Effects of Multimodal Analgesia Combined with Comfort Management on Pain and Stress Indexes in Patients with Orthopedic Trauma after Intervention: A Retrospective Study.

This study aims to assess the impact of combining multimodal analgesia with comfort care on pain levels, stress, negative emotions, and quality of life in individuals recovering from traumatic fractures. This retrospective study analyzed clinical data from traumatic fracture patients who underwent emergency operations at our hospital between June 2022 and February 2024. Patients were divided into two groups based on their postoperative pain management: the control group, which received standard measures, and the exposure group, which received a combination of multimodal analgesia and comfort-based care. We compared these groups for pain intensity (baseline and activity Visual Analog Scale (VAS) scores), serum stress biomarkers (norepinephrine, adrenaline, cortisol), emotional distress (self-rating depression scale (SDS), and the self-rating anxiety scale (SAS)), and overall quality of life (Comprehensive Quality of Life Assessment Questionnaire (GQOLI-74) score). Overall, this study evaluated differences in postoperative complications between the two pain management approaches. In this study, we included 101 participants, 41 in the exposed group and 60 in the control group. Before the intervention, baseline characteristics were similar between the two groups (p > 0.05). However, one week after the intervention, the resting and active VAS scores were significantly reduced in the exposed group than in the control group (p < 0.05). Furthermore, one week after the intervention, the exposed group had lower levels of serum sodium, epinephrine, cortisol, stress, and anxiety, as well as higher physical and mental health scores on the GQOLI-74 scale. During the intervention period, there was no significant difference in postoperative complications between the two groups (p > 0.05). Combining multi-mode analgesia with comfort management for patients with traumatic fractures significantly reduces postoperative pain and stress levels. Additionally, this approach can effectively enhance patients' negative emotions and improve their quality of life. This approach holds significant promise for practical use in clinical settings.

An Overview of Software Sensor Applications in Biosystem Monitoring and Control

This review highlights the critical role of software sensors in advancing biosystem monitoring and control by addressing the unique challenges biological systems pose. Biosystems—from cellular interactions to ecological dynamics—are characterized by intrinsic nonlinearity, temporal variability, and uncertainty, posing significant challenges for traditional monitoring approaches. A critical challenge highlighted is that what is typically measurable may not align with what needs to be monitored. Software sensors offer a transformative approach by integrating hardware sensor data with advanced computational models, enabling the indirect estimation of hard-to-measure variables, such as stress indicators, health metrics in animals and humans, and key soil properties. This article outlines advancements in sensor technologies and their integration into model-based monitoring and control systems, leveraging the capabilities of Internet of Things (IoT) devices, wearables, remote sensing, and smart sensors. It provides an overview of common methodologies for designing software sensors, focusing on the modelling process. The discussion contrasts hypothetico-deductive (mechanistic) models with inductive (data-driven) models, illustrating the trade-offs between model accuracy and interpretability. Specific case studies are presented, showcasing software sensor applications such as the use of a Kalman filter in greenhouse control, the remote detection of soil organic matter, and sound recognition algorithms for the early detection of respiratory infections in animals. Key challenges in designing software sensors, including the complexity of biological systems, inherent temporal and individual variabilities, and the trade-offs between model simplicity and predictive performance, are also discussed. This review emphasizes the potential of software sensors to enhance decision-making and promote sustainability in agriculture, healthcare, and environmental monitoring.

The Value of Refined Nursing Management for Surgical Efficiency, Postoperative Recovery, and Stress Response in Laparoscopic General Surgery.

The study aimed to explore the impact of refined nursing management in the operating room on surgical efficiency, postoperative recovery, and stress responses in patients undergoing laparoscopic general surgery. A retrospective analysis was conducted on 100 patients who underwent laparoscopic surgery at Zhongnan Hospital of Wuhan University between March 2023 and March 2024. The control group comprised 48 cases receiving conventional operating room nursing, while the observation group comprised 52 cases receiving refined nursing management in the operating room in addition to the conventional care. Comparisons were conducted between the two groups regarding surgical efficiency, postoperative recovery, postoperative stress indicators, psychological status before and after nursing, overall treatment comfort, perioperative complications, and nursing satisfaction. The observation group showed statistically significant improvements in surgical efficiency, postoperative recovery, and stress indicators compared to the control group. After the intervention, the Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) scores of both groups significantly decreased compared to pre-nursing levels (p < 0.05), while such decrease was notably higher in the observation group (p < 0.05). Patients in the observation group reported significantly higher post-nursing comfort levels (p < 0.05) and exhibited significantly fewer perioperative complications (p < 0.05) compared to the control group. Furthermore, the nurses indicated significantly higher satisfaction with patient care in the observation group (p < 0.05). Implementing refined nursing in the operating room for laparoscopic general surgery can facilitate the recovery of gastrointestinal function, reduce postoperative recovery time, prevent complications, improve patients' psychological state, and enhance their quality of life.

