This experiment was carried out to compare the effects of six different plant protein sources such as soybean meal, extruded full-fat soybean, canola meal, rapeseed meal, cottonseed meal and perilla meal as a sole protein source of diets on growth performance and amino acid bioavailabilities in growing-finishing pigs. A total of 54 pigs with average 25 kg of body weight were used as experimental subjects for a 65-d feeding trial. Digestion trial was carried out with seven ileal-cannulated pigs. The most rapid rate of weight gain was observed in pigs fed soybean meal and full-fat soybean, the moderate one in pigs fed canola meal and cottonseed meal and the least one in pigs fed rapeseed meal and perilla meal (p<0.005). Feed efficiency was better for groups fed soybean meal and full-fat soybean than other protein meals (p<0.05). The apparent ileal digestibilities of essential amino acids of soybean meal and full-fat soybean (82.5% and 81.6%) were significantly (p<0.05) higher than those of other protein sources (61.2 to 69.4%). Regardless of protein sources, the apparent ileal digestibility of arginine was highest, whereas that of histidine was lowest among essential amino acids. Proline had the lowest digestibility among non-essential amino acids. True amino acid digestibilities tended to be higher than apparent amino acid digestibilities. The differences between true and apparent ileal digestibilities were greater in canola meal, rapeseed meal or cottonseed meal than other protein sources. The differences was greatest in praline except for cottonseed meal. The fecal digestibility appeared to be higher than the ileal digestibility. The differences between fecal and ileal digestibilities were greater in canola meal, rapeseed meal, cottonseed meal and perilla meal than in soybean meal and full-fat soybean. In general, praline was the most disappeared amino acid in the hind gut, while the net synthesis of lysine in the large intestine was observed in all protein sources except perilla meal. It is appropriate that swine feeds should be formulated based on true ileal amino acid digestibility of protein sources for pig's normal growth.

To elucidate the effect of microsphere coinjection on the administration of oligodeoxynucleotides (ODN), we have investigated biodistribution of ［S-35］-labeled antisense ODN targeted to cAMP-dependent protein kinase (PKA) RI-$\alpha$ subunit in nude mice xenografted with WiDr (human colon cancer, ATCC CCL218). The strategy of using microsphere has been proposed for cancer treatment as a carrier of therapeutic ODN so that it could offer an advantage with respect to maintaining constant ODN levels in blood and obtaining higher therapeutic ODN concentration at tumor sites. Comparative biodistribution studies were performed in nude mice (female, 20 g of body weight, n = 4-6) xenografted with WiDr cancer cells, when 0.1 $\mu$Ci (specific activity, 2.94 mCi/$\mu$mole) of ［S-35］-labeled RI-$\alpha$ antisense ODN was injected alone or with microsphere (PLG-18, polylactic copolymer with cationic surfactant DDAB18). Peak tumor uptake of ［S-35］-labeled ODN was significantly increased from 17.7% (at 6 h) of injected dose per gram of tissue (ID/g) to 42.5% (at 24 h) ID/g when microsphere was coinjected with ODN. The different biodistribution in the kidney accumulation (e.g., 100.2% ID/g for ODN alone and 54.9%/ID/g for microshpere coinjection) may contribute to higher blood concentration (e.g., 21.5%ID/$m\ell$ for ODN alone and 37.5%ID/$m\ell$ for microsphere coinjection) of radiolabeled ODN. Of importance is the fact that the whole body retention of radioactivity increased with microsphere coinjection from 50.8%ID/g to 68.0%ID/g after 24-h of injection. This decreased kidney accumulation and increased whole body retention of ［S-35］-labeled ODN resulted in a significant improvement of ODN targeting to the tumor site. In conclusion, the coinjection of microsphere appears to be an important carrier system in vehiculation of antisense oligonucleotide to the tumor tissue in vivo.

