Remember How Lonely and Awkward You Felt as a New Professional?
Authors: Mori Laura Yturbe , Tshabalala Lerato
Published: December 2024

Being a new professional (NP) in any sector or industry can come with a lot of fear, doubt, and a sense of not belonging. New professionals in the records management and archives professions are not different. The development of any profession is highly dependent on numerous aspects such as a strong intellectual foundation through education, training programs, and professional associations. Focusing on the last aspect, there is a gap that needs to be filled by these communities to welcome, engage, and involve new professionals in the development of records management and archives field (e.g., create/update policies, training, workshops, exposure, etc.). Professional associations play a vital role to provide guidance, development, and networking opportunities for new professionals. According to the results of the survey carried out by the 2021–2022 cohort of the New Professional Program (NPP) of the International Council on Archives (ICA), not all respondents know the benefits of belonging to a professional association or have not had the opportunity to be part of one. Taking into consideration that new professionals are in the initial stage of the career ladder, they begin to learn about their work environment and create their own networks, and they are constantly looking for new opportunities to continue to improve their knowledge and skills and contribute to the profession. Therefore, this article aims to reflect on the 2022 ICA New Professional survey, outline the role of, understand the issue of belonging, and provide suggestions on how professional associations in the records management and archives profession can fill that gap.
2022 Virtual SARBICA Symposium / Symposium virtuel SARBICA 2022 :“The Drowned and the Saved”: Archives during the 1966 Flood in Florence
Authors: Gonnelli Elena , Sergi Lorenzo
Published: December 2024

In 1966 the flood of Florence was one of the most catastrophic events for Italian cultural heritage: the Arno River inundated the city, submerging everything under six meters in height. A great deal of the cultural properties—in our case archives and books—was buried by several cubic meters of torrential water, mud and substances that the river collected on its way. News of this event went around the world, prompting several people to offer their support to help the city and its cultural heritage. Such heroic volunteers are still remembered as the “mud angels.” This article aims not only to provide historical context for reference, but to also analyze the archival procedures that were put in place before, during, and after the disaster, aspects that today constitute an important area for the archives discipline, giving correct directions for the maintenance and administration of archival preservation buildings. For this reason, the example of two case studies (the State Archives of Florence and the Historical Archives of the University of Florence) will allow us to reflect on the preventive interventions adopted or to be adopted, the methods of recovery, and the procedures for the conservation of documentation. Looking at past experience will help build a stronger foundation for the future. Appropriate planning and prevention activities could constitute a new chapter in the relationship between people and the environment. Building on the examples of the past, it is desirable to reflect on the tenuous balance between geographical context and cultural preservation.
Sustainability at the National Archives, UK: Where We Are and Where We Are Heading
Authors: Wilson Helen , Vervoorst Juergen , Johnson Valerie
Published: December 2024

The National Archives, UK, is a working archive with responsibility under the Public Records Act of 1958 to preserve and provide access to digital and analogue records. As a non-ministerial department of the UK Government, allied to the Department for Culture, Media and Sport, we are working to meet or exceed the UK Government’s target of being carbon neutral by 2050. The greatest proportion of our carbon emissions are generated through maintaining current standards of environmental management in our sixteen repositories. Maintaining these conditions as global and local temperatures rise could increase our energy usage. Strategic equipment upgrades and evidence-based changes to our working practices have enabled us to reduce our carbon emissions by eighty percent since 2010. However, more work is still needed to help us achieve carbon neutrality. Following the release of our Sustainability and Climate Action Statement, we have created a sustainability action plan that will guide our activities for the near future. Environmental sustainability intersects with all the other pillars of sustainability. Our current strategy “Archives for Everyone” embraces these, with particular focus on inclusivity, and a need to be entrepreneurial and disruptive to meet the needs of the future. As well as a working archive, The National Archives, UK is the archive sector lead for England. To support archives in their own journeys to increase their sustainability, we are working collaboratively to deliver sustainability-related research, events, training, and resources that are informed by the needs of the sector. *

In this paper, modified Toda (mToda) equation is generalized to form an integrable hierarchy in the framework of Sato theory, which is therefore called mToda hierarchy. Inspired by the fact that Toda hierarchy is 2-component generalization of usual KP hierarchy, mToda hierarchy is constructed from bilinear equations of 2-component first modified KP hierarchy, where we provide the corresponding equivalence with Lax formulations. Then it is demonstrated that there are Miura links between Toda and mToda hierarchies, which means the definition of mToda hierarchy here is reasonable. Finally, Darboux transformations of the Toda and mToda hierarchies are also constructed by using the aforementioned Miura links.

