The aim of this study was to evaluate the role of NLRP3 inflammasome on BU/CY-induced liver inflammation in mice after HSCT. HSCT mice model was established through infusion of 5 × 10(6) bone marrow mononuclear cells after conditioned with BU/CY. On day 7, 14, 21 and 28 after HSCT, mice were sacrificed for analysis of liver inflammation, cytokine secretion,(More)
Donor-derived CD4(+) T lymphocytes are the major effector cells directly involved in the development of graft-versus-host disease (GVHD). As a negative regulator of immune cell differentiation and development, microRNA-150 (miR-150) induces immunological tolerance in CD4(+) T cells after transplantation. However, the specific mechanisms have not been fully(More)
Measurement of force on a micro- or nano-Newton scale is important when exploring the mechanical properties of materials in the biophysics and nanomechanical fields. The atomic force microscope (AFM) is widely used in microforce measurement. The cantilever probe works as an AFM force sensor, and the spring constant of the cantilever is of great significance(More)
The paper proposes a new intelligent control method to precisely control the tip motion of the atomic force microscopy (AFM). The tip moves up and down at a high rate along the z direction during scanning, requiring the utilization of a rapid feedback controller. The standard proportional-integral (PI) feedback controller is commonly used in commercial AFMs(More)
A simple rate adaptive control method is proposed to improve the imaging speed of the atomic force microscope (AFM) in the paper. Conventionally, the probe implemented on the AFM scans the sample surface at a constant rate, resulting in low time efficiency. Numerous attempts have been made to realize high-speed AFMs, while little efforts are put into(More)
Acute lymphoblastic leukemia (ALL) is the most common hematological malignancy diagnosed in children and is a malignant disorder that originates from one single hematopoietic precursor committed to B- or T-cell lineage. C-C chemokine receptor type 5 (CCR5) is a chemokine and chemokine receptor pair playing critical roles in tumorigenesis. A highly potent(More)
A new electromechanical coupling model was built to quantitatively analyze the tuning fork probes, especially the complex ones. A special feature of a novel, soft tuning fork probe, that the second eigenfrequency of the probe was insensitive to the effective force gradient, was found and used in a homemade bimodal atomic force microscopy to measure power(More)
The atomic force microscope (AFM) is a powerful instrument which can measure the surface of samples at the nanoscale. The resonance of the scanner in xy directions, and the feedback control in the z direction are two major sources of image distortion at high scan speed. In order to improve the scanning speed of the AFM, a low-cost and easy method, which(More)
Chronic lymphocytic leukemia (CLL) is the most common leukemia in Western countries, and mainly originates from an accumulation of abnormal B cells caused by the dysregulation of cell proliferation and apoptosis rates. The aberration of apoptosis-related genes in CLL cells results in defective apoptosis of CLL cells in response to traditional therapeutic(More)
For water treatment applications, fabricating a high permeation flux membrane with super-strong mechanical strength and excellent long-term antifouling properties remains a great challenge. In this study, robust, antifouling carbon nanotube (CNT) nanohybrid membranes have been fabricated for oil/water separation. Polyethyleneimine (PEI) with abundant amino(More)
