Phosphorylation of USP27X by GSK3β maintains the stability and oncogenic functions of CBX2.

Chromobox protein homolog 2 (CBX2) exerts a multifaceted impact on the progression of aggressive cancers. The proteasome-dependent pathway is crucial for modulating CBX2 regulation, while the specific regulatory roles and mechanisms of deubiquitinating enzymes targeting CBX2 remain poorly understood. Mass spectrometry analysis identified ubiquitin-specific peptidase 27X (USP27X) as a deubiquitinating enzyme that targets CBX2.

Association of Combined Exposure to Ambient Air Pollutants, Genetic Risk, and Incident Rheumatoid Arthritis: A Prospective Cohort Study in the UK Biobank.

In this time-series analysis, we used data from two major hospitals in Hefei, collected between 2015 and 2019, to evaluate the impact of meteorological factors on the risk of herpes zoster. After controlling for confounders, we adopted a distributed lag nonlinear model to probe the relationship between meteorological factors and outpatient visits for herpes zoster.

Short-term effect of ambient temperature and ambient temperature changes on the risk of warts outpatient visits in Hefei, China: a retrospective time-series study.

Concerns are growing about the adverse health effects of ambient temperature and ambient temperature changes. However, the association between ambient temperature and ambient temperature changes on the risk of warts outpatient visits is poorly understood. Our study used the distributed lag non-linear model (DLNM) aimed to evaluate the association between ambient temperature, ambient temperature changes (including temperature change between neighboring days (TCN) and diurnal temperature range (DTR)), and warts outpatient visits.

Implementation of Fault-Tolerant Encoding Circuit Based on Stabilizer Implementation and "Flag" Bits in Steane Code.

Quantum error correction (QEC) is an effective way to overcome quantum noise and de-coherence, meanwhile the fault tolerance of the encoding circuit, syndrome measurement circuit, and logical gate realization circuit must be ensured so as to achieve reliable quantum computing. Steane code is one of the most famous codes, proposed in 1996, however, the classical encoding circuit based on stabilizer implementation is not fault-tolerant. In this paper, we propose a method to design a fault-tolerant encoding circuit for Calderbank-Shor-Steane (CSS) code based on stabilizer implementation and "flag" bits.

Short-term association of NO with hospital visits for chronic kidney disease and effect modification by temperature in Hefei, China: A time series study.

Background: A large body of evidence has linked air pollution and temperature with chronic kidney disease (CKD) prevalence and hospitalizations. However, most studies have focused on the influence of heat stress on CKD prevalence, and the potential effect modification of temperature on the association between air pollution and CKD has not been well-investigated. In this study, we examined the associations of the whole temperature spectrum and air pollution with CKD-related hospital visits and explored whether temperature modifies the short-term association of air pollution with CKD-related hospital visits.

Influence of chitosan oligosaccharide on the gelling and wound healing properties of injectable hydrogels based on carboxymethyl chitosan/alginate polyelectrolyte complexes.

In situ injectable hydrogels for wound healing based on carboxymethyl chitosan (CMCS) and alginate were developed in this work. The liquid mixture of CMCS and alginate solutions formed a gel by polyelectrolyte complexation after addition of d-glucono-δ-lactone (GDL), which slowly hydrolyzed and donated protons. When chitosan oligosaccharide (COS) was added into the mixture, a two-stage gelling process occurred.

Hygroscopicity modulation of hydrogels based on carboxymethyl chitosan/Alginate polyelectrolyte complexes and its application as pH-sensitive delivery system.

Polyelectrolyte complex (PECs) hydrogels with high hygroscopicity modulation ability were successfully prepared based on carboxymethyl chitosan (CMCS)/alginate. The swelling ratio of the hydrogels could be tuned from 1 to 450 simply by changing the weight ratio of CMCS to alginate, and superabsorbent hydrogels were obtained when the weight ratio of CMCS to alginate was below 1/1. Also, the swelling kinetics and water diffusion mechanism in the hydrogels were discussed.

Druce in response to daily flooding, a large-scale quantitative lysine acetylome was carried out using immunoaffinity enrichment of Lys-acetylated peptides and liquid chromatography linked to tandem mass spectrometry. A total of 1041 lysine acetylation (LysAc) sites, 1021 Lys-acetylated peptides and 617 Lys-acetylated proteins were identified.

Loading cisplatin onto 6-mercaptopurine covalently modified MSNS: a nanomedicine strategy to improve the outcome of cisplatin therapy.

In the treatment of cancer patients, cisplatin (CDDP) exhibits serious cardiac and renal toxicities, while classical combinations related to CDDP are unable to solve these problems and may result in worse prognosis. Alternately, this study covalently conjugated 6-mercaptopurine (6MP) onto the surface of mercapto-modified mesoporous silica nanoparticles (MSNS) to form MSNS-6MP and loaded CDDP into the holes on the surface of MSNS-6MP to form MSNS-6MP/CDDP, a tumor-targeting nano-releasing regime for CDDP and 6MP specifically. In the S180 mouse model, the anti-tumor activity and overall survival of MSNS-6MP/CDDP (50 mg·kg·day, corresponding to 1 mg·kg·day of 6MP and 5 mg·kg·day of CDDP) were significantly higher than those of CDDP alone (5 mg·kg·day) or CDDP (5 mg·kg·day) plus 6MP (1 mg·kg·day).

A multilevel investigation to discover why Kandelia candel thrives in high salinity.

The halophilic mangrove species Kandelia candel is an excellent model for understanding why halophytes thrive in high salinity. Preliminary transcriptomic analyses revealed that genes involved in diverse functions, such as in phenylpropanoid and amino acid metabolisms, and those in DNA replication and damage repair were highly responsive to salt stress. Proteomic analyses revealed that the proteins involved in light reaction of photosynthesis, amino acid and carbohydrate metabolisms, secondary metabolite biosynthesis and posttranslational modification showed increased levels in response to salt stress.

Chondrogenesis by co-culture of adipose-derived stromal cells and chondrocytes in vitro.

Adipose-derived stromal cells (ADSCs) could be induced to differentiate into chondrocytes in the presence of cellular factors. In this study, we explored the feasibility of inducing the differentiation of ADSCs into chondrocytes in the presence of chondrocytes. Human ADSCs and porcine auricular chondrocytes were expanded in vitro and then were mixed at the ratio of 7:3.

In vivo ectopic chondrogenesis of BMSCs directed by mature chondrocytes.

In vivo niche plays an important role in determining the fate of exogenously implanted stem cells. Due to the lack of a proper chondrogenic niche, stable ectopic chondrogenesis of mesenchymal stem cells (MSCs) in subcutaneous environments remains a great challenge. The clinical application of MSC-regenerated cartilage in repairing defects in subcutaneous cartilage such as nasal or auricular cartilage is thus severely limited.

Potent in vitro chondrogenesis of CD105 enriched human adipose-derived stem cells.

Adipose-derived stem cells (ASCs) are considered as a promising cell source for cartilage regeneration. However, the heterogeneity of this cell source may affect their ability in cartilage formation. It is therefore necessary to establish an efficient method for isolating the cells that have chondrogenic potential.
