Only 132 patients matched the inclusion criteria, while other cases were excluded because of other diseases associated with cancer. The standardized problem list (PL) and Hospital Anxiety and Depression Scale (HADS) were implemented in comparison with DT. Then, the cut-off score of DT was performed to identify clinically significant differences.The analysis of the receiver operating characteristic (ROC) curve revealed that a DT cut-off score of 4 displayed 0.76 under the ROC curve. Sensitivity showed 0.86 sensitivity for cut-off score 4 and a specificity of 0.56 relative to the HADS cut-off score (≥15). DT scores were found independent of medical variables such as cancer type and stage, recurrence, or metastasis. Clinical ECOG-SP showed a significant association with the DT cut-off score (P ≤ 0.05). Regarding PL, patients with scores above DT cut-off were suffering 21 of 40 problems in all categories.

A cross-sectional study was conducted among HCWs at a tertiary hospital, in Lebanon between June and July 2020. The survey included data on demographics, exposure to COVID-19, preparedness to COVID-19 outbreak, risk perceptions of COVID-19, and mental health dimensions.

Corylin showed inhibitory effect on migration and invasion abilities of breast cancer cells. Meanwhile, the epithelial-mesenchymal transition was also regulated by corylin. The long non-coding RNA LINC00963 was found to have a significantly high expression level in breast cancer while it can be down-regulated by corylin. In addition, both wound-healing assay and transwell assay showed that LINC00963 induced breast cancer cells metastasis. MiR-34c was increased by corylin treatment depending on p53, and it was firstly identified that the LINC00963 was a direct target of miR-34c. Corylin was verified here that it prohibited MCF-7 migration and invasion depending on miR-34c/LINC00963 target. In conclusion, corylin suppresses metastasis of breast cancer cells via increasing miR-34c expression, which was dependent on p53.

The activity of this plant is regarded to the bio-production of secondary metabolites like alkaloids, phenols, flavonoids, and most unique group of compounds, namely, annonaceous acetogenins. Whilst this plant is gaining popularity as an anticancer treating plant, this study was undertaken to verify the plausible anticancer effect of leaf methanol extracts of &lt;i&gt;A. muricata&lt;/i&gt; (LEAM). Acute toxicity study was carried to obtain safe dose in mice models using haematological, biochemical, and histological evaluations in Swiss albino mice. &lt;i&gt;In-vitro&lt;/i&gt; cytotoxicity towards Dalton's Lymphoma Ascites (DLA) and Ehrlich Ascites Carcinoma (EAC) cell lines were determined by trypan blue exclusion method. &lt;i&gt;In-vivo&lt;/i&gt; antitumour activity of LEAM (100, 200, and 500mg/kg b.wt.) was evaluated using DLA induced solid carcinoma and EAC induced ascites carcinoma models and its comparison with standard drug Cisplatin. Acute toxicity studies did not exhibit significant variations in treated mice suggesting diminutive side effects of LEAM. Statistical analysis revealed the IC&lt;sub&gt;50&lt;/sub&gt; values for DLA and EAC cell lines as 85.56 ± 5.28 and 68.07 ± 7.39 µg/mL, respectively, indicating better cytotoxic activity against EAC than DLA cells. LEAM decreased the tumour burden in dose-dependent manner. In comparison, with different concentrations tested, treatment with LEAM (200 mg/kg b.wt. and 500 mg/kg b.wt.) significantly reduced the solid tumour volume development by 58.11% and 65.70%, respectively. While lifespan was prolonged up to 51.43% in 500 mg/kg b.wt. LEAM treated ascites tumour-induced mice. This study thus indicates that LEAM possesses potent cytotoxic and antineoplastic activity and calls for more methodical safety assessments and other end-points of anti-tumourigenesis. &lt;b&gt;Abbreviations&lt;/b&gt;: &lt;b&gt;LEAM&lt;/b&gt;: Leaf methanol extract of &lt;i&gt;Annona&lt;/i&gt; muricata; &lt;b&gt;DLA&lt;/b&gt;: Dalton's Lymphoma Ascites; &lt;b&gt;EAC&lt;/b&gt;: Ehrlich Ascites Carcinoma; &lt;b&gt;IC&lt;sub&gt;50&lt;/sub&gt;&lt;/b&gt; : Half maximal inhibitory concentration; &lt;b&gt;CPCSEA&lt;/b&gt;: Committee for the Purpose of Control Supervision of Experiments on Animal; &lt;b&gt;IAEC&lt;/b&gt;: Institutional Animal Ethics Committee; &lt;b&gt;ARRIVE&lt;/b&gt;: Animal Research: Reporting &lt;i&gt;In-vivo&lt;/i&gt; Experiments; &lt;b&gt;DMSO&lt;/b&gt;: Dimethyl sulphoxide; &lt;b&gt;LD&lt;sub&gt;50&lt;/sub&gt;&lt;/b&gt; : Lethal Dose, 50%; &lt;b&gt;SD&lt;/b&gt;: Standard Deviation; &lt;b&gt;Hb&lt;/b&gt;: Haemoglobin; &lt;b&gt;RBC&lt;/b&gt;: Red blood cells; &lt;b&gt;WBC&lt;/b&gt;: White blood cells; &lt;b&gt;HCT&lt;/b&gt;: Hematocrit; &lt;b&gt;MCV&lt;/b&gt;: Mean cell volume; &lt;b&gt;MCH&lt;/b&gt;: Mean cell haemoglobin; &lt;b&gt;MCHC&lt;/b&gt;: Mean cell haemoglobin concentration; &lt;b&gt;SALP&lt;/b&gt;: Serum alkaline phosphatase; &lt;b&gt;SGPT&lt;/b&gt;: Serum glutamic pyruvic transaminase; &lt;b&gt;SGOT&lt;/b&gt;: Serum glutamic oxaloacetic transaminase; &lt;b&gt;ATP&lt;/b&gt;: Adenosine triphosphate; &lt;b&gt;EGFR&lt;/b","PeriodicalId":49910,"journal":{"name":"Libyan Journal of Medicine","volume":"16 1","pages":"1846862"},"PeriodicalIF":2.4,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/19932820.2020.1846862","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38765694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
