Abstract
BACKGROUND Liposomes containing docosahexaenoic acid (DHA) and phosphatidylserine were claimed to inhibit osteoclast formation and bone resorption in the inflammatory status. Herein, we proposed that an apoptotic mimicry (SQ liposome) prepared from squid-skin phospholipids can explore the suppressive osteoclastogenesis. METHODS The intermolecular fatty-acid composition in the phospholipid of squid-skin extract was analyzed by GC-FID. The SQ liposome structure was characterized by size distribution and zeta potential (ζ). RAW 264.7 cell is used to study the effect of SQ liposomes on osteoclast differentiation. Secretion of prostaglandin E2 (PGE2) and transforming growth factor-β (TGF-β) from RAW 264.7 cells were assayed. Antiosteoclastogenesis effects were performed via the tartrate-resistant acid phosphatase (TRAP)-positive multinucleated cell (MNC) counting, bone resorption pit assay, and TRAP activity analysis. The specific gene expressions related to antiosteoclastogenesis were also detected. RESULTS An apoptotic mimicry through the use of a single-layer liposome (SQ liposome) with phosphatidylserine exposure contains DHA (28.7%) and eicosapentaenoic acid (EPA, 11.8%). Co-treatment with receptor activator of nuclear factor kappa B ligand (RANKL)/macrophage colony-stimulating factor induced RAW 264.7-cell differentiation into mature osteoclasts, thus enhancing PGE2 and TGF-β secretion. However, cotreatment with 1 mg/mL of SQ liposome restored (p < 0.05) the cell viabilities under the RANKL stress. Increased PGE2 levels was downregulated (p < 0.05) in cotreatments with 0.11 and 0.33 mg/mL of SQ liposome, but on the TGF-β levels were not (p > 0.05) influenced in SQ liposome cotreatments. Cotreatments with 0.33-1 mg/mL of SQ liposome suppressed (p < 0.05) the osteoclast maturation (such as decreased MNCs and bone pit formation), inhibited TRAP activities, and downregulated the osteoclastogenesis-related gene expressions. CONCLUSION In summary, current data support that a possible prevention of our prepared SQ liposomes which are rich in DHA and EPA on bone loss is through the suppression of osteoclastogenesis. Moreover, based on the results from this study an in vivo study warrants a further investigation.

Abstract
BACKGROUND/PURPOSE Herpes simplex virus type 1 (HSV-1) is the pathogenic agent of human diseases, including gingivostomatitis and herpes labialis. The anti-viral activities of the tea polyphenol, epigallocatechin-3-gallate (EGCG), have been demonstrated. This study examined the combined effects of EGCG and the antiviral drug, acyclovir (ACV), on infection of HSV-1 in oral epithelial cells. METHODS Cell viability was examined using 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyltetrazolium bromide. Viral yields were determined using the plaque assay. Viral proteins were detected using Western blotting analysis or confocal laser scanning microscopy. Viral DNA was detected using the real-time polymerase chain reaction. RESULTS Cytotoxic effects of HSV-1 on the viability of oral epithelial cells were evidently reduced in the presence of EGCG (25 μg/ml) or/and ACV (50 μg/ml). Viral yields were also significantly reduced by treatment of cells with EGCG or/and ACV. Expression of viral immediate early protein, infected cell protein 0 (ICP0), was greatly inhibited when cells were treated with EGCG. Combined effects of EGCG and ACV were more evident for the expression of viral thymidine kinase, ICP5 and glycoprotein D. EGCG, but not ACV, significantly reduced the levels of viral particles and viral DNA during viral entry phase. However, at 20 h post infection, the intracellular viral DNA was evidently reduced in HSV-1 infected cells treated with EGCG and ACV. Moreover, the stimulatory effects of HSV-1 on phosphorylation of c-Jun N-terminal kinase could be reduced by ACV. CONCLUSION The results demonstrated the additive effects of EGCG and ACV on HSV-1 infection in oral epithelial cells.

