A Gram-positive, aerobic, rod-shaped and spore forming bacterium strain designation B190/17, was isolated from an air monitoring sample of a Brazilian immunobiological production facility in 2017. The strain was not identifiable by biochemical methodology VITEK® 2 or by MALDI-TOF MS with VITEK® MS RUO and MALDI Biotyper®. The 16S rRNA gene sequencing showed 98.51% similarity with Bacillus wudalianchiensis FJAT 27215T, 98.28% with ‘Bacillus aerolatus’ CX 253T, 97.96% with Bacillus badius MTCC 1458T, 97.63% with Bacillus xiapuensis FJAT 46582T and 97.21% with Bacillus thermotolerans SGZ8T. Biochemical data showed the strain was alanine arylamidase, Ala-Phe-Pro arylamidase, ELLMAN, leucine arylamidase, phenyalanine arylamidase and tyrosine arylamidase positive. The genomic DNA G+C% content of B190/17 was 41.6 mol%. The phylogenetic, genomic taxonomy and biochemical tests suggested that B190/17 represents a novel species and should be classified as the type strain of a novel Bacillus species. The name Bacillus lumedeirus sp. nov. is proposed. After characterization, B190/17 was added to the MALDI Biotyper® database as Bacillus lumedeirus sp. nov.

Considering the large number of candidates in vaccine testing studies against different pathogens and the amount of time spent in the pre- and clinical trials, there is a pressing need to develop an improved in vivo system to quickly screen vaccine candidates. The model of a polyester-polyurethane sponge implant provides a rapid analysis of the specific stimulus-response, allowing the study of a compartmentalized microenvironment. The sponge implant’s defined measurements were standardized as a compartment to assess the immune response triggered by vaccinal antigen. The LBSap vaccine (composed by Leishmania braziliensis antigens associated with saponin adjuvant) was used in the sponge model to assess the antigen-specific immunological biomarker, including memory generation after initial contact with the antigen. Mice strains (Swiss, BALB/c, and C57BL/6) were previously immunized using LBSap vaccine followed by an antigenic booster performed inside the sponge implant. The sponge implants were assessed after 72 hours, and the immune response pattern was analyzed according to leukocyte immunophenotyping and cytokine production. After LBSap vaccination, the innate immune response of the antigenic booster in the sponge implants demonstrated higher levels in the Ly+ neutrophils and CD11c+ dendritic cells with reduced numbers of F4/80+ macrophages. Moreover, the adaptive immune response in Swiss mice demonstrated a high CD3+CD4+ T-cells frequency consisting of an effector memory component in addition to a cytoxicity response (CD3+CD8+ T-cells), displaying the central memory biomarker. The major cell surface biomarker in the BALB/c mice strain was related to CD3+CD4+ effector memory while the increased CD3+CD8+ effector memory was highlighted in C57/BL6. The cytokine profile was more inflammatory in Swiss mice, with the highest levels of IL-6, TNF, IFN-g, and IL-17, while the same cytokine was observed in in C57BL/6 yet modulated by enhanced IL-10 levels. Similar to Swiss mice, BALB/c mice triggered an inflammatory environment after the antigenic booster in the sponge implant with the increased levels in the ILL-6, TNF, and IFN-g. The results highlighted how genetic background can influence populations involved in the immune response and indicated that it is possible to use this model to optimize and monitor the innate and adaptive immune responses of vaccine candidates. In this sense, these results could guide the choice of the most appropriate experimental model in biomolecule tests, considering that the particularities of each mouse strain influenced the dynamics of the immune response.

Published: October 2024

The metabolomics of Newhall navel oranges with geographical indication (GI) was measured by LC-MS/MS from three areas Ganzhou, Fengjie, and Zigui in China. Orthogonal partial least squares-discriminant analysis was performed for samples classification and important metabolites identification. This approach identified the best markers (i.e. tricarboxylic acid, amino acids, and phenolics) of the geographical origin able to discriminated Fengjie, Ganzhou, and Zigui organge samples. The results showed that peeled-samples from Zigui were richest and those from Fengjie lowest in all of the top ten most important markers. In whole samples, the highest levels of seven important markers occurred in those from Zigui, and the other three important markers appeared the highest levels in those from Ganzhou. According to the variation of the best markers, and the highest value of titratable acidity in those from Zigui, the samples planted in Ganzhou have the best balance between taste and nutrition. This work confirms the approach of metabolomics combined with OPLS-DA is an effective way for origin tracing and overall quality evaluation.

