Tolerance enhancement of Dendrobium officinale by salicylic acid family-related metabolic pathways under unfavorable temperature.

BACKGROUND: Unfavorable temperatures significantly constrain the quality formation of Dendrobium officinale, severely limiting its food demand. Salicylic acid (SA) enhances the resistance of D. officinale to stress and possesses various analogs. The impact and mechanism of the SA family on improving the quality of D. officinale under adverse temperature conditions remains unclear. RESULTS: Combined with molecular docking analysis, chlorophyll fluorescence and metabolic analysis after treatments with SA analogues or extreme temperatures are performed in this study. The results demonstrate that both heat and cold treatments impede several main parameters of chlorophyll fluorescence of D. officinale, including the ΦPSII parameter, a sensitive growth indicator. However, this inhibition is mitigated by SA or its chemically similar compounds. Comprehensive branch imaging of ΦPSII values revealed position-dependent improvement of tolerance. Molecular docking analysis using a crystal structure model of NPR4 protein reveals that the therapeutic effects of SA analogs are determined by their binding energy and the contact of certain residues. Metabolome analysis identifies 17 compounds are considered participating in the temperature-related SA signaling pathway. Moreover, several natural SA analogs such as 2-hydroxycinnamic acid, benzamide, 2-(formylamino) benzoic acid and 3-o-methylgallic acid, are further found to have high binding ability to NPR4 protein and probably enhance the tolerance of D. officinale against unfavorable temperatures through flavone and guanosine monophosphate degradation pathways. CONCLUSIONS: These results reveal that the SA family with a high binding capability of NPR4 could improve the tolerance of D. officinale upon extreme temperature challenges. This study also highlights the collaborative role of SA-related natural compounds present in D. officinale in the mechanism of temperature resistance and offers a potential way to develop protective agents for the cultivation of D. officinale.

A UCMPs@MIL-100 based thermo-sensitive molecularly imprinted fluorescence sensor for effective detection of ß-lactoglobulin allergen in milk products.

In this study, a thermo-sensitive molecularly imprinted fluorescence sensor was developed for the specific detection of ß-Lactoglobulin (ß-LG) allergen in milk products. The metal-organic frameworks (MIL-100) with a high specific surface area was coated on the surface of upconversion micro-particles (UCMPs). As the core, an imprinted polymer layer allowing for swelling and shrinking with response to temperature was prepared, which exhibited high adsorption and mass transfer capabilities for ß-LG allergen. The fluorescence intensity of UCMPs@MIL-100@MIP decreased linearly with the concentration of ß-LG in the range of 0.1-0.8 mg mL-1, and the limit of detection was 0.043 mg mL-1. The imprinting factor reached 3.415, which indicated that excellent specificity of the UCMPs@MIL-100@MIP for ß-LG allergen. In the analysis of ß-LG allergen in actual milk samples, the proposed UCMPs@MIL-100@MIP fluorescence sensor produced reliable and accurate results (recovery: 86.0-98.4%, RSD: 2.8-6.8%), closely related to the results of standard HPLC method (correlation coefficient: 0.9949), indicating that its feasibility in the detection of ß-LG allergen.

Epifriedelinol Ameliorates DMBA-Induced Breast Cancer in Albino Rats by Regulating the PI3K/AKT Pathway.

We evaluated the protective effect of epifriedelinol against breast cancer and postulated an underlying mechanism. Breast cancer was induced by a single dose of 50 mg/kg 7,12-Dimethylbenanthracene (DMBA), and rats were treated with 100 or 200 mg/kg (i.p.) epifriedelinol for 4 weeks. We then evaluated the effect of epifriedelinol on tumor growth, oxidative stress and serum inflammatory cytokine levels in DMBA-induced breast cancer. Protein and mRNA levels were determined using western blotting and quantitative reverse transcription polymerase chain reaction, respectively. The tumor volume and weight were significantly (p < 0.01) decreased in the epifriedelinol-treated group compared to the negative control group. Epifriedelinol decreased the altered levels of oxidative stress and serum inflammatory cytokines in rats with DMBA-induced breast cancer. Protein levels of PI3K, AKT and mTOR and mRNA levels of PI3K, AKT, Map3k1, Erbb2 and Pdk1 were decreased in the mammary tissue of epifriedelinol-treated rats with DMBA-induced breast cancer. Apoptosis was significantly induced in the epifriedelinol-treated group compared to the negative control group. In conclusion, epifriedelinol ameliorates DMBA-induced breast cancer by regulating the PI3K/AKT pathway.

