Anticancer Potential of Furanocoumarins: Mechanistic and Therapeutic Aspects

Cancer is one of the most extreme medical conditions in both developing and developed countries around the world, causing millions of deaths each year. Chemotherapy and/or radiotherapy are key for treatment approaches, but both have numerous adverse health effects. Furthermore, the resistance of cancerous cells to anticancer medication leads to treatment failure. The rising burden of cancer overall requires novel efficacious treatment modalities. Natural medications offer feasible alternative options against malignancy in contrast to western medication. Furanocoumarins' defensive and restorative impacts have been observed in leukemia, glioma, breast, lung, renal, liver, colon, cervical, ovarian, and prostate malignancies. Experimental findings have shown that furanocoumarins activate multiple signaling pathways, leading to apoptosis, autophagy, antioxidant, antimetastatic, and cell cycle arrest in malignant cells. Additionally, furanocoumarins have been shown to have chemo preventive and chemotherapeutic synergistic potential when used in combination with other anticancer drugs. Here, we address different pathways which are activated by furanocoumarins and their therapeutic efficacy in various tumors. Ideally, this review will trigger interest in furanocoumarins and their potential efficacy and safety as a cancer lessening agents

Co2 exchange and biomass development of the herbaceous vegetation in the portuguese montado ecosystem during spring

Montado are spatially heterogeneous ecosystems that are economically important for the production of cork and herbaceous biomass that provide fodder for animals. Understanding of how trees and the herbaceous layer interact to determine pasture yield and the overall CO2 exchange of the herbaceous layer is crucial. Portable chamberswere used to study CO2 exchange by the herbaceous layer component of the montado ecosystem in southern Portugal. Biomass, Net herbaceous layer CO2 exchange (NEE) and respiration (Reco) were measured in the open and understory locations between March and May, during the active growing period. Parameter fits on the NEE data were performed using empirical hyperbolic light response model, while ecosystem respiration (Reco) data were fitted with a two-parameter exponential model. Annual green biomass productions were 405.8 9.0 and 250.6 6.3 g m 2 in the open and the understory, respectively. The respective maximum NEE during the day were 24.0 2.9 and 9.6 2.2 mmol m 2 s 1 while maximum Reco were 20.6 2.2 and 10.0 1.6 mmol m 2 s 1, occurring in April. Photosynthetic photon flux density (PPFD) explained more that 70% of variations in daytime NEE while soil temperature at 10 cm depth (Tsoil) explained >50% of the variations in Reco under non-limiting soil moisture conditions. Both the herbaceous layer communities shared similar plant functional types and no significant difference in nutrient nitrogen (N) occurred between them. The two herbaceous layer components shared similar physiological characteristics and differences that arose in their CO2 uptake capacities and green biomass production were the result of microclimatic differences created by tree shadin

Quantification of three macrolide antibiotics in pharmaceutical lots by HPLC: Development, validation and application to a simultaneous separation

A new validated high performance liquid chromatographic (HPLC) method with rapid analysis time and high efficiency, for the analysis of erythromycin, azithromycin and spiramycin, under isocratic conditions with ODB RP18 as a stationary phase is described. Using an eluent composed of acetonitrile –2-methyl-2-propanol –hydrogenphosphate buffer, pH 6.5, with 1.5% triethylamine (33:7: up to 100, v/v/v), delivered at a flow-rate of 1.0 mL min-1. Ultra Violet (UV) detection is performed at 210 nm. The selectivity is satisfactory enough and no problematic interfering peaks are observed. The procedure is quantitatively characterized and repeatability, linearity, detection and quantification limits are very satisfactory. The method is applied successfully for the assay of the studied drugs in pharmaceutical dosage forms as tablets and powder for oral suspension. Recovery experiments revealed recovery of 97.13–100.28%

Comparison of Some Cardiovascular Risk Factors between Active and Sedentary Elderly Men

Background: One of the major problems threatening the world’s people are cardiovascular diseases, accounting for 30% of the deaths. The factors exposing people to this danger are called risk factors. Objective: This study aimed to compare the cardiovascular risk factors and C-reactive protein between active and sedentary elderly men. Methods: The study was a descriptive comparison of two groups that were conducted in Rasht city in 2015. The subjects of this study consist of 30 active elderly men and 30 sedentary elderly men who were selected non-randomly and purposefully. Inclusion criteria of research for active subjects were have regular physical activity at least six months and don’t use cigarette and pills that affect profile lipids and inclusion criteria for sedentary subjects were don’t have regular physical activity and also don’t use cigarette and pills that affect profile lipids. The measured cardiovascular risk factors of subjects include fasting blood sugar (FBS), triglyceride (TG), total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), very low-density lipoprotein (VLDL), glycated haemoglobinA1c (HbA1c), and C-reactive protein (CRP). The statistical methods used for data analysis are Kolmogorov-Smirnov test, t-student, and U Mann-Whitney with significance level less than 0.05. Findings: The t-student exam shows that cardiovascular risk factors, including FBS, TG, TC, HDL, VLDL, HbA1c, and CRP, in active elderly men are lower than sedentary elderly men. This difference is also statistically significant (P≤0/01). Conclusion: The study showed that cardiovascular risk factors in active elderly men are less than sedentary ones. However, 80% of active elderly men had still at least one or several cardiovascular risk factors. Keywords: Elderly, Cardiovascular Risk Factors, Active, Sedentar

A study on the chemical characteristics changes throughout the manufacture and ripening of Lighvan cheese

Lighvan cheese is one of the traditional cheeses which have the most high quantity of use in Iran. It is produced in South East of Tabriz in North West of Iran. The raw milk of ewe together with 20% -30% of goat's milk, without yeast, are used for its production. Its taste is mild salty and its scent is pleasant. The purpose of this study was to investigate the chemical indexes changes including salt percentage, the degree of acidity, pH, dry mater, ashes, and protein during the production and ripening. For this purpose, after coordinating with 10 local cheese producers, one batch from each producer and from each batch 20 tins, weighing 1 kg, which in total was 200 newly packaged cheese were purchased randomly. The tins were kept in special caves for 30 days in the region and then 60 days in refrigerator. In each batch sample of the raw milk, clot after rising and before salting, the cheese during the package time in tin and the cheese sample on 15th, 30th, 60th, and 90th days of ripining was analyzed chemically. The results of the study from the initial days of production to the end of the ripening period indicated the following changes: the rate of fat from 6.8 ± 0.25 in milk to 24.55±0.95 in samples, pH from 5.94± 0.06 in milk to 4.4±0.11 in samples, acidity from 39.4 ± 5.99 D° in milk to 119.4±5.38 in samples, rate of ash from 1.77±0.23 in milk to 8.09±2.32 in samples, the percentage of dry mater from 16.52±0.74 in milk to 43.57±1.34 in samples, and finally the percentage of protein from 4.45±1/12 in milk to 14.2±1.4 in samples. This result suggests that Lighvan cheese has unique characteristics in terms of its alteration procedure and chemical characteristics and based on the standard criterion in Iran, 2344-1, it is white cheese ripened brine in terms of chemical characteristics and fatty cheese in terms of the percentage of fat
