Effects of three biaxially oriented polypropylene (BOPP) microperforated films of different transmission rates [3 (M50), 5 (M30), and 16 (M10) holes; Ø = 100 µm] on the maintenance of colour and bioactive compounds profile of three fig cultivars were studied in comparison with macroperforated film (5 holes; ø = 9 mm) during cold storage. Figs from 'Cuello Dama Negro', 'Cuello Dama Blanco' and 'San Antonio' cultivars were stored at 0 ℃ and 90–95% relativity humidity in the dark for 21 days; and were sampled at 0, 7, 14, 17, and 21 days. Skin and flesh colour, total antioxidant activity (both hydrophilic and lipophilic fractions), chlorophylls and phenolic compounds were measured. Results revealed that microperforated film packaging (especially M50) helped maintaining skin colour during storage, delayed senescence of fruit, and enhanced the concentrations of cyanidin 3-O-rutinoside (up to ninefold increase in the skin) and quercetin 3-O-rutinoside (2- to 20-fold increase in concentration in the skin, and up to fivefold increase in the flesh), the main phenolic compounds found in dark skin figs. On another part, this was the first time that lipophilic antioxidant activity was measured in figs, obtaining values between 0.25 and 0.61 mmol kg−1 for skin and flesh, respectively. Obtained results were in concordance with other fruits studied by other authors. [ABSTRACT FROM AUTHOR]

Background While substantial anatomical study has been pursued throughout the human body, anatomical study of the human lymphatic system remains in its infancy. For microsurgeons specializing in lymphatic surgery, a better command of lymphatic anatomy is needed to further our ability to offer surgical interventions with precision. In an effort to facilitate the dissemination and advancement of human lymphatic anatomy knowledge, our teams worked together to create a map. The aim of this paper is to present our experience in mapping the anatomy of the human lymphatic system. Methods Three steps were followed to develop a modern map of the human lymphatic system: (1) identifying our source material, which was "Anatomy of the human lymphatic system," published by Rouvière and Tobias (1938), (2) choosing a modern platform, the Miro Mind Map software, to integrate the source material, and (3) transitioning our modern platform into The Human BioMolecular Atlas Program (HuBMAP). Results The map of lymphatic anatomy based on the Rouvière textbook contained over 900 data points. Specifically, the map contained 404 channels, pathways, or trunks and 309 lymph node groups. Additionally, lymphatic drainage from 165 distinct anatomical regions were identified and integrated into the map. The map is being integrated into HuBMAP by creating a standard data format called an Anatomical Structures, Cell Types, plus Biomarkers table for the lymphatic vasculature, which is currently in the process of construction. Conclusion Through a collaborative effort, we have developed a unified and centralized source for lymphatic anatomy knowledge available to the entire scientific community. We believe this resource will ultimately advance our knowledge of human lymphatic anatomy while simultaneously highlighting gaps for future research. Advancements in lymphatic anatomy knowledge will be critical for lymphatic surgeons to further refine surgical indications and operative approaches. [ABSTRACT FROM AUTHOR]

PERIPHERAL nervous system , *NERVOUS system , *NERVE tissue , *GANGLIA , *ELECTRON microscopy - Abstract
The peripheral nervous system of the octopus is among the most complex of any animal. In each arm, hundreds of serial ganglia form a central core of nervous tissue processing sensory input, issuing motor commands, and exchanging information with the central brain. 1,2,3,4,5 In addition to the central cord, there are two other types of neural elements: fine intramuscular nerve cords (INCs) 6,7 and small sucker ganglia at the base of each sucker. 2,6,8,9 Connections between these different elements and the structural organization of the arm nervous system remain poorly understood, despite decades of interest and a more recent explosion of studies of the cephalopod nervous system. 8,10,11,12,13,14,15 Here, we use serial blockface electron microscopy to reconstruct large volumes of an arm from Octopus bocki at the base and toward the tip, mapping connections between the various neural elements and their relationship to the muscle and skin. We show that the ganglia follow an alternating mirror-image pattern along the arm, where the left or right-sided location of successive suckers determines ganglionic orientation. We also describe previously unrecognized patterns in (1) continuity of oblique connectives between the INCs that encircle the arm; (2) repeatable structures of the major blood vessel branches and nerve connectives within each ganglion; (3) clustering of rare, unusually large neurons within the cell body layers; and (4) division of the cortex into repeating columns. These new findings from the first 3DEM reconstruction of the arm should greatly facilitate future studies of octopus neurobiology, particularly sensori-motor integration and arm control. [Display omitted] • 3D-EM of the octopus's arm at the tip and base reveals new details of organization • High similarity among ganglia structures, in alternating symmetry down the arm • Oblique connectives allow spiraling connectivity between left and right sides • Clustered large cells and columnar organization suggest subdivision within cortex Neacsu and Crook reveal symmetrical organization within the arm nervous system of Octopus bocki , using 3DEM to reconstruct neural and vascular tissues of an arm at the base and tip. New detail of connectives and nerve patterning offers insights into organization, structure, and function of this highly complex peripheral nervous system. [ABSTRACT FROM AUTHOR]

Octopus arms, notable for their complex anatomy and remarkable flexibility, have sparked significant interest within the neuroscience community. However, there remains a dearth of knowledge about the neurochemical organization of various cell types in the arm's nervous system. To address this gap, we used hybridization chain reaction (HCR) to identify distinct neuronal types in the axial nerve cords of the pygmy octopus, Octopus bocki , including putative dopaminergic, octopaminergic, serotonergic, GABAergic, glutamatergic, cholinergic, and peptidergic cells. We obtained high-resolution multiplexed fluorescent images at 0.28 × 0.28 × 1.0 μm voxel size from 10 arm base and arm tip cross sections (each 50 μm thick) and created three-dimensional reconstructions of the axial ganglia, illustrating the spatial distribution of multiple neuronal populations. Our analysis unveiled anatomically distinct and molecularly diverse scattered neurons, while also highlighting multiple populations of dense small neurons that appear uniformly distributed throughout the cortical layer and potential glial cells in the neuropil. Our data provide new insights into how different types of neurons may contribute to an octopus's ability to interact with its environment and execute complex tasks. In addition, our findings establish a benchmark for future studies, allowing pioneering exploration of octopus arm molecular neuroanatomy and offering exciting new avenues in invertebrate neuroscience research. [Display omitted] • 3D octopus arm cord maps reveal stratified monoaminergic and peptidergic neurons • Significant neurochemical differences between the arm tip and base ganglia • Cholinergic and glutamatergic neurons are abundant; GABAergic neurons are scarce • Novel identification of neuronal cotransmission and possible protoplasmic glia Winters-Bostwick et al. reveal complex neurochemical organization within the arm nerve cord of Octopus bocki , using HCR to identify diverse neuronal types. High-resolution 3D imaging and reconstruction demonstrate spatial distribution of cell types, offering new insights into octopus neuroanatomy and enhancing understanding of limb function.

