Fatty acid binding protein 4 (FABP4) is highly expressed in adipocytes. Lipolysis, caused by an elevated adrenergic input, has been suggested to contribute to elevated serum FABP4 levels in patients with cardiovascular diseases. However, the relationship between the serum FABP4 and efferent sympathetic nerve activity remains poorly understood.

To improve imputation quality for genome-wide association studies (GWAS) conducted on the Japanese population, we developed and evaluated four Japanese population-specific reference panels. These panels were constructed through the augmentation of the 1000 Genomes Project (1KG) panel using Japanese whole genome sequencing (WGS) data, with sample sizes ranging from 1 K to 7 K individuals enrolled through the Biobank Japan (BBJ) project, and sequencing depths ranging from 3× to 30×. Among these panels, an augmented reference panel comprising 7472 WGS samples of mixed depth (1KG+7K) exhibit the greatest improvement in imputation quality relative to the Trans-Omics for Precision Medicine (TOPMed) reference panel.

In water, the nonionic surfactant pentaethylene glycol monododecyl ether (C12E5) forms multi-lamellar vesicles upon application of shear, attributed to buckling instability of the surfactant layers. In the standard setup for applying shear, a pair of solid substrates is moved in opposite directions, and a non-slip condition at the solid surface is assumed. Based on theoretical predictions, the effective viscosity of the fluid surrounding the membrane is modified in this process, and this confinement may affect membrane fluctuation.

Article Synopsis
  • Osimertinib is effective as a first-line treatment for patients with EGFR mutation-positive NSCLC, with a median progression-free survival of 20 months and overall survival of 41 months in a multicenter study of 583 patients.
  • Adverse events occurred in 23.3% of patients, and different progression patterns were identified, with many patients remaining asymptomatic upon progression.
  • Continuing osimertinib post-progression may not be beneficial, as those who discontinued treated had better survival rates compared to those who persisted on the drug, suggesting a need for a shift to alternative therapies like platinum plus pemetrexed for improved outcomes.

  • SCLC has traditionally been viewed as a single entity, hindering advances in treatment; however, identifying genetic differences is key to improving patient outcomes.
  • A study analyzed over 1000 SCLC samples using genomic screening to identify five distinct genetic subgroups, which can respond differently to therapies, especially targeted treatments.
  • The findings indicate that while certain subgroups, like the NSCLC and MYC subgroups, have poorer survival rates with standard treatments, others may benefit from specialized therapies, highlighting the importance of personalized medicine in SCLC management.

Emerging evidence suggests that the localization of viral movement proteins (MPs) to both plasmodesmata (PD) and viral replication complexes (VRCs) is the key to viral cell-to-cell movement. However, the molecular mechanism that establishes the subcellular localization of MPs is not fully understood. Here, we investigated the PD localization pathway of red clover necrotic mosaic virus (RCNMV) MP and the functional regions of MP that are crucial for MP localization to PD and VRCs.

Neuroendocrine neoplasms (NENs) encompass tumors arising from neuroendocrine cells in various organs, including the gastrointestinal tract, pancreas, adrenal gland, and paraganglia. Despite advancements, accurately predicting the aggressiveness of gastroenteropancreatic (GEP) NENs based solely on pathological data remains challenging, thereby limiting optimal clinical management. Our previous research unveiled a crucial link between hypermethylation of the protocadherin PCDHGC3 gene and neuroendocrine tumors originating from the paraganglia and adrenal medulla.

We developed pulmonary emphysema and a type 2 airway inflammation overlap mouse model. The bronchoalveolar lavage (BAL) interleukin 13 (IL-13), IL-4, and IL-5 levels in the overlap model were higher than in the pulmonary emphysema model and lower than in the type 2 airway inflammation model, but IL-33 level in the lung was higher than in other models. IL-33 and interferon-γ (IFNγ) in lungs may control the severity of a type 2 airway inflammation in lung.

The chemical reaction between Fe and lacquer has been used to create the black color in lacquer coatings since ancient times. Here, the effects of Fe ion addition, UV irradiation, and heating on the microscopic structures of black lacquer films were investigated by using X-ray absorption near edge structure (XANES), extended X-ray absorption fine structure (EXAFS), Fourier transform-infrared spectroscopy (FT-IR), small-angle X-ray scattering (SAXS), and small angle neutron scattering (SANS). The EXAFS result indicated that heating and UV irradiation made the coordination structure of Fe in the lacquer nonuniform, and that heating caused the greatest nonuniformity.
