The low expression of miR‑330‑3p suppressed OS development. It was also noted that circ_0032463 inhibited miR‑330‑3p to upregulate PNN expression. In conclusion, this study confirmed that by regulating the miR‑330‑3p/PNN axis, circular RNA circ_0032463 could function as a tumor enhancer in cells with OS.Endoscopic submucosal dissection (ESD) is an important method for the treatment of early esophageal cancer. However, post-procedure stenosis is one of the most common long-term complications. This meta-analysis aimed to investigate whether stent placement is effective in the stenosis prevention, and which type of stent would be more effective. A systematic and electronic search of clinical trials and observational studies conducted before March 2020 on the efficacy of stent placement in preventing esophageal stricture after ESD was performed. Search terms included "ESD," "esophageal stenosis," "esophageal stricture," and "stents." We conducted a bias risk assessment of the eligible reports and a meta-analysis of the data using Revman 5.3 software. We included two randomized controlled trials (RCTs) and a prospective cohort study involving 163 patients with esophageal mucosal defects encompassing at least three-quarters of the esophagus circumference after ESD. The meta-analysis results showed that post-ESD stenosis rates (RR, 0.37; 95% CI, 0.22-0.64; P = 0.0003) and the number of endoscopic balloon dilations (EBDs) (MD, -1.74; 95% CI, -2.46 to -1.01; P  less then  0.00001) were reduced in the pooled analysis of three studies, indicating that stent placement was effective for stenosis prevention, especially a polyglycolic acid (PGA) sheet combined with stent placement can prevent stenosis (RR, 0.41; 95% CI, 0.23-0.74; P = 0.003) and reduce the number of EBDs (MD, -1.65; 95% CI, -2.40 to -0.90; P  less then  0.0001) significantly. Stent placement can reduce the rate of esophageal stenosis after ESD, especially when stents are covered with PGA sheets. However, more high-quality, low-bias RCTs with a sufficient sample size are needed to demonstrate its effectiveness.There is a gradual telomere shortening due to the inability of the replication machinery to copy the very ends of chromosomes. Additionally, other factors such as high levels of oxidation (free radicals or reactive oxygen species (ROS)), e.g. due to cumulated stress, inflammation or tobacco smoke, accelerate telomere shortening. In humans, the average telomere length is about 10-15 kb at birth and telomeres shorten at a pace of 70 bp per year. However, when cells are exposed to ROS, telomere attrition happens at a faster pace, generating a wide variety of telomere size distribution in different length percentiles, which are different to what is expected just by age. In this work, the generational age of a cell is associated with its telomere length (TL), from certain maximum to the minimal TL that allows replication. In order to study the accumulation of aged granulosa cells in human follicles, from preantral to preovulatory size, a mathematical model is proposed, regarding different degrees of accelerated telomere shortening, which reflect the action of ROS in addition to the telomere shortening that happens after cell division. In cases of cells with TL shorter than cells with average TL, with low telomerase activity and accelerated telomere shortening, the mathematical model predicts an aged outcome in preovulatory follicles. read more The model provides a plausible explanation for what has been observed in oocytes from older women, which have been exposed to ROS for a longer period of time and have bad outcomes after in vitro fertilization.Radiation measurements were conducted at 22 cabinet X-ray systems in Beijing, China, between 2015 and 2019. The median dose rates in the closed-drapes position were 0.11, 0.14, 0.12, 0.14, 0.34 and 0.17 μGy h-1 at the operator position and 5 cm from the surface of the left side, right side, top, entrance and exit, respectively. When a scattering object was passed through the entrance/exit (open-drapes position), the dose rates of eight systems ranged from 1.19 to 6.72 μGy h-1 (median 3.75 μGy h-1). From 2015 to 2019, we monitored the personal dose equivalent Hp (10) 589 times. The personal dose equivalent of three workers exceeded 1 mSv year-1. However, the integrity of equipment shielding needs to be checked regularly to ensure safe operation. The regulation of radiation protection by employers, technician support institutes or government departments is thus warranted to limit the radiation exposure of workers and the public.In this paper, we propose a novel radiochromic film (RCF)-based computed tomography (CT) dosimetry method, which is different from the method based on CT dose index. RCF dosimetry using Gafchromic QA2 films was performed using two lengths of film-folding phantoms. The phantom was exposed to X-ray CT through a single scan, while the RCF was sandwiched between the phantoms. We analysed the dose profile curve in two directions to investigate the dose distribution. We observed a difference in the dose distribution as the phantom size changed. Our results contradict with the results of previous studies such as Monte Carlo simulation or direct measurement. The ability to visually evaluate 2D dose distributions is an advantage of RCF dosimetry over other methods. This research investigated the ability of 2D X-ray CT dose evaluation using RCF and film-folding phantom.
This study aimed to compare real-world clinical effectiveness and safety of vedolizumab, an α4β7-integrin inhibitor, and anti-tumour necrosis factor-α (anti-TNFα) agents in biologic-naïve ulcerative colitis (UC) and Crohn's disease (CD) patients.

This was a 24-month retrospective medical chart study in adult UC and CD patients treated with vedolizumab or anti-TNFα in Canada, Greece and the United States. Inverse probability weighting was used to account for differences between groups. Primary outcomes were cumulative rates of clinical effectiveness (clinical response, clinical remission, mucosal healing) and incidence rates of serious adverse events (SAEs) and serious infections (SIs). Secondary outcomes included cumulative rates of treatment persistence (patients who did not discontinue index treatment during follow-up) and dose escalation and incidence rates of disease exacerbations and disease-related surgeries. Adjusted analyses were performed using inverse probability weighting.

A total of 1095 patients (604 UC, 491 CD) were included.
