Color-neutral and reversible tissue transparency enables longitudinal deep-tissue imaging in live mice.

Light scattering in biological tissue presents a significant challenge for deep in vivo imaging. Our previous work demonstrated the ability to achieve optical transparency in live mice using intensely absorbing dye molecules, which created transparency in the red spectrum while blocking shorter-wavelength photons. In this paper, we extend this capability to achieve optical transparency across the entire visible spectrum by employing molecules with strong absorption in the ultraviolet spectrum and sharp absorption edges that rapidly decline upon entering the visible spectrum.

Promoting the butterfly transformation of residual sludge: Specific adsorption of heavy metals and in-situ cultivation of granular sludge.

To address low sludge resource utilization and high treatment costs, this study uses low-temperature hydrothermal oxidation to pretreat residual sludge, generating calcium salt sludge-induced nuclei (Ca-SC). It demonstrates Ca-SC's dual role in heavy metal adsorption and low-temperature in-situ cultivation of aerobic granular sludge (AGS) in continuous-flow systems. Hydrothermal oxidation forms a hierarchically porous mixed-crystalline structure.

A novel twin time series network for building energy consumption predicting.

Energy consumption prediction in buildings is crucial for optimizing energy management. The latest research faces three critical challenges: (1) Insufficient temporal correlation extraction and prediction accuracy, hindering widespread adoption and application; (2) The positive impact of timestamp embedding in time series prediction under multi-mode decomposition; and (3) The issue of adaptive coupling with multi-source data. To overcome these issues, the study proposes Twin Time-Series Networks (T2SNET), which incorporates a time-embedding layer and a Temporal Convolutional Network (TCN) to extract patterns from Complete Ensemble Empirical Mode Decomposition with Adaptive Noise (CEEMDAN), along with an adaptive fusion gate to combine energy consumption and meteorological data.

Single-Cell RNA Sequencing Delineates the Atlas and Cell Interactions of the Testicular Cells in Chinese Soft-Shelled Turtle (Pelodiscus sinensis).

For further investigations on male germ cells' development and differentiation in Chinese soft-shelled turtle (Pelodiscus sinensis), it is crucial to define testicular cell types and their molecular regulators. Here, the 10 × Genomics single-cell RNA sequencing was adopted to study the transcriptomic profiles of single cells during the spermatogenesis of adult Chinese soft-shelled turtle.

Metformin and Dietary Restriction Counteract Aging via Reducing m6A-Dependent Stabilization of Methionine Synthase mRNA in Brachionus asplanchnoidis (Rotifera).

Metformin, a medication primarily used to treat diabetes, has gained attentions for its potential antiaging properties. Although the metabolic and cellular pathways behind its longevity effects have been widely studied, few studies have explored the epigenetic regulatory effects of metformin, which are a crucial factor in aging processes. In this study, we examined the antiaging effects of metformin using the Brachionus rotifer as a model, focusing on the regulation of mRNA N6-methyladenosine (m6A), a key RNA modification involved in mRNA stability, translation, and splicing.

In this study, the life-history parameters, transcriptomic regulation, multi-generational offspring size, and population dynamics of rotifers were determined in response to BTBPE (0, 0.01, 1, and 100 μg/L).

Achieving transient and reversible optical transparency in live mice with tartrazine.

Optical imaging provides real-time visualization of tissues and cells at high spatial and temporal resolutions through techniques such as fluorescence microscopy, optical coherence tomography and photoacoustic imaging. However, overcoming light scattering, caused by mismatches in the refractive indices of tissue components such as water and lipids, still represents a major challenge, particularly when imaging through the thicker biological tissues of living animals. Despite advances in deep-tissue imaging, many optical methods struggle to achieve diffraction-limited resolution at depth or are unsuitable for use in live animals.

Nuclear receptor coactive 4-mediated ferritinophagy: a key role of heavy metals toxicity.

Nuclear receptor coactive 4 (NCOA4) is a specific receptor for ferritinophagy, transporting ferritin to lysosomal degradation, releasing free iron, and excessive iron levels may lead to cellular redox imbalance, contributing to cell death, predominantly ferroptosis. NCOA4 is regulated by a variety of transcriptional, post-transcriptional, translational, and post-translational modifications. Targeted modulation of NCOA4-mediated ferritinophagy has been successfully used as a therapeutic strategy in several disease models.
