs were compared for quality score, heart rate, and ECG waves, complexes, and intervals. Quality scores were based on the presence or absence of baseline undulation and tremor artifacts using a 3-point scoring system (lowest possible = 0; highest possible = 3). A lower score was indicative of a better-quality ECG.

RESULTS

Smartphone-based ECGs were interpretable in 65% of cases, while 100% of standard ECGs were interpretable. Standard ECG quality was superior to smartphone-based ECG quality, with no agreement in the quality between devices (κ coefficient, –0.0062). There was good agreement for heart rate with mean difference 2.86 beats/min (CI, –3.44 to 9.16) between the standard and smartphone ECGs. Good agreement was observed for P wave amplitude with mean difference 0.02 mV (CI, –0.01 to 0.05), QRS duration with mean difference –10.5 ms (CI, –20.96 to –0.04), QT interval with mean difference –27.14 ms (CI, –59.36 to 5.08), T wave duration with mean difference –30.00 ms (CI, –66.727 to 6.727), and T wave amplitude with mean difference –0.07 mV (CI, –0.22 to 0.08) between the 2 devices.

CLINICAL RELEVANCE

Our findings indicate good agreement between standard and smartphone ECG for most parameters, although 35% of smartphone ECGs were uninterpretable.

Authors: Xhaferraj Ervenila Musta
Published: May 2023

This work introduces a new integral transform for functions of exponential order called “NE integral transform”. We prove some properties of NE -transform. Also, some applications of the NE- transform to find the solution to ordinary linear equation are given. The relationships of the new transform with well-known transforms are characterized by integral identities. We study the properties of this transform. Then we compare it with few exiting integral transforms in the Laplace family such as Laplace, Sumudu, Elzaki, Aboodh and etc. As well, the NE integral transform is applied and used to find the solution of linear ordinary differential equations.
Evaluation of Gait in Albanian β-thalassemia Patients
Authors: Pano Genti
Published: May 2023

One of the most prevalent genetic diseases in the world is beta thalassemia. Hemoglobin synthesis is decreased by the blood condition beta thalassemia. Patients with thalassemia exhibit a range of bone problems, including as spinal deformities, osteopenia and osteoporosis, as well as growth failure. This study’s main goal was to evaluate gait and balance in Albanian β-thalassemia patients. In this study, 18 participants aged 17 to 29 years old (5 males and 13 females) from three distinct epidemiological cities in Albania took part. Gait analysis was performed using “T&T medilogic medizintechnik gmbh” wi-fi insoles. “General Gait Parameters”, results of the “Effective Foot Length, left [%]” parameter mean results [67.59%], reveals approx a 2% difference compared with the relative normative mean [69.7%]. Also, “Effective Foot Length, left [%]” mean results [65.49%], reveals approximately a 3.5% difference compared with the relative normative mean [69.7%]. “General Gait Parameters”, data comparisons revealed statistically significant differences between “is” and “nom.” measurements for the following variables: “Rel Double Step Length”, “Double Step Duration”, “Effective Foot Length Right” and “Width Of Gait Right” (p<0.005). Results for the rest of the variables shwed a not statistically significant difference. The aim of the study was to assess the gait parameter in Albanian individuals with thalassemia. Based on the result of the “General Gait Parameters”, data reveal a difference in the % of the average gait line which is related to effective distribution in the insole length showing a specific indication of insecure gait. According to the findings, gait issues are a significant health issue for beta thalassemia patients which are most likely caused by disease-related side-effects such high calcium levels after blood transfusions, inactivity caused by insufficient muscle mass, and all other health-related disease conditions. It is advised that the gait analysis exam to be included in their regular health check-ups. Future studies should be conducted involving larger ß-thalassemia patients take into account the unique state of this category to better evaluate the gait problems related with general static and dynamic posture problems. Clinicians’ health specialists and rehabilitation experts when planning B-Thal rehabilitation programs sholud use gait analysis exam as a regular health check-up.
Determinants of Patient Satisfaction with Health Care: A Literature Review
Authors: Kalaja Rezarta
Published: May 2023

