Subject of study. Dairy products are complex in chemical composition and have a complex of various properties that affect the quality of the fnished product, in particular, its structure. Consumer demands for food quality are constantly growing, which leads to the improvement of technological processes. Therefore, the study of the inﬂuence of technological factors in the production of dairy products for dessert purposes on the formation of their structure is an urgent issue. The study aimed to investigate the inﬂuence of technological factors, in particular, different temperature regimes of packaging on the structure of the fnished product. The results. The article presents the results of studies on the formation of the structure of pudding and cream packaged at different temperatures. It has been shown that the ﬂow curves of dairy desserts, characteristic of thixotropic systems, change their structure under the inﬂuence of mechanical loads. It was found that samples of dairy desserts packaged immediately after thermomechanical processing had a lower thixotropy coefcient compared to samples packaged after cooling. It was found that the viscosity of the retentate-based milk dessert was 10-20 % lower than that of a similar product based on butter. In addition, the viscosity values for retentate-based pudding were 20- 30 % higher than for cream. Conclusions. It has been proved that the temperature of the packaging of dairy desserts, as one of the decisive technological factors, has an impact on the formation of the structure, and, as a result, on the quality of the fnished product. For example, to produce dairy desserts with a consistency typical of pudding or cream, it is necessary to pack at a temperature of at least 65°C. At the same time, the viscosity and ultimate shear stress for cream should be in the range of 55...75 Pa-s and 70...100 Pa, respectively, for pudding - 117...124 Pa-s and 90...110 Pa, respectively.
Key words: dairy desserts, creams, puddings, combined composition of raw materials, temperature conditions, packaging, structure, rheological indicators, quality.

Published: July 2024

Heliciculture is a branch of animal husbandry that deals with cultivation and using edible terrestrial snails for food and cosmetic purposes. This type of animal husbandry has an advantage over others in terms of simplicity of technology, as snails do not require complex technical equipment and care. In addition, they are unpretentious in feeding and resistant to diseases. Heliceculture has signifcant potential for development in Ukraine, as there is already considerable demand for snails in the food and cosmetics market. This industry is also developing rapidly and becoming increasingly popular among farmers and businessmen worldwide. At the same time, achieving success in snail farming requires specifc knowledge and skills. For example, it is essential to choose a suitable cultivation method, ensure optimal keeping and feeding conditions, and adhere to the standards of product storage and processing. It is also worth considering the specifcs of the legislation regulating the breeding and circulation of snails and the possible risks associated with pollution and animal diseases. An essential aspect of the development of helicopter culture is research and development to improve the quality and quantity of products, as well as the technology for reproduction and keeping snails. Such research should help improve efciency and make the industry more competitive. Exploring opportunities to improve the efciency of nutrient use in snail feed can signifcantly increase the proftability of production. Enzyme preparations are widely used in heliceculture to enhance the digestion of complex compounds, reduce the negative impact of anti-nutrients, and improve feed conversion. The use of such products in heliculture is reasonable and can have a positive impact on production efciency. The direction of complex feeding in heliceculture has not been studied much, and the inﬂuence of this cellulolytic drug on the productive qualities of Helix Aspersa Maxima species snails has yet to be clarifed. The results obtained during the study can substantiate the positive aspects of using special preparations to increase snail cultivation efciency and the use of nutrients in the diet. The study was conducted to investigate the effect of cellulosolytic enzyme preparation «AGROCELL» on the productivity of snails of the species Helix Aspersa Maxima. The results of the work showed that the addition of the enzyme preparation «AGROCELL» to the diet increases the absolute increase in live weight of snails by 1.2 g and the chain weight by 0.1-1.1 g.

