Dyslipidemia is one of the most important risk factors of cardiovascular diseases (CVDs). Despite developments in pharmacological treatments for dyslipidemia there are several challenges. Recently some herbs highly considered to control dyslipidemia due to their low toxicity and high potency. In this study we investigated the effects of saffron petals on the lipid profile of dyslipidemia patients as well as several other biochemical blood factors. In this double blind, placebo controlled, clinical trial, we used systematic random sampling to divide 40 patients with at least two abnormalities in the following factors: (high-density lipoproteins (HDL) ≤40, low-density lipoproteins (LDL) ≥130, triglycerides (TG) ≥200, total cholesterol (Cho) ≥200), into 2 groups of 21 ones. At the end of the intervention period, serum lipid factors, alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), urea, creatinin (CR) and fasting blood sugar (FBS) were measured and statistically compared with their values just before the intervention. We found that the saffron petal pills markedly (P < 0.001) decreased the serum lipid levels of patients (TG, Cho and LDL) in the intervention group (113.81 ± 12.93, 56.52 ± 4.68 and 48.28 ± 3.70) as compared to the placebo group (18.42 ± 15.79, 4.57 ± 4.40 and 7.38 ± 3.54). Also, comparing the mean value of differences in two groups before and after the intervention showed significant reduction in TG (113.81 ± 26), Cho (56.53 ± 0.30) and LDL (48.28 ± 4.30) levels (P < 0.001). The saffron petal pills considerably reduced blood serum lipid profile and as well as urea and CR of dyslipidemia patients. So, this plant may be used as a potent phytomedicine for treatment and prevention of dyslipidemia and cardiovascular disorders. However, the results indicated that no statistical change was observed in the level of other biochemical blood factors such as ALT, AST, ALP and FBS.

Background: Lung cancer is one of the most common leading causes of mortality and morbidity worldwide. Despite recent advances in therapeutic approaches, common methods are not fully effective. Thus, researchers are looking for some novel complementary agents to improve the effectiveness of therapies. Emerging evidence has shown the antitumor activity of several natural components such as quinoa seed extracts in various types of cancer. Objectives: Hence, this study was conducted to evaluate the antiproliferation and anti-apoptotic activity of quinoa on the A549 lung cancer cell line. Methods: The cell viability of A549 cells treated with quinoa was detected using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The expression levels of BAX and BCL2 as apoptosis-related genes were assessed using real-time polymerase chain reaction (PCR). Finally, the statistical analysis was performed using GraphPad Prism version 7. Results: Our findings demonstrated that the cell viability decreased in a concentration and time-dependent manner. Also, treating A549 cells with doses of 1.60 and 1.92 mg/mL of quinoa seed extracts could increase BAX and decrease BCL2 expression levels (P < 0.05). However, the higher dose (1.92 mg/mL) was significantly effective. Conclusions: According to this study, quinoa seed extract could induce apoptosis in lung cancer cells (A549) throughout the increased ratio of BAX/BCL2. However, further investigations are required to confirm the results.

Background: Breast cancer is the most common female cancer that, despite recent progress, its existing therapies do not have sufficient efficiency, and scientists are trying to find complementary therapies. Medicinal plants, such as pomegranate (Punica granatum L.), attract a great deal of attention in this regard. Objectives: The present study aimed to assess the anticancer effects of pomegranate peel alcoholic extract (PPE) in the mouse cellular model (4T1) of breast cancer and investigate the related molecular mechanism of antiproliferative effects of the extract through the evaluation of the expression level of apoptosis genes (ie, BAX and BCL2). Methods: For the accomplishment of the study objectives, after the preparation of PPE, an evaluation of cellular cytotoxicity was carried out using the 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. According to the MTT assay, the cells were treated for 24 h with selective doses of the extract. Then, ribonucleic acid extraction, complementary deoxyribonucleic acid synthesis, and gene expression analysis of BAX and BCL2 using real-time polymerase chain reaction were performed in this study. Results: The results showed that PPE reduced cancer cell viability in a dose- and time-dependent manner. The molecular analysis indicated that observed cell death could be due to an increase in the BAX/BCL2 ratio. Conclusions: Overall, PPE can be proposed as a potential complementary therapy for breast cancer. However, further studies on animal models and clinical trials are needed to verify the clinical usage of such complementary drugs.

Context: Exosomes are nano-extracellular vesicles that carry biological molecules, including DNA, RNAs, and proteins, throughout the body. They can modulate intercellular communications and play key roles in signaling pathways and physiological responses. In the current review, we focused on exosomal miRNAs' roles in cancer development. Evidence Acquisition: This research was garnered from a large number of reports published in PubMed, ScienceDirect, Springer, Islamic Science Citation, and Magiran databases from 2000 to 2021. The keywords used were exosome, cancer, and microRNA. Results: The roles of exosomes in disease development and cancer have been investigated in several studies. It is revealed that exosome components such as microRNAs contribute to cancer-related processes, including cancer cell proliferation, metastasis, and angiogenesis. Conclusions: The findings showed that we could propose exosomes as cancer therapeutic targets and diagnostic biomarkers.
