RESUMO
INTRODUCTION: Neurogenesis in the adult brain may play an important role in memory and cognition; however, knowledge of neurogenic markers in the human brain remains limited. We compared the single-nucleus transcriptome of the hippocampus with that of other cortical regions to identify hippocampus-specific neurogenic markers. METHODS: We analyzed 26,189 nuclei from four human brains collected within 16 hours of death. Clustering and annotation were performed to examine differential expression, gene ontology, and intercellular communication. DCX expression was validated by droplet ddPCR. RESULTS: Immature markers such as DCX, CALB2, NES, SOX2, PAX6, DPYSL3 and TUBB3 were expressed in both hippocampus and prefrontal cortex, with higher levels in the prefrontal cortex. ddPCR confirmed higher expression of DCX in the prefrontal cortex. DCX was involved in both neurogenesis and neuroprotection pathways. CONCLUSION: Neurogenic markers are not definitive indicators of adult neurogenesis, as their roles are more complex than previously understood.
RESUMO
Rheumatoid arthritis (RA) is an autoimmune disease of the joint synovial membranes. RA is difficult to prevent or treat; however, blocking proinflammatory cytokines is a general therapeutic strategy. Pulsed electromagnetic field (PEMF) is reported to alleviate RA's inflammatory response and is being studied as a non-invasive physical therapy. In this current study, PEMF decreased paw inflammation in a collagen-induced arthritis (CIA) murine model. PEMF treatment at 10 Hz was more effective in ameliorating arthritis than at 75 Hz. In the PEMF-treated CIA group, the gross inflammation score and cartilage destruction were lower than in the untreated CIA group. The CIA group treated with PEMF also showed lower serum levels of IL-1ß but not IL-6, IL-17, or TNF-α. Serum levels of total anti-type II collagen IgG and IgG subclasses (IgG1, IgG2a, and IgG2b) remained unchanged. In contrast, tissue protein levels of IL-1ß, IL-6, TNF-α, receptor activator of nuclear factor kappa-Β (RANK), RANK ligand (RANKL), IL-6 receptor (IL-6R), and TNF-α receptor1 (TNFR1) were all lower in the ankle joints of the PEMF-treated CIA group compared with the CIA group. The results of this study suggest that PEMF treatment can preserve joint morphology cartilage and delay the occurrence of CIA. PEMF has potential as an effective adjuvant therapy that can suppress the progression of RA.

Enterotoxigenic Bacteroides fragilis (ETBF) causes colitis and is implicated in inflammatory bowel diseases and colorectal cancer. The ETBF-secreted B. fragilis toxin (BFT) causes cleavage of the adherence junction, the E-cadherin, resulting in the large intestine showing IL-17A inflammation in wild-type (WT) mice. However, intestinal pathology by ETBF infection is not fully understood in B-cell-deficient mice. In this study, ETBF-mediated inflammation was characterized in B-cell-deficient mice (muMT). WT or muMT C57BL/6J mice were orally inoculated with ETBF and examined for intestinal inflammation. The indirect indicators for colitis (loss of body weight and cecum weight, as well as mortality) were increased in muMT mice compared to WT mice. Histopathology and inflammatory genes (Nos2, Il-1ß, Tnf-α, and Cxcl1) were elevated and persisted in the large intestine of muMT mice compared with WT mice during chronic ETBF infection. However, intestinal IL-17A expression was comparable between WT and muMT mice during infection. Consistently, flow cytometry analysis applied to the mesenteric lymph nodes showed a similar Th17 immune response in both WT and muMT mice. Despite elevated ETBF colonization, the ETBF-infected muMT mice showed no histopathology or inflammation in the small intestine. In conclusion, B cells play a protective role in ETBF-induced colitis, and IL-17A inflammation is not attributed to prompted colitis in B-cell-deficient mice. Our data support the fact that B cells are required to ameliorate ETBF infection-induced colitis in the host.