Published: July 2024

Nonalcoholic fatty liver disease (NAFLD) encompasses a spectrum of conditions ranging from simple steatosis to steatohepatitis, advanced fibrosis and end stage liver disease. Despite the high prevalence and severity of hepatic illness, NAFLD remains underdiagnosed, because of few symptoms, lack of accurate laboratory markers. The study was aimed at to evaluate a bio-chemical score for diagnosing non-alcoholic steatohepatitis. A hospital based cross-sectional observational study was carried out for a period of two years from July 2013 to June 2015 in the Department of Hepatology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh.  The study was conducted among 50 patients of NAFLD attending at department of Hepatology and underwent for biochemical investigations and liver biopsy with NAFLD Activity Score (NAS). All data were presented as mean ± SD and analyzed by SPSS (version 16). Qualitative data were analyzed by Chi-square test and quantitative data were analyzed by student’s t-test. Performance of the test were assessed by sensitivity and specificity test. Statistically significant result were considered when p value < 0.05. Total patients were divided into two groups 25 were NASH and 25 were non- NASH. Mean GGT was found 73.6±48.6 U/L in NASH group and 49.9±25.4 U/L in non-NASH group. There was significant difference in the NAFLD activity score for diagnosing NASH between elevated and normal GGT (P value 0.035). Higher GGT values correlated with higher specificity. The Gamma-lutamyltransferase (GGT) has been proposed as a noninvasive and available marker for assessment of NASH.

Hepatic encephalopathy is a broad spectrum neuropsychiatric abnormalities of liver dysfunction. Ammonia level may correlate with the severity of liver failure. The brain is very sensitive to the toxic effects of ammonia. As a result patient may manifests with irritability, slurring of speech, reversal of sleep-awake cycle, flapping tremor, confusion, stupor or even deep coma. This study was aimed to validate the ammonia level in children with liver failure for the assessment of its severity considering hepatic encephalopathy. This cross-sectional comparative study was conducted among 64 children aged 1-15 years of both sexes (study subjects) diagnosed as acute or acute on chronic liver failure in the Department of Pediatric Gastroenterology and Nutrition, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh during the period of November 2017 to September 2019. The subject were divided into two groups for the comparison of ammonia level to assess the severity in contrast to hepatic encephalopathy. In the first group 32 were liver failure with encephalopathy and in the second group 32 were liver failure without encephalopathy.
Hepatic encephalopathy was diagnosed on the basis of West Haven Criteria. The analysis was done by the Receiver Operating Characteristic Curve with SPSS-20. Among the 64 patients female were 45% whereas male patients were 55%, male female ratio was 1.2: 1. Regarding etiology, Wilson disease was the most common cause and it was nearly two-third (65.6%) of children, cryptogenic cirrhosis was 10%, Hepatitis A was 9.4%, Autoimmune Hepatitis (AIH) was 3.10%, Hepatitis E, Hepatitis B, Hepatitis C, biliary atresia and lipid storage were 1.60% respectively. This study showed that, ammonia of ≥71 µmol/L is an indicator for presence of hepatic encephalopathy in children. The analysis by the Receiver Operating Characteristic Curve showed area under the curve (AUC) is 0.86 with upper bound 0.96 and lower bound is 0.77.  It was observed that about half (48.4%) of the children had positive blood ammonia level (≥71.0 umol/L) and among the children of positive blood ammonia level most of them (80.65%) had hepatic encephalopathy and 19.35% had no encephalopathy. More than half (51.6%) children had negative (<71.0 umol/L) blood ammonia level, among them 21.21% children had encephalopathy and 78.79% patients had no encephalopathy. Sensitivity of blood ammonia was found 78.1%, specificity 81.2%, positive predictive value 80.6%, negative predictive value 78.8% and accuracy 79.7%. In conclusion, high level of ammonia is found with higher grade of encephalopathy and hyperammonia is also found in liver failure without encephalopathy.

