Objective: The purpose of this study was to further the empirical evidence regarding exercise as an effective alternative to surgery for treating patients with low to moderate hallux valgus. Method: A total of 20 students with low to moderate hallux valgus participated in this study for six weeks. Participants were selected according to foot-print. All participants exercised using a combination of Elastic-band and Short Foot Exercises twice a week for thirty minutes each time. Measurements were taken at week 0 and week 6 for plantar foot pressure, toe angle and balance. The data was processed using a paird t-test. Results: There were significant differences in pretest and posttest measurements for balance. However there were no significants differences in plantar foot pressure and toe angle. Conclusion: Although our study did not support the effect of exercises on plantar foot pressure and toe angle, we did show evidence that exercise was effective for balance. In order to increase the effectiveness of this exercise program, patients need to be more aware of the footwear they use in their daily lives so as to contribute to the contribute to the overall effectiveness of treating low to moderate hallux valgus and offer an alternative to surgery.

Introduction : One of the important domains in OT is performance skills which include sensory perceptual skills, motor and praxis skills, emotional regulation skills, cognitive skills, and communication/social skills. All of these skills are support ed by integrated neurological processes. Body : Stereology robust tool when employed to investigate morphological changes in neurons, cortex area, and specific parts of brain involved in special brain function. Stereology is an interdisciplinary field focused or analyzing biological tissue with the three-dimensional interpretation of planer sections by using estimating method and mathematically unbiased sampling. With the unbiased stereological method based on probability theory, researchers can estimate morphological and anatomical changes in biological reference areas accurately and efficiently. Changes in anatomical and cytoarchitectural parameters, such as volume, number, and length, affect specific brain function related to the brain area. Occupational therapists provide treatment to improve functions for participation of occupation in neurological disorder. The functional improvements in neurological disorder reflect neurobiological changes because functional difficulties, such as motor cognitive disorder, are due to neurological disturbances. Thus, combination of two kinds of evidence, neurological changes and functional improvement, provide fundamental evidence for OT intervention in neurological disorder. Even though most of stereological studies are in animal model and in postmortem human because of practical and ethical issues, stereology provides fundamental knowledge to support OT theory and practice. Conclusion : Therefore, stereology informs translation from neuroscience to OT based on structure-function relationship in performance skills and experience-dependent neural plasticity.

Purpose: Ginger (Zingiber officinale) has been widely used as an antiemetic agent. This systematic review was aimed at evaluation of the effect of dried ginger powder supplementation on improvement of nausea and vomiting associated with early pregnancy or motion sickness. Methods: We searched Pubmed, Cochrane, Science Direct, and KISS (Korean studies Information Service System) using keywords such as ginger or Zingiber officinale in combination with nausea, vomiting, motion sickness, or pregnancy, published in March 2013. Results: The strength of the evidence was evaluated on the selected 12 RCTs (randomized controlled trials). Eleven trials including 2,630 subjects showed that supplementation with dried ginger powder resulted in significant improvement of nausea or vomiting related to early pregnancy or motion sickness. Among the nine studies including 809 women in early pregnancy before 20 weeks of gestation, ginger supplementation was superior to placebo in five studies (n = 305), and as effective as positive control (vitamin $B_6$ or dimenhydrinate) in four studies (n = 504). Ginger intake significantly reduced the episodes or severity of vomiting related to motion sickness compared to placebo or showed the same effect as several antiemetic drugs in two studies (n = 1,821). Conclusion: Our findings added evidence indicating that ginger powder supplements might improve the symptoms of nausea or vomiting related to early pregnancy or motion sickness without significant adverse events.

