Hypidone hydrochloride (YL-0919) ameliorates functional deficits after traumatic brain injury in mice by activating the sigma-1 receptor for antioxidation.

JOURNAL/nrgr/04.03/01300535-202508000-00023/figure1/v/2024-09-30T120553Z/r/image-tiff Traumatic brain injury involves complex pathophysiological mechanisms, among which oxidative stress significantly contributes to the occurrence of secondary injury. In this study, we evaluated hypidone hydrochloride (YL-0919), a self-developed antidepressant with selective sigma-1 receptor agonist properties, and its associated mechanisms and targets in traumatic brain injury. Behavioral experiments to assess functional deficits were followed by assessment of neuronal damage through histological analyses and examination of blood-brain barrier permeability and brain edema. Next, we investigated the antioxidative effects of YL-0919 by assessing the levels of traditional markers of oxidative stress in vivo in mice and in vitro in HT22 cells. Finally, the targeted action of YL-0919 was verified by employing a sigma-1 receptor antagonist (BD-1047). Our findings demonstrated that YL-0919 markedly improved deficits in motor function and spatial cognition on day 3 post traumatic brain injury, while also decreasing neuronal mortality and reversing blood-brain barrier disruption and brain edema. Furthermore, YL-0919 effectively combated oxidative stress both in vivo and in vitro. The protective effects of YL-0919 were partially inhibited by BD-1047. These results indicated that YL-0919 relieved impairments in motor and spatial cognition by restraining oxidative stress, a neuroprotective effect that was partially reversed by the sigma-1 receptor antagonist BD-1047. YL-0919 may have potential as a new treatment for traumatic brain injury.

Effect of structure on sensing performance of nitro explosives with high sensitivity and mechanism of two Tb(III) coordination polymers.

The use of a conjugate N-containing ligand resulted in the decreasing of structural dimensions from 2D network of [Tb(2-pyia)(Ac)(H2O)] (CP1) to 1D chain [Tb(2-pyia)(Ac)(IDP)] (CP2) (2-H2pyia = 5-(pyridin-2-ylmethoxy) isophthalic acid and IDP=imidazo[4,5-f]-[1,10] phenanthroline). Both of them exhibit the characteristic luminescence of Tb ions and could have high fluorescence sensing properties for cefixime and fluridine. The different sensing properties for nitro explosives are manifested as CP1 for nitrobenzene and CP2 for 4-nitrophenol due to the difference in structure. Furthermore, CP2 exhibits the ratiometric fluorescence sensing for Fe3+ ion with a low detection limit of 0.405 µM. The fluorescence sensing mechanism of the two Tb complexes for different analytes was investigated using experimental methods and theoretical calculations. CP1 was used for the detection of Flu residues in the actual system and better results were obtained. The work shows the introduction of the chelated ligand might affect the structural and sensing performance changes of coordination polymers.

Influence of freeze-thaw process on As migration and microorganisms in aggregates of paddy soil.

A natural phenomenon known as the seasonal freeze-thaw (FT) cycle happens in cold temperature zone such as high latitude and high altitude regions where the soil frequently freezes and thaws in response to temperature variations. Global warming would increase the number of FT cycles in FT regions. However, the influence of FT process on arsenic (As) migration in paddy soil is seldom investigated. Herein, indoor simulation experiment was conducted to investigate the influence of FT process (60 cycles) on As migration from surface to deep soil and microorganisms in paddy soil column. Compared to non FT treatment groups, the concentrations of As in microaggregates of 8-10 cm depth and 18-20 cm depth in soil column of FT treatment group increased by 3.69 mg/kg and 4.16 mg/kg, respectively; the concentrations of As in macroaggregates of 8-10 cm depth and 18-20 cm depth in soil column of FT treatment group increased by 3.34 mg/kg and 3.94 mg/kg, respectively, indicating that FT process accelerated the As migration from surface to deep soil. FT process affected the microbial community structure by changing the physicochemical properties of the soil, which decreased the diversity and uniformity of bacterial community distribution in the soil. The relative abundance of two As-resistant bacteria, e.g., Sphingomonas and Lysobacter, increased by 8.2% and 11.35% after 60 cycles, respectively; moreover, total As in the soil was significantly (p < 0.05) negatively correlated with the alpha index of the soil microorganisms. This study would provide basic data for future study on determining environmental behavior and risk of metals in farm soils in seasonal FT aeras.