Abstract
Objective: To investigate the mechanism of maggot debridement therapy (MDT) in promoting wound angiogenesis in patients with diabetic foot ulcer (DFU). Methods: (1) From June 2018 to June 2019, the patients admitted to Nanjing Junxie Hospital who met the inclusion criteria were recruited, including 12 DFU patients given MDT for three days [6 males and 6 females, aged (56±12) years] and 12 acute trauma patients without diabetes mellitus [6 males and 6 females, aged (53±10) years], who were enrolled into DFU group and non-diabetic trauma group respectively. Before and after application of MDT, the wound characteristics of patients in DFU group were observed and the wound tissue samples were taken. The wound tissue in non-diabetic trauma group was taken at patient's first visit before debridement. The expression of angiogenesis marker CD31 in the wound tissue of patients in DFU group was detected by immunohistochemistry before and after application of MDT. Western blotting and real-time fluorescent quantitative reverse transcription polymerase chain reaction (RT-PCR) were used respectively to detect the protein and mRNA expressions of fatty acid synthase (FAS) in wound tissue of patients in DFU group before and after application of MDT and in non-diabetic trauma group before debridement. (2) Human umbilical vein endothelial cells (HUVECs) were cultured in endothelial cell culture medium containing 10% fetal bovine serum. The 3rd to 6th passages of cells in logarithmic growth phase were used in the following experiments. Excretions/secretions (ES) were extracted from 3-day-old sterile Lucilia sericata larvae for subsequent experiments. Three batches of cells were divided into phosphate buffer solution (PBS) control group, high glucose alone group, high glucose+ 5 μg/mL maggot ES group, and high glucose+ 10 μg/mL maggot ES group, which were treated with PBS, glucose in final molarity concentration of 20 mmol/L, glucose in final molarity concentration of 20 mmol/L+ maggot ES in final mass concentration of 5 μg/mL, and glucose in final molarity concentration of 20 mmol/L+ maggot ES in final mass concentration of 10 μg/mL respectively. The total volume of reagents in each group was the same. After 48 hours of culture, Western blotting, real-time fluorescent quantitative RT-PCR and immunofluorescence method were used to detect the protein and mRNA expressions of FAS in each batch of cells and the expression and localization of FAS protein in cells respectively. The number of samples for mRNA expression was 3. (3) Two batches of cells were divided into small interference RNA (siRNA) alone group, siRNA control+ maggot ES group and siRNA-FAS+ maggot ES group, which were transfected with 100 μmol/L (final molarity concentration) insignificant control siRNA, insignificant control siRNA, and siRNA-FAS for 4-6 h respectively, and then they were routinely cultured for 24 h with PBS added, maggot ES in final mass concentration of 10 μg/mL, and maggot ES in final mass concentration of 10 μg/mL respectively. The total volume of reagents in each group was the same. One batch of cells was used for scratch test, the scratch width was observed at 24 hour after scratching to detect the cell migration ability; one batch of cells was subjected to tube forming experiment, and the formation of cell tubules was observed after 24 hours of culture. The number of samples was 3 in scratch test and tube forming experiments. Data were statistically analyzed with t test, one-way analysis of variance, least significant difference test, analysis of variance for repeated measurement, and Bonferroni method. Results: (1) Compared with those before application of MDT, fresh granulation tissue significantly increased and necrotic tissue decreased obviously in wound, and the expression of CD31 significantly increased in wound tissue of patients in DFU group after application of MDT. The expression of FAS protein in wound tissue of patients in DFU group before application of MDT was significantly lower than that in non-diabetic trauma group before debridement, and the expression of FAS protein in wound tissue of patients in DFU group after application of MDT was significantly higher than that before application of MDT. The expression of FAS mRNA in wound tissue of patients in DFU group before application of MDT was 1.00±0.17, which was significantly less than 3.87±1.02 in non-diabetic trauma group before debridement (t=9.808, P<0.01). The expression of FAS mRNA in wound tissue of patients in DFU group after application of MDT was 1.85±0.31, which was significantly higher than that before application of MDT (t=-10.853, P<0.01). (2) After 48 hours of culture, Western blotting detection showed that the expression of FAS protein in cells in high glucose alone group was significantly less than that in PBS control group, and the expressions of FAS protein in cells in high glucose+ 5 μg/mL maggot ES group and high glucose+ 10 μg/mL maggot ES group were significantly higher than the expression in high glucose alone group. Real-time fluorescent quantitative RT-PCR determination showed that the expression of FAS mRNA in cells in high glucose alone group was 0.392±0.073, which was significantly lower than 1.000±0.085 in PBS control group (P<0.01); there was statistically significant difference between the expression of FAS mRNA in cells in high glucose+ 5 μg/mL maggot ES group (0.561±0.047) and that in high glucose+ 10 μg/mL maggot ES group (0.687±0.013) (P<0.05), both of which were significantly higher than the expression in high glucose alone group (P<0.01). The results of immunofluorescence detection showed that FAS protein was mainly located in the cytoplasm of cells in each group, and its expression was similar to that detected by Western blotting. (3) At 24 hour after scratch, the uncured widths of cell scratch in siRNA control+ maggot ES group and siRNA-FAS+ maggot ES group were significantly narrower than the uncured width in siRNA alone control group (P<0.01), and the uncured width of cell scratch in siRNA-FAS+ maggot ES group was significantly wider than that in siRNA control+ maggot ES group (P<0.01). After 24 hours of culture, the numbers of tubules in siRNA+ maggot ES group and siRNA-FAS+ maggot ES group were significantly more than the number in siRNA alone control group (P<0.05 or P<0.01), and the number of tubules in siRNA-FAS+ maggot ES group was obviously less than that in siRNA control+ maggot ES group (P<0.05). Conclusions: MDT up-regulates the expression of FAS through maggot ES, which promotes the activity of vascular endothelial cells, thus promoting the wound angiogenesis in patients with DFU.

