RESUMO

Mandarin peel, a main by-product from the processing of citrus juice, has been highlighted for its various bioactivities and functional ingredients. Our previous study proved the inhibitory effects of Celluclast extract from mandarin peel (MPCE) on lipid accumulation and differentiation in 3T3-L1 adipocytes. Therefore, the current study aimed to evaluate the anti-obesity effect of MPCE in high-fat diet (HFD)-induced obese mice. The high-performance liquid chromatography (HPLC) analysis exhibited that narirutin and hesperidin are the main active components of MPCE. Our current results showed that MPCE supplementation decreased adiposity by reducing body and organ weights in HFD-induced obese mice. MPCE also reduced triglyceride (TG), alanine transaminase (ALT), aspartate transaminase (AST), and leptin contents in the serum of HFD-fed mice. Moreover, MPCE significantly inhibited hepatic lipid accumulation by regulating the expression levels of proteins associated with lipid metabolism, including sterol regulatory element-binding protein (SREBP1c), fatty acid synthase (FAS), and acetyl-CoA carboxylase (ACC). Furthermore, MPCE administration significantly inhibited both adipogenesis and lipogenesis, with modulation of energy metabolism by activating 5' adenosine monophosphate-activated protein kinase (AMPK) and lipolytic enzymes such as hormone-sensitive lipase (HSL) in the white adipose tissue (WAT). Altogether, our findings indicate that MPCE improves HFD-induced obesity and can be used as a curative agent in pharmaceuticals and nutraceuticals to alleviate obesity and related disorders.

RESUMO

BACKGROUND: Most crop seeds are F1 hybrids. Seed providers and plant breeders must be confident that the seed supplied to growers is of known, and uniform, genetic makeup. This requires maintenance of pure genotypes of the parental lines and testing to ensure the genetic purity of the F1 seed. Traditionally, seed purity has been assessed with a grow-out test (GOT) in the field, a time consuming and costly venture. Early in the last decade, seed testing with molecular markers was introduced as a replacement for GOT, and Kompetitive allele specific PCR (KASP) markers were recognized as promising tools for genetic testing of seeds. However, the markers available at that time could be inaccurate and applicable to only a small number of accessions or varieties due to the limited genetic information and reference genomes available. RESULTS: We identified 4,925,742 SNPs in 50 accessions of the Brasscia rapa core collection. From these, we identified 2,925 SNPs as accession-specific, considering properties of flanking region harboring accession-specific SNPs and genic region conservation among accessions by the Next Generation Sequencing (NGS) analysis. In total, 100 accession-specific markers were developed as accession-specific KASP markers. Based on the results of our validation experiments, the accession-specific markers successfully distinguised individuals from the mixed population including 50 target accessions from B. rapa core collection and the outgroup. Additionally, the marker set we developed here discriminated F1 hybrids and their parental lines with distinct clusters. CONCLUSIONS: This study provides efficient methods for developing KASP markers to distinguish individuals from the mixture comprised of breeding lines and germplasms from the resequencing data of Chinese cabbage (Brassica rapa spp. pekinensis).

RESUMO

The B-box zinc-finger transcription factors are important for plant growth, development, and various physiological processes such as photomorphogenesis, light signaling, and flowering, as well as for several biotic and abiotic stress responses. However, there is relatively little information available regarding Brassica B-box genes and their expression. In this study, we identified 51, 52, and 101 non-redundant genes encoding B-box proteins in Brassica rapa (BrBBX genes), B. oleracea (BoBBX genes), and B. napus (BnBBX genes), respectively. A whole-genome identification, characterization, and evolutionary analysis (synteny and orthology) of the B-box gene families in the diploid species B. rapa (A genome) and B. oleracea (C genome) and in the allotetraploid species B. napus (AC genome) revealed segmental duplications were the major contributors to the expansion of the BrassicaBBX gene families. The BrassicaBBX genes were classified into five subgroups according to phylogenetic relationships, gene structures, and conserved domains. Light-responsive cis-regulatory elements were detected in many of the BBX gene promoters. Additionally, BrBBX expression profiles in different tissues and in response to various abiotic stresses (heat, cold, salt, and drought) or hormones (abscisic acid, methyl jasmonate, and gibberellic acid) were analyzed by qRT-PCR. The data indicated that many B-box genes (e.g., BrBBX13, BrBBX15, and BrBBX17) may contribute to plant development and growth as well as abiotic stress tolerance. Overall, the identified BBX genes may be useful as functional genetic markers for multiple stress responses and plant developmental processes.

