Identification of key genes involved in secondary metabolite biosynthesis in Digitalis purpurea.

The medicinal plant Digitalis purpurea produces cardiac glycosides that are useful in the pharmaceutical industry. These bioactive compounds are in high demand due to ethnobotany's application to therapeutic procedures. Recent studies have investigated the role of integrative analysis of multi-omics data in understanding cellular metabolic status through systems metabolic engineering approach, as well as its application to genetically engineering metabolic pathways. In spite of numerous omics experiments, most molecular mechanisms involved in metabolic pathways biosynthesis in D. purpurea remain unclear. Using R Package Weighted Gene Co-expression Network Analysis, co-expression analysis was performed on the transcriptome and metabolome data. As a result of our study, we identified transcription factors, transcriptional regulators, protein kinases, transporters, non-coding RNAs, and hub genes that are involved in the production of secondary metabolites. Since jasmonates are involved in the biosynthesis of cardiac glycosides, the candidate genes for Scarecrow-Like Protein 14 (SCL14), Delta24-sterol reductase (DWF1), HYDRA1 (HYD1), and Jasmonate-ZIM domain3 (JAZ3) were validated under methyl jasmonate treatment (MeJA, 100 µM). Despite early induction of JAZ3, which affected downstream genes, it was dramatically suppressed after 48 hours. SCL14, which targets DWF1, and HYD1, which induces cholesterol and cardiac glycoside biosynthesis, were both promoted. The correlation between key genes and main metabolites and validation of expression patterns provide a unique insight into the biosynthesis mechanisms of cardiac glycosides in D. purpurea.

Mindfulness-based stress reduction (MBSR) effects on the worries of women with poly cystic ovary syndrome (PCOS).

INTRODUCTION: Polycystic ovary syndrome is one of the women's most common endocrine disorders that can cause anxiety, psychological distress, and reduced quality of life. Therefore, the present study aimed to determine the effect of mindfulness-based stress reduction counseling on the worries of women with polycystic ovary syndrome. MATERIALS AND METHODS: This quasi-experimental was implemented on 60 women with polycystic ovary syndrome, referring to health centers in Kerman, Iran, from April to September 2021. In the intervention group, MBSR was conducted in eight 90-minute sessions twice a week. A researcher-made questionnaire with 34 questions (with six domains including worries related to mental complications, interpersonal problems, non-pregnancy physical complications, pregnancy complications, sexual complications, and religious issues) on the worries of women with polycystic ovary syndrome was completed by the participants in two intervention and control groups as pre-and post-test and one month later. 22 SPSS statistical software was used for analysis. RESULTS: The mean score of worries in the intervention group (48.18 ± 5.18) compared to the control group (75.73 ± 8.08) was significantly reduced in total and all six domains immediately after the intervention (P < 0.0001). One month later also, the total mean score of worries and subtitles decreased significantly (P < 0.0001) in the intervention group (38.27 ± 3.58) in comparison with the control group (76.13 ± 7.52). CONCLUSION: Results showed that the method of reducing stress based on mindfulness had caused a significant reduction in worries in the intervention group. Therefore, this method can be used to improve the mental health of this group of patients in health centers.

Therapeutic effects of mesenchymal stem cells-conditioned medium derived from suspension cultivation or silymarin on liver failure mice.

BACKGROUND: Common treatments of liver disease failed to meet all the needs in this important medical field. It results in an urgent need for proper some new adjuvant therapies. Mesenchymal stem cells (MSCs) and their derivatives are promising tools in this regard. We aimed to compare the Silymarin, as traditional treatment with mesenchymal stem cell conditioned medium (MSC-CM), as a novel strategy, both with therapeutic potentialities in term of liver failure (LF) treatment. METHODS AND RESULTS: Mice models with liver failure were induced with CCl4 and were treated in the groups as follows: normal mice receiving DMEM-LG medium as control, LF-mice receiving DMEM-LG medium as sham, LF-mice receiving Silymarin as LF-SM, and LF-mice receiving MSC sphere CM as LF-MSC-CM. Biochemical, histopathological, molecular and protein level parameters were evaluated using blood and liver samples. Liver enzymes, MicroRNA-122 values as well as necrotic score were significantly lower in the LF-SM and LF-MSC-CM groups compared to sham. LF-SM showed significantly higher level of total antioxidant capacity and malondialdehyde than that of LF-MSC-CM groups. Sph-MSC-CM not only induced more down-regulated expression of fibrinogen-like protein 1 and receptor interacting protein kinases1 but also led to higher expression level of keratinocyte growth factor. LF-MSC-CM showed less mortality rate compared to other groups. CONCLUSIONS: Hepato-protective potentialities of Sph-MSC-CM are comparable to those of Silymarin. More inhibition of necroptosis/ necrosis and inflammation might result in rapid liver repair in case of MSC-CM administration.

Potential antidiabetic phytochemicals in plant roots: a review of in vivo studies.

