Aim: To synthesize and identify the hapten and complete antigens for Zearalenone for the purpose of preparation of anti-Zearalenone antibodies.
Methods: Zearalenone and carboxymethoxylamine hemihydrochloride were incubated to synthesize the hapten ZEN-oxime. The ZEN-oxime was identified by thin layer chromatography (TLC), high performance liquid chromatographic (HPLC) and liquid chromatography-tandem mass spectrometry (LC-MSn). The ZEN-oxime was further conjugated to bovine serum albumin (BSA) or ovalbumin (OVA) to form the complete antigens by NHS ester method. The complete antigens were identified by ultraviolet spectrum, 2, 4, 6-trinitrobenzene sulfonicacid method (TNBS) and immunological analysis.
Results: The results indicated that the hapten and complete antigens were prepared successfully.
Conclusion: The hapten and complete antigens for Zearalenone have been successfully synthesized and identified by several methods, which enables further preparation of anti-Zearalenone antibodies.

Background: Recent studies have highlighted the distinct ratio of PD-1 + Treg/PD-1 + CD8 for prognosis prediction. However, it remains unclear about the association of this ratio and tertiary lymphoid structures (TLS) with prognosis and response to neoadjuvant or conversion therapy in advanced gastric cancer.
Methods: Firstly, fresh postoperative samples from 68 gastric cancer patients in Renji Hospital were collected.

Mycobacterium tuberculosis Complex (MTBC), the etiological agent of tuberculosis (TB), demonstrates considerable genotypic diversity with distinct geographic distributions and variable virulence profiles. The pe-ppe gene family is especially noteworthy for its extensive variability and roles in host immune response modulation and virulence enhancement. We sequenced an Mtb genotype L2.

Background Aims: With novel therapies improving prognosis, the complications of multiple myeloma after multi-line treatment, particularly myelosuppression, have become a crucial determinant of long-term outcomes. Non-myeloablative allogeneic hematopoietic stem cell transplantation is a feasible option, but the transplant-related mortality rate remains high. Our study presents a relapsed/refractory multiple myeloma patient with a 9-year disease history.

The elimination of lymphatic filariasis (LF) as a public health problem remains an ongoing challenge in the Pacific region. This study reports on antigen (Ag) and microfilaria (Mf) prevalence in Samoa in 2019, 7-9 months after the completion of the first round of triple-drug mass drug administration (MDA). It evaluates the effectiveness of the intervention for reducing Ag prevalence to below a 2% threshold, and how this differs between 5-9-year-olds and ≥10-year-olds.

Porcine circovirus type 2 (PCV2) is an important swine pathogen that has caused considerable economic losses in the global swine industry. During our surveillance of pigs in Shandong, China, from 2018 to 2020, we found that the PCV2 infection rate was 7.89% (86/1090).