Abstract
Background Glioblastoma (GBM) is the most lethal brain tumor characterized by high morbidity and limited treatment options. Tumor malignancy is usually associated with the epigenetic marks, which coordinate gene expression to ascertain relevant phenotypes. One of such marks is m6A modification of RNA, whose functional effects are dependent on the YTH family m6A reader proteins. Methods and results In this study, we investigated the expression of five
YTH family proteins in different GBM microarray datasets from the Oncomine
database, and identified YTHDF1 as the most highly overexpressed member of this
family in GBM. By performing the knockdown of YTHDF1 in a GBM cell line, we
found that it positively regulates proliferation, chemoresistance and cancer
stem cell-like properties. Musashi-1 (MSI1) is a postranscriptional gene
expression regulator associated with high oncogenicity in GBM. By knocking down
and overexpressing MSI1, we found that it positively regulates YTHDF1
expression. The inhibitory effects
imposed on the processes of proliferation and migration by YTHDF1 knockdown
were shown to be partially rescued by concomitant overexpression of MSI1. MSI1
and YTHDF1 were shown to be positively correlated in clinical glioma samples,
and their concomitant upregulation was associated with decreased survival of
glioma patients. We identified the direct regulation of YTHDF1 by MSI1. Conclusions Given the fact that both proteins are master
regulators of gene expression, and both of them are unfavorable factors in GBM,
we suggest that in any future studies aimed to uncover the prognostic value and
therapy potential, these two proteins should be considered together.

Abstract
Background In addition to hypoxia, oxidative stress and inflammation due to carbon monoxide (CO) poisoning cause adverse health effects. These mechanisms are related to the occurrence of autoimmune connective tissue disease, but studies on the association between CO poisoning and autoimmune connective tissue disease are limited. We conducted a study to evaluate the occurrence of autoimmune connective tissue disease following CO poisoning. Methods We identified participants with CO poisoning diagnosed between 1999 and 2012 from the Nationwide Poisoning Database and selected participants without CO poisoning from the Taiwan National Health Insurance Research Database with matching age and index dates at a 1:3 ratio. Sex, underlying comorbidities, and monthly income were also included in the analyses. We followed up the participants until 2013 and made comparison of the risk of autoimmune connective tissue disease between participants with and without CO poisoning. Results The 23,877 participants with CO poisoning had a higher risk for autoimmune connective tissue disease than the 71,631 participants without CO poisoning (adjusted hazard ratio [AHR], 3.5; 95% confidence interval [CI], 3.1–3.9) after adjustment for sex, diabetes, Lyme disease, herpes zoster, infectious mononucleosis, hepatitis, HIV infection, liver disease, renal disease, non-CO poisoning or drug abuse, malignancy, hypertension, hyperlipidemia, coronary artery disease, congestive heart failure, chronic obstructive pulmonary disease, and monthly income. An increased risk was observed even after 4 years of follow-up (AHR, 3.6; 95% CI, 3.0–4.4). Conclusion The risk of autoimmune connective tissue disease increased following CO poisoning. Close follow-up of the patients with CO poisoning for the development of connective tissue disease is recommended, and further investigation of the detailed mechanisms is warranted.

Abstract
OBJECTIVE Chronic pain (CP) may increase the risk for major adverse cardiac and cerebrovascular events (MACCEs); however, this issue is still unclear in the Asian population. We conducted this study to delineate it. DESIGN From the Taiwan National Health Insurance Research Database, we identified 17,614 participants (<65 years) with CP and matched them by age and sex at a 1:2 ratio to participants without CP, who made up the comparison cohort. Several causes of CP and its underlying comorbidities were also analyzed. OUTCOME MEASURE A comparison of MACCE occurring in the two cohorts was performed via follow-up until 2015. RESULTS The mean age (SD) was 50.2 (11.5) years and 50.4 (11.7) years in participants with and without CP, respectively. In both cohorts, the percentage of female participants was 55.5%. Common causes of CP were spinal disorders (23.9%), osteoarthritis (12.4%), headaches (11.0%), gout (10.2%), malignancy (6.2%), and osteoporosis (4.5%). After adjusting for hypertension, diabetes, chronic obstructive pulmonary disease, renal diseases, hyperlipidemia, liver diseases, dementia, and depression, participants with CP had a higher risk for MACCE than those without CP (adjusted hazard ratio [AHR] = 1.3, 95% confidence interval [CI] = 1.3 - 1.4). After conducting subgroup analyses, an increased risk was also found for all-cause mortality (AHR = 1.4, 95% CI = 1.1 - 1.8), acute myocardial infarction (AHR = 1.2, 95% CI = 1.0 - 1.4), and stroke (AHR = 1.3, 95% CI = 1.3 - 1.4). CONCLUSIONS CP is associated with increased occurrence of MACCE. Early detection and interventions for CP are suggested.

