The purpose of this study was to investigate spirometric lung pattern, respiratory function and degree of fatigue by lung function tests and fatigue tests of 39 elderly people in a care facility aged 65 and over. The respiratory function tests were used to the Spirovit SP-1 and fatigue tests were used modified Piper fatigue scale(mPFS). Regarding the respiratory function, the FVC was 1.41±0.36ℓ, the FVC % predicted was 69.10±14.98%, the FEV1 was 1.02±0.31ℓ, the FEV1 % predicted was 63.27±16.05%, the FEV1/FVC was 72.77±13.40%, and the fatigue score was 5.83±1.09. As for the spirometric lung pattern, 19 patients had a restrictive pattern(48.7%), followed by 11 with a mixed pattern(28.2%), 5 with an obstructive pattern( 12.8%), and 4 with a normal pattern(10.3%). Regarding the respiratory function and fatigue by spirometric lung pattern, the FVC and the FVC % predicted of patients with a normal pattern or an obstructive pattern were greater than other groups at a statistically significant level. As for the FEV1, that of patients with a normal pattern was significantly higher than others, and for the FEV1 % predicted, that of patients with a normal pattern or a restrictive pattern was significantly higher(p<.001). Fatigue score by patients with a normal pattern was significantly less than patients of other patterns(p<.001). Therefore, pulmonary physical therapy is considered necessary to improve respiratory function and fatigue degradation of elderly in a facility.

Spatial distributions of alloying elements of an Fe-based amorphous ribbon with a nominal composition of Fe75C11Si2B8Cr4 were analyzed through the atom probe tomography method. The amorphous ribbon was prepared through the melt spinning method. The macroscopic amorphous natures were confirmed using an X-ray diffractometer (XRD) and a differential scanning calorimeter (DSC). Atom Probe (Cameca LEAP 3000X HR) analyses were carried out in pulsed voltage mode at a specimen base temperature of about 60 K, a pulse to base voltage ratio of 15 %, and a pulse frequency of 200 kHz. The target detection rate was set to 5 ions per 1000 pulses. Based on a statistical analyses of the data obtained from the volume of 59×59×33nm3, homogeneous distributions of alloying elements in nano-scales were concluded. Even with high carbon and strong carbide forming element contents, nano-scale segregation zones of alloying elements were not detected within the Fe-based amorphous ribbon. However, the existence of small sub-nanometer scale clusters due to short range ordering cannot be completely excluded.

Alpha-tocopherol as an antioxidant acts in preservation of chilled semen by preserving cell membrane damage from lipid peroxidation. Optimum concentrations of α-tocopherol in egg yolk-citrate (EYC) extender need to be studied in crossbred bull’s semen. Different concentrations of α-tocopherol viz. 0, 1, 2, 4 and 6mg per ml of extender were used. Semen was collected once a week from four bulls used to regular collection, aged 4 to 7 years, weighing 320 to 450 kg, and with body condition score 4 to 4.5 and scrotal circumference 23 to 32 cm. Semen was evaluated routinely and sperm morphology was viewed under light microscope at ×1,000 magnification after fixing with buffered formal saline. Over 90% had normal head, acrosome, mid-piece and tail. Semen was diluted with egg-yolk-citrate extender to produce 15×106 spermatozoa/ml and 0, 1, 2, 4 and 6 mg/ml α-tocopherol were added. The semens amples were kept at 8℃. Sperm motility and viability were examined daily up to 5 days under light microscopy at ×200 magnification. Sperm viability was acceptable (≥40%) up to the 4th day with all concentrations of α-tocopherol and up to the 5th day with 2 mg/ml α-tocopherol. Sperm motility was acceptable (≥40%) up to the 3rd day irrespective of α-tocopherol concentration, and up to the 4th day with 2 mg/ml α-tocopherol. It is suggested that the lifespan of chilled semen may be extended up to 4 days by adding 2mg/ml α-tocopherol.

This study aims to examine the effects of taping of the ankle joint on the static and dynamic balance and gait ability of stroke patients. Twenty-six stroke patients receiving physical therapy at a hospital located in Gyeonggi-do were divided equally into a group that had taping in physical therapy and an ordinary physical therapy group. They exercised for 30 minutes each, 3 times per week for 8 weeks from June to August 2011. Romberg’s eye open and eye closed tests, limits of stability(LOS), forward and back test, timed up and go test(TUG) and 10-meter gait velocity test were performed to evaluate static balance, dynamic balance, and gait ability, respectively, prior to and 8 weeks after the intervention. Differences within each group in relation to the lapse of time were compared by a paired t-test. Differences between the two groups were compared by an independent t-test. Regarding comparison of differences within each group, all tests resulted in significant changes in both groups after the intervention (p<.05). Comparison of differences between the two groups showed that taping in the physical therapy group had significantly better test results than the ordinary physical therapy group in all measured items(p<.05). The after effects of ankle taping on stroke patients are more efficient and effective than ordinary physical therapy alone in improving balance and gait ability.

