The purpose of this study is to suggest that compassion is used as a mechanism to improve immunity by activating people's parasympathetic nerves. Compassion is pity and heartbreak for the misfortune of others. The instinctive emotion of compassion is the basis for humans to achieve and develop society. This is also linked to the laws of nature and the factors of evolution that Kropotkin, famous for his "mutual assistance (mutualism)" that all things help each other. Compassion is an individual's instinctive emotion and at the same time a driving force for forming and developing society. If the Hopeful World (希望世上) performs Korean traditional music healing at a nursing home, first, it will have a positive healing effect on the elderly in the nursing home, who are the audience. Second, positive healing effects can also be expected from performers. The stronger the compassion, the greater the healing effect. Third, people who watch the performance also enjoy the healing effect. This seems to have brought about a synergistic effect by combining the feelings felt while looking at the excellent behavior felt by seeing the poor person. It seems that this effect can be named the compassion effect that developed the Mother Teresa effect. The Mother Teresa effect refers to a significant improvement in the body's immune function just by volunteering or seeing good things. By expanding this Mother Teresa effect, it can be inferred that a pitying heart, helping behavior, and being with good behavior will all help improve the human immune system. This can also be called the compassion effect. Therefore, we think having compassion activates the parasympathetic nerves, improving your mood, and increasing your immunity.

BACKGROUND/OBJECTIVES: The immunomodulatory effect of Platycodon grandiflorum (PG) has been reported, but studies on its mechanism are still lacking. This study was undertaken to confirm whether the hydrolyzed and fermented PG extract (HFPGE) obtained by adding hydrolysis and fermentation to the extraction process has an immune-enhancing effect in the in vivo system. MATERIALS/METHODS: Five-week-old BALB/c mice were divided into 4 groups: normal control group (NOR), control group (CON), 150 mg/kg body weight (BW)/day HFPGE-treated group (T150), and 300 mg/kg BW/day HFPGE-treated group (T300). The mice were administered HFPGE for 4 weeks and intraperitoneally injected with cyclophosphamide (CPA, 80 mg/kg BW/day) on day 6, 7, and 8, respectively, to induce immunosuppression. The levels of immunoglobulins (Igs) and cytokines were measured in the serum. In splenocytes, proliferation and cytokine levels were measured. RESULTS: Serum IgA, IgG, and IgM levels were observed to decrease after CPA treatment, which was recovered by HFPGE administration. The levels of serum interleukin (IL)-12, tumor necrosis factor (TNF)-α, IL-8, and transforming growth factor (TGF)-β were also decreased after exposure to CPA but increased after HFPGE administration. Decreased splenocyte proliferation was seen in CPA-treated mice, but was observed to increase in the T150 and T300 groups as compared to the NOR group. Compared to the CON group, splenocyte proliferation stimulated with concanavalin A (ConA) or lipopolysaccharide (LPS) in the HFPGE-treated groups was significantly increased. The cytokines secreted by ConA-stimulated splenocytes (IL-2, IL-12, interferon-γ, TNF-α) were increased in the T150 and T300 groups, and cytokines secreted by LPS-stimulated splenocytes (IL-4, IL-8, TGF-β) were also increased by HFPGE administration. CONCLUSION: These results suggest that HFPGE stimulates the immunity in immunosuppressed conditions, thereby enhancing the immune response. Therefore, it is expected that HFPGE has the potential to be used as functional food and medicine for immune recovery in various immunocompromised situations.

It has been reported that some exercise could enhance the anti-viral antibody titers after vaccination including influenza and coronavirus disease 2019 vaccines. We developed SAT-008, a novel digital device, consists of physical activities and activities related to the autonomic nervous system. We assessed the feasibility of SAT-008 to boost host immunity after an influenza vaccination by a randomized, open-label, and controlled study on adults administered influenza vaccines in the previous year. Among 32 participants, the SAT-008 showed a significant increase in the anti-influenza antibody titers assessed by hemagglutination-inhibition test against antigen subtype B Yamagata lineage after 4 wk of vaccination and subtype B Victoria lineage after 12 wk (p<0.05). There was no difference in the antibody titers against subtype "A." The SAT-008 also showed significant increase in the plasma cytokine levels of IL-10, IL-1β, and IL-6 at weeks 4 and 12 after the vaccination (p<0.05). A new approach using the digital device may boost host immunity against virus via vaccine adjuvant-like effects.

Although aquaculture shrimp production has increased, disease mortality has also increased. Acute hepatopancreatic necrosis disease (AHPND) is an emerging disease that significantly reduces production. In this study, we have investigated the potential of medicinal herbs in enhancing the immune system of shrimp. A mixture of medicinal herb extracts (Han In-jin, Artemisia iwayomogi kitamura and Cham Dang-gwi, Angelicae gigas Nakai) was absorbed into pellets and fed to whiteleg shrimp Litopenaeus vannamei for 12 weeks. The weight gain, immune activity, and disease resistance effects of the shirmp were examined. The growth performance of shrimp fed the mixture of medicinal herbal extracts was higher than that of the control group. The prophenoloxidase (proPO) activity was found to be significantly higher at 8 weeks in the 0.1% medicinal herb extract fed group. The cumulative mortality when artificially infected with AHPND pathogens commonly decreased in the 8 weeks fed group when compared with the control group. Furthermore, the RPS (relative percentage survival) was improved. This study confirmed that a mixture of medicinal herbal extracts has a positive effect on growth performance, innate immunity and disease resistance in shrimp. The optimum concentration of the medicinal herb extract for shrimp feed was 0.1% .