Sarcopenia, a common clinical syndrome in older adults, is defined as decreased muscle mass, strength, and physical performance. Since sarcopenia is associated with the incidence of functional decline, falls, and even mortality in older adults, researchers and health care providers have been keen to accumulate clinical evidence to advocate the screening and prevention of sarcopenia progression in older adults. The factors that may accelerate the loss of muscle mass and function include chronic diseases, inactivity, and deficiency in appropriate nutritional support. Among these, nutritional support is considered an initial step to delay the progression of muscle wasting and improve physical performance in community-dwelling older adults. However, a nationwide study suggested that most Korean older adults do not consume sufficient dietary protein to maintain their muscle mass. Furthermore, considering age-associated anabolic resistance to dietary protein, higher protein intake should be emphasized in older adults than in younger people. To develop a dietary protein recommendation for older adults in Korea, we reviewed the relevant literature, including interventional studies from Korea. From these, we recommend that older adults consume at least 1.2 g of protein per kg of body weight per day (g/kg/day) to delay the progression of muscle wasting. The amount we recommend (1.2 g/kg/day) is 31.4% higher than the previously suggested recommended daily allowance (i.e., 0.91 g/kg/day) for the general population of Korea. Also, evidence to date suggests that the combination of exercise and nutritional support may enhance the beneficial effects of protein intake in older adults in Korea. We found that the current studies are insufficient to build population-based guidelines for older adults, and we call for further researches in Korea.

The Wugang banded iron formation (BIF) is located within the Taihua complex at the southern margin of the North China Craton (NCC). In this study, we analyzed major elements and rare-earth elements in iron ores from the Wugang BIF, to study the type of BIFs and their formation mechanism in combination with previously-published data from the literature. We found that the iron ores from the Wugang BIF display two types of banding textures, which can be described as weak banding or no banding. The samples are composed of coarse-grained magnetite, quartz, pyroxene, and amphibole. Based on our geochemical results, mixing of a hydrothermal fluid with sea water led to the precipitation of the Wugang BIF, and there is evidence of crustal contamination. These results, combined with previous literature data, almost all of the iron ores lack Ce anomalies, though some samples show negative Ce anomalies. Our results indicate that the Wugang BIF was formed in a dominantly reducing environment, although the surfaces were relatively oxidized. Geochemical evidence suggests that the Wugang BIF iron ores were formed in a near-shore continental-shelf environment or in a back-arc basin. The BIF is known as interbedded with migmatite, amphibole gneiss, minor quartz and marble, which indicating lack of volcanic materials input. This study, combined with previous results on geochemical interpretation of related wall rock of Wugang BIF, demonstrated that Wugang BIF belongs to Superior-type BIF.

Objectives: Frozen shoulder (FS) is one of the most challenging shoulder disorders for patients and clinicians. Its symptoms mainly include any combination of stiffness, nocturnal pain, and limitation of active and passive glenohumeral joint movement. Conventional treatment options for FS are physical therapy, nonsteroidal anti-inflammatory drugs, injection therapy, and arthroscopic capsular release, but adverse and limited effects continue to present problems. As a result, pharmacoacupuncture (PA) is getting attention as an alternative therapy for patients with FS. PA is a new form of acupuncture treatment in traditional Korean medicine (TKM) that is mainly used for musculoskeletal diseases. It has similarity and specificity compared to corticosteroid injection and hydrodilatation, making it a potential alternative injection therapy for FS. However, no systematic reviews investigating the utilization of PA for FS have been published. Therefore, this review aims to standardize the clinical use of PA for FS and validate its therapeutic effect. Methods: The protocol was registered in Prospero (CRD42023445708) on 18 July 2023. Until Aug. 31, 2023, seven electronic databases will be searched for randomized controlled trials of PA for FS. Authors will be contacted, and manual searches will also be performed. Two reviewers will independently screen and collect data from retrieved articles according to predefined criteria. The primary outcome will be pain intensity, and secondary outcomes will be effective rate, Constant-Murley Score, Shoulder Pain and Disability Index, range of motion, quality of life, and adverse events. Bias and quality of the included trials will be assessed using the Cochrane handbook's risk-of-bias tool for randomized trials. Meta analyses will be conducted using Review Manager V.5.3 software. GRADE will be used to evaluate the level of evidence for each outcome. Results: This systematic review and meta-analysis will be conducted following PRISMA statement. The results will be published in a peer-reviewed journal. Conclusion: This review will provide scientific evidence to support health insurance policy as well as the standardization of PA in clinical practice.