Enhanced surface antimicrobial, biocompatible and mechanical properties of 3D printed titanium alloys by electrophoretic deposition of chitosan/ZnO.

In this study, to address the susceptibility of 3D-printed titanium implants to bacterial infection, we propose to form a chitosan/ZnO composite coating by electrophoretic deposition to enhance its antimicrobial, biocompatible, and mechanical properties. The surface morphology of the composite coating is relatively flat, showing good hydrophilicity and coating adhesion, and the corrosion current density is significantly lower than that of the untreated titanium alloy. According to the results of the study, the composite coatings containing more than 0.1 g of ZnO (Z2, Z3, Z4 groups) showed excellent antibacterial effects against Staphylococcus aureus and Escherichia coli, with antibacterial rates of more than 95 %, and the medium-concentration ZnO coatings (Z2 group) showed good cellular activity, with cell viability rates of more than 80 %. In contrast, the high-concentration ZnO coatings (Z3, Z4 groups) showed a certain degree of cytotoxicity. The inherent film-forming property of the composite coating enabled the cells to adhere well to the coating surface. It was found through SBF body fluid immersion that Zn²âº can increase the rate of hydroxyapatite precipitation and enhance bioactivity. These results emphasize the importance of precise control of the ZnO content in the improved antimicrobial and biocompatible chitosan-ZnO composite coatings to ensure excellent antimicrobial properties and necessary biocompatibility.

Efficacy and Safety of Sacubitril/Allisartan for the Treatment of Primary Hypertension.

Background: The prevalence of hypertension still increases with the very rapidly increasing longevity in some countries, such as China. The control rate remains low. Objectives: This randomized, double-blind, phase 3 study assessed the efficacy and safety of sacubitril/allisartan, compared with olmesartan in Chinese patients with mild-to-moderate hypertension. Methods: Eligible patients aged 18 to 75 years (n = 1,197) with mild-to-moderate hypertension were randomized to receive sacubitril/allisartan 240 mg (n = 399), sacubitril/allisartan 480 mg (n = 399), or olmesartan 20 mg (n = 399) once daily for 12 weeks. Patients who completed the 12-week treatment then received another 12-week extended treatment (n = 1,084) and 28-week prolonged treatment (n = 189). The primary end point was a reduction in clinic mean sitting systolic blood pressure (msSBP) from baseline at 12 weeks. Results: Sacubitril/allisartan 240 mg/d provided a greater reduction in msSBP than olmesartan at 12 weeks (between-group difference: -1.9 mm Hg [95% CI: -4.2 to 0.4 mm Hg]; P = 0.0007, for noninferiority). Sacubitril/allisartan 480 mg/d provided a significantly greater reduction in msSBP than olmesartan at 12 weeks (between-treatment difference: -5.0 mm Hg [95% CI: -7.3 to -2.8 mm Hg]; P < 0.001, for superiority). Greater reductions in 24-hour, and daytime and nighttime systolic and diastolic blood pressure were also observed with both doses of sacubitril/allisartan compared with olmesartan (P ≤ 0.001 for 480 mg/d). The blood pressure reductions tended to be dose-dependent for sacubitril/allisartan. Sacubitril/allisartan was well tolerated, and no cases of angioedema or death were reported. Conclusions: Sacubitril/allisartan is effective for the treatment of hypertension and well tolerated in Chinese patients.

Moderate physical activity and higher frequency are inversely associated with incidence of frailty in middle-aged and older population: a 4-year longitudinal study in Europe.

BACKGROUND: Global aging is leading to an increase in frailty patients, and physical activity (PA) may have an impact on frail in middle-aged and older population. This study aimed to explore the relationship between the frequency of different PA intensities and the incidence and prevalence of frailty in middle-aged and older adults based on the Survey of Health, Ageing, and Retirement in Europe (SHARE). METHOD: Self-reported questionnaires were used to obtain information on demographics and PA, and frailty was assessed using the SHARE Frailty Instrument (SHARE-FI). Cox regression and logistic regression models were used to explore the association between PA and frailty and stratified according to middle or old age. RESULTS: Among 6315 baseline non-frail participants aged 44-96 years, 16.1% developed frailty over 4 years, with higher incidence and prevalence in women (P < 0.05). Women accounting for 55.80% of the sample. The frequency of participants participating in sports decreased over 4 years (P < 0.05). Compared with participants who engaged in PA more than once a week, participants who engaged in moderated PA less frequently had a higher risk of new-onset frailty (HR: 3.174-6.115), and participants who engaged in vigorous PA 1-3 times a month had a higher risk of new-onset frailty (HR: 1.335). Participation in low-frequency moderate PA and vigorous PA 1-3 times per month were positively associated with the prevalence of frailty (P < 0.05). CONCLUSION: Physical activity frequency decreases with age in middle-aged and older adults. Those adults who engage in moderate PA more than once a week have a lower risk of incidence of frailty, compared to those with more sedentary life-styles. Additionally, women need to pay more attention to frailty management.