The PID controller has been widely applied to the most control systems because of its simple structure and east designing. One of the important points to design the PID control system is to tune the approximate control parameters for the given target system. To find the PID parameters using Ziegler Nichols(ZN) method needs a lot of experience and experiments to ensure the optimal performance. In this paper, CMIA(Cell Mediated Immune Algorithm) controller is proposed to drive the autonomous guided vehicle (AGV) more effectively. The proposed controller is based on specific immune responses of the biological immune system which is the cell mediated immunity. To verify the performance of the proposed CMIA controller, some experiments for the control of steering and speed of that AGV are performed. The tracking error of the AGV is mainly investigated for this purpose. As a result, the capability of realization and reliableness are proved by comparing the response characteristics of the proposed CMIA controllers with those of the conventional PID and NNPID(Neural Network PID) controller.

In the view of oriental medicine, the liver is the general of the army in its function of protecting against the enemy. So this concept is very closely associated to the immunological function. Its relations with immunological function are as follows. 1. The liver produces most of the proteins and converts them with hepatocytes, composes 80% in total reticuloendothelial system with Kuffer cells & endothelial cells and has typical structure of sinusoidal vessels closely related with the blood system. 2. The liver plays an important role in innate immunity with Kuffer cells as well as with the molecules that the liver produces, related to complementary systems. 3. In the embryonic period, the liver is associated with immune associated cell growth and their maturation. After birth, it is associated with removing old red blood cells and with systematically modulating immune system through hormone metabolism. 4. The liver controls the autoimmune disease resulting from immune complex by removing molecules like immune complex. 5. In the processing of blood 19A from the digestive system, the liver has an important role in protecting the body from unnecessary immune responses. 6. In the oriental medical view, liver plays a major role in the immune function by storing blood and dispersing stagnated hepatoqi with the help of the kidneys and spleen.

Coccidiosis, an intestinal infection caused by intracellular protozoan parasites belonging to several different species of Eimeria seriously impairs the growth and feed utilization of livestock and poultry. Due to complex life cycle of organism and intricate host immune responses to Elmeria, coccidia vaccine development has been difficult. Understanding of basic imunobiology of pertinent host-parasite interactions is necessary for the development of novel control strategy. Although chickens infected with Eimeria spp. produce parasite-specific antibodies in both the circulation and mucosal secretions, antibody mediated responses play a minor role in protection gainst coccidiosis. Rather, increasing evidence show that cell-mediated immunity plays a major role in resistance to coccidiosis. T-lymphocytes appear to respond to coccidiosis both through cytokine production and a direct cytotoxic attack on infected cells. The exact mechanisms by which T-cells eliminate the parasites, however, remain to be investigated. Since it is crucial to understand the intestinal immune system in order to develop an immunological control strategy against any intestinal immune system in order to develop an immunological control strategy against any intestinal diseases, this presentation will summarize our current understanding of the avian intestinal immune system and mucosal immune responses to Eimeria, to provide a conceptual overview of the complex molecular and cellular events involved in intestinal immune responses to enteric pathogens.

The CRISPR-Cas system is the adaptive immune system in bacteria and archaea against invading phages or foreign plasmids. In the type II CRISPR-Cas system, an endonuclease Cas9 cleaves DNA targets of phages as directed by guide RNA comprising crRNA and tracrRNA. To avoid targeting and destruction by Cas9, phages employ anti-CRISPR (Acr) proteins that act against host bacterial immunity by inactivating the CRISPR-Cas system. Here we report the backbone $^1H$, $^{15}N$, and $^{13}C$ resonance assignments of AcrIIA4 that inhibits endonuclease activity of type II-A Listeria monocytogenes Cas9 and also Streptococcus pyogenesis Cas9 using triple resonance nuclear magnetic resonance spectroscopy. The secondary structures of AcrIIA4 predicted by the backbone chemical shifts show an ${\alpha}{\beta}{\beta}{\beta}{\alpha}{\alpha}$ fold, which is used to determine the solution structure.

In this paper, we propose an adaptive PID controller using a cell-mediated immune response to improve a PID control performance. The proposed controller is based on the specific immune response of the biological immune system that is cell-mediated immunity. The immune system of organisms in the real body regulates the antibody and the T-cells to protect an attack from the foreign materials like virus, germ cells, and other antigens. It has similar characteristics that are the adaptation and robustness to overcome disturbances and to control the plant of engineering application. We first build a model of the T-cell regulated immune response mechanism and then designed an I-PID controller focusing on the T-cell regulated immune response of the biological immune system. We apply the proposed methodology to building structures to mitigate vibrations due to strong winds for evaluation of control performances. Through computer simulations, system responses are illustrated and additionally compared to traditional control approaches.