This study was conducted to evaluate the use of exogenous enzymes as a potential means of improving the ruminal digestion (i.e., degradability) of alfalfa hay and rice straw. Twenty six enzyme-additives were examined in terms of protein concentration and enzymic activities on model substrates. The exogenous enzymes contained ranges of endoglucanase, xylanase, ${\beta}$-glucanase, ${\alpha}$-amylase, and protease activities. Six of the enzyme additives were chosen for further investigation. The enzyme additives and a control without enzyme were applied to mature quality alfalfa hay substrate and subsequently incubated in rumen batch cultures. Five of the enzyme additives (CE2, CE13, CE14, CE19, and CE24) increased total gas production (GP) at 48 h of incubation compared to the control (p<0.05). The two additives (CE14 and CE24) having the greatest positive effects on alfalfa hay dry matter, neutral detergent fibre (NDF) and acid detergent fibre (ADF) degradability were further characterized for their ability to enhance degradation of low quality forages. The treatments CE14, CE24, a 50:50 combination of CE14 and CE24 (CE14+24), and control (no enzyme) were applied to mature alfalfa hay and rice straw. For alfalfa hay, application of the two enzyme additives, alone and in combination, increased GP compared to the control at 48 h fermentation (p<0.05), whereas only CE14 and CE14+24 treatments improved GP from rice straw (p<0.05). Rumen fluid volatile fatty acid concentrations throughout the incubation of rice straw were analyzed. Acetate concentration was slightly lower (p<0.05) for CE14${\times}$CE24 compared to the control, although individually, CE14 and CE24 acetate concentrations were not different from the control. Increases (p<0.05) in alfalfa hay NDF degradability measured at 12 and 48 h of incubation occurred only for CE14 (at 12 h) and for CE14+24 (at 12 and 48 h). Similarly, ADF degradability increased (p<0.05) with CE14 and CE14+24. As for rice straw, increased DM degradability was observed at 12 and 48 h of incubation for all enzyme treatments with an exception for CE14 at 12 h. The degradability of NDF was improved by all the enzyme treatments at either incubation time, while ADF degradability was only enhanced at 48 h. Overall, the enzymes led to enhanced digestion of mature alfalfa and there was evidence of improved digestibility of rice straw, an even lower quality forage.

Epilepsy is a brain disorder that affects millions of people worldwide and is usually managed using currently available antiepileptic drugs, which result in adverse effects and are ineffective in approximately 20-25% of patients. Thus, there is growing interest in the development of new antiepileptic drugs with fewer side effects. In a previous study, we showed that a Rehmannia glutinosa (RG) water extract has protective effects against electroshock- and pentylenetetrazol (PTZ)-induced seizures, with fewer side effects. In this study, the objective was to identify the RG components that are responsible for its anticonvulsant effects. Initially, a number of RG components (aucubin, acteoside, catalpol, and mannitol) were screened, and the anticonvulsant effects of different doses of catalpol, mannitol, and their combination on electroshock- and chemically (PTZ or strychnine)-induced seizures in mice, were further assessed. Gamma-aminobutyric acid (GABA) receptor binding assay and electroencephalography (EEG) analysis were conducted to identify the potential underlying drug mechanism. Additionally, treated mice were tested using open-field and rotarod tests. Catalpol, mannitol, and their combination increased threshold against electroshock-induced seizures, and decreased the percentage of seizure responses induced by PTZ, a GABA antagonist. GABA receptor binding assay results revealed that catalpol and mannitol are associated with GABA receptor activity, and EEG analysis provided evidence that catalpol and mannitol have anticonvulsant effects against PTZ-induced seizures. In summary, our results indicate that catalpol and mannitol have anticonvulsant properties, and may mediate the protective effects of RG against seizures.

