Transcription elongation, especially RNA polymerase II (Pol II) pause-release, is less studied than transcription initiation in regulating gene expression during meiosis. It is also unclear how transcription elongation interplays with transcription initiation. Here, we show that depletion of NKAPL, a testis-specific protein distantly related to RNA splicing factors, causes male infertility in mice by blocking the meiotic exit and downregulating haploid genes.

The emission of N lasing at 391 nm from 800 nm femtosecond laser filament in air at 1 atm presents significant challenges due to the quenching effect induced by oxygen molecules. We introduce a simple technique for the 391 nm N lasing emission induced by a corona electric field-assisted femtosecond filament in air. This technique greatly addresses the challenge of exciting a 391 nm lasing from 800 nm femtosecond laser filament in air at 1 atm.

The cardioprotective effects of histone deacetylase (HDAC) inhibitors (HDIs) are at odds with the deleterious effects of HDAC depletion. Here, we use HDAC3 as a prototype HDAC to address this contradiction. We show that adult-onset cardiac-specific depletion of HDAC3 in mice causes cardiac hypertrophy and contractile dysfunction on a high-fat diet (HFD), excluding developmental disruption as a major reason for the contradiction.

To prevent the overaggressive treatment of axillary lymph nodes (ALNs) in breast cancer, it is necessary to develop a convenient analysis method that accurately and comprehensively reflects whether ALNs are metastatic or nonmetastatic. We retrospectively analyzed data from patients who underwent surgery for breast cancer at the Weifang Hospital of Traditional Chinese Medicine between January 2019 and June 2023. Binary logistic regression analysis was used to predict the metastasis status of ALNs.

The optical absorption properties of biological tissues in photoacoustic (PA) tomography are typically quantified by inverting acoustic measurements. Conventional approaches to solving the inverse problem of forward optical models often involve iterative optimization. However, these methods are hindered by several challenges, including high computational demands, the need for regularization, and sensitivity to both the accuracy of the forward model and the completeness of the measurement data.

Article Synopsis
  • The Vitamin D Antenatal Asthma Reduction Trial (VDAART) studied children from 6 months to 8 years and found links between specific gene variants and children's body mass index.
  • These associations also connected microbiome characteristics tied to obesity with important lipids and amino acids.
  • The findings suggest that genetic factors play a role in influencing the microbiome during development and highlight potential biomarkers for childhood obesity and related health issues like insulin resistance and type 2 diabetes.

  • N-phenyl-phthalamic acid (PPA) is a new plant growth regulator popular in China for fruit trees and crops, requiring study of its behavior in plants to understand environmental risks.
  • In experiments with pepper and wheat, PPA was quickly absorbed by roots and showed rapid movement to stems and leaves, reaching peak concentrations within 10 hours, especially in roots.
  • PPA was found to accumulate more in the upper leaves and was easily broken down within the plant, suggesting it can be safely applied with minimal risk to food safety.

Atrial fibrillation leads to severe diseases such as heart failure and strokes. While catheter ablation is prevalent for the treatment, existing techniques hardly can achieve both tissue selectivity and ablation uniformity. Here, we propose a bioinspired strategy for balloon-based pulsed field ablation (PFA) systems based on "flounder" electrodes.

  • The study focuses on understanding the knowledge, attitudes, and practices (KAP) of family caregivers of gastric cancer patients post-gastrectomy regarding dietary management, highlighting their strong need for nutrition knowledge.
  • The study involved 508 caregivers, mostly female and aged 40-60, with a significant number showing poor knowledge (45%) and practices (40%), although attitudes towards dietary management were largely positive (99%).
  • Analysis revealed weak correlations between knowledge and attitudes and practice, with better attitudes linked to better practices, while factors like age and duration of caregiving negatively affected practice scores.

This paper reports a compact fiber optical electric field (E-field) sensor aiming for the precise detection of transient E-field distributions. Here, a reflective polarization-reciprocal optical path is proposed, which inherently mitigates the temperature-induced birefringence interference of the electro-optical crystal without the need for additional optical elements, thereby facilitating a reduced-size sensing probe. Furthermore, an adaptive particle swarm optimization (A-PSO) algorithm has been utilized for the first time to optimize the insulation structure of the optical E-field sensor, which significantly suppresses field distortion within the sensing region by 50%.

Background: At the end of 2021, an epidemic of reproductive abnormalities in cows occurred in Jilin Province, China, posing an urgent need for a rapid diagnosis.

Results: To identify the cause of the disease, a total of 172 samples were collected from 21 dead calves and 45 aborting or pregnant cows in 10 farms across the province. Routine PCR or RT-PCR detection did not find any common abortion-related agents.

An efficient "on-off-on" electrochemiluminescence (ECL) aptasensor utilizing dual-mechanism quenching was constructed for detecting furanyl fentanyl (FuF). The first signal "on" state was achieved by novel dual-ligand zinc metal-organic frameworks (Zn-MOFs), which were synthesized by self-assembly reaction using zinc atom clusters as metal nodes, achieving strong and stable ECL emission. The "off" state was realized by the energy and electron quenching effect of copper-doped WO.

Photoacoustic (PA) and optical coherence tomography (OCT) imaging are complementary imaging modalities with distinct contrast mechanisms, penetration depths, and spatial resolutions. Integrating these two modalities into a dual-modal PA-OCT imaging system enables the simultaneous acquisition of multimodal signals within a single scan. This integration supports quantitative reconstruction of tissue characteristics, offering a more precise and comprehensive analysis than single-modal imaging.

Resonance energy transfer (RET) quenching is significantly important for developing electrochemiluminescence (ECL) sensors, but RET platforms face challenges like interference from other fluorescent substances and reliance on energy transfer efficiency. This study used Zn-PTC, formed by zinc ions coordinated with perylene-3,4,9,10-tetracarboxylate, as a dual-mechanism quencher to reduce the ECL intensity of carbon nitride nanosheets (Tg-CNNSs). CoO/NiCoO acts as a coreaction promoter, enhancing and stabilizing the luminescence of Tg-CNNSs.

Clostridioides difficile infection (CDI) is a major cause of healthcare- and antibiotic-associated diarrhea. While fecal microbiota transplantation (FMT) shows promise for recurrent CDI, its mechanisms and long-term safety are not fully understood. Live biotherapeutic products (LBPs) using pre-defined bacterial consortia offer an alternative option, but the rational designing LBPs remains challenging.

The interface properties and thermal stability of bismuth (Bi) contacts on molybdenum disulfide (MoS) shed light on their behavior under various deposition conditions and temperatures. The examination involves extensive techniques including X-ray photoelectron spectroscopy, scanning tunneling microscopy (STM), and scanning tunneling spectroscopy (STS). Bi contacts formed a van der Waals interface on MoS regardless of deposition conditions, such as ultrahigh vacuum (UHV, 3 × 10 mbar) and high vacuum (HV, 4 × 10 mbar), while the oxidation on MoS has been observed.