Mesenchymal stem cells (MSCs) regulate immune cell activity by expressing tumor necrosis factor-α (TNF-α)-stimulated gene 6 (TSG-6) in inflammatory environments; however, whether anti-inflammatory responses affect TSG-6 expression in MSCs is not well understood. Therefore, we investigated whether transforming growth factor-ß (TGF-ß) regulates TSG-6 expression in adipose tissue-derived stem cells (ASCs) and whether effective immunosuppression can be achieved using ASCs and TGF-ß signaling inhibitor A83-01. TGF-ß significantly decreased TSG-6 expression in ASCs, but A83-01 and the p38 inhibitor SB202190 significantly increased it. However, in septic C57BL/6 mice, A83-01 further reduced the survival rate of the lipopolysaccharide (LPS)-treated group and ASC transplantation did not improve the severity induced by LPS. ASC transplantation alleviated the severity of sepsis induced by LPS+A83-01. In co-culture of macrophages and ASCs, A83-01 decreased TSG-6 expression whereas A83-01 and SB202190 reduced Cox-2 and IDO-2 expression in ASCs. These results suggest that TSG-6 expression in ASCs can be regulated by high concentrations of pro-inflammatory cytokines in vitro and in vivo, and that A83-01 and SB202190 can reduce the expression of immunomodulators in ASCs. Therefore, our data suggest that co-treatment of ASCs with TGF-ß or p38 inhibitors is not adequate to modulate inflammation.

Cultured human skeletal-muscle satellite cells have properties of mesenchymal stem cells (skeletal muscle satellite cell-derived mesenchymal stem cells, SkMSCs) and play anti-inflammatory roles by secreting prostaglandin E2 and hepatocyte growth factor (HGF). To evaluate the utility of SkMSCs in treating liver diseases, we determined whether SkMSCs could ameliorate acute liver and gut inflammation induced by binge ethanol administration. Binge drinking of ethanol led to weight loss in the body and spleen, liver inflammation and steatosis, and increased serum ALT and AST levels (markers of liver injury), along with increased IL-1ß, TNF-α, and iNOS expression levels in mice. However, levels of these binge-drinking-induced indicators were reduced by a single intraperitoneal treatment of SkMSCs. Furthermore, levels of bacteria-derived lipopolysaccharide decreased in the livers and sera of ethanol-exposed mice after SkMSC administration. SkMSCs decreased the extent of tissue inflammation and reduced villus and crypt lengths in the small intestine after alcohol binge drinking. SkMSCs also reduced the leakage of blood albumin, an indicator of leaky gut, in the stool of ethanol-exposed mice. Alcohol-induced damage to human colonic Caco-2/tc7 cells was also alleviated by HGF. Therefore, a single treatment with SkMSCs can attenuate alcoholic liver damage by reducing inflammatory responses in the liver and gut, suggesting that SkMSCs could be used in cell therapy to treat alcoholic liver diseases.

Despite advances in medicine, mortality due to sepsis has not decreased. Pulsed electromagnetic field (PEMF) therapy is emerging as an alternative treatment in many inflammation-related diseases. However, there are few studies on the application of PEMF therapy to sepsis. In the current study, we examined the effect of PEMF therapy on a mouse model of lipopolysaccharide (LPS)-induced septic shock. Mice injected with LPS and treated with PEMF showed higher survival rates compared with the LPS group. The increased survival was correlated with decreased levels of pro-inflammatory cytokine mRNA expression and lower serum nitric oxide levels and nitric oxide synthase 2 mRNA expression in the liver compared with the LPS group. In the PEMF + LPS group, there was less organ damage in the liver, lungs, spleen, and kidneys compared to the LPS group. To identify potential gene targets of PEMF treatment, microarray analysis was performed, and the results showed that 136 genes were up-regulated, and 267 genes were down-regulated in the PEMF + LPS group compared to the LPS group. These results suggest that PEMF treatment can dramatically decrease septic shock through the reduction of pro-inflammatory cytokine gene expression. In a clinical setting, PEMF may provide a beneficial effect for patients with bacteria-induced sepsis and reduce septic shock-induced mortality.

