Introduction:This study was aimed at comparing the effect of poppy seed consumption and educational approach on how to use Bandura's cognitive-social theory on self-efficacy of elderly pain management with knee osteoarthritis in Babol city; 2022-2023.
Methods: This randomized clinical trial study of three parallel and double-blind groups was conducted on 129 elderly people with osteoarthritis of the knee referred to the Babol city pain clinic. The participants were placed in three groups A, B and C using the 6 block randomization method using Excel software. Group A received oil consumption along with training based on the Bandura model , group B received oil without training, and group C as control group received routine treatments. Demographic, PSEQ (pain self efficacy questioner VAS (visual analogue scale) were used to collect data. Ethical considerations were observed. Data was analyzed using SPSS23 statistical software and compared of the primary characteristics of the group Chi-square test was used for qualitative variables and analysis of variance was used for quantitative variables. (If the data does not follow the normal distribution, the non-parametric equivalent of Kruskal-Wallis was used).
Results: The elderly were mostly female(102 n, 77.9. No significant difference was observed in the visual score of pain between groups A and B before and 4 weeks after the intervention, before and 8 weeks after the intervention and 4 and 8 weeks after the intervention (P<0.05). However, there were significant differences between groups C and B before and 4 weeks after the intervention and before and 8 weeks after the intervention (P<0.05). There is no significant difference between the PSEQ pain management self-efficacy scores 8 weeks after the implementation of the intervention between groups A and B (P = 0.331). But a significant difference was observed between groups A and C (P=0.001).
Conclusion: The results of the present study showed that the consumption of poppy seed oil alone can improve pain and self-efficacy in pain management. Using Bandura's learning theory produces little change in pain and pain management self-efficacy. Also, it is necessary to repeat the training program to improve the training effect.

Diagnostic Significance of Mean Platelet Volume and Erythrocyte Distribution Width in Calves with Sepsis
Authors: Uztimür Murat
Published: November 2024

Medical studies conducted on humans have revealed significant changes in hematological parameters dur-ing sepsis and used these changes for diagnostic and prognostic purposes. However, there are very few studies on the diagnostic and prognostic utility of hematological parameters in the field of veterinary medicine. The objective of this study was to assess whether the parameters mean platelet volume (MPV), erythrocyte distribution width standard devi-ation/coefficient of variation (RDW-SD/CV), platelet distribution width (PDW) and plateletcrit (PCT) hold diagnostic significance in identifying sepsis in calves, while also investigating the interrelationships of these parameters within these sepsis group. The study included 45 calves diagnosed with sepsis and healthy 15 calves as control group. In calves with sepsis, MPV, PCT, RDW-SD, RDW-CV and total leukocyte count were found to be significantly higher than the control group. In their analysis for the diagnosis of sepsis in calves, the sensitivity of MPV was 86.67, the specificity was 84.44, the area under the curve (AUC) was 0.91, and the cut-off point value was 5.95 fL. In addition, the AUC values for other parameters were found as PCT 0.79 (P=0.009), RDW-SD 0.68, RDW-CV 0.75 and WBC 0.80, respec-tively. In the correlation analysis between MPV and other parameters, it was determined that there was a significant relationship between PCT 0.630, PDW 0.310, WBC 0.271, RDW-SD 0.383 and RDW-CV 0.-643. In conclusion, MPV may be a useful biomarker in calves with sepsis due to its favorable diagnostic performance in the early detection of sepsis in new born calves with diarrhea. In order to determine the effects of the results in this study on sepsis very well, it is necessary to work with populations with large sample numbers in the future.
The effect of the feed supplement “Globigen jump start” on the morphometric parameters of the small intestinal mucosa of piglets
Authors: Boniuk N. V. , Shchebentovska O. M.
Published: November 2024

