Breast cancer is one of the cancers leading to most death cases among women and metastasis is the major cause of breast cancer mortality. In this study, Corylin, the flavonoid compound which is extracted and purified from Psoralea corylifolia L., the effect on breast cancer metastasis was investigated. Corylin showed inhibitory effect on migration and invasion abilities of breast cancer cells. ⋯ In conclusion, corylin suppresses metastasis of breast cancer cells via increasing miR-34c expression, which was dependent on p53. LINC00963 was a direct target of miR-34c and the target axis was necessary for corylin function. Therefore, corylin is a promising drug candidate and LINC00963 can be seen as a promising target in breast cancer treatment.

Coronavirus Disease (COVID-19) has caused global mental health impacts, and healthcare workers (HCWs) face an increased risk of exposure to the disease when compared to the general population. This study aimed to assess factors associated with mental health among Lebanese HCWs six months after the start of the COVID-19 pandemic. A cross-sectional study was conducted among HCWs at a tertiary hospital, in Lebanon between June and July 2020. ⋯ HCWs who reported signs of depression were less likely to altruistically accept the risks of caring for COVID-19 patients, compared to those who did not (57% vs 74%; p = 0.03). This study aimed to detect factors associated with mental health among Lebanese HCWs during the COVID-19 pandemic. Findings suggested that altruistic acceptance of COVID-19 risks is higher among HCWs with positive exposure history to COVID-19 and those with less depressive symptomatology.

The multiplication of social networking sites has led to increased frequency of use among young adults. While the association with mental wellbeing is still controversial, high levels of social media use were correlated with problematic behaviours, low self-esteem and depressive symptoms. 'Social Media Detoxification' (Detox) is the term used to describe voluntary attempts at reducing or stopping social media use to improve wellbeing. ⋯ These preliminary findings show that 'social media detoxification' is a phenomenon understood and used by university students to moderate their social media use. Wide variability in its application and effects is noted in our sample.

Zika virus (ZIKV) is a serious public health concern that may lead to neurological disorders in affected individuals. The virus can be transmitted from an infected mother to her fetus, via mosquitoes, or sexually. ZIKV infections are associated with increased risk for Guillain-Barré syndrome (GBS) and congenital microcephaly in newborns infected prenatally. ⋯ In particular, we determined that hsa-mir-431-5p, hsa-mir-3687, hsa-mir-4655-5p, hsa-mir-6071, hsa-mir-762, hsa-mir-5787, and hsa-mir-6825-3p were significantly downregulated, ranging from -5711 to -660-fold whereas, has-mir-4315, hsa-mir-5681b, hsa-mir-6511a-3p, hsa-mir-1264, hsa-mir-4418, hsa-mir-4497, hsa-mir-4485-3p, hsa-mir-4715-3p, hsa-mir-4433-3p, hsa-mir-4708-3p, hsa-mir-1973 and hsa-mir-564 were upregulated, ranging from 20-0.8-fold. We carried out target gene alignment of these miRNAs with the ZIKV genome to predict the function of the differentially expressed miRNAs and their potential impact on ZIKV pathogenesis. These miRNAs might prove useful as novel diagnostic or therapeutic markers and targets for further research on ZIKV infection and neuronal injury resulting from ZIKV infectivity in developing fetal brain neurons.

This study examined leptin expression in cases of bladder cancer and its diagnostic and prognostic usefulness in bladder malignancies. A set of 128 urinary bladder cancer cases and 24 normal specimens of bladders were employed for an immunohistochemical investigation of leptin expression in tissue microarrays. ⋯ Furthermore, various important survival distributions were detected with leptin expression in the malignant urothelium (P < 0.03). These pilot results suggest that leptin might be a valid marker for predicting the stage and bad prognoses in bladder carcinoma.