The north–south (NS) anisotropy of galactic cosmic rays (GCRs) is dominated by a diamagnetic drift flow of GCRs in the interplanetary magnetic field (IMF), allowing us to derive key parameters of cosmic-ray propagation, such as the density gradient and diffusion coefficient. We propose a new method to analyze the rigidity spectrum of GCR anisotropy and reveal a solar cycle variation of the NS anisotropy’s spectrum using ground-based muon detectors in Nagoya, Japan, and Hobart, Australia. The physics-based correction method for the atmospheric temperature effect on muons is used to combine the different-site detectors free from local atmospheric effects. NS channel pairs in the multidirectional muon detectors are formed to enhance sensitivity to the NS anisotropy, and in this process, general graph matching in graph theory is introduced to survey optimized pairs. Moreover, Bayesian estimation with the Gaussian process allows us to unfold the rigidity spectrum without supposing any analytical function for the spectral shape. Thanks to these novel approaches, it has been discovered that the rigidity spectrum of the NS anisotropy is dynamically varying with solar activity every year. It is attributed to a rigidity-dependent variation of the radial density gradient of GCRs based on the nature of the diamagnetic drift in the IMF. The diffusion coefficient and mean free path length of GCRs as functions of the rigidity are also derived from the diffusion–convection flow balance. This analysis expands the estimation limit of the mean free path length into the ≤200 GV rigidity region from the <10 GV region achieved by solar energetic particle observations.
Artificial Polytropic Behavior of Plasmas Determined from the Application of Chi-squared Minimization Analysis to Data with Significant Statistical Uncertainty
Authors: Nicolaou Georgios , Livadiotis George , Ioannou Charalambos
Published: December 2024

The effective polytropic index of plasmas is typically determined from the analysis of the plasma temperature (or pressure) and density, which are plasma bulk parameters determined from analyses of in situ plasma observations. Here, we show that the use of the typical chi-squared minimization method in plasma observation analyses results in artificial correlations between the plasma density and temperature, which will introduce errors in the determination of the plasma polytropic relationship. We quantify this potential error by analyzing simulated plasma observations. We specifically show that even in cases of nonvarying plasma, a significant statistical uncertainty in the observations leads to the determination of plasma parameters, which seemingly follow a nearly adiabatic model. Moreover, we consider isobaric plasma variations and discuss the error in the determined polytropic relationship as a function of the actual plasma variations and the statistical uncertainties of the determined parameters. We finally show that the use of an alternative analysis method improves the accuracy of the results.
Levothyroxine therapy in pregnancy: Are we overtreating patients?
Authors: Yanachkova Vesselina , Staynova Radiana , Grekova-Kafalova Daniela , Petkova Valentina
Published: December 2024

Background: Pregnancy imposes unique physiological requirements on the mother’s thyroid gland to meet the thyroid hormone demands both for her and the fetus. A lack of consensus in current guidelines on diagnosing thyroid dysfunction during pregnancy and administering levothyroxine raises concerns regarding treatment efficacy. As hypothyroidism—subclinical or overt—is a recognized risk factor for an unfavorable pregnancy outcome, the administration of excessive or unneeded therapy can also lead to complications.

Objective: This study aims to evaluate the prevalence of levothyroxine replacement therapy among euthyroid pregnant women.

Materials and methods: A retrospective cohort study was conducted using the data from 6237 pregnant women who delivered at the OB/GYN Hospital “Dr. Shterev” in Sofia, Bulgaria, between January 2017 and December 2022. Thyroid function data were available for 1746 pregnant women meeting inclusion criteria: aged > 18 years, with singleton pregnancies, and thyroid hormone level tests conducted no later than mid-second trimester.

Results: According to pregnancy-specific thyroid disorder diagnostic criteria, patients were categorized into euthyroid (n = 1066), subclinical hypothyroidism (n = 421), overt hypothyroidism (n = 48), isolated maternal hypothyroxinemia (n = 160), gestational thyrotoxicosis (n = 46), and Graves’ disease (n = 5). Analysis revealed that 37.7% (n = 401) of euthyroid pregnant women were prescribed levothyroxine. Only 22.9% (n = 92) of euthyroid women received hormone replacement therapy due to autoimmune thyroiditis.