Abstract
BACKGROUND A hyperglycemic crisis episode (HCE) signifies poor control of diabetes and may increase the risk of dementia via microvascular and macrovascular injuries. OBJECTIVES We conducted this study to clarify this issue, which remains unclear. METHODS Using the Taiwan National Health Insurance Database, we identified 9,466 diabetic patients with HCE and the identical number of diabetic patients without HCE who were matched by age and sex for this nationwide population-based cohort study. The risk of dementia was compared between the 2 cohorts by following up until 2014. Investigation of independent predictors of dementia was also done. RESULTS In the overall analysis, the risk of dementia between the 2 cohorts was not different. However, stratified analyses showed that patients with HCE had a higher risk of subsequent dementia in the age subgroup of 45-54 and 55-64 years (adjusted odds ratio [AOR]: 2.4, 95% confidence interval [CI]: 1.6-3.6, and AOR: 1.2, 95% CI: 1.0-1.5, respectively). In the overall analysis, older age, female sex, ≥3 HCEs, hypertension, hyperlipidemia, depression, cerebrovascular disease, Parkinson's disease, and head injury were independent predictors. CONCLUSIONS HCE increased the risk of dementia in diabetic patients aged 45-64 years. Dementia was predicted by ≥3 HCEs. Prevention of recurrent HCE, control of comorbidities, and close follow-up of cognitive decline and dementia are suggested in patients with HCE.

Abstract
Discovery of novel classes of Gram-negative antibiotics with activity against multi-drug resistant infections is a critical unmet need. As an essential member of the lipoprotein biosynthetic pathway, lipoprotein signal peptidase II (LspA) is an attractive target for antibacterial drug discovery, with the natural product inhibitor globomycin offering a modestly-active starting point. Informed by structure-based design, the globomycin depsipeptide was optimized to improve activity against E. coli. Backbone modifications, together with adjustment of physicochemical properties, afforded potent compounds with good in vivo pharmacokinetic profiles. Optimized compounds such as 51 (E. coli MIC 3.1 μM) and 61 (E. coli MIC 0.78 μM) demonstrate broad spectrum activity against gram-negative pathogens and may provide opportunities for future antibiotic discovery.

Abstract
Background The explanation of epidural analgesia by anesthesiologist would often begin after the parturient is admitted to the hospital. Because of labor pain, the decision of receiving epidural analgesia would often be made by the family members, instead of the parturient herself. We aimed to test whether earlier prenatal shared decision-making (SDM) interventions increase parturient’s comprehension and satisfaction of epidural labor analgesia, compared to conventional explanation after labor pain begun. Methods During the 28th week of gestation, we provided the SDM parturient health education as well as a leaflet with quick response codes. Scanning the code would link to education videoclips which explained what epidural analgesia is and its advantages and disadvantages. Original routine practice group parturients received explanation of analgesia after admission for delivery. To measure the satisfaction of labor pain service, the accessibility of information, and the communication with medical staff, we designed a questionnaire with reference to (1) Pregnancy and Maternity Care Patients’ Experiences Questionnaire (PreMaPEQ), (2) Preterm Birth Experience and Satisfaction Scale (P-BESS), and (3) Women’s Views of Birth Labor Satisfaction Questionnaire (WOMBLSQ). The questionnaire was amended after a pretest involving 30 parturients who had received epidural analgesia. Scree test analysis and exploratory factor analysis were performed; then, the questionnaire was revised again. A total of 200 valid questionnaires were collected—100 each from the original routine practice group and the SDM group. Results The SDM group reported significantly higher satisfaction with and understanding of epidural analgesia, and a significantly higher satisfaction with the information received, and the quality of pain relief. After SDM intervention, significant increasement of the average satisfaction scores in question “my epidural is effective” (9.10%; mean difference: 0.38; 95% confidence interval, 0.17 ~ 0.59; p < 0.001) and “The effect of epidural is just as what I have expected” (10.41%; mean difference: 0.41; 95% confidence interval, 0.18 ~ 0.64; p < 0.001) was demonstrated. Conclusions An earlier prenatal SDM intervention with sufficient information through videoclips increased parturients’ comprehensions and satisfaction of epidural analgesia service.

