GABAR-PPT1 palmitoylation homeostasis controls synaptic transmission and circuitry oscillation.

The infantile neuronal ceroid lipofuscinosis, also called CLN1 disease, is a fatal neurodegenerative disease caused by mutations in the CLN1 gene encoding palmitoyl protein thioesterase 1 (PPT1). Identifying the depalmitoylation substrates of PPT1 is crucial for understanding CLN1 disease. In this study, we found that GABAR, the critical synaptic protein essential for inhibitory neurotransmission, is a substrate of PPT1.

Electrothermal desolvation-enhanced microplasma optical emission spectrometry for sensitive determination of Cd, Zn Pb and Mn in environmental water samples.

Herein, a novel electrothermal desolvation (ED) introduction approach is developed to enhance the analytical sensitivity of the point discharge (PD)-based microplasma-optical emission spectrometric (PD-MIP-OES) system for detecting trace Cd, Zn, Pb and Mn in environmental water samples. Liquid samples are converted into aerosols through a miniature ultrasonic nebulizer, and subsequently desolvated by electric heating at 350 °C. The analytes obtained after condensation (referring to the smaller apertures aerosols and volatile analytes after ED and condensation) are excited and detected by PD-MIP-OES.

Bed-immersion-ratio variation as an efficient strategy to regulate denitrification efficiency directionally in elemental sulfur packed-bed reactors.

Autotrophic denitrification in sulfur packed-bed reactors (SPBR) has been widely employed for treating municipal secondary effluent. However, the fixed volume of packed sulfur in SPBR restricts the ability to adjust denitrification efficiency in response to fluctuating influent nitrate levels, leading to either effluent standard exceedances or unnecessary sulfur consumption. Here, we proposed a novel method for directionally regulating nitrate removal efficiency (NRE) in SPBR by adjusting the bed-immersion-ratio (BIR).

Augmented machine learning for sewage quality assessment with limited data.

Physical, chemical, and biological processes within sewers significantly alter sewage composition during conveyance. This leads to the formation of sulfide and methane-compounds that contribute to sewer corrosion and greenhouse gas emissions. Reliable modeling of these compounds is essential for effective sewer management, but the development of machine learning (ML) models is hindered by differences in data accessibility and sampling frequencies of water quality variables.

Overexpression of PtNRPS1 enhances diatom-mediated bioremediation of salicylate pollution.

The accumulation of the emerging pollutant salicylic acid (SA) in the environment has gained much attention. In this study, overexpression of the non-ribosomal peptide synthase (NRPS) gene, PtNRPS1 in the marine diatom Phaeodactylum tricornutum (PtNRPS1-OE) increased resistance to SA pollutants. It was assumed that the enhanced tolerance was due to the high binding affinity between recombinant PtNRPS1 (rNRPS1) and SA pollutants.

The mediating effect of TyG-related indicators between long-term exposure to particulate matter and cardiovascular disease: evidence from a national longitudinal cohort study.

Background: Ambient particulate matter (PM) exposure is recognized as a risk factor for cardiovascular disease (CVD). However, the extent to which PM exposure is associated with CVD via triglyceride glucose (TyG)-related indicators remains unknown. This study examines the relationship between long-term PM exposure and CVD events, further assessing whether TyG-related indicators mediate this association.

Discovery of a urea-based hit compound as a novel inhibitor of transforming growth factor-β type 1 receptor: and studies.

Transforming growth factor β type 1 receptor (TGFβR1), a crucial serine-threonine kinase, is central to the TGFβ/Smad signaling pathway, governing cellular processes like growth, differentiation, apoptosis, and immune response. This pathway is closely linked to the epithelial-mesenchymal transition (EMT) process, which plays an important role in the metastasis of hepatocellular carcinoma (HCC). To date, only limited inhibitors targeting TGFβR1 have entered clinical trials, yet they encounter challenges, notably high toxicity, in clinical applications.

Ultrasound-guided modified dynamic needle tip positioning technique for distal radial artery catheterization: A randomized controlled trial.
