  • Even the pharmacotherapy is more effective than placebo for the treatment of depression, the outcome of pharmacoltherapy remains unsatisfactory for many patients. Apart from side effects, there are two major limitations of antidepressant therapy. One is the delayed onset of improvement and another is partial response. In order to address these clinical dilemmas, many psychiatrists more commonly employ add-on therapy. In past, the practice of using multiple drugs to enhance treatment response was called polypharamcy, and was disparaged as poor clinical practice. However, with improved understanding of how drugs affects the central nervous system and increased communication in journals and on computer networks about the relative merits of specific combinations, the scientific basis for the combining drugs is being defined. Indeed, the use of multiple medications as a stratege to enhance response has become both acceptable and widespread now a days. It is now referred to more positively as add-on therapy, co-medication, combination therapy, or drug augmentation. Thus, as the methods of practical strategies for treatment of depression, switching classes antidepressant drugs, combination therapy, augmentation strategies and brief treatment algorithm will be presented with items of considerations. However, when combination of drugs being tried, knowledges about the action of mechanism, pharamcokinetics, and pharmacodynamics are essential to cope with the possible adversive reactions and to get the appropriate responses for the treatment of depressive symptoms.

  • Electron injection enhancement at OLED (organic light-emitting diodes) cathode side has mostly been achieved by insertion of a low work function layer between metal electrode and emissive layer. We investigated the interfacial chemical reactions and electronic structures of alkaline-earth metal (Ca, Ba)/Alq3 [tris(8-hydroxyquinolinato)aluminium] and Ca/BaF2/Alq3 using in-situ X-ray & ultraviolet photoelectron spectroscopy. The alkaline-earth metal deposited on Alq3 generates two energetically separated gap states in sequential manner. This phenomenon is explained by step-by-step charge transfer from alkali-earth metal to the lowest unoccupied molecular orbital (LUMO) states of Alq3, forming new occupied states below Fermi level. The BaF2 interlayer initially prevents from direct contact between Alq3 and reactive Ca metal, but it is dissociated into Ba and CaF2. However, as the Ca thickness increases, the Ca penetrates the interlayer to directly participate in the reaction with underlying Alq3. The influence of the multiple gap state formation by the interfacial chemical reaction on the OLED performance will be discussed.

  • Hh proteins represent a new signaling paradigm in metazoan development. In species ranging from fruit flies to humans, Hh proteins mediate multiple processes vital to appropriate pattern formation in the developing embryo. Hh proteins undergo an autoprocessing event in which the full-length protein is cleaved into N-terminal and C-terminal domains (Hh-N and Hh-C, respectively), and a cholesterol moiety becomes covalently attached to Hh-N. All known signaling activities of Hh proteins are mediated by Hh-N while both the cleavage and cholesterol transfer reactions are mediated by Hh-C. The cholesterol attached to Hh-N is required to retrict the range of Hh signaling and may be involved in ensuring appropriate reception of the Hh signal in target tissues. Disruptions of Hh signaling pathways lead to severe developmental defects in newborns and cancers in adults. While studies of Hh proteins have yielded a wealth of new insight into the molecular mechanisms of metazoan development, many outstanding questions concerning Hh signaling mechanisms ensure that unraveling the secrets of this molecule will keep scientists well entertained for the foreseeable future.

  • A 13-year old male dog with right forelimb lameness, invisible swelling, anorexia and mild depression was referred to Veterinary leaching Hospital, College of Veterinary Medicine, Kyungpook National University. On forelimb radiographic views, periosteal and endosteal proliferation and cortical lysis and extremely aggressive and amorphous periosteal reactions were located along the metaphyseal region of the proximal humerus. Cytologic and histopathologic examinations after amputation showed anaplastic mesenchymal cells that produced osteoid changes, poorly differentiated osteoblast and osteoclast. And also, it included the neoplastic cells with large nucleoli, multiple nucleoli that differ in size and cytoplasm with several clear vacuoles. Based on the physical examination and laboratory, radiolographic, cytologic and histopathologic findings, this case was diagnosed as osteosarcoma of the proximal humerus.

  • A Cu(II) complex with an three nitrogens and one sulfur coordination environment was synthesized and characterized. Its redox potential was observed at 0.483 V vs. NHE, very similar to that of a Cu-containing fungal enzyme, galactose oxidase, which catalyzes the oxidation of alcohols to corresponding aldehydes with the concomitant reduction of molecular oxygen to water. The Cu(II) complex selectively oxidizes the benzylic alcohols using TEMPO/$O_2$ under mild reaction conditions to corresponding aldehydes without forming any over-oxidation product. Moreover, the catalyst can be recovered and reused multiple times for further oxidation reactions, thus minimizing the waste generation.

  • Several toxic substances have been detected in plants which are responsible for animal and human diseases. Bracken fern (Pteridium aquilinum) is one example, widely distributed in many parts of the world. It is known to cause cancer in humans and other animals. In fact, man can be directly or indirectly exposed to the danger by consuming fern, contaminated water, milk, meat, and spore inhalation. Experimental studies have shown an association between bracken exposure and gastric cancer, and research has shown genotoxic and cytotoxic effects in vitro. This paper describes and reviews toxic, carcinogenic, genotoxic/cytotoxic, and immunomodulatory effects of bracken and included possible toxic agents. The chemistry of Ptaquiloside (PT) reactions is emphasized, along with bracken problems in livestock, possible pathways of exposure in man, and control for human health.

  • The elderly are more likely to have chronic medical conditions that require multiple drug therapies. Purposes of this study are to reveal necessity of elderly patient education by pharmacists, and to induce appropriate policy. We carried out literature research. Taking several drugs together increases risk of drug interactions and adverse reactions. We suggest that pharmacists have the legal authority to monitor prescription for efficient drug management, pharmacovigilance system be efficiently operated, and medication education fee be provided to allow pharmacists give more time to the elderly.

  • In the combustion modeling of non-premixed flames, the mixture fraction conserved scalar approach is widely utilized because reactants are mixed at the molecular level before burning and atomic elements are conserved in chemical reactions. In the mixture fraction approach, combustion process is simplified to a mixing problem and the interaction between chemistry and turbulence could be modelled by many sophisticated combustion models including the flamelet model and CMC. However, most of the mixture fraction approach is restricted to one mixture system. In this study, the flamelet model based on the two-feed system is extended to the multiple fuel-feeding systems by the two mixture fraction conserved scalar approach.