Conclusion: Our findings prompt consideration regarding the appropriateness of levothyroxine therapy for euthyroid pregnant women. Clear guidance is warranted on the initiation of hormone replacement therapy during pregnancy.

Published: December 2024

Material from the Upper Eocene Tavda Formation of Western Siberia contains a new species, Aporrhais sibericasp. nov. It has been misidentified as A. cornuta Korobkov, 1949, an aporrhaid originally described from the Upper Eocene / Lower Oligocene of the Turan Sea. The main difference between A. siberica and A. cornuta is the missing spire-adnate digitation of A. siberica. Publications referencing both morphologies are analyzed, and revised synonymies are presented.

Authors: Gründel Joachim , Nützel Alexander
Published: December 2024

A new collection of Upper Jurassic (Kimmeridgian) gastropods from the reefal limestones of the Saal quarry near Kelheim (Lower Bavaria, Germany) is reported. It has yielded 119 species of which 80 species are nominate species, the others are treated in open nomenclature. This increases the number of known gastropod species from the Saal quarry by 54 (31 nominate species). A total of 178 gastropod species (107 nominate species) have now been reported from this locality making this occurrence the richest one from the Late Jurassic. Despite the fact that previously studied collections are from the same quarry and have the same age, these collections differ considerably from each other in species composition and relative abundances of shared species. This reflects facies differentiation in the quarry as well as colletion biases. One new genus (Kelheimiagen. nov.) and 15 new species are described: Scurriopsis cragolissp. nov., Pseudorhytidopilus ? quadratussp. nov., Rimulopsis danuviensissp. nov., Nododelphinula oblongasp. nov., Creniturbo gibbosussp. nov., Kelheimia triangulatasp. nov., Neritopsis ? rotundatussp. nov., Oonia kimmeridgiensissp. nov., Eustoma ? gracilissp. nov., Cryptoptyxis ? spinosussp. nov., Turritella lucagritasp. nov., Neuburgensia angulatasp. nov., Neuburgensia rarasp. nov., Diarthema asperasp. nov., and Aphanoptyxis sinerugaesp. nov.Leptomaria tuberosa Gründel, Keupp & Lang, 2017 is seen as subjective synonym of Leptomaria goldfussi (Sieberer, 1907). Gymnocerithium ? convexoconcavum Gründel, Keupp & Lang, 2019 is placed in the genus Neuburgensia (comb. nov.). Amphitrochus ? gerberi Gründel, Keupp & Lang, 2017 is placed in the genus Serrettella (comb. nov.). Neritopsis subvaricosa Brösamlen, 1909 is placed in the genus Hayamiella (comb. nov.).

Slache, le rire brusseleir de la radio à la bande dessinée
Authors: Crucifix Benoît , Hermans Sébastien
Published: December 2024

À la fin des années 1930, l’humoriste et dessinateur Marcel Antoine anime les mésaventures de Slache, un personnage-type s’exprimant à l’accent bruxellois, sur les ondes de Radio-Schaerbeek. Joué sur les scènes de théâtre et de cabarets, relayé dans la presse, et adapté sous forme de bandes dessinées dans Spirou, Slache connut un bref mais fulgurant succès populaire. Cet article reconstruit cette trajectoire multi-médiatique de Slache et de son créateur Marcel Antoine afin de saisir les réseaux de circulation entre la radio, les arts de la scène, la presse illustrée, le dessin humoristique et la bande dessinée. L’article s’empare des enjeux de cette circulation transmédiatique entre culture sonore et culture graphique en termes de matérialité, de sérialité et d’auctorialité.
Nonsense as Autobiography: The Children’s Poems and Family Secrets of Laura E. Richards
Authors: Ginzburg Etti Gordon
Published: December 2024

Laura E. Richards’s (1850-1943), the first lady of American nonsense poetry, was among the few nineteenth-century professional women writers who composed literary autobiographies, and the only one who wrote two, one for adult readers and one for children. The present essay argues for reading Laura E. Richards’s nursery and Nonsense rhymes as her third autobiography. Unlike her formal autobiographies, which primarily served to maintain a mythic legacy of her renowned parents, Julia Ward and Samuel Gridley Howe, Richards’s nonsense poetry subtly subverts the constraints of this narrative. Beneath a playful surface, her rhymes reveal insights and tensions that her official autobiographies strategically obscure. By examining Richards’s nonsense verses alongside her autobiographies, personal and historical accounts, and within the broader context of nineteenth-century Nonsense poetry and women’s and children’s literature, this essay argues for a richer, more nuanced understanding of her life and work. In doing so, it repositions Richards and her poetry within the cultural and literary history of her time, offering both the poet and her oeuvre the critical attention they have long been denied.

