RESUMEN

Blood cell ratios are a standard clinical index for the assessment of inflammation. Although a large number of epidemiological investigations have shown that inflammation is a potential risk factor for the development of coronary heart disease (CHD), there is not sufficient and direct evidence to confirm the relationship between blood cell ratios and CHD. Therefore, this study aimed to elucidate the effect of blood cell ratios on the incidence of coronary heart disease. This 10-year national study included data from 24,924 participants. The independent variable was blood cell ratios, and the dependent variable was coronary heart diseases (yes or no). The relationship between blood cell ratios and coronary heart disease was verified using baseline characteristic analysis, multivariate logistic regression analysis, smoothed fitted curves, and subgroup analysis. This study found that in multiple logistic regression analysis showed significant positive correlation between monocyte counts × meutrophil counts/lymphocyte counts (SIRI) (OR = 1.495; 95% CI = 1.154-1.938), monocyte-lymphocyte ratio (MLR) (OR = 3.081; 95% CI = 1.476-6.433) and the incidence of CHD; lymphocyte-monocyte ratio (LMR) (OR = 0.928;95% CI = 0.873-0.987), monocyte-lymphocyte ratio (PLR) (OR = 0.997;95% CI = 0.994-1.000) showed negative correlation with CHD. The smoothed curve fitting shows a nonlinear relationship between SIRI, LMR, PLR, and CHD, with an inverted U-shaped curve between SIRI and CHD, an L-shaped angle between LMR and CHD, and a U-shaped curve between PLR and CHD, respectively. Their inflection points are 1.462, 3.75, and 185.714, respectively. SIRI has an inverted U-shaped curve with coronary heart disease, suggesting that low levels of SIRI increase the risk of CHD; LMR with an L-shaped curve with CHD, and PLR with a U-shaped curve with CHD, suggesting that the risk of CHD can be prevented when LMR and PLR are reduced to a certain level. This has positive implications for the prevention and treatment of CHD.

RESUMEN

OBJECTIVE: To investigate the clinical significance of the creatine kinase (CK)-MB/total CK ratio, neutrophil/lymphocyte ratio (NLR) and red blood cell distribution width in acute myocardial infarction (AMI). METHODS: A retrospective analysis was conducted of 196 AMI cases from our hospital's cardiology department; healthy people were selected over the same period as the control. The two groups' test indexes were compared through multivariate logistic regression analysis to screen for AMI risk factors; the receiver operating characteristic (ROC) curve was used to evaluate their AMI predictive values. RESULTS: The serum CK, CK-MB, CK index, neutrophils and NLR values in the AMI group were significantly higher compared with those in the control group (p < 0.05); however, the levels of serum lymphocytes were significantly lower compared with those in the control group (p < 0.05). Multivariate logistic regression analysis showed that elevated CK-MB and NLR levels were risk factors for AMI (p < 0.05). The ROC curve showed that the area under the curve of the NLR and CK levels were 0.917 and 0.594, respectively. CONCLUSION: The CK index and NLR have a clinical predicting value for AMI and could be used as a clinical auxiliary diagnostic index for the assessment of patients with AMI.

RESUMEN

BACKGROUND: HCC is a leading cause of cancer-related death. The role of reactive oxygen species (ROS) in HCC remains elusive. Since a primary ROS source is the mitochondrial electron transport chain complex Ι and the NADH:ubiquinone Oxidoreductase Subunit B3 (NDUFB3), a complex I subunit, is critical for complex I assembly and regulates the associated ROS production, we hypothesize that some HCCs progress by hijacking NDUFB3 to maintain ROS homeostasis. METHODS: NDUFB3 in human HCC lines was either knocked down or overexpressed. The cells were then analyzed in vitro for proliferation, migration, invasiveness, colony formation, complex I activity, ROS production, oxygen consumption, apoptosis, and cell cycle. In addition, the in vivo growth of the cells was evaluated in nude mice. Moreover, the role of ROS in the NDUFB3-mediated changes in the HCC lines was determined using cellular and mitochondrion-targeted ROS scavengers. RESULTS: HCC tissues showed reduced NDUFB3 protein expression compared to adjacent healthy tissues. In addition, NDUFB3 knockdown promoted, while its overexpression suppressed, HCC cells' growth, migration, and invasiveness. Moreover, NDUFB3 knockdown significantly decreased, whereas its overexpression increased complex I activity. Further studies revealed that NDUFB3 overexpression elevated mitochondrial ROS production, causing cell apoptosis, as manifested by the enhanced expressions of proapoptotic molecules and the suppressed expression of the antiapoptotic molecule B cell lymphoma 2. Finally, our data demonstrated that the apoptosis was due to the activation of the c-Jun N-terminal kinase (JNK) signaling pathway and cell cycle arrest at G0/G1 phase. CONCLUSIONS: Because ROS plays essential roles in many biological processes, such as aging and cancers, our findings suggest that NDFUB3 can be targeted for treating HCC and other human diseases.