RESUMO

BACKGROUND: The incidence of non-tuberculous mycobacteria (NTM) isolation from humans is increasing worldwide. In England, Wales and Northern Ireland (EW&NI) the reported rate of NTM more than doubled between 1996 and 2006. Although NTM infection has traditionally been associated with immunosuppressed individuals or those with severe underlying lung damage, pulmonary NTM infection and disease may occur in people with no overt immune deficiency. Here we report the incidence of NTM isolation in EW&NI between 2007 and 2012 from both pulmonary and extra-pulmonary samples obtained at a population level. METHODS: All individuals with culture positive NTM isolates between 2007 and 2012 reported to Public Health England by the five mycobacterial reference laboratories serving EW&NI were included. RESULTS: Between 2007 and 2012, 21,118 individuals had NTM culture positive isolates. Over the study period the incidence rose from 5.6/100,000 in 2007 to 7.6/100,000 in 2012 (p < 0.001). Of those with a known specimen type, 90 % were pulmonary, in whom incidence increased from 4.0/100,000 to 6.1/100,000 (p < 0.001). In extra-pulmonary specimens this fell from 0.6/100,000 to 0.4/100,000 (p < 0.001). The most frequently cultured organisms from individuals with pulmonary isolates were within the M. avium-intracellulare complex family (MAC). The incidence of pulmonary MAC increased from 1.3/100,000 to 2.2/100,000 (p < 0.001). The majority of these individuals were over 60 years old. CONCLUSION: Using a population-based approach, we find that the incidence of NTM has continued to rise since the last national analysis. Overall, this represents an almost ten-fold increase since 1995. Pulmonary MAC in older individuals is responsible for the majority of this change. We are limited to reporting NTM isolates and not clinical disease caused by these organisms. To determine whether the burden of NTM disease is genuinely increasing, a standardised approach to the collection of linked national microbiological and clinical data is required.

RESUMO

BACKGROUND: Simultaneous genotyping has advantages in turnaround time and detecting the real mutational prevalence in unresectable non-small-cell lung cancer (NSCLC), a group not previously genetically characterized. METHODS: We developed simultaneous panel of screening EGFR and KRAS mutations by direct sequencing or PNA clamping, and ALK rearrangement by fluorescent in situ hybridization (FISH) in multicenter manner. RESULTS: Of 510 NSCLC Korean patients, simultaneous genotyping identified mutations of EGFR (29.0%) and KRAS (8.6%) and rearrangement of ALK (9.2%). Seven patients had overlaps in mutations. Although several well-known associations between genotypes and clinical characteristics were identified, we found no relationship between ALK rearrangement and sex or smoking history. Unlike the other genotype mutations, ALK rearrangement was associated with advanced disease. Among the ALK-negative group, patients with 10-15% of ALK FISH split shared characteristics, such as younger age and advanced stage disease, more with the ALK-positive group (>15% ALK FISH split) than <10% ALK FISH split group. CONCLUSIONS: Simultaneous panel genotyping revealed more prevalent ALK rearrangements than reported in previous studies and their strong association with advanced stage irrespective of sex or smoking history. ALK rearrangement seems to be a marker for aggressive tumor biology and should be assessed in advanced disease.

RESUMO

The effect of Coriolus versicolor extract supplemented diets on innate immune response and disease resistance in kelp grouper, Epinephelus bruneus against Listonella anguillarum, is reported. Kelp grouper were divided into four groups of 25 each and fed with C. versicolor enriched diets at 0% (control), 0.01%, 0.1%, and 1.0% level. After 30 days of feeding, all fish were injected interaperitoneally (i.p.) with 50 µl of L. anguillarum (4.7 × 10(7) CFU) to investigate the immune parameters at weeks 1, 2, and 4. The reactive oxygen species and reactive nitrogen species production were significantly enhanced in fish fed with 0.1% and 1.0% supplementation diets from weeks 1-4 when compared to the non enriched diet fed and infected control. The phagocytic activity significantly increased with 0.1% and 1.0% diets on weeks 2 and 4. The leucocyte myeloperoxidase content, lysozyme activity, and total protein level significantly increased when fed with 0.1% and 1.0% supplementation diets from weeks 1-4. The cumulative mortality was 35% and 45% in 1.0% and 0.1% enriched diet fed groups whereas it was 55% and 80% in 0.01% and 0% groups respectively. The present results suggest that diets enriched with C. versicolor at 0.1% or 1.0% level positively enhance the innate immune system and affords protection from L. anguillarum.