Platelet-lymphocyte ratio is an independent prognostic factor in patients with ALK-positive non-small-cell lung cancer.

AIM: As the prognostic value of the neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) is unclear in patients with ALK-positive non-small-cell lung cancer (NSCLC), this study assessed the importance of these factors was in this patient subset. PATIENTS & METHODS: In 173 patients with primary ALK-positive NSCLC at pathological stages I-IV, neutrophil, platelet, lymphocyte, D-dimer and eosinophil levels were recorded before starting treatment. RESULTS: The patients' median NLR and PLR values were 2.10 and 127.69, respectively. Univariate analyses showed that NLR and PLR values, the D-dimer level and the eosinophil count were all associated with survival. Although multivariate analysis showed PLR to be an independent prognostic factor for overall survival (p = 0.018), NLR was not. CONCLUSION: PLR is an independent prognostic factor in ALK-positive NSCLC.

Psychological burden of hearing-impaired children and their parents through the COVID-19 pandemic.

Objective: Childhood hearing impairment has potential repercussions on the mental well-being of both children and their parents. As a vulnerable population in accessing health care services, they may face specific challenges, especially during the COVID-19 pandemic. This cross-sectional study aims to investigate the association between childhood hearing impairment and the mental health of children and their parents, and to assess health care utilization of hearing-impaired children and its impact on mental outcomes for both during the COVID-19 pandemic. Methods: Using the National Health Interview Survey (NHIS) database, we analyzed data for 15,989 children aged 5-17 and their corresponding parents. The correlations between childhood hearing impairment and mental outcomes were examined using logistic regression models. The 2020 (quarter 3 and quarter 4)-2021 NHIS data was singled out and re-analyzed, focusing on the utilization of medical care during the COVID-19 pandemic. Results: After accounting for covariates, hearing-impaired children exhibited a higher frequency of anxiety (OR 2.33, 95% CI 1.79-3.02) or depression (OR 2.14, 95% CI 1.59-2.88). Parents of hearing-impaired children had significantly higher odds of a higher frequency of anxiety (OR 1.55, 95% CI 1.20-2.01) or depression (OR 1.73, 95% CI 1.30-2.29). Interaction effect of hearing impairment with survey year on parents' mental health outcomes was observed (p for interaction <0.1). Children with hearing loss had higher odds of reporting delayed medical care (OR 2.00, 95% CI 1.11-3.59) or canceled medical care (OR 1.96, 95% CI 0.98-3.96, p = 0.059) due to the pandemic. Delayed medical care (OR 12.41, 95% CI 2.78-55.46) or canceled medical care (OR 6.26, 95% CI 1.28-30.75) due to the COVID-19 pandemic significantly contributed to the increase of anxiety frequency in hearing-impaired children. Conclusion: Childhood hearing impairment exhibits a substantial impact on children's and parental mental health, which is further exacerbated by the COVID-19 pandemic. Families of hearing-impaired children appear to be in a vulnerable position during public health emergencies such as the COVID-19 pandemic, which can further exacerbate their mental outcomes.

Mendelian randomization analysis reveals causality of inflammatory bowel disease on risks of Henoch-Schönlein purpura and immune thrombocytopenia.

