High differentiation but low divergence: demographic history of grey reef sharks (Carcharhinus amblyrhynchos) across the Indian Ocean
Authors: Dahms Carolin , Momigliano Paolo
Published: July 2023

Marine species can manifest complex patterns of genetic structure due to factors including large geographic distribution ranges and dispersal barriers, sparse long-distance dispersal and high site fidelity. Understanding these connectivity patterns is vital to determine effective management units prioritising vulnerable or evolutionarily distinct populations. Here we investigate genetic differentiation and divergence among grey reef sharks (Carcharhinus amblyrhynchos), comparing western and central Indian Ocean populations on the one side, and eastern Indian Ocean and western Pacific populations on the other. Recent reports of very high differentiation of central and western Indian Ocean from eastern Indian and Pacific populations warranted investigation into whether central and western Indian Ocean populations represent cryptic species of Evolutionary Significant Units (ESUs). Using reduced representation data from 124 previously sequenced individuals, we confirm high differentiation across the Indo-West Pacific (FST ≈ 0.4). Through demographic reconstruction, we show considerably lower effective population sizes and genetic diversity in the western and central Indian Ocean and strong isolation: migration rates to the central-west Indian Ocean are on the scale of 1–4 migrants per 10 generations, which, nevertheless, may still be sufficient to allow adaptive connectivity, i.e. the spread of adaptive alleles between populations maintaining species cohesiveness. Current levels of divergence, however, are well within the range of observed within-species divergence for marine organisms. Although simulations revealed that net divergence between ocean basins is unlikely to reach the levels of the “grey zone of speciation”, these highly differentiated Indian Ocean populations fulfil several requirements of ESUs, and will benefit from targeted management approaches considering their low genetic diversity and the alarming population declines of Carcharhinids.

Purpose: Diabetes mellitus (DM) is the second most common comorbidity in myelodysplastic syndromes (MDS). The purpose of the study was to investigate the clinical characteristics of MDS patients with DM.
Methods: A retrospective analysis was performed on the clinical data of 958 MDS patients with and without DM. Clinical data, including genetic changes, overall survival (OS), leukemia-free survival (LFS) and infection, were analyzed.
Results: Among 958 patients, 202 (21.1%) had DM. TET2and SF3B1 mutations occurred more frequently in the DM group than in the non-DM group (p = 0.0124 and p = 0.0009, respectively). Compared to non-DM patients, MDS patients with DM had poor OS and LFS (p < 0.0001 and p = 0.0003, respectively), especially in the lower-risk group. In multivariate analysis, DM independently predicted OS (HR 1.369 CI 1.078-1.738, p = 0.010). Meanwhile, DM was an independent risk factor for bacterial infection (HR 2.055 CI 1.415-2.984, p = 0.000) and fungal infection (HR 2.146 CI 1.422-3.238, p = 0.000) in MDS.
Conclusions: MDS patients with DM have an inferior prognosis and higher infection incidence, with TET2 and SF3B1 mutations being more frequent in those cases.

Background
Cholangiocarcinoma (CCA) is a group of malignant heterogeneous cancers arising from the biliary tree characterized by insidious onset, poor prognosis and high recurrence rate. Immortalized cancer cell lines are the best and easiest models for in vitro and in vivo cancer research.
Methods
CBC3T-1 was originated from a patient with hilar CCA from China and identified by STR and chromosome karyotype analysis. The malignant phenotype was characterized by wound healing assay, transwell migration, Matrigel invasion assay, clone formation assay and in vivo xenograft mouse models. Screening of sensitive clinical anticancer drugs by CCK-8 assay. The cell line was characterized at the genetic level using transcriptome sequencing and whole exome sequencing.
Results
CBC3T-1 was cultured for over 60 passages. Thorough analysis showed that CBC3T-1 cells share characteristics similar to original tumor cells from patients with cholangiocarcinoma and display a stable phenotype, including features of epithelial origin, stem cell-like properties as well as a high invasive and migratory capability and tumorigenicity in mice. Furthermore, this cell line showed the best sensitivity to paclitaxel, followed by gemcitabine. Sequencing results show that cancer-associated pathways and somatic mutations play a dominant role in the development of CCA.
Conclusions
We established and characterized a novel highly aggressive hilar CCA cell line, CBC3T-1, which provides a new model for studying the progression of hilar CCA as well as developing new therapeutic approaches, enriching the heterogeneous in vitro models of CCA.
Comparative Evaluation Of Amount Of Apically Extruded Debris In Endodontic Retreatment Procedures Using Four Different File Systems- An Invitro Study
Authors: Saxena Tarun
Published: July 2023

Objective(s): To compare the amount of apical debris extruded during endodontic retreatment procedures performed using H files, R-Endo Retreatment files, GPR files and ProTaper Universal Retreatment files.

