Natural variation at the cotton HIC locus increases trichome density and enhances resistance to aphids.

Plant trichomes are an excellent model for studying cell differentiation and development, providing crucial defenses against biotic and abiotic stresses. There is a well-established inverse relationship between trichome density and aphid prevalence, indicating that higher trichome density leads to reduced aphid infestations. Here we present the cloning and characterization of a dominant quantitative trait locus, HIC (hirsute cotton), which significantly enhances cotton trichome density. This enhancement leads to markedly improved resistance against cotton aphids. The HIC encodes an HD-ZIP IV transcriptional activator, crucial for trichome initiation. Overexpression of HIC leads to a substantial increase in trichome density, while knockdown of HIC results in a marked decrease in density, confirming its role in trichome regulation. We identified a variant in the HIC promoter (-810 bp A to C) that increases transcription of HIC and trichome density in hirsute cotton compared with Gossypium hirsutum cultivars with fewer or no trichomes. Interestingly, although the -810 variant in the HIC promoter is the same in G. barbadense and hirsute cotton, the presence of a copia-like retrotransposon insertion in the coding region of HIC in G. barbadense causes premature transcription termination. Further analysis revealed that HIC positively regulates trichome density by directly targeting the EXPANSIN A2 gene, which is involved in cell wall development. Taken together, our results underscore the pivotal function of HIC as a primary regulator during the initial phases of trichome formation, and its prospective utility in enhancing aphid resistance in superior cotton cultivars via selective breeding.

Antiferromagnetism and Phase Stability of CrMnFeCoNi High-Entropy Alloy.

It has long been suspected that magnetism could play a vital role in the phase stability of multicomponent high-entropy alloys. However, the nature of the magnetic order, if any, has remained elusive. Here, by using elastic and inelastic neutron scattering, we demonstrate evidence of antiferromagnetic order below ∼80 K and strong spin fluctuations persisting to room temperature in a single-phase face-centered cubic (fcc) CrMnFeCoNi high-entropy alloy. Despite the chemical complexity, the magnetic structure in CrMnFeCoNi can be described as γ-Mn-like, with the magnetic moments confined in alternating (001) planes and pointing toward the ⟨111⟩ direction. Combined with first-principles calculation results, it is shown that the antiferromagnetic order and spin fluctuations help stabilized the fcc phase in CrMnFeCoNi high-entropy alloy.

The renal histopathology of nonproteinuric kidney impairment: a three center experience.

Proteinuria is a biomarker of kidney injury that typically results from glomerular and/or tubulointerstitial disease. Whereas kidney impairment with normal urinary protein excretion is usually less focused and understudied. We conducted a retrospective review of the renal histopathology of the patients with variable degrees of unexplained renal insufficiency but with normal range proteinuria between 2014 and 2024 of  three university teaching hospitals in Shenzhen city of Southern  China. Patients with kidney dysfunction of undetermined or uncertain etiology and with normal urinary protein excretion (defined by a 24hr urinary protein excretion < 150 mg or spot urinary protein to creatinine ratio [PCR] < 150 mg/g) were enrolled and analyzed. In a total of 2405 patients, 53 (2.2%) fulfilled the inclusion criteria  (male/female 40/13, age 47.3 ± 14.3 years) with a mean eGFR of 46.6 ± 16.8 ml/min per 1.73 m2. Glomerular disease (GD) was the most frequent pathological finding identified in 23 (43.4%) patients, while 19 (35.8%) cases  showed tubulointerstitial disease (TID) and 11 (20.8%) patients exhibited small vascular disease (SVD). Patients in the TID had the lowest mean eGFR and the highest numerical 24hr urinary protein excretion among the three groups. The incidence of acute kidney injury was significantly higher in TID than in other two groups. The patients in the SVD group had the highest fraction of underlying hypertension. Kidney dysfunction with normal range proteinuria may be related with, in descending order of probablity,  glomerular, tubulointerstitial and small vascular diseases. Renal biopsies were proved useful in informing therapeutic choice, long-term management and in predicting prognosis in this setting.