INTENSIVE care patients , *GLYCEMIC control , *INFUSION therapy , *BLOOD sugar ,INSULIN therapy effectiveness - Abstract
Introduction: Insulin infusion therapy is applied for all Intensive Care Unit (ICU) patients who have hyperglycaemia regardless of diabetic history or status. Unfortunately, improper glycaemic control and patient dynamics may cause hypoglycaemia episodes. The purpose of this study was to categorise ICU patients by considering potential variables that may affect blood glucose for the effectiveness of insulin infusion therapy. Materials and methods: Thirty-three diabetes mellitus ICU patients who received insulin infusion therapy and had at least 12 blood glucose readings throughout their ICU stay were selected for this study. Variables of a fraction of inspired oxygen (FiO2) and mean arterial pressure (MAP) were chosen for clustering this cohort using K-means and density-based spatial clustering of applications with noise (DBSCAN) techniques. Results: he outcomes showed K-means produced four clusters for each variable, while DBSCAN provides unstandardised clusters, nine for FiO2 and four for MAP. K-means is more ap-propriate for this cohort, validated by Silhouette analysis and clinically applicable cluster numbers for both variables. The clusters obtained from K-means for FiO2 were > 0.5, > 0.4, > 0.3, and = 0.3, while for MAP were > 98.5 mmHg, 86 mmHg, > 75 mmHg, and = 75 mmHg. Conclusion: The formation of these clusters is expected to improve the effectiveness of the insulin infusion protocol while addressing personalised treatment for the categorised patients.

CONTROLLED atmosphere packaging , *COLD storage , *MALIC acid , *VIOLA , *FLOWERS - Abstract
Edible flowers are becoming increasingly popular as food products, since they give aroma, color, and visual appeal and are also health-promoting compounds. However, they are a highly perishable product, thus post-harvest technologies are needed to extend their marketability. In this study, active (N2: 100%) and passive modified atmosphere packaging (MAP) technologies were applied to three edible flower species, namely Begonia grandiflora 'Viking', Tropaeolum majus, and Viola cornuta, stored at 4 °C. Even if the flowers' quality decay occurred differently according to the species, active MAP better maintained petal colors and slowed down the edible flowers' decay than passive MAP by decreasing flower respiration in all three species and sugars consumption in begonia; there was weight loss in nasturtium, and better preserved total phenolic content in begonia and viola. Coupling cold storage with active MAP can be an effective method to extend edible flowers' post-harvest life. [ABSTRACT FROM AUTHOR]

Background: Otosclerosis is one of the most frequent causes of conductive hearing loss in adults. Surgical treatment is considered to be the gold standard for this disease. Endoscopic stapedectomy is a new approach for the treatment of otosclerosis that requires a bloodless field. Aim of the Study: To determine whether the routine use of β blockers as a premedication can improve the operative field in endoscopic stapedectomy or not. Patients and Methods: Sixty patients aged from 18 to 50 years, undergoing endoscopic stapedectomy, were included in this prospective, randomized, double blinded, placebo-controlled study. Patients were randomly assigned to receive either metoprolol 100 mg (group 1) or a placebo, vitamin tablet, (group 2) 60 min before surgery. Results: The age, gender, body weight and ASA physical status were comparable between the two groups. The average blood loss in the placebo group was significantly greater than in the metoprolol group, but the time of operation in the metoprolol group was not significantly shorter. The surgical field was assessed using the Fromme-Boezaart scale, and those who received metoprolol had considerably cleaner (p0.001) surgical fields. The mean arterial pressure (MAP) didn't differ statistically significant at basal measurement up to 30 min after anesthesia induction while it was significantly lower in the metoprolol group after 30 min of induction up to end of surgery (p < 0.001). The heart rate was also significantly lower (p < 0.001) in patients who received metoprolol from prior to anesthesia induction up to end of surgery. Conclusion: metoprolol significantly improves visual clarity and hemodynamics during endoscopic stapedectomy. [ABSTRACT FROM AUTHOR]

1. Recent research has shown that encapsulated raspberry powder (RP) is a natural colourant for foodstuffs. However, no research has been conducted on its use in chicken nuggets. In addition, the effect of RP on products with and without phosphate addition is unknown. This study assessed the effects of RP (control, 0.5%, 1.0%) and phosphate (0.0%, 0.3%) on the pH and colour quality properties of nuggets. 2. In the production of RP, red raspberry (Rubus ideaus L.) juices were encapsulated using maltodextrin in a spray-dryer. Antioxidant activity, total anthocyanin, total phenolics, colour, moisture and pH analyses of the RP were performed. 3. Nuggets were packaged in modified atmosphere packaging (MAP; 40%CO2 + 60%N2) and were stored at 2.0 ± 0.5°C for 120 d. The pH and external and internal surface colour (L*, a*, b*, C* and h) values were measured on d 0, 15, 30, 45, 60, 75, 90, 105 and 120 of storage. 4. The addition of phosphate increased the pH in the samples, while these decreased with the addition of RP (p < 0.05). During storage, the highest pH were seen in the phosphate samples and the lowest in the nuggets with 1.0% RP addition (p < 0.05). 5. With the addition of phosphate, the external surface a* value of nuggets increased (p < 0.05). Depending on the level of RP added to the nuggets, the external surface L* value decreased and a* and b* values increased (p < 0.05). After d 30 of storage, the a* value increased in the samples with RP addition and this increase was higher in the with phosphate nuggets (p < 0.05). 6. The internal surface a* value increased with the addition of RP during nugget production (p < 0.05). The increase in a* value was greater in samples with added phosphate (p < 0.05). During storage, the highest a* values were seen in nuggets treated with phosphate + 0.1% RP (p < 0.05). The addition of RP to chicken nugget emulsion improved redness, colour stability and shelf life. [ABSTRACT FROM AUTHOR]