RESUMO

The present study investigated the effect of 1.0% chitin and chitosan supplementation diets on haematology and immune response in Kelp grouper, Epinephelus bruneus against protozoan parasite, Philasterides dicentrarchi. The red blood cells (RBC), white blood cells (WBC), haemoglobin levels, lymphocytes, monocytes, and neutrophils significantly increased in kelp grouper fed with chitin or chitosan enriched diets against P. dicentrarchi. The mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), and thrombocytes did not significantly change against pathogen. The phagocytic activity, respiratory burst activity, complement activity, antiprotease activity, and α2-macroglobulin were significantly enhanced in fish fed with 1% chitin and chitosan diet on weeks 2 and 4. The lysozyme activity, total protein, and myeloperoxidase activity significantly increased in fish fed with chitin or chitosan supplementation diet from weeks 1 to 4 against pathogen. The cumulative mortality was found low in fish fed with chitin and chitosan enriched diets than those of control against pathogen. The present study suggests that supplementation of 1.0% chitin or chitosan in diets positively enhances immune response and affords disease resistance in kelp grouper, E. bruneus against P. dicentrarchi infection.

RESUMO

Philasterides dicentrarchi is a histophagous scuticociliate infecting Korean olive flounder farms in Jeju Island, South Korea, where it causes significant economic losses. However, the route of entry of these parasites in olive flounder is currently unknown. In the present study, we attempted experimental infection with different doses (concentrations) of P. dicentrarchi by intraperitoneal (IP) injection; maximum cumulative mortality of 95% was recorded on the administration of 2.1×10(8) ciliates/ml. In small size group (3 cm length, 24±2 gwt) the ciliates were found in connective tissues of muscle, fins, and nervous tissue while in large size group (5 cm length, 47±3 gwt), the ciliates were predominantly occurred with associated symptoms of liquefaction in the central nervous system. The major clinico-pathological manifestations were loss of scales, appearance of bleached spots that coalesced to form brownish patches, hemorrhagic, and severe dermal necrotic lesion. In addition there was degeneration of muscle fibers, necrosis of the hepatic parenchyma, and severe edema of the intestinal walls, extensive fouling, necrotic degeneration and hyperplasia in the gill bronchial epithelium. In this study, many ciliates were found in the blood vessel, brain, dorsal fins, muscle, kidney, and vertebra of infected flounder. The histopathological investigations are of significant importance in view of possible routes of entry into the host and doses of ciliates that trigger fast infection for potential utility of drugs as a strategy for the control of P. dicentrarchi in farmed olive flounder.

RESUMO

The effect of Suaeda maritima enriched diet on blood physiology, innate immune response, and disease resistance in olive flounder Paralichythys olivaceus against Miamiensis avidus on weeks 1, 2, and 4 was investigated. Feeding with any enriched diet and then challenging with M. avidus significantly increased white blood cells (WBC) on weeks 2 and 4; the red blood cells (RBC) significantly increased with 0.1% and 1.0% enriched diets on week 4. The hemoglobin (Hb) and hematocrit (Ht) levels significantly increased when fed with 0.1% and 1.0% supplementation diets on weeks 2 and 4. The mean corpuscular volume (MCV) did not significantly vary with any diet and time; however the mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) significantly increased with 0.1% and 1.0% supplementation diets on weeks 2 and 4. The leukocytes such as lymphocytes (Lym), monocytes (Mon), neutrophils (Neu) and biochemical parameters such as total protein (TP), glucose (GLU), and calcium (CAL) levels significantly increased in 0.1% and 1.0% supplementation diet fed groups on weeks 2 and 4. The serum lysozyme activity was significantly enhanced in 0.1% and 1.0% supplementation diet fed groups from weeks 1 to 4 when compared to the control (0% herbal extract enriched diet). The scuticocidal activity and respiratory burst activity were significantly enhanced when fish were fed with 0.1% and 1.0% supplementation diets from weeks 2 and 4. The protective effect in terms of cumulative mortality (50% and 40%) was low in groups on being fed with 0.1% and 1.0% supplemented diet. Therefore the present study suggested that 0.1% and 1.0% S. maritime-supplemented diets protect the hematological and biochemical parameters, improving the innate immunity, affording protection disease from M. avidus infection in olive flounder.