The easiest way to utilise leather waste shavings is normally to produce new fuels from the most contaminated fractions for combustion or gasification. But since these waste contain up to 10% of nitrogen (N), burning it only for the energy recovery would not be rational. On the other hand, the chromium (Cr) content exceeding 5% in half of the waste stream (w/w) is too significant to be applied in agriculture. In this work, 4 acid hydrolysates from leather waste shavings both wet-white free of Cr and wet-blue with Cr were used: 2 with a mixture of acids and supplemented with Cu, Mn, Zn and other 2 as semi-product from collagen extraction using hydrochloric acid. The acid hydrolysates were prepared using a specific combination of acids under controlled conditions, ensuring the maximum release of nitrogen while maintaining the safety and integrity of the process. Additionally wet-green leather waste shavings eg. impregnated with olive extract were used followed by their 2 treatments: amendment with a biochar from “wet white” leather waste shavings and amendment with this biochar incubated with a commercial phosphorus stimulating microbial consortia BactoFos. They were applied as organic nitrogen-based fertilisers in a glasshouse experiment, consisting of 4-5 subsequent harvests every 30 days, under spring-autumn conditions in northern Poland. Ryegrass dry matter and nitrogen plant content were measured across 7 increasing fertiliser doses. Nitrogen utilisation, relative agronomic effectiveness, nitrogen use efficiency, total ryegrass dry matter and nitrogen utilisation breakdown across harvests were calculated. Biochar amended wet-greens provided the highest nitrogen use efficiencies exceeding 100% after 4 months growth (for 20 kg N/ha) and varying from 17% to 37% in particular months. This is backed up by another parameter (relative agronomic effectiveness) that for these materials exceeded 150% for single month and in total around 33%. Biochar amendments significantly increased agronomic parameters for wet-greens and their microbial treatment enhanced them even further. In sustainability aspects, assuming only the industrial partner waste potential, that gives 919,8 t of recycled nitrogen per year, which comes back to the environment in plant biomass. Recycling this type of waste can replace inorganic fertilizers reducing greenhouse gas emissions and carbon footprint.

Published: October 2024

The volatility of global energy markets, particularly electricity prices, plays a crucial role in influencing international economic activities. In the era of big data, machine learning has revolutionized the field of cancer research, particularly in analyzing gene expression data. This study explores the application of machine learning models to the GSE45827 dataset, which contains breast cancer gene expression profiles. With over 54,000 genes and 151 samples categorized into six classes, the dataset presents a high-dimensional challenge that is addressed using dimensionality reduction techniques such as Principal Component Analysis (PCA) and t-distributed Stochastic Neighbor Embedding (t-SNE). The PCA method proved most effective in retaining the critical features of the data in lower dimensions, allowing for clearer visualization and enhanced model performance.The reduced dataset was then classified using the eXtreme Gradient Boosting (XGBoost) model, achieving promising multi-class classification results. The model demonstrated high precision, recall, and F1-scores across several classes, particularly excelling in classes 1, 2, and 5. However, certain classes, such as 0 and 4, exhibited lower recall, highlighting areas for further refinement. The integration of PCA and XGBoost not only improved the interpretability and computational efficiency of the model but also contributed to the accurate identification of breast cancer subtypes, emphasizing the importance of machine learning in cancer diagnosis and treatment.

Published: October 2024

The influence of sericin supplementation and chilling temperatures (4°C and 15°C) on the short-term storage quality and fertility of rabbit semen was assessed over 72 hours of storage. In experiment 1, pooled semen (from five ejaculates) was diluted to a concentration of 50M ml−1, and assigned to control, 0.1% and 0.5% sericin groups, stored at 4 or 15°C. Sperm motility, sperm kinematics, viability, membrane and acrosome integrity were assessed at 0, 24, 48, and 72 hours of storage. The experiment 2 and 3 were conducted to observe effect of sericin on bacterial growth and in vivo fertility. The results of experiment 1 showed that sericin treatment, storage temperature, and storage duration influenced progressive and total motility, as well as sperm kinematics. Similar effects were observed for acrosome integrity, membrane integrity, and sperm viability. The results of experiment 2 indicated the antimicrobial effects of sericin when sperm were stored at 15C for 72 hours. While promising pregnancy outcomes were observed with sericin treated sperm for 72 hours, these results not significantly different. The study conclusively demonstrates that sericin treatment enhances the quality of rabbit semen when stored at lower temperatures for longer durations. Antimicrobial effects of sericin could be a contributing factor to the improved in-vitro and in-vivo fertility of rabbit sperm.