The YOLOv8 model has high detection efficiency and classification accuracy in detecting commutator surface defects, aimed at the problem of low working efficiency of a commutator, caused by commutator surface defects. First, the theoretical framework of Region-based Convolutional Neural Networks (R-CNN), spatial pyramid pooling (SPP)-net, Fast R-CNN, and Faster R-CNN is introduced, and the detection principle and process are described in detail. Secondly, the principle of the YOLOv8 network structure, head structure, neck structure, and C2f module are explained, and the loss function is described. The average precision of the proposed algorithm for detecting cracks and small points is more than 98%, and the frames per second (FPS) is 27. The detection results are mapped to the original image, and the visualization of the commutator surface defect detection is obtained, which has a higher robustness, accuracy, and real-time performance than the R-CNN, SPP-net, Fast R-CNN, and Faster R-CNN algorithms.

Zhang, Yang, Li, Haokang, Li, Shuo, Li, Yifan, and Ding, Yuanhong
- Abstract
Nitrate can be electrolyzed mainly into N2, but the generated ammonia, as its secondary intermediate, is soluble and remained in the wastewater yet, which affects negatively the degradation of nitrate and total nitrogen. In this work, an electrolytic reactor constructed with Ti/RuSn anode and Fe cathode, was applied to electrolyze nitrate, and magnesium chloride was used as electrolyte and precipitant simultaneously, while disodium hydrogen phosphate (DSP) was added only as precipitant of ammonia. The results indicated that, most part of generated ammonia could be precipitated as magnesium ammonium phosphate (MAP) and some residual ammonia may be transformed into N2 by breakpoint chlorination. Thus, the nitrate and total nitrogen (TN) degradation efficiencies could be enhanced obviously by the combined electrolysis precipitation process. [ABSTRACT FROM AUTHOR]

This study aimed to investigate effects of epigallocatechin gallate (EGCG) on blood pressure (BP) and autonomic nervous system, indicated by 5-min heart rate variability (HRV) measurement in obese subjects, and determine correlations of BP with metabolic factors. In a double-blind, randomized controlled trial, obese subjects (n = 30) were randomly allocated to receive 150 mg EGCG (n = 15) or placebo (n = 15) twice a day without dietary restrictions. After 8-week EGCG treatment, systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) significantly decreased, while the low-frequency (LF) to high-frequency power (HF) ratio (LF/HF ratio) significantly increased (P < 0.05 all), indicating a shift toward sympathetic dominance, either directly or indirectly after BP lowering. SBP had positive correlations with obesity parameters, leptin, insulin, and insulin resistance but had a negative correlation with insulin sensitivity. DBP was positively correlated with age and HF in normalized unit, but negatively correlated with height and LF in ms2. High-density lipoprotein cholesterol (HDL-C) was negatively correlated with SBP, DBP, and MAP reflecting its protective effect against elevated BP. In conclusion, the 8-week EGCG treatment decreased BP and increased the LF/HF ratio, reflecting increased sympathetic activity, either a direct EGCG effect or an indirect compensatory response following BP reduction.

Yellow mosaic disease (YMD) caused by several begomoviruses is one of the major constraints of over a dozen leguminous crops worldwide, particularly in Asian and Southeast Asian countries. The present study aimed to investigate the distribution, diversity and prevalence of begomoviruses associated with YMD in leguminous hosts in five agro-climatic zones of India, to assess the extent of their geographical presence and develop location and crop-specific distribution maps. One hundred and seventy-four leguminous plant samples were tested from 32 locations in India to detect YMD-causing viruses. Additionally, publicly available data were incorporated into this study to provide a comprehensive overview of their distribution in India. This resulted in 581 reports on the DNA-A component representing 119 locations, which were also utilized to depict the distribution of YMD-causing viruses on a map of India. In this study, 117 full-length DNA-A and 103 DNA-B components were successfully characterized, representing the detected mungbean yellow mosaic India virus (MYMIV), mungbean yellow mosaic virus (MYMV), and horsegram yellow mosaic virus in the collected samples. Phylogenetic analysis of isolates of these species showed no differentiation based on location in India. Diversity indices revealed the abundance (55.9%) and dominance (0.56) of MYMIV across 119 locations. These findings hold significant implications for legume researchers, offering insights into disease prevalence and geographic distribution. Furthermore, the distribution of YMD-causing viruses in different agro-climatic zones will help researchers in developing zone-specific YMD-resistant cultivars of the legume crops and would facilitate effective disease management options.

We consider a two-group social conflict under the corporates' research and development (R&D) business processes. Conflict participants are divided into two groups depending on their attitude to new ideas, technologies, and behavioral style for R&D creative problems—innovators and adapters. We reveal the contradiction that arises between the need to include both types of employees in one project team and their objectively antagonistic positions regarding the methods and approaches to R&D processes. The proposed research methodology is based on a modern post-non-classical paradigm formed on the principles of coherence, interdisciplinarity, openness, and nonlinearity, as well as a sociophysical approach to the social conflicts modeling. We use the general theories of magnetism, paramagnetism, and functions of P. Langevin and L. Brillouin to describe the dynamics of group participants' preferences regarding the style of conflict behavior. The analogy of paramagnetism, consisting in the orienting effect of the magnetic field, is used to describe social groups interactions that have not only their own interests, but are also influenced by the opinions of opposite social groups. A two-dimensional, four-parameter map represents the dynamics of group conflict. Modeling results show that regardless of the initial states and with certain parameters of intra-group and intergroup interactions, the trajectories eventually converge to an attractor (limit cycle) in a two-dimensional space. No non-periodic or chaotic modes are identified in the two-group conflict, which determines the controllability of the described conflict. The results of the simulation experiments are used as decision support and contradictions resolution aimed at forming the required modes of the corporates' research and development business processes and ensuring the group participants' cohesion and depolarization. The results of testing the model at an industrial enterprise are presented. [ABSTRACT FROM AUTHOR]