Statistical analysis of predictors of effectiveness of complex physiotherapeutic treatment in patients with involutional skin changes

BACKGROUND: Analysis of predictors of the effectiveness of various treatment regimens for diseases, as well as the correction of involutionary processes in the human body, is increasingly becoming a standard in scientific medical research. The technology for identifying them traditionally includes the use of correlation and regression analysis, as well as the principles of correlation adaptometry, which makes it possible to approach the solution of this problem from the position of system analysis. AIM: Analysis of predictors of the effectiveness of correction of involutive skin changes in middle-aged and older women with metabolic syndrome using various therapeutic regimens, including hyaluronic acid laser phoresis and the use of transcranial magnetic therapy in combination with oxygen barotherapy. MATERIALS AND METHODS: The study was carried out with the participation of 60 patients from middle and older age with involutional changes in the skin against the background of metabolic syndrome. All patients were divided into 2 groups using simple fixed randomization. The first group (comparison, 30 patients) received laser phoresis of hyaluronic acid in the form of a 1.5% sodium hyaluronate gel using a laser and laser-vacuum therapy device LAZMIK. Patients of the second group (main group, 30 patients) were prescribed combined physiotherapy. For transcranial magnetic therapy, the Amo-Atos device with the Headband attachment was used, and oxygen barotherapy was carried out in single pressure chambers of the Oka-MT or Irtysh-Shch1 type under a pressure of 2 atm for 1 hour. RESULTS: It was found that in the initial state, the quality of life of patients with involutional changes in the skin against the background of metabolic skin syndrome was largely determined by the presence of pathological correlation galaxies that integrate changes in the condition of the skin, metabolic disorders, indicators of oxidative stress and microhemodynamics, and the activity of proinflammatory cytokines. At the same time, the leading role in the deterioration of the quality of life belonged to the age of the patients, the insulin resistance index, transepidermal water loss and microcirculation indicator. However, predictors of effectiveness varied across different treatment regimens. With laser phoresis of hyaluronic acid, its effectiveness increases in younger women with minimal involutional manifestations of skin aging, tested for the condition of the skin, while combined physiotherapy is also most effective in women with a low average age limit, with minimal manifestations of metabolic syndrome and inflammatory processes, as well as against the background of high activity values of one of the enzymes of antioxidant protection ― superoxide dismutase. CONCLUSION: The results obtained convincingly prove the effectiveness of combination therapy in correcting involutive skin changes in middle-aged and older women due to metabolic syndrome, which is comparable in a number of parameters to the effectiveness of hyaluronic acid laser phoresis. At the same time, predictors of effectiveness depend on the characteristics of the mechanisms of therapeutic action of the treatment regimens used, which allows for a more correct approach to the choice of personalized treatment methods.

Ameliorating arsenic and PVC microplastic stress in barley (Hordeum vulgare L.) using copper oxide nanoparticles: an environmental bioremediation approach

