Ginseng effectively regulates the immune response and the hormonal changes due to stress, thus maintaining homeostasis. In addition to suppressing the occurrence of psychological diseases such as anxiety and depression, ginseng also prevents stress-associated physiological diseases. Recent findings have revealed that ginseng is involved in adjusting the hypothalamic-pituitary-adrenal axis and controlling hormones, thus producing beneficial effects on the heart and brain, and in cases of bone diseases, as well as alleviating erectile dysfunction. Recent studies have highlighted the potential use of ginseng in the prevention and treatment of chronic inflammatory diseases such as diabetes, rheumatoid arthritis, and allergic asthma. However, the mechanism underlying the effects of ginseng on these stress-related diseases has not been completely established. In this review, we focus on the disease pathways caused by stress in order to determine how ginseng acts to improve health. Central to our discussion is how this effective and stable therapeutic agent alleviates the anxiety and depression caused by stress and ameliorates inflammatory diseases.

Tankyrases are multifunctional poly (ADP-ribose) polymerases that regulate a variety of cellular processes including WNT signaling, telomere maintenance, regulation of mitosis, and many others. Tankyrases interact with target proteins and regulate their interactions and stability through poly (ADP-ribosyl) ation. In addition to their roles in telomere maintenance and regulation of mitosis, tankyrase proteins regulate tumor suppressors such as AXIN, PTEN, and AMOT. Therefore, tankyrases can be effective targets for cancer treatment. Tankyrase inhibitors could affect a variety of pathways that are carcinogenic (essential for the unlimited proliferation of human cancer cells), including WNT, AKT, YAP, telomere maintenance, and regulation of mitosis. Recently, new aspects of the function and mechanism of tankyrases have been reported and several tankyrase inhibitors have been identified. Also, it has been proposed that the combination of conventional chemotherapy agents with tankyrase inhibitors may have synergistic anti-cancer effects. Based on this, it is expected that more advanced and improved tankyrase inhibitors will be developed, enabling new therapeutic strategies against cancer and other tankyrase linked diseases. This review discusses tankyrase function and the role of tankyrase inhibitors in the treatment of cancer.

Many conventional anticancer drugs display relatively poor selectivity for neoplastic cells, in particular for solid tumors. Furthermore, expression or development of drug resistance, increased glutathione transferases as well as enhanced DNA repair decrease the efficacy of these drugs. Research efforts continue to overcome these problems by understanding these mechanisms and by developing more effective anticancer drugs. Cyclophosphamide is one of the most widely used alkylating anticancer agents. Because of its unique activation mechanism, numerous bioreversible prodrugs of phosphramide mustard, the active species of cyclophosphamide, have been investigated in an attempt to improve the therapeutic index. Solid tumors are particularly resistant to radiation and chemotherapy. There has been considerable interest in designing drugs selective for hypoxic environments prevalent in solid tumors. Much of the work had been centered on nitroheterocyclics that utilize nitroreductase enzyme systems for their activation. In this article, recent developments of anticancer prodrug design are described with a particular emphasis on exploitation of selective metabolic processes for their activation.

The common disorder called tennis elbow exhibits typical clinical characteristics, i.e. painful condition at the lateral aspect of elbow joint on resisted wrist extension. However an exact cause for this painful condition has not yet been established. Many observers believe that the usual lesion of tennis elbow is a partial rupture of the extensor tendon at the tenoperiosteal juction on the lateral epicondyle of humerus. However the mechanism of the tendon rupture has never been explained. Conservative treatments on the tender area have been the most common therapeutic modalities for pain relief of tennis elbow. Based on my clinical experiences and anatomical studies, I discerned that tennis elbow is a periostitis of lateral epicondyle of humerus secondary to spastic contraction of muscular belly of extensor carpi radialis after over-stretched injury. Therefore, spasmolytic treatment on the extensor carpi radialis muscle provided a favorable result for permanent relief for tennis elbow pain.

Orofacial pain is a common complaint of patients that causes distress and compromises the quality of life. It has many etiologies including trauma, interventional procedures, nerve injury, varicella-zoster (shingles), tumor, and vascular and idiopathic factors. It has been demonstrated that the sympathetic nervous system is usually involved in various orofacial pain disorders such as postherpetic neuralgia, complex regional pain syndromes, and atypical facial pain. The stellate sympathetic ganglion innervates the head, neck, and upper extremity. In this review article, the effect of stellate ganglion block and its mechanism of action in orofacial pain disorders are discussed.