Early weaning of piglets from the sow with a rapid transition from milk to pelleted feed is a common practice in industrial pig farming. To mitigate the feed-related stress in piglets during this period, supplements are introduced into their diet aiming to boost immune response, reduce pathogenic microorganisms in the intestines, and stimulate digestion. This article presents the results of a research on the effect of the feed supplement “Globigen Jump Start”, which contains dried yeast and immunoglobulin-enriched egg powder, on the number of goblet cells and the morphometric parameters of the piglets' small intestine. It was found that the addition of this feed supplement to the piglets' diet significantly increased the height of the duodenal villi by 37.43 % (P > 0.001) by day 14 of the experiment and improved the villus-to-crypt depth ratio, indicating an increase in the surface area and the mucosa's improved ability to absorb nutrients. Additionally, feeding changes also affected the size of the villi in the jejunum and ileum, where a significant increase in size was also observed by day 14, by 12.79 % and 6.6 %, respectively, compared to the control group of piglets. Morphometric studies revealed a trend toward thickening of the muscular layer in both the jejunum and ileum during the first two weeks of consuming pelleted feed with the “Globigen Jump Start” supplement, likely due to changes in diet and the altered feed digestion rate. During the transition to a different type of feed, differences were also noted in the number of goblet cells in the small intestinal mucosa, which produce mucin that protects the body from endogenous and exogenous irritants, microbial adhesion, and aids nutrient transport. In the duodenum of the experimental group of piglets, the number of goblet cells was higher by 3.2 cells on day 14 compared to the control group, and by day 28, this difference decreased to 1.7 cells. A similar trend was observed in the jejunum at both day 14 and day 28, with a significant increase in goblet cell count in the experimental group by 11.6 (P > 0.01) and 13.1 (P > 0.001) compared to control animals. In the ileum of the experimental group, an advantage was also noted. On day 14, the goblet cell count was significantly higher by 6.4 cells (P > 0.05) and by 14.6 (P > 0.001) on day 28 compared to the control group.

Background: Neoadjuvant chemotherapy (NAC) is the standard of care for patients with locally advanced breast cancer (LABC). The study was conducted to investigate the utility of quantitative ultrasound (QUS) carried out during NAC to predict the final tumour response in a multi-institutional setting.

Methods: Fifty-nine patients with LABC were enrolled from three institutions in North America (Sunnybrook Health Sciences Centre (Toronto, Canada), MD Anderson Cancer Centre (Texas, USA), and Princess Margaret Cancer Centre (Toronto, Canada)). QUS data were collected before starting NAC and subsequently at weeks 1 and 4 during chemotherapy. Spectral tumour parametric maps were generated, and textural features determined using grey-level co-occurrence matrices. Patients were divided into two groups based on their pathological outcomes following surgery: responders and non-responders. Machine learning algorithms using Fisher's linear discriminant (FLD), K-nearest neighbour (K-NN), and support vector machine (SVM-RBF) were used to generate response classification models.

Results: Thirty-six patients were classified as responders and twenty-three as non-responders. Among all the models, SVM-RBF had the highest accuracy of 81% at both weeks 1 and week 4 with area under curve (AUC) values of 0.87 each. The inclusion of week 1 and 4 features led to an improvement of the classifier models, with the accuracy and AUC from baseline features only being 76% and 0.68, respectively.

Conclusion: QUS data obtained during NAC reflect the ongoing treatment-related changes during chemotherapy and can lead to better classifier performances in predicting the ultimate pathologic response to treatment compared to baseline features alone.
Laser activatable perfluorocarbon bubbles for imaging and therapy through enhanced absorption from coupled silica coated gold nanoparticles

Published: November 2024

Nanoparticles have extensively been used for cancer therapy and imaging (i.e., theranostics) using various imaging modalities. Due to their physical and chemical properties (e.g., absorption, fluorescence, and magnetic properties) they have been used for image guided therapy for cancer treatment monitoring. There are various limitations that make many theranostic agents unable to be used for the extended periods of time required for enhancing theranostic capabilities. Some of these are due to inherent characteristics (e.g., change and/or breakdown of structure) present upon continuous irradiation and others are due to environmental (i.e., physiological) conditions that can lead to physical instability (i.e., in terms of size) affecting the amount of particles that can accumulate at the target site and the overall contrast that can be achieved. In this study, perfluorohexane (PFH) nanoemulsions (NEs) were synthesized with silica coated gold nanoparticles (PFH-NEs-scAuNPs) in order to give both stable and enhanced signals for cancer imaging by increasing vaporization of the emulsions into bubbles through the process of optical droplet vaporization (ODV). The resulting perfluorohexane bubbles could be imaged using nonlinear ultrasound (NL US) which significantly increases the signal to noise ratio due to the nonlinear scattering properties of oscillating bubbles. The NL US signals from PFH bubbles were found to be more stable compared to conventional bubbles used for contrast imaging. In addition, the vaporization of PFH NEs into bubbles was shown to cause significant cancer cell death reflecting the theranostic capabilities of the formed PFH bubbles. Since cell death is initiated with laser excitation of PFH-NEs-scAuNPs, these nanoparticles can specifically target cancer cells once they have accumulated at the tumor region. Due to the type of theranostic agent and imaging modality used, the PFH-NEs-scAuNPs can be used to provide higher specificity compared to other agents for locating the tumor region by minimizing tissue specific signals while at the same time being used to treat cancer.

