Reconstructing deformable soft tissues from endoscopic videos is a critical yet challenging task. Leveraging depth priors, deformable implicit neural representations have seen significant advancements in this field. However, depth priors from pre-trained depth estimation models are often coarse, and inaccurate depth supervision can severely impair the performance of these neural networks.

Ethylene is a signalling factor that plays a key role in the response of plants to abiotic stresses, such as cold stress. Recent studies have shown that the exogenous application of 1-aminocyclopropane-1-carboxylate (ACC), an ethylene promoter, affects plant cold tolerance. The cold-responsive specific gene DREB plays a crucial role in enhancing cold tolerance in plants by activating several cold-responsive (COR) genes.

Conventional wound dressings used in trauma treatment have a single function and insufficient adaptability to the wound environment, making it difficult to meet the complex demands of the healing process. Stimuli-responsive hydrogels can respond specifically to the particular environment of the wound area and realize on-demand responsive release by loading active substances, which can effectively promote wound healing. In this paper, BC/PAA-pH responsive hydrogels (BPPRHs) were prepared by graft copolymerization of acrylic acid (AA) to the end of the molecular chain of bacterial cellulose (BC) network structure.

Under salt stress, recretohalophyte Plumbago auriculata tetraploids enhance salt tolerance by increasing selective secretion of Na compared with that in diploids, although the mechanism is unclear. Using non-invasive micro-test technology, the effect of salt gland Ca content on Na and K secretion were investigated in diploid and tetraploid P. auriculata under salt stress.

Protein vesicles made from bioactive proteins have potential value in drug delivery, biocatalysis, and as artificial cells. As the proteins are produced recombinantly, the ability to precisely tune the protein sequence provides control not possible with polymeric vesicles. The tunability and biocompatibility motivated this work to develop protein vesicles using rationally designed protein building blocks to investigate how protein sequence influences vesicle self-assembly and properties.

This study aimed to confirm the ability of lignin peroxidase (LiP) and manganese peroxidase (MnP) in promoting the formation of humic substances (HS) during domesticated composting. Three raw materials with different lignin types were used for composting, including rice straw, tree branches, and pine needles. Results suggested that LiP and MnP activity increased during domesticated composting.

Enhanced secretion of Na and Cl in leaf glands and leaf vacuolar sequestration of Na or root retention of Cl, combined with K retention, contribute to the improved salt tolerance of tetraploid recretohalophyte P. auriculata. Salt stress is one of the major abiotic factors threatening plant growth and development, and polyploids generally exhibit higher salt stress resistance than diploids.

In light of a need for low-frequency, high sensitivity and broadband cardiac murmur signal detection, the present work puts forward an integrated MEMS-based heart sound sensor with a hollow concave ciliary micro-structure. The advantages of a hollow MEMS structure, in contrast to planar ciliated micro-structures, are that it reduces the ciliated mass and enhances the operating bandwidth. Meanwhile, the area of acoustic-wave reception is enlarged by the concave architecture, thereby enhancing the sensitivity at low frequencies.

Self-assembling proteins are valuable building blocks for constructing drug nanocarriers due to their self-assembly behavior, monodispersity, biocompatibility, and biodegradability. Genetic and chemical modifications allow for modular design of protein nanocarriers with effective drug encapsulation, targetability, stimuli responsiveness, and in vivo half-life. Protein nanocarriers have been developed to deliver various therapeutic molecules including small molecules, proteins, and nucleic acids with proven in vitro and in vivo efficacy.

In this work, ZIF-67 derivative CoS with diamond dodecahedron structure was firstly synthesized a series of reactions, and ZnInS@CoS heterostructures with adjustable band gaps were successfully obtained through a simple hydrothermal method. Consequently, ZnInS@CoS heterostructures have significantly enhanced visible light absorption and improved photocatalytic efficiency, among which the ZC-5 composite exhibits the highest photocatalytic hydrogen production rate up to 4261 μmol g h under simulated sunlight, to be approximately 4.8 times higher than that of pure ZnInS.

Spinach is a highly perishable product that degrades over time, including due to bacteria contaminating the product prior to packaging, yet the dynamics of bacterial spoilage and factors that affect it are not well understood. Notably, while China is the top producer of spinach globally, there is limited available microbiological data in the literature for spinach supply chains in China. The overall goal of this foundational study was to establish a baseline understanding of bacterial population dynamics on spinach from harvest to 10 days postprocessing for a Chinese supply chain that includes distribution via traditional grocery (a local physical store) and eCommerce (an online store).

Article Synopsis
  • This study investigates the impact of ionizing radiation, specifically γ-ray irradiation, on the breeding process of tulips, an important ornamental plant, aiming to accelerate the development of new varieties.
  • Results showed that low radiation doses (5 Gy) improved bulb germination and survival rates, while higher doses (20 to 100 Gy) significantly hindered seed germination, plant growth, and flower characteristics.
  • The research discovered various genetic variations in tulips through ISSR-PCR analysis, highlighting that 80 Gy may be the optimal radiation dose for enhancing mutagenic breeding efficiency in tulips.

The use of cement emulsified asphalt mortar (CA mortar) in the track structure of high-speed speed railways has been gaining considerations by many researchers due to its coupled merits of the strength of cement as well as the flexibility of asphalt material. The asphalt to cement ratio (A/C) and the compatibility among constituent materials are crucial to the properties of CA mortar. To improve the performance properties and application of CA mortar, it is imperative to have a broad understanding of the composition mechanisms and compatibility between constituent materials.

Electron beam to target turning X-ray (EBTTX) is an emerging irradiation technology that can potentially accelerate the breeding process of plants. The biological effects of EBTTX irradiation on the two freesia cultivars (the red freesia and the purple freesia) were investigated by establishing an irradiation-mediated mutation breeding protocol. The germination rate, survival rate, plant height, leaf number and area, root number and length of the two freesia cultivars decreased following different irradiation doses (25, 50, 75, and 100-Gy).

Background: High sodium intake can up-regulate the level of renal serum- and glucocorticoid-inducible kinase-1 (SGK1), which plays a pivotal role in controlling blood pressure via activation of the epithelial sodium channel (ENaC), which can lead to salt-sensitive hypertension. Increased potassium intake, or a vegetarian diet, counteracts salt-sensitive hypertension, but the underlying mechanisms are not fully understood.

Methods: Bioinformatics and molecular modeling were used to identify G-quadruplex (G4) and their conformations in the SGK1 promoter.

In recent years, with the westernization of lifestyle, reduced physical activity and increased prostate-specific antigen (PSA) testing, the incidence of prostate cancer (PCa) has risen significantly in developing countries. Currently, PSA is the only PCa biomarker applied clinically, but it does not perform well in the early diagnosis and distinguishing between benign prostatic hyperplasia and prostate cancer. With the advances in deep sequencing technology, a series of new PCa biomarkers have been recently proposed to improve the diagnostic value of PSA, such as prostate cancer antigen 3 (PCA3), TMPRSS2-ETS fusion gene, microRNA, and other regulatory non-coding RNAs.