Chronic inflammation has been linked to colitis-associated colorectal cancer in humans. The human symbiont enterotoxigenic Bacteroides fragilis (ETBF), a pro-carcinogenic bacterium, has the potential to initiate and/or promote colorectal cancer. Antibiotic treatment of ETBF has shown promise in decreasing colonic polyp formation in murine models of colon cancer. However, there are no reported natural products that have shown efficacy in decreasing polyp burden. In this study, we investigated the chemopreventive effects of oral administration of zerumbone in ETBF-colonized mice with azoxymethane (AOM)/dextran sulfate sodium (DSS)-induced tumorigenesis. Zerumbone significantly reduced the severity of disease activity index (DAI) scores as well as several parameters of colonic inflammation (i.e., colon weight, colon length, cecum weight and spleen weight). In addition, inflammation of the colon and cecum as well as hyperplasia was reduced. Zerumbone treatment significantly inhibited colonic polyp numbers and prevented macroadenoma progression. Taken together, these findings suggest that oral treatment with zerumbone inhibited ETBF-promoted colon carcinogenesis in mice indicating that zerumbone could be employed as a promising protective agent against ETBF-mediated colorectal cancer.

Enterotoxigenic Bacteroides fragilis (ETBF) is human intestinal commensal bacterium and a potent initiator of colitis through secretion of the metalloprotease Bacteroides fragilis toxin (BFT). BFT induces cleavage of E-cadherin in colon cells, which subsequently leads to NF-κB activation. Zerumbone is a key component of the Zingiber zerumbet (L.) Smith plant and can exhibit anti-bacterial and anti-inflammatory effects. However, whether zerumbone has anti-inflammatory effects in ETBF-induced colitis remains unknown. The aim of this study was to determine the anti-inflammatory effect of orally administered zerumbone in a murine model of ETBF infection. Wild-type C57BL/6 mice were infected with ETBF and orally administered zerumbone (30 or 60 mg/kg) once a day for 7 days. Treatment of ETBF-infected mice with zerumbone prevented weight loss and splenomegaly and reduced colonic inflammation with decreased macrophage infiltration. Zerumbone treatment significantly decreased expression of IL-17A, TNF-α, KC, and inducible nitric oxide synthase (iNOS) in colonic tissues of ETBF-infected mice. In addition, serum levels of KC and nitrite was also diminished. Zerumbone-treated ETBF-infected mice also showed decreased NF-κB signaling in the colon. HT29/C1 colonic epithelial cells treated with zerumbone suppressed BFT-induced NF-κB signaling and IL-8 secretion. However, BFT-mediated E-cadherin cleavage was unaffected. Furthermore, zerumbone did not affect ETBF colonization in mice. In conclusion, zerumbone decreased ETBF-induced colitis through inhibition of NF-κB signaling.

In this study, using immunohistochemistry with fresh cadavers, deliberate histological profiling was performed to determine which fibers are predominant within each compartment. To verify the fascial compartmentation of the SSC and elucidate its histological components of type I and II fibers using macroscopic, histological observation and cadaveric simulation for providing an anatomical reference of efficient injection of the BoNT into the SSC. Seven fixed and three fresh cadavers (six males and four females; mean age, 82.5 years) were used in this study. The dissected specimens revealed a distinct fascia demarcating the SSC into the superior and inferior compartments. The Sihler's staining revealed that the upper and lower subscapular nerves (USN and LSN) innervated the SSC, with two territories distributed by each nerve, mostly corresponding to the superior and inferior compartments of the muscle, although there were some tiny communicating twigs between the USN and LSN. The immunohistochemical stain revealed the density of each type of fiber. Compared with the whole muscle area, the densities of the slow-twitch type I fibers were 22.26 ± 3.11% (mean ± SD) in the superior and 81.15 ± 0.76% in the inferior compartments, and the densities of the fast-twitch type II fiber were 77.74% ± 3.11% in the superior and 18.85 ± 0.76% in the inferior compartments. The compartments had different proportions of slow-fast muscle fibers, corresponding to the functional differences between the superior compartment as an early-onset internal rotator and the inferior compartment as a durable stabilizer of the glenohumeral joint.