Published: July 2024

Introduction: Rheumatoid arthritis (RA) is perhaps the most common inflammatory arthritis, affecting 0.5% to 1% of the general population worldwide. Environmental and genetic influences are important risk factors for pathogenesis of RA. First-degree relatives (FDRs) of RA patients sharing genetic and environmental risk factors for RA may represent as pre-RA state. Since anti-CCP antibody appears years before the onset of RA, it can be used to estimate risk-potential for future development of RA in unaffected FDRs of RA patient. Objective: To see the serum anti-CCP antibody in unaffected FDRs of RA patients. Materials and Methods: This cross-sectional study was conducted from July 2019 to June 2020 in Department of Biochemistry, Dhaka Medical College, Dhaka. A total number of 50 subjects were selected among which 25 were unaffected FDRs of RA patients and the other 25 were age & gender matched healthy subjects. The related RA patients were selected from Rheumatology outdoor, Department of Rheumatology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka and the healthy subjects were taken from the attendants came to the same institute who did not have RA patient in their family. The key variables (age and gender) were recorded and outcome variable (anti-CCP antibody in study subjects) was estimated. Statistical analysis was done by SPSS 26.0 and the significance was defined as p < 0.05. Results: Mean age of the FDRs of RA patient was 31.36 ± 10.51 years and that of healthy subjects was 31.56 ± 8.89 years. Most of the participants were in age group 20-29 years followed by 30-39 years. 4% of FDRs of RA patient were anti-CCP antibody positive and no positive case was recorded in healthy subjects. The median level of anti-CCP antibody in FDRs of RA patient was 0.50 U/mL and that in healthy subjects was 0.09 U/mL. The level of significance (p = 0.002) showed that serum anti-CCP antibody level was significantly higher (within normal range) in FDRs of RA patient than in healthy subjects, which was even more significant in FDRs of seropositive RA patients. Conclusion: This study revealed that serum anti-CCP antibody level was significantly higher (within normal range) in FDRs of RA patient than in healthy subjects and the proportion of positive anti-CCP antibody was more in FDRs of RA patient than in healthy subjects.

Introduction with Objective: The aim of the present study was to assess the role of laparoscopy in evaluation of various Blunt abdominal trauma (BTA) in tertiary care teaching hospital. Materials and Methods: A prospective observational study was conducted from 21st June 2016 to 21st December 2017 among 50 abdominal blunt trauma patients attending at Casualty Block, Dhaka Medical College Hospital, Dhaka, after obtaining requisite consent from the patients attendant. Data were collected through the assessment and investigation report of abdominal blunt
trauma patients in the Casualty Department. The collected data were entered into the computer and analyzed by using SPSS (version 20.1) to assess the role of laparoscopy in evaluation of various blunt abdominal trauma. Results: Most of the patients were from 21-30 years (36%) of age group followed by 11-20 years (32%). The median age of this study population is 27 years. Of the study population, 84% (n=42) were male and 16% (n=8) were female. Male-female ratio was 84:16. In this study, 62% (n=31) of patients underwent only laparoscopy and 38% of patients (n=19%) underwent laparoscopy followed by laparotomy. Perforation of gas containing hollow viscus (94.73%) is responsible for conversion of laparoscopy into laparotomy in patients with blunt abdominal trauma. Among 50 patients 14 patients (28%) developed post operative complications. Rate of wound infection was higher laparoscopy followed by laparotomy (n=11). One patient developed post operative collection following laparoscopy. The accuracy rate is 100% in laparoscopic evaluation of BTA in this study. Conclusion: laparoscopy is a useful modality for evaluating and managing hemodynamically stable blunt abdominal trauma patients.

Authors: Haque Monira , Akhter Rubi , Faisal Md
Published: July 2024

Introduction: Close proximity of urinary tract and genital systems in females poses potential risk of fistulas formation during surgical interventions. Gynaecological malignancy, bleeding, prolonged surgery, the presence of active infection during operation, endometriosis, large uterus, previous pelvic operation, pelvic adhesions and myoma uteri are major predisposing factors that may increase the risk of urological injuries & genitourinary fistulas. Genitourinary fistulas result in continuous or intermittent urinary incontinence and a significant public health issue with negative physical, emotional and social impacts on individuals. Materials and Methods: This cross sectional observational study was conducted in Department of Obstetrics &Gynaecology, Bangabandhu Sheikh Mujib Medical University, Dhaka, from 27th March 2017 to 26th September 2017. The sample was collected by purposive sampling technique. The study subjects were women with iatrogenic fistula (diagnosed after a clinical examination and investigations) attended in out-patients or in-patients department. Result: Mean age of patients was 32.5 ± 9.54 years. Vesicovaginal fistula was commonest cause for iatrogenic genitourinary fistula, present in 34 patients. Ureterovaginal fistula was 10 patients and 6 patients detected urethrovaginal. Aetiological factors revealed that, 46.0% occurred during vaginal hysterectomy, 18.0% due to abdominal hysterectomy, 20.0% due to laparotomy with salphingoophorectmy and 16.0% during laparotomy with cystectomy. Conclusion: The commonest urogenital fistula is the vesicovaginal fistula. Urinary leakage following gynaecological surgery is a dreaded complication due to the formation of urogenital fistula. Thorough evaluation, using all diagnostic tools for complete diagnosis, understanding the pathophysiology and choosing the best surgical procedure are mandatory to obtain good outcomes after the surgical procedures.