Authors: Aladayleh Khaled Jameel , Aladaileh Mohammad J
Published: October 2024

This study explores integrating Building Information Modeling (BIM) technology into risk management practices for construction projects, aiming to enhance project performance through improved risk identification, assessment, and mitigation. The research employs the Analytical Hierarchy Process (AHP) to prioritize BIM-based strategies across multiple risk management dimensions, including technical, financial, sustainability, and time management. The findings demonstrate that BIM-financial strategies rank most among BIM-driven risk management, followed by sustainability and time. In contrast, Technical, Operation, and maintenance capabilities have the lowest rank. Given the high priority of BIM financial strategies, it has been applied to conduct sensitivity analysis; the sensitivity analysis results demonstrate the dynamic nature of BIM sub-criteria strategy in response to changes in the weight of financial considerations. As financial concerns diminish, the shift towards sustainability, health, safety, and time efficiency underscores the importance of a more balanced approach in BIM strategy prioritization. BIM- risk management improves project outcomes by enabling real-time data-driven decision-making, enhancing stakeholder collaboration, and optimizing resource use, cost control, and sustainability. This research contributes to theoretical and practical advancements in construction risk management, suggesting that BIM can be a transformative tool for optimizing project performance while addressing the complexities and uncertainties inherent in the construction industry.

Thistle (Onopordum acanthium) has been traditionally employed for liver protection, however, we recently identified silibinin, the main bioactive compound of thistle extract, as an in vitro pancreatic lipase inhibitor, which suggested a potential role as anti-obesity agent. This study aimed to assess, in vivo, the efficacy, safety, and effects of silibinin on human lipase. As a secondary objective, we evaluated potential changes on gut microbiota after silibinina treatment. A randomized trial comparing 150mg/silibinin, 300mg/silibinin, and a thistle extract (equivalent to 150 mg/silibinin) with placebo and orlistat/120mg was conducted. Fecal fat excretion, clinical parameters, and microbiota changes were analyzed. Orlistat showed the highest fecal fat excretion, although thistle extract had similar results (p = 0.582). The 150 mg/silibinin group reported the fewest adverse effects. Both silibinin and orlistat reduced plasma triglycerides (p=0.016) and waist circumference (p=0.001). Specific microbiota changes, such as increases in Mycobacteriaceae and Veillonellaceae, were associated with higher fat excretion. Silibinin proved to be safe and effective for obesity, with minimal adverse effects and no significant changes in microbiota diversity. Further studies are needed to explore its microbiota-related benefits.

Published: October 2024

It is crucial to conduct quality control tests to assess the quality and consistency of medicinal plant products before they are used. Products can often be placed on the market without registration, but some countries may require manufacturers to present product labels to authorities before selling them. These labels should confirm the composition of the product, particularly the concentrations of cannabidiol (CBD). The information on the label should provide unambiguous details about the qualitative composition and concentration of primary cannabinoids, such as CBD and THC. However, since there is a lack of regulatory control, it is possible to find inaccurate information on the label.
This study aimed to create and validate a high-performance liquid chromatography method for identifying active compounds (cannabinoids) in CBD oil. The main compounds identified included Cannabidivarin (CBDV), Cannabidiolic Acid (CBD-A), Cannabigerolic Acid (CBG-A), Cannabigerol (CBG), Cannabidiol (CBD), Tetrahydrocannabivarin (THCV), Cannabinol (CBN), ∆9- Tetrahydrocannabinol (d9 -THC) ∆8- Tetrahydrocannabinol (d8-THC), Cannabicyclol (CBL), Cannabichromene (CBC), and Tetrahydrocannabinolic Acid (THCA-A), determined in line with the International Conference on Harmonization's (ICH) guidelines. The method was validated for linearity, accuracy, precision, limit of detection (LOD), and limit of quantitation (LOQ). It was determined to be linear, with a correlation coefficient (R2) ranging from 0.99937 to 0.99973. The LOD and LOQ values calculated from the calibration curve ranged from 0.05 to 0.13 and 0.50 to 0.61 µg/mL, respectively. The method also exhibited acceptable precision, with relative standard deviation values lower than or equal to 2%. The method's accuracy was assessed through recovery percentages and fell within an acceptable range (98.12–102.39%). This study's rigorous methodology and comprehensive findings significantly contribute to cannabinoid analysis.
This validated protocol was used to analyze the cannabinoid concentration levels in 14 CBD oil products in the Republic of North Macedonia. The performance parameters indicate that the developed and validated method is suitable for quantitatively determining cannabinoids in CBD oil. The analysis of 14 CBD oil products revealed no significant derogation regarding the labeling, i.e., they were by the producers' declared variability.