RESUMEN

OBJECTIVE: Children and adolescents with HIV infection are well known to face a heightened risk of tuberculosis. However, the exact mortality rates and temporal trends of those with HIV-tuberculosis (TB) co-infection remain unclear. We aimed to identify the overall mortality and temporal trends within this population. METHODS: PubMed, Web of Science, and Embase were employed to search for publications reporting on the mortality rates of children and adolescents with HIV-TB co-infection from inception to March 2, 2024. The outcome is the mortality rate for children and adolescents with HIV-TB co-infection during the follow-up period. In addition, we evaluate the temporal trends of mortality. RESULTS: During the follow-up period, the pooled mortality was 16% [95% confidence interval (CI) 13-20]. Single infection of either HIV or TB exhibit lower mortality rates (6% and 4%, respectively). We observed elevated mortality risks among individuals aged less than 12 months, those with extrapulmonary TB, poor adherence to ART, and severe immunosuppression. In addition, we observed a decreasing trend in mortality before 2008 and an increasing trend after 2008, although the trends were not statistically significant ( P  = 0.08 and 0.2 respectively). CONCLUSIONS: Children and adolescents with HIV-TB co-infection bear a significant burden of mortality. Timely screening, effective treatment, and a comprehensive follow-up system contribute to reducing the mortality burden in this population.

RESUMEN

Nonalcoholic fatty liver disease (NAFLD) is of global concern due to its high prevalence worldwide. NAFLD, as one of the most common causes of liver function abnormalities, is associated with obesity, insulin resistance, and type 2 diabetes mellitus, and there are no medications available to treat NAFLD. Extracellular vesicles (EVs) are nanosized, membrane-bound vesicles that deliver biomolecules between cells. Exosomes are a subtype of EVs that mediate intercellular communication by delivering proteins and RNAs. MicroRNAs (miRNAs) are a highly conserved class of small tissue-specific non-coding RNAs that influence the expression of many functionally interacting genes. Hepatic-derived exosomal miRNAs are tightly associated with NAFLD occurrence and progression through multiple mechanisms. In addition, the characterization of miRNAs suggests that they may serve as multifunctional biomarkers for NAFLD, be used as clinical therapeutic targets for NAFLD, and be significant predictors of patient prognosis. Here, we review recent advances in the regulation and function of exosome-derived miRNAs in NAFLD, focusing on miRNAs specifically expressed or enriched in hepatocytes (HCs), hepatic macrophages, hepatic stellate cells (HSCs), and other immune cells in the liver. Finally, we discuss future research directions on exosomal miRNAs as biomarkers for NAFLD's diagnosis and clinical therapeutic targets.