RESUMO

This study determines the effect of diet enriched with the herb Baical skullcap Scutellaria baicalensis, and/or probiotics Lactobacillus sakei BK19 in rock bream, Oplegnathus fasciatus (32 ± 3 g) against Edwardsiella tarda. The changes in haematological parameters, innate immune response, and disease resistance were investigated after 1, 3, and 6 weeks. The white blood cell count (WBC: 10(4) mm(-3)), red blood cell count (RBC: 10(6) mm(-3)), and haemoglobin (Hb: g dl(-1)) levels significant increased (P < 0.05) with mixed diet on 3rd and 6th week and probiotics enriched diet on 6th week. The haematocrit (Ht: %) level significantly increased (P < 0.05) when fed with mixed diet on weeks 1-6. Interestingly, in mixed diet group the lymphocytes (LYM), monocytes (MON), and neutrophils (NEU) significantly increased from week 1-6. The eosinophils (EOS) significantly increased in all the treated groups. In the probiotics or mixed diet groups the total protein (TP: g dl(-1)) increased significantly on weeks 3 and 6. The serum lysozyme activity significantly was enhanced in all the treated groups indicating an increase in the innate immunity level. Serum complement, antiprotease activities, reactive oxygen species (ROS) and reactive nitrogen species (RNS) production significantly increased from week 1-6 with mixed diet. The maximum protection against E. tarda was recorded in mixed diet group with a minimum cumulative mortality of 20% and a high relative percent survival (RPS) of 72.84. In the probiotics and herbal diet groups the cumulative mortality was 25% and 35% and RPS was 68.63 and 59.42, respectively. This study indicates that administration of probiotics or mixed diets can effectively minimize the mortality and restore the altered hematological parameters and enhancing the innate immunity in O. fasciatus against E. tarda.

RESUMO

Lysozymes are the key molecules in innate immune system and possess high bactericidal properties. In the present study, a full-length c-type lysozyme cDNA has been cloned and characterized by expressed sequence tag (EST) and rapid amplification of cDNA ends (RACE) techniques from kelp grouper, Epinephelus bruneus (Eb-CTL). The cDNA consists of 753 base pairs (bp) with a 432 bp open reading frame (ORF) that encodes 144 amino acids (aa) residues and polyadenylation signal sequence AATAAA. The deduced aa sequence polypeptide had a predicted molecular weight of 16 kDa and theoretical isoelectric point of 7.3. The deduced aa sequence have a long lysozyme domain which contains all catalytic sites and other conserved residues required for lysozyme activity. Pair-wise alignments showed a higher identity (76.4%) with Psetta maxima lysozyme and low identity (38.9%) with lysozymes of insect Bombyx mori. Interestingly, phylogenetic analysis revealed that the kelp grouper lysozyme was more closely related to other fish and vertebrate lysozymes. Quantitative real-time reverse transcriptase-PCR analysis showed that Eb-CTL transcripts are constitutively expressed in hematopoietic organs such as heart, spleen, and kidney after stimulation with LPS or infection with Vibrio anguillarum, indicating the involvement of Eb-CTL in the innate immunity of kelp grouper. This study is a first step on the genetics and functions of the c-type lysozyme in kelp grouper, and their role in anti-bacterial activity with reference to immunological properties which might have biotechnological applications.