Published: December 2024

Good Handling Practices (GPH) for fish will have an impact on the quality of fish catches. Therefore the addition of material as a good insulator in the hatch of a fishing vessel is needed. Polyurethane as an insulator material can be used as one of the additional materials in the hatch of a fishing vessel. This study aimed to compare the thermal conductivity properties of the composition and thickness of polyurethane. The results will find out how the influence of composition and thickness of polyurethane affect the insulation of the fishing vessel hatch. The ideal polyurethane insulation should have a material density ρ ≥ 30kg/m3. Density values from testing variations in polyurethane composition show density values in the range of 40kg/m3-100kg/m3, this outcome meets the criteria for a high-quality polyurethane insulating material.

Authors: Alsaati Ahmed Abdulaziz , Alhumaydhan Abdulrahman Sami , Alshammari Tmadher , Albarrati Ayman Mohammed , Alsanad Lamyaa , Albinsaad Loai Saleh
Published: December 2024

Introduction:

Cultural standards of beauty significantly impact individuals’ physical appearance perceptions and plastic surgery considerations. This study aims to investigate how Saudi cultural norms influence women’s attitudes and preferences regarding plastic surgery.

Subjects and Methods:

A cross-sectional survey involved 1602 Saudi women across diverse demographics. A validated questionnaire assessed familiarity with plastic surgery, satisfaction with appearance, societal pressure experiences and preference determinants. Descriptive analyses characterised responses, while tests examined associations between variables.

Results:

The sample comprised mainly younger, educated women familiar with plastic surgery, with 50.1% considering it. Moderate satisfaction levels contrasted societal pressure experiences. Family/friends moderately influenced decisions, conforming to traditions remained important. Higher education correlated with reduced preferences. Employed women also exhibited less inclination. Preferences correlated positively with understanding beauty standards and internal/external validation seeking. Societal acceptance, media exposure and comparisons impacted preferences.

Conclusion:

Saudi cultural norms significantly shaped plastic surgery attitudes and awareness. Preferences varied with demographics and internalisation of beauty ideals. Understanding societal factors’ complex influences on women’s physical appearance perceptions offers insights for sensitive clinical consultations and informed consent. Targeted initiatives may help address unhealthful social pressures driving unnecessary procedures through empowering self-acceptance.

The eighth workshop of the Worldwide Network for Blood and Marrow Transplantation (WBMT) was held in Islamabad, Pakistan, from September 22 to 23, 2022, aiming to foster hematopoietic stem cell transplant (HSCT) activity in the World Health Organization (WHO) Eastern Mediterranean Region (EMRO). Participating countries, including Pakistan, Oman, Iran, and Saudi Arabia, reported increased HSCT in the last few years, whereas others from the EMRO and beyond, including Qatar, United Arab Emirates, Nepal, and Bangladesh, started HSCT recently and have developed HSCT programs with excellent results. During educational sessions and open dialog, participating teams and international experts from the WBMT shared their experience and discussed minimum essential requirements for establishing and expanding HSCT in emerging countries, indications for HSCT training and dissemination of knowledge, stem cell donor selection and safety, quality assurance in transplant centers, and the value and importance of transplant outcome databases. International support, collaboration, and local engagement, including government participation and WHO assistance, are valuable in increasing HSCT access worldwide.
Evaluation of the Effect of Different Contaminants on the Shear Bond Strength of Different Adhesive Systems - An In Vitro Study
Authors: Jha Monalisha , Kumar Amit , Telang Abha , Kumari Puja , Verma Gaurav , Bharti Karuna
Published: December 2024

ABSTRACT

Background:

The bonding of restorative materials to tooth structure is made easier by dental adhesive solutions, which are essential in restorative dentistry. Nonetheless, there are a number of things that can affect how well they operate, such as oral environmental contaminants.