Bronchial adenoma, firstly described by Muller[1882] had been reported on the subject stressed their benign nature prior to 1940`s, but these tumors including carcinoid tumor, mucoepidermoid carcinoma, adenoid cystic carcinoma, pleomorphic adenoma are now known to possess the various degree of malignant natures from benign course, low grade malignant potential to distant lymphatic or hematogenous metastasis or combination. Although histologically diffeerent, four varieties except carcinoid tumor which is a spectrum of neu-roendocrine tumor originating Kulchitsky cell of the bronchial epithelium and form the part of the APUD tumor spectrum, are morphologically and in many respects clinically similar to the corresponding tumor of the salivary gland is a specific varient of adenocarcinoma that occurs most commonly in the major and minor salivary gland and less frequently tra-cheobronchial tree, esophagus etc. To better understand the clinical characteristics and assess more precisely the malignat nature of bronchial adenoma, we studied 17 cases of bronchial adenoma, which had been experienced at the Department of Thoracic and Cardiovascular surgery of Catholic University Medical College from April 1977 to september 1991. Seventeen cases of bronchial adenoma consist of 2 carcinoid tumors, 6 adenoid cystic carcinomas, 8 mucoepidermoid carcinomas and one pleomorphic adenoma. There is a slight predominace of male patients[10/17] and the age of pt studied varied with a higher incidence occurring between the ages of 40 years and 60 years[mean age, 46.5 years]; the youngest being 15 years and oldest 69 years. Their leading complaints were hemoptysis[4], exertional dyspnea[8], fever & chilness [4], and symptoms mimicking the bronchial asthma[4]. Diagnosis was aided by the radiologic studies such as chest X-ray, polytomography, CT scan, brochography and bronchoscopy. The preferred locations of fumor were in the trachea[4], main stem bronchus[3], bronchus intermedius[3], bronchus of RUL[2], LUL[1], RLL[1], LLL[3] with no peripheral location. Modalities of treatments were single or combination of surgical resection, radiation therapy, chemotherapy. Complete resections were permitted in 12 cases with late recurrences of 4 cases ranging from 6 months to 10 years: pneumonectomy[4], lobectomy[4], bil-obectomy[2], sleeve resection[2]. Gross findings of resected specimens in 14 cases showed that 4 cases were polyp-like pedunculated mass[entirely intraluminal mass] with intact mucosa, 8 cases were broad-bas-ed sessile mass[predominatly intraluminal] and the main portions were located below the mucosa similar to tip of iceburg[predominantly extraluminal] in 2 cases. Follow-up information was availble in all 17 cases ; eight were alive without evidence of disese ranging from 1 month to 13 years. But seven cases died of the causes related to tumor[6 cases within 12 months, one case 10 years after pneumonectomy]. We concluded that 8 cases[47%] of 17 cases were metastasizing bronchial adenoma and precise survival rate cannot be answered by the scanty materials available for study.

Portland cement used as binding material in combination of ferrous iron for reductive dechlorination of chlorinated organics is already widely studied topic by several researchers. However there is no clear evidence about the component solely responsible in cement for trichloroethylene (TCE) dechlorination. Many researchers suspect that the ettringite, monosulfate phases associated with hydration of cement are responsible active agents for TCE dechlorination. This study deals with synthesizing different pure crystalline minerals like ettringite and monosulfate phases of cement hydration and check individual phase's TCE dechlorinating capacity in combination with ferrous iron. The results indicated that the synthesized minerals showed no reduction capacity for TCE. The findings in the present study is significant as it shows that ettringite and monosulfate phases which were suspected minerals by previous researchers for TCE dechlorination are not reactive. Hence it is suspected that some other mineral or mineral form in cement phase could be responsible for TCE degradation.
