All functional images were acquired using a 3.0 T MR Siemens scanner, with a 12 channels head coil (Siemens Magnetom Trio Tim, Siemens, Erlangen, Germany. During real-time fMRI-based emotion regulation, standard echo planar imaging (EPI) images consisting of sixteen axially oriented slices (voxel size = 3 × 3 × 5 mm³, slice gap = 1 mm) were acquired (repetition time TR = 1500 ms, matrix size = 64 × 64, FoV = 192 × 192 mm, TE = 30 ms). Considering that the primary respiratory-related component of the fMRI signal usually fluctuates at about 0.3 Hz, a TR equal to 1.5 s prevents aliasing of the first respiratory harmonics with a spectral signature of the typical BOLD effect [48 (link)]. Additionally, a gradient echo field map (TR 488 ms, TE 1 = 4.49 ms, TE 2 = 6.95 ms) and a T1-weighted MPRAGE structural scan (matrix size = 256 × 256, 160 partitions, 1 mm³ isotropic voxels, TR = 2300 ms, TE = 3.93 ms, TI = 1100 ms, α = 8°) were acquired from each participant to reduce geometric distortion due to magnetic field inhomogeneities [49 (link)]. In order to minimize head movements, two foam cushions were positioned around the participant’s head.

Participants lay supine on the fMRI scanner bed, and viewed the task back-projected onto a screen through a mirror attached onto the head coil. Foam pads were used to minimize head motion. Stimulus presentation and timing of all stimuli and response events were achieved by using E-prime 2.0 (Psychology Software Tools, Inc. Pittsburgh, PA, USA) on a windows PC. Participants’ responses were collected online using an MRI-compatible button box. The fMRI images were acquired with a Siemens 3T scanner (Siemens Magnetom Trio TIM, Erlangen, Germany) at the Brain Imaging Center of Southwest University. Each functional run involved the acquisition of 197 EPI volumes (slices = 32, TR/TE = 2000 ms/30 ms, flip angle = 90°, FOV = 220 × 220 mm², matrix size = 64 × 64, slice thickness = 3 mm, and slice gap = 1 mm). After the participants completed 8 functional runs, three-dimensional high-resolution T1 anatomical images were recorded with a total of 176 slices at a thickness of 1 mm and in-plane resolution of 0.98 × 0.98 mm (TR/TE = 1900 ms/2.52 ms, flip angle = 90°, and FOV = 256 × 256 mm²).

Images were acquired using a 3.0-Tesla scanner (Siemens Magnetom Trio Tim, Siemens Medical Solutions, Erlangen, Germany) utilizing 32 channel head coil in Tianjin First Central Hospital, Tianjin, China. Before scanning, the patient was asked to lay in a supine position in the MRI table with head firmly fixed by straps and foam pads to minimize head movement.
For resting-state (RS) scanning, participants were asked to close the eyes and remain motionless and not to think of anything, in particular nor fall asleep. The RS functional data were acquired using an echo-planar imaging sequence with the following parameters: TR = 2000 ms, TE = 30 ms, flip angle = 90°, thickness/gap = 5.0/0.0 mm, field of view = 24 cm × 24 cm, matrix = 64 × 64, 300 volumes. A total of 300 slices of resting fMRI were acquired.
Structural images T1-weighted images were acquired using a magnetization-prepared rapid gradient-echo sequence with the following parameters: TR = 1900 ms, TE = 2.52 ms, TI = 900 ms, thickness = 1.0 mm, flip angle = 9°, matrix = 256 × 256, voxel size = 1 × 1×1 mm³.

Magnetic properties of ENO1‐Dex‐g‐PCL/SPIO nanoparticles were detected by superconducting quantum interference magnetometer (Quantum Design Inc) at room temperature after lyophilization. Next, the efficiency of T2 relaxation for nanoparticles was examined by 1.5T MRI (Siemens Magnetom Trio Tim, Siemens AG) as previously reported.¹⁶We prepared SPIO and ENO1‐SPIO granule solutions with iron concentrations of 30, 15, 7.5, 3.75, 1.875 and 0.9375 ug/mL and then added 1 mL 2% agarose to prepare a final concentration of 1% agarose. Next, 1% agarose was used as a blank control to detect the T2 value and T2* value of different concentrations of iron particle solution. The corresponding relaxation rates R2 and R2* were calculated as 1/T2 and 1/T2*, respectively.

In order to minimize head movements two foam cushions were positioned around participant's head.

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
