A fatal case of accidental asphyxia following nitrous oxide inhalation and alcohol consumption.

Nitrous oxide (NO) abuse is becoming increasingly popular worldwide. Moreover, the use of NO combined with other substances, such as alcohol, is also common. Accidental deaths associated with NO abuse are rare in forensic practice, with most fatal cases involving continuous inhalation equipment or exposure in a confined space.

Metasurface Plasmon Resonance Biosensor Enhanced with Dual Gold Nanoparticles for the Ultrasensitive Quantitative Detection of C-Reactive Protein.

The pursuit of cutting-edge diagnostic systems capable of detecting biomarkers with exceptional sensitivity and precision is crucial for the timely and accurate monitoring of inflammatory responses.

The Bi-MSPR sensor is constructed upon a nanocup array chip with gradient-free electron density, where an innovative metasurface structure is built using a PEI-immobilized dual-gold nanoparticle amplification system.

Sabatier Principle Inspired Bifunctional Alloy Interface for Stable and High-Depth Discharging Zinc Metal Anodes.

Achieving stable Zn anodes is essential for advancing high-performance Zn metal batteries. Here, we propose a Sabatier principle inspired bifunctional transition-metal (TM) interface to enable homogeneous Zn dissolution during discharging and dendrite-free Zn deposition during charging. Among various TM-coated Zn (TM@Zn) electrodes, Cu@Zn exhibits the highest reversibility and structural stability, attributed to the optimal interaction between Cu and Zn.

In Situ Analysis of Li Plating and Stripping Behaviors Under Dynamic Current Conditions for Realistic Application Scenarios.

Lithium metal batteries are considered the holy grail for next-generation high-energy systems. However, lithium anode faces poor reversibility, unsatisfying cyclability and rate capability due to its uncontrollable plating/stripping behavior. While galvanostatic conditions are extensively studied, the behavior under more realistic application scenarios with variable inputs are less explored.

Follicular fluid-derived exosomes rejuvenate ovarian aging through miR-320a-3p-mediated FOXQ1 inhibition.

Ovarian aging is mainly characterized by a progressive decline in oocyte quantity and quality, which ultimately leads to female infertility. Various therapies have been established to cope with ovarian aging, among which exosome-based therapy is considered a promising strategy that can benefit ovarian functions via multiple pathways. Here, we isolated and characterized exosomes derived from ovarian follicular fluid and profiled the differential expression patterns of noncoding exosomal RNAs in young and aged women.

Abnormal adipose tissue-derived microbes drive metabolic disorder and exacerbate postnatal growth retardation in piglet.

Postnatal growth retardation (PGR) frequently occurs during early postnatal development of piglets and induces high mortality. To date, the mechanism of PGR remains poorly understood. Adipose tissue-derived microbes have been documented to be associated with several disorders of metabolism and body growth.

High temperature ameliorates high-fat diet-induced obesity by promoting ceramide breakdown in skeletal muscle tissue.

Obesity is considered an epidemic often accompanied by insulin resistance (IR). Heat treatment (HT) has been shown to prevent high-fat diet-induced IR in skeletal muscle, but the underlying mechanisms are poorly understood. In this study, we discovered that high temperature alleviated the hallmarks of obesity by promoting glycogen synthesis and lowering blood glucose levels in skeletal muscle tissue (SMT).

Graph-based pangenome provides insights into the structural variation and genetic basis of metabolic traits in potato.

Potato is the world's most important nongrain crop. Here, we report that 29 genomes from Petota and Etuberosum sections were de novo assembled, and that 248 accessions of wild potatoes, landraces and modern cultivars were re-sequenced at > 25× depth to assess genetic diversity within the Petota section. Subsequently, a graph-based pangenome was constructed by using DM8.

Circadian rhythm disruption aggravates alveolar bone loss in rat apical periodontitis.

Background: Circadian rhythm disruption (CRD) affects the expression levels of a range of biological clock genes, such as brain and muscle ARNT-Like-1 (BMAL1), which is considered to be an important factor in triggering or exacerbating inflammatory response. However, the underlying effect of CRD on the pathogenesis of apical periodontitis, a common oral inflammatory disease, currently remains unknown. Exploring the effects and pathogenic mechanisms of CRD on apical periodontitis will be beneficial in providing new ideas for the prevention and treatment of apical periodontitis.

Kdm2a inhibition in skeletal muscle improves metabolic flexibility in obesity.

Skeletal muscle is a critical organ in maintaining homoeostasis against metabolic stress, and histone post-translational modifications are pivotal in those processes. However, the intricate nature of histone methylation in skeletal muscle and its impact on metabolic homoeostasis have yet to be elucidated. Here, we report that mitochondria-rich slow-twitch myofibers are characterized by significantly higher levels of H3K36me2 along with repressed expression of Kdm2a, an enzyme that specifically catalyses H3K36me2 demethylation.

Diagnostic value of three urine miRNAs composite score in BK virus nephropathy.

Noninvasive detection of BK virus, for early detection of BK polyomavirus-associated nephropathy post-renal transplantation, is currently an active subject of investigation. In this study, we developed and validated a novel risk score diagnostic assay (PymiR Score) based on measurements of three urine miRNAs, including BKV-related miRNA (bkv-miR-B1-5p), polyomavirus-related miRNA (bkv-miR-B1-3p) and renal tubular injury-related miRNA (miR-21-5p), by quantitative polymerase chain reaction. The limit of detection of the three miRNAs was 2 × 10 copies/mL, while the intra- and inter-assay coefficients of variation were in the ranges of 2.