The solute carrier transporters (SLCs) family in nutrient metabolism and ferroptosis.

Ferroptosis is a novel form of programmed cell death caused by damage to lipid membranes due to the accumulation of lipid peroxides in response to various stimuli, such as high levels of iron, oxidative stress, metabolic disturbance, etc. Sugar, lipid, amino acid, and iron metabolism are crucial in regulating ferroptosis. The solute carrier transporters (SLCs) family, known as the "metabolic gating" of cells, is responsible for transporting intracellular nutrients and metabolites. Recent studies have highlighted the significant role of SLCs family members in ferroptosis by controlling the transport of various nutrients. Here, we summarized the function and mechanism of SLCs in ferroptosis regulated by ion, metabolic control of nutrients, and multiple signaling pathways, with a focus on SLC-related transporters that primarily transport five significant components: glucose, amino acid, lipid, trace metal ion, and other ion. Furthermore, the potential clinical applications of targeting SLCs with ferroptosis inducers for various diseases, including tumors, are discussed. Overall, this paper delves into the novel roles of the SLCs family in ferroptosis, aiming to enhance our understanding of the regulatory mechanisms of ferroptosis and identify new therapeutic targets for clinical applications.

Trajectory patterns and factors associated with acceptance of disability in young and middle-aged breast cancer patients: a longitudinal study.

PURPOSE: To explore the trajectories of acceptance of disability in young and middle-aged breast cancer patients based on a latent class growth analysis, investigate factors associated with each trajectory, and identify whether return to normal living differs in different trajectories. METHODS: Young and middle-aged patients newly diagnosed with breast cancer who underwent surgery were followed up at baseline, and 1, 3, and 6 months in China. Participants completed sociodemographic information questionnaires, the Adaptation of Disability Scale Revised, and the Reintegration to Normal Living Index. A latent class growth analysis was used to explore the trajectories of acceptance of disability. RESULTS: Among 212 patients newly diagnosed with breast cancer, the mean age of patients was 45.44 years. The majority of participants were with invasive carcinoma (77.8%). Three classes were identified: high acceptance of disability increasing group (high-increasing, 13.7%), moderate acceptance of disability stable group (moderate-stable, 67.9%), and moderate acceptance of disability decreasing group (moderate-decreasing, 18.3%). Being unemployed or retired and receiving endocrine therapy are risk factors associated with acceptance of disability. Carcinoma in situ is a protective factor associated with acceptance of disability. Participants diagnosed with carcinoma in situ and who not receive endocrine therapy were more likely to be in high-increasing group. Unemployed participants before surgery were more likely to be in moderate-decreasing group. Moreover, the Reintegration to Normal Living Index scores had significant differences from baseline to 6 months of follow-up. The high-increasing group had the highest average Reintegration to Normal Living Index scores than the moderate-stable group and the moderate-decreasing group, showing similar patterns at four timepoints. CONCLUSION: We identified three trajectories of acceptance of disability. Dynamic and individualized intervention should be continuously provided to ensure patients acquire adequate medical resources to comprehensively increase acceptance of disability.

3-Methylthiophene: A Sustainable Solvent for High-Performance Organic Solar Cells.

The use of harmful halogenated or aromatic solvents such as chloroform (CF), chlorobenzene (CB), and o-xylene (o-XY) is one of the greatest barriers to the industrial-scale manufacturing of high-performance organic solar cells (OSCs). Therefore, it is necessary to eliminate the effects of these solvents to ensure practical feasibility of OSCs. We found that the anthracene-terminated polymer donor and small-molecule acceptor BO-4Cl had good solubility in 3-methylthiophene (3-MeT). There were no toxicity labels in the SDS and exposure control limits for 3-MeT. An overall power conversion efficiency of 16.87% was achieved by using 3-MeT as the solvent for solar cell fabrication, which was higher than that of the cells made from CF (16.18%) and o-XY (15.69%). The best OSC based on PM6:D18:L8-BO and fabricated with 3-MeT exhibited a high PCE of 18.13%, which is one of the highest values for cells fabricated from halogen-free solvents. These results indicate that 3-MeT is an eco-friendly and low-toxicity solvent for the sustainable fabrication of the OSC active layer.