Published: October 2024

The purpose of this paper is to determine the polycyclic aromatic hydrocarbons (PAHs) from medicinal plants and infusions prepared on them, as well as the assessment of the transfer of these contaminants from plants to infusions. The separation of compounds was achieved using microwave extraction for dryed plants and liquid-liquid extraction in the case of infusions. The extracts were cleaned by solid phase extraction, and compounds analysed by gas chromatography coupled with mass spectrometry (GC-MS). The risks related to the consumption of the infusions from the analysed plants were also evaluated by calculating the exposure contribution to the infusion consumption (EDI, ng/Kg.bw/day) and Margins of Exposure (MOEs). The average total content of PAHs varied from 277.22±12.78 to 2466.46±203.45µg/kg in dry plants, and benzo[b]fluoranthene and benzo[a]pyrene are the compounds present in all samples. In the herbal tea infusions, the average total PAHs content varied between 612.55±46.12ng/L and 2292.2±140.24ng/L. Statistical analysis showed that only BabF shows a significant strong correlation between the content of individual PAHs in plants and their infusions, while BaP, 4PAHs and HMW-compounds showed weak correlations. Average transfer rates of ∑16PAHs from plants to infusions varied from 7.25 to 32.86%. The MOEs of BaP and 4PAHs in herbal tea infusions with the highest PAH content confirmed that the consumption of medicinal teas presents a low risk to contamination with PAHs.
Signal Processing for High-Frequency Flow Rate Determination: An Analytical Soft Sensor Using Two Pressure Signals
Authors: Brumand-Poor Faras , Kotte Tim , Pasquini Enrico , Schmitz Katharina
Published: October 2024

Accurate knowledge of flow rates is essential for hydraulic systems, as it allows for calculating hydraulic power when combined with pressure measurements. This data is helpful in applications such as predictive maintenance. However, most flow rate sensors in fluid power systems operate invasively, disrupting the flow and producing inaccurate results, particularly for transient flow conditions. A common approach is calculating the flow rate using the pressure difference along a pipeline based on the Hagen-Poiseuille law. However, this method is limited to laminar, steady, incompressible flow. This paper presents a novel soft sensor with an analytical model for transient, compressible pipe flow based on two pressure signals, thus no actual volumetric flow rate sensor is required. The model is derived by solving the fundamental fluid equations in the Laplace domain and converting the solution back to the time domain to obtain a physical representation. The relationship between the pressure difference signal and flow rate is derived using the four-pole theorem. The resulting analytical solution, including a convolution integral with a weighting function, shows high accuracy for transient and steady flows. This new equation enables the development of a soft sensor capable of non-invasive flow rate measurements for various pipe flow conditions.
Social Filter Theory——A Sleeping Beauty of Regional Innovation Theories
Authors: Ren Jianhui , Lai Linlin , Pei Binjie , Zhan Wenyu
Published: October 2024

As a branch of regional innovation theories, social filter theory fundamentally reveals the reasons for the geography of innovation in different countries and regions. However, compared with some other regional innovation theories, social filter theory has been as silent as a sleeping beauty and hasn’t been fully developed. For enriching and developing social filter theory, this article systematically traces the source and comments on four aspects: the concept of social filter, the construction and measurement of indicators of social filter, the mechanism and empirical re-search of social filter affecting regional innovation and innovation transformation. Until recently regional innovation theories primarily focused on the superficial description of the phenomenon of innovation, but lack of attention to the local social filter condition of innovation generation and innovation transformation, which are the pre-condition of constructing mature innovation system. Therefore, additional efforts are still required to fill the current knowledge gap from the recom-mended directions in the article.
Endothelial Protection and Improved Micro- and Macrocirculation with Hemoadsorption in Critically Ill Patients
Authors: Papp Marton , Ince Can , Bakker Jan , Molnar Zsolt
Published: October 2024