This research paper aims to explore the field of patient satisfaction in health care, by performing a literature review on existing healthcare articles that analyse determinants of patient’s satisfaction and theories on patient satisfaction assessment. Patient satisfaction is one of the most important factors to determine the success of health care providers. Determining the exact definition, determinants and characteristics of patients that influence satisfaction, as well as different theories on satisfaction, are highly discussed elements in the literature for a long period of time. The research instrument was a literature review by combining different view from many researchers. The literature was searched in databases such as Emerald, Medline/PubMed, Web of Science, ScienceDirect, Scopus. Patient satisfaction appears to play an important role in evaluation of service quality. From the literature review, it was observed that the main determinants of patient satisfaction were the demographic characteristics, expectations and experiences of the patients. Communication is also an extremely important element that affects patient satisfaction. Other research should be conducted to delve even more into this very important area of health care.
Predictors of Adolescents’ Antisocial Behavior in Southeastern Nigeria: Exposure to Armed Conflict and Physical Punishment at Home
Authors: Anih Anthony S. , Söderberg Patrik , Björkqvist Kaj
Published: May 2023

Despite extensive studies on the relationship between armed conflict and behavioral problems among adolescents, the micro-level mechanisms through which the former influences the latter are not well understood. The current study examines the relationship between exposure to the Fulani herdsmen attacks among Igbo adolescents in Southeastern Nigeria and antisocial behavior. Using a mediation analysis, it was examined whether physical punishment mediated the relationship. A sample of 385 secondary school students (227 girls, 157 boys; Mage = 16.3; SD = 1.35) completed a questionnaire during class. It was found that exposure to the Fulani herdsmen attacks predicted antisocial behavior among the adolescents, and the effect was weakly mediated by the experiences of physical punishment at home. The findings suggest that living in an environment of armed conflict may lead to increased levels of antisocial behavior in adolescents.

Published: May 2023

The purpose of this study is to examine the factors that influence financial statement fraud through the fraud hexagon theory. The population in this study are all mining sector companies listed on the Indonesia Stock Exchange which are included in the company sample criteria in the 2016 to 2019 period, namely as many as 32 companies. Sampling was carried out by purposive sampling technique and 100 units of analysis were selected after the data outlier technique was carried out. The measurement used to calculate financial statement fraud is earnings management. In addition, the software used is SPSS IBM 24. The results show that the financial target and the nature of the industry have a significant positive effect on financial statement fraud, while the external pressure, change of directors, collusion, and change of auditors have no significant effect on fraudulent financial statements. Meanwhile, the CEO duality variable has a negative but not significant effect on financial statement fraud. The limitation of this research is that the collusion proxy is measured using a joint project with the government, so suggestions for further research are expected to use other proxies such as political connections or state-owned enterprises.
Creating a watermill through STEAM activities for preschool children in the schoolyard
Authors: Skaraki Evaggelia
Published: May 2023

STEAM (Science, Technology, Engineering, Arts and Mathematics) initiatives engage in classroom and schoolyard activities in early childhood education. In early childhood, learning through play provides children with the resources they need for an enjoyable learning environment, especially when the activities take place in the schoolyard, as this is where children can better concentrate and, at the same time, increase their creativity. This work investigates whether preschool children can create watermills through STEAM activities in the schoolyard. Thirty-four children aged 4-6 years participated in the research, and the results were encouraging as the children liked that the activities were outside. At the same time, the teachers were worried if they would be able to support such activities. Preschoolers have a spontaneous disposition toward science with a sense of curiosity and creativity. More research needs to be done on out-of-class activities with the STEAM app, and this training should be incorporated in all kindergartens.

Children as Participants in the Liberation Struggle: Lydia Shaketange’s Walking the Boeing 707 (2008) and Ellen Namhila’s The Price of Freedom (1997)
Authors: Mlambo Nelson , Nahole Martha
Published: May 2023

