Abstract
BACKGROUND Previous studies identified clinical and physiologic factors of idiopathic pulmonary fibrosis (IPF) that are related to an increased risk of mortality. But there are few studies about histologic and molecular approach. OBJECTIVE We investigated whether the C-reactive protein (CRP), fibroblastic foci, phosphorylated Smad2/3 (p-Smad2/3), tumor growth factor-beta (TGF-beta), TGF-beta receptor II (TbetaRII), and the polymorphism of the TGF-beta1 codon 10 are associated with the progression of IPF patients. DESIGN Eighty-six IPF patients who underwent surgical lung biopsies were examined. For each patient, clinical and physiologic parameters were investigated, and we performed immunohistochemical staining for p-Smad2/3 and TbetaRII, and genotyping of the TGF-beta1 codon 10 polymorphism. RESULTS Age at diagnosis, gender, symptom duration, and smoking status did not show a significant association. However, the amount of smoking (p = 0.002), severe reduction in the percentages of predicted forced vital capacity (p = 0.013) and diffusion lung capacity of carbon monoxide (p = 0.023), CRP (p = 0.009) at diagnosis, and fibroblastic foci (p = 0.026) were associated with a poor prognosis. Cellularity, fibrosis, expression level of p-Smad2/3 and TbetaRII, and genotype of the TGF-beta1 codon 10 polymorphism did not have a statistically significant association with the prognosis. CONCLUSION This study confirmed the amount of smoking, abrupt decrease in follow-up pulmonary function parameters, fibroblastic foci, and increased levels of CRP concentration at diagnosis were significantly associated with poor survival. Larger studies are required to confirm all prognostic factors including CRP.

Abstract
Ultrasonic sensors of 500 kHz frequency have been used to study the measuring of gas pressure in the range 1.33 × 10(3)-2.026 × 10(5) Pa. From the experimental data it was observed that amplitude of the transmitted ultrasound was dependent on gas pressure. The results confirm that by using appropriate instruments including sensors and electronic devices, pressure of the gas can be successfully measured by measuring the magnitude of the received signal. The proposed method is expected to be applied to develop as new vacuum pressure measurement instrument.

Abstract
BACKGROUND Peripheral venous pressure (PVP) is strongly correlated with central venous pressure (CVP) during various surgeries. Laparoscopic surgery in the Trendelenburg position with pneumoperitoneum typically increases CVP. To determine whether PVP convincingly reflects changes in CVP, we evaluated the correlation between PVP and CVP in patients undergoing laparoscopic colorectal surgery. METHODS Both CVP and PVP were measured simultaneously at predetermined time intervals during elective laparoscopic colorectal surgery in 42 patients without cardiac disease. The pairs of venous pressure measurements were analysed for correlation, and the Bland-Altman plots of repeated measures were used to evaluate the agreement between CVP and PVP. RESULTS A total of 420 data pairs were obtained. The overall mean CVP was 11.3 (sd 4.5) mm Hg, which was significantly lower than the measured PVP of mean 12.1 (4.5) mm Hg (P=0.005). There was a strong positive correlation between overall CVP and PVP (correlation coefficient=0.96, P<0.0001). The mean bias (PVP-CVP) corrected for repeated measurements using random-effects modelling was 0.9 mm Hg [95% confidence interval (CI) 0.54-1.19 mm Hg] with 95% limits of agreement of -1.2 mm Hg (95% CI -1.75 to -0.62 mm Hg) to 2.9 mm Hg (95% CI 2.35-3.48 mm Hg). CONCLUSIONS PVP displays a strong correlation and agreement with CVP under the increased intrathoracic pressure of pneumoperitoneum in the Trendelenburg position and may be used as an alternative to CVP in patients without cardiac disease undergoing laparoscopic colorectal surgery.

Abstract
BACKGROUND AND OBJECTIVE Lymphocyte-oriented kinase deficiency encoded by the serine/threonine kinase 10 (STK10) gene correlates with the intracellular adhesion molecule 1 (ICAM-1)/lymphocyte function associated antigen 1 (LFA-1) complex in aspirin hypersensitivity. This study investigated the association between single nucleotide polymorphisms (SNPs) of STK10 and aspirin-intolerant asthma (AIA). METHODS A total of 54 SNPs were genotyped in 163 AIA patients and 429 aspirin-tolerant asthma (ATA) controls. RESULTS Logistic regression revealed that a synonymous variant (rs2306961G>A) had the most significant association with AIA (P = .008 under the codominant model; P = .004 under the dominant model), suggesting that tissue-specific codon usage between Lys_TTT and Lys_CTT could play a role in regulating expression of STK10 in airway epithelium. Haplotype analysis revealed that 4 haplotypes, including STK10_BL4-ht1, which is unique to rs2306961G>A, were significantly associated with aspirin hypersensitivity in asthmatics (P < .05). CONCLUSIONS Although replications in independent cohorts and further functional evaluations are needed, our preliminary findings suggest that STK10 polymorphisms might be susceptible genetic markers of AIA and that gene expression could be mediated by tissue-specific codon usage.

