Then, we investigated their expression in five other A. actinomycetemcomitans strains grown in general and CS-containing media. The expression pattern of virulence factors varied among strains. Compared with the other five strains, HK1561 showed high expression of omp29 regardless of the CS addition, while the gene expression of leukotoxin in HK1651 was higher only in the medium without CS. HK1651 showed reduced biofilm in both CS- and saliva-containing media. Coaggregation with Fusobacterium nucleatum was remarkably enhanced using HK1651 grown in the CS-containing medium. Our results indicate that the expression of virulence factors is altered by adaptation to different conditions during infection.The construction of hydrophobic nanochannel with hydrophilic sites for bionic devices to proximally mimick real bio-system is still challenging. Taking the advantages of MOF chemistry, a highly oriented CuTCPP thin film has been successfully reconstructed with ultra-thin nanosheets to produce abundant two-dimensional interstitial hydrophobic nanochannels with hydrophilic sites. Different from the classical active-layer material with proton transport in bulk, CuTCPP thin film represents a new type of active-layer with proton transport in nanochannel for bionic proton field-effect transistor (H+ -FETs). The resultant device can reversibly modulate the proton transport by varying the voltage on its gate electrode. check details Meanwhile, it shows the highest proton mobility of ≈9.5×10-3  cm2  V-1  s-1 and highest on-off ratio of 4.1 among all of the reported H+ -FETs. Our result demonstrates a powerful material design strategy for proximally mimicking the structure and properties of bio-systems and constructing bionic electrical devices.

The aim of our study was to estimate the association of ficolin-1 (FCN1) gene (rs10120023, rs1071583) and ficolin-3 (FCN3) gene (rs3813800, rs10794501) polymorphisms and pulmonary tuberculosis (PTB) susceptibility, as well as their several clinical features, in a Chinese population.

This study included a cohort of 489 PTB patients and 489 healthy controls, and the four SNPs were genotyped by improved multiple ligase detection reaction (iMLDR).

We found that there were no significant differences regarding the allele and genotype frequencies of FCN1 rs10120023, rs1071583 and FCN3 rs3813800, rs10794501 between PTB patients and healthy controls (all p>0.05). The association of three main haplotypes (CC, CT, and TC) in FCN1 and three main haplotypes (CT, GA, and GT) in FCN3 with PTB susceptibility was also analyzed, and no significant association was detected (all p>0.05). In FCN1, the rs1071583TT genotype was significantly associated with the occurrence of drug resistance in PTB patients (p=0.040). In addition, the GG genotype and G allele frequencies of rs3813800 in FCN3 gene were significantly higher in PTB patients with pulmonary infection (p=0.027, p=0.020, respectively).

FCN1 and FCN3 genetic variation were not contributed to the pathogenesis of PTB in Chinese. While rs1071583 and rs3813800 variant might associate with several clinical characteristics of PTB.

To explore the experiences of being discharged from hospital of older patients with chronic diseases at time of discharge.

Multi-centre descriptive qualitative study.

Semi-structured interviews were conducted with older patients with chronic diseases discharged from two Italian university hospitals, between March 2017 and October 2019. The interviews were audio-recorded, transcribed verbatim and analysed using inductive content analysis. Several strategies were used to ensure the credibility, dependability, confirmability, authenticity and transferability of the findings. The study was reported in accordance with Standards for Reporting Qualitative Research and Consolidated criteria for reporting qualitative research.

Sixty-five patients participated in the study. Six main categories emerged feelings, need for information, time of fragility, need for support, need for trusting relationships, and home as a caring place.

Older patients with chronic diseases are patients who require quality discharge pmanage their chronic condition at home.

Discharge from hospital remains an area of concern as older people have varying degrees of met and unmet needs during and following hospital discharge. Discharge is characterized by conflicting feelings of patients, who need information and support of healthcare professionals through trusting and continuous relationships. Understanding the experience of discharge is essential to support older patients with chronic diseases, considering that discharge from hospital is not an end point of care but a stage of the process involving care transition. The reframing of discharge as another transition point is crucial for healthcare professionals, who will be responsible for making their patients fit for discharge by preparing them to manage their chronic condition at home.

Inactivation of Cys

ATPase 2 (SERCA2) causes intracellular Ca

accumulation, which activates calcineurin-mediated nuclear factor of activated T-lymphocytes (NFAT)/NF-κB pathways, and results in the phenotypic modulation of smooth muscle cells (SMCs) to accelerate angiotensin II-induced aortic aneurysms. Our goal was to investigate the mechanism involved.

We used heterozygous SERCA2 C674S knock-in (SKI) mice, where half of C674 was substituted by serine, to mimic partial irreversible oxidation of C674. The aortas of SKI mice and their littermate wild-type mice were collected for RNA sequencing, cell culture, protein expression, luciferase activity and aortic aneurysm analysis.

Inactivation of C674 inhibited the promoter activity and protein expression of PPARγ, which could be reversed by inhibitors of calcineurin or NF-κB. In SKI SMCs, inhibition of NF-κB by pyrrolidinedithiocarbamic acid (PDTC) or overexpression of PPARγ2 reversed the protein expression of SMC phenotypic modulation markers and inhibited cell proliferation, migration, and macrophage adhesion to SMCs.
