Sphingosylphosphorylcholine alleviates pressure overload-induced myocardial remodeling in mice via inhibiting CaM-JNK/p38 signaling pathway.

Apoptosis plays a critical role in the development of heart failure, and sphingosylphosphorylcholine (SPC) is a bioactive sphingolipid naturally occurring in blood plasma. Some studies have shown that SPC inhibits hypoxia-induced apoptosis in myofibroblasts, the crucial non-muscle cells in the heart. Calmodulin (CaM) is a known SPC receptor.

Loss of USP22 alleviates cardiac hypertrophy induced by pressure overload through HiF1-α-TAK1 signaling pathway.

Ubiquitin-specific protease 22 (USP22) is a member of the ubiquitin specific protease family (ubiquitin-specific protease, USPs), the largest subfamily of deubiquitinating enzymes, and plays an important role in the treatment of tumors. USP22 is also expressed in the heart. However, the role of USP22 in heart disease remains unclear.

Parkin-mediated mitophagy protects against TNF-α-induced stress in bone marrow mesenchymal stem cells.

Bone marrow mesenchymal stem cells (BMSCs) have been investigated as cellular therapeutics for intervertebral disc degeneration. However, transplanted BMSCs are prone to be damaged. TNF-α is reported to extensively promote degeneration process.

Multiparameter MRI Radiomics Model Predicts Preoperative Peritoneal Carcinomatosis in Ovarian Cancer.

Objectives: To evaluate the predictive value of radiomics features based on multiparameter magnetic resonance imaging (MP-MRI) for peritoneal carcinomatosis (PC) in patients with ovarian cancer (OC).

Methods: A total of 86 patients with epithelial OC were included in this retrospective study. All patients underwent FS-T2WI, DWI, and DCE-MRI scans, followed by total hysterectomy plus omentectomy.

Long non-coding RNA HOXA-AS3 facilitates the malignancy in colorectal cancer by miR-4319/SPNS2 axis.

Growing evidence has shown the oncogenic role of long non-coding RNA HOXA-AS3 in the progression of several types of cancers, while the effect of HOXA-AS3 on colorectal cancer (CRC) remains unclear. In this study, HOXA-AS3 was significantly over-expressed in CRC clinical samples and human CRC cell lines (SW480, SW620, HCT116, COLO205, and LOVO). HOXA-AS3 knockdown was further achieved by specific siRNAs in COLO205 and LOVO cell lines.

Osteoclast-mediated biocorrosion of pure titanium in an inflammatory microenvironment.

Titanium (Ti) and alloys thereof are commonly utilized in biomedical settings owing to their desirable mechanical properties and good biocompatibility. However, when exposed to biological systems for extended periods of time, Ti still undergoes corrosion. In the present study, we therefore explore the impact of osteoclasts (OC) on the surface characteristics and corrosion of commercially pure Titanium (cpTi) in the context of lipopolysaccharide (LPS)-induced inflammation.

Role of the Hippo-YAP/NF-κB signaling pathway crosstalk in regulating biological behaviors of macrophages under titanium ion exposure.

The presence of metal ions, such as titanium (Ti) ions, is toxic to adjacent tissues of implants. Indeed, Ti ions may induce an inflammatory response through the NF-κB pathway, thus causing damage to soft and hard tissues. The involvement of Yes-associated protein (YAP), a key factor of the Hippo pathway, in an immuno-inflammatory response has been confirmed, whereas its role in Ti ion-mediated inflammation has not been elucidated.

Biocorrosion of pure and SLA titanium surfaces in the presence of and its effects on osteoblast behavior.

: The study aims to investigate the biocorrosion behavior of on pure and SLA titanium surfaces and its effects on surface characteristics and osteoblast behavior. : Pure and SLA titanium specimens were immersed in culture medium with and incubated for 7 days. colonization on the pure and SLA titanium surfaces was observed by scanning electron microscopy (SEM).

Mitophagy is a protective response against oxidative damage in bone marrow mesenchymal stem cells.

Aims: Bone marrow mesenchymal stem cells (BMSCs) show great potential in clinical applications such as in intervertebral disc degeneration. Nevertheless, environmental stress during the BMSC transplant or in the injured tissues is a catastrophic factor that causes cell toxicity and poor survival of BMSCs. Mitophagy plays a vital role in maintaining cellular homeostasis and defending against oxidative stress because this process could control mitochondrial quality and quantity by eliminating dysfunctional or damaged mitochondria that can cause cell death.

Enhanced corrosion resistance of zinc-containing nanowires-modified titanium surface under exposure to oxidizing microenvironment.

Titanium (Ti) and its alloys as bio-implants have excellent biocompatibilities and osteogenic properties after modification of chemical composition and topography via various methods. The corrosion resistance of these modified materials is of great importance for changing oral system, while few researches have reported this point. Recently, oxidative corrosion induced by cellular metabolites has been well concerned.

Inhibits Hyphal Development and Diminishes Host Vaginal Mucosal TH17 Response.

and often co-colonize the female genital tract, and under certain conditions induce mucosal inflammation. The role of the interaction between the two organisms in candidal vaginitis is not known. In this study, we found that co-infection with significantly attenuated the hyphal development of , and that -Hwp1 signal pathway of was involved in this process.

Association between donor and recipient Interleukin-18 gene polymorphisms and the risk of infection after liver transplantation.

Purpose: The purpose of this study was to retrospectively evaluate the association between Interleukin-18 (IL-18) gene polymorphisms of the donor and recipient in liver transplant patients with bacterial infections.

Methods: Five single nucleotide polymorphisms (SNPs) (rs7106524, rs5744247, rs1946518, rs549908 and rs187238) of the IL-18 gene from the donors were genotyped and their association with post-operative bacterial infections was evaluated in liver transplant patients (N=113). A second independent group of liver transplant patients from a different organ transplant centre was also recruited for validation purposes (N=44).

Decreased expression of follicular dendritic cell-secreted protein correlates with increased immunoglobulin A production in the tonsils of individuals with immunoglobulin A nephropathy.

Immunoglobulin A nephropathy (IgAN) is characterized by a qualitative abnormality of IgA in the circulation and IgA deposition in the renal mesangium. Recent research has indicated that pathogenic IgA may originate from affected tonsils. Follicular dendritic cell-secreted protein (FDC-SP), a small novel secretory protein that may regulate the induction of B-cell responses, has been suggested to control IgA production.

Self-surface assembly of cellulosomes with two miniscaffoldins on Saccharomyces cerevisiae for cellulosic ethanol production.

Yeast to directly convert cellulose and, especially, the microcrystalline cellulose into bioethanol, was engineered through display of minicellulosomes on the cell surface of Saccharomyces cerevisiae. The construction and cell surface attachment of cellulosomes were accomplished with two individual miniscaffoldins to increase the display level. All of the cellulases including a celCCA (endoglucanase), a celCCE (cellobiohydrolase), and a Ccel_2454 (β-glucosidase) were cloned from Clostridium cellulolyticum, ensuring the thermal compatibility between cellulose hydrolysis and yeast fermentation.