Abstract
BACKGROUND Recent years have witnessed wide applications of exergames to balance training among the older adults. However, research concerning balance training with the use of Kinect for Xbox has remained scarce. While previous studies have shown the positive effects of exergames on improving balance and preventing falling among the older adults, there has been a paucity of empirical evidence supporting the superiority of Kinect exercise to conventional exercise over balance training among the older adults. Therefore, this study aimed to compare the feasibility, safety, and effectiveness of Kinect exercise against conventional exercise over balance training among the community older adults. METHOD A total of 20 participants were randomly assigned to the Kinect Exercise Group (N = 10) or the Conventional Exercise Group (N = 10) for a 5-week balance training (45 minutes a time, 2 times a week). Assessor blinding was employed to assess the participants' performance before and after the treatment, including 30-Second Chair Stand Test (30-sec CST), Timed Up and Go (TUG), Functional Reach Test (FRT), and One-Leg Stance Test (OLST) respectively with eyes open and closed. Subjective feeling of the intensity of pain and side effects were recorded throughout the investigation period. Nonparametric statistics was used for data analysis. RESULTS Within-group comparison between the pre-test and post-test indicated that significant differences existed in all of the 5 tests (30-sec CST, TUG, FRT, OLST with eyes open, and OLST with eyes closed) in the Kinect exercise group. To the Conventional exercise group, however, significant differences were only observed in 30-sec CST, FRT and OLST with eyes open. With regard to between-group comparison, significant differences were only found in FRT. CONCLUSION Such results indicated that both treatments were helpful in improving the participants' balance performance, that Kinect exercise was more effective in terms of overall balance ability, and that Kinect exercise was particularly beneficial to functional reach enhancement in comparison with traditional exercise. Kinect exercise could be a feasible, safe, and effective alternative for dynamic balance training among older adults.

ASIAN-AUSTRALASIAN JOURNAL OF ANIMAL SCIENCES 2020; 33:888-901. [PMID: 31480142 PMCID: PMC7206370 DOI: 10.5713/ajas.19.0175] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/04/2019] [Revised: 06/06/2019] [Accepted: 08/14/2019] [Indexed: 11/27/2022]
Abstract
OBJECTIVE A set of microsatellite markers with high polymorphism from Tsaiya duck were used for the genetic monitoring and genetic structure analysis of Brown and White Tsaiya duck populations in Taiwan. METHODS The synthetic short tandem repeated probes were used to isolate new microsatellite markers from the genomic DNA of Tsaiya ducks. Eight populations, a total of 566 samples, sourced from Ilan Branch, Livestock Research Institute were genotyped through novel and known markers. The population genetic variables were calculated using optional programs in order to describe and monitor the genetic variability and the genetic structures of these Tsaiya duck populations. RESULTS In total 24 primer pairs, including 17 novel microsatellite loci from this study and seven previously known loci, were constructed for the detection of genetic variations in duck populations. The average values for the allele number, the effective number of alleles, the observed heterozygosity, the expected heterozygosity, and the polymorphism information content were 11.29, 5.370, 0.591, 0.746, and 0.708, respectively. The results of analysis of molecular variance and principal component analysis indicated a contracting Brown Tsaiya duck cluster and a spreading White Tsaiya duck cluster. The Brown Tsaiya ducks and the White Tsaiya ducks with Pekin ducks were just split to six clusters and three clusters when K was set equal to 6 and 3 in the Bayesian cluster analysis. The individual phylogenetic tree revealed eight taxa, and each individual was assigned to its own population. CONCLUSION According to our study, the 24 novel microsatellite markers exhibited a high capacity to analyze relationships of inter- and intra-population in those populations with a relatively limited degree of genetic diversity. We suggest that duck farms in Taiwan could use the new (novel) microsatellite set to monitor the genetic characteristics and structures of their Tsaiya duck populations at various intervals in order to ensure quality breeding and conservation strategies.

Abstract
Objective: To investigate the imaging findings of 2019 novel coronavirus pneumonia (COVID-19). Methods: From January 20 to February 5, 2020, a total of 130 patients diagnosed with COVID-19 from seven hospitals in China were collected. The imaging data were reviewed and analyzed in detail. Results: (1) Distribution: the lesion detected in the lung unilaterally in 14 cases (10.7%) and bilaterally in 116 cases (89.3%). According to the distribution in the lobes of the lung, all cases could be classified into subpleural distribution (102 cases, 78.4%), centrilobular distribution (99 cases, 76.1%) and diffused distribution (8 cases, 6.1%). (2) Number of lesions: single lesion 9 cases (6.9%); multiple lesions 113 cases (86.9%), diffuse lesions 8 cases (6.1%). (3) Imaging density: 70 cases (53.8%) of ground-glass opacity (GGO), 60 cases (46.2%) of GGO+consolidation. (4) Accompanying signs: 100 cases (76.9%) with vascular thickening, 98 cases (75.3%) with "pleural parallel sign" ; " intralobular septal thickening" in 100 cases (76.9%); "halo sign" in 13 cases (10%); "reversed-halo sign" in 6 cases (4.6%); pleural effusion in 3 cases (2.3%), and pneumatocele in 2 cases (1.5%); no case with pulmonary cavity. Among 35 patients that underwent follow-up CT, 21 patients (60%) improved while 14 (40%) exacerbated. Conclusions: COVID-19 imaging characteristic mainly has subpleural, centrilobular and diffused distribution. The first two distributions can overlap or progress to diffused distribution. In the later period, it was mainly manifested as organizing pneumonia and fibrosis. The most valuable characteristic is the pleural parallel sign.

