Decorin (DCN) regulates a vast array of cellular processes including proliferation, migration, apoptosis, and autophagy, and its aberrant expression has been associated with poor extravillous trophoblasts (EVT) invasion of the uterus, which underlies the occurrence of preeclampsia (PE) and intrauterine growth restriction (IUGR). In this study, we aim to elucidate the molecular mechanism of how the DCN regulates the cell functions through the use of trophoblast cell line, HTR-8. Using a series of cell function assays, including CCK8, RTCA, transwell, scratch-wound assay, and Annexin V staining, we found that DCN suppressed proliferation and invasion, while promoted autophagy and apoptosis of HTR-8 in a dose-dependent manner. Transient stimulation of DCN have increased the activity of c-Met and its downstream effectors - Akt, FAK and m-TOR. However, a prolonged exposure to DCN have significantly downregulated the expression of c-Met, leading to suppression of its downstream effectors. Lentivirus that overexpressed c-Met targeting shRNA was used to knockdown c-Met expression and crizotinib was used to selectively inhibit the kinase activity of c-Met in HTR-8 cells. A combination of DCN and c-Met knockdown/inhibition have reduced the proliferation and invasion in HTR-8 cells; however, DCN-induced autophagy and apoptosis were not synergistically enhanced by c-Met inhibition. Cpd 20m clinical trial In conclusion, DCN promotes autophagy and apoptosis predominantly through downregulating c-Met/Akt/mTOR activity in human trophoblasts.During the past half century, evidence for inheritance of variable traits has accumulated from experiments in plants and animals and epidemiological studies in humans. Here, we summarize some of the reported cases of epigenetic inheritance and the proposed mechanisms involved in the transmission of non-genetic information between generations in plants, nematodes, flies and mammals. It has long been accepted that information is epigenetically inherited in plants. Although many questions regarding the underlying mechanisms remain to be answered, it is now evident that epigenetic mechanisms are also responsible for the transmission of phenotypes in animals. We highlight similarities and differences between models and species.BACKGROUND In December 2019, a few coronavirus disease (COVID-19) cases were first reported in Wuhan, Hubei, China. Soon after, increasing numbers of cases were detected in other parts of China, eventually leading to a disease outbreak in China. As this dreadful disease spreads rapidly, the mass media has been active in community education on COVID-19 by delivering health information about this novel coronavirus, such as its pathogenesis, spread, prevention, and containment. OBJECTIVE The aim of this study was to collect media reports on COVID-19 and investigate the patterns of media-directed health communications as well as the role of the media in this ongoing COVID-19 crisis in China. METHODS We adopted the WiseSearch database to extract related news articles about the coronavirus from major press media between January 1, 2020, and February 20, 2020. We then sorted and analyzed the data using Python software and Python package Jieba. We sought a suitable topic number with evidence of the coherence number. th communication. Comparing the number of articles for each day and the outbreak development, we noted that mass media news reports in China lagged behind the development of COVID-19. The major themes accounted for around half the content and tended to focus on the larger society rather than on individuals. The COVID-19 crisis has become a worldwide issue, and society has become concerned about donations and support as well as mental health among others. We recommend that future work addresses the mass media's actual impact on readers during the COVID-19 crisis through sentiment analysis of news data. ©Qian Liu, Zequan Zheng, Jiabin Zheng, Qiuyi Chen, Guan Liu, Sihan Chen, Bojia Chu, Hongyu Zhu, Babatunde Akinwunmi, Jian Huang, Casper J P Zhang, Wai-Kit Ming.