Published: July 2024

This study analyzed the lyrics and music video of "Jentaka" by For Revenge using the semiotic approaches of Charles Sanders Peirce and Ferdinand de Saussure. This research used a qualitative approach with semiotic analysis methods. This approach was chosen because the research aimed to explore the meanings contained in the lyrics and music video of “Jentaka” by the band For Revenge. Through a qualitative approach, the researcher could understand and interpret the symbols and signs used in these media. The song depicted themes such as emotional suffering, identity duality, and self-introspection. The lyrics reflected the conflict between the external appearance of being an entertainer and the inner feelings of pain and sadness. Additionally, the inclusion of a Quranic verse from Surah Al-Ankabut, verse 64. The results of the study indicated that semiotic analysis could reveal complex layers of meaning in artistic works, offering a deeper understanding of the messages and themes conveyed by the artist. This research contributed to further comprehension of the use of signs and symbols in music and music videos as a medium of artistic communication.

Published: July 2024

This classroom action research seeks to demonstrate how differentiated instruction might promote students' learning autonomy in a writing class setting. This study included 50 English department students from a private institution in Malang. According to the findings of the preliminary study, students were unmotivated to participate in writing activities because they thought they were boring and uninteresting. They were detected paying little attention to the assigned writing assignments and, as a result, demonstrating poor writing performance. To promote student learning autonomy, the researchers implemented with differentiated instructions in several writing exercises. Using two cycles of classroom action research, the researchers seek to solve the instructional challenge using potential learning strategies. After adopting differentiated instruction, the researchers assessed the students' writing scores and compared them to success criteria. The first cycle resulted in 70% of students meeting the success criterion since they were still unfamiliar with the differentiated instructions. In the second round, the pupils successfully met 85% of the criteria. The findings showed that creating differentiated instructions provided pupils with a favorable challenge. It was evident from the behavioral changes of pupils who exhibited greater enthusiasm for following the directions. Furthermore, the students demonstrated the established learning autonomy, which resulted in improved writing performance. These research findings add to the enrichment of the educational component, since future teachers or researchers may focus on a more comprehensive covering of this teaching technique.

Published: July 2024

A defamatory act is any act of speech that disparages the reputation of a person. Defamation is committed by conveying speech in the form of a series of words or sentences by accusing a person of certain actions, which are aimed at honor and good name so that it can result in the person's dignity or dignity being humiliated or degraded. This research aims to examine Amber Heard's statements for defaming Johnny Depp. The data analyzed are Amber Heard's several statements that indicates false and defamatory (primary data) and also her testimony during the trial as supporting data (secondary data). The primary data was collected and observed through the articles op-ed which written by Amber Heard in Washington Post and the secondary data was collected through the trial transcript. This study uses a qualitative research method that describes data to determine the elements that can defame a person based on forensic linguistic studies. By using this study, the data that has been selected was analyzed using lexical semantics, pragmatics (speech acts), and linked to legislation based on Virginia Law. The researchers found three statements that proved to be defamatory and acted with obvious malice that have damaged Johnny Depp's reputation. The findings of this study have significant implications, showing that defamatory statements can have a profound and lasting impact on an individual's reputation and public perception, emphasizing the importance of the law in protecting and addressing such acts.
Twenty - day Border Conflict in the No Man's Land
Authors: Aksoy M. Talha
Published: July 2024

Due to the civil war in Syria, many Syrians have fled conflict areas in search of safety in other countries, resulting in a severe migratory problem. The situation in Syria grew increasingly complicated post-civil war due to the involvement of global powers and radical Islamist factions. In a significant incident, forces of the Assad regime launched an attack on Turkish soldiers in Idlib, resulting in the death of nine Turkish military personnel on February 27, 2020. The following day, Turkey announced its decision to open its borders to refugees heading to Europe, reversing its previous policy of border closure since 2016. This move is interpreted as Turkey's strategy to increase pressure on NATO and the European Union regarding the situation in Iblid and the demand for a no-fly zone. This paper focuses on analyzing the repercussions of the EU-Turkey Joint Action Plan and its implementation, the escalation of tensions leading to the opening of the Turkish border, and the potential use of Syrian refugees as pawns in a political standoff.

