Two spurge species, Euphorbia resinifera O. Berg and Euphorbia officinarum subsp. echinus (Hook.f. & Coss.) Vindt inhibit colon cancer.

BACKGROUND: Colon cancer, a prominent contributor to global cancer-related deaths, prompts the need for innovative treatment strategies. Euphorbia resinifera O. Berg (E. resinifera) and Euphorbia officinarum subsp. echinus Hook. f. & Coss Vindt (E. echinus) and their bee-derived products have been integral to traditional Moroccan medicine due to their potential health benefits. These plants have historical use in addressing various health issues, including cancer. However, their effects against colon cancer remain unclear, and the specific mechanisms underlying their anti-cancer effects lack comprehensive investigation. METHODS: The study aimed to assess the potential anti-cancer effects of Euphorbia extract on colon cancer cell lines (DLD-1) through various techniques. The apoptosis, migration, and proliferation of DLD-1 cells were measured in DLD-1 cells. In addition, we conducted High-Performance Liquid Chromatography (HPLC) analysis to identify the profile of phenolic compounds present in the studied extracts. RESULTS: The extracts demonstrated inhibition of colon cancer cell migration. E. resinifera flower and E. echinus stem extracts show significant anti-migratory effects. Regarding anti-proliferative activity, E. resinifera flower extract hindered proliferation, whereas E. echinus flower extract exhibited dose-dependent inhibition. Apoptosis assays revealed E. resinifera flower extract inducing early-stage apoptosis and E. echinus flower extract promoting late-stage apoptosis. While apoptotic protein expression indicated, E. resinifera stem and propolis extracts had minimal impact on apoptosis. CONCLUSION: The findings provide evidence supporting the beneficial effects of E resinifera and E. echinus extracts on colon cancer and exerting anti-cancer properties.

Small Dense LDL Level and LDL/HDL Distribution in Acute Coronary Syndrome Patients.

This study aimed to determine the size and distribution of LDL and HDL particles in North African acute coronary syndrome (ACS) patients and to compare the level of small dense LDL (sdLDL) to other markers used in cardiovascular risk prediction. METHODS: A total of 205 ACS patients and 100 healthy control subjects were enrolled. LDL particle size and LDL and HDL subclass distributions were measured using Quantimetric Lipoprint® linear polyacrylamide gel electrophoresis. Lipid ratios (total cholesterol, LDL cholesterol, non-HDL cholesterol, and HDL cholesterol) were determined to calculate the atherogenic index of plasma (AIP), the atherogenic coefficient (AC), Castelli's Risk-I (CR-I), and Castelli's Risk-II (CR-II). Receiver operating characteristic (ROC) curve analyses and area under the curve (AUC) were used to assess the predictive value of sdLDL as a marker for cardiovascular disease. RESULTS: The ACS patients, compared to the healthy control subjects, displayed an alteration of LDL particle distribution, with a significant increase in sdLDL serum concentrations (0.303 ± 0.478 mmol/L vs. 0.0225 ± 0.043 mmol/L, respectively, p < 0.001). The sdLDL levels had a high discrimination accuracy [AUC = 0.847 ± 0.0353 (95% CI 0.778 to 0.916, p < 0.0001)]. The best predictive cutoff value of ACS determined with the maximum Youden index (J) [(sensitivity + specificity) - 1 = 0.60] was 0.038 mmol/L. A Spearman correlation analysis showed that sdLDL levels were moderately but significantly and positively correlated with AC and CR-I (r = 0.37, p < 0.001) and weakly but significantly correlated with PAI and CR-II; r = 0.32 (p < 0.001) and r = 0.30 (p < 0.008), respectively. The subclass distribution of HDL particles from ACS patients was also altered, with a decrease in large HDL particles and an increase in small HDL particles compared to HDL from healthy control subjects. CONCLUSION: Due to their high atherogenicity, sdLDL levels could be used as a valuable marker for the prediction cardiovascular events.

Eco-friendly degradation of reactive red 195, reactive blue 214, and reactive yellow 145 by Klebsiella pneumoniae MW815592 isolated from textile waste.

The water is used in many textile manufacturing steps beyond cleaning. The quantity and the significant chemical load of the effluents generated constitute the primary challenge of the textile industry. In order to discover new sustainable methods to overcome this problem, the aim of this research was to study the potential for degradation of Reactive Blue 214, Reactive Red 195, and Reactive Yellow 145 using a dye degrading bacterium. Sequencing analysis reveals it to be Klebsiella pneumoniae MW815592. This strain completely decolorized artificial effluent (200 mg/L) after 42 h at pH 9 and 46 °C. The decolorization rate increased in the presence of glucose and yeast extract (2 g). In addition, our finding revealed that the decolorization is due to biodegradation rather than adsorption on the bacterial surface.

Euphorbia species latex: A comprehensive review on phytochemistry and biological activities.

