To investigate CD44 effects on the adriamycin-resistant in chronic myelogenous leukaemia cells K562, we explored the role of CD44 in the K562 cells migration and apoptosis.
GeneChip
screening is used for elucidating various chemoresistance-related gene expression in the adriamycin-resistant leukaemia cells K562/ADR. We constructed K562/CD44 cells by transfection of an EGFP-SV40-CD44 plasmid, and adriamycin-resistant ability was confirmed by detecting migration and apoptosis-related proteins and mRNA expression using Western blotting and Real-time PCR respectively.
K562/CD44 cells were generated by the transfection of an EGFP-SV40-CD44 plasmid with high CD44 expression. mRNA expression levels of CD44 and P-glycoprotein (P-gp), along with the proliferation rate, were increased, while the apoptosis rate of K562/CD44 cells was decreased. Migration-associated proteins such as MMP-2 and MMP-9 were upregulated, whereas apoptosis-related protein Bax was downregulated and Bcl-2 protein was not significantly altered in the K562/CD44 cells.
CD44 might be involved in adriamycin resistance via regulation of P-gp, MMP-2, MMP-9, and Bcl-2/Bax.

IL-13 is considered an archetypal T2 cytokine central to the clinical disease expression of asthma. The IL-13 response genes, which are upregulated in central airway bronchial epithelial of asthma patients, can be normalized by high-dose inhaled steroid therapy in severe asthma. However, this is not the case within the peripheral airways. We have sought to further understand IL-13 in the peripheral airways in severe asthma through bronchoalveolar analysis.
Bronchoalveolar lavage samples were collected from 203 asthmatic and healthy volunteers, including 78 with severe asthma. Inflammatory mediators were measured using a multiple cytokine immunoassay platform. This analysis was replicated in a further 59 volunteers, in whom 16S rRNA analysis of BAL samples was undertaken by terminal restriction fragment length polymorphism.
Severe asthma patients with high BAL IL-13, despite treatment with high-dose inhaled corticosteroids, had more severe lung function and significantly higher BAL neutrophil percentages, but not BAL eosinophils than those with normal BAL-13 concentrations. This finding was replicated in the second cohort, which further associated BAL IL-13 and neutrophilia with a greater abundance of potentially pathogenic bacteria in the peripheral airways.
Our findings demonstrate a steroid unresponsive source of IL-13 that is associated with BAL neutrophilia and bacterial dysbiosis in severe asthma. Our findings highlight the biological complexity of severe asthma and the importance of a greater understanding of the innate and adaptive immune responses in the peripheral airways in this disease.

To identify high-risk HPV (hrHPV) genotypes associated with high-grade vaginal intraepithelial neoplasia (VaIN), and evaluate the efficacy of various treatments for high-grade VaIN.
A retrospective review of outcomes among women diagnosed with VaIN after vaginal punch biopsy conducted due to an abnormal Papanicolaou smear or positive test for hrHPV at a hospital in Seoul, Korea, from 2013 to 2018. Logistic regression was used to identify variables associated with abnormal pathologic outcomes.
Among 389 women included in the study, 58 were diagnosed with high-grade VaIN, including VaIN stage 2 (n=37), VaIN stage 3 (n=16), carcinoma in situ of the vagina (n=3), and squamous carcinoma of the vagina (n=2). In multivariate logistic regression analysis, risk of high-grade VaIN and cancer was higher among women with abnormal cytology (odds ratio [OR], 1.88; 95% confidence interval [CI], 1.47-2.47), any hrHPV infection (OR, 8.75; 95% CI, 1.14-67.31), HPV16 infection (OR, 5.71; 95% CI, 2.57-12.68), or HPV31 infection (OR, 4.37; 95% CI, 1.45-13.11).
The findings suggest that infection with hrHPV, especially HPV16 and HPV31, is significantly associated with high-grade VaIN. Regarding treatment modalities, ablative or excisional treatments showed good efficacy against pathologic regression of high-grade VaIN.