The present study investigates the impact of varying concentrations of PVC microplastics (PVC–MPs) – specifically 0 (no PVC–MPs), 2, and 4 mg L− 1 –alongside different arsenic (As) levels of 0 (no As), 150, and 300 mg kg− 1 in the soil, with the concurrent application of copper oxide–nanoparticles (CuO–NPs) at 0 (no CuO –NPs), 25 and 50 µg mL− 1 to barley (Hordeum vulgare L.) plants. This research primarily aims to assess plant growth and biomass, photosynthetic pigments and gas exchange characteristics, oxidative stress indicators, as well as the response of various antioxidants (both enzymatic and non-enzymatic) and their relevant genes expression, proline metabolism, the AsA–GSH cycle, and cellular fractionation within the plants. The findings showed that increased levels of PVC–MPs and As stress in the soil significantly reduced plant growth and biomass, photosynthetic pigments, and gas exchange characteristics. Additionally, PVC–MPs and As stress increased oxidative stress in the roots and shoots, as evidenced by elevated levels of malondialdehyde (MDA), hydrogen peroxide (H2O2), and electrolyte leakage (EL), which in turn stimulated the production of various enzymatic and non-enzymatic antioxidants, gene expression, and sugar content. Furthermore, a notable increase in proline metabolism, the AsA–GSH cycle, and cellular pigmentation was observed. Conversely, the application of CuO–NPs resulted in a substantial improvement in plant growth and biomass, gas exchange characteristics, and the activity of enzymatic and non-enzymatic antioxidants, along with a reduction in oxidative stress. Additionally, CuO–NPs enhanced cellular fractionation while decreasing proline metabolism and the AsA-GSH cycle in H. vulgare plants. These outcomes provide new insights into sustainable agricultural practices and offer significant potential in addressing the critical challenges of heavy metal contamination in agricultural soils.

Association between systemic zinc and oxidative stress levels and periodontal inflamed surface area.

Zinc is a structural component of some enzymes. The aim of this study was to evaluate the potential associations between serum zinc and oxidative stress levels and periodontal inflamed surface area (PISA). This study included 90 patients divided into three groups: a periodontitis group (P; n = 30), a gingivitis group (G; n = 30), and a periodontal health group (PH; n = 30). Periodontal parameters were recorded and PISA values were calculated. Serum total antioxidant status (TAS), total oxidant status (TOS), and zinc levels were examined biochemically. Oxidative stress index (OSI) levels were calculated. All clinical periodontal parameters, periodontal epithelium surface area, and PISA values were lower in the PH group than the P and G groups (p < 0.05). Serum zinc and TAS values were higher in the PH group than the P and G groups (p < 0.05). Serum TOS and OSI values were lower in the PH group than the G and P groups (p < 0.05). Serum OSI levels were lower in the G group than the P group (p < 0.05). PISA was associated with serum zinc (β = -28.96, 95% CI = (-38.95, -18.98), p < 0.001) and OSI (β = 89.84, 95% CI = (20.63, 159.05), p = 0.011) levels in the multivariate generalized linear model. PISA values were associated with decreasing serum zinc and TAS and increased TOS and OSI levels. Zinc deficiency can be associated with the severity of periodontal disease and higher oxidative stress levels.

Mapping of quantitative trait loci (QTL) in Brassica napus L. for tolerance to water stress.

Brassica napus L. plants are sensitive to water stress conditions throughout their life cycle from seed germination to seed setting. This study aims at identifying quantitative trait loci (QTL) linked to B. napus tolerance to water stress mimicked by applications of 10% polyethylene glycol-6000 (PEG-6000). Two doubled haploid populations, each consisting of 150 genotypes, were used for this research. Plants at the two true leaf stage of development were grown in the absence (control) or presence (stress) of PEG-6000 under controlled environmental conditions for 48h, and the drought stress index was calculated for each genotype. All genotypes, along with their parents, were genotyped using the Brassica Infinium 90K SNP BeadChip Array. Inclusive composite interval mapping was used to identify QTL. Six QTL and 12 putative QTL associated with water stress tolerance were identified across six chromosomes (A2, A3, A4, A9, C3, and C7). Collectively, 2154 candidate genes for water stress tolerance were identified for all the identified QTL. Among them, 213 genes were identified as being directly associated with water stress (imposed by PEG-6000) tolerance based on nine functional annotations. These results can be incorporated into future breeding initiatives to select plant material with the ability to cope effectively with water stress.

