  • The field of stem cell research has been rapidly expanding. Although the clinical usefulness of research remains to be ascertained through human trials, the use of stem cells as a therapeutic option for currently disabling diseases holds fascinating potential. Many pediatric gastrointestinal tract diseases have defect in enterocytes, enteric nervous system cells, smooth muscles, and interstitial cells of Cajal. Various kinds of therapeutic trials using stem cells could be applied to these diseases. This review article focuses on the recent achievements in stem cell applications for pediatric gastrointestinal tract diseases.

  • The efficient Erythropoietin(EPO)-expression system in mammalian cells is required for massive production for therapeutic use. Ammonium ion is a major problem in the production of useful proteins by cultured animal cells and therefore it is of importance to devise a system by which a high productivity of human therapeutic recombinant protein can be maintained or enhanced under low ammonium concentration.

  • Molecular targeting may be defined as the specific concentration of a diagnostic or therapeutic tracer by its Interaction with a molecular species that is distinctly present or absent in a disease state. Monoclonal antibody (mAb) is one of the successful agents for targeted therapy in cancer. To enhance the therapeutic effect, the concept of targeting radionuclides to tumors using radiolabeled mAbs against tumor-associated antigens, radioimmunotherapy, was proposed. The efficacy of radioimmunotherapy, however, has to be further optimized. Several strategies to improve targeting of tumors with radiolabeled mAbs have been developed, such as the use of mAb fragments, the use of high-affinity mAbs, the use of labeling techniques that are stable in vivo, active removal of the radiolabeled mAb from the circulation, and pretargeting strategies. Until now, however, there are many kinds of obstacles to be solved in the use of mAb for the targeted therapy. Major technical challenges to molecular targeting are related to the rapid and specific delivery of tracers to the target, the elimination of unwanted background activity, and the development of more specific targets to create a cytocidal effect. further development of this field will be determined by success in solving these challenges.

  • There is considerable interest in $^{188}Re$ due to its favorable properties as a therapeutic radionuclide $^{188}Re$ and $^{99m}Tc$ act as a matched pair because of their similar chemical properties, and therefore methods of labeling with $^{99m}Tc$ can be applied to the labeling with $^{188}Re$. With appropriately chosen agents as carriers of $^{188}Re$, the labeling can be readily carried out using $^{188}ReO_4^-$ in the presence of a reducing agent. $^{188}Re$ radio-pharmaceuticals based on $^{99m}Tc$ complexes have been synthesized and are currently being studied for clinical use. Some of them are shown to be suitable for therapeutic use and promising for radiotherapy in nuclear medicine.

  • The NFAT family of transcription factors plays pivotal roles in the development and function of the immune system. Their activation process is tightly regulated by calcium-dependent phosphatase calcineurin and has been a target of the immunosuppressive drugs cyclosporin A and FK-506. Although the clinical use of these drugs has dramatically increased the success of organ transplantation, their therapeutic use is limited by severe side effects. Recent studies for the calcineurin/NFAT signaling pathway have identified a number of cellular proteins that inhibit calcineurin function. Specific peptide sequences that interfere with the interaction between calcineurin and NFAT have also been characterized. Moreover, diverse approaches to identify small organic molecules that modulate NFAT function have been performed. This review focuses on the recent advances in our understanding of the inhibitory modulation of NFAT function, which may open up the additional avenues for immunosuppressive therapy.

  • Tamoxifen is a central component of the treatment of estrogen receptor (ER)-positive breast cancer as a partial agonist of ER. It has been clinically used for the last 30 years and is currently available as a chemopreventive agent in women with high risk for breast cancer. The most challenging issue with tamoxifen use is the development of resistance in an initially responsive breast tumor. This review summarizes the roles of ER as the therapeutic target of tamoxifen in cancer treatment, clinical values and issues of tamoxifen use, and molecular mechanisms of tamoxifen resistance. Emerging knowledge on the molecular mechanisms of tamoxifen resistance will provide insight into the design of regimens to overcome tamoxifen resistance and discovery of novel therapeutic agents with a decreased chance of developing resistance as well as establishing more efficient treatment strategies.

  • We explored the indigenous local knowledge associated with the use of snails by Baiga people in Baihar tehsil of Balaghat district in central India through interview with a semi-structured questionnaire. Results revealed that Baiga people widely accept snails of 3-5 morpho-groups belonging to Ampullariidae, and Viviparidae family as food. Besides, use of snail as therapeutic agents for ailments like body ache, joint pain, digestion, weakness of bones etc. were found common. Hand-picking of snails from the wild environments as well as agriculture field was the primary way of harvesting edible snails. We advocate the development of a farming system for the continuous supply of snails as a food resource, advancement of scientific investigation of functional properties of them, economic progress of the region and therefore the overall sustainability.

  • The amyloid hypothesis has been considered a major explanation of the pathogenesis of Alzheimer disease. However, failure of phase III clinical trials with anti-amyloid-beta monoclonal antibodies reveals the need for other therapeutic approaches to treat Alzheimer disease. Compared to its relatively short history, optogenetics has developed considerably. The expression of microbial opsins in cells using genetic engineering allows specific control of cell signals or molecules. The application of optogenetics to Alzheimer disease research or clinical approaches is increasing. When applied with gamma entrainment, optogenetic neuromodulation can improve Alzheimer disease symptoms. Although safety problems exist with optogenetics such as the use of viral vectors, this technique has great potential for use in Alzheimer disease. In this paper, we review the historical applications of optogenetic neuromodulation with gamma entrainment to investigate the mechanisms involved in Alzheimer disease and potential therapeutic strategies.

  • The purpose of this study is to understand the importance of exterior environments and to identify the design guidelines for the therapeutic garden for cognitively impaired seniors with Alzheimer's disease and related dementias. The data was collected from 4 Adult Day Care Centers, 2 Nursing Homes, & 1 Assisted living in the U.S.A. from 2001 to 2002 by interview and the floor plan about the outdoor space. Although some may believe that patients with Alzheimer's disease and related disorders are unresponsive to environment, evidence shows that environments especially designed for cognitively impaired seniors can maintain or increase their level of functioning. The use of specially designed exterior environments nay have in reducing incidents of aggressive behavior, and contributing significantly to a wanderer management program. The checklist includes 6 dimensions: safety environment, various sensual stimulations, social interactions, wandering, privacy, and support orientation and reality. The results indicated that the exterior environment have to support wandering behavior, orientation and reality.
