Ensuring rational application and improving utilization rates of agrochemicals are major demands in developing green delivery systems. Herein, a model of nucleic acid-peptide coacervate (NPC) for agrochemical delivery is presented, which is formed by mixing negatively charged single-stranded DNAs with positively charged poly-L-lysine.

siRNA-AGO2 complex inhibits bacterial gene translation: A promising therapeutic strategy for superbug infection.

Silencing resistance genes of pathogenic bacteria by RNA interference (RNAi) is a potential strategy to fight antibiotic-resistant bacterial infections. Currently, RNAi cannot be achieved in bacteria due to the lack of RNA-induced silencing complex machinery and the difficulty of small interfering RNA (siRNA) delivery. Here, we show that exosomal siRNAs can be efficiently delivered into bacterial cells and can silence target genes primarily through translational repression without mRNA degradation.

Immune-neuroendocrine reactivity and features of tuberculosis in pregnancy.

The combination of tuberculosis and pregnancy always raises questions about therapy, the specialness of management of pregnancy, obstetrics, postpartum period, and lactation; the effect of therapy on fetal development and the peculiarities of the tuberculosis course. Until recently, tuberculosis and pregnancy were considered a rare combination, but with the growing problem of HIV infection and worsening tuberculosis screening among adults, this combination has become quite common. Moreover, cases of congenital tuberculosis in newborns have begun to emerge.

Nonlinear differential interference contrast imaging.

Differential interference contrast (DIC) imaging is essential in both biological research and medical diagnostics. Despite considerable progress in theoretical and experimental frameworks, limited by the inefficient cameras, achieving direct DIC imaging with infrared (IR) illumination remains a formidable challenge. However, infrared DIC imaging is urgent for diverse fields.

Polarized topological invariance frequency conversion on high-fidelity information transfer.

A cross-band information converter, which links communication and storage modules operating at different wavelengths, is crucial for the development of optical vortex-based information networks. However, due to nonlinear efficiency dependence on orbital angular momentum (OAM), the traditional intensity or polarization distribution-based recognition distortion emerges. Here, by employing the optical vector vortex with a tailored polarization mode as the information carrier of communication network, and the polarization topology one-to-one mapping as the mode identification method, we demonstrate a simple yet flexible frequency converter based on sum-frequency generation (SFG) that preserves the topological invariance of polarization, enabling high-fidelity information transmission.

Autoimmune Diseases and Molecular Mimicry in Tuberculosis.

Unlabelled: Comorbidities in tuberculosis patients are increasing annually. Autoimmune pathology may influence the diagnosis and treatment of tuberculosis (TB). However, the molecular mimicry between (Mtb) and human autoantigens is an important provocative factor in the development of autoimmunity on one hand.

The Shu complex is an ATPase that regulates Rad51 filaments during homologous recombination in the DNA damage response.

Rad51 filaments are Rad51-coated single-stranded DNA and essential in homologous recombination (HR). The yeast Shu complex (Shu) is a conserved regulator of homologous recombination, working through its modulation on Rad51 filaments to direct HR-associated DNA damage response. However, the biochemical properties of Shu remain unclear, which hinders molecular insights into Shu's role in HR and the DNA damage response.

Robust unrolled network for lensless imaging with enhanced resistance to model mismatch and noise.

Lensless imaging has gained popularity in various applications due to its user-friendly nature, cost-effectiveness, and compact design. However, achieving high-quality image reconstruction within this framework remains a significant challenge. Lensless imaging measurements are associated with distinct point spread functions (PSFs), resulting in many PSFs introducing artifacts into the underlying physical model.

Multiomics and single-cell sequencings reveal the specific biological characteristics of low Ki-67 triple-negative breast cancer.

Background: Triple-negative breast cancer (TNBC) displays high heterogeneity. The majority of TNBC cases are characterized by high Ki-67 expression. TNBC with low Ki-67 expression accounts for only a small fraction of cases and has been relatively less studied.

Targeting SNRNP200-induced splicing dysregulation offers an immunotherapy opportunity for glycolytic triple-negative breast cancer.

Metabolic dysregulation is prominent in triple-negative breast cancer (TNBC), yet therapeutic strategies targeting cancer metabolism are limited. Here, utilizing multiomics data from our TNBC cohort (n = 465), we demonstrated widespread splicing deregulation and increased spliceosome abundance in the glycolytic TNBC subtype. We identified SNRNP200 as a crucial mediator of glucose-driven metabolic reprogramming.