Abstract
Salmonellosis in broilers is not merely a significant disease with high economic costs in the poultry industry but also the foodborne disease with the impact on public health by cross-contamination. This study was to investigate the prebiotic ability of trehalose supplementing in diets (0, 1, 3, and 5%, w/w) against Salmonella by using S. Typhimurium (ST)-inoculated broilers. The improvements (P < 0.05) of feed conversion ratio (FCR) were observed with 5% trehalose supplementation in ST-inoculated broilers' diets. An addition of 3 or 5% trehalose in diets increased (P < 0.05) the abundance of lactobacilli in the duodenum and jejunum but decreased (P < 0.05) the growth of ST in the cecum. The adverse effects on serum levels of aspartate aminotransferase, triglyceride, and albumin and globulin ratio in ST-inoculated broilers were noticed and counteracted by supplementing 3 or 5% trehalose in diets (P < 0.05). Besides, the inclusion of trehalose in diets alleviated the intestinal damages and maintained the integrity of cecal epithelial cells after ST challenge under an haematoxylin and eosin-staining observation. Supplementing trehalose further showed the inhibitions of toll-like receptor 4-mediated nuclear factor-kappa-B pathway, including the downregulation (P < 0.05) of proinflammatory cytokine genes, such as interleukin 1 beta and lipopolysaccharide-induced tumor necrosis factor-alpha factor and the upregulation (P < 0.05) of interleukin 10 and interferon-alpha in ST-inoculated broilers. Overall, supplementing trehalose alleviated the adverse effects from ST challenge on FCR, serum biochemistry, the damage, and inflammation in the liver and cecum. Those improvements on ST challenged broilers also contributed to the overgrowth of lactobacilli, the decrement of ST, and anti-inflammatory effects in affected broilers. Trehalose, therefore, could be a promising prebiotic against salmonellosis to benefit broiler production and promote food safety in the poultry industry.

Abstract
BACKGROUND An imbalanced fat or excess energy intake always results in obesity and increased serum/liver lipids, thus leading to metabolic syndromes. Given the bioactive components in black vinegar (BV), such as branched amino acids, phenolic profile, and mineral contents, we investigated the antiobesity effects of BV-based supplements in rats fed a high-fat diet (HFD). RESULTS HFD (30% fat, w/w) feeding increased (P < 0.05) body weight, weight gains, weights of livers and mesenteric, epididymal, and perirenal adipose tissues, and serum/liver triglyceride levels relative to those of rats fed a normal diet (4% fat, w/w; CON). These increased values were ameliorated (P < 0.05) by supplementing with BV-based supplements but were still higher (P < 0.05) than those of CON rats. The increased areas of perirenal adipocytes in rats fed with an HFD were also decreased (P < 0.05) by supplementing with BV-based supplements, which might result from an upregulation (P < 0.05) of 5'-adenosine monophosphate-activated protein kinase (AMPK), carnitine palmitoyltransferase-1 (CPT1), and uncoupling protein-2 (UCP2) in the perirenal adipose tissues. A similar effect was observed for AMPK, peroxisome proliferator-activated receptor alpha, retinoid X receptor alpha, CPT1, and UCP2 gene and protein levels in livers (P < 0.05). Generally, BV-based supplements increased the fecal triglyceride, cholesterol, and bile acid levels of rats fed with an HFD, which partially contribute to the lipid-lowering effects. Furthermore, BV-based supplements increased (P < 0.05) hepatic Trolox equivalent antioxidant capacity and lowered (P < 0.05) serum/liver thiobarbituric acid reactive substances values in HFD-fed rats. CONCLUSION In a chronic high-fat dietary habit, the food-grade BV-based supplement is a good daily choice to ameliorate obesity and its associated comorbidities. © 2020 Society of Chemical Industry.

Cardiac protection of functional chicken-liver hydrolysates on the high-fat diet induced cardio-renal damages via sustaining autophagy homeostasis.

