The rapid reaction between lead iodide (PbI2) and formamidinium iodide (FAI) complicates the fabrication of high-quality formamidinium lead iodide (FAPbI3) films. Conventional methods, such as using nonvolatile small molecular additives to slow the reaction, often result in buried interfacial voids and molecule diffusion, compromising the devices' operational stability. In this study, we introduced a molecular "thruster"-a hypervalent iodine (III) compound with three carbonyl groups and a C--I⁺ bond-that possesses coordination and dissociation abilities, enabling programed modulation of perovskite-film growth kinetics.

Article Synopsis
  • - The study examined radiation exposure in 30 patients with gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) treated with [Lu]Lu-DOTA-TATE in China, focusing on radiation safety for patients and healthcare workers.
  • - Researchers measured external dose rates and radiation doses to nurses and surroundings during and after treatment, determining safe contact times for patients' family members and coworkers post-therapy.
  • - The findings established guidelines for when patients can resume daily interactions with others and confirmed that radiation exposure to medical staff and the hospital environment remained below national safety limits.

Background: Testosterone deficiency is linked to an increased prevalence of non-alcoholic fatty liver disease (NAFLD), although the mechanisms underlying this association are not fully understood. Ferroptosis, a regulated cell death pathway driven by iron-dependent lipid peroxidation, has been suggested to play a role in NAFLD pathogenesis. Since testosterone deficiency is associated with lipid disorders and iron deposition, we hepothesize that ferroptosis may be involved in the pathogenesis of diet-induced NAFLD exacerbated by testosterone deficiency.

  • Mitochondrial DNA copy number (mtDNA-CN) was studied to determine its potential link to 20 different autoimmune diseases (ADs) using Mendelian randomization and meta-analysis methods.
  • The analysis found that, overall, mtDNA-CN did not significantly correlate with risk for ADs, but showed a positive causal association with autoimmune hypothyroidism and rheumatoid arthritis specifically.
  • Other autoimmune conditions examined, like psoriasis and lupus, did not demonstrate any causal relationship with mtDNA-CN, suggesting that the link is not universal across all ADs.

  • The study investigated the effectiveness of gallium 68 (Ga)-labeled fibroblast activation protein inhibitor (FAPI) PET/CT in diagnosing gastric mucinous adenocarcinoma (MAC) and signet ring cell carcinoma (SRCC), comparing it to the standard fluorine 18 (F) fluorodeoxyglucose (FDG) PET/CT.
  • Results showed that Ga-FAPI PET/CT had significantly higher accuracy in detecting lymph node involvement and peritoneal metastases, leading to treatment strategy changes for about 30% of participants.
  • The study concluded that Ga-FAPI PET/CT not only provided better diagnostic accuracy but also served as a strong predictor for progression-free survival in patients with these types of

  • Many cancer patients do not respond effectively to immune checkpoint inhibitors, making it crucial to predict and monitor these responses.
  • A new PET/CT imaging probe, [Ga]Ga-NOTA-GSI, was tested on 72 gastric cancer patients to see if it could assess treatment effects early in immunotherapy.
  • Results showed that responders had significantly higher imaging parameters (like SUV, TLR, TBR) than nonresponders, indicating the probe could potentially help identify which patients benefit from treatment.

Background: The management of non-small cell lung cancer (NSCLC) often includes the use of radiotherapy, with individual outcomes being impacted by the tumor's response to this treatment modality. Cephalomannine (CPM), a taxane diterpenoid found in Taxus spp, has been found to have anti-tumor activity. This study was aim to the explore the role and mechanism by which CPM affects radiotherapy resistance in NSCLC.

Rosiglitazone (RSG), as an insulin-sensitizing drug to treat type 2 diabetes mellitus (T2DM) is reported to decrease bone quality and increase bone fracture risk. The multiple off-target effects of Resveratrol (RSV), a natural specific agonist of Sirtuin1 (Sirt1) with pro-osteoblastogenesis and anti-adipogenesis effects, on bone loss in T2DM are still under discussion. In this study, successfully ovariectomized rats were fed with high-fat diet and STZ (HFD/STZ) to induced T2DM mice.

Actin filament assembly and the regulation of its mechanical properties are fundamental processes essential for eukaryotic cell function. Residue E167 in vertebrate actins forms an inter-subunit salt bridge with residue K61 of the adjacent subunit. Saccharomyces cerevisiae actin filaments are more flexible than vertebrate filaments and have an alanine at this position (A167).

Common challenges in cryogenic electron microscopy, such as orientation bias, conformational diversity, and 3D misclassification, complicate single particle analysis and lead to significant resource expenditure. We previously introduced an in silico method using the maximum Feret diameter distribution, the Feret signature, to characterize sample heterogeneity of disc-shaped samples. Here, we expanded the Feret signature methodology to identify preferred orientations of samples containing arbitrary shapes with only about 1000 particles required.

Deoxynivalenol (DON), a mycotoxin produced by Fusarium, poses a significant risk to human health and the environment. Therefore, the development of a highly sensitive and accurate detection method is essential to monitor the pollution situation. In response to this imperative, we have devised an advanced split-type photoelectrochemical (PEC) sensor for DON analysis, which leverages self-shedding MOF-nanocarriers to modulate the photoelectric response ability of PEC substrate.

Introduction: Aims of the study were to assess the differences in the diagnostic efficacy of 68Ga-somatostatin receptor analogs (68Ga-SSAs) and 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) for detecting bone metastases in neuroendocrine neoplasm (NEN) and to analyze the correlation between imaging features and clinical features of BMs.

Methods: We retrospectively analyzed the clinical and imaging data of 213 NEN patients who underwent 68Ga-SSA PET/CT and were finally diagnosed as BMs by pathology or follow-up. Of those, 103 patients underwent 18F-FDG PET/CT within 7 days after 68Ga-SSA PET/CT.
