In general, participants in our study demonstrated excellent adherence to all social distance measures, considered essential for limiting the spread and progression of COVID-19. However, attitudes regarding reduced physical contact was poor in the Makkah region, which necessitates greater efforts to educate and inform people about the associated risks.Circular RNA carboxypeptidase A4 (circCPA4) has been shown to involve in the tumorigenesis of glioma. However, the function and the molecular mechanism of circCPA4 in glioma remain inadequate. Levels of circCPA4 and microRNA (miR)-760 were detected by quantitative real-time polymerase chain reaction. Cell proliferation, apoptosis, migration, and invasion were analyzed using MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide), colony formation, flow cytometry, and transwell assays, respectively. Western blot was used to detect the protein levels of matrix metallopeptidase 2 (MMP2), MMP9 and myocyte enhancer factor 2D (MEF2D). The interaction between miR-760 and circCPA4 or MEF2D was analyzed by the dual-luciferase reporter assay or RNA pull-down assay. In vivo experiments were conducted using murine xenograft models. this website We found circCPA4 was highly expressed in glioma, and circCPA4 knockdown suppressed tumor cell proliferative, migratory and invasive behaviors, but enhanced cell apoptosis and radiosensitivity in glioma. CircCPA4 directly bound to miR-760 to suppress its expression, and miR-760 inhibition reversed circCPA4 knockdown-mediated inhibition of cell malignant phenotypes in glioma. MEF2D was a target of miR-760, and miR-760 performed anti-tumor effects by targeting MEF2D in glioma cells. Meanwhile, we found circCPA4 could indirectly regulate MEF2D by sponging miR-760. Importantly, xenograft analysis suggested that circCPA4 knockdown impeded tumor growth in vivo via regulating miR-760 and MEF2D. In conclusion, circCPA4 knockdown suppressed cell malignant phenotypes in glioma via miR-760/MEF2D axis to impede the progression of glioma, suggesting potential therapeutic targets for glioma treatment.Oxidative stress plays a pivotal part in the manifestation of neuroinflammation, which further leads to neurodegenerative diseases like Alzheimer's disease (AD). Systemic administration of lipopolysaccharide (LPS) induces neuroinflammation resulting in memory impairment (MI) and cognitive decline. In this study, we evaluated whether prophylactic administration of Rosmarinic acid (RA), a naturally occurring compound, exerts a neuroprotective effect in LPS-induced MI and cognitive decline. Herein, Swiss albino mice were pre-treated with RA (0.5 mg/kg and 1 mg/kg i.p.) for 28 days and were intermittently exposed to LPS (0.25 mg/kg i.p.) for 7 days. LPS caused poor memory retention and increased cognitive decline in Morris water maze (MWM) and Y maze paradigms respectively. Additionally, LPS increased oxidative stress which was denoted by a decrease in superoxide dismutase (SOD) activity, decrease in reduced glutathione (GSH) levels, and increased lipid peroxidation in the brain. Imbalance in the cholinergic system was analyzed by measuring the acetylcholinesterase (AChE) activity. Pre-treatment with RA improved memory and behavioral disturbances by alleviating oxidative stress and AChE activity. LPS augmented levels of tumor necrosis factor (TNF-α), interleukin (IL)-6, caspase-3, and c-Jun. Pre-treatment with RA revitalized the elevated levels of proinflammatory cytokines and apoptotic proteins. In conclusion, this study showcases the amelioration of MI by RA in LPS-challenged memory and cognitive decline, which could be credited to its anti-oxidant effect, inhibitory effect on both proinflammatory cytokines and apoptotic regulators, and reduction in AChE activity.
Local recurrence is the most difficult postoperative challenge and the leading cause of death in patients with retroperitoneal liposarcoma (RLPS). We aimed to establish a postoperative nomogram exclusively focused on RLPS for predicting local recurrence-free survival (LRFS).
A cohort of 124 patients after surgical resection with curative intent in the Peking University Cancer Hospital Sarcoma Center were included in the study. Demographic, clinicopathologic, and treatment variables were analyzed using the Cox regression model. Significant clinically relevant variables in multivariable analysis were incorporated into the RLPS-specific nomogram. The discriminative ability and predictive accuracy of the nomogram were assessed by calculating the concordance index and drawing a calibration plot.
At a median follow-up of 26.5 (interquartile range 10.9-39.4) months, 71 patients had recurrent disease. The 3-year and 5-year LRFS rates were 35.6% (95% confidence interval, 27.0-46.9%) and 28.2% (95% CI 15.8-38.6%), respectively. Multivariate analysis identified the French Federation of Cancer Centers Sarcoma Group (FNCLCC) grade and completeness of resection as independent predictors of LRFS. Variables included in our nomogram were presentation status, multifocality, completeness of resection, histologic subtypes, and FNCLCC grade. The concordance index of our nomogram was 0.732 (95% CI 0.667-0.797) and the calibration plot was excellent.
Our novel nomogram for patients with resected RLPS could improve recurrence risk stratification to explore molecular analysis associated with recurrence.

Worldwide, there has been a growing interest in oncofertility issues. In 2017, the Japanese Society of Clinical Oncology published clinical practice guidelines for fertility preservation (FP) in cancer patients. We conducted a questionnaire survey to explore the FP practices among hematologists before the publication of this guideline.
We sent 427 designated cancer hospitals in Japan a questionnaire about FP treatment for patients with hematological malignancies between January and December 2014.
Of these, 137 institutions responded, and 81 (19.0%) were included in the analysis. A total of 324 female and 441 male patients, aged < 40years, were treated. The percentage of patients informed about FP was higher in patients treated with hematopoietic cell transplant than those without. Female patients were less likely to be informed about FP than male patients. FP was performed in a total of 27 female patients 20 oocyte cryopreservation, 2 embryo cryopreservation, 3 ovarian tissue cryopreservation, and 2 ovarian shielding during total body irradiation.
