Cytotoxic Effects of Some Flavonoids and Imatinib on the K562 Chronic Myeloid Leukemia Cell Line: Data Analysis Using the Combination Index Method.

Background: Flavonoids are natural compounds with antioxidant, anticarcinogenic, and anti-inflammatory effects.

Aims: To determine the cytotoxic effects of flavonoids and drug resistance related to P-gp on K562 human chronic myeloid leukemia cells. We also aimed to evaluate the therapeutic potential of imatinib and flavonoid combinations.

"It doesn't exist…": negotiating palliative care from a culturally and linguistically diverse patient and caregiver perspective.

Background: The end of life represents a therapeutic context that acutely raises cultural and linguistic specificities, yet there is very little evidence illustrating the importance of such dynamics in shaping choices, trajectories and care practices. Culture and language interplay to offer considerable potential challenges to both patient and provider, with further work needed to explore patient and caregiver perspectives across cultures and linguistic groups, and provider perspectives. The objective of this study was to develop a critical, evidence-based understanding of the experiences of people from Culturally and Linguistically Diverse (CALD) backgrounds, and their caregivers, in a palliative care setting.

Effects of Luteolin on Liver, Kidney and Brain in Pentylentetrazol-Induced Seizures: Involvement of Metalloproteinases and NOS Activities.

Objective: Flavonoids are an important group of recognized antioxidants in plants. Luteolin (LUT) is a natural flavonoid in the plant kingdom. This study was aimed to investigate the effects of the LUT in the liver, kidney and brain of pentylentetrazol (PTZ)-induced seizure and the relationship between nitric oxide synthases (iNOS, eNOS) and matrix metalloproteinases (MMP2, MMP9).

Crataegus tanacetifolia leaf extract prevents L-NAME-induced hypertension in rats: a morphological study.

Crataegus (hawthorn) has long been used as a folk medicine all around the world. Most of the studies with Crataegus species focus on effects on heart failure and cardiovascular disease. The pharmacological effects of Crataegus have been attributed mainly to the content of flavonoids, procyanidin, aromatic acid and cardiotonic amines.

Cardioactive diterpenes from the roots of Salvia eriophora.

From the roots of Salvia eriophora (Lamiaceae), a new compound, 4,14-dihydroxysaprorthoquinone, was isolated in addition to ten known diterpenoids. The structure of the new compound was established by spectroscopic analysis. The crude extract of the plant and the isolated diterpenoids were tested for their cardiovascular activities using Wistar Albino rats.
