Changes in critical sites of virus-encoded protein or cis-acting element generally determine pathogenicity differentiation among different isolates of the same plant virus. Cucumber mosaic virus (CMV) isolates, which exhibit the most extensively known host range, demonstrate notable pathogenicity differentiation. This study focuses on the severe isolate CMV and mild isolate CMV, both affecting several species within the Solanaceae family, to identify the key factors regulating pathogenicity differentiation.

Background: Colorectal cancer (CRC), the third most common cancer worldwide, has increasingly detrimental effects on human health. Radiotherapy resistance diminishes treatment efficacy. Studies suggest that spermine synthase (SMS) may serve as a potential target to enhance the radiosensitivity.

Article Synopsis
  • Apple Valsa canker disease, caused by Valsa mali, threatens apple tree growth, and this study explores the role of specific MAPK signaling pathway components (VmMkh1, VmMkk1, and VmSpm1) in this process.
  • Deletion of these components slows growth, reduces the production and germination of conidia, and hampers survival under stress conditions (like high salinity and cell wall disruptors).
  • The research indicates that these components are crucial in regulating various aspects like growth, stress response, and pathogenicity associated with Valsa mali.

Lytic polysaccharide monooxygenases (LPMOs) of auxiliary activity family 9 (AA9) oxidatively degrade cellulose. Cellulose is degraded by cellulases via hydrolysis in the termite gut. However, it remains uncertain whether oxidative cleavage of cellulose occurs within the termite gut.

Synthetic polypeptides, also known as poly(α-amino acids), have the same polyamide backbone structures as natural proteins and peptides. As an important class of biomaterials, polypeptides have been widely used because of their biocompatibility, bioactivity and biodegradability. Ring-opening polymerization of N-carboxyanhydride (NCA) is a classical and widely used method for the synthesis of polypeptides.

Apple Valsa canker disease, caused by Valsa mali Miyabe et Yamada, severely endangers the healthy growth of apple trees. The Som1, located downstream of the cyclic AMP-dependent protein kinase A (cAMP-PKA) pathway, plays crucial roles in the growth, development, morphological differentiation, and virulence of filamentous fungi. In this study, we identify and functionally characterize VmSom1, a homolog of Som1, in Valsa mali.

Polypeptides have the same or similar backbone structures as proteins and peptides, rendering them as suitable and important biomaterials. Amino acid -carboxyanhydrides (NCA) ring-opening polymerization has been the most efficient strategy for polypeptide preparation, with continuous advance in the design of initiators, catalysts and reaction conditions. This Perspective first summarizes the recent progress of NCA synthesis and purification.

Multidrug resistance is the main obstacle to cancer chemotherapy. Overexpression of drug efflux pumps causes excessive drug efflux from cancer cells, ultimately leading to drug resistance. Hereby, we raise an effective strategy to overcome multidrug resistance using a synergistic combination of membranolytic antitumor β-peptide polymer and chemotherapy drugs.

Drug-resistant fungal infections pose a significant threat to human health. Dual-targeting compounds, which have multiple targets on a single pathogen, offer an effective approach to combat drug-resistant pathogens, although ensuring potent activity and high selectivity remains a challenge. Here we propose a dual-targeting strategy for designing antifungal compounds.

Article Synopsis
  • Cardiac contractility modulation (CCM) is a new therapy for heart failure patients, specifically those with reduced ejection fraction (HFrEF), showing benefits like improved exercise tolerance and quality of life.
  • * This report highlights a unique case where CCM was used in conjunction with left bundle branch pacing cardiac resynchronization therapy (LBBP CRT-P) in a woman with a long history of non-ischemic dilated cardiomyopathy.
  • * Despite initial recovery with medical treatments and CRT, the patient’s quality of life worsened, and heart transplantation wasn't an option due to costs and advanced heart failure stage; this case represents a first for both the region and the combination therapy in China.*

Invasive fungal infections, including meningitis, cause a high mortality rate due to few available antifungal drugs and frequently associated side effects and quick emergence of drug-resistant fungi. The restrictive permeability of the blood-brain barrier (BBB) further limits the efficacy of antifungal agents substantially in treating meningitis. Hereby, we design and synthesize guanidinium-functionalized poly(2-oxazoline)s by mimicking cell-penetrating peptides.

Background: Previous studies have shown that sepsis is implicated in a reduction in the number and function of CD4 T cells. TCF7 and LEF-1 facilitate early T cell development and lineage selection of CD4 T cells. However, the function and mechanism of TCF7 and LEF-1 in sepsis are uncharacterized.

The infections associated with implantable medical devices can greatly affect the therapeutic effect and impose a heavy financial burden. Therefore, it is of great significance to develop antimicrobial biomaterials for the prevention and mitigation of healthcare-associated infections. Here, a facile construction of antimicrobial surface via one-step co-deposition of peptide polymer and dopamine is reported.

Introduction: This study endeavored to investigate the role of DOCK8 in modulating the immune function triggered by sepsis.

Methods: Expression of DOCK8 in the whole blood of sepsis patients and its enrichment pathways were assayed by bioinformatics. Pearson analysis was used to predict the relationship between glycolytic signaling pathway and its relevance to neutrophil function in sepsis.

Bupirimate is widely used as a highly active systemic fungicide. However, the frequent and heavy use of bupirimate has led to pesticide residues in crops that threaten human health and food safety. At present, there is limited research on the detection of ethirimol, which is the metabolite of bupirimate.

Pesticide residue has become the main technical barrier that restricts the export of Chinese wolfberry. Can we achieve high efficacy and low safety risk by balancing pesticide deposition on the leaves and fruits of Chinese wolfberry? In this research, the structural characteristics and wettability of leaves and fruits of Chinese wolfberry at different growth stages were studied. The adaxial and abaxial surfaces of leaves were hydrophobic, whereas the fruit surfaces were hydrophilic.

Objective: To analyze independent risk factors for postoperative venous thromboembolism (VTE) in patients after thoracoscopic lobectomy and establish a risk model for predicting thrombosis.

Methods: We selected 135 patients who underwent thoracoscopic lobectomy and assigned them to a VTE group ( = 31) and a non-VTE group ( = 104) according to the presence or absence of postoperative VTE. Univariate and multivariate logistic regression models were built to identify independent risk factors for postoperative thrombosis.

Objective: Visinin-like protein 1 (VILIP-1) is a neuron-specific calcium sensor protein rapidly released into blood after mild traumatic brain injury (mTBI) and may be a suitable biomarker for identification of sports-related concussion (SRC). The objective of the study is to test if quantification of a specific post-translationally modified (ubiquitinated) form of VILIP-1 (ubVILIP-1) from a fingerstick blood sample using a point of care (POC) lateral flow device (LFD) can be used to rapidly identify athletes with SRC.

This study was carried out to demonstrate the mechanism of phenolic root exudates affecting microbial-mediated cadmium (Cd) speciation transformation thus enhancing the Avicennia marina tolerance to Cd. A rhizo-box experiment was conducted including eight treatments with four Cd levels (0, 1, 2, and 4 mg Cd kg) and two phenol levels (0, 15 mg kg). The results showed that the addition of phenols increased the pH, reduced the number of iron-reducing bacteria (IRB) and sulfur-oxidizing bacteria (SOB) in the rhizosphere sediments, meanwhile promoted the transformation of Cd to low activity speciation.