The paper introduces a new FireAndSmoke open dataset comprising over 22,000 images and 93,000 distinct instances compiled from 1200 YouTube videos and public Internet resources. The scenes include separate and combined fire and smoke scenarios and a curated set of difficult cases representing real-life circumstances when specific image patches may be erroneously detected as fire/smoke presence. The dataset has been constructed using both static pictures and video sequences, covering day/night, indoor/outdoor, urban/industrial/forest, low/high resolution, and single/multiple instance cases. A rigorous selection, preprocessing, and labeling procedure has been applied, adhering to the findability, accessibility, interoperability, and reusability specifications described in the literature. The performances of the YOLO-type family of object detectors have been compared in terms of class-wise Precision, Recall, Mean Average Precision (mAP), and speed. Experimental results indicate the recently introduced YOLO10 model as the top performer, with 89% accuracy and a mAP@50 larger than 91%. [ABSTRACT FROM AUTHOR]

The list of standard abbreviations for JDS is available at adsa.org/jds-abbreviations-24. Nonstandard abbreviations are available in the Notes. Mycobacterium avium ssp. paratuberculosis (MAP) is the bacterium responsible for causing Johne's disease (JD), which is endemic to dairy cattle and also implicated in the etiology of Crohn's disease. The difficulty in diagnosing asymptomatic cows for JD makes this disease hard to control. Johne's disease is considered a priority under the One Health approach to prevent the spread of the causative agent to humans. Environmental screening is a strategic approach aimed at identifying dairy herds with animals infected with MAP. It serves as the initial step toward implementing more intensive actions to control the disease. Quantitative PCR (qPCR) technology is widely used for diagnosis. Given that genome sequencing is now much more accessible than ever before, it is possible to target regions of the MAP genome that allow for the greatest diagnostic sensitivity and specificity. The aim of this study was to identify among the published qPCR assays targeting IS 900 the more cost-effective options to detect MAP and to validate them in the diagnostic context of JD. Mycobacterium avium ssp. paratuberculosis IS 900 is a prime target because it is a multicopy genetic element. A total of 136 publications have reported on the use of IS 900 qPCR assays over the past 3 decades. Among these records, 29 used the SYBR Green chemistry, and 107 used TaqMan technology. Aside from the 9 reports using commercial assays, 72 TaqMan reports cited previously published work, leaving us with 27 TaqMan qPCR designs. Upon closer examination, 5 TaqMan designs contained mismatches in primer or probe sequences. Additionally, others exhibited high similarity to environmental microorganisms or non-MAP mycobacteria. We assessed the performance of 6 IS 900 qPCR designs and their sensitivity when applied to clinical or environmental samples, which varied from 4 to 56 fold overall. Additionally, we provide recommendations for testing clinical and environmental samples, as certain strategies used previously should be avoided due to poor qPCR design (e.g., the presence of mismatches) or a lack of specificity.

Tightness remains the primary goal in all modern estimation bounds. For very weak signals, tightness is enabled by appropriately selecting the prior probability distribution and bound family. While current bounds in global navigation satellite systems (GNSSs) assess the performance of carrier frequency estimators under Gaussian or uniform assumptions, the circular nature of frequency is overlooked. Of all bounds in the Bayesian framework, the Weiss--Weinstein bound (WWB) stands out because it is free from regularity conditions or restrictions on the prior distribution. Therefore, the WWB is extended for the current frequency estimation problem. A divide-and-conquer type of hyperparameter tuning method is developed to mitigate issues of computational complexity for the WWB family while enhancing tightness. Synthetic results show that for a von Mises prior probability distribution, the WWB provides a bound up to 22.5% tighter than the Ziv--Zakaï bound when the signal-to-noise ratio varies between -3.5 dB and -20 dB, where the GNSS signal is deemed extremely weak.

Modified atmosphere package (MAP), as a practical, economic, and easy to operate food package technique, has experienced a rapid development in both scientific and industrial communities. In recent years, given the superiority of super-atmospheric O2 (SO) MAP in preserving fruits and vegetables relative to low O2 and/or high CO2 MAP, SO MAP is back on the radar of researchers. This paper systematically reviews recent development on application of SO MAP and improved strategies to fruit and vegetable preservation in the last 15 years, possible mechanisms concerning their positive and negative effects, and challenges and future perspectives for SO MAP.

Mycobacterium avium subsp. paratuberculosis (MAP) causes Johne's disease, or paratuberculosis (PTB) in ruminants, besides having zoonotic potential. It possibly changes the gut microbiome, but no conclusive data are available yet. This study aimed at investigating the influence of MAP on the faecal microbiome of cattle naturally infected with PTB. In a follow up period of 10 months, PTB status was investigated in a herd of dairy cattle with history of clinical cases. Each animal was tested for MAP infection using serum and milk ELISA for MAP anti-bodies and IS900 real-time PCR and recombinase polymerase amplification assays for MAP DNA in the faeces and milk monthly for 4 successive months, then a last one after 6 months. The faecal samples were subjected to 16S rDNA metagenomic analysis using Oxford Nanopore Sequencing Technology. The microbial content was compared between animal groups based on MAP positivity rate and production status. All animals were MAP positive by one or more tests, but two animals were consistently negative for MAP DNA in the faeces. In all animals, the phyla firmicutes and bacteroidetes were highly enriched with a small contribution of proteobacteria, and increased abundance of the families Oscillospiraceae, Planococcaceae, and Streptococcacaceae was noted. Animals with high MAP positivity rate showed comparable faecal microbial content, although MAP faecal positivity had no significant effect (p > 0.05) on the microbiome. Generally, richness and evenness indices decreased with increasing positivity rate. A significantly different microbial content was found between dry cows and heifers (p < 0.05). Particularly, Oscillospiraceae and Rikenellaceae were enriched in heifers, while Planococcaceae and Streptococcaceae were overrepresented in dry cows. Furthermore, abundance of 72 genera was significantly different between these two groups (p < 0.05). Changes in faecal microbiome composition were notably associated with increasing MAP shedding in the faeces. The present findings suggest a combined influence of the production status and MAP on the cattle faecal microbiome. This possibly correlates with the fate of the infection, the concern in disease control, again remains for further investigations. [ABSTRACT FROM AUTHOR]

Abstract Nitrate can be electrolyzed mainly into N2, but the generated ammonia, as its secondary intermediate, is soluble and remained in the wastewater yet, which affects negatively the degradation of nitrate and total nitrogen. In this work, an electrolytic reactor constructed with Ti/RuSn anode and Fe cathode, was applied to electrolyze nitrate, and magnesium chloride was used as electrolyte and precipitant simultaneously, while disodium hydrogen phosphate (DSP) was added only as precipitant of ammonia. The results indicated that, most part of generated ammonia could be precipitated as magnesium ammonium phosphate (MAP) and some residual ammonia may be transformed into N2 by breakpoint chlorination. Thus, the nitrate and total nitrogen (TN) degradation efficiencies could be enhanced obviously by the combined electrolysis precipitation process.