RESUMEN

Regulatory T (Treg) cells hold promise for the ultimate cure of immune-mediated diseases. However, how to effectively restore Treg function in patients remains unknown. Previous reports suggest that activated dendritic cells (DCs) de novo synthesize locally high concentrations of 1,25-dihydroxy vitamin D, i.e., the active vitamin D or 1,25(OH)2D by upregulating the expression of 25-hydroxy vitamin D 1α-hydroxylase. Although 1,25(OH)2D has been shown to induce Treg cells, DC-derived 1,25(OH)2D only serves as a checkpoint to ensure well-balanced immune responses. Our animal studies have shown that 1,25(OH)2D requires high concentrations to generate Treg cells, which can cause severe side effects. In addition, our animal studies have also demonstrated that dendritic cells (DCs) overexpressing the 1α-hydroxylase de novo synthesize the effective Treg-inducing 1,25(OH)2D concentrations without causing the primary side effect of hypercalcemia (i.e., high blood calcium levels). This study furthers our previous animal studies and explores the efficacy of the la-hydroxylase-overexpressing DCs in inducing human CD4+FOXP3+regulatory T (Treg) cells. We discovered that the effective Treg-inducing doses of 1,25(OH)2D were within a range. Additionally, our data corroborated that the 1α-hydroxylase-overexpressing DCs synthesized 1,25(OH)2D within this concentration range in vivo, thus facilitating effective Treg cell induction. Moreover, this study demonstrated that 1α-hydroxylase expression levels were pivotal for DCs to induce Treg cells because physiological 25(OH)D levels were sufficient for the engineered but not parental DCs to enhance Treg cell induction. Interestingly, adding non-toxic zinc concentrations significantly augmented the Treg-inducing capacity of the engineered DCs. Our new findings offer a novel therapeutic avenue for immune-mediated human diseases, such as inflammatory bowel disease, type 1 diabetes, and multiple sclerosis, by integrating zinc with the 1α-hydroxylase-overexpressing DCs.

RESUMEN

Background: Ischemic stroke (IS) is a leading cause of long-term disability and even mortality, threatening people's lives. Yinao Fujian (YNFJ) formula is a Traditional Chinese Medicine formula that has been widely used to treat patients with IS. However, the molecular mechanism of YNFJ for the treatment of IS is still elusive. Our study aimed to explore the potential protective effect and the underlying mechanisms of YNFJ on IS using a network pharmacology approach coupled with experimental validation. Materials and methods: Effective compounds of YNFJ were collected from BATMAN-TCM and TCMSP databases, while IS targets were obtained from GeneCards, OMIM, TTD and DrugBank databases. The protein-protein interaction (PPI) network was constructed to further screen the hub targets of YNFJ in IS treatment. GO and KEGG enrichment analyses were used to identify the critical biological processes and signaling pathways of YNFJ for IS. Moreover, Nissl staining, HE, TTC staining and Tunel staining were used in the MCAO model to prove the neuroprotective effect of YNFJ. Oxidative damage, inflammatory factor release and related pathways were tested in MCAO rat model and hypoxia-induced BV2 cell model, respectively. Results: We found that YNFJ treatment significantly alleviated MCAO-induced nerve damage and apoptosis. Then, network pharmacology screening combined with literature research revealed IL6, TNF, PTGS2, NFKBIA and NFE2L2 as the critical targets in a PPI network. Moreover, the top 20 signaling pathways and biological processes associated with the protective effects of YNFJ on IS were enriched through GO and KEGG analyses. Further analysis indicated that NF-κB and Nrf2/HO-1 signaling pathways might be highly involved in the protective effects of YNFJ on IS. Finally, in vitro and in vivo experiments confirmed that YNFJ inhibited the release of inflammatory factors (IL-6 and TNF-α) and MDA content, and increased the activity of SOD. In terms of the mechanism, YNFJ inhibited the release of inflammatory factors by suppressing the NF-κB pathway and decreased the expression of iNOS and COX-2 to protect microglia from inflammation damage. In addition, YNFJ initiated the dissociation of Keap-1 and Nrf2, and activated the downstream protein HO-1, NQO1, thus decreasing oxidative stress. Conclusion: Taken together, the findings in our research showed that the protective effects of YNFJ on IS were mainly achieved by regulating the NF-κB and Nrf2/HO-1 signaling pathways to inhibit oxidative stress damage and inflammatory damage of microglia.

