A deep comparative analysis of brain functional connectome across species in primates has the potential to yield valuable insights for both scientific and clinical applications. However, the interspecies commonality and differences are inherently entangled with each other and with other irrelevant factors. Here we develop a novel contrastive machine learning method, called shared-unique variation autoencoder (SU-VAE), to allow disentanglement of the species-shared and species-specific functional connectome variation between macaque and human brains on large-scale resting-state fMRI datasets.

Background: Identifying biomarkers to predict responses for neoadjuvant immunotherapy in resectable non-small cell lung cancer (NSCLC) is under intensive study. Considering the interplay between cancer, inflammation, and immunosuppression, we hypothesized that circulating and imaging inflammatory markers could serve as indicators of anti-tumor immune responses, and thus conducting an exploratory study to reveal the predictive value of combining longitudinal systemic inflammatory markers in stratifying pathologic response to neoadjuvant sintilimab.

Methods: We retrospectively reviewed 36 patients (29 male and seven female) with NSCLC (stage IA-IIIB) who underwent pre- and post-treatment peripheral blood tests and F-fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG PET/CT) scans before and after two cycles of neoadjuvant sintilimab (registration number: ChiCTR-OIC-17013726).

Article Synopsis
  • This study compares the effectiveness of repeat laparoscopic hepatectomy (r-LH) and radiofrequency ablation (RFA) in treating patients with recurrent hepatocellular carcinoma (RHCC) based on clinical outcomes and survival rates.
  • Data from 272 RHCC patients were analyzed, revealing that while RFA resulted in shorter hospital stays and fewer complications, r-LH significantly improved overall and disease-free survival rates.
  • Particularly, patients with solitary tumors or those located near critical structures benefitted more from r-LH, especially when tumors were 5 cm or smaller, suggesting it as a more favorable treatment option in these cases.

At present, animal bone glue has been widely used in industry, but there are no relevant research reports on its application in the petroleum industry. In this paper, the rheological properties, inhibition, filtration, and temperature resistance performance of modified bone glue (Mbg) were evaluated in water-based drilling fluids, and the results showed that Mbg can significantly affect the performance of water-based muds with minimal dosage, and temperature resistance of Mbg could reach up to 130 °C. The inhibition mechanism of Mbg in drilling fluids was investigated by infrared spectroscopy (FT-IR), X-ray diffraction (XRD), zeta potential, thermogravimetric analysis (TGA), and scanning electron microscope (SEM).

Waste drilling fluids produced from oil extraction can cause serious harm to the ecological environment; thus, the treatment of waste drilling fluids is urgent and important to ensure the sustainability and development of the oil extraction. In this work, we used the Fenton-like reaction method to degrade waste drilling fluids with SiO-supported MnO@FeO composite material as a catalyst in the presence of HO. During the Fenton-like reaction process, the MnO@FeO interface exhibits exceptional activity by facilitating the production of ·OH species with high activity and strong oxidizing properties, which degrade the organic substances in the waste drilling fluids into smaller inorganic molecules, thereby reducing its COD value.

Cortical folding is closely linked to brain functions, with gyri acting more like local functional "hubs" to integrate information than sulci do. However, understanding how anatomical constraints relate to complex functions remains fragmented. One possible reason is that the relationship is estimated on brain mosaics divided by brain functions and cortical folding patterns.

Article Synopsis
  • Anti-PD-L1 combination immunotherapy is the first-line treatment for unresectable hepatocellular carcinoma (HCC), but its effectiveness is limited, with less than 40% of patients responding.
  • Research found that nonresponders had higher activation of the renin-angiotensin system and lower ACE2 expression, which is linked to HCC progression and resistance to treatment.
  • Targeting the ACE2 axis may improve responses to anti-PD-L1 therapy by reducing immunosuppressive factors in the tumor environment, positioning it as both a potential therapeutic target and a biomarker for predicting treatment success.

Article Synopsis
  • ZBP1 (Z-DNA binding protein 1) is an immune sensor that activates the NLRP3 inflammasome during viral infections, but this function is inhibited by the herpesvirus pseudorabies virus (PRV) through its VP22 protein.
  • The study reveals that VP22 acts as a virulence factor for PRV, preventing ZBP1 from triggering NLRP3 activation, which would normally help combat the infection.
  • When ZBP1 is deficient, a recombinant PRV lacking VP22 replicates more effectively, indicating that VP22's interference with ZBP1’s function is crucial for PRV's pathogenicity.
