in order to evaluate the effects of drought stress and spraying of salysilic acid and chitosan on photosynthetic pigments and antioxidant enzymes of safflower an experiement was conducted as split plot randomized complete block design at the zabol university research farm in zabol, south iran during 2012. treatments were drought stress at three levels; irrigation when the soil moisture level dr...

BACKGROUND Obese adipose tissue (AT) inflammation is characterized by dysregulated adipokine production and immune cell accumulation. Cluster of differentiation (CD) 8+ T cell AT infiltration represents a critical step that precedes macrophage infiltration. n-3 (ω-3) Polyunsaturated fatty acids (PUFAs) exert anti-inflammatory effects in obese AT, thereby disrupting AT inflammatory paracrine sig...

Three-year-old Angus x Gelbvieh beef cows nutritionally managed to achieve a BCS of 4 +/- 0.07 (479.3 +/- 36.3 kg of BW) or 6 +/- 0.07 (579.6 +/- 53.1 kg of BW) at parturition were used in a 2-yr experiment (n = 36/yr) to determine the effects of prepartum energy balance and postpartum lipid supplementation on cow and calf performance. Beginning 3 d postpartum, cows within each BCS were assigne...

Breast cancer accounts for 22.9% of all types of cancer in females worldwide. Safflower polysaccharide (SPS) is an active fraction purified from safflower petals (Carthamus tinctorius L). The present study investigated the effects of safflower polysaccharide on the proliferation and metastasis of breast cancer cells. Cell viability was analyzed using an MTT assay following treatment of the MCF‑...

Glucagon like peptide-1 (GLP-1) and serotonin are both involved in food intake regulation. GLP-1 release is stimulated upon nutrient interaction with G-protein coupled receptors by enteroendocrine cells (EEC), whereas serotonin is released from enterochromaffin cells (ECC). The central hypothesis for the current study was that nutrient-induced GLP-1 release from EECs is modulated by serotonin t...

Salicylic acid (SA) plays an important role in regulating leaf senescence. However, the molecular mechanism of senescence safflower ( Carthamus tinctorius ) is still elusive. In this study, we found that bHLH transcription factor (TF) CtbHLH41 significantly delayed and inhibited expression senescence-related genes. order to explore how promotes senescence, carried out yeast two-hybrid screening...

BACKGROUND The fatty acid composition of the phospholipids in sarcolemma may significantly influence cell membrane functions. We evaluated the effects of dietary fat on the pharmacodynamics of the antiarrhythmic drug propafenone in isolated, perfused rabbit hearts. METHODS AND RESULTS Three groups of weanling rabbits (n = 9 each group) were fed diets of 10% wt/wt lard, fish oil, or safflower ...