Probiotics, enzymes, organic acids, oligosaccharides, antioxidants, and other functional materials are actively being explored as alternatives to antibiotics. Probiotics include live beneficial microorganisms that colonize the intestinal tract and competitively inhibit attachment and growth of harmful microbes. Probiotics also increase feed efficiency by assisting in nutrient absorption and digestion. The current study was conducted in order to evaluate the effect of a new probiotic, CS-A, as a dietary supplement of a fermented product on growth performance, feed intake, and feed conversion efficiency in broiler chickens, and to evaluate its value as an alternative for antibiotics used as a feed additive. Antibacterial and anti-inflammatory effects of CS-A were investigated in vitro and the in vivo effects of a constant concentration of supplemented CS-A on growth rate and feed efficiency were evaluated. In addition, the safety of CS-A was assessed by examination of common symptoms and mortality. Determination of minimal inhibitory concentration revealed an excellent antibacterial effect of CS-A. Cytotoxicity was low and anti-inflammatory effects were achieved at the effective concentration of CS-A. Supplementation with 0.1% CS-A resulted in a feed efficiency score of 1.84 in broilers, compared to 2.00 in the control group. There were no adverse clinical findings, necropsy findings, hematology, and altered serum biochemistry parameters, and no mortality. Thus, it is concluded that CS-A is safe and effective as a feed additive.

An overview of the North Ecliptic Pole (NEP) deep multi-wavelength survey covering from X-ray to radio wavelengths is presented. The main science objective of this multi-wavelength project is to unveil the star-formation and AGN activities obscured by dust in the violent epoch of the Universe (z=0.5-2), when the star formation and black-hole evolution activities were much stronger than the present. The NEP deep survey with AKARI/IRC consists of two survey projects: shallow wide (8.2 sq. deg, NEP-Wide) and the deep one (0.6 sq. deg, NEP-Deep). The NEP-Deep provides us with a 15 μm or 18 μm selected sample of several thousands of galaxies, the largest sample ever made at these wavelengths. A continuous filter coverage at mid-IR wavelengths (7, 9, 11, 15, 18, and 24 μ m ) is unique and vital to diagnose the contribution from starbursts and AGNs in the galaxies at the violent epoch. The recent updates of the ancillary data are also provided: optical/near-IR magnitudes (Subaru, CFHT), X-ray (Chandra), FUV/NUV (GALEX), radio (WSRT, GMRT), optical spectra (Keck/DEIMOS etc.), Subaru/FMOS, Herschel/SPIRE, and JCMT/SCUBA-2.

Interferon-tau (IFNT) is regarded, generally, to be the conceptus protein that signals maternal recognition of pregnancy in ruminants. Although the discovery was made over two decades ago, the molecular mechanisms that regulate IFNT expression are not well understood. Previous studies demonstrated that transcription factors, caudal-related homeobox- 2 (CDX2), JUN, ETS2 and a transcriptional coactivator CREB binding protein (CREBBP) positively influenced IFNT gene expression, while OCT4 may exhibit negative regulation. We and others have observed that both CDX2 and OCT4 coexist during early stages of conceptus elongation but as development proceeds, OCT4 expression diminishes. The objective of this study was to evaluate the stimulatory and inhibitory effects of CDX2 and OCT4, respectively, on IFNT gene transcription when evaluated with other transcription factors. Human choriocarcinoma JEG3 cells were co-transfected with an ovine IFNT (-654 base pair)-luciferase reporter (-654-oIFNT-Luc) construct and several transcription factor expression plasmids. When the reporter construct was co-transfected with either CDX2, ETS2 or CJUN, transcription of -654-oIFNT-Luc increased about two-fold compared to -654-oIFNT-Luc alone. When -654-oIFNT-Luc was co-transfected with both c-jun and Ets-2, activity of -654-oIFNT-Luc was increased about four-fold; cotransfection with JUN, ETS2 and CDX2 increased -654-oIFNT-Luc expression 12X, indicating that the stimulatory activity of the transcription factors was additive. OCT4, when cotransfected with -654-oIFNT-Luc, reduced expression of the later about 40% when compared to -654-oIFNT-Luc alone. When co-transfected with JUN and/or ETS2, OCT4 abolished the stimulatory effect of these transcription factors. OCT4 also inhibited the stimulatory activity of CDX2 alone, but not when CDX2 was combined with JUN and/or ETS2. Therefore, when combined with the other transcription factors, CDX2 over the transcriptional inhibitory activity of OCT4. Conversely, when cells were transfected initially with OCT4 (0h) followed by transfection with CDX2, ETS2 and JUN 24 h later, -654-oIFNT-Luc expression was reduced to control (-654-oIFNT-Luc, alone) levels. Not surprisingly, 12S E1A, an inhibitor of transcriptional coactivator CREBBP, reduced stimulation of -654- oIFNT-Luc expression by CDX2, ETS2 and JUN, in combination, by about 40%, indicating that proper transcription complex formation is required for maximum expression. In conclusion, it is suggested that prior to conceptus elongation, pre-existing OCT4 may inhibit IFNT expression, but as elongation proceeds, IFNT expression increases, resulting from incremental increases in CDX2 expression, diminished OCT4 expression, and possibly proper transcription factor complex formation.