Nanozyme linked multi-array gas driven sensor for real-time quantitative detection of Group A streptococcus.

Group A streptococcus (GAS) is a pathogen typically transmitted through respiratory droplets and skin contact, causing an estimated 700 million mild non-invasive infections worldwide each year. There are approximately 650 000 infections that progress to severe invasive infections, even resulting in death. Therefore, the ability to detect GAS rapidly, accurately and in real time is important. Herein, we developed a nanozyme linked multi-array gas driven sensor (NLMAGS) to point-of-care testing of GAS within 2 h. The NLMAGS demonstrated excellent performance as it combined the advantages of nanozyme techniques, immunoassay techniques, and 3D printing techniques. Platinum- and palladium-rich nanozyme particles (Au@Pt@PdNPs) were synthesized and used to label monocloning antibodies as detection probes. Magnetic beads were labeled with monocloning antibodies as capture probes to establish a double-antibody sandwich immunoassay for the detection of GAS. The sandwich immune complex can catalyze the H2O2 substrate and produce O2. GAS quantification can be achieved by measuring the distance that the O2 pushes the ink drops forward in the sensor. Under optimized conditions, the NLMAGS quantitatively detected 24 spiked samples with a limit of detection (LOD) of 62 CFU mL-1, which was 5 times lower than that of ELISA (334 CFU mL-1). A strong correlation with the conventional ELISA was found (r = 0.99, P < 0.001). In comparison, the traditional lateral flow immunoassay based on Au@Pt@PdNPs-mAb2 (Au@Pt@PdNPs-LFIA) had a LOD of 104 CFU mL-1, which was significantly higher than that of NLMAGS. The NLMAGS demonstrated excellent sensitivity to GAS. The intra- and inter-assay precisions of the sensor were below 15%. Overall, the established NLMAGS has promising potential as a rapid and quantitative method for detecting GAS and can also be used to detect various pathogens.

[Effects of tree species assembly on bioavailable P components in rhizosphere soil of southern subtropical plantation]. / å—äºšçƒ­å¸¦äººå·¥æž—æ ‘ç§é ç½®å¯¹æ ¹é™ åœŸå£¤ç”Ÿç‰©æœ‰æ•ˆç£·çš„å½±å“.

Improving the availability of soil phosphorus (P) and promoting tree growth through tree species selection and assembly are the critical issue. We conducted an afforestation experiment following randomized block experimental design with 1, 2, 4, and 6 tree species richness in south subtropics, including Pinus massoniana, Mytilaria laosensis, Erythrophleum fordii, Castanopsis hystrix, Michelia macclurei, Manglietia glauca, Aquilaria sinensis, and Dalbergia odorifera. We measured the bioavailable P components (CaCl2-P, citrate-P, enzyme-P and HCl-P) and examined the effects of different tree species assembly on bioavailable P components and tree growth. The results showed that, compared with non-nitrogen-fixing tree species, the mixing of nitrogen-fixing tree species (E. fordii and D. odorifera) effectively increased the contents of soil water, total nitrogen, total phosphorus, and microbial biomass P (MBP). The assembly of specific tree species improved the accumulation of bioavailable P. Mixing of nitrogen-fixing tree species significantly increased CaCl2-P content by 46.2% to 160.3%, the enzyme-P content produced by microbial mineralization by 69.3% to 688.2%, and HCl-P by 31.5% to 81.3%, increased MBP by 81.8% to 149.4%, and microbial biomass N (MBN) by 88.1% to 160.6%, respectively. Redundancy and correlation analysis results showed that MBP, available P, total phosphorus, L-leucine aminopeptidase, cellobiose, acid phosphatase, MBN and soil organic carbon were key factors driving the variation of rhizosphere soil bioavailable P. Mixing of nitrogen-fixing tree species increased enzyme-P and citrate-P, and the availability of which were positively correlated to tree basal area. In this study, mixing of nitrogen-fixing tree species increased the rhizosphere soil bioavailable P content, which facilitates tree growth.