ABSTRACT: Mycobacterium avium ssp. paratuberculosis (MAP) is the bacterium responsible for causing Johne's disease (JD), which is endemic to dairy cattle and also implicated in the etiology of Crohn's disease. The difficulty in diagnosing asymptomatic cows for JD makes this disease hard to control. Johne's disease is considered a priority under the One Health approach to prevent the spread of the causative agent to humans. Environmental screening is a strategic approach aimed at identifying dairy herds with animals infected with MAP. It serves as the initial step toward implementing more intensive actions to control the disease. Quantitative PCR (qPCR) technology is widely used for diagnosis. Given that genome sequencing is now much more accessible than ever before, it is possible to target regions of the MAP genome that allow for the greatest diagnostic sensitivity and specificity. The aim of this study was to identify among the published qPCR assays targeting IS900 the more cost-effective options to detect MAP and to validate them in the diagnostic context of JD. Mycobacterium avium ssp. paratuberculosis IS900 is a prime target because it is a multicopy genetic element. A total of 136 publications have reported on the use of IS900 qPCR assays over the past 3 decades. Among these records, 29 used the SYBR Green chemistry, and 107 used TaqMan technology. Aside from the 9 reports using commercial assays, 72 TaqMan reports cited previously published work, leaving us with 27 TaqMan qPCR designs. Upon closer examination, 5 TaqMan designs contained mismatches in primer or probe sequences. Additionally, others exhibited high similarity to environmental microorganisms or non-MAP mycobacteria. We assessed the performance of 6 IS900 qPCR designs and their sensitivity when applied to clinical or environmental samples, which varied from 4 to 56 fold overall. Additionally, we provide recommendations for testing clinical and environmental samples, as certain strategies used previously should be avoided due to poor qPCR design (e.g., the presence of mismatches) or a lack of specificity.

Objective To analyze the structure of CD36, search the possible B cell epitopes and prepare multi-antigen peptides(MAP) with B cell epitopes, so as to provide a preliminary experimental basis for the preparation of CD36 antibodies using MAP with B cell epitopes. Methods The potential B cell epitopes of CD36 were analyzed by bioinformatics methods, including physical and chemical properties, secondary structure, potential phosphorylation and glycosylation sites. Eight-branch MAP with CD36 B cell epitopes were synthesized by FMOC using polylysine as the core matrix. The purity of MAPs was analyzed by reverse high-performance liquid chromatography chromatography(RP-HPLC), and the molecular weight of MAPs was determined by mass spectrometry. Results CD36 is a stable and hydrophilic alkaline protein, with multiple phosphorylation and glycosylation sites and strong antigenicity, and its secondary structure is mainly characterized by irregular curls. Four potential B cell epitopes were obtained and 4 MAPs containing potential B cell epitopes were prepared. RP-HPLC analysis showed that the purity of the MAPs were above 85%, and the molecular weight of 3 MAPs was consistent with the expected theoretical molecular weight. Conclusion CD36 on platelet has strong antigenicity. MAPs containing CD36 B cell epitopes can provide the experimental basis for the preparation and related research of CD36 antibodies.

Objective To observe the effect of deglycerolized red blood cells suspended in MAP on preservation and explore the most effective preservation method. Methods Concentrated red blood cells were prepared by centrifuging 400 mL of whole blood on the third day after collection. 40% compound glycerol solution was added using the ACP 215 automatic blood cell analyzer, and the resulting mixture was stored in an ultra-low temperature refrigerator at -65℃ for 30 days. After thawing and washing, it was equally separated into two bags. The control group received 0.9% sodium chloride solution, while the experimental group received MAP. Both groups were stored at 2-6℃. Hematological parameters, hemolysis indexes and cell metabolism indexes were measured on day 0, 1, 3, 5, 7 and 14 after storage. The quality changes of both groups were observed during the 14-day storage period. Results The quality of red blood cells in both groups was assessed through a panel of quality tests, including volume, hemoglobin content, free hemoglobin content, white blood cell residue, glycerin residue and sterility. These results met the Quality Requirements outlined in the "Quality Requirements of Whole Blood and Component Blood" (GB18469-2012), Hematocrit, red blood cell count, Hb recovery rate after washing and MCV meet the detection limit outlined in the "Expert Consensus on Quality Evaluation Indicators for Frozen Red Blood Cells", and the residual amount of platelets exceeds the detection limit(≤1%). There were no significant differences in RBC, Hct, MCV and hemoglobin between the two groups during the 14 day storage period. The level of free hemoglobin, hemolysis rate and K+ value increased in both groups over time. Significant differences in free hemoglobin were found on day 3, 5, 7 and 14 between the two groups(P

Abstract Mycobacterium avium subspecies paratuberculosis (MAP) is the causative agent of Johne’s Disease, a chronic granulomatous enteritis of ruminants. MAP establishes an infection in the host via the small intestine. This requires the bacterium to adhere to, and be internalised by, cells of the intestinal tract. The effector molecules expressed by MAP for this purpose remain to be fully identified and understood. Mammalian cell entry (mce) proteins have been shown to enable other Mycobacterial species to attach to and invade host epithelial cells. Here, we have expressed Mce1A, Mce1D, Mce3C and Mce4A proteins derived from MAP on the surface of a non-invasive Escherichia coli to characterise their role in the initial interaction between MAP and the host. To this end, expression of mce1A was found to significantly increase the ability of the E. coli to attach and survive intracellularly in human monocyte-like THP-1 cells, whereas expression of mce1D was found to significantly increase attachment and invasion of E. coli to bovine epithelial cell-like MDBK cells, implying cell-type specificity. Furthermore, expression of Mce1A and Mce1D on the surface of a previously non-invasive E. coli enhanced the ability of the bacterium to infect 3D bovine basal-out enteroids. Together, our data contributes to our understanding of the effector molecules utilised by MAP in the initial interaction with the host, and may provide potential targets for therapeutic intervention.