BACKGROUND: Emerging clinical evidence has been discovered associating Inflammatory bowel disease (IBD) with Henoch-Schönlein purpura (HSP) and immune thrombocytopenia (ITP). However, it is unclear whether a cause-effect relationship exists between them. We aimed to examine the casual effect of IBD on the risk of HSP and ITP. METHODS: Based on summary statistics from International IBD Genetics (IIBDG) Consortium and FinnGen study, a two-sample Mendelian randomization study was carried out to determine whether IBD including ulcerative colitis (UC) and Crohn's disease (CD) is causally related to HSP, ITP or secondary thrombocytopenia. To support the results, a variety of sensitivity analyses were performed. RESULTS: Significant causal relationships between IBD and HSP (odds ratios = 1.20, 95% confidence interval: 1.07-1.36, adjusted P = 0.006) and ITP (odds ratios =1.22, 95% confidence interval: 1.08-1.38, adjusted P = 0.006) were found. Both genetically predicted UC and CD were positively related with ITP, while CD alone may be responsible for the higher risk of HSP. Besides, no significant association was observed between IBD and secondary thrombocytopenia. CONCLUSIONS: The results of this Mendelian randomization study supported the causal association of IBD with HSP and ITP. Taken together, our findings may present implications for management of IBD.

Molecular insights into the anti-spoilage effect of salicylic acid in Favorita potato processing.

Salicylic acid is a commonly used anti-spoilage agent to prevent browning and quality degradation during potato processing, yet its precise mechanism remains unclear. This study elucidates the role of StuPPO2, a functional protein in Favorita potato shreds, in relation to the anti-browning and starch degradation effects of 52 SA analogues. By employing molecular docking and Gaussian computing, SA localizes within the hydrophobic cavity of StuPPO2, facilitated by hydroxyl and carboxyl groups. The inhibitory effect depends on the distribution pattern of the maximal electrostatic surface potential, requiring hydroxyl ion potentials of >56 kcal/mol and carboxyl ion potentials of >42 kcal/mol, respectively. Multiomics analysis, corroborated by validation tests, indicates that SA synthetically suppresses activities linked to defense response, root regeneration, starch degradation, glycoalkaloids metabolism, and potato shred discoloration, thereby preserving quality. Furthermore, SA enhances antimicrobial and insect-repellent aromas, thereby countering biotic threats in potato shreds. These collective mechanisms underscore SA's anti-spoilage properties, offering theoretical foundations and potential new anti-browning agents for agricultural preservatives.

[Effect of wenxin granule on plasma BNP and HRV of acute coronary syndrome patients].

OBJECTIVE: To observe the effect of Wenxin Granule (WG) on brain natriuretic peptide (BNP) and heart rate variability (HRV) of acute coronary syndrome (ACS) patients. METHODS: Totally 65 ACS patients were randomly assigned to the treatment group (35 cases) and the control group (30 cases). All patients were treated with routine therapies such as angiotensin conversing enzyme inhibitors (ACEI) and metoprolol. Those in the treatment group took WG, 9 g each time, three times daily. All were treated for 90 days. Plasma samples of BNP and HRV were determined before treatment and after treatment. RESULTS: There was no statistical difference in pre-treatment plasma BNP (P > 0.05). Plasma BNP significantly decreased after treatment in the two groups when compared with before treatment (P < 0.05). The decrease was more obvious in the treatment group (P < 0.05). There was no statistical difference in pre-treatment HRV (P > 0.05). Compared with before treatment in the same group, RMSSD, PNN50%, and high frequency (HF) obviously increased, while low frequency (LF) and LF/HF ratio significantly decreased in the two groups, showing statistical difference (P < 0.05). The aforesaid indices were obviously better in the treatment group than in the control group (P < 0.05). CONCLUSION: Additional administration of WG could improve short-term clinical prognosis by down-regulating plasma BNP level (via improving myocardial ischemia) and modulating HRV.

Neoantigen cancer vaccines: a new star on the horizon.

Immunotherapy represents a promising strategy for cancer treatment that utilizes immune cells or drugs to activate the patient's own immune system and eliminate cancer cells. One of the most exciting advances within this field is the targeting of neoantigens, which are peptides derived from non-synonymous somatic mutations that are found exclusively within cancer cells and absent in normal cells. Although neoantigen-based therapeutic vaccines have not received approval for standard cancer treatment, early clinical trials have yielded encouraging outcomes as standalone monotherapy or when combined with checkpoint inhibitors. Progress made in high-throughput sequencing and bioinformatics have greatly facilitated the precise and efficient identification of neoantigens. Consequently, personalized neoantigen-based vaccines tailored to each patient have been developed that are capable of eliciting a robust and long-lasting immune response which effectively eliminates tumors and prevents recurrences. This review provides a concise overview consolidating the latest clinical advances in neoantigen-based therapeutic vaccines, and also discusses challenges and future perspectives for this innovative approach, particularly emphasizing the potential of neoantigen-based therapeutic vaccines to enhance clinical efficacy against advanced solid tumors.