Mesoporous Hollow Carbon Sphere-Embedded MXene Architectures Decorated with Ultrafine Rh Nanocrystals toward Methanol Electrooxidation.

The development of advanced Pt-alternative anode electrocatalysts with high activity and reliable stability is critical to overcoming the technical challenges of direct methanol fuel cells. Here, we propose a robust bottom-up strategy for the spatial construction of mesoporous hollow carbon sphere (HCS)-embedded MXene architectures decorated with ultrafine Rh nanocrystals (Rh/HCS-MX) via stereoscopic coassembly reactions. The rational intercalation of HCS effectively separates the MXene nanowalls to achieve a rapid mass-transfer efficiency, while the intimate coupling of the hybrid carrier with Rh nanocrystals enables their electronic structure optimization, thus contributing to strong synergistic catalytic effects. Accordingly, the resulting Rh/HCS-MX architectures exhibit outstanding methanol electrooxidation properties in terms of large electrochemical active surface areas, high mass/specific activities, and good long-term stability, all of which are significantly superior to the traditional Rh/carbon black, Rh/HCS, and Rh/MXene as well as commercial Pt/carbon balck and Pd/carbon balck electrocatalysts.

Isolation of Limosilactobacillus mucosae G01 with inhibitory effects on porcine epidemic diarrhea virus in vitro from Bama pig gastroenteritis.

Porcine epidemic diarrhea virus (PEDV) is responsible for causing fatal watery diarrhea in piglets, resulting in significant economic losses within the pig farming industry. Although vaccination is currently employed as a preventive measure, certain vaccines do not provide complete protection against PEDV field strains. Probiotics present a promising alternative due to their ability to regulate intestinal flora, enhance host immunity, and improve resistance against pathogenic microorganisms. We isolated six lactic acid bacteria (LAB) from the fecal microorganisms of Bama pigs, compared to Limosilactobacillus mucosae DSM13345 of the same genus in which Limosilactobacillus mucosae G01 (L. mucosae G01) proved to have a potent anti-PEDV effect. In a comprehensive manner, L. mucosae G01 significantly augmented the phosphorylation of IRF3 in IPEC-J2 cells, resulting in the induction of interferons (IFN α, IFN ß, IFN λ1, and IFN λ3) and subsequent upregulation of interferon-stimulated genes (ISGs) (MX1, MX2, OAS1, and ZAP) in a dose-dependent fashion, consequently leading to the mitigation of PEDV replication. These findings underscore the promising prospects of L. mucosae G01 as a naturally derived substitute for combating PEDV and other enteric coronavirus infections.

Dye-Sensitized Commercial TiO2 for the Construction of Robust Nanocoatings with the Enhanced Transmittance and Visible-Light-Activated Photocatalytic Self-Cleaning Properties.

TiO2-based nanocoatings exhibit great promise in practical applications owing to their superior photocatalytic property. However, because of the wide band gap of TiO2, its photocatalytic capacity is only limited in the ultraviolet range. Herein, we designed and constructed robust SiO2@TiO2 composite nanocoatings with improved transmittance and visible-light-activated photocatalytic self-cleaning properties. Sulfonated cobalt(II) phthalocyanine (CoPcTs) was used as an organic dye to sensitize commercial TiO2 nanoparticles (Degussa P25) to form CoPcTs-P25 for visible-light photocatalysis. CoPcTs-P25 and small-sized solid silica nanoparticles (SSNs) were utilized as two building blocks, and acid-catalyzed silica sol (ACSS) was used as a binder to fabricate the nanocoatings via a simple dip-coating method without requiring any post-processing. By tuning the mass ratios of SSNs to CoPcTs-P25, the nanocoating with the optimized property showed the highest transmittance of ca. 97.0% at the wavelength of 566 nm, higher photocatalytic activity of degrading the organic pollutants than N-TiO2-based nanocoatings, high mechanical firmness of 3H level in pencil hardness test and 4A level in tape adhesion test, and good weather resistance. In short, the dye-sensitized commercial P25 TiO2 nanoparticles should be a promising building block for low-cost and easy preparation of robust nanocoatings with enhanced transmittance and visible-light-activated photocatalytic self-cleaning properties.