A dysregulated immune response is associated with the excessive release of cytokines that can lead to systemic vasoplegia and vasoplegic shock with the development of multiorgan failure that is associated with an increased risk of dying. Under physiological circumstances, the endothelium and the glycocalyx are responsible for maintaining vascular tone, capillary permeability, hemostasis, and controlling inflammation. In hyperinflammation, the endothelium and glycocalyx become damaged due to the excessive production of certain toxic proteins, along with an overwhelming release of cytokines. It has been shown in both in vitro animal experiments and also in humans that extracorporeal hemoadsorption can reduce circulating levels of cytokines and may also remove toxic proteins that directly take part in endothelium and glycocalyx damage. The current review aims to summarize current knowledge and to put recent findings into context, and introduce the hypothesis of “endothelial protection with hemoadsorption” in critically ill patients.

Published: October 2024

The circular economy with compost fertilization is included in the sustainable orchard paradigm, creating a holistic production ecosystem. Modern orchards are mostly intensive and super-intensive, requiring different rootstocks. This research presents the response to compost fertilization of two specific pear rootstocks (quince ‘CTS 212’ and ‘Farold® 40’) and own-rooted trees, analyzing six resistant cultivars in a circular production system. The dynamic of nitrogen and carbon content in leaves, soil respiration coefficient, the evolution of the fruit maturity stage in the field, and some biometric parameters such as trunk cross-section area, the annual vegetative growth, and fruiting shoots annual number were analyzed. The results highlighted the effect of compost fertilization on plants: almost all variants presented higher nitrogen amounts in leaves in the first and second years. Carbon content in leaves had a lower dynamic over time. Rootstock and compost fertilization influenced the fruit maturity dynamic, but a single pattern was not identified. Quince as pear rootstock expressed a higher sensitivity to compost application, the biometric parameters as trunk cross-section area, and almost all cultivars' annual vegetative growth were higher than the control's. Positive output can lead to future model upscaling in the farms and households.

Published: October 2024

This study explores the effectiveness of functional near-infrared spectroscopy (fNIRS) as an implicit measurement tool for evaluating sweetness intensity and affective value. Thirty-two participants tasted sucrose solutions at concentrations of 0.15M, 0.3M, and 0.6M, while both their neural responses were recorded with a 24-channel fNIRS system and their self-reported assessments of sweetness intensity and affective value were collected. The neural fNIRS data were converted into oxygenated hemoglobin (HbO) and deoxygenated hemoglobin (HbR) concentrations using the modified Beer-Lambert Law, and analyzed through univariate activation analysis and multivariable decoding analysis to identify neural activation patterns associated with sweetness perception. The results showed significant activation in the dorsolateral prefrontal cortex (dlPFC) and orbitofrontal cortex (OFC) in response to varying levels of sweetness intensity and affective value, with channels 8, 10, 12, 13, 14, 15, and 17 consistently activated across all sucrose concentrations. As sweetness concentration increased from 0.15M to 0.6M, the number of significantly activated channels rose from seven to eleven, indicating stronger and more widespread neural responses corresponding to higher sweetness intensity. The multivariable decoding analysis further demonstrated the capability of fNIRS in accurately distinguishing positive affective responses, with up to 72.1% accuracy. The moderate positive correlation between explicit self-reports and implicit fNIRS data regarding sweetness intensity further supports the validity of fNIRS as a reliable tool for assessing taste perception. This study highlights the potential of fNIRS in sensory neuroscience, demonstrating its effectiveness in capturing the neural mechanisms underlying sweet taste perception.