Materials and Methods: The conventional coronal access cavity was prepared for 40 extracted Mandibular Premolars. The root canals were prepared with ProTaper Next Rotary files till X1.  Obturation was done by combination of Lateral and Vertical Compaction technique. All the samples were later attached to Eppendorf tubes. The samples were then divided into four groups each containing 10 samples on the basis of different retreatment files to be used.  After complete removal of root canal filling material, the debris and the root filling material remnants adhered was collected in preattached Eppendorf tubes. For final weight computation and comparison, the weight of empty tube was deducted from the weight of tube accommodating the debris. ANOVA and Tukey test were applied for statistical analysis.

Results: The R-Endo retreatment files showed minimum apical extrusion of debris than all the other examined files in the study. The apical extrusion of debris for R Endo min to max was -0.045 to 0.009. However, there was no statistically significant difference in amount of apical extrusion of debris by different files system (p>0.005).

Conclusion(s): There was no significant difference between the groups in apical extrusion of debris. Also rotary retreatment files showed lesser apical of debris than Hedstrom hand files. R Endo extruded less debris apically in this study.

Keywords: Apical extrusion of debris; Gutta-percha; Retreatment files.
The Ruminant Farm Systems Model: A decision-support tool for whole farm efficiency and sustainability
Authors: Reed Kristan F.
Published: July 2023

Sustainable dairy production requires methods to quantify the environmental footprint of dairy farms that can inform management decisions. Impact inventories can provide some insight for policy, but are not suitable to inform decisions at the farm level. Decision-support tools like the Ruminant Farm Systems (RuFaS) model represent farm management and esti-mate environmental impacts with enough detail and flexibility to compare the effect of management practices and guide farm management decisions. For example, RuFaS can be used to compare the environment impacts of reproduction protocols. The RuFaS model estimates that improving the reproductive performance of a 1,000-cow herd from a low performance to a baseline performance scenario reduces manure and enteric methane production and the emissions intensity of milk pro-duction for that herd. The expected annual enteric emissions reduction alone is equivalent to removing over 70 gas powered cars from the road for one year.
Liver biopsy procedure and indications
Authors: Tessman Ronald K.
Published: July 2023

Liver biopsy sampling and subsequent analysis for mineral content can be a valuable diagnostic tool for micronutrient associated illness in cattle. Although there may be some ap­prehension when using the blind technique, the procedure has little risk of adverse consequences. Utilizing proper biopsy site preparation and appropriate landmarks reduces risk of compli­cations while optimizing the probability of obtaining a sample large enough for micronutrient evaluation. Liver samples are appropriate for evaluating toxicity associated with cobalt, cop­per, manganese, selenium and zinc and deficiency associated with copper, manganese, selenium and zinc.
Small ruminant dairy production for the bovine practitioner
Authors: Mongini Andrea
Published: July 2023

Goat and sheep dairies are a growing subset of the dairy indus­try in the United States. Although sheep and goats differ signifi­cantly from cattle in some ways, bovine practitioners have a wealth of expertise that can and does greatly benefit the small ruminant dairy industry. The need for greater utilization of knowledge exists and can have a large impact on profitability and sustainability of small ruminant dairies. In this talk, we will review the areas of goat and sheep dairies where bovine veterinarians can have the most influence and how the small ruminants differ from cows in a dairy setting.
Respiratory disease of small ruminants
Authors: MacKay Evelyn
Published: July 2023

Although respiratory disease of small ruminants manifests and responds similarly to respiratory disease of cattle, there is much less research and resources aimed at diagnosis and treatment. Limited vaccinations, diagnostic tests and approved pharmaceuticals make it a more challenging landscape to navi­gate for the practitioner. Despite this, similar approaches in case workup, treatment selection and monitoring can be uti­lized as with other species. A few diseases unique to small ru­minants should be kept in mind, and proper drug usage should be in the forefront of practitioners’ minds when managing these cases.
Effect of increasing GnRH dose during Double- Ovsynch on fertility of lactating dairy cows
Authors: Stangaferro M. L. , Thomas M. J. , Couto Serrenho R. , Moncada Torres J.
Published: July 2023

The rate of ovulation to the first GnRH treatment of Ovsynch-type protocols is key to achieve excellent fertility. In cows syn­chronized with the Double-Ovsynch protocol (DO), only around half of the cows ovulate to the third GnRH injection (first GnRH of the Breeding-Ovsynch portion of Double-Ovsynch). Increas­ing the dose of GnRH at this time has been proven to improve ovulatory response, reaching up to 67% of ovulation rate. Our objective was to determine whether increasing the dose of the third GnRH of DO could improve the reproductive outcomes at first service.