Self-power, multiwavelength photodetector based on a Sn-doped Ge quantum dots/hexagonal silicon nanowire heterostructure.

Tin-doped germanium quantum dots (Sn-doped Ge QDs)-decorated hexagonal silicon nanowires (h-Si NWs) were adopted to overcome the low infrared response of silicon and the excess dark current of germanium. High-quality Sn-doped Ge QDs with a narrow bandgap can be achieved through Ge-Sn co-sputtering on silicon nanowires by reducing the contact area between heterojunction materials and Sn-induced germanium crystallization. The absorption limit of the heterostructure is extended to 2.2 µm, and it is sensitive to 375-1550 nm light at 0 V, which has optimality at 1342 nm, with a photo-to-dark current ratio of over 815, a responsivity of 0.154 A/W, and a response time of 0.93 ms. The superior performance of the Sn-doped Ge QDs/h-Si NW photodetector in multiwavelength is attractive for multi-scenario applications.

B-Cell Maturation Antigen/CD19 Dual-Targeting Immunotherapy in Newly Diagnosed Multiple Myeloma.

Importance: Patients with high-risk newly diagnosed multiple myeloma (NDMM) often have poor outcomes with standard treatments, necessitating novel effective frontline therapies to enhance clinical outcomes. GC012F, a B-cell maturation antigen/CD19 dual-targeting chimeric antigen receptor (CAR) T-cell therapy, has been developed on the novel FasTCAR platform. Notably, its use as a frontline therapy for patients with high-risk NDMM who are eligible for transplant has not been thoroughly explored. Objective: To examine the safety, pharmacokinetics, and patient health and survival outcomes associated with GC012F in individuals with NDMM. Design, Setting, and Participants: Patients were enrolled in this single-arm, open-label phase 1 cohort study between June 28, 2021, and June 1, 2023 (the data cutoff date). All patients included in this study were treated at a single center, Shanghai Changzheng Hospital. The patients in the efficacy evaluation were followed up for a minimum period of 3 months. Intervention: Patients underwent 2 cycles of induction therapy, followed by GC012F infusion (at 1 × 105 cells/kg, 2 × 105 cells/kg, or 3 × 105 cells/kg). Main Outcomes and Measures: The primary goals were to assess the safety, efficacy, and pharmacokinetics of GC012F at various dose levels. Results: Of 22 patients receiving GC012F treatment, 6 experienced mild to moderate cytokine release syndrome (grade 1-2) and none experienced neurotoxic effects. Nineteen patients were included in the efficacy evaluation, and all 19 patients showed stringent complete responses and achieved minimal residual disease negativity. The treatment's effectiveness was consistent across different dose levels. GC012F demonstrated a rapid response, with a median time to first stringent complete response of 84 days (range, 26-267 days) and achieving minimal residual disease negativity within 28 days (range, 23-135 days). The CAR T-cell expansion was robust, with a median peak copy number of 60 652 copies/µg genomic DNA (range, 8754-331 159 copies/µg genomic DNA), and the median time to median peak copy number was 10 days (range, 9-14 days). Conclusions and Relevance: The findings of this single-arm, open-label phase 1 cohort study suggest that GC012F may be a safe treatment associated with positive health and survival outcomes for patients with high-risk NDMM eligible for transplant. Owing to the small sample size, further studies with larger cohorts and longer follow-up durations are needed.

Building 3D Crosslinked Graphene-MXene Nanoarchitectures Decorated with MoS2 Quantum Dots Enables Efficient Electrocatalytic Hydrogen Evolution.

