The transition from preclinical to clinical drug development is critically impeded by interspecies disparities, which limit the predictive validity of preclinical efficacy for human outcomes. To address this limitation, we established a human flora-associated depression rat (HFADR) model through fecal microbiota transplantation (FMT). The HFADR model bridges the preclinical-clinical translation by recapitulating conserved microbial-host interactions identified through multi-omics analysis in a chronic unpredictable mild stress (CUMS) rat model and in patients with major depressive disorder.

However, its transformation mechanisms into sensory-active compounds during tea roasting remain unclear. LC-MS-based metabolomics and multispectral analysis discovered a variety of novel color compounds (NCCs) formed from EGCG during high-temperature heating, and these compounds were positively correlated with color indexes.

This paper presents a straightforward and effective physical approach to simultaneously compensate aberration and eliminate parasitic fringes in reflective holographic microscopy. By modulating the polarization states of both the parasitic beams and the sample beam, combined with a polarized beam splitter element, parasitic fringes can be efficiently eliminated.

The MADS transcription factors SEPALLATA3 (SEP3) and APETALA1 (AP1) are essential for floral meristem development and organ identity. In Arabidopsis, SEP3 functions as a central integrator, combining MADS proteins into a tetrameric complex, with its interaction with AP1 playing a key role in sepal and petal formation.

Point mutations were introduced into specific leucine (L) amino acids within the K domain of SHORT VEGETATIVE PHASE (SVP), and their effects on the SVP-AP1 interaction were assessed. Yeast two-hybrid experiments and β-galactosidase activity assays demonstrated that SVP maintained its capacity to interact with APETALA1 (AP1) despite point mutations at the 108th, 116th, 119th, and 127th leucine residues, where leucine was substituted with alanine (A). However, the mutation of the leucine residue at position 124 to alanine abolished the interaction between SVP and AP1 regardless of whether the mutation was singular or combined with others.

Deep learning has been widely used in phase unwrapping. However, owing to the noise of the wrapped phase, errors in wrap count prediction and phase calculation can occur, making it challenging to achieve high measurement accuracy under high-noise conditions. To address this issue, a three-stage multi-task phase unwrapping method was proposed.

Ecosystem restoration has historically been viewed as an ecological endeavor, but restoration possesses significant, yet largely untapped, potential as a catalyst for personal and social transformation. We highlight the opportunity for restoration to enhance community resilience by increasing agency and collective action and countering the pervasive perception that we are powerless witnesses to environmental decline. In this perspective, we take a "bright spots" approach and highlight successful examples of ecosystem restoration that have helped to nurture a sense of place, foster optimism, and cultivate stronger and more diverse social networks.

To meet the dynamic requirement and further improve the accuracy, a two-step synchronous phase-shifting measurement system is established based on the polarization-sensitive phase modulation ability of a liquid crystal spatial light modulator; by multiplexing the reference wavefront, an accurate phase shift is generated between two independent recording channels, and a common-path self-reference vortex interference structure is built for precise spatial registration. Meanwhile, according to the speckle statistical principle, a novel two-frame phase-shifting algorithm as well as a two-step spatial registration strategy is presented to strengthen the robustness of intensity and position differences caused by spatial-multiplexing; thereby, accurate transient deformation can be directly obtained from phase-shifting speckle interferograms recorded before and after deformation.

DNA methylation is the process by which specific bases on a DNA sequence acquire methyl groups under the catalytic action of DNA methyltransferases (DNMT). Abnormal changes in the function of DNMT are important markers for cancers and other diseases; therefore, the detection of DNMT and the selection of its inhibitors are critical to biomedical research and clinical practice. DNA molecules can undergo intermolecular assembly to produce functional aggregates because of their inherently stable physical and chemical properties and unique structures.

Quantitative phase imaging (QPI) provides 3D structural and morphological information for label free living cells. Unfortunately, this quantitative phase information cannot meet doctors' diagnostic requirements of the clinical "gold standard," which displays stained cells' pathological states based on 2D color features. To make QPI results satisfy the clinical "gold standard," the virtual staining method by QPI for label free lymphocytes based on self-supervised iteration Cycle-Consistent Adversarial Networks (CycleGANs) is proposed herein.