Liver organoids generated with single or multiple cell types have been used to investigate liver fibrosis development, toxicity, pathogenesis, and drug screening. However, organoid generation is limited by the availability of cells isolated from primary tissues or differentiated from various stem cells. To ensure cell availability for organoid formation, we investigated whether liver organoids could be generated with cell-line-based Huh-7 hepatocellular carcinoma cells, macrophages differentiated from THP-1 monocytes, and LX-2 hepatic stellate cells (HSCs) and primary liver sinusoidal endothelial cells (LSECs). In liver organoids, hepatocyte-, LSEC-, macrophage-, and HSC-related gene expression increased relative to that in two-dimensional (2D)-cultured Huh-7/LSEC/THP-1/LX-2 cells without Matrigel. Thioacetamide (TAA) increased α-smooth muscle actin expression in liver organoids but not in 2D-cultured cells, whereas in TAA-treated organoids, the expression of hepatic and LSEC markers decreased and that of macrophage and HSC markers increased. TAA-induced fibrosis was suppressed by treatment with N-acetyl-L-cysteine or tumor-necrosis-factor-stimulated gene 6 protein. The results showed that liver toxicants could induce fibrotic and inflammatory responses in liver organoids comprising Huh-7/LSEC/macrophages/LX-2 cells, resulting in fibrotic liver organoids. We propose that cell-line-based organoids can be used for disease modeling and drug screening to improve liver fibrosis treatment.

BACKGROUND: A precise anatomical understanding of the adductor canal (AC) and its neural components is essential for discerning the action mechanism of the AC block. We therefore aimed to clarify the detailed anatomy of the AC using micro-computed tomography (micro-CT), histological evaluation, and immunofluorescence (IF) assays. METHODS: Gross dissections of 39 thighs provided morphometric data relevant to injection landmarks. Serial sectional images of the AC were defined using micro-CT and ultrasonography. The fascial and neural structures of the AC proper were histologically evaluated using Masson's trichrome and Verhoeff-Van Gieson staining, and double IF staining using choline acetyltransferase (ChAT) and neurofilament 200 antibodies. RESULTS: The posteromedial branch insertion of the nerve to vastus medialis (NVM) into the lateral border of the AC proper was lower (14.5 ± 2.4 cm [mean ± SD] above the base of the patella) than the origin of the proximal AC. The AC consists of a thin subsartorial fascia in the proximal region and a thick aponeurosis-like vastoadductor membrane in the distal region. In the proximal AC, the posteromedial branch of the NVM (pmNVM) consistently contained both sensory and motor fibers, and more ChAT-positive fibers were observed than in the saphenous nerve (27.5 ± 11.2 / 104 vs. 4.2 ± 2.6 / 104 [counts/µm2], P < 0.001). CONCLUSIONS: Anatomical differences in fascial structures between the proximal and distal AC and a mixed neural component of the neighboring pmNVM have been visualized using micro-CT images, histological evaluation, and IF assays.

