The aim of this narrative review is to describe treatment options for the posterior regions of the mandible and the maxilla, comparing short implants vs. longer implants in an augmented bone. The dental literature was screened for treatment options enabling the placement of dental implants in posterior sites with a reduced vertical bone height in the maxilla and the mandible. Short dental implants have been increasingly used recently, providing a number of advantages including reduced patient morbidity, shorter treatment time, and lower costs. In the posterior maxilla, sinus elevation procedures were for long considered to be the gold standard using various bone substitute materials and rendering high implant survival rates. More recently, implants were even placed without any further use of bone substitute materials, but the long-term outcomes have yet to be documented. Vertical bone augmentation procedures in the mandible require a relatively high level of surgical skill and allow the placement of standard-length dental implants by the use of autogenous bone blocks. Both treatment options, short dental implants, and standard-length implants in combination with vertical bone augmentation procedures, appear to result in predictable outcomes in terms of implant survival rates. According to recent clinical studies comparing the therapeutic options of short implants vs. long implants in augmented bone, the use of short dental implants leads to a number of advantages for the patients and the clinician.

Because the origins of stress are various, complex, and often indirectly-causing, reactions to stress are also various according to it's psychopathologies and mechanisms. For a proper management of stress, first of all accurate evaluation and diagnosis must be done. Then, treatment against the stress also can be considered, if necessary. In case of extreme stress, psychotropic drugs such as short-term anxiolytics or antidepressants can be used according to it's specific target symtoms. But long-term treatment of stress must be directed by increasing the individual's usual coping strategy or decreasing the externally causing stresses. Reactions to stress and drug interactions. which are not the whole of the biologic treatment strategy, are very important As a results, in our discussions, we ought to describe the issues by focusing the interactions between the drug and it's reaction to stress rather than the reaction to stress or drug itself and aimed at helping the proper treatment against the stress.

To investigate the effects of short-term treatment with tri-n-butyltin chloride (TBTCl) and bisphenol A (BPA) on the reproduction of striped field mice, the mice were intramuscularly injected with TBTCl or BPA immediately before the reproductive season and examined in the reproductive season after keeping them for 4 months. As a result, there were no differences between the control and the compound-treated groups regarding body weight in both sexes, the residual levels of the compounds in the adult males, and the gonadosomatic index (GSI) and the histological structures with LM and EM of the testes and epididymides in both the adult and young males. The infant mortality and abortion rate, however, were high in the TBTCl-treated groups and BPA-treated groups respectively, compared to the control group. Conclusively, it was suggested that short-term treatment with TBTCl or BPA in mice in the non-reproductive season might have inhibited the development of the uterine embryos or fetuses, although it did not induce accumulations of these compounds or affect the reproductive organs of adult and young (F1) males.

A patient with an epigastralgia was treated with Korean medicine for the short-term period of five days under admission care. In this case report, we discuss the efficacy and safety of short-term treatment using Korean medicine methods on a patient with an epigastralgia by evaluating a numerical rating scale, agastrointestinal symptom questionnaire, clinical features, and blood tests. The complex methods comprise purgation therapy using Crotonis Fructus, Korean herbal medication, acupuncture and moxibustion. Throughout the purgation therapy with Crotonis Fructus, the patient reported improvement in both her pain score and dyspepsia index. This case showed that Korean medicine acted not only fast, but also effective for treating epigastralgia patients diagnosed with functional dyspepsia.

Purpose: The marginal bone levels around implants following restoration are used as a reference for evaluating implant success and survival. Two design concepts that can reduce crestal bone resorption are the microthread and platform-switching concepts. The aims of this study were to analyze the placement of microthreaded and platform-switched implants and their short-term survival rate, as well as the level of bone around the implants. Methods: The subjects of this study were 27 patients (79 implants) undergoing treatment with microthreaded and platform-switched implants between October 2008 and July 2009 in the Dental Hospital of Yonsei University Department of Periodon-tology. The patients received follow-up care more than 6 months after the final setting of the prosthesis, at which time periapical radiographs were taken. The marginal bone level was measured from the reference point to the lowest observed point of contact between the marginal bone and the fixture. Comparisons were made between radiographs taken at the time of fixture installation and those taken at the follow-up visit. Results: During the study period (average of 11.8 months after fixture installation and 7.4 months after the prosthesis delivery), the short-term survival rate of microthreaded and platform-switched implants was 100% and the marginal bone loss around implants was $0.16{\pm}0.08$ mm, the latter of which is lower than the previously reported values. Conclusions: This short-term clinical study has demonstrated the successful survival rates of a microthread and platform-switched implant system, and that this system is associated with reduced marginal bone loss.