Published: July 2023

The high number of fraud cases in governments has increasingly become a concern among academics and practitioners. Many approaches can be used to minimize fraud cases. However, the role of education in the influence of personality on fraud in the Indonesian government has not been considered. Thus, this study aims to analyze the influence of morality and Machiavellianism as personality factors leading to fraud. Education was tested as a moderating variable. This quantitative study involved a sample of Pekanbaru City government officials. To collect data, questionnaires were sent directly to the respondents. Through the purposive sampling technique, 251 samples were collected. A structural equation with partial least squares was used to test the hypotheses. The test results show that all the proposed hypotheses are accepted. Morality affects fraud with a p-value < 0.001, less than 0.05. Machiavellianism affects fraud with a p-value < 0.001. Education moderates the relationship between morality and fraud with a p-value of 0.048, less than 0.05. Moreover, education moderates the relationship between Machiavellianism and fraud with a p-value < 0.001, less than 0.05. In conclusion, this study contributes to shaping government officials’ behavior to prevent fraud. Character building and high education standards for officials must be integrated to reduce the risk of abuse in Indonesian government.

Diffuse alveolar hemorrhage (DAH) is a potentially life-threatening pulmonary pathology which results in intra-alveolar hemorrhage secondary to disruption of the alveolar capillary basement membrane. Most commonly, these patients present with hemoptysis, hypoxemia and pulmonary infiltrates. Although rare, sevoflurane, an inhalational anesthetic used as a rapid induction agent for anesthesia may be implicated in the etiology of DAH. We report a case of a 21-year-old otherwise healthy male found to have postoperative diffuse alveolar hemorrhage secondary to sevoflurane inhalation. Thus far, only five documented cases describing sevoflurane induced diffuse alveolar hemorrhage have been described in the literature, with prior cases also showing a clear temporal association between sevoflurane administration and symptom onset. Although uncommon, we must take sevoflurane into consideration as a possible etiology of diffuse alveolar hemorrhage when encountering signs of respiratory distress and hemoptysis in postoperative patients.

Published: July 2023

Introduction. Infantile hemangiomas (IHs) are the most common vascular tumors of infancy whose frequency increases with decreasing gestational age. Although rare, periorbital IHs (PIHs) have a high complication rate, with a substantial risk of impaired vision and aesthetic consequences. Because they are considered high-risk IH, such patients must be treated. In the available literature, there is little information about the treatment o f I Hs in very and extremely preterm newborns and infants. Case report. We present three male infants (one very and two extremely prematurely born) with PIHs involving the upper eyelid. In all three cases, IHs were solitary but with different subtypes according to soft-tissue depth (superficial, combined, deep). No additional congenital anomalies were found in any of these cases. An individualized approach to the management of each patient was applied. All infants were treated with oral administration of propranolol, with careful monitoring for potential side effects of the drug and adjustment of treatment, following their eventual occurrence. The introduction of oral propranolol was carried out in a hospital setting, with a gradual increase of the drug dose until the target dose was reached. Conclusion. In the case of PIH, an ophthalmologist is an inevitable part of the medical team. Very and extremely preterm infants are already under the supervision of an ophthalmologist due to mandatory screening for retinopathy of prematurity; how-ever, if they also have PIHs, monitoring must be particularly detailed and long-lasting.

Objective: Few trials studied the links of food components in different diets with their induced lipidomic changes and related metabolic outcomes. Thus, we investigated specific lipidomic signatures with habitual diets and modified diabetes risk by using a trial and a cohort.

Research Design and Methods: We included 231 Chinese with overweight and prediabetes in a randomized feeding trial with Mediterranean diet, traditional or transitional diet (control diet) from February to September 2019. Plasma lipidomic profiles were measured at baseline, third and sixth month by a high-throughput targeted LC-MS. Associations of the identified lipids with habitual dietary intakes were examined in another lipidomic database of Chinese cohort (n=1,117). The relationships between diet-induced changes of lipidomic species and diabetes risk factors were further investigated through both individual lipids and relevant modules in the trial. 