Enterotoxigenic Bacteroides fragilis (ETBF) has emerged as a gut microbiome pathogen that can promote colitis associated cancer in humans. ETBF secretes the metalloprotease, B. fragilis toxin (BFT), which can induce ectodomain cleavage of E-cadherin and IL-8 secretion through the ß-catenin, NF-κB, and MAPK pathways in intestinal epithelial cells. However, it is still unclear whether E-cadherin cleavage is required for BFT induced IL-8 secretion and the relative contribution of these signaling pathways to IL-8 secretion. Using siRNA knockdown and CRISPR knockout studies, we found that E-cadherin cleavage is required for BFT mediated IL-8 secretion. In addition, genetic ablation of ß-catenin indicates that ß-catenin is required for the BFT induced increase in transcriptional activity of NF-κB, p65 nuclear localization and early IL-8 secretion. These results suggest that BFT induced ß-catenin signaling is upstream of NF-κB activation. However, despite ß-catenin gene disruption, BFT still activated the MAPK pathway, suggesting that the BFT induced activation of the MAPK signaling pathway is independent from the E-cadherin/ß-catenin/NF-κB pathway. These findings show that E-cadherin and ß-catenin play a critical role in acute inflammation following ETBF infection through the inflammatory response to BFT in intestinal epithelial cells.
RESUMO
The radiological image of an intact tectorial membrane (TM) became an important favorable prognostic factor for craniovertebral instability. This study visualized the fascial layers of the TM and adjacent connective tissues with clinical significance by micro-CT and histological analysis. The TM firmly attached to the bony surface of the clivus, traversed the atlantoaxial joint posteriorly, and was inserted to the body of the axis showing wide distribution on the craniovertebral junction. The supradental space between the clivus, dens of the axis, anterior atlantooccipital membrane, and the TM contained profound venous networks within the adipose tissues. At the body of the axis, the compact TM layer is gradually divided into multiple layers and the deeper TM layers reached the axis while the superficial layer continued to the posterior longitudinal ligament of the lower vertebrae. The consistent presence of the fat pad and venous plexus in the supradental space and firm stabilization of the TM on the craniovertebral junction was demonstrated by high-resolution radiologic images and histological analysis. The evaluation of the TM integrity is a promising diagnostic factor for traumatic craniovertebral dislocation.

This study aimed to identify the moderating and mediating effect of emotional self-disclosure between depression and quality of life for women under infertility treatment. The subjects included 169 infertile women under in vitro fertilization (IVF) treatment. The data were collected by self-administered questionnaires from June to August in 2019. The questionnaire consisted of questions about depression, emotional self-disclosure, and fertility quality of life. Descriptive statistics, t-tests, one-way analysis of variance, correlation, and stepwise multiple regression were analyzed using the SPSS 25.0 Windows program. Depression had a negative correlation with emotional self-disclosure (r = -0.189, p = 0.014) and fertility quality of life (r = -0.532, p < 0.001). Emotional self-disclosure had a positive correlation with fertility quality of life (r = 0.259, p = 0.001). These results confirm that emotional self-disclosure has mediating effects between depression and fertility quality of life. Therefore, nursing interventions for IVF patients need to encourage expressing and sharing various emotions experienced through the diagnosis and treatment of infertility in order to alleviate negative emotions.

BACKGROUND/AIM: Mesenchymal stem cell-based tumor therapy is still limited due to the insufficient secretion of effectors and discrepancies between their in vitro and in vivo efficacy. We investigated whether genetically engineered adipose tissue-derived mesenchymal stem cells (ASCs) overexpressing tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) had inhibitory effects on H460 tumor growth both in vitro and in an H460 xenograft model. MATERIALS AND METHODS: Genetically engineered adipose tissue-derived mesenchymal stem cells (ASCs) overexpressing tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) were obtained from plasmid transfection with pCMV3-TRAIL and -interferon (IFN)-ß (producing ASC-TRAIL and ASC-IFN-ß, respectively). Death of H460 cells co-cultured with ASCs, ASC-TRAIL, and ASC-IFN-ß or exposed to their conditioned medium was evaluated via apoptosis and cytotoxicity assays. In addition, in an H460 xenograft model (n=10 per group), the antitumor potential of TRAIL-overexpressing, and IFN-ß-overexpressing ASCs was investigated. RESULTS: Conditioned medium obtained from ASC-IFN-ß increased apoptosis of H460 cells more than did ASC-TRAIL. Additionally, in H460 xenograft models, while native ASCs promoted tumor growth, ASC-TRAIL and ASC-IFN-ß both dramatically suppressed tumor growth. Interestingly, in the context of ASC-IFN-ß, tumors were detected only in 20% of nude mice, with smaller sizes and lower weights than those of the control group. CONCLUSION: TRAIL-overexpressing ASCs can be used to treat tumors; ASC-IFN-ß in particular secrete a higher level of TRAIL.