Abstract
BACKGROUND Cardio-renal syndrome (CRS) is an integrative problem related to chronic malnutrition, obesity, etc. Amino acids and peptides are regarded as protective and essential for tissues. Pepsin-digested chicken liver hydrolysates (CLHs), which are made from the byproducts of the poultry industry, are amino-acid based and of animal origin, and may be protective against the myocardial and renal damage induced by a high-fat diet (HFD). RESULTS Our results showed that CLHs contain large quantities of anserine, taurine, and branched-chain amino acids (BCAAs), and supplementing the diet with CLHs reduced (P < 0.05) weight gain, liver weight, peri-renal fat mass / adipocyte-area sizes, serum total cholesterol (TC), aspartate aminotransferase (AST), and low-density lipoprotein cholesterol (LDLC) levels in HFD-fed mice but increased (P < 0.05) serum high-density lipoprotein cholesterol (HDLC) levels. By histological analyses, CLHs alleviated (P < 0.05) renal lipid deposition and fibrosis, as well as cardiac fibrosis and inflammation of HFD-fed mice. Meanwhile, increased (P < 0.05) inflammatory and fibrotic cytokines levels in the myocardia of the HFD-fed mice were downregulated (P < 0.05) by CLH supplementation. Regarding autophagy-related protein levels, protective effects of CLHs on the myocardia against HFD feeding may result from the early blockade of the autophagy pathway to prevent autophagosome accumulation. CONCLUSION Functional CLHs could be a novel food ingredient as a cardio-renal protective agent against a high-fat dietary habit in a niche market. © 2020 Society of Chemical Industry.

Abstract
Infection with bovine leukaemia virus (BLV), a retrovirus, causes dysfunction of the immune system and can have a marked economic impact on dairy industries due to decreased milk production and reduced lifespan in affected dairy cattle. The presence of proviral DNA has been the major diagnostic indicator of BLV infection. However in the course of BLV infection, the viral genome can be dormant, without detectable gene expression, resulting in limited impact on infected animals. At present, there is limited knowledge regarding haematological indices in dairy cattle that could indicate activation of the BLV genome and suggest reactivated BLV infection. In this study, BLV infection and BLV genome reactivation were evaluated based on the presence of BLV DNA and BLV env gene transcripts, respectively. BLV RNA transcription was confirmed. Among 93 whole blood samples obtained from asymptomatic dairy cattle, the prevalence of BLV proviral DNA and transcripts was 93.5% (n = 87/93) and 83.9% (n = 78/93), respectively. Between groups with and without BLV, the mean counts of white blood cells and lymphocytes in whole blood were significantly associated with the presence of BLV RNA (P < 0.05), but not with BLV proviral DNA. These results shed light on the activation status of the BLV genome and should be taken into account when evaluating the possible impact of BLV on cattle.

Ameliorative effects of functional chalaza hydrolysates prepared from protease-A digestion on cognitive dysfunction and brain oxidative damages. Poult Sci 2020; 99:2819-2832. [PMID: 32359619 PMCID: PMC7597535 DOI: 10.1016/j.psj.2019.12.060] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2019] [Revised: 12/17/2019] [Accepted: 12/21/2019] [Indexed: 11/27/2022] Open
Abstract
Our patented protease A–digested crude chalaza hydrolysates (CCH) show antioxidant abilities in vitro. The prophylactic effects of CCH on cognitive dysfunction and brain oxidative damages were investigated via a D-galactose (DG)–injected mouse model in this study. Fifty-four mice were randomly divided into the following: (1) CON, 0.1 mL 0.9% saline (subcutaneous injection [SC] on the back)+distilled water (oral gavage); (2) DG, 100 mg/kg BW/day D-galactose (Bio-Serv Co., Flemington, NJ, USA) (SC on the back)+distilled water (oral gavage); (3) DG_LCH, 100 mg/kg BW/day D-galactose (SC on the back) + 50 mg CCH/kg BW/day in 0.1 ml distilled water (oral gavage); (4) DG_MCH, 100 mg/kg BW/day D-galactose (SC on the back) + 100 mg CCH/kg BW/day (oral gavage); (5) DG_HCH, 100 mg/kg BW/day D-galactose (SC on the back) + 200 mg CCH/kg BW/day (oral gavage); (6) DG_AG, 100 mg/kg BW/day D-galactose (SC on the back) + 100 mg aminoguanidine hydrochloride/kg BW/day (oral gavage). The experiment lasted for 84 D. CCH, containing antioxidant-free amino acids and anserine, restored (P < 0.05) DG-injected memory injury in the Morris water maze test and attenuated the neuronal degenerations and nucleus shrinkages in the dentate gyrus area. CCH supplementation also reduced amyloid β-peptide protein levels and accumulation of advanced glycation end products (AGE) in the brain of DG-injected mice, whereas the brain antioxidant capacity was reversed (P < 0.05) by supplementing CCH. Furthermore, AGE receptor (RAGE), NFκb, IL-6, and TNF-α gene expressions were downregulated (P < 0.05) by supplementing CCH. Therefore, CCH show prophylactic effects on the development of oxidative stress-induced cognitive dysfunction.