Published: October 2024

Background/Objectives: To describe the effects of muscle-targeted oral nutritional supplementation (MT-ONS) on nutrition, functional capacity, and other health outcomes in patients after femur fracture surgery; Methods: A prospective, open-label, single-center study was conducted. Patients aged 80+ post-femur fracture were recruited. They were assessed at baseline and after 90 days with MT-ONS, 100% whey protein enriched with leucine and vitamin D. Demographics, clinical and nutritional status (MNA®-SF), functional capacity [Barthel Index (BI), Lawton & Brody (LB) scale], muscle strength (dynamometry), cognition [Global Deterioration Scale (GDS)], tolerability, and satisfaction data were collected. Descriptive statistics were performed. Ethical approval was obtained; Results: Thirty-one patients (74% women, mean age 87 ± 3.99 years) were enrolled. At baseline, 32% were malnourished and 65% at risk. After ≥90 days of MT-ONS, malnutrition decreased to 13% and well-nourishment increased to 32%. Ninety percent gained weight, with significant muscle strength improvements (+2 kg, p<0.001). Eighty-one percent achieved a BI score ≥60 points [mean 84.8 (± 17.82)]. BI score improvements correlated with higher baseline muscle strength (rho=0.413, p=0.021) and better nutritional status (rho=0.464, p=0.009). LB mean score was 4.84 (± 2.26). Improvements correlated with pre-fracture BI score (rho=0.475, p=0.007). Positive correlations were noted between nutritional status, muscle strength, and functional outcomes. Cognition remained stable (GDS=1 in 67.7% patients). Tolerability and satisfaction with MT-ONS were high at 90%; Conclusions: MT-ONS, 100% whey protein enriched with leucine and vitamin D for ≥90 days, enhances nutritional status and functional recovery in patients after femur fracture surgery.

Published: October 2024

This study aimed to develop fermented cashew nut cheese alternative supplemented with Chondrus crispus and Porphyra sp. for enhancing their nutritional and sensory characteristics, as well as familiarizing consumers with seaweeds consumption. The impact of seaweeds supplementation was evaluated through analysis of some physicochemical, microbiological and organoleptic properties of the developed food products. The total lipids content decreased with the supplementation with seaweeds. Crude protein content also slightly decreased, while elemental analysis showed that mineral and trace elements (Ca, K, Mg, Na, Fe, I, Se, and Zn) content increased when C. crispus was added to the paste. The analyses of color and textural (TPA) attributes showed that theese were significantly influenced by adding seaweeds to the cashew paste. Generally, the microbiological results comply with the different European guidelines for assessing the microbiological safety of ready-to-eat foods placed on the market, except for aerobic mesophilic bacteria and marine agar counts. Flash Profile analysis al-lowed to distinguish samples attributes, showing an increased flavor complexity of plant-based cheese alterna-tives supplemented with seaweeds. Overall, the study indicates that seaweed enrichment mainly influenced the physicochemical and sensory characteristics of plant-based cheese alternatives.

Authors: Thirukonda Jegadeesh Babu Kiran Sooraj , Arif Khan Ismail
Published: October 2024

Obesity is a major public health concern globally, significantly increasing the risk of numerous metabolic and cardiovascular diseases. While lifestyle interventions remain the primary strategy for weight management, pharmacotherapy is increasingly recognized as an essential component for patients with obesity, especially when lifestyle modifications alone are insufficient. Glucagon-like peptide-1 (GLP-1) receptor agonists, originally developed for the management of type 2 diabetes, have emerged as effective agents in promoting weight loss in both diabetic and non-diabetic populations. This literature review examines the efficacy, safety, and mechanisms of action of GLP-1 receptor agonists, focusing on liraglutide and semaglutide, in obesity treatment. Furthermore, it discusses the impact of GLP-1 receptor agonists on obesity-related comorbidities, their comparison with other pharmacological treatments, and future perspectives.

Published: October 2024

Background: The use of salivary biomarkers offers a non-invasive approach to understanding the metabolic and inflammatory status of hypertensive patients. This study aimed to quantify the salivary nitric oxide (NO), total cholesterol, triglycerides, high-density lipoproteins (HDL), and low-density lipoproteins (LDL) levels in hypertensive individuals and healthy controls in a sub-population in Saudi Arabia.
Methods: This cross-sectional study comprised diagnosed hypertensive patients (test group, 40–50 years old) and age-matched healthy controls who visited the dental hospital in the College of Dentistry, King Khalid University, for dental treatment. Nitric oxide, total cholesterol, triglycerides, HDL, and LDL levels in saliva were assessed. An independent sample t-test was used to compare the results between the hypertensive and control groups.
Results: The study included 40 hypertensive patients (20 males and 20 females, aged 40-50) and 40 age-matched healthy individuals (20 males and 20 females). Significant differences in the triglyceride (p = 0.007), cholesterol (p = 0.033), and NO (p = 0.014) levels were observed between the two groups. The triglyceride level was significantly correlated with age in the test group (p = 0.04).
Conclusion: This study demonstrated significant differences in the nitrate levels and lipid profiles between hypertensive patients and healthy individuals in a sub-population in Saudi Arabia. The findings indicate that saliva can be used as a non-invasive diagnostic tool for assessing nitrate levels and the lipid profile. However, additional studies with larger sample sizes and more precise testing parameters are required to validate the findings.