Results: Out of 364 lipidomic species, 26 altered across groups, including 12 triglyceride (TAG) fractions, nine plasmalogens, four phosphatidylcholines (PCs), and one phosphatidylethanolamine. TAG fractions and PCs were associated with habitual fish intake while plasmalogens were associated with red meat intake in the cohort. Of the diet-related lipidomic metabolites, 10 TAG fractions and PC (16:0/22:6) were associated with improved Matsuda index (β = 0.12 to 0.42; PFDR < 0.030). Two plasmalogens were associated with deteriorated fasting glucose (β=0.29 to 0.31; PFDR < 0.014). Similar results were observed for TAG and plasmalogen related modules.

Conclusions: These fish and red meat related lipidomic signatures sensitively reflected different diets and modified type 2 diabetes risk factors, critical for optimizing dietary patterns.

Career planning is an effort someone makes to determine the career path to be achieved after completing the educational process. Only the reality on the ground shows that students' career planning abilities are still relatively low. This is evidenced by the many students still confused about where to go after high school education. This research aims to develop and test a spinning tool as an information service to improve student career planning. This research belongs to the type of development research, which was developed using the Brog and Gall model through the stages of potential and problem analysis, data collection, media planning, design validation, design reviews, media tests, and product versions. The subjects involved in this study were two counselors and 35 ninth-grade high school students. Data were collected using the questionnaire method, with research instruments like product validity sheets and career planning ability questionnaires. The data obtained were then analyzed using quantitative descriptive analysis techniques. The results show that the value of t count ≥ t table is 31.57 > 1.691, which means that Ho is rejected and Ha is accepted. Based on these results, it can be concluded that spinning media as an information service is effectively used in the guidance process because it can improve student career planning.

Authors: Toripa Glenis Veronica , Huwae Arthur
Published: July 2023

Students who work carry out multiple roles in their daily lives, on the one hand working and, on the other hand, having to carry out responsibilities in the lecture process. This dual role is difficult because it provides many challenges and requires good psychological resilience. Therefore, this study aims to determine the relationship between resilience and academic procrastination in students who study while working. This research belongs to the quantitative research with the Karl Pearson correlation design. The subjects involved in this study were 205 working students aged 17-25 and were selected using a non-probability snowball sampling technique. Data collection in the study was carried out using a psychological scale as a questionnaire, which will be distributed online via Google Forms. The data obtained in the study were then analyzed using the product moment correlational analysis technique from Karl Pearson to determine the relationship between resilience and academic procrastination. The data analysis process was carried out with the help of the IBM SPSS Statistics 21 for Windows program. The results of the data analysis show that the correlation coefficient is -0.021 with sig. = 0.382 (p>0.05), meaning there is no significant negative relationship between resilience and academic procrastination in students who study while working.

Dünya özellikle son yüzyılda iklim değişikliği, küresel ısınma ve hava kirliliği gibi üç temel problemle karşı karşıya kalmıştır. Artan insan nüfusu daha fazla kentleşme ve endüstrileşme dolayısıyla hava kirliliğe sebep olmaktadır. Çeşitli sebeplerle doğaya salınan ağır metaller havada bulunan partikül maddelere tutunarak gerek insan gerekse de bitkiler için son derece zararlı olabilmektedirler. Bitki büyüme ve gelişmesi için gerekli olan makro ve mikro besin elementleri içerisinde kalsiyum (Ca), magnezyum (Mg) ve mangan (Mn) aynı zamanda bir ağır metaldir. Bazı ağır metaller düşük miktarları canlı toplulukları için son derece tehlikeli olmakta iken bitki için gerekli olan besin elementleri de belli eşik değerleri aştıkları zaman bitki için toksik bir etki yapmaktadırlar. Bundan dolayı Ca, Mg ve Mn elementlerinin bitki organlarındaki miktarlarının ve bu konsantrasyonlarının yıllar içerisindeki değişiminin tespiti son derece önemlidir. Ankara Ulus semtindeki bir mavi ladin (Picea pungens Engelm.) ağacından alınan dal ve yaprak örneklerinde analizler gerçekleştirilerek, Ca, Mg ve Mn konsantrasyonlarının bitki kısımlarına ve yıllara göre değişimleri incelenmiştir.

Geopark Merangin is one of the World’s Natural Heritages (Geological Heritage Site) in Jambi Province which under the auspices of UNESCO. The area has the potential to be developed into an eco-geotourism area. To support this development, monitoring is needed for geological diversity, biodiversity, and cultural diversity. One potential study that can be explored is the existence of freshwater crabs. To date, the existence of freshwater crab species in the waters of Geopark Merangin has not been reported. This study aims to collect freshwater crabs that can be found in the Geopark Merangin area as a preliminary study of freshwater crab diversity in that area. The result indicates that one of the freshwater crab can be found is Parathelphusa maidroni. The presence of P. maidroni in Geopark Merangin area can serve as bioindicator of good water quality and open up potential for the discovery of other species. Futhermore, the discovery of P. maidroni in the aquatic region of Geopark Merangin can be considered as an initial step towards the identification of various freshwater crab species in that area.  AbstrakKawasan perairan Geopark Merangin Provinsi Jambi merupakan salah satu warisan alam dunia (Geological Heritage Site) dibawah naungan UNESCO.