The world is reeling under the crisis caused by corona virus disease (COVID-19), print, electronic and social media are flooded with numerous advisories issued by governments and other national & international agencies. While all this is being done with best of intentions so as to contain the spread of this viral disease, this is causing a significant negative impact on mental health of people specially person of obsessive-compulsive disorder with fear of contamination and excessive washing of hands. INTRODUCTION Adrenal haemorrhage in the context of a pre-existing adrenal mass is a rare, underestimated and potentially fatal surgical emergency. It is a rare cause of acute abdominal pain. PRESENTATION OF CASES Data from 13 patients with adrenal haemorrhage in a pre-existing adrenal mass were prospectively collected during a 9 year period from a single institution. All patients underwent CT imaging which formed the basis of diagnosis and a complete endocrinological evaluation. Seven out of 13 patients underwent an elective surgical procedure and 2 patients underwent emergency laparotomy. Five out of 13 patients were diagnosed with metastatic disease. One patient was diagnosed with pheochromocytoma. DISCUSSION The likelihood of an undiagnosed pheochromocytoma renders emergency surgery extremely precarious. Complete patient evaluation includes testing for hormonally active adrenal tumors and malignancy. Emergency surgery is reserved for cases where conservative management fails. CONCLUSION Haemorrhage of an adrenal mass constitutes a diagnostic and therapeutic challenge. Most patients respond well to initial resuscitation efforts. When feasible, patients should undergo a complete hormonal and oncologic evaluation before surgical intervention is considered. Au@AuAg yolk-shell nanorods with tunable and uniform interior gap were synthesized through galvanic replacement reaction, where Au@Ag core-shell nanorods served as sacrificial templates and HAuCl4 solution served as reductant. The effects of HAuCl4, Ag shell thickness and aspect ratio (AR) of Au nanorods on the morphology of Au@AuAg yolk-shell nanorods had been investigated systemically. The results clearly indicated that AuAg alloy shell thickness of Au@AuAg yolk-shell nanorods could be increased from 3.6 to 10.0 nm by varying the amount of HAuCl4. Meanwhile, the shape of AuAg alloy shell could be tuned by changing the shape of Ag coating. With the increasing of Ag coating thickness, the interior gap could be finely tuned in the range from 2.6 to 8.1 nm. The uniformity of interior gap could be improved by increasing the AR of Au nanorods. All these tunable geometries can further affect the plasmonic spectral properties of Au@AuAg yolk-shell nanorods. Because of the appearance of interior gap, the longitudinal localized surface plasmon resonance (LSPR) peak of Au@AuAg yolk-shell nanorods was located between that of bare Au nanorods and Au@Ag core-shell nanorods without interior gap. The increase of outer AuAg shell thickness can weaken the coupling between the inner and outer surface of the AuAg shell and lead to the decrease of AR, so the transverse and longitudinal LSPR bands gather together. The decrease of Ag coating thickness can enhance the coupling between inner Au nanorod and outer AuAg shell, which results in the red shift of the longitudinal LSPR band. This paper provides a method for studying the plasmonic coupling between two metal surfaces with a metal layer or a dielectric layer, which is also a new approach for regulating the plasmonic spectral properties of bimetallic nanoparticles. The controllability of Au@AuAg yolk-shell nanorods in both the interior gap and outer alloy shells makes them have potential applications in biomedicine, catalysis, nanoreactors, and energy storage. Carbamazepine cocrystals with nicotinamide, saccharin and fumaric acid were synthesized and characterized by time-domain terahertz spectroscopy. Lattice vibrations of cocrystals with their individual constituents were investigated by means of the dispersion-corrected density functional theory with and without cell parameter constraints. The simulated THz spectra successfully reproduce the features of all the crystals in their experimental spectra. A better agreement between experimental and theoretical THz spectra is achieved when the cell parameter constraints are applied in geometry optimization. Some intensive modes of neat carbamazepine and cocrystals were discussed in terms of the motions of hydrogen bonds. The effect of lattice vibration on these cocrystallizations was further examined to gain insights into the thermodynamics. It is found that lattice vibration is favorable for all these cocrystal formations. Undergraduate nursing students face challenges that can result in stress leading to impaired performance, physical illness, high turnover and sickness absence (Kinman and Jones 2001). Students therefore require skills and knowledge to help them cope with the challenges of learning professional practice. This paper explores the concept of resilience, with an emphasis on how educational programmes can foster resilient practices among student nurses. Educators can facilitate resilience by incorporating resilience teaching and training that includes, the core concepts of resilience self-efficacy, reflective ability and self-confidence. Critical appraisal and synthesis of the literature resulted in the identification of three themes attributes, programmes and transition. The following five key learning and teaching methods were identified as supporting the development of resilience peer activities; reflective practice; directed study; problem based learning/enquiry based learning and experiential learning Having resilience and resilient qualities is an integral part of nursing, having a positive impact upon the health and well-being of the nurse as practitioner. Resilient qualities and behaviours can be developed through the facilitation of appropriate learning and teaching interventions. BACKGROUND COVID-19, the latest outbreak of infectious disease, has caused huge medical challenges to China and the entire globe. No unified diagnostic standard has been formulated. The initial diagnosis remains based on the positive of nucleic acid tests. However, early nucleic acid tests were identified to be negative in some patients, whereas the patients exhibited characteristic CT changes of lung, and positive test results appeared after repeated nucleic acid tests, having caused the failure to diagnose these patients early. The study aimed to delve into the relationships between initial nucleic acid testing and early lung CT changes in patients with COVID-19. METHOD In accordance with the latest COVID-19 diagnostic criteria, 69 patients diagnosed with COVID-19 treated in the infected V ward of Xiaogan Central Hospital from 2020/1/25 to 2020/2/6 were retrospectively analyzed. The consistency between the first COVID-19 nucleic acid test positive and lung CT changes was studied. In addition, the sensitivity and specificity of CT and initial nucleic acid were studied.
