Before starting treatment of chronic glomerulonephritis it is desirable to determine the patient's drug sensitivity in vitro because in the absence of such sensitivity chemotherapy should be preceded by immunomodulation with tactivin or thymalin and 3-5 sessions of plasmapheresis to stimulate drug sensitivity. Further measures include prednisolone or cyclophosphamide intravenously for 3-5 days in a dose 300-500 followed by oral administration. Active treatment lasts for 4-8 weeks. After that the patients receive maintenance for 1-2 years.

Background: Up to 23% of breast cancer patients recurred within a decade after trastuzumab treatment. Conversely, one trial found that patients with low HER2 expression and metastatic breast cancer had a positive response to trastuzumab-deruxtecan (T-Dxd). This indicates that relying solely on HER2 as a single diagnostic marker to predict the efficacy of anti-HER2 drugs is insufficient.

Background: Myelofibrosis (MF) is a clonal haematopoietic disease, with median overall survival for patients with primary MF only 6.5 years. The most frequent gene mutation found in patients is JAK2, causing constitutive activation of the kinase and activation of downstream signalling.

Background: Colorectal cancer (CRC) is a common gastrointestinal cancer, and even though oxaliplatin chemotherapy is effective, there is a high likelihood of relapse, indicating the presence of oxaliplatin-resistant CRC. Therefore, it is crucial to comprehend the molecular mechanisms of oxaliplatin resistance and develop effective strategies to counter drug resistance. Numerous studies have demonstrated the close association between microRNAs (miRNAs) and drug resistance in CRC.

Background: Microsatellite instability-high (MSI-H) metastatic colorectal cancer (CRC) patients are the dominant population in immune checkpoint blockade treatments, while more than half of them could not benefit from single-agent immunotherapy. We tried to identify the biomarker of MSI-H CRC and explore its role and mechanism in anti-PD-1 treatments. Tumor-specific MHC-II was linked to a better response to anti-PD-1 in MSI-H CRC and CD74 promoted assembly and transport of HLA-DR dimers.

Liquid cell transmission electron microscopy (LCTEM) is a powerful technique for investigating crystallisation dynamics with nanometre spatial resolution. However, probing phenomena occurring in liquids while mixing two precursor solutions has proven extremely challenging, requiring sophisticated liquid cell designs. Here, we demonstrate that introducing and withdrawing solvents in sequence makes it possible to maintain optimal imaging conditions while mixing liquids in a commercial liquid cell.