Unfortunately, the anonymity and ubiquity of the internet have further made it easier than ever for misogynistic content and attitudes to spread, which can come with severe developmental consequences for perceptions and behaviors in constructs associated with adolescents.
Talcott Parsons as Psychoanalytically Oriented Social Psychologist
Authors: Treviño A. Javier
Published: July 2024

The mid-twentieth-century Harvard sociologist Talcott Parsons is seldom, if ever, depicted as a social psychologist. Yet, toward the end of his career, he declared that he had done a good deal of work in that field, particularly in regard to the study of mass phenomena. In this article I examine Parsons’s social psychology of mass phenomena and demonstrate that it was greatly influenced by Freudian conceptualizations. I first consider Parsons’s comments on what he saw as the place of social psychology in sociological theory. Next, I discuss several terms that were crucial to his social psychology. I then probe two of Parsons’s articles that provide conceptual context to his writings on deviant collective behavior. Following that, I closely examine Parsons’s studies where he analyzed the mass phenomena of Nazism and antisemitism. Finally, I conclude that between 1940 and 1947 Parsons produced a comprehensive psychoanalytic social psychology.
Keep calm and carry on blending: Experimental insights into Romanian lexical blending
Authors: Vasileanu Monica , Niculescu-Gorpin Anabella-Gloria , Radu-Bejenaru Cristina-Andreea
Published: July 2024

Although lexical blending is considered a creative and unpredictable process, the literature shows that it tends to follow certain patterns ( Gries 2012 ; Beliaeva 2019 ), a tendency observed mainly in English. To check whether such generalisations and constraints are the same for Romanian or whether there are language-specific features affecting lexical blending, we created a hybrid-object image-based online experiment asking 110 Romanian native speakers, students at the University of Bucharest who rated themselves as advanced and intermediate users of English, to use only one word to name the hybrids presented to them; as compounding is mainly used in Romanian to name hybrids, we expected it to be more often used. Surprisingly, 68.31% of the elicited Romanian words were lexical blends, likely due to the linguistic profile of our subjects, reinforcing Vasileanu & Niculescu-Gorpin’s (2022) corpus based-analysis that suggests that, due to the global English influence, the process is also active in Romanian. Most of the elicited Romanian lexical blends observe the patterns acknowledged in the literature, e.g. merging the beginning of the first source-word with the end of the second, preserving the phonological contour of a source-word, and source-word clipping at syllable boundaries. Nevertheless, a handful of items revealed morpho-phonological properties that had been previously considered impossible in blends (e.g. interfixes or switch points inside complex syllable constituents), evidence that some constraints, formulated mainly for English, need to be checked against larger datasets and against other languages as lexical blending is a very creative process that seems to transgress possible constraints.

Authors: Karagöz Şerife
Published: July 2024

Araştırmanın amacı, kişi-örgüt uyumunun prososyal ses çıkarma davranışına etkisinde etik liderliğin rolünü tespit etmektir. Araştırma, Antalya ilinde faaliyet gösteren kamu ve özel sektör çalışanları ile gerçekleştirilmiştir. Araştırma verilerinin analizinde, istatistik paket programlarından (SPSS 22 ve AMOS 24) yararlanılmıştır. Ölçme araçlarının yapısal geçerliliği doğrulayıcı faktör analizi ile test edilmiştir. Ölçeklerin güvenirliği iç tutarlılık katsayıları hesaplanarak değerlendirilmiştir. Araştırma verilerinin analizinde tanımlayıcı istatistikler ile korelasyon ve yapısal eşitlik modeli analizleri kullanılmıştır. Araştırma sürecinde, verilerin toplanması için anket yöntemi kullanılmış olup, örnekleme yöntemi olarak kolayda örnekleme tercih edilmiştir. Araştırma sonucunda, kişi-örgüt uyumunun etik liderlik ve prososyal ses çıkarma davranışı sergileme düzeylerini pozitif yönde ve anlamlı olarak etkilediği tespit edilmiştir. Bununla birlikte etik liderlik prososyal ses çıkarma davranışını pozitif yönde ve anlamlı olarak etkilediği belirlenmiştir. Aynı zamanda kişi-örgüt uyumunun prososyal ses çıkarma davranışı üzerindeki etkisinde etik liderliğin düzeyinde aracılık rolüne sahip olduğu görülmüştür. Bu çalışma, yazında daha önceden ele alınmamış olan bu üç değişkenin bir araya getirildiği araştırma modeli ile önemli bir katkı sağlayabilir. Ayrıca Türkçe yazında genellikle “çalışan sesliliği” ve “ses çıkarma davranışı” gibi kavramlar üzerine odaklanılmakta fakat bu çalışmada “prososyal ses çıkarma davranışı” kavramının öne çıkarılmak istenilmesinin bu çalışmanın özgünlüğünü ve önemini oluşturacağı düşünülmektedir.

