Aristolochic acid IVa ameliorates arthritis in SKG Mice by regulating macrophage polarization and Th17/Treg balance.

Background: Aristolochic acids (AAs)-containing herbs have been used as medicinal remedies for thousands of years. However, exposure to AAI and AAII increases the risk of nephropathy and cancers. Our previous study identified AAIVa, an analogue without carcinogenicity or nephrotoxicity, exerted anti-inflammatory effects.

Abundant geographical divergence of Clostridioides difficile infection in China: a prospective multicenter cross-sectional study.

Clostridioides difficile is the predominant pathogen in hospital-acquired infections and antibiotic-associated diarrhea. Dedicated networks and annual reports for C. difficile surveillance have been established in Europe and North America, however the extensive investigation on the prevalence of C.

A novel prostate cancer-specific fluorescent probe based on extracellular vesicles targeting STEAP1 applied in fluorescence guided surgery.

Radical prostatectomy with pelvic lymph node dissection is the best treatment for intermediate- to high-risk localized prostate cancer (PCa). However, conventional white light surgery has difficulties in identifying tumor boundary and micrometastases intraoperatively. Fluorescence guided surgery (FGS) can solve the above difficulties, but lacks tumor-specific near-infrared fluorescent (NIRF) probes in PCa.

Relaxin-2 improves type I diabetes mellitus-induced erectile dysfunction in rats by protecting cavernous endothelial and smooth muscle function, and inhibiting penile fibrosis and apoptosis.

Background: Diabetes mellitus-induced erectile dysfunction (DMED) responds poorly to first-line treatments, necessitating the development of new therapeutic strategies. Relaxin-2 (RLX-2) plays a crucial role in protecting vascular endothelium, vasodilatation, and antifibrosis in various diseases. However, its effects and mechanisms on DMED remain unclear.

The Effect of Erythromycin in Macrolide-Resistant Bordetella pertussis: Inhibitory Effect on Growth, Toxin Expression, and Virulence.

Introduction: The macrolide-resistant Bordetella pertussis (MRBp) has appeared in Asia and has even been prevalent in China. Since the antibiotic sensitivity test is not carried out in the clinical setting, macrolide is still the first choice of antibiotic in MRBp infection. Further, the macrolide therapy for pertussis needs to be revised.

Synthesis and characterization of the trans- and cis-isomers of N-acetyl-S-(4-hydroxy-2-buten-1-yl)-L-cysteine and their attempted detection in human urine.

1,3-Butadiene (BD) is a carcinogenic air pollutant. N-acetyl-S-(4-hydroxy-2-buten-1-yl)-L-cysteine (MHBMA3 or 4HBeMA), an urinary BD metabolite with unspecified configuration, is considered the most sensitive BD biomarker and has been used in routine biomonitoring since 2012. However, two issues remain unaddressed: why its concentrations are unusually high relative to other urinary BD biomarkers and why some authors reported no detection of the biomarker whereas other authors readily quantitated it.

Machine-learning-coined noise induces energy-saving synchrony.

Noise-induced synchronization is a pervasive phenomenon observed in a multitude of natural and engineering systems. Here, we devise a machine learning framework with the aim of devising noise controllers to achieve synchronization in diverse complex physical systems. We find the implicit energy regularization phenomenon of the formulated framework that engenders energy-saving artificial noise and we rigorously elucidate the underlying mechanism driving this phenomenon.

LncRNA lnc-SPRR2G-2 contributes to keratinocyte hyperproliferation and inflammation in psoriasis by activating the STAT3 pathway and downregulating KHSRP.

Psoriasis is a chronic inflammatory disease characterized by increased keratinocyte proliferation and local inflammation. Long noncoding RNAs (lncRNAs) play important regulatory roles in many immune-mediated diseases, including psoriasis. In this study, we aimed to investigate the role and mechanism of lnc-SPRR2G-2 (SPRR2G) in M5-treated psoriatic keratinocytes.

