Currently, there is increasing attention towards flavonoids and phenolic compounds of plant origin because of their association with decrease in the incidence of cardiovascular diseases and different types of cancer. The present study investigates the protective effect of Clerodendrum volubile (C. volubile) methanolic extracts against carbon tetrachloride (CCl4)-induced hepatotoxicity in rats. Control rats (group I) received olive oil (1 mL/kg, i.p.), group II received CCl4 in olive oil (1 ml/kg, i.p.) to induce hepatotoxicity, groups III, IV and V were pretreated with leaf extract of C...

Angiogenesis is the natural and physiologic process of growing blood vessels from pre-existing ones. Pathological angiogenesis occurs when the precise balance of all the molecular pathways that regulate angiogenesis is disrupted, and this process is a critical step in many diseases, including cancer. A limited number of antiangiogenic synthetic drugs have been developed. However, due to toxicity and side effects issues, the search for alternative to existing drugs is ongoing. In this sense, natural molecules obtained from plants or macrofungi, have demonstrated extraordinary potential in the treatment of angiogenesis-related pathologies, specially taking into consideration its absence or very low toxicity, when compared to synthetic drugs...

Polyphenols have an important protective role against a number of diseases, such as atherosclerosis, brain dysfunction, stroke, cardiovascular diseases, and cancer. Cardiovascular diseases are the number one cause of death worldwide: more people die annually from cardiovascular diseases than from any other cause. The most important behavioural risk factors of heart disease and stroke are unhealthy diet, physical inactivity, tobacco use, and excess alcohol intake. The dietary consumption of polyphenols has shown to be inversely associated with morbidity and mortality by cardio- and cerebrovascular diseases...

BACKGROUND: According to only a handful of historical sources, Osmunda regalis, the royal fern, has been used already in the middle age as an anti-cancer remedy. To examine this ancient cancer cure, an ethanolic extract of the roots was prepared and analysed in vitro on its effectiveness against head and neck cancer cell lines. METHODS: Proliferation inhibition was measured with the MTT assay. Invasion inhibition was tested in a spheroid-based 3-D migration assay on different extracellular matrix surfaces...

The biogenic synthesis of metal nanomaterial offers an environmentally benign alternative to the traditional chemical synthesis routes. In the present study, the green synthesis of silver nanoparticles (AgNPs) from aqueous solution of silver nitrate (AgNO3) by using Nigella arvensis L. seed powder extract (NSPE) has been reported. AgNPs were characterized by UV-vis absorption spectroscopy with an intense surface plasmon resonance band at 435 nm which reveals the formation of nanoparticles. Fourier transmission infrared spectroscopy (FTIR) showed that nanoparticles were capped with plant compounds...

New strategies for the treatment of clear-cell renal cell carcinoma (ccRCC) are urgently needed. Recently, accumulating evidence has demonstrated that sinomenine hydrochloride (SH), extracted from the plant sinomenium acutum, has potent anti-cancer activity in multiple human malignant solid tumors. However, the underlying molecular mechanism by which SH treatment exerts its antagonizing tumorigenic effects has not been clearly elucidated. In this study, we showed that SH treatment exerted profound effects on cell growth in ccRCC in a dose- and time-dependent manner in vitro...

Plant polyphenols are important components of human diet and a number of them are considered to possess chemo-preventive and therapeutic properties against cancer. They are recognized as naturally occurring antioxidants, but also as pro-oxidant, pro-apoptotic, or chromosomal aberrations inducers, depending on their concentration and/or the stage of cell-cycle of the cells with which they interact. For these reasons, particular interest is devoted to knowing the total effects of polyphenols on the cell cycle and metabolism...

(no author information available yet)
Unlike conventional physical and chemical methods, the biogenic synthesis of gold nanoparticles (GNPs) is considered a green and non-toxic approach to produce biocompatible GNPs that can be utilized in various biomedical applications. This can be achieved by using plant-derived phytochemicals to reduce gold salt into GNPs. Several green synthesized GNPs have been shown to have antibacterial effects, which can be applied in wound dressings to prevent wound infections. Therefore, the aim of this study is to synthesize biogenic GNPs from the South African Galenia africana and Hypoxis hemerocallidea plants extracts and evaluate their antibacterial activity, using the Alamar blue assay, against bacterial strains that are known to cause wound infections...

Metastasis is the major hindrance in the treatment of all cancers, including laryngeal squamous cell carcinoma. Intensive researches are under way to identify the effective natural polyphenols with anti-metastatic ability for cancer treatment. Wheatgrass, an herbal plant has been reported to show anticancer effects. Hence, in this study, we aimed to analyze the anti-metastatic effect of methanol extract of wheatgrass (MEWG). The levels of metastatic marker proteins were determined by western blot. PI3K and AKT levels were determined by real time (RT)-PCR analysis...