Right ventricular function and determining factors of dysfunction in ST-segment-elevation myocardial infarction: a cross-sectional study with cardiac magnetic resonance imaging (MRI).

Background: Over the past few decades, left ventricular (LV) dysfunction in ST-segment elevation myocardial infarction (STEMI) patients has been the focus of research. Recently, co-occurring right ventricular (RV) dysfunction has received more attention in clinical practice. We aimed to assess RV function using cardiac magnetic resonance (CMR) imaging and identify factors that may contribute to RV dysfunction in STEMI patients. Methods: We retrospectively studied 189 patients with STEMI who underwent CMR 1-7 days after successful percutaneous coronary intervention (PCI). The ejection fraction (EF), wall thickening rate (WTR), peak radial strain (RS), circumferential strain (CS) and longitudinal strain (LS) of the LV, interventricular septum (IVS) and RV were measured with cine images. The location and extent of the infarct were determined using late gadolinium enhancement (LGE) imaging. The differences of function between STEMI patients with right ventricular ejection fraction (RVEF) <50% and those with RVEF ≥50% were compared using an independent-sample t-test. Linear regression analyses were used to determine independent predictors of RVEF. Results: RVEF <50% was observed in 32.28%% STEMI patients, who also demonstrated significantly lower left ventricular ejection fraction (LVEF), WTR, RS, CS, LS and larger infarct sizes than those with RVEF ≥50%. Patients with RVEF <50% also demonstrated a higher incidence of RV infarction, higher RV end-systolic volume (ESV) index, and lower RV RS and CS. Multivariable linear regression analysis revealed LV EF, IVS WTR and IVS RS as significant predictors for RVEF, while male gender, the culprit lesion in the right coronary artery (RCA), peak troponin were negative predictors for RVEF. Notably, peak troponin, LV EF, LV RS, LV CS, LV WTR, and IVS WTR demonstrated higher area under the curve (AUC) values for predicting RV dysfunction. Conclusions: RV dysfunction was detected in 32.28% of STEMI patients. Patients with acute STEMI and RVEF <50% had impaired LV and IVS functions. Systolic function of the LV and IVS, peak troponin, and culprit lesions in the RCA were independent predictors of RV dysfunction in STEMI patients.

Metagenomic versus targeted next-generation sequencing for detection of microorganisms in bronchoalveolar lavage fluid among renal transplantation recipients.

Background: Metagenomic next-generation sequencing (mNGS), which provides untargeted and unbiased pathogens detection, has been extensively applied to improve diagnosis of pulmonary infection. This study aimed to compare the clinical performance between mNGS and targeted NGS (tNGS) for microbial detection and identification in bronchoalveolar lavage fluid (BALF) from kidney transplantation recipients (KTRs). Methods: BALF samples with microbiological results from mNGS and conventional microbiological test (CMT) were included. For tNGS, samples were extracted, amplified by polymerase chain reaction with pathogen-specific primers, and sequenced on an Illumina Nextseq. Results: A total of 99 BALF from 99 KTRs, among which 93 were diagnosed as pulmonary infection, were analyzed. Compared with CMT, both mNGS and tNGS showed higher positive rate and sensitivity (p<0.001) for overall, bacterial and fungal detection. Although the positive rate for mNGS and tNGS was comparable, mNGS significantly outperformed tNGS in sensitivity (100% vs. 93.55%, p<0.05), particularly for bacteria and virus (p<0.001). Moreover, the true positive rate for detected microbes of mNGS was superior over that of tNGS (73.97% vs. 63.15%, p<0.05), and the difference was also significant when specific for bacteria (94.59% vs. 64.81%, p<0.001) and fungi (93.85% vs. 72.58%, p<0.01). Additionally, we found that, unlike most microbes such as SARS-CoV-2, Aspergillus, and EBV, which were predominantly detected from recipients who underwent surgery over 3 years, Torque teno virus (TTV) were principally detected from recipients within 1-year post-transplant, and as post-transplantation time increased, the percentage of TTV positivity declined. Conclusion: Although tNGS was inferior to mNGS owing to lower sensitivity and true positive rate in identifying respiratory pathogens among KTRs, both considerably outperformed CMT.

Revealing the lethal effects of Pasteurella multocida toxin on multiple organ systems.

