Design and Analysis of a Rotational Leg-type Miniature Robot with an Actuated Middle Joint and a Tail （RoMiRAMT-II）

引用

Journal of Bionic Engineering 2018年第2期15卷 356-367页

作者： Bokeon Kwak Joonbum bae Department of Mechanical Engineering UNIST Ulsan 44919 Korea

In this paper, a rotational leg-type miniature robot with a bioinspired actuated middle joint and a tail is proposed for stable locomotion and improved climbing ability. The robot has four independently actuated rotational legs, giving it advantages of both wheel-type and leg-type locomotion. The design parameters of the rotational legs were determined by 3D simulation within the seven candidates that selected by a newly proposed metric. It also has unique characteristics inspired by biological structures： a middle joint and a tail. An actuated middle joint allows the frontal body to be lifted or lowered, which was inspired by a flexible body joint of animals, to climb higher obstacles. Effectiveness of the middle joint was analytically verified by the geometric analysis of the robot. Additionally, a multi-functional one Degree Of Freedom （1-DOF） tail was added; the tail prevented the body being easily flipped, while allowed the robot to climb higher obstacles. A bristle-inspired micro structure was attached to the tail to enhance straightness of locomotion. Body size of the robot was 158 mm × 80 mm × 85 mm and weighed 581 g including a 7.4 V Li-Polymer battery. The average velocity of the robot was 2.74 m·s ^-1 （17.67 body lengths per second） and the maximum height of an obstacle that the robot could climb was 106 mm （2.5 times of leg length）, which all were verified by experiments.

Objective: To investigate the potential alleviating effects of acupuncture on maternal separation(MS)-induced changes in plasma pro-inflammatory cytokine levels of rat pups. Methods: On postnatal day 15, rat pups were randomly assigned to 4 groups(n=6 per group) using a random number table: normal, MS, MS with acupuncture stimulation at Shenmen(HT 7) acupoint(MS+HT 7), and MS with acupuncture stimulation at Chengshan(BL 57) acupoint(MS+BL 57) groups. Rat pups in the normal group were housed with their mothers under standard conditions; those in the MS, MS+HT 7 and MS+BL 57 groups were maternally separated and individually maintained. Acupuncture stimulation was performed at HT 7 or BL 57 acupoints once a day for 7 consecutive days. A tail suspension test was performed to measure immobility time of rats and the plasma was collected on postnatal day 21, then levels of corticosterone(CORT), interleukin(IL)-1β, IL-6 and glial cell-derived neurotrophic factor(GDNF) in plasma were measured. Results: Compared with the normal group, the immobility time and the plasma levels of CORT, IL-1β, IL-6 and GDNF in the MS group were significantly increased(P<0.05 or P<0.01). Compared with the MS group, the immobility time and the plasma levels of CORT, IL-1β, IL-6 and GDNF were significantly reduced in the MS+HT 7 group(P<0.05 or P<0.01). Moreover, the immobility time and plasma levels of IL-1β and IL-6 in the MS+HT 7 group were significantly lower than those in the MS+BL 57 group(P<0.05). Conclusion: Acupuncture stimulation at HT 7 can alleviate the behavioral impairment and changes of the cytokines by MS, indicating that acupuncture can help to relieve MS-induced depression.

Clinical significance of tumor-infiltrating lymphocytes for gastric cancer in the era of immunology

World Journal of Gastrointestinal Oncology 2017年第7期9卷 293-299页

作者： Byung Woog Kang Jong Gwang Kim In Hee lee Han Ik bae An Na Seo Department of Hematology/Oncology Kyungpook National University Hospital Kyungpook National University School of Medicine Department of Pathology Kyungpook National University Hospital Kyungpook National University School of Medicine

Immunotherapy has begun to revolutionize cancer treatment, by introducing therapies that target the host immune system instead of the tumor, therapies that possess unique adverse event profiles, and therapies that may cure certain types of cancer. The immune microenvironment of tumors is emerging as the most important means of understanding the relationship between a patient' immune system and their cancer, informing prognosis, and guiding immunotherapy, such as an antibody blockade of immune checkpoints. For some solid tumors, simple quantitation of lymphocyte infiltration would seem to have prognostic significance, suggesting that lymphocyte infiltration is not passive but may actively promote or inhibit tumor growth. For gastric cancers, several studies have provided strong evidence that immune cells contribute to determining prognosis. However, the exact role of immune cells in gastric cancer remains unclear. Therefore, this review focuses on the clinical significance of immune cells, especially tumor-infiltrating lymphocytes, in gastric cancer.

On Uniform Decay for Transmission Problem of Kirchhoff Type Viscoelastic Wave Equation

引用

Acta Mathematica Sinica,English Series 2010年第7期26卷 1197-1206页

作者： Jeong Ja bae Department of Mathematics Dongeui University

In this paper we consider the large time behavior of solutions to an n-dimensional transmission problem for two Kirchhoff type viscoelastic wave equations, that is, the wave propagation over bodies consisting of two physically different types of materials. One component is a simple elastic part while the other is a viscoelastic component endowed with a long range memory. We show that the dissipation produced by the viscoelastic part is strong enough to produce exponential or polynomial decay of the solution

Type 2 innate lymphoid cells (ILC2s) have emerged as key regulators of the immune response in renal inflammatory diseases such as lupus nephritis. However, the mechanisms underlying ILC2 adhesion and migration in the kidney remain poorly understood. Here, we revealed the critical role of integrin α4β7 in mediating renal ILC2 adhesion and function. We found that integrin α4β7 enables the retention of ILC2s in the kidney by binding to VCAM-1, E-cadherin, or fibronectin on structural cells. Moreover, integrin α4β7 knockdown reduced the production of the reparative cytokine amphiregulin (Areg) by ILC2s. In lupus nephritis, TLR7/9 signaling within the kidney microenvironment downregulates integrin α4β7 expression, leading to decreased Areg production and promoting the egress of ILC2s. Notably, IL-33 treatment upregulated integrin α4β7 and Areg expression in ILC2s, thereby enhancing survival and reducing inflammation in lupus nephritis. Together, these findings highlight the potential of targeting ILC2 adhesion as a therapeutic strategy for autoimmune kidney diseases.