RESUMEN

BACKGROUND: Acute myocardial infarction (AMI) is a common cardiovascular disease worldwide. Circular RNAs (circRNAs) have been shown to exert essential roles in the progression of AMI. However, it remains unclear whether circANKIB1 protects cardiomyocytes from hypoxia-induced injury. OBJECTIVES: The aim of the study was to elucidate the function and mechanisms of circANKIB1 in AMI. MATERIAL AND METHODS: The expression of RNA was estimated using a quantitative real-time polymerase chain reaction (qPCR) assay, and the level of protein was determined with the use of western blot analysis. Methyl thiazolyl tetrazolium (MTT) assay was introduced to test cell viability, and a terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay was used to detect apoptosis. The relative levels of ferrous ion (Fe2+), reactive oxygen species (ROS) and malondialdehyde (MDA) were measured with their corresponding detection kits. The potential target of circANKIB1 and miR-452-5p was predicted using the StarBase database and verified by employing a dual luciferase reporter assay. RESULTS: This study showed a significant decrease in circANKIB1 in hypoxia-treated H9c2 cells. Hypoxic exposure significantly reduced the viability of H9c2 cells and the expression of GPX4, and increased the content of Fe2+, ROS and MDA. These effects were reversed by the overexpression of circANKIB1. Additionally, miR-452-5p was found to be a direct target of circANKIB1, and the miR-452-5p mimic significantly eliminated the protective effect of circANKIB1 overexpression in hypoxia-induced cells. In addition, miR-452-5p could bind to SLC7A11 and negatively regulate its expression. The knockdown of SLC7A11 abolished the effect of circANKIB1 overexpression on hypoxia-induced cardiomyocyte injury. CONCLUSIONS: This investigation revealed for the first time that circANKIB1 regulated signaling of the miR-452-5p/SLC7A11 axis, thereby ameliorating hypoxia-induced cardiomyocyte injury. These findings suggest that circANKIB1 might be a useful adjunct in the treatment of AMI.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: Glycyrrhizae Radix et Rhizoma, a Chinese herb known as licorice, is frequently incorporated in traditional Chinese medicine (TCM) formulations, due to its significant medicinal value and sweet taste. Despite licorice's merits, no systematic scientometric study has yet been conducted to analyze licorice research trends over the past 25 years. AIM OF THE STUDY: We conducted this study with the aim to provide researchers with a comprehensive overview of research advances in the application of licorice as a TCM ingredient and to offer valuable insights to guide future endeavors in this research field. METHODS: We selected licorice-related research papers published between 1997 and 2021 from the Web of Science Core Collection then conducted a scientometric analysis using VOSviewer and CiteSpace software tools. RESULTS: A total of 4883 licorice-related publications, including 4511 research papers, 372 review papers, and their cited references, were included in the analysis. Most of these articles were authored by researchers in China (36.8%), including major contributors Wang Ying, Ye Min, and Zhang Yu. The Journal of Ethnopharmacology (impact factor = 5.4) hosted the greatest number of papers (145 articles). Keyword cluster analysis revealed three keyword categories indicating that current licorice research is focused on licorice quality control and identification of licorice active ingredients and associated pharmacological mechanisms. CONCLUSION: This study provides a comprehensive overview of licorice-related research trends over the past 25 years as based on quantitative and qualitative analyses of published licorice-related articles. The results of this multi-level analysis of licorice research related to TCM formulations, chemical compositions, and pharmacological effects should provide valuable reference data and insights to guide future research endeavors in this field.

RESUMEN

BACKGROUND: The study describes the clinical manifestations and variant screening of two Chinese siblings with primary ciliary dyskinesia (PCD). They carry the same DNAAF2 genotype, which is an extremely rare PCD genotype in the Chinese population. In addition, the study illustrated an overview of published variants on DNAAF2 to date. METHODS: A two-child family was recruited for the study. Clinical manifestations, laboratory tests, bronchoscopic and otoscopic images, and radiographic data were collected. Whole blood was collected from siblings and their parents for whole-exome sequencing (WES) and Sanger sequencing to screen variants. RESULTS: The two siblings exhibited typical clinical manifestations of PCD. Two compound heterozygous variants in DNAAF2 were detected in both by WES. Nonsense variant c.156 C>A and frameshift variant c.177_178insA, which was a novel variant. CONCLUSION: The study identified a novel variant of DNAAF2 in Chinese children with a typical phenotype of PCD, which may enrich our knowledge of the clinical, diagnostic and genetic information of DNAAF2-induced PCD in children.