Open versus robot-assisted retroperitoneal tumors resection involving inferior vena cava, abdominal aorta, and renal hilum: a comparative study.

Introduction: Surgery is currently the only effective treatment for retroperitoneal tumors that do not involve any specific organ. The use of robots for removing both benign and malignant retroperitoneal tumors is considered safe and feasible. However, there is insufficient evidence to determine whether robotic retroperitoneal tumor resection (RMBRs) is superior to open retroperitoneal malignant resection (OMBRs).

Crystal-Site Engineering of Novel NaKMg(PO)(BO):Eu Phosphors for Full-Spectrum Lighting.

The "cyan gap" is the bottleneck problem in violet-driven full-spectrum white-light-emitting diodes (wLEDs) in healthy lighting. Accordingly, we develop a novel broadband-blue-cyan emission NaKMg(PO)(BO):Eu (NKMPB:Eu) phosphor via crystal-site engineering. This phosphor is derived from the NaKMg(PO):Eu phosphor, which shows desired abundant cyan emissive components.

[Mendelian randomization of diabetes and prostate cancer risk in East Asian population].

Objective: Mendelian randomization (MR) was used to explore the causal relationship between diabetes (type 1 and type 2) and prostate cancer (PCa) in East Asian population.

Methods: Mendelian randomization is a causal inference method based on genetic variation, which uses the influence of randomly assigned genotypes in nature on phenotype to infer the impact of biological factors on diseases. This study used genetic variation genes related to inflammatory biomarkers as instrumental variables to improve inference, and patient data was obtained from the GWAS database's aggregated association results.

Deep learning model for the detection of prostate cancer and classification of clinically significant disease using multiparametric MRI in comparison to PI-RADs score.

Background: The Prostate Imaging Reporting and Data System (PI-RADS) is an established reporting scheme for multiparametric magnetic resonance imaging (mpMRI) to distinguish clinically significant prostate cancer (csPCa). Deep learning (DL) holds great potential for automating csPCa classification on mpMRI.

Method: To compare the performance between a DL algorithm and PI-RADS categorization in PCa detection and csPCa classification, we included 1,729 consecutive patients who underwent radical prostatectomy or biopsy in Tongji hospital.

Application of next-generation sequencing in the detection of low-abundance mutations.

Mutation accumulation in somatic cells contributes to cancer development, aging and many non-malignant diseases. The true mutation frequency in normal cells is extremely low, which presents a challenge in detecting these mutations at such low frequencies. The emergence of next-generation sequencing (NGS) technology enables direct detection of rare mutations across the entire genome of any species.

Desynchronizing oscillators coupled in multi-cluster networks through adaptively controlling partial networks.

This article introduces an adaptive control scheme with a feedback delay, specifically designed for controlling partial networks, to achieve desynchronization in a coupled network with two or multiple clusters. The proposed scheme's effectiveness is validated through several representative examples of coupled neuronal networks with two interconnected clusters. The efficacy of this scheme is attributed to the rigorous and numerical analyses on the corresponding transcendental characteristic equation, which includes time delay and other network parameters.

PIG-A gene mutation as a mutagenicity biomarker among coke oven workers.

PIG-A gene mutations can be detected in humans, and PIG-A assays can potentially predict the risk of exposure to carcinogens. However, extensive, population-based studies to validate this are lacking. We studied a cohort of occupational coke oven workers with chronic high exposure to carcinogenic polycyclic aromatic hydrocarbons, which are well-studied genotoxins classified by the IARC as carcinogenic to humans.

The whole-cell proteome shows the characteristics of macrolides-resistant Bordetella pertussis in China linked to the biofilm formation.

The macrolides-resistant Bordetella pertussis (MR-Bp) isolates in China evolved from the ptxP1/fhaB3 allele and rapidly became predominant, suggestive of an adaptive transmission ability. This was different from the global prevalent ptxP3 strains, in which MR-Bp was rarely reported. The study aimed to determine the underlying mechanism responsible for fitness and resistance in these two strains.