RESUMO

Feeding kelp grouper, Epinephelus bruneus (26.1 ± 1.4), with 0%, 0.1%, 1.0%, and 2.0% Kalopanax pictus extract-supplementation diets, for 30 days reduced mortality on being challenged intraperitoneally 100 µl with bacterium Vibrio alginolyticus (2.1 × 10(7) cfu ml(-1)) and ciliate parasite Philasterides dicentrarchi (2.3 × 10(7) ciliates ml(-1)). The red blood cells (RBC), white blood cells (WBC), haemoglobin, haematocrit, lymphocytes, and monocytes levels significantly increased in kelp grouper fed with all doses of K. pictus-supplementation diets and challenged with bacterium and parasite when compared to control. However, the levels of mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), neutrophils, and thrombocytes did not significantly. The phagocytic activity, complement activity, and antiprotease activity did not significantly change in kelp grouper fed with 0.1% K. pictus-supplementation diets and challenged with bacterium and parasite. The respiratory activity, lysozyme activity, bactericidal activity, total protein level, and myeloperoxidase levels significantly increased in kelp grouper fed with all the doses of K. pictus-supplementation diet and challenged with bacterium and parasite. However, α2-macroglobulin level significantly increased with 1.0% diet, but not with 0.1% and 2.0% diets. Therefore this study suggests that 1.0% and 2.0% K. pictus-supplementation diets positively protected and enhanced the immune system in kelp grouper E. bruneus against V. alginolyticus and P. dicentrarchi infection.

RESUMO

The present study was reported the effect of probiotics and herbals mixture supplementation diet on growth, blood constituents, and nonspecific immune response in olive flounder Paralichthys olivaceus against Streptococcus parauberis on weeks 1, 2, 4, 6, 8, 10, and 12 after injected intraperitoneally (i.p.) with 50 µl of PBS (phosphate buffer saline) containing S. parauberis (2.1 × 107 CFU ml⁻¹). The initial weight did not significantly increased in supplementation diet group from 1 to 4 weeks, whereas it was significantly increased from weeks 6 to 12 as compared to fish fed without supplementation diet. The serum aspartate aminotransferase (SGOT) and alanine aminotransferase (SGPT) activities significantly increased from weeks 4 to 12 in infected fish fed with supplementation diet compared to fish fed without supplementation diet. However, the total protein (TP) and glucose (GLU) levels were significantly increased in infected fish fed with supplementation diet after 6 weeks. The phagocytic, respiratory burst, complement, and lysozyme activities significantly enhanced in infected fish fed with supplementation diet from weeks 4 to 12 as compared to fish fed without supplementation diet. These results suggested that different probiotics and herbals mixture supplementation diet enhanced the growth, blood biochemical constituents, and nonspecific immunity in olive flounder against S. parauberis.

RESUMO

The effect of five probiotics, Lactobacillus plantarum, Lactobacillus acidophilus, Lactobacillus sakei, Bacillus subtilis, and Saccharomyces cerevisiae as individual and mixed enriched diet on the seasonal prevalence, activity and intensity of Uronema marinum infection in olive flounder Paralichthys olivaceus is reported. The growth performance, feed efficiency, blood biochemistry, survival rate, and non-specific immune response of U. marinum infected olive flounder on week 0, 1, 2, 4, 6, and 8 were quantified. The prevalence and infection intensity reached a peak from June to December and then it declined from December to March. The scuticocidal activity in the serum was significantly higher when fed with L. plantarum, L. acidophilus, and S. cerevisiae diets on weeks 2-8. All enriched diets significantly enhanced the weight gain significantly between week 6 and 8; the feed efficiency registered a significantly increase from week 4 to 8 when compared to infected fish fed with control diet. Infected fish fed with L. plantarum-supplemented diet had higher survival rate than with other enriched diets. The serum aspartate aminotransferase (GOT) and alanine aminotransferase (GPT) levels significantly increased when fed with L. plantarum, L. acidophilus or S. cerevisiae-supplemented diet. Total protein (TP) and glucose (GLU) level significantly increased with any enriched diet from week 4 to 8. The superoxide anion production and serum lysozyme activity registered a significant increase when fed with L. plantarum, L. acidophilus, and S. cerevisiae-supplemented diet from week 4-8. The present study concludes that L. plantarum, L. acidophilus, and S. cerevisiae-supplemented diets act as immunostimulants enhancing the growth, feed efficiency, blood biochemistry, survival rate, and non-specific immune response in U. marinum infected olive flounder.