RESUMEN

Although gemcitabine (GEM) is the first­line drug for advanced pancreatic adenocarcinoma (PAAD), the development of GEM resistance severely limits the effectiveness of this chemotherapy. This study investigated the mechanisms of ecotropic viral integration site 2 A (EVI2A) for resistance to GEM and immune evasion in PAAD. GEM resistance-related biomarkers were predicted using GEO datasets, and GEM-resistant PAAD cells were generated. EVI2A was found expressed highly in GEM-resistant PAAD cells. Gain-of-function analyses revealed that EVI2A encouraged the proliferation and motility of GEM-resistant cells and prevented apoptosis. In addition, EVI2A reduced T cell effector activation. SMYD2 was overexpressed in GEM-resistant cells, and SMYD2 enhanced H3K36me2 modification of EVI2A, thereby promoting EVI2A expression. SMYD2 reduced the sensitivity of GEM-resistant cells, which was reversed by EVI2A knockdown. SMYD2 increased the amount of M2 macrophages (co-cultured with PAAD cells) and decreased T cell effector activation (co-cultured with macrophage supernatant), and the number of M2 macrophages was decreased and T cell effectors were activated following EVI2A knockdown. Our findings indicate that EVI2A, manipulated by the SMYD2-H3K36me2 epigenetic axis, promoted GEM resistance and M2 macrophage-mediated immune evasion in PAAD. Therefore, EVI2A might represent a therapeutic target for overcoming GEM resistance and immunosuppressive environment in PAAD.

RESUMEN

Objective To explore the aptamer specific binding blood group antigen-binding adhesin (BabA) of Helicobacter pylori (H.pylori) for blocking of H.pylori adhering host cell. Methods H.pylori strain was cultured and its genome was extracted as templates to amplify the BabA gene by PCR with designed primers. The BabA gene obtained was cloned and constructed into prokaryotic expression plasmid, which was induced by isopropyl beta-D-galactoside (IPTG) and purified as target. The single stranded DNA (ssDNA) aptamers that specifically bind to BabA were screened by SELEX. Enzyme-linked oligonucleotide assay (ELONA) was used to detect and evaluate the characteristics of candidate aptamers. The blocking effect of ssDNA aptamers on H.pylori adhesion was subsequently verified by flow cytometry and colony counting at the cell level in vitro and in mouse model of infection, respectively. Meanwhile, the levels of cytokines, interleukin 6 (IL-6), IL-8, tumor necrosis factor α (TNF-α), IL-10 and IL-4 in the homogenate of mouse gastric mucosa cells were detected by ELISA. Results The genome of H.pylori ATCC 43504 strains was extracted and the recombinant plasmid pET32a-BabA was constructed. After induction and purification, the relative molecular mass (Mr) of the recombinant BabA protein was about 39 000. The amino acid sequence of recombinent protein was consistent with BabA protein by peptide mass fingerprint (PMF). Five candidate aptamers were selected to bind to the above recombinent BabA protein by SELEX. The aptamers A10, A30 and A42 identified the same site, while A3, A16 and the above three aptamers identified different sites respectively. The aptamer significantly blocked the adhesion of H.pylori in vitro. Animal model experiments showed that the aptamers can block the colonization of H.pylori in gastric mucosa by intragastric injection and reduce the inflammatory response. The levels of IL-4, IL-6, IL-8 and TNF-α in gastric mucosal homogenates in the model group with aptamer treatment were lower than that of model group without treatment. Conclusion Aptamers can reduce the colonization of H.pylori in gastric mucosa via binding BabA to block the adhesion between H.pylori and gastric mucosal epithelial cells.

RESUMEN

Dysregulation of histone deacetylases (HDACs) is closely related to tumor development and progression. As promising anticancer targets, HDACs have gained a great deal of research interests and two decades of effort has led to the approval of five HDAC inhibitors (HDACis). However, currently traditional HDACis, although effective in approved indications, exhibit severe off-target toxicities and low sensitivities against solid tumors, which have urged the development of next-generation of HDACi. This review investigates the biological functions of HDACs, the roles of HDACs in oncogenesis, the structural features of different HDAC isoforms, isoform-selective inhibitors, combination therapies, multitarget agents and HDAC PROTACs. We hope these data could inspire readers with new ideas to develop novel HDACi with good isoform selectivity, efficient anticancer effect, attenuated adverse effect and reduced drug resistance.

