Soil salinization poses a significant ecological and environmental challenge both in China and across the globe. Plant growth-promoting rhizobacteria (PGPR) enhance plants' resilience against biotic and abiotic stresses, thereby playing a vital role in soil improvement and vegetation restoration efforts. PGPR assist plants in thriving under salt stress by modifying plant physiology, enhancing nutrient absorption, and synthesizing plant hormones.

Article Synopsis
  • Tumorigenesis is influenced by numerous mutations, particularly cancer-driving nucleotides (CDNs), which are essential for understanding and treating cancer patients.
  • Despite a small number of known CDNs, the study suggests that the recurrence of advantageous mutations in a large population can help identify nearly all CDNs.
  • Identifying the complete set of CDNs would enhance our understanding of tumor evolution and improve the effectiveness of targeted therapies against cancer.

A central goal of cancer genomics is to identify, in each patient, all the cancer-driving mutations. Among them, point mutations are referred to as cancer-driving nucleotides (CDNs), which recur in cancers. The companion study shows that the probability of recurrent hits in patients would decrease exponentially with ; hence, any mutation with ≥ 3 hits in The Cancer Genome Atlas (TCGA) database is a high-probability CDN.

Article Synopsis
  • * Tea polyphenols (TPs) show promise as a potential alternative to antibiotics, demonstrating antimicrobial and anti-biofilm properties against MDRAB in lab tests and in a rat model for pulmonary inflammation.
  • * TPs were found to hinder MDRAB growth, damage its cell membrane, and interfere with biofilm formation, while also reducing lung injury and inflammation in rats, suggesting they could be effective in treating related infections from tracheal catheters.

Article Synopsis
  • - The study explores how epigenetic changes contribute to brain development and gene regulation in different types of neurons, specifically excitatory and inhibitory neurons.
  • - Researchers created epigenetic maps and found that specific histone modifications linked to neuron types are concentrated in regions known as super enhancers rich in EGR1 motifs.
  • - Results suggest that EGR1 binding in excitatory neurons primarily occurs in postnatal stages, while in inhibitory neurons, binding sites are accessible earlier in embryonic development, indicating different timing in gene regulation.

Article Synopsis
  • Hexaconazole, thifluzamide, difenoconazole, and azoxystrobin are commonly used fungicides in China to control Rhizoctonia solani, but their effectiveness in terms of resistance is not well studied.
  • Analysis of 126 R. solani isolates showed varying sensitivity levels to the fungicides, with moderate resistance to difenoconazole observed in some isolates, and resistant mutants demonstrated stable inheritance of their resistance traits.
  • The study suggests that R. solani poses a low-to-medium resistance risk to these fungicides, highlighting the importance of monitoring resistance and adjusting management strategies accordingly.

Catheter-associated urinary tract infection (CAUTI) is a prevalent type of hospital-acquired infection, affecting approximately 15% to 25% of patients with urinary catheters. Long-term use of the catheter can lead to colonization of microorganisms and biofilm formation, and may develop into bacterial CAUTI. However, the frequent replacement of catheters in clinical settings can result in tissue damage, inflammation, ulceration, and additional complications, causing discomfort and pain for patients.

Ventilator-associated pneumonia (VAP) is a common healthcare-acquired infection often arising during artificial ventilation using endotracheal intubation (ETT), which offers a platform for bacterial colonization and biofilm development. In particular, the effects of prolonged COVID-19 on the respiratory system. Herein, we developed an antimicrobial coating (FK-MEM@CMCO-CS) capable of visualizing pH changes based on bacterial infection and releasing meropenem (MEM) and FK13-a1 in a controlled manner.

Succinic acid (SA) is a valuable C4 platform chemical with diverse applications. Lignocellulosic biomass represents an abundant and renewable carbon resource for microbial production of SA. However, the presence of toxic compounds in pretreated lignocellulosic hydrolysates poses challenges to cell metabolism, leading to inefficient SA production.

Oral administration, while convenient, but complex often faces challenges due to the complexity of the digestive environment. In this study, we developed a nanoliposome (NLP) encapsulating psoralen (P) and coated it with chitosan (CH) and pectin (PT) to formulate PT/CH-P-NLPs. PT/CH-P-NLPs exhibit good biocompatibility, superior to liposomes loaded with psoralen and free psoralen alone.

Persistent foot odor and itchiness are common symptoms of tinea pedis, significantly disrupting the daily life of those affected. The cuticular barrier at the site of the tinea pedis is thickened, which impedes the effective penetration of antifungal agents. Additionally, fungi can migrate from the skin surface to deeper tissues, posing challenges in the current clinical treatment for tinea pedis.

  • Actinidia arguta is a widely distributed species known for its small, smooth fruit, rapid softening, and strong cold tolerance, distinguished from the cultivated Actinidia chinensis.
  • Researchers created a detailed genome assembly of A. arguta, which is 2.77 Gb long and organized into 116 pseudo-chromosomes, revealing two distinct geographic groups based on evolutionary divergences.
  • The study identified three key genes that contribute to fruit softening and explored the genetic basis of traits related to sexual dimorphism, providing a foundation for future research and agricultural enhancement of this species.

Strong evidence has indicated that upregulation of chemokine (CC motif) ligand-2 (CCL2) expression and the presence of an inflammatory tumor microenvironment significantly contribute to the migratory and invasive properties of oral squamous cell carcinoma, specifically oral tongue squamous cell carcinoma (OTSCC). However, the precise epigenetic mechanism responsible for enhanced CCL2 expression in response to the inflammatory mediator tumor necrosis factor alpha (TNF-α) in OTSCC remains inadequately elucidated. We have demonstrated that the production of CCL2 can be induced by TNF-α, and this induction is mediated by the chromatin remodel protein BRG1.

Light and temperature are key factors influencing the accumulation of anthocyanin in fruit crops. To assess the effects of fruit bagging during development and high post-ripening temperature on 'Hongyang' kiwifruit, we compared the pigmentation phenotypes and expression levels of anthocyanin-related genes between bagged and unbagged treatments, and between 25 °C and 37 °C postharvest storage temperatures. Both the bagging and 25 °C treatments showed better pigmentation phenotypes with higher anthocyanin concentrations.

Dental implants make it possible to replace teeth in more sophisticated ways. Nevertheless, peri-implantitis is one of the leading causes of implant failure, which can be avoided with proper soft tissue sealing. The aim of this study was to achieve the promotion of the synthesis of peri-implant epithelial hemidesmosome through Histatin 1 and porcine small intestinal submucosa (SIS) hydrogel to form a good peri-implant seal.

Introduction: Frailty is a clinical syndrome characterised by a reduced ability to adapt to external stressors owing to a reduced physiological reserve, which is caused by degeneration of multiple organ systems. Frailty is particularly prevalent among patients with hip fractures. Research on frailty in China started late; thus, evidence regarding the prevalence of frailty among older patients with hip fracture in China is scarce.