Pasteurella multocida toxin (PMT) is one of the most important virulence factors of Pasteurella multocida type D. Pasteurella multocida infection has caused enormous economic losses in the pig farming industry. Although it is well known that this bacterial infection causes progressive atrophic rhinitis, its effects on other organ tissues in pigs are unclear. In this study, PMT was expressed and purified, and the cytotoxic effects of PMT on four types of swine cells, LLC-PK1, PAM, IPEC, and ST, were investigated. LLC-PK1 exhibited the highest sensitivity to the cytotoxic effects of PMT. Our studies revealed that a PMT concentration of 0.1 µg/kg can lead to weight loss, whereas a PMT concentration of 0.5 µg/kg can lead to death in mice. PMT causes damage to the intestines, kidneys, lungs, livers, and spleens of mice. Furthermore, PMT caused acute death in pigs at treatment concentrations greater than 5 µg/kg; at PMT concentration of 2.5 µg/kg, weight loss occurred until death. PMT mainly caused damage to the hearts, lungs, livers, spleens and kidneys of pigs. The organ coefficient showed that damage to the heart and kidneys was the most severe and caused the renal pelvis and renal pyramid to dissolve and become cavitated. Pathology revealed hemorrhage in the lungs, liver, and spleen, and the kidneys were swollen and vacuolated, which was consistent with the damaged target organs in the mice. In conclusion, these findings demonstrate that PMT is extremely toxic in vitro and in vivo, causing damage to various organs of the body, especially the kidneys and lungs. This study provides a theoretical basis for the in-depth exploration of the cytotoxic effects of PMT on target organs.

Impact of Wearable Device-Based Walking Programs on Gait Speed in Older Adults: A Systematic Review and Meta-Analysis.

Background: As walking abilities are widely affected among the aging population, investigating the effectiveness of wearable device-based walking programs is essential. The intentions of this meta-analysis were to investigate their effects on gait speed among older adults, as well as to include subgroup analysis to evaluate potential effects on individuals with aging-related conditions such as Parkinson's disease (PD) and stroke. Methods: Systematic retrieval of Pubmed, The Cochrane Library, Embase and Web of Science databases were searched up to February 2024. Outcomes such as gait speed, balance, cadence, and stride length were extracted and analyzed. Study quality was evaluated using the Rob 2 tool and heterogeneity was tested using I2 statistics through STATA 16. Results: Nine studies with 284 participants were analyzed. The intervention group showed a significant improvement in gait speed (weighted mean difference (WMD) 0.12; 95% CI 0.03 to 0.21). There is a subgroup analysis suggesting differential effects: significant improvements in PD and stroke subgroups, but not in the normal aging group. Balance (WMD: 1.93; 95% CI: 0.20 to 3.66) and stride length (WMD: 8.58; 95% CI: 3.04 to 14.12) were also shown to improve, but the heterogeneity across the studies was moderate (I2 = 63.91%). No significant changes were observed in the Timed Up and Go test, Gait Variability, and Step Width. Conclusions: Wearable device-based walking programs improve gait speed in older adults, with top notch advantages in the ones tormented by PD or stroke. These findings advocate that such interventions can be a valuable part of individualized treatment strategies in geriatric care, aiming to enhance mobility and usual satisfactory of existence.

Comparative Study of PtM (M=Cu, Zn, Ga, Mn, Fe, In, Ce) Bimetals on Zincosilicate for Propane Dehydrogenation Reaction.

Silicoaluminate zeolites have relatively strong Brönsted (B) acid properties that can easily lead to deep cracking reactions, making them less favourable as carriers for propane dehydrogenation. Here, we utilise zincosilicate zeolite with less B-acid produced by the introduction of the heteroatom Zn into the framework as a carrier, followed by simultaneous ion exchange (IE) of M monometallic or PtM bimetallic (M = Cu, Zn and Ga, etc.). The optimized PtZn/Zn-4 exhibits a superior propane dehydrogenation performance over PtCu/Zn-4 and PtGa/Zn-4, which can achieve a propane conversion of about 30% in a pure propane atmosphere at 550 °C and can be operated for at least 168 h without significant deactivation. Characterization techniques such as spherical aberration corrected transmission electron microscopy, in situ X-ray photoelectron spectroscopy, and in situ diffuse reflectance infrared fourier transform spectroscopy with different gas adsorptions are used to investigate these PtM@zeolite catalysts in order to deepen the understanding of acid site identification, promoter effect and catalysis.