The genus Euphorbia includes about 2,000 species commonly widespread in both temperate and tropical zones that contain poisonous milky juice fluid or latex. Many species have been used in traditional and complementary medicine for the treatment of various health issues such as dropsy, paralysis, deafness, wounds, warts on the skin, and amaurosis. The medicinal applications of these species have been attributed to the presence of various compounds, and most studies on Euphorbia species have focused on their latex. In this review, we summarize the current state of knowledge on chemical composition and biological activities of the latex from various species of the genus Euphorbia. Our aim was to explore the applications of latex extracts in the medical field and to evaluate their ethnopharmacological potential. The databases employed for data collection, are obtained through Web of Science, PubMed, Google Scholar, Science Direct and Scopus, from 1983 to 2022. The bibliographic data indicate that terpenoids are the most common secondary metabolites in the latex. Furthermore, the latex has interesting biological properties and pharmacological functions, including antibacterial, antioxidant, free radical scavenger, cytotoxic, tumor, anti-inflammatory, healing, hemostatic, anti-angiogenic, insecticidal, genotoxic, and mutagenic activities. However, the role of other components in the latex, such as phenolic compounds, alkaloids, saponins, and flavonoids, remains unknown, which limits the application of the latex. Future studies are required to optimize the therapeutic use of latex extracts.

Genus Ziziphus: A comprehensive review on ethnopharmacological, phytochemical and pharmacological properties.

ETHNOPHARMACOLOGICAL RELEVANCE: The genus Ziziphus (Rhamnaceae) contains 58 accepted species that are extensively used by local people and medicinal practitioners in arid and semi-arid regions for the treatment of diarrhoea, dysentery, cholera, diabetic, hypertension, inflammation, intestinal spasm, liver, malaria and other diseases. Aims of this review: This review article documents and critically assesses, for the first time; up to date categorized information about botanical traits, distribution, traditional uses, phytochemistry, pharmacological and toxicological effects of Ziziphus species. METHODS: Information was collected systematically from electronic scientific databases including Google Scholar, Science Direct, PubMed, Web of Science, ACS Publications, Elsevier, SciFinder, Wiley Online Library and CNKI, as well as other literature sources (e.g., books). KEY FINDINGS: The phytochemical investigations of plants of this genus have led to the identification of about 431 chemical constituents. Cyclopeptide alkaloids and flavonoids are the predominant groups. The crude extracts and isolated compounds exhibit a wide range of in vitro and in vivo pharmacologic effects, including antimicrobial, antitumour, antidiabetic, antidiarrhoeal, anti-inflammatory, antipyretic, antioxidant and hepatoprotective activities. Toxicity studies indicate that Ziziphus species seems to be non-toxic at typical therapeutic doses. CONCLUSION: Phytochemical and pharmacological studies have demonstrated that Ziziphus species are important medicinal herbs with prominent bioactivities. The focus so far has only been on ten species; however, plants of this genus can potentially yield a wide range of other products with different properties. Meticulous studies on pharmaceutical standardisation, mode of action of the active constituents and toxicity of Ziziphus species are needed to meet the growing demands of the pharmaceutical industry and to exploit their preventive and therapeutic potential fully.

Improved Method for DNA Extraction and Purification from Tetrahymena pyriformis.

Tetrahymena pyriformis (protozoa) is intensely investigated as a model organism, offering numerous advantages in comprehensive and multidisciplinary studies using morphologic or molecular methods. Since DNA extraction is a vital step of any molecular experiment, here a new mixed surfactant (Sodium dodecyl sulfate (SDS) 20%/Triton X-100) was adopted for effective DNA extraction from Tetrahymena pyriformis under an easy, fast protocol. The efficiency of this technique was then compared with three widely-used alternative techniques, namely the Chelex 100 matrix, Ammonium pyrrolidine dithiocarbamate (APD) complex and SDS-chloroform methods. DNA extraction was analyzed by pulsed-field gel electrophoresis, spectral measurement, fluorometry (Qubit), restriction enzyme digestion, and polymerase chain reaction. Data analysis revealed that the quantity and quality of the recovered DNA varied depending on the applied DNA extraction method. The new method (SDS 20%/Triton X-100) was the most efficient for extracting DNA from Tetrahymena pyriformis with high integrity and purity, affordable cost, less time, and suitability for molecular applications.

Purification and partial characterization of camel (Camelus Dromedarius) ceruloplasmin.

Adult and young camel ceruloplasmin (Cp) were isolated and purified using the single-step chromatography on amino ethyl-activated sepharose. There are no differences between the adult and the young camel protein. The molecular mass of the protein, as estimated by SDS-PAGE (denaturant conditions), was approximately 130000 Da. The electrophoretic mobility of camel Cp is slightly higher as compared to human and sheep protein suggesting that the camel Cp is homogeneous, compact and more acid. The copper content was estimated to be 5.8+/-0.3 atoms per molecule. The spectroscopic feature includes an absorption maximum at 610 nm, which could be attributed to type 1 copper. The EPR spectrum was completely devoid of any typical signal of the type 2 copper. The kinetic parameters of the adult camel Cp for the specific activity as p-phenylendiamine oxidase were determined as K(m)=0.42 mM and V(max)=0.93 microM NADH/mn/mg Cp. The optimum pH for the activity was 5.7.