Impact of zinc oxide nanoparticles on the behavior and stress indicators of African catfish (Clarias gariepinus) exposed to heat stress

This study was designed to assess the role of nano-zinc oxide in mitigating the deleterious effects of heat stress in African catfish (Clarias gariepinus) by evaluating parameters such as aggressive behavior (biting frequency and chasing duration), hematological indicators, and stress-related biochemical markers. A total of 96 catfish were divided into four distinct groups (24 fish/group): The first group (CON) served as the control group, receiving a diet free of nano-zinc oxide. The second group (HS) was exposed to heat stress at 35 °C ± 1 °C. The third group (ZN) was fed a diet containing nano-zinc oxide at 30 mg/kg of the diet, and the fourth group (ZHN) was exposed to heat stress (35 °C ± 1 °C) and fed a diet containing nano-zinc oxide at 30 mg/kg of the diet. The results clarified that the aggressive behavior and cortisol levels were significantly higher (P < 0.05) in the HS group compared to the CON and ZHN groups. Additionally, the level of acetylcholinesterase (AChE) was significantly lower (P < 0.05) in the HS group compared to the CON and ZHN groups. Meanwhile, a significant (P < 0.05) decrease in red blood cells, hemoglobin, packed cell volume, white blood cells, alkaline phosphatase, and lymphocytes, was observed in fish belonging to the HS group, while the levels of alanine aminotransferase, aspartate aminotransferase, neutrophils, and monocytes showed a significant increase (P < 0.05). Supplementation with nano-zinc oxide significantly recovered most hematological and biochemical parameters. In conclusion, nano-zinc oxide contributed significantly to the regulation of the negative impacts of heat stress on fish by reducing aggressive behavior and cortisol levels. Additionally, it improved the levels of AChE and certain hematological and biochemical parameters.

Phytotoxicity Stress Induced by Allelochemicals from Foliar Spray of Sida cordifolia Methanol Leaf Extract on Ageratum conyzoides and Oryza sativa

Allelochemicals are key inhibitors that induce chemical stress in plants. Their mechanisms as agents of oxidative stress are not well understood. A field study was conducted to evaluate herbicidal potential of Sida cordifolia methanol leaf extract (SCLE) on Ageratum conyzoides and Oryza sativa (weedy rice). SCLE concentrations of 0, 3, 6 and 9 g L-1 were prepared and sprayed twice at 7 days interval. The results showed that the SCLE significantly (p&lt;0.05) affected growth attributes, chlorophyll pigments, and proline, and catalase, superoxide dismutase and peroxidase enzyme activities in a concentration-dependent pattern. It was found that high concentrations of SCLE induced greater phytotoxicity against A. conyzoides compared to O. sativa. SCLE spraying stimulated production of reactive oxygen species, boosting their ability to cause damage and inhibit growth. The allelochemicals in the extract stimulated an increased in the level of proline, which is an indicator of oxidative stress. Understanding the physiological and biochemical responses to Sida extract can improve our knowledge on allelochemical target sites and help us to explicate the mechanisms of action of such compounds.

Physiology, gene expression, and behavior as potential indicators of oxidative stress in piglets

The goal of the current study was to develop a pig model to investigate oxidative stress with a low negative impact on piglet welfare. Four independent trials (A, B, C, and D) were performed using a single intraperitoneal shot of lipopolysaccharide (LPS) as an immune challenge, aiming to assess the minimal LPS dose for piglets of different age to trigger a measurable acute oxidative stress response in healthy animals. In trial A, piglets received an LPS dose of 25 µg/KgBW at 41 days post-weaning (p.w.). In trial B, piglets received 25 µg/KgBW of LPS at 28 days p.w., in trials C And D, piglets were injected with 50 µg/KgBW of LPS at 21 days p.w., respectively. Piglets were randomly allocated either to the T1) Control group with saline solution (Ctrl), or T2) LPS challenge (LPS). The oxidative stress response was measured through the enzymatic activity of glutathione peroxidase (GPx), glutathione-S-transferase (GST), superoxide dismutase (SOD), and catalase (CAT), in both plasma and intestinal tissues. Intestinal gene expression of oxidative stress and inflammatory markers was assessed. Discomfort behaviors (panting, prostration, trembling, and vomits) were also recorded. Plasmatic and intestinal oxidative stress response was inconsistent across the four trials even when the dose and pig age were similar, possibly due to individual variability. Relative gene expression differences of anti-inflammatory cytokines (IL10), oxidation precursor (iNOS), and antioxidant markers (GPx4, MnSOD, and CAT) were detected between Ctrl and LPS treatment (P < 0.05) when assessed. Behavioral observations were sensitive to the LPS dose relative to Ctrl (P < 0.05) in all four trials. These results suggest that behavioral observations can be used as a non-invasive methodology to detect the presence of oxidative stress in pigs in challenging conditions. Behavioral observations were more sensitive than other indicators (i.e., biomarkers and gene expression) in the current study. However, a sensitivity scale system needs to be developed to qualify and rank the impact of oxidative stress in pigs.