RESUMEN

Objective To clarify whether Helicobacter pylori (H. pylori) can promote metastasis of gastric cancer cells via the high-expression of induced B cell specific Moloney murine leukemia virus integration site 1 (Bmi-1). Methods The gastric cancer tissue specimens from 82 patients were collected for this study. The protein and gene expression level of Bmi-1 in gastric adenocarcinoma tissue were detected by immunohistochemistry and real time quantitative PCR, respectively. And meanwhile the correlation between Bmi-1 levels and pathological features, and prognosis of gastric cancer were analyzed retrospectively. Then, the GES-1 cells were transfected with pLPCX-Bmi-1 plasmid and infected with H. pylori respectively. After the Bmi-1 overexpression in GES-1 cells, the invasion ability of the GES-1 cells was detected by Transwell assay, and the cell cycle and apoptosis were detected by flow cytometry. Results The mRNA and protein of Bmi-1 expression in gastric cancer tissues were higher than tumor-adjacent tissue, and the high expression of Bmi-1 was positively correlated with tumor invasion, TNM stage, tumor differentiation, lymph node metastasis and H. pylori infection. When expression of Bmi-1 was up-regulated as a result of H.pylori infection or pLPCX-Bmi-1 transfection, the GES-1 cells had higher invasiveness and lower apoptosis rate with the above treatment respectively. Conclusion H. pylori infection can inhibit the apoptosis of gastric cancer cells and promote their invasion via up-regulating expression of Bmi-1.

RESUMEN

Cerebral ischemic stroke is a high-risk disease and imposes heavy burdens on patients in china. Acupuncture has been used for thousands of years to treat motor dysfunction, cognitive disorder and language barrier caused by cerebral ischemic stroke. Acupoint lines, vertex middle line and anterior oblique line of vertex temple, are always employed to treat cerebral ischemic stroke. However, the mechanism of the two acupoint lines in relieving cerebral ischemic stroke needs further exploration. In the present study, scalp acupuncture treatment alleviated the motor dysfunction, brain damage, and cell death induced by middle cerebral artery occlusion (MCAO) in rats. Proteomics analysis and ultrastructure observation indicated that endoplasmic reticulum and lysosomes might involve in the mechanism of the scalp acupuncture treatment in suppressing MCAO-triggered neural deficits. Effect of the scalp acupuncture treatment on ER stress was then investigated and found that the activation of ER stress mediators, including PERK, IRE1, and ATF6, was downregulated after the scalp acupuncture treatment. Co-localisation analysis of KDEL and CD63 showed that the engulfment of ER fragments by lysosomes was accelerated by the scalp acupuncture treatment. Moreover, expression of pro-apoptotic protein CHOP, phosphorylated-JNK, cleaved capases-3 and -9 also decreased after the scalp acupuncture. In conclusion, the present study showed that scalp acupuncture of vertex middle line and anterior oblique line of vertex temple may alleviate cerebral ischemic stroke by inhibiting ER stress-accelerated apoptosis.

RESUMEN

BACKGROUND: Bilirubin is a potent antioxidant and anti-inflammatory molecule that has been shown to ameliorate airway inflammation. We aimed to study whether serum bilirubin is protective and can predict the development of subsequent recurrent wheezing in infants with severe respiratory syncytial virus (RSV) bronchiolitis. METHODS: The medical records of 188 infants who were hospitalized during an initial episode of severe RSV bronchiolitis at 6 months of age or less were retrospectively reviewed. Our main outcome of interest was the development of subsequent recurrent wheezing by the age of 3 years. Each infant's serum bilirubin concentration was extracted from their blood biochemical results. RESULTS: Seventy-one (37.8%) infants developed recurrent wheezing by the age of 3 and 117 (62.2%) did not. The serum total bilirubin, unconjugated bilirubin, and conjugated bilirubin levels at hospital admission were lower in infants who developed recurrent wheezing as compared to those who did not (p < 0.001). The area under the receiver-operating characteristic curve of serum total bilirubin, unconjugated bilirubin, and conjugated bilirubin for the prediction of subsequent recurrent wheezing were 0.71 (95% confidence interval [CI], 0.64-0.78), 0.70 (95% CI, 0.63-0.78), and 0.67 (95% CI, 0.59-0.75), respectively. Higher admission serum total bilirubin levels were independently associated with a lower risk of development of subsequent recurrent wheezing (adjusted OR 0.17, p < 0.001). CONCLUSION: During the first episode of severe RSV bronchiolitis in infants <6 months of age, moderately higher levels of serum bilirubin are associated with a reduced risk of developing subsequent recurrent wheezing by 3 years of age.

