Predicting High-risk Lung Adenocarcinoma in Solid and Part-solid Nodules on Low-dose CT: A Multicenter Study.

Rationale And Objectives: High-grade patterns, visceral pleural invasion, lymphovascular invasion, spread through air spaces, and lymph node metastasis are high-risk factors and associated with poor prognosis in lung adenocarcinomas (LUADs). This study aimed to construct and validate a radiomic model and a radiographic model derived from low-dose CT (LDCT) for predicting high-risk LUADs in solid and part-solid nodules.

Materials And Methods: This study retrospectively enrolled 658 pathologically confirmed LUADs from July 2018 to December 2022 from four centers, which were divided into training set (n=411), internal validation set (n=139), and external validation set (n=108).

Chinese guidelines for minimally invasive donor hepatectomy in living donor liver transplantation (2024 edition).

Background: Minimally invasive surgeries are increasingly central to modern medicine, particularly in liver transplantation. These techniques, which offer reduced trauma, precise operations, minimal bleeding, and swift recovery, are, however, unevenly adopted across China. Only a limited number of centers routinely perform minimally invasive donor hepatectomies, indicating a significant imbalance in the development and application of these advanced procedures.

Bioprinted Symbiotic Dressings: A Lichen-Inspired Approach to Diabetic Wound Healing with Enhanced Bioactivity and Structural Integrity.

Providing oxygen and preventing infection at wound sites are effective ways to heal diabetic chronic wounds. Inspired by natural lichens, a bioprinted biogenic hydrogel (BBH) containing microalgae and probiotics is developed for diabetic chronic wound therapeutics, which offers prolonged biogenetic oxygen supply by microalgae and infection inhibition by probiotics. The rational design of symbiotic BBH with customizable structure and microorganism composition enhances wound resilience against elevated glucose levels and hypoxia, leading to the increased migration ability of fibroblasts and the angiogenic potential of human umbilical vein endothelial cells.

OMP38 of Carbapenem-Resistant Acinetobacter Baumannii-Mediated mtDNA Release Activates the cGAS-STING Signaling to Induce Inflammatory Response.

Carbapenem-resistant Acinetobacter baumannii (CRAB) has become a major threat in the treatment of bacterial infection, and immunotherapy in a non-antibiotic-dependent manner is an effective way to overcome CRAB infection. However, the role of the innate immune response in CRAB infection is poorly understood. Here, it is reported that CRAB infection induced a cytosolic DNA-sensing signaling pathway and significant IFN-β production in mice post-CRAB infection.

Pd-Catalyzed Stereospecific Glycosyl Cross-Coupling of Reversed Anomeric Stannanes for Modular Synthesis of Nonclassical -Glycosides.

Nonclassical -glycosides, distinguished by their unique glycosidic bond connection mode, represent a promising avenue for the development of carbohydrate-based drugs. However, the accessibility of nonclassical -glycosides hinders broader investigations into their structural features and modes of action. Herein, we present the first example of Pd-catalyzed stereospecific glycosylation of nonclassical anomeric stannanes with aryl or vinyl halides.

Molecular mechanisms underlying floral fragrance in 'High Fragrance': a time-course assessment.

'High Fragrance' is a camellia hybrid known for its unique and intense floral scent. The current understanding of the dynamic changes in its fragrance and the underlying mechanisms are still limited. This study employed a combination of metabolomic and transcriptomic approaches to reveal the characteristics of the metabolites involved in the remarkable fragrance of this camellia and their biosynthetic mechanisms along three flower developmental stages (flower bud, initial bloom, and full bloom).

Tardigrade Dsup: Interactions with DNA and protection of cells from oxidative stress.

The remarkable capability of Tardigrade to survive under extreme conditions has been partially attributed to Dsup, an intrinsically disordered, highly positively charged protein. Dsup has been shown to bind to DNA in vitro, a property that has been associated with the capability of Dsup to exhibit stress-protective effects when expressed in mammalian cells. However, DNA binding of Dsup has not been visualized in living cells and expression of Dsup in different cell types was associated with either protective or detrimental effects.

Manipulating arbitrarily shaped Mathieu bottle beams based on geometric factor design.

We demonstrate arbitrarily shaped Mathieu bottle beams (MBBs) based on geometric factor design. By elaborately selecting elliptical trajectory parameters and corresponding orders, the MBBs can be tailored to diverse longitudinal and transversal shapes simultaneously. The proposed method breaks through the limitation that the components of conventional bottle beams can only self-accelerate along paraxial paths with fixed shapes.

Sustainable leather alternatives: High-performance and dyeable bio-based materials from fungal chitin and tannic acid.

Leather alternatives (LAs) offer a promising solution to address the environmental and ethical concerns associated with traditional leather production relying animal hides and chemical tanning agents. However, synthetic polymer-based LAs, such as polyurethane and polyvinyl chloride, have limited broader applications due to their complex manufacture process, high emission of volatile organic compounds, and poor biodegradability. Herein, we present the development of biomass-based LAs fabricated by combining two low-cost natural components - fungal chitin and plant polyphenols (i.