- Abstract
Cartographic representations are increasingly used to communicate sustainable mobility topics. Various formats of maps, such as static maps, mobile maps, map-based dashboards, story maps, and 3D map scenes, are created to illustrate mobility planning, traffic status, emissions, and travel behaviors. These maps are rich in cross-disciplinary information, target to diverse audiences, adopt various design technologies, and enable knowledge exchange among stakeholders of sustainable mobility. This paper examines how maps are used as communication tools for traffic and infrastructure to support decision-making and engage people to actively adapt their behavior towards green mobility. In this study, we (1) identified 48 maps that actively communicate sustainable mobility topics, (2) proposed a rigorous approach to assess maps that are created for communicating sustainable mobility topics, and (3) derived design recommendations for map makers to achieve more effective and efficient communication.

Like TNFα, IL-6 is upregulated in Crohn's disease (CD) especially in patients associated with Mycobacterium avium paratuberculosis (MAP) infection, and both cytokines have been targeted as a therapeutic option for the treatment of the disease despite the accepted partial response in some patients. Limited response to anti-IL-6 receptor-neutralizing antibodies therapy may be related to the homeostatic dual role of IL-6. In this study, we investigated the effects and the signaling mechanism of IL-6 involved in intestinal epithelial integrity and function during MAP infection using an in vitro model that consists of THP-1, HT-29 and Caco-2 cell lines. Clinically, we determined that plasma samples from MAP-infected CD patients have higher IL-6 levels compared to controls (P-value < 0.001). In CD-like macrophages, MAP infection has significantly upregulated the secretion of IL-6 and the shedding of (IL-6R) from THP-1 macrophages, P-value < 0.05. Intestinal cell lines (Caco-2 and HT-29) were treated with the supernatant of MAP-infected THP-1 macrophages with or without a neutralizing anti-IL-6R antibody. Treating intestinal Caco-2 cells with supernatant of MAP-infected macrophages resulted in significant upregulation of intestinal damage markers including claudin-2 and SERPINE1/PAI-1. Interestingly, blocking IL-6 signaling exacerbated that damage and further increased the levels of the damage markers. In HT-29 cells, MAP infection upregulated MUC2 expression, a protective response that was reversed when IL-6R was neutralized. More importantly, blocking IL-6 signaling during MAP infection rescued damaged Caco-2 cells from MAP-induced apoptosis. The data clearly supports a protective role of IL-6 in intestinal epithelia integrity and function especially in CD patients associated with MAP infection. The findings may explain the ineffective response to anti-IL6 based therapy and strongly support a therapeutic option that restores the physiologic level of IL-6 in patient's plasma. A new treatment strategy based on attenuation of IL-6 expression and secretion in inflammatory diseases should be considered. [ABSTRACT FROM AUTHOR]

The aim of this study was to analyze the influence of different packaging materials on the composition of the headspace (CO
2 and O2 ) of rennet cheeses packed in unit packaging under different modified atmosphere (MAP) conditions during a storage period of 90 days at 2 °C and 8 °C. The packaging materials comprised different combinations of BOPP—biaxially oriented polypropylene; PET—polyester; PE—polyethylene; PP—polypropylene; EVOH—ethylene–vinyl alcohol copolymer; PET—polyethylene terephthalate; and PA—polyamide. As the properties of the packaging material (foil) affect the gas conditions inside the packaging, it is important to study whether the modifications, i.e., properties and thickness, of the foils will result in significant differences in the composition of the headspace of packed cheeses. The CO2 content in the headspace of Gouda cheese packages ranged from 35% to 45%, while for Maasdamer and Sielski Klasyczny cheese, it varied between 55% and 65%. Throughout the storage period, the O2 content in the headspace of cheeses packaged in tested foils (1–5) did not exceed 0.5%. The type of foil used did not influence the modified atmosphere packaging (MAP) conditions. [ABSTRACT FROM AUTHOR]- Published

AIM To assess the association of Lactate, Lactate Albumin Ratio, Procalcitonin and Immature Platelet Fraction in comparison to SOFA Score on admission as marker of severity in sepsis patients OBJECTIVES • To assess Lactate / Albumin Ratio (LAR) in patients with sepsis. • To assess Lactate value in patients with sepsis . • To assess Procalcitonin (PCT) value in patients with sepsis. • To assess Immature Platelet Function (IPF) value in patients with sepsis. • To compare Lactate, LAR, PCT and IPF with SOFA score on admission in patients with sepsis for prognostication MATERIAL AND METHODS • Hospital based Observational Cross-Sectional Study was conducted at Mahatma Gandhi Hospital, Jaipur between September 2022 to December 2023. Data of 180 patients was collected according to inclusion criteria. Sepsis biomarkers that is Lactate, LAR, IPF, PCT were calculated and were compared to SOFA score at the time of admission for the purpose of prognostication. RESULT These intra-group analyses underscore the nuanced interactions between biomarkers and organ dysfunction severity as assessed by SOFA scores in sepsis. While Procalcitonin demonstrated significant associations, highlighting their clinical relevance in stratifying disease severity, Lactate, Lacto-albumin ratio and IPF showed more variable associations. CONCLUSION In this study all four markers positively correlated with SOFA score, that is the level of markers increased along with severity of sepsis. But our study particularly identifies significant associations: SOFA scores correlate significantly with procalcitonin. The biomarkers of sepsis used in our study that is Lactate, Lactate Albumin Ratio (LAR), Immature Platelet Fraction (IPF), Procalcitonin (PCT) can be used to enhance early risk stratification and guide more tailored therapeutic interventions for septic patients.