Trans-chalcone ameliorates CCl4-induced acute liver injury by suppressing endoplasmic reticulum stress, oxidative stress and inflammation

BackgroundAcute liver injury serves as a crucial marker for detecting liver damage due to toxic, viral, metabolic, and autoimmune exposures. Due to the response to adverse external stimuli and various cellular homeostasis, Endoplasmic reticulum stress (ERS), Oxidative stress, and Inflammation have great potential for treating liver injury. Trans-chalcones (TC) is a polyphenolic compound derived from a natural plant with anti-oxidative and anti-inflammatory abilities. Here, TC was aimed to attenuate liver injury by triggering ER stress, oxidative stress, inflammation, and apoptosis. A single dose of carbon tetrachloride (CCl4) 1 mL/kg was administered intraperitoneally into C57BL6 mice to construct an in vivo NAFLD model, whereas AML12 cells were treated with lipopolysaccharides (LPS) to construct an in vitro NAFLD model. The mice used in the experiment were randomly assigned to two groups: a 12-hour set and a 24-hour set. Forty-nine mice were randomly divided into seven groups, the control group (Group I), TC group (Group II) 10 mg/kg TC, negative control group (Group III) CCl4, TC + CCl4 groups (Groups IV−VI), mice were subcutaneously treated with (5, 10, and 20) mg/kg of TC for three consecutive days before the CCl4 injection and the positive control group (Group VII) received 10 mg/kg Silymarin. After the experiment, serum transaminase, liver histological pathology, hepatic expression levels ERS, oxidative stress, and inflammation-related markers were assessed. TC pre-treatment significantly alleviates the expression of ER stress, oxidative stress, inflammatory cytokines, and apoptosis in both in vivo and in vitro models of liver injury. TC treatment significantly reduced serum transaminase levels (ALT and AST), and improved liver histopathological scores. TC administration also led to a reduction in MDA levels and the suppression of ROS generated by CCl4 in hepatic tissue, which contributed to an increase in GSH levels. The protective effect of TC on the liver injury mouse model was achieved by inhibiting hepatocyte apoptosis. Moreover, TC pre-treatment dramatically decreased the protein levels of ER stress indicators such as CHOP, Bip, Ero-Lα, IRE1α, PERK, Calnexin, and PDI when compared to the CCl4-only treated group. TC exerts hepatoprotective effects against CCl4-induced acute liver injuries in mice by modulating ERS, oxidative stress, and inflammation. These results suggest that TC pre-treatment at a dose of (20 mg/kg BW) was as effective as silymarin (10 mg/kg) in preventing CCl4-induced acute liver injury. Further investigations are necessary to elucidate the precise molecular mechanisms underlying the hepatoprotective effects of TC and to explore its therapeutic potential in clinical trials.

Sirt1/Nrf2/TNFα; TLR4/Myd88/NF-κB signaling pathways are involved in mediating hepatoprotective effect of bupropion in rat model of myocardial infarction

Background The aim of the current study is to identify the possible protective effect of bupropion (BUP) on liver injury in rat model of myocardial infarction (MI). BUP was administered in the presence and absence of MI. Materials and methods Thirty-two Wistar adult male rats were randomly arranged into four groups: control, BUP (30 mg/kg/day, intraperitoneal) for 28 days, isoproterenol (ISO) was injected subcutaneous (85 mg/kg) in the 26th and 27th days and BUP/ISO groups. Cardiac and hepatic enzymes were measured, also Hepatic oxidative stress indicators, as well as inflammatory and apoptotic biomarkers, were evaluated. Cardiac and hepatic histopathological examination and hepatic nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) immunohistochemical study were also detected. Results ISO significantly increased cardiac and hepatic enzymes, hepatic oxidative stress, inflammatory, apoptotic, with a histopathological picture of cardiac and hepatic damage and high hepatic NF-κB immunoexpression were detected. BUP significantly normalized the upraised oxidative, inflammatory, and apoptotic parameters, with an impressive improvement in the histopathological picture and a reduction in hepatic NF-κB immunoexpression. Conclusion BUP protects against liver injury on top of MI in rat model via modulation of Sirtuin type 1 (Sirt1)/Nuclear factor (erythroid-derived 2)-like 2 (Nrf2)/tumor necrosis factor α (TNFα); Toll-like receptor 4 (TLR4)/Hepatic myeloid differentiation primary response 88(Myd88)/NF-κB signaling pathways.