Although MoS2 quantum dots with abundant edge sites have been regarded as promising eletrode materials for the hydrogen evolution reaction (HER), their electrocatalytic capacity still requires improvements in actual applications. Herein. we demonstrate a controllable and robust bottom-up approach to build 3D crosslinked graphene-Ti3C2Tx MXene frameworks decorated with MoS2 quantum dots (MQD/RGO-MX) via a convenient co-assembly process. The novel structural design gives the MQD/RGO-MX nanoarchitectures a series of superior textural attributes, including 3D interconnected networks, continuous meso- and macropores, well-dispersed quantum dots, ameliorative electronic configuration, and excellent electrical conductivity. Accordingly, the resulting hybrid nanoarchitectures express superior electrocatalytic properties in terms of a low onset potential of only 45 mV, a small Tafel slope of 61 mV dec-1 as well as a long service life towards the HER, which make it quite competitive against bare MoS2 quantum dots, MXene as well as binary MQD/RGO and MQD/MXene electrocatalysts.

An open-label, prospective trial to evaluate the efficacy and safety of ixazomib in combination with cyclophosphamide and dexamethasone in patients with newly diagnosed POEMS syndrome.

This open-label, prospective trial evaluated the combination of ixazomib, cyclophosphamide and dexamethasone (ICD) in 12 newly diagnosed POEMS syndrome patients. The study is registered with the Chinese Clinical Trials Registry (ChiCTR2000030072). The treatment protocol consisted of 12 cycles of the ICD regimen compromising ixazomib (4 mg on Days 1, 8 and 15), oral cyclophosphamide (300 mg on Days 1, 8 and 15) and dexamethasone (20 mg weekly). A total of 12 patients received a median of 10 (range: 3-23) cycles of the ICD regimen. The haematological response could be evaluated in 10 patients. The overall haematological response rate was 80% (8/10), with 30% (3/10) achieving complete haematological response, and the overall serum VEGF response rate and neurological response were 100% and 83.3% respectively. Two patients experienced grade 3/4 AEs, including diarrhoea (n = 1) and leukopenia (n = 1). The combination of ixazomib, cyclophosphamide and dexamethasone demonstrated both efficacy and safety in newly diagnosed POEMS syndrome, making it a viable treatment option.

Inhibition of KIAA1429/HK1 axis enhances the sensitivity of liver cancer cells to sorafenib by regulating the Warburg effect.

N6-methyladenosine (m6A) serves as the most abundant posttranscription modification. However, the role of m6A in tumorigenesis and chemotherapeutic drugs sensitivity remains largely unclear. Present research focuses on the potential function of the m6A writer KIAA1429 in tumor development and sorafenib sensitivity in liver cancer. We found that the level of KIAA1429 was significantly elevated in liver cancer tissues and cells and was closely associated with poorer prognosis. Functionally, KIAA1429 promoted the proliferation and Warburg effect of liver cancer cells in vitro and in vivo. RNA-seq and MeRIP-seq analysis revealed the glycolysis was one of the most affected pathways by KIAA1429, and m6A-modified HK1 was the most likely targeted gene to regulate the Warburg effect. KIAA1429 depletion decreased Warburg effect and increased sorafenib sensitivity in liver cancer. Mechanistically, KIAA1429 could affect the m6A level of HK1 mRNA through directly binding with it. Moreover, KIAA1429 cooperated with the m6A reader HuR to enhance HK1 mRNA stability, thereby upregulating its expression. These findings demonstrated that KIAA1429/HK1 axis decreases the sensitivity of liver cancer cells to sorafenib by regulating the Warburg effect, which may provide a novel therapeutic target for liver cancer treatment.

A cross-sectional survey of first-aid kit equipment in a family in Sichuan, China.

PURPOSE: To examine residents' first-aid kit preparation and its influencing factors. DESIGN: Cross-sectional survey. METHODS: A questionnaire survey was conducted among 449 permanent residents in Sichuan Province using convenience sampling. We examined participants' demographic characteristics, self-efficacy, health literacy, and personality. FINDINGS: Of the participants, 111 (24.7%) stocked a home first-aid kit. The most frequent supplies were disinfection supplies (91.9%), common medicines (86.5%), and dressing supplies (76.6%). Family per capita monthly income, medical expenses payment method, chronic diseases, general self-efficacy, and health literacy were influencing factors of family first-aid kit preparedness. CONCLUSION: A multilevel and interactive emergency literacy education system should be established to improve residents' abilities to prevent emergencies.