Introduction

Hand gestures are an effective communication tool that may convey a wealth of information in a variety of sectors, including medical and education. E-learning has grown significantly in the last several years and is now an essential resource for many businesses. Still, there has not been much research conducted on the use of hand gestures in e-learning. Similar to this, gestures are frequently used by medical professionals to help with diagnosis and treatment.

Method

We aim to improve the way instructors, students, and medical professionals receive information by introducing a dynamic method for hand gesture monitoring and recognition. Six modules make up our approach: video-to-frame conversion, preprocessing for quality enhancement, hand skeleton mapping with single shot multibox detector (SSMD) tracking, hand detection using background modeling and convolutional neural network (CNN) bounding box technique, feature extraction using point-based and full-hand coverage techniques, and optimization using a population-based incremental learning algorithm. Next, a 1D CNN classifier is used to identify hand motions.

Results

After a lot of trial and error, we were able to obtain a hand tracking accuracy of 83.71% and 85.71% over the Indian Sign Language and WLASL datasets, respectively. Our findings show how well our method works to recognize hand motions.

Discussion

Teachers, students, and medical professionals can all efficiently transmit and comprehend information by utilizing our suggested system. The obtained accuracy rates highlight how our method might improve communication and make information exchange easier in various domains.

Due to their unique properties, human mesenchymal stem/stromal cells (MSCs) possess tremendous potential in regenerative medicine, particularly in cell-based therapies where the multipotency and immunomodulatory characteristics of MSCs can be leveraged to address a variety of disease states. Although MSC-based cell therapeutics have emerged as one of the most promising medical treatments, the clinical translation is hampered by the variability of MSC-based cellular products caused by tissue source-specific differences and the lack of physiological cell culture approaches that closely mimic the human cellular microenvironment. In this study, a model for trilineage differentiation of primary adipose-, bone marrow-, and umbilical cord-derived MSCs into adipocytes, chondrocytes and osteoblasts was established and characterized. Differentiation was performed in spheroid culture, using hypoxic conditions and serum-free and antibiotics-free medium. This platform was characterized for spheroid diameter and trilineage differentiation capacity reflecting functionality of differentiated cells, as indicated by lineage-specific extracellular matrix (ECM) accumulation and expression of distinct secreted markers. The presented model shows spheroid growth during the course of differentiation and successfully supports trilineage differentiation for MSCs from almost all tissue sources except for osteogenesis of umbilical cord-derived MSCs. These findings indicate that this platform provides a suitable and favorable environment for trilineage differentiation of MSCs from various tissue sources. Therefore, it poses a promising model to generate highly relevant biological data urgently required for clinical translation and therefore might be used in the future to generate in vitro microtissues, building blocks for tissue engineering or as disease models.
Auditory-motor adaptation: induction of a lateral shift in sound localization after biased immersive virtual reality training
Authors: Guilbert Alma , Bara Tristan-Gael , Bouchara Tifanie
Published: July 2024

Introduction

Sensorimotor adaptation has often been studied in the visual modality through the Prism Adaptation (PA) paradigm. In this paradigm, a lateral shift in visual pointing was found after wearing prismatic goggles. An effect of PA has sometimes been observed on hearing, in favor of a cross-modality recalibration. However, no study has ever shown if a biased auditory-motor adaptation could induce this lateral shift, which appears essential to a better understanding of the mechanisms of auditory adaptation. The present study aimed at inducing an auditory prism-like effect.

