GPR120 is a free fatty acid receptor capable of signalling excess fatty acids. GPR120 can be activated by various types of free fatty acids, causing intracellular signal transduction and exerting energy regulation, immune homeostasis, and neuronal functions. It has been suggested that Trp198 may be an important residue in the recognition and activation of GPR120 by fatty acid ligands, but direct experimental evidence is lacking.

Candida auris is an emerging fungal pathogen that poses a significant threat to global health due to its multidrug resistance and ability to persist in healthcare settings. A key factor contributing to its survival and virulence is its capacity to combat oxidative stress, a process primarily driven by oxidative stress-related enzymes. One such enzyme, d-arabinose dehydrogenase from C.

Dermatosis neglecta (DN) is a rare condition, often linked to psychosomatic disorders, with an unclear etiology. Chilblain lupus erythematosus (CHLE) constitutes a rare variant of cutaneous lupus erythematosus, frequently mistaken for idiopathic chilblain due to its chilblain-like lesions. To date, no instances of concurrent DN and CHLE occurring at the site of a skin flap or graft have been documented.

Given concerns about treatment, there is uncertainty surrounding the effect of prior malignancy on the survival of individuals with metastatic colorectal cancer. This study sought to evaluate how prior malignancy impacts the survival of patients with metastatic colorectal cancer (mCRC). Patients diagnosed with stage IV mCRC (per the American Joint Committee on Cancer [AJCC] 6th edition) between 2004 and 2015 were identified from the Surveillance, Epidemiology, and End Results (SEER) database.

Linker structures are a crucial component of proteolysis-targeting chimeras (PROTACs) and have traditionally been designed based on empirical methods, which presents significant challenges in the development of PROTACs. Current optimization strategies typically focus on reducing the number of rotatable bonds in the linker to limit conformational freedom. However, this approach overlooks the complexity of the target protein degradation process.

Formaldehyde (HCHO) is a harmful volatile organic pollutant, which is commonly found in interior decoration and furniture products. Therefore, it is necessary to develop a gas sensor that can quickly and accurately detect formaldehyde for human health and environmental protection. In order to achieve this goal, in this work, SnS/SnO heterostructure was synthesized by in-situ sulfurization process on the basis of SnO nanospheres, and its formaldehyde sensing performance was studied.

Wood based composites with low density and great flame retardancy are increasingly required as sustainable and low-carbon building materials for energy conservation. In this work, the symbiosis between bio-based calcium alginate (CaA) and delignified wood was fabricated to form delignified wood-CaA aerogel composites. The density of the delignified wood@CaA sample was dropped to only 89 kg/m from 120 kg/m of the control wood.

Solar-driven photocatalytic green hydrogen (H) evolution reaction presents a promising route toward solar-to-chemical fuel conversion. However, its efficiency has been hindered by the desynchronization of fast photogenerated charge carriers and slow surface reaction kinetics. This work introduces a paradigm shift in photocatalyst design by focusing on the synchronization of charge transport and surface reactions through the use of twin structures as a unique platform.

Injectable calcium phosphate cement (CPC) offers significant benefits for the minimally invasive repair of irregular bone defects. However, the main limitations of CPC, including its deficiency in osteogenic properties and insufficient large porosity, require further investigation and resolution. In this study, alginate-chitosan-alginate (ACA) microcapsules were used to encapsulate and deliver rat bone mesenchymal stem cells (rBMSCs) into CPC paste, while a porous CPC scaffold was established to support cell growth.

Metal-organic frameworks (MOFs) have emerged as promising electrode materials for supercapacitors (SCs) due to their highly porous structures, tunable chemical compositions, and diverse morphologies. However, their applications are hindered by low conductivity and poor cycling performance. A novel approach for resolving this issue involves the growth of layered double hydroxides (LDHs) using MOFs as efficient templates or precursors for electrode material preparation.

Multiobject tracking (MOT) is a fundamental problem in computer vision with numerous applications, such as intelligent surveillance and automated driving. Despite the significant progress made in MOT, pedestrian attributes, such as gender, hairstyle, body shape, and clothing features, which contain rich and high-level information, have been less explored. To address this gap, we propose a simple, effective, and generic method to predict pedestrian attributes to support general reidentification (Re-ID) embedding.