There has been continuing interest in the development of synthetic and natural compounds that modify the immune response particularly for the treatment of AIDS and cancer. During the past fifty years, numerous scientific studies have been published on ginseng (Foster and Chongxi, 1992). Modern human studies have investigated preventive effect of ginseng on several kinds of cancer (Yun et al, 1993,Yun, 1995,Yun and Choi, 1998), its long term immunological effect on HIV patients (Sankang, 1989, Cho et al, 1997), its effect on cell mediated immune functions in healthy volunteers (Scaglione et al, 1990). Similarly non clinical studies on animal model system have studied the chemopreventive action of ginseng on cancer (Kumar, 1993,98) and immunological properties of ginseng (Kim et al, 1990, Tomoda et al, 1993, Yun et al, 1993, Mizuno et al, 1994,Lee et al, 1997, Park et al, 2001,Yoshikawa et al, 2001, Wang et al, 2001). The precise mechanism of action of ginseng, however, not clearly understood. Considering its wide-ranging therapeutic effects, this study is being undertaken to elucidate the general mode of action of ginseng, especially to test our hypothesis that its biological action may be mediated by the immune system.

The expansion and folding of the cerebral cortex occur during brain development and are critical factors that influence cognitive ability and sensorimotor skills. The disruption of cortical growth and folding may cause neurological disorders, resulting in severe intellectual disability and intractable epilepsy in humans. Therefore, understanding the mechanism that regulates cortical growth and folding will be crucial in deciphering the key steps of brain development and finding new therapeutic targets for the congenital anomalies of the cerebral cortex. This review will start with a brief introduction describing the anatomy of the brain cortex, followed by a description of our understanding of the proliferation, differentiation, and migration of neural progenitors and important genes and molecules that are involved in these processes. Finally, various types of disorders that develop due to malformation of the cerebral cortex will be discussed.

Background: Inflammation is a host-defensive innate immune response to protect the body from pathogenic agents and danger signals induced by cellular changes. Although inflammation is a host-defense mechanism, chronic inflammation is considered a major risk factor for the development of a variety of inflammatory autoimmune diseases, such as rheumatic diseases. Rheumatic diseases are systemic inflammatory and degenerative diseases that primarily affect connective tissues and are characterized by severe chronic inflammation and degeneration of connective tissues. Ginseng and its bioactive ingredients, genocides, have been demonstrated to have antiinflammatory activity and pharmacological effects on various rheumatic diseases by inhibiting the expression and production of inflammatory mediators. Methods: Literature in this review was searched in a PubMed site of National Center for Biotechnology Information. Results: The studies reporting the preventive and therapeutic effects of ginseng and ginsenosides on the pathogenesis of rheumatic diseases were discussed and summarized. Conclusion: Ginseng and ginsenosides play an ameliorative role on rheumatic diseases, and this review provides new insights into ginseng and ginsenosides as promising agents to prevent and treat rheumatic diseases.

Although many studies have reported that the breakdown of the blood-brain barrier (BBB) represents one of the major pathological changes in aging, the mechanism underlying this process remains relatively unexplored. In this study, we described that acid sphingomyelinase (ASM) derived from endothelial cells plays a critical role in BBB disruption in aging. ASM levels were elevated in the brain endothelium and plasma of aged humans and mice, resulting in BBB leakage through an increase in caveolae-mediated transcytosis. Moreover, ASM caused damage to the caveolae-cytoskeleton via protein phosphatase 1-mediated ezrin/radixin/moesin dephosphorylation in primary mouse brain endothelial cells. Mice overexpressing brain endothelial cell-specific ASM exhibited acceleration of BBB impairment and neuronal dysfunction. However, genetic inhibition and endothelial specific knock-down of ASM in mice improved BBB disruption and neurocognitive impairment during aging. Results of this study revealed a novel role of ASM in the regulation of BBB integrity and neuronal function in aging, thus highlighting the potential of ASM as a new therapeutic target for anti-aging.