Published: November 2024

The high frequency backscatter from cells with a nucleus to cell volume ratio of 0.50 cannot be adequately modeled as a homogeneous sphere. It was hypothesized that the cytoplasm of such cells is of fluid nature. This work attempts to model the ultrasound backscatter (10-62 MHz) from some non-nucleated biological specimens. This was done by measuring the backscatter response from individual sea urchin oocytes and comparing it to theoretical predictions in both the time and frequency domains. A good agreement was found between the experimental and theoretical results suggesting that the non-nucleated oocytes are of fluid nature.

Decision-makers need to act now to halt biodiversity loss, and ecologists must provide them with relevant species interaction indicators to inform on community- and ecosystem-level changes. Yet, the integration of ecological networks into conservation is still virtually nonexistent. Here, we discuss challenges and opportunities related to uncertainty, interpretability and relevance of network metrics applied to conservation. We argue that existing data and methodologies are sufficient to generate network information usable for conservation, and to overcome existing challenges. Interaction network indicators must meet criteria important to decision-makers and be tied to specific conservation goals, which requires academics to better engage with practitioners. We suggest network robustness as an indicator for biodiversity management and showcase it in a workflow to inform decision-making.

Insect declines have been reported globally but whilst island ecosystems are potentially facing exacerbated challenges, no long-term studies (LTER) have confirmed this trend. This study utilises the first available LTER data on island invertebrates, targeting epigeal and canopy arthropods from the Azores, and covering over 20 years in three distinct sampling events from 30 standard sites. We investigate changes in abundance, biomass, and species richness within these arthropod communities, focusing on the proportions of endemic and introduced species, and trends among single-island endemics and strict forest-dependent endemics. We reveal no significant declines in overall abundance, biomass, or richness of endemic or non-endemic native arthropod populations, although we observe considerable variability between sampling events in both epigeal and canopy communities. Of the species analysed, 26% experienced declines, 15% increased in abundance, and 59% showed no change. We found minimal evidence for the rapid spread of introduced species or their increasing influence in the communities, nor any exotic-driven extirpation of endemic species. Interestingly, forest-dependent endemic species declined at a lower rate than anticipated, suggesting that the extinction debt for these species may be less severe than previously thought. The three-decade-long conservation of Azorean native forests may contribute to these unexpectedly stable populations.
Understanding Host-Microbiome Evolution through the Lens of Evolutionary Theory: New Tricks for Old Dogs

Published: November 2024

All plants and animals are host to a community of microorganisms, their microbiomes, that have crucial influences on the life history and performance of their hosts. Despite the importance of such host-microbiome relationships, relatively little is known about the role microbiomes play in mediating evolution of the host as well as entire host-microbe assemblages. This knowledge gap is partly due to the lack of theoretical frameworks that generate testable predictions on the evolutionary dynamics of host-microbiome systems. In this Perspective, we argue that the foundation for such frameworks exists in evolutionary theory. We highlight four examples of theoretical models - niche construction, indirect genetic effects, maternal effects and multilevel selection – that capture important aspects of host-microbiome evolution. We outline how each of these frameworks can provide key insights into the involved evolutionary dynamics, while also suggesting expansions of current theory to incorporate processes unique to host-microbe assemblages, for instance focusing on nuances in microbiome transmission and ecological microbial community dynamics. Expanding evolutionary theory to accommodate host-microbiome systems is key for a more integrative understanding of evolution, which is undoubtedly impacted by the association with microorganisms across the tree of life, guiding future empirical research on the function and evolution of these omnipresent interactions.