The use of different energy sources and the worry of running out of some of them in the modern world have made factors such as environmental pollution and even energy sustainability vital. Vital resources for humanity include water, environment, food, and energy. As a result, building strong trust in these resources is crucial because of their interconnected nature. Sustainability in security of energy, water and food, generally decreases costs and improves durability. This study introduces and describes the components of a system named “Desktop Energetic Dark Greenhouse” in the context of the quadruple nexus of water, environment, food, and energy in urban life. This solution can concurrently serve to strengthen the sustainable security of water, environment, food, and energy. For home productivity, a small-scale version of this project was completed. The costs and revenues for this system have been determined after conducting an economic study from the viewpoints of the investor and the average household. The findings indicate that the capital return period is around five years from the investor’s perspective. The capital return on investment for this system is less than 4 years from the standpoint of the households. According to the estimates, this system annually supplies about 20 kg of vegetables or herbs, which means about one third of the annual needs of a family.

The Pieniny Geodynamic Test Field is situated in the middle of the region between the Inner and Outer Carpathians. Geodynamic research conducted in the past in the Pieniny Klippen Belt (PKB) region were suggestive of neotectonic activity. The goal of the investigation was to determine whether the nearby structures, the Podhale Flysh (FP) and the Magura Nappe (MN), are affected by neotectonic activity in the PKB. The goal of the study was to ascertain the velocity and direction of motion of stations situated close to the Pieniny Geodynamic Test Field’s 3 main structures. Twelve GNSS stations, including 6 in the PKB, 3 in the MN, and 3 in the FP, make up the Pieniny Geodynamic Test Field. Three GNSS sites in the Tatra Mountains (TM) complete the entire geodynamic test field. The satellite observations made between 2004 and 2020 (excluding the year 2005 due to lack of observation) were investigated to identify the horizontal movements. Using the IGb14 reference system, the station’s positions and velocities were calculated. First, daily sessions were used to process the horizontal coordinates of the points for an average observation epoch in a given year. Sixteen measurement epochs were included in the long-time solution. Based on the horizontal velocity residues in the north–south and east–west directions, the station’s movement was calculated. The collected results were compared to information from the EUREF Permanent GNSS Network (EUREF) and to the findings of prior research on the tectonic activity of the PKB. The results of horizontal displacements calculated using GNSS measurements in the area of the PKB and nearby structures—the MN and the FP are presented and analyzed in this article.
The Role of Personal Commitment in Association Between Aerospace Education and Service Experience Through Quality Design: A Moderated Mediation Model
Authors: Uyoga Diane , Bonuke Ronald
Published: July 2023

This study investigates whether personal commitment moderates the effect of aerospace education on service experience through quality design. A cross-sectional study using a close-ended questionnaire was administered to a sample of 174 aviation students of Moi University, Kenya. Moderated mediation analyses were conducted using the PROCESS macro in order to investigate the relationship among variables. The results showed that the association between aerospace education and service experience was significant, and this association was mediated by quality design. The mediated effect of quality design was moderated by personal commitment. Based on the findings, companies involved in aviation should focus on improving the good environment of the service encounter (i.e., education, quality design and commitment) to enhance service experience. The findings made a contribution in terms of allowing us to understand the factors that can enhance service experience in the aviation industry.

Published: July 2023

The paper presents the development process of the solid rocket boosters (SRBs) separation system of the ILR-33 AMBER 2K rocket. A redesign of the system was required due to the development of new, larger SRBs. The main system requirements were transmission of forces and moments between the SRBs and the main stage, execution of the separation process at a given moment in flight and mechanical integration simplification. A set of aerodynamics calculations were performed. With the use of computational fluid dynamics software, forces acting on the booster during separation for several angles of attack, as well as the critical booster deflection angle, have been determined. Next, a mathematical model was created to define the load spectrum acting on the system during the flight and separation phases, covering both static and dynamic loads. All the internal and external force sources were considered. A series of motion dynamics simulations were conducted for representative flight cases. Then, the system operational parameters were verified with the use of dedicated ground test facilities. Necessary calibrations of the mathematical model were then implemented, leading to a high level of confidence with the empirical data obtained, thereby leading to a successful system qualification for the flight campaign.
