The co-infection of rice caused by southern rice black-streaked dwarf virus (SRBSDV) and rice ragged stunt virus (RRSV) was widely found at many regions, such as Yunnan Province, China, and North and Central Vietnam. These rice viral diseases lead to seriously yield loss of rice. In this study, the proteomics technology of shotgun and label free combined with multiple reaction monitoring (MRM) was developed to detect rice sample of a single or/and co-infection. The shotgun assay indicated that some proteins coded by SRBSDV and RRSV were detected via the mode of in-gel digestion, except for P5-2, P7-2 and P9-2 of SRBSDV and P4b, P5, P6, P8a and P8b of RRSV. The technology of label free combined with MRM indicated that P2, P5-1, P4, P8, P7-1, P6, P9-1 and P10 of SRBSDV and P1, P3 and P9 of RRSV were higher abundance in rice plant, and P5-2, P7-2 and P9-2 of SRBSDV and P4b and P5 of RRSV were lower abundance in viruliferous-rice plant. So SRBSDV P9-1 and RRSV P3 was selected as marker molecule to be used in detection technology, and the label free combined with MRM technology was established to detect two kinds of rice virus.

Functionalization of polymer nanoparticles (NPs) with targeting peptides is of interest for drug delivery applications to enhance tumor accumulation and penetration. Herein, we evaluated the feasibility of two different methods for the attachment of a tumor-penetrating peptide LinTT1 (AKRGARSTA) to poly(ethylene glycol)-block-poly(ε-caprolactone) (PCL-PEG) NPs: (1) "post-conjugation" onto pre-formed nanoparticles, and (2) "pre-conjugation", the synthesis and purification of peptide-polymer conjugates and subsequent nanoprecipitation of the conjugates diluted with non-functionalized polymers. Conjugation of the labelled peptide via maleimide-thiol chemistry was verified by gel permeation chromatography (GPC) and fluorescence measurements.

Background: Thymic epithelial tumors (TETs), including thymoma and thymic carcinoma, are rare thoracic tumors of the anterior mediastinum. For those with advanced disease, platinum-based chemotherapy is used as first-line treatment. However, there is no standard regimen established for TET at progression after initial therapy, and treatment options for advanced/recurrent TETs are limited.

Propose: This study aimed to evaluate the efficacy and safety of neoadjuvant treatment of darolutamide, a next-generation androgen receptor inhibitor, plus androgen deprivation therapy (ADT) for patients with locally advanced prostate cancer (LAPC).
Methods: This single-arm, multicenter, open-label phase II trial (ClinicalTrials.gov: NCT05249712, 2022-01-01), recruited 30 localized high-risk/very high-risk prostate cancer (HRPCa/VHRPCa) patients from three centers in China between 2021 and 2023.

Introduction: This study aimed to evaluate the safety and preliminary efficacy of serplulimab, a novel programmed death-1 inhibitor, with or without bevacizumab biosimilar HLX04 as first-line treatment in patients with advanced hepatocellular carcinoma.
Methods: This open-label, multicenter phase 2 study (clinicaltrials.gov identifier NCT03973112) was conducted in China and consisted of four treatment groups: group A (serplulimab 3 mg/kg plus HLX04 5 mg/kg, subsequent-line), group B (serplulimab 3 mg/kg plus HLX04 10 mg/kg, subsequent-line), group C (serplulimab 3 mg/kg, subsequent-line) and group D (serplulimab 3 mg/kg plus HLX04 10 mg/kg, first-line).

Background: Host commensal gut microbes are shown to be crucial for microglial maturation, and functions that involve innate immune responses to maintain brain homeostasis. Sex has a crucial role in the incidence of neurological diseases with females showing higher progression of AD compared with males. Transcriptomics has been a powerful tool for the characterization of microglial phenotypes however, there is a large gap in relating to their functional protein abundances.