Smartphone-Assisted Nanozyme Colorimetric Sensor Array Combined "Image Segmentation-Feature Extraction" Deep Learning for Detecting Unsaturated Fatty Acids.

Conventional methods for detecting unsaturated fatty acids (UFAs) pose challenges for rapid analyses due to the need for complex pretreatment and expensive instruments. Here, we developed an intelligent platform for facile and low-cost analysis of UFAs by combining a smartphone-assisted colorimetric sensor array (CSA) based on MnO2 nanozymes with "image segmentation-feature extraction" deep learning (ISFE-DL). Density functional theory predictions were validated by doping experiments using Ag, Pd, and Pt, which enhanced the catalytic activity of the MnO2 nanozymes. A CSA mimicking mammalian olfactory system was constructed with the principle that UFAs competitively inhibit the oxidization of the enzyme substrate, resulting in color changes in the nanozyme-ABTS substrate system. Through linear discriminant analysis coupled with the smartphone App "Quick Viewer" that utilizes multihole parallel acquisition technology, oleic acid (OA), linoleic acid (LA), α-linolenic acid (ALA), and their mixtures were clearly discriminated; various edible vegetable oils, different camellia oils (CAO), and adulterated CAOs were also successfully distinguished. Furthermore, the ISFE-DL method was combined in multicomponent quantitative analysis. The sensing elements of the CSA (3 × 4) were individually segmented for single-hole feature extraction containing information from 38,868 images of three UFAs, thereby allowing for the extraction of more features and augmenting sample size. After training with the MobileNetV3 small model, the determination coefficients of OA, LA, and ALA were 0.9969, 0.9668, and 0.7393, respectively. The model was embedded in the smartphone App "Intelligent Analysis Master" for one-click quantification. We provide an innovative approach for intelligent and efficient qualitative and quantitative analysis of UFAs and other compounds with similar characteristics.

Using Transcriptomics to Determine the Mechanism for the Resistance to Fusarium Head Blight of a Wheat-Th. elongatum Translocation Line.

Fusarium head blight (FHB), caused by the Fusarium graminearum species complex, is a destructive disease in wheat worldwide. The lack of FHB-resistant germplasm is a barrier in wheat breeding for resistance to FHB. Thinopyrum elongatum is an important relative that has been successfully used for the genetic improvement of wheat. In this study, a translocation line, YNM158, with the YM158 genetic background carrying a fragment of diploid Th. elongatum 7EL chromosome created using 60Co-γ radiation, showed high resistance to FHB under both field and greenhouse conditions. Transcriptome analysis confirmed that the horizontal transfer gene, encoding glutathione S-transferase (GST), is an important contributor to FHB resistance in the pathogen infection stage, whereas the 7EL chromosome fragment carries other genes regulated by F. graminearum during the colonization stage. Introgression of the 7EL fragment affected the expression of wheat genes that were enriched in resistance pathways, including the phosphatidylinositol signaling system, protein processing in the endoplasmic reticulum, plant-pathogen interaction, and the mitogen-activated protein kinase (MAPK) signaling pathway at different stages after F. graminearium infection. This study provides a novel germplasm for wheat resistance to FHB and new insights into the molecular mechanisms of wheat resistance to FHB.

A smartphone-based immunochromatographic strip platform for on-site quantitative detection of antigenic targets.

To report the testing signal of an immunochromatographic assay for on-site quantitative detection, a portable and user-friendly smartphone-based biosensing platform is developed in this study. This innovative system is composed of an ambient light sensor inherent smartphone reader and a 3D-printed handhold device, a quantitative tool capable of directly interpreting carbon nanoparticle (CNP)-conjugated immunochromatographic strips. To showcase the platform capability, the smartphone-based immunochromatography system (SPICS) reader and device were successfully used in CNP strips for rapid detection of the early pregnancy marker human chorionic gonadotropin in female urine (HCG; limit of detection [LOD]: 0.30 mIU mL-1), prostate-specific antigen in patient blood (PSA; LOD: 0.28 ng mL-1) and ampicillin residue in animal milk (AMP; LOD: 0.23 ng mL-1). The results were fully correlated with conventional commercial instruments (R2 = 0.99). The SPICS platform exhibits significant advantages, including portability, cost-effectiveness, easy operation, and rapid and quantitative detection, making it a valuable on-site diagnosis tool for use in home and community healthcare facilities.
