Background: Fluorine 18-labeled fibroblast activation protein inhibitor (F-FAPI-04) positron emission tomography/computed tomography (PET/CT) has shown promise for the visualization of advanced stage lung cancer. The accuracy of F-FAPI-04 compared with that of fluorine-18 labeled-fluorodeoxyglucose (F-FDG) in detecting early lung adenocarcinoma (LUAD) remains unknown. Taking the surgical pathology of pulmonary nodule as the gold standard, the diagnostic performance of stage IA LUAD were compared between F-FAPI-04 PET/CT and F-FDG PET/CT, and the correlation between F-FAPI-04 uptake and pathological characteristics of stage IA LUAD.

Efficient profiling of circulating extracellular vesicles (EVs) benefits noninvasive cancer diagnosis and therapeutic monitoring, but is technically hampered by tedious isolation, multistep washing, and poor sensitivity. Here, we report multifunctional bubbles that enable self-separation, wash-free, single-step, and ultrasensitive profiling of EV surface markers in plasma samples for early diagnosis and treatment monitoring of lung cancer. In this assay, the buoyancy-dominated bubble is electric field-resistant, allowing EV-responsive release of electroactive probes for electrohydrodynamic nanoshearing force-enhanced hybridization, self-separation from the electrode interface for minimizing noise in electrochemical measurements, and one-step wash-free EV profiling.

Background: Obstructive sleep apnea (OSA) is linked to brain alterations, but the specific regions affected and the causal associations between these changes remain unclear.

Methods: We studied 20 pairs of age-, sex-, BMI-, and education- matched OSA patients and healthy controls using multimodal magnetic resonance imaging (MRI) from August 2019 to February 2020. Additionally, large-scale Mendelian randomization analyses were performed using genome-wide association study (GWAS) data on OSA and 3935 brain imaging-derived phenotypes (IDPs), assessed in up to 33,224 individuals between December 2023 and March 2024, to explore potential genetic causality between OSA and alterations in whole brain structure and function.

Chemotherapy is the primary treatment option for pancreatic cancer, although nanocarrier-based drug delivery systems often struggle with multiple physiological barriers, limiting their therapeutic efficacy. Here, we developed a pH/reactive oxygen species (ROS) dual-sensitive self-adaptive nanocarrier (DAT) encapsulating camptothecin (CPT), an analog of the pancreatic chemotherapeutic drug irinotecan (CPT-11), to enhance chemotherapy outcomes in orthotopic pancreatic cancer by addressing multiple physiological barriers. The nanocarrier features a peripherally positively charged arginine (Arg) residue on DAT and is masked with an acid-labile 2,3-dimethylmaleic anhydride (DA) to improve circulation time.

The high-level risk perception diffusion caused by public health emergencies seriously threatens public mental health and social stability. Much scholarly attention focused on the traditional epidemic models or simply combined content and social attributes, overlooking the differences in public individual characteristics. This paper proposes an SSEIIIR model of risk perception diffusion by innovatively subdividing susceptible people and infectious people.

  • Potato black scurf and tobacco target spot are caused by AG-3, which consists of three subgroups (PT, TM, and TB) that correspond to their host plants: potato, tomato, and tobacco.
  • A study analyzed 129 tobacco and 80 potato AG-3 isolates from various regions in China, finding that potato isolates belonged to the PT subgroup, while tobacco isolates were classified into TM and TB subgroups.
  • The research highlighted genetic variations among these subgroups, differences in their biological characteristics and pathogenicity, and noted that AG-3 PT showed the most somatic incompatibility, with distinct differences observed in colony color and morphology.

  • The study investigates the effectiveness of Natural Orifice Specimen Extraction Surgery (NOSES) compared to traditional laparoscopic surgery for treating rectal cancer, as the condition is becoming more prevalent in younger patients.
  • A retrospective analysis of 150 rectal cancer patients was conducted, where those undergoing NOSES were matched with a control group receiving standard laparoscopic surgery to evaluate various surgical and recovery indicators.
  • Results showed that the NOSES group had better outcomes, including quicker recovery times and less pain, indicating that NOSES could be a more effective and less invasive option for rectal cancer treatment.

Background: Risk perception plays a crucial role in workers' unsafe behaviors. However, little research has explored why workers generate biased risk perceptions, namely underestimating or overestimating the risks of unsafe actions. Cognitive biases in risk perception arise from uncertainties about the dangers of unsafe behaviors.

Background: Widely used computed tomography (CT) screening increases the detection of pulmonary pure ground-glass nodules (pGGNs), often classified as the second category of Lung Imaging Reporting and Data System (Lung-RADS 2). Despite their low malignancy risk, these nodules pose significant challenges and necessitate accurate assessment to minimize the risk of long-term follow-ups. This study investigated the detection efficacy of zero echo time (ZTE) magnetic resonance imaging (MRI) and thin-slice fat-saturated T2-weighted imaging (T2WI-FS) on 3.

Enzyme-mediating biotransformations commonly occur in micro- and nanospace, which is crucial to maintain the essential biochemical processes and physiological functions in living systems. Probing enzyme-catalytic reactions in a biomimetic fashion remains challenging due to the lack of competent tools and methodology. Here, we show that studying enzymatic reaction kinetics can be readily achieved by a well-designed solid-state nanopore.

Background: Assembling framework nucleic acid (FNA) nanoarchitectures and tuning luminescent quantum dots (QDs) for fluorescence assays represent a versatile strategy in analytical territory. Rationally, FNA constructs could offer a preferential orientation to efficiently recognize the target and improve detection sensitivity, meanwhile, regulating size-dependent multicolor emissions of QDs in one analytical setting for ratiometric fluorescence assay would greatly simplify operation procedures. Nonetheless, such FNA/QDs-based ratiometric fluorescence nanoprobes remain rarely explored.

Accurately assaying tumor-derived circulating extracellular vesicles (EVs) is fundamental in noninvasive cancer diagnosis and therapeutic monitoring but limited by challenges in efficient EV isolation and profiling. Here, we report a bioinspired buoyancy-driven metal-organic framework (MOF) corona that leverages on-bubble coordination and dual-encoded surface-enhanced Raman scattering (SERS) nanotags to streamline rapid isolation and ultrasensitive profiling of plasma EVs in a single assay for cancer diagnostics. This integrated bubble-MOF-SERS EV assay (IBMsv) allows barnacle-like high-density adhesion of MOFs on a self-floating bubble surface to enable fast isolation (2 min, near 90% capture efficiency) of tumor EVs via enhanced EV-MOF binding.

Osteoporosis is a common chronic bone metabolism disorder characterized by decreased bone mass and reduced bone density in the bone tissue. Osteoporosis can lead to increased fragility of the skeleton, making it prone to brittle fractures. Osteoclasts are macrophage-like cells derived from hematopoietic stem cells, and their excessive activity in bone resorption leads to lower bone formation than absorption during bone remodeling, which is one of the important factors inducing osteoporosis.