This paper explores how two Namibian female-authored autobiographical texts represent children as active participants in the liberation struggle. It interrogates whether children are portrayed as agents in the liberation struggle or simply objects of pity and victims in the exilic environment. The findings in this study reveal that during the liberation struggle, children were active agents and subjects. As such, the study debunks the portrayal of children as passive victims of the exilic environment, as often portrayed in some literary and academic texts. Although, to some extent, they suffer victimisation and the brutality of the struggle, the child characters in the autobiographies have proven agency by taking part in activities that enable the country to attain independence, for instance, the maintenance of the camps, working as teachers and material developers, and as nurses. It has further been revealed that children are intelligent and perseverant beings. Implicitly, they are portrayed as compassionate, assertive, full of endurance, as well as “s/heroes.” Therefore, the study re-versions the representation of children simply as weak, passive, and objects and victims of life’s historical events. The paper also argues that issues of child subjectivity in the struggle are rarely foregrounded in Namibian literary studies; hence this study has proven to be a platform to interrogate the conventional objectification of child characters in the autobiographical works of Shaketange and Namhila.
International Labour Organisation Convention No. 138, Article 7 and its Implementation in South African Municipal Laws: Suggested Policy Changes
Authors: Mavunga Rufaro Audrey
Published: May 2023

The purpose of this article is to examine the implementation of Article 7 of Convention No. 138 in the municipal laws of South Africa. The regulation of light work in South Africa is complex because there is no legislation that defines or even refers to light work by children between the ages of 12 and 15. Children below the age of 15 years can only undertake work for the purposes of fundraising and charity and cannot be employed for remuneration. The relevant legislation does not provide children with adequate opportunities to undertake work that could be beneficial for children.
Covid-19 Vaccine Hesitancy among Youth in South Africa: A Narrative Review
Authors: Moodley Janice , Oppong Seth
Published: May 2023

Vaccine hesitancy emerged as a highly contentious public health concern during the Covid-19 pandemic. Despite the pandemic becoming endemic, a proactive reflection on vaccine hesitancy among youth in South Africa is essential for understanding this cohort’s vaccine behaviours for informing future public health interventions. Using a narrative review, we explore existing literature on vaccine hesitancy among youth in South Africa. We highlight existing literature on youth vaccine hesitancy using international and local research studies. This was necessary since our findings showed that there is a dearth of evidenced-based literature that has explored vaccine hesitancy among youth in the South African context. This review was challenged by the different age ranges that were used to define youth in different research studies. We conclude with recommendations for mitigating vaccine hesitancy in South African youth.

Authors: Nurgaliev Ian , Eskander Youssef , Lis Karolina
Published: May 2023

The logistics and delivery industry is facing challenges such as high transportation costs, difficulty in meeting customer demands, and environmental concerns. However, the integration of drone and autonomous vehicle technology can address these challenges by reducing transportation costs, increasing speed and reliability of delivery, and improving efficiency. The use of drones and autonomous vehicles can bring significant benefits such as increased efficiency, cost savings, improved safety, increased accessibility, and real-time tracking. Despite the potential benefits, there are still regulatory, technical, and financial barriers to overcome before a widespread adoption of these technologies. The use of drones and autonomous vehicles in the logistics and delivery industry is rapidly growing, with companies like Amazon, UPS, DHL actively experimenting with the use of these technologies. However, there are several challenges and limitations that must be overcome before they can be widely adopted, such as safety and regulatory requirements, weather and environmental conditions, battery life and range, navigation, and public perception.
Dielectric metal/metal oxide nanocomposites: modeling response properties at multiple scales
Authors: Henderson Brett , Adluri Archita , Paci Irina
Published: May 2023

Nanocomposites with metallic inclusions show great promise as tunable functional materials, particularly for applications where high permittivities are desirable, such as charge-storage. These applications strain quantum mechanical computational approaches, as any representative sample of the material includes hundreds if not thousands of atoms. Many continuum methods offer some predictive power for matrix-inclusion composites, but cannot be directly applied to composites with small inclusions, for which quantum and interfacial effects dominate. Here, we develop an adjustable finite element approach to calculate the permittivities of composites consisting of a metal-oxide matrix with nanometer-scale silver inclusions, by introducing an interfacial layer in the model. The approach involves solving the Laplace equation with Dirichlet and Neumann boundary conditions. We demonstrate that such a continuum model, when appropriately informed using quantum mechanical results, can capture many of the relevant polarization effects in a metal/metal oxide nanocomposite, including those that contain arbitrarily-small inclusions, at a fraction of the computational cost of performing the full quantum mechanics.
Metric geometry tools for automatic structure phase map generation
Authors: Vaddi Kiran , Li Karen , Pozzo Lilo D
Published: May 2023