Case report and brief literature review: possible association of secukinumab with Guillain-Barré syndrome in psoriasis.

The etiology of Guillain-Barré syndrome (GBS) may be autoimmune. About two-thirds of patients typically experience their first symptoms within 5 days to 3 weeks after common infectious diseases, surgery, or vaccination. Infection is a triggering factor for over 50% of patients. In recent years, a growing number of studies have indicated that some immune checkpoint inhibitors and COVID-19 may also contribute to the occurrence of GBS. However, drugs are considered a rare cause of GBS. The patient in our case was a 70-year-old man who developed GBS after initiating secukinumab for psoriasis. Upon diagnosis suggesting a potential association between secukinumab and the development of GBS, as per the Naranjo adverse drug reaction (ADR) probability scale, we decided to discontinue the drug. Following this intervention, along with the administration of immunoglobulin, the patient exhibited a significant improvement in extremity weakness. The association of GBS with secukinumab treatment, as observed in this case, appears to be uncommon. The underlying mechanisms that may link secukinumab to the development of GBS are not yet fully understood and warrant further scientific inquiry and rigorous investigation. However, we hope that this report can raise greater awareness and vigilance among medical professionals to enhance the safety of patients' medication.

Tailoring Stress-Relieved Structure for SnSe Toward High Performance Potassium Ion Batteries.

Metal chalcogenides as an ideal family of anode materials demonstrate a high theoretical specific capacity for potassium ion batteries (PIBs), but the huge volume variance and poor cyclic stability hinder their practical applications. In this study, a design of a stress self-adaptive structure with ultrafine SnSe nanoparticles embedded in carbon nanofiber (SnSe@CNF) via the electrospinning technology is presented. Such an architecture delivers a record high specific capacity (272 mAh g-1 at 50 mA g-1) and high-rate performance (125 mAh g-1 at 1 A g-1) as a PIB anode. It is decoded that the fundamental understanding for this great performance is that the ultrafine SnSe particles enhance the full utilization of the active material and achieve stress relief as the stored strain energy from cycling is insufficient to drive crack propagation and thus alleviates the intrinsic chemo-mechanical degradation of metal chalcogenides.

The trajectories of psychosocial adjustment among young to middle-aged women with breast cancer: A prospective longitudinal study.

PURPOSE: This study aims to explore heterogeneous trajectories of psychosocial adjustment among young to middle-aged women with breast cancer and determine the predictive factors influencing these trajectories. METHODS: This study was conducted from October 2019 to October 2022 across two hospitals in Guangzhou. Demographic and disease characteristics, psychosocial adjustment, self-efficacy, social support, and coping modes were collected at baseline. Follow-up evaluations of psychosocial adjustment occurred at 1, 3, and 6 months post-surgery. Latent class growth modeling identified distinct patterns of psychosocial adjustment trajectories. Logistic regression analysis determined the predictive factors. RESULTS: A total of 377 young to middle-aged women with breast cancer participated in this study, with 289 participants completing the 6-month follow-up. Three distinct trajectories of psychosocial adjustment were identified including a "sustained severe maladjustment" trajectory, comprising 22.5% of participants, a "sustained moderate maladjustment" trajectory, comprising 50.4% of participants, and a "well-adjusted class" trajectory, comprising 27.1% of participants. Predictors of psychosocial adjustment trajectories included affected side, surgical type, chemotherapy, self-efficacy, social support, and coping modes. CONCLUSIONS: This study revealed three distinct trajectories of psychosocial adjustment among young to middle-aged women with breast cancer. Those with right-sided breast cancer, undergoing total mastectomy, receiving chemotherapy, low self-efficacy, limited social support, and relying on confrontation or avoidance coping modes may experience sustained maladjustment.