RESUMO

The effect of diets containing sodium alginate at 0, 0.5, 1.0, and 2.0 g kg⁻¹ following challenge with Streptococcus iniae in kelp grouper Epinephelus bruneus were assessed with reference to survival rate and innate immune parameters such as alternative complement, lysozyme, natural haemagglutination, respiratory burst, superoxide dismutase, and phagocytic activities on week 1, 2, and 4. Fish fed with sodium alginate containing diet at 1.0 and 2.0 g kg⁻¹ after being challenged with S. iniae had higher survival rates of 75% and 60%, respectively than those fed with control diet (0 g kg⁻¹). With any enriched diet the percentage of macrophages significantly decreased from week 1-4, while the percentage of neutrophils and lymphocytes significantly increased. The alternate complement activity, natural haemagglutination, and phagocytic activities of infected fish fed with sodium alginate containing diet at 1.0 g kg⁻¹ on week 2 and 1.0 and 2.0 g kg⁻¹ diets on week 4 were significantly higher when compared to the control. The lysozyme, respiratory bursts, and superoxide dismutase activities of fish fed with enriched diets at 1.0 and 2.0 g kg⁻¹ were significantly increased on week 2 and 4. We therefore recommend that at 1.0 or 2.0 g kg⁻¹ dietary administration of sodium alginate can enhance innate immunity and disease resistance in kelp grouper against S. iniae.

RESUMO

The present study investigated the effect of Eriobotrya japonica extracts at 0%, 0.1%, 1.0%, and 2.0% doses supplementation with feed on non-specific immune response, hematological and biochemical profile, and disease resistance against Vibrio carchariae in kelp grouper Epinephelus bruneus at weeks 1, 2, and 4. The white blood cell (WBC) significantly increased in fish fed with 0.1%, 1.0%, and 2.0% diets on weeks 1 and 2 when compared to the control. However, the glucose always decreased from the control except on week 2 against pathogen. The serum total protein, albumin, and globulin significantly increased at week 2 but they did not changed significantly at weeks 1 and 4. The superoxide anion, lymphokines production index, and phogocytosis did not significantly increased in any diet on the first week whereas it was significantly enhanced in 1.0% and 2.0% supplementation diets on weeks 2 and 4 against V. carchariae when compared to control. All diets significantly enhanced the serum lysozyme activity, bactericidal activity, and haemolytic complement activity from weeks 1-4 as compared to control. The serum agglutinating antibody titre did not significantly enhance on the first week whereas it was significantly enhanced on weeks 2 and 4. Fish fed with 1.0% and 2.0% doses diets was found lower mortality than 0.1% diet. Thus, this study suggested that 1.0% and 2.0% doses supplementation diets could be advocated to enhance the immune response and production disease from V. carchariae in E. bruneus.

RESUMO

Kelp grouper, Epinephelus bruneus, fed for 30 days with 0% (control), 0.1%, 1.0%, and 2.0% of Styrax japonica supplementation diets, led to reductions in mortality after being challenged with a bacterium (Vibrio harveyi) and a ciliate protozoan (Uronema marinum). The enriched diets significantly increased the survival rate as compared to the controls. The phagocytic and respiratory activities were significantly increased in kelp groupers given 1.0% and 2.0% enriched diets. The complement activity, lysozyme activity, serum bactericidal activity, and total protein level significantly increased with any enriched diet against the pathogens; however antiprotease activity and myeloperoxidase levels significantly increased only with 1.0% and 2.0% enriched diets while the α2-macroglobulin level was significantly enhanced with 1.0% enriched diet. The study suggests that incorporation of S. japonica at 1.0% and 2.0% level in the diet significantly enhances the immune responses in the kelp grouper E. bruneus against V. harveyi and U. marinum.