Methodology:

The research utilized a regulated experimental framework, segmenting the samples into smaller groups to symbolize discrete contamination scenarios observed in dentistry settings, such as artificial saliva and Viscostat clear contamination prior to and following bonding agent curing. The adhesive groups consisted of three subgroups: ADPER SINGLE BOND-2, CLEARFIL LINER BOND-F, AND SINGLE BOND UNIVERSAL ADHESIVE. Each subgroup had 11 samples. To assess the variations in shear bond strength across the groups, statistical analysis was applied, most likely using SPSS or a comparable program.

Results:

In all contamination circumstances, ADPER SINGLE BOND-2 consistently showed a stronger shear bond strength than CLEARFIL LINER BOND-F and SINGLE BOND UNIVERSAL ADHESIVE, according to the data. To be more precise, ADPER SINGLE BOND-2 showed better results even when artificial saliva and Viscostat clear were present, suggesting that it might be used in clinical settings. These results highlight how crucial adhesive choice is to get the best bonding results possible in restorative dentistry.

Conclusion:

According to the study, ADPER SINGLE BOND-2 may provide medical professionals with a dependable solution for creating strong, long-lasting adhesive connections, especially in difficult clinical settings where contamination is a possibility.
Comparative Evaluation of Ketoprofen Gel Alone and in Combination with Doxycycline Gel as Local Drug Delivery in the Treatment of Chronic Periodontitis among Smokers and Non-Smokers: A Randomized Clinical Trial
Authors: Gandhi Krupali J. , Nadig Priyadarshini P. , Vishnoi Shivlal , Sheth Bhumika S. , Desai Jinal , Raj Kandarp
Published: December 2024

ABSTRACT

Background and Objective:

Often, the treatment goals for chronic periodontitis in smokers are not achieved only by scaling and root planing (SRP) as non-surgical periodontal therapy. Adjunctive therapy such as local drug delivery (LDD) can be carried out in an attempt to reduce the need for periodontal surgery. The study was carried out to determine the efficacy of subgingivally delivered ketoprofen (K) + doxycycline (D) gel and compare it with that of subgingivally delivered ketoprofen (K) gel alone as an adjunct to SRP in smokers and non-smoker patients having chronic periodontitis.

Materials and Methods:

Twelve patients in the non-smoker group and nine patients in the smoker group having chronic periodontitis with ≥4-mm pocket depth in at least three adjacent teeth in each quadrant were recruited for the study. The quadrants were randomized into K alone and K + D subgroups. 2.5% ketoprofen gel and 2.5% ketoprofen + 3% doxycycline gel were delivered into designated sites after SRP, and the sites were secured using periodontal dressing. Plaque index (PI), bleeding on probing (BOP), probing pocket depth (PPD), and relative attachment level (RAL) were recorded at baseline and 3 months.

Results:

At 3 months follow-up, both the groups showed significant improvement in PI, BOP, PPD, and RAL (P < 0.05). K + D showed a significantly greater reduction of PI, BOP, PPD, and RAL in both smokers and non-smokers than K alone (P < 0.05). Non-smokers responded significantly better than smokers for PI, BOP, PPD, and RAL with both treatment modalities (P < 0.05).

Conclusion:

The results indicate that smokers and non-smokers demonstrate better clinical outcomes by using K + D LDD as an adjunct to SRP. Moreover, non-smokers responded better to both modalities than smokers.

Results:

The immunohistochemical expression of Bcl-2 in oral leukoplakia with different grades of dysplasia, in verrucous carcinoma and in different grades of oral squamous cell carcinoma with normal mucosa were compared. Moreover, the expression of Bcl-2 was found to increase significantly between dysplasia and different grades of oral squamous cell carcinoma.

Conclusion:

The expression of Bcl-2 has always guided the researchers towards mapping the progression of dysplasia as well as malignant transformation at the molecular level.
Assessment of the Periodontal Parameters in Pregnant Women Diagnosed with Metabolic Syndrome: A Cross-Sectional Study
Authors: Sayeed Ghousia , Varghese Sheeja S.
Published: December 2024

ABSTRACT

Background:

The prevalence of metabolic syndrome (MeS) is increasing due to modern lifestyles, making it essential to explore its connection with conditions like periodontitis, particularly in pregnant women. This study aims to evaluate the periodontal parameters health of pregnant women with metabolic syndrome.