Purpose: The purpose of this study was to evaluate the diagnostic accuracy of X-rays in patients with acute traumatic vertebral fractures visiting the emergency department and to analyze the diagnostic value of X-rays for each spine level. Methods: We retrospectively analyzed basal characteristics by reviewing medical records of 363 patients with adult traumatic vertebral fractures, admitted to the emergency center from March 1, 2014 to February 28, 2017. We analyzed spine X-rays and magnetic resonance imaging (MRI) scans to determine distribution according to the vertebral level, and we evaluated the efficacy of X-rays by comparing discrepancies between X-rays and MRI scans. Results: For a total of 363 patients, the mean age was 56.65 (20-93) and 214 (59%) were males. On the basis of X-rays, 67 cases (15.1%) were of the cervical spine, 133 cases (30.0%) were of the thoracic spine, and 243 cases (54.9%) were of the lumbar spine. In particular, the thoracolumbar region (T11-L2) was the most common, with 260 cases (58.7%). In X-rays, fractures were the least in the upper thoracic region (T1-T3), whereas MRI scans revealed fairly uniform distribution across the thoracic spine. Sensitivity of X-rays was lowest in the upper thoracic spine and specificity was almost always greater than 98%, except for 94.7% in L1. Positive predictive value was lower in the mid-thoracic region (T4-T9) and negative predictive value was slightly lower in C6, T2, and T3 than at other sites. Diagnostic accuracy of X-rays by vertebral body, transverse process, and spinous process according to fractured vertebral structures was significantly different according to vertebral level. Conclusions: Diagnostic accuracy of X-rays was lower in the upper thoracic region than in other parts. Further studies are needed to identify better methods for diagnosis considering cost and neurological prognosis.

The antioxidant and digestive enzyme inhibitory effects of Eisenia bicyclis extracted by various extraction methods (RE, reflux extraction; SE, ultrasonification extraction; AE, autoclave extraction; LE, low-temperature high-pressure extraction) were investigated. The extraction yield (55.21%) and the laminarin (39.03%), fucoidan (24.75%), total polyphenol (115.68 mg GAE/g) and flavonoid (36.67 mg RHE/g) contents of AE were higher than those in other methods. The DPPH radical (86.60%, 500 mg%), ABTS radical (58.56%, 25 mg%), nitrite (86.38%, 100 mg%) scavenging activities of the Eisenia bicyclis extracted by AE were higher than those of Eisenia bicyclis extracted by other methods. The ABTS radical and nitrite scavenging activities were above 98% in all tested Eisenia bicyclis extracts and these activities were dependent on its concentration. The inhibitory effects of AE against amylase (50 mg%) and ${\alpha}$-glucosidase (5 mg%) were 64.76% and 86.71%, respectively. The AE showed the best inhibitory effect of Eisenia bicyclis extracts (50 mg%) against trypsin (24.37%) and ${\alpha}$-chymotrypsin (49.05%), respectively. These results suggest that Eisenia bicyclis extracted by AE can be used as a bioactive and functional material in the food industry.

The composition of four rice protein groups is greatly affected by the extraction conditions. The extraction amounts of albumins and glubulines primarily depended on the temperature rather than the method of extraction. The total amount of glutelins, the major components of rice storage proteins, could be extracted by a successive extraction processes, extraction with 0.5% SDS-0.1M borate buffer(pH 8.3) followed by extraction with 0.5% SDS-0.6% ${\beta}-mercaptoethanol-0.1M$ borate buffer(pH 8.3). The extracted amounts of glutelin with these solvents were 54.1 and 45% respectively. The further purification of SDS soluble glutelins was achieved by Sephadex G-150 gel column chromatography. The molecular weight of the components in four protein groups has been estimated by SDS-polyacrylamide gel electrophoresis with or without ${\beta}-mercaptoethanol.$ The comparison of albumins and globulins by starch gel electrophoresis at pH 3.1 permitted us to identify seven rice varieties. However, at pH 8.95, the specific bands for Japonica type rice varieties were observed.