Extracting a phase map that provides a hierarchical summary of high-throughput experiments is a long-standing bottleneck for the modern goal of achieving automation and acceleration in material discovery. A phase map that underpins the inherent properties of materials is typically denoted using a composition-structure map but can be extended to other relevant parameters such as synthesis. This paper describes a computational statistical tool to efficiently obtain a phase map from multi-scale experimental measurement profiles obtained from high-throughput measurements. We motivate the construction of a phase map as the problem of learning the underlying metric geometry defined by a set of templates in infinite-dimensional function spaces. We provide a statistical analysis tool to obtain a phase map as an asymptotic of the diffusion of resulting distance functions on the composition. Using examples from small-angle X-ray scattering experiments of polymer blend systems, we show that learned metric geometry can efficiently differentiate ordered phase regions with shifted, missing, and broad Bragg peaks along with features related to non-Bragg behavior of soft-matter systems. The metric geometry allows us to define a shape distance between scattering profiles invariant to phase-independent transformations thus valuable for obtaining a phase map. We also apply the methodology to benchmark experimental diffraction data to showcase potential utility and broad applicability.

Comprehensive de novo glycan sequencing remains an elusive goal due to the structural diversity and complexity of glycans. Present strategies employing collision-induced dissociation (CID) and higher energy collisional dissociation (HCD)-based multi-stage tandem mass spectrometry (MSn) or MS/MS combined with sequential exoglycosidase digestion are inherently low-throughput and difficult to automate. Compared to CID and HCD, electron transfer dissociation (ETD) and electron capture dissociation (ECD) each generate more cross-ring cleavages informative about linkage positions, but electronic excitation dissociation (EED) exceeds their information content and is also applicable to analysis of singly charged precursors. Although EED can provide extensive glycan structural information in a single stage of MS/MS, its performance has largely been limited to FTICR MS, and thus it has not been widely adopted by the glycoscience research community. Here, the effective performance of EED MS/MS was demonstrated on a hybrid Orbitrap-Omnitrap QE-HF instrument, with high sensitivity, fragmentation efficiency, and analysis speed. In addition, a novel EED MS2-guided MS3 approach was developed for detailed glycan structural analysis. Automated topology reconstruction from MS2 and MS3 spectra could be achieved with a modified GlycoDeNovo software. We showed that the topology and linkage configurations of the Man9GlcNAc2 glycan can be accurately determined from first principles based on one EED MS2 and two CID-EED MS3 analyses, without reliance on biological knowledge, a structure database or a spectral library. The presented approach holds great promise for autonomous, comprehensive and de novo glycan sequencing.

Air pollution is an epochal concern, particularly in urban areas, and is linked to combustion processes 1 . The emission of nitrogen oxides (NOx) constitutes a critical environmental problem, and it can affect severely human health2,3,4 . At ambient temperature and pressure NOx decomposition is thermodynamically favoured; however, this process is kinetically inhibited, owing to a high activation energy5,6 . To date, no reported catalysts have had the required properties to lower the activation energy of this process without the help of coreacting agents and high temperatures7,8,9 . Here, we show that NO conversion to molecular nitrogen can be achieved at room temperature in the presence of O2 and H2O vapour, and in the absence of any further reducing agent, using iron-based Metal-Organic Frameworks (MOFs). Further, we demonstrate that MOFs work similarly to enzymes, but are stable in environments unfriendly to living matter. These findings open large perspectives on the solution of stringent problems in chemistry, such as the removal of pollutants or the activation of highly stable molecules.
Density Functional Theory and Machine Learning for Electrochemical Square-Scheme Prediction: An Application to Quinone-type Molecules Relevant to Redox Flow Batteries