Material and Methods:

The study included 144 pregnant women aged 18–34 with MeS. Demographic data collected encompassed age, nutrition, medical history, and oral health practices. Dental exams assessed the gingival index, plaque index, bleeding on probing, probing depth, and clinical attachment loss, classifying participants into mild, moderate, and severe periodontitis. Blood glucose, triglycerides, HDL cholesterol, systolic and diastolic blood pressure, waist circumference, and BMI were measured to analyze the relationship between the number of MeS components and periodontal disease severity using a Chi-square test. A P value of less than 0.05 was considered statistically significant.

Results:

Gingivitis was present in 33.3% of the subjects, whereas severe periodontitis was in 20.8%. Nonetheless, there was no discernible correlation (P > 0.05) between periodontal disease severity and MeS risk variables.

Conclusion:

The majority of subjects had gingivitis, although all patients with MeS exhibited periodontal disease to some degree. However, there is still debate over whether or whether an increased presence of MeS components is associated with more severe periodontal disease, particularly during pregnancy.
Sleep Pattern and the Incidence of Early Childhood Caries: Systematic Review
Authors: Abdul Nishath Sayed
Published: December 2024

ABSTRACT

Background:

The relationship between sleep patterns and early childhood caries (ECC) has been variably explored, with emerging evidence suggesting significant interconnections. This systematic review aimed to synthesize existing research findings on the influence of sleep hygiene on ECC incidence, focusing on how variations in sleep quality and routines impact dental health in children.

Methods:

The review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria to ensure rigor and transparency. A comprehensive literature search was conducted across various databases.

Results:

The collective analysis revealed a consistent linkage between poor sleep quality or irregular sleep patterns and higher ECC incidence. Common findings across the reviewed studies included the negative impact of late sleep onset and the beneficial effects of structured bedtime routines on ECC risk. While all studies agreed on the general influence of sleep quality on dental health, differences were noted in the emphasis on specific sleep disturbances, parental roles, and broader developmental outcomes linked to sleep hygiene.

Conclusion:

Sleep hygiene plays a critical role in the incidence of ECC, with both general sleep patterns and specific nighttime routines contributing to dental health outcomes. The findings suggest that interventions aimed at improving sleep hygiene could be beneficial in ECC prevention.
Dysregulation of genes involved in the long-chain fatty acid transport in pancreatic ductal adenocarcinoma
Authors: Poenaru Radu Cristian , Milanesi Elena , Niculae Andrei Marian , Dobre Anastasia-Maria , Vladut Catalina , Ciocîrlan Mihai , Balaban Daniel Vasile , Herlea Vlad , Dobre Maria , Hinescu Mihail Eugen
Published: December 2024

BACKGROUND

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive lethal malignancy with limited options for treatment and a 5-year survival rate of 11% in the United States. As for other types of tumors, such as colorectal cancer, aberrant de novo lipid synthesis and reprogrammed lipid metabolism have been suggested to be associated with PDAC development and progression.

AIM

To identify the possible involvement of lipid metabolism in PDAC by analyzing in tumoral and non-tumoral tissues the expression level of the most relevant genes involved in the long-chain fatty acid (FA) import into cell.

METHODS

A gene expression analysis of FASN , CD36 , SLC27A1 , SLC27A2 , SLC27A3 , SLC27A4 , SLC27A5 , ACSL1 , and ACSL3 was performed by qRT-PCR in 24 tumoral PDAC tissues and 11 samples from non-tumoral pancreatic tissues obtained via fine needle aspiration or via surgical resection. The genes were considered significantly dysregulated between the groups when the p value was < 0.05 and the fold change (FC) was ≤ 0.5 and ≥ 2.

RESULTS

We found that three FA transporters and two long-chain acyl-CoA synthetases genes were significantly upregulated in the PDAC tissue compared to the non-tumoral tissue: SLC27A2 (FC = 5.66; P = 0.033), SLC27A3 (FC = 2.68; P = 0.040), SLC27A4 (FC = 3.13; P = 0.033), ACSL1 (FC = 4.10; P < 0.001), and ACSL3 (FC = 2.67; P = 0.012). We further investigated any possible association between the levels of the analyzed mRNAs and the specific characteristics of the tumors, including the anatomic location, the lymph node involvement, and the presence of metastasis. A significant difference in the expression of SLC27A3 (FC = 3.28; P = 0.040) was found comparing patients with and without lymph nodes involvement with an overexpression of this transcript in 17 patients presenting tumoral cells in the lymph nodes.