Measurement of stress optical coefficients for GFRP based on terahertz time-domain spectroscopy

Glass Fiber-Reinforced Polymer (GFRP) finds extensive applications in the high-end equipment manufacturing industry owing to its advantages of light weight, high strength, and corrosion resistance. Since the residual stress in GFRP builds up during the curing process and affect its mechanical properties and service life, the characterization of the residual stress in GFRP is crucial. In this study, we establish a theoretical model based on the anisotropic stress-optics law for the orthorhombic crystalline system to describe the terahertz-elasticity of GFRP and calibrate the stress optical coefficients of GFRP. First, the residual stress in GFRP at different curing temperatures are measured by fiber Bragg grating sensors. Then, the refractive index of GFRP with different residual stress are obtained based on transmission-type THz-TDS. Finally, based on the proposed photoelastic model of GFRP, the stress optical coefficients of GFRP are measured by combining the measurement results of residual stress and refractive index. The experimental results show that the refractive index of GFRP decreases with the increase of residual stress; the stress optical coefficients of GFRP are determined as q11 = −5.612 × 10−9 Pa−1, q12 = −2.548 × 10−9 Pa−1, q21 = −1.305 × 10−8 Pa−1, q22 = −1.408 × 10−9 Pa−1. The modeling of terahertz photoelasticity in GFRP and the determination of stress optical coefficients provide a basis for characterizing residual stress in GFRP by THz-TDS.

학교폭력 가해자에 대한 경찰다이버전 정책 기반 다중체계치료 사례연구

Objectives This purpose of the study was conducted to explore the effectiveness of Multisystemic Therapy for school violence perpetrators as part of the police diversion policy. Methods The subject of the study was a 14-year-old male student who was reported to have school violence, which is extortion and intimidation, and was released on the condition of participating MST. In accordance with the multisystemic therapy manual, five key goals were derived by analyzing risk factors for adolescents' problematic behaviors through evaluation of various systems surrounding him. An intervention strategies were established to achieve the core goals(i.e., stop smoking and alcohol, controlled use of SNS, making pro-social friends, stay away from delinquents, promoting positive parenting skills of parents). The essential parts of MST as like the therapy team, the visiting service, and weekly supervision were implemented. In order to measure pre-post changes, Children Behavior Checklist 6-18, the Parenting Stress Index, the Parenting Attitude Test, and the MMPI-A were conducted. The package of scales was implemented at 3 points as pre-time, post-time, and 8 months follow-up. Results First of all, the level of the externalization problem scale of CBCL 6-18, which was at the clinical range at the pre-test, recovered to the level of the normal range in the post-test, and these results were maintained even at the 8 months follow-up. Regarding MMPI-A, the score was lowered by nearly 2 standard deviations in the scale of Pd compared to pre-test. Then, parenting stress decreased and positive parenting attitudes of parents increased. In addition, all the five core goals were achieved. Conclusions The results of this study showed that multisystemic therapy for school violence perpetrator can help decrease adolescents’ problematic behaviors including school violence.

Animal welfare of Lacaune lambs weaned from artificial feeding.

Nowadays, many dairy sheep farms opt for milk replacers after birth. Weaning lambs from milk replacers is expected to be a stressful situation. With the aim of researching this practice on the animal behavior, body weight yields, and sanitary status of Lacaune lambs, 60 healthy animals from the same lambing house were employed. Lambs were housed in a pen and had ad libitum access to forage, compound feed, and milk replacers. During a 4 days preexperimental period in which all the animals were fed with milk replacers, behavior, hematologic parameters, body weight and seric and fecal stress indicators were recorded. Later, an experimental period took place in which 20 lambs remained in the same conditions. Another 20 lambs were kept in a separate pen in the same barn under the same conditions, but the artificial milk feeding was interrupted (weaning). The third 20 lambs were weaned and also rehoused in fattening pens. After 4 days, the variables previously recorded in the three groups during the pre-experimental period were recorded again. Results showed that change of location and change of feed can have different and synergic effects on the behavior of the lambs. Change of feed had not specifically different effect on body weight than change of location. In the other hand, weaning had no significative effects on hematologic parameters and seric and fecal stress indicators. Weaning from artificial milk had significative effects on lambs weight and behavior. More research is needed to improve this ethical aspect in ovine production.