Authors: Fadhila Arni Ismi , Tan Sukmawati Tansil
Published: November 2024

ABSTRACT Acne Vulgaris (AV) is a chronic inflammatory skin disease affecting the pilosebaceous glands. Acne Vulgaris commonly occurs in adolescents due to hormonal fluctuations that stimulate the sebaceous glands to produce more sebum. The face, back, chest, and shoulder areas often display a predilection for AV. The aim of this study is to assess the facial sebum levels of students at SMAN 75 North Jakarta predisposed to acne vulgaris. This study used a cross-sectional design and was conducted at SMAN 75 North Jakarta in January 2024. Sampling was carried out using non-random consecutive sampling. Data obtained from the samples will be processed and analyzed using SPSS 22.0. Sebum levels were measured using a skin analyzer SK-08 on the left and right sides of the face. The characteristics of the AV group in students of SMAN 75 North Jakarta showed severe acne as many as 37 people (8.20%), moderate acne as many as 100 people (6.57%), and mild acne as many as 33 people (5.75%). Based on the Kruskal-Wallis statistical test, there was a significant difference in the average oil content between the three acne severity groups (P-value <0.001). These results indicate that increased sebum levels are associated with increased severity of acne vulgaris. Keywords: Acne Vulgaris, Sebum Levels, Pilosebasea Glands, Skin Analyzer  ABSTRAK Akne Vulgaris (AV) adalah penyakit kulit inflamasi kronis yang menyerang kelenjar pilosebasea.

Published: November 2024

ABSTRACT This study aims to analyse global trends in research related to microplastic contamination and river water quality using a bibliometric approach. Microplastics have become one of the most pressing environmental issues in recent decades, mainly due to their significant impact on aquatic ecosystems and potential harm to human health. Along with the increasing attention to this issue, the scientific literature related to microplastics and river water quality has grown rapidly. However, a thorough understanding of the distribution of research, relationships between topics, as well as potential research gaps is still needed to direct future research more effectively. This study used a literature search method through the Publish or Perish app, with keywords including "microplastics," "water quality," "water pollution," "microplastic contamination," and "river." The search was conducted from 2014 to 2024, resulting in 50 relevant articles for further analysis. The data obtained was then processed using VOSviewer to map and visualise the bibliometric network, identify key clusters, and evaluate the temporal progression of these research topics. The resulting visualisations, including network visualisation, overlay visualisation, and density visualisation, provide deep insights into how key terms are connected and evolve in the literature. The analysis showed that research on microplastics in the context of rivers and water quality is heavily dominated by a few key terms such as "microplastic," "river," and "water," indicating the high level of scientific attention on this topic. In addition, it was found that research often focuses on the distribution of microplastics, physicochemical parameters of water, and sources of contamination. However, there are some significant research gaps, especially related to the effect of salinity on microplastic distribution, the accumulation of microplastics in river sediments, and the role of wastewater treatment plants in preventing the spread of microplastics to aquatic ecosystems. The conclusion of this study is that despite significant progress in understanding the distribution and impacts of microplastics, many aspects still require further research. In particular, research on the long-term impacts of microplastics and their interactions with other environmental components should be further enhanced. The findings are expected to provide guidance for future researchers to explore under-explored areas and contribute to better environmental management. Keywords: Microplastic, Water Quality, River Pollution, Bibliometric Analysis, Environmental Research
Public Libraries for Immigrant Communities
Authors: Naderi B. Ramin
Published: November 2024

U.S. immigration policies marginalize and inferiorize non-Northern or Western European immigrants (Al-khersan & Shahshahani, 2022). This integrative literature review, framed through the lens of critical librarianship, examines the role of public libraries and librarians in serving and developing immigrant communities within the context of U.S. immigration policies. A qualitative content analysis of 38 articles reveals that while public libraries play crucial roles for immigrants upon entry into the United States, their services fall short of including the heterogeneity of immigrants and fostering lasting relationships with immigrant populations. The roots of this impediment can be traced to the deficit-based paradigm and need-orientedness of the public library’s approach to immigrants, initiated by the Americanization movement (Ndumu & Ramnine, 2021). A gap was identified, indicating that empirical research is needed to interrogate the leadership roles of public libraries in community development alongside immigrant groups in the U.S.
