The Peripheral Role of CCL2 in the Anti-Nociceptive Effect of Sigma-1 Receptor Antagonist BD1047 on Inflammatory Hyperalgesia in Rats.

Our recent study demonstrated that the CC-chemokine ligand 2 (CCL2) present in primary afferent fibers (PAFs) plays an important role in the microglia-dependent neuronal activation associated with zymosan-induced inflammatory pain. The present study was aimed to evaluate whether BD1047 (a prototypical sigma-1 receptor (Sig-1R) antagonist) is capable of modifying elevated levels of inflammation-evoked CCL2 as a peripheral antinociceptive mechanism. In DRG primary culture, zymosan dose-dependently increased CCL2 release from isolectin B4 (IB4)-positive DRG neurons, a process that was inhibited by co-culture with BD1047.

Questionnaires were distributed to perioperative nurses working in 12 large hospitals in Korea.

Factors Associated With Post-traumatic Growth Among Healthcare Workers Who Experienced the Outbreak of MERS Virus in South Korea: A Mixed-Method Study.

Infectious disease outbreaks such as COVID-19 and MERS pose a major threat to healthcare workers' (HCWs) physical and mental health. Studies exploring the positive changes gained from adapting to traumatic events, known as post-traumatic growth (PTG), have attracted much attention. However, it is unclear which factors or experiences lead to PTG among HCWs.

A qualitative study on the experience of acupuncture treatment in infertile women.

Background: This study aimed to record and analyze the experiences of infertile women who underwent acupuncture treatment.

Methods: This is a qualitative study in which in-depth interviews were conducted with women who underwent acupuncture as a treatment for infertility from the viewpoint of phenomenology, a method of understanding human behavior in the general human and social context, and grasping the nature of the experience in depth. The study participants were 12 women who had been receiving acupuncture treatment for infertility for more than 3 months.

Exosome and Melatonin Additively Attenuates Inflammation by Transferring miR-34a, miR-124, and miR-135b.

The positive effects of mesenchymal stem cells (MSCs) are primarily activated through molecular secretions known as paracrine activity, which regulates the function of various cell types including immune cells. Accumulating evidence shows that exosomes of soluble factors released from MSCs are potential alternative agents for stem cell-based therapy, although the exact underlying mechanism has not been elucidated. The purpose of this study was to evaluate the potential effects of exosomes produced by adipose-derived MSCs and to examine the changes in anti-inflammatory genes in concurrence with the polarization of M2 macrophages in cellular models ex vivo.

Access to antenatal healthcare and the prevalence of oral clefts: a spatial analysis.

Congenital anomalies are caused by a variety of risk factors, including individual and environmental ones. This study estimated the prevalence of oral clefts and examined their area-level risk indicators using data from The National Congenital Anomaly Survey in South Korea. Disease mapping and ecological regression were used to assess the geographical variation and potential risk indicators for oral clefts, such as living in a rural area, material deprivation, and limited access to antenatal healthcare.

The prevalence of insulin refusal and psychological insulin resistance among Korean patients with type 2 diabetes mellitus.

Background: This study investigated the prevalence of insulin refusal and compared the level of psychological insulin resistance (PIR) with the intention to accept insulin therapy among Korean patients with type 2 diabetes.

Methods: Type 2 diabetes patients (n=1,209) were recruited from inner city outpatient diabetes clinics in 2016. Patient demographic, insulin recommendation, diabetes treatment type, intention to receive insulin therapy, and PIR information was collected using self-reports.

Verification of the Korean Version of the Dental Fear Survey.

Background: Although studies on dental fear in relation to sex and age have been conducted, there have been few nationwide studies particularly on the youth sector. In addition, no validity and reliability verifications have been implemented for new research groups on the Korean version of the Dental Fear Survey (K-DFS). Therefore, this study aimed to apply the K-DFS developed in a previous study on Korean youth to draw conclusions on dental fear among the youth.

Current Perspectives regarding Stem Cell-Based Therapy for Alzheimer's Disease.

Alzheimer's disease (AD), a progressive neurodegenerative disorder featuring memory loss and cognitive impairment, is caused by synaptic failure and the excessive accumulation of misfolded proteins. Many unsuccessful attempts have been made to develop new small molecules or antibodies to intervene in the disease's pathogenesis. Stem cell-based therapies cast a new hope for AD treatment as a replacement or regeneration strategy.

Current Perspectives Regarding Stem Cell-Based Therapy for Liver Cirrhosis.

Liver cirrhosis is a major cause of mortality and a common end of various progressive liver diseases. Since the effective treatment is currently limited to liver transplantation, stem cell-based therapy as an alternative has attracted interest due to promising results from preclinical and clinical studies. However, there is still much to be understood regarding the precise mechanisms of action.