Soluble Urokinase-Type Plasminogen Activator Receptor (suPAR), Growth Differentiation Factor-15 (GDF-15), and Soluble C5b-9 (sC5b-9) Levels Are Significantly Associated with Endothelial Injury Indices in CAR-T Cell Recipients

Endothelial injury indices, such as Endothelial Activation and Stress Index (EASIX), modified EASIX (m-EASIX), and simplified EASIX (s-EASIX) scores, have been previously associated with chimeric antigen receptor-T (CAR-T) cell immunotherapy complications. Soluble urokinase-type plasminogen activator receptor (suPAR), growth differentiation factor-15 (GDF-15), and soluble C5b-9 (sC5b-9) have been described as markers of endothelial injury post-hematopoietic stem cell transplantation. In the current study, we examined whether suPAR, GDF-15, and sC5b-9 levels were associated with endothelial injury indices in adult CAR-T cell recipients. The levels of these markers were measured in patients before CAR-T cell infusion and in healthy individuals with immunoenzymatic methods. We studied 45 CAR-T cell recipients and 20 healthy individuals as the control group. SuPAR, GDF-15, and sC5b-9 levels were significantly higher in the patients’ group compared to the healthy control group (p &lt; 0.001, in all comparisons). SuPAR levels at baseline were associated with the m-EASIX scores calculated at the same time point (p = 0.020), while suPAR and GDF-15 concentrations were correlated with EASIX scores at day 14 post-infusion (p &lt; 0.001 in both comparisons). Moreover, sC5b-9 levels were correlated with the s-EASIX scores at infusion (p = 0.008) and the EASIX scores at day 14 (p = 0.005). In our study, sC5b9, suPAR, and GDF-15 levels were found to reflect endothelial injury in CAR-T cell recipients.

How Does Social Inequality Alter Relationships Between Porous Cranial Lesions and Mortality? Examining the Relationship Between Skeletal Indicators of Stress, Socioeconomic Status, and Survivorship in a Pediatric Autopsy Sample.

In prior exploration of modern and archeological populations, lower SES has been associated with an increased risk of mortality. However, SES is often difficult to ascertain in archeological populations. Thus, explorations of skeletal lesions and their association with mortality may be subject to confounding factors that alter the strength and/or direction of this association. The present study uses data from a modern, documented coronial pediatric dataset to examine the association between porous cranial lesions (PCLs) (cribra orbitalia [CO] and porotic hyperostosis [PH]) and age at death while controlling for SES, as inferred through housing type, with manufactured or apartment housing identified as reflecting individuals from lower SES backgrounds in this context. We include 887 (535 males, 352 females) individuals aged 0.5-20.9 years from New Mexico who died between 2011 and 2022. Kaplan-Meier survival analysis was used to assess survivorship as related to PCLs and SES. Low SES is associated with lower survivorship. CO does not have a significant association with age at death when not controlling for SES; PH alone is associated with older age at death. Disadvantaged individuals with PCLs have significantly reduced survivorship than those with higher SES. The findings of this study demonstrate that low SES results in reduced survivorship, and those with low SES and PCLs have worse survivorship than less disadvantaged individuals with PCLs. Thus, the strong contribution of SES to mortality necessitates the consideration of the sociocultural context as a confounding factor when examining associations between variables of interest (such as lesions) and mortality in both past and present populations.

The Apoptotic, Cytotoxic, and Anti-migration Effects of Sodium Deoxycholate in a Breast Cancer Cell Line and its Modulation on PON1 as a Predictive Risk Marker.

