Background: Hepcidin is an antimicrobial peptide involved in innate immunity, and the addition of hepcidin or probiotics expressing hepcidin to feed can significantly enhance the disease resistance of farmed animals. Lactobacillus plantarum has the advantages of stable colonization in the animal gut, promotion of intestinal health, and efficient expression of foreign proteins. Previously, we have used L.

Objective: To measure the dangerous depth and the effective safe depth of needling at acupoints of kidney regions based on MRI imaging, and to provide the imaging support for clinical practice.

Methods: The abdominal enhanced T1 MRI imaging of horizontal plane of 61 healthy subjects was included, the anatomical structure of bilateral Weishu (BL 21), Sanjiaoshu (BL 22), Shenshu (BL 23), Weicang (BL 50), Huangmen (BL 51) and Zhishi (BL 52) was analyzed, and the dangerous depth and effective safe depth of perpendicular and oblique needling were measured between the left and right sides and subjects with different body sizes.

Results: There were no significant differences between dangerous depth and effective safe depth of perpendicular and oblique needling at bilateral acupoints of kidney region (>0.

Background: Single-shot diffusion-weighted imaging (ssDWI) has been shown useful for detecting active bowel inflammation in Crohn's disease (CD) without MRI contrast. However, ssDWI suffers from geometric distortion and low spatial resolution.

Purpose: To compare conventional ssDWI with higher-resolution ssDWI (HR-ssDWI) and multi-shot DWI based on multiplexed sensitivity encoding (MUSE-DWI) for evaluating bowel inflammation in CD, using contrast-enhanced MR imaging (CE-MRI) as the reference standard.

Background: Functional electrical stimulation is an important therapy technique for dropfoot correction. In order to achieve natural control, the parameter setting of FES should be associated with the activation of the tibialis anterior.

Methods: This study recruited nine healthy subjects and investigated the relations of walking speed with the onset timing and duration of tibialis anterior activation.

Functional electrical stimulation (FES) is important in gait rehabilitation for patients with dropfoot. Since there are time-varying velocities during FES-assisted walking, it is difficult to achieve a good movement performance during walking. To account for the time-varying walking velocities, seven poststroke subjects were recruited and fuzzy logic control and a linear model were applied in FES-assisted walking to enable intensity- and duration-adaptive stimulation (IDAS) for poststroke subjects with dropfoot.

Two thermoresponsive polymers based on alkyl modified poly-vinylpyrrolidone (PVP) that exhibit very sensitive and reversible temperature-dependant water solubility are described. The application of these polymers as Au nanocatalyst stabilizers leads to a "smart" thermoresponsive Au nanoparticle catalyst.

Conclusions: Our study suggests that aquaporins 4 and 5 (AQP4 and AQP5) in the middle ear cavity may play a vital role in the homeostasis of the tubotympanum and in the course of the accumulation of the effusion in secretory otitis media (SOM).

Objective: To explore the pathological change in water homeostasis in the middle ear in SOM and to observe the expression and regulation of AQP4 and AQP5 in the middle ear cavity in SOM.

Materials And Methods: Reverse transcriptase polymerase chain reaction (RT-PCR) and Western blotting were used to detect AQP4 and AQP5 in the bullae of animal models of SOM and normal animals.