CONCLUSION

Despite the low number of patients analyzed, these preliminary results seem to be promising. Addressing lipid metabolism through a broad strategy could be a beneficial way to treat this malignancy. Future in vitro and in vivo studies on these genes may offer important insights into the mechanisms linking PDAC with the long-chain FA import pathway.

Intake refers to the food and beverages consumed by an individual within a certain period. It encompasses all nutrients absorbed by the body from food and beverages sources. Adequate and balanced intake is necessary to maintain the health and well-being of the body, including sufficient energy, carbohydrates, protein, fat, vitamins, and minerals. Intake analysis helps evaluate the eating patterns of individuals or populations to support optimal nutritional needs fulfillment. This study aims to analyze the energy, carbohydrate, and fiber intake from staple foods in the non-agricultural area of Baubau City in 2022. The research involved 127 respondents residing in coastal or non-agricultural areas of Baubau City. The data collection method used was the Semi-Quantitative Food Frequency Questionnaire (FFQSQ) through direct interviews. The research findings indicate that the energy, carbohydrate, and fiber intake from staple foods in the non-agricultural area of Baubau City ranged from 20-40%, with carbohydrate intake also ranging from 20-40%, while fiber intake ranged from 0-20%. The most frequent average consumption was 3293.38 kcal/day of rice, 31.77 kcal/day of corn, 67.83 kcal/day of sweet potatoes, and 65.70 kcal/day of cassava. The conclusion of this study is that the energy, carbohydrate, and fiber intake from staple foods in the non-agricultural area of Baubau City are still insufficient. The research recommendation is for the community to pay more attention to daily nutritional intake, especially in terms of energy, carbohydrates, and fiber. The government should enhance nutritional education for the community, especially in non-agricultural areas, about the importance of consuming diverse, balanced, and appropriately portioned foods

Published: December 2024

Based on insights from ongoing clinical studies, a significant step forward in the discovery of potential markers in the differential diagnosis of stroke is expected. Considering that the differential diagnosis of stroke can greatly influence clinical practice, the importance of these studies in identifying and validating potential diagnostic markers is high. Developing a marker panel may help distinguish ischemic and hemorrhagic strokes and provide a faster, more accurate diagnosis. However, considering heterogeneous stroke populations and different disease stages, larger samples and standardized assessment methods remain necessary. Future studies may fill knowledge gaps in this field and clarify the role of markers in stroke diagnosis in clinical practice.
Locomotion Control of a Bipedal Wheeled Robot Using Virtual Model Control and Linear Quadratic Regulator Techniques
Authors: Dan-Dan Liu  , Wei Wang
Published: December 2024

This paper aims to develop a balance control technique and investigates its impact on the stability and disturbance rejection capability of a bipedal wheeled robot. The bipedal wheeled robot is equivalent to a wheeled inverted pendulum nonlinear model with a legs-airframe centroid variable rod. The nonlinear model is linearized and decoupled into two subsystems: straight-line control using linear-quadratic regulator (LQR) for balance and speed, and steering control employing proportional integral derivative (PID). Height control adjusts the virtual force with PID-Feedforward, while hip torque is determined by virtual model control (VMC). MATLAB simulation confirms effective control of height, linear motion, and steering, with decoupling enhancing steering performance.
Team Leadership Curriculum Development: A Descriptive Account of Employing Backward Design in a Cross-Cultural Setting
Authors: Lewis Jason E.
Published: December 2024

This article presents a curriculum design aimed at enhancing team leadership skills among the student leaders of a university choir in Central Asia. The unique context revolves around a university without a fine arts program where students establish various student clubs to explore creative interests. The focus is on the university choir, led by a director who struggled initially to align with the students’ preference for contemporary songs over classical repertoire. To address this challenge, a leadership team was formed, but the lack of formal training in leadership hindered their effectiveness. The curriculum design followed a backward design approach, emphasizing desired learning outcomes, including cognitive and affective domains. The design encompassed activities such as academic prompts, reflective exercises, and collaborative planning sessions spread over two sessions. Assessment involved informal checks, academic prompts, and observing behavioral changes post-workshop. The aim was to equip the leaders with practical leadership skills to improve overall team effectiveness.
