Abstract
BackgroundSelective delivery of anticancer agents to target areas in the body is desirable to minimize the side effects while maximizing the therapeutic efficacy. Anthracycline antibiotics such as doxorubicin (DOX) are widely used for treatment of a wide variety of solid tumors.This study evaluated the potential of a polymeric micellar formulation of doxorubicin as a nanocarrier system for targeted therapy of a folate-receptor positive human ovarian cancer cell in line.ResultsDOX-conjugated targeting and non-targeting micelles prepared by the dialysis method were about 188 and 182 nm in diameter, respectively and their critical micelle concentration was 9.55 μg/ml. The DOX-conjugated micelles exhibited a potent cytotoxicity against SKOV3 human ovarian cancer cells. Moreover, the targeting micelles showed higher cytotoxicity than that of non-targeting ones (IC50 = 4.65 μg/ml vs 13.51 μg/ml).ConclusionThe prepared micelle is expected to increase the efficacy of DOX against cancer cells and reduce its side effects.

Obesity has reached epidemic proportions and is still escalating at an alarming rate worldwide
Obesity is associated with chronic activation of low-grade inflammation [3], which is implicated in the pathogenesis of obesity-associated diseases including insulin resistance, type-2 diabetes (T2D) [4, 5] and cardiovascular disease [6, 7]
A numerous of studies has been shown that shortchain fatty acids (SCFAs) inhibit inflammation with focus on butyrate and to a lesser extent on acetate and Propionic Acid (PA), [16]
Summary
Obesity has reached epidemic proportions and is still escalating at an alarming rate worldwide. In Palestine the prevalence of obesity has been shown to be approximately 4. The etiology of obesity and low-grade inflammation is complex and involves intrinsic and extrinsic factors. The colonization of germ-free mice with microbiota derived from obese mice results in significantly greater adiposity than colonization with microbiota from lean mice [12]. Prebiotic diets such as fructans [13] are associated with general better health, including the decrease in body weight, fat mass and the severity of T2D [14,15,16]. The factors that influence the composition and metabolism of intestinal