Breast cancer is the most prevalent cancer among women and is usually treated with antineoplastic drugs. The present study examines the influence of sodium deoxycholate on the molecular pathways underlying apoptosis, cytotoxicity, and the modulation of PON1 in the MCF-7 breast cancer cell line. Various doses were administered to test the hypothesis that it could potentially affect cancer cells. The study examined the cytotoxic effect of sodium deoxycholate on MCF-7 cells and human mammary epithelial cells (CRL-4010) using the MTT method to detect its anticancer properties. Subsequently, the efficacy of the active dose on DNA fragmentation and apoptosis was examined using the apoptotic DNA ladder and Western blot methods. Additionally, oxidative stress index and cell migration tests were conducted. Notably, sodium deoxycholate did not cause DNA damage despite demonstrating cytotoxic effects on cells. The study found that sodium deoxycholate increased the levels of several pro-apoptotic proteins, leading to apoptosis. Moreover, it markedly diminishes the activity of paraoxonase and arylesterase of PON1, which are predictive risk markers for cancer. Furthermore, it was found to delay cell migration in a time-dependent manner. These findings suggest that sodium deoxycholate exhibits an antimetastatic effect in breast cancer cells, could be a valuable subject for further cancer research.

Gastrointestinal toxicity following sub-acute exposure of erythrosine in rats: biochemical, oxidative stress, DNA damage and histopathological studies.

Erythrosine, a synthetic food dye, has been controversial due to its potential health risks. This study examines the effect of erythrosine on activity of antioxidative enzymes, oxidative stress indices, DNA damage through comet assay, and histopathological changes on stomach, intestine, and colon over a period of 28 days in rats. Twenty-four rats were randomly divided into four groups (n = 6). The first is the control group and then one each for three doses of erythrosine based on acceptable daily intake (¼ ADI, ½ ADI, and ADI, 0.1 mg/kg body weight). The results revealed that with increasing dosages the activity of catalase decreased in stomach and intestine but in colon, the catalase activity increased. Superoxide dismutase and glutathione-S-transferase activity decreased in dose-dependent manner in all three tissues. While, in stomach and intestine, the acetylcholinesterase activity showed increment in ¼ ADI dose group and then declined in ½ ADI and ADI dose-administered rats. The oxidative stress indicators showed elevated levels of lipid peroxidation, hydrogen peroxide concentration, and lactate dehydrogenase activity suggesting heightened free radical activity and potential oxidative damage. The comet test was used to evaluate DNA damage, revealing substantial damage in the erythrosine administered groups. Histopathological examination showed inflammatory infiltration and other degenerative changes in gastrointestinal tract, highlighting the dye's adverse effects. The research underscores the need for a comprehensive reevaluation of the safety and toxicity of food dyes like erythrosine, especially considering the inconsistencies in existing studies regarding the dye's safety.

Developing a New Method to Rapidly Map Eucalyptus Distribution in Subtropical Regions Using Sentinel-2 Imagery

Eucalyptus plantations with fast growth and short rotation play an important role in improving economic conditions for local farmers and governments. It is necessary to map and update eucalyptus distribution in a timely manner, but to date, there is a lack of suitable approaches for quickly mapping its spatial distribution in a large area. This research aims to develop a uniform procedure to map eucalyptus distribution at a regional scale using the Sentinel-2 imagery on the Google Earth Engine (GEE) platform. Different seasonal Senstinel-2 images were first examined, and key vegetation indices from the selected seasonal images were identified using random forest and Pearson correlation analysis. The selected key vegetation indices were then normalized and summed to produce new indices for mapping eucalyptus distribution based on the calculated best cutoff values using the ROC (Receiver Operating Characteristic) curve. The uniform procedure was tested in both experimental and test sites and then applied to the entire Fujian Province. The results indicated that the best season to distinguish eucalyptus forests from other forest types was winter. The composite indices for eucalyptus–coniferous forest separation (CIEC) and for eucalyptus–broadleaf forest separation (CIEB), which were synthesized from the enhanced vegetation index (EVI), plant senescing reflectance index (PSRI), shortwave infrared water stress index (SIWSI), and MERIS terrestrial chlorophyll index (MTCI), can effectively differentiate eucalyptus from other forest types. The proposed procedure with the best cutoff values (0.58 for CIEC and 1.29 for CIEB) achieved accuracies of above 90% in all study sites. The eucalyptus classification accuracies in Fujian Province, with a producer’s accuracy of 91%, user’s accuracy of 97%, and overall accuracy of 94%, demonstrate the strong robustness and transferability of this proposed procedure. This research provided a new insight into quickly mapping eucalyptus distribution in subtropical regions. However, more research is still needed to explore the robustness and transferability of this proposed method in tropical regions or in other subtropical regions with different environmental conditions.
