A preserved transseptal puncture zone in a novel PFO occluder enables safe repeat left atrial interventions: preclinical validation in a porcine model.

Background: Conventional nickel-titanium patent foramen ovale (PFO) occluders hinder transseptal puncture due to septal obstruction, limiting access for left-heart interventions. To address this, we developed a modified PFO occluder with a designated puncturable zone.

Methods: An artificial PFO model was created in six pigs by puncturing and dilating the fossa ovalis.

A conserved Phytophthora apoplastic trypsin-like serine protease targets the receptor-like kinase BAK1 to dampen plant immunity.

Perception of microbial pathogens by plant cell-surface pattern recognition receptors (PRRs) activates pattern-triggered immunity (PTI) in plants. The receptor-like kinase BAK1 functions as co-receptor of many PRRs and is a central immune regulator in PTI signal transduction. However, the molecular mechanism by which microbial pathogens manipulate BAK1 in the apoplast to overcome this layer of immunity remains largely unknown.

Background: Septic shock-associated acute kidney injury (SS-AKI) is a severe complication with high mortality. This study aimed to investigate the risk factors associated with AKI in patients with septic shock and establish a nomogram to predict its occurrence. Methods: Patients with septic shock were categorized based on the development of AKI.

Alternaria solani Effector AsCEP20, Essential for Virulence, Targets Potato StFtsH4 Protein to Suppress Plant Disease Resistance.

Alternaria solani is an important necrotrophic pathogen causing potato early blight. However, the pathogenic molecular mechanisms of A. solani remain unclear.

Specific selection on XEG1 and XLP1 genes correlates with host range and adaptability in Phytophthora.

In diverse Phytophthora-plant pathosystems, Phytophthora secretes XLP1 (PsXEG1-Like Protein), a non-enzymatic paralog that functions as a decoy to protect XEG1 (Xyloglucan-specific Endoglucanase) from host inhibitors. Here, we show that the genus-specific selection pressures on the XEG1/XLP1 gene pair are crucial for host adaptation and are closely linked to Phytophthora host range. Our findings reveal that the XEG1/XLP1 gene pair originated within Phytophthora and subsequently evolved into genus-specific genes, undergoing functional divergence driven by preferential selection.

Global discovery, expression pattern, and regulatory role of miRNA-like RNAs in infecting the Asian honeybee larvae.

, a specialized fungal pathogen, causes lethal infection in honeybee larvae. miRNA-like small RNAs (milRNAs) are fungal small non-coding RNAs similar to miRNAs, which have been shown to regulate fungal hyphal growth, spore formation, and pathogenesis. Based on the transcriptome data, differentially expressed miRNA-like RNAs (DEmilRNAs) in infecting the worker 4-, 5-, and 6-day-old larvae (Aa-4, Aa-5, and Aa-6) were screened and subjected to trend analysis, followed by target prediction and annotation as well as investigation of regulatory networks, with a focus on sub-networks relative to MAPK signaling pathway, glycerolipid metabolism, superoxide dismutase, and enzymes related to chitin synthesis and degradation.

Smooth Muscle Silent Information Regulator 1 Contributes to Colitis in Mice.

Smooth muscle cells (SMCs) are an essential component of the intestine, play an important role to maintain intestine structure, and produce peristaltic and segmentation movements. The silent information regulator 1 (SIRT1) has a dual role along with possible mechanisms in the different experimental models of inflammatory bowel disease (IBD). However, very little is known about other putative roles that overexpression of SIRT1 in SMCs may have.

WTAP-Mediated N6-Methyladenosine Modification Promotes Gastric Cancer Progression by Regulating MAP2K6 Expression.

Wilms tumor 1 associated protein (WTAP) is a key RNA N6-methyladenosine (mA) methylase, which is involved in gastric cancer (GC) development, but its pathogenic mechanism is not clear. This study aims to thoroughly explore the underlying molecular mechanism of WTAP-mediated mA modification in GC pathogenesis. qRT-PCR and immunohistochemistry showed that significantly elevated WTAP expression in GC tissues and is related to advanced age, poorly differentiation, lymph node metastasis and high TNM stage.

Extensive influence of microsporidian infection on sucrose solution consumption, antioxidant enzyme activity, cell structure, and lifespan of Asian honeybees.

is the original host of ceranae, a widespread fungal parasite that causes bee nosemosis, which severely threatens the health of bee colonies and the sustainable development of the apiculture industry. To evaluate the impact of infection on workers, spores were purified and used to inoculate newly emerged workers to evaluate the effects of infection. This was followed by an in-depth investigation of spore load and host sucrose solution consumption.

Dual activation of soybean resistance against Phytophthora sojae by pectin lyase and degraded pectin oligosaccharides.

Phytophthora pathogens secrete numerous apoplastic effectors to manipulate host immunity. Herein, we identified a polysaccharide lyase 1 protein, PsPL1, which acts as an essential virulence factor of P. sojae infection in soybean.

Gut microbiome and metabolites mediate the benefits of caloric restriction in mice after acute kidney injury.

The role of gut microbiome in acute kidney injury (AKI) is increasing recognized. Caloric restriction (CR) has been shown to enhance the resistance to ischemia/reperfusion injury to the kidneys in rodents. Nonetheless, it is unknown whether intestinal microbiota mediated CR protection against ischemic/reperfusion-induced injury (IRI) in the kidneys.

Profiling of Phakopsora pachyrhizi transcriptome revealed co-expressed virulence effectors as prospective RNA interference targets for soybean rust management.

Soybean rust (SBR), caused by an obligate biotrophic pathogen Phakopsora pachyrhizi, is a devastating disease of soybean worldwide. However, the mechanisms underlying plant invasion by P. pachyrhizi are poorly understood, which hinders the development of effective control strategies for SBR.

Rh(I)/Sulfoxide-Imine-Olefin Complex Catalyzed Enantioselective Allylic Alkylation of 2-Fluoromalonate: Synthesis of Chiral α-Fluorolactone Bearing Vicinal Stereogenic Centers.

Highly enantioselective Rh-catalyzed allylic substitution of the racemic branched allylic substrates with 2-fluoromalonate was realized enabled by a novel chiral sulfoxide-imine-olefin ligand under mild reaction conditions. The utilization of CuSO is beneficial for improving the enantioselectivity. Notably, the chiral fluoro-containing allyl products can be employed in a selective cyclic esterification to form chiral α-fluorolactone bearing vicinal stereogenic centers.