Published: May 2023

Proton-electron transfer (PET) reactions are rather common in chemistry and crucial in energy storage applications. How electrons and protons are involved or which mechanism dominates is strongly molecule and pH dependent. It is the nature of the participants in the reaction that dictates how electrons and protons are involved and which mechanism dominates. Quantum chemical methods can be used to assess redox potential and acidity constant values but the computations are rather time consuming. In this work, supervised machine learning (ML) models are used to predict PET reactions and analyze molecular space. The data for ML have been created by density functional theory (DFT) calculations. Random Forest Regression models are trained and tested on a dataset that we created. The dataset contains more than 8200 organic molecules that each underwent a two-proton two-electron transfer process. Both structural and chemical descriptors are used. The HOMO of the reactant and LUMO of the product participating in the oxidation reaction appeared to be inversely associated with \oxE. Trained models using a SMILES-based descriptor can efficiently predict the pKa and redox potential with a mean absolute error of less than 1 and 66 mV, respectively. High prediction accuracy of $R^2 > 0.76$ and $> 0.90$ was also obtained on the external test set for redox potential and pKa, respectively. This hybrid DFT-ML study can be applied to speed up the screening of quinone-type molecules for energy storage and other applications.

EFFECT OF SILICON-CONTAINING FERTILIZERS ON TOMATO AND CUCUMBER YIELDS UNDER CONDITIONS OF LOW-VOLUME HYDROPONICS
Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, LAPUSHKIN V.M.
Published: May 2023

The effect of different silicon-containing fertilizers (NanoKremniy, Siliplant, biostimulant “Bona Forte” and sodium silicate) on the growth, development and yield of hybrids of cucumber Byorn F1 and tomato Merlis F1 was studied under conditions of low-volume hydroponics. The studies showed that carrying out foliar feeding of tomato resulted in earlier production and reliable yield increase of 6.5–8.0 kg/m2 by increasing the number of fruits by 10–12% and the average fruit weight by 18–23%. Using of silicon-containing fertilizers in the cultivation of cucumber in the winterspring turnover increased the area of the assimilation apparatus of plants, the number of formed fruits, and their average weight. The quality of the yield improved by increasing the dry matter content and by decreasing the content of nitrate nitrogen in fruits from 382 to 181–230 mg/kg. The maximum increase in cucumber yield of 5.3–6.5 kg/m2 was achieved with the use of a siliplant a nd a silicon-containing biostimulant.

Published: May 2023

The results of the study of 30 flax samples of different ecological and geographical origin from the collection of the N.I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR) are presented. The varieties of the Russian selection 14, Chinese 6, Ukrainian 5, French 4, Belarusian 1 have been investigated. The influence of genotypes and weather conditions on the manifestation of economic traits by multivariate analysis of variance has been established. Field studies were conducted in the sub taiga zone of the Tomsk region in 2015-2017. Natural and climatic conditions met the requirements for the cultivation of fiber flax. By total and technical stem length the best varieties of the Chinese selection Heiya 4 (K-8485), Sxy 7 (K-8689), the Russian hybrid Tomsk 16 * Success (K-8544), the French variety Drakkar (K-8493), the Ukrainian Glazur (K-8695), 66-72 and 60-66 cm respectively, were significantly higher than the standard Tomsk 16. According to the fiber content in the technical part of the stems (38-40%) the following varieties were the leaders: the Russian selection P-3989 (K-8672), A-236 (K-8692), M-249 (K-8693), the French selection Alizee (K-8494), Agatha (K-8492), Melina (K-8495), and the Ukrainian selection Vruchy (K-8694), were significantly above the Tomsk 16 standard. By the fiber mass (91-104 mg) the French varieties Drakkar (K-8493) and Alizee (K-8494), the Ukrainian varieties Vruchii (K-8694) and Glazur (K8695), the Russian varieties A-236 (K-8692) and M-249 (K-8693) reliably exceeded the Tomsk 16 standard by 6-44 mg. The flax varieties of the Russian selection P-3989 (K-8672), Dobrynya (K8504), A-236 (K-8692), the Chinese Heiya 4 (K-8485), Heiya 13 (K-8486), Tyy 13 (K-8687), the French Agatha (K-8492), Drakkar (K-8493), Alizee (K-8494), Melina (K-8495), and the Ukrainian Gladiator (K-8505) and Vruchiy (K-8694) were recognized as promising and were included in the breeding process as male seed parents. The resulting hybrid material has been on trial in the selection nursery from 2017 and the second year of breeding from 2021.

