Targeting NKAα1 to treat Parkinson's disease through inhibition of mitophagy-dependent ferroptosis.

Dysfunction of the Na/K-ATPase (NKA) has been documented in various neurodegenerative diseases, yet the specific role of NKAα1 in Parkinson's disease (PD) remains incompletely understood. In this investigation, we utilized NKAα1 haploinsufficiency (NKAα1) mice to probe the influence of NKAα1 on dopaminergic (DA) neurodegeneration induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). Our findings reveal that NKAα1 mice displayed a heightened loss of DA neurons and more pronounced motor dysfunction compared to the control group when exposed to MPTP.

According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017.

Magnetic recyclable heterogeneous catalyst FeO/g-CN for tetracycline hydrochloride degradation via photo-Fenton process under visible light.

Antibiotic pollution of water resources is a global problem, and the development of new treatments for destroying antibiotics in water is a priority research. We successfully manufactured recyclable magnetic FeO/g-CN through the electrostatic self-assembly method. Selecting tetracycline (TC) as the target pollutant, using FeO/g-CN and HO developed a heterogeneous optical Fenton system to remove TC under visible light.

Decreased expression of serum semaphorin 3B is associated with poor prognosis of patients with hepatocellular carcinoma.

Semaphorin 3B (SEMA-3B), which belongs to the semaphorin family, has an important role in cell apoptosis and inhibition of angiogenesis. A previous study by our group revealed that SEMA-3B was downregulated in tumor tissues of patients with hepatocellular carcinoma (HCC) and exerts anti-motility and anti-invasion effects on tumor cells. However, the serum levels of SEMA-3B and their clinical significance have remained elusive; therefore, the aim of the present study was to monitor its expression in HCC and investigate its clinical significance.

Association between IL-1β and recurrence after the first epileptic seizure in ischemic stroke patients.

To analyze the association of IL-1β with recurrence after the first epileptic seizure in ischemic stroke patients and evaluate its predictive value. 238 patients with the first epileptic seizure after ischemic stroke were included in this study. IL-1β expression levels were detected through quantitative Real-Time PCR.

Sevoflurane attenuates brain damage through inhibiting autophagy and apoptosis in cerebral ischemia‑reperfusion rats.

The present study aimed to investigate the effects of sevoflurane post‑conditioning in a rat brain cerebral ischemia‑reperfusion (I/R) model and examine its possible mechanism. Rats were randomly divided into six groups: Sham control group (Sham), I/R group, sevoflurane group (Se), Toll‑like receptor‑4 (TLR4) inhibitor group (Tak‑242), nuclear factor (NF)‑κB inhibitor group (QNZ) and Sevoflurane post‑conditioning combined with TLR4‑NF‑κB signaling pathway inhibitor group (Se + Tak‑242). Morris water maze test and tetrazolium chloride staining were used to investigate the I/R injury.

Short-term outcomes of extremely preterm infants at discharge: a multicenter study from Guangdong province during 2008-2017.

Construction of a synthetic dragline silk gene multimer and its expression in .

One of the most representative core gene sequence of dragline silk protein partial cDNA monomer (JN857964.2) was selected and multimerized using a "head-to-tail" strategy by compatible but nonregenerable sites at both ends resulting in a concatemer of 16 contiguous monomers. This concatemer was cloned into pET-28a(+) expression vector and transformed into .

The effect of gamma sterilization on the insecticidal toxicity of engineered and conventional Bacillus thuringiensis strains.

This study evaluates the effect of gamma radiation on the spore activity, toxicity, and crystal structures of two engineered Bacillus thuringiensis (Bt) strains, TnX and TnY, and the reference Bt strain HD-1. We attempted to identify dosages of cobalt-60 gamma radiation that would inactivate Bt spores but not affect its toxicity. In the radiation dosage range of 10-15 kilogray, no viable spore formation and no significant reduction of the efficiency of Bt against lepidopteran larvae were observed.