Estimating the calorie content of fruits is critical for weight management and maintaining overall health as well as aiding individuals in making informed dietary choices. Accurate knowledge of fruit calorie content assists in crafting personalized nutrition plans and preventing obesity and associated health issues. In this paper, we investigate the application of deep learning models for estimating the calorie content in fruits from digital images, aiming to provide a more efficient and accurate method for nutritional analysis. We create a dataset comprising images of various fruits and employ random data augmentation techniques during training to enhance model robustness. We utilize the RT-DETR model integrated into the ultralytics framework for implementation and conduct comparative experiments with YOLOv10 on the dataset. Our results show that the RT-DETR model achieved a precision rate of 99.01% and mAP50-95 of 94.45% in fruit detection from digital images, outperforming YOLOv10 in terms of F1- Confidence Curves, P-R curves, precision, and mAP. Conclusively, in this paper, we utilize a transformer architecture to detect fruits and estimate their calorie and nutritional content. The results of the experiments provide a technical reference for more accurately monitoring an individual's dietary intake by estimating the calorie content of fruits. [ABSTRACT FROM AUTHOR]

The study aims to assess the impact of modified atmosphere packaging (MAP) on the oxidation status of five types of analogue meat products, crucial for extending shelf life and maintaining quality, and seeks to optimize packaging strategies to mitigate oxidation and provide possible solutions for enhancing the overall quality of analogue meat products. Gas ratios in MAP, as well as thiobarbituric acid reactive substances (TBARS), free fatty acids (FFA), total polyphenol content, and antioxidant capacity were assessed through four different assays (2,2-diphenyl-1-picryl-hydrazyl: DPPH, Azino-Bis (3-Ethylbenzothiazoline-6-Sulfonic Acid): ABTS, Ferric Reducing Antioxidant Power: FRAP, Cupric reducing antioxidant capacity: CUPRAC) for analogue meat products (steak, noodles, filet, burger, and mince) on the last day of their shelf life. O
2 ratios in the MAP for all the products did not differ significantly (p > 0.05), but CO2 concentrations significantly differed (p > 0.05) in the MAP of the evaluated products. The minced product exhibited higher oxidative stability with the lowest TBARS (3.20 mg MDA·kg−1 ) and FFA (1.12% total fat as oleic acid), along with a high antioxidant capacity (DPPH: 32.26, ABTS: 4.49% inhibition, CUPRAC: 11.48 Trolox mmol/kg). The filet product was more susceptible to the oxidation process, as evidenced by the significantly (p > 0.05) higher TBARS value (9.71 mg MDA·kg−1 ), lower polyphenol content (1.01 mg gallic acid/g), and antioxidant capacity (FRAP: 4.75 mmol/g, CPRAC: 5.57 Trolox mmol/kg).

Infection of ruminants such as cattle with Mycobacterium avium subsp. paratuberculosis (MAP) causes Johne's disease, a disease characterized by chronic inflammation of the small intestine and diarrhoea. Infection with MAP is acquired via the faecal-to-oral route and the pathogen initially invades the epithelial lining of the small intestine. In this study we used an in vitro 3D mouse enteroid model to determine the influence of M cells in infection of the gut epithelia by MAP, in comparison with another bacterial intestinal pathogen of veterinary importance, Salmonella enterica serovar Typhimurium. The differentiation of M cells in the enteroid cultures was induced by stimulation with the cytokine receptor activator of nuclear factor-βB ligand (RANKL), and the effects on MAP and Salmonella uptake and intracellular survival were determined. The presence of M cells in the cultures correlated with increased uptake and intracellular survival of Salmonella, but had no effect on MAP. Interestingly neither pathogen was observed to preferentially accumulate within GP2- positive M cells. [ABSTRACT FROM AUTHOR]

Lopsp-operations are operations on maps that are applied locally and are guaranteed to preserve all the orientation-preserving symmetries of maps. Well-known examples of such operations are dual, ambo, truncation, and leapfrog. They are described by plane 3-coloured triangulations with specific properties. We developed and implemented a program that can generate all lopspoperations of a given size by reducing the problem of generating lopsp-operations to generating all plane quadrangulations that are not necessarily simple. We extended the program plantri to generate these quadrangulations. [ABSTRACT FROM AUTHOR]

The sampling method for this study is purposive sampling and involves five keropok lekor operators around Selangor. The ingredients used in making keropok lekor are salt, fish filling (fringescale sardine), baking powder, monosodium glutamate (MSG), margarine, and sweet potato flour. Through this study, it was found that the main source of sodium in keropok lekor is salt. For keropok lekor packaging, all keropok lekor operators use the same packaging method, which is vacuum packaging. In addition, the majority of keropok lekor operators (80%) have been introduced to Modified Atmosphere Packaging (MAP). The results of the study show that the average sodium content in keropok lekor is 372.11mg/100g and is categorized as medium-level sodium. Although the majority of keropok lekor operators have been introduced to MAP packaging, further research needs to be conducted to find out whether keropok lekor operators have renewed their packaging methods or vice versa. In conclusion, based on the findings, the content of sodium in the manufacturing of keropok lekor in Selangor is still under control. The results of this study can be used to help the government monitor the sodium content found in keropok lekor around Selangor. [ABSTRACT FROM AUTHOR]