Chitosan-based hydrogel incorporated with polydopamine and protoporphyrin for photothermal-oxidation sterilization of bacteria-infected wound therapy.

Phototherapy has emerged as a potential treatment strategy for bacteria-infected wounds, but the inadequate bacteria-capturing ability and excessive damage to normal tissues from single phototherapy are huge limitations. To solve the issues, herein we report the design of chitosan-based hydrogel with bacteria capturing and combined photothermal/photodynamic sterilization functions. Such hydrogel is prepared by mixing chitosan (CS) as matrix, protoporphyrin (PpIX) as photosensitizer and polydopamine (PDA) as photothermal agent and then chemically cross-linking CS with glutaraldehyde.

Parameter identification of Johnson-Cook constitutive model based on genetic algorithm and simulation analysis for 304 stainless steel.

Addressing the significant discrepancy between actual experimental cutting force and its predicted values derived from traditional constitutive model parameter identification methods, a reverse identification research of the Johnson-Cook (J-C) constitutive model for 304 stainless steel was conducted via genetic algorithm. Considering actual cutting zone and the influence of feed motion on the rake (flank) angle, an unequal division shear zone model was established to implement the theoretical calculation for shear zone stress. Through cutting experiments, the spindle speed was negatively correlated with the cutting force at first, and then became positively correlated; The empirical formula (EXP model) for turning force was corrected, revealing that the EXP model was unable to provide optimal predicted values for cutting force.

Oropharyngeal microbiome profiling and its association with age and heart failure in the elderly population from the northernmost province of China.

Respiratory tract infections are the most common triggers for heart failure in elderly people. The healthy respiratory commensal microbiota can prevent invasion by infectious pathogens and decrease the risk of respiratory tract infections. However, upper respiratory tract (URT) microbiome in the elderly is not well understood.

An arteriovenous fistula model: Carotid artery-posterior facial vein fistula in rats.

Objective: To describe an alternative arteriovenous fistula (AVF) model involving anastomosis of the common carotid artery (CCA) with the posterior facial vein (PFV).

Methods: Twenty-two male Sprague-Dawley rats (age 6-8 weeks) were used to establish the AVF model involving end-to-side anastomosis of PFV and CCA. The peak velocity of the CCA and the diameter of the outflow vein were recorded at 7, 14, and 42 days after the operation using Doppler ultrasound.

Decreased AMPK/SIRT1/PDK4 induced by androgen excess inhibits human endometrial stromal cell decidualization in PCOS.

Polycystic ovary syndrome (PCOS) is a complex common endocrine disorder affecting women of reproductive age. Ovulatory dysfunction is recognized as a primary infertile factor, however, even when ovulation is medically induced and restored, PCOS patients continue to experience reduced cumulative pregnancy rates and a higher spontaneous miscarriage rate. Hyperandrogenism, a hallmark feature of PCOS, affects ovarian folliculogenesis, endometrial receptivity, and the establishment and maintenance of pregnancy.

Loss-Assisted Anomalous Hong-Ou-Mandel Interference Based on Nonunitary Multilayer Graphene.

Hong-Ou-Mandel interference is an intrinsic quantum phenomenon that goes beyond the possibilities of classical physics, and enables numerous applications in quantum information science. While the photon-photon interaction is fundamentally limited to the bosonic nature of photons and the restricted phase responses from commonly used unitary optical elements, we present that a nonunitary material provides an alternative degree of freedom to control the two-photon quantum interference, even revealing anomalous quantum interference paths that do not exist in a unitary configuration. An elaborate lossy multilayer graphene that can work as a nonunitary beam splitter is used to explore its tunability over the effective photon-photon interaction in spatial modes, and to verify the particle exchange statistics by its experimental implementation in quantum state filter.

A Fast Survival Support Vector Regression Approach to Large Scale Credit Scoring via Safe Screening.

Survival models have found wider and wider applications in credit scoring recently due to their ability to estimate the dynamics of risk over time. In this research, we propose a Buckley-James safe sample screening support vector regression (BJS4VR) algorithm to model large-scale survival data by combing the Buckley-James transformation and support vector regression. Different from previous support vector regression survival models, censored samples here are imputed using a censoring unbiased Buckley-James estimator.
