Abstract As a common malignant tumor among women, ovarian cancer poses a serious threat to their health. This study demonstrates that long non-coding RNA NRSN2-AS1 is over-expressed in ovarian cancer tissues using patient sample and tissue microarrays. In addition, NRSN2-AS1 is shown to promote ovarian cancer cell proliferation and metastasis both in vitro and in vivo. Mechanistically, NRSN2-AS1 stabilizes protein tyrosine kinase 2 (PTK2) to activate the β-catenin pathway via repressing MG-53-mediated ubiquitinated degradation of PTK2, thereby facilitating ovarian cancer progression. Rescue experiments verify the function of the NRSN2-AS1/PTK2/β-catenin axis and the effects of MG53 on this axis in ovarian cancer cells. In conclusion, this study demonstrates the key role of the NRSN2-AS1/PTK2/β-catenin axis for the first time and explores its potential clinical applications in ovarian cancer.

With the advancements in Web of Things, Artificial Intelligence, and other emerging technologies, there is an increasing demand for artificial visual systems to perceive and learn about external environments. However, traditional sensing and computing systems are limited by the physical separation of sense, processing, and memory units that results in the challenges such as high energy consumption, large additional hardware costs, and long latency time. Integrating neuromorphic computing functions into the sensing unit is an effective way to overcome these challenges. Therefore, it is extremely important to design neuromorphic devices with sensing ability and the properties of low power consumption and high switching speed for exploring in-sensor computing devices and systems. In this review, we provide an elementary introduction to the structures and properties of two common optoelectronic materials, perovskites and transition metal dichalcogenides (TMDs). Subsequently, we discuss the fundamental concepts of neuromorphic devices, including device structures and working mechanisms. Furthermore, we summarize and extensively discuss the applications of perovskites and TMDs in in-sensor computing. Finally, we propose potential strategies to address challenges and offer a brief outlook on the application of optoelectronic materials in term of in-sensor computing.

Objective To explore the association between gallstones and CVD among ethnic minority populations in Guizhou Province, as well as the mediating effect of glomerular filtration rate (GFR) in this association, in order to provide reference suggestions for reducing the burden of CVD. Methods Based on the database of Cohort Study of Native Natural Population in Ethnic Minority Gathering Areas in Southwest China, stratified and multi-stage cluster sampling was used to conduct a baseline survey of ethnic minorities aged 30 - 79 years in Qiandongnan and Qiannan Prefectures of Guizhou Province from 2018 to 2019. Multivariate logistic regression was used to analyze the association between gallstones and CVD, and the mediating effect model was used to evaluate the mediating effect of glomerular filtration rate in the association. Results The detection rate of CVD in Guizhou minority population was 3.16%, among which the detection rates of Dong, Miao and Buyi were 3.27%, 3.07% and 3.12%, respectively. The total detection rate of gallstones was 9.03%. Logistic regression analysis showed that after adjusting for all the variables (model 3), the detection rates of CVD in the total population [OR(95%CI): 1.633(1.269-2.102)], the Dong [OR(95%CI): 1.567(1.077-2.280)], and Miao [OR(95%CI): 1.679(1.055-2.673)], gallstones were positively associated with CVD. No association between gallstones and CVD was found in the Buyi population. Subgroup analysis showed that Dong patients with gallstones < 60 years old were positively correlated with CVD [OR(95%CI): 1.825(1.022-3.258)], gallstone patients without hyperlipidemia [OR(95%CI): 2.151(1.352-3.422)], gallstone patients without hypertension [OR(95%CI): 1.612(1.013-2.565)] were positively correlated with CVD. Miao ≥ 60 years old [OR(95%CI): 1.878(1.038-3.397)], male [OR(95%CI): 1.546(1.212-5.586)], BMI ≥ 24 [OR(95%CI): 1.972(1.160-3.354)], gallstone patients with hypertension [OR(95%CI): 2.264(1.297 - 5.429)] were positively correlated with CVD. Mediation analysis revealed that the glomerular filtration rate accounted for 16.96%, 12.08%, 17.43%, and 14.52% of the mediating effect between gallstones and CVD in the total population, Dong, Miao, and Buyi people, respectively. Conclusion Gallstones are positively correlated with CVD in the Dong and Miao populations in Guizhou Province, especially in the overweight and hypertension population of the Miao nationality. There is no association between gallstones and CVD in the Buyi population. Glomerular filtration rate has a partial mediating effect between gallstones and CVD. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to investigate the emotion regulation effect of Baduanjin Qigong on college students. Methods: The late positive potential (LPP) components were recorded while performing emotional pictures from 12 college students with Baduanjin Qigong experience and 12 with no experience of any mind–body exercises. Results: Under positive emotional stimuli, greater LPP amplitudes were observed in the experimental group in the frontal, central, and temporal areas than in the control group. Under negative emotional stimuli, greater LPP amplitudes were found in the experimental group in the prefrontal area and smaller amplitudes in the occipital area than in the control group. Conclusion: The results reveal the emotion regulation effect on the event-related potential of Baduanjin Qigong to college students. The findings suggest that the regulatory effect of Baduanjin Qigong on emotional stimulation may be a possible reason for reducing the symptoms of depression and anxiety.

Single-mode operation with low-bending loss based on few-mode optical fiber is investigated. The fiber is designed with a group of ring modes in the cladding. The higher-order modes in the fiber can be eliminated by splicing with the single-mode optical fiber and bending the fiber to induce a strong coupling between the ring modes and the higher-order modes. Experimental results show that the bending losses of the LP01 mode can be lower than 0.001 dB/turn for a low-bending radius of 7.5 mm. The low-bending loss and the low splicing loss characteristics are also demonstrated. The proposed fiber can be bent multiple turns with a small bending radius which is preferable for fiber-to-the-home-related applications. [ABSTRACT FROM AUTHOR]
