A phosphodiesterase CpdB in Yersinia pseudotuberculosis degrades CDNs to inhibit innate immune response.

Yersinia pseudotuberculosis (Yptb) is a pathogenic gram-negative bacterium that can colonize the intestines of different animals. Its infection leads to the activation of the host's innate immunity. Both host and bacterial-derived cyclic dinucleotides (CDNs) could activate the innate immune response of host cells.

Classical and novel properties of Holliday junction resolvase SynRuvC from sp. PCC6803.

Cyanobacteria, which have a photoautotrophic lifestyle, are threatened by ultraviolet solar rays and the reactive oxygen species generated during photosynthesis. They can adapt to environmental conditions primarily because of their DNA damage response and repair mechanisms, notably an efficient homologous recombination repair system. However, research on double-strand break (DSB) repair pathways, including the Holliday junction (HJ) resolution process, in sp.

Functional versatility of Zur in metal homeostasis, motility, biofilm formation, and stress resistance in .

Unlabelled: Zur (zinc uptake regulator) is a significant member of the Fur (ferric uptake regulator) superfamily, which is widely distributed in bacteria. Zur plays crucial roles in zinc homeostasis and influences cell development and environmental adaptation in various species. is a Gram-negative enteric that pathogen usually serves as a model organism in pathogenicity studies.

Pseudomonas aeruginosa outer membrane vesicle-packed sRNAs can enter host cells and regulate innate immune responses.

Bacterial outer membrane vesicles (OMVs) can package and deliver virulence factors into host cells, which is an important mechanism mediating host-pathogen interactions. It has been reported that small RNAs (sRNAs) can be packed into OMVs with varying relative abundance, which might affect the function and/or stability of host mRNAs. In this study, we used OptiPrep density gradient ultra-high-speed centrifugation to purify OMVs from Pseudomonas aeruginosa.

Salmonella T3SS-elicited inflammatory innate immune response inhibits type I IFN response in macrophages.

As a gram-negative intracellular bacterial pathogen, Salmonella enterica serovar Typhimurium (S. Typhimurium) invades different cell types including macrophages. Its infection in macrophages induces robust innate immune responses that are featured by proinflammatory and type I interferon (IFN) responses.

Causal associations between hand grip strength and pulmonary function: a two-sample Mendelian randomization study.

Background: Several observational studies have reported an association between hand grip strength (HGS) and pulmonary function (PF). However, causality is unclear. To investigate whether HGS and PF are causally associated, we performed Mendelian randomization (MR) analyses.

Isolation and Characterization of Three Pseudomonas aeruginosa Viruses with Therapeutic Potential.

As one of the most common pathogens of opportunistic and hospital-acquired infections, Pseudomonas aeruginosa is associated with resistance to diverse antibiotics, which represents a significant challenge to current treatment modalities. Phage therapy is considered a promising alternative to conventional antimicrobials. The characterization and isolation of new bacteriophages and the concurrent evaluation of their therapeutic potential are fundamental for phage therapy.

Manganese potentiates lipopolysaccharide-induced innate immune responses and septic shock.

Divalent metal ions such as magnesium (Mg), manganese (Mn), and zinc (Zn) play important roles in regulating innate immune responses. Lipopolysaccharide stimulation led to increased intracellular Mn and Zn in macrophages. However, the effect of those metal ions in regulating lipopolysaccharide-induced innate immune responses remains unclear.

Salmonella Induces the cGAS-STING-Dependent Type I Interferon Response in Murine Macrophages by Triggering mtDNA Release.

Salmonella enterica serovar Typhimurium ( Typhimurium) elicited strong innate immune responses in macrophages. To activate innate immunity, pattern recognition receptors (PRRs) in host cells can recognize highly conserved pathogen-associated molecular patterns (PAMPs). Here, we showed that Typhimurium induced a robust type I interferon (IFN) response in murine macrophages.

[Clinical application of self-made minimally invasive hood-assisted transforaminal lumbar interbody fusion via modified bilateral Wiltse approach in the treatment of lumbar degenerative diseases].

Objective: To explore the advantages of self made minimally invasive hook assisted transforaminal lumbar interbody fusion (TLIF) via modified bilateral Wiltse approach in the treatment of lumbar degenerative diseases.

Methods: The clinical data of 140 patients underwent lumbar spine fusion surgery from October 2016 to October 2017 were retrospectively analyzed. Among them, 72 cases were treated by self-made minimally invasive hook-assisted TLIF via modified bilateral Wiltse approach (group A), there were 37 males and 35 females, aged (48±16) years old;68 cases were treated by TLIF via traditional posterior median approach (group B ), there were 38 males and 30 females, aged (45±15) years old.

[Vesselplasty for the treatment of spinal metastases complicated by posterior wall destruction of vertebral body].

Objective: To evaluate the early clinical efficacy and safety of vesselplasty for the treatment of spinal metastases complicated by posterior wall destruction of vertebral body.
