Additionally, at comparable effective doses to cancer, bacopasaponins showed much less toxicity in normal human peripheral blood lymphocytes (≥ 85% cell survival). Overall, the findings project bacopasaponin F, a natural constituent of Bacopa monniera, as an efficient and safer alternative for breast cancer therapeutics.One of the most recent of tumor molecular characterization approaches is the microRNA (miR) expression profile. No single marker is sufficiently accurate for clinical use. Numerous biomarkers panels were created for three main purposes tumor subtype, classification and, early detection, and prediction of tumor responses to treatment and prognosis of patients. miR-21-5p and miR-126-3p have received special attention because of their relationship with many cancer sites such as lung cancer, colorectal cancer, and renal cell carcinoma. We aimed to study their diagnostic and prognostic utility in lung cancer patients. Serum carcinoembryonic antigen (CEA) level was measured using an enzyme-linked immunosorbent assay (ELISA) technique. The expression levels of miR-21-5p and miR-126-3p were determined by real-time PCR in 60 non small cell lung cancer (NSCLC) patients and 40 healthy controls to detect diagnostic utility. Moreover, it was correlated with all disease clinicopathological characters and patient survival. Higher miR-21-5p and lower miR-126-3p levels were found in lung cancer patients than in controls. The sensitivity of CEA and miR-21-5p and miR-126-3p were 78.3, 96.7, and 90% at cutoff points 7.5, 2.35, and 2.175, respectively to distinguish NSCLC patients from controls. On combining both miR-21-5p and miR-126-3p, an improvement of sensitivity to 97% was noted. For patients, miR-21-5P increased significantly with metastatic stage and the highest grade (GIII). There was significantly longer overall survival (OS) among patients with early stages, lower grades GI&II, low miR-21-5p, and high miR-126-3p. miR-126-3p and presence of metastasis, the last two factors were the independent factors affecting OS with a hazard ratio of 0.26 (95% CI 0.06-1.09) and 3.64 (95% CI 1.22-16.5), respectively. Circulating miR-21-5p and miR-126-3p may play a significant role in diagnosis and prognosis in NSCLC patients.Sugarcane mosaic virus (SCMV) is a serious disease of monocotyledonous plants, including sugarcane, causing deterioration in both growth and productivity. RNA interference (RNAi) inhibits gene expression through RNA-mediated sequence-specific interactions and is considered an effective approach to control viral infection in plants. In this study, the SCMVCp gene encoding the coat protein (CP) was inserted into the pGreen-0179 plasmid in both sense and antisense orientations. Cauliflower mosaic virus (CaMV) and Zea mays ubiquitin (Ubi) promoters were selected to drive the transcription of the intron-hairpin constructs, called HpSCMVCp-CaMV and HpSCMVCp-Ubi, respectively. Transgenic sugarcane expressing these constructs was generated through Agrobacterium-mediated transformation. This transformation method produced a high percentage of transgenic plants for both HpSCMVCp-CaMV and HpSCMVCp-Ubi, as confirmed by PCR analysis. Southern blotting revealed a single stable insertion of the DNA target in the genome of transgenic sugarcane lines. After artificial virus infection, lines that developed mosaic symptoms were classified as susceptible, whereas those that remained green without symptoms were classified as resistant at 42 days post-inoculation. Immunoblotting revealed CP expression at 37 kDa in susceptible and non-transgenic sugarcane, but not in resistant lines. RT-PCR analysis confirmed viral Cp and Nib gene expression in susceptible lines and their absence in resistant lines. Interestingly, upon comparison of effectivity, CaMV and Ubi promoter-driven gene expression resulted in 57.69% and 82.35% resistant sugarcane lines, respectively. Thus, we concluded that RNAi is effective for inducing resistance against SCMV and that the Ubi promoter is an effective promoter for producing transgenic sugarcane.The renin-angiotensin-aldosterone system and its metabolites play an important role in homeostasis of body, especially the cardiovascular system. In this study, we discuss the imbalance of multiple systems during the infection and the importance of therapeutic choice, dosing, and laboratory monitoring of cardiac and anti-coagulant therapies in COVID-19 patients. this website The crosstalk between angiotensin, kinin-kallikrein system, as well as inflammatory and coagulation systems plays an essential role in COVID-19. Cardiac complications and coagulopathies imply the crosstalks between the mentioned systems. We believe that the blockage of bradykinin can be a good option in the management of COVID-19 and CVD in patients and that supportive treatment of respiratory and cardiologic complications is needed in COVID-19 patients. Ninety-one percent of COVID-19 patients who were admitted to hospital with a prolonged aPTT were positive for lupus anticoagulant, which increases the risk of thrombosis and prolonged aPTT. Therefore, the question that is posed at this juncture is whether it is safe to use the prophylactic dose of heparin particularly in those with elevated D-dimer levels. It should be noted that timing is of high importance in anti-coagulant therapy; therefore, we should consider the level of D-dimer, fibrinogen, drug-drug interactions, and risk factors during thromboprophylaxis administration. Fibrinogen is an independent predictor of resistance to heparin and should be considered before thromboprophylaxis. Alteplase and Futhan might be a good choice to assess the condition of heparin resistance. Finally, the treatment option, dosing, and laboratory monitoring of anticoagulant therapy are critical decisions in COVID-19 patients.

Glaucoma is a progressive disease of the optic nerve that has several underlying causes, but in most cases, the cause is unknown. Given the importance of the role of nitric oxide in the occurrence of ocular nerve damage and the effect of eNOS gene polymorphic sites on protein function, to better understand the mechanism of formation of POAG, the relationship between polymorphisms rs2070744 and rs1799983 eNOS gene with POAG risk was investigated in this study using meta-analysis.

In this study, systematic review and meta-analysis of study data related to the study of polymorphisms rs2070744 and rs1799983 eNOS gene in patients with POAG using the keywords eNOS, NOS3, Gluuc8898, POAG, primary open-angle glaucoma. It was extracted from SID, MagIran, IranMedex, IranDoc, ScienceDirect, Embase, Scopus, PubMed, Web of Science, and Google Scholar search engines without a time limit until May 2020. To perform the analysis of qualified studies, the model of random effects was used and the inconsistency of studies with the I

index was investigated.