Background/Aim: Post-operative delirium, which usually develops in geriatric patients, also causes an increase in mortality and morbidity for various reasons, such as difficulty in compliance with treatment. Estimating the effects of the anesthesia method on delirium contributes to the prevention of possible complications. In this study, effects due to use of different anesthesia methods on the post-operative delirium development in geriatric patients who underwent orthopedic surgery were investigated. Methods: In our retrospective cohort study, scanning of the patient files was performed for 276 patients who were older than 65 years and who had undergone surgery for lower extremity fractures in Malatya education and research hospital, orthopedics department between May 1, 2022 and October 15, 2022. Demographic data, comorbid conditions, anesthesia type, lengths of surgery, and level of delirium development were recorded for each scanned patient. Results: In our study, 201 patients were included. The mean age of the patients was 74.1 (7.3) (min–max: 65–98); 133 (66.2%) were female, and 68 (33.8%) were male. It was noticed that patients who had undergone regional anesthesia developed a significantly smaller rate of delirium development (8.1%) compared to those who had received general anesthesia (20.6%; P=0.012). Ages (P<0.001), lengths of surgery (P<0.001), and lengths of hospitalization stays (P<0.001) were significantly higher in patients with delirium compared to those without. Conclusion: Based on the data obtained in this study, it was concluded that to reduce the risk of delirium development after orthopedic surgery, regional rather than general anesthesia should be selected, and the time of hospitalization stay should be minimized.

Against the detrimental effects of ionizing radiation, time, distance, and shielding are the three most significant protective methods. Lead is the material of choice for shielding, particularly for personal protective equipment. However, lead's density, rigidity, and toxicity are significant disadvantages. In recent years, tungsten-containing rubber (TCR) and other lightweight, flexible, and non-toxic shielding materials have emerged as viable alternatives to lead. The purpose of this study is to examine the X-ray absorption capacity of TCR material, which can serve as an alternative to lead-based personal protective equipment. Using GAMOS simulation, radiation absorption characteristics for 11 different X-ray energies ranging from 30 to 1000 keV were obtained and compared with Phy-X/PSD data. While the MFP value produced from the GAMOS code for the TCR with 100 keV energy X rays was 0.0204 cm, the Phy-X/PSD value was 0.0296 cm. The HVL value of the TCR material for X-rays with an energy of 100 keV was 0.021 cm for Phy-X/PSD and 0.014 cm for GAMOS. It has been observed to provide excellent radiation protection against X-rays in the diagnostic imaging field. By providing greater flexibility than lead shielding materials, TCR can play a crucial role in decreasing radiation exposure.

Fokus dari penelitian ini adalah karakteristik dimensi utama kapal pukat cincin yang  berpangkalan di Pelabuhan Perikanan Pantai (PPP) Belang Minahasa Tenggara. Penelitian ini bertujuan untuk mengetahui rasio atau perbandingan ukuran utama kapal (L/B, L/D, dan B/D),  hubungan antar-ukuran utama kapal (L vs B, L vs D, dan B vs D), dan hubungan ukuran utama kapal (L) dengan kapasitas muat kapal (GT) serta daya mesin pendorong kapal (HP). Metode analisis data dilakukan dengan menggunakan analisis deskriptif melalui tabulasi silang dan penyajian data dalam bentuk kurva hubungan perbandingan ukuran utama kapal, hubungan antar ukuran utama kapal, serta hubungan antara ukuran utama kapal (L) dengan kapasitas muat  (GT) dan daya mesin pendorong kapal (HP).  Hubungan ini dianalisis dengan menggunakan analisis regresi dengan model matematis: Y = a + bX, di mana a (intercept) dan b (koefisien regresi), serta Y dan X  disesuaikan dengan variabel yang akan dianalisis. Untuk menghitung nilai a dan b dari setiap hubungan digunakan aplikasi ‘Curve Expert’. Hasil penelitian ini menunjukkan bahwa perbandingan dimensi utama kapal pukat cincin di PPP Belang masih belum sesuai dengan standar nilai yang ajukan oleh Fyson (1985), di mana nilai L/B dan nilai L/D lebih besar sedangkan nilai B/D  lebih kecil. Terdapat hubungan positif antar-ukuran utama kapal (L/B, L/D, B/D) dan antara ukuran utama kapal (L) dengan kapasitas muat (GT) dan daya mesin (HP).

