Despite advances in radiation delivery techniques, side effects of radiation therapy due to radiation exposure of normal tissues are common and can limit the deliverable dose to tumors. Significant interests lie in pharmacologic modifiers that may protect against normal tissue toxicity from cancer treatment while simultaneously enhancing the tumor response to therapy. While no such treatments are available in the clinic, this is an area of active preclinical and clinical research. This review summarizes research studies that provide evidence to indicate that tocotrienols, natural forms of vitamin E, are potent radiation protectors and may also have antitumor effects. Hence, several current clinical trials test tocotrienols as concomitant treatment in cancer therapies.

Resorcimoline as a Novel Therapeutic Agent Attenuates Ischemia-Reperfusion Injury in Hind Extremities.
Ann Vasc Surg

Department of Cardiovascular Surgery, Oita University Faculty of Medicine, Oita, Japan.
Background: Acute ischemia in the hind extremities is a dangerous disease that causes irreversible damage. Revascularization procedures are important to prevent muscle damage, but these treatments may induce additional damage, also known as ischemia-reperfusion injury. The role of free radicals as pivotal mediators of ischemia-reperfusion injury remains a prominent hypothesis.

The present study was to investigate the effect of the astaxanthin high internal phase Pickering emulsion (H-AXT) on DEHP-induced liver lipid metabolism disorder and to demonstrate its possible protective mechanism. We have developed an antioxidant activity emulsion system to deliver astaxanthin into the liver to maximize its ability to protect the liver. In vitro, H-AXT intervention inhibited oxidative stress restored the level of mitochondrial membrane potential to 90 % of that of normal LO2 cells, and alleviated the imbalance of energy metabolism by protecting mitochondrial structure and function.

Bacteriocin can effectively improve the gut inflammation for their superior antibacterial activity. However, its inherent attributes, such as easily degraded and off-target effect in the gastrointestinal environment, make bacteriocins' efficient oral delivery a great challenge. Herein, a pectin/4-carboxyphenylboric acid/carboxymethyl chitosan (PEC/CPBA/CMCS) hydrogel microbead targeted oral delivery system was innovatively developed for the plantaricin RX-8 protective delivery, precisely targeted inflammatory microenvironment (IME) and sustained released plantaricin RX-8 by pH/ROS dual stimulation response.

Isoniazid and rifampicin co-therapy are the main causes of anti-tuberculosis drug-induced liver injury (ATB-DILI) and acute liver failure, seriously threatening human health. However, its pathophysiology is not fully elucidated. Growing evidences have shown that fibroblast growth factors (FGFs) play a critical role in diverse aspects of liver pathophysiology.