The aim of this study was to investigate the correlation among bone mineral density(BMD), body composition and body circumference on 20's college women in Hwaseong. A total of 86 subjects were measured with BMD and body composition and body circumference. To evaluate the correlation between BMD and body composition, bone density and body weight, body mass index(BMI), lean body mass, muscle mass, fat mass and body fat mass were compared. The results of this study, weight was considered the strong correlation with BMD than the height and BMI seems to be greater significance rather than the lumbar spine and femur BMD. In addition, the relationship between body composition and BMD, lean body mass, muscle mass, body fat mass were the most relevant factors and BMD. The relationship between BMD and body circumference that have been difficult because of not enough previous studies but somewhat the study showed that association.

Experiments were conducted in order to assess the healing effect of bee venom (BV) cream on full-thickness skin wounds in rabbits. BV cream was compared with silver sulfadiazine (SS) as a topical medicament against a control on experimentally created full-thickness wounds. Two wounds measuring 2 × 2 cm were created bilaterally (four wounds/rabbit) on the dorsolateral aspect of the trunk of seven New Zealand white rabbits. Wound treatments were evenly distributed on four sites, using a Latin square design. The contact layer of wounds was treated with physiological saline (control), SS cream, and BV cream over a period of 28 days. Assessment of wound healing was based on scab hardness, wound exudates, wound area, unepithelialized granulation tissue, and histopathological findings. Topical application of BV and SS creams to wounds resulted in reduced inflammation, debridement of necrotic tissue, and promoted granulation and epithelialization. Wound healing was faster, with statistical significance in BV and SS treatments, compared to the control (P<0.05). Treatment with BV evoked an anti-inflammation effect in a rabbit model. BV cream produced a wound healing effect similar to that of commercially available SS cream. Anti-inflammation effect as a topical treatment with BV cream appears to be better than that with SS cream. These results suggest that topical application of BV cream may be an alternative treatment for full-thickness skin wounds.

A study was conducted on four crossbred bulls, used as artificial insemination (AI) sires, to correlate their semen quality with their non return rate (NRR). Semen was collected once a week via an artificial vagina, diluted in egg yolk-citrate and maintained at for three days. It was evaluated for sperm motility, viability, morphology immediately after collection and was examined daily for sperm motility, viability and morphology of acrosome, mid piece and tail for a total of three days. A total of 2016 cows were inseminated by two AI technicians. The proportions of sperm with normal heads were 83.4% (63.7~91.7%), the proportion of spermatozoa exhibiting normal morphology (acrosome, mid piece and tail), motility and viability were 89.2% (82.3~92.0%), 71.3% (61.7~75.0%) and 76.7% (65.7~85.0%), respectively in fresh ejaculates. Sperm motility and sperm viability was significantly ( <0.05) lower in Holstein-Friesian Local bull than in other bulls during all three days of storage. The overall NRR for four bulls was 82.7% (72.9-87.5%). Bulls with higher sperm motility, viability and normal morphology of spermatozoa of individual bull had significantly (each <0.05) higher NRR. The highest ( <0.01) NRR (87.5%) was observed in a Red Chittagong bull whose semen qualities were significantly ( <0.05) higher than Holstein-Friesian Local bull (NNR 72.9%). The results of the present study concluded that NRR at 56 days post AI is related to parameters of semen quality. Therefore, semen evaluation may allow the discarding of bulls with poor fertility in an AI program.

This study demonstrated that hyaluronic acid (HA) accelerated peripheral nerve regeneration after crush injury to the common peroneal nerve in an experimental rabbit model. Ten male New Zealand White rabbits, weighing 1.8 to 2.0 kg, were used in this study. After creating the nerve crush model in every right leg, rabbits were divided into two groups. Animals in group A received application of HA into the area surrounding the crushed nerve, and group B was the sham control. Electrophysiological assessment was performed every week. After 10 weeks, nerve histological examination, muscle weight and muscle histology were used to evaluate regeneration of the injured common peroneal nerve. No differences in electrophysiological assessment were observed between the two groups. In peripheral nerve histology, myelinated nerve fibers were observed more frequently and less connective tissue was observed in the crushed nerve of group A. Fewer muscle degenerative changes, such as fibrosis, atrophy, and centrally located myonuclei, were detected in group A than in group B. In conclusion, HA could become a potential neuroprotective agent for improvement of peripheral nerve regeneration after crush injury.