Published: October 2024

Precise monitoring of NOx concentrations in nitric oxide delivery systems is crucial to ensure the safety and well-being of patients undergoing inhaled nitric oxide (iNO) therapy for pulmonary arterial hypertension. Currently, NOx sensing in commercialized iNO instruments predominantly relies on chemiluminescence sensors, which not only drives up costs but also limits their portability. Herein, we developed solid state gas sensors utilizing Ni-based sensing materials for effectively tracking the level of NO and NO2 in NO delivery system. These sensors comprised of NiO-SE or (NiFe2O4+30 wt.% Fe2O3)-SE vs. Mn-based RE demonstrated high selectivity towards 100 ppm NO under the interference of 10 ppm NO2 or 3 ppm NO2 under the interference of 100 ppm NO, respectively. Meanwhile, excellent stability, repeatability, and humidity resistance were also verified for proposed sensors. Sensing mechanisms were thoroughly investigated through assessments of adsorption capabilities and electrochemical reactivity. It turns out that the superior electrochemical reactivity of NiO towards NO, alongside with the NO2 favorable adsorption characteristics of (NiFe2O4 + 30 wt.% Fe2O3), is the primary reason for the high selectivity to NOx. These findings indicate a bright future for the application of these NOx sensors in innovative iNO treatment technologies.

Various methods have been studied to speed up the wound healing process. Promoting the rapid development of blood vessels, also known as angiogenesis, is essential as this significantly accelerates skin regeneration. This study identified a polysaccharide from the red alga Osmundea pinnatifida (PSOP) that promotes angiogenesis and accelerates wound healing. Firstly, we analyzed the structural characteristics of PSOP using various techniques such as UV-visible spectrum, Fourier-transform infrared (FT-IR) spectroscopy, X-ray diffraction (X-RD), scanning electron microscopy (SEM), and high-performance liquid chromatography coupled to refractive index detector (HPLC-RID). We also evaluated the antioxidant properties of PSOP in vitro using tests for DPPH free radical scavenging capacity, iron reduction capacity (RPA), and total antioxidant capacity (TAC). Additionally, we observed a significant increase in new blood vessel formation in the chorioallantoic membrane model (CAM assay) using a fertilized hen egg, indicating the pro-angiogenic effect of PSOP.
Furthermore, we tested the wound-healing potential of PSOP hydrogel in vivo using excision wounds in the Wistar rat model. The results showed a notable acceleration of wound closure and an improvement in tissue regeneration and collagen deposition quality within 11 days, indicating the strong wound-healing activity of PSOP. Our computational study suggested that the PSOP units bind to cyclooxygenase 2 (COX-2) and vascular endothelial growth factor (VEGF) with acceptable affinities and interactions, which might explain the observed beneficial wound healing properties and the pro-angiogenic effect seen in the experimental assays. Our findings support using the polysaccharide PSOP for wound treatment due to its antioxidant and pro-angiogenic potential.

This paper examined the chemoselectivity and diastereoslectivity of silyl nitronate alkenyn-nitroethers in Intramolecular Silyl Nitronate Cycloadditions (ISNC) to produce isoxazole derivatives with interesting medicinal properties. These reactions resulted in the formation of either dihydrofuro[3,4-c]isoxazolines/isoxazolidines and/or alkynyl moieties attached to 2,5-dihydrofuryl carbonyls. It also discerned the diastereoselectivity of the resulting cyclic adducts and compared those to previous findings. The reactions were also investigated with Spartan molecular modeling computations to aide in the understanding of any displayed chemo- and/or stereoselectivity. These [3+2]-cycloaddition reactions demonstrated excellent to complete chemospecificity. The cycloadditions also demonstrated remarkable diastereospecificity in that each diastereomer of the nitroethers resulted in the formation of only one of four possible diastereomeric outcomes. The stereochemistry of the major diastereomers did not agree with previously published findings.