Methods

Sixty healthy young adults underwent a session of active audio-proprioceptive training in immersive virtual reality based on Head Related Transfer Functions (HRTF). This training consisted of a game in which the hand-held controller emitted sounds either at its actual position in a control group or at 10° or 20° to the right of its actual position in two experimental groups. Sound localization was assessed before and after the training.

Results

The difference between both localization tests was significantly different between the three groups. As expected, the difference was significantly leftward for the group with a 20° deviation compared to the control group. However, this effect is due to a significant rightward deviation in the control group whereas no significant difference between localization tests emerged in the two experimental groups, suggesting that other factors such as fatigue may have cumulated with the training after-effect.

Discussion

More studies are needed to determine which angle of deviation and which number of sessions of this audio-proprioceptive training are required to obtain the best after-effect. Although the coupling of hearing and vision in PA still needs to be studied, adding spatial hearing to PA programs could be a promising way to reinforce after-effects and optimize their benefits.

Purpose

Percutaneous patent foramen ovale (PFO) closure is becoming more and more common for the treatment or prevention of PFO-associated right-to-left shunt (RLS). This study aims to investigate the value of transesophageal echocardiography (TEE) in percutaneous PFO closure, and to explore a new method that can improve intraoperative diagnosis and surgical safety.

Materials and methods

Based on our inclusion and exclusion criteria, we enrolled 73 patients between 16 and 70 years old (average age 43.25 ± 14.87 years) who underwent percutaneous PFO closure at the Department of Cardiac Surgery, Zhongshan Hospital (Xiamen), Fudan University, from January 2022 to December 2023. Out of the 73 enrolled patients, there were 28 males (38.36%) and 45 females (61.64%), 29 migraine patients (39.73%), 14 patients (19.19%) with headache and dizziness, 14 patients (19.18%) with a history of cerebral infarction (CI), and 25 patients (34.25%) with CI, lacunar infarction or ischemic focus on magnetic resonance imaging (MRI). All patients received routine transthoracic echocardiography (TTE) and agitated saline contrast echocardiography (ASCE) before operations. Percutaneous closure of PFO was completed under the guidance of TEE. In 12 patients, the method of “injection of heparinized sterile saline through the delivery sheath” was used to observe their RLS, and the anatomical characteristics of the PFO according to the shunt path were monitored and evaluated. This method was also applied to some patients to guide the conveyor to pass through the foramen ovale (FO) channel safely and effectively, thereby improving the success rate of PFO closure.

Results

The application of TEE during the procedure of percutaneous PFO closure, including preoperative evaluation, intraoperative guidance, and postoperative reevaluation, can offer further details about the anatomical and shunt characteristics of PFO, improve the diagnosis rate, and confirm the safety of the surgical path. It ensures the safety and reliability of the whole operation, greatly improving the success rate and reducing postoperative complications.

Conclusions

TEE guidance of percutaneous PFO closure has the advantages of minimal trauma, no radiation and real-time visualization, while injecting heparinized sterile saline through the delivery sheath is safer and more effective in improving the success rate and reducing postoperative complications.
Braiding frameworks for collaborative stewardship scholarship
Authors: Carney Molly
Published: July 2024

Human-environment relationships are most frequently viewed from evolutionary perspectives, despite the vast body of literature which highlights how many Indigenous peoples engage with and understand place, plants, and animals as kinship relations. My goals in this essay are twofold: first, to suggest we adopt the phrase stewardship to recognize and uphold notions of respect, reciprocity, and relationships that are common within many Indigenous worldviews, and secondly, to advocate for the use of pluralistic approaches to our collaborative scholarship. I offer examples from my own experiences in reconstructing stewardship histories across people, plants, and places in the Pacific Northwest.

The ability to work with data to extract valuable information is a useful skill set, especially in STEM disciplines that produce large amounts of scientific data. This paper reports on the pedagogy and experience of incorporating fundamental database concepts into a STEM Success course, which included a hands-on project. Students worked in groups to design a database for existing tabular data available on the Web and then derived the data to populate the database using SQL queries. This paper reflects on the experience both from a pedagogical perspective as well as a student perspective, including qualitative code analysis of student feedback and survey results regarding attitudes of confidence using, interest in, and usefulness of databases.