Nanomaterial-based magnetic surface molecularly imprinted polymers for specific extraction and efficient recognition of dibutyl phthalate.

A rapid and selective sorbent for the enrichment of dibutyl phthalate (DBP) from water and Chinese Baijiu samples was established using magnetic surface molecularly imprinted polymers (MSMIPs) combined with gas chromatography-mass spectrometer (GC-MS). The MSMIPs were synthesized using a magnetic nanosphere material with silica layer, increasing the polymer surface area as a carrier. Compared with the traditional methods, the addition of magnetic microspheres simplified the process of food substrate purification and significantly shortened the pre-concentration time. The MSMIPs adsorption conforms to the Freundlich isotherm model as multilayer adsorption on an inhomogeneous surface and the pseudo-second-order model. The developed MSMIPs combined with GC-MS method showed good linearity in DBP concentration range of 0.02-1.0 mg L-1 with low LOD (0.0054 mg L-1) and LOQ (0.018 mg L-1), and obtained good recoveries in real samples (95.2-97.2%) with RSD < 5.0% (n = 9), which were consistent with those from Chinese national standard method.

[MYETS1 recombinant expression in prokaryotic cells and deletion analysis in multiple myeloma cell lines].

OBJECTIVE: To explore the down-expression mechanism of MYETS1 gene in multiple myeloma cell lines ARH-77 or KM3, and express MYETS1 gene in prokaryotic express system. METHODS: The region of chromosome 13q14.3 in ARH-77 and KM3 was detected by FISH. MYETS1 gene was amplified by RT-PCR and cloned into prokaryotic expression vector pGEX-4T. RESULTS: Positive consequence was acquired in 13q14.3 where MYETS1 located by FISH in ARH- 77 and KM3 cell lines. Bioinformatics indicated highly sequence homology between MYETS1 and LECT1, but excluded the homology of open reading frame between MYETS1 and that of LECT1 by RT-PCR. Myets1 protein was expressed and harvested successfully. CONCLUSION: The region of chromosome 13q14.3 ,where MYETS1 gene located, was not defected in ARH-77 and KM3 cell lines. Down-expression of MYETS1 might be regulated by other mechanisms in multiple myeloma cell lines.

Electrochemical sensing platform for the detection of methyl parathion applying highly biocompatible non-covalent functionalized phosphonium-based ionic liquid@MWCNTs hybrid to immobilize hemoglobin.

A hydrophobic carboxyl functionalized phosphonium-based ionic liquid (IL) ((5-carboxypentyl) triphenylphosphonium bis (trifluoromethyl)sulfonyl) amide, TPP-HA[TFSI]) was synthesized through a simple hydrothermal approach. Based on the π-π and cation-π interactions with multi-wall carbon nanotubes (MWCNTs), a TPP-HA[TFSI]@MWCNTs hybrid was prepared to immobilize hemoglobin (Hb) to fabricate a simple and effective electrochemical sensing platform for the detection of methyl parathion (MP) in vegetables. Spectroscopic and electrochemical results show that TPP-HA[TFSI]@MWCNTs substrate synergistically provided a good biocompatible microenvironment for Hb, and the hydrophobicity of TPP-HA[TFSI] and the π-π interaction and hydrogen bonding between TPP-HA[TFSI]@MWCNTs, Hb and nafion (NF) were conducive to maintain the stability and integrity of the modified electrode interface. The TPP-HA[TFSI]@MWCNTs with large surface area and high conductivity promoted the exposure of the electroactive center of Hb and the direct electron transfer between Hb and the electrode, which effectively amplified the electrochemical signal and improved the sensitivity of MP detection. The constructed electrochemical sensing platform had a wider linear range (2-14 ng mL-1) and a lower detection limit (0.62 ng mL-1) for MP, and had acceptable repeatability, reproducibility, stability and anti-interference ability. This results indicated that the phosphonium-based ILs functionalized MWCNTs was an effective substrate for the immobilization of biological components, which have broad prospect in the construction of electrochemical sensing interfaces.