However, opportunities remain to further optimize pediatric medicine developments, notably in relation to the implementation of the regulatory framework. This paper therefore describes bottlenecks identified by industry that occur during the medicinal development process, including those relating to the scientific advice process, pediatric investigation plan (PIP) development, compliance checks, and study submissions, and offers some considerations and insights to address these. Considerations, which are workable within the current legislative framework, focus on an integrated scientific discussion, optimization of PIP procedures and compliance checks, and an alignment of study-reporting requirements.Focal articular cartilage damage can eventually lead to the onset of osteoarthritis with degradation around healthy articular cartilage. Currently, there are no drugs available that effectively repair articular cartilage damage. Several surgical techniques exist and are expected to prevent progression to osteoarthritis, but they do not offer a long-term clinical solution. Recently, regenerative medicine approaches using human pluripotent stem cells (PSCs) have gained attention as new cell sources for therapeutic products. To translate PSCs to clinical application, appropriate cultures that produce large amounts of chondrocytes and hyaline cartilage are needed. read more So too are assays for the safety and efficacy of the cellular materials in preclinical studies including animal transplantation models. To confirm safety and efficacy, transplantation into the subcutaneous space and articular cartilage defects have been performed in animal models. All but one study we reviewed that transplanted PSC-derived cellular products into articular cartilage defects found safe and effective recovery. However, for most of those studies, the quality of the PSCs was not verified, and the evaluations were done with small animals over short observation periods. Large animals and longer observation times are preferred. We will discuss the recent progress and future direction of the animal transplantation studies for the treatment of focal articular cartilage damages using PSCs.
This study aimed to evaluate the effectiveness of probiotics in treating children with acute diarrhoea and dehydration.
Medline, EMBASE, and the Cochrane Library databases were searched for relevant studies and statistical analysis was performed.
A total of 17 randomised controlled trials (RCTs) involving 2861 participants met the inclusion criteria. Compared with placebo, probiotics reduced the duration of diarrhoea (12 RCTs [15, 17], n = 1907, mean difference - 21.33 h, confidence interval (CI) -29.74 to -12.91, high heterogeneity, I
= 86%), the duration of hospitalisation when compared with placebo (eight RCTs [19, 20], n = 1606, mean difference - 0.83 days, CI -1.53 to -0.12, high heterogeneity, I
= 96%) and reduced risk of diarrhoea on day 4 or more days (six RCTs [19, 20], n = 1093, risk difference - 0.13, 95% CI -0.17- -0.09, no heterogeneity).
Probiotics alongside rehydration therapy appear to be safe and have clear beneficial effects in shortening the duration of diarrhoea in children with acute diarrhoea and dehydration.

The aim of the present study was to investigate the expression profiles of circular RNAs (circRNAs) in the pericystic tissue of patients with cystic echinococcosis (CE).
CircRNA expression profiles were obtained by circRNA microarray of four matched pairs of pericystic tissues affected by CE and adjacent normal liver tissues. qRT-PCR was used to validate the differential expression of some circRNAs identified by the microarray analysis. The potential functions of the differentially expressed circRNAs in the CE pericystic tissues were predicted by bioinformatic analysis.
Compared with the adjacent normal liver tissues, 177 circRNAs were upregulated and 166 circRNAs were downregulated in CE pericystic tissues based on a ≥2.0-fold change. The top 10 upregulated circRNAs were hsa_circRNA_001654,hsa_circRNA_103361,hsa_circRNA_001490,hsa_circRNA_104310,hsa_circRNA_100395,hsa_circRNA_102485,hsa_circRNA_001459,hsa_circRNA_104193,hsa_circRNA_400043, and hsa_circRNA_006773; The top 10 downregulated circRNAs were targets.
Differential expression of circRNAs may be associated with the development and progression of CE, and these circRNAs might be useful as biomarkers for prognosis prediction and as treatment targets.The optimal partitioning theory predicts that plants of a given species acclimate to different environments by allocating a larger proportion of biomass to the organs acquiring the most limiting resource. Are similar patterns found across species adapted to environments with contrasting levels of abiotic stress? We tested the optimal partitioning theory by analysing how fractional biomass allocation to leaves, stems and roots differed between woody species with different tolerances of shade and drought in plants of different age and size (seedlings to mature trees) using a global dataset including 604 species. No overarching biomass allocation patterns at different tolerance values across species were found. Biomass allocation varied among functional types as a result of phenological (deciduous vs evergreen broad-leaved species) and broad phylogenetical (angiosperms vs gymnosperms) differences. Furthermore, the direction of biomass allocation responses between tolerant and intolerant species was often opposite to that predicted by the optimal partitioning theory. We conclude that plant functional type is the major determinant of biomass allocation in woody species. We propose that interactions between plant functional type, ontogeny and species-specific stress tolerance adaptations allow woody species with different shade and drought tolerances to display multiple biomass partitioning strategies.One challenge of conducting intervention studies is ensuring that study participants are exposed to the intervention. For example, in our randomized controlled trial of Take Charge!, a mentor-implemented and research-informed violence prevention program that partners with one-on-one community-based mentoring agencies, only 50% of intervention youth with fight-related injuries were successfully matched with a mentor. We examined the differences between matched (n = 49) and unmatched (n = 49) youth with regard to demographics, time from injury to study enrollment, perceived seriousness of injury, belief that future injury can be avoided, and household chaos. Youth who were successfully matched with a mentor were more likely to perceive the injury as very serious or somewhat serious compared with unmatched youth (95.9% vs. 79.6%, p = .028). All other factors were not significantly associated with successful mentor matching. Future violence prevention interventions should consider youth perceptions as a factor that may influence the completion of desired interventions.