RESUMEN

BACKGROUND: The clinical symptoms of invasive fungal infections (IFI) are nonspecific, and early clinical diagnosis is challenging, resulting in high mortality rates. This study reports the development of a novel aptamer-G-quadruplex/hemin self-assembling color system (AGSCS) based on (1 → 3)-ß-D-glucans' detection for rapid, specific and visual diagnosis of IFI. METHODS: We screened high affinity and specificity ssDNA aptamers binding to (1 → 3)-ß-D-glucans, the main components of cell wall from Candida albicans via Systematic Evolution of Ligands by EXponential enrichment. Next, a comparison of diagnostic efficiency of AGSCS and the (1 → 3)-ß-D-glucans assay ("G test") with regard to predicting IFI in 198 clinical serum samples was done. RESULTS: Water-soluble (1 → 3)-ß-D-glucans were successfully isolated from C. albicans ATCC 10,231 strain, and these low degree of polymerization glucans (< 1.7 kD) were targeted for aptamer screening with the complementary sequences of G-quadruplex. Six high affinity single stranded DNA aptamers (A1, A2, A3, A4, A5 and A6) were found. The linear detection range for (1 → 3)-ß-D-glucans stretched from 1.6 pg/mL to 400 pg/mL on a microplate reader, and the detection limit was 3.125 pg/mL using naked eye observation. Using a microplate reader, the sensitivity and specificity of AGSCS for the diagnosis of IFI were 92.68% and 89.65%, respectively, which was higher than that of the G test. CONCLUSION: This newly developed visual diagnostic method for detecting IFI showed promising results and is expected to be developed as a point-of-care testing kit to enable quick and cost effective diagnosis of IFI in the future.

RESUMEN

BACKGROUND: Trauma has high prevalence rates in populations of people with disabilities, and the effects of traumatic experiences can negatively impact employment. OBJECTIVE: The purpose of this article is to review the existing literature regarding post-traumatic growth (PTG), trauma informed care (TIC), and the conservation of resources (COR) theory. METHOD: We begin with an overview of PTG, TIC, and trauma in relation to disability and employment. Then, we review the personal, condition, object, and energy resources within the COR theory. RESULTS: The remainder of the article focuses on applying PTG and TIC in state-Federal VR programs with a theoretical framework defined by COR. We conceptualize the application in four major VR phases: (a) eligibility determination, (b) rehabilitation plan development, (c) service provision, and (d) job placement. CONCLUSION: By implementing TIC and considering the consumer's resources, VR counselors can help emphasize PTG throughout the process and prioritize PTG as the ultimate goal. The authors provide brief and preliminary implementation recommendations for VR counselors.

RESUMEN

BACKGROUND: Hepatocellular carcinoma (HCC) is aggressive liver cancer. Despite advanced imaging and other diagnostic measures, HCC in a significant portion of patients had reached the advanced stage at the first diagnosis. Unfortunately, there is no cure for advanced HCC. As a result, HCC is still a leading cause of cancer death, and there is a pressing need for new diagnostic markers and therapeutic targets. METHODS: We investigated sulfotransferase 1C2 (SUTL1C2), which we recently showed was overexpressed in human HCC cancerous tissues. Specifically, we analyzed the effects of SULT1C2 knockdown on the growth, survival, migration, and invasiveness of two HCC cell lines, i.e., HepG2 and Huh7 cells. We also studied the transcriptomes and metabolomes in the two HCC cell lines before and after SULT1C2 knockdown. Based on the transcriptome and metabolome data, we further investigated the SULT1C2 knockdown-mediated shared changes, i.e., glycolysis and fatty acid metabolism, in the two HCC cell lines. Finally, we performed rescue experiments to determine whether the inhibitory effects of SULT1C2 knockdown could be rescued via overexpression. RESULTS: We showed that SULT1C2 overexpression promoted the growth, survival, migration, and invasiveness of HCC cells. In addition, SULT1C2 knockdown resulted in a wide range of gene expression and metabolome changes in HCC cells. Moreover, analysis of shared alterations showed that SULT1C2 knockdown significantly suppressed glycolysis and fatty acid metabolism, which could be rescued via SULT1C2 overexpression. CONCLUSIONS: Our data suggest that SULT1C2 is a potential diagnostic marker and therapeutic target for human HCC.