BACKGROUND: Medicinal plants are used to treat various disorders, including diabetes, globally in a range of formulations. While attention has mainly been on the aerial plant parts, there are only a few review studies to date that are focused on the natural constituents present in the plant roots with health benefits. Thus, the present study was performed to review in vivo studies investigating the antidiabetic potential of the natural compounds in plant roots. METHODS: We sorted relevant data in 2001-2019 from scientific databases and search engines, including Web of Knowledge, PubMed, ScienceDirect, Medline, Reaxys, and Google Scholar. The class of phytochemicals, plant families, major compounds, active constituents, effective dosages, type of extracts, time of experiments, and type of diabetic induction were described. RESULTS: In our literature review, we found 104 plants with determined antidiabetic activity in their root extracts. The biosynthesis pathways and mechanism of actions of the most frequent class of compounds were also proposed. The results of this review indicated that flavonoids, phenolic compounds, alkaloids, and phytosteroids are the most abundant natural compounds in plant roots with antidiabetic activity. Phytochemicals in plant roots possess different mechanisms of action to control diabetes, including inhibition of α-amylase and α-glucosidase enzymes, oxidative stress reduction, secretion of insulin, improvement of diabetic retinopathy/nephropathy, slow the starch digestion, and contribution against hyperglycemia. CONCLUSION: This review concludes that plant roots are a promising source of bioactive compounds which can be explored to develop against diabetes and diabetes-related complications.

Investigating the effect of health literacy level on improving the quality of care during pregnancy in pregnant women covered by health centers.

BACKGROUND: Health literacy is the capacity to acquire, process, and understand basic information and services necessary for appropriate health decisions. Given the importance of health literacy in women, the aim of the present study was to determine the effect of health literacy level on improving the quality of care during pregnancy in pregnant women. MATERIALS AND METHODS: The present study was a cross-sectional analytical study. In this study, 130 women referred to Yazd health centers were examined. Health literacy questionnaires and a researcher-made checklist of the quality of pregnancy care were used to gather information. The researcher-made checklist of the quality of pregnancy care was in accordance with the standard protocol of the Ministry of Health and Medical Education, entitled Integrated Health Care for Pregnant Mothers, which was validated and reliable. SPSS statistical software version 19 and t-test and ANOVA statistical tests were used to analyze the data. RESULTS: According to the findings, the average score of health literacy in pregnant women was 74.09, which showed that the level of health literacy was in the marginal or border range. People with higher health literacy received significantly more prenatal counseling than other women and had a planned pregnancy (P = 0.04). CONCLUSION: The level of health literacy in pregnant women is unfavorable. Given that the high level of health literacy in women in society can lead to an increase in the quality of pregnancy care, so to increase health literacy in women, it is recommended that regular training in society by health-care providers be given more attention.

Vitamin D supplementation improves SIRT1, Irisin, and glucose indices in overweight or obese type 2 diabetic patients: a double-blind randomized placebo-controlled clinical trial.

BACKGROUND: Vitamin D (VD) may increase sirtuin 1 (SIRT1) and subsequently PPAR-γ coactivator 1α (PGC-1α) and irisin levels and these improvements may reduce insulin resistance (IR). The aim was to assess the effects of vitamin D supplementation on SIRT1, irisin, and IR in overweight/obese type 2 diabetes (T2D) patients. METHODS: Ninety T2D males and females were recruited as a clinical trial study (mean of age and body mass index (BMI) of intervention and placebo groups were 50.05 ± 10.17 and 50.36 ± 10.2 yrs. and 31.37 ± 3.4 and 30.43 ± 3.2 kg/m2, respectively). The inclusion criteria were T2D, VD deficient, BMI > 25 kg/m2, and serum HbA1c < 8.5%. The exclusion criteria were using vitamin and mineral supplements, having any acute disease, recent modifying dose or type of drugs. The supplementation was 50,000 IU/week VD or placebo for 8 weeks. The demographic characteristics, anthropometrics, dietary intakes and physical activity status, sun exposure status, fasting blood sugar (FBS) and insulin, glycosylated hemoglobin (HbA1c), irisin, SIRT1, 25-hydroxy D3 (25(OH)VD), homeostasis model assessment of insulin resistance (HOMA-IR), and quantitative insulin sensitivity check index (QUICKI) were determined. The significant P-value was ≤0.05. RESULTS: The increase of serum VD, SIRT1, and irisin in the intervention group was significant (p < 0.001). HbA1c was decreased significantly by 1%. The changes in the other glucose indices (FBS, insulin, and IR) were non-significant. CONCLUSIONS: VD supplementation may improve T2D by decreasing HbA1c and increasing SIRT1 and irisin in VD deficient T2D patients. Further trials are suggested.

Clinical trial for the management dysmenorrhea using selected spices.

BACKGROUND: Dysmenorrhea is the most common gynecologic complaint among adolescent and adult females. Some dysmenorrheic females do not respond to treatment with NSAIDs or oral contraceptives and exhibit contraindications to such medications. Therefore, alternative medication gained importance in management of dysmenorrhea. METHODS: A comparative clinical trial was conducted on thirty-one dysmenorrheic subjects, who were randomly assigned to three groups. The dosage was 1gr/day, 3gr/day and 3gr/day for Ginger, Dill seeds, and Cumin, respectively. The girls in respective group consumed the spice for three days during each cycle for three consecutive cycles. RESULTS: Dill seed was effective in reducing pain, followed by ginger wherein Cumin did not exhibit any effect. Cumin exhibited significant reduction in systemic responses like cold sweats, backache, fatigue and cramps. CONCLUSION: Dill seeds were more effective in reducing pain. It was obvious from our study that reducing symptoms is also important in the overall management of dysmenorrhea.