A SiO2@MIP electrochemical sensor based on MWCNTs and AuNPs for highly sensitive and selective recognition and detection of dibutyl phthalate.

A molecularly imprinted sensor for highly sensitive and selective determination of dibutyl phthalate (DBP) was fabricated by combining multi-walled carbon nanotubes (MWCNTs) and Au nanoparticles (AuNPs) with surface molecularly imprinted polymer (SMIPs). The MWCNTs and AuNPs were designed to modify the electrode surface to accelerate the electron transfer rate and enhance the chemical stability. SMIPs were synthesized using SiO2 microspheres as carriers. By loading SMIPs capable of identifying DBP on the surface of modified electrodes of MWCNTs and AuNPs, an electrochemical sensor for detecting DBP was successfully constructed. After optimizing the experimental conditions, the modified electrode SiO2-COOH@MIP/AuNPs/MWCNTs/GCE can recognize DBP in the range of 10-7g L-1 to 10-2g L-1, and the detection limit achieved to 5.09 × 10-9 g L-1 (S/N = 3). The results demonstrate that the proposed MIP electrochemical sensor may be a promising candidate electrochemical strategy for detecting DBP in complex samples.

Electrochemical sensor applying ZrO2/nitrogen-doped three-dimensional porous carbon nanocomposite for efficient detection of ultra-trace Hg2+ ions.

In this study, a ZrO2/nitrogen-doped three-dimensional porous carbon (ZrO2/N-3DPC) nanocomposite was manufactured to fabricate an effective electrochemical sensor for the detection of ultra-trace mercury ion (Hg2+). The synthesized N-3DPC had an open pore structure, large specific surface area and enough continuous mass transfer channels, which can facilitate the diffusion and transmission of electrons and ions at the sensing interface, providing an effective adhesion platform for electrochemical deposition of ZrO2 nanoparticles. Benefiting from the synergistic effect of ZrO2 and N-3DPC, the developed electrochemical sensor had good adsorption and catalytic performance for Hg2+ with a wider linear range of 0.1-220 µg L-1 and a lower detection limit of 0.062 µg L-1. Meanwhile, the sensor exhibited remarkable repeatability, reproducibility, stability and anti-interference, and was further applied to detect Hg2+ in seafood and tap water with satisfactory recoveries (97.1-103.1%) and lower relative standard deviation (≤4.3%). The proposed strategy of electrochemical sensing detection of Hg2+ provides a new idea and direction for the research of ZrO2/N-3DPC nanocomposite in the field of analysis and detection, which is also of great significance to ensure foods, environmental safety and human health.

Clinical significance and prognostic value of receptor conversion after neoadjuvant chemotherapy in breast cancer patients.

The hormone receptor (HR) status and human epidermal growth hormone receptor 2 (HER2) status of patients with breast cancer may change following neoadjuvant chemotherapy (NAC). We retrospectively analyzed the clinical data of 294 patients with stage II/III breast cancer to evaluate the clinical significance and prognostic value of receptor transformation after NAC in breast cancer patients. Pathological complete response after NAC was achieved in 10.7% of patients. HR, estrogen receptor (ER), progesterone receptor (PR), HER2, and Ki-67 conversion rates were 9.2%, 6.5%, 13.0%, 4.4%, and 33.7%, respectively. Patients with stable HR (P = 0.01) and HER2 (P = 0.048) expression had more favorable overall survival (OS). Low or reduced Ki-67 expression was associated with better disease-free survival (DFS) (P < 0.001) and OS (P < 0.01). Multivariate analysis showed that the number of lymph nodes after NAC, HR conversion, and radiotherapy were independent prognostic factors for overall survival. HR conversion implied a higher risk of death [hazard ratio, 2.56 (95% confidence interval: 1.19-5.51); P = 0.016]. Patients with HR conversion after NAC who received endocrine therapy had better DFS (P = 0.674) and OS (P = 0.363) than those who did not receive endocrine therapy, even if the HR changed from positive to negative. In conclusion, pathological testing should be performed before and after NAC, and even patients with HR conversion after NAC might benefit from endocrine therapy.