Background: Metabolic disorders, including type II diabetes and obesity, present major health risks in industrialized countries. AMP-activated protein kinase (AMPK) has become the focus of a great deal of attention as a novel therapeutic target for the treatment of metabolic syndromes. In this study, we evaluated whether dietary aloe could reduce obesity-induced inflammation and adipogenesis. Methods: Male C57BL/6 obese mice fed a high-fat diet for 54 days received a supplement of aloe formula (PAG, ALS, Aloe QDM, and Aloe QDM complex) or pioglitazone (PGZ) and were compared with unsupplemented controls (high-fat diet; HFD) or mice fed a regular diet (RD). RT-PCR and western blot analysis were used to quantify the expression of obesity-induced inflammation. Results: Aloe QDM complex downregulated fat size through suppressed expression of scavenger receptors on adipose tissue macrophages (ATMs) compared with HFD. Both white adipose tissue (WATs) and muscle exhibited increased AMPK activation through aloe supplementation, and in particular, the Aloe QDM complex. Obesity-induced inflammatory cytokines (IL-$1{\beta}$ and -6) and $HIF1{\alpha}$ mRNA and protein were decreased markedly, as was macrophage infiltration by the Aloe QDM complex. Further, the Aloe QDM complex decreased the translocation of NF-${\kappa}B$ p65 from the cytosol in the WAT. Conclusion: Dietary aloe formula reduced obesity-induced inflammatory responses by activation of AMPK in muscle and suppression of proinflammatory cytokines in the WAT. Additionally, the expression of scavenger receptors in the ATM and activation of AMPK in WAT led to reduction in the percent of body fat. Thus, we suggest that the effect of the Aloe QDM complex in the WAT and muscle are related to activation of AMPK and its use as a nutritional intervention against T2D and obesity-related inflammation.

Objective: Lung segmentation using volumetric quantitative computed tomography (CT) analysis may help predict outcomes of patients with coronavirus disease (COVID-19). The aim of this study was to investigate the relationship between CT volumetric quantitative analysis and prognosis in patients with COVID-19. Materials and Methods: CT images from patients diagnosed with COVID-19 from February 18 to April 15, 2020 were retrospectively analyzed. CT with a negative finding, failure of quantitative analysis, or poor image quality was excluded. CT volumetric quantitative analysis was performed by automated volumetric methods. Patients were stratified into two risk groups according to CURB-65: mild (score of 0-1) and severe (2-5) pneumonia. Outcomes were evaluated according to the critical event-free survival (CEFS). The critical events were defined as mechanical ventilator care, ICU admission, or death. Multivariable Cox proportional hazards analyses were used to evaluate the relationship between the variables and prognosis. Results: Eighty-two patients (mean age, 63.1 ± 14.5 years; 42 females) were included. In the total cohort, male sex (hazard ratio [HR], 9.264; 95% confidence interval [CI], 2.021-42.457; p = 0.004), C-reactive protein (CRP) (HR, 1.080 per mg/dL; 95% CI, 1.010-1.156; p = 0.025), and COVID-affected lung proportion (CALP) (HR, 1.067 per percentage; 95% CI, 1.033-1.101; p < 0.001) were significantly associated with CEFS. CRP (HR, 1.164 per mg/dL; 95% CI, 1.006-1.347; p = 0.041) was independently associated with CEFS in the mild pneumonia group (n = 54). Normally aerated lung proportion (NALP) (HR, 0.872 per percentage; 95% CI, 0.794-0.957; p = 0.004) and NALP volume (NALPV) (HR, 1.002 per mL; 95% CI, 1.000-1.004; p = 0.019) were associated with a lower risk of critical events in the severe pneumonia group (n = 28). Conclusion: CRP in the mild pneumonia group; NALP and NALPV in the severe pneumonia group; and sex, CRP, and CALP in the total cohort were independently associated with CEFS in patients with COVID-19.