This study aimed to develop an emotion management program for late adolescent males, and investigate the effect of the program. This study is an experimental study using a pretest-posttest control group design. It was conducted from 14 May to 21 December, 2018 at a male high school in Korea. It analyzed 52 participants (26 in the experimental group and 26 in the control group.) Regarding subjective happiness, there was a significant difference between groups (t = 3.409, p = 0.001). In anger control ability and gratitude, there was no significant difference between groups (t = 0.332, p = 0.740/ z = 0.528, p = 0.599). This program for emotion management, which is based on the broaden-and-build theory, can improve subjective happiness, anger control ability, and gratitude, by reinforcing appreciation skills and anger awareness and self-expression in male high school students.

Purpose: This study attempts to explore the experiences of infertility among women with male factor infertility. Methods: From April to July 2018, nine women with experience of male factor infertility and assistant reproductive technology were interviewed. The transcribed data were qualitatively analyzed to identify major themes and sub-themes representing participants' experiences with male factor infertility. Results: The analysis indicated that the women's infertility experiences were structured into five theme clusters: "Difficult to accept the situation", "Confused inside", "Destroyed relationships due to blaming and anger", "Desire social support", and "Embracing hurt feelings and regaining strength". Conclusions: Intervention programs are needed to closely investigate the psychological status of women with male factor infertility and help with their physical and psychological well-being. Efforts to address infertility through effective governmental support for infertility, a strategy for promoting the social recognition of infertility, and the health professional's persistent interest and collaboration, are discussed.

PURPOSE: As the number of infertile couples has grown, many infertile women have experienced depression during the diagnosis and treatment of their infertility. This study aimed to identify the factors related to depression in infertile women who underwent reproductive treatments. METHODS: The study subjects were 149 infertile women who underwent reproductive treatments. The data were collected by self-administered questionnaires from August 1 to December 24, 2018. The questionnaire consisted of questions about fatigue, health-promoting behavior, and depression. Analyses of the descriptive statistics, t-tests, one-way analysis of variance, correlation, and multiple regression were conducted using the SPSS 25.0 Windows program. RESULTS: Thirty-six of the women in the study (24.2%) were in the probably depressed group and 113 (75.8%) were in the definitely depressed group and 100% of the subjects experienced symptoms of depression. Depression was positively correlated with fatigue and negatively correlated with health-promoting behavior. Multiple regression analysis revealed that fatigue and interpersonal relationships were factors significantly related to depression in the model (p<.001), with an explanatory power of 42.6%. CONCLUSION: The results confirmed that fatigue and interpersonal relationships, which is a subfactor of health-promoting behavior, were factors related to depression. To alleviate depression in infertile women, efforts should be made to identify and reduce psychological and physical fatigue. In addition, minimizing relational difficulties that they experience during an infertility diagnosis and treatment and strengthening positive interpersonal relationships can be positive strategies to alleviate depression.
RESUMO
PURPOSE: The purpose of this study was to explore essences and meaning in experiences of women who have had spontaneous abortion. METHODS: A phenomenological methodology was used for the study. A total of five women with the spontaneous abortion participated in the study. In-depth interviews were done for data collection, and the data were analyzed using Colaizzi's method. RESULTS: Five theme clusters, along with 32 sub-themes and 13 themes. The five theme clusters were: 'Waiting and expecting pregnancy', 'Desire to overcome the spontaneous abortion', 'My baby makes me cry and laugh', 'My precious baby', and 'Want to hear with sympathy and talk with you'. CONCLUSION: The women who have had the spontaneous abortion experiences can prevent potential physical and psychological complications after miscarriage by getting education and intervention in nursing. Moreover, they may experience that negative factors of the spontaneous abortion can be turned into positive things through emotional support of family and medical teams.