Abstract
CC-type chemokine ligand 5 (CCL5) has been known to regulate immune responses by mediating the chemotaxis of leukocytes. Depending on the environment, CCL5 forms different orders of oligomers to interact with targets and create functional diversity. A recent CCL5 trimer structure revealed that the N-terminal conversed F12-A13-Y14 (12FAY14) sequence is involved in CCL5 aggregation. The CCL5-12AAA14 mutant with two mutations had a deficiency in the formation of high-order oligomers. In the study, we clarify the respective roles of F12 and Y14 through NMR analysis and structural determination of the CCL5-12AAA14 mutant where F12 is involved in the dimer assembly and Y14 is involved in aggregation. The CCL5-12AAA14 structure contains a unique dimer packing. The backbone pairing shifts for one-residue in the N-terminal interface, when compared to the native CCL5 dimer. This difference creates a new structural orientation and leads to the conclusion that F12 confines the native CCL5 dimer configuration. Without F12 anchoring in the position, the interfacial backbone pairing is permitted to slide. Structural plasticity occurs in the N-terminal interaction. This is the first case to report this structural rearrangement through mutagenesis. The study provides a new idea for chemokine engineering and complements the understanding of CCL5 oligomerization and the role of the 12FAY14 sequence.

Abstract
This nationwide retrospective case-control study was aimed at elucidating the risk from cataract surgery in end-stage renal disease (ESRD) patients. Cataract surgery patients were identified using the diagnostic and procedural codes for International Classification of Diseases, 9th Revision, Clinical Modification from Taiwan’s National Health Insurance Research Database. ESRD patients were selected as cases, while propensity scores for age, sex, comorbidities and year-of-surgery-matched patients without chronic kidney disease constituted the controls. Patients who had undergone eye surgery within 3 years before cataract surgery were excluded. The main outcome measures were target cataract surgery-related complications within 3 months after surgery. A total of 352 cases and 1,760 controls were analysed. Patients with ESRD had a 5.06-fold (95% CI: 2.36–10.87; p < 0.001) risk of vitreous haemorrhage and a 2.74-fold (95% CI: 1.20–6.27; p = 0.017) risk of re-operation for dropped nucleus or vitreous complications. Non-diabetic ESRD patients had a 3.49-fold (95% CI: 1.36–8.91; p = 0.009) risk of corneal oedema. In conclusion, ESRD patients have a higher risk of vitreous haemorrhage, re-operation for dropped nucleus or vitreous complications and corneal oedema (non-diabetic patients) after cataract surgery. Pre-surgery corneal examination, surgery procedure and medication adjustment, closer and longer post-surgery follow-up may lower the risk and improve the visual outcome.

Abstract
Objective: The consistency of 24-hour oropharyngeal Dx-pH monitoring and proton pump inhibitor(PPI) test in the diagnosis of laryngopharyngeal reflux disease (LPRD) was investigated. Methods: Sixty patients with laryngopharyngeal reflux (LPR) related symptoms who had never received PPI treatment were assessed by reflux symptom index (RSI) and reflux finding score (RFS) between October 2017 and October 2018, including 28 males and 38 females, aged from 16 to 72 years, with a medium age of 38 years. Prior to treatment, all patients were evaluated with 24 hours oropharyngeal Dx-pH monitoring(Restech). After empiric therapy with PPI twice-daily for 8 weeks, the efficacy was evaluated according to posttreatment RSI score.The data was analysed with Kruskal-Wallis test, Student Newman Keuls test and consistency check. Results: (1)Among all 60 patients,13 patients (21.7%) had pathologic Ryan score and all resulted responsive to PPI;27 patients (45.0%) with a negative Ryan score were unresponsive to PPI; 20 patients (33.3%) despite a negative Ryan score resulted responsive to PPI therapy. Considering responsiveness to PPI therapy as the gold standard for the diagnosis of LPRD, the sensitivity, specificity, positive predictive value and negative predictive value of Ryan score were 39.4%, 100%, 100% and 57.4% respectively. The Kappa value was 0.369 (P<0.01). (2)Among 34 patients (56.7%) with positive Dx-pH results (24-hour oropharyngeal acid reflux events≥ 3 times), 29 patients were positive and 5 patients were negative in PPI test. Among 26 patients with negative Dx-pH results (24-hour oropharyngeal acid reflux events<3 times), 4 patients were positive and 22 patients were negative in PPI test. Considering responsiveness to PPI therapy as the gold standard for the diagnosis of LPRD, the sensitivity, specificity, positive predictive value and negative predictive value of 24-hour oropharyngeal acid reflux events were 87.9%, 81.5%, 85.3% and 84.6% respectively. The Kappa value was 0.696(P<0.01). Conclusions: There is a positive correlation between 24-hour oropharyngeal Dx-pH monitoring positive results (24-hour oropharyngeal acid reflux events≥3 times) and PPI test in the diagnosis of LPRD. The 24-hour oropharyngeal Dx-pH monitoring can be a promising tool for the diagnosis of suspected LPRD patients, and more sensitive and accurate Dx-pH diagnostic index will be required in the clinic.