Soil extracellular enzyme plays a vital role in changing soil nitrogen (N) mineralization of rice field. However, the effects of soil extracellular enzyme activities (EEA) and microbial community composition response to N mineralization of rice field under short-term tillage treatment needed to be further explored. In this study, we investigated the impact of short-term (8-year) tillage practices on rhizosphere soil N transformation rate, soil enzyme activities, soil microbial community structure, and the N mineralization function gene abundances in double-cropping rice field in southern China. The experiment consisted of four tillage treatments: rotary tillage with crop straw input (RT), conventional tillage with crop straw input (CT), no-tillage with crop straw retention (NT), and rotary tillage with all crop straw removed as a control (RTO). The results indicated that the rhizosphere soil N transformation rate in paddy field under the NT and RTO treatments was significantly decreased compared to RT and CT treatments. In comparison to the NT and RTO treatments, soil protease, urease, β-glucosaminidase, and arginase activities were significantly improved by the CT treatment, as were abundances of soil sub, npr, and chiA with CT and RT treatments. Moreover, the overall diversity of soil bacterial communities in NT and RTO treatments was significantly lower than that in RT and CT treatments. Soil chitinolytic and bacterial ureolytic communities were also obviously changed under a combination of tillage and crop straw input practices.

Objectives: This study is a practice based research conducted to investigate the effectiveness and safety of a 5-day short-term diet program ('Oil-rescue' program) designed to reduce the adverse events and initial dropout rate in obesity treatment. Methods: We retrospectively analyzed 4 Korean medicine clinic patient data who completed 'Oil-rescue' program which is consisting of Gambi-hwan, Bium-hwan, Butgiban-hwan and Jayoon Kyungokgo. The weight change before and after participating 'Oil-rescue' program was primary outcome of our study. Changes in body mass index, body fat mass, skeletal muscle mass, body water content, lean body mass, protein, and minerals were also measured. Results: A total of 35 patients who satisfied the eligible criteria were finally included. The body weight decreased from 69.45±11.86 kg to 67.43±11.58 kg, a total of 2.02±1.03 kg (P<0.001). Body fat mass decreased from 25.77±7.45 kg to 24.98±7.26 kg, a total of 0.78±1.21 kg (P<0.001). Body mass index decreased from 26.39±3.64 kg/㎡ to 25.64±3.49 kg/㎡, a total of 0.75±0.41 kg/㎡. (P<0.001). A total of 15 patients had side effects such as diarrhea, abdominal pain, and insomnia, but all were mild. 16 out of 35 people switched to long-term obesity treatment programs. Conclusions: Through this retrospective practice based research, it was found that the 'Oil-rescue' program effectively reduced body weight, body fat, and body mass index, and the other obesity related parameters. It was a relatively safe and effective short-term obesity treatment program.

Appetite is inhibited by the anorexigenic neuropeptides POMC (proopiomelanocortin) and CART (cocaine-amphetamine-regulated transcript) in the hypothalamus. The present study was performed to examine the inhibitory effects of baicalin against food intake and the upregulation of POMC/CART. Short-term food intake (48 h) was significantly inhibited by treatment with baicalin (10 mg/kg, p<0.05) in C57BL/6 mice. Immunohistochemical analysis showed that baicalin upregulated POMC and CART levels in the arcuate nucleus of the hypothalamus. These effects were also examined using an in vitro system. pPOMC-Luc or pCART-Luc plasmids were transformed into mouse N29-2 neuronal and human SH-SY5Y cells, and the activities of baicalin were examined in these cells. Baicalin increased POMC and CART promoter-driven luciferase activity in a dose-dependent manner without cytotoxic effects. These results suggest that baicalin downregulates short-term food intake while upregulating POMC and CART expression.

The purpose of this study was to evaluate the effect of short-term paraquat treatment without insecticides on the enhancement in oleoresin of pitch pine (Pinus rigida M.) at various distances from the wound height. The trees were treated with 0.5, 2 and 4% paraquat solutions using the bore-hole technique. Duplicate cores from treated and untreated sides of treated trees were made at 5 height levels (-0.3, 0.0, 0.3, 0.9 and 1.5 m above the wound height) at 3 months after treatment. The alcohol-benzene extractives based on unextracted oven-dry cores were taken as oleoresin contents. The results were as follows: 1. The effect of oleoresin enhancement at wound height were not affected by paraquat concentration. 2. Ascending distance of the enhancing effects above the wound height was directly related to paraquat concentration. Only in 4% paraquat treated trees, the effect extended to 1.5 m above the wound height. 3. As a result of examining descending distance of the enhancing effects at 0.3 m below the wound height, the effects extended to there in 4% and 2% paraquat treated trees.