La falta de conocimiento detallado sobre la diversidad, distribución y biología de los peces de la provincia de San Juan, junto con la siembra permanente de especies exóticas como los salmónidos, sumado a la actividad antrópica asociada a humedales, atentan contra la conservación de la riqueza ictícola. Hasta la fecha para San Juan solo existe un único reporte de P. laticeps colectado en el departamento Zonda en el Área Natural Protegida Presidente Sarmiento. Se reportan ejemplares de P. laticeps en los departamentos: Jáchal, Ullum, Rivadavia, Zonda y Calingasta ampliando sudistribución a su extremo más occidental hacia los andes centrales de Argentina.
Prevalence of hemorrhagic septicemia in dromedary camel (Camelus dromedarius) of some selected farms at Benadir region, Somalia
Authors: BARRE Abdirahman
Published: May 2023

Pasteurellosis (Hemorrhagic septicemia) is a common respiratory Disease of camel that is an acutely fatal disease caused by Pasteurella multocida type A or several serotypes of Mannheimia hemolytic, which also affect other animals. The disease had shown to spread between animals, across herds, and to humans. Meaning that the disease is Zoonosis. The study aimed at the establishment of seroprevalence of Pasteurellosis in some selected Districts of camel rearing in the Benadir Region. It was a cross-sectional study, where the study population was purposively chosen to consist of animals taken within three sub-Districts of Benadir Region, namely Sub-District (Daynile Township), Sub-District (Yaaqshid) Sub-District (kaxda). This was because they normally handle many camels in a day, thus making it easy for the investigator to access the required number conveniently; it was also assumed that data collected from these for-slaughter camels was representative of the situation in the sub-District/county. A total of one hundred and sixty camels were tested using four serological tests: Rose Bengal Plate Test (RBPT),) and Complex Fixation Test (CFT). The serological tests were purposively chosen to increase the chances of picking positive cases and also to compare their sensitivities, with respect to camel serum, since they were originally meant for use on bovine serum. Blood samples (15 ml) were collected for serum harvesting from the jugular veins of the animals as they were waiting to be examined. Rose Bengal plate test and CFT were run at a laboratory within the department of Veterinary Medicine, University of Horsed, 21 October campus; serum samples having been transported in a cool box. On average, out of an overall total of 300 serum samples tested, 180 samples were selected as sample procedures and were given eleven (11) positive results, amounting to a prevalence of 6.67%. For the three Districts, respective prevalence (averaged from the two (2) serological tests run) were: 7% (3/50) for Yaqshiid; 8% (3/60) for Deyniile, and 10% (3/70) for Kaxda. When sensitivities of the two (2) serological tests were compared, there was no significant difference between them, with respect to the picking of positive cases (p=0.05), The study has demonstrated presence of Pasterolosis in camels in the Benadir Region and the authors are, recommending the usage of RBPT and CFT as a screening test since they are cheap, quick, and easy to carry-out. Any of the other three involving tests can then be used if one wants to establish respective titers. Therefore, further detailed investigation needs to be conducted so as to understand specific etiological agents causing pasteurellosis in camels and can be instituted to optimize the benefit obtained from the camel sector.

This study aims to determine the possible relationship between the levels of Kallistatin and the severity of liver injury in rats that were exposed to carbon tetrachloride (CCl4). According to the results, serum ALT, AST, LDH, GGT and Collagen-I and Collagen-III levels in rats in the severe group were higher than control. Histopathological examination of rats in injury groups showed severe morphological changes that were resulted in cell dissociation and disruption of the liver lobe architecture in the liver parenchyma of rats that received CCl4. Kallistatin serum level decreasing respectively in M1, M2, and S groups compared to the control group, and the lowest amount was belonging to the severe group. As a result, there was a reverse connection between Kallistatin serum level and the liver injury intensity. Serum kallistatin levels are an essential parameter in determining liver tissue damage levels, and measuring it may help provide a treatment prognosis.