The physiological changes in cut flowers after harvest accelerates their senescence process and greatly affects the quality of cut flowers. Thus the preservation technology is a key factor in limiting the development of the cut-flower industry. The objective of the present study was to explore a new method of preserving cut roses to reduce post-harvest storage and transportation losses. Cut roses were packaged in polyethylene (PE) bags of 40 × 110 cm, with 0, 2, 6, 20, and 30 microperforations of 600 μm at 4°C. The adjustment of the number of microperforations allowed the control of gas concentrations inside the packaging, and those with 20 microperforations permitted the best quality characteristics at 4°C. The findings revealed variations in the gas environment within modified atmosphere packaging (MAP) with different numbers of micropores, which exerted diverse effects on the preservation of cut rose flowers. The MAP with 20 micropores demonstrated the most effective preservation outcome. It not only effectively maintains the antioxidant capacity, the vitality of POD, SOD, and anti-superoxide anion in cut roses but also inhibits the accumulation of H
2 O2 content. Additionally, it effectively maintained the storage quality by inhibiting the respiration rate, ethylene production rate, and decay rate in cut roses. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Although the usefulness of lymphaticovenous anasotmosis (LVA) for lymphedema has been reported, it is difficult to determine where the LVA is to be performed, especially for inexperienced surgeons. This study aimed to establish a map of the LVA site. A total of 105 limbs from 64 patients who underwent lower limb LVA were retrospectively reviewed. Multi-lymphosome indocyanine green (ICG) lymphography (in 35 patients) and lymphatic ultrasound (in all patients) were performed preoperatively and the incision site was determined where dilated lymph vessels and appropriate veins were located in close proximity. The LVA location was identified using a post-operative photograph. Additionally, the degree of lymphatic degeneration at the LVA site was recorded based on the normal, ectasis, contraction, and sclerosis type (NECST) classification. A total of 206 skin incisions were analyzed. Among them, 161 (75.9%) were medial and 45 (21.2%) were lateral. Among the 85 sites on the calf, 52 (61.2%) were medial and 33 (38.8%) were lateral. Among the 117 sites on the thigh, 106 (90.6%) were medial and 11 (9.4%) were lateral. As the severity of lymphedema progressed, the probability of performing LVA on the lateral calf increased. Among the 202 locations where LVA was performed on the thigh and lower leg, ectasis type was found in 164 sites (81.2%). We established an LVA map of the legs based on multi-lymphosome ICG lymphography and lymphatic ultrasound data. Using this LVA map, surgeons can easily predict the location of lymph vessels, thereby improving the success rate of LVA. [ABSTRACT FROM AUTHOR]

Originating from Leipzig and active in Vienna, the printmaker and painter Donat Hübschmann (†1583) had clients from Hungary who were close to the joint Hungarian and Bohemian royal and imperial court in Vienna of the composite Habsburg Monarchy, to which the Kingdom of Hungary belonged. Miklós Oláh (Nicolaus Olahus), humanist prelate and Archbishop of Esztergom, and head of the Hungarian Court Chancellery based in Vienna, commissioned him to make a copy of his etched portrait. János Zsámboky (Johannes Sambucus), who entered court service as a humanist, ordered two works from him. In 1564–65 Zsámboky had an illustrated broadsheet made to commemorate the coronation in Pozsony (now Bratislava, Slovakia) as King of Hungary of Archduke Maximilian II of Habsburg in 1563, which was decorated with a woodcut by Donat Hübschmann: a veduta of Pozsony. Further, in 1566 he assigned Donat Hübschmann to produce a copy of the earliest surviving printed map of Hungary (Lazarus secretarius, Tabula Hungariae , 1528). Other Hungarian-related works can be found among the master's prints, such as a woodcut portrait of Hans Francolin the Younger, Hungarian Herald of Ferdinand I. It is likely that Donat Hübschmann was also responsible for the painted decoration on five letters patent, which were commissioned by Hungarian noblemen and issued by the Hungarian Court Chancellery in Vienna. In every case, the miniature coats of arms were signed with the monogram "DH". The calligraphic decoration of these can be attributed to the noted calligrapher György (George) Bocskay and his workshop. [ABSTRACT FROM AUTHOR]

Purpose: To identify a radiological map of laryngeal subsites whose involvement by the tumor could predict patients' functional outcomes after open partial horizontal laryngectomy (OPHL). Methods: The present retrospective analysis concerned 96 patients with glottic squamous cell carcinoma, who were radiologically staged with contrast-enhanced neck CT scans before undergoing supracricoid or supratracheal laryngectomy. A radiological map of patients' functional risk was developed by considering the distribution of functional outcomes in relation to the laryngeal subsites involved. The functional outcomes considered were: (i) decannulation at discharge; (ii) time to removal of the nasogastric feeding tube (NFT); (iii) postoperative complication rate; and (iv) length of hospital stay. Results: Involvement of the anterior supraglottis was related to a longer need for NFT, and a longer hospital stay (p = 0.003, and p = 0.003, respectively). Involvement of the posterior glottis negatively affected the time to decannulation, and the likelihood of postoperative complications (p = 0.000, and p = 0.002, respectively). Conclusions: Anterior glottic small tumors (without significant subglottic and/or supraglottic extension) are related to the best functional outcomes after OPHL, since the suprahyoid epiglottis and both the arytenoids are likely to be spared.

Climate change is increasing the frequency and intensity of extreme precipitation events, raising the risk of urban flood disasters. This study uses a crowd‐sourced municipal call database to characterize the spatial distribution of flood risk in Detroit, MI. Call data including dates and addresses were obtained from the City of Detroit Department of Public Works for 2021. Calls were mapped and aggregated to census tract counts and merged with neighborhood‐level data. Associations of predictors with flood calls were tested using spatial regression models. Flooding calls were located throughout the city but were concentrated in specific areas. Multivariate models of census tract level call counts indicated that increased poverty and Black, immigrant, and older residents were positively associated with flood calls, while increased elevation was associated with protective effects. Longer distances from waste water interceptors were associated with higher risk for calls. Crowd‐sourced flood hotline call data can be used for effective spatial flood risk assessment. Though flooding occurs throughout the city of Detroit, infrastructural, neighborhood, and household factors influence flooding extent. Limitations included the self‐reported nature of calls. Future modeling efforts might include input from local stakeholders to improve spatial risk assessment. [ABSTRACT FROM AUTHOR]

Natural background gamma rays and their effects on human health are essential components of both radiation protection and public concern. In the frame of these aspects, the mapping of the natural gamma dose rate values of the Province of Asti is given. The Asti Fire Brigade Command approved a project relating to the mapping of gamma radiation from the natural background in the territory of Asti. The project engaged both the Nuclear, Biological, Chemical, and Radiological (NBCR) and Topography Applied to Rescue (TAS) components of the Asti Command. Skilled personnel, comprising level 1 TAS operators for data collection and level 2 TAS operators for cartographic analysis, were deployed across the six working days. The methodology involved the use of two digital handheld radiation G-M detectors, in conjunction with a portable GPS unit, including the Global Mapper software. One of the significant findings of this study is the observation that the natural gamma dose rate levels were 201.25% higher in the streets of the city center compared to other areas, predominantly because the building materials in these locations contain a higher amount of natural radionuclides. The results indicated that the level of natural gamma dose rates in the studied region is close to the global average value. [ABSTRACT FROM AUTHOR]