RESUMO

Chronic obstructive pulmonary disease (COPD) is one of the most frequently occurring concomitant diseases in patients with non-small cell lung cancer (NSCLC). It is characterized by small airways and the hyperinflation of the lung. Patients with hyperinflated lung tend to have more reserved lung function than conventionally predicted after lung cancer surgery. The aim of this study was to identify other indicators in predicting postoperative lung function after lung resection for lung cancer. Patients with NSCLC who underwent curative lobectomy with mediastinal lymph node dissection from 2017 to 2019 were included. Predicted postoperative FEV1 (ppoFEV1) was calculated using the formula: preoperative FEV1 × (19 segments-the number of segments to be removed) ÷ 19. The difference between the measured postoperative FEV1 and ppoFEV1 was defined as an outcome. Patients were categorized into two groups: preserved FEV1 if the difference was positive and non-preserved FEV1, if otherwise. In total, 238 patients were included: 74 (31.1%) in the FEV1 non-preserved group and 164 (68.9%) in the FEV1 preserved group. The proportion of preoperative residual volume (RV)/total lung capacity (TLC) ≥ 40% in the FEV1 non-preserved group (21.4%) was lower than in the preserved group (36.1%) (p = 0.03). In logistic regression analysis, preoperative RV/TLC ≥ 40% was related to postoperative FEV1 preservation. (adjusted OR, 2.02, p = 0.041). Linear regression analysis suggested that preoperative RV/TLC was positively correlated with a significant difference. (p = 0.004) Preoperative RV/TLC ≥ 40% was an independent predictor of preserved lung function in patients undergoing curative lobectomy with mediastinal lymph node dissection. Preoperative RV/TLC is positively correlated with postoperative lung function.

RESUMO

BACKGROUND: Many chronic obstructive pulmonary disease (COPD) patients receiving monotherapy continue to experience symptoms, exacerbations and poor quality of life. This study aimed to assess the efficacy and safety of direct switch from once-daily tiotropium (TIO) 18 µg to indacaterol/glycopyrronium (IND/GLY) 110/50 µg once-daily in COPD patients in Korea. METHODS: This was a randomized, open-label, parallel group, 12-week trial in mild-to-moderate COPD patients who received TIO 18 µg once-daily for ≥12 weeks prior to study initiation. Patients aged ≥40 years, with predicted postbronchodilator forced expiratory volume in 1 second (FEV1) ≥50%, post-bronchodilator FEV1/forced vital capacity <0.7 and smoking history of ≥10 pack-years were included. Eligible patients were randomized in a 1:1 ratio to either IND/GLY or TIO. The primary objective was to demonstrate superiority of IND/GLY over TIO in pre-dose trough FEV1 at week 12. Secondary endpoints included transition dyspnea index (TDI) focal score, COPD assessment test (CAT) total score, and rescue medication use following the 12-week treatment, and safety assessment. RESULTS: Of the 442 patients screened, 379 were randomized and 347 completed the study. IND/GLY demonstrated superiority in pre-dose trough FEV1 versus TIO at week 12 (least squares mean treatment difference [Δ], 50 mL; p=0.013). Also, numerical improvements were observed with IND/GLY in the TDI focal score (Δ, 0.31), CAT total score (Δ, -0.81), and rescue medication use (Δ, -0.09 puffs/day). Both treatments were well tolerated by patients. CONCLUSION: A direct switch from TIO to IND/GLY provided improvements in lung function and other patient-reported outcomes with an acceptable safety profile in patients with mild-to-moderate airflow limitation.

RESUMO

We report the growth, innate immune response, and disease resistance in olive flounder (Paralichthys olivaceus) challenged with Streptococcus iniae after feeding with diet enriched with Zooshikella sp. strain JE-34 three different concentration i.e. Low (3.4 x 10(4), n = 50), medium (3.5 x 10(6), n = 50), and high (3.4 x 10(8), n = 50) cfu ml(-1) supplemented diets, the changes were monitored on weeks 1, 2, 4, 8, 12, and 16. With all diets the innate immune parameters, such as superoxide anion production, phagocytic and lysozyme activity were not enhanced on week 1 and 4. On the other hand, all tested immune parameters in the treated groups significantly enhanced after 8th week; the weight gain significantly increased after 4th week in fish fed with enriched diets. The mortality in olive flounder after administration with high concentration diet showed 25%. With low and medium enriched diets the mortality was 40% and 35%, respectively. In the infected untreated group mortality was 85% while there was no mortality in the control group. The results suggested that Zooshikella sp. strain JE-34 enriched diets could be used to enhance the innate immune response and disease resistance of P. olivaceus against S. iniae.