Authors: Mattiuzzi Camilla , Lippi Giuseppe
Published: October 2024

Background and Objective: Obtaining reliable and up-to-date information on mortality causes is essential for planning and implementation of effective preventive interventions. We present here an analysis of the leading causes of death in the US in 2022. Material and Methods: We conducted an electronic search of the US Centers for Control and Prevention (CDC) Web-based Injury Statistics Query and Reporting System (WISQARS) to obtain information on the leading causes of death in the US for the most recent searchable year (2022), stratified by age and sex. Results: Overall, heart disease was the leading cause of death (26.2% of all deaths), followed by malignant neoplasms (22.7%), unintentional injuries (8.5%) and coronavirus disease 2019 (COVID-19; 6.9%). Although heart disease and malignant neoplasms remained the leading causes of death in both sexes, unintentional injuries were the third cause for men (10.5%), while strokes were the third cause in women (7.5%). COVID-19 remained the fourth most common cause of death in both sexes (7.1% in men and 6.8% in women). The ten most common causes of death showed an increasing mortality tendency in parallel with the aging of population, with similar trends for both sexes. The only exception was unintentional injury, which was the most common cause of death in both sexes between the ages of 15 and 44 years, then reached a plateau, for increasing again in people aged 65 years or older. Conclusions: Greater efforts should be put into prevention and education, as heart disease, cancer and even unintentional injuries are preventable diseases.

This quantitative approach for metabolite analysis provides a viable method for screening these fungal strains, highlighting their potential for sustainable production of cyclic glycine-proline (cGP).
Oxidative Stress and Antioxidation in Testicular Leydig: Implications for Male Fertility
Authors: Zhang Ming , Tang Yujun , Li Hao , Zhou Guangbin , Zeng Changjun
Published: October 2024

Leydig cells, pivotal for male fertility, undergo significant oxidative stress due to their proximity to macrophages and reactive oxygen species (ROS) generated by extracellular structures. This stress disrupts Leydig cell function, impairing steroidogenesis and spermatogenesis, ultimately leading to male infertility. Oxidative stress triggers apoptosis and inhibits testosterone production, crucial for spermatogenesis regulation. Understanding the mechanisms of oxidative stress and antioxidation on Leydig cells is vital. Some studies highlight the role of antioxidants in mitigating oxidative damage, emphasizing critical pathway of Sirt1 in oxidative stress and Nrf2 in antioxidation. Future research should focus on screening antioxidant substances and optimizing antioxidant dosages for Leydig cell protection and testosterone restoration, thereby enhancing reproductive performance. This review provides insights into combating male infertility by addressing Leydig cell oxidative stress and antioxidation.
Exploring the Research Gaps on the Long-Term Effects of Soccer Headers: A Meta-Review of Existing Evidence
Authors: Espinosa Ricardo David , Flahault Antoine
Published: October 2024

Background: The practice of heading in soccer is widely recognized as an important aspect of the game both offensively and defensively, frequently implemented by players. However, concerns persist about the negative impact of this technique on players' cognitive function and symptoms, both in the short and long-term. This meta-review aims to systematically map the existing literature on soccer heading and its implications on the long-term effects; Methods: We conducted a meta-review of systematic reviews following PRISMA-ScR guidelines in PubMed, Embase and Web of Science databases. Searches were conducted between 21 February and 20 March 2024, in English, with a limitation to articles published between January 2000 and March 2024.; Results: Three systematic reviews were eligible for having addressed the subject of head-ball impacts in soccer and their physiological, neurological and cognitive impact. While most studies did not report any significant long-term changes, short-term impairments in memory and reaction time were observed in some instances, normalizing within 24 hours. Neurochemical markers showed mixed results, with increased NF-L levels persisting up to a month in certain cases. Visual reflexes and corticomotor inhibition also exhibited temporary dysfunctions post-heading; Conclusions: This meta-review highlighted the limited number of systematic reviews on the effects of heading in soccer in young and adult players. The current evidence suggests that while heading may lead to short-term cognitive and physiological changes, the long-term effects remain uncertain and probably under-studied. Further research, particularly with professional players and standardized methodologies on long-term follow-up, is needed to clarify these potential risks and inform safety measures in soccer.