Abstract
BACKGROUND As an E3 ubiquitin ligase and a molecular adaptor, Cbl-b controls the activation threshold of the antigen receptor and negatively regulates CD28 costimulation, functioning as an intrinsic mediator of T cell anergy that maintains tolerance. However, the role of Cbl-b in the airway immune response to aeroallergens is unclear. OBJECTIVE To determine the contribution of Cbl-b in tolerance to aeroallergens, we examined ovalbumin (OVA)-induced lung inflammation in Cbl-b-deficient mice. METHODS Cbl-b(-/-) mice and wild-type (WT) C57BL/6 mice were sensitized and challenged with OVA intranasally, a procedure normally tolerated by WT mice. We analysed lung histology, bronchoalveolar lavage fluid total cell counts and differential, cytokines and chemokines in the airway, and cytokine response by lymphocytes after re-stimulation by OVA antigen. RESULTS Compared with WT mice, OVA-challenged Cbl-b(-/-) mice showed significantly increased neutrophilic and eosinophilic infiltration in the lung and mucus hyperplasia. The serum levels of IgG2a and IgG1, but not IgE, were increased. The levels of inflammatory mediators IFN-γ, IL-10, IL-12, IL-13, IP-10, MCP-1, MIP-1α, eotaxin, and RANTES, but not IL-17A or IL-6, were elevated in the airway of Cbl-b(-/-) mice. Lymphocytes from Cbl-b(-/-) mice released increased amount of IFN-γ, IL-10, IL-13, and IP-10 in response to OVA re-stimulation. However, no significant changes were noted in the CD4(+) CD25(+) T regulatory cell populations in the lung tissues after OVA stimulation and there was no difference between WT and Cbl-b(-/-) mice. CONCLUSION These results demonstrate that Cbl-b deficiency leads to a breakdown of tolerance to OVA allergen in the murine airways, probably through increased activation of T effector cells, indicating that Cbl-b is a critical factor in maintaining lung homeostasis upon environmental exposure to aeroallergens.

Abstract
Heavy metal accumulation (Cu, Zn, Ni, and Pb) in common marine macroalga, Acrosorium uncinatum under nutrient (phosphate and nitrate) enriched (experiment 1) and starved (experiment 2) conditions over a short exposure period (12 h) were examined in this study. Control was maintained in seawater contained nutrient solution without addition of metals and in seawater alone for experiment 1 and 2, respectively. Among the four metals studied, the accumulation of Zn, Ni, and Pb was considerably lower than Cu. The accumulation factor for all metals varies greatly in different nutrient concentrations, but it increases as the exposure of metal concentration decreases in both the experiments. The results of the present findings established that this macroalga is an accumulator of metals Cu, Zn, Ni, and Pb and have the potential to accumulate these metals even in a short time exposure period (12 h). Even though metal accumulation by A. uncinatum largely depends on the available concentration in the medium, nutrients like phosphate and nitrate can affect the accumulation significantly.

Abstract
Effects of the Korean carcass-grading system on carcass traits and meat quality parameters for the longissimus dorsi (LD) and semimembranosus (SM) muscles were investigated for Hanwoo steer beef. High quality grade beef cuts had significantly higher intramuscular fat content than those of low quality grade beef cuts. To establish a guaranteed system of eating quality for Hanwoo steer beef, a palatability prediction model was developed. The model development approach used canonical discriminant analysis and multivariate regression to assess effects of muscle type, cooking method, and aging treatment on Hanwoo beef quality grade. The palatability prediction model can provide Korean consumers with detailed information about expected eating quality for an individual cut, as well as provide critical information to the industry for maintaining high-quality beef production. The model is a significant advance in grading compared with the traditional carcass grading system, which applies a single quality grade to an entire carcass.

Abstract
We show in bryophytes that abscisic acid (ABA) pretreatment of moss (Physcomitrella patens) cells confers desiccation tolerance. In angiosperms, both ABA and the transcriptional regulator ABSCISIC ACID INSENSITIVE 3 (ABI3) are required to protect the seed during desiccation. ABA was not able to protect moss cells in stable deletion lines of ABI3 (DeltaPpabi3). Hence, moss has the same functional link between ABA, ABI3, and the desiccation tolerance phenotype that is found in angiosperms. Furthermore, we identified 22 genes that were induced during ABA pretreatment in wild-type lines. When their expression was compared with that of DeltaPpabi3 during ABA pretreatment and immediately after desiccation, a new target of ABI3 action appears to be in the recovery period.

Abstract
Asarone is a molecule found in certain plants such as Acorus calamus, the root of which is used in traditional medicine to treat diabetes. We determined the molecular mechanism underlying the anti-diabetic activity of asarone. Treatment of asarone significantly inhibited the differentiation of 3T3-L1 preadipocytes through suppression of expression of the transcription factors, CCAAT/enhancer binding protein-alpha and peroxisome proliferator activated receptor-gamma, which activate adipogenesis. Intracellular triglyceride levels were reduced by asarone in a dose-dependent manner and asarone treatment stimulated the phosphorylation of hormone-sensitive lipase. Together, the present findings indicate that asarone inhibits adipogenesis by down-regulation of PPARgamma and C/EBPalpha and reduces lipid accumulation by stimulation of lipolysis through an increase in hormone-sensitive lipase activity.