Aqueous Solution-Processed Nanometer-Thin Crystalline Indium Ytterbium Oxide Thin-Film Transistors.

We demonstrate the growth of ultra-thin (~5 nm) indium ytterbium oxide (In-Yb-O) thin film using a simple vacuum-free aqueous solution approach for the first time. The influences of Yb addition on the microstructural, chemical, optical, and electrical properties of In2O3 are well investigated. The analyses indicate that Yb dopant could suppress oxygen vacancy defects effectively owing to the lower standard electrode potential, lower electronegativity, and stronger metal-oxide bond strength than that of In. The optimized In-Yb-O thin-film transistors (TFTs) exhibit excellent electrical performance (mobility of 8 cm2/Vs and on/off ratio of ~108) and enhanced stability. The triumph of In-Yb-O TFTs is owing to the high quality In2O3 matrix, the remarkable suppressor of Yb, and the nanometer-thin and atomically smooth nature (RMS: ~0.26 nm) of channel layer. Therefore, the eco-friendly water-induced ultra-thin In-Yb-O channel provides an excellent opportunity for future large-scale and cost-effective electronic applications.

Aptamer-Based Fluorescent Biosensor for the Rapid and Sensitive Detection of Allergens in Food Matrices.

Food allergies have seriously affected the life quality of some people and even endangered their lives. At present, there is still no effective cure for food allergies. Avoiding the intake of allergenic food is still the most effective way to prevent allergic diseases. Therefore, it is necessary to develop rapid, accurate, sensitive, and reliable analysis methods to detect food allergens from different sources. Aptamers are oligonucleotide sequences that can bind to a variety of targets with high specificity and selectivity, and they are often combined with different transduction technologies, thereby constructing various types of aptamer sensors. In recent years, with the development of technology and the application of new materials, the sensitivity, portability, and cost of fluorescence sensing technology have been greatly improved. Therefore, aptamer-based fluorescence sensing technology has been widely developed and applied in the specific recognition of food allergens. In this paper, the classification of major allergens and their characteristics in animal and plant foods were comprehensively reviewed, and the preparation principles and practical applications of aptamer-based fluorescence biosensors are summarized. In addition, we hope that this article can provide some strategies for the rapid and sensitive detection of allergens in food matrices.

An "Off-On" Rhodamine 6G Hydrazide-Based Output Platform for Fluorescence and Visual Dual-Mode Detection of Lead(II).

In this study, the rhodamine 6G hydrazide (R6GH) complex was synthesized to develop an "off-on" output platform for fluorescence and visual dual-mode analysis of lead(II) (Pb2+). The prepared R6GH complex using the heat to reflux reaction of rhodamine 6G (R6G) and hydrazine hydrate was characterized through FT-IR, MS, 1H NMR, and 13C NMR and demonstrated to have good fluorescence stability and reversibility. The microenvironment for Pb2+ detection has been optimized in detail. Under the optimal conditions, the "off-on" R6GH-based fluorescence output platform showed a good response to Pb2+ in the concentration range of 0.05-6.0 µM (R2 = 0.9851) with a limit of detection (LOD) of 0.02 µM. Furthermore, at three spiked Pb2+ levels in the selected agricultural (tap water, soil) and food (fish, shrimp) samples, the developed R6GH-based fluorescence assays obtained a significant recovery range of 84.0-102.0% (RSD < 5.0%, n = 3), which had a good correlation with the results from ICP-MS (R2 = 0.9915). The developed R6GH immobilized paper-based array sensor can reach the lower LOD (2.5 µM) for Pb2+ through the naked eye. By combining with LAB analysis, a good linear response was obtained in the Pb2+ concentration range of 1.0-50.0 µM. These results indicated that the developed R6GH probe had great application potential in accurate detection of fluorescence and rapid visual and semiquantitative screening for Pb2+.
